My first guess, maybe it was not right saved with the cnc ending, or so?  
(I opened with wordpad (editor) and hit strg+s, so no ending was messed off)  
I use win10, latest updates.  
Lets have another try, please change the ending to gcode and try your file again.

Then i tried both files and they worked (tansfered over wifi, tooled from the touchscreen), what version of Luban and firmware do you run?  
Firmware 1.10.1\_20200822  
Touchscreen V1.10.0  
Controller V3.2.2

Luban 3.9.0 [Snapmaker Luban Downloads and Updates](https://forum.snapmaker.com/t/snapmaker-luban-downloads-and-updates/4949/16)
