// Call gcode file : "M32 P !filename#" and return to caller file after finishing (similar to #include).
// The '#' is necessary when calling from within sd files, as it stops buffer prereading

// 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 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/sec]

// M406 - Turn off Filament Sensor extrusion control
// M407 - Displays measured filament diameter
// M500 - Store parameters in EEPROM
// M501 - Read parameters from EEPROM (if you need reset them after you changed them temporarily).
// M502 - Revert 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). Use S0 to leave off headings.

/**
* G29: Detailed Z-Probe, probes the bed at 3 or more points.
* Will fail if the printer has not been homed with G28.
*
* Enhanced G29 Auto Bed Leveling Probe Routine
*
* Parameters With AUTO_BED_LEVELING_GRID:
*
* P Set the size of the grid that will be probed (P x P points).
* Example: "G29 P4"
*
* S Set the XY travel speed between probe points (in mm/min)
*
* V Set the verbose level (0-4). Example: "G29 V3"
*
* T Generate a Bed Topology Report. Example: "G29 P5 T" for a detailed report.
* This is useful for manual bed leveling and finding flaws in the bed (to
* assist with part placement).
*
* F Set the Front limit of the probing grid
* B Set the Back limit of the probing grid
* L Set the Left limit of the probing grid
* R Set the Right limit of the probing grid
*
* Global Parameters:
*
* E/e By default G29 engages / disengages the probe for each point.
* Include "E" to engage and disengage the probe just once.
* There's no extra effect if you have a fixed probe.
* Usage: "G29 E" or "G29 e"
*
