That's realy interesting but it's strongly NC oriented. I can control my
3d-printer via USB by sending S3G commands (sailfish fimrware) but
that's too specific bound to the hardware and to the XYZ thinking.

What I'm dreaming of is a controller which allows defining a step input
(including speed and maybe acceleration paramaters) and the motor moves
to the position without any additional input. The final positition is
sent back or confirmed on request via the used interface.
Think of an axis contorl of a robot arm. The combination of several such
modules can be controlled by a raspberry because the hardware part and
the real time components are not important on that level. As example it
I would be very simple add a GUI for programming, etc.

Is there a cheap solution known?
