Colorfabb Glowfill grinding on UM2

Recommended Posts

Hi, folks!

After two weeks of trying to get a good result I decided to create this topic in the forum. The crux of the problem: due to the lower density of the filament when printing with retraction feedre start to grind filament, and because of this, the filament is absolutely not moving forward. Is there a solution for original feeder, or necessary to replace the modified one?

Hi Ivan, I found with WoodFill being a softer filament that the pressure on the feeder needed to be reduced to stop it squashing, also if you have a lot of retractions in the same small rear the feeder is constantly back and forward on the same small area of filament again squashing it down, if it gets too squashed then it will either not feed into the Bowden tube or may be just not feeding into the heated head in which case the feeder grinds down on the filament still in the feeder.

If you haven't already I would highly recomend printing Roberts feeder and fitting that, much easier to adjust tension etc, I have also fitted the mod to the bearing that aids the concave groove helping to prevent squashing

    • 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.
