Hey Jay, I measured the distance from faceplate to the ATI pin that was taught and it's 129mm.
Nation, I think you cracked the case. That is exactly what I was looking for, some actual variable that I could compare against the old back up program from July.
On the left side of the image is the old backup from july which seems to have the flange setup as per your description. On the right side, is the current setup of the robot with normal flange selected. This at least gives me actual numbers to confirm that there was a change in the robot at some point and that is what i was looking for.
Thank you all for your help, much appreciated!
