    Finally the Arduino fits well in the updated FingerStarter_Kit.
    (see picture)
    The new pulley and adapter for the small servo also fits well.

    I need to say…..
    I’ve found a other servo, which is a bit bigger and has 10gr more weight
    The good thing is, a standard pulley like Futaba will fit.
    And it has 2,1kg more torque as the small one.

    I hope to get them soon…

    This makes it more easy to use the pulley’s which I’ve made earlier.

    • Very cool Marten! Once the finger is assembled, a little video will be nice to see!

      • Hi Gaël,

        Thanks and yes, when all is running fine together…. I will share a “little” video 🙂
        I think this will happen, when I get the new servo’s because of the fit to the pulley’s.
        I hope to get them next Tuesday.

    • when trying to reduce the forarms weight – did you experiment with getting less weight from the printed parts too? Just had a chance to look at a fiber enforced part at an exhibition. It had a thin layer of fiber on top and bottom of the part (needs 2 extruders) but showed impressing strenght.

      • Hi Juerg,

        I hope to save some weights with the new servo’s.
        They have three times less weight then the servo’s which I’m using now.
        And the servobed will be smaller.

        About the printing parts.
        I’ve done one finger with Carbon fill and is very lite.
        I’m only not sure enough, if this is strong enough !

        • how did you print the carbon item? Layer size? Perimeters? Fill?
          what tensions are you using? did you try to reduce friction of the tensions?
