I got crazy and decided I was going to put a direct drive, and a CR touch, on my old ender 3. And then I realized that the board that was in there couldn’t support that. So I replace the motherboard with a 4.2.7 board. Now I need to update the firmware and I’ve tried to firmware’s off their list and neither of them seem to do anything. I don’t want to just keep trying to flash firmware onto this without knowing what’s going on. Could somebody point me to the right firmware and where to download it thank you.
