I tried connecting the motor using Dupont cable which I had and the motor vibrates but the shaft does not turn (the other Z-axis motor responds normally). It seems that the motor may be dead as well.

I tried the tests you suggested. When the motor is plugged into the X-axis cable it seems to perform correctly, but when the cable is plugged into the X-axis motor, the X-carriage does not move. This suggests that it is the cable. I removed the cable to check for continuity; the red, green, and blac...

I recently finished building a Prusa I3 Pro B (acrylic) and had everything working properly. Now one of the motors on the Z-axis is not turning in the correct direction. The other motor responds correctly to up and down commands from Repetier Host. However the second motor sometimes turns clockwise,...

Thanks. I discovered that after posting my question. X home still positions the extruder tip about 20 mm off the bed. This doesn't seem to make any difference when starting a print. Should I be using some sort of offset?

I just completed building the Pro B Prusa I3. The X-axis was moving in the wrong direction, so I changed that in the firmware (#define INVERT_X_DIR true). Now the extruder carriage moves left to the X-axis end stop when the Home command is given (using Repetier Host). However, once the X-axis is hom...
