I'm having problems making a post processor for a :-

Centroid CNC4-B24-MD3

The main problem is applying tool compensation G41/G42
Most controllers if you do the following will apply comp OK

Example 12mm Dia tool
G0 X11 Y25        (tool moves to x11 y25)
G1 G41 X0 Y25     (tool moves to x-6 y25)
G1 Y50            (tool moves up y axis)


If I do the same with the Centroid

G0 X11 Y25        (tool moves to x11 y25)
G1 G41 X0 Y25     (tool moves to x-6 y31)  ***DIFFERENT***
G1 Y50            (tool moves up y axis)

Has anybody solved this or does anybody have a post for a Centroid CNC4?
