I will consider, and try to get a list to you tomorrow. Basically only 4 stepgens, on the default pins and disconnect the pwm "dir" on pin 16 so I can handle it in my hal file. Can that be done? I can handle everything else I believe. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
