Need some info

I've been wanting to see about getting some sort of low power laser rig to cut foam board, but I have no idea where to start. Yes, I am ready for the "try the search button" comments sure to follow, and I did look through the 2 pages of threads listed here.

I know the requirements I want for the set up.

1. Must work with Mac OS. I only have Mac, and I refuse to run bootcamp. I lost this first because it is the biggest issue for me.

2. I want to be able to cut a full sized sheet of foamboard, 20" x 30".

Any advice you guys can give in advance would be of great help.

MAC is a limiting factor. I run Fusion on mine to run WIN stuff including CAD and it's a beast of a machine. That would be the sticky wicket.

You can do many of the Chinese made tables and select your laser power from there. If it's just for foam, even at sea level you can probably get away with a fairly low power laser. Are you doing production stuff or hobby / intermittent use. If it's the latter and you are mechanically inclined, I would build a CNC type frame, possibly with a manual Z axis for the laser. If you want something more turnkey, then you likely will spend a fair bit of money on a machine big enough for that.

If you go the DIY route, have a look at alucobond panels for the enclosure. I built one for a friend a few years ago using this method (cnc frame, laser cutter, alucobond enclosure) that has been serving him well.

I suspect you may need to spend decent money on a machine. The table size is your problem.

Cheaper lasers have a 12"x24" or similar platform. To get larger usually means a much higher cost.
