Hello all. I’m completely new to building a mechanical keyboard. This is my first attempt, with the Tofu60 Redux Kit from KBDfans. It’s a hotswap PCB. My rookie mistake was probably that I didn’t test the board with tweezers before putting it all together. I started to test typing with it, but when I hit the “H” key, the entire column lights up and registers as “6YHN”. From what I’ve seen from people with similar issues, most people’s keyboards are older or have had something spilled on it. This is a brand new, out-of-the-box build, so what could it be?? Thanks.
