Mini Maestro Does not work properly without USB

Support Servo controllers and servos

Dear Forum Members,

I’ve been having a problem with the Mini Maestro 12. When i have it connected to the computer (through USB), my script works fine. However, when I remove the USB connection and try to run the script externally, the controller does not work as I expect it (it moves the servo more times than I specified in my code).

I am using the servo with a syringe to mimic a respiratory curve. I have posted my code.

begin   
    normalBreath
    3000 delay
    smallBreath
    3000 delay
repeat

sub smallBreath
    0 6 acceleration
    150 6 speed
    7250 6 servo
    60 delay
    0 6 acceleration
    150 6 speed
    8000 6 servo
    return

sub normalBreath
    0 6 acceleration
    400 6 speed
    4000 6 servo
    300 delay
    0 6 acceleration
    400 6 speed
    8000 6 servo
    return

I am powering my entire controller off 4 AA batteries. Any ideas what is going on? Maybe the processor is not getting enough power?

Thanks,
Philip

As i suspected, the battery was the cause for the inconsistencies. Should have tried that before this post…I apologize.

Thanks,
