Did you test with a precompiled firmware?
Yes, and the problem still exists.
Bug Description
At random points during the mesh levelling procedure, my CR touch probe will stow, but the Z-axis still goes down, causing the nozzle to crash into the bed and a NaN point to appear in the mesh. Happens in both manual mesh levelling and AML process.
Bug Timeline
At update to 20240125
Expected behavior
I expected the probe not to stow and properly probe the bed.
Actual behavior
The probe stowed at random time and the nozzle crashed into the bed.
