If you are using Mach3 to control your "A" axis (indexer) then by entering the radius of the material in the "A" box of Rotation Radius on the "Settings" tab all the feed rates work correctly. This also enhances the preview screens in Mach3 so you can actually see the part you are making.
The thing you have to remember to do is manually enter the radius of the material in this box each time you do a project. Since I am getting older I could see a time when I would forget this step and ruin a piece of material or break a bit. I wanted this operation to be automatic when the tool path was loaded into Mach3 so I modified the Vectric post processor and added a Macro to Mach3.
Using "Mach2_3_Wrap_Y2A_ATC_inch.pp" I added some code so Mach3 could read the diameter of the material and named it "Rays Wrap YtoA.pp" and saved it in the post processor folder.
In Mach3 I wrote a macro to read the diameter of the material, divide the diameter by 2 to get the radius, and write this number to the "A" box of Rotation Radius on the "Settings" tab.
Now each time you run a tool path the radius is entered automatically you don't have to remember to do it.
Paste "Rays Wrap YtoA.pp in the postp folder of either V Carve Pro or Aspire.
Paste "M1100.m1s " in "C:\Mach3\macros\mach3mill\" . If you have named your version of Mach3 something different than "mach3mill" then substitute that name in the path above.
I am using the Mach3 version R3.043.066 which I believe is the latest version. The radius compensation feature did not work properly in some of the older versions of Mach3 so get the new version first.
If you want a pp for wrapping X to A or in metric just give a shout.
