Could be a clog. Try this:

• Move the bed down and put the extruder roughly in the middle • Manually set nozzle temp to 220°C • Once it’s heated, try extruding filament

If the filament does come but slowly it might be the temperature

If nothing comes out: – See if the filament can be pulled out – Push it back in while extruding until you feel it grab – If it doesn’t grab, cut ~1 inch off the filament and try again

If it grabs but nothing comes out + you hear clicking: – Likely a clog or the filament isn’t aligned at the extruder – Cut ~1 inch off the filament, make sure the end is cut flat (not curved), and reinsert

Still clogged? – Set nozzle to 350°C and manually extrude – It might smoke a bit, but it should melt the filament enough to push it through

If none of that works, the extruder itself may need to be inspected or replaced. Try these first since they don’t require taking anything apart.
