What form of art work do you start with? Can you post an example? What host application?

I'm assuming that is a picture of the finished burn. What did you start with? Do you use the same size wood slug every time. Where is 0,0? I usually do test burns on scrap cardboard. For large circles when doing multiple copies I make a fixture to align the wood or burn a circle slightly larger that the target in the waste board.

No, I don’t use the same size.  Here’s another one. Wish Benbox can ‘trace’ the picture itself with low light instead of ‘square’ so i can see where it’ll engrave

Please post an original file that you feed to benbox so we can look at margins etc.

There is a free trail version of T2Laser that you can install on most Windows machines. There is also a free trail version of BCL. T2 is geared towards engraving while BCL is geared towards cutting. Both have excellent support and tutorials.

The BCL tutorials cover calibrating you machine. Well worth the time.

I would suggest starting with cutting/etching simple shapes such as rectangles, circles & triangles. Burning a 20x20mm square written in gcode is an easy way to get a warm fuzzy feeling that the machine is properly configured. Neon colored cardstock is my favorite test medium as it is cheap and reacts to the laser at low power.
