Here's the G-Code he used for that photo. You can see he's doing 1mm passes turning the rotary table 3 turns. His mechanics are such that it cuts air at the start and at the end of the spiral. The question I asked him which relates back to my own system is what does F300 indicate? X at 300 mm/min or the rotary table at 300 degrees per minute. Or is it both? Ie. F300 for the rotary axis is 300 degrees per minute while the X axis is 300 mm/min.
