There’s an Epilog Mini (50w) at our local community college and I love using it…
However, there’s a lot of fussing with having to deal with it, ventilation being upper most, figuring out all the settings for what you want to do being another.
I think there are a few members here who have posted that they have smaller laser cutters and maybe they will chime in.
From the info I’ve read, I would highly recommend doing some Googling and Youtubing to see what’s involved. It’s probably more than you realize (maybe not, though). The small cheap Chinese ones apparently need cooling (think tubs of ice) and a lot of coding. The more expensive ones (has the Glowforge come on the market yet?) look easier to use.
You may want to see if there’s a Maker Space or Fab Lab in your area and see if they have one you can see / use.
The college mentioned above is opening a Maker Space in the next few months and will have a larger laser cutter (120w!).
Laser cutters are wonderful to create all sorts of things for creating jewelry! Good luck.
Edited to add: I’d also recommend listing what you want to do with it, and then seeing what you need. The lasers I mention above are CO2. They cut acrylic and such beautifully, but not metal. For that you’d need a fiber laser ($$$$). (At least for the metals I use; I don’t use aluminum so can’t speak to that.)
There’s also another thread somewhere here on Orchid that addresses a similar question. It’s not too old, so it might have the answers you’re looking for.
