Arcade Button Emergency Stop

[mikkojay]

Hello All,
I just got done throwing together an experimental XYZ machine using Gecko g320 drives. I had some leftover arcade buttons from a MAME machine I made a few years ago, so I used a red & green button, a Radio Shack project box, an old keyboard cable, and a couple components to make an emergency stop button box. Hopefully the pictures will speak for themselves. When powered up, both the red and green LED illuminate. You press the green button for a couple seconds (sends 5v to reset) and the red light goes out / drives reset. Pressing the red button (sends reset to gnd) or a real fault causes the red LED to illuminate. The whole rig was inexpensive to make and works really well.
Thanks, Mike

I like your idea. Where did you get the red and green buttons?

ebay, my favorite place!
Do a search on "arcade buttons" and you will find a bunch of them.
The pnp transistor can be found at Radio Shack.
Thanks, Mike

Awesome, and simple! I'll be doing the exact same thing, as I have TONS of those buttons/switches laying around (also from a controller I built).

They make a keyboard encoder that you could hook up the buttons (or even a joystick) for controlling all manual machine movements.
I have one of their I-Pac encoders for my Virtua Fighter 2 cabinet that I converted to MAME (Multi Arcade Machine Emulator). These are perfect for a CNC because the inputs are fully programmable.
When I finish my router, this is the route I will use for my control.
