nozzle doesn't appear to have round cross section error
I recently upgraded the firmware on my 5 tool XL to 6.2.5. I ran a few prints using just one tool because they were simple and small. Tonight I wanted to run a bigger print using spool join so I thought it would be best to run the tool offset calibration. When running the calibration, after the 5th tool completed, I got an error that "Nozzle doesn't appear to have a round cross section. Make sure it is clean and perpendicular to the bed." With a QR code that takes me to the sales page for the XL.
I verified the nozzle is clean and the extruder sits in the tool changer correctly. Any thoughts?

RE: nozzle doesn't appear to have round cross section error
I know you said they were clean, but maybe give them a good scrub. I've found that if you print things like PCCF they don't come off the nozzle by a brass brush. I've found that you have to literally scrape any buildup off.
Then try again. I have had the nozzle offset calibration fail, not with that same error, but just running it again it completed.
It's super important that the nozzles are pristine clean, because any small debris or plastic on them will cause the offset to be wrong, even if the calibration completes.
RE: nozzle doesn't appear to have round cross section error
I understand the importance of the nozzles being clean and I heated then up and cleaned then again and tried the calibration again with the same error before posting this thread.
It's interesting that I did run the print anyway with spool join and the cut over is barely noticable, so it's very close to being spot on even with the error.
There was a green check mark on the offset calibration indicating it was successful, yet I got the error. Not sure if there is a real problem or not...
Can't find anything on the site about that error.

Did you ever figure out what the problem was. I'm having the same exact issue as yours. I tried everything and I'm stuck. Any help is greatly appreciated
RE:
I'm wondering if it is a firmware bug. I didn't get this error until after I upgraded the firmware. I've recalibrated the offset a few times in the past because I would switch nozzle sizes without error.
As I mentioned above, I got a green checkmark indicating the calibration was successful, so it may be 'informational' rather than a true failure? Not sure. When I get time I might roll back the firmware and see if the error goes away.
I didn't do a support chat yet either, I'll try that later as well.
