Setup and Installation
1. Crown and Drive Adapter Selection
The correct crown and drive adapter are crucial for proper motor function with your rolling tube. While we provide adapters based on your order, please be aware of the following:
- Different countries may have varying internal structures for rolling tubes, even with the same outer diameter.
- You may need to modify the provided crown and drive adapter to fit your specific tube.
- Alternatively, you can source compatible components from your local market or use 3D printing if you have the capability.
- If your existing crown and drive adapter are in good condition and compatible, it is often best to reuse them.
