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.

Tried the override sequence without any luck - set the Parms, set level 3, went back to the home screen - showed F10 Here grayed out - pressed it and it turned green. Screen never stopped showing the...

I agree that is a major accomplishment - and I understand why it is a "package" - in the DOS world so may drivers are chip set and software specific. I have done a little research on doing this and...

Thanks for the info Bob - out of my price range as a hobbyist but certainly can't speak for shops. The guy I bought this machine from probably would have been interested since he really like the...

Definately interesting to me - I have one of the usb floppy replacements like you describe - have not even tried installing it until I get the machine running mechanically. My old Ajax mill had a...

Here is the report from tonight - had a crash Monday night (really stupid setup mistake on my part!) so decided to take a day away from it and start back tonight. Things ran good tonight. Dan

A little late on this one but I use Fusion 360 for my hobby work. I started using it since it is free and looked pretty powerful. There is a bit of learning curve, but overall I think it is worth it....
