Cura not connecting to Ultimaker but Proterface will

Recommended Posts

Posted · Cura not connecting to Ultimaker but Proterface will

Hello,

I have been having a problem for the past few days with Cura not wanting to connect to my Ultimaker. I have looked on the net and have tried disabling the driver, uninstalling and reinstalling the driver, restarting my computer with the USB cable unplugged and still cant get it to work. The weird thing is that Pronterface will connect just fine and everything works. I know both Pronterface and Cura cant connect at the same time so I fully disconnect and close Pronterface before trying Cura.

Cura has been amazing since I got my printer and I dont understand what has changed. I have tried versions 13.11, 13.10, and 13.06.4.

Any ideas?

Error log is below.

The obvious answer would be that your printer isn't connected to COM3, but a different port. What port and speed is Pronterface connecting with? You can manually set those in Cura's prefs, so that it doesn't have to autodetect.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
