What You See

When this issue happens, you'll see a pop-up error message in XCS that says the Z-axis motor driver failed.

Why It Happens

1. The z-axis motor is overheated.
2. There is a connection cable issue between the main control board and the z-axis motor.
3. The laser driver board inside the laser module malfunctions.

How To Fix It

#1 Cool the Z-axis Motor Down

1. Power the machine off.
2. Open the lid to better cool the z-axis motor down for about 5 mins.
3. After about 5 minutes of cooling, turn on the machine and run XCS to check if this issue still persists.
4. It is advisable to avoid operating M1 in a high-temperature environment to mitigate z-axis motor overheating.
5. If this issue continues, move to the next step.

#2 Secure the Z-axis Motor Cable

• Check if the z-axis motor cable on the laser driver board inside the laser module (see the picture below) is loosely seated on the socket.
  • If so, reconnect the z-axis motor cable securely.
  • If this issue continues, proceed to the next step.

#3 Replace the Laser Driver Board

1. When the laser driver board inside the laser module malfunctions, the laser module cannot move in the up-and-down direction either.
2. If the steps above do not work and the problem still persists, this may be the cause.
3. Contact the xTool Customer Service for a replacement of the laser driver board to replace the malfunctioning one.
