After assembling my printer K8400, It works perfectly from SD Card but when i connect it via USB to the PC / Raspberry PI (Octoprint) is detected as serial COM but I cannot connect to it with repetier/octoprint or any other software. It tries to connect but returns “xxxxxxxxxx”
Issueing the ls command with the board connected I get a positive response ( there is a COM port ). With the board disconnected I get the normal no COM detected.
I´m assuming there’s some protocol error in the board.
Has anyone had some kind of this problem?
P.S. - This board was already flashed with the 1.4 - 2 head firmware.
Thanks in advance,
