Sorry for the lame question but having a hard time to get a full understanding of hardware that I should buy,
What laser kit/setup would you get that works great with laserweb that can engrave on Metal 316L as low as 0.1mm? I can only see recommendation on controller firmware on github.
I am looking for the most stable one out of the four bellow, both from a software but also physical. Any experience on something that is implemented in a heavy used environment?
