we wanted to share, that we make a few tests for our 3.5W and 5.6W laser attachments
and good news are that you may engrave on painted aluminum with 3.5W diode laser
you may cut up to 8 mm of a plywood using 5.6W diode laser
and also our experement on engraving on stone was also successfull...
do not want to be spamy man...
you amy find more about it on (Endurance lasers) web site
or on youtube
George Fomitchev channel
hope that it is useful for many of you.
