Posting the manuals that KUKA gives away with the robots is allowed. Posting the training manuals from KUKA College training courses is not allowed.
The information on wiring X11 is not considered proprietary, and as such presents no problems being posted.
Many of the KUKA manuals are available in the "Manuals, Software, and Tools" sub-forum of this forum.
Thanks for the clarification.
Here's the KRC5 manual.
