Hi Jon, I did this years ago. It is really pretty easy as the emc docs lay out modal G codes pretty well. It really isn't too many lines of code. Unfortunately, I cannot find the source and at one time it was in the dropbox but could be retrieved today only if someone happened to find an old archive.
IMO the way to do this is a script that runs the program to find current state. Makes Gcode out ot it. Cats this in front of the remaining lines of the program and starts it ... at the end of the run deletes the temp run file and you are done. Now to fine someone bright enough to do this. I can do the first part but not the rest or it would have happened by now. ;-) Dave On Feb 4, 2009, at 10:54 AM, Jon Elson wrote: > Tom wrote: >> Hi all, >> >> In an earlier post I commented on pausing Emc2/Axis in the middle >> of a cut in >> order to clear swarf and the problem of using the "stop" button >> which turns off >> the spindle and coolant: how to "set next line" and resume where >> you left off >> when the spindle and coolant are off?
