Carefully insert both heating resistors into the pockets in the hot end as shown in Fig. 3-3.
You'll need to add a little more RTV to both ends of the resistor in order to fully fill the cavity
that the resistors sit in.
Don't be surprised if your application of RTV is not nearly as neat as shown above. These hot
end assembly photos were shot by Andy Oprisko, a SeeMeCNC employee. He's literally built
hundreds of hot ends and is very, very good at it.
