Added P-word option to G38.x probe commands, use to temporarily switch the probe input when multiple probes are available.
Fixed PWM spindle ramping, did not hit the target RPM.
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 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.
Some minor bug fixes such as incorrect error code returned for unknown $-commands and temporary incorrect position reporting on in-flight G92 offset changes.
Changed signature of vfs.on_mount() event.
Added grbl.on_cycle_start() event, fired on cycle start signal asserted or on cycle start real time command received.
NOTE: this is a relatively large change and may have introduced bugs and/or unintended side-effects. Please report any issues!
Added setting $519 for binding spindle encoder to given spindle in multi spindle configurations.
Added machine readable spindle enumeration report, $SPINDLESH.
Increased default value for setting $398 (number of planner blocs) from 35 to 100 for faster laser engraving.
NOTE: the $398 setting value will not change on an upgrade!
NOTE: STM32F103 builds for the 128K flash variants does not have enough free RAM and will keep 35 as the default value.
Increased allowed number of decimal places from 3 to 5 for $10x stepper step/mm settings. Ref. ioSender issue 346.
Added setting $650 for filing system options. Ref. issue 397.
Currently the following bits are available (depending on the configuration):
0 - Auto mount SD card on startup (1).
1 - Do not add littlefs files when listing the root directory (2).
Added build option for lathe UVW mode.
When enabled UVW words can be used to command relative moves for XYZ without switching to relative mode with G91.
NOTE: This permanently sets lathe mode and disables the $32 mode setting.
There are signature changes to some spindle, ioports enumeration and VFS filing system mount functions.
Added events to allow plugin code to handle tool table data, possibly stored on a SD card.
