Machine wiring

1. Please insert the spindle motor cable into the corresponding port on the interface board at the back of the Z-axis module.
2. Plug the X-axis limit switch cable and the main control cable into their corresponding ports on the adapter board.
3. First, connect the limit switch cable to the limit terminal on the Y-axis. Then, insert the X-axis terminal into the corresponding port of the X-axis motor.
4. Align the antenna with the hole, and then tighten the nut clockwise.
5. Check the direction of the terminals to ensure correct installation and avoid short circuits when inserting the control box.
6. Ensure that the Y1 and Y2 terminals are correctly connected to the corresponding ports of the motors.
7. It is recommended to place a wooden board larger than 1.3xl.3 mat the bottom of the machine to enhance its stability.

Motherboard

• Please confirm that the motherboard wiring is correct, as shown in Figure
• Ensure that the wiring is not loose after installed correctly.

Power supply

• Please check if the cables are loose and then reconnect them.
• Check if there is voltage at the power socket interface and if there is current at the power input.
  If there is voltage but no current, it indicates that there is a problem with the power source.
• Check if the power socket is loose and if the power indicator light is on. Please check if the power indicator light on the casing is lit. If the light is on but the machine does not work properly, check if the indicator light on the motherboard is lit. If the indicator light is not on, the output cable may be loose, or there may be an issue with the motherboard.

Screen

• As shown in Figure 2, please check if the screen cable is loose and retighten it, or change the order of the wires and restart.
• Loose Screen Cable: During transportation, the machine may experience vibrations, which can cause internal connectors to become loose, leading to poor contact or no contact at all. At this point, the machine’s screen may turn white and fail to function properly. Please first check if there are any issues with the cables.
• Motherboard or Screen Issue: If the screen cable is functioning properly, then the issue may lie with the motherboard or the screen itself. If you have multiple machines, you can replace the “faulty” screen with one that displays normally. If the good screen works properly, then the original screen is at fault. If not, the issue is with the motherboard. If you encounter this problem, please contact after-sales customer service.

Motor

• First, check if the motor wires are securely connected to the motor terminals and the motherboard port. If there is any looseness or poor contact, reinsert the power supply and then test the power.
• Swap the position of the motor. If there is still no response after reinserting it, you can test by replacing
  the faulty motor with a working one at the motherboard port. After the test, determine the cause of the motor failure (A. Motor wiring issue B. Driver issue C. Motor issue).
• Motor Wire Issue: After confirming that the motor is not faulty, please swap the problematic motor wire on the motherboard with a working motor wire, and then perform the test. If it works without issues, then the problem is with the motor wire. If it still does not work, please check the driver.
• Note: Adjust the motor wiring on the motherboard. As shown in Figure 1, if there is a Y-axis vibration, you can swap the faulty motor wire with the good motor wire (the Y/XZ/E-axis motor wires are good) at the port. At the same time, ensure that the motor wire matches the corresponding motor. After powering on, test by moving the axis to check its functionality.
• Driver Issue: After confirming that the motor and motor wires are not faulty, recheck the motor driver. The driver may be problematic and may need to be replaced with a new one.

TF card issue

• TF card Issue: How to determine if there is a problem with the TF card? First, check if the card can be used normally on a computer. if the TF card works without malfunction on the computer, save the files to the computer and format the card. Place the card into the machine for testing. If it is not recognized after powering on, it indicates that there is a problem with the TF card and it needs to be replaced.
• Check if the card slot is loose. Long-term use of the card slot may cause the card holder to wobble, leading to poor card reading. To solve this issue, you may need to replace the card holder with a new one. Sometimes the card may be inserted into the slot briefly and then suddenly stop responding. You can quickly insert and remove the card several times, then try inserting it after turning off the power. After that, clean the card with some alcohol, insert it into the slot, and insert it several times to see if it can be used normally after cleaning.
• Oxidation of the TF card chip. You can try applying a small amount of alcohol to the SD card, then insert the card into the slot and insert it several times. After cleaning, check if it can be used normally.
