Upgrading the Ender 3 Pro for Consistant Printing

Published: Jun 26, 2022 by Henry Forsyth

Getting Started

The web is riddled with suggestions and ideas for 3D printing, many of which sound like random howlings from random Reddit threads. This can make it challenging to determine what your machine needs, how to debug it, and how to get printing again. In this article, I’m going to lay out a buyer’s guide the upgrading the Ender 3 Pro. Each successive tier offers some added functionality. The tiers are organized by level of importance: tier 1 will include what I believe are the most important upgrades to make, whereas successive tiers are more for higher end user experience. In the end, though, I have spent a year working and vetting these upgrades to give us ground-truth data on the performance of these mods.

Note: as of 6-26-2022, this article is in-progress. It provides links to the resources you need, but offers little explination as to why the upgrade is helpful. More thorough explinations will follow shortly

Tier 0: The Machine

Reason: You have to have something to upgrade ;)

Ender 3 Pro

Tier 1: Upgrading the Mainboard

Reason: Quiets the machine and give you more headroom for the upgrades you can make

BigTreeTech BTT SKR v3.0

Tier 2: Minimal Hotend Upgrades

Reason: Resolves known issues with couplers/PTFE tubing that can causing jamming/filament issues

Capricorn Tubing and Couplers

Tier 3: Full Hotend/Extruder Upgrade

Reason: Increases the print speed while also improving overall part cooling

Upgraded Extruder

Upgraded Hotend

Tier 4: Uptimize the Build Surface

Reason: The stock print surface can wear out quickly, and the springs have too much play for quality printing

PEI

Spring Upgrade

Tier 4.5: Further Optimizing the Build Surface

Reason: So many people confuse "a level surface" with "level your 3D printer bed". In reality, the later just means that your hotend is a consistant distance from the bed. This upgrade helps compensate for any little issues you might have in that distance

Creality BLtouch

Tier 5: Adding More Debugging to your filament

Reason: Jams and issues seem (unfortunetly) commonplace with 3D printing. This acts as a nice sanity check to your issues. It can also detect when you run out of filament, so you aren't wasting it

Filament Runout Sensor

Tier 6: Octoprint

Reason: Gives you the ability to start prints remotely, and monitor them remotely. Also acts as a great source for debugging. Note, this optionn used to be cheaper before the chip shortage. 

Raspberry Pi

Fan

Cheap USB Webcam

Tier 7: Upgrade Fans

Reason: Makes your machine whisper quiet 

7025 Fan

4010 Fan

Power Bucks

Tier 8: Great tools to help fix your printer

Reason: 3D printers breaking isn't an 'if' question, its a 'when'. These will save you a lot of headache

8-in-1 Compact Ratcheting Multi-Bit Screwdriver

Socket Wrench Driver Adapter

7 mm socket for hotend
