Hey Zach - I've got a diff for you for driving the steppers with a SLA7026M. It redefines the "direction" and "step" pins to directly control the polarity of the coils. Also adds a "state" variable to the RepStepper class, to facilitate the correct stepping of the motors - which is a grey code, interestingly enough. Might be useful for a lot of people who have a different electronics settup. I've tested it as part of my G-Code firmware for the arduino, and it works fine.

I can't get your firmware (modified by my diff) to talk to the host software though. I'm getting errors like "Receive error, re-sending: Timeout receiving byte" and "Resend limit exceeded. Failing without reported error." It may be a hardware problem, as I had to disable hardware flow control in minicom to get it to actually send characters to the arduino. I'm not sure, but I don't think that's normal

Great to hear Zach.

Exactly how did you confirm it is 100% compatible? You tossing this term around or is there a software/printing testing series or something?

I say this... as sometimes I know there are people out here who get confused on the state of "it is 100% ready, proven" vs "experimental beta firmware release and I'm the only person who has tried this".

Good news, Zach & Steve. I'm looking forward to tr...

Good news, Zach & Steve. I'm looking forward to trying out the Arduino when I get back from LinuxConf.
