Iterative Alignment Error

Hey, friends. Hoping someone can help me. I keep getting an 'Iterative Alignment Error' on my programs and I'm not sure why... I've attached my code and a picture of the CAD I'm working with.

I'm aligning on 3 sample hits on top of 3 bushings pointing in the x
I'm rotating in two bushings into the Z
I'm using one bushing for the origin.

I don't know why it isn't working Disappointed

Save meeeeeeeeeee

  • He's leveling as well as rotating to the same features. Would that mess things up? In a less complex alignment...If I leveled to a plane in the Z+, I couldn't then rotate to that plane as well or an alignment error would be triggered.
  • No, with tooling balls or tooling holes, this is the standard procedure.

    Imagine having 3 pool balls glued to a table. Instead of a triangle to rack, we will use a square rack, but put a top on the rack. Put the rack down on the 3 balls, this levels the rack onto the 3 balls. Then pull one wall of the rack against 2 balls, this rotates to the 2 balls, but doesn't interfere with the level. Then pull an adjacent wall up against one of the 2 rotating balls, this stops the final translation and doesn't affect the level or rotate.
