BigTreeTech UPS 24V
Are you concerned that a power failure will ruin your 48 hour printing? Don't worry anymore, with this module your 3D printer will recognize this in time.
The printer can fully recover from the power failure and continue printing exactly where it left off.
When the module detects a power failure, it moves the nozzle in Z a little away from the print and saves the position. After the printer has power again, you can easily resume printing.
