They happen to be completely compatible and shouldn't cause problems, but it's usually a good idea to keep the program as "happy" as possible.
Most pneumatic systems will "work" down to 30 psi without difficulty, though they of course won't provide much force. I don't think your symptoms can be explained by anything in the code. It's probably time to examine your pneumatic system in detail. What kind of solenoid valves are you using? Do they have a manual actuation feature, perhaps a small button or lever?
Or maybe whatever you have the cylinder connected to just requires that much force in order to move. What is the mechanism you're trying to activate with the cylinder?

We solved our problems with solenoids. Thanks for your help. I guess I was lack of some essential information about solenoid. First we changed the code and then checked our wiring. We found out that our solenoid breakout is not fed by 24v on pdb and fixed it by wiring it to C and NC outs. All of our solenoids are 24v, we missed that detail. We can finally drive our robot, shift and control other pneumatic systems properly.
Now, the only thing that was left is vision processing in autonomous. We looked over the example code and tried to understand it. We could customize our dashboard by the example code. However, we still don't have any idea how to link the example code to our robot actions in autonomous mode. I know this thread is going far from its title and hope that it's not a problem. Do you have any simple and clear resources about using vision processing code in auto mode?
