A little late but I built a Router Table from Joe's eDrawings back in march. It turned out so well that my son wanted one also so I built another one of them. We are having so much fun with them that I mised the summer season all together, or was there no summer this year?:) Been working on utililty drawers for it and a rack of 14 tools with automatic tool changer. This is working out real good.

I wan't to thank Joe for his time and generosity of his design.

Here are some photos of the build. I will post more photos (the drawers and changer etc) later.

Great machine!

I'm very interested in your toolchanger, looks like it mounts on the router? Is that correct?

You could zip your video up, & just post here as a zipped file.

Nice work!

Video short clip:

The Quick change tool holder was patterned after
http://www.hightechsystemsllc.com/index_files/Page1446.htm
I have one of these for my Mini Mill but they didn't have one for a 1/2" so I just made one out of AL with a 1/2" shaft to fit the router.

They only had 5 sizes of tool holders so I had to make them also.

The tool rack was made with the router out of corian.

JLT,

I really like that ATC.

I was looking at the site you posted http://www.hightechsystemsllc.com/index.htm , I understand how the tool (endmill, etc...) keeps from slipping in the holders, with a small set screw.

How does the holder keep from slipping (rotating), in the actual toolchanger? The toolchanger does not look like it would provide enough clamping preasure to keep the tool holder from slipping, I don't see any type of flat on the toolholder to give a positive stop. I may be wrong, I'm just really interested in that product (toolchanger).

It looks like you have a great setup going on in that video!

Any chance of a longer video, with some cutting and maybe a couple of toolchanges?

Also did you see the "Drill Chuck Holder" they have? http://www.hightechsystemsllc.com/index_files/Page513.htm

Thanks for sharing your cool project. :)

Wow I'm blown away. Your router looks cool and colossal in some of the pics. The automatic tool changer & video is extremely impressive. Joe should be thrilled when he sees it. One question, I'm assuming when you change tools in production, for two different kinds of cuts you would include that in the gcode. Assuming that it's running, makes it's passes, pulls back to the tool dock and shuts off before or during. But how does your router know when the spindle on your hitachi has fully stopped before it can release that bit and grab a new one or do you just set a certain amount of time? Thanks!

Can't help wondering how the red part and spring handles 30,000 rpm and the fact that the tool is extended a long way from the collet.

Have you accidently run the gantry into a drawer yet :)

How fast have you spun that tool changer. Seems a little large for 20,000+ rpm.

David Da Costa
12-11-2006, 02:32 PM
I have been in communication with Derick at High Tech Systems and he confirms some of the possible dangers at spinning at such high speeds.

Here is what he says.

"The rapid changer is only guaranteed to 10,000rpm. The spring will will possibly come off after that speed. I have some heavy duty
springs that increase the pressure and should be able to hold up to the higher RPMs and horsepower. I have a 1/2" adapter for the Taig that screws on. You will need to take all responsibility for safety. I recommend a Plexiglass shield around the router in case something goes wrong.

I have been working on a ATC for the Rapid Changer for awhile now. I need to finish machining parts to see if it will work or need design changes. Goals have been durable, affordable, simple to use and require no outside electronics or air. I haven't reached all the goals yet."


His ATC that he is working on sounds very interesting.

I do most cutting at around 8000 RPM. I have spun it up to check for vibration but for me cutting at hi RPM's just burns up bits.

Thanks a load for sharing this. As Joe says, this one is going to be a hit and I can just see High Tech Systems falling foul of good publicity and having difficulty supplying demand. Hope not, my order will be in as soon as I can get it there. First I must see if they can make metric versions.

How do you set up the tool changer system in mach 3? That is the part I have yet to figure out.

DayneInfo
12-12-2006, 10:57 PM
silver4dracs - I have been looking at the Mach website trying to figure out how to implement tool changer. Here is what I think you have to do...in a nut shell. Config-General config you set the tool changer option to Auto tool changer. This is what Mach manual says:

Tool change: An M6 tool change request can be ignored or used to call the M6 macros (q.v.). If Auto Tool Changer is checked then the M6Start/M6End macros will be called but Cycle Start does not need to be pressed at any stage.
Figure 5.21 - Logic Configuration dialog

So it seems that you have to write a macro in VBA....I think. If you click on Operator then VB Script Editor, open file, navigate to Mach3 folder then to Macros. You will find an empty M6/start and end. I am assuming you would edit them to write you tool change macro. When a tool change is called for it would then run the macro and use it to select tool. There is also an area to store tool information such as diameter and tool number. Not sure if any of this would have to be filled out or not. I am going to continue to look but am no where ready for this to be used yet.

