The reason that nobody talks here is that there is an email list for EMC. Also, a lot of discussion on the CCED yahoo email list. If you are serious about using EMC, look at
www.linuxcnc.org
There is also an IRC channel.
Both TurboCNC and Mach2 started with EMC. Sherline is selling mills with EMC installed. There are lots of users of EMC around the world. If you are using true servos and not stepper emulation, EMC is the only way to go that doesn't cost big bucks.
