Also see the ReadMe for the OctoPrintPlugin here:



The Ultimaker 2(+) family uses a flavor of GCode named UltiGCode. Unfortunately printing using UltiGCode flavor does not work when printing over the USB connection. That is why using OctoPrint does not work with UltiGCode flavor.

For the Ultimaker 2/Ultimaker 2 Extended, you can use "Machine Settings" on the "Printers" pane of the preferences to change your GCode flavor to "RepRap (Marlin/Sprinter)".

The Ultimaker 2+/Ultimaker 2 Extended+ currently don't support "Machine Settings". You can use one of these alternative printer definitions instead:



Ultimaker2 Extended+


Copy these files into the resources/definitions folder of your Cura application. Restart Cura and add a new printer. You should see the option to add a Ultimaker 2+ (RepRap) and/or Ultimaker 2 Extended+ (RepRap) (depending on which file(s) you installed.


Cura 2.4 will have support for Machine Settings with the UM2+ so it is easier to set the gcode flavor.

Ultimaker printers have Marlin firmware which doesn't let the extruder move unless the nozzle is above a certain temperature (170C?). Make sure you are in reprap mode. I haven't tried cura 2.X with reprap mode so I'm not certain it works but I think it should. If not cura 15.X definitely works. You have to tell cura that it is *not* an UM2 but instead a generic reprap mode printer.

    • Ultimaker Cura | a new interface
      We're not only trying to always make Ultimaker Cura better with the usual new features and improvements we build, but we're also trying to make it more pleasant to operate. The interface was the focus for the upcoming release, from which we would already like to present you the first glance.

    • "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.
