Extreme newbie - I'm just about to purchase a DIY CNC3018 Router/Engraver, as a side application it would be nice to be able to cut paper/card up to 250gsm. There are three off the shelf laser powers available with the CNC3018 500mW, 2.5W and 5.5W, are any adequate to cut the card? I presume that I would need to clear the smoke quickly to keep the cutting efficiency and accuracy good.

Thanks for any advice offered.
