Well, the Arduinos are easier to purchase (click-and-buy on eBay), but I'm really thinking more about the folks approaching LinuxCNC from the 3D printing / Desktop CNC world, which seems to revolve around stepper motors, Polou microstep drivers, and Arduinos. I figure a pretty good chunk of folks who would be interested would already have the Arduino anyway. Obviously if you've got a serious machine to control, the money for Mesa or similar hardware is very well spent. > I think you would rapidly run out of IO pins unless you were going > to have a realtime serial interface.

The Mesa boards definitely win out on I/O count, though. - -- Charles Steinkuehler char...@steinkuehler.net -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk+2TEIACgkQLywbqEHdNFy26gCgxlvsIdp4GxYHFcrwxr67zJVe O2UAn1OEIOhr9TAAmPNTguuZmMeA7vWW =gEfM -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
