The BeBoPr++ layout and specs look nice. I too am searching for
purchase options.
I'm building a small XY laser engraver before building a Delta
possibly a Kossel like Brandon Heller with the modified sled to ride
on the rails combined with Spectra Line drive or a 3DR(again wanting
rail sleds and Spectra line drive). I'm picking up a
RAMPS/Ardruino/Polulo/LCD kit to eventually move to the engraver with
the BBB/BeBoPr++ to the delta system. No doubt when shown at the local
3D Printer Meetup there will be lots of interest in BBB/BeBoPr++ from
the locals.

Doug,
The BeBoPr++ will be available for purchase soon (about 3 weeks from
now) and at a great price ! I don't use a pre-ordering system, I only
start selling when real boards are available. Send a mail to
[email protected] and I'll notify you as soon as I have stock.
For laser engraving you can use the 4th axis to pulse the laser
synchronous with the movement of the other axes. This way you get even
power distribution during acceleration and deceleration. Pulse duration
(power) is a parameter you can change by software in between moves.
Cheers,
