I had a lengthy conversation with Patrick at Stern yesterday. He phoned me back in response to an email I sent outlining my problems, and he did it after hours which I thought was very cool of him. Here are a few things I learned from speaking with him...
Air balls: I get a lot of them. He pointed out to me that the vast majority of air balls are due to Sparky's feet, or the overpowered right sling. The feet there is no way to address, the OP right sling will be fixed in software update 1.15.
Ball trough eject: Most of the time it would eject into the shooter lane wall and then go straight back down the eject scoop. Then spit out two balls, or no balls, or cause me to scream profanities at nobody. Simple fix by bending the eject scoop tab TOWARDS the plunger. The ball now ejects perfectly every single time.
Inline drop target gong show: They are well aware of all of the issues and are putting a kit together. The assembly designers are currently working on a fix for the stubborn drops rejecting balls, and we'll need to be patient until they have a solution. The opto reset issue has already been addressed and they have a retrofit available for the opto board. Contact them.
Software v1.15: Lyman is working on it and it should have some significant improvements. Patrick didn't ask me to keep the info under wraps or anything but I'm not sure if they want the release date for v1.15 announced. I WILL say that you will be playing a whole new Metallica game next weekend.
Cheers,
Greg