Dwayne

DayneInfo
12-12-2006, 11:08 PM
Heres a little more.

10.8.3 Tool change - M6 Provided tool change requests are not to be ignored (as defined in Configure>Logic), Mach3 will call a macro (q.v) M6Start when the command is encountered. It will then wait for Cycle Start to be pressed, execute the macro M6End and continue running the part program. You can provide Visual Basic code in the macros to operate your own mechanical tool changer and to move the axes to a convenient location to tool changing if you wish. If tool change requests are set to be ignored (in Configure>Logic) then M6 has no effect.

joecnc2006
12-12-2006, 11:26 PM
I believe as he stated in post #9 that he just adds the text manualy toi the g-code for the proper x,y, and z movement, this can be done when using the home switches to make sure the machine is always in the proper place at startup.

I haven't looked at it, but there is a tool change macro video on the www.machsupport.com site, as well as some sample tool change code. You need to write the code in the M6 macro using VB script. The code will need to determine the current tool, and probably contain all the offset information for the tool locations. You also would enter all the tool information into the tool table, and use H43 tool length offsets when changing tools to keep the z axis at the correct depth.

He uses the software to turn on and off the router prior to any tool changing, if you look you will see it stop and then start just before cutting.

Thats it, spring presure holds it from rotating in the chuck.
There are 3 tapers invalved.


A Set screw in the holder holds the bit from rotating.

Hi Guys

This Tool Changer project is very interesting. As with a few other people, I am still wondering how much HP this HTS Tool Changer can handle? Obviously when the red sleeve is released the six steel balls pulls the Tool Holder up into the RTC. Because the Taper on the RTC is the same as the Taper of the Tool Holders, this is what prevents the Tool Holder from slipping in the RTC. I have been looking at the HTS Tool Changer System with the idea of possibly using it on a Tool Changer for my 2 HP CNC Milling Machine. One of my concerns with using the present setup, is if it is strong enough to handle the higher HP and RPM’s? I sent an Email to Derek asking him this question and also what the HP Rating was for the present HTS System and here is part of his reply:

“I am coming out with a 15hp version that will work with collets. These will hold the higher horsepower and torque. Should have something by the 1st of the year if everything works out”

He didn’t actually tell me how much Horse Power the present HTS System can handle, but from his response I gather that it was not designed for a 2 HP Spindle. I believe the present setup works fine with a Sherline Mill or equivalent. My concern is using this system with these higher outputs of a Router? Please be careful using the present HTS Tool System with a router setup. To high a speed or to much load and there are going to be allot of metal parts flying around the room. For my application, I am looking forward to the higher HP System that should be out at the first of the year.

JLT,

I have been thinking of nothing else for days, ever since my attention was drawn to your video on the Mach list. Before I launch into a couple of questions; my admiration for your invention is profound, and for me the beauty is in the simplicity. All over the world there are guys saying, I can do that, and scrambling to copy you.

I see you define yourself as a hobbyist, but can I suggest you name the device? The JLT auto changer doesn't quite cut it, but if the T stood for say, Thompson, the Thompson Tool Tray has a ring about it and it might well catch on. Any family name starting with T should work, alliteration has a way of sticking with people. Its not money, but fame in small parts can be rewarding.

The questions I had are, is there anything different to the High Tech Systems device about the rapid changer you made, other than dimensions..? I would like to buy their system as I do not have the skills or time to make it, plus I have bought gear from them and it is lovely kit.

Secondly, you mentioned you used Sheetcam to drive the tool changer, did you just program moves that mimicked drilling and cutting moves in that specific location? If so, how did you get the machine to locate the tools, did you put the work in a specific location, or did you use a combination of Machs machine coordinates and home switches to find them?

Best Wishes

Hi Chris,


The only modefication to the High Tech Systems Rapid Changer was the mounting shaft to fit the router 1/2" . They have that option now.


