G92 Coordinate system offset
LinuxCNC Tormach G-code · Mill and lathe
Shifts the coordinates so the current position reads as the given values. Applies on top of the active work system.
Format
G92 [X] [Y] [Z] [A] [B] [C]
Addresses
| Address | What it does |
|---|---|
X Y Z | Value the current position should read |
How it works
Modal offset. Stays until G92.1, G92.2 or a program end.
Example program
G20 G17 G40 G49 G54 G80 G90 G94 (INCH, SAFE START)
(TOOL IS OVER THE PART CORNER)
G92 X0 Y0 (CALL THIS POINT X0 Y0)
G0 X1 Y1
…
(TOOL IS OVER THE PART CORNER)
G92 X0 Y0 (CALL THIS POINT X0 Y0)

The full 5-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- By default the G92 offset is kept in parameters 5211 to 5219 and survives a restart. This surprises many users.
- Prefer G10 L20 or G54 to G59.3 for work offsets.
- G52 shares the same offset in LinuxCNC.
