WARNING: Make sure to protect the electronics against electrostatic discharge (ESD). Keep the Einsy board in the antistatic bag until it is needed for the assembly.
This section is challenging. There are a lot of little wires to deal with. I did find the instructions as-written were really good. Take time to study the pictures and go slowly when doing this section. My printer worked perfectly on the first try!
In previous chapters, I found the comments to be really helpful. In this one, they generally were not. I think this is because Prusa improved the documentation and/or the design since some of the older comments were made. For example, some comments say that you won't have any extra wire to leave slack -- that's not the case in Oct 2021. Plently of extra wire for all the connections.
I found this part even harder than the extruder assembly. The nylon thing and cable management stuff can call for better design and instruction improvement. For instance, first-time builder would under-estimate the effect of zip-tie orientation.... which can get in the way of extruder movement.
