Hi David, I can see that, after thinking about it a little. But I do get smoother motion then if I command just one move. I do like the idea of altering the ...

The problem there is that Bioloid servos are not low cost, ie £6 or so say $10. Maybe if I get some really good jobs I might treat myself but until then or...
