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.
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.
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.
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.
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.
(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 clear of return value on CALL statement and added optional return value expression support to ENDSUB.
Improved handling of multiple simultaneous spindles. Still work in progress.
For developers: moved user M-code entry point hooks from the HAL structure to the core handlers and changed signature of the check() function to better support valueless words (letters) when parameter support is enabled. Removed deprecated parameter from the validate() call signature.
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.
Moved RGB API definitions to separate file and added some utilities for drivers and plugins. Fixed minor bug.
stream_open_instance(), signature change - added optional description string.
Allowed use of unused (by the core) axis words (ABCUVW) in M-code commands implemented by plugin code.
Added $PINSTATE command, for outputting auxillary pin states, modes and capabilities. Machine readable formatting.
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.
Now returns no data for alarm and error enums when firmware is compiled for 128K versions of the STM32F1xx MCU.
This frees up some flash space for plugins etc.
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 5s timeout/abort handling when waiting for index pulses prior to startiong spindle synchronized motion.
Added definitions for M401 (deploy probe) and M402 (stow probe) for plugin use.
Added support for probe protected message and alarm. Requires driver support for interrupt handled probe input.
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.
