ER204 - Z axis stuck or limit switch broken

If you are encountering this error, then the Z limit switch was not activated, when the system was expecting that it should. This most likely occurred because:

  • Something was blocking the way between the printing platform and the end stop
  • The limit switch is faulty
  • The connections need to be checked

To troubleshoot this error, its best to look at all the components involved. Check for:

  • Debris lying around the limit switch
  • Check if the limit switch is in good working order. Ensure that the limit switch is pressed upon homing the printhead
  • Check if the cables are properly connected

If the error persists, get in touch by raising a support ticket above.
