Safety Information
Warning
• This machine works with lasers which can lead to serious injuries or property damage if used improperly:
• DO NOT operate lasers around combustible or explosive materials.
• DO NOT place bodily parts in the path of the laser.
• ALWAYS wear appropriate personal protective equipment such as protective eyewear when
operating lasers. It is also recommended to secure the worksite or erect protective screens
around the laser path to prevent injury to passersby.
• DO NOT allow children or individuals with impaired physical or mental capacities to operate this machine without strict
supervision and training.
• The working area MUST be equipped with appropriate fire fighting equipment.
• Certain materials can emit gases or radiation when exposed to lasers. It is recommended to research your working
materials before exposing them to the laser so appropriate precautions and equipment can be used.
• DO NOT open the control cabinet or other components while the machine is in use.
• DO NOT leave the machine unattended when it is operational.
• DO NOT operate this machine in overly hot or humid environments.
• DO NOT assemble or disassemble this machine without proper training.

Installation
Operation
2
1. Install the autofocus sensor on the laser head, making sure the bottom of the sensor is 5–10 mm lower than the
bottom of the laser head.
2. Install and affix the motor in the hole near the Z-axis lifting transmission belt at the bottom of the engraving
machine. If the transmission belt uses a belt, use the belt connector. If the transmission belt uses a chain, use the
gear chain connector.
3. The motor is a two-phase 4-wire motor. Use a multimeter to confirm which wires are A+, A–, B+, and B– although
these are usually color coded red, green, yellow, and blue respectively.
Connect the wiring according to the circuit diagram below.
4. Connect the 4 wires of the motor to the A+, A–, B+, and B– ports of the driver.
5. Connect the power cord of the driver to the 24V DC port of the switching power supply.
6. Connect PUL+/– and DIR+/– of the driver to the corresponding ports of the Z axis on the motherboard.
7. Connect the autofocus sensor to the CN2/CN3 designated position on the motherboard.
8. Confirm that SW1–SW8 of the PA settings on the side of the driver are set to the following positions:
Connect the computer with your copy of RDWorks V8 to the engraving machine. Open the software interface and
enter the factory settings. Adjust the Z-axis and/or U-axis parameters. Set the step length to 0.40000. The home offset
should be the focus height after the autofocus is triggered. You can use the focal length ruler to help determine this
distance and fill in the value.

After the settings are complete, select the autofocus function on the laser engraver control panel menu and test it.
Maintenance
• Periodically clean the field lens of the laser, especially if the engraving quality becomes noticeably poorer.
• Periodically clean the workbench with 75% isopropyl alcohol.
• Remove any dust that accumulates anywhere on the machine before and after each use.
• Periodically confirm that all screws and bolts are fastened properly and tighten any that has become loose.
