supercurio Posted August 23, 2022 Share Posted August 23, 2022 My 3rd Sherman board, this time after a failure during a pull force test of the 2nd one. The second one was L21-20 revision, and the new one instead is L22-15. I'm guessing that this revision number has something to do with manufacturing date. Leaperkim started to add an identifier sticker, maybe in order to track the mainboard itself instead of the motor code only for warranty purposes. 2 1 Quote Link to comment Share on other sites More sharing options...
