Loud popping from the feeder after Ultimaker 2+ upgrade

Recommended Posts

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.

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.

AGH! 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.

Okay - 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.

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.
