CNC3018 Pro

Warning: This page is still a work in Progress, please contact Yichen Zhang (Spacezhang) on Slack if more Information is needed

Currently unable to finish the documentation due to lack of time caused by university stuff. Please contact me if you need a quick startup guide. Currently aiming for late august to complete the documentation

Warning: Beware of the dangers of CNC machines! Use at your own risk and only if you know what exactly you are doing!
Please contact Yichen for detailed explaination and tutorial

General Introduction

A small but full-featured cnc running GRBL donated to the lab for use, brought to you and maintained by Yichen.

Side View

What is the CNC 3018 Pro?

The CNC 3018 Pro is a generic engraving machine. This machine can be used to cut anything from wax to wood and is very good for getting started and learn how to use a CNC machine and how It works.

Acceptable work piece materials

Engrave/ Cut

• MDF / HDF
• Softwood, Hardwood, Plywood
• Acrylic
• PCB
• Very soft Aluminium (no harder than brass or aluminum 6061) (Detail untested)

+ Height Map support

Current Machine Location

The CNC 3018 Pro is currently on the right side shelf in the machine workshop.

Getting started

Basic operation

• Change Router bits
• Change Spindle
• Z Height map

Please Inspect the machine in regards of integrity before Use! Please check:
- Is all cable connected correctly and in tact?
- Is the linear rods and drive screw damage free?

[Detail and Tutorial comming soon]
