cool, thank you.
was this Linuxcnc ( gcode) or Hal ?
I think Hal can do a lot for animatronics and multimedia.

Sorry but, what do you mean by that?
We can move mechanisms with Hal, without Gcode, without LinuxCNC.
Hal can simply make motors move and use encoders and PIDs without
involving Gcode or Linuxcnc.
You could have hundreds of motors moving, while linuxcnc can have 9
xyzabcuvw (usually)
You can do linear circular helical and more interpolations in python and
have hal to interface your hardware.
Your flying ball could be accomplished in another way, thats all.
This setup was made by 4 joints (wires) and my kinematic module. A
three-axis-joystick was used to jog,home and set jog speed, and a gcode path
was generated by a software I've done in Processing.
ah! processing and hal is exciting.
A wonderful mesa 7i92 was used to send differential step/dir over a max lenght
of 220mt cat6 rj45 twisted-pair cable without problem. lines where terminated
with 100ohm resistor (without those i had problems..) directly on the drivers,
which accepted differential input.
oh i remember that conversation a bit. thats a loooong wire!
for the future I have to find a way to close the loop in a different way,
because with those hybrid drivers, if one gets alarmed, the system continues to
move until i stop it.
maybe bringing an ethernet mesa card to every winch?
I wanted to really thank you all for the help I've received in these years from
this community, that brought me to this point.
Ciao,
Davide D'Angelo.
thank you for your work
