I got the E3D Hemera (formerly called the Hermes) a week ago, and at first glance was impressed by the amount of documentation/guides E3D worked with popular YouTubers to create.

However, as time went on with my install, I discovered each guide was missing critical information, had bits of information incorrect, or included firmware files in a old or flattened format, making it difficult to discern firmware changes required.

I'm very familiar with Marlin 2.x, and so I finally decided to just go straight to the Hemera Datasheet, and finally got things working.

I'm not going to do a full guide, since I'm hoping one of the popular YouTubers who is capable of a high production quality video will do a comprehensive guide, but I have put together the following tips and lessons learned that should help some of you who are struggling but can't figure out why things aren't working.

*For reference: I have an Ender 3 with an SKR 1.3 using Marlin 2.x, equipped with TMC