I don't use Mach but I'm sure the same thing that I do could be implemented with it.

TurboCNC stores all tool length offsets so you don't put tool length offsets in Sheetcam.

I do all cutting in Fixture 1 (G54).

Home all axes with no tool (T0) and no Fixture (G53) at the start of the day or week:)

All tool changes are done with no Fixture (G53).

Set your work starting ref. when in G54 and reverence tool (T0) in the chuck and TurboCNC set for T0.

You should look at making money from your idea. Maybe a Dummies Guide to ATC or production of the product. Personally I would have no problem paying $100 for complete how to manual. As a newbie to CNC I would be the perfect proof reader.
I am in final stages of my mill to do wood columns up to 24" by 12' and already have people asking me to build them a machine. see http://turningaround.org/4_axis_mill.htm . I realy don't want to get in the machine business and am looking for someone to work with as a consultant. What can I do to encourage you in your endevor? Be glad to add section on my web site , www.turningaround.org , if you want. Also a great way for me to learn more about your briliant idea.

Hi,
I've been enjoying all this, but the videos aren't there anymore.
Is there a new place(location where these can be viewed?
I saw one that depicted the machine routing a sign and returning to change tools but can't find it anymore.

Help anyone?

Hi David,
Nice site! I've been watching you too as you progress.
Will you be building the auto tool changer rack using the Hightech "rapid changer"? I'm wondering where those videos went...?

I just ordered the changer system and am planning to set up a rack for tool holding/changing.

Thanks,
John (bloy)

I would like to have an ATC, but I am a little concerned about the safety of the HighTech current offering running at speeds well above it's design parameters (it's great on my Sherline).

HighTech are working on an ATC solution for for higher speeds so I shall probably wait and see what they come out with.

Bloy2004
12-31-2006, 11:41 AM
yes, that is my concern too (the higher speeds), but Derek, at High tech has the heavy spring which will work for my router since it is variable speed and can function well in the 8Krpm to 11krpm range.
One thing I have found is that changing tools manually is SOoooo inconvenient! :

before I go asking questions let me tell you this is an absolutely FAN-BLOODY-TASTIC idea, I know it's been said before but again WELL DONE, you are a pure genius..

could you tell me from the bottom of the collet nut on the router to the bottom of the quick tool changer what is this length, also could you instead of using a grub screw to hold the tool, could the bottom ring (the ring that sit below the GROUND-CIRCLIP) Be somehow converted to screw down onto a collet to fix a tool in place, thus ensuring greater accuracy(less runout) and higher torque(souldn't rotate)

ALso how did you get the dust skirt to raise and lower ??/

I can tell you that the 1/4" bits fit very, very snug into the Holders, and I can not tell of any runout effect on my cuts.

Do mind telling us what modifications you made to the tool-changer for use with your router, apart from the 1/2" shaft?

Also, you said earlier that you had to make some of your own tool-holders. I am interested in this tool-changer, but all my tools are metric - did you cut your own tool holders from bar-stock, or did you just bore out genuine toolholders to your required diameters?

Cheers.

I made one of the tool changers out of uhmw.....I used the heavier spring as well but it came up around the snap ring and spun apart...I bought another spring and changed the snap ring to an eclip.....I took .015 off the dia of the retension knob it shortened the travel enough for the holder to come out....I also wrote a tool change macro for it and modified my post processer to add the g43 for the tool lenght offsets

you will need a variable speed to slow it down, the spring which engages the tool holder is not stiff enough for that RPM, and if you put a stringer spring it in to will take to much to lift the cover to make the ATC work.

I was thinking about setting it up so that the cnc machine made the change, not me by hand. I guess I could get a router speed controller and slow down that way.

Glidergider
02-22-2007, 11:57 PM
The mention of a router speed controller has me wondering. How does the DIY'r control router rpms? I imagine that most of the DIY'r controls it manually, but I don't know that or sure. That's how I intend to operate soon. This discussion about tool changers definately begs the need for a speed control hooked the Mach3. How many of you guys control speeds with the CNC program?

If I missed this discussion in a previous post, my apologies.

