Breaking up large g-code into multiple jobs

What’s the best way to do this? I’ve got a fairly large project on the go and I would like to break it into several chunks.

It seems to me (please correct me if I’m wrong) that I should:

-Open the g-code file in a text editor
-Cut it into chunks and saved as separate g-code files, making sure the file is cut after a z lift
-Copy and paste the beginning and end g-code to the other files, so that each one ends with lift and a pause

So long as my work piece doesn’t move, I home with dual end stops at the start of each run, and I’m careful about setting the z height, this should work right?

Yep, that should work.

That’s one way.

I typically break my Gcode at the end of a process. If I’m doing a bunch of pockets, I’ll make sure it stops at the end of a pocket. If I’m cutting parts, I’ll end it after X number of parts.

With ESTLCam, I’ll create a few tool paths, then take a look at the simulator to see how long it will take. If it looks like it’s the right amount of time, I’ll run it through the post processor. Then start over with the next batch of cuts.

That’s a good idea, I didn’t think about it stopping half way through a pocket!

Thanks for the help guys, if this turns out it will be the first thing I’ve done that can go into the “Things You’ve Made” section. :slight_smile:
