Suddenly will say "Failed to Establish Connection with the Printer"

Recommended Posts

All of a sudden, my computer will just stop being able to connect to my printer. I get the "failed to establish connection with the printer" error.. However, when I plug in the ultimaker with my USB cable, I get the "ba-dum" sound from windows, and everything is plugged in (I can hear the fan running).

It's strange, this will actually happen while I'm testing it. For example, while I'm doing one of the alignment runs, the block temperature will start rising, and then all of a sudden just stop.

Error log:

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

Serial port list: []

Failed to open serial port (AUTO)

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

Well, much the same with me. I run a print, then if I want to run a second print, I get "Serial Timeout exception" and the machine cannot connect anymore. Unplugging the usb cable, turning off the printer, restarting CURA, nothing works except a total restart of the computer.

Pronterface works all the time though....any ideas?

    • 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.
