[Bug] Cura 3.6.0 Hangs at launch

Recommended Posts

I've been using Cura for a little while, 


I ran into an issue recently where the tool just stopped running. It would attempt to launch, show the splash image then an empty window that would just hang. 


Tried restarting, uninstalling, reinstalling, nothing worked. 


Luckily I found a way to fix it...


I have a laptop dock with 2 attached monitors. The only different thing (to my knowledge) was I used one of the attached monitors for the first time and it kept trying to launch on that secondary screen. Which It was having trouble doing.


I unlplugged the dock and used just with the screen on the laptop. And it opened up! 


I attached the log of a clean install of cura showing the symptom below if it helps resolve the bug permanently.


Hope that helps someone who might've had the same issue I did. It might be display related, unplug all secondary monitors and see if that helps.

Make sure Cura is on your primary screen when you close it. 


This is the work-around I use right now but it's pretty limiting. Especially now that I have some reliable triggers that will cause it to crash on the other screen (on creation of a context menu, selecting between model view and layer view). 


Whats the best way to get this in front of one of the developers to take a look at?

It helps if you are a client that's about to buy 100 Ultimaker printers 😉 More seriously though, it has been an issue for a long time, and it never got enough traction to get it fixed unfortunately. I don't know who's the "product owner" of Cura these days. The product owner has a large say in what gets fixed and what will remain open for the foreseeable future because there is too much to do. You could chime in here: https://github.com/Ultimaker/Cura/issues/4427


As another, more permanent workaround, it should be possible to write a plugin that forces Cura to always start on the primary screen. Thing is I already have 10 plugins to maintain and update between versions...

    • "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.
