Before every print, be sure to review the pre-print checklist and confirm that Ember is ready to print. Failure to do this can damage your printer.
If resin ever drips or spills inside the printer, immediately use a paper towel moistened with isopropyl alcohol to wipe it up before it cures.
Never fill the resin tray above the maximum fill line on the tray. Overfilling the tray will cause resin to spill over the edge of the tray into the body of the printer, which can damage your printer.
