Here is a new tool for everyone (Mach3 so far) this was done by @HughesTooling He did the post processor changes and the .f3d file I just asked for it, all credit for this goes to Mark he the Man with the getup and go to do this.
attached is the post processor and demo file is here
http://a360.co/217rTWk this is for wrapping Y axis to A this post processor can be used to convert X or Y axis to A you just need to make sure radius correction is set to half diameter in the file the diameter is 50 so the correction is 25, and make sure the axis of rotation is set in tool paths under config in Mach3.
I have not tested this on a machine yet also your X, Y, Z and A axis zero's have to be set first before running it there are some small changes still to be done it will be reposted when done but it works and is useable.
any question ask here.
