I think you miss-count us, Andrew. There are, I would estimate well over
1000 world wide users of LinuxCNC, but most are more mechanics than code
carvers. They rarely show up on a mailing list, bugging the vendor that
sold them the package, having bought a software package for a sizeable
yearly seat fee because it makes them money in their shops. But while
they may make heavy use of those code generators, they are feeding that
output into linuxcnc about 25% of the time. There are of course
commercial machine control packages, but they can run into the 5th
digit, and most are frozen in the 1970's for features we've been doing
better for many years. They are stuck at 4 axises, we've been doing 9
for decades. At one time it was ITAR software, because it could carve a
submarine screw that didn't cavitate but Hitachi-America shipped it on a
machine that found its way to china, and now the whole world knows how
to machine quiet screws for their submarines. Horse out of the barn,
hitachi got a wrist slap, and we were taken off the ITAR list.

But that also limits what the machine can otherwise do. I have cat6 to
every machine and every machine can look up what I need to know on the
net. I wouldn't have it any other way, but then I am also a hobbyist in
my dotage. Retired from a tv Chief Engineer's chair I warmed for 18
years, and workbench as a CET, but still keeping the local radio station
on the air.

Than you Andy C, and have a virtual near beer with me tomorrow as I
celebrate the 86th. Diabetics aren't supposed to drink the real stuff.
