How to Set Work Zero on a CNC vs a 3D Printer
Printers find their zero by homing to switches; CNC machines are told theirs by touch-off into offsets. Why the philosophies differ, and what transfers.

CNC Blueprint Reading and Programming: How They Connect
Blueprint reading and programming are two halves of one skill: the print states what the part must be, the program states how to make it. Reading drives writing.

Is G-Code Just an X Y Coordinate Graph? Almost, But No
The graph intuition is half right: G-code positions live on Cartesian axes. What the graph picture misses is time, force, state, and the third dimension.
