I want to build a 3-axis cnc machine. The thing is I have no background in electronics or mechanics whatsoever. But at this point and after reading a lot of threads and related sites I can say I now know a little bit of everything.
Now I´m trying to figure out how to assemble all the electronics together. I have some NMB PM55L-048 steppers (24v, 800mA). I know this is not the best choice but for now it´s the only one.
For the driver I choose the L297 Unipolar design from PMinMO (Thanks to Phil) and for the interface, aslo from Phil a 4-axis BOB.
Links to both boards:

Few questions:
* the logics of the driver board feeds from the 5v through the IDC (from the interface) or directly from the PSU through X4 wago terminals?
* Is the motor connection (5 wires) ok?

Is that correct?! I something missing?
Thoughts and comments are very welcome!
