    Just needs to be on.

    I finally had time to open up my machine and found the following:



    I presume to measure the voltage I use the GND and VMOT, is this what you would do?

    Edit: When I measure the voltage through the above mentioned terminals, I am reading 24 volts. This doesn't sound right.

    - Yes, that is correct.

    - Yes, this is also correct. Seems like your running a 24v setup, which is very nice because they tend to draw less amps. That will however make a lower voltage motor get real toasty for sure. You'll need a motor in like THIS (I don't know this seller; just using as reference).

    Edit: Make sure to use the GND that's next to the VMOT when measuring, not the one at the top.

    Would that be Nema 17 or 16?

    I am just trying to find one from a reliable retailer.

    Edit: Sorry I see it listed as Nema 17, I just cannot find a 24v stepper motor anywhere but eBay.com

    - I'm not certain of that, I think Geoff might have more experience for identifying the motor type. I'm more of a circuit board expert.
