I made more progress on the cat feeder tonight!
I attached the motor to the back, and the shaft now goes thru and connects to the original (modified) plastic shaft from the dispenser.
The lid has an ultrasonic distance sensor pointing down at the food to be able to tell how much is left in the chute.
There's a button on top to be able to manually dispense a dose.
Lastly, I added a terminal block to connect the wires from the scale for easier mounting to the processor later.
Next up, I need to start connecting all the components to the circuitry! The load cell amplifier, stepper motor driver, and finally the esp32 controller. Then it'll be time to write some software!
