The B servo does not work at all. The A servo does not work with power off but works with power on, the opposite of the instructions. Also when I continuity test the switch, I get a light between the two switch prongs when switch is off. I triple checked the wiring to the card and, the supply voltage. I changed the switch, I tested the servo (good) and even changed the servo. The first unit worked fine. This is my second unit and I have ordered a third. Help appreciated. Thanks

The “B” is the endpoint setting **https://youtu.be/lcSA3hWZ2zg

How are you triggering the board? I don’t see a button attached.
A 4.5V, 3XAA power supply does not meet the specs for most servos. 4xAA would be a much better choice.
After looking at the picture I sent realized that I left out the trigger switch, YellowDog also caught it. I tested the correct setup at 5 volts and the servos run fine. Sorry for the stupid mistake. Thanks for everyone that helped
