Why Choose Twetrees 4th Axis Rotary Module
Key Features
- Precision 4th Axis Rotation – Enables engraving on cylindrical and round objects that standard flat bed lasers cannot handle. Perfect for cups, tumblers, wine bottles, rolling pins, and pens.
- Stable Three-Jaw Chuck Structure – Self-centering chuck securely holds round objects from 4mm minimum to 60mm maximum diameter. Firm grip prevents slipping during rotation.
- 4:1 Reduction Ratio – Chuck reduction ratio provides smooth, step-free rotation. Ensures fine detail reproduction on curved surfaces without faceting or stepping artifacts.
- Rust-Resistant Coating – Treated surface resists corrosion and wear. Fine workmanship and sturdy jaws maximize lifespan even with frequent use.
- TTC450 Compatibility – Designed specifically for TTC450 engravers but works with many other CNC and laser engraver systems that support 4th axis control.
Compatibility and Best Use
- TTC450 Laser Engraver – Direct fit for TTC450 machines. Check your controller’s 4th axis support before purchasing.
- CNC Woodworking Engravers – Compatible with CNC routers that support rotary axis. Great for carving spirals, flutes, and bamboo joints on wood cylinders.
- Laser Engraving Cylindrical Objects – Engrave custom text or logos on stainless steel tumblers, glass bottles, acrylic tubes, wooden dowels, and aluminum pipes.
- 3D Cylindrical Carving – Create spirals, thread-like patterns, decorative grooves, scars, and bamboo node effects on round workpieces.
- Bent Pipe and Circle Processing – The 4th axis supports three-dimensional processing of bent pipes and circular profiles (subject to workpiece clearance).
Installation and Setup Tips
- Verify Machine Compatibility – Ensure your CNC or laser engraver controller has a 4th axis driver port. TTC450 users: check that your firmware supports rotary mode.
- Calculate Clamping Length – Maximum clamping length depends on your machine’s working area. Subtract the distance occupied by the chuck kit and top pin kit from total machine travel.
- Secure the Module – Mount the rotary unit firmly to your machine’s bed using T-slots or clamps. The module must be parallel to the X or Y axis for accurate rotation.
- Adjust Center Height – The center height is 50mm. Ensure your laser or spindle aligns with this center point. Shim if necessary to achieve perfect alignment.
- Configure Software Settings – In LightBurn, LaserGRBL, or CNC software, enable rotary mode. Set the correct steps per rotation based on your chuck reduction ratio (4:1). Test with a simple circle before engraving.
Product Specifications
Packing List

Warnings and Safety Notes
- Check machine compatibility – Verify that your CNC or laser engraver controller supports 4th axis rotary operation. TTC450 users should confirm firmware has rotary mode enabled.
- Secure workpiece firmly – Improper clamping may cause the object to slip or become airborne during rotation. Always tighten chuck jaws securely before operation.
- Mind maximum diameter – Do not exceed 60mm clamping diameter. Oversized objects may hit the laser module or spindle, causing damage or injury.
- Center height alignment – Laser or spindle tip must align precisely with the 50mm center height. Misalignment will result in defocused engraving or cutting.
- Reduce speed for heavy objects – Heavy or unbalanced cylindrical objects may cause vibration. Reduce rotation speed and use lower acceleration settings.
- Keep away from moving parts – Do not touch the rotary module while it is in motion. Loose clothing, hair, or jewelry may become entangled.
- Disconnect power during setup – Always turn off and unplug the machine when installing or adjusting the rotary module to prevent accidental startup.
