Blue screen and D3 led on in the mainboard
So, I just buy my 1st printer Ender 3, and I do the stupidity to run a gcode of leveling bed just after assemble the Printer (before auto home). some motor starts to make a strange noise and a Panic and hit "factory reset". I panic again and turn off the power supply in the middle of the process.
At this point my screen becomes just blue.
My seller try to reset the firmware using and SD card no success.
She send me a new main board I replace and the problem keeps happening.
Try to make a firmware using and SD card again and nothing happens.
Both boards are V4.2.2, and when I turn on the D3 led on the board lights up.
