[FR] different driver current for sensorless_homing #15686

Closed danym21 closed 4 years ago

danym21 commented 5 years ago

Description

I use TMC5160 stepper drivers, since I use 0.9deg/step instead 1.8deg/step motors stallguard is not triggered correctly with the the current that I use for printing.

as example for printing I use a current from 1100 mA and "STALL_SENSITIVITY 2" the machine is crashing, when I use "STALL_SENSITIVITY 1" Stallguard is trigger often in the middle of the way to the edge. When I use a current from 462 for homing with "STALL_SENSITIVITY 2" all is working fine but on printing it is losing steps.

when this is useful for all, then I will share my code changes that I testing at the moment. I add additional settings in the configuration_adv.h and changed the G28 source code. at the moment it is working fine for me.
