Homemade semi-automatic pellet gun help.

[Makeshift_Marksman]

Hey guys currently I have a smei auto airgun operating on 200psi with a 3way 2 position valve, qev and dump chamber with a electric solenoid to chamber rounds. currently im using an esp32 to time the valve on and off for 10-20 milliseconds. For some reason i can get the valve to turn on and off quicker for less that 10 milli seconds. The 3 way 2 pos solenoid valve runs off a mosfet to switch on and off but wont click open when i set the milliseconds for less than 10. Any advice would be appreciated. Also any advice on how to post videos here would be appreciated.

So does it fire from an "open bolt" or closed? Like are the solenoid and solenoid valve energized simultaneously?
I would hazard a guess it has to do with your power supply and isolation between the solenoids but a little more detail could help.
Also that sounds awesome, hope you share soon!
