you can do this using equations in Mach3 as per:

http://www.indoor.flyer.co.uk/kinematics.htm

The equations would convert the primary axes x and y not connected to
motors to two slave axes, one linear one rotary. Or you can define
x,y in terms of themselves, its all covered. The equations would be
very simple, angle from trig, distance from pythagorus.
