Homing problem

mendelevium

i have managed to set the TMC2130 in a ramps 1.4 run printer.
my problem is that when the homing takes place, the printer would grind again at the stop and make an aweful noise.
stallguard seems to be set ok because if i place a spacer while homing (which would cause the homing to shift) and remove quickly, the printer would home but attempt to move about 30 mm furher towards the stop.
what is going on? Any leads?

Homing always goes 2 times towards home direction. Between it should make a back move to untrigger endstop signal. So make sure the back move is not set to 0. Sounds like that is your error.
