servo hacking

sometimes when i hack my servos for 360degree rotation even if i dont touch the electronics and motor on the bottom the servo gets a mind of its own (it wont reverse and i cant change the speed of the servo or the direction its moving

)

What servos do you got?

Either that or you've knackered the pot. Don't use superglue!

I used superglue on mine, and they were OK. THey do creep slightly, but that's cos I used thme before the glue was set (stupidly)

You disconnect the mechanical drive to the pot but there is still the chance it could move and there by change your zero position. It is nomal to put a small amount of glue on the pot to stop it from moving. Make sure the glue get no where near where the wiper touches the track as this can cause problems especially with superglue that has the ability to seep into such places.

glue guns are pretty good. Make one hell of a mess sometimes though
