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.
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.
Improved handling of stop realtime command (0x19) for faster motion halt without losing position.
Optimized RAM usage. Fixed regression related to losing current coordinate system and tool offset over a stop.
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.
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.
