How do people "home" or "touch off" Z axis consistently?

I recently discovered Titans of CNC admittedly it is based around HASS but they do have some good videos of fundamentals

Thanks Dean. I've been trying watching a load of YouTube to try and bring myself up to speed on all things CNC. I've not heard of that channel though but will check them out. Thanks

So probably a stupid question with an obvious answer, but I can't seem to piece together what I'm trying to do.

I have a similar touch-plate, minus the button. I'd like to be able to call the routine using a keyboard shortcut (something like F3 to kick off the probe move to touch-plate) vs pressing a button on the touch-plate and feeding an input. How does one easily do this without having to eat up a bunch of screen real estate with the PyVCP?

If it matters, I'm on 2.9 using axis with a X Y Z setup. The input pin (13) would be shared with a tool length probe button.

I think I'm just trying to make something way more difficult than it is.

Thanks

I originally added a button to the Axis screen to start the process. The button is just way more convenient. I would think you would be able to do a keyboard shortcut but I don't know how off hand.

Thanks for the quick response. I'll keep digging.

It's a lot easier to call a subroutine with a digital input than with a keyboard shortcut (oddly enough)

There might be the beginning of an answer here: askubuntu.com/questions/1202265/start-py...th-keyboard-shortcut

If you can get a keyboard shortcut to run _any_ python script then you are half way there. Then the script could MDI some G-code through the LinuxCNC Python interface.

Cool, I think I can work with that. I hadn't even considered it. I'm on Mint 19 so it should be possible.

Thanks
