G-code and M-code are the foundational languages that drive CNC (Computer Numerical Control) machinery and 3D printers.

A printer is essentially a sophisticated plotting machine that moves to certain coordinates told to it by the slicer in the programming language G-code. That's why slicer software is so important.

How do 3D printers work? What's the impact on our economy? How expensive are they compared to traditional manufacturing? We take a three-dimensional look at the world of additive manufacturing.

At this point, you can basically track any G-Code command and also insert arbitrary new G-codes, for example G1 printing moves (for wipe towers) or M280 commands to control a servo.

When a print job is finished, custom G-code causes an attachment on the printer to wedge itself under the build plate and peel it off until it is freed from the magnetic bed, after which the ...
