I do not get, how does this work. With the some PID settings, I jog Z axis motor back and forth and in HalScope I see that max value for pid.2.output has been 0.27 or so. How comes that with _smaller_ acceleration and velocity values and with the same PID settings I can get saturated pid output? -- Viesturs If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
