I used the interface provided by Linux CNC, and did not modify its INI file and Hal file.
This is my own ini and Hal files, but my own ini and Hal files can no longer jog after all axes return to zero, which makes me wonder. Is there a simpler solution? Thank you for your guidance

All homing related entries in the ini file need to be in the [JOINT_x] sections not in the [AXIS_x]-sections:

You have no hal connections for the switches. At least I don't see them.

Rerun the config and select at least home switches.

And what Aciera said....

Hello, I'm not sure how to connect the Hal connection with the switch you mentioned. How should I configure it? Can you teach me?
Thank you.

Hello, I tried your method, but it doesn't seem to solve my problem. Do you have a better solution? This problem has bothered me for a long time

There is no better solution. You need to connect the home switches in your hal file.

Rerun pncconf and select the home switches for your inputs and it will connect them in your hal.

Something like this

net both-home-x <= hm2_7i92.0.7i76.0.0.input-01 <== YOUR INPUT HERE

net both-home-x => joint.0.home-sw-in
net both-home-x => joint.0.neg-lim-sw-in
net both-home-x => joint.0.pos-lim-sw-in

I haven't tried the method you said. I don't know where to start. How should I establish a connection between Hal and home?
