I’m printing with filled (wood, metal) filament, and the nozzle keeps clogging, what do I do?

Your nozzle may have too small of an orifice size for a filled filament to be extruded correctly. If you are using a 0.4mm nozzle, then switch to a 0.6 or 0.8. This will help eliminate the chance of the fibers/material specks in the filament from getting all jammed together in the tip of the nozzle.
