What’s in the Box: Unboxing and Inspection

Before powering anything on, take a few minutes to verify that everything arrived in good condition and that all components are present. Proper inspection at this stage saves you from interruptions later.

Package Contents

When you open the box, you should find the following items:

• MT400RUL100ProV6 motorized turntable unit (available in White or Black)
• Infrared remote control (requires 2x AAA batteries, not included — please prepare your own)
• USB cable (Type-A to Type-B, for computer software control)
• DC power adapter (input 100-240V AC, output matched to the turntable)
• User manual (quick-start guide with diagrams)

Visual Inspection Checklist

Lift the programmable rotating platform out of the box carefully — remember, this unit itself carries some weight. Check the following:

1. Turntable surface: Ensure the 400mm top plate is free of scratches, dents, or warping.
2. Housing and base: Inspect the motorized turntable stand body for any shipping damage. The unit measures 400mm in diameter and only 70mm in height, so its low-profile design means the internal motor and gear assembly are packed tightly inside.
3. Connectors: Verify that the DC power jack on the side and the USB port are intact and free of debris.
4. Remote control: Insert 2x AAA batteries (not included) and press buttons to confirm the remote responds. The infrared signal emitted from the remote is invisible to the naked eye.
5. Power adapter: Check that the cable and plug are undamaged.

If anything is missing or damaged, contact COMXIM support before proceeding. Do not attempt to disassemble the unit.

Device Setup and Preparation

Setting up this motorized rotating display stand is straightforward. You will need a flat, stable surface and a nearby power outlet. Let us go through the process step by step.

Choosing the Right Surface

Place the turntable on a level, hard surface such as a tabletop, workbench, or photography platform. Avoid soft or uneven materials like fabric or foam, which can cause vibration or tilting during rotation. For product photography and 3D scanning applications, a sturdy table at waist height typically works best.

Surface Requirements

• Flatness: The surface must be level within 1-2 degrees to ensure smooth, wobble-free rotation.
• Load-bearing capacity: The surface itself should support the combined weight of the turntable and your heaviest intended load.
• Vibration isolation: If you are operating near heavy machinery or foot traffic, consider placing an anti-vibration pad beneath the unit.

Power Connection

Once the turntable is positioned, connect the DC power adapter to the power jack on the side of the unit. Then plug the adapter into a standard electrical outlet. The turntable does not contain an internal battery — it requires continuous external power during operation.

Power Specifications

Parameter	Value
Input Voltage	100-240V AC, 50/60Hz
Adapter Output	DC (matched to unit)
Power Cable Length	Approximately 1.5 meters

Tip: Use a surge protector or UPS to safeguard the motorized turntable against voltage spikes, especially in environments with unstable power supply.

Powering On

Locate the power switch on the side panel of the turntable base. Flip the switch to the ON position. You will hear three short beep sounds — this is the built-in self-check confirmation, indicating that the turntable’s control system has passed its internal diagnostics and is ready to operate.

After the self-check beeps, the turntable will begin rotating automatically at the default speed. There is no standby mode — the unit starts rotating as soon as it powers on. Use the remote control to change direction, speed, or rotation mode as needed.

If you do not hear the three-beep self-check sequence, double-check that the power adapter is fully seated in the jack and that the outlet is live. Refer to the Troubleshooting section at the end of this guide if the issue persists.

Remote Control Operation

The included infrared remote control is the fastest way to operate the turntable for most everyday tasks. It gives you direct access to all five rotation modes through dedicated buttons without needing a computer. Let us break down every button and its function.

Remote Control Layout and Button Functions

Direction and Speed Controls

• Clockwise (CW) Button: Initiates clockwise rotation at the current speed setting. Note that pressing this button repeatedly will not change the turntable’s behavior — the turntable continues rotating in the set direction and speed regardless of additional CW presses.
• Counter-Clockwise (CCW) Button: Initiates counter-clockwise rotation at the current speed setting. Similar to the CW button, repeated pressing has no additional effect on the turntable’s state.
• Speed + / Speed – Buttons: Adjust the rotation speed. The adjustable speed turntable range spans from approximately 30 seconds per full circle (fastest) to 78 seconds per full circle (slowest). Each press increments or decrements the speed by one step.
• Start / Stop Button: Starts or halts rotation regardless of the current mode.

