I worked with a version about 5 years earlier than your first, and while there WERE a few quirks, there wasn't anything I'd call a serious bug. (Now, I did skip some versions, and usually wait for things to get stable before adopting it.

It was pretty unreliable, and had 3 major breakdowns in about 6 months. I made up some cables so I could plug back and fort between the A-B and EMC. I tried EMC, finally got it working after a legendary saga of install problems, and found several serious problems. I can't remember what they were now, but they made it pretty unusable for machining. I sent a request to Fred Proctor at NIST, and he sent me a revision in a couple of days. I cabled back to EMC, and the A-B was never turned back on again! The A-B control DID have some nice machine operator-friendly features, but the performance and reliability of EMC made me very happy, even though it occasionally hung up the screen GUI. That problem was fixed in early 1999, and it has been an excellent "tool", ie. you just turn it on, and it does exactly what you want, and expect, every time. If it DOESN'T, it is because I did something wrong, EMC was working exactly to its specs. Now, one comment I should make is I do not use steppers, and have not used the software step generation code in any of my machines or with the EMC-related hardware I sell. There HAVE been some issues with that, including one that has apparently just been resolved. Also, I don't use backlash compensation, as my Bridgeport has very tight ballscrews, and I think that this is generally a bad thing to do, except on a drilling machine, maybe. >You can email me directly if you care to expand on what "FUD" means. > > > Fear, Uncertainty, Doubt -- something naysayers spread to disparage something they don't want to succeed.
