I think you ought to be able to adjust the bldc component to offset the commutation. (bldc.encoder-offset) However that is no help if the hall transitions are just inconsistent. Have you tried qhi? That should avoid any inconsistency due to Hall transitions, at the (minor) expense of running trapezoidally for up to a full rev. In your situation, with a machine to get finished, I might be tempted to run trapezoidal permanently anyway. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
