Hi All, I've never attempted a project like this before but I would like to build my own CNC router. I would be using the table to cut mostly 18mm plywood and 5mm acrylic sheets. I can keep my designs to a 4x4 size so this size table as a minimum. My questions are what design should I decide upon for the above size, materials and ease of build due to being my first time? Where should I start?
