Cura won't begin slicing

[Dendrowen 0]

Hello there,

I'm using Cura for my HyperCube printer for a couple of months now and am currently on version 2.6.1. For Ubuntu 2.7 isn't out yet.

Until yesterday I could use it with ease but now suddenly it won't start slicing anymore. The steps I take:

- Open Cura

- Load model

- Change some settings

Now cura says it's busy "slicing..." but nothing happens. It's a small model so it shouldn't take more than a couple of seconds but I've been waiting for 5 min now and the progress bar just remains at 0%.

Things I've tried:

- Reboot Cura

- Reboot system

- Reinstall Cura

- Setting slicing from automatic to manual

I've included the DEBUG log from the moment I start slicing. If you need more let me know please.

Cura-Engine and some other parts are in version 2.7, cura itself remains in 2.6 for the moment. I think this two versions are the problem.

Yesterday i had the same problem, and today cura does not even start...

Use the AppImage instead of the PPA and you will no longer have upgrading issues like this.
