Had an 'unwanted grid' showing up in both matte and annealed marks, independent of scan angle so I sent my 60W MOPA laser back to LasersOnly under warranty. The owner replaced several parts and said it was working perfectly and returned my laser. When I got it back it is having the exact same issue. The owner said it was settings related. I purchased another equivalent laser from Haotian and compared the exact same settings on the same piece of steel. The Haotian marks were perfect, the LasersOnly marks were terrible. The owner refuses to correct the problem. Google 'Haotian vs. LasersONly 60W MOPA' to watch on YT.Update 10/1 response to owner: "we were able to produce clean, angled engravings on his machine by slightly increasing the speed" * This is false. You are still claiming that it was a 'settings issue' even though it is clearly not (2 other people w/ same machine tested and had zero grid, and when I got a new laser it had zero grid - all running the same settings). Even the steel card you sent back at the end (with annealed marks) had grid marks in them (I have pics). You must not be detail oriented as you seem to overlook these things quite often."his machine continues to function correctly when operated with the correct parameters" * Absolutely FALSE. I have the machine sitting here for parts as I can't even sell it (other people see the problem in the marks no problem). All you have to do is watch the yt videos to see a comparison and that will tell you all you need to know. My new 60W Haotian laser DOES function flawlessly however (same settings) - which I highly recommend for anyone reading this review.
