What is everybody using for i/o boards to interface a control panel full of buttons and switches to mach3. I've been using Pokeys usb for many years but I'm really getting tired of the problems. (very susceptible to noise and randomly stops working.) Recently had it open the collet mid operation with a bar feeder. Bad things happen.

The PoKeys is great.  Especially because the plugin has all the built-in functions that you can think of for a panel.  The downside is that the I/Os go pretty much directly to the pins of the microcontroller, so you really have to know what you are doing to connect all the pins and functions.  We used to make and support all kinds of I/O boards for the Pokeys boards, but stopped producing them as the demand was low.
