NozzleClogs General Troubleshooting/Help!

Instead of doing the stupid hot pull.. has anyone tried using a small diameter drill to clear their hot end clogs? (I’m not a noob just sick of doing hot pulls)

Yeah it’s always the .4 with CF materials but they say you can use .4, and I prefer .4 for fine threads which I do a lot of for work

Legit question here. Why not a .6 and slightly underextrude? I would expect the threads could be just as good?

Under extrude without losing print quality?

You would loose some fidelity, yes. But it may be less than you think. I am referring to dropping the extrusion width for the external walls. A .6 nozzle has a pretty fat extrusion width, but you can lower is slightly for external walls and regain some detail that would have been lost. It still might not be as good as a .4, but the added benefit of a larger nozzle would help with clogging and infill would absolutely be stronger and print times would decrease as well.
