A customer asked if I could do it, so I had to try at least.
So I tested 1/4" Beechwood the other day & managed to get through with 2 passes (1st try was a pain & I kinda messed it up but played around with the settings with what others have recommended in other posts for Red Oak & eventually got it right the next few tries - 140 speed & full power) I didn’t care to put masking tape since it’s just a test, so there was a lot of charring .
& I just finished testing the 1/2" one (slightly thicker actually) & I did 14 passes with the same settings & type of wood. I assumed I’d get it with 4 passes but anyway … Most of it got cut, only some areas where there were curves were harder for it to do so I guess - the straight lines were A LOT faster to get cut - 1 or 2 more passes I think would have gone all the way through for the whole shape, or adjusted speed, not sure what though. & the edges were not 100% what I wanted, again on the curvy side, but clean enough, just a little sanding would smooth it out more.
There were flames but not too much, & not in all the areas of the cut.
@caribis2 I initially put the piece on the crumb tray but felt it was waaay too close to the laser, so I removed it & put in jigs instead.
I haven’t engraved yet, I think that’ll be easier to figure out; I just wanted to get the test cut out of the way to know if it’ll actually work then I can engrave later on. I wouldn’t want to do this on a daily basis but at least now we know it works, so I’d say that was a success!
The back was not masked, the front is (clean underneath)
