 ### Movement G and M Codes
 ```
-G0  -> G1
-G1  - Coordinated Movement X Y Z E
-G2  - CW ARC
-G3  - CCW ARC
-G4  - Dwell S[seconds] or P[milliseconds]
-G92 - Set current position to cordinates given
+G0   -> G1
+G1   - Coordinated Movement X Y Z E
+G2   - CW ARC
+G3   - CCW ARC
+G4   - Dwell S[seconds] or P[milliseconds]
+G92  - Set current position to cordinates given
 M0   - Wait for user, with optional prompt message (to press the LCD button, requires ULTRA_LCD)
        M0 Click When Ready ; show "Click When Ready" until the button is pressed.
 M1   - Same as M0
 ```
 ### Units and Measures G and M Codes
 ```
-G90 - Use Absolute Coordinates
-G91 - Use Relative Coordinates
+G90  - Use Absolute Coordinates
+G91  - Use Relative Coordinates
 M82  - Set E codes absolute (default)
 M83  - Set E codes relative while in Absolute Coordinates (G90) mode
 M92  - Set axis_steps_per_unit - same syntax as G92
 ```
 ### Firmware Retraction G and M Codes
 ```
-G10 - Retract filament according to settings of M207
-G11 - Retract recover filament according to settings of M208
+G10  - Retract filament according to settings of M207
+G11  - Retract recover filament according to settings of M208
 M207 - Set retract length S[positive mm] F[feedrate mm/min] Z[additional zlift/hop], stays in mm regardless of M200 setting
 M208 - Set recover=unretract length S[positive mm surplus to the M207 S*] F[feedrate mm/s]
 M209 - S<1=true/0=false> enable automatic retract detect if the slicer did not support G10/11: every normal extrude-only move will be classified as retract depending on the direction
 ```
 ### Z Probe G and M Codes
 ```
-G28 - Home all Axis
-G29 - Detailed Z-Probe, probes the bed at 3 or more points. The printer must be homed with G28 before G29.
-G30 - Single Z Probe, probes bed at current XY location.
-G31 - Dock Z Probe sled (if enabled)
-G32 - Undock Z Probe sled (if enabled)
+G28  - Home all Axis
+G29  - Detailed Z-Probe, probes the bed at 3 or more points. The printer must be homed with G28 before G29.
+G30  - Single Z Probe, probes bed at current XY location.
+G31  - Dock Z Probe sled (if enabled)
+G32  - Undock Z Probe sled (if enabled)
 M48  - Measure Z_Probe repeatability: P<points> X<xpos> Y<ypos> V<verbosity> E=engage L<legs of travel>
        As with G29, the E flag causes the probe to stow after each probe.
 M401 - Lower Z-probe (if present)
