Grbl includes full acceleration management with look ahead. That means the controller will look up to 18 motions into the future and plan its velocities ahead to deliver smooth acceleration and jerk-free cornering.

- Run-time command control: Feed hold (pause), Cycle start (resume), Reset (abort), Status reporting - Run-time command control: Feed hold (pause), Cycle start (resume), Reset (abort), Status reporting (current position and state).
- Controlled feed hold with deceleration to ensure no skipped steps and loss of location. - Controlled feed hold with deceleration to ensure no skipped steps and loss of location.
- After feed hold, cycle accelerations are re-planned and may be resumed. - After feed hold, cycle accelerations are re-planned and may be resumed.
- Advanced homing cycle with direction and speed configuration options. (Requires limit switches.) When enabled, homing is required before use to ensure safety. - Advanced homing cycle with direction and speed configuration options. (Requires limit switches.) When enabled, homing is required before use to ensure safety.
- Limit pins are held normal high with internal pull-up resistors. Wiring only requires a normally-open switch connected to ground. (For both ends of an axis, simply wire two in parallel into the same pin.) - Limit pins are held normal high with internal pull-up resistors. Wiring only requires a normally-open switch connected to ground. (For both ends of an axis, simply wire two in parallel into the same pin.)
- Hard limits option and plays nice with homing cycle, so switches can be used for both homing and hard limits. - Hard limits option and plays nice with homing cycle, so switches can be used for both homing and hard limits.
- New switch commands: Dry-run, block delete, single block mode, optional stop. A check g-code switch has also been added to allow users to error check their programs. This feature can also be used as a "program restart" by enabling the check g-code switch, begin streaming, and disable the check g-code switch at the desired point with minimal additional g-code. - A check g-code mode has also been added to allow users to error check their programs.
- Re-factored g-code parser with robust error-checking. - Re-factored g-code parser with robust error-checking.
- 6 work coordinate systems (G54-G59), offsets(G92), and machine coordinate system support. Work coordinate systems are stored in EEPROM and persistent. - 6 work coordinate systems (G54-G59), offsets(G92), and machine coordinate system support.

- G10 L2 and L20 work coordinate settings support. L2 sets one or more axes values. L20 sets the current machine position to the specified work origin. - G10 L2 and L20 work coordinate settings support. L2 sets one or more axes values. L20 sets the current machine position to the specified work origin.

*Important note for Atmega 168 users:* Going forward, support for Atmega 168 will be dropped due to its limited memory and speed. However, legacy Grbl v0.51 "in the branch called 'v0_51' is still available for use. *Important note for Atmega 168 users:* Going forward, support for Atmega 168 will be dropped due to its limited memory and speed.
