Hi there.. I'm looking for yet another control board after the original hyteckworks board supplied with my kit had a short between the USB connector and the board, and fried itself, though i wasn't overly happy with its 3v logic system anyway. I've recently purchased a "digital dream cnc ddumv1.05" which boasted 400khz processing, but ultimately got thrown in the bin after just 3 days of trying to get the thing to work.. loosing USB connection, spazing out randomly and the thing didn't understand arc moves!!! I should have done some research on it before purchasing, if i had i would have found out the manufacturer has shut up shop and not offering any support, and many others finding the same issues. Though you can still buy these on amazon!!! So having learnt my lesson.. thought id better get some advise on the matter. I need a mach3 compatible 5 axis USB or Ethernet board that is going to be reliable.. smooth, has good support, and runs on 5v logic. your suggestions here will be most appreciated. Thanks Jon.
