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?

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

If your motor shafts have a flat, try to make sure one of the set screws is against it
It seems that might be the problem indeed
None of the 4 moters had the set screw against the flat, so I redid all of them. It really makes sense to do it like this of course, but since this isn't mentioned in the guide I figured all would be well (and it mostly was).
Thanks for the prompt response btw @TheTik
hope it helps! 🙂
No squeeky noises so far! 😃
@Cruz can you update the guide to mention to put one of the setscrews against the flat of the stepper?
Thanks for the feedback! will add it as soon as I can
