Ultimaker 2+ with Octoprint

Recommended Posts



I'm trying to get Octoprint to work with my Ultimaker 2+, but to no success. I've finished the Octoprint setup, but nothing will print.


I'm using Cura for my slicing and RepRap Marlin. I've set up starting and ending G-code, which works well. However, I always get a warning message on the printer saying 'This file will override settings from the slicer'. My issue is that the printer's display is stuck at 'Printing from USB', so I can't do anything. I assume this warning is displayed because I'm not using UltiCode.


TL;DR: It will run my starting and ending G-code, but I can't get past a warning dialog to print the bread and butter.


I've scoured the forums, but couldn't find anything that worked. Any help would be much appreciated.

First of all: Welcome to the forum!


Well, you'll get the warning message on the printer if you start a non-UltiGCode file from the sdcard, that's normal. It should switch to the 'printing' screen as soon as you choose 'Continue'. You said the start script is processed, so i guess you get at least that far?


You'll get the 'Printing from USB' screen as soon as serial data is read from the USB connection. That's normal too, because everything is controlled from the print server (Octoprint) from now on.


Is it possible that you just have to wait until the printer is heated up to the target temperatures that you've set in the start script (hopefully...).

Which warning dialog (in Octoprint)? Can you elaborate this a bit more?

    • "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.
