Alright removed and checked alignment. I also went ahead and Fixed my settings. I slowed down my printing and took the layer height down a bit to make sure I was not forcing too much filament through at once. Going to run it again.
Yeah still the same thing. I am wondering if I should contact support directly. Anybody else having this issue?
Alright after working on this all day I figured out that when I installed the feeder I pushed the little plastic gear on the feeder motor back. I did not even realize that it would move. So the loud popping noise was the small gear slipping off of the big one because it was not touching it all the way. Hopefully this can help someone else. Maybe I was the only dumb one haha.

That can do it, let me know how you get on with your printing, I'm having issues with mine and its under extruding after 9 hours of installation.....(not high jacking your forum). have a look at my problem and let me know what yours does.
I'll have to check it out. I'm having similar problem - posted here. Check the end for video - though the video only shows the slightest bit. I have the printer upstairs, but could hear it knocking every once in a while from downstairs.

Maybe I messed up the gears on the install.
Edited by GuestAGH! So that is the problem - Not sure how to fix it because neither gear on my ultimaker seems to be able to move in or out, but if I turn the little slotted silver head on the back of the feeder it's causing the same issue - but skipping every 1/4 turn or so. Maddening because everything appears to be snug. I'm going to pull the feeder off again to see if I can get them closer - but I don't see how I can.
Edited by GuestOkay - I took off the feeder and did some measurements.
if my feeder is flat/flush against the metal plate on the back
As it turns out - overlap between the two gears is barely 1/32" (around .8mm) - so any shimmy at all and the thing skips.
So Ultimaker crew - we need a new gear, or some alternative solution. I'd print one to go over the old one - but at the moment I can't print.
Edited by GuestI just fixed my under extrusion problem......after getting a replacement feeder from UM and not fixing it. I swapped back to the old system and strangely fixed it! so my printer is working after 3 weeks of being broken! so I think the feeder system needs fine tuning....... back to the drawing board UM.

Hey - I pulled the gear off and put a washer behind it and now my UM2+ is printing beautifully. No popping, grinding or under extrusion. The washer pushes the large gear so it's almost against the metal plate on the back of the UM body, so I put a little grease on it as a precaution.

Yeah I used the grease. I may remove the feeder and reattach it just to make sure its aligned properly.
