I had been printing fantastic prints on my printer, and then I started to notice it was getting louder while printing. And then I started getting random print shifting. I noticed that the X axis would stutter and get stuck and the bed would have similar issues. It looks like the Y belt has some wear on the side making me thinking it's rubbing. I've found the x axis issue is intermittent and I can't complete a long print without it shifting. Amy suggestions how to fix? Are the belts too tight? Alignment of belts off?
It is recommended to adjust the belt to a proper tightness and check whether the belt is installed incorrectly.
