My first annoyance is it stopped. With the AMS and it set to refill if another spool of like material is loaded, stopping is a failure to me. Most other manufacturers seem to crimp over or kink a dog leg in instead of tape, so when it gets to the end it pulls the entire amount in. Then the runout sensor can detect the filament being out, swap to the next roll and continue the print without issue.
Now this part may have been my fault on the best way to handle this, but to resolve I then cut the filament off, it immediately fed up Into the tube and past the drive motor and stalled. It wouldn't let me switch to the other spool with the same material as it detected a fault vs running out, so I ended up just stopping the print as it was close enough. I couldn't unload the nozzle as it wasn't engaged with the drive, so I ended up moving another spool into that position and force feeding that initial tail thru the nozzle to get it out. It it wouldn't have had the taped tail, it would've finished the roll and moved right to the next one seamlessly.
