Touchscreen Shows "not responding"
The Touchscreen shows the machine isn't responding, would you like to reconnect.This can happen pre- and
mid-printing.
Possible Causes
• The Controller is broken.
• The Touchscreencable is connected wrongly.
• The Touchscreenitself is broken.
Actions
1. Checkthe condition of the light at the backside of the Controller.Normally it should be breathing steadily.
- If it's not breathing, the Controller might have an issue.Replacing it might solve the problem.
- If it breathes slowly, launch SnapmakerLuban and connectyour computer withthe machineusing a USB
cable.If Luban has no problem connecting with and controlling the machine, then the Controller is fine.
2. If Luban can control the machine, then the Touchscreen cable might be the problem.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 might be the problem.Replacing itmight solve the problem.
Touchscreen Shows "Fabscreen has stopped"
Possible Causes
• There is abug in the firmware.
• G-code file is too large.This usually happens when youtransfer the file from Luban to the machine via Wi-Fi.
• G-code file can't be parsed by the Touchscreen.Thismay happen if the G-code file is generated by a
third-party software that Snapmakerisn't compatible with.
Actions
1. Update the firmware.For the latest version,
visithttps://forum.snapmaker.com/t/snapmaker-2-0-firmware-updates-and-downloads/5443/12.
2. Try a smaller G-code file.
3. Download the latest version of Snapmaker Luban fromhttps://luban.xyz/, and tryto generate the G-code file
on Snapmaker Luban.
