Ultimaker 2 upgraded to plus - hard to load filament

Recommended Posts

Ever since upgrading the ultimaker 2 to to a 2+ I always have issues loading filament.

everything is going smoothly until the last section where filament goes into the extruder, it always seems to be misaligned and blocked.

back gear tries to push but it can't go anywhere because it is hitting the extruder in some way.

I have tried to push Bowden tube down further but it's not helping.

also with the firmware it seems like if I am unsuccessful and cancel then try to start again by retracting the printer never gets to 100% to start to retract, I have to power the machine off and then restart when it's cooled down.

any help would be appreciated.

the prints are amazing but loading filament has been a real drag with the 2+ extruder.

It's getting caught in the transition between the bowden tube and the TFM (the milky white piece in the middle of the head). Often you can get the filament to get past this area by grabbing the bowden tube at the head and wiggling it back and forth.

If that doesn't help you can try straightening the top of the filament and cut it at an angle to form a sharp point.

Also, if you need to move the filament quickly, just push the lever on the feeder upwards and pull/push the filament manually.

    • "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.
