This is why you ALWAYS test K9 crystals before inner engraving.
I ordered 30 K9 crystals from Alibaba to use with my xTool F2 Ultra UV for inner engraving. The plan was to use them for settings tests and giveaways but once I ran the UV light test, the results were ugly.
In this video, I show:
How I test K9 crystals for UV compatibility
How many crystals failed vs passed
Why “looks clear” means nothing for UV
A crystal that passed UV but wouldn’t engrave at all
Why Alibaba’s 12-hour “acceptance window” is a trap
How to dial in settings without wasting entire crystals
Out of 30 crystals:
Several failed the UV test
Some passed UV but failed engraving
Quality was inconsistent even within the same order
I also share a better way to test and dial in your settings by engraving near the edges instead of wasting the center something I hadn’t seen anyone explain clearly before.
If you’re doing inner engraving on the xTool F2 Ultra UV, this video can save you:
Money
Time
Cracked or wasted crystals
👍 If this helped you avoid a bad buy, hit Like, comment “TEST FIRST”, and Subscribe I’m documenting everything as I go so others don’t have to learn the hard way.
