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).
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.
Changed $I NEWOPT "ATC" element to ATC=1 when ATC is online and ATC=0 when offline.
For macro based ATC code this is set to ATC=0 if tc.macro is not found and the new $675 flag is set.
Named system parameters _current_pocket and _selected_pocket updated to return the correct values.
Moved handling of keeping last tool number over reboot from template plugin to the core.
Added named system parameters _homed_state and _homed_axes.
Fix for failure to claim auxiliary ports in some configurations.
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 G30 as optional position for tool change.
Moved new tool change mode from PR#673 to $346 - Tool change options.
Moved Modbus RTU code from spindle plugin to the core.
Fixed bug in delayed task handler, might occasionally hang the controller.
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...
Fixed incorrect handling of G65 call parameters, axis words had offsets added. Ref. issue #594.
Refactored handling of multiple spindles. There are still some limitations but should work better now. Disabled override delays for now, needs investigation. Ref. issue #598.
NOTE: Please report any erratic behaviour after installing this version since it is a rather major change.
Added setting $358 to enable experimental functionality for fast rotary 'rewind' to stored G28 position.
Return move should complete in half a rotation or less.
For developers: added option to redirect debug via driver provided function when DEBUGOUT is set to -1 in config.h. Ref. issue #545.
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.
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.
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 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.
