Anyone know someone with experience of setting up Mach3 or Mach4 with a Smoothstepper? I hav a terrific but small 3 / 4 axis milling machine built for me by the legendary CNC builder Jason Jack in NZ and he has been really helpful in remotely configuring it and writing the Gcode but I'd like to find a 'cnc geek' in London who I can call on sometimes to tweak it and/or write Gcode from my CAD files for a modest fee.
