Pneumatics not working
 

We are having a problem with our pneumatics. When we enable the robot the compressor automatically turns on and drive the piston out, we can't get it back in with out releasing the valve or disabling the robot.

The valves will remain in whatever position they were in when you last used them. If that position is sending air to the cylinder port that extends the rod then that's what it will do when the compressor charges the system.

To get them to retract just push in the little button on top of the valve (by the connectors) that will cause the valve to change over to the other position. If you push one and nothing happens simply push the other one on the other end.

BTW there needs to be a little air in the system for this to work.
