Hi all; Years ago ISTR there was a setting in the intro to the .ini file that set the scale of the effect of the spindle speed +- buttons.
In trying to see if I can incorporate a limit3 whose maxa sets the accel limit applied to the pid.s.commnd, I have tried to get to a unity gain thru the chain for a starting point. I have a limit2 set to allow only between -0.97 and 0.97 as inputs to the hm2_5i25_pwmgen.0.value. But the increments coming out of motion.spindle-speed-out-rps aren't anywhere being fractional at that point. A click on either dir button gets me either -0.01666667 or 0.01666667, which is approximately what I have set to overcome friction by use of the pid.s.bias input. That .03 addition turns it into -0.4666667 or 0.0466667 which will make the spindle turn about 10 rpm. But a click on the + button multiplies that by 100! to 1.666667 TBE, off scale, and tripping Jons pwm-servo driver off before the motor even clicks. Do I have to put a scale module with a gain ofless than 0.01 after the pid.s.output to combat this, or is there another approved method to scale that back to a sensible, usable value? Maybe pid.s.FF0 = 0.005? That I have not tried yet. But will. Thanks all. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
