| Trackball problem, ending spin...Help plz. |

I am glad you posted this. I have had the same problem with a 3" happs trackball. It drove me crazy, so I ordered new bearings and rollers that only helped slightly. I would really like someone to figure out a fix for this if possible. Maybe I'm wrong, but I was under the impression that most trackballs (with 3 rollers) will do this because they are taking the path of least resistance. In other words, they will want to roll in the direction of the diagonal roller at the bottom of the trackball. However, I have an angled CP (1 inch angle over 22 inches deep). It might be less evident in a flat CP, where the weight of the ball is more evenly distributed. I would be surprised if anyones trackball does not veer to the left a little bit at the top of their desktop if they give the trackball a good spin upwards. I checked for this problem on arcade Golden Tee machines, and so far all four I have checked display the same problem (but not affecting gameplay). I wouldn't worry about it too much unless gameplay is affected. In my case it is not. By the time the leftward movement occurs, the game has already registered the correct direction. |

Isn't the backspin one of the signs of a slow trackball interface? I had a mini-pac and tried 3 different trackballs, a 2.5 inch ultimarc and 2 betson 3" trackballs, and all had a problem of spinning backwards at the end of the shot when playing bowling/golf games. I replaced the mini-pac with one of GGG's trackball modules, and all the trackballs now work perfectly. |

I've never personally observed it, but I don't really play trackball games. And when I DO play trackball games, they're ones where I keep my fingers on the ball all the time (like Missile Command) --- Quote from: sWampy on April 24, 2006, 03:17:27 pm ---Isn't the backspin one of the signs of a slow trackball interface? --- End quote --- Yeah, but this isn't a 'backspin' problem, per se. Backspin (usually) refers to what happens when you spin the ball too fast for the encoder to keep up (or something to that extent). What's being described here is a physical 'drift' or 'off axis spin' that is physically happening to the ball. It's not something that's being observed in game play, it's being observed in real life. That is, if I'm understanding correctly. I haven't personally observed this phenomenon. |

I have a friend who had the same problem with a golden tee. Turns out it's not really a problem. the algorithm for the golf stroke (or bowling ball roll, or whatever) knows that trackballs do that and it has no bearing on the game. Even if you swing up and right, the last motion the ball makes before it stops is up and left. If you want to see some messed up trackball action, put it in upside down, and then reverse the encoders. In a game like missile command, everyhting will work perfectly normal, but in GT everything you hit will go directly right, as it's expecting the ball to tail off the other way. Kinda neat. |

Hmm, well that makes me feel a little better, I still may lube the bearings, like really soon, I'll probably post tonight if I do so today. Edit: Thanks |
