I have tried CNC wrapper but on conversion the feed rates in A axis are way to slow
CNCWrapper does not alter feedrates. They are left unchanged.
Go to Toolpath Configuration and set "Use Radius for Feedrate"
Then set whatever the Z axis zero height is in "Rotation Radius" DRO, found on the Settings page.
If using the centre of rotation as Z zero, then put a very small number in that DRO, not zero. (zero will turn it off)
