M31 Motion Controller / Re: M 31 stepper wiring
« Last post by Tweakie.CNC on February 13, 2026, 12:54:33 AM »Hi Ed,
Perhaps I am misunderstanding your comments but you cannot connect stepper motors directly to the M31.
The M31 is a ‘Motion Controller’ in exactly the same way that the Warp9, ESS is a ‘Motion Controller’ – they each require drivers (such as the G540) to operate the motors.

Wire colors are superficial and thus tend to mean nothing. There is somewhat of a standard, but those standards can change from person to person or company to company. This makes going off of wire color VERY unreliable.
What Drives do you have?
thanks,
Paul

that is my problem , the manual does not state that ( blue to ? red to ? etc) Also vfd wiring .

The details for connection of the M31 to your motor drives are here:
https://support.machmotion.com/books/motion-controllers/page/m31-motion-control-setup-manual
If you are still using the Gecko G540 for your motor drives then you will also need a suitable cable etc. to connect the M31 screw terminals to the G540 parallel port DB25 connector.
The Gecko G540 manual is here;

Hope this helps,
Tweakie.

« Last post by paul.stephens on February 11, 2026, 01:15:16 PM »Hi Ed,
The wiring for the M31 will depend on your drives common.
If your drive common is 24v then you will need to wire to S- D-.
If your drive common is 0v then you will need to wire to S+ D+.
I believe most drives are typically NPN so the drive common would be 0v, but that is Not all drives.. I would highly recommends checking the manual on your Motor Drives to determine what your wiring needs to be.
thanks,
Paul

Wires, red green blue white , where do they mount on the m 31 ( s+ s- etc ) . Also need wire diagram to vfd Chinese , have contacted support but no reply yet .

« Last post by momofr83 on February 10, 2026, 05:07:24 AM »No it doesn't, thats why I built this software. It allows to use M67. I just added S for non mach users.
I can now engrave within Mach4.
I still use S for cutting only.

Last I tried it failed miserably.
