3.1.
Light Engine
Maintaining the NXE400 light engine is critical to get best printer performance.
There is a protective film on the top surface of the light engine. Keep it clean and free of
streaks. It may be cleaned with xClean, isopropyl alcohol, or glass cleaner. Don’
t use sharp
objects or abrasive materials to clean it. Keep the build plate clean of burrs and the resin
free of cured shards of resin. Detailed care and maintenance enstructions may be found
online.
The LCD is delecate and should be protected from damage.
Don’t drop objects on the light
engine top surface to avoid cracking the glass. Remove the build plate before turning off the
printer to avoid it falling on the light engine. Don’t apply pressure to the edges of the LCD to
avoid damage to the data conducters.
The light engine will become ineffective if dust is allowed to build up. Always keep a filter
installed and change 3-6 months depending on air quality.
After removing resin and membrane, run the cleaning job from the
System
screen to inspect
the light engine for damage (dead zones, contamination). Keep the door closed or use
protetive eyewear. It should look like this:

Resin System
The NXE400 membrane is separate from the vat. Never load resin in the printer if the
membrane and vat are not installed and the clamps are not secured. Failure to do so may
result in a resin leak. The o-ring face seal must be in place to ensure resin seal, and must be
replaced if damaged.
Warning, Spill Risk:
Never unlock the vat clamps with resin in the vat. Drain
resin prior to unlocking the vat.
Use the black tray provided when removing a build to prevent dripping resin on the printer.
If resin is dripped on the printer, clean it immediately with Isopropyl Alcohol or xClean.
