I recently got an anycubic kossel (pulley version.) I have built the whole thing, but the LCD screen doesn’t work. It has two rows of boxes, and the knob doesn’t do anything. I have tried resetting the circuit board,switching the wires, and turning the contrast knob, but nothing worked. I don’t know what to do about it. As anyone can understand, it is very frustrating. please help. Please contact me at chadtamburro@gmail.com. Thanks.
Is the LEDs in your control board glowing?
