New to CNC, built my own, now upgrading and learning

Hello folks,
I love creating the things that I have in my head. The latest skill that I'm trying to become competent at is CNC. I've come here to share my experiences and get advice. My CNC is all aluminum and works great for most wood, but I'm in the process of trying to upgrade it for milling, somewhat unsuccessfully. Ha! If you'd like to follow along as I learn, please visit my YouTube channel: https://youtu.be/2QTZa2Ge9A0
I'll be asking questions here and trying new things to share.
Cheers,
Tyler
