Sensorless homing problems
-
Hi all ,
I have a core Xy printer and i meet a problem when i make my sensorless homing on X and Y , 50% of time the homing work fine but 50% other the printer make homing and remake it 50X, like if the printer read the homeX.g 50 time.
Did anyone have an information about it ?

Firmware version? Duet board?
Please share the results of sending M122 and M98 P"config.g" in the gcode console. Copy and paste the text into your post.
Have you gone through the tuning process?
