So I have the 40W due to show up tomorrow, and wanted to dust off my laser skills (skillz?).
I Have had this boring old keychain in my pocket for a few weeks and had to make in mine. This is the leo laser, ~2.8W ish, [topic]https://www.v1engineering.com/the-2-8-watt-100-laser/[/topic] full power 50mm/min (.83mm/s). In the video the larger etch was done at 25mm/s so I doubled it and made the smaller one at 50mm/s no difference, I have no idea how fast I should have been going but I am fresh out of keychains to test on.
Diameter is about 27mm so these are pretty tiny lines.
Fun with lasers…
Fingers crossed for the big one tomorrow.
