Describe your issue:Can someone check out my cfg and log file, Trying to set up sensorless homing and have searched the forums for the last 3 days.
sensorless homing on x and y . Pinda probe on z
x reports “Endstop x still triggered after retract”
issue G28 command for z and also get Endstop x still triggered after retract.
At first glance, your
driver_SGTHRS value is very high for your X axis (which is what I presume you are trying to home first). What values have you tried for it?
Could I suggest that you work through a binary search approach to finding the right value? Start with 120 and if the problem persists, go to half the value (60) and run it again. Depending on what happens, go half the distance (to 90 or 30) until you have something that’s reliable.
I have worked down from 250 down to 60 and the motor grinds when it bumps, all sensors report as open
What happens if you increase the
run_current? You have it set to 0.5 right now which seems a bit low. I’m also not sure about your use of 32 for microsteps.
Could you try again finding the right
driver_SGTHRS with the
run_current set to 0.7 or 0.8? As this is a CoreXY system, you need to change both the x and y
run_current values. You might also try it again with 16 for microsteps.
What is “sensorless.cfg”?
If you wish to use sensorless homing you need to disable the second homing attempt (
homing_retract_dist: 0) - be sure to follow the directions at TMC drivers - Klipper documentation
