I ordered my Makers Gear plastruder and one of your control boards today. One of the things I can't figure out is the speed. My Gcode has very high feed rates in the 7980 range which is 325 ipm. my mach3 is setup in inches and the g21 tells it to work in MM do I need to make a XML file for a MM machine and change my steppes per to stepes per MM.
Thanks
