The video above shows the following strange behaviour on Ultimaker 2:

 

  1. Flow starts regularly.
  2. After few seconds the feeder goes in iper rotation.
  3. At the same time, the nozzle speed becomes very slow.

 

The problem appeared two days ago (my Ultimaker is 4 months old).

The problem persists with different gcodes.

The problems disappears if I restart the Ultimaker.

The problem comes back after 2/3 prints after restart.

What is it?

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
