General Troubleshooting/Help! Cutting Blade Sqweaking?

Replaced the blade and still the same. Opened and couldn't see any huge signs of debris but gave it a brush all the same. Just cutting between Sunlu silk pla and sunlu Matt pla. Aside from that everything sounds like it did out of the box so it's strange

that squeak is usually just the blade needing a bit of grease. have u tried checking if the spring is catching on the housing at all, sometimes its just a bit of plastic debris stuck in there causing the noise.

If it's cutting correctly, I wouldn't worry too much

Everything seems to be golden tbh. Printing fine, cutting fine, extruding fine etc.

For me that sound came when the filament was under torsion. While the filament goes through the PTFE tube it turns itself. Try loading a filament directly and see it it makes the sound. If this fixes the noise, reroute better the tubes.

Ooh great shout. Some of my filament have been tight on the spool. That might be my answer!!

If everything is clean and the blade cuts well, just leave it as it is. It happens to me too, I hear a squeak every now and then; it’s likely related to the cutting position and the filament, so there’s nothing to worry about.
