Re: Piston throw control

Our team is trying to do something similar with an arm and it must be fairly acute b/c we are trying to use the pneumatics to position the multiplier ball.
I have looked through the other thread and I was wondering if anyone has some great up close pictures that make a multi-position arm without a lot of programming.

Re: Piston throw control

The minimal amount of programming is a on/off switch for the single solenoid and a extended/retracted switch for the double solenoid. You can do this manually for practice. Choose the direction you want extend/retract and then turn on the single to move and turn off to stop where you want. Slow movements down by using the needle valves on the cyclinder and closing them all the way and then slightly opening them.

Re: Piston throw control

If you want it to stop in the same place all the time just take a piece of pipe and cut it to the right length and then slide it onto the shaft

Re: Piston throw control

Or I could just buy the SMC "off the shelf" three stage solenoid...

Re: Piston throw control

Actually, if you follow the flow chart, you cannot use any off the shelf solenoids.

Electronics (yes) -> Is the part a motor, solenoid, pump, or other actuator? (yes) -> No, it may not be used.
