// http://objects.reprap.org/wiki/Mendel_User_Manual:_RepRapGCodes
//Implemented Codes
//-------------------
// G0 -> G1
// G1 - Coordinated Movement X Y Z E
// G2 - CW ARC
// G3 - CCW ARC
// G4 - Dwell S<seconds> or P<milliseconds>
// G10 - retract filament according to settings of M207
// G11 - retract recover filament according to settings of M208
// G28 - Home all Axis
// G90 - Use Absolute Coordinates
// G91 - Use Relative Coordinates
// G92 - Set current position to cordinates given
//RepRap M Codes
// M0 - Unconditional stop - Wait for user to press a button on the LCD (Only if ULTRA_LCD is enabled)
// M1 - Same as M0
// M104 - Set extruder target temp
// M105 - Read current temp
// M106 - Fan on
// M107 - Fan off
// M109 - Wait for extruder current temp to reach target temp.
// M114 - Display current position
//Custom M Codes
// M17 - Enable/Power all stepper motors
// M18 - Disable all stepper motors; same as M84
// M20 - List SD card
// M21 - Init SD card
// M22 - Release SD card
// M23 - Select SD file (M23 filename.g)
// M24 - Start/resume SD print
// M25 - Pause SD print
// M26 - Set SD position in bytes (M26 S12345)
// M27 - Report SD print status
// M28 - Start SD write (M28 filename.g)
// M29 - Stop SD write
// M30 - Delete file from SD (M30 filename.g)
// M31 - Output time since last M109 or SD card start to serial
// M42 - Change pin status via gcode
// 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
// M115 - Capabilities string
// M117 - display message
// M119 - Output Endstop status to serial port
// M140 - Set bed target temp
// 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.
// 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
// 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
// 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)
// M999 - Restart after being stopped by error
//Stepper Movement Variables
