I think, if I interpret Carel's post properly, that he and I are on the same page in this regard: newer faster PC's aren't providing better or faster code processing with regard to today's CNC controls. Complexity in search of a need.
I'm amazed that Bridgeport did 4 axis machining with their VMC 1000's back in late 90's and only used a DOS box and BMDC3 for control. Some were 386 and some 486 but no Pentiums. In fact, you can't even use a Pentium faster than 133 to retrofit to the "legacy" systems.
What did they know about machine control that they incorporated into their DOS based DX32 system that isn't being or can't be done today???
Hmmm. Simultaneous motion with legacy, nearly free O/S's and PC's. Talk about value and a DIY dream. In some regards, the guys who did DOS programming had to be smarter.
Oh if there were only a legacy based DIY servo style retrofit kit that worked. Probably wouldn't sell - too much reliance on windoze anymore. |
