Is it possible to use a switch on the cnc table that makes the machine go to park?

And set zero?

I am planning on making a jogging keyboard with switches for all the axes, start, stop and if possible go to park and srt zero.

You can make user defined script that does what you want and assign shortcut to it. All inputs can be used for shortcuts.

How would that work? You are talking about doing this on the pc/software side with usb/Bluetooth?

I would like to do this on the hardware side with inputs directly to the mk3.

You can define all eight Mk3 inputs to execute any command you want. This is set in "Settings/Shortcuts". You can also use it to execute user defined scripts.
Jogging works same way except that it uses its own jog inputs.

Without PC controller is not usable anyway.

I solved like this:

I bourgt an Teensy 3.2 like that: https://www.antratek.de/teensy-3-2-p...SABEgI7NPD_BwE
Then i programmed some functions to the different outputs.
e.g. Push button on pin 14 send /430 (maybee homing)
Then i build a remotecontrol with the most used functions uns put some buttons in.
I wired the buttons to the pins on teensy and wired teensy to usb.
in the TNG -> shortcuts i set the commands from remotecontrol (teensy) to MDI.

It works like that:
Press button "homing" on remote, teensy send command "/430" to MDI.
MDI knows "430" is set to homing.
thats it.

Maybee i can send some pictures if you want.

Instead to MDI you can also send keyboard shortcuts. It might be more convenient for some commands.
