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.

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.
