|
- 'S is interpeted as the configured value range: PWM (default), Percentage, or RPM. (See `CUTTER_POWER_UNIT`)'
|
|
- "[`M3`](/docs/gcode/M003.html) and [`M4`](/docs/gcode/M004.html) aren't needed with `LASER_POWER_INLINE` and `LASER_MOVE_POWER` enabled. Power is set directly in [`G1`](/docs/gcode/G000-G001.html)…[`G5`](/docs/gcode/G005.html)"
