Why does my axis jumps during a FindIndex function after the index is found? My offset is set to 0.

I'm executing the FindIndex function and the axis searches in the proper direction to the index pulse. When the index is found, the axis jumps at a faster velocity as if an offset was entered.

Make sure you do not accidentally have the axes set up as open loop. Let me know how this works.

We found 2 problems that were causing the flexFindIndex call to fail. The first was that the encoder counts were incorrect and the other was that the encoder A and B channels needed to be reversed due to the orientation of our motor/encoder with respect to the leadscrew. I've attached a picture of the orientation of the motor/encoder and leadscrew assembly.
