Quinn,

Thank you for speaking up! Good to know that my 'opinions' weren't
too far off the mark :-)

Agreed, but only because you said "a bit of". How do you get the 3D
data into HPGL (I don't mean file format, I mean what or who writes
the additional file parameters and commands for 3D use of your system.

Yes, I believe these are the 2 most develop-able parts of low cost
CNC.

Could you tell us a little more about how you achieve this?

I really enjoy seeing the results of you doing this... The idea of
several inexpensive machines SPECIFICALLY designed for each task...

Would you share with us your compunut anti-backlash design?

Finally, I can't speak for others, but I can say that I wanted to
purchase your program some time back, but without more complete info,
in light of the other choices, I did not. IMO, you will reap the
benefits if you will 'show' more of what I've asked about above.

Hope this helps.
