Hi, Sorry I am not clear. are you saying each toolhead needs firmware update ? I though if I update the touch screen firmware we are all set. lets say I updated touch screen and toolheads do not work. in this case how do I update each toolhead ? If I disconnect the rest and keep only one toolhead can touch screen be able to update the toolhead firmware ? in my case will be X,Y,Z, laser 10w.  
Is there any load instructions I can fallow?
