First load of ultimaker 2 is grinding fillament

Recommended Posts

I just got a ultimaker 2 and it came with a Olsson block.

The first thing I did was install the Olsson block, which went well. Then I followed the startup sequence on the screen, leveling the build plate. When it came time to load the fillament i fed it in back, then pressed next and it advanced near the end and slowed. It then slowly advanced until it stopped and started grinding instead of extruding.

Anyone know whats going on? I took the nozzle off and it's apparently the plastic never made it to the nozzle itself. so it must be getting stuck some where near the end of the clear tube.

You need to sharpen the filament like a pencil. It can sometimes get caught on an edge going into the nozzle if it has a flat end. Maybe caught on the PTFE coupler or something.

Also make sure the bowden tube is going all the way into the PTFE Coupler and everything is seated nicely. ( Olsson Block isn't on a weird angle or anything)

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
