Hello,
I’m interested in buying a Snapmaker 2.0 and have one remaining question.
How small can you engrave something with the laser? Could you make a world map on the size of a one cent coin and it would still be readable with a magnified glass?
laser engraves a line of approximately 0.1mm in width when focused correctly. No you will not be able to engrave something as detailed as a labelled world map onto a one cent coin.
You could probably engrave low resolution text with a height of 0.5-1mm.

When I asked this question a while back on FB, someone had done calculations and figured out that the equivalent if it was an inkjet printer (what is a non-3d printer referred to as nowadays?) would be about 230 dpi, if I remember correctly.
It was close to that number (260?). Less than 300 for sure.

When using the dot or line options from a image input (feed Luban a png, ask it to make laser g-code) the max resolution it says it will do it 10 dots / mm. I’ve been testing that the last couple days and it works beautifully. I’m reducing dwell time on each dot to increase print speed. (If I can do 100% power for 1 ms instead of 25% power for 4 ms then that’s almost 4x the speed!)
However, when making a shape in Luban (a square for instance) you can apparently tell it to fill it with horizonal lines at 20 / mm. I haven’t tested this yet, but it’s interesting, if that tool-tip wasn’t a mere typo.
