I and David use a multifunction card from cnc4pc to function a few ways. One, to control the router, to have inputs for estop and limits, three to create a safety charge pump in case your computer crashes and it will signal an estop, and four to act as a barrier between your pc and the xylotex driver. More or less, instead of frying your mother board or electronics on your computer, it will fry some components on the board which are much cheaper to replace. I choose to get the 4 boards sep. but arturo has the new one in stock again now. If it was me I would go with the multifunction card, it has everything included and soldered together and minimizes wiring and connecting. |
