Should I be worried (UM2 rod sticking out - solved)

Recommended Posts

So far it doesn't appear to be an issue, but I have noticed that the bar, front left of the UM2 moves out while printing. It only sticks out about 1mm and is easy to push back which I do after the print is finished but wondered if I need to do anything more drastic to stop this. As yet it doesn't appear to move further each time so seems to reach a limit.

Yes, the only pulley that is necessarily loose is the one closest to where the rod sticks out. So push the rod all the way in, and then loosen that pulley more, and push it (and the spacer next to it) up against the bearing, and tighten it down hard.

Even screws that 'seem' to be tight in casual inspection can allow the pulley to gradually precess along the shaft. That can get to the point that the rod falls out of the bearing at the other end mid-print. Mine did. But once the pulley is repositioned, and tightened properly, it should work just fine.
