Hmmm, huge burnt up glob of filament that was stuck to the nozzle, came off, cooled and then caused a layer shift?
Just a guess from what I can see.
Just playing a guessing game here...
The nozzle was probably already loose, for starters. It may have been possible for the nozzle to catch on the print with a blob that was forming from the loose nozzle.
Once the nozzle was stuck to the print, it got ripped off the bed and the movement of the gantry likely caused the print to spin. If a "leg" kept getting caught on something during travel, that would make sense.
After a few dozen moves, presto! Nozzle is unscrewed and is now one with the print.
Unless something in the hotend was actually broken to cause this, it's a perfect example of why nozzles should be tightened at a higher than normal temperature. Loose nozzle == bad time.
mostly out of the box one of these https://kingroon.com/products/official-kingroon-kp5l-3d-printer
I could be remembering wrong but kingroon are mostly groove mount v6? It's even more puzzling. Are the threads ripped off on the nozzle or block or did it unscrew itself?
I didn't check but the threads on the hotend are in good shape. It must have unscrewed itself. I think I can barely see some threads in the picture.
I had just put it on hot earlier that day. I must not have tightened it fully I don't have any other explanation.
Ah OK, the thread on the nozzle just looked too short and a bit like it was broken at an angle.
