I'm looking at buying a Dyna CNC table top router for engraving and carving purposes. Is anyone familier with this machine? Do they have a good reputation? Is there any more affordable machine I could be looking at? The package cost< including a Computer,Software(Mach 3 & BobCAD,BobART)36"x36" table with 3" Z travel Axis is around $8800.00 Thanks JC

I am planning on buying one once funding comes in.

I spoke with the owner himself, he grew up locally and it seems as though they have the right idea. They over engineer their products and back them strongly, talk about customer service. I have heard nothing but promising feedback.

Did you request the DVD, its amazing.

I'm still getting the correct parts sent out and completing my driver wiring on the kit that i got from keling tech. I'll post pros and cons along with some pics when i get time. I'm also quite sure i'll have plenty of questions, this being a big project that is totally over my head.

Thanks for the reply. Yes , I got the DVD and spoke to the owner as well. I just wanted to here what there reputation was like. Thanks

I recieved my Dynacnc dec. 27 06. It is a 4x4 dual router plasma table. I am running PhotoVcarve on it without any problems that I havent been able to solve myself. Haven't done any plasma cutting on it yet,but that is next.I picked up my table myself and Steve Capp the tech support was very helpful.As Dynacnc is an open system the is no end of free tech support for everything on the web.

I ordered our machine just before christmas, It arrived the week of feb 9th. Some minor glitches in the geckodrives, but handled easily with the help of Mark in terch support. Still waiting on the 3-D software though, it was backordered. I will post again once the software arrives. BTW, we are a retail and commerical engraving shop, so this will be a major addition to our product line.

GEZZZZZZZZZZZZZZ Man!

CrashMasterKev you need to take a chill pillllllll.
I want to read about machines here not listen to cry babies. sssooooo you had some problems........don't care!

The man offered you your money back............take it and shut up man!

Dude......Your comments don't need to be here on this board! I don't own one of these machines but I can tell you this........

I am tired of reading your cry baby crap!

CrashMasterKev take it back to them I don't want to here about it. This site is educational to me but this crap is crap!

$2800.00 for a cnc machine......... wow. Where do I sign up! Thats a deal! I could see complainin on line if you spent like 20 grand for a machine or something, but 2800.00. you are kidding. Freom the sounds of your other posts....you don't know what you are doing! get an education and a life! chill and warm up to a nice warm cnc book and learn like most operators.......... The dude from Dyna sound like a pretty fair guy to me and you trash him on line ......bummer CrashMasterKev, dude you are the loser here.

advice: go somewhere else with your trash....:rainfro:

That was interesting!

I can see both sides on this one. I don't think Kevin is just "crying". He purchased a machine, concessions were made to appease a customer when delivery was obviously not going to be made. And then those concessions turned out to be unsatisfactory.

The other hand....dealing with the glitches in a company that cause you to be late. Going beyond your requirement of a contract to make up for a delivery issue...and having a customer upset with the quality of a free extended service.......Frustrating on both ends.

Business goes this way sometimes....you both have a goal...to make quality products for a profit......Why not send a tech to help Kevin get this machine set up so that it makes absolutley mint parts. Teach him a couple efficiency tips and watch him make perfect parts on a perfect machine.....then he will brag about your product to his network until his business expands and it's time to buy a new machine.......Full Price of course!

Guys, I can appreciate all your views, keep an eye on this post for my reply coming soon, and you’re right snuffy plaz, this isn’t the place for this crap, but I was never heard before when I tried to deal with this one on one with the manufacturer, so maybe he will try to help me now, I to hope that we can get all this resolved. Trust me I dont like this anymore than you do.

You can also post or pm me your email and I will email you .

Ok Dave, Maybe your right, maybe I did blow this out of proportion, but I feel like maybe your company never took it seriously enough when I contacted you about the issues we’ve been discussing here when they were fresh.

I understand completely, I have been in your position and that’s why I tried to forget about it and tried to make the best of a bad situation and just deal with what I have, that is until I saw someone inquiring about your company, in my opinion, I got burned and there was nothing that I could do about it, that is what a representative of your company told me.

Dave, I am an honest hard working person like yourself, and I swear to you Dave, I was never contacted about the ball screw issue, please show me your documentation that proves otherwise, you keep saying you can and I have yet to see it, I have saved all communications between your company and myself in both hard and electronic formats and there was no discussion that I wasn’t getting servos prior to receiving my machine so I would really like you to show me when that was because it’s not in my records.

I tried to remedy the situation as soon as I realized that what I got was not what I ordered and not what I paid for, and it was pointless, I was told I could send it back and eat the shipping both ways, Dave, I cant afford to eat $700.00 in wasted shipping costs, so, I decided I try to make the best of it, after all, I’m a reasonably intelligent person and there’s lots of people out there running steppers, so they can’t be all that bad, right?

Well, even with your configuration, standard screws and steppers, the machine is undependable, I have trashed hundreds of dollars in material and hundreds in broken bits due to missed steps, it only takes a few missed steps to trash a part or a tool, I have tuned the motors till I was blue in the face, and its better, but it’s still not right, it’s not what I bargained for, that’s why I wanted servos.

