Does anyone believe that the belt featured in this video is too loose? The adjustments are as tight as possible so I believe it has stretched out. Ordered a new one but misumi didn’t have the 4mm wide version so I ordered the 6mm which looks like it should work
Edit: it seems like the video isn’t working so I have uploaded it to YouTube
It’s likely the belt didn’t stretch, but something got bent. That motor holder doesn’t look like it’s incredibly rigid – belts don’t tend to stretch to that looseness.
