G08.2 ASR reposition or buffer off
Hurco WinMax (NC) G-code · Mill
Ends ASR buffering, or on its own does a direct safe move. The tool retracts along its vector, reorients, then plunges to the target.
Format
G08.2 [X Y Z] [I J K or A B C] [L] [D] [H] [P] [R]
Addresses
| Address | What it does |
|---|---|
X Y Z | Target position |
I J K or A B C | Target tool vector or rotary positions, not both |
L | Safety clearance along the tool vector |
D | D0 linearization off, D1 on |
H | Z machine limit for the retract |
P | W axis limit for the retract |
R | Retract distance along the tool vector |
How it works
Ends G08.1 buffering. The direct form acts in its own block.
Example program

The full 6-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- If the tool cannot reach the L clearance the program stops with an error.
- Use H and R together to keep the Z retract short on big machines.
- G08.2 with X Y Z I J K before a hole cycle lets the cycle run along that tool vector.
