Hi,

  I am new to the list, would like to see what is needed to build a CNC
machine.
  We have bought a 3 axis platform, with steppers, can replace them to servo
with encoder id needed.

  We have some experience with micro controllers, and likely to use some PIC
based controller,
in these case the close loop is done at the controller end, can we use
UBS/RS232 to communicate
to the controllers, ans using the EMC2 as the GCode interrupter?

  Or we need to buy some hardware to communicate with the controller?
