Cura stopped slicing

[Mjolinor 0]

I have been using Cura with my Wanhao Duplicator 3 since 14.03. I tend not to bother updating too often as it all seems to work extremely well for me but I will try new version as and when the desire hits me.

At some unknown time in the last few weeks I cannot get it to slice if I have the "Machine centre 0,0" ticked in machine settings. If I untick that then all works as it should but when I tick it then it will not slice.

If I run from teh command line I get a Python error so I am thinking that it is something else that I have installed or modified since I last used Cura. I have tried 14.02 - .04, they are all the same. I have to fix this or I am restricted to positioning things at the front left in Cura and having them print rear right on the machine.

Command line output:

Listening for engine communications on 49674

That should have said 15..02.1 to 15.04.3

Well I have trawled the internet and reinstalled all the software including Python and all it's bits and numpy, edited all the files that stood even the most remote chance of fixing it and nothing doing, still the same. This is my last hope, if I can't get a fix here then sadly and with much regret Cura and I will have to part and go our separate ways. A sad day indeed.

I'd suggest waiting a few weeks. The new Cura will be released then.

I wanted to try the beta versions but for Linux I can only find AMD ones, not Intel. Often a release is positively ancient before a Linux X86 is released.
