As far as I know, you can't open the file in Aspire or VCP once the gcode has been generated. Sorta like pouring concrete. Once it gets hard, it's a done deal. However, you can open .ngc files in a text editor and make changes to the code if you know how. I don't have that skill.

Now saying that, I may be wrong.

A fantastic, readily available text editor is Notepade++. It is freeware that can be found by googling the name. It will open pretty much any file type.

The nice thing about it is there are many plugins available that help with the type of programming language being used.

There are several for cnc machine code (g-code) that will automatically color code all of the different g/m codes to help read the code. Such as G0 moves being in red, and G01 moves in blue, etc.

Like everyone else says after it is in gcode form you have to open it in a word processor and manually go through the file and rewrite code like they did many years ago before code generators were developed.

Ron you should be saving your Aspire design files then you can open that file and make any changes you need to make then recalculate the toolpaths. Save the new toolpath and run it on your CNC.

can you guys actually READ G code?? I just watch all the numbers spin by....and try not to hurt my brain. thank goodness for G code building software.

I remember giving up on computers in 1977 in college when we had to design stuff in fortran and use punch card machines to write code.... was certain than that they would never catch on..

I can read it but it is really boring. It has no story line. It's just up, down, back and forth using a coordinate system and it all ends where it started..

Dang Scott!!, I didn't start computing till 1982.
I still have my old Commodore-64 in the closet. 🙂

My daughter started grade school and they had a deal to get Commodore 64's. Our first step into the future. Weren't they around $500 then?

Favorite game was sreddal --- ladders spelled backward.

My first exposure to computing was "Introductory to Micro computers" in my first year of college. The computer was an IBM 360...about the size of a 48 inch dual wide belt sander!!! Yep, punch cards.

We may be straying from the OP a little but, yes they were really expensive in 1980s $$$ the 1541 5 1/4 floppy drive was $350 but it was great to not have to rewind the cassettes. 🙂
FF from 1990-2002 and the Packard Bell 386, then 486dx then Pentium Pro.......... Then I got the Network Analyst job with the state and all that time and money finally paid off but my "hobby" turned into "work" 😞
Now I'm retired and woodworking but with the CNC, I can do both. 🙂

Four c64 and two c128, two 1541 drives and a 1581, a couple of printers and 2 monitors and all kinds of games and software. It is interesting this came up because they are bring out a mini C64 that looks like the original but operates as a game system with some preloaded games. You can add a usb keyboard and program it like the old units. They also plan a full sized version of the system. They were suppose to be released this year.

Back to the original post.

You can edit gcode but it is no fun and a lot of trouble. The new code generating software like Aspire and VCarve is a great time saver and improvement over writing gcode by hand.

You should always save your design files so you can make changes if you find that the project has problems. You might also find that an old file might just work for another job with a few quick changes and re-running toolpaths.

Bringing Ron's original post back up it appears his old files only exist in .ngc form, with no orginal design available. UGH. No wonder I make regular backups.
