Place the cutting pad under the engraved/cut object,

the working area.
Cutting Pad
The laser power of this machine is very high, if you need to cut wood and other flammable
materials with a power of more than 70%, please ensure someone is watching the machine in case
of the flammable materials catches fire.
A lot of smoke is generated in engraving or cutting wood and other
objects, be aware of cleaning the air guide hood and anti-skid cover,
since there may be a lot of dust accumulation on it, especially working
with more than 50% of the laser power.
Remove the shield if you could, or turn on the air assit while machine
working, all of which would significantly reduce dust accumulation.
