I would like to hook-up two push button switches for my torch, one push button for up and one for down. I don't have any room in my input breakout board. I know I need another board and a second parallel port. Not so good for electrical, can some one help me on this?

If you are looking for external jog buttons;

You can use a usb device to send up and down button to mach3 with modbus. And just create a brain file for use the usb device's IO s as an z++/z-- jog input...

But If you want to use this inputs as a thc. There is a delay around 100ms in modbus with brains. You need a plugin to discount the delays.

Set up the THC function as emulated with Hotkeys.  If needed remote use a simple usb keypad that uses the same hotkeys as youset up for THC control.
