I am thinking about
I like very much the closed loops, that would be awesome. I said it before but again, the trinamic chips are awesome too, and the level of configuration would be as far as i know unprecedented for reprap. I think this project did not received all the praise it should. Its a big leap forward. Now either i am too excited about these features because i think are long overdue for reprap, or others ppls are overlooking them - to be fair, but probably both.
3 inputs for incremental encoders (3 axis supporting closed loop control)Reprap is by all means 4 axes, where the extruder is the 4th dimension - and the most important one. So i think it makes sense to have 4 closed loops. Only 3 closed loops would be limited to applications like a milling head. Using closed loops means what i believe is named hybrid stepper, sort of speaking a stepper which is able to keep its current low and otherwise increase its own current only when its actually needed, sort of like a servo. This would be an awesome thing. The commercial drivers that do stuff like this are prohibitively expensive. So i think the feature is totally worth it - but at least 4th is required. But well, since the board has 5 steppers, me for one i would give loops to all of them.
