Since 2010 making

Guitars for CNC


Front & Back (SS) file details

  • The files are separated into parts and front and back.
  • This makes it easier to use and understand the files.
  • The models are placed in a sufficient area for the part to be machined. You must adapt the model to your work area and in some cases rotate them.
  • Toolpaths are made according to each model. They are meant to be your starting point.

Files are usually organized as:

  • Body front
  • Body back
  • Neck front
  • Fretboard
  • Neck back

  • Neck front complete with fretboard is sold separately

Double Sided (DS) file details

  • These files are made using the Double Sided version feature.
  • This type of version allows you to have both sides of the guitar in one file. This facilitates the visualization and understanding of your machining simulations and helps you to identify possible errors.
  • These files have all vectors and toolpaths which can cause some confusion in understanding the file if you are not experienced in Aspire or VCarve.
  • Toolpaths are made according to each model. They are meant to be your starting point

Files are usually organized as:

  • Body Front and Back
  • Only Neck without fretboard Front
  • Fretboard

  • Complete Neck with fretboard Front and Back  is sold separately

An important note about Vectric's 3D simulation in the double-sided version.

As we well know Vectric software is not great with 3D machining. They do the job a little rough.

The 3D component resolution even at 50X does not make the 3D machining as good as we see on a Fusion 360 or RhinoCAM.

The 3D simulation of the two-sided mode is precarious and doesn't exactly correspond with reality and it causes distortions in our imported 3D files.

Vectric is a software best suited for artistic work and a little technical and the guitar I consider a highly technical work.

So what we have here are CNC guitars from small manufacturers where they have experience in making them in the traditional way also to be able to compensate for the software's failures.

Truss rods

as standard all neck receive the 2 ways truss rod.

As there are some different radius, positions, diameters, anchor nuts, access at the headstock or heel neck, I prefer not to provide the old truss rod stylus

I did a video showing how to do that and then each one can do it as they wish.

Go to the Youtube to see it better and use it controls.

If you have some questions about this tutorial, please write it below the video on Youtube.

Enjoy subscribes because after 1000 subscribers YouTube will provide some nice special resources for the subscribers. I want to make Live and offer videos with material training exclusive for subscribers.

Order your back truss rod old style

If you prefer order your own model for the guitar you bought with us, please let us know written to


As a standard, milling cutters are the most common and made with a reduced number of sizes to make it easier for those who do not have much bit diversity yet.
For those who are already used to machining on their CNC, it will be easy to understand the operating mode used in the files and will begin (if they wish) to modify, increase or even replace the toolpaths.

The speeds by standard is slow and the step over and plunge steps are minimal, thinking about the safety of the user and the care with more fragile machines.

Make initial tests and observe the behavior of the bit movements and make the necessary changes.

Read carefully about the models you want to buy and download the sample for testing.

Neck files

As standard the neck is:

  • Neck front and neck back without fretboard (if Front & Back sides SS) including the channel to insert a 2 ways truss rod like a Stew Mac model.
  • Neck front and back sides into the same file (if Double Sided version DS) without fretboard with the Stew Mac truss channel.
  • Fretboard

If you want the neck and fretboard together in the same file you can buy this file separately.

Opening a file, the notes window automatically appears.

There, some basic instructions will be provided.
When you no longer want it to open, delete the dot at the top of the window


In the Drawling Tab, in the Job Setup option, the size of the sacrifice area houses the work elements as closely as possible.
You can modify it to your liking as well as the Z ZERO Position, XY Datum Position, Resolution and your favorite viewing color.


On the other side you can modify the height of the material and
configure the bit output, dip position, etc.



In the Layers Tab, the vectors are divided by elements that make up the guitar such as
Body profile, Roughing area of ​​the neck rest, control box, etc.
Some layer names correspond with the names of the Toolpaths.


In the Molding Tab you will find the surface of the corresponding guitar part with the file name.
Generally and in most cases the surfaces have no cavities. This is best if you want to modify something.
On Aspire, you can use your knowledge in it to make changes or unlike VCarve, Aspire provides you with the possibility to create other elements or even import from other auxiliary software.

In the Toolpaths tab you will find the toolpaths simple enough for your immediate understanding, but sufficiently effective in the machining of your guitar.


Toolpaths are intended for novice users, but it is extremely important that you have prior knowledge in using your CNC as each machine combined with each cutter and different types of wood, behave differently.



Enter Edit on the route and modify the parameters to best suit your machine.
Change the material height if necessary, check if you have the same cutter or if you want to use another one.
Change what you think is best to make it better for your CNC.
So it is important if you have no previous experience with your CNC, that you use cheap wood as a test and use the slow speeds to avoid accidents.


More complete machining can have dozens more toolpaths. Feel free the desire to do as many more as necessary. Or just use the ones that are already in your file.
