pbnation said:On your trigger there is an HES magnet screw that makes the connection between the trigger, solenoid, and eye sensor board. This set screw is VERY sensative and needs to be lined up just right. First, make sure its still there, they do tend to snap off it the screw it adjusted improperly. It will look like this when you remove the frame.

Move that set screw to its maximum and minimum positions, be careful not to thread it out so far that the magnet snaps off the top. Also make sure you put your finger or a squeegee down the breach to trip the eyes so you will hear the noise when the magnet is properly aligned. Make very small adjustments and shoot after each change to see if it works.
If this doesnt work make sure you have the magnet that is attached to the upper body of your marker.
