We are newbies and learning as we go. Last week, we finally got all the motors working (x,y,z and extruder). Then on Sunday, after troubleshooting some jitters in the z-axis movement (changing the max feed rate to 1 etc) ALL the motors stopped responding. It sounded like a software problem, so we reinstalled all the software and firmware. Still no instructions to the motors to move. In pronterface, when we tell the motors to move, the x,y &z stay at 0.
Any ideas?
Build is Prusa Mendel i2 with RAMPS1.4.
