Re: g-code for my touch probe

Graham,

<Still>Interested? Yes.

Metric tooling a problem stateside? No.

Consider implementing your idea of a pcb top--or delrin--to the hub.
You could easily mill the hub as you did the body parts; and this
would allow you to have 3 appropriately sized and located slots for
the dowel pins.

Nice to see you considering publishing/ posting the details of your
probe. IMO it will be a valuable addition to the DIY-CNC community!

Ballendo

P.S. Were I starting from scratch--being stateside--I'd use 1/8"
balls and 1/8" drill blanks. 4-40 screws.

But .093 drill blanks and 3/32 balls wouldn't be any problem to
source, and 2-56 screws would be fine.
