Not extruding during print
Prusa Core 1 L
It extrudes filament just fine when loading filament.
However, when it starts to print, nothing comes out.
And there is what sounds like a metallic rattling sound from the extruder when it retracts the filament.
New nozzle, Prusament PLA
RE: Not extruding during print
Probably a nozzle clog. Which nozzle are you using?

Brand new .4 HF nozzle

RE: Not extruding during print
It could be heat creep. PLA can get soft, then is gets squished by the extruder gear into an oval shape and then it no longer fits in the nozzle heatbreak tube. Check the position of idler tension screws on the idle latch: https://help.prusa3d.com/article/idler-screw-tension_177367
Have you had any successful prints yet?
RE:
printing well for months.
I've swapped out the nozzle and the filament.
Prints have been a mixture of PLA and PETG.

Run the fan tests and perhaps remove the heatsink fan and use some canned air to blow out any debris. I this point I would (if it were me) disassemble the Nextruder and look for debris or broken parts, strip the grease from the planetary gears and relube. If not comfortable with that then contact support over chat. They can walk you through dianosing the issue.
RE: Not extruding during print
Swapped out the HF nozzle for regular brass. Attempting again.
RE: Not extruding during print
The regular brass nozzle seems to be working just fine.
RE: Not extruding during print
This is the reason I don't use HF nozzles anymore. They are too easy to clog and are not worth the speed benefit.
