One possibility is that the encoder scale (in bldc) has the wrong sign. (Or maybe that the pole counts is wrong) Alternatively it might be that there is some coupling between the power phases and the encoder signals on the motor. I hope it isn't that, it would be much harder to sort out. > approximately 4000 pulses in each > direction, it increments or decrements rawcounts pin correctly as the > motor is turned in different directions.

These should all be "exactly" but I assume you are talking about the inexactitude of manual movements. -- 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.
