Ultimaker 2 Material Feeder is no more loading material

Recommended Posts


I tried to change my filament following manual instructions.

Now when I try to start a print filament is not loading to the nozzle.

When I look at the material feeder it seems that the little cogwheel run idles.

I think I have to open the machine but I'd like to be sure before :)

Thanks in advance.

Here are some photos:

On the second one you can see if I draw a little bit on the wheel it come.

You need to tighten that tiny screw on the part you pulled out.

You will probably have to remove the white metal stepper motor cover in the left rear so you can see the motor.

You have to remove those 4 screws that hold the filament cover but when you do the motor may fall.

You have to slide that part back on and tighten it very very tight. Tighter than you might think. Remove the blue filament before you slide it back in.

Then you have to get it all back together which may be difficult without removing the white metal motor cover.

I just plugged in my brand new Ultimaker 2. The material feeder was not pinching the PLA plastic - I know because I painted a dot on the PLA before the intake and the dot didn't move.

I solved this problem by pressing the metal rotating pincher into the back of the ultimaker 2 more. No tools, I just pushed it in a bit more.

I had reasoned that the metal only had the criss-cross pattern towards the tip, and the PLA plastic might have been further back than the criss cross pattern. So I pushed the metal winder in a bit (not very much force) and it grabbed. I hope it doesn't wiggle its way back out again. For now, this has solved the problem.

I would recommend tightening the set screw in the knurled feeder (spiky metal part) at the very least as previously recommended, I have been having the same issues with the knurled sleeve coming loose, filament grinding, and with the filament slipping behind the feeder knobs (up against the back panel of the machine). Other than that the printer has been exceptional! I am hoping to print out and install IRobert's improved feeder design this afternoon.

    • "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.
