Hopefully it's final :)

Thanks Stephen and Manfredi for the help.
For those with similar setups this might be helpful:

Ack!
Unless you're running a servo machine at 1000m/min (yes, 1 kilometer per
minute), you don't need a 60 microsecond servo rate. For most "normal"
machines -
Thanks for the help.
I set my base period to 15,000, servo period to 60,000 and traj
period to 600,000.
I lowered my max vel to .75 (45 inches per minute, plenty fast
enough). Everything seems happy except the realtime error which I
have not run to ground yet.

I am using EMC2 and a gecko servo drive to drive a servo I have
mounted on my Millrite.
When I set the max speed to 1.0 (I think that is 1 ips or 60 ipm) I
get an error saying that the velocity is too high.
I the motor/encoder/gecko drive require 2000 steps per rev and the
lead screw is 5 tpi an