You may be thinking that I am a rookie, and that maybe this is all operator error, let me tell you something, it was about 10 years that ago I attended a CNC programming/operation course at Thermwood Inc., and yes, I have the documentation to prove it, Since that time I have been employed in various positions all related to the operation and programming of CNC’s and I have thousands of hours In my profession, I currently and daily use AutoCAD 2007, AutoDesk Inventor 11 and Planit Solutions AlphaCam V6 to program 4 busellato point to points and a CMS machining center, I feel very confident that I can handle the programming and operation of my DynaCNC.

With that said, I don’t feel that I know it all, but I feel that I stand as good a chance as anybody of being successful at programming and operating anything that anybody can throw at me in the world of CNC’s but I can’t seem to overcome the issues of the product I have purchased from you.

Ok, so, I just read the last couple posts and this is what I am thinking at the moment.

You know what Dave, snuffy plaz is right, we shouldn’t be discussing this here, this really isn’t what this forum is about, and I don’t feel that it is beneficial for either of us, especially you, to continue to do so.

So, Dave, if you would like to contact me at you earliest convenience, Monday or Tuesday would be fine, we can both put our pride aside and take care of business, I would be willing to try if you are.

And I believe that I have the solution to the problems I have been facing and you might be able to produce a better machine for your customers, and avoid issues like this in the future, we both win, I truly believe that I know what the problems are and it’s a fairly simple fix, you probably have the parts on hand, and you know that I am a very outspoken person, if we can get this fixed, I will tell the world that you helped me and you can feel even more confident in your products. WIN WIN situation. Give us a chance to fix this.

Now it’s your turn Snuffy plaz, as much as I don’t appreciate you calling me a crybaby, I see your point I respect it, and, I agree with you, this isn’t the place for this, BUT, I don’t think that you or anybody else here would be very happy in my situation, there is way more to my frustration than you are aware of, I tried to keep it simple and to the point.

What you have heard here just scratches the surface of how this purchase unfolded, think about it, if you spent your money, whether it was 3K or 300K and upon delivery it was not as you agreed upon, you’d be upset to, I kept my mouth shut here, maybe for too long, but it is what it is now, I hope we, that is, dynacnc and I can work this out.

Also I hope you read my qualifications, I have the books, the education and the experience to program and run just about anything.
And I’m glad you’re here, I think this is a great place for education, I have helped many people here and I have gotten help here, and maybe you can do the same someday, Welcome to cnczone, It’s too bad that you blew your posting “virginity” crying about me crying.
It’s all good dude, no hard feelings, I’ve been dealing with it so far and I will go on.
Hopefully we can work this out.
Have a good one.
Kev

There goes the good ole declaration that the customer is always right!
Daivd I have to say it was pretty inappropriate for a businessman such as your self to hash this out over the internet. Right or wrong! I don't own a Dyna but at one time was looking at them. Not anymore.

Mr. Watts,

Sorry to lose you as a prospective customer.

Sincerely: Good luck with whatever you do decide to purchase.

I apologize you are offended by the correspondence, however I did state that I normally do NOT conduct business or answer these types of posts on the Internet. I feel we did everything possible to provide this customer with a good conclusion to the problem. It was his choice to bring it to the Internet and my choice to answer this problem here.

I hope in your business you do not have to protect your interests over the Internet. Watch closely, it will happen to every business including yours.

I do believe in freedom of speech and the right to state anything on the Internet or anywhere a US citizen decides to speak. I have no problem with honest evaluations. That includes my staff and me. I do have problems when facts do not add up and people have to pay a BIG price for inconsistent statements.

Unfortunately most people believe everything they read on the Internet regardless if it true or not. People relish in problems and turmoil that is sensational. Sensationalism always gains interest because people love to hear about other people’s problems.

For myself: I don't believe everything I read on the Internet, newspapers, or media. I don't like sensationalism. I don't put down, condemn, or ridicule people, vendors, or customers anywhere. I listen, evaluate, and place a solution into action. Kevin received an offer for a full refund as well as free shipping back to our company. I can't make it any better than that.

Good luck with your future purchase and have a prosperous 2007,

You know I've been sitting back and reading as much as I can about CNC routers and trying to learn a little. I’m learning a lot!!

There goes the good ole declaration that the customer is always right!
Daivd I have to say it was pretty inappropriate for a businessman such as your self to hash this out over the internet. Right or wrong! I don't own a Dyna but at one time was looking at them. Not anymore.

While I enjoy watching a good cat fight as much as the next guy I don't think this is the forum to present a case in the court of public opinion. Neither side comes out looking good. As a small businessman myself I can understand the reaction to defend your company. It's your baby and you have put everything into making it go and it's easy to have that unraveled by what you feel are misleading or false statements. As a customer that has been treated poorly at times I see that side too, but I have learned that the best approach is not a public head-on collision.

Actually Mr Watts, it's the silence from some of these manufactuers that is scary. I know of several out and out crooks out there selling tables, but you will NEVER see them post on any list. They know that when customers complain, and there is no response from them, that the thread quickly dies and the can go back to delivering junk.

If you think you are good enough to evaluate a product across the Internet from looking at pictures and reading the website (expecially if you judge the company by the website look and feel) then you are a ripe target for being really ripped off.

