1	$-Code	Setting	Units	Setting Description
2	0	Step pulse time	microseconds	Sets time length per step. Minimum 3usec.
3	1	Step idle delay	milliseconds	Sets a short hold delay when stopping to let dynamics settle before disabling steppers. Value 255 keeps motors enabled with no delay.
4	2	Step pulse invert	mask	Inverts the step signal. Set axis bit to invert (00000ZYX).
5	3	Step direction invert	mask	Inverts the direction signal. Set axis bit to invert (00000ZYX).
6	4	Invert step enable pin	boolean	Inverts the stepper driver enable pin signal.
7	5	Invert limit pins	boolean	Inverts the all of the limit input pins.
8	6	Invert probe pin	boolean	Inverts the probe input pin signal.
9	10	Status report options	mask	Alters data included in status reports.
10	11	Junction deviation	millimeters	Sets how fast Grbl travels through consecutive motions. Lower value slows it down.
11	12	Arc tolerance	millimeters	Sets the G2 and G3 arc tracing accuracy based on radial error. Beware: A very small value may effect performance.
12	13	Report in inches	boolean	Enables inch units when returning any position and rate value that is not a settings value.
13	20	Soft limits enable	boolean	Enables soft limits checks within machine travel and sets alarm when exceeded. Requires homing.
14	21	Hard limits enable	boolean	Enables hard limits. Immediately halts motion and throws an alarm when switch is triggered.
15	22	Homing cycle enable	boolean	Enables homing cycle. Requires limit switches on all axes.
16	23	Homing direction invert	mask	Homing searches for a switch in the positive direction. Set axis bit (00000ZYX) to search in negative direction.
17	24	Homing locate feed rate	mm/min	Feed rate to slowly engage limit switch to determine its location accurately.
18	25	Homing search seek rate	mm/min	Seek rate to quickly find the limit switch before the slower locating phase.
19	26	Homing switch debounce delay	milliseconds	Sets a short delay between phases of homing cycle to let a switch debounce.
20	27	Homing switch pull-off distance	millimeters	Retract distance after triggering switch to disengage it. Homing will fail if switch isn't cleared.
21	30	Maximum spindle speed	RPM	Maximum spindle speed. Sets PWM to 100% duty cycle.
22	31	Minimum spindle speed	RPM	Minimum spindle speed. Sets PWM to 0.4% or lowest duty cycle.
23	32	Laser-mode enable	boolean	Enables laser mode. Consecutive G1/2/3 commands will not halt when spindle speed is changed.
24	100	X-axis travel resolution	step/mm	X-axis travel resolution in steps per millimeter.
25	101	Y-axis travel resolution	step/mm	Y-axis travel resolution in steps per millimeter.
26	102	Z-axis travel resolution	step/mm	Z-axis travel resolution in steps per millimeter.
27	110	X-axis maximum rate	mm/min	X-axis maximum rate. Used as G0 rapid rate.
28	111	Y-axis maximum rate	mm/min	Y-axis maximum rate. Used as G0 rapid rate.
29	112	Z-axis maximum rate	mm/min	Z-axis maximum rate. Used as G0 rapid rate.
30	120	X-axis acceleration	mm/sec^2	X-axis acceleration. Used for motion planning to not exceed motor torque and lose steps.
31	121	Y-axis acceleration	mm/sec^2	Y-axis acceleration. Used for motion planning to not exceed motor torque and lose steps.
32	122	Z-axis acceleration	mm/sec^2	Z-axis acceleration. Used for motion planning to not exceed motor torque and lose steps.
33	130	X-axis maximum travel	millimeters	Maximum X-axis travel distance from homing switch. Determines valid machine space for soft-limits and homing search distances.
34	131	Y-axis maximum travel	millimeters	Maximum Y-axis travel distance from homing switch. Determines valid machine space for soft-limits and homing search distances.
35	132	Z-axis maximum travel	millimeters	Maximum Z-axis travel distance from homing switch. Determines valid machine space for soft-limits and homing search distances.
