Quick question for all the laser folks out there. I am finally starting to play around with the 45w laser on my 48x48. I am very new to this and tried some text and graphics today on a small maple plaque. As you can see, I am getting the overburn marks around everything I laser. I am trying to get a very dark etching so I was running the toolpath at 70% power and 90ipm with a 45 deg crosshatch pattern.
This is not deep burning and sands off easily, but I would like to know what the best practice is since I am just learning the process. Not sure if this is a speed/power issue or if I need to put down masking tape or Oramask to keep it from happening. On a side note, the first pass does not seem to burn so much but when it comes back for the cross hatch that’s where most of it seems to come from. Any suggestions would be appreciated. Thanks….Rick
These are the setting I went with. I did start out at about 30% power with some faster speeds but I was only getting the brown looking text and not the deeper black like I got when I slowed it down and increased the power. Not sure if there are other ways to get that rich black looking laser texts. Mayber faster speed but multiple passes? As for the air assist, and again sorry since I am new to the laser world, but is that doing this with the round knob on the top of the laser or do you mean from the controller box?
