This was the first foray for my kids and I into the world of CNC routers. I based this largely on the ‘OX’ design put out by Mark Carew of the OpenBuilds community. As you can see it uses the typical V-Slot ‘roller bearing’ arrangement which is promoted through OpenBuilds. So, while I did not buy all the components together specifically as a “kit”, I did go through the BOM (Bill of Materials) of the Ox and several other projects to accumulate a list of necessary components.
Here is a link to the Build Log with lots more photos and description.
