How does a touch probe compare with a laser type probe? I am assuming the laser type has a faster scanning capability and is able to scan soft things likes plants/flowers used to machine wooden decorated things.
Does the proximity switch (very inexpensive) probe really work? I am thinking about using a piece of rod with an inexpensive proximity switch attached to the end and a wire from the switch to the parallel port. Is this all that is required to get it to work? What kind of proximity switches? Any www sites of example switches? How about a momentary switch from radio shack? |
