I've heard so many good things about Trinamic drivers, but never had a good opportunity to use them! I'll be fixing up a friend's 3018 generic soon, might be a good time to give them a try. Changing current on the fly is a killer feature!

Nice, we use CNC microscopes at work for automated feature dimension measurements, they're incredibly useful for validating milled parts and inspecting wear patterns over time.

Thanks for the info, I'm going to have to upgrade again soon it sounds like!
