Hi anyone here have a Large formate 4x8 Min laser engraver? I am looking at them and would like some abvise on what to look for. What is Flying Optics? also what are some brands of open table style laser engravers. I have looked at several 2x4 size from Universal and a 3x4 from laser pro. I just don't think the small size is what I want I would like to be able to cut full 4x8 sheet material on it. thanks in advance for your response.
