Section 12: Engraving Machine Maintenance
156
After cleaning the bearings, clean off the table and the rest of the inside of the
machine. Spending just a few minutes a week will pay off in the long run with better
quality and performance.
Optics
About once a week, you will need to clean the optics (mirrors and lenses) of your
Legend. If smoke, resin, or other contaminants are allowed to accumulate too
heavily, they will reduce the available laser power and may cause damage. See the
diagram on the next page for the location of all the optics.
