---------------------------------------------------------------------- 5-axis version for GRBL Mega with RAMPS 1.4 Since the RAMPS board has 5 stepper driver slots, I added the management of the 2 unmanaged stepper driver slots in the original version of gnea/grbl-Mega. ---------------------------------------------------------------------- The number of axes is parameterized using the variable N_AXIS in the file grbl / nutbolts.h, the accepted values are 3, 4 or 5. Great care has been taken to maintain compatibility with the original version gnea / grbl-Mega: By setting N_AXIS to 3, we get the same executable as the original GRBL with same other options. This 5-axis version is currently limited to the use of the RAMP card. The 2 additional axes are the rotary axes A and B. ---------------------------------------------------------------------- TODO: (without order priority) - Make the same 5 axis functionalities for other hardware (DEFAULTS_GENERIC + CPU_MAP_2560_INITIAL), perhaps add 6th axis. :-) - Possibility to choice which axe are enabled for 4, 5 (or 6) : A, B or C rotational axis or U, V, W linears axis. - ?
Documentation md files typos corrections
- Add the possibility of renaming axis independently of their positions, - This add the possibility of moving axis without modification of the cpu_map.h file, - Cloning axis is also possible by using the same letter name for more than one axis.
- Renaming constantes and variables from *[XYZ]* to *AXIS[123]*
- Commentaire sur l'edition de config.h
- Update GRBL_VERSION & GRBL_VERSION_BUILD
Adding comment about the need to issue the $RST=* Grbl's command after changing the axis definition.

The machine works OK with Ramp 1.4 and Mega 2560
The machine does a hard stop when homing which requires an machine reset.
Switches are NC connected to X+, Y+ and Z+
Replaced Ramp 1.4 does the same thing
Mega 2560 is genuine Arduino board.
Is it possible that the board is damaged ?
Please help !
