r/Ender3Pro

How tight should the extruder spring that clamps the filament be? I’ve had under extrusion problems on my last print and I tried checking if the plastic arm was cracked but it seems fine, also wondering if I should upgrade to the fully metal one and if it is worth it.

The last layers of the print were fine because I was manually helping the filament push into the hot end from the other side of the Bowden tube. Also could it be the friction from the filament spool grinding on the spool holder?

I print pla at 220°C and I have that inconsistent extrusion issue. I have no idea why... Can you help me know why ?

I'm using an ender 3 pro slightly modified, and running klipper.

I sliced it in orca slicer.
