z tilt issue
So I think I almost have my printer fixed except 1 issue. Its kinda odd, but here is what is happening
Once I get bed leveled old fashioned way, and do probe_calibrate I kick off z tilt.
Comes to front left, fine
Moves to back all is fine
Then moves to the front right and does the initial probe...BUT and ONLY on this step when its lowering the bed to move over to the front left 2 of the 3 z motors stop, the front right seems to lower another 1/2 to 3/4 rotation.
The motor does NOT do that on any other steps.
I have not replaced or changed anything related to z motors outside of replacing the board and drivers.
If it would do it on every step I'd replace driver it just seems odd that it only does that at that specific time.
Thanks

Can you take a video of it happening? Also can you upload your printer.cfg and klipper log?

There is printer.cfg, I'll work on the video next

Ok, here is video.. right around 19 second mark is the first instance of it happening.
Where is the klipper log file? Have you verified you plugged in the Z motors into the correct spot using STEPPER_BUZZ?

Sorry about that here is the log file. I ran the stepper_buzz when I first built it but not since, ill run those again
I don't see anything in here about z-tilt. Is this log from right after trying to do a z-tilt?

no, let me re-do it and I'll upload a better one

ok, here is good log
the first time it adjusts the front right Z -2.076195, the second time it adjusts it -4.752595. So either your mechanical system is binding and causing issues, or you have incorrectly wired the motors and it is trying to adjust them wrong because it thinks it is adjusting one of the motors when really it is adjusting another
