Hallo everyone, I hope someone can help me with my stepper problems. My Ultimaker was running perfect for about 3-4 month. Now for two days my Z-Axis stepper is only moving the platform downwards. If I manually move the axis with my Ulticontroller, the platform lowers always (turn clockwise and counterclockwise). (the same result by PC-USB controlling) What I´ve done so far: - change stepper driver with another axis (same problem with the Z-Axis) - flashed Firmware many times - inverted the axis in the firmware - checked the endstops (the endstops are working correctly) - checked the cable connections Thanx for help Mighty
