Dave Rigotti, (Or Others with Knowledge of the HOBBYCNC Boards)

I am seriously considering the purchase of the HobbyCNC 4 Axis
Kit, however the one question I have is in regard to running a
4 axis board with only 3 motors.

If I purchase the 4 axis board and I only have a use for 3 axis at this
time, should I . . .

1.) Install components for all 4 axis and leave the 4th with no load
connected to the motor terminals? Would this harm / damage the board?
Does the board have ENABLE lines on each so that the 4th axis could be left
DISABLED until needed?

2.) Install components for 3 axis to start with and leave the 4th axis parts
locations open until I have a real NEED for the 4th axis?

The first option would be preferred, as it would lessen the chance of parts
being lost in the MESS I refer to as a shop.

If in the first option, it was required to hook a motor up to the 4th axis
TEMPORARILY for the purpose of testing and making adjustments,
I could live with that.

I built the HobbyCNC 4AUPC rev.2 four axis board with all components and simply am ignoring the 4th A axis till needed later. I set the 4th axis v-ref to the same value as the other three axis, but I don't think even that is necessary. This board worked first try and pushes my $10.00 Ebay motors along at 80ipm with little heating after hours of use. Happy camper here. :)

EACH axis independantly adjustable between .5 and 3A. Use 1, 2, 3, or all 4. EACH axis independantly adjustable for 1/2, 1/4, 1/8, and 1/16 step.

Your option 1.
Build the board up fully and simply don't connect anything to the 4th axis.
There will be no current draw so won't do any harm.
Just don't connect / disconnect motors with power supplied to board.

I have a brand new 4 axis HobbyCNC rev2 board for sale. Assembled never used for $80 if interested.

Rev level 2 is the latest and greatest version.

I am running the 4 axis board with three motors connected now on my CNC Model 2006, with the 200oz motors and power supply, the complete kit. Cutting at 80ipm. No problems at all with it, this is my second board, 1st one went with a cnc machine i sold.

Joe

Damn. I just bought my kit. Wish I read this forum earlier; that $80 assembled board is a good deal.

There are two very good alternatives to this board which use the same driver chips:

http://www.ohmikron.com/

and

http://www.cncresource.com/store/

These guys looked at the "state of the art" which used to be the HobbyCNC board (the 7062 chips are pretty new) and improved upon it in terms of form and function.

Also, read the posts concerning poor customer support and childish behavior by a certain vendor over at the Yahoo groups "CAD_CAM_EDM_DRO", "DIY-CNC" and then decide.

Note that until you buy a HobbyCNC board, you will simply not be granted access to the support group to look at the history of problems in order to make an informed decision about a purchase. You would be surprised how many people have to buy replacement SLA7062 chips from Dave at $15 each (lowered to $12 this week when I posted where they could be purchased for $8). Quite frankly, I believe more profit is (was)earned by the sale of replacement chips than by sales of complete boards.

The measure of a company is not how they provide service to those with no problems, but rather how they handle customers who do have difficulty, and here, HobbyCNC simply comes up short. Really short considering price gouging on spares.

Seriously, go with Ohmicron, CNCResource, Xylotex, Rutex or Gecko and spare yourself the headaches.

I have known Ballendo of CNCResource as an on-line "buddy" for a couple years now and he is a consummate professional who eagerly and freely helps out other hobbyists with advice, information and his time.

Phil from Ohmicron has built a website full of free information which will help you build a functional CNC system, plus he answers emails promptly and professionally. I really don't know him well, but so far, I have a very good feeling.

On the other hand, Dave only answers until he has your cash. Try emailing him with a support question and he won't answer except to say "go to the Yahoo group". But if you say something he doesn't like there, he'll kick you out and you're SOL for support. Just like the schoolboy who takes his ball and goes home if you don't let him win.

I take it you are not talking from experiance? and you have not put one of the HobbyCNC boards together. Well as far as Me i have gotten two boards from HobbyCNC and they worked out with no problems at all, If someone Blows a chip it is in my opinion their fault by not following the assembly instructions, you need to follow them and they are not hard at all. The instructions tells you in bold letters to check certain things before proceeding to the next step, and it also causions you about disconnecting things ie. motors while the power supply is on. which will blow a chip. To put it bluntly It is a Hobby Board hence the price, so if you do not follow instructions of course it will mess up on you. Like I said I have Two of them with no problems so for me that is the way to go if like most DIY'ers who want a machine for Hobby and some smaller industrial machines it forks just fine.

