Hello, I have two MG90s servos that are going in an iron Man helmet to open the faceplate and close the faceplate. One servo runs absolutely fantastic, two servos runs absolutely fantastic. Power doesn’t fluctuate. The problem is one servo goes one way the other server goes the other way so it tweaks everything out. I thought that just swapping the positive and negative for one of the servos would accomplish my goal of them both going the same direction but it does not. I’m a noob when it comes to this so am I missing something? Do I need an additional relay? Thank you in advance.
You will need two servo trigger boards to do this, both boards will work with a single trigger.
Alternatively, you could modify the servo for reverse operation, but it’s much easier to just use a second servo trigger.
How would I modify the servo? It would be much easier to do that as I have a limited space. Thank you for your help
You’d have to disassemble the servo and reverse the wires to the motor and feedback potentiometer.
Thank you for that, I accomplished what I wanted. Now. I’m running into the problem that the servo trigger only goes about half of the travel distance of the servo. I have adjusted a&b to their max and I get 1/3 to 1/2 of the servos movement.
If I recall correctly, the servo trigger only allows for 90 degrees of movement.
