I figure the increased power getting to the etching process also helps increase throughput. I’m guessing that you only need a total amount of energy to do a unit of etching work, so with more power you can do more units of etching work per unit time.

I don’t mean to poo poo FreeCAD the way I say this, but the vast majority of those features listed are bog-standard cad suite features at least by modern standards.

I’d love to see a FOSS cad suite kill my personal dependency on proprietary solutions, but as best I’m aware the UX is still hugely lacking.

The LEDs don’t particularly (unless it’s a very powerful one), their power supply does though. LEDs run on DC voltage, so they need a converter from the AC line voltage to not die instantly