Yes, I have a dog in the hunt (as they say in Texas) since I supply controls to several OEM accounts (DYNACNC being one of them) but I also have embedded knowledge of how these support issues can mushroom out of control. I get dozens of e-mails a month from users with horror stories of poor support or just plan nasty tactics from names that would be familiar to you. Without exception those companies won't respond on an public forum and they have been known to delete negative posts on their private support forums (if they even have one).

Personally. I think this specific issue had been fought to a bloody draw.

Dave probably needs to review his organization and possibly give some direction.

CrashMaster needs to either take the refund that has been offered or keep the machine and deal with it as is. Things like pulleys being bored wrong are irritating, but you can buy off-the-shelf pulleys with specific bores a dozen different places for a few bucks. There are a multitude of sources to help him resolve the other issues as long as it's civil. None of these machines are that complex and there are hundreds (if not thousands) of persons on this list and others that can offer general troubleshooting proceedures and cures.

That's my story and I'm stik'n with it!:wave:

The saying that the customer is always right is the worst statement ever said in the history of the buying/selling world especially now that the days of “a handshake seals the deal” are over.

One must remember that it’s a buyer's market out there and far too many consumers take advantage of this. There are people out there who put glass in their meals to get rid of a check and there are people who wear items once and leave the tag on for return so they can look good at a one time event.

Is it wrong of companies like Wal-Mart to restrict the amount of returns a person may have in a given amount of time? As honest consumers we look at this as an inconvenience for ourselves. However, as honest consumers we pay the price in the long run for the fraudulent actions of others. I am not saying that this is a fraudulent accusation by Kev, or mean disrespect to him in any way, but he as a business owner needs to look at this from a business owner’s point of view, not a consumers. Kev, if you do not have employees under you, this may be impossible to fathom.

As an owner you rely on those under you and accept responsibility for all those under you. I have never seen a shop where a piece was shipped as a bad part and the buyer called the man who machined it, they called the owner of the business who did. The owner would then check his own records, ask for proof of error by the buyer, discuss the matter with the person/persons involved in the error. Then in the case of error MAKE IT RIGHT.

Usually this process is done on one on one correspondence. I am sure that Dave is not hard to reach through phone or email. Instead this was done for the whole world to see. In my eyes this was what the consumer wanted. Kev was testing Dave, and all of you reading this should be humbled in the fact that a business man who is so sure of his ethics is willing to give you real-time witness of humility, admittance of error for his company’s mistake, and then finishing it with making it right. The only hostility shown by Dave through all of this was nothing more than the agitation that Kev took advantage of the situation by being able to go into the argument with the opportunity to make DynaCNC look bad if he pleased. I don’t feel that he did this, if he fails to take the offer of free return then he is making the mistake and in doing so is undeserving of the offer in the first place.

The bottom line is that Dave took the fault and admitted a company error. I don’t know about you potential buyers out there, but I know that no company is perfect and I would pick a company whose owner fixes their mistakes over a company that wouldn’t even make it right or worse yet send a customer service rep who says that I am authorize to only do this much and not get anywhere using up time and causing added stress.

Three cheers for the guys like Dave out there that make business look good and make things right and shame on those of you who make the fraudulent claims in the world (this includes the business owners descrbied who don't have the (nuts) to stand up for their product because they know it's junk). If you didn’t exist, when this stuff happens, it wouldn’t be a big deal to make right the errors made to those who are honest.

Hi,

I'd like to state up front that we're completely satisfied with the two 24" x 36" router table kits that we purchased. Alirght, here's the catch, I wasn't happy with the customer service, and the kit being ready 5 weeks late. We ordered two kits in the first week of December and they weren't ready until mid-February. This wouldn't have much of a problem if Sandy had just been straight forward about their growing pains and followed through on returning my calls. Another strange experience was when we arrived at Dyna CNC to pick up our kits. We entered the office, and the lady behind the window looked at us and quickly disappeared. We sat in the waiting area for about ten minutes, and then Sandy greeted us and gave us a quick tour. He's as friendly in person as on the phone!
I asked Sandy if the kit came with a router mount, and he replied "It comes with a Porter-Cable mount." Sandy had to get the phone, so the shop tech helped us load our kits up. When we asked him for assembly instructions he said they didn't have any. I didn't get his name, but he seemed put-out by us being there. So, we drove back to Portland, dropped of my kit at my shop. Upon inspection we discovered no router mounts, so I called Sandy the following business day. Sandy said he'd email the assembly instructions, and check into the mount for me. He claimed that he'd get back to me the next day. He didn't, so I called him two days later, and he stated that the kit didn't come with the mount and that he'd have to get approval to honor his commitment. I got the instructions a week after pickup, and I only called Sandy one more time about the mount. He never got back to me, and I decided not to pursue it any farther. Currently, my buddy and I each have our machines running and are happy with them. We both run small businesses, and would loose customerst if we communicated this poorly and innaccurately. I'm not trying to discourage anybody from purchasing from Dyna CNC, but wanted to share my experience. Hopefully they'll address these customer service issues.

Thanks,
Terry

I think they already have. Sandy is no longer with the company and there has been some "realignment" in tech support and other area's.

