Yeah, it's me again. Before any of you new comers to the Linux community start ragging how Linux isn't ready for prime time, go to these sites. www.sherline.com [look into their CNC systems] www.linuxcnc.org or googled "Enhanced Machine Control" or "rtlinux". These are examples of the linux operating systems used in mission critical 'real time' mode. The original writers of the Enhanced Machine Control, or emc, software was NIST (National Institute of Standards and Technology), a U.S. government entity. The software, from the beginning, was written for linux. There are many links from the sites that I mentioned, follow them and learn. Linux is different things to different people. -Wayde ...linux user and long time machinist...
