As long as your work zero didn’t change, you can just click on the segment you want to start at on the visualizer. It will direct you to the corresponding line on the g code and you can click run from here or line one something like that.
If you click on the line on the screen, it should pop up a message asking if you want to run from “line” or “loop”. In this case you would select “line”, because you want to start somewhere other than the beginning of that cut loop. It should generate a new program that only shows the lines that are left in the program. Hit start.
I say “should”, because I’ve seen others have issues with the current version of Firecontrol not behaving as it should in this situation.
Another aspect to consider, your g-code only recognizes to types of lines - straight and curved. It will generate g-code by adding straight / curves as necessary to generate the program. Each transition will be a new line of code. Run from line “should” be able to select the line you’re on / next line and generate new code to continue. Occasionally, if your cut fails in the middle of a long cutting line, Run from Line starts in an area that has already been cut. And the next line is too far from where the cut stopped.
In this case I’ll edit the g-code (if you really want more info on this, PM me) to start where the cut stopped, and continue the line as expected. From that point, the generated g-code should be able to handle things.