I don't think Dave was totally aware of some of the things his people were doing (or not doing). I know your employees are your company but they don't always operate with the best interests of the customers in mind. It's like judging a family by it's teenagers (:-).

I have seen this in big companies and small. Somehow customers start to be considered to be a nuience. The good news is that there seems to be a genuine desire to get things corrected at DYNACNC. I can tell you that most companies would not admit to mistakes or even engage in a public debate. In the end the owner has to make hard decisions and put things back on track. DYNACNC builds a good solid machine and has enough units in the field to say that the level of problems are low for the quantity involved. I know that doesn't help the guy that gets a machine with problems but I think you will start to see those issues addressed.

Only time will tell! I think that they sell a great product for the price, and may consider doing business with them again.

I too have ordered the 24x36 kit. I have spoke with Sandy several time except for the last time I has a question. I was also told that he is no long with their company. On my initial contact with Sandy he told me that this router should use steppers not servos. Not sure if this is really true or not but I was told that servos were not recommended. I didn't think twice about the comment as I wanted steppers anyhow. I have placed several calls to them about questions before and after my purchase. Some of these placed calls were answered right away other I had to leave a message. The times that I had to leave a message they called me back the same day. My last call was to verify stepper driver configuration for the y axis. I left a message in the morning. Melody called me back mid afternoon, apologizing for it taking so long. She was not sure of the answer to my question so she had Mark (who assemble these tables) call me back. He called me back a couple of hours later and answered my questions confidently.

My experience with DynaCnc to date has been good. Every one that I have talked to have been very pleasant and helpful (Sandy, Melody, & Mark). Would I like to have had my phone call answered by a person right away instead of leaving a message? Sure, but getting a call back the same day was fine. My router has not been delivered as of yet so I can not comment on them meeting delivery times or on quality. It been 4 week now so if they meet the 6 week timeframe I should get delivery during my vacation I have scheduled. I any are interested I can report back my experiences when I get my table.

Hello Dany CNC

If you get that table back, I would be interested in knowing the price. Maybe I could talk my banker (wife :) )into freeing up some $$.

We have our two 24" x 36" up and running now. I have to say I don't recommend these kits for beginners. There's a lot of tweaking involved, and there are easier alternatives. We've had specific problems with both machines having excessive backlash(0.030") on the x-axis due to the leadscrew having no support bearing on the drive side. Both kits had bent leadscrews, and poorly machined ends on the y-axis. The setscrew grooves on the linear rails are unevenly machined. They appear to be done by hand. The machines run about half as fast as our K2 machine, and aren't nearly as accurate. Due to these issues we are unable to use these machines for our more detailed parts. I get the impression that the kits aren't given the same attention to detail as the turn-key systems DynaCNC offers.

I want to make it clear that I'm not bashing DynaCNC, but objectively sharing our experience. I think that it is appropriate to judge a company it's service and product quality. All in all, if I had to do it again, I'd spend a little more to avoid the setup and quality issues.

Finally had first movement.
-no smoke
-no broke machine parts
-wood part that almost looks right
The fastest i can get out of it is 20ipm without loosing steps, unless its some settings i screwed up. I was hoping for closer to 50ipm .

I am useing 425 oz steppers not sure weight of gantry,keling 3225drivers putting out 2.52 amps and 24volt power supply . anyone have any ideas how fast i should be able to get?

Based on the leadscrew and the voltage you are using I would say that absolute top speed with everything perfect would be 30 IPM. That comes from the fact that the motors will only do about 350 - 400 RPM with 24 VDC. I think those leadscrews are 10TPI Directly coupled they would give you 40 IPM but I think they may have belt reduction(?).

If you want more speed up your voltage (if the stepper drives will take it) to 48VDC). You may need to upgrade to the keling 5042 drives that will take up to 50VDC. RPM comes from volts. Bigger motors won't spin faster and some actually have worse high RPM specs than smaller motors. If there is belt reduction take it to 1:1 or try swapping the pulleys to get belt increase

Check here for a good price on a 48VDC supply that should drive those motors. http://www.bgmicro.com

The good news is you should have good resolution.

-I think these drivers are only good up to 32 volts so building a new box is a project for next winter .

-yes 10tpi acme
-and yes I do have the y's at 1:1 which i could gear up but z and x are direct so i'm out of luck

-also the drives are set for 1/2 step because i have visions of more detailed pieces Iguess i could get speed there

I'm a beginner in cnc I thank all for there help, hints and tips and is very much appreciated. Also thank you Dave and Mark for fixing your mistakes and standing behind your machine. The smile I had while ordering your kit is returning::)

Hi,

Our speed problems(racking and binding) were due to poorly machined leadscrew ends, and the x-axis leadscrew being unsupported at the drive end. Something the motor manufacturers, for good reason, say not do. So much for the claimed over engineering! We've since upgraded to ballscrews and installed support bearings on the unsupported ends. I'm also running 425 oz steppers, and can run reliably at 75ipm. My partner runs at 120ipm reliably with a slightly different setup. I will be posting a summary (conclusion), with pictures, of our DynaCNC experience within the next week. Again, I want to make it clear that I'm not bashing DynaCNC, but only summarizing our experience with the two kits we purchased.

