    Well, I sort of answered my own question with additional reading of Alden’s TinyG Communications Programming. Very humbling. I don’t know that my programming skills are up to the level to allow me to take advantage of the extensive programmatic interface.

    Can anyone point me to any examples somewhere I can at least read through to get an idea just how complex this approach would really be?

    Humbly,

    I know this is a year old, but can you just confirm that you’re hooking these motors up as bipolar-parallel?

    I have been using the KL23H276-30-8B, for 282 oz-in at 2.1A in bipolar-series wiring.

    If you’re able to use the KL23H286-20-8B’s in bipolar-parallel, that seems like a bit more bang for the buck, but also pushing the current limits of the drivers. Am I missing something?

    Thank you very much Alden. That gives me a much better notion of what I’d need to change. I had read through system.h and stepper.c, but hadn’t dived into the settings header files. Now I see where each machine’s defaults are setup and it makes more sense.

    I think I’ll go down the “plain vanilla” path first, and make sure I have a more generic working system, before branching out into the wilderness.

    I am right on the edge of trying to build a TinyG based system, and have also been pondering options to set it up without a computer dedicated to it, and some simple UI option. I had to go look up the Chumby One, as I’m not in the small intersection.

    That said, I was thinking of an Arduino with an SD card shield, to load g-code, and an even simpler UI via and an LCD keypad arrangement. I was also assuming jog/homing, status line, and file selection, all accessed via an ATM-like UI.

    I understand using the Chumby because you have it, but was there some other reason you dismissed any sort of Arduino-based option?
