My Ultimaker2 , Ultimaker2 ext, doesn't works well at low quality.

Recommended Posts

Hi friends,

My question is is why my Ulitimaker2 and Ultimaker2 ext is not printing well at layer height 0.15mm and 0.2mm ? at this low quality i get a very bad printing i never get it before like this king of printing quality from my Ultimaker.

while i am using latest version of cura 2.3.1 and also i updated my printers with latest firmware.

my printers working very well only at normal qality 0.1mm layer height.

please let me know how can i fix this issue?

I have also started having problems with printing at 0.2 layer height.

I used to be able to switch between 0.1 and 0.2 without problems or having to change settings but now 0.2 has become unusable.


I have tried different materials from different manufacturers and cleaning the nozzle in case this was causing the under extrusion but it has not solved the problem.

I have also started having problems with pillowing at 0.1 on models that printed OK previously.


In view of the fact I have had other problems with Cura 2.3.1 I have reverted to using 15.04.3 however this has not helped either, which leads me to think that something that has been changed in the firmware (which I have not put back - I don't know if that is possible) is causing the problem.

    • "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.
