I am still interested in the X-controller, ready too buy actually. The mechanics of building this machine don't worry me, but I am not as well versed in the electrical side of things. So having all the components ready to go in one neat box is appealing. Plus this will be my first cnc machine, so this simpler the better at this point. I wonder if inventables will include the little plugs to put on your stepper motor wires that plug into the x controller?
I do agree about the EStop I would have liked the ability to relocate it, as I plan to mount the X controller upside down under my x carve table. I will either put an EStop on the Ac power going to the x controller or open the x controller and unplug the current EStop and run some wire out to an external EStop. In either case I have one of these I plan on using.
