Dear group, I am trying to understand the Z of my up camera. I want the working height to be -22.5mm, which is the height of my PCB. I set this height for the up camera position and then ran the advanced calibration. At the end, the camera height had been set to a different value (-23.66). I don't understand why it changed. When I go to the "position" tab of the up camera and place the nozzle at the camera location, the nozzle goes to -21.66, +2mm higher than the camera Z. I don't understand this 2mm offset either.
Thanks for any insight!
Jim
