Awesome, thanks a lot for all the suggestions. I try to figure that out.
"machinehop5" : I tried the G91 incremental commands and it makes sense. I would not have access to the automated CAM functions in Filou as these use mostly G1-G3 commands. But for easy jobs and for my lathe this hint will be very helpful in the future, thanks.
" Heavy_Metal" & " mactec54" : I tried to use the G52 and G54 commands but my CAM software can`t handle them, so I cannot see the results in my simulation, this seems to risky to me. Now I see WinPC-NC also can handle these, but in a newer version than I have....
The Cimco simple-math-function editor is exactly what I imagined in my wildest dreams, but the software is quiet expensive. I will try the demo now, it surely has a lot of other things to offer.
"lucaswalker" Wow, thanks for that. I did all that and now have the Python script. I didn't find out, how to process my G-code with the script. I put it into another txt file and let the script run as you said, but nothing happened...
Can you give me a hint what I am doing wrong?
"You may need to manage I and J for arc centers if they are not defined as relative to starting point !" Luckily my program uses I and J relative to the start point. e.g.: N1 G2 X52.5 Y154 I-5 J0
thanks
