Hello all! Newbie user here, cutting on some 1/4 in birch plywood from Lowe’s. I know others have discussed challenges they’ve had with this product - but, for better or worse, this is what I’m stuck with cutting for the moment.
I’m making a bunch of memorial ornaments for my aunt’s funeral this weekend. They have largely come out surprisingly great! However (like others have reported), sometimes my cut doesn’t go all the way through. Unfortunately, I don’t figure it out until I have moved the surface, so I can’t easily re-cut without some jittering of the line. So - I’m trying to decide whether it’s better to have it cut with two passes, or whether I should just slow down the cut speed to reduce this issue. I previously had it cut twice (by accident) and it seemed pretty… High energy, with a lot of charring on the bottom suggesting the laser was bouncing around or heating up the crumb tray. So - I’m worried about fire, either way. What do you think is the safest choice?
My current cut settings (basic): full power, speed 140, focus height 0.25 and 1 pass. (this is plenty sufficient for virtually all of the cuts - just a couple areas have been problematic, but that damaged the product.) Thanks friends!
