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.
Parking mode improvements.
Removed requirement for external encoder for spindle sync if stepper spindle is enabled.
Improved handling of $680 stepper enable delay.
Moved probe signal handling from drivers to the core, improved handling of probe disconnected signal.
NOTE: The changes above are quite large, please verify probe operation after installation.
Some minor bug fixes such as incorrect error code returned for unknown $-commands and temporary incorrect position reporting on in-flight G92 offset changes.
Moved inbuilt G65 macros to the core and added macro G65P5Q<n> for selecting probe.
Added probe id to real time report: |P:<n> will be reported on probe select when more than one probe is available.
Fix for WCO and Ov real time status report elements not beeing reported as they should in some circumstances.
Added HAL parameter for minimum step pulse length set by driver, used for validation of $0 setting.
Changed HAL API signature for outputting step pulses, optimized to allow drivers to only change direction outputs when there is an actual direction change.
Improved handling of overrides at end of program when all motion is buffered. Possible fix for issue #714.
Some optimizations to allow higher step rates.
Added setting $676 with flags to control soft reset actions. See the changelog for details.
Workaround for Microsoft C adding a non-standard reserved keyword...
Improved handling of stop realtime command (0x19) for faster motion halt without losing position.
Optimized RAM usage. Fixed regression related to losing current coordinate system and tool offset over a stop.
Added named parameters _probe_state and _toolsetter_state. Both return -1 if state is not available.
These may return incorrect values initially so use with care.
Added option to homing enable setting ($22) for per axis homing feedrates.
!! Backup and restore settings over an update is recommended since all settings will be reset to default. Any odometer data will also be lost.
Added experimental support of LinuxCNC style subroutines.
Available for gcode run from local filesystem such as on a SD card or in littlefs.
Improved handling of G92 when G92 offset is changed while motion is ongoing. Ref. issue #241.
Fix for issue #521, crash when running G65 macro on ESP32.
"Hardened" stream switching code, likely fix for discussion #456.
Added definitions for up to four additional digital aux I/O ports.
Added real time report of selected spindle in multi spindle configurations. Reported on changes only.
Removed limits override input invert config, for safety reasons it is always active low.
Added HAL entry points for second RGB channel, renamed first from hal.rgb to hal.rgb0.
Added option to setting $22 to force use of limit switches for homing when homing inputs are available in the driver/board combo.
Improved handling of aux I/O pins when claimed for core functions.
Added flag to $9 for disabling laser mode capability for primary PWM spindle. Allows leaving laser mode enabled when a secondary PWM spindle is available and this is used to control a laser.
Added some generic setting definitions for stepper drivers, currently used by the motors plugin.
Implemented handling of single block, block delete and optional stop disable control signal events.
Added help for $S (single block), $B (block delete) and $O (optional stop disable) commands.
Added optional HAL entry point for outputting WRGB values to lights such as neopixels.
Improved $-commands registration to make it easier to add help text.
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.
New/modified core entry points for soft limit checking.
More delta robot tuning, added setting warning in $DELTA output if some settings are inconsistent such as steps/rad, acceleration etc.
Fix for issue #361, HOME status is not reported or reported late when auto reporting is enabled with setting $481.
Some drivers will now only disable hard limits (if enabled) for axes that are homing, this includes max/min limit switches.
HAL entry points and core handlers/events has been added and some have changed signatures in order to better support kinematics implementations.
More work on delta kinematics: new and changed settings, some improved functionality. Still in progress.
Added spindle type property to HAL, "hardened" code.
Added new setting $346 for action to take after tool change: either return controlled point (tool tip) back to the same position as before the M6 command (default) or move spindle to Z home.
Added $384 setting for controlling G92 offset persistence.
Improved $help command output and handling.
Moved the optional tool table in non-volatile storage.
Added gcode parameter support and optional expression support.
added some crossbar pin definitions and limited $TPW retract to Z home.
Moved some common driver code to the core and update of current position on steps/mm changes.
