When creating the GCode file in Simplify the last layers I created them with a very large plane that had never happened to me before.
By putting the GCode file generated from that piece and trying to enter the files on the board, I got the error. Using the M30 command and the file name was solved. (And luckily ...).
It allowed me to reconnect with the board (I have the wifi version) and enter the rest of the options, but once I tried to access the saved GCode files again, it was disconnected and the error came out again.
