Hi ... I purchase a 20w NEJE brand on a site ..... as a software I use laser GRBL and lightburn .... For the first two or three days I managed to cut 3mm thick wood ... with three four steps ... Resuming the work later .., this was no longer able to cut, I state that I have not touched the fire and other parameters ... only manages to affect maybe 1 mm. Also cleaned the lens, but without success. ..some solution (..if it exists) .. thank you very much...sorry for bad translation ..i use google translate

It is possible your laser diode died. or your lens got smokey (since you already cleaned it, the first one is assumed). NEJE has 6 months warranty for their laser modules AFAIK, so your best bet is contact the seller for a replacement.
Also, before contacting the seller, make sure you ACCIDENTALLY did not change the laser power or engraving speed.
