M42 - Change pin status via G-code Use M42 Px Sy to set pin x to value y, when omitting Px the onboard led will be used.
M80 - Turn on Power Supply
M81 - Turn off Power Supply
M82 - Set E codes absolute (default)
M83 - Set E codes relative while in Absolute Coordinates (G90) mode
M84 - Disable steppers until next move, or use S to specify an inactivity timeout, after which the steppers will be disabled. S0 to disable the timeout.
M85 - Set inactivity shutdown timer with parameter S. To disable set zero (default)

M202 - Set max acceleration in units/s^2 for travel moves (M202 X1000 Y1000) Unused in Marlin!!
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
M207 - set retract length S[positive mm] F[feedrate mm/sec] Z[additional zlift/hop]
M208 - set recover=unretract length S[positive mm surplus to the M207 S*] F[feedrate mm/sec]
M209 - S 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 X Y
M220 S- set speed factor override percentage
M221 S- set extrude factor override percentage
M240 - Trigger a camera to take a photograph
M280 - Position an RC Servo P S, ommit S to report back current angle
M300 - Play beep sound S P
M301 - Set PID parameters P I and D
M302 - Allow cold extrudes
M303 - PID relay autotune S sets the target temperature. (default target temperature = 150C)
M304 - Set bed PID parameters P I and D
M400 - Finish all moves
M500 - stores parameters 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)
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.
