Hi,
I have an Enter 3 Pro which I just upgraded my motherboard from a 4.2.2 to 4.2.7 and now octoprint will not connect saying no serial.
I upgraded the firmware with the Ender3-v4.2.7-BLTouch-20260220.bin from link below using the SD Card but the serial is not working.
I am using a Raspberry Pi 4 with Octoprint which says “No Serial Port Found“
I have also tried compling my own but still the same outcome, does anyone know what i am doing wrong?
It was working with Octoprint and serial and the only thing that changed in the motherboard.
