[title] Connect hotend fan for MK3(S)
[* 9] ***This step is for MK3(S) only, go to next step for MK2.5(S) or MK2(S).***
[* 9] Do not use the Noctua coming with your Prusa printer, it is not strong enough for the Hemera. As of today the E3D fan specs are unknown and so we recommend to use the fan that comes with your Hemera.
[* 9] Hemera comes in 12V or 24V version. The 24V version has a 24V hotend fan that needs to be used on MK3(S) Einsy Rambo. The 12V version has a 12V hotend fan that needs to be used on MK2(S) or MK2.5(S) Rambo Mini. Double check the voltage of the hotend fan on its sticker.
-[* 5] ***MK3 only:*** As the Hemera hotend fan works with 24V you will need to connect it differently. You can use jumper wire or prepare an adapter.
+[* 5] ***MK3 only:*** As the Hemera hotend fan works with 24V you will need to connect it differently (Prusa uses 5V fans). You can use jumper wires or build an adapter.
