It comes with its own gcode interpreter? I cant use that I already have an mpg with mach3 and I love the mill wizard. Less than a week goes by and there I am opening my brand new stepper controller. I see a $40 chinese knock off of the mk1 I think to myself thats what I need. I go bargain shopping without even looking at the plugins page. So here is the deal, I only have a laptop so I see I need a usb stepper controller.
