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. https://www.youtube.com/watch?v=EwERQwShS5g
