error using ultimaker cura - "unable to slice"

Recommended Posts


I installed ultimaker cura to my computer and after i put an item into it and press "prepare" it doesn't work.

Instead, it writes a message on the screen "Unable to slice, unable to slice with the current material as it is incompatible with selected machine or configuration". (the print screen is attached)

I tried to change materials and reinstalling the software and still i cant figure whats the problem..

if anyone know what should i do to solve it i will be grateful!

Thank you,

I am having the same problem with my new Ultimaker 3 and Cura 3.6.  I'm using Ultimaker Silver PLA in extruder 1 and Natural PVA in extruder 2.  Cura recognizes the Ultimaker 3 and detects that it has Extruder 1 and Extruder 2. 


Both materials are selected correctly in the Cura sidebar but there is a warning saying to "Check Compatability".  These materials are valid in the chart on the Ultimaker website. 


I have a simple STL imported that is small and in the center of the build plate.   I am using "Recommended" as my Print Setup.

I've not been able to figure out what is wrong and need help.

    • "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.
