The two outside switch connection are 1 common wiper center NO and the other outside- NC So when homing the transition is low to high.

I"m also asking the same question there are 3 pieces of the injection molded plastic, I assume these are for the travel arms somewhere. On a more serious note , a schematic showing the wiring for both for the AC supply and the 12VDC circuit for bed...I will be departing the build guide. to install a proper fused 3 pin AC connector used in the V4 edition. ALso am not a keen fan in replacing the duet board ,should it fry and will use a sSR to carry the load for the bed heater.. An index of the various steps with links to the departure point if this ”kit” had arrived from China, my comments would have been much more critical;. Good thing mine was the second last one , as far a s I know. Definitelly not for a Newbie

The washers in photos look like the metal ones, the plastic washers in the duet bag are transparent there are 4 each of them. and should be used to prevent possible shorts with the mount screws as noted in the duet documentation. NOT in the build instructions.

Does it matter?
Why can’t I edit my own comments after 5 min?
NOTE: If you purchased a machine after 8/22/2018 you will not need to install the 5A or 15A fuses. Your kit may not come with them, and will come with a blank side panel instead. The fuses are now built in to the Duet board. If this is the case, skip this step, we'll revisit this later in Step 50.
Seems my kit is pre- 8/22/18 and has the panel with 2 fuses and does not include a mains power fuse. I noticed that a version of the mains socket has mains fuses built in! Mine does not! Consider this a safety hazard
The Kapton tape is on the parts bag, looks like a yellow stripe.
are we relying on the fuse in power supply? I thought that the mains 110v should be fused before the rocker on off switch according to ul regs asb it enters the printer/device?

The fan with the KK pins goes under the Duet Board and plugs in to the fan connector on the board.
; there are a number of plated thru holes in a semi circle around the thermister as well as in the 12’o’clock position close to the + and - heavy supply traces in V10 edition of heater plate, anybody know the purpose of these? .This is more of a question?
to answer the one about bridging, there is a break between pads 1 & 2 trace so if you lift one due to overhating when soldering, you got a spare.
