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 support for LinuxCNC style (ABORT,<msg>) comment, requires expressions enabled. Terminates gcode program, outputs message and returns error 253.
Added PRM[<setting>] and PRM[<setting>,<bit>] functions to expressions, returns $-setting value or value of bit in integer type setting.
"hardened" flow control code, fixed bug in repeat...continue handling.
Changed signature of grbl.on_gcode_comment event, now returns status code.
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 $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.
