Re: Stepper Motors from old Laser Printers

Thanks amigob,

looks like that puts me on the right way
i've now set those values and the motor starts to rotate as it should be

#define DEFAULT_AXIS_STEPS_PER_UNIT {80,80,4000,500}
#define DEFAULT_MAX_FEEDRATE {100, 100, 5, 25}
#define DEFAULT_MAX_ACCELERATION {500,500,100,2500}

#define DEFAULT_ACCELERATION 500
#define DEFAULT_RETRACT_ACCELERATION 500
#define DEFAULT_TRAVEL_ACCELERATION 500

at first attempt it's rotating extremely fast with this settings, like going from 0 to 40cm in under 2seconds and produces extreme torque...

then i put back in the jumpers for Microsteps and that's it!!!
Problem solved, motor runs smoothly. Now I can solder all remaining motor cables, assemble everything and tweak the Steps per mm.

Thank you very much for your help!
