I finally got to use the CNC. It was super intimidating at first, but as I went through the tutorials it became a lot less scary and way more exciting. I started off with experimenting with just a very simple design, just to see how the CNC operates. With such a simple design, I still had difficulty in understanding how to fully control the CNC to do exactly what I wanted to do. So, I'd had to go back and forth between the CNC and the Mastercam about 10 times. There are a few things that if I knew how to control better, would save a lot more time - which is exciting to know. I see many possibilities in how i'll be able to really use this machine the way I want to.
