Re: Encloser fan control

I'd recommend a 120v fan over a 12v fan any day and have it run all the time. Why wait until things get hot? Be sure to mount it so it blows air into the enclosure at the bottom somewhere and have a simple grill/vent at the top somewhere. Don't have any enclosure fan positioned to suck air out as th...

Re: First build. Old equipment + new technology= FUN???

Yes, as Keith stated be sure to set your steps/rev the same in Acorn and on the drive with 1600 minimum. Then calculate your overall turns ratio. You have to do this first. You cant set any travel limits or soft limits or any other limits until the machine movement is accurate.

Re: Axis Setup Issues

I'm not sure yet that why I ask that you start with a fresh install of 4.80, so that we are all working with the same version, and with ZERO modifications to the Acorn or its settings so that we can work through it together. We cant possibly know what you've done or wired right or wrong. Starting fr...

Re: Axis Setup Issues

As noted please take the time to update your software to the current version, 4.80. Centroid does not support old versions of the software. Also, post a link to the drive manual so we can see the wiring diagrams and confirm how you have the DB25 configured. I would start with wiring ONE axis of that...

Re: Axis Setup Issues

Also, what drives do you have and what diagram did you follow. Post pics of the drive wiring and close up so we can see details. There shouldn’t have been a reason to remap pins if you are wiring to individual stepper drives since you just end up with bare wires on your DB25 cable. Did you double ch...

Re: Converting Chinese CNC Router from XHC Mach3 Motion Controller

Glad to hear it. I've updated the plasma to 4.80 and found a bug in the plasma restart feature when using the job repeat function. Centroid sent me a work around and they are working on a fix now. My newest router retrofit is on 4.80 and works flawlessly and my other router still need to be upgraded...

Re: New Acorn User with questions

Hi Brian and welcome. Those drives are 5v logic and will only wire to the DB25. The headers are for servo drives and a very select few hybrid stepper drives. You can order the breakout board on Amazon for about $8. Follow schematic S14976 found here: https://www.centroidcnc.com/dealersupport/schemat...

Re: Will the software let me jog the machine past the limit switches when setup?

Post a current report so we can see the settings. Mechanical switches or proximity switches? How are they wired? I can jog my latest router with proximity switches wired in series to a single input at max speed (650 IPM) towards either end of the table and it stops every time. Just as you stated, it...
