New X Y motors stall problems
-
Hi , i changed my X Y motors to E3D with 0.9degree and now my homing absolutly not working . its crash and crashing than stop with error Homing Failed .

You're using sensorless homing and just changed the motors, so you will need to retune the stall detection parameters.

@phaedrux
and how i tune it i changed :

You need to read that link carefully. Have you calculated what your M915 H value should be? You've doubled the number of steps per mm.

@phaedrux how i calculate it ? m915 H
Im added H400 to M915 changed S to 0 and now its homing X and Y fine . -
@savethepetko from the page @Phaedrux linked:
If it's working reliably for you, then all good, but might still be worth going through that guide properly as stall detection can change a bit as the motors heat up.
