+
+* Parts for a [Dragon Burner][] toolhead

+* Added a [Nevermore V4][] active carbon filter

+* Later on, I replaced the SKR Mini E3 V2 that came with the kit with the V3

+## Sensorless homing
+
+I was nervous setting up sensorless homing, fearing that without a physical switch the printer might decide to burn the motor against the edge or something. (I really have no idea how it works, hence my fear.)
+
+In the end it was straightforward.
+The [VORON 0 example firmware][] was already configured for sensorless homing and the only things I had to do was:
+
+1. Physically jump the `X-DIAG` and `Y-DIAG` pins on the board
+2. Tweak the `driver_SGTHRS` values (I landed on `85` down from `255`)
+
+And now I have sensorless homing working consistently.
+
+What confused me was that the [sensorless homing guide][] and the [homing macros][] it links to were slightly different from the [VORON 0 example firmware][] and it wasn't clear if I had to make all the changes or not.
 
 # Other setup things
 
+Even after building the printer and setting up Klipper there's still things left before the printer can print reliably;
+bed leveling, slicer configuration, and [print tuning][].
+It felt slightly overwhelming when I---a complete 3D printer beginner---went through these steps for the first time.
+
+I could still tune a lot more but with the standard SuperSlicer VORON 0 configuration and my existing filament settings the printer already gets pretty good results.

 # What's next?
 
 With a [VORON 0][] finally up and running I can now start working on some significant mods for my [Trident][trident]!
