Hey fellow owners. I have only had my CSI for about a month now but sometimes when the ball hits this fish paper it activates the centerfuge enter opto. Have you had this issue before?

I unscrewed and removed the centrifuge plastic which the optos are connected to and squeezed the optos together a little bit in switch test and they do not appear to have bad solder as I am able to flex them a decent little bit before they register.

I believe that it is possible that the optos are not very well centered in the metal entrance guide in the little holes. So just a little bit of flex will break the opto-beam when the fish paper is hit. That is a possible theory anyways.

Any solutions out there that anyone has tried and has worked?

Thanks for the reply. My optos for the centrifuge register fine in switch test (I also removed the top centrifuge plastic and tested them). It only falsely registers with a direct hit from the ball to that outside fish paper which pushes on the opto board and causes it to trigger as it is breaking the beam with the board bending inward a bit. That is what makes me think it is not an actually an opto issue. Kind of a bad design issue with that fish paper and opto being so close to the skull ramp entrance that it is accessible to a ball hit.
