Some low-level ioport improvements, added definition for virtual pins/ports.
Deprecated direct access to number of the different ioport ports in hal.port struct, use ioports_unclaimed() instead.
Removed IDLE state requirement for executing G65 macros, an error will no longer be returned and the macro will be run.
Added event handler for outputting welcome message on "native" USB connect for drivers that provides the linestate changed event.
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 code guards in order to free some memory for STM32F103 variants with 128K flash.
Changed Stop (0x19) real-time command behaviour, active tool offset and coordinate system will now be kept. Ref. issue #610.
Sub name matches filename with extension .macro.
Added core event for handling special gcode comments used by expressions and flow control: DEBUG, PRINT and ABORT.
Added overrideable default $-setting values for second PWM spindle to grbl/config.c.
(probe input pullup disable) settings from boolean to bitfield when driver support is available.
Added a few default values for settings in config.h, overridable from the compiler command line.
Added core support for per axis pulloff distance, needs plugin for configuring them.
Added HAL flags for disabling settings for MCU input pins pullup disable, may be set by
drivers/boards that has buffered (optocoupled) inputs that is not possible to change.
Added named parameters for getting absolute (G53) position: _abs_x, abs_y, ...
Available when expression support is enabled.
Changed stepper enable HAL signature to allow current reduction when idle.
Added reference id to spindle registration in order to allow configuring default spindle, and possibly additional spindles, at compile time.
Hide related settings when no spindle and/or coolant outputs are available. From PR #479.
Fixed typo related to Modbus direction signal. Ref. issue #478.
Fixed typo in handling of aux output port settings. Ref issue #476.
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.
The change is major and potentially dangerous, it may damage your probe, so please verify correct operation after installing.
Fix for STM32F4xx issue 161, Ethernet connection unresponsive if USB port not powered.
Enhanced ioPorts interface: New debounce option for input pins that are interrupt capable, currently only possible to enable via plugin code - later to be made available via a $-setting.
Added some wrapper functions for simpler plugin code++
Added simple task scheduler to the core, allows interrupt routines to dispatch jobs to the foreground process, delayed tasks and repeating tasks attached to the 1 ms system timer.
Some drivers and plugins now uses the scheduler for input pin debouncing, regular polling etc. The core uses it for stepper disabling and sleep monitoring.
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.
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.
NOTE: Delta and polar kinematics is WIP (work in progress) and incomplete.
Feedback is required as I do not have machines at hand for testing.
Ref. issue #341 and #346.
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 call to driver to immediately set stepper enable signals when $37 (Stepper deenergize) is changed.
Some minor improvements in settings handling and options reporting.
Added $384 setting for controlling G92 offset persistence.
Improved $help command output and handling.
Moved the optional tool table in non-volatile storage.
Added gcode parameter support and optional expression support.
Added `$ESG` and `$ESH` system commands for outputting current setting definitions.
Added setting descriptions to most settings. Work in progress.
Added/updated preprocessor code for leaner board map files++
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.
