Changes to allow stepper spindle to use per degree settings, ref. issue 926.
Changes for improved line number reporting for subroutines and branching gcode.
Added support for G66.1 macro call.
Changed behaviour of G50 and G51 (and the G48 and G49 shortcuts) controlling feed rate and spindle RPM overrides.
Added support for G10L0, reload file based tool table.
Fixed buggy handling of G43 - apply tool offset from tool table.
Refactored the encoder HAL/API to make it more flexible and as a first step to support rigid tapping.
See the changelog for further details.
Added lightweight JSON serializer outputting directly to file.
Fix for event handler sometimes called too early. Ref. issue #818.
For developers: added optional device filing system that can redirect file read/write to serial streams.
Added core on_spindle_at_speed event. This must be verified with actual VFD spindles, I only have a simulator available.
Improved handling of "iterated" settings, can now be fully implemented by plugins.
Added '$709' setting for second PWM spindle when available - PWM options.
Added properties to PWM spindles to allow "overdriving" PWM output when _RPM controls spindle enable signal is enabled with '$9' or '$709'.
Optimized Modbus CRC calculation, may fix issue with a compiler generating different code compared to most others. Ref. issue #723.
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 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.
Fixes issues for programs containing extended M-codes using single meaning words (which they as a rule should not do).
Added core support for spindle encoder binding to spindles.
Added sorting of spindle report: enabled spindles are sorted first in order of spindle number, disabled by type then spindle id.
Changed realtime report to report spindle number instead of spindle id on changes in the |S: element.
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.
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.
