Hello

I just subscribed to this group and have browsed some of the postings.
Great stuff! I had just dusted off my home made cnc about 3 weeks ago,
and put a new stepper controller on, so I am ready for some fun. I also
have been collecting spare machine tool parts, and have more than enough
to build a new machine. Hence this group is right up my alley.

I am fascinated by the 'NIST' group I have been reading about here. I
want to ask a question to those familiar with this. Is the NIST group
privately funded? Or is it like the GNU consortium? I am very
impressed with the NIST software. So you are really able to close 3
servo loops in real time with 100 micro second sample times over a
parallel port in Linux? That is amazing-- especially given your are
doing feed forward velocity and jerk control in addition to PID. I
think I will bring some spare brushess motors and drivers home from work
for a weekend and try this thing out. I want to learn more.
