hello everyone. i have a really simple question about the sieg kx3 cnc mill. Does it come with everything it needs to be cnc, and just needs the software and the computer? i think it comes with the stepper controller, psu, and all the other electronics, but i just want to make sure. I don't want to buy it and realize that i'm missing something. so i just plug in the sieg kx3 to the power outlet, and the parallel port to the pc, install software, make some gcode and let it run? or do i have to solder stuff, buy components, fabricate this and that, etc?
