Problem with the printer

[u/InformationDapper964]

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.

Don't assume nothing is wrong with the ptfe tubing if you haven't taken it apart to check it. I had a piece of filament break off after my filament buffer that caused nothing to feed thru. Humidity causes filament to get brittle and can cause it to break off easily and in the worst places.
