Complete Tutorial for the Programmable Motorized Turntable MT500RUWL100ProV6: 50cm Heavy-Duty Platform Empowering 3D Scanning and Industrial R&D

In 3D modeling, cultural heritage digitization, product photography, and industrial automation, turntables are essential tools for workflow efficiency. However, conventional motorized turntables suffer from three critical limitations: insufficient load capacity prevents scanning of large objects, inadequate rotational accuracy compromises model stitching quality, and the lack of open interfaces blocks integration into existing systems. The ComXim MT500RUWL100ProV6 Programmable Motorized Turntable is purpose-built to overcome these challenges—it combines a 50cm heavy-duty platform with USB+Wi-Fi dual-interface SDK support, making it ideal for 3D scanning studios, industrial R&D departments, and automated commercial photography teams.

1. Complete Product Specifications

1.1 Core Dimensions and Load Capacity

The MT500RUWL100ProV6 features an industrial-grade dual-motor drive architecture, which effectively eliminates torque imbalance and vibration under heavy loads compared to single-motor solutions, ensuring smooth operation of the large-diameter platter. The turntable measures 50cm (19.7 inches) in diameter and approximately 10cm in height.

Load capacity must be distinguished between two modes:

• Continuous Rotation Mode: Maximum load 225kg (500lbs) — suitable for continuous display, live streaming, and inline inspection scenarios
• Step Rotation Mode: Maximum load 100kg (220lbs) — suitable for 3D scanning and product photography that require precise positioning and intermittent pauses

The difference between these two load ratings stems from the frequent starts, stops, and positioning accuracy demands placed on the motor in step mode. It is recommended to operate at 80% of the rated load in step mode to extend the product’s service life.

1.2 Rotation Speed and Power Supply

• Speed Range: 35~95 seconds per revolution (adjustable)
• Control Methods: USB PC software + Wi-Fi mobile APP + infrared remote control

1.3 Five Rotation Modes

The device integrates five professional rotation modes, covering everything from simple display to complex automated scanning workflows:

. Continuous Rotation Mode: Rotates continuously at the set direction and speed until manually stopped. Suitable for live streaming and dynamic displays.

. Single-Step Mode: Rotates by the set angle and then stops automatically. Suitable for precise positioning or spot inspection.

. Multi-Step Within One Circle Mode: Rotates by set angle → pauses → repeats until completing a full 360° revolution and returning to the starting position. The system automatically calculates the step angle (e.g., setting 8 steps means 45° per step). This is the standard mode for product photography.

. Repeated Step Mode: Rotates by set angle → pauses → repeats, cycling continuously until manually stopped. Suitable for batch inspection or time-lapse shooting.

. Pendulum (Swing) Mode: Swings back and forth around the current center position by the set angle. Suitable for dynamic displays or specific scanning paths.

3. Complete Secondary Development Guide

The core value of the MT500RUWL100ProV6 lies in its open secondary development interfaces: USB virtual serial port and Wi-Fi TCP Socket dual channels, combined with a unified CT command set, allowing developers to write custom control software in any programming language.

3.1 Dual Development Interfaces

USB Interface (Virtual Serial Port)

• The operating system recognizes the USB connection as a COM port
• Supported languages: C#, Python, C++, Java, etc. (via serial port libraries)
• Communication parameters: baud rate 115200, 8 data bits, 1 stop bit, no parity

Wi-Fi Interface (TCP Socket)

• The turntable acts as an AP hotspot with fixed IP: 192.168.181.181, port: 8181
• Supported languages: any programming environment that supports TCP Socket
• Connection password: 88889999

3.2 CT Command Programming Examples

All CT commands start with CT+ and end with ;. After execution, the turntable returns feedback messages (starting with CR+), allowing developers to determine command execution status.

Example 1: Single Rotation Control

text

CT+TURNSINGLE(1,11.25);

Meaning: Rotate 11.25° counterclockwise and then stop

Example 2: Wi-Fi Connection Pseudocode (Python)

python

import socket
s = socket.socket()
s.connect(("192.168.181.181", 8181))
s.send(b"CT+START(0,1,1,36,4,10);")

3.3 Heartbeat Mechanism and Feedback

The device has a heartbeat mechanism enabled by default, sending a # byte every second to maintain the connection. If no data or CT command is received for 3 consecutive seconds, the turntable enters a heartbeat loss state and sends a ## notification. Developers can monitor heartbeat packets in their software to track connection status in real time.

4. System Compatibility and Troubleshooting

4.1 System Compatibility

Windows: Full support with the official TurntableX software (Windows 10/11 recommended)

Android: The official TurntablePlus APP is a demo version; some Android models have compatibility issues. The source code has been open-sourced, allowing developers to adapt it themselves.

iOS: No official APP currently; developers can build their own via Wi-Fi TCP Socket.

Linux/macOS: No official software, but secondary development is possible by sending CT commands via serial port or Wi-Fi.

4.2 Common Troubleshooting

No COM port appears in Device Manager after USB connection: CH340 driver not installed or installation failed. Re-download and install the driver, and check if antivirus software is blocking it.

TurntableX displays “?” or “X” after connection: Wrong COM port selected or baud rate mismatch. Unplug and re-plug the USB cable to confirm the new COM number, and ensure the baud rate is 115200.

Cannot find the turntable hotspot via Wi-Fi: Turntable not powered on or Wi-Fi module not initialized. Wait 10 seconds after power-on before searching; verify the model name contains “W”.

No internet access after Wi-Fi connection (exclamation mark shown) : The turntable hotspot is for point-to-point control only and does not provide internet access. This is normal; do not disconnect.

Android APP cannot detect the device: System version incompatibility or missing permissions. Check if location permissions are granted; try another Android device.

Remote control buttons have no response: Battery depleted or IR path blocked. Replace the battery; ensure the remote is aimed at the IR receiver window.
