Cura shuts down when connecting to ultimaker

Posted · Cura shuts down when connecting to ultimaker

Hi everybody,

I encountered a very strange error.

The story is the following: after having trouble with flow options on my ultimaker I wanted to reinstall the marlin firmware.

I got cura on my notebook(ubuntu 12.04) because the printer is normally controlled via ulticontroller and not directly connected to the pc i first worked with.

So i plugged the ultimaker in, fired up cura and tried to run the firstrun wizard.

I worked through the wizard and pressed "Upgrade to marlin firmware". At that point cura simply vanished, as if closed. Being curious i started cura via console and did exactly the same and exactly the same happened. All the console read was:

taires@taires-UL30A:~$ cura

python: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.

taires@taires-UL30A:~$

 

And I have no clue what this means.

 

Help would be appreciated,

Thanks

Taires

    Hey Taires,

    just a few flaires....

    Is the printer connected to a earthed wall mount?

    Is the computer connected to a earthed wallmount?

    Your notebook will probably not, so try to connect the USB cable before you start up the computer and never connect or reconnect the power cable from the Ultimaker while the powerswitch is on. Connect your notebook powersupply even when the battery is full. And put them in the same wallmount. It could be a EMC problem I encountered myself with the same outcome.

    Otherwise, try another laptop or even a desktop pc, but with the earthing connected either way.

    Good luck
