Thanks Kirk;
Everything above checks OK. All switches ON (UP, to the center of the board)
except for the forth, which is the A axis non servo (and it works).
The move command voltage shows in the ppmc.0.stepgen.nn.velocity.
Apparently this problem is really deep, or really sneaky (my vote is
sneaky).
