Hello
Im working with a KUKA KR 10 R900 sixx and im having some problems with the air pressure. the pressure supplied is about 6 bar but im getting closer to 1.5 bar on all three solenoid outputs. I have two pneumatic grippers, one is rated for 2 bar and the other for 6. Ive written a test program and tried both of them and the first opens, but the other one doesnt, so im guessing it isnt a software issue. the robot has also been sitting in a back room for probably 3 years with minimal use so maybe some components aged. I cant hear any hissing directly from the robot, but the supply pipe also has a small leak so that might cover up any slight hissing the robot makes.
I would really appreciate any pointers to what the problem could be
