No warm up phase


I am brand new to octoprint so I might have missed something in the set up phase, but my problem is when I choose to print from the web interface, the printer immediately starts to run the lines like it is printing. It does not try to warm up, the bed does not raise and it just starts to go layer by layer.

Octopi Version is the latest release. 3d Printer is Ultilmaker 2+. No 3rd party plugins have been installed.


I think I would look at the GCODE which the slicer generated. You might share the first 50 lines of that with us here.


Make sure to not generate "UltiGCODE" flavor with your slicer - that's incompatible with any host and only works when printing from the Ultimaker's SD card.

I've tried to work with someone from Ultimaker in the past to get this somehow solved in OctoPrint but they basically said to not bother because that flavor was a mistake in their eyes. So.. yeah. Use "RepRap" flavor.


Here are some of the lines of code. I can see at the top it did generate the 'UltiGcode'. How do I change the flavor exported from Cura?

Cura -> Settings -> Printers... -> click yours -> Machine Settings -> G-code flavor


Note that there’s an OctoPrint Connection plugin in the Toolbox in Cura that will let you print directly to OctoPrint from inside Cura, and it will also set the gcode flavor for you.


that fixed the issue. Its all running properly now.
