In this review we take a look at GCodeTutor’s course on CNC router programming for hobbyists.

This course is split into two halves, the first part explains how to use fusion 350 CAD/CAM software and how to make models and export the G-Code from Fusion to your CAC Router.

The second half looks at that G-Code file, and how to edit it and even reprogram by hand if need be. So this course really does do what it says on the tin, it teaches every aspect of CNC router programming.

Fusion 360 CAD/CAM

The lessons start off with an overview of the parts of Fusion 360 that is used by CNC router owners. The menus, view system and controls are all explained before we started to make our first 3D model.

As we start to make the first easy model, everything is explained as a machinist. Even setting up the working environment is done with the Z-Axis up so the model can easily translate into the programming language that is understood by your CNC router, G-Code.

Once the model is made, we then go into how to produce tool paths and selecting the correct cutter to use for each feature, including the correct cutting method for each. This is where Marc’s expertise as a CNC machinist really stands out. Everything is explained with inside industry knowledge as you are guided through making parts for your CNC machine.

After each model is produced, Marc then moves on to explain how to post it to your machine and output the gcode file.

G-Code Section

About 2 and a half hours into the course, once we have a solid knowledge of how Fusion 360 works, we start learning about how to write G-Code, the actual language of your CNC router.

At first, we thought that this information was not needed since we use CAD/CAM to produce our parts, but we were wrong.

G-Code is not difficult to understand, especially after taking the second part of this course, and it has made my life so much easier with my machine. Every problem I have had in the past could have been solved quickly and easier if only I knew G-Code before.

We learn how to edit programs, split them into multiple programs and even how to write simple parts just with code, and its great fun to see your machine cut a shape that you programmed by hand. Probably the most satisfying part of being a CNC router owner so far I would say.

But does he teach it well?

Marc goes into great detail but also explains things in a clear and easy to understand way. We had no problem keeping up as the pace of the course is just right, there is no fluff, it’s all information and advice from one of the worlds most well-known CNC machine tools tutors.

The tutor has some credentials to back up his expertise.
Before Marc started GCodeTutor, his CNC programming website, He worked as an aerospace CNC engineer for over 28 years and also writes for Practical Machinist magazine.

Conclusion

All in all this 4-hour course has really improved my knowledge of my CNC machine. I am much more confident that I can make any shape I wish and problem-solving has become a breeze after learning how to program G-Code.
