Thank you all. What you mentioned is what I have currently done, simply running the zero and making the adjustments, but as you know, that just gets me "close"
Have not kept track and looked for patterns though, will try that.
Just a bit difficult as and joint is liable to be off, depending on motion during crash.
....Just confused on why it should even need re mastering at all when no power is lost, no gears actually slip, etc.
Looks like I need to start keeping some more notes and try to track down the source over the next several months.
And the program adjust function sounds like what I was after, may try that in the meantime, as well as just for the experience with different features.
Thanks!
