I was thinking of ideas to make on the CNC machine and looking on Google. I saw a really cool-looking marble maze and decided that's what I wanted to create. I liked the idea of putting handles on the sides, and I realized that they would make it a lot easier and more fun to play.
I started by using the pen tool to trace my image. I started with the maze and then added all of the circles on the outside to hold the acrylic. Making the gaps between my lines big enough for the marble to fit through was challenging. I had to use the white arrow tool to make some of my anchor points wider, but in the end, I got them all to be more than a half inch.
I uploaded my finished Adobe design as a dxf and imported it into Fusion360. Next, I made a stock that was 14 x 26 in and extruded it -1 in along with my maze. Then, I extruded my lip for the acrylic down 0.125 in. Afterward, I started to make my 2D contours and 2D pockets. When I was finished with that I simulated my cut, and it looked good so I was all ready.
I clicked on the post process in Fusion and downloaded my file. Next, I emailed my file to makerspace@dawsonschool.org. I put green tape on my wood and on the table and glued the wood down. Then, I set the x, y, and z coordinates on the CNC computer and began to cut.
A couple of things went well during this project, for example, my acrylic piece. I was able to design and laser print my acrylic in less than 5 minutes, and it was just very smooth. Also, the CNC cut went well because it didn't cut off as much of the side of the maze as I expected it to.Â
One challenge that I encountered was the 2D pockets and contours. I messed up one of the numbers in them, and it was throwing my whole project off, so I had to spend some time troubleshooting.
If I were to do this project again I would give myself more time to design it. I would make the maze an original design instead of just a classic maze, but I did not have enough time to do that for this project.
