They need to advertise where DDG picks it up. But I'm so used to a direct electrical contact now that I probably will never go back to touch probes. You would laugh at my most used probe, its a 3/4" rod of teflon, with a hole bored in the end to accept a piece of 12 gauge copper wire which is glued in. A piece of stranded wire about 14 gauge, is striped, divided into two, straddles the 12 ga wire and is twisted at the far ends to get a grip and contact, drapped over something on the head so it doesn't crawl down the wire when I start the spindle. The 12 ga, while spinning, is a perfect circle of a size that doesn't care as long as its circle is smaller than the hole whose location I am probing for. The math in the 4 way probe routine returns the exact center of the hole which then becomes the xy touch off point with a .0002" max error plus the slop in the ball screws.
Plenty close enough for the girls I go with at my age. :o) Take care John Cheers, Gene Heskett. -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
