Auto touch off?

[FozzTexx]

Does anyone know of a guide for setting up an auto touch off for the Z-axis? I've done lots of searching and I've seen people say they've done it and people say they are going to write a guide, but nothing out there really says what files need to be modified and what lines need to be added where.

I'd also love to be able to auto touch off on the x&y axis like I've seen in some videos where they use a copper tube to find the center.

Ok, so I'm trying to figure out a procedure to do the auto touch off. I haven't made it very far.

It seems like the first step is to add one of those virtual control panels on the side of Axis so I can click a button to do it. I thought a good button to start with would be a "home" button to simple do g0x0y0z0.

To setup the button requires use of pyvcp, creating an xml file, and adding a line to the .ini file.

Here is my home.xml file:

PHP Code:

<pyvcp>
  <button>
    <halpin>"home-button"</halpin>
    <text>"Home"</text>
  </button>
</pyvcp> 


In the .ini file you add a line to the [DISPLAY] section:

PHP Code:

PYVCP = home.xml 


When you load Axis you'll now get a Home button on the right side. Unfortunately it won't do anything. Somehow you need to connect a "pin" to something to execute the g-code.
