This is my third CNC router build. The first was a MDF design and the second was a Shapeoko. Did not really like either of those designs so I started my own. The goals I had for this build: keep the part count small, low cost, and sturdy design.
The frame is 2" x 2" tubing. I had a friend weld the frame together as he has much welding skills than I have. Used about 16' of tube in the frame. The footprint is 24" x 24".
The linear bearing all from China ordered on eBay.
Electronics and Motors ordered on Amazon.
I have the motors dialed in. Have not had much time with work and home tasks. I did engrave a Thomas Train image on plexiglass. Also have been busy designing my 3D printer.
