CNC Interface circuit

If we look for the Web will find many options to build a system of drivers CNC, in my case I like the modular format, where on the one hand we have the drivers, who control the engines as the signals it receives from the PC, and the interface, that actually does more than communicate with the PC drivers, some people in one arm around plate, even omitting the smooth interface, is a matter of taste and practicality.

In this case then we will have interface on the one hand and on the other drivers, being the real objective of isolating the parallel port interface of the PC drivers, in this case using floodgates kind of buffers (74HC244), surely many will say it would do better with opto-isolator, may be so, but the availability of optos quick response here in arg is not very good, or are very expensive, besides taking care using minimum buffers is more adequate, and these are very fast.
