Arc that starts tangent to the previous move. Only the end point is needed. Direction is worked out by the control.

Addresses
| Address | What it does |
|---|---|
X Y | End point of the arc |
How it works
Not modal. G08 can not be used for a full circle.
Example program
G90 G01 X2.75 F15.0 (STRAIGHT LINE)
G08 X3.5 Y2.25 (TANGENT ARC)
G08 X4.25 Y2.25 (ANOTHER TANGENT ARC)
G01 Y0 (LINE)
G08 X3.5 Y2.25 (TANGENT ARC)
G08 X4.25 Y2.25 (ANOTHER TANGENT ARC)
G01 Y0 (LINE)
Example is in inch. Check offsets and clearances first.
Watch out for
- The previous move sets the tangent. A wrong previous block gives a wrong arc.
- After the block the control returns to the previous G00 G01 G02 or G03 mode.
