// note: this project allows to define up to 11 GRBL set of commands (makros) that can be called from setup screen.
// Those are defined by the user on a sd card and loaded on request into the ESP32 flash memory system (SPIFFS)
// So, once uploaded, they can be called without SD card.
// To be recognise as command, file name must be like Cmd3_xxxxxxxx.yyyy where
//       Cmd _ is fixed text (take care to the case)
//       3 is a digit from 1 up to 9 or the letter "A" or "B"; it defines the position of the button
//       xxxxxxxx will be the name of the button; first char must be a letter; min 1, max 16 characters, no space
//       yyy is the file name extension; it will be discarded
// The files to be used for upload must be placed in the root directory of SD card.
// To upload one of them, use the "Mill" + "SD->GRBL" menus and then select the file.
// After reset, there will be a button named xxxxxxxxx in the "Setup" + "CMD" menu
// If you upload a file having the same button position(digit 1...9, A or B) as an existing button, the new file will replace the button name and content of the previous button. 
// to delete a button create and execute a file having a name like Cmd3_delete where 3 is the button position (digit 1...9, A or B) to delete.

// ************************************ Commands for change tools
// This suppose that we can use G28 and G30 and that milling use G54 WCS.
// The GRBL commands used by those buttons are defined here
// _SET_CHANGE_STRING : Set the current position as the position where the tool must be changed; 
//                      This is saved by GRBL so it remains after power off; G28 can be use to move directly to this position (! if homing has been done)
// _SET_PROBE_STRING : Set the current position as the position where probing must be performed; 
//                      This is saved by GRBL so it remains after power off; G30 can be use to move directly to this position (! if homing has been done)
//                      The idea is to put a micro switch at this position (so there is no need to use a clip)
// _CAL_STRING : = calibration ; to be execute only once for a given work piece (WCS); Set XYZ has to be set before running this command
//               Program will perform a Z probe in order to know the Z offset for current WCS; This offset is then saved. 
//               This offset will be saved in flash memory; so it will still be known after a reset.
// _GO_CHANGE_STRING : Go to the change tool position in order to change tool.
// _GO_PROBE_STRING : Perform a probe with new tool and then change offset based on the offset saved during calibration;
//
// To perform those task we define set of GRBL commands with some extensions:
// $G asks GRBL for the modal parameters (G21 = metric,G90 = absolute,...); ESP32 program save them in order to restore them later on
//        Values are displayed on Log screen
// $# ask GRBL for all offsets (G54,...G28, G92, ...); Values are displayed on Log screen
// %M restore 2 modal parameters (G20/G21 and G90/G91)
// %z ask the firmware to save the current Z Mpos;
// %Z replace %Z by the saved value %z; this occurs when the string is sent to GRBL.
// %X replace %X by the saved value of G30 X offset
// %Y replace %Y by the saved value of G30 Y offset
//                  wait that all commands are execute (G4P0.0\n), then ask for offset and modal parameters that are automatically saved( $#$G\n ),
//                  then stop spindle ( M5\n ), then move Z up for safety ( G53G21G90G00Z-2\n ) ,
//                  then go to Probe position ( G30 keeping Z-2\n ), then probe at high speed ( G38.2Z-100F50\n ),
//                  then change modal to relative and mm ( G21G91\n ), then move Z up 2mm ( G0Z2\n ) ,
//                  then probe again at low speed ( G38.2Z-3F10\n ) , then wait that command is executed ( G4P0.5\n ) ,
//                  then save the Z WCS position ( %z )in ESP32, then rise Z up ( G53G21G90G0Z-2\n ) ,
//                  then goto predefined change tool position ( G28\n ) and restore 2 modal parameters ( M\n )
