X-Axis Belt Clicks when moving.


When my nozzle move along the X-Axis there is a clicking noise. Also I noticed that the belt rotation thing on the right is moving quite a bit. The belt looks like bacon as well, but I am not sure if it has always looked like that or if it is rust. I have a video the problems as well. Please help me out.

It looks like your X axis idler bearing has failed.  To check, loosen the belt and try turning the pulley by hand (fingertip) - is it smooth?

Also check the thin part of the X end idler; if the nylock was pulled in too tight it can cause extra wear and collapse the part.  You may need a torch and a dental mirror to be certain.  If uncertain print the replacement part *before* disassembly.

My X axis idler collapsed and I replaced it with a twin bearing idler roller. 

Never had a problem since fitting the replacement
