Introduction: Let's Make a Simple Wood Engraved Design Using G-codes and M-codes on a CNC Machine
In this Instructable, I will be taking you through the steps I took to make this design on MDF wood Board using a Computer-numerically controlled Router machine.
Please, come along with me.
Supplies
MDF Board
CNC Machine
CNC Router bit
CAM software
Vector Graphics software
Step 1: Get the Desired Shape
Get the image of the shape you want to design with.
I got this particular shape from an Instructable; and downloaded one of the CAD drawings https://www.instructables.com/How-to-program-arcs-...
Alternatively, you can make a sketch of it on paper or draw it on a CAD Software.
Step 2: Import the Image Into Inkscape
I downloaded Inkscape v1.1 for the purpose of this project.
I imported the image into inkscape as a vector.
I then sketched on top of it using the drawing tools
Step 3: Export As .dxf File
Computer-Aided Manufacturing softwares recognise .dxf files or .bmp files
I exported the shape i redesigned from Inkscape to be imported into a CAM sotware
Step 4: Import Into CAM Software
Using Art CAM 20087, the result is as shown; after importing the .dxf file
You can alternatively use Lazy CAM or other softwares
Step 5: Set the Machining Conditions on CAM
Configure the CAM software to do the grooving/ profiling with the selected tool on the CNC machine
CAM softwares allow you to do a dry simulation; and so you can preview the outcome before machining
Step 6: Generate the G-Code and Send to Mach3
Mach 3 is the software I am using with my BETA CNC Router machine.
The CAM software can generate the G-codes as .txt file, .nc file, .tap file amongst other extension formats.
Ensure the dimensions (mm or inches) are accurate with the configuration on the CNC machine.
You can view the G-code mine generated from the link below
Step 7: Start Machining
I did a twin-replica of the shape i got online.
You can see the CNC output of the work in the pictures
Step 8: Are You Happy?
So, this happened to be my very first Instructable.
I am Timothy Aderogba, I just resumed a new position as Design Engineer few weeks ago; and I am getting on with my first-hand experience on a Forsun Beta CNC Router machine. You can look forward to more instructables from me soon. Follow me and let's connect.
I will be glad to hear you comments below.
Warm regards.
