The "N" indicates line number and can start at any number it's generator is programmed to start at.
G1 is move to coordinates X=72.13 and Y=225.089 and E11.43  (E=height, most gcode uses Z instead of E).
F9000 is speed of 9000 and the "*" can be a custom comment or a multiplier, depending on the gcode generator and firmware (gcode can't actually do math - gcode is simply a text file for the firmware to respond to).

Google gcode and learn the basics - it's straight forward and simple...

Would not E mean to extrude 11.43.... mm of filament along the specified axis?

Re: Print Speeds

Carl, The answer to your question is 'Yes', sort of...

Recognize Gcode has been around for many years and was developed for CNC and knew nothing about extruders.  In the beginning, some Gcode interpreters used "E" for speed on Lathes, some used it for "Z" position, others used it for other commands relative to their (or specific) machines.

In the case at hand, a 3D printer, "E" can mean anything the gcode interpreter coder wanted it to be and, possibly for Extrude, in this case.  However, I can't say without looking at more of the code - if the code contains "Z" elsewhere, then the "E" would probably be for Extrude.  If no "Z", then it would be for Z-axis position.

There a many sites /  books on Gcode, but it's important to recognize that 'some' commands change with respect to the developer of the interpreter.  Here's a link to wiki, it shows "E" for lathe feed rate. https://en.wikipedia.org/wiki/G-code  and, here's a link to RepRap http://www.reprap.org/wiki/G-code  - read down the page and you'll see comment about writing your own Host software (the point being, "E" or "Z", or what ever, can be different things to different developers.  There is a universal specification for gcode to use as a baseline and most follow it.

Re: Print Speeds

Thanks Galaxy!! I will do that!

I was lucky, and altered my Gcode and saved my first big failed print several times. The seams were a bit ugly, but for my very first print, and doing all that, I was extremely impressed with myself lol. I look forward to getting more into it, and understanding what I'm actually doing with it.

Filastruder and Filawinder - soon enough
