Step-rotation mode is for applications requiring precise stops at specific angles, such as 3D scanning or automated photography, where the maximum load is 150kg. For optimal service life, it is recommended to operate at 80 percent of the maximum rated load.

Two Control Methods: Step-by-Step Practical Tutorial

The UT500RUTYL150ProV6 offers flexible control options to suit different workflows. Below are detailed step-by-step instructions for each method.

Method 1: USB Wired Control via Windows Computer

This is the recommended method for precise and programmable control.

Step 1: Download and install the CH340 USB driver from the official ComXim website. After installation, connect the turntable to your computer using a USB Type-B cable.

Step 2: Power on the turntable and turn on the power switch. Open Windows Device Manager and verify that a new COM port appears under Ports, typically labeled as USB Serial CH340.

Step 3: Download the TurntableX software from the ComXim download page. Extract the files and run the executable. No installation is required.

Step 4: In the TurntableX interface, select the correct COM port from the dropdown menu and set the baud rate to 115200. Click the Connect button.

Step 5: Once connected, the status indicator shows a double-headed arrow. Click the Device Name button to read product information and confirm successful communication.

Step 6: You can now set rotation parameters such as mode, angle, speed, and pause time, then click start to begin operation.

Method 2: Infrared Remote Control for Quick Operation

The included remote control provides immediate access to essential functions.

Step 1: After powering on the turntable, point the remote control toward the infrared receiver on the device.

Step 2: Press the Continuous Rotation Mode button to start continuous spinning. Use Speed Up and Speed Down buttons to adjust rotation speed. Press the Clockwise or Counterclockwise Direction buttons to change the spin direction. Press Start or Stop to pause or resume movement.

Step 3: For step-by-step rotation, press the Set Angle button to define an angle value, then press the Repeated Step Mode button. The turntable will rotate by the set angle, pause for 4 seconds, and repeat this cycle continuously.

Step 4: To use the multi-step within one circle mode, simply press one of the preset number buttons. Each press rotates the turntable by 360 divided by n degrees, pauses for 4 seconds, and repeats until a full circle is completed, automatically stopping at the starting position.

Step 5: Press the Save button to store current settings into the turntable’s internal Flash memory. These parameters will be loaded automatically on the next power-up.

Hardware Zero-Point Setting and Detection

• Precise origin positioning is crucial for 3D scanning and multi-angle photography. The UT500RUTYL150ProV6 features a physical reference mark, often indicated by a marking point on the turntable surface, for hardware zero-point detection.
• To set the hardware zero point, first power on the turntable and allow it to initialize. Use the infrared remote or software to manually rotate the turntable until the reference mark aligns with the fixed indicator on the device frame. Press the Set Origin button on the remote, or send the CT command CT+SETZERO() via the USB serial interface, to register the current position as the zero point. To return to this position at any time, press the Return to Origin button or send CT+TOZERO().
• For a more automated approach, use the CT+GOTOMARK() command supported by firmware V2R03C02 and later. The turntable automatically rotates to the hardware sensor’s zero position and sets it as the new reference. On completion, it reports back to the host computer with the event message CR+EVENT=TB_MARK, confirming the operation. This feature ensures that every scanning session starts from the exact same position, dramatically reducing post-processing alignment work.

Weight Detection Function

• The UT500RUTYL150ProV6 integrates a high-precision load cell for real-time weight measurement. This function is particularly useful for quality control, material testing, and ensuring that the object placed on the turntable does not exceed the rated load capacity.
• The weight sensor provides readings with an accuracy of plus or minus 0.25kg. To use this function, connect the turntable to a computer via USB and open TurntableX software or any serial terminal. Send the CT+GETWEIGHTBYKG() command, and the turntable returns the current load in kilograms, for example, CurLoad(kg)=15.5kg.
• The tare function allows zero calibration for net weight measurement. Place the empty platform or container on the turntable, then send CT+SETWEIGHTSCALE(0,0). This sets the current weight as zero. When objects are added later, only the net weight is displayed. Multiple calibration points can be configured using CT+SETWEIGHTSCALE(num,weight) for enhanced accuracy. The factory already provides pre-calibration, so most users can use this function directly without additional setup.

Complete Secondary Development Guide

For developers and R&D teams, the UT500RUTYL150ProV6 offers powerful programmability through the USB serial interface. This transforms the turntable from a simple rotating base into a fully integrated component of automated systems.

Dual Development Interface

The USB interface virtualizes a traditional COM port after installing the CH340 driver. This means any programming language that supports serial communication can control the turntable, including C, C++, Python, C, Java, and more. The physical USB connection provides reliable wired communication, ideal for laboratory and industrial environments.

Customizable Programming Capabilities

The turntable uses a unified CT command set, where CT stands for Control Transmit. Each command starts with CT and ends with a semicolon, using plain text strings. Common control commands include CT+START to initiate a complete rotation sequence, CT+TURNINGLE to execute a single specified angle rotation, CT+SETZERO to designate the current position as the reference zero point, CT+TOZERO to return to that zero point, CT+GOTOMARK to rotate to the hardware sensor zero position, and CT+GETWEIGHTBYKG to retrieve real-time weight data.

The command system also includes query and response mechanisms. When the turntable receives a valid command, it returns CR+OK. When an action completes, it sends CR+EVENT=TB_END. Error responses include CR+ERR plus a code, such as CR+ERR=70 indicating a non-numeric parameter.

Suitable for R&D Personnel

This product is ideal for automation engineers, robotics researchers, and software developers who need to integrate precise rotation into larger systems. Use cases include automated quality inspection lines, custom 3D scanning rigs, synchronized multi-camera capture systems, and laboratory test stands requiring repeatable motion sequences. The CT command structure is straightforward, allowing rapid prototyping and deployment.
