unless you-re ok with two positions - fully retracted/extended stroke - it's quite difficult to control stroke length of a pneumatic actuator.
So are you saying that it means extra code? That it will cost more? Or can't be done?The actuators need to be able to be in any position between fully retracted and fully extended. I don't have enough knowledge about how to do it, other than to suggest that I have seen this concept successfully work with servo valves and servo amplifiers.
