I didn't see an "addf" listed in this message, but to link it into the rest of the code, you will need that too. This addf is the only statement that is processed in the order of its position in the addf order for the servo-thread, so the addf for lincurve.0 will need to be after the addf for motion. It sound's like you are getting close. Gene, That was a whoopsie. I posted an old hal file, one of my first iterations that I hadn't synced to the operational one. My follow up email posted the correct one. Ya, I thinkit's getting pretty close. It's blatantly obvious my hal coding skills need a little work. ;-) Mark -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
