We used a 120-watt Legend 36EXT with the following settings: 100% speed, 10% power.
Keep these helpful tips in mind when performing this project:
Make sure your board will fit in your engraver - pay close attention to the dimensions of your bulletin board or you won't be able to engrave it because it won't fit!
Make sure to account for any framing during the design process. If your board has a one-inch frame around it, your engraving area becomes smaller.
Even using high speed and low power (100%/10%) cork engraves very well. Almost too well for graphics that are 100% black. We converted all of our artwork to various shades of gray (40 - 80 % black) to avoid scorching.
Insert your bulletin board in the engraving system. Open the file you'd like to engrave and make appropriate changes to text/design.
When you're done customizing the design, draw a vector box around it and send ONLY the vector job to the laser with the red dot pointer on. That way you can see exactly where your design will go. Adjust as necessary.
When you're happy with the placement of the design, remove the vector box and send the job to the laser for engraving.
