DIY CNC 3 Axis 2418 Engraver Machine PCB Milling Wood Carving Router Kit Arduino Grbl
LinkSprite DIY CNC 3 Axis 2418 Engraver Machine is similar with LinkSprite DIY CNC 3 Axis 1610 Engraver Machine , we have increased its working area.
LinkSprite DIY CNC 3 Axis 2418 Engraver Machine laser engraving machine is suit for make non- metal processing such as plastic , wood , acrylic , pvc, pcb, wood or the similar material , etc.And airframe adopt profiles + plastic ，small size, light weight , USB interface , open source GRBL control.
The repeat positioning accuracy is with in 0.1mm under no-load, usually is about 0.05mm. Laser is considered no-load. If you use graver, the precision is depending on the hardness of the material.
And the engraver machine couldn't carve 3 dimensional objects. The different hardness of the material, the different thickness of the carving, and the maximum carving thickness is 30mm. The kit includes xyz stepping motors. You don't need purchase any parts separately, it is enough for working.
Grbl is a no-compromise, high performance, low cost alternative to parallel-port-based motion control for CNC milling. It will run on a vanilla Arduino (Duemillanove/Uno) as long as it sports an Atmega 328.
The controller is written in highly optimized C utilizing every clever feature of the AVR-chips to achieve precise timing and asynchronous operation. It is able to maintain up to 30kHz of stable, jitter free control pulses.
It accepts standards-compliant g-code and has been tested with the output of several CAM tools with no problems. Arcs, circles and helical motion are fully supported, as well as, all other primary g-code commands. Macro functions, variables, and most canned cycles are not supported, but we think GUIs can do a much better job at translating them into straight g-code anyhow.
Grbl includes full acceleration management with look ahead. That means the controller will look up to 18 motions into the future and plan its velocities ahead to deliver smooth acceleration and jerk-free cornering.

How to get a 2418 CNC mill moving
The 2418 CNC Mill is a small machine for cutting/carving detailed shapes in plastic and wood.
I spent a few hours taking great care to assemble it so that everything was lined up and square (see assembly instructions in a previous post). And as I did my eagerness to see and hear it come alive grew. But after I powered it up and plugged in the USB cable I discovered I’d have to wait. It’s taken me just as long to figure out how to get it running, as it did to assemble!
A lot of the documentation I found is great, if you’ve done a computer science degree. Hopefully these notes can save others some time.
Workflow for making a milled part
Firstly, a note on a general workflow in relation to the 2418 Mill:
- Refine idea and general form, layout, scale using paper, pens, rough prototyping.
- Detailed design and 3D modelling using CAD software (eg Fusion 360).
- Generate tool paths for milling using CAM software (eg Fusion 360), and export G-Code file to send to the milling machine. Note that some 3D modelling software may only export STL files, in which case (for the 2418 mill at least) you need another step to convert STL to G-Code.
- Send g-code file to the milling machine using G-Code Sender software (eg ChiliPeppr).
- Show milled part to friends.
This post deals with how to setup to be able to do step 4.
- The 2418 CNC Mill I have came with a Woodpecker 3.0 Grbl (this is printed on the board) circuitboard that includes:
- an ATMega 328P micro-controller (the same that drives many Arduinos), and
- a CH340G chip (a USB to Serial converter, which is like an adaptor between different ways to send/receive data). This chip requires a driver that you may need to install on your computer.
- I’m using an iMac with High Sierra 10.13.4
Here’s a schematic that indicates the main components, and what I was trying to achieve.
- Web-based G-Code Sender: This is the user interface, that allows you to communicate with the micro-controller – to tell it how to move the motors and cut your part. Various interfaces are available that allow either visual, or direct coding in G-Code (a programming language). Some are web-based, and these require something called a ‘Serial Port JSON Server’ to be installed and running on your computer. The JSON Server lets websites communicate (ie send G-code) directly with the machine machine (via USB cable).
- Grbl is software that’s pre-loaded (in this case) on the micro-controller. It converts G-code instructions into motor movements that do the milling.
Installing the CH340G chip driver
If you don’t have this driver installed your computer won’t recognise/see the mill’s circuitboard, and you won’t be able to communicate with it. Steps to install:
- Download here www.wch.cn/download/CH341SER_MAC_ZIP.html
- Open CH34x_Install_V1.4.pkg and follow prompts to install and restart your computer.
- Important: During the installation you’ll get a security/privacy alert. You need to allow/accept.
- Important: Despite point 4 above I also needed to go into System Preferences/Security & Privacy, to the General tab, and ‘accept’ again.
Installing and Running Serial Port JSON Server
If using a web-based graphical user interface (GUI), such as ChiliPeppr, to send G-Code files to your mill, you need to run another little program, on your computer, in the background called a Serial Port JSON Server. This lets the web-based application communicate with the milling machine’s circuitboard (or an Arduino). Steps to get this working:
- Connect your computer to the mill using your usb cable.
- Download Serial Port JSON Server
- Unzip the file. I put the folder it contained (called serial-port-json-server-1.94_macosx in my case) in the Applications folder on my Mac.
- Open the Terminal application (find it in /Applications/Utilities folder on Mac. If you remember MSDOS, it’s a bit like that).
- In the Terminal window, change to the directory where you serial-port-json-server.exec file is. In my case I’d type “cd /Applications/serial-port-json-server-1.94_macosx/“
- Execute the JSON program by typing “./serial-port-json-server“. (Note you can execute directly from Finder but doing so didn’t run the program in the same way, and it didn’t work).
- You should see something like this (…usbserial…) in the Terminal window:
Let it run in the background while you continue.
Open your G-Code sender
Now open whatever application you want to use to send your G-Code file to the mill. There are plenty of applications available. Here’s an extensive list of G-Code senders. I’m going to try a web-based one called Chilipeppr.
With the computer and mill connected via USB cable, select the relevant serial port in your G-Code sender.
Lastly, make sure the baby is not asleep in the next room. The machine is pretty loud.
How to assemble a 2418 CNC mill
A CNC mill is a pretty handy tool for rapid prototyping, as well final production of parts. I was recently gifted (very generously!) a 2418 CNC Mill. Woohoo! It’s a small DIY machine for cutting/carving detailed shapes in plastic and wood.
It took a few hours to assemble. I found I needed to refer to several sets of instructions to put it together. So I’ve tried to make a more comprehensive, one-stop instruction set in this post.
Overall dimensions of the frame are 340 x 330 x 230mm – width x depth x height.
In the box
- Allen keys (supplied). I recommend a ball-end allen key, which makes it easier.
- Tape measure
- Metal file
- Paintbrush to brush off aluminium shavings left on some parts.
- Put on some good ‘flow’ tunes. My recommendation is Lost Shapes by Waveshaper.
- File the rough edges off the brackets.
- Assemble base.
- Assemble the vertical frame (‘portal frame’).
- Attach portal frame to base frame.
- Assemble the table.
- Install y-axis screw and motor.
- Install the oblique supports.
- Install Z/X axis.
Align the top support pedestals to be flush with the top of the portal frame (use a square). Tighten the grub screws on the top rod. Align the bottom pedestals to be 26mm from the top ones and tighten. Tighten grub screws on bottom rod. Check the ZX assembly slides smoothly from one end to the other. When it’s good tighten up all the bolts and check again.
Install the stepper and idler bearing, ensuring everything is aligned.
- Install the circuitboard, motor and wiring.
- That’s it!

Ooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooh The orgasm was incredible.
As usual, I arched, but even after it was over, I did not lower my aunt Lena's head, she even began to struggle. I let go of her, I was shaking with a nervous tremor. I was exhausted. - Well, you bastard.
