Hello everyone, at work our maintenance department replaced the joint 1 motor on our Fanuc welding robot. Unfortunately they did not mark the robot first for home. The robot is in a Lincoln e Cell weld cell. Does anyone know where I should be looking for the factory witness marks on this 100iBe robot? It is really hard to see them because of the (limit switch plate) plate under axis 1. Also it is really dirty. I've been scrubbing the arm and I found witness marks on other axis so I know at least some axis has them.
As you can see from the controller picture the position of J1 is in in the picture corresponds to J1 actual position on the read out. Maybe I'm somewhere close to witness mark zero?
Here are some pictures for reference.