Mode Selection — Dedicated Mode Buttons

Unlike basic turntables that use a single button to cycle through modes, the COMXIM remote features dedicated mode buttons for quick, direct access:

• Continuous Mode Button: Activates continuous rotation in the current direction. The turntable spins smoothly without stopping until you press Start/Stop.
• Repeated Step Mode Button: Activates intermittent step rotation. The turntable rotates by the last-selected angle, pauses, then rotates again — repeating automatically.
• Pendulum Mode Button: Activates swing mode. The turntable rotates back and forth between set angular limits.

The remote also includes additional function buttons:

• Lock Button: Locks the remote controls to prevent accidental button presses.
• Save Button: Saves the current configuration settings.
• Set Angle Button: Used in combination with angle keys to configure rotation parameters.
• Set Origin Button: Sets the current position as the reference origin point.
• Return Origin Button: Rotates the turntable back to the set origin position.

Fixed Angle Keys

The remote does not have incremental angle adjustment buttons. Instead, it provides fixed angle keys for quick selection of common rotation angles:

• 1° / 5° / 10° / 36° / 45° / 90° keys — Press any of these to set the step angle directly. For example, pressing the 10° key sets the rotation step to 10 degrees.
• 360/n key — Activates the multi-step mode where the turntable divides a full circle into n equal segments.

When using angle-based rotation modes (such as Repeated Step), the turntable uses the last pressed angle key value as the step angle. There is no separate confirm button — simply press the desired angle key, then activate the rotation mode.

Pro Tip: The 1-degree step accuracy gives you precise control over positioning — essential for a product photography turntable workflow where consistent framing matters.

Using the Remote

No pairing process is required. Simply insert 2x AAA batteries (not included), point the remote at the turntable’s infrared receiver (located on the front panel of the base) within a range of approximately 3-5 meters, and press the desired button. The turntable responds immediately.

Pro Tip: When using the remote control turntable in a bright studio environment, make sure no strong infrared light sources (such as halogen lamps or direct sunlight) are aimed at the receiver, as this can interfere with signal reception. The infrared signal itself is invisible to the naked eye.

Software Control via USB

For users who need more precise control than the remote provides, the USB interface lets you operate the turntable from your computer. COMXIM offers the TurntableX Windows demo software for immediate use, as well as an SDK/API for developers who want to build custom integrations.

Connecting the Turntable to Your Computer

1. Ensure the turntable is powered on using the power switch as described earlier.
2. Connect the USB cable (Type-A to Type-B) between the turntable’s USB port and an available USB port on your computer.
3. Install the CH340 driver (USB to serial adapter) on your computer. This driver is required for the computer to recognize the turntable’s USB interface. You can download it from the COMXIM website.
4. Once the driver is installed, the turntable will appear as a serial (COM) port on your system.

USB Connection Notes

• The USB interface uses serial communication via the CH340 USB-to-serial chip. There are no specific operating system requirements — simply install the corresponding CH340 driver for your OS (Windows, macOS, Linux).
• Use a high-quality, shielded USB cable no longer than 2 meters for reliable data transfer.
• Avoid using USB hubs; connect directly to a port on your computer for the best compatibility.

TurntableX — Windows Demo Software

COMXIM provides TurntableX, a Windows demo application that lets you control the programmable turntable directly from your PC. Once the CH340 driver is installed and the turntable is connected, TurntableX detects the device and gives you a graphical interface for all rotation functions — setting modes, adjusting angles, configuring pause times, controlling speed, and starting or stopping rotation.

TurntableX is especially useful for exploring the turntable’s capabilities during initial setup, testing different rotation configurations before a shoot, or operating the turntable when you do not need a custom-built solution.

CT Command Protocol

Under the hood, the COMXIM turntable is controlled via CT command strings sent over the serial connection. This is the core communication protocol that all software — including TurntableX — uses to talk to the turntable.

