I also hauled the drivers box down to the garage and found out why the ABC motor was running hot. It had the 50% throttle when idle switch set ok, but the switch next was miss-placed so it was getting 4.2 amps when moving, but it never lost a step so I doubt the armature was hurt. and 2.1 when idle. Set them all to 2.84 amps & left it running idled for about an hour with heating of about 7 or 8 degrees, since that is only 1.42 amps when idling. Sweet. But that new D525 computer will be next Monday getting here, so I'm still figiting about. I don't mind wasting time, I am decently good at it, but I hate enforced idleness. I also booted the old box and found its latency sucked, just moving the std sized glxgears window around on the screen took the jitter from 16 u-secs to around 120 u-secs. Where can I find some real docs on this isolcpu thingy? Thanks all. Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
