USB Secondary Development for ComXim Motorized Turntable – A Complete Developer’s Guide
If you’re building a 3D scanning system, product photography rig, or automated rotating display, the ComXim motorized turntable is one of the most reliable and developer‑friendly platforms you can use. More than a standard electric turntable, it is a fully programmable turntable with SDK that lets you implement custom control via USB for professional automation. This guide is written for English‑speaking engineers, makers, and developers, with clear, practical steps and smooth integration of industry keywords.
Why Choose the ComXim Motorized Turntable for Development?
The ComXim unit is far more than a basic rotating display stand or display turntable. Built as a robust motorized electric turntable with a low‑speed high‑torque motor and strong load capacity, it serves many professional roles:
- 3D scanner turntable / 3D scanning turntable for 3D modeling
- photography turntable for product shooting
- rotating product display for retail and exhibitions
- large heavy‑duty turntable for industrial use
- motorized lazy susan for automated showcasing
It uses the CH340 USB‑to‑serial chip, which creates a virtual COM port on your computer. Combined with its clean ASCII command protocol, you can build stable, custom control with minimal code.
Before You Start: Preparation
Hardware Setup
Use a ComXim motorized turntable model that supports USB (marked with “U”). Connect it to your computer with a standard USB 2.0 Type‑A to Type‑B cable. Power the unit using its external power supply; the built‑in power management ensures safe working voltage and low standby power consumption—ideal for long‑running 360‑degree rotating turntable applications.
Driver Installation
Install the CH340 driver so your PC recognizes the virtual serial port. After installation, you will see the assigned COM port (such as COM3) in Windows Device Manager.
Tools & Resources
- Serial debugging: SSCOM Tool or Windows Serial Tool
- Web‑based control: ComXim Web Device Console
- Official support: ComXim SDK, Development Kit, Demo Software, Android Demo App
- Documentation: Developer Help Center and Developer Resources
These tools help you complete API integration and control your rotating platform with ease.
Core Serial Communication Settings
For stable communication, use these fixed parameters:
- Baud rate: 115200
- Data bits: 8
- Parity: None
- Stop bits: 1
- Flow control: None
The COM port is exclusive, ensuring clean real‑time control without interference.
How the ComXim Control Protocol Works
The turntable uses command‑based control. You send a control command string, the firmware performs command parsing, and runs parameterized commands with real‑time command execution. It also includes a complete command feedback mechanism:
- Status feedback confirms command reception
- Response data includes angle, error, and event information
- Rotation status and position feedback keep you updated in real time
Rotation Functions You Can Implement
With the full instruction set, you can control nearly any motion:
- Rotation speed control and rotation direction control
- Fixed angle rotation and step angle rotation
- Continuous rotation and bidirectional rotation
- Clockwise / counterclockwise rotation
- Positioning rotation and precise position control
- Origin point / home position support, including return to origin
- Absolute position and relative position movement
The turntable reports current angle data and provides a clear rotation completion signal—perfect for 3D scan turntable and photography rotating platform projects.
Essential Development Commands
1. Single Fixed‑Angle Rotation
CT+TURNSINGLE(0,45.0);
Rotates clockwise 45 degrees and stops, ideal for rotating product display.
2. 360° Automatic Photo/Scanning
CT+START(0,1,1,15,2,24);Clockwise, stepping mode, auto shutter, 15° per step, 2s pause, 24 cycles.
Built for photography turntable rotating platform and 3D scanner turntable use.
3. Immediate Stop
CT+SETSTOP();
4. Save Settings (Power‑Off Memory)
CT+SAVECONF();
Enables persistent parameter storage and power‑off memory for reliable repeated use.
Quick Environment Test (1 Minute)
