SOLVED Ultimaker Cura 3.1 crashes when connecting to UM3E

[SolarEcoProjects 1]

Hi,

II completely removed Cura from my mac before upgrading to 3.1. I had to do this to get Cura to run in te first place.

But when I try to connect to my UM3E (which is running the latest firmware) the software crashes.

Has anyone any idea how I can fix this?

What version of OS X are you running? Do you by chance use a proxy?

Here's a similar sounding report on github:

I'm running OS X 10.13.1 (17B1003), and I'm not using any proxy.

I am trying the solutions mentioned on GitHub, but so far no luck.

Any anti-virus applications (that act like a proxy to monitor incoming/outgoing traffic)?

I have Bullguard running, but I have the same result when I stop it.

Might the logs give some insight to you?

I just tried installing Cura on an iMac (same OS version). I also just updated both to 10.13.2.

On the iMac Cura works just fine, but on my macbook it keeps crashing when I try to connect to my UM3E.

Are you using the Apple Thunderbolt Ethernet interface?

Do you have 'Auto Proxy detection' turned on in your network settings?

You made my day!

This setting was activated on my MacBook for the Thunderbold Ethernet interface. After disabling it, Cura no longer crashes.

 

Thanks for pointing this out!

I am not using the Thunderbolt Ethernet interface at both of my macs.

But, the proxy detection was turned on, I am curious if this works with me when I get home.

This is a bug in Qt (a library which we use), once this is fixed we will update to that version of Qt.
