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 engraving machine is is currently stored in a EuroBox on the right side shelf in the machine workshop.

Getting started

Basic operation

  • Change Router bits

All Bits currently available. Collets are available in 1/2/3/3.5/4/5/6/7/8 mm.
Take out the two wrenches from the utility bag and use them to loosen the spindle and change the bits in the collet.

  • Change Spindle

Loosen the M5 Screw that holds the spindle motor in Place. Use a plying tool like the tip of a screwdriver to widen the gap and pull out the Spindle assembly.

  • Z Height map

Using software either directly downloaded from source or download from software section:
Connect the height probe in the cable tray to the Mainboard from the Machine.
Place and secure the workpiece to the bed of the cnc. Make sure the surface is metallic! The aluminium tape avaliable in lab could be used to create such surface.
Check that the router bit is secured in the spindle and move the head of the bits to a starting position relativ to the workpiece. Zero the machine via Zero XY and Zero Z on the upper right side of the software.
Enter the height map creation menu and set the desired size of probing area. Preloading the toolpath would be helpful as it would be visuallized.
Set the probing height, feed and speeds according to your need and the deviation of the surface height.
Connect one side of the probe to the metallic surface, and the other one to the router bit. You can test the connection with the spindle lifted and manually shorting the two connection while probing.
Click Probe and start probing. This could take a while but it will be worth it.
When Probing is finished, you can either save the heightmap or use the heightmag directly on the next engraving. Exit the height map creator and don't forget to click use heightmap.

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?
