We try to read CNC program from a u-disk, but no matter .txt .cnc or .nc files, neither of them can be recognized by GSK980TB2 controller, we do exactly according to the user manual, and the U-disk can be found, just can't copy the program to the CNC, it says: the file could not be read.

The U-Disk could be not compatible, you could use another brand U-disk and try again.
