OK cheers TygerDawg
Much of the oil has spilled out on the floor due to a faulty joint 6 o-ring lol. I may have to bite the bullet and buy some of the oil listed in the manual.
I guess playing about with a long obsolete bot means I can dig around much deeper without a boss yelling at me. Its interesting though, as I dont think the staubli wrist design has changed so much in the last 15 years. Its impossible to find drawings or schametics of it, so perhaps they are still very protective of it. The curiosity is maddening lol.
They are 100% obsolete sadly, I have just been lucky enough to get my hands on one and am self-teaching robotics We are building an open source controller and have it running from linuxcnc, capable of doing gcode programs from Fusion360. Is a lot of fun for sure, but everything is like solving a mystery!
Anyway cheers for your thoughts, if anything else pops into your head please do let me know, even little tidbits of info can be amazingly helpful : )
