I’m trying to use up 4 reels of PLA-CF I ordered by mistake, the A1 printer is 2 weeks old and has been working great using PLA Basic and other equivalent Sunlu High Speed PLA and Overture PLA. All of a sudden the hotend is clicking and is unable to drive the filament using the External Spool, I changed out the nozzle back to the stainless unit and tried printing something else using the AMS and it worked fine. So I reloaded the Hardened Steel nozzle, put the reel on the AMS, heated up the nozzle and cleaned the nozzle with the Bambu pin. Still no go the hot end just clicks away without feeding the filament.
Is there some adjustment we can do or am I missing something else.
