There is an issue in the software of the Anet A8 printer, that causes a break in printing, if there is a special character in the G-code; e.g. something like the German `ä`, `ö` and `ü` just let the Anet A8 stops working. 

This character can get into the G-code file through Ultimaker Cura, that insert comments like 

    ;MESH:Loki_hörner_v2.stl

into it.
