Ultimaker 3: Filament not extruding?

Recommended Posts

Please give us more information, which print core, which filament, which settings. If you can upload the Cura project, it would also helpfully, because then we can see the object and all the settings you use.

 

And, was the printer working before or have you unboxed the printer and this is your first print?

So you have loaded PLA material in Print Core 1 and PVA in Print Core 2, right?

Your picture looks like you print the object with PVA and not PLA. Have you checked which extruder is selected in Cura for printing the object?

Just wanted to update and close the thread. One of our printers had to be unclogged, that was one thing. The other thing is that before we print anything (if we haven't just recently) we move the filament to make sure some of it comes out of the printer head first, then we print.

 

In addition, we disabled the "automatic levelling" feature to never. We will manually do it once or twice a week, this held us up all the time and really the items come out pretty well without this double checking feature.

      We're not only trying to always make Ultimaker Cura better with the usual new features and improvements we build, but we're also trying to make it more pleasant to operate. The interface was the focus for the upcoming release, from which we would already like to present you the first glance.

    • "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.
