Under extrusion with Cura 3.1

  • I upgraded from Cura 2.7 to 3.1.0 and I'm getting horrible under extrusion, I'm sure this is the software because I rolled back to 2.7 and everything is working fine again.

    My printing is a Robo3D R1+ using the "custom FDM printer" profile.

    Is there any new setting or a setting that isn't migrated properly that causes this?

    Maybe give your custom profile parameter so we can have a guess at what could be wrong ? I don't think someone here has enough divination skills to guess the parameters on your software.

    This may be a bug, because my *new* install of latest Cura is creating the same problem AND I saw 2.85 one of the settings, so I changed it to 1.75 and it continued to under extrude severely. All was well with a Repetier print. Now reading above I need to also check both the machine settings and material section of the print settings.

    This is not a bug, Ultimaker default filament diameter is 2.85 mm, so that is what they default to.

    Some users have reported upgrades to Cura changing the filament size to the default 2.85 mm. If you are using 1.75 mm filament (which most printers do), you will get extreme under-extrusion.

    Thanks, that was it, the filament diameter was correct in the machine settings (that I checked) but not in the material section of the print settings

    Similar issue here but both settings were 1.75. I re-saved printer and material preferences and modified my custom settings and saved them. Now it works!
