Cura 14.02 versus Cura 14.03

Recommended Posts

Hello all,

My last print with the new cura 14.03 gave bad results, here are 2 pictures of the same object printed with both cura 14.02 and 14.03.

With cura 14.03 every circle shape part are very bad.


The result was even worst than what you can see on the picture (actually I sanded the part a bit)

I used default settings on both print and same temperature same filament and same height (0.2)

Do you experienced something similar ? Do you know what is causing this bad result ?

Thanks in advance!

Which RC did you use? There were several RC which were labelled with 14.02. Or do you mean the last official version before 14.03? This would be 14.01.

Did you check the gcode? Is it different for the two versions? Some people like Repetier-Host for such comparisons, I prefer the gcode viewer at http://gcode.ws.

When printing the same object from older cura consider doing:

file "load profile from gcode..." and then choose the older object you had sliced. This will load the newer cura with the older settings.

Can you post a link to the STL file that you are slicing please?

Yeah, getting the exact same results here, 14.03 is unusable. Posted about it in another thread already, but will actually take a photo of a comparison I did the other day. 14.03, whether USB or via Ulticontroller, slows down drastically during curved sections and causes massive overextrusion there. The same files print fine using 14.01, USB or Ulti.

@Daid, Does that problem will be taken into account as a Cura "bug" ?


I think it's the same problem as reported as the speed issue. Where 14.03 is generating too many small segments for high detailed prints, causing the printer to slow down (with all quality problems as result)

    • "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.