I've built two hobbycnc boards and have had no trouble. They're great! Just ask hobbycnc related support questions through the yahoo group Dave (the owner of hcnc) has setup and you're fine.

Your opinions are great, but both of you claim no problems, so you have no frame of reference to obtaining useful support from HobbyCNC.

By the way, when my board blew, I was one of two people that week who had entirely unexplained disasters when the only change made to boards which had been working fine for some time was to upgrade from 12v "testing" power supplies to 32v+ "operational" supplies. Vref checked, board working fine until then.

Quite frankly, during the time the board was working right, I had no qualms about Dave's service. I thought it was a great product. But once it blew, it became obvious I made a mistake in vendor selection.

Also note how many spare 7062s dave has been selling for $15 (just last week reduced to $12 when I posted a source that sells them for $8). It is clear he realizes there is a problem beyond what can be reasonably assigned to "user error" and instead of addressing and rectifying the problem, dave has decided instead to profiteer from it. Sort of like Ford not fixing the exploding gas tanks in Pintos.

Bukkowski, you can't get support from a group Dave kicks you out of for asking questions he doesn't like or is incapable of answering. Basically, dave has set a standard of support only for those who don't need it, or those who ask questions about problems he can blame the customer for. That isn't support, that's pathological.

I imagine you did reset the vref per powersupply. personally i use this forum for question more than the yahoo group, simply becasue yahoo groups are not as much to my liking. everyone is intitled to their opinion, and the yahoo group is privately maintained, so when i have questions i just email hobbycnc and wait for a responce, I would say if you want to use other boards go right ahead. but the number do speak for them self, and dave has sold alot of boards, so i would say the ratio of good working boards are way higher than blown chips and non working boards. For the money it is worth it to me.

Not that I know much about CNC Machines, I'm a beginner and hope to have a good machine one day. :) and hope to have more that just over 800 post on here.

http://www.ohmikron.com/ looks to me like a bad joke , the guy is paisting them on ebay ,nobodies buying , i emailed him asking how much to ship to canada he said that his shipping system hasn t been set up yet to calculate shipping to here ,anyone knows that it takes 1 minute to check the usps website , looks to me like the way that company works is if a guy bids 10 bucks and wins shipping is probably 100 bucks the box its in is 50 bucks the tape will be 125 bucks ,
come on im in Canada not China , i can throw a stone from my deck and hit washington state , and this clown can t tell me shipping costs

those guys are total fly by night clowns in my opinion

i dont have a hobbycnc , but obviously you haven t read the number of posts from many members who are quite happy with their setup

I had problems building two boards fromDave and not because the instructions were not clear or the boards were inferior, it was just because I was a dumba*s. Dave fell all over himself and went well beyond the call of duty to get me up and running and did not charge me a dime for fixing what was an obvious problem that I created. I have never received such service after the sale. I can't say enough good about the organization that Dave runs. Great product and he never gives up on you even when it is obvious that you are a moron like I was.

I have known Dave a long time. My Rickomatic mill (check out the photo section) still has and runs on an original Hobby CNC board and motors. When I first built the machine I had built the Maxnc driver board. The software and service were, to put it politely "Dog manure". I then found Dave's website and purchased his kit (at the time 50 bucks!) built it and had problems. I e-mailed him and he called me at work the following day! He was ready to ship me a ready to go board to replace mine! What service! The problem I found out later that day was my computer ground and not the boards fault. New computer and it's been running great ever since! I feel Dave has "tired" of all the people who just like to cause problems. Another problem in any application is trying to push the limits of the hardware. Sometimes that lets the "smoke" out also...I would just like to say that if it hadn't been for Dave, the Rickomatic might not have gotten finished and I would never have had the opportunity to do all of my "Cheap and Free" cnc talks! See ya at the cnc-workshop next week! Rick

here here, nice post, well as you can see one or two bad apples out of hundreds are pretty good odds to me for sure.

Ok,

I try not to get involved in this sort of thing, but I have to say I put a vote in for Dave. I brought a 4axis board from him. He shipped it to Australia, it arrived on my doorstep within 5 working days!!!

Oh it doesnt stop there. Becuse I am somtimes pritty stupid (but I can admit it, hint hint) I broke one of the current sense resisters. So, I emailed dave and then went for a surf to try and find some. Dave sent me the parts with out me even paying for them. I have just finnished setting up PayPal to pay him and that was 3 WEEKS AGO. Dave to his credit has not even emailed me once regarding the parts and postage over to AUS.

