I was impressed with the touchoff demonstration video on You-Tube which used a piece of circuit board (top side conductive) and a Mach 3 macro to zero an installed tool to the top of the workpiece. I poured over my Mach 2 pdf manual, but can't find the feature. I have the same button on my screen, but is this for something else, or am I missing something?

In the video, the operator simply clicked the mouse on a screen button marked "auto tool zero" and when the tool slowly came down it stopped dead at the surface, put 0.0000 on the DRO, then backed up to a safe Z height. Evidently it also adjusted the DRO for the thickness of the circuit board. Can I get this feature in Mach 2?

You should be able to do it. You'll need the Mach2 screen designer, though, to add the vb code to the button. you might be able to get it from the ftp site at www.machsupport.com

Instructions are here.

I also viewed the YouTube videos on the Auto Tool Zero. I am using Mach3 V3.0. When I select "Auto Tool Zero" in the status section I get "Not Yet Implemented" message. What do I do to enable? (You probably figured out I'm fairly new to Mach3). Also does anyone have details as to how to make the touch pad and how to hookup to Mach3?

Read through the other thread I linked to above.

Did you send me a message on YouTube? I have been trying answer but I keep getting an error.

Just go to the link that Gerry posted.

If it was not you then just disregard this. :D

Yes, sent them prior to looking in CNCZone. Your emails came thru on YouTube. Thanks for the reply.
