Re: Lighted edge finder

Hugh,

You could do this. With any type of "programmed" probing, be sure
your probe has overtravel capability! Unless you are moving VERY
slowly, it is pretty likely you will need it.

Ray(I think) has added use of the probing functions to the EMC manual
located at: http://www.linuxcnc.org

MaxNC and Larken LCAM support probing directly. It can easily be
implemented with IndexerLPT,MicroKinetics InStep(motion library, you
have to use their card ~200 bucks)

If you want to get innovative(or just crazy) you can use the "homing
routine" of most packages "creatively". Bring out a 2nd switch
(parallel or series, depending on the setup), put it in an
appropriate place to do what you want, and hit the home axis key. I
have used this approach to figure tool compensation and part location.

Hope this helps.

<snip>Now, could one bring the wires out, treat them as a
contact switch, and run a signal from them into a parallel
port? Then the trick would be for the software to monitor
this signal and use it for probing. What do you think. :-)

I've read that EMC now has probing? However, I have no
idea how the probe is connected and monitored. Is anyone
familiar with this function of EMC? Do any other packages
support probing?

Thanks.
