So, I make stamping dies for our book bindery out of aluminum and and brass on a Shapeoko 4pro, with carbide create pro with no issue. I am purely a hobbyist and started this 3 years ago and knew NOTHING about CNCs. But, through lots of trial and error is this very doable. I use a variety of very small bits as small as .40mm (.0157") but these are SUPER fragile, so avoid that small if you can.
Personally, I run my machine very slowly (feeds) with a very small stepover (typically this is to because I am working with very small end mills). I will typically use the pre-built speeds and feeds for any end mill that I order from Crabide Create, otherwise you should also be able to locate and import the feeds and speeds tables from the manufacturer and load them into Carbide Create Pro too.
