![]() * (Marlin uses the term MAX_FEEDRATE, but I think that’s confusing, so I’m always calling it “max speed” in this writeup. Some example G code for moving around: Move to 100,100,0: This is the F#, like F15 on a G01 command. There is also a "Feedrate" that can be set with each movement command.Marlin also has a "jerk", but it is not the derivative of the acceleraion, more on that later. ![]() ![]() The configuration for grbl and marlin have a max "speed", "acceleration" defined for x, y, and z.(((I don't like to say what is "meant", but grbl acts this way, and Marlin was originally based on grbl, so I'm going with that))) G00 is "meant" to be repositioning the bit somewhere, to do more cutting later.Linear in this sense is like a line, as in not the arc commands. G00 is a "rapid" movement command, G01 is the "linear move" command.This is mostly from the viewpoint of CNC milling, not 3D printing. I’ve found some things that have been a little confusing, but I think I’ve got to the bottom of it all, and I wanted to share what I’ve found. I’ve been doing some investigating, using a grbl setup on my desk.
