What is the reason why the laser cutting machine starts but does not cut?

Generally, there are the following points that will cause the laser cutting machine to start without cutting or moving:

1: Accidentally hit the emergency stop button

2: The driver is out of power or the input voltage is less than 22V

3: Check the limit switch when the two axes of the machine can only move in one direction

4: The control card has no control signal output

5: The coupling or gear is loose

6: The pulse does not match the take-off speed, and the sound of motor with stationary gear will be sent out
