Printer goes past endstops
-
My printer skipped steps and crashed into the endstop but didn't stop. The endstops are used for homing and work fine but don't stop the printer while its printing. I also verified that they trigger properly with M119. How do I set the behavior if an endstop is triggered?

Endstops only stop movement during a homing move.
If you want them to act as a stop during normal opperation you can reconfigure them after homing to act as a trigger that can do an estop, (or whatever actions you want).

In your homing files at the start you'd want to have the normal endstop configuration so that they work during homing. Then at the end, reconfigure them as a trigger. Or enable the trigger only during a print by putting it in your start gcode after homing is finished.

@Phaedrux Thanks. I thought the endstops became estops automatically.

@Phaedrux I added M581 but it just always triggers as soon as the print starts. I tried S0 and S1. The head is far from either endstop when the print starts so I know its not touching the switch.
M581 T1 X Y S1 R1 ; set endstops as estop and pause on trigger while printing
