Self Sourced Voron Trident 350 - Yet Another India Build

[d4h]

Why build a 3D printer?
I started on the 3D printer build journey when I was trying to create some printed parts for a custom rack. It took me a few weeks to learn enough of Autodesk Fusion 360 to create the parts. When I tried to print the parts from an online service, the quote for cost of printing was enough to fund an entry level 3D printer. That set me thinking that maybe I should buy a 3D printer. To cut the story short, somewhere along my search for selecting a 3D printer, I pivoted to building an open source Voron Trident 350. My main motivation is learning something new.

Why VT350 and not a smaller size?
Because, my custom part is large enough to warrant a VT350.

Why self source and not use a kit?
I believe that the learning experience self sourcing provides is much richer than using a kit. It allows you to cherry pick printer components. It’s a little cheaper. I initially thought of doing a stock build as people have been advising. But, I realised that I would rather have some of the mods to start with rather than retrofitting them later. The guiding principle for making choices and picking some of the components was to use things that are slightly ahead in the technology curve.

Here goes my first post.

It has taken me around 2 months to get comfortable with the 3D printer terminologies, Voron Trident reference design, figure my way around the manufacturers and the vendors that can be used to source the VT350 components.

A big thanks goes to the post Self Sourced Voron Trident 300 Detailed Build Log India Edition by sanketss84. Given the fact that AliExpress cannot be used to source the parts in India, his post gave me confidence that self sourcing is indeed possible in India without it. His post gives a detailed source of all the parts from BOM. I did an independent search for all the parts, but have referred to it when I had trouble finding vendors for some of the parts. The discussions on Voron Design Forum has been very helpful in a lot of my decision making.

I just finished ordering the last of the parts. So the parts are slowing tricking in.

Voron Trident 350 Wiring
This is the wiring diagram for the build. This is my way of practicing the wiring virtually where I can afford to do mistakes. It consists of 3 sections.
(1) Tool Head section - build around BTT EBB 36 V1.2 (G0B1)
(2) MCU and SBC section - build using BTT Octopus Pro V1.1 (H723), Raspberry Pi 4B that I had lying around and BTT U2C V2.1 to connect the Extruder Breakout Board
(3) 220 V AC section - has the 24V PSU, 5V PSU, Heating Bed and SSR

Tool List:

This is the set of tools I've procured. I'm hoping that they'll see me through the finish line.

Cutters & Strippers
I've gone for one good quality traditional wire stripper with manually selected holes and the second one a low cost self adjusting wire stripper.

1. Manual Wire Stripper - Ideal T®-6 T®-Stripper Wire Stripper for 16-26 AWG stranded and 14-24 AWG solid [Goodwill]
2. Self Adjusting Wire Stripper - Multitec MT-02DX for 0.2-8mm² (24-16 AWG) wires, with cutter [Sunrom]
3. Flush Cut Type Wire Cutter - TriangleLab® Model Plier [TriangleLab]

Crimping Tools
VT350 build requires three gauges of wires; AWG18 (0.75 mm²): AC Power Wiring, AWG20 (0.5 mm²): DC Power Wiring and AWG24 (0.25 mm²): Stepper Motors, all other wiring. Micro-connector terrminal crimping tool should be able to handle AWG18, while the bigger terminal crimping tool that can handle AWG20-24.

1. Micro Connector Crimping Tool - IWISS IWS-2820M Mini Micro Open Barrel Crimping Tool works on AWG20-28 JAM, Molex, Tyco, JST Terminals and Connectors [dc3d]
2. Terminal Crimping Tool - KNIPEX - Crimping Pliers - 97 21 215 for 0.5—6.0mm² (20-10 AWG) terminals [Goodwill]
3. Ferrule Crimping - Truvic HSC8 6-4A AWG23-10 Wire Stripper Self Adjusting Crimping Plier Ratcheting Ferrule Crimper Tool [Amazon]

Screwdrivers and Hexdrivers
Primary type of screw used in the Voron reference design is the hex socket screw. Other types of screws are used in the third party components used such as the electronic boards etc. I went with two kinds of hex drivers or Allen key drivers; one full set of L shaped keys and the other three T handle drivers for the socket sizes used in the Voron build (M2, M3, M5).

1. Screwdriver small - Taparia 810 Screwdriver - 100mm length Reversible - Minus Plus - [Sunrom]
2. Screwdriver medium - Taparia 853 Screwdriver - 200mm length Reversible [Pre-existing]
3. Precision Screwdrivers - Novo 24 Pieces Precision Screwdriver Set [Amazon]
4. Hex Driver - Allen Keys [Omrook 2mm, 3mm, 5mm]
5. T-handle Hex Driver - Allen T–Handle Hex key Hard Metal [Omrook 1.5mm, 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm]

Soldering Tools
I have an existing analog temperature controlled soldering iron. I'm getting the tips required for installing the M3 threaded inserts.

1. Soldering Iron - Noel Analog Temperature Controlled Soldering Iron (60W) [Pre-existing]
2. Soldering Iron Tips - Tips For Installing Threaded Inserts (M2-M8) [dc3d]

Measuring Tools
Apart from the recommended measuing tools, I came across Chaoticlab CNC Right-angle Ruler for 2020 profiles which I thought might be a good luxury to have for ensuring square corners.

1. Vernier Caliper - Freemans FDC150 Digital Vernoer Caliper 150mm [Pre-existing]
2. Steel Ruler - Steel ruler 30cm, 60cm [Local stationary shop]
3. Engineer's Precision Square - GROZ Engineer’s Precision Square - Blade Length 75 mm [Amazon]
4. CNC Right-angle Ruler - Chaoticlab CNC Right-angle Ruler for 2020 profiles [biqu]

Heat Shrink Tube Tools
Another luxury I'm procuring is the tools for labelling the wires using label printed heat shrink tubes.

1. Heat Shrink Tube Labelling - Casio KL-HD1 EZ-Label-Printer [Pacific Computers] - I got misled by listed price that was minus the 18% GST. Anyway, I went ahead with it.
2. Hot Air Gun - Inditrust 2000 Watt professional heat gun hot air gun with dual temperature setting [Amazon]
