I have a old Dyna CNC machine i use for routing wood. It currently uses gecko 320's, 3 of them to run 3 servo's with a torch height controller in line using two parallel ports. I would like to remove the THC and move to a Ethernet control instead of a parallel port. So what board would be best here? i was thinking PMDX 126 with a 107 on it? If this is a good route what voltage do i need to supply the board with? Thank you for any help in this!
