MMU3 on MK4 Idler won't Home
I have a MK4 that I've upgraded from an MK3s+ and an MMU3 that I've upgraded from an MMU2S. After the MMU2S upgrade, I began the initialization process on the printer and it gets to the point of trying to home the idler, but fails with an Idler Won't Home error and the only option on the printer is "Retry". I've been in contact with tech support for weeks now, and at their direction have disassembled and reassembled the idler body at least twice to provide photos and videos. they seem to be totally stumped as to what's wrong.
FWIW, the idler and all the idler rollers move freely; the only resistance I feel in the idler is that of the motor. There are no defects I can find in the prints of the idler and idler body and all the parts appear to be assembled properly.
Has anyone on this forum experienced this problem? If so, what steps have you taken to solve it?
Thanks

RE: MMU3 on MK4 Idler won't Home
Just a thought. I had problems on the mmu2 with the idler being rotated(not end for end but around it's axis) too far and then it would catch and not allow to rotate properly to home. I don't remember having that when I upgraded it to the mmu3 but I paid real close attention to the picture as to which side should be up.

This issue doesn't seem to be like that. When it tries to home it rotates back and forth a couple of times, making some rather nasty noises and then reports the error. But it rotates freely from stop to stop by hand, that's the puzzling thing.
