Screen won't turn on when Powering On With BL Touch
I just got the BL touch for my Ender 3 V2, and I have everything installed, including the firmware, But when I turn the printer on the screen stays black and nothing else happens. the BL touch clicks twice, like it should, but the screen stays on, but black. I tried different firmware, but nothing works. Do i need to reformat SD card, or what?
