@moth4017 Mine stall at first homing, X would stall, but if you get X to home successfully. Home all work every time, but if printer is power off overnight in the morning you have to go through that procedure again.

Try using M201.1 to reduce the acceleration during homing.

What did you end up changing to get it right?
-
@moth4017 i added the M201.1 x300 y300 just before the stall detection setup
-
@moth4017 I don’t know what’s going on with my setup because mine works for a few days and the have homing problems and then works again, I guess it’s have to deal with it the way it’s working.

@Karim post you config and homing files
