Alright thanks. I'll look into that. I don't think it's a spelling mistake. I suspect that it's two outputs connected to one input since the pendant I have has a button that sends all three axis to home.
Based on http://www.linuxcnc.org/docs/2.5/html/hal/basic_hal.html The net signal name "remote-rapid-to-home" Is connected to the input pin "halui.mdi-command-00" defined in the section [HALUI] MDI_COMMAND = G0 X0 Y0 Z0 The value of pyvcp.rapid-to-home comes from the screen button I created in the xml file. (it's on the screen and shows motion when I click on it). Now I forgot to mention that there's a included file layout2.inc which I've attached. I just noticed that it also has a [HALUI] section and has the same MDI command. And under [XHC_HB04_BUTTONS] goto-zero = halui.mdi-command-00 So it looks like there are two outputs both connected to the input halui.mdi-command-00 Does that make sense? Is that why there's an error? I'm assuming it must be possible to have a screen button and something else cause motion because the Up arrow key on the keyboard, the MPG on the Pendant and the Axis Screen button all move the Y axis. So I'm a tad confused.
