In other places it seems like the "needle valves" are on top of the push cylinder air supply. We dissembled on of the push cylinder air fittings and there was no needle value underneath.
Are needle valves a real thing? If so where are they located?
The manual implies that you could add some resistance to the push feeder slowing down the action (and shockwave) from the push. Did the needle valves exist on some models?
All of our push feeders have needle valves in open and close line. The best way to reduce the push feeder force is to reduce the air pressure by adjusting the pressure regulator.
The problem with adjusting the regulator - which we have done, is that different parts require different force on feeder. We are considering grouping the parts on plastic tape to use lower air pressure on - so we can run the board with paper tape parts, then turn the pressure down. My employee succeeded in getting some SOT23 transistors to place yesterday but I don't know what the strategy was.
Regarding needle valves - where are they? And how do I adjust them? The illustration is the manual was hard to understand.
The needle valves are fitted to the push cylinder. But there is no need to add different force to different tapes. Your problem depends on other wrong settings. Please take a video and send to me plus your zipped *.fig and config.ini.
As I see it - adding resistance into an air line is about the same thing as an RC low pass filter. Needle valve = resistance Air cylinder = capacitance
