Final part dimensions out of tolerance

[MikeH (Michael Hentges)]

I would look at this post: Testing and tuning OF for accuracy - #15 by cyberreefguru - but instead of using “eyeballs” on a ruler to see if the movement is correct, machine a pocket the largest size your accurate caliper can measure, and make adjustments from there. You should be able to adjust the distance/step setting to get this dialed in a little closer.
