Thanks Andy, I'll take a look at that. (calls up very simple man page) Yes, that does look as if it could be useful. Can the scale parameter be used as a pin? With the intention of giving it a larger 'near'=true output at the higher speeds? One of the problems I've seen occasionally with the previous setup I ran most of last summer, was that the trip was bidirectional, and if the spindle was turning at a good rate when the stop button was hit, the error developed because of the perceived spindle over-speed, usually tripped the the thing too, a minor pita. I never got around to putting in an error had to be positive only logic block. Sort of a duh at the time, but I was making 209 nipples for one of my BP rifles and having fun at the time. :) Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
