Hi When Mark first built the Ox he used a 3 Axis Driver Board coupled with an Arduino to drive the Nemas. I've got 2 of those, but now the 'Black Box' has arrived on the scene I thought I'd buy one for my 3rd Ox build. I just wondered before I buy it if it will actually work with the Ox. I can't see any reason why it shouldn't but just to be sure. Thanks a lot. Fabian.
