Hello all. I am very new to 3d printing but have a background in cnc programming. My family was given an old ender 3 pro a while back and we used it for a while. Now that it seems it can no longer be upgraded to use a BL touch ( at least that is my understanding with its current firmware) my wife decided to go ahead and buy a new ender 3 V2. She tried to flash firmware and install a BL touch right out of the box and i think it caused us some issues. I really haven't taken the time to get into this thing but now it seems she flashed the wrong firmware to the system and now the display is wrong. it is setup for auto home and all that stuff. my question is this.... i want to reset everything back to the stock firmware and display so i am starting from scratch and then update everything to run on a BL touch after i have had the chance to verify the actual machine is setup and built properly. can someone guide me through how to get back to stock settings and display so i can do test prints without the BL touch installed? thanks in advance.
