BOE problems

chsom

I am using a BOE trying·to make a monster with a tongue that goes out, picks up an item and comes back.·I am·using the following coding. The problem is that it goes out just fine. Coming back the servos that are sliding the tongue back start jumping rather than coming back smoothly. Thus the back motion takes a long period of time.

Can anyone look at the coding and tell me if there is a mistake in it?

Thanks

If your debug statements run smoothly then I would say your problem is mechanical. Too heavy a load maybe?

Okay, so I tried using three other servos that are not connected to anything, thus they have no load and they still do the same thing coming back.

Thanks...
