MK3S Y-Axis Length Error, Overrunning  

MK3S Y-Axis Length Error, Overrunning

I had a short circuit on my Einsy and I replaced it. Since then, I have had an issue with the y-axis. When I manually move the bed (by hand) with the printer turned off, I am able to easily slide it from end to end. I was able to calibrate the X/Y/Z successfully, but I ended up needing to replace the nozzle, and since then, I have had issues with the Y. I was able to run the first layer calibration, but when I tried to print a Benchy, the layers were all over the place in terms of the Y (literally seemed to be random and off by easily 10cm). Now the z/y/z calibration is failing, as is the belt test in the Y. Usually, when I calibrate or home it, the Y runs to the hard stop, moves, runs back into the hard stop, then it's zeroed. NOW however, it seems like the motor is trying to run it past the end. The motor is clearly still running when it's reached the hard stop. It's not grinding or anything though. No idea what this means, but to me it implies that the expected Y axis length is longer than it should be. I redownloaded and flashed the firmware again to make sure I have it correct. It's the latest, prusa3d_fw_MK3S_MK3S+_3_10_1_4697.hex.