Service I cant fault. Sure the parts he sent me were cheap, but he didnt have to do that. Service is everything. I am a MCSE, CCNA, CCNP, CCDA and I have 15 years of working with everything desktops to server farms and when i find serive like that, I stay.

Now before I decided to buy his boards I looked around and sure I found people like you, (fancy posting a link to cheaper parts one HIS support forum, and has Dave DELETED that post, which I beleieve that he is inititled to?) but i found people like you to be in the VERY, VERY, VERY, VERY minor amount.

To be honest of the few people i found like you, most of them said, Dave dint do this, Dave didnt do that. After what i have read ALL OVER THIS FORUM I am pritty happy, that if my board does blow up, that it will be MY FAULT.

Please remeber that Dave does this as a hobby, sure it make some cash out of his hobby and I'll bet most to all of that goes into his time to design the boards and make them better. But havent we all started this with the idea of making money out of it in the back of our minds? I know i do.

Thanks Dave, if you are ever in Aus I'll buy you a beer!!! :cheers:

Fodder,

I realize many people are happy with their boards. My personal email however, suggests that a significant number are not satisfied but chose not to post publically because they don't want to have their online support terminated for daring to complain.

If I had received the type of support you describe, it wouldn't have been an issue. But HCNC just doesn't do that sort of thing so much any more. Occasionally, maybe.

From the email I have been receiving privately, it is clear many folks gave up and threw their boards in the closet and are now happy to hear they are not alone in their frustration. Many have decided not to deal with HCNC any more and are buying parts elsewhere to finish or repair their boards.

If an entire kit sells for $99, it's not being magnanomous to charge $67 for a new set of driver chips either, especially when Allegro wholesales them for under $4 each in reasonable quantities.

The fact that other hobbyist/businesses are selling the exact same chips for ~$8 (meaning HCNC charges 50% more) further demonstrates that customers who needed replacements for whatever reason were taking it in the tail end out of what is difficult to believe was anything but greed. One more chink in the "mister nice guy" costume. One more malfunctioning board in the closet.

By the way, one particular stepper drive designer who is clearly a head and shoulders above the rest (in orbit compared to some clowns in particular) actually did some design analysis of the SLA7062 implementation (which was posted on another site). Looks like the silk-screened 42vdc value is about 25% too high. As designed, if you're running over 32-34vdc, any medium-quick deceleration has a potential to blow up chips. With some modification, 34vdc can be made pretty safe. But no matter how you slice it, 42vdc is just too high.

From the above, it seems that many people who listened to HCNC advice and used higher voltage power supplies were fed information by HCNC which led directly to the damage of chips. Looks like reflowing the solder wouldn't have fixed or prevented the problems by any measure.

Sort of like when 1970s Ford Pintos blew up in crashes. Ford didn't do the five-dollar fix, though it would have solved the problem. Instead they tried to bury the issue and just said it was the customer's fault for getting in wrecks. They too got caught.

In any case, if you find you need the 7062 chips, go to www.cncresource.com. Theirs are about $8, and according to them, since I posted it on the HCNC site, they have been selling like gangbusters.

Looks like a lot of people who gave up out of frustration or lack of adequate support, and those who suffered in silence because they didn't want to be ridiculed for having problems (now known not to be their faults in many cases) are coming out of the woodwork to complete or fix their HCNC boards.

Any wonder why they are not patronizing the original vendor?

tintruder,

you oviously have some personal issues on this subject and/or personal relations with your as you put it friend with other site, so stop the baby whinning and go on your marry way, enough is enough.

IT IS TIME TO MOVE ON AND HAVE A NICE DAY ! ! ! !

And please don't start this "oh yea well your a ******" its just plain silly.
One of the reasons this whole site is liked so much by others is that it does not have the "nah nah nah I'm better than you are" and hopefully the admin will just simple close this thread and we can be done with it.

Joe

In order to be in business; anyone has to sell their products for MORE then what they bought them for. What fool would buy stuff and re/sell them for the exact price they paid for them? Seriously..... Its a cnc kit; competitively priced for the labor involved. There is nothing wrong with this.

I'm on of those who seldom post, just read a lot. But the responses to tintruder caused me to respond in his support.