This design has an important implication: any software that can send CT command strings to the turntable can control it. You are not locked into a single application. If you have your own photography pipeline, scanning software, or automation script, you can send CT commands directly over the serial port to operate the turntable exactly as you need.

The full CT command protocol is documented in the COMXIM User Guide, which is available on the COMXIM website. The guide lists every supported command, its parameters, and the expected response format.

SDK/API for Custom Development

For developers building deeper integrations, COMXIM provides an SDK/API that wraps the CT command protocol into a structured development framework. With the SDK, you can:

• Send rotation commands (start, stop, change direction, adjust speed)
• Configure all five rotation modes and their parameters (angle, speed, pause duration, repetitions)
• Read status feedback from the turntable
• Integrate with your existing capture or scanning software

Note: COMXIM provides SDK documentation and sample code to help you get started. Contact COMXIM support to request the SDK package for your development environment.

Core Rotation Modes: A Detailed Walkthrough

The MT400RUL100ProV6 offers five distinct rotation modes, each designed for different use cases. Understanding when and how to use each mode is the key to getting professional results from your rotating display stand.

Mode 1: Continuous Rotation

This is the simplest mode — the turntable spins continuously in your chosen direction at a constant speed.

How to Set Up Continuous Rotation

1. Press the Continuous Mode button on the remote, or send a continuous rotation command via the SDK.
2. Use the Speed + / Speed – buttons (or your custom software) to set your desired rotation speed between 30 and 78 seconds per full circle.
3. The turntable rotates until you press Start/Stop.

When to Use Continuous Rotation

• Live streaming and e-commerce video: A slow, steady rotation gives viewers a full view of a product in real time.
• Quick product overview shots: When you need a simple, always-moving display.
• Display and exhibition: Retail counters, trade show booths, and museum displays benefit from smooth, uninterrupted motion.

Recommended speed for live streaming: Set the adjustable speed turntable to approximately 60 seconds per revolution. This is slow enough for viewers to absorb details but fast enough to maintain visual interest.

Mode 2: Single-Step Mode

In single-step mode, the turntable rotates by a specific angle , then stops. You trigger each step manually.

How to Set Up Single-Step Mode

1. Press the desired angle key on the remote (e.g., 10°, 45°, or 90°) to set the step angle.
2. Press CW or CCW to rotate the turntable by that angle. The turntable rotates exactly the selected angle and stops.
3. Each subsequent press of CW or CCW repeats the same angular step.

When to Use Single-Step Mode

• Precise product photography from fixed angles: Rotate the product to an exact position, capture the shot, then step again.
• Inspection and quality control: Examine a specific face or feature of an object at a known angular interval.
• 3D scanning calibration: Position the object at precise angles before triggering a scan.

Mode 3: Repeated Step Mode (Intermittent Rotation)

This mode automates the step-and-capture workflow. The turntable rotates by a set angle, pauses, then rotates again — repeating automatically.

How to Set Up Repeated Step Mode

Using the Remote Control:

1. Press the desired angle key on the remote (e.g., 10°) to set the step angle.
2. Press the Repeated Step Mode button. The turntable begins rotating in the direction it was moving before you pressed the button, stepping by the selected angle each time.
3. The pause duration at each step position is fixed at 4 seconds on the remote control and cannot be adjusted. The turntable continues repeating until you press Start/Stop.

Using TurntableX Software:

1. Open TurntableX and select Step Mode.
2. Set the step angle (e.g., 10 degrees per step).
3. Set the pause time at each position (e.g., 3 seconds — enough time for your camera to capture).
4. Set the repeat count (e.g., 36 steps for a full 360-degree rotation at 10-degree intervals).
5. Press the CW or CCW key in the software to start rotation in the desired direction.

The software gives you full control over the pause duration and repeat count — parameters that are fixed when using the remote.

When to Use Repeated Step Mode

• 360-degree product photography: This is the go-to mode for creating spin sets. Pair it with camera interval shooting for a fully automated pipeline.
• Photogrammetry capture: Capture overlapping images at consistent angular intervals for 3D reconstruction software.
• Batch processing: When you photograph dozens of products per day, saving your step parameters as a preset eliminates repetitive setup.