A little late but I built a Router Table from Joe's eDrawings back in march. It turned out so well that my son wanted one also so I built another one of them. We are having so much fun with them that I mised the summer season all together, or was there no summer this year?:) Been working on utililty drawers for it and a rack of 14 tools with automatic tool changer. This is working out real good.

I wan't to thank Joe for his time and generosity of his design.

ger21
03-04-2007, 02:01 PM
Yes, it's for Mach3. The numbers in the macro correspond to the location of the tools in the tool holder. You'd need these numbers to correspond to your setup. If your using inches, put the numbers in the macro in inches.

I tried to buy a tool changer from Derek, actually M20000, but unfortunately the payment could be done only by PayPal or money orders. Here in Romania I have no access to PayPal, it is not in their portofolio, and money order can be done only by Western Union about which here are only bad words, and is VERY expensive. Asked Derek severla times about wire transfer which I can do but he did not reply ever. So, is here somebody who tried to build himself such a tool holder? If yes, can help me to build one for myself. I do not have a lathe or mill but I have a friend who is working in a workshop. Could someone help? maybe only with a sketch and few dimension. JTL, I have sent you a PM, did you get it? Could you please, send me the plans of docking area for tool changer? My address is vlaroliz@gmail.com.

Thank you,

Zoltan

They might do a wire transfer. The problem with western union is that there is so much illegal stuff going on, so many American companies are afraid to mess with anything else than PayPal. Even with PayPal however there are problems.

So is this macro for MACH 3? I'm in the process of setting this up. It appears that you are using metric measurements. Can this be set up for USA measurements?



Here is the Macro I use. The tool numbers start at 1 on the Y24" side of the table.

do you have the plans for the toolchanger? If so could you send them to me? I've got the autocad file for the corian cutout for the top but nothing else.. thanks!:rainfro: also how does the tc work out at higher speeds? I thought it was only rated to 10k RPMS?

The plans for the tool rack (top and bottom) are on the thread somewhere Ill have to look.


Yes, 10k but I have no problem with the heavy spring going to 12000. Haven't really tested the limit yet.

I don't have the plans for the Rapid Tool Changer.

I'm trying to find out what size and variety of endmills you used to cut the MDF parts for your project. Can you help?

Help could someone please answer this question so I can start building. What size bit are you using to cut out the MDF parts.

What did you use for the small metal clips that are shown in the photos? Also, in one of the videos I saw of your ATC it appears that there is some sort of door or covering that closes over the tools in the holder when the router moves away. Is that your design and if so do you have the plans for that as well?

Thanks,
Greg

The E-clip is 1.442" OD and .75" ID. Thickness is .055". Must be ground to fit tool holder groove.

The door is just cardboard swinging on the 1/4" all thread. This was just a temporary thing till I got my floating dust brush.

Another Harbor Freight Junkie!!! I go there all the time. I don't see that size though in that assortment. Oh well, I'll find them. Where abouts do you live? I'm out here in California, for the time being and then will be moving back to Missouri.

I really like your dust door, it would make sure that chips don't get down into the tool holders. By the way, did you make your own tool holders?

Thanks for your reply, and the inspiration.

Howdy JLT,

Love the ATC. Going to have to make one when I get mine running and figure out how to use it . but in the mean time I alrady have Duct collector so I am wondering if you have plans availible for your Floating brush assembly? . I know you aquired the brush from a unknowing doner ;) . Hope you didn't get in to much trouble :D . I will keep eye my open for something maybe i can use. thanks. for al the great ideas Kent

Thanks Switcher. I got it and I bought it. They are one cool and simple piece of engineering. I found the "E" clips today at a place I least expected, a company here in town called Blue Collar Supply. They have a big bin of them at 10 cents each and I bought 5. Wasn't really sure they would work but they are going to be fine. They are a little bit bigger than what JTL had used. My buddy here just sold his CNC machine so I'll have to find another way to mill out the tool holder. I wish I had the "G" code so I could just load up and run it in MACH3.

By the way, where is JTL?

