[solved] four z axis machine is consistently failing to home

Subj: Machine suddenly started moving first one Z axis during first homing move in reverse
At first I was to ask "what do I do".
But then I've tried a few more things and it's homing okay now.Given:
Voron 2.4, was tuned and working perfectly for a year.
Updated RRF 3.3 → 3.4.5.
Worked for a day, now it fails to home.
For some some mysterious reason it started moving one Z axis down when probing first point.
This is consistent behaviour, happens every single time except first pass.
Obviously, deviation is so high it can never home itself.Tried:
Reverting to 3.4.4, 3.3, didn't change a thing.
Making it go super slow, no difference.
Raising probe offset, no difference.
Adding S-1 to probe points, refuses to home.
Adding S4 to probe points, refuses to home.
What was I thinking.What worked:
Increased Z current, decreased Z acceleration, tightened sloppy belt.Morals of this story:
Software developers are smarter than they think.Video evidence:

Increased Z current
What was the z current?
-
@Phaedrux it was 300, I've set it to 500