Pro Tip for 3D Scanning: When using this motorized turntable as a 3d scanning turntable, set the step angle to match your scanner’s angular resolution. A common setup is 1-degree steps with a 2-second pause, yielding 360 frames per revolution.

Mode 4: Pendulum / Swing Mode

Pendulum mode makes the turntable rotate back and forth in an oscillating motion, creating an eye-catching sweeping effect.

How to Set Up Pendulum Mode

Using the Remote Control:

1. Press the desired angle key on the remote (e.g., 45°). This sets the total sweep angle.
2. Press the Pendulum Mode button. The turntable begins oscillating, centered on the pressed angle — for example, if you pressed 45°, the turntable sweeps back and forth across a 45-degree total arc.
3. The turntable starts rotating in the direction it was moving before you pressed the pendulum button.
4. The pause duration at each end of the swing is fixed at 4 seconds on the remote control and cannot be adjusted. The turntable continues oscillating until you press Start/Stop.

Using TurntableX Software:

1. Open TurntableX and select Pendulum Mode.
2. Set the sweep angle (e.g., 45 degrees).
3. Set the pause time at each end of the swing.
4. Set the repeat count.
5. Press the CW or CCW key in the software to start the oscillation in the desired direction.

The software gives you full control over the pause time and repeat count — parameters that are fixed when using the remote.

When to Use Pendulum Mode

• Attractive product displays: The back-and-forth motion draws the eye and is ideal for showcasing jewelry, watches, shoes, and consumer electronics in retail or online settings.
• Video content: Creates a dynamic, attention-grabbing effect for social media clips and promotional videos.
• Limited-space photography: When you cannot fit a full 360-degree setup, a swing shot captures multiple angles in a tight frame.

Mode 5: Multi-step Within One Circle (360/n)

This mode divides a full 360-degree rotation into equal segments. You specify the number of segments (n), and the turntable calculates the angle automatically (360/n degrees per step).

How to Set Up Multi-step Mode

Using the Remote Control:

1. Press the 360/n key on the remote to activate multi-step mode.
2. Enter the number of divisions n (e.g., 8 for eight equal positions around the circle, each 45 degrees apart).
3. The turntable steps through all n positions in one full revolution, pausing at each.
4. The pause duration at each position is fixed at 4 seconds on the remote control and cannot be adjusted.

Using TurntableX Software:

The software offers a convenient shortcut system. TurntableX includes preset shortcut keys that instantly configure and launch common multi-step setups. For example, pressing the shortcut key labeled “4” immediately sets the turntable to step mode at 90 degrees with a 4-second pause and 4 repetitions — and the mode starts running right away, no additional buttons required.

You can also manually configure all parameters (angle, pause time, repeat count) in the software interface for full flexibility. Press CW or CCW to start rotation in the desired direction when using manual configuration.

When to Use Multi-step Mode

• Catalog photography: When you need exactly 4, 6, 8, or 12 evenly spaced product views for an online listing.
• Quick turnaround shoots: Faster than manually programming angles for standard multi-view setups.
• Consistency across products: Every item gets the same angular coverage, ensuring a uniform look across your catalog.

Scenario-Specific Tips for Professional Results

Product Photography with a Motorized Turntable

Using a dedicated product photography turntable setup can dramatically improve both the quality and throughput of your studio work.

Lighting Recommendations

• Position your lights around the turntable, not on it. This prevents cables from tangling during rotation.
• Use a light tent or softbox setup for even illumination, especially with reflective objects.
• If shooting in Repeated Step Mode, ensure your lighting is consistent across all angles — avoid directional shadows that shift as the product rotates.

Camera Settings for Automated Spin Sets

• Use manual mode on your camera to lock in exposure, white balance, and focus.
• Set the camera to interval shooting or tether it to capture software that syncs with the turntable’s pause duration.
• Shoot in RAW format for maximum flexibility in post-processing.

