CNC Foam Cutters are capable ... a HobbyCC FoamPro kit that came with the 4 axis stepper motor control board and 4 NEMA 23 stepper motors. GMFC software is used to both generate the g-code and ...

[Perry] was interested in adding a 4th axis to his CNC machine, but not very excited ... it doesn’t require any additional electronics and the only software tweaks are a bit of G-code hacking.

Then the CAM software calculates the tool paths for the actual manufacturing process. CNC routers have a minimum of 3 axes: X, Y and Z, or a 3 dimensional tool travel path. Some have more which means ...
