? what do you have? what laser, what board, what software, what firmware.  most of the new lasers on the market do it stock out of the box with no modification needed. 
Laser: 2500mw A5 eleks maker

I have multiple issues! The kit is a BIQU 5.5 watt and I ought it through Amazon.  I can't determine the Firmware because there is no information on the board as to manufacturer, model or rev. I also can't get the Benbox application to generate G code. Any help will be appreciated.

It looks like a LaserAxe clone, but I can't tell if it's the later version which supports default Grbl pin outs or the earlier version but both firmware can be found in T2Laser.

Did they provide the original firmware? If it's benbox lx that would indicate it's standard.

The thumb drive has several folders. Unfortunately they are is n Japanese.  The only recognizable character are CH340 and benbox 3.7.99.

Well if it isn't working with what they supplied, you don't have much to lose.

Try T2Laser with the default firmware, let me know what happens (which motors move and in what directions, and if the laser works) then I will have a pretty good idea of what firmware you need. Worst case you could swap the board out.
