Starting job at the point of disconnect?

Is there any way to do this?

Not automatically.

You can make note of the last line successfully sent, then manually edit the file, preserving the preamble and deleting everything between it and the move down from safe height before the last line sent.

Doing this in C motion? Text editing?

Universal G-Code Sender has a specific feature for this: Usage · winder/Universal-G-Code-Sender Wiki · GitHub [*]

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 down
  • open up the G-Code file in a text editor
  • identify the preamble and copy it — see GRBL G-code definitions 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

What I do (usually). Take notice of the Z depth. I go into CM and change the Z height (START) a few thousands above the Z depth when the disconnect happened, and make a new program. Clear?
