I am having trouble with my x-axis in Pronterface. It moves fine when given commands to go any specific distance, but when told to home, it does not move and instead begins a high-pitched whine. The whine stops when I manually press the mechanical endstop.
I have tried adjusting the Pololu A4988 driver but it does not change the whine. The other axises work fine. Any suggestions on what could be causing this?
I am running a RAMPS 1.4, NEMA 17 68 oz.in stepper, Pololu A49888 driver, Sprinter and Pronterface. I tried to see if it would work if executed through g-code generated from Slic3r but same issue. I have also swapped the driver with the y-axis and the problem still persists on the x-axis.
SOLVED: I reduced the homing speed by 1/3rd (from 1200 to 400) and it works fine.
