From time to time a filament will keep spooling and loading, back and forth until you get a warning that the filament can’t load. To date my solution is to just keep hitting retry until it loads properly. Check the spool and make sure there are not knots etc.
It would be great in these case if i have the ability to release the filament from the AMS slot to either replace with a new spool or to fix the one i am using and reload. At the moment the only way to release the filament is to stop the print
