XYZ and Z calibration keep failing. Y axis seems to move too far
I had a print fail 3 days ago and came home to a mess off noodling everywhere. I tried to start a new print but it kept failing at the 4th point. I tried to calibrate it several times and finally noticed that it was moving too far on the Y axis. It would home in the front left circle perfectly fine. And it would do the first 3 calibration points without any issue. But as soon as it went to the middle 3 it was going too far so it missed all 3. I moved the Y axis to home and made sure the display showed 0 and when i moved it forward until it hit the pulley it stopped at 195. Any more and it would just grind. I have posted 2 videos of the calibrations on youtube but im not sure i can share them on here. This is a Prusa i3 MK2S assembled in April. Its been working perfectly till 3 days ago. Any help would be greatly appreciated.
