I have had the chance to use someone else’s laser recently, and will again soon. So far I’ve only used 1/8th inch clear acrylic. Next session I’m going to cut some solid dark blue acrylic, some quarter inch clear acrylic, and if I have time, some 1/8 and 1/4 mdf from fleetfarm.
The laser is an 80w co2, and the current owner of the machine just got it from a good friend recently, and hasn’t figured it all out yet. For the 1/8 clear acrylic we found that 18mm/sec speed at 90% power was perfect for cutting through.
But how would those other materials relate? Should i expect the same settings for the blue acrylic? Would i want to lower the power when cutting the wood? I know most machines are differrent and most mdf is differrent, but could anyone throw a few suggestions for starting point?
