Loose belt

I noticed jumping of the laser head. I looked in and the left belt is loose and sagging. I have read other listings of this problem but never the resolution… any help??

Did you miss this post about tightening the belt? I think it would apply here.


Well thank you. No loosening required for that fix. the pulley was sliding free… set to proper tension and tightened it. Thanks.


I am so sorry to see you are having trouble with your belt. It looks like all this needed was to secure that pulley. Thanks @marmak3261 for the quick help with this one!
