Machine homing step motor runs a little after

When I home my machine it hits the switch, stops for a brief moment and then will run for about a half a second grinding the motor. Is this normal.

Once it touches the homing switch it will back off i think like half a mm or a mm then slowly will go up and touch it and stop. Maybe you are hearing it ease up the second time.

Does the homing sequence for X&Y begin after Z or does the machine halt/throw an error?
(Check Easel Machine Inspector, CTRL+SHIFT+D for status alerts)

The slower your stepper “step” the coarser it will sound, so it can be normal.
If the machine finish homing and is carve-ready then its normal. If the machine throw an error during homing it is not normal.

When this happened to me the pulley was loose (I.e. check the grub screw on the pulley)
