I removed my external pla basic filament and disconnected the AMS however the software says it is still installed. It also shows an error stating that filament may be stuck. I checked all tubing and did not find any broken filament. I am using ver 1.7. Any help would be greatly appreciated. I just did a total factory reset with NO External Filament and NO AMS it still says there is a Green Spool of PLA on the External spool. Also tried to revert firmware back but it does not give me the option. btw forgot to say that the printer arrived 2 days ago and initially i was able to print a benchy but nothing since.