Their is nothing he said that is not in my mind right on. His board shouldn't be run at 42vdc. If you did the voltage reflected back on the driver chips could easily blow them. I'm not sure why he charges so much for replacement chips, maybe thats something that might be better addressed on his support forum. Unfortunately this forum is limited to those who have purchased a board.

But in support of HCNC.

I have used 4 of HCNC board's and they are a great value.
Dave's support on his forum is good.
He listened's to what is said and has made extensive changes to his boards.
He repeatedly advises it is a hobby board and is not a commercial product.
The latest board I purchased had better routing of the grounds around the chips and better bypassing-- an indication he's addressing the blown chip problem.

I pesonally don't think he's getting rich selling the board's for as little as he does.

KissSys

I asked about the 42vdc. I was told its a bit much. And at that voltage; someone would have to build a frame w/ leadscrew or otherwise drivetrain & frame that would be able to handle that type of speed and torque. This structure exceeds the class of "hobby".

at 99 bucks aboard i dont beleave the man is getting rich from it, when you add up the cost of all the parts plus the board there isn t a huge profit margine , crying over the difference of a couple of dollars on a chip price is rediculous , he doesn t make the chips or act as an industrial distributor , so what if its 2 or three dollars more , DO YOU think it is worth getting up off your butt and running to the post office for a miserable couple of bucks , it cost a lot more money to make me move ill tell you that
we all want a good deal on a good product when we buy anything , but to cry over a couple of bucks dude you are in the wrong hobby

You can do as you wish with the fourth axis, populate it or not, it won't affect the operation of the other 3 nor will the components suffer any catastrophe should you decide to install and not use the fourth axis.

hi , i am intrested in buying it i am from india , what the best price can u offer , reply me immediately

I have a brand new 4 axis HobbyCNC rev2 board for sale. Assembled never used for $80 if interested.



Hi dizzy,
i am intrested to buy your board if are gonna sell , give me the best price
i am from india , probably i can use the board, based on your offer i will reply
i hope board works fine reply to the below mail

There is nothing wrong with the HobbyCNC board. It is low cost and works as advertised. The components are standard and the board is well made.

Dave can be a real prick, and he has been that way to many customers in the past. It's his way or the highway and that is is choice. It's his company.

If I ran either of my companies the way he run HobbyCNC, I'd be in the unemployment line.

I don't believe there is any need to flame ANYONE on here, degredation of someones name or business is unneccesary, and in this case it is not true :boxing: . I put in a query to Dave months ago about his board, and a possible application of such. He emailed me back, and was polite but firm, in his response. I have emailed him back a few times since then with questions, both simple and complex. His answers are always right on the mark, short and simple. He is not by any means rude or childish, such as someone who would come here and call him a prick. He has his way of running a business, which seems to work quite well, actually. Apparently, he has not pissed off that many people, for his products to sell like they have. I am going to take a stab in the dark, and assume that he was never out to get rich from the sale of SLA7062 chips, since he has now introduced a new board, that prevents the failure of driver chips, for all but the clumsiest of people. Hmmm... sounds like a good businessman to me. The customers spoke, he listened. He is constantly evolving his product to be bigger and better. Those of you who complain that his constant fix is to re-flow the solder to a non working component need to understand, if you don't already, that it might be his suggestion because of the knowledge of his product, and that some of his customers are not up on their PCB soldering skills. On a board that size, decent connections are everything. If you rushed the soldering job, you may have a bad connection. Either way, Dave and his business have (so far) stood the test of time. He, IMO, should not be looked at as rude or disrespectful, nor a poor businessman. He has gone head and shoulders above and beyond what I would ever expect. I don't have time to sit and yack with a tech on the computer or phone, and Dave doesn't have time to yaw on about my problem, you give him a question with decent info, he responds in a timely manner, with a short and simple response. I cannot speak highly enough of his service, and for that matter, his product. My advice is, if you are a hobbyist, buy his product. :) If you are looking for an industrial drive, look elsewhere. I did quite a bit of research before buying anything, and I feel like my money was quite well spent, in comparison to the competition, wherein the same general product was twice the price, at least, even though it is a great product as well. It boils down to this, I and hundreds of other people have had fantastic results, and a miniscule amount of problems once in a while, all of which Dave happily helps you out on. If something goes wrong with the board, it is not Dave's fault. Go look in the mirror so you can remember who assembled it. Sorry for the long post, just got me going on a good rant. I believe it is sad that the thoughts and opinions of a few sourpusses could offset the opinions of so many good legitimate customers. Anyway, back on topic, I suppose. (chair)

Dave treated me like I was an idiot with no technical ability. He did this in a public forum. And when he was called on it - he did it again. Doing so in public, right or wrong, makes him a prick in my book. When you are wrong, it makes you an ignorant prick.

