COMMENTS

When engraving wood with a laser, a brown, maple syrup like residue will deposit on the surface

of the wood. This is normal and impossible to eliminate by POWER, SPEED, or PPI changes.

More residue will be present when engraving deeper and/or slower. This residue washes off

with water and a sponge. We recommend using a kitchen sponge with a nylon string mesh

wrapped around it. Dampen the sponge and wipe off the residue. A damp chamois cloth works

well also. Do not use paper towels or a regular sponge because these materials will get lodged

in the engraved area when wiping and are extremely difficult to remove. A method to avoid

cleanup is to mask the wood with transfer tape and peel off the tape after engraving. If desired,

after engraving and before peeling off the tape, spray paint can be applied to color fill the

engraved areas. After the paint dries, peel off the tape. If an intricate drawing has been

engraved and there are many small pieces of tape to remove, it may be easier to flood the

masking, after engraving, with water. This will loosen the tape and it can be easily removed by

rubbing it off by hand. In the vector cutting example, the wood was elevated from the table to let

smoke and heat escape from underneath. If elevating the wood, mask and/or dampen the

bottom side of the wood very lightly and the water acts as a heat sink to prevent the underside

from flaming and charring. Elevating the wood also helps to determine whether the laser has

passed completely through since the cut pieces will fall through to the table when cutting is

finished. If raising the wood, set up the drawing so that the inner pieces of the drawing are cut

first, otherwise pieces may fall through at the wrong time.
