Rostock MAX v2 Assembly Guide – 4thEd.
Take the short length of 1mm diameter PTFE tubing from the thermistor package and cut it in
half. Trim each half so it's about 1-1/4” long. Remove the thermistor from the paper protector (aka
The Post-It! Of Shielding) and slide the a PTFE tube on to each of the thermistor leads as shown below.
Using a pair of needle nosed
pliers, bend a 90 degree angle in the
thermistor and PTFE tubing as shown on
the right. Take special care to not
damage the thermistor head! It's made
of glass and is very delicate.
Take the nozzle off the Permatex Ultra Copper RTV tube and dip the end of the thermistor into
the RTV as shown below.
The thermistor should now be installed in the thermistor port on the flatted side of the hot end
as shown. Set it aside in a safe place to allow the RTV to cure.
