While it shouldn’t happen often, sometimes the mirror below the resin tank needs to be cleaned. Dust, water spots, and other debris can get caught on the surface and cause issues with your prints.
Cleaning the mirror is simple but it is an extremely delicate surface. As with any of the delicate parts of MoonRay, always wear gloves while cleaning to avoid contamination and fingerprints.
Clear the Area
To begin, remove the build platform from your MoonRay to ensure that specks of resin don’t fall from the platform onto the exposed mirror. Then remove the resin tank. You will now be able to see the mirror.
Clean the Area
Check the mirror for spots. If you have difficulty seeing spots on the mirror, illuminate the area with a flashlight. Use a damp, soft cloth or compressed air to clean the surface of the mirror. If the mirror has any resin on it, use isopropyl alcohol >90% with a soft cloth to break it down. (To clean a Kickstarter Printer's mirror refer to Cleaning Your Kickstart Mirror)
After Cleaning with alcohol clean and wipe it down with water to be sure any streaks from the alcohol are removed as well.
Replace first the resin tank, then the build platform. Try your print again!
