The new firmware has a bug in the new homing code. The head moves slightly forward and to the right. If the head was in position 0,0, this causes it to collide with the front of the machine. I think the head should go backwards and to the left (always feeling the endstop switches)

To avoid this behavior, change the parameters $130 (X Max Travel) to 730 and $131 (Y Max Travel) to 446

In fact, the best solution should be to return to the upper left corner (0, 440) instead of the lower left corner (0, 0) after the cutting task is completed, but it seems that everyone is used to returning to the lower left corner.
