From my understanding of DUOCore, unless the program is basically expecting DUAL Processors (or is made to switch from task to task FAST in Windows), it really don't matter for now. Best bet is run tests without dropping lower than to potentially break a cutter because of Windows hiccups....as of about a week ago, I have problems with getting the diagnostic screen even showing the interrupt times and all, and I'm NOT USING a CNC controller or machine as yet either...
My advise is this, do not ask just 1 single person on anything, TEST the opinions/answers, and if have doubts on that, then be all the more specific...I'm not running a machine as yet myself, but believe me, I'm going to be using foam or scrap junk to test and check here first, THEN if things get screwed-up, then all the loss I'm looking at is the time to make a block of foam AND my time to watch what happens (IE, even using wood, if not careful, a cutter CAN potentially be damaged...and/or yourself).

New, yes. At posting time? (TO BE VERIFIED and iff allowed to stand as is OR not, fair enough.
