Restarting a cut

I am having the occasional problem of my cutter stopping in the middle of a job. Usually when I rerun it, it goes to the end. But sometimes it doesn’t. If I am in the middle of a 3d job it may have run for some hours before it stops so I really do not want to start again. Is there anyway I can get it to start where it left off. I usually get the message can’t connect with the cutter.

If you must do this:

  • note what line the machine is currently sending (or determine where it was by measuring the deepest area correctly cut)
  • pause, then stop the job and shut things downopen up the G-Code file in a text editor
  • identify the preamble and copy it — see G-Code for the details of the codes
  • go to the line # noted above
  • scroll up from there until you find a move down from safety height
  • delete everything from the line above that line to the beginning of the file
  • paste in the preamble at the beginning
  • save under a new name
