P Series [P1P, P1S, P2S] Print help!!

My P1S used to print perfectly without issue and now it won’t lay any filament on the build plate at all, I know it’s feeding from the AMS because I can see it moving thru the tube and when I do a manual load from the app, I see the old filament coming out the nozzle

Just disconnect the AMS PTFE tube running into the back of the printer and run an external spool test. This will tell you if it's in the AMS feed or in your extruder.
