Squeeky timing pulley
Hi, I've upgraded to IDEX and redone all the belts and re-tensioned everything. The timing pulley on the left X now makes a tiny squeeky noise for every full turn. I've narrowed it down to the set screws, if I untighten them, the squeeky sound is gone, so my only conclusion is that they somehow scrape over the motor shaft when moving... I've tried a lower belt tension but this doesn't seem to help a lot, only unscrewing the set screws.
So my question is actually: how important is it that these screws are set? I guess the pulley can now move a little with the belt, but is this a big issue? Lot's of belt wear or something?

Solution
those screws should be tight against the shaft and should absolutely not be sliding around
