And since its running, let me get the loadrt stuff to see if thats correct.
That is: loadrt hm2_pci config="num_encoders=1 num_pwmgens=1 num_stepgens=4" Anything else I need to add to that? As far as I know the 7i76 is still factory programmed as I have not specified a firmware for it, and have no clue how to do it if its needed, all I done is put the 5i25_7i76_7i78.bit file into the 5i25. Now, because the pdm is being fed to 5i25-p2 now, I'll still have to use the rather rube goldberg kit to make a 12 volt enable for Jons pwm-servo amp. But its worked well for a couple years in spite of itself. I am currently using charge buckets to control a couple 40 amp SSR's that soft start the spindle supply so those hacks will still be needed. Without the delays of the charge buckets, there are instances at powerup that will trip a 20 amp service breaker nearly 100% of the time. Too many microfarads in that supply, so it gets started with a 50 ohm 100 watt R to control the inrush. Thanks Peter. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
