new HAL entry point for querying/resetting driver status.
Added driver capability flags and settings, $742 - $745, for enabling and inverting motor warning and fault input signals (per axis).
Improved jerk acceleration. Ref. PR #660.
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.
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.
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.
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.
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.
Fix for unable to set $484 to 0, issue #466.
Added setting $673 for setting coolant on delay after feedhold. Available when safety door handling is not enabled.
Fixed obscure bug carried over from legacy Grbl related to this. Issue #467.
Enabled setting $394 for spindle on delay after feedhold. Available when safety door handling is not enabled.
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.
Fixed incorrect reporting of feed rate modes in $G response.
Added some ioPorts call wrappers, full support for reconfiguring output auxillary pins for PWM output.
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.
