Slow down the servos

Support Servo controllers and servos
1

I’ve been trying to slow down the servos for some time. They’re supposed to slow down, too. They move much too fast. But no matter what value I enter, it doesn’t work. When I move the controller and the dot appears afterward, it seems to be working correctly. However, that’s not happening in the actual execution. The servos don’t slow down. Am I always forgetting something?

Hello.

I do not see any issues with your Maestro settings. However, it does look like most of your servos are making fairly small movements. You might try configuring much lower speeds (e.g. 3 instead of 50) and see if that is more appropriate for your application.

Please note that the speed and acceleration settings will not be used for the first movement after a servo is activated (for example, when the Maestro boots up), but they should apply to all subsequent movements.
