I'm getting severe underextrusion issues to the point where I throw a G1 E100 F100 at my Ender 3 and it only feeds ~40mm at 200C. If I watch it I can see some "slips" of the feed gear where it tries to force more and can't. Have tried cold pulls, fresh capricorn tubing, swapped nozzle, and put provided needle into nozzle with no-go. Got a couple clean prints and now nothing good. Any suggestions?
