Preparing the Hot End

For this task, you'll need the following components:
You'll also need the Permatex Copper RTV sealant as well as a few toothpicks.
The hot end for your Rostock MAX v2 3D printer uses Permatex Ultra Copper RTV to hold both the
heating resistors and the temperature sensor (the thermistor) in place. Because it takes 24 hours for the
RTV to set fully, it's a good idea to get that started now. The hot end will have to remain upright during
the period that the RTV is curing. The simplest way to do this is to use the large white box the Acrylic
parts are shipped in. Take the parts out of the box and using a pair of scissors, cut a "+" hole in the top
by shoving the scissor blade straight in. Put the Acrylic parts back in the box and set it aside – we'll use
it soon!
Before we start on this, I'd like tighten the nozzle that's installed in the hot end. Grip the hot
end by the heater block as shown below and gently tighten the nozzle with a 5/16" wrench.
Take care not to grip the sides of the heater
block too tightly – you don't want to damage it.
