The non ultimaker profiles are not tested or created by us

Understood. However, the issue happened with every profile I tried including the built in Ultimaker ones.


Regardless, the problem seems to be related to Cura being somehow internally disconnected from its slicing engine when connected to NordVPN with split tunneling enabled.




I'm waiting to hear why a VPN that only controls traffic to the internet will break Cura. Is Cura talking to the internet to slice?


As an aside, this also was causing my inability to log into my account via the app. I'd ALMOST get that one since it's relying on the Ultimaker portal.


If you have any insights as to why this breaks Cura, I'd like to know!

PS: I can't even get to this forum when ion VPN which is also disturbing. Cloudfront blocks my access.

    I have the latest version of Cura. I just built a 3DP. When I import the Benchy model in Cura and set it up and click on the Blue Slicing Button on bottom right, it shows loading, but it doesn't progress. For 2 hrs straight, I waited, it didn't progress.

    It shouldn't take that long. Please help.


    You show no network connection in your systray. Check that and make sure you have allowed Cura through the Windows firewall and turn off the VPN if you are running it to see if that helps.

    Cura isn't talking to the internet to slice, but it is strying to create a local socket. So it could be that nordVPN is somehow interfering with that.

    When I installed Cura 4.8 it sliced one time then stopped. I could not get it to slice so I uninstalled it then installed it, it sliced. After I set things up to my regular settings it stopped again. At this point I figured it may be my settings. I have had problems with retract stopping mid print so I normally just enter as many 9's as it will take and move on. I went back to my retract settings and backed out one 9 and it sliced. I put the extra 9 back in and it stopped.


    At this time Cura is working fine on Windows 10 pro with this retract setting.

    One my Imac I can max out the retract # with no issues.

    Try unticking Enable Bridge Settings option.  I have the same symptoms with that enabled.
