Re: Mulit-postioning with pnuematics this year?

to fix the possible leaks, we (jdiwnab and I) retubed the whole system and replaced the old valves with Festos from last year. I also modified the design so that each Festo controlled one side of the cylinder, basically A goes to the cylinder, B is a blocked loop, P is pressure, EA is blocked, and EB is open to atmosphere. This is true for both valves. Why would the piston get stuck at midway and not move up or down from there? Have I inadvertently made it so that the air cannot exhaust itself from either side?

Thanx

Squirrel
