I J | Polar origin in the main plane |
How it works
Modal until a new G93 or a plane change.
Example program
G93 I2.0 J2.0 (POLAR ORIGIN AT X2 Y2)
G00 G90 R1.0 Q0 (RADIUS 1 AT 0 DEGREES)
G81 G99 Z0.1 I-0.5 F8.0 (DRILL)
Q90 (NEXT HOLE AT 90 DEGREES)

The full 6-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- Program G93 alone in its block.
- On 8060 and 8065 the polar origin is listed as G30, and G93 has another meaning.
