I | Text angle in degrees |
J | Text height |
E | Plunge feed rate |
F | Engraving feed rate |

The full 5-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- Text must be in parentheses after the codes on the same line.
- Use a small Z depth and a sharp engraving tool. Check part flatness first.
On lathes: Text engraving
Engraves a line of text, a serial number or the date with one block using a live tool. On a lathe it works in the G17 or G19 plane, not G18.
Verify on your machine. This entry could not be fully checked against the maker manual. Check your machine manual before you run it.

The full 7-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- Settings 29 and 73 must be off for G47.
- Engraving along an arc is not supported.
- A G187 E.002 before G47 keeps the letters sharp. Command G187 alone after to restore.
