x axis occasionally binding up whilst printing
-
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?

Is the driver current set too low?

I have it set to 1 amp
Could it be to do with I broke the back plate that rides on the x axis? See the attached image for a better idea if what I broke.
It's currently zip tied in place. I gonna purchase some prusa orange PETG to print the replacement part.
What's the maximum current the driver can supply?
But I do have the other motors set to 800 mA and I don't have stalling issues. Even the z axis is set to 800.

Best to replace the part first and see how that goes. If the motor current is already set appropriately for the motor you shouldn't increase it. I mainly asked in case there were places in your macros that you dropped the current for some other reason and maybe it wasn't getting returned to it's normal value.
