I have a 18"x18" logo that I will be engraving on 1/4 cast acrylic. I have a turnkey, basically a re badged rabbit laser 60 watt and have recently replaced the tube and it seems much more powerful than when new. This tube has a very nice round beam and the original that only lasted for 300 hrs of light on time had a beam that looked like an oblong letter "o". I have just one piece so I need to get it right the first time. What would be a good power, speed and dpi to set for the engraving? I dont want to use my old tube settings and be too powerful. Thanks for the help.
