@ Tweakie.

Balsa cuts nicely but as with most organic materials  it's density can vary widely from inch to inch, not much of a problem when you need to cut it but if you want to engrave a rib number on the part going all the way through can weaken  it.
A high power high speed cut gives you a nice almost polished edge, to slow and you get a bit of carbon. A lot of air assist helps with the cut and has the added effect of pushing the balsa onto the bed if it's a bit twisted.
It also leaves behind a nice sticky brown tar like residue, the best things for cleaning it off are cheap and nasty baby wipe from ASDA. ( also available from other supermarkets )

On a safety note don't leave the room if you're cutting balsa, if the air assist fails and the balsa catches light, it will smolder until your left with just ash and a room full of dense smoke. Or possible just a pile of ash and no room.

I fly ARTFs  and the park zone Bind and fly but they never feel as good as flying one you've stuck together yourself though !

Get it out the basement, build a plane. attract it to a couple of bits of wire, and the spin round on the same spot as fast as you can until you puke !
How much fun can a boy have ??   What ya waiting for dude  ;D


Q,  where did you get the laser?                                     A, The peoples republic of China.
Q, what is the thickest wood material it can cut?              A, depends on the wood, up to 1/2" balsa, after that it looks too messy, 1/8" bitch ply, probably 1/4" birch ply although i've not tried that yet.


The above is 1/8" ply.

the end result.

That looks really great bb, nice job and nice clean cuts.

Just one thing, I think you may need to look at the software you are using to create the toolpaths as it seems to be cutting a little too close to the edges in places. Perhaps using offsets may help.
