If you are talking about the fact that the CNC is inset from the table edge by quite a bit, that is because I originally built the “Little Red” CNC on a single sheet of plywood for testing and troubleshooting purposes.
The CNC will be expanded to a full size “Big Red” version shortly, so when I built the full size table top, I simply re-used the existing plywood, and it ended up that the rail was inset by about 15". It will be moved to the edge when I get my longer struts cut.
