Next, I should say that I'm not clear what the final product will be. You'll need to start looking at your image with a little different goal in mind, focusing on the edges that need to fit perfectly together.

And you may want to consider using layers, if it would help you keep things organized. There will be a good deal of duplicating and path operations.

So you have to remember to duplicate those pieces, because you'll need them for a different edge of whatever piece you're working on. The problem with your somewhat complex image, is that generally the path operations work with only 2 objects at a time, and often, 1 of those objects is sort of 'consumed' by the process. You are on the right tract with path operations (boolean). Unless I've misunderstood, I would continue to work in vector only. And changing the vector to raster, only to trace it back into vector again, seems like extra work. When I read your message, I did not get any indication that you were starting with a raster ('bitmap').

Is there a tool to slice every object and split them up according to their layering so each colour is divided out, or am I stuck with Booleans? I have poked around with the bolean operations, but I need to copy and paste every object back and forth which is slow to do. Making mistakes here will result in the laser cutter doing double cuts and making parts not fit. The issue is I could not perfectly recreate every edge on every piece as I could not line up one shape with another perfectly. Green/Red/Orange/Purple = Green/Red/Orange/Purple transp Some lines on the light blue will be cut at half power and then filled with black ink. The issue is I have done something a little more complex than normal (See Picture). It is simple: make a vector, the machine follows the line. I can engrave and cut acrylic, wood, leather, etc. I have used Inkscape with the G-code add ons for a laser cutter.
