Learning G code, courses etc

So I’ve seen some basic tutorials, a few YouTube courses etc. Does anyone know of a really good course for learning the ins and outs of G code?

I’m not just interested in 3d printers, but cnc machines as well.

HI would check Udemy first, they are usually my go to for initial learn on any topic

The Marlin development team lists a few recommendations for resources on their GitHub page, under the Marlin Support heading.

GitHub - MarlinFirmware/Marlin: Marlin is an optimized firmware for RepRap 3D printers based on the Arduino platform. | Many commercial 3D printers come with Marlin installed. Check with your vendor if you need source code for your specific machine.

A quick search on Google provides a lot of relevant hits, like this: g code training online - Google Search

Udemy offers a large number of gcode courses which are often on sale for low prices like $19.99 Cdn.


I honestly had never heard of udemy before joining here.

I checked them out before heading off to work this morning. Think I’m going to have to try out some courses.

@Benchy its been my go to for years, especially starting into raw programming, or trying a new language, sometimes just get board and stretch the brain a bit

You can usually find a suitable course at a low sale price. Try not to ever pay full price. Sales happen often, though time-limited.

Coursera.org & edX.org are two other favourites of mine.

You may also enjoy Scribd.com, which is a subscription-based service with access to text books, hardbacks, paperbacks, audio books, magazines, etc., for about US$9/mo.
