CNC Pendant with 100 MPG

[Smiler]

Just found this via kipper: http://cgi.ebay.com.hk/ws/eBayISAPI....1&category=633

Surly we can make these for allot less ? is there anything special inside these i may not know about ?

Zapp also wants: http://www.slidesandballscrews.com/i...2708d04a19410a

So all that is really needed is a nice case to mount the hand wheel and switches in or is there somthing special inside these units ?

That's like mine!!.

Nothing special at all Lee. They wire direct to your BOB (+5v, GND, and two inputs) then tell Mach which inputs and that it is an MPG, simple as that. The only problem comes if you are running out of ports on your BOB in which case you could just add a second parallel port and a BOB for a few quid. You will also need a couple of switches to tell Mach which axis is selected. I've modded mine with extra switches for cycle start, stop, Step or continuous jog by using the wires from the 5th and 6th axis inside the case (which I will never use)

Probably be able to make one for less than 70 quid all in, maybe even less.

Got to say that the one I have is very well built and works beautifully.
