You can start with this:

or a cubloc micro through modbus:

I use a cubloc works nice with mach3 doing analogue spindle speed and feed overrides.

thanks for the links, but they are ready to use, there is no schematic diagram, i want to build one, i think pic18f4550 microcontroller will be fine, but will be waste of time to write new software, if somebody allready done this, so Im looking for open source project or something where i can use
