Green filament was on head 3

When the XL put that tool back on the holder, did I seem visibly mis-aligned?

When the error occurred the 3rd head was over the bed. When I moved the filament to 5, it seemed to put 3 back without misaligning it.

Hmm. Weird. You didn’t happen to take a picture of the error screen, did you? Or somehow capture the error number?

No, I forgot to. Will snap a pic next time if it comes up.

Thanks. We’ve seen tool changer problems before when trying to dock/undock, and it’s usually just a matter of recalibrating where the printer thinks each dock is. I haven’t seen a tool changer error in midflight. I wonder if the tool came loose in the moving part.

I ran a print this evening that had a lot of changes to/from tool 3, and didn’t see any problems. I’m going to call this “fixed”. Please open a new report if you see this problem again.
