I just purchased a Bigtreetech e3v3 with tft 35 screen and bigtreetech pi v1.2. I tried to understand all different videos on YouTube but get completely lost on how to do the whole setup to install it on my Ender 3 pro. I know I’ve read all the negative feedback on this printer but it’s my first one that paid $20 for. Any help please on how to install the firmware and being able to run clipper on it.
