Ssc-32 and max msp

Hi,
Today, I’m trying to play with my ssc32 in max msp.
I’m trying to update 30 servos positions at the same time and at the same speed.
So some sliders are sending a continuous stream of position to each servos.
I did not specified any data, expecting servo to move at their max speed, constantly aiming at their new position.
The problem is that after a few seconds of continuous position stream, the board stops working.
I need to reset my serial component in max and everything restarts…
Here is a sample of what i continuously send:

#1 P1600 , #2 P1650 (…) #30 P1250

It may be time consuming or the buffer may be over loaded, I don’t know.
Does a group command could help? is it resources consuming for the board? If it’s the case, how many milliseconds should I wait before sending new positions?

The fact that I don’t specify any speed could be the issue? it’s possible that servos don’t have enough time to reach their position before new ones are received.
everything was working great and hour long, with fewer servos. (3)

thanks for any precious help. :slight_smile:

The servo positions should not be updated more than every 20mS. Sending positions faster than that serves no useful purpose and will make it difficult for the SSC-32 to work effectively. Also to use the SSC-32 the most effectively, you must group the moves and use a T setting for the move. Make the update time slightly less than the T value and you will have a smooth, seamless, and robust positioning system.
