This is a simple high torque DC motor drive housing built to link into the A1 Poop Conveyor. Soldering required for wiring motor and permanent DC jack unless you find some tiny wire plugs.

This box holds a standard JGY 370 motor. I used a 12 volt 10 RPM version. As for the RPM, you want a 6 or 10 RPM motor.

The speed is controlled with an Aledeco PWM Low Voltage Dc 1.8V - 12V 2A Motor Speed Controller. Also functions as a power switch. 1.3x1.3 inch board. Mounts using knob nut.

The small hole in the back is for a 5.5mm DC barrel Jack.

I also used a 12V 1A DC wall adapter.

Center of output shaft is approx 30mm (with base and feet installed).

Assembly:

The motor is sticking out of the back of the box for cooling. I made the rear hole for it uncomfortably large to ease installation.

1. Solder wires to motor tabs. Cover tabs with tape, fold wire over motor and put tape around the motor housing with the wires running down the back side (opposite of the output shaft). The tape will hold the tape attached to the back of the motor and hold the wiring down. Continue wrapping single lines of tape down to the gear box for a clean look. if you don't care about clean then just wrap it.
2. Due to the tight space, put the motor in first through the two holes and then slide the motor spacer around the output shaft.
3. Check positive side of DC jack with continuity mode on multi-meter, Solder (not the motor, just some loose wire) wires then Install.
4. Wire PWM controller. from DC jack to power + and - on PWM Controller. Wire in the motor to the PWM. If the motor runs in reverse (was the case for me), Wire it in reverse (+ to -) to the PWM.
5. Install coupler to output shaft until it is flush with the coupling surface.
6. Install base
7. Add 2mm thick feet to base
8. Attach to Poop Conveyor.

If you want, you can use an interval timer to only run the belt occasionally. Otherwise a momentary switch can be mounted on the x axis to be pressed during filament purges. Just wire it in line with any wire.
