Added support for G66.1 macro call.
Changed behaviour of G50 and G51 (and the G48 and G49 shortcuts) controlling feed rate and spindle RPM overrides.
Added support for G10L0, reload file based tool table.
Fixed buggy handling of G43 - apply tool offset from tool table.
Refactored the encoder HAL/API to make it more flexible and as a first step to support rigid tapping.
See the changelog for further details.
Improved alarm handling, if a critical alarm is active when a non-critical alarm is raised the non-critical alarm will be delayed until after reset for the critical alarm.
Improved Modbus exception handling and added high level API call for creating and sending Modbus messages.
Added G65P7 inbuilt macro for interacting with Modbus devices from gcode. See the Wiki for details.
$700 controls whether they are scanned for internally in the main program (1) or always located externally (0).
If scanned for internally the program is run twice, initially in check mode to locate the subroutines before it is rewound and run in normal mode.
If stored externally the file P<macro number>.macro is run, <macro number> is the M98 P value.
Added experimental support for G66 (modal macro call) and G67 (end modal macro call).
Made axis letter to axis/motor assignment for axes ABCUVW freely changeable at compile time.
Fix for some G65 arguments being incorrectly validated for normal use (sign, range).
Added repeat support to G65 macro call via the optional L parameter word.
Changed default setting for ABC-axes to rotary.
Changed defaults for jerk settings to 10x acceleration settings.
Disabled jerk for jog, probe and spindle synchronized motion.
Added _active_probe system parameter, returns -1 if no probe inputs available.
Minor bug fix, G5.1 and G33.1 motion commands were not coverted to the correct string equivalent in $G output.
When X and Y coordinates are already at the tool length sensor (TLS)
position during tool change restore, Z was incorrectly not moving to
the home position after probing.
The issue was in the restore() function where Z movement was only
executed inside a conditional block that checked if XY needed to move.
This caused Z to remain at the probed position when starting from the
TLS XY location.
Fixed by decoupling Z home movement from XY position comparison,
ensuring Z always returns to home after probing (unless $346
disables full position restore).
Parking mode improvements.
Removed requirement for external encoder for spindle sync if stepper spindle is enabled.
Improved handling of $680 stepper enable delay.
Added tool name, pocket number and some lathe specific data fields to the $# tool output when available from the tool table.
If name is available it will be output as a push message on M6 if there is no message in the same block.
Added support for directory up, .., to VFS.
Added new option to $650 - File systems options to enable hierarchical listing of files and directories via $F and $F+ commands.
Added ADC/DAC resolution to $pinstate command, changed reported values to integer for ADC/DAC devices and float formatted for PWM devices.
Numeric settings can now be set via G65P1Q<n>S<value>, <n> is the setting number, <value> is the new value.
Changed alarm code for Modbus exceptions (communication errors) from 14 to 19.
Refactored MPG stream code to allow plugins to hook into MPG streams (via event handler).
Added _free memory system parameter, returns value in KBytes or -1 if not available from driver.
Changed basic stream data type from char to uint8_t, added HAL function and core API for releasing/closing UART streams.
