how to do automatic tool change in linuxcnc?

I was dealing with Mach 3 and I wanted to switch to Linuxcnc, but I have a problem, which is converting the tool changer from manual to automatic. In the Mach 3 program, a macro file is placed and the commands for the automatic tool changer are in it. The question is how can I do it in Linuxcnc.
can any one help me .

Probe_basic screen have a ATC installed.

this is my tool changer in linuxcnc when i want to change the tool , (m6 t2) e.x. i need the programme do it automatically with my tool       

can you explain how. pls

It might help if you post the mach3 macro so people can see what that does.
 

There are lots of ways to control a toolchanger. The carousel HAL component can help, but that only handles the position feedback and toolchanger rotation, it doesn't include any axis moves or clamp/unclamp operations.

The most flexible way to handle those aspects is with a G-code subroutine. G-code is a pretty clunky programming language, but it makes it easy to incorporate axis moves etc.

So, basically, you end up writing a routine in G-code to do the same as your Mach3 macro.

It is also possible to do it in Python, if you prefer.

Classicladder is another popular option, but it is hard to incorporate axis movements if using that approach.

this is my macro in mach3
how i can do it with g-code or python ?
