Robin,
I am new to the Forum but I have been reading your posts on different subjects.

I was just about to create a thread on what software is available to take DXF files from Autocad and make 2.5D parts.

I have just started the conversion (well I am collecting parts) of an X3 mill and because I am new to CNC work I am not sure what software would be best suited to what I need.

What are you writing the code in out of interest?
I will look forward to here how you are progressing.
John
