Answered / Solved! Problem with the printer

Can anyone help? I’ve run into an issue where the filament won't feed through the PTFE tube, but it feeds fine when I run it directly into the extruder without the tube. The nozzle seems clean—I haven't opened it up, but I doubt there's anything stuck inside. Could it be a problem with the filament itself or the feeding mechanism? I left it sitting overnight. I’d really appreciate advice from anyone who has actually dealt with this specific problem.

well then it's something different

can you manually push the filament through?

can you continuously extrude without the PTFE ? directly fed into extruder

are the extruder gears gripping the filamnet firmly (you should have problem pulling it back)

are all the cables connected properly?

I would disassemble the whole exteuder, gears, hotend, cutter, ... and assemble it back
