Greig,

There are 2 post varialbes that you can use instead of the NC_FEED$ command. They are NC_TAP_PITCHI$ and NC_TAP_PITCHD$...the first one will give you per minute feedrate and the second will give you per rev feedrate. I think you are looking for the NC_TAP_PITCHI$. You might need to put a "F"; in front of it because I am not sure of the formated word has a prefix...try it and see.
