    Sir,

    What do you want the THC to do? If you need initial height sensing, it is somewhat complicated; if you just need auto height control during cutting, the system is simpler. I made such a system 18 years ago.

    Regards,
    Jack C.

    Jack,
    Your pics are very clear when enlarged. But the schematic cannot be viewed in detail, as enlarging it, just smudges it out. Do post a clearer pic of the schematic if you dont mind.
    Thanks

    Default THC

    I was unable to get a decent picture off this most recent post. Email me for a good JPEG.
