GeeBake,
DeskCNC's control board works in concert with the software to provide the pulse trains, direction signals, and I/O functions. It has it's own on-board microprocessor to lighten the burden on the host PC. The CAM aspect of the software will function without the control board, but for machine movement control, the board is required. It is compatable with all step and direction input motor drivers. (Gecko's, Xylotex, IMService's servo drivers, etc)
