Trouble with Cura (What am I missing?)

Recommended Posts

Posted · Trouble with Cura (What am I missing?)

I have a brand new Ultimaker 2 Extended and the pre-loaded print jobs are coming out beautifully, but I can't print over USB from Cura. Every time I try to print an STL file, the machine starts going through the motions of the job, but without homing or bringing the extruder and bed up to temp, so it ends up just waving the nozzle around in the air and tearing up the filament.

I've tried looking at the help and searching for help but I can't find anything related to this. The STL files I've tried so far were created a few years ago in OpenSCAD. They look fine in the preview pane.

Hi @NonSequor,

That is true. We no longer support printing over USB because it is not as reliable as printing over SD card. The USB port is only for updating firmware.

If you want to start your own print, copy your gcode from Cura onto the SD card and fire up the print through the interface.

Did you select the Ultimaker 2 Extended in Cura or did you use another printer's profile?

It's possible to print through USB but unreliable - I don't recommend it for more than a 20 minute print. But you have to choose "ulti gcode mode" in cura.

Uhm... isn't it rather "Reprap gcode mode"?

Oops - yes I got it backwards. You need reprap mode.

I would like the feature to command the printer thru USB. So that you still load the g-code via SD card, but you can remote-control it, order print to start, stop or pause, control lights, ETC... that should be fairly safe for usb connection, right?
