I have cut through 3mm baltic birch plywood, which is just shy of 1/8". I’ve done a dozen or so of these
My laser is not the Sienci unit. I bought it before Sienci released their unit. In speaking with Ikenna, I believe that the true power output of mine is very close to the Sienci.
I don’t cut much with mine. It’s much quicker to cut with the router. But, the boss likes the burnt edges on these so I use the laser.
