Hi everyone, I'm extremely new to this. Only had my printer a little over 10 days and i'm getting this exact same problem but my belts have not yet frayed. I noticed the problem after I heard a squealing noise coming from the general vacinity of my Y axis stepper motor I have tried repositioning all the pulleys and have levelled the bed several times since doing so. In addition to this I cannot get rid of the squealing noise and or the twisitng motion in the short belt on the Y axis motor. Do you think I need to replace the belt due to a permanent deformation? Any help or suggestions would be much appreciated. Many thanks, Adam.
