Import BMP image to RDWorks (or other your laser program).
Wood fibers should be parallel to the long axis (X).
Image as well.
Rotate image 90 degrees if necessary.
Set parameters for engrave
• Parameters for 40 watt power laser (Program: RDCAM)
• Speed(mm/s): 300 Max
• Power(%): 20
• Interval(mm): 0.05
Material: solid birch, plywood birch
Speed and power must be chosen by experimentation.
Video
We use plywood birch in main.
It is accessible and cheap material.
Sand the plywood and cover it with varnish.
After engraving, wipe product with damp sponge to remove the soot and dust.

Jacob from United States
I am a beginner at CNC, I’ve never used a CNC machine before and with in a day I was carving. An awesome machine for a beginner to learn as hobbyists. I used the manual and the help video. One hour to assemble and test, very friendly and easy to use. It’s a good buy for the money. I would definitely recommend this machine to someone getting into CNCs.
