In the event of filament tangle, running out of filaments, adding the pause code "M0" or manual pause, the printer will record the printing process information. We can tap the Continue tab in the figure below to continue printing.
The default pause time limit of the machine is 24 hours. If it is too long, the machine will not be able to resume printing.
You can find the gcode_macro.cfg file in Fluidd interface to modify the limit time.
