Sometimes, it doesn't even shoot, then you can sweet spot it into random count bursts, like 3 shot-6shot-4shot-7shot. Then some times my board fullautoes.
It makes no sense, given that I have a Nerve board with the rebound off.
adjust the post travel, you might have it so that when fully back it barely actuates the switch, and the little bounce is enough to make it shoot again. Or maybe you have a bad boadm, send smart parts an email.
