    - Measuring the voltage will vary depending on what type of board you have and how the driver input power is sent. The place you need to measure the voltage is at the "Driver Power" source; see image below for an example.

    Thank you for the information! Do I have to measure the voltage while the motor is running? Or can I just have the machine 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.