While my dust collector is still being prototyped and needs to still be tested once the machine is up and running. I took the idea for JLT's machine and drew it (I could not find his plans). If you are interested I can supply the drawing file for the parts (realizing that I have not tested it yet). At present it will raise and lower with very little effort but it does require modified sides from what Joe's design calls for. You can see it at www.cncmachine.phillipsfamily.ca (http://www.cncmachine.phillipsfamily.ca)

Has anyone checked the run out after putting this on there spindle? Seems like alot of distance from the collet on the router. And store bought routers are know to have run out to start with. and the longer your put the tool out there the more runout you get. I am just wondering what kind of run out you are looking at after doing this mod. All the store bought routers I used had almost 0.005" run out from the factory and if you extended that out to say 2" from the collet nut it was more like 0.02"

Yes, i have this issue, just barely with the old style, but the new style has more and makes my new machine shake somewhat, you can read about it in my new 4x4 machine. Dereck is working on the issue now.

Its more of a issue with the spindle I would think. If you could regrind the spindle taper true then it would be possable to make something like this work. Bu then you half to have accurate made collets. But store bought routers are just not made to have bits in them that extend out 2-3" from the collet nut.

Working on building a tool changer a couple of questions I have:

1 - In the M6Start.m1s code I see the code to turn cutter length compensation on with:
Code "G43 H" & NewTool ' Set cutter compensation on for new tool
but I don't see anything turning it off when you come into the tool change process. I would think you would want if off as you always want the change to occur at the same location and compensation would alter this for each tool (assuming you enter something different than 0 for tool length compensation).
Am I missing something as to why others have not used G49 to Turn it off? Or should this be added to the code?

2 - the brushes for the floating dust collector, what diameter bristles are people finding work well? Trying to figure out what is stiff enough to keep it up and yet soft enough to move nicely around things. I am assuming the brush material is nylon as well.

Thanks for your help.

Hi,
I went to the http://www.hightechsystemsllc.com/index.htm and saw that there are only two sizes of the old style collets available (3/16 and 1/2).
What is happening? I wanted to order more 1/4 collets for the ATC that I am slowly working on. Are these being phased out? Can they be special ordered? A year ago I got the quick change unit with an assortment (5, one of each) of the old style collets. Since I use mostly 1/4 shank tools, this presents a problem.

Any answers to this?

Thanks,
John

joecnc2006
08-13-2007, 08:28 AM
The Quickchange unit is the same you can use the new holders in your unit, with the dempels at the top it is a better design.

You can always e-mail Derek and he will help you he is a very good guy to deal with, he will tell you straightup with all his products.

Joe

Thanks Joe,
I'll see what Derek can do for me. I can't really afford to get the newer ER collet system..and the added extension is too much for my use. Hope he can still supply the older styles.

Thanks again,
John

Great Work!

A friend and I are planning on building the Joe! We have a professional grade CNC available, so all parts will be able to be cut out....but considering all the parts are cut on the CNC, what would you say the difficulty is of this build?

Thanks,
Spencer

Well, say all the parts have been made perfectly..... How difficult is it to assmble it, attach the motors, insure that it is square/level, etc.?

And did you run in to any problems?

bp092
10-16-2007, 09:32 PM
It's not hard. Put it this way, I knew nothing of CNC routers when I embarked on joe's 06 model. You learn as you go; other than that it's pretty easy. There is a wealth, a complete wealth of info here at the zone in joe's dedicated forum on how to build this machine. A few dozen people here have build logs, filled with photos and info. If you sit down, plan, order the right parts and follow the steps correctly you will have a solid DIY machine. It only requires basic woodworking and metalworking skills. I think the hardest thing on the machine if anything is milling the bearing angle slides and gluing the torsion boxes together.

Mine is collecting dust because I don't have a CNC machine to attach it to. I have read where people have run them up to 20K RPM. He is using a higher strength spring now.

What kind of router are you running? What all do you have and how much?

Buzz9075
01-14-2008, 08:26 AM
Not sure what I want.... I have many adaptors, the drill bit adaptor with head. I will gather all the information in tonight and post. Here is a list of the issues I have had (with the stronger spring).
Dust collects between the head and the adaptors, making if very hard to remove the adaptor till you get the dust out.
Even at 10K to 12K (as many have proved you can run), the adaptors will spin in the head unit when a high strees zone is hit (really obvious in oak with the grain gets tight). This cause a side effect of removing the finish of the cutters.
For some reason I can not longer get the V cutters to spin true when using it true
Noise level from the router is much higher with the attachment in versus out. My house is much quiter running the router without it in.
