Speaking of “good ideas” – an observation…
Running out of flat surfaces to put machines on – and still wanting on occasion to use my low-power lasers to do engraving on ceramic tiles and such – I happened to think (in the middle of the night… as crazy ideas often do nowadays 
) to see if the Atezr laser’s large workspace (430mm x 430mm) might possibly double for my $79 Cenoz/Banggood 2.3W laser machine. Hey, no sweat! There’s plenty of room to install and remove the smaller machine…
Not only that, the enclosure’s exhaust fan and air assist are also available and can be operated separately… apart from the Atezr machine.
Not a real biggie, of course, but a surprisingly good idea for an old man to think of in the middle of the night (when not entertaining company, obviously!)…
