Why there is this error

Yes, here are HAL, INI, custom_postgui.HAL, macro with tool-change (here I made just small changes) and G-code Iam running. Note, on the guide there is written that there should be deleted all G43 commands, when I eliminate them, I get error in opening that. It writes : Bad character '\314' used, I was not able to figure out what it means.  

Try adding a line ending after the last line in the custom_postgui.hal. All of the other lines end with CRLF but the last line has no line ending character. In Linux these would normally be LF (linux). Yours are CRLF (Windows) but it doens't seem to be complaining about that.

Did this help? Or des the problem still exist?

No it didnt help, its probably because I transfered the files with USB to my windows PC from where I uploaded them here. I will try once put them from original PC with testing setup.


(I also added and tried the milling program with added line to postgui, it didnt work) <-- I thought its about adding a line, actually I have to first find out what CRLF and LF means, I searched something but cannt figure out how do I know if its CRLF or LF. If the file was saved in Geany with mode: LF, then Iam expecting its LF?

Symlinks can not be copied to USB drives, unless the USB is formatted as EXT4 filesystem.
To copy config folders containing symlinks to USB, compress them first and copy the archive to USB.
