Power Module Doesn't Work
The Power Module is unresponsive when the machine is turned on. The LED light won't flash, and the fan won't
turn.
Possible Causes
• The input voltage is out of range.
• The AC power cable is broken.
• The Power Module is malfunctioning.
Actions
1. Make sure the input voltage falls into the range between 88–264 V AC.
2. Use another AC power cable to test the module. The AC power cable is standards-compliant and
interchangeable. If the problem is solved, it means that the AC power cable is broken and needs to be replaced.
G-code File Wi-Fi Transfer Is Unsuccessful
The G-code file cannot be transferred to the machine from Snapmaker Luban via Wi-Fi.
Possible Causes
• The communication between the machine and Snapmaker Luban is interrupted.
• The Wi-Fi signal is unstable.
• The machine’s firmware or Snapmaker Luban is outdated.
• The G-code file is too large.
Actions
1. Restart the machine and Snapmaker Luban and reconnect them.
2. Check if the Touchscreen and your computer are connected to the same network. Make sure the Wi-Fi signal
is stable.
3. Download and install the latest version of the firmware.
Download and install the latest version of Snapmaker Luban.
If this doesn't solve the problem, try the next step. In the meantime, we would appreciate it if you file an issue
on our GitHub page. Your feedback will motivate us to do better.
4. Try a smaller G-code file that is less than 100 MB.
3. If the voltage and AC power cable are fine, then the Power Module itself is malfunctioning and needs to be
replaced. Please contact us at support@snapmaker.com for replacement.
