Hi,
I'm hoping for some help getting my test servo to work. I have a Raspberry Pi Zero W controlling a servo via GPIO 4. My setup works for the micro servo's but not for any of the other digital servo's I have.
I've attached a picture of how my set up is currently structured. In this setup I have a TD-4212MG digital servo attached to a 7.2V external power supply just to ensure it is not a power issue:

Running the code below doesn't cause the servo to move at at:
However, when I use a micro servo (shown below) with the same code above it works fine:

Using the same code with any of my bigger servos (again see below) do not seem to work at all):

Can anyone help me understand what I am doing wrong?
