G30 Go to stored position 2
LinuxCNC Tormach G-code · Mill and lathe
Rapids to the position stored by G30.1. Often used as a tool change spot. Axis words give an intermediate point.
Format
G30 [X] [Y] [Z] [A] [B] [C]
Addresses
| Address | What it does |
|---|---|
X Y Z | Optional intermediate point, in the active offsets |
How it works
Non modal.
Example program
G20 G17 G40 G49 G54 G80 G90 G94 (INCH, SAFE START)
G91 G30 Z0 (Z UP TO TOOL CHANGE HEIGHT)
G90
G30 (TO TOOL CHANGE POSITION)
…
G91 G30 Z0 (Z UP TO TOOL CHANGE HEIGHT)
G90
G30 (TO TOOL CHANGE POSITION)
…
The full 5-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- With TOOL_CHANGE_AT_G30 set to 1 in the INI file, M6 moves to this position first.
- Same trap as G28. Use G91 G30 Z0 to go straight up.