Thanks,
Terry

I am friend of tohlsson. We've each purchased a dyna kit that is advertised on ebay.

I would just like to share my experience. first my background.
this was my 4th CNC. I have K2 25-14 as well as taig cnc(which was my first) I also have converted mini mill using cnc fusion kit. I also work with motion control and have extensive experience with various CNCs as well as programming. I do run a side business that is doing quite well and I needed a bigger CNC for my expanding business.


We basically saw a good deal on ebay, and since they were within driving distance, with what I could find out, it was a great deal, and we figured we can make anything work. we were bit concerned about the ebay ad, which left out lot of details, but we talked to sandy and felt that they were legitimate.

We ordered the 2 machines in early November. We were told to expect 5-6 weeks to be ready. we figured we will have time over the christmas break to put it together. In the end, it took more than twice the time. I can understand being delayed, but least they could give us was good ETA. rather, it was always "next week" I guess sandy is no longer with the company, and may be they fixed this issue. eventually, we were told our "kits" were ready, and this was mid feb. (weekend before president day)

I will not get into our experience picking up the machine, but will talk about the machine itself.

We've noticed that end of the lead screw were not machined well. it was bit off centered, but we figured it was usable. Machine is primarily made from 80-20 aluminum and base is pretty solid. about 200lb+ Lead screws were 10:1 acme with bronze nuts. the linear bearings are simple ceramic ones without recirculating balls. machine overall looked nice but there were some poor machining on the linear shaft and the lead screw ends. Also, we initially noticed that x axis was only supported on one end. on the stepper end, it depended upon the stepper motor for support. this is also true for z axis. I am using 280oz steppers on all the axis with 4 channel xylotex drive. I use this on all my other machine and have gotten reasonable performance.

after much fussing(due to lack of manual) I got mine up and running during the president day weekend. I was getting about 30" /min on most axis, 40" on Y axis.which was acceptable. the Y axis leadscrews though were not smooth at all due to poor end machining. center of leadscrew would move about .5" up and down. the bigger issue was back lash on the X axis. I had preloaded the stepper (which is hard on the motor) the best I could do was .030" backlash just from screw moving. with compensation from Mach 3, it would cut reasonably.

for about 2 weeks, I tested and ran the cnc cutting parts for my business. after about 2 weeks (about 20 hours), I've started to see backlash on the Y axis as well. (nut was wearing in, as it was not self compensating) For next month or so, I messed with setup, etc but it just was not going to cut to accuracy I need. I still had my k2, which has performed fairly well for over a year(it has its own issues, but I won't get into that on this post)

anyway, at this point, both Tohlsson and I've had enough with trying to make this work. I suggested that we need to fix this setup right, and we've decided to replace the lead screws with ball screws and nut and redesign the x axis to support the stepper end.

I've measure the length we needed and place an order with www.homeshopcnc.com for nook 5/8" ball screw with preloaded nut for our 2 machines. since z was working ok, we only replaced the X and Y axis, and we had the ends machined for us. total cost was bit over 1000 bucks for 2 machines. We've received the ball screws which took bit over a month (I guess nook is having supply issues) very nicely made

The end block had to be machined down and tapped with 15/16-16 tap. (machining required so that nut will clear) this was done easily using a bridgeport knee mill and using a tap we purchased. the head block was already tapped for this thread, so did not need more work. about 2 hours of machining time and ball screws was ready to install. we also added a end plate with support bearing for the x axis and move the stepper using spacer.
figure half day of work and another half day of disassembly/assembly.

after it was put back together, I am now able to run it at 100"/min on each axis (It will run at 120"/min, but I like bit of margin) it is also very smooth. most of my cutting is done at much slower speed. no vibration and no backlash. (about .001" and tohlsson is getting .002") Now I am a happy customer.

kit now cost 1500 plus ship. (we got ours at 1300 before they raised their price) figure 550 for new lead screws and parts. another 450 for stepper/control. so, 2500 or so invested plus Lot of time spent machining and modifying. for all the hassle, i would have been better off buying K2 4025. Still, I now have a solid little machine. I will probably end up designing and building my own machine next though. oh yes, total travel I get is 35x23.7 after the fix. originally, I got 35x25.

Tohlsson will be posting pic and his own experience later this weekend.


I hope that dyna can redesign and fix this kit. overall, this kit has pretty solid base. all they have to do fix the kit is following:

1) isupport the x axis lead screw on both end
2) change out the bronze nut to some form of compensating nut on x and y axis.
3) get a better control on their machining.

if they fix these issues, I believe this will be very good kit for the money. if they make a small change to the design, they can even add ballscrew upgrade for substantial more money.

With that out of the way: If anyone at all has any grievances, any fears, or any questions regarding DynaCNC products, they can reach me through the CNCZone via this user name. I also urge you to contact me via instant messaging at epiksolutions @ either msn.com, or yahoo.com. For email, please use the account tyler@epikltd.com, all of my private messages reach this box as well.

As a distributor of DynaCNC, I feel that is important that I look into any feedback regarding our products. As with any product, no product is perfect. However, the road to machine perfection is paved with the experiences of our customers. If you have suggestions, please tell us.

