This is a simple black and white, easy-to-do canvas and paint engraving. This is the same technique that would be applied to multiple layers and colors. You start with the lightest colors to the darkest, with black as your top layer. For the purposes of a tutorial on canvas art, I chose a black and white image, This image is from a trail came in the area of Texas where I live.
Choose your canvas.
Grab some Rustoleum X2 white
Spray one even coat of white, let dry.
Spray one even coat of black, let dry, do a second coat if needed, let dry.
The idea here is to go from lightest colors to darkest. If you want colors, you can add a color layer on top of the white, so on and so on till you get to the darkest layer, then coat with black.
While your paint is drying move onto editing your image.
Choose your image.
Load image into XCS editor
Measure your canvas width and height
Load canvas into M1 or whatever laser you're using, center the canvas at the top middle.
Click reload in XCS to show your canvas on the work space
NOW, you want to get your image to over run the edges of the canvas by just a a couple MM. This creates a whole canvas cover with no weird solid line edges where the image ends.
If your image isn't already inverted, click on invert, now your image should be a negative image. If you're starting with a color image, you need to make it black and white by bumping the slider on either end one or two steps, then invert.
you want the blacks to pop, with out loosing details. play around with the sliders, slide details all the way up and play around with the grey scale sliders. The blacks are where the laser will burn, the darker the blacks the deeper the laser will go, keep that in mind when doing multiple color layers.
Settings are not set in stone. I HIGHLY recommend sacrificing a canvas, with same layers, same paint and do a grid test using the grid test function under the Array setting. I personally crap a small piece of the image I want to do and use that for my grid test on my sacrifice canvas. If you choose to forgo this step, you could maybe try 40P, 200S, 140-180LPI(depends on DPI).
Once you're happy with your settings, send it to the laser and let it run.
If you feel like it didn't go deep enough, do not move the canvas, run it again at a much lower power.
When you're all done, add a hanger if needed.