Want me to publish the emails I got from his Forum Members after it happened? I don't think Dave does.

I am not a typical HobbyCNC builder. I bought the system because it is cheap and does the job. No need to try to re-invent the wheel. It takes essentially no skills to build, if you think you need to be skilled at soldering to build this board, then you are not skilled.

There is a history of an attitude problem at HobbyCNC, one that is "if Dave didn't think of it, it is wrong" That is fine. It is his business to run the way he wishes. He is the HobbyCNC master and Guru and the greatest electronics designer of all times.

BTW - Dave - I ran the 3 terminal regulator on the bench under the conditions that I stated for 2 weeks with a 1" x 2" heatsink and it never did "destroy itself" Never got above 125F - But then , that is what the data sheet said would happen. You might spend some time reading it. But then , you would have to understand what "Internal thermal overload protection" means

Have a nice day and I love your product.

No, it does not take any "skill" to solder this board. That is right. BUT, that fact alone does not keep some people away, some who don't know the difference between rosin core and lead or acid core solder.
And honestly, ****e happens. If you want to be justified in demanding "kiss my arse service", you shouldn't be purchasing a 79 or 99 dollar board. I believe there is a reason that Dave has no tech line. Honestly, if I had to have as much patience as Dave does, I would go out of my mind. I have seen some real no brainer questions on the support group, Dave has always been a real stand up kind of guy, and I believe that some people take his forwardness and bluntness as rude or uncaring. Just my 2 cents. I know I, as well as several hundred other people, are more than satisfied. Beyond that, you are right. He does business as he likes, and I find that more than acceptable. Beyond that, I don't believe there to be any point in repeating myself, or someone else. I will stand firm in my opinion of Dave, do or believe as you see fit.

Massajamesb,

I would suggest you take some time and read the posts. When did I ever demand "kiss my arse service"?

My board was up and running in less than an hour after I started it and it works perfectly? Why would I demand service?

My bone is that Dave treated me in a bad fashion on his forum and I darn well didn't like it. That is my problem and it happened. It's not some myth or story, it happened.

No one likes to be put down in public. Not a beginner or an expert.

Let's just let it go and move on, since we all agree that Dave makes a fine product. :)

On a board that size, decent connections are everything. If you rushed the soldering job, you may have a bad connection. Either way, Dave and his business have (so far) stood the test of time. He, IMO, should not be looked at as rude or disrespectful, nor a poor businessman. He has gone head and shoulders above and beyond what I would ever expect. I don't have time to sit and yack with a tech on the computer or phone, and Dave doesn't have time to yaw on about my problem, you give him a question with decent info, he responds in a timely manner, with a short and simple response. I cannot speak highly enough of his service, and for that matter, his product. My advice is, if you are a hobbyist, buy his product. :) If you are looking for an industrial drive, look elsewhere. I did quite a bit of research before buying anything, and I feel like my money was quite well spent, in comparison to the competition, wherein the same general product was twice the price, at least, even though it is a great product as well. It boils down to this, I and hundreds of other people have had fantastic results, and a miniscule amount of problems once in a while, all of which Dave happily helps you out on. If something goes wrong with the board, it is not Dave's fault. Go look in the mirror so you can remember who assembled it. Sorry for the long post, just got me going on a good rant. I believe it is sad that the thoughts and opinions of a few sourpusses could offset the opinions of so many good legitimate customers. Anyway, back on topic, I suppose. (chair)

I totally agree, I have had boards from him and all worked without a hitch. Just follow the instructions, Like cutting parts for your machine, measure twice cut once, READ twice and assemble once.

I just shake my head when it comes to a thread like this, Dave is going an excelent job in my opinion, An excelent board for the price, what more do you want?

I know in my designs on machines I waisted a heck of a lot more money on parts, and cutting parts, so others do not have to go through that, and Dave has done the same thing.

After opening my HobbyCNC kit, found out that a small capacitor was missing. Contated Dave Rigotti via email and had an answer in less than one hour. He offered to send me the capacitor. Have read in different forums that this is small problem with their packages but as far I am concerned, Dave is a profesional and takes very seriously his bussiness...
