I bought a few weeks ago a Micro Maestro 6-Channel USB Servo Controller and an Hitec 645MG servo (for a project I’ll talk about in a few into the Project Category).
The Maestro is connected to a Raspberry Pi3b but receives its power voltage through an individual external adapter (5.8V / 2,4A).
In my project, my servo has 2 positions. One is vertical, one is horizontal. I created these 2 positions using the Provided Control Center.
When I power off my whole installation, the servo is usually stopped while the horn is at horizontal position. Then I usually unplug my adapter from current.
But when I replug the adapter and then power ON my installation, there is a slight move of the servo position, just between horizontal and vertical : this is not wanted at all. It behaves like “being suddenly plugged to the current” makes it receive some unwanted moving signal (?).
If I keep the adapter plugged into the current, even with everything not used, than I can power ON everything and the servo doesn’t move.
Anyone would have an idea as where to start my investigation to stop this strange behavior ?
Thanks in advance