I must get off of here soon as a storm is approaching. I will be back on if things clear up. I see that many people are viewing this thread, and I would like to make myself available to them if need be.

I thank you for all the constructive criticism. And as Kev pointed out, Dave is proud of his company; with much reason to be. As a distributor, I am PROUD of his attitude towards criticism, and feel that his attitude is what has made DynaCNC a forerunner in the industry.

Please do not forget that we are not just machine makers, but we are customers ourselves. I thank you all for your support as well as criticism, and wish you all the best. I speak for both Dave and myself when I say that we are here to serve you. Your success is important to us, and is essential for our own success.

Good evening Tyler,
Let me start by saying I commend you for wanting to stand behind a product that you distribute and even wanting to get involved in this situation.

I am open to remedies to resolve the issues at hand, however they are not as simple as a refund to shut me up.
All I want a machine that runs reasonably well.
THAT’S IT!
That’s what I paid for, that’s what I expect, and I hope that that is what the manufacturer would want his customers to receive.
I hope to hear from you and I hope to come to a resolution that changes my opinion on this matter.
Thanks,
Have a good weekend,
God bless our troops and the veterans that have made this country what it is today.
Happy Memorial Day.
CMK

Hi Kev,

I feel it would be more appropriate if we were to discuss this in instant messaging or in CHAT. Less typing, more one on one... more personable.

I want to elaborate on your closing. It is our troops that give us the freedom to choose what businesses we wish to do business with. Because we have that freedom of choice, it is necessary that a business looks good to future clientelle, as well as return customers. I was once in your shoes looking for a machine. CNCZone is where I found my answers. It is the gateway to many newbies and potential machine buyers, and it is essential that potential purchasers get the truth.

I am sorry that DynaCNC has not met your expectations. I will sit here, and refuse to state that the product is not capable of "running reasonably well". I accept the challenge of making you happy, and will tell you now that Dave and I have spoke of your situation, and he doesn't know what else to give you! You have established what you want... now, tell ME what it will TAKE...in detail. Be specific.

As witness to all reading this, you admit that Dave has done what most everyone else in the world would consider the ULTIMATE apology by refunding. Apparently you want a little more. If you promise that you will quit running my partner and friend's name in the dirt, and become a supporter of DynaCNC because of our service, I will gladly help you. On that condition.

If you don't, please understand that you are only making yourself look bad to your peers. You seem like a decent guy and I don't want you to do that to yourself. The situation has already been solved, and most would be impressed at how Dave handled the situation. There is not much more that could be done, if at all there is anything. Consider this an act of friendship between CNCZONE members. We are a family, I don't want the others to look down on you. Let ME help YOU.

Tyler

askman could you please post pics of your upgrade/fix. I'm sure I'll need to do the same to my machine to satisfy my expectations . I'll post my story once it has an ending.

tohlsson will be posting complete picture/report this weekend. if he does not, I will.

thanks tyler for contacting me. I do hope that dyna can get the design fixed. that is the first thing they need to do. once that is done, they will have lot less complaints.

Very happy to be of your service Askman.

Because the number of you experiencing problems, please conglomerate your headaches into a WORD document (with pictures) for me, and I will forward it on to Dave --- tyler@epikltd.com. From there, I will see if there is a simple solution to all this.

Once again, I will state that you all purchased kits. As with anything, a kit will work in theory. Small errors on either side can ruin everything. However, I guarantee you that Dave would not send you something incapable of becoming a useful machine; when you stand behind your product, you don’t send crap out, crap stinks to stand by (pun intended). Lets be practical guys, to reduce costs, the Ford Motor Company does not send cars in kits for the buyer to put together. Too much can go wrong, please be thankful that you even had this option, it saved you a pretty penny, and now we, as long as yourselves, are left with the headaches. I apologize for any stress this situation may have caused.

I cannot, and will not speak for Dave. However, as a distributor, I feel obligated to bring up your situation to him. Once again, please put together an honest complaint and I will see what I can do. I will not guarantee that something will be done, kits are sold as is---for an honest reason…you all saved your money, but I can state that if there is in fact a legitimate claim here, things will be changed.

I thank you all for your maturity in this matter, and hope that you find a way to make your machines the money making pieces of equipment that they are. DynaCNC and EPIK are here to make you all more successful than you already are. Gentlemen, let the success begin.

I will respectably disagree. not all of the people here are kit buyers. beyond that, if you are going to sell kits, you have to make sure that people buying the kits end up happy. otherwise, you are worse off than not sellling kits at all. May be it is a tougher proposition than selling full running machine, but I believe you can minimize the issue with good design and execution. may be my expectation was too high. still, .030 backlash is not acceptable IMHO. and people who buy kits are the ones that will buy bigger machine later on, as well as give references. nobody said being in business is easy, but with competition, customer feedback is very important. it is much easier to keep people happy from the beginning.

Let me give you an example. I bought K2 2514 kit (basically full machine without the electronics) it was mostly assembled, but stiill required bit of tuning and final bit of assembly to make it run the way I wanted it. beyond that, I had one lead screw that had issues but they replaced it right away, no questions asked. no manual either, but no problem putting it together. it has been running well for over a year now. may be dyna should do the same for bit extra money, if they think poor user assembly is the issue. frankly, I disagree.

