Base offset oddity

I’m trying to figure out why there’s a strange offset relative to the base of the robot (CB3). From my expertly drawn picture, the center of our table reads 0 in the Y plane, but is not aligned with the center of the base. It’s a good 1/4" off. I could theoretically move the base over the 1/4", and the center of the table would be aligned with the center of the robot, but it’ll show as -0.25" in polyscope. Are there settings anywhere to adjust this? Does it need to be re-calibrated? We weren’t the ones that set up this robot, so we’re not entirely sure how the vendor did it.

Here are a couple of possibilities.

  1. The Tool Center Point is offset
  2. Is the feature set to base when you are looking at the dimensions?
