Regarding time-lapse photography, the following things need to be noted.
We will modify the firmware in the future regarding the condition that a file needs to be printed with 60 layers or more to generate a time - lapse video, currently, layers below 60 will not be generated.
You can try our tests to see if this still happens with our test files.
When using the Orca slicing software, no time - lapse video will be generated. Currently, the G - code of Orca does not support time - lapse photography. We suggest that you use the Elegoo_Slicerslicing software for now. We will improve the firmware to address the time - lapse photography issue caused by the Orca slicing software later.

When initiating a print via the web, time - lapse photography is not selected by default. You need to click the time - lapse photography option to start the print. If not selected, no time - lapse video will be generated.
Currently, during printing, the time - lapse photography button is not disabled. Repeatedly clicking this button will result in no time - lapse video being generated.

There seems to be a bug at present. When starting a print without bed - leveling data, no time - lapse video will be generated. This will be fixed in the subsequent firmware.
