a 3d printing business can be a pain in the butt.
so the weird thing is, humidity was at 12% which is actually fine for printing. but the nozzle was completely clogged and the CF filament had been eating itself all night. i run a small farm of these printers and 2 of them were fine, the rest were toast. same room, same conditions, same filament. no idea why.
so i pulled the whole nozzle apart, cleaned every piece, did a cold pull to drag the muck out, recalibrated the printer from scratch, ran a flow dynamic calibration, basically the full reset. still wasn’t enough. CF filament is way more abrasive and clogs way faster than normal stuff, so the nozzle just keeps gunking up mid print.
ended up finding some custom g-code on reddit that tells the printer to wipe the nozzle automatically every 10 or 15 layers. loaded it in, hit print, walked away.
came back to a clean print.
anyone else running CF filament with a similar issue? curious what your setup looks like.
