I know that in a bitmap/png or general graphics file, I can use different grays (from white to black) to indicate depth for the engraving. However, I want to do this a bit more programmatically and would rather work with vectors since it seems to get better results when working with the glowforge.
Here’s the problem…
Let’s say I wanted to create a coaster where the the majority of the service has been cleared away and then I want three interlocking rings that have varied heights, where some of the rings are on top of the others.
What I can’t figure out in programs like Inkscape how to remove parts of the other objects such that they aren’t layered on top of one another. Obviously in the representation here, if the dark gray circle exists underneath the other circles then the laser cutter is going to engrave down to that depth, which I don’t really want.
Thus there must be a programmatic way or easy way to do this, that I’m just failing to see.
Bonus question is when I subtract out the “rings” from the black background disk, getting the exact alignment of the replacement rings on top also appears to be a little tricky to put the desired grayscale ones back on top.
Of course there’s probably another way to do this with doing multiple cuts/passes and if so would love to understand how to better setup a file to do that.
Any pointers or help would be great!
