lezdep , take a look there:
.. I did a few test on cnc at work with both script and the cnc/mach3 did what it should , no weird code where add .I`ve only tested 3D .
I do not write or even understand python script and the cnc world is pretty new to me... just to let you know that I wont be able to help your precious work untill i do my homework and study a bit more. Testing is all i could do ...for now! Maybe you got a link to someplace where I could start learning python and eventualy help! As I am a bit mixed up in my poor knowledge of cnc ,blender terms & function , I just dont want to take your time to teach those to the newbie I am!!! so I will be back when i will be shure
that I got precise terms for precise questions!!
Time is precious for everybody .
Keep it alive!!!
