Okay People. If you want the latest, up-to-date, information on the Openbuilds Apex Controller, then you need to go to .......... FORUMS - Scroll down to the, ELECTRONICS Section, (which is almost the Bottom left hand corner, just before you fall off the page ), and then, CONTROLLER BOARDS - and finally, BLACK BOX MOTION CONTROL SYSTEM. Where you will find Mark's Latest information. What are you still doing HERE? Get on down there and have a Great Read. It's worth the trip.
