For the operations I need it works and I see no reason right now to go back to Fusion.
Hello, thank you for the reply. Yes, agree! Reading my post again I see your point. What I actually wanted to say: “I made no progress so far and that I had no chance to get usable G-code!” I am not trying to troll. I should have been more clear with the wording. (sorry for that!)
Yes, specific problems 
a) I cannot get even the simplest movement out of the Fanuc controller

b) I have to admit, that I do not even have a slight idea where to start fixing it by myself.
Greetings Timo
Can you post a sample that works with your fanuc controller?
%
;
1003.nc (FREECAD-FILENAME-GOES-HERE, JOB-NAME-GOES-HERE)
sorry I don’t know about the fanuc controller but this looks a bit odd to me, % stands for what? ; is supposed to be a comment 1003.nc (…) filename and comment? maybe the filename should be in the comment line after ;…
well just post a workable example for your machine and someone can double check the initial handshake difference. The G-Code itself will be the same I assume.
Hello,
Thank you for interest.
In the other thread, that I linked before I tried to describe the issues that I could locate so far.
The “%” is required to be at the beginning of a program. That is one thing that is not wrong.
