Hi Ricky
I'm still not to sure what your setup looks like but from what I understand you're g-code is not going to work. When working with rotary axis in Mach, your toolpath won't look like the profile as suppose to 2 or 3 axis linear moves where the toolpath basically simulates the profile you want to cut, instead you will get a toolpath on the screen, then another after the A axis has rotated but on the same xy plane
The toolpath window will not rotate the plane after each rotary movement. What will happen with your toolpath is that you will have the same xyz movements copied and pasted, it sounds a bit confusing I know. I need to draw this to give you exact movements, say you start x0 y0, then you will go to where you want to plunge. Z comes down then you do a cut like in your case -65 on x, now remember, with your turntable being square, after a 90 degree turn, where you have stopped at x-65 will now change to x0 y-65. This will not give you 100mm rad corners though but hopefulle you can see how much changes after the 90 degree turn. Give me a day or two then I will send you a sample g-code you can try.
Cheers
