Under Extrusion from Cura Gcode???

Recommended Posts

Good Day...  I have an odd under extrusion issue that seems to be caused by Cura 3.1. I've printed the same model in Cura 15.04.3 and had success with the ~same settings. It under extrudes in the same spot every time with the start and stop points. The rest of the model prints great and is rigid. It seems to be caused by the starting radius of the three ribs.

Material: PLA... Settings below... Has anybody else experienced anything like this?

You triggered me to check if Cura 15 solved the same issue you are having: indeed it helps using Cura 15x to generate Gcode!

There is something different in the generated Gcode between Cura Old and new...

I'm in the luxury position to have several UM to my command (UMO+, UM@+ and UM3)

Haven't been using the UMO+ because of the irregular feeding issues.

Changed: Nozzle, Heatblock, Teflon isulator, Tube, Feedgrinder: nothing worked.

Now i'm printing the second part with Gcode Cura 15: and it works like a charm!!


UM  do something about it!!!

Cura 3.1 737-Knob-Type1.gcode

Cura 15 737-Knob-Type1.gcode

Thank you for looking into it, I thought it must be the Gcode. I installed 3.2 Beta and had the same under extrusion in that area. The only thing that gave me success in that area was to turn up the heat by 10° and over-extruded by 10%. The part turned out reasonably well that way. I love the features in 3.1 and 3.2 compared to 15, so I hope they can find a fix.

    • "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.
