Since updating to 3.7.2 XY axes no longer functions
Since updating to the 3.7.2 firmware off of the 3.7.2 RC firmware, I am having issues with XY axes movements when in the top right quadrant of the print space. I was getting layer shifts and other anomalies in recent days that have not existed.
Here is a video of the XYZ failing and showing a self-test succeeding. It seems like the right rear calibration point is no longer being detected by the PINDA but the first two points are. This seems to be causing a skew and the printer to exceed the print boundaries for that segment of the bed until it errors

Note: at times I shift the paper to verify clearance that the z height isn't going under minimum tolerance.
Printer was originally a fully assembled Mk2S, to 2.5, to 2.5S.

I played around with it a bit more and did another calibration and leveling… its almost like the printer things the bed is larger then it actually is. Is there something that would cause the firmware to lose its sizing. Either something that could be causing it to miscount steps from the motor, lose the bed size, or amplify X and Y translations from the 0,0 reference so that the further it gets from that point the more error it gets. Would also explain why there is a layer shift I noticed in the days before I sent my report in to prusa support. each time it does a new z-height layer it was a little more off since it couldn't re-home against the probe point used by auto home (since it was mid print).

Does anyone know the gcode to modify the multiplier used by the firmware to for Y axis translations. I want to try and decrease the y-axis moves by .5% or 1% to see if that resolves this issue. I have been talking to support and they stopped responding to me after a month of trying to troubleshoot this issue and am getting desperate to get working again. I am 99% sure now the issue was created by running a gcode provided that increased the Y-axis multiplier from the default and that is why everything overshoots on that axis past the printable area.

do a factory reset with data clear and then rerun the calibration wizard
RE: Since updating to 3.7.2 XY axes no longer functions
Thanks for the idea. I tried that again and it didn't resolve the issue. I just cant figure this out and I am afraid I may have to send it back to Prusa to figure this out. The pinda seems to work but it keeps exaggerating Y axis moves so things cant find the calibration marks. The Y axis is originally assembled in the factory, so I don't think it is an assembly issue and the belts are all fine. It just keeps overshooting.
