Step 4Do Test Cuts
Whenever cutting a new material on the laser cutter you need to do some test cuts. And that's quintuply true when dealing with something as variable as cake. I found that each cake cut slightly differently, and different types of cake cut drastically differently.
There are two main conflicting things that you want to achieve when cutting through the cake. You want to make sure that you cut all the way through, and you want to avoid burning the edges of the cake as much as possible. Cutting all the way through means lots of power, avoiding burning means less power.
The solution is to use numerous passes at high speed and low power. By cutting repeatedly you can slice off a little bit of cake with each cut and avoid burning the edges. You can't scale up this approach infintiely, but for these thin cakes it works reasonably well.
For my particular laser cutter and cake I found that these settings worked quite well:
12 passes
600 dots per inch
100% Speed
60% Power
