Intigued by recent thread about cutting square holes, I came to realise that it may be possible to join the 21 century and get the small cnc cutter from Aliexpress or such.
The thing is I'd like to cut not only plastics like plexiglass etc. but also metal, stainless steel in particular.
Machine doesn't need to be big, I think that 1' by 1' (30cm x 30cm for your metric afficionados), nor does have to be fast, I can wait

But it has to be able to cut through 20 to 18 gauge ss sheets (1 - 1.5mm), the sheets are designed for laser cutting as they're coated with special film, pic attached.
My guess is that 100W co2 laser may be too weak, but again have no experience in the matter.
Any input appreciated.
Thanks.
