trouble with material flow?

Recommended Posts

hi,

I have some trouble with my ultimaker 2.

when i set the bottom layer to 0.1mm i get gaps in what should be solid.

see image attached.

when i set it to 0,3mm it works fine.

bottom speed is 15mm/s so not vast.

material is PLA

Any ideas?

looks like material flow is not enough or is there a known issue with cura v15.02.1 ?

When you print 0.1 if your first layer is 0.1 you need to do a very very fine calibration. At 0.3 the first layer has more room for error. Try using a bigger firstlayer or adjusting the thumb screws equally so the bed is closer to the nozzle.

    • "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.
