Is this you?

Stressed machinist at CNC control panel

You are standing in front of a CNC machine, staring at a program, not fully sure what every line is doing.

You know how to press cycle start. You can tweak a few numbers. You can usually get a part out.

But deep down, you do not really understand what the code is telling the machine.

Maybe you were taught to copy the last job. Maybe someone showed you which buttons to press. Maybe you were handed a proven program and told not to touch it.

So you run parts on faith. You hope the offsets are right. You hope the tool moves where you think it will. You hope nothing crashes when you press start.

That uncertainty leads to:

  • Second guessing every edit you make
  • Slow setups because you do not trust your changes
  • Fear of touching G-code in case you break something
  • Feeling stuck while others move on to better jobs

I know that feeling well.

When I first started, I could run machines, but I did not understand them. The code looked like a foreign language, and no one had time to explain what it really meant. I learned through mistakes, wasted parts, and long nights wondering why things went wrong.

The problem was never ability. The problem was never intelligence. No one had ever given me a proper foundation. That is exactly what this course gives you.

If you are still guessing at the control, you are not alone

Maybe you have started learning G-code. Maybe you are using CAD/CAM and tweaking programs on the machine.

Maybe you are running parts every day but still feel unsure when you make changes. Without a solid foundation, everything feels harder than it should.

Programs take longer to prove out. Edits feel risky. Sometimes a small change causes a big problem and you do not know why.

So you copy old code. You avoid touching certain lines. You hope the machine does what you expect.

That slowly eats away at your confidence, even when you are doing most things right.

When you understand how G-code, coordinates, tool offsets, speeds, feeds and machine behaviour all fit together, things finally make sense. You stop guessing. You start predicting what the machine will do. You make changes with purpose, not fear. That is what a real foundation feels like at the control.

Introducing: The Foundation to G-Code Course

Better Career Prospects

Mastering G-Code as a CNC turner can open up more job opportunities, making you a more attractive candidate to employers. This can lead to higher salaries and better job positions.

Improved Efficiency

Learning G-Code can help you write more efficient programs, reducing machine downtime and increasing productivity. G-Code is often much quicker than CAD/CAM when programming lathes.

Access to Resources

Enrolling in the course provides access to valuable resources and reference material that you can refer to long after completing the training. Revist the content as often as you like, for life.

Greater Job Security

Having in-demand skills can provide greater job security as you become an invaluable asset to your company.

Less crashes, more confidence

Proper training helps reduce programming errors, leading to fewer machine crashes and can boost your confidence in handling complex machining tasks.

Enhanced Creativity

Understanding the intricacies of G-Code allows you to get creative with your machining processes, leading to innovative solutions and designs, quickly making you the rockstar of your shop.

G-Code is the programming language of CNC Machines. It is made up of GCode commands and MCode commands that look like 'G00, M01' with positional commands that tell the machine where to move to. It is a lot easier than learning a programming language such as JavaScript or even HTML!

With this GCode tutorial course, I will guide you through this fascinating programming language so that you feel confident machining parts using your CNC Router or CNC Mill.

Each G-CODE and M-Code command is discussed in easy to follow bite-size lessons with example programs to make learning to program GCODE easy.

This GCode tutorial covers a range of different subjects providing you with a complete foundation for programming your CNC Machine.

  • GCODES and MCODES
  • Machining lines and radius
  • Cartesian coordinate system explained
  • How cutter compensation works
  • Climb milling vs conventional milling
  • And many more
  • The Course includes 4 full programs!

    Excellent, Highly recommend. Great to get a basic idea of G-Code.

    Brian

    A great introduction to CNC machining using G code.

    Paul

    This course really painted a picture in a way that allowed my brain to absorb the information Marc presented. Having little to no experience in the machining world, he broken the basics down step by step and I now understand how the Gcode program works. I feel more confident looking at an arc and translating the numbers into the Gcode format. Thank you Marc, I look forward to creating my first project.

    Geoffrey

    I'm moving into a new job role which requires CNC maintenance and repairs and understanding the programming side really helps solidify my small knowledge about how CNC works. Really good course for beginners like me and enjoyed practicing on the G code simulator and access to the machinist handbook is also fantastic! Highly recommended.

    Stevie

    This course gives a quick insight into G code programming from a complete beginners point of view, the step by step tutorials are well explained & simple to follow.

    Robert

    Marc's courses at G-Code Tutor are an absolute game-changer for anyone like myself who is entering the exciting world of industrial CNC operations. Whereas typical textbook instruction can be confusing and frustrating, Marc's clear, easy-to-follow, and step-by-step courses will take any motivated student as far as they wish in firmly grasping and utilizing machine code programing in their workplace. The courses are enjoyable and keep your interest and motivation all the way through. I'm so thankful for these courses and I recommend them highly to anyone.

    What you will learn

    This course takes you from zero to confidently writing and understanding real CNC programs.

    You start by learning how the machine thinks. That means the Cartesian coordinate system, how tools and offsets work, how movements are commanded, and how the controller reads a program. You will understand exactly what every line of G-code is telling the machine to do.

    From there you move into practical machining skills. You will learn how to position tools, cut straight lines, program radii and profiles, use cutter compensation, and control the spindle, feeds, and basic machine functions. You will also learn the difference between absolute and incremental programming and when to use each one. This course is part 1 of the complete G-Code training bundle.

    Next, everything gets tied together in full programs. You will write real milling routines for facing, slotting, and profiling, just like you would on the shop floor. You will see how professional programs are structured and how each section fits into the bigger picture.

    At the end of the course you will program a complete part from a drawing and submit it for personal feedback. This is where all the theory becomes real, and where you gain the confidence to write, read, and modify CNC programs without guessing.

    By the time you finish, you will not be copying code and hoping it works. You will understand what the machine is going to do before you press Cycle Start.

    Here are the lessons and bonuses that you will get when you purchase this course.

    Foundation to G-Code Course: Value $147

    Sick of running programs you do not fully trust? Most people are taught how to push buttons, not how the code really works. That leaves you guessing, copying old jobs, and hoping nothing goes wrong. In the Foundation Course, you learn how CNC machines think.

    You will understand how to quickly write G-Code to make basic parts so you can see exactly what will happen before you press cycle start. Inside the course you will learn:

    • How G-code tells the machine where to move
    • How coordinates and offsets control every toolpath
    • How to make safe, confident edits to any program
    • How to spot problems in code before they become crashes

    This is the base that every lathe, mill, CAM system and setup builds on. Once you have this foundation, everything else becomes easier.
