Did you test with a precompiled firmware?

Yes, and the problem still exists.

I use that version, Ender3V2-422-BLTUBL-MPC-20240125 and don't have this problem.

mips42 commented 4 days ago

okay, Good. I guess. I do. I am now checking Z before every print because I never know when the setting is going to change. While this mitigates the problem, it foes not solve it.

mriscoc commented 3 days ago

Maybe the motor drivers of your printer don't support the increased speed and acceleration of the new firmware. In that case it is better to return to the stock firmware.

mips42 commented 3 days ago

I suppose its possible but I'm not sure why it would affect only the Z offset. I might switch back but Id miss the viewable mesh.

mriscoc commented 3 days ago

Each driver is independent, in the case of Z axis during the home and leveling operations the axis changes the direction several times.

Add-on: after a successful print yesterday, I went to exit back to the main screen and the control knob was non-responsive. After about 5 seconds of this, the system rebooted and the z-offset was reset to zero. I dont know if this helps or not.

mriscoc commented 1 day ago

the z-offset was reset to zero

Only the Z-offset was affected or all the settings returned to default?

mips42 commented 1 day ago

Not sure I understand. The Z offset is all that I am changing so, Yes?
