Welcome True BelieversCongratulations, you typed some worthwhile keywords into a search engine or had somebody recommend this great link. I'm going to assume you've got a working Printrbot Simple Metal and you are looking to upgrade your hotend and you smartly decided to pick the mostly highly regarded hotend on the market, the E3D v6.
Why?I decided to start this journey because I noticed my thermistor seems to change it's mind over time (20 degree difference depending on the day). Did you know the standard Ubis hotend has the thermistor held in place with teflon tape? That's not even real tape, there's nothing to keep it from moving around.

Pain PointsThe E3D v6 is a great replacement for the Ubis with 3 pain points.
- The hotend is too efficient. It's shorter than the Printrbot was designed for. You'll need an adapter.
- The Ubis hotend has some Molex connectors that don't match the raw ends of the E3D v6.
- The hotend, like all good modern hotends needs a fan to be running at all times.
- The firmware on your board will need to be updated.
- Printrbot Simple Metal (with USB cable)
- E3D v6 1.75mm Universal (I bought mine from Filastruder.com)
- A printed hotend adapter (see Step 1)
- A bunch of little bits and bobs for a Molex connection
