Hardware
Touchscreen
Touchscreen Shows "not responding"
The Touchscreen shows “the machine is not responding, would you like to reconnect”. This is likely to happen
pre- and mid-printing.
Possible Causes
• The Controller or the Power Module is malfunctioning.
• The Touchscreen cable is connected wrongly.
• The Touchscreen itself is malfunctioning.
Actions
1. Check if the status light at the back of the Controller is breathing regularly.
2. If it's not breathing, then the Controller or the Power Module is malfunctioning. Check if the voltage of the
Power Module is normal.
- Unplug the DC power cable from the Controller, and measure the voltage of the pins shown below.
• The voltage between Pin 4 and Pin 1 should be around 24V.
• The voltage between Pin 4 and Pin 3 should be around 3.3V.
If the voltage is normal, replace the Controller. If not, replace the Power Module.
Please contact us at [e-mail] with the voltage results for replacement.
3. If it breathes as expected, launch Snapmaker Luban and connect your computer with the machine using the
USB cable. If Luban has no problem connecting with and controlling the machine, then the Controller is fine.
The cause might be on the Touchscreen cable and see step 4.
4. Unplug the Touchscreen cable from the Controller, flip the cable connector 180°, and plug it back in. If this
doesn't solve the problem, then the Touchscreen cable might be broken.
Please contact us at [e-mail] for replacement.

Touchscreen Shows "Fabscreen has stopped"
Possible Causes
• The firmware is outdated.
• The G-code file is too large. This usually happens when you transfer the file from Snapmaker Luban to the
machine via Wi-Fi.
• The G-code file can't be parsed by the Touchscreen. This may happen if the G-code file is generated by
third-party software that Snapmaker isn't compatible with.
Actions
1. Download and install the latest version of the firmware.
2. Try a smaller G-code file.
3. Download the latest version of Snapmaker Luban, and try to generate the G-code file on Snapmaker Luban.
If the problem persists, please contact us at [e-mail] for further assistance.

Linear Module
Clunk Sound While the Y-axis Linear Modules are Moving
The Y-axis Linear Modules make a clunk sound when moving back and forth.
Possible Cause
• The travel distances of the two Y-axis Linear Modules are not matched.
Actions
You can follow the steps below or refer to this video.
1.Turn off the machine.
2. Disassemble the Heated Bed and Support Platform from the two Y-axis Linear Modules.
3. Move the sliders to the front end of the Y-axis Linear Modules by hand.
4. Place a piece of the Laser Engraving and Cutting Platform next to the two sliders.
5. Make sure there is no gap between the sliders and the Laser Platform.

6. Turn on the machine. On the Touchscreen, control the Y-axis Linear Modules to the other end.
7. Check if there is a gap between the sliders and the Laser Platform.
8. Swap one of the Y-axis Linear Modules with the X-axis one. Then run the same test.
9. Choose those two that have the closest travel distance as the Y-axis Linear Modules.
If the problem persists, please contact us at [e-mail] for further assistance.

Linear Module Won’t Move Anymore
The Linear Module won’t move suddenly.
Possible Causes
• The Linear Module is malfunctioning.
• The Controller port is malfunctioning.
• The Converter is broken.
Actions
1. Turn off the machine, and then manually push the slider of the Linear Module back and forth.
2. If it takes more effort than other Linear Modules, then the Linear Module is malfunctioning.
3. If the slider can be moved smoothly, then the Controller port or the Converter might be the problem. Please
contact us at [e-mail] for further assistance.
Linear Module Only Moves in One Direction
The Linear Module can only move in one direction.
Possible Cause
• The end-stop switch is stuck or broken.
