error is only proportional to the load when your pid has no i term. an i term will reduce the error to zero, at any load. To get the load you have to compare the output to the feedback. >> >> On Mon, Oct 17, 2016 at 11:03 AM, Stuart Stevenson <stus...@gmail.com> > wrote: >>> You can find explanations in the documentation >>> >>> >>> HOME_OFFSET = 0.0 - the amount you >>> want to table to move from the homed zero position after the index >>> pulse is found and the encoder position has been set to zero.
