  1. now after some years, my screen need to be changed, I am afraid buying new display again I need the sofware or firmware upgrade which I dont have it anymore and I need it.

  2. I have in my mind at the same time to upgrade hot end and extruder, with sprite extruder plus CR touch , so i need a firmware that work for all above . any one can help ? or is this possible and i should stick to my original silent and touch screen without cr touch

i will be happy if anyone help thanks
