My 30 watt fiber laser came with a counterfeit BJJCZ board. Sometimes it would play nice, sometimes it would not. (No Dongle, or...worse...be engraving then draw a straight line at full power back and fourth then keep going).
I decided i needed a new board that was genuine. Bottom line, I could never trust it.

I ordered a new board. My counterfeit board came with the extra axis so I got one with the extra axis.

I ordred a FBLI-B-LV4A

Problem is that my software says no dongle!

But....this software, on this post #20 worked:

I have put it through it's paces and I have not seen any of the bad behaviors. (Except the Rotary.. I haven't tried that.)

That said.. I would love to know more about this card and what software I should be running. It just says LITE for the version number.
