UM3E Feeder Problem

Recommended Posts

Hey folks! I realize this is something of a common problem, I'm hoping I've got a little twist on it. So sometime in the last couple weeks I noticed our printer (a UM3E) started randomly failing prints by stopping extruding. I looked at the filament and found a nice little divot ground into it from the drive gear. Instantly thought "oh, my feeder tension must be off," so I started playing with it, but never fixed the problem. So I started looking at other things: cleaned the hot end who knows how many times, switched out the bowden tubes, cleaned the feeder assembly, etc. Checked everything on the second extruder, which worked just fine. Finally noticed that there was a channel worn in the side of the outlet on the feeder housing:

And for comparison:

Don't know if this might be the problem. I'm thinking the filament is having a problem staying centered on the drive gear and it's catching on either the housing or the bowden tube, which gets it hung up long enough to chew the divot in the filament. Anyways, I'm at something of my wits' end trying to diagnose this, definitely spent the better part of a week trying different things. Would love to hear if someone's had a similar problem, how they fixed it, or anything else I might try to solve the problem. Have people printed a new housing? Made modifications to the UM3 feeder? Thanks!

      The goal of this contest is to design a set of people figurines that could be used in such a project to make an area, office or mall seem populated. 
      Think of different types of people in different environments, like walking people, people standing still, working people, and both men and women.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
