also when I disconnect the usb cable, a red light flashes 3 times when I press the button. do you think I should have 2 power supplies, 1 for the servo channels and one for the processor?
You should be able to use one power supply for the whole system. I suspect that when you are pushing the button to control your servos, your batteries’ voltage drops, which causes a “brownout reset”. The Maestro indicates that there was a brownout reset by blinking the red LED briefly. More information about this can be found in the “Indicator LEDs” section of the Maestro’s user’s guide.
What kind of AA batteries are you using? Are they freshly charged? How did you connect the batteries? A picture of your setup showing all the connections would be helpful. Also, please save a settings file using the Maestro Control Center and post it here so we can see your settings.

I have 4 AA batteries connected to the servo channels, but I want to be able to power the whole thing without having to use usb. any ideas?
Hello.
The “Powering the Maestro” section of the Maestro’s user’s guide has a good explanation of how to wire the Maestro for one power supply.

ok I have sorted all that, thanks for all your help.
is there a way to put a code in that will shut off the servo’s if 1 of them is out of time slightly with the other…
eg: both servos move from 2000 - 6000, but servo A reaches its maximum at 5900. so servo B keeps trying to move to its final point.
can I put a code in to shut off servo B after a slight delay of it trying to move. (realising it cant finish so shuts off)
iv tried fine tuning each servo (servo A 5993, servo B 5897) for example. but cant seem to get it right. they are prob mounted in slightly different places and not square to each other, so could do with this kind of ‘cut off’ code
To make the servos respond based on their position, you would need some sort of feedback system. This can not be accomplished with just standard hobby RC servos and a Maestro.

thanks guys. really helped me out a lot. just need to get my led’s to blink few times after a short delay.
so… press button… slight delay… blinking leds’s, then stay on until button is pressed again.
iv looked at a couple of examples that I could find but no good. HELP ME PLEASE !