I would have done few different thing, if I was the design engineer.

I realize cost is important, but I would charge(and willing to pay) more for better machine.

1) go with recirculating linear bearings vs ceramic bearing on x and y axis. (z is not as important, as it is much shorter and lighter)

2) fully support the X axis lead screw on both end (requires 1 plate, 4 standoff and 1 flanged bearing with bit longer lead screw)

3) make the Y axis travel so that it is full 36" or even bit more. (there is enough room on the table, just need about 2" longer lead screw and rail shaft)

beyond that it will be nice to have wear compenstaing nut on x and y axis.

if I could have have had a good accuracy, 30-40"/min jog speed would have been good enough for me. (or for most people in this market)

anyway, thank for your attention.

I have glanced at a majority of the replies in this thread. Most of the complaints regard kits. I will not go into these situations, as none of them relate directly to EPIK, I am not able to comment. Kev's complaint was with the equipping of the machine, out of my hands as well as Dave's. Dave made that right as well as he good, plain and simple. In fact, none of these are my sales, but I am willing to look into what you all want so that I can take care of future clients to the best of my abilities. I thought his anger was settled in March, apparently it was not. Personally I am a ball/servo combo guy and would not buy anything else...I know where he is coming from...but I would have been cured from my hate after Dave made things right.

Dyna is a company that embraces cutting edge technology, that involves taking ANY and ALL feedback into the design of the machines. For that, I must thank you all for pitching in. Negative feedback, regardless of its origins, is what opens the road to perfection. I do not mean to be nosey, but before you all made these drastic modifications, did you guys contact Dyna to see if there was a reason things are the way they are? Forums are great when you can't get help straight from the horse's mouth, but DynaCNC stands behind their products, if you have a problem JUST ASK!

The thing that makes this hard, is that out of all the machines sold, there are only a few unhappy souls. The kits are the same things that get sent out assembled...as well as tested to extreme tolerances. So it is necessary to ask where the problem lies. I am in no way saying that any of the errors are your fault, it would be impossible to know this from my seat. Dave and I were both talking about it last weekend, and I thought he was just kidding when he said that when people hope he can't sleep at night, he wished they knew that he really can't. Look at the times of my replies... it should be obvious that I am no exception to that statement. We are both business owners ourselves, we know how much this stuff hurts. We've been there.

Anyways, I am strongly trying to pressure Dave to quit selling kits altogether if it gives us this sort of a reputation. EPIK will not be selling kits---singlized parts, yes. Kits, NO. I personally refuse to stand behind something I did not fully test. Sorry to break anyone's bubble, and deter any potential clients, but too many individuals rely on the machine to be up and running for my business to take the risks. In fact, EPIK does more than just distribute these fine products, we are consultants, any bad feedback on DynaCNC, is bad feedback on the company as a whole. If I put my whole company on the line for these products, imagine how far I will go to stand behind them. Please take a moment to dwell on that.

Anyways, thanks for the feedback guys. I will pass it on to Dave. Enjoy your Memorial Day, and remember what they gave for us. In comparison, all else is trivial. I hope we can all work this out. It genuinely hurts to know that you are unhappy with the DynaCNC products. If any of you return to the market in need of a machine, pleae be sure to check back in. Your complaints may no longer be an issue, and we want your business. I fully believe that our products can make you successful, and we want you to be. Thank you for your time gentlemen, I will check back in soon. Otherwise, you all have my contact pts.

Thank you

I'm quite familiar with DyanCNC products & if I had to do it all over again, I'd find another supplier. Reasons why I would suggest another firm? How about poor workmanship & piss poor tech support. When I received my unit there were parts floating around in the control cabinet & wiring that had come free from their cable blocks. They use nylock nuts, a good move (some would say) to curb loose fasteners thru vibration, but if the screws aren't long enough to take advantage of the nylon, what's the use? Tech support is nonexistent. I had a major problem with the THC section they could never figure out. DynaCNC's own Tech Support rep suggested I contact their supplier of the electronics. Had to go to Tom Caudle of CandCNC to get the answer. I can't tell you how many DAYS & DOLLARS I spent, dead in the water, because DynaCNC coudn't get it right. In the industry there's an acronym called CRM (Customer Service Management), in summary it's a method of how to keep customers. Dyna CNC has re-written it to read Customer Service Mismanagement. As you can see from previous emails, Dave Cress has undertaken the job of damage control. I believe that speaks volumes.

I hope that dyna can redesign and fix this kit. overall, this kit has pretty solid base. all they have to do fix the kit is following:

1) isupport the x axis lead screw on both end
2) change out the bronze nut to some form of compensating nut on x and y axis.
3) get a better control on their machining.

if they fix these issues, I believe this will be very good kit for the money. if they make a small change to the design, they can even add ballscrew upgrade for substantial more money.