Post-Processing Workflow

After capturing your spin set, import all frames into your preferred software (such as Photoshop, GIMP, or dedicated 360-product-view platforms like WebGL viewers). Batch-process the images for consistent exposure and color, then export as a sequence or interactive viewer.

3D Scanning with the MT400RUL100ProV6

As a 3d scanning turntable, this unit provides the stable, precise rotation that photogrammetry and structured-light scanners demand.

Setup Best Practices

• Place the turntable on a vibration-free surface away from direct sunlight (which can interfere with some scanners).
• Apply matte spray or powder to highly reflective or transparent objects before scanning.
• Use Repeated Step Mode with a 1-degree step angle and a pause duration matched to your scanner’s capture time.

Software Integration

For advanced users, the programmable turntable with SDK support allows direct integration with scanning software. You can use TurntableX for quick setup and testing, or leverage the CT command protocol to send rotation commands from your own scripts and applications. The SDK provides a structured framework for building fully automated capture pipelines. Contact COMXIM for SDK documentation and the full CT command reference.

Live Streaming and E-commerce Video

A motorized rotating display stand adds a professional, dynamic quality to live product demonstrations on platforms like Amazon Live, TikTok Shop, or Shopee Live.

Streaming Setup Tips

• Position the turntable centered in your camera frame with adequate background separation.
• Use Continuous Rotation mode at a slow speed (60-78 seconds per revolution) so viewers can see the product clearly.
• If your streaming software supports it, connect the turntable via USB and use TurntableX so you can switch between rotation modes on the fly — for example, switching to Pendulum Mode to highlight a specific feature.

Engagement Strategies

• Alternate between continuous rotation and single-step pauses to create visual variety.
• Use the remote control turntable functionality to make real-time adjustments during the stream without leaving the camera frame.
• For multi-product streams, use the Save button on the remote to store your rotation presets so you can switch configurations between products in seconds.

Daily Maintenance and Troubleshooting

Routine Maintenance

Proper care extends the life of your electric turntable and keeps rotation smooth and accurate.

Cleaning

• Wipe the turntable surface with a soft, dry cloth after each use. Avoid abrasive cleaners or solvents that could damage the surface finish.

Mechanical Care

• Do not exceed the rated load capacity: 100kg for step rotation and 225kg for continuous rotation. Overloading strains the motor and gears, leading to premature wear.
• Avoid sudden impacts or dropping heavy objects onto the platform, which can misalign the internal gear assembly.
• Store the turntable in its original packaging or a protective cover when not in use for extended periods.

Electrical Care

• Always power off the turntable using the side switch when not in use.
• Unplug the power adapter during lightning storms or extended periods of non-use.
• Do not wrap the USB or power cable tightly around the unit during storage — use loose coils to prevent wire fatigue.

Troubleshooting Common Issues

Turntable Does Not Power On

• Verify the power adapter is connected securely to both the turntable and the outlet.
• Test the outlet with another device to confirm it is live.
• Check the power adapter’s indicator light (if present). If it is off, the adapter may need replacement.

Remote Control Not Responding

• Replace the AAA batteries in the remote (uses 2x AAA, not included with the unit).
• Ensure you are within 5 meters of the turntable and pointing directly at the infrared receiver.
• Remove any obstacles between the remote and the receiver.
• Check for infrared interference from nearby lighting or equipment.

USB Connection Not Detected

• Try a different USB cable and a different USB port on your computer.
• Reinstall the CH340 driver (USB to serial) from the COMXIM website.
• Restart your computer with the turntable connected and powered on.
• Check Device Manager for any unrecognized devices or driver conflicts.

Uneven or Jerky Rotation

• Ensure the turntable is on a flat, level surface.
• Verify that the load is centered on the platform and does not exceed the rated capacity.
• Reduce the rotation speed — very high speeds with heavy loads can cause the motor to struggle.
• If the issue persists, contact COMXIM technical support for further diagnosis.

Inaccurate Step Angles

• Recalibrate the turntable using the calibration procedure in the user manual.
• Ensure firmware is up to date — check the COMXIM website for the latest version.
• If accuracy issues continue after recalibration, the internal encoder may require service. Contact COMXIM support.
