I have been running EMC since 1998. I have never had it cause a "wrong move" that was due to computer failure, software corruption, or software error. I have had it do a number of "wrong moves" due to OPERATOR error, one time bringing a boring head down on my hand. I thought about the likelihood of a computer malfunction vs. operator error for a moment, and then carefully pushed the RIGHT button and took the tool off my hand. I thought about hitting E-stop and winding it up manually, and decided it was me that made the mistake. So, that is about 9 years of use with NOTHING I could ever lay to abnormal operation of the software. I have also had to abort or Estop a whole bunch of CNC programs that had mistakes in them, or I forgot to set the axes correctly, or an endless number of goofs. Forgetting to set the axes at all, or making a mistake while using the edge finder and setting to +0.1" instead of -0.1" is very common, I have done this literally hundreds of times!
On the other hand, my A-B 7320 CNC control croaked on me 3 times in the 9 months or so I used it before EMC was ready for real work, back in 1997-1998. This never wrecked any work, but it sure could have if I'd been cutting when it went down. (I have had an occasional hardware problem on my CNC system with EMC, usually due to bad connections somewhere, but it will show up when I try to start the system up, so I don't have tooling and workpieces loaded yet.)
