G05.1 AI contour control on or off
Fanuc G-code · Mill
G05.1 Q1 turns on AI contour control, which looks ahead many blocks and slows smoothly at corners for high speed, high accuracy contouring. G05.1 Q0 turns it off. Common on 3D mold and CAM output.

Watch out for
- This is an option. Without it the control gives an alarm or ignores the block, depending on the model.
- Give G05.1 Q1 in its own block. Turn it off before canned cycles and tool changes if the builder says so.
- Corner speed and accuracy depend on many parameters set by the builder. Do not change them without the manual.
