Random retraction in print Ultimaker 2

Recommended Posts

Hi Ultimaker Forum.

I have recently bought an Ultimaker 2, but it has some retraction promblems.

At times that seems random to me, the extruder on the back of the machine retracts the filament, causing the print to get minor holes in it. If I would print a solid 4 by 4 cm cube it would usually happen about 3 to 6 time per layer!.

I have noticed that it usually happens with the white Ultimaker filament.

Do any of you know how to solve this??

Any answers will be greatly appreciated.

    • "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.
