These blades are very expensive (~1500SEK each), and last a really long time if you use the right blade, mount them the right way around and do not feed with excessive force. | These blades are very expensive (~1500SEK each), and last a really long time if you use the right blade, mount them the right way around and do not feed with excessive force. | ||

=== <u>What You Can't Sense Can Still Hurt You</u> === | |||
Today, Kevin wanted to engrave some galvanized steel on the xTool F2 Ultra. He figured it would be fine. He couldn't smell anything, so how bad could it be? | |||
Pretty bad, it turns out. Galvanized steel has a zinc coating that releases zinc oxide fumes when heated. | |||
Zinc oxide fume fever is a real thing and gives you (and the people around you) flu-like symptoms that hits you hours after exposure, long after you've left the space. Your nose won't warn you in time, or at all. | |||
This is also a good moment to think about the IR laser on the F2 Ultra too. You can't see the beam, it's infrared. That doesn't mean it isn't there, and it doesn't mean it can't blind you or burn you instantly. Invisible is not the same as safe. The rule is simple: if you're not sure a material is safe to laser, check the material list on the wiki before you start. When in doubt, ask. Don't be like Kevin, your senses are not a substitute for knowing what you're working with. | |||
