NAME
iocontrol - interacts with HAL or G-code in non-realtime
SYNOPSIS
[EMCIO]
EMCIO = io
or
EMCIO = iov2
DESCRIPTION
I/O control handles I/O tasks like coolant, toolchange, E-stop and lube. 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.
