Then you might be able to write a Mach3 'Brain' to achieve what you want.
But only if the encoder talks to Mach3 and in this case they don't. The loop is closed at the drive and Mach never see's the encoder so that won't work.

Not sure if the drives will report encoder position thru the serial connection but suspect they will or could be made too.? In which case it may be possible to feed this to Mach3 then use a brain like Eddy suggests.?
