Hi Joy, I'm in the process of going through all the diy cnc designs online right now, and stumbled upon yours. Received 60W CO2 Laser cutter/engraver from china a week ago, configured, and realized that there is no way it can replace the cnc. So I figured I'm going to use Laser to build my first CNC. And your plans look great. All the aluminum extrusions can be ordered at aliexpress and other stuff can be made from MDF (for starters) and then metal plates.
I was wondering if you have the DXF files.
What type of controller and motors are you planning on using?
Also, what's your estimated budget?
Do you have a list of all the parts required and maybe the URLs?

Sorry for a lot of questions, I've never built anything like this before and this is a learning experience from me.

And thanks for sharing. Eagerly waiting for your update.
