It’s not meant to be too negative, just to help you avoid breaking your device.
There is already some great info in a thread started by @sdj544 : Some info on cnc tool changes and combo cnc/laser projects
And thread milling in non metal material will be possible with the right toolheads. Estlcam has some nice features to make that possible : https://youtu.be/xO-GHEIIOQQ
And if you do a search on the forum and on YouTube, there are people who have already done some work on aluminium.
Overall, the results aren’t great and it will definitely impact the lifetime of your device.
But feel free to try and show us how it’s done.
But don’t say we didn’t warn you
