Knob Installation Guide:

Follow these steps to securely attach the knob to the potentiometer (pot) shaft:
- Remove the Plastic Cap:
 - Gently pull off the plastic cap from the top of the knob to expose the screw inside.
 

- Attach the Knob:
 - Slide the brass insert (inside the knob) onto the pot shaft.
 - Ensure the knob is positioned with a small gap between it and the panel where the pot is mounted. This prevents the knob from touching the panel during rotation.
 - Secure the Knob:
 - Tighten the screw inside the knob to clamp the brass insert onto the pot shaft. This locks the knob in place.
 - Replace the Cap:
 - Press the plastic cap back onto the knob to complete installation.
 
 
- 
Safety Notes:
- Always disconnect power before installing or adjusting the controller.
 - Ensure wiring connections (motor and power) are secure using the provided 4mm bullet connectors.

Looks like a great solution
I am modifying and updating the feed roller system on a wood planer machine and it looks like this is going to work out great. I haven't run it in production mode yet but have the motor mounted and have tested the operation. I am really optimistic about this solution. Wish I could upload a picture.

Great low cost motor
I was looking for a modest cost DC motor to control two pumps. This worked great. Really only got reliable rpm down to about 20-25 rpm. Great torque for the price.

Good
Had a little issue with variable speed not working. Once it started, it is working well now
