As you did with the hot end thermistor, dip the end of the heated bed thermistor into some RTV
and insert it in the offset hole in the Onyx as shown below. Make sure you've got your thermistor
oriented as shown.
Fig 5C-6: Thermistor dipped in RTV.
Cover the end of the thermistor with Kapton tape as shown below. This will both protect the
thermistor and help you position the leads for the next step – soldering them in!
