HEY everyone!

I have been looking at making one of these for a little while now, but have a quick question…

What sort of materials are able to be reliably milled. I have seen wood, acrylic and aluminium successfully done but how about Carbon fiber
or fibreglass, brass etc

Thanks in advance :slight_smile:

Those materials are pretty easy, CF just wears out bits a little faster than most and the dust is really bad for you, but no big deal to cut.
