// 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<seconds> 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<seconds>. To disable set zero (default)
// M92 - Set axis_steps_per_unit - same syntax as G92
// M114 - Output current position to serial port

// M190 - Wait for bed current temp to reach target temp.
// M200 - Set filament diameter
// M201 - Set max acceleration in units/s^2 for print moves (M201 X1000 Y1000)
// 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<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.

// M304 - Set bed PID parameters P I and D
// M400 - Finish all moves
// 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)
// 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]
