1.1.5 (4.2.7) board hot end temperature control



  • I installed the new quiet board (1.1.5-4.2.7 and says Ender 3 Pro) in my Ender 3 and it really is quiet. The problem I'm having is that the hot end temperature constantly swings 4-5 degrees above and below the set temperature and won't hold steady. Most of the time it won't start printing, just says "extruder heating", I have to fool it by preheating 20 degrees higher than the printing degrees then lowering the degrees after it auto homes when told to print. Amazon sent me a replacement board and it does the same thing.
