General Mach Discussion / Re: Set Z to zero automatically?Auto tool zero questions

Greg,

Thanks for clarifying some of this for me - I think I'm close. I have a pin assigned to "Probe", and I can see it toggle an LED state in the Diagnostics screen when I ground the touch pad. However, its state (i.e., grounded or not) doesn't affect the running of the macro, which runs to the limit of it's travel, retracts, and displays the "z axis now zeroed" message.

I guess I don't understand what in the macro tells it which pin is hooked up to the probe...

Again, my thanks for the help.

Thanks to you all you guys, I've got a custom screen, macro that seems to work, and a plate fabricated. My problem(?) is the actual wiring to Bob Campbell's excellent BOB. There doesn't seem to be a probe or spare input, and I think I'd like to use the Z limit switch input for the probe. Am I right that I need to modify my config(.xml) file to do this? Or am I missing something obvious?

Any suggestions would be appreciated.
