 *  G10 - retract filament according to settings of M207
 *  G11 - retract recover filament according to settings of M208
 *  G28 - Home all Axis
-*  G29 - Detailed Z-Probe, probes the bed at 3 points.  You must de at the home position for this to work correctly.
+*  G29 - Detailed Z-Probe, probes the bed at 3 points.  You must be at the home position for this to work correctly.
 *  G30 - Single Z Probe, probes bed at current XY location.
 *  G31 - Dock Z Probe sled (if enabled)
 *  G32 - Undock Z Probe sled (if enabled)
 *  M203 - Set maximum feedrate that your machine can sustain (M203 X200 Y200 Z300 E10000) in mm/sec
 *  M204 - Set default acceleration: S normal moves T filament only moves (M204 S3000 T7000) im mm/sec^2  also sets minimum segment time in ms (B20000) to prevent buffer underruns and M20 minimum feedrate
 *  M205 -  advanced settings:  minimum travel speed S=while printing T=travel only,  B=minimum segment time X= maximum xy jerk, Z=maximum Z jerk, E=maximum E jerk
-*  M206 - set additional homeing offset
+*  M206 - set additional homing offset
 *  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/min]
 *  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.
 *  M218 - set hotend offset (in mm): T<extruder_number> X<offset_on_X> Y<offset_on_Y>
-*  M220 S<factor in percent>- set speed factor override percentage
-*  M221 S<factor in percent>- set extrude factor override percentage
+*  M220 - S[factor in percent] - set speed factor override percentage
+*  M221 - S[factor in percent] - set extrude factor override percentage
 *  M240 - Trigger a camera to take a photograph
 *  M280 - Position an RC Servo P<index> S<angle/microseconds>, ommit S to report back current angle
-*  M300 - Play beepsound S<frequency Hz> P<duration ms>
+*  M300 - Play beep sound S<frequency Hz> P<duration ms>
 *  M301 - Set PID parameters P I and D
 *  M302 - Allow cold extrudes
 *  M303 - PID relay autotune S<temperature> sets the target temperature. (default target temperature = 150C)
 *  M304 - Set bed PID parameters P I and D
+*  M350 - Set microstepping mode.
+*  M351 - Toggle MS1 MS2 pins directly.
 *  M400 - Finish all moves
 *  M401 - Lower z-probe if present
 *  M402 - Raise z-probe if present
-*  M404 - N<dia in mm> Enter the nominal filament width (3mm, 1.75mm ) or will display nominal filament width without parameters
-*  M405 - Turn on Filament Sensor extrusion control.  Optional D<delay in cm> to set delay in centimeters between sensor and extruder

+*  M405 - Turn on Filament Sensor extrusion control.  Optional D[delay in cm] to set delay in centimeters between sensor and extruder
 *  M406 - Turn off Filament Sensor extrusion control
 *  M407 - Displays measured filament diameter
 *  M500 - stores paramters in EEPROM
 *  M501 - reads parameters from EEPROM (if you need reset them after you changed them temporarily).
 *  M502 - reverts to the default "factory settings".  You still need to store them in EEPROM afterwards if you want to.
-*  M503 - print the current settings (from memory not from eeprom)
+*  M503 - print the current settings (from memory not from EEPROM)
 *  M540 - Use S[0|1] to enable or disable the stop SD card print on endstop hit (requires ABORT_ON_ENDSTOP_HIT_FEATURE_ENABLED)
 *  M600 - Pause for filament change X[pos] Y[pos] Z[relative lift] E[initial retract] L[later retract distance for removal]
 *  M907 - Set digital trimpot motor current using axis codes.
 *  M908 - Control digital trimpot directly.
-*  M350 - Set microstepping mode.
-*  M351 - Toggle MS1 MS2 pins directly.
 *  M928 - Start SD logging (M928 filename.g) - ended by M29
 *  M999 - Restart after being stopped by error
