Hi Ben,
Here’s a note Jeff Kerr, I’m sure others are interested also.

Thanks, Mike! Yes, it would be really nice if Pololu either integrated this feature into their standard firmware, or else offered it as an alternative that could be loaded using their bootloader. Not many people are willing or able to completely re-flash their Tic firmware. I’ve talked to them about this option, but it might take a few customers like yourself expressing interest for them to offer it.
Wow, that’s an amazing robot arm you’ve created!! Congrats!! I’m using the Tic-500 to control a macro photographic setup for imaging small subjects (chips for example). I understand what the multi-axis coordination requires, and ended up doing such in Python running on a Raspberry Pi. Your solution is much better, but if you follow the threads below I’m not a software or computer person, and EE (design chips)… so reprogramming the Tic not going to happen for me! I even asked Pololu about putting 3 Tic-500 equivalents on a single PCB and having 3 USB connectors, but that wasn’t a great idea unless they used a single USB which meant they had to create the new code like you’ve done. You might want to ask Ben about this, maybe they could use your code?
I had thought of using an Arduino, but decided on the Raspberry Pi since it seemed easier to work with to develop the code, and my total lack of software & computer skills.
Anyway, what you’ve created is very impressive, so hats off
Best,
Mike
