Re: [CAD_CAM_EDM_DRO] Laser Project

I said this in another email but 200 watts is usually easily enough for home
grow stuff. It doesn't sound like much but that is 200 watts of pure IR
radiation, unlike the 1kW or whatever you put into an electric heater that
is convected away over square metres of air.
