CiA 402 Folder Missing

I still use only one servo drive, set the position scaling, the maximum velocity of the system and I am experimenting with the homing.
Now I follow you guide about absolute encoders. I uncommented the rows for homing in the .ini and .hal files and added the missing PDOs for homing the .xml file.
By the way in your .ini file you have a homing settings that are not commented and below them you have commented home settings that are said to be only for homing. But if I uncomment them there will be duplicated home settings. Therefore I commented the first batch with home settings and ran LinuxCNC but the missing pins error appeared.

It clearly states under point 6 that after switching to the battery encoder cable, a reference run must be performed again. After that, you can comment out the lines.
The internal CIA402homecomp should be used for this one-time reference run.

What do your configurations look like?
