iocontrol - interacts with HAL or G-code in non-realtime
[EMCIO]
EMCIO = io
or
EMCIO = iov2
I/O control
handles I/O tasks like coolant, toolchange and E-stop. The
signals are turned on and off in non-realtime with G-code or
in the case of E-stop in HAL.
I/O Control V2 (iov2) adds more toolchager support for
communication with the toolchanger.
Whether io or iov2 is used can be chosen in the [EMCIO] section of the INI file.
