It's an STM32F103 for all that I know. EDIT: See this blog post https://tinkerfiddle.blogspot.com/2019/02/xvico-pioneer-x3-board-reverse.html

@oliof thank you, he is the main source of info on that board.
Here’s the results of testing all four stepper drivers.
X motor: .442 / .8 = 552.5 ma
Y motor: .389 / .8 = 486.25 ma
Z motor: .405 / .8 = 506.25 ma
E motor: .420 / .8 = 525 maInteresting that they’re all different.

@mac I wouldn't expect them to be all the same, and I would just set them all to 600mA in RRF.

@oliof if I could connect that Xvico board to rrf; that would be better than burning it to ashes, I guess.
