Ultimaker 2 Grinding Filament. How can I fix this?

Recommended Posts

My Ultimaker 2 has been working find and I'm currently trying to print something in a new colour. I used filament I bought from faberdashery.com and I'm not changing to the Ultimaker brand filament which comes on a spool.

I just changed the filament and as the machine started to print, nothing was being extruded. I then went back through the steps again to make sure that the filament was being extruded which it was. Still no luck with the print. I tired one last time and as the Ultimaker feeder reversed to remove the filament nothing was being pulled through. I managed to get the filament out and noticed that it had been ground down. I tried to re insert the filament and the feeder is now grinding filament and won't pull the material through.

Has anyone had this issue or does anyone know what could be causing it? Any help would be great.

Thank you.

When you insert the material does it actual come out? (During the change material procedure?)

If not it might be stuck at the entrance of the teflon coupler.

I usually cut the filament in a pointy shape to make it enter easily in the teflon.

If it's grinding it means that something is blocking somewhere

This is just the start of your learning curve (I am guessing you a recently starting with UM2 from your number of posts) you knowledge will grow,

A couple of things you may want to read up on are "atomic" clean (of the print head) and look at improved fialment feeders that you can print

welcome to the forum and good luck
