Re: Proxxon mill and touch probe

Hi Graham -

No, I never built one. We had had a long thread on what
commercial digitizers must look like inside, and I just fleshed
out some ideas that others had explained. If the design works, it
should be pretty inexpensive to duplicate, even in small
quantities. A custom PCB for the contacts, debounce circuitry,
and maybe an LED indicator, would finish off a nice product. I
wouldn't mind one myself. I'd be happy to produce drawings of the
parts in exchange for components.

BTW, what software are you using for digitizing?

Ah hah! You did the 3D model. Did you ever build one yourself?

I just need 6, 2mm ballbearings and I am ready to roll, no pun
intended. Please email me some if you have any :)

I reckon if I get results aything like with my Proxxon and delrin
then you guys with your servo systems and fancy steel should be
able
to make something that works really well!

I recently saw a touch probe that used an LED, two lenses and a
differential photodiode, very clever and possibly buildable from
the
optical side of things. You still need nice tilt mech though.

Cheers,

Graham
