Cura won't connect to my Ultimaker

Recommended Posts

I just installed Cura on my PC. I had been using RepG with my Ultimaker for about a year with no problems. I decided to upgrade to Cura and upgrade to Marlin.

When I run the activation wizard, it can't connect to my Ultimaker. The software runs fine, and lets me set up a model to print, but it can't connect. I've attached an image that has some of my basic driver/pc info.

Please let me know if you need more information to help diagnose my problem.

Thank You,

Dan

Maybe something else is still "connected" to the serial port, the port needs to be free for Cura to connect. And serial ports in Windows can get into a "limbo" state, where windows thinks an application still is connected to it.

Try:

-Disconnecting the USB cable

-Restarting your computer

-Start Cura

-Connect the USB cable

-Try upgrading the firmware.

If that fails, could you try pressing the "print" button, that should show a new screen which fails to connect, but it will show a "error log", this error log might help in diagnosing the problem.

Sorry for the delayed response, I've been under the weather lately. Unfortunately I'm still having trouble connecting to the printer. Below is the error log from a failed print attempt:

Hi,

i am as new as they come to the Ultimaker. I just assambled one and tried to get it working.

Now I am stuck with a simple connection problem and can't find a way to fix it.

I run cura on Ubuntu 12.04 LTS

it starts normally and I run the first run wizard. When I try to update the marlin firmware I hear a sound like one of the motors turning(i don't see any movement) and then the process times out.

If i skip the process and get to the checkup I get a connection error with the following error log:

Changing monitoring state from 'Offline' to 'Detecting serial port'

Serial port list: ['/dev/ttyACM0']

Connecting to: /dev/ttyACM0

Error while connecting to /dev/ttyACM0: 'Timeout'

Failed to open serial port (AUTO)

Changing monitoring state from 'Detecting serial port' to 'Error: Failed to autodetect...'

I allready set the access rights but still get no connection?

What else could i try?

Thanks in advance,

Taires

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
