Hello,

I have a trouble with the engraving. I use a VFT Compact (Satisloh) and i use a mechanical tool for engrave.
I have a trouble when i hardcoated the Cr39 (and only the Cr39 because with the organic 1.6 the result is good)
I have a dipping machine (SCL CD200) and I use a vanish 1.52 (for CR39 and 1.6)
So when I hardcoated cr39 , the result is bad. I have a vanish point in the engraving. I test different hardcoated thikness and different depth engraving.
It's strange because the 1.6 the result is good. The result is good with different thickness and depth.

Do you have a idea?

Thanks for all and I sorry for this text. My english is very bad
