400 Step Motor Conversion for MK2
I have changed the stepper motors on the X and Y axes of my new MK2 kit to higher resolution 400 step per revolution stepper motors instead of the stock 200 step per revolution. In my mind this will yield the same result as having even higher resolution microsteps in the motor drivers, which I cannot change.
Now I'm trying to find the changes I need to make in the firmware. I've Googled the subject and found references to several define statements in the Marlin software. I've searched the Arduino files I downloaded from the Prusa support page for those defines and several others that I thought of, but I've found nothing.
Does anybody know what I need to change in the firmware files to convert to 400 step/revolution (0.9 degree/step) stepper motors? Thanks.

Double the values at x and y :
M92 X100.00 Y100.00 Z400.00 E161.30
and write it to the EEPROM (M500).
OK, after an new firmware upgrade always you have to do this, but anyway, you do an PID also after an upgrade.

Thank you!
Re: 400 Step Motor Conversion for MK2
maybe you need to retrieve the values from the eeprom once (M501) after you compiled the firmware witht he new values. or just sent a M92 X200.00 Y200.00 to the printer.
