You can drop any block of g-code into your slicer, but that would require running the file to get the commands to run. In Klipper, you can just run the macro.
For example I've got a "enclosure heat" macro that
Sets bed temp to 100 and extruder to 280
Turns all fans to max
Moves my print head in front of my webcam (there is an ambient temp display on the print head)
I can do all of these manually, of course, but with a macro I can just push a button and it does all of it.
It also makes it so you don't have to paste those entire g-code command blocks into whatever file you're slicing, and so that you can retroactively change commands. (Instead of having the entire startup sequence at the beginning of every g-code, I have a "START_PRINT" macro at the beginning; if I change the macro, all of the files I already sliced will have the updated behavior).
Oh, that's neat and I can certainly see why that's useful.
I have to do a little gcode header swapping by hand because I'm cheap and bought a p1p and am certainly making it do things it's not really designed to do, and that kind of functionality could save a bit of time.
You can run and save custom gCode on Bambu printers. I've got a cold pull script that lives happily on my x1c, and can be triggered any time
I don't use Bambu printers, but don't they use a modified version of gcode and still refuse to let anyone see the documentation?
Nope, they still use bog standard gCode, but they do have some custom commands for things that are unique to the printer
