Can anyone recommend a home CO2 or high-wattage diode laser cutter which can cut 3-4mm ply? We run an Epilog machine at my local makerspace, but I wonder if consumer machines have gotten reasonably good recently?
Basically any 50W Chinese laser should get you what you want. But at that price point you can't adjust the mirrors, no red dot to guide cuts, poor camera calibration etc. It's worlds away from what I expect you get with an Epilog.
Just keep in mind this is not a desktop machine to run in a flat. You need some infrastructure like a cooling loop and air exhaust, so this thing best lives in a basement or hobby room.
*Back to School special, since everyone has to get a new 50W machine each school year.
