Part of an article called G28 G-Code - Reference Return. From my website: https://gcodetutor.com/fanuc-training...
The G-Code G28 is used to zero return the tool to its zero position via a reference point at rapid speed. A basic example of this line would look something like this:
G28 G91 X0 Y0 Z0;
If the machine is in Absolute (G90) bear in mind that the X, Y and Z dimensions will be taken from the working Datum. I find it much safer to switch to Incremental with G91 before this move so the tool moves from the last known tool position instead of the datum that we set on the part.
