    Question Tuning Servos with out an O-scope?

    I just received my gecko 320's and the directions indicate how to tune servos using an O-scope. As I don't own an O-scope what would be the best way to tune the servos without one?
    Thanks!

    Bob,
    Good question. I got my 320's a few days ago and have not had time to hook them up yet but was wondering the same thing. Hope someone will enlighten us. Ron

    There is a poor mans method, and basically you run a load of G00 moves back and forth on one axis.
    G00 x0
    G00 x5
    G00 x0
    G00 x5
    and keep on looping. As you adjust the accelleration values, the servos will start to stall. Now adjust your geckos, to stop the stalling. Not too much gain that the servos "sing" while stationary, but too little or you will have a "spongey" response. Adjust accelleration again if you need to, and double check settings on gecko. You can check again by using a smaller step eg, G00 x1, G00 x0 on a loop, or perhaps a larger step.
    Hopefully there is a more technical method, but that's how I do it!
