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.
