You can't do that, that pin name is already taken. You need a new, unique, chosen-by-you name for the HAL pin that belongs to the GUI button.

<text>"Home X"</text>

Bear in mind that this tag only sets the text that appears on the button, not the name of the hal pin....

net home-x halui.joint.0.home pyvcp.home-x

... So this won't work.

Andy,

You can actually have a pyvcp hal pin name the same as other pins as it evaluates out to pyvcp.halui.joint.0.home so it becomes unique and a valid pin even if it doesn't make sense to do so.

Ah, yes. Good point.

While we are at it, you can add things randomly to the INI file, and you will be able to access them in hal with [STANZA]ATTRIBUTE, but the rest of EMC2 will pay no attention.

And that is not mentioned anywhere that I know of yet...

Perhaps I ought to make sure that it is true first, then

I noticed in the hm2 configs but didn't think of it till now...
