Hi Jesper,

I opened your moi file and what I can say now is that you better use real 2D, that means only use edges and not faces.

make sure that the unit system is set to mm or cm in the MoI options dialog, otherwise the G code generator will not be able to determine the size.



I selected the top face of your spoil board, copied it, then deleted the whole and pasted just the top face. then I selected just the edges from the face, copied it, deleted the whole and pasted just the edges. then I joined the whole, to make sure to have continuous lines.

this gives a 2D drawing which can be exported like this:



this yields a 2D dxf file which I trust to open without problems in Estlcam, I made an identical file for my machine last year.
