Important

This guide is a bit long (mainly due to visual guidance) but please read it thoroughly! Following the guide exactly will create a PCB that works. If you encounter errors along the way, please go back and retrace the steps in the guide. This method will always produce a working PCB, so long as you follow these steps.

Introduction

This guide is a shorter version for learning to create PCBs for your prototype using Fusion360 Eagle. The longer guide is linked below, and contains many more tips and alternatives than this guide. Additionally, the guide provides a lot of information about the steps and why we are doing them. ONLY use the longer guide, if you have the discipline to read it thoroughly! It is THE MOST important part of this entire guide, so please know your strengths! If you know you won’t be able to focus on a long guide or you simply just want to create a correct PCB without additional detail, please just use this shorter one.

Designing PCB & Programming CNC 3018 PRO

Having a PCB makes your project more reliable, durable, compact, and also makes for easier integration. This guide makes a simple circuit with the ATmega328P as the main MCU.

The guide consist of three overall steps, each with a smaller step of sets:

1. Designing circuit schematic & PCB
2. Manufacturing PCB (programming the toolpaths)
3. Milling your PCB with UGS and CNC 3018 PRO

Words of advice

• The software we will be using is quite buggy, so make sure to save your progress along the way
• Make sure your circuit works on a breadboard, before proceeding to PCBs
• Make your PCB in modules/segments. Breaking it down into smaller pieces makes it much easier to design and troubleshoot (remember the PCBs can be bridged together, so you do not need get your entire project onto one PCB)
• For boards with a microchip, add a set of three pinheaders for pins rx, tx, and reset. This will enable you to debug in the terminal, directly on the PCB
