Many thanks Irving for your advice. I had a visit from John S today and within literally 10mins had the machine set up and configured correctly and again many many thanks to yourself and John for sound knowledgable advice,now I am safe in knowing that the machine will cut a given dimension and know its correct. All I have to do now is work out and learn going from CUT 2D to Mach and start producing some stuff, can't wait!!!!!!!
