I'm not clear I know, sorry, but I'm not sure rollover works, last time I tried it did half turn, but I will retry...
I retry to explain with some code ("ang short rot on G0 checked"):
G0 Z10 A0 //will start at 0°
G0 A300 //goes to -60°
G1 Z5
G1 A0 //wanted to mill from 300 to 0 (-300° to mill) but just mill from -60° to 0° (+60°)
Is there a code to mill relatively, I mean instead of saying "go to 15°" or "go to 300°" , to say "go 50° more" or "go 10° less" ? THis way I should just modify the post processor to do what I want.
