MK3S Y axis calibration bumping / jumping issue
Hello I finished assembling the prusa MK3S but im having an issue with in the first part of the set up wizard after the fans, the XYZ calibration. Ive included a video (Skip too 0:19 for the problem)
Before this the X axis actually failed too, but i had to tighten the back plate of the extruder since it was bumping into the walls. its much tighter now but i feel like it is too tight, but it did solve the problem and the extruder travels smoothly
I have read online for solutions for the Y axis, I tightened the Belt which actually made it jump a little less but still happens, I've loosened the U bolts but it did nothing. The firmware is 3.7.1-2266 I've checked the orientation of the Y plate and its as discussed in the assembly book. Any help please
