G500 Cancel settable work offset
Siemens 840D 828D G-code · Mill and lathe
Turns off G54 to G599. The G500 line is used instead, which is normally all zero, so the program runs in the basic coordinate system.
Format
G500
How it works
Modal, G group 8 (settable work offset).
Example program
G500 ; NO SETTABLE OFFSET
G0 X0 Y0 ; BASIC COORDINATE ZERO
G54 ; BACK TO PART ZERO
G0 X0 Y0 ; BASIC COORDINATE ZERO
G54 ; BACK TO PART ZERO
Example is in inch. Check offsets and clearances first.
Watch out for
- If values are stored in the G500 line they are active with G500. Keep it zero unless the shop uses it on purpose.
- G500 is often the reset default. A program without G54 may then run near machine zero.
