Hello to all builders! I am building cartesian printer 400x400x400 with replicape and manga.
Steppers for X and Y going now only in one direction. For reverse direction i hear only noise (that current goes in stepper). Few days ago it was working. When i switch the connector and connect Y stepper to Z driver or X stepper to Z driver, steppers are turning both directions. So i think problem should be on replicape or redeem. Any idea where can be problem?
Sounds like you may have shorted out a stepper motor, and possibly damaged the stepper motor driver. If you tell the motors to spin at a slow speed either direction, and then force the axis to move manually, does it move in a jerky fasion?
Shorted out stepper motor by wrong wiring or how it could happen? i had 3 times made wiring, so maybe i made second time some mistake in wiring, but now it is conected corectly.
Force the axis manualy when is moving and have jerky move, do you mean like missing steps? Move axis with bigger force that motor do? Yes clockwise it does, when i tell it to go counterclockwise, it only hold position. Please tell me that i dont have to buy new replicape :-/
After another flashing kamikaze, stepper motors are working both sides. Still don’t know what was exactly wrong… Now i will keep in mind to do not change default.cfg 
It may have been the travel distance in the config… I had the same problem when I was first building my printer. If it “thought” that it didn’t have enough room to move a certain distance, it would just make a low noise until I M18’d…
