Hello,

I have a custom plotter that is really like a CNC machine but with a custom pen holder.

In my current design I have an X and Y motor but I will be switching to a more traditional design with two Y motors and one X motor

Therefore I need an additional stepper motor. My current motors are oyostepper motors, High Torque NEMA 17 Stepper Motors for 3D Printers (https://www.oyostepper.com/category-6-b0-Nema-17-Stepper-Motor.html)

They are rated at 0.4A but have reasonable torque. I am having a hard time finding a matching motor - most seem to be rated at a higher current, like 1.68A.

The question is - can I mix motors of different ratings? Currently I am using a bench power supply with 12V and 0.4A.

Or should I replace the existing motors and use a matched set of three motors?

Thanks.
