Cool.
If you have not done any CNC work before I highly recommend starting off learning with the wood CNC first just to wrap your head around concepts. There are a number of members who can teach you this.
Check out this talk thread for learning resources and how to progress
Doing this will likely save you some $'s on tooling. Next up get some training on the using the metal CNCs.
For this particular project keep in mind that feeds and speeds for brass are different than aluminum or mild steel. This just adds a bit more stuff to think about when creating your CAM. I can share the F360 settings I used from my project. Keep in mind that these were for the Taig CNC which we no longer have at VHS. You’ll likely be using the 6040 CNC for this project.
