I tried with macros.
To try this, I configured my config like this
INI
[RS274NGC]
REMAP= M901 modalgroup=10 ngc=home_carousel
[HALUI]
MDI_COMMAND = M900 (it is for other thing)
MDI_COMMAND = M901
[TRAJ] NO_FORCE_HOMING = 1
NGC - home_carousel
hal
But no movement from my carousel when I press the home-all button. I presume that halui.home-all is not correct, what can I replace it with?

Does the 901 macro run from the MDI screen? (not calling it with hal signal)
If so, can you watch the pins and signals in halshow and see if they all do what you expect? That's the best way to diagnose this sort of thing.
I'd also run LCNC from the command prompt in a terminal and watch for an error when you run the 901 macro - either from MDI or via the halui.home-all button.
Basically trying to figure out if it's the macro or the hal connections.

my macro works straight away, calling it manually with the mdi works,
I looked to see if the home-carousel signal changes to high when I press home-all. the signal doesn't receive the information, so the problem is really with halui.home-all.
should i create joint_3 and set up HOME_SEQUENCE = 3 or there is a simpler solution for the homing sequence because joint.0.homed instead of halui.home-all allows the carousel to work, but at the detriment of an axis that does not perform the homing sequence.

Are you using an external button or a user-created screen button to trigger halui.home-all?
If you're just using a standard on-screen 'home-all' button or command then halui.home-all isn't getting triggered. The GUI is likely using it's own python command to trigger the home-all function.
Try connecting your halui.mdi macro to motion.is-all-homed. That should trigger the carousel to home after all joints are homed regardless of what initiates the home-all sequence.

thank you, it works perfectly. i have a question: isn't there a danger that MDI_command-01 will remain continuously high?

Using a oneshot between the motion.all-is-homed and the halui MDI command is the way to keep the is-homed from forcing the MID command high all the time. The same result can be had from classic ladder using a rising-edge coil.
Either way (HAL or ladder), you want a 'blip' to trigger the MDI command - like a momentary button instead of a on/off switch.
If you need help setting up the oneshot after reading the LCNC manual (in the components section), just ask.

Yes. If you look back in the thread I pasted a snip from one of my configs that has a 'one-shot' component in it.thank you, it works perfectly. i have a question: isn't there a danger that MDI_command-01 will remain continuously high?

everything is working correctly, thank you spumco for your help.
for anyone interested in the carousel home in the home-all sequence.
Ini:
home_carousel.ngc
hal
I'll see later if I need to reset the pulse
