Voron 2.4 350 — Build Manual

Where things stand (1 Oct 2026): the Core One+ is running, all the ASA is on the shelf, and the Voron kit is in transit (late November to late December). From the Gen 2 kit, the heatbed expansion joints and nozzle wiper go in before the first plate; the GT1.5 belts install later, together with the INDX conversion this winter — the whole print run goes down on the current Gen 1 belts. Every plate prints before the Voron kit lands.

How to begin

Cartons open, bins labelled, every plate printed. I planned it this way. Naturally.

1. Now. Read slicer setup. Do the pre-kit steps of Ch 00: what the kit supplies, tools, consumables, the flat reference and the bins (Steps 00.8–00.11); the Voron manual's front matter, the measurement log and the Discord questions (Steps 00.23–00.32). Do Ch 00a — Mains safety. Print the bin labels.
2. Pre-B00 checks, on the current Gen 1 belts. Step B00.0 (the one-time slicer wizard), then the pre-B00 checks: a belt pluck check and a hot first-layer check on its own project file, about an hour. Then B00, Gate A and Gate B. Gate B's insert row is the insert practice (Steps 00.14–00.16): seven KADRICK inserts, set by the adult. Step 00.13 waits for kit day.
3. Then every plate, B01 → B10, in the manual index timeline order. Sort each plate into its bins as it comes off the bed.
4. The day the Voron cartons land. Ch 00 — Before you start from Step 00.1, then follow the manual index timeline rows 14–31 — Tonight packs this into sessions for you. It is not the Build tab's chapter order: the timeline interleaves chapters (Ch 12 before Ch 01, Ch 06b after Ch 13, and more). Nothing waits on a plate.

How to proceed, every session

Open Tonight: it starts where your ticks stop. Pick the 30, 60 or 90-minute plan, tap its first step, work to the Pause: line, tick each step done. Resume on any chapter overview jumps to your first unticked step.

Tick a chapter's steps and this shows the machine as it stands at the end of it.

This site consolidates the Voron 2.4 R2 Rev D+ 350 build into one Prusa-style manual. Five tabs across the top (behind ☰ on a phone), and the sidebar only ever shows the tab you are in: Build — the 16 assembly chapters, in build order; Print — slicer setup, the 11 batches of the ASA run plus B11 (bay ducting), and the plate plans, checklists and bin labels; Plan — the manual index, the Tonight planner, the print plan (batch order and dependencies) and the instruction survey (source docs and known deviations); Reference — troubleshooting and glossary.

Bench mode

Open https://alexlicohen.github.io/voron-24-350-build-manual/ on the iPad (or the LAN URL printed by scripts/serve.sh when editing offline). Share → Add to Home Screen for a full-screen, app-like view. Tap the ☼ button in the header to keep the screen awake while you work — it re-arms automatically if the tab is backgrounded, though on iPadOS 16.4–18.3 it only holds inside Safari itself, not once added to the Home Screen (18.4+ fixes this); turn up Auto-Lock as a fallback on older iPadOS.

One page per step. Every chapter has an overview page — time, sessions, and a thumbnail grid of its steps — and each step is its own page: the picture large, then Parts, Do, Check, and what you're looking at. Move with the big prev / next bar at the bottom, the ← → keys, or a swipe. Each step page has a done toggle; ticks are shared with the chapter overview grid and with the whole-chapter page (linked from every overview as "Read the whole chapter on one page"), and Resume on an overview jumps to your first unticked step. Progress is per-device, in the browser, offline.

Searching a bare step number (10.58) is faster than "Step 10.58"; step pages are indexed individually. Tonight turns every chapter's Time: and Pause: lines — and every print plate's start — into a 30/60/90-minute session planner in the index's timeline order, generated fresh on every build and re-planned on each device from the steps and plates ticked there, with a "Before the kit" plan first; each segment links straight to its first step page. Those same Pause: lines mark the stopping points — where a sub-assembly is safe to leave and what not to do before walking away. Every step ends with a Source: line pinning it to the exact manual page, LDO doc or print-plan section it came from. The print section (see print-ready checklists and bin labels) has print-ready Checkpoint checklists and a bin-labels sheet — one label per bin (a chapter, or a sub-assembly such as a Z-drive corner), each listing the parts it should hold, its chapter and steps, and a QR code to that chapter's step overview — plus a bin map; every plate diagram in the print chapters shows which bin each part goes to as it comes off the bed. Print them for the garage bench where a tablet doesn't survive.
