Laser cooling fan turns off prematurelyduring cutting

Hi, what is the firmware version? You can find it by tapping on Settings > About Machine on the touchscreen.
The latest firmware is v1.12.1, you may install this version to have a try if it is not the latest firmware on your printer. You can get it from the following link:Snapmaker 2.0 Firmware Updates and Downloads
Please share a video of the problem if possible. Thanks.
