My extruder off my modified Ender 3 v2 is knocking and I can't find the sours off the problem. I've allready change the PTFD tube and made sure that it has direct contact with the nozzle. I also changed the extruder gear to a brand new one.

I'm cofused and hope to fix it with your help. Please comment and give tips, instructions and tutorials.
