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.
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 $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++
