Greetings; Has anyone drawn up a probe of the sort one could mount in the spindle collet, hook up to emc so that when contact has been achieved, emc records the location?
And, assuming this has been done, has the scanner routine to do this already been written too? I'm thinking in terms of the engraving done on a bolt rifles floor plate, or trigger guard, so that if an interesting pattern could be scanned with potrace, and then the z axis treatment added so as to carve, say with a small diamond burr moving at call me next week speeds, to a consistent depth of say .005", the pattern obtained with potrace, but on a curved surface such as the bottom of a trigger guard or floor plate. But I'd need to be able to probe the contour of the item, and do it without doing any preliminary damage to the blueing, which is not a very good electrical contact surface. So I'm thinking in terms of a guided needle whose upper end can be set against a single button of a conductive elastomer keyboard switch, the effect of which would be rather like a potentiometer as the pressure increases, and we could trip and stop the z axis descent when a logic 0 was detected, record all 3 axis's positions, then reverse the z drive, move to the next position .005 away in the scan, and repeat. It seems like we ought to be able to do that if the contact pressure sensor is already a working item. Anybody care to share insights/drawings for such a beast/tool? -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
