G code and M code
G code: Address for preparatory commands:
G commands often tell the control what kind of motion is wanted (e.g., rapid
Positioning, linear feed, circular feed, fixed cycle) or what offset value to use.
M code: Miscellaneous function: Action code, auxiliary command; descriptions vary.
Many M-codes call for machine functions, which is why people often say that the "M"
stands for "machine", although it was not intended to.
