Ultimaker 2+ - Printing from USB Cura - Print nozzle just moves in circles

[kcroeyer 0]

I am trying to "Print with USB" in Cura on my brand new 2+, and after i've prepared the model and started the print, the print head just endlessly moves in a circle and then a zig zag. The print bed doesn't lift up, and no filament is extruded. At first I assumed it was some kind of calibration because it seems to be running through a pattern, but I cancled it after it had done that for 5 minutes or so.

I've read online that printing from USB is not recommended, but this seems like a whole different issue. Can anyone direct me to an answer? Thanks.

Have you changed your GCode flavor from "Ultimaker 2" to "Marlin"? Otherwise USB printing won't work with the Ultimaker 2+.

No, I'll try that and post results, thanks! Is that common knowledge or written in a guide somewhere?

The Connect to OctoPrint dialog contains this message:

That didn't seem to work. I am ok with saving to sd, it just seems strange that cura and um2+ don't play nice over usb out of the box. I have a friend who prints a lot who just saves to sd, is the normal workflow to avoid usb?

Sorry about my previous message, I was thinking you were using OctoPrint (which also uses the USB port, and hence also needs the gcode flavor changed).
