I attached the robot file. This is still a draft as the 3D model does not match the kinematic parameters. I'm sorry we took so long to add this robot. It is not easy for us to work with the 3D models you provided. To make sure we have the correct dimensions of the robot it would be best if you can provide us with the original STEP file provided by Fanuc.
I believe the kinematic parameters are correct but it may be better to double check with the following parameters:
DH_THETA
DH_D
DH_A
DH_ALPHA
You can find these in the system parameters $MRR_GRP[1]
