each daub to expose clean cotton to the surface, until the optic is free of visible
contamination. At that point, prepare a fresh swab and clean the surface with a gentle
zigzag motion across it. Avoid any hard "scrubbing" of the surface, especially while
there are visible particles on it, and try not to use repetitive circular motions. When
you are done, be careful to remove any cotton threads that may have snagged on the
mountings. Allow the optics to dry before you operate your engraver.
Cleaning the Bearings and X-Beam
The bearing system in the laser should be inspected and cleaned about once a week
depending on use. Use a soft cloth or cotton swab with some alcohol or similar mild
solvent to clean the X-axis beam. Try to wipe clean the inner part of the X-axis beam
where the bearings ride. The inside of the beam is accessible and should be kept
clean, but our experience shows that with proper exhaust ventilation it will stay very
clean by itself.
Cleaning the Exhaust
Make sure the exhaust blower you are using receives proper maintenance.
Periodically clean the exhaust blower and duct system to remove built-up debris. If
you detect odor while engraving, or if the smoke in the cabinet is visible in the area of
the lens carriage, inspect the exhaust system. Check for loose or broken pipe/hose
connections, or obstructions. The photos below show where to clean the duct work of
your machine. You should also occasionally check your exhaust blower and the duct
work that is connected to it.
