I feel like I've gone through every step, every manual, every forum, every post, and every mention of an Ender 3 Max Neo and cannot find the answers I am looking for. I recently shorted out the board for my Ender3 Max Neo and figured I could just replace the board. I attempted to use a Big Tree Tech board but it wouldn't communicate with my sonic pad so that one was no good. Then I got a 4.2.7 creality board and now I can't find the firmware for the printer. I am about ready to commit heinous war/hare crimes against this printer. All I want in this world is to get this printer working with my sonic pad. Please help.
