Describe your issue:

A few days ago, after a print finished, some filament got stuck in the nozzle after running out of filament (i forgot to setup the filament run-out detector), after getting it cleaned up I homed the printer and when it reached the Y-axis it kept moving in the direction (making quite an unpleasant sound). After 5 seconds it triggered and finished the home without further issue. After it finished I checked the origin of all axis and they were correct. This hasn’t happened before, and I don’t know how to fix it.

Help would be greatly appreciated.

Have you checked the switch and the cabling are in working conditions.

I followed those steps and tried triggering the endstops, but they remained in the ‘open’ state. I also have virtual endstops, so no cabling issues. Here is my printer.cfg if it helps: printer.cfg.txt (6.5 KB)

Maybe you have to recalibrate the sensorless homing parameters.

Yep, that fixed it. I incremented the driver_sgthrs value on the y axis and it eventually found a value that didn’t scrape the endstops.
