Install question - found 5 heat sinks with 3D printer but no instructions on what to do

Do I need to stick them onto my 4 transistors? They are a bit too big for that. And if yes - why would I get 5 heat sinks; I see only 4 transistors? Thank you.

(Not sure if my category is correct)


  • No host problem.

    Guess you mean a board for printer. Stepper drivers need a heat sink and often the bed mosfet could also use one. The normal board chips normally do not need one, but you should better search for your board and see where they placed them there so you know to do it right.
