Hi,
I'am a new to reprap and I have a problem that I hope sameone can solve.
I'm using a Marling on e prusa using Megatronics Board.
I set the Steps per mm in the following way:
#define DEFAULT_AXIS_STEPS_PER_UNIT {80, 80, 200*16/1.25, 760*1.1} // default steps per unit for Prusa
When I print a square the X axis is correct but Y axis is longer by 10%.
The belt are tightened, I use the same alloy pulley, I dont use EPROM, the stepper motor work well and do not lose any steps, I tried to invert pololu X e Y with the same result...
Why this?