Thank you for your productive comments; To answer your above remarks:

1) We have an option that contains the lead screw on both ends of the "X" axis. It was added a month ago to our fully assembled machines.
2) For the money this is the best long lasting nut we can produce. We have tried other plastic compensating nuts with less success. Backlash compensation can be accomplished simply on Mach3.
3) Also, about a month ago, we purchased a Miyano CNC lathe just for that reason. All of our lead screws and drive shafts are machined to very precise measurments on our cnc lathe as of the beginning of May 2007.
4) We have offered a ballscrew option from the beginning for a very good price. All of our "fully assembled" Table Top Machines with ballscrews run at over 100 ipm.

Considering this chassis is sold as a kit for $1500.00, it is designed to get people off to a good start of owning a small home workshop cnc machine. This same machine with all of the options costs $5300.00 +-, fully assembled at our factory. The chassis kit was designed for the folks bidding on eBay to get a solid chassis they can "add to" and "modify" into a machine they can use for their individual reasons.
I hope this clears up the issues stated above.

.....I had a major problem with the THC section they could never figure out. DynaCNC's own Tech Support rep suggested I contact their supplier of the electronics.

Ahhh, just what makes me REALLY happy. Helping to get a customer running with their THC and then getting dished for the effort.

You can bet I'll jump through my ass to help you in the future.

Ya know ya get what ya pay for, at work we hammer a Komo vr512 16hrs a day 5 days a week, and it just keeps running and producing parts, week after week, month after month. Its boring. Yep ya get what ya pay for 280k vs 2.8k

Hmm, i just sent Dyna a price request and if the improvements they made lately have an positive effect, its worth a consideration. Otherwise the offer goes to the made in china files and i will think multiple times before buying one of those because like most of the customers, iam not and i dont want to be a CNC expert/programmer, that`s not what i do for a living so i want a boring machine.
Like many others i`ve been looking for a CNC for month now because for some of us this may be the biggest investment standing in our shops, what i want to say is, that if CNC newbs like me can spend that much time in research, comparisons, learning about parts and what they do, the manufacturers can spend 1-2 weeks testing their products.
The expression "You get what you pay for" is relative, a cheap fridge may be loud, less efficient and last for only 2-3 years but within this time, it should do what it was built for.
So there is no excuse exept for making up for lost money, customers, reputation or time caused by a manufacturer who can`t check his products every now and then.

IMO, the customer is not always right and he`s certainly not king but i like to think about it in a simple and practical way:
An employee gets his money from his employer, from whom does the employee AND the employer get their money? You guessed it.
That doesn`t mean that you have to smile 8 hours a day, in fact you don`t even have to be polite to sell your product but a certain level of competence, tone of voice and patience should be standard, everything above that can be nice but is not a must and everything below that makes the customer feel disposable. Where i come from, they are called "filled up sellers".

Be sure to shop around! In my opinion, and experience, there are better American made alternatives in the same price range. My Dyna macine (24"36 almost) now will do what I need it to do , but only after a lot of tweaking, and extra dollars. Be sure to note that due to the use of unsupported rails, mounted too closely, in the x-axis there is a lot of deflection under load. I strongly reccomend a machine with fully supported linear rails!!! Also, the unsupported screw ends in the x and z axis will shorten motor life. The motor manufacturers strongly suggest not to do this because it creates lateral and axial loads that the motors aren't designed for. If Dyna has corrected these design weaknesses, then maybe I'd consider buying another one. But, as it seems, the benchtop machines on their website look to be the same. There seems to be a lot of hypersensitivity to the around their customer service issues, so I'll leave to others to discuss. Although, my experiences were not very positive...

Thanks for the tips tohlsson, a 1 man manufacturer told and showed me just what you wrote. From what i understand, ball screws alone don`t make sprecise and sturdy machine, some of them get special heat threatment to make them harder, there are different ways in housing the ball screw ends, the rail systems etc...
The machine he showed had all this features and was running for 3 years just with some oiling every now and then, well he wanted 7500,- (38x50 xy) for the stepper version with some software and a mdf plate, no table, no legs, no router, no safety switches no nothing.
Right now i`am looking for a machine with the minimum specs of 38x50 or 49x96 xy and as usual, the price is a major factor when opening a shop.
Thanks to the tons of informations at CNC-Zone, i`am at a point where i have to decide between a smaller one with good quality, a bigger one with the risk of repairing more then producing or a bigger one with good quality but less money reserves for other things that may come up.

Thats one nice balance act between productivity, cost and quality i still have to figure out.
At the moment a good used one seems to fit well into all of the 3 factors.

I agree with TOHLSSON'S first sentence.

I have a dynaCnc kit and have run into the same sort of problems with it. After remachining much of it it and replacing the bronze bearings with plastic it still will only run about 25ips on x and has some very bad vibrations. The bearing mounts on the x axis were machined about 30 thousandths off so I had to make new mounts and put them on the other side of the machine where I assume ball screw mounts would have otherwise have been. The Y axis binds near one end. I'm still fighting with the thing, not exactly sure how to fix the vibration. I'm thinking of mounting bearings on both ends as one of the other posts suggested.

Hello everyone, this is my first post. new man. got a question if anyone can answer. Does anyone have documentation from their experience using powermax 1000 regarding metal thickness and speed of cut using Fine cut or standard tips. It would be great help getting these setting for my new machine.
