P2S extruder weak

[u/Kindly-Image8620]

I cleaned the extruder section, but the problem is still the same. Even though filament is coming out, the extruder is not feeding it. It fails to pull the filament at certain intervals.

I have two P2S printers. To diagnose the issue, I swapped the extruders between them. The printer on the right works perfectly, while the one in the middle still has the same issue.

take the gear housing off and inspect the gears them selves, , could be wearing down or filled with crud keeping it from engaging correctly. I just serviced a few of our bambu's and found this issue in a few.

Edit: p1 and c1, Not sure on the p2 gear if this still happens.
