Z axis moving wrong direction

  • I'm running Matter Control 2.0. All of the sudden the z axis is moving in the wrong direction. When it's supposed to level and calibrate, all it does is move up. I have a Robo 3D R1 Plus printer. I've uninstalled and reinstalled the software and the issue still persists.

    It may be that your x-carriage has come up and is not pushing the limit switches. I think Z can only move up when the switches are triggered. There were a few different designs so it could be something else but it is almost definitely the hardware.

    If you don't see the problem there you can export the terminal log and post the bits where you are moving the axis. That way we can see if the z axis is being told to move down.
