At think|haus we can cut 3mm acrylic very nicely at 1/3rd of full power
on our 40W laser and we've done 4.5 and 6mm too. I highly recommend air

and flaming on wood and cardboard and probably improves cuts on all
Our laser, coolant pump, ventilation, and computer all share a single
regular 15A 120V circuit, but that will obviously depend on your equipment.
