Ultimaker 2 under/not extruding suddenly

Posted · Ultimaker 2 under/not extruding suddenly

So I've run into a problem with extruding on my Ultimaker 2.

I've performed multiple atomic pulls, the last two of which came out clean, and leveled the bed again as well. Nothing seems to help and the filament just seems to come out verrrry slow or not at all.

I recorded a crappy video that hopefully shows what I'm experiencing if anyone in here might have some insight:

You might want to check the Teflon insulator look here for instructions

It also looks like the space between the Teflon insulator and the steel coupler is to big. It should be around 1mm. Maybe some PLA has entered between them causing a clog higher in the head?

Other things to check:

Filament diameter (must be 2.85mm (with tolerance) not over 3mm)

Rear fan (but it looks like it's working in the video)

Bowden tube friction (is it damaged?) is it well inserted in the Teflon?

Grinded filament, can add extra friction in the bowden

Aside from what Didier said which will explain why you are not getting a proper feed on your filament, I think your bed is too far away as well. Try loosening up the screws a little to get the bed a bit closer to the nozzle.

      Through this post I would like to further explain what we are doing, and what you could be doing. 
      Our efforts consist of 2 layers. First; connect medical institutions and hospitals to (local) 3D Printing hubs to help them print parts of which a 3D model already exists. And second, contribute to design the necessary part and then have it printed via a (local) 3D printing hub. Experts are available from within Ultimaker and from within our network of 3D printing experts.
