...and to add different cushioning thats more gripy
I use rubber bands cut out of a bike inner tube, dipped in acetone to remove any greasy residues.
I've also been drawing up to 2.5 amps during the uses, does what does yours draw?
I tested my servo's last year and had no values over 1500mA YMMV
and to add different cushioning thats more gripy as one of my gripers is able to grip the cube while the other obviously can't.
Strange ::) this call for additional investigation Did you try inverting Right/Left servo connectors ?? did it transfer problem to the right servo ??
