Hello,
I recently brought an UM 2 extended. When I select to home, it moves to the left limit switch, As soon as it striked the limit switch it stops moving for a 5 seconds and the screen displays "X or Y switch broken" .
I tried exchanging the X and Y switch, no change!
Removed and again tightened all the rollers and rod's!
Bending the limit switch!
Updating the firmware!
Please help me!!! I am a beginner.
