Firmware changes for generic motors
Hi, I recently bought a MK2S to MK3 upgrade with the intention of sourcin my own motors. The motors that I have chosen for the job have the following specs:
Step Angle (degrees) : 0.9
2-Phase
Rated Voltage: 3V
Rated Current: 1.7A/Phase
5mm Diameter Drive Shaft
Holding Torque: 48N.cm
NEMA 17
I know that for this to work I will need to make changes to the firmware, however, I was looking in the configuration.h file of the Prusa MK3 firmware and wasn't able to find where to change the steps per mm of every axis and where to control the amount of current the stepper drivers send to the motors.
Does anyone have any experience with this?
Thanks,

First you have to adjust steps inside firmware and tune the lenght. About current you can try the current defines and test if they overheat or not.
Stock motors are more than OK, for XYZ you will not take much benefit from a 0.9º motor
