This machine is a hobby project and I basically took a year off from playing with it to build a new shop. Shop is done and machine is in it's new nice heated and air conditioned home so I decided to...
Thanks - I was thinking this might be a simple matter of me not doing something that I should have been doing so I didn't want to bother Bob. I ended up calling him and he got the problem sorted out...
Just got this machine running and trying to home the machine. I power the machine on, hit the reset button to power the drives, then select Home and hit the cycle start button but nothing happens -...
Finally back working on this machine again. Got the Z axis up and running (both the z and y need more tuning) after replacing the servo motor. So now that things all move, I thought I'd try homing...
Actually, I have not had any more trouble with the controller since putting the lamp in the cabinet - I also added fan in the shop that runs all the time to keep the air moving - so far so good - the...
Last weekend I had some parts that I needed to run - the mill did it's usual stunt - start the program and anywhere from a minute or two into the run the spindle would just shut off - hit the feed...
I upgraded the motherboard and went to the latest software revision a couple years ago. Only difference is that I kept the Compact Flash card. I did manage to clone the compact flash card to a...
Thanks for pointing that out - I had not looked that closely at it yet. Still gathering information at this point. I did sent a message to Centroid but no reply yet (beyond the one from cncsnw). I've...
Thanks for the information - that will help a lot.
Finally looking at replacing the Linux based Servo3IO and CPU10 DC servo drive in my Ajax DM45NC mill with something like the Acorn. I looked at other controls but am pretty comfortable with the...
Yes! I got it off ebay thinking I would use it for a future project but have it stashed away. If you have any info on it I would love to have it.
Ok - tried to check this out and had some luck. I will make sure I have a printed copy with me next time and see if I can get better results, but so far I think the encoder may be flakey - want to...
I may be running it again this afternoon (if I can get to my shop! I has been raining all night and all morning - may have to swim!). I ran it yesterday for a couple hours and could see about a .005...
Control is Centroid Servo3IO DC running SEMS MTS30U4-57 brush type DC servo with brake on the Z axis (factory setup - this is an Ajax DM45 NC mill). I do have some backlash in the Z axis - was...
That helps - I hope to install some sort of limit switches in the future so the homing should get better - this is an Ajax cnc mill, factory installed cnc control. It had homing marks on the x and z...
I am a hobbyist and use this mill for hobby uses so it seldom gets ran for long periods of time - I made 9 parts Sunday that take about 30 minutes each to run. At the end, I noticed that the last...
I am running a CNC mill that has no limit or homing switches - the control board is the Servo3IO. I see it has terminals for limit switches but I have not yet figured out how to mount switches on...
Got the 4 FET's replaced - glad I have a decent desoldering setup. Looks like I'm back in business.
Thanks! that looks like the information I needed!
I have a mill with the Linux version of the Centroid control. It has a 4th axis driver board on top of the Servo3IO board. I need to disconnect and permanently remove this board. It has 4 fiber optic...
I have an Ajax CNC mill with a Centroid all in dc control (Linux version). Hit the end of travel on the X axis today and suddenly the X axis is dead - will not jog - nothing. Started digging and...
Been away from this project for quite some time but finally worked on it Saturday. I was able to get the Y axis servo up and running. Had to swap the phasing of the Hall sensor wires to get the motor...
Bob - can the SD card be swapped hot or does it require power off when the card is inserted or changed?
I have been using Fusion 360 for a couple years - both at work (paid subscription) and at home (hobby). I have a partner 1 but it is not up and running yet - using the fusion 360 with a different...
As the title says, I'm looking for information on a CNC USB board that was sold by buildyourcnc.com. I contacted them and they said it was built using the DIY info in the PlanetCNC web site and they...
I agree - here is a sketch showing the dimensions of the ER 11 collet. Hopefully you have a set of digital calipers that you measure your collets with and see what the dimensions are. If you don't...
Tore into the control panel and found 4 switches that were not making contact every time they were pressed. Has some used switches so I replaced those and things work a lot better now. Have the x...
I'm going to throw a couple things out here - first, if your collet stays in the spindle cap when when you unscrew it, I'm going to guess that you have an ER type collet. Most of the 800 watt...
I finally got the override to load and used it to check the Y axis - motor spun but errored or with excess following error instantly - thinking that may be telling me its turning the wrong way so I...
RL49 - thanks for the information and the reference to where it is found - I was able to find a copy of the manual to download from the Milltronics website.
