My MK2s has developed a strange problem where the x axis will bind up whilst printing. This causes it to layer shift. THe strange thing is I can move the x axis manually. It doesn't bind up and feels smooth. But half way into a print, I heard the x axis makes a scrapping sound thats distintive to it struggling to move.
THe bearings are still the original bearings but have had very little use. Maybe 30 hours of printing if that.
I have already taken the x axis apart and cleaned it with some bike cleaner( didn't have enough alchohol to form a bath. Before I cleaned it, it was't moving smoothly along the rails. Now it does move smoothly on the rails but did bind up mid-print.
I have checked the x axis belt, it doesn't seem to be too loose or tight. I tighten the the screws thats adjusts belt tension by hand so I doubt its too tight. It makes the distintive sound of a guitar string when you run your finger across the belt.
Am thoughly confused.
Could it be a bad bearing?
