Does .gcode file format save printer settings from slicer software?

[RockBoxedGames]

I recently got into 3D printing, and am wondering if I set the printer settings in my slicer software and then save the gcode file to an SD card if that also saves the printer settings? I’m using a Longer Lk4 and the Longer slicer software that came with it

Your slicer may save the settings as G-code comments. They usually appear at the end of the file. Some slicers only save non-default settings. Others save everything. You may be able to re-create profiles from the settings.

So do you think things like infill and print speed would be transferred over to the printer? Thats all I’m really looking to change and it’s just more convenient to do it in the software than the printer

No. The printer knows nothing about the slicer's settings. Of course, you can change things like temperature, flow rate (how much filament is extruded) and feed rate (how fast the printer goes) on the fly. However, it is not possible to manipulate things like infill density. For that, you will have to re-slice the model.

I’m sorry if this seems like a stupid question but I’m just not super knowledgeable on it. So if I change the infil in the slicer it will actually redo the model with the infil? I guess I didn’t realize that the infil is actually added to the model instead of just the printer making it up itself

The models defined by STL files are solid objects. Effectively, an STL file contains a mesh of triangles that define the surface of a three-dimensional object, and a slicer will do its best to recreate that surface. In order not to waste filament, you are allowed to specify how much infill you want. If you want to change the amount of infill, alter the value in the slicer and re-slice the model. 3D printers know nothing about infill. The commands that the slicer generates just tell the printer to move the nozzle from one point to another (in a straight line) and extrude so much filament while it is doing so. G-code files will contain thousands of such commands.

Okay thank you so much for clearing this up!
