One, one or three axes do not move or move abnormally
1. The control card is loose or faulty; 2. The corresponding axis of the drive is faulty; 3. The corresponding axis stepping motor is faulty; 4. The corresponding coupling is broken or loose; 5. The corresponding screw is broken. Or the screw nut is faulty; 6. The corresponding shaft slips quickly; 7. The number of subdivisions and current of the driver are different from those in the software;
Second, the z-axis is out of control
1. The control card is loose or faulty; 2. Static interference; 3. The z-axis motor line is faulty; 4. The file path is incorrect; 5. The inverter interferes; 6. The computer system has a problem or a virus; 7. The operation error
Third, there is an error
1. The control card is loose or faulty; 2. The drive is faulty; 3. The stepper motor is faulty; 4. The static electricity is disturbed; 5. The motor line is faulty; 6. The data line is faulty; 7. The path is wrong; 8. The coupling is broken or Loose; 9, processing speed is too fast; 10, computer system problems or viruses
Fourth, woodworking engraving machine carvings vary in depth
1. The control card is loose or faulty; 2. The step is close to the motor fault; 3. The driver fault or current subdivision is inconsistent with the software setting; 4. The z-axis motor line is faulty; 5. The spindle motor is faulty; 6. The inverter interference or data setting Incorrect; 7, static interference; 8: computer virus or system problem
Five, chaotic
1. Control card failure; 2. Inverter interference; 3. Incorrect file path; 4. Static interference; 5. Software setup problem; 6. Driver failure or current subdivision setting is incorrect; 7. Data line failure; , the computer has a virus or system problem
Sixth, the bottom is not flat
1. The main shaft and the table are not perpendicular. Need to be corrected; 2, the knife has a problem; 3, the control card has a problem; 4, the Z-axis drive has a problem
Seven, the spindle stops
1. Internal short circuit of the spindle; 2. Current shielding; 3. Incorrect parameter setting of the inverter or its own fault; 4. Fault of the control card; 5. Short circuit of the main axis or data line
Eight, the spindle rotation sound is not normal
1. The inverter is set incorrectly; 2. The spindle does not turn; 3. The spindle itself has problems.
Nine, the opposite direction when walking or returning to the mechanical origin
1. Change the file in Notepad; 2. Modify the wiring method of the inverter; 3: Turn the direction out in Weihong Software.
Ten, the machine can not return to the mechanical origin
1. The direction is opposite; 2. The control card is faulty or loose; 3. The limit switch or data line is faulty; 4. The drive is faulty; 5. The step is close to the motor fault.
Eleven, the spindle can not automatically turn or stop
1. Control card failure; 2: Inverter failure
Twelve, when opening the software, the computer prompts "Failed to open the card, please check the card" prompt
1. Check if the driver of the board is installed, or replace the board with a PCI slot; 2. Reinstall the two data cables to check if there is any broken needle; 3. If there is a problem with the board, replace it. Board.
Thirteen, when opening the software prompt: three-axis alarm, initialization error number four
1. Check if the two data cables of the computer and the machine are connected. 2. Check whether the fuse of the adapter board in the control box is burned and replace the fuse. 3. Check whether the 85V power supply is normally powered.
14. Misalignment or incorrect size when engraving
1. Check whether the path of the engraving software is correct or not. 2. Check the gap size of the screw and the tightening screw of the polished rod. 3. Check the setting of the software parameters correctly.
15. When the X-axis is walking a certain section, the Z-axis does not raise the knife.
1. Check whether the Z-axis motor is running normally, the power and the current of the drive or its own fault; 2. Check if the Z-axis motor line has poor contact or intermediate disconnection.
Sixteen, the spindle motor does not rotate or reverse
1. Check the setting of the parameters of the inverter; 2. Whether the signal line of the inverter is reversed.
Question 1: 
Seventeen, there is a sickle phenomenon
1. The power of the Z-axis motor is not enough, the coupling is loose; 2. The current of the Z-axis drive is too small, or the signal line is wrong.
Eighteen, when the software is turned on, the axis is closed.
1. The problem of the driver or the poor connection of the computer output signal line; 2. The motor line is in poor contact.
Nineteen, the limit phenomenon occurs during the engraving process
1. Check if the engraving path exceeds the engraving range; 2. The soft limit set by the parameters in the software.
20. The machine is not powered when it is turned on.
1. Check if the start button wire is connected and the button is burnt out; 2. Check if the AC contactor is short-circuited or burned out.
Twenty-one, when the button moves, the axis only goes in one direction.
1. Check if the optical line is working properly and whether the line is in good contact; 2. Check if there is any solder joint in the motor circuit.
Twenty-two, the sending software can not be opened normally, the engraving thing is deformed.
1. Reinstall the new system and software; 2. Check if the X and Y axis screw and screw are loose; 3. The carving knife has problems.
Twenty-three, the spindle motor suddenly stops or slows down during the working process of the engraving machine
1. The working voltage is unstable or overloaded, and a voltage regulator can be added; 2. Check if the middle line is connected well, and whether the line head has de-soldering.
Twenty-four, when the engraving machine sets the origin, sometimes the distance between the forward and the right is uncertain.
1. The limit switch fails. When the system returns to the system origin, the limit switch is closed and popped open. Change the limit switch; 2. The drive line is loose. Try to fix it tight.
Twenty-five, when the engraving machine starts resetting, the position of the X-axis, Y-axis, and Z-axis is indefinite.
1. The limit switch is broken (the limit switch is always closed), and can be replaced; 2. The drive line is broken (X-axis 14-pin and 15-pin short-circuit, Y-axis 13-pin and 15-pin short-circuit, Z-axis 31-pin and 15-pin Short circuit), change the drive line or separate the short circuit; 3, the drive board is broken, you can change the drive board.
