[Cura 2.3 Beta Awesomeness and Some Issues]

 

 So, it looks like slicing fails when the "machine center is zero" is checked.

 

I just tried this from source and I couldn't reproduce it. Could mean that someone already fixed it. Could you also give me the logs? That way I can verify if your issue is actually solved.

 

Here is a relevant line from the log:

2016-09-02 22:06:29,601 - DEBUG - UM/Backend/Backend.pyc (_backendLog [88]): [backend] Assertion failed: (false && "We should have returned already before here!"), function insert, file /Users/Ultimaker/build/2.3/build/CuraEngine-prefix/src/CuraEngine/src/utils/SparseLineGrid.h, line 112.

 So, it looks like slicing fails when the "machine center is zero" is checked.

 

I just tried this from source and I couldn't reproduce it. Could mean that someone already fixed it. Could you also give me the logs? That way I can verify if your issue is actually solved.

 

[Cura 2.3 Beta Awesomeness and Some Issues]

I was excited to see the features of 2.3 and downloaded it.  Loved the custom machine setting.  Used it to set it up for my delta and checked the setting "machine center is zero".  Then when I loaded a model, the slicing would just hang part way.  When I tried unchecking the "machine center is zero" and tried slicing, it worked.  So, it looks like slicing fails when the "machine center is zero" is checked.

Thanks,
