We do a lot of pen tracing, and we have found that when my cnc operator gets interrupted and doesn't remember to close the pen file and load the cut file we mess pieces up. SO is there a way I can have the gcode file automatically close after it is run ( I do realize the easy thing is to get in the habit of load programs correctly, but it is a mistake that can be easily done and cost money) . I was thinking this may entail putting a macro at the end of the program in the post processor. I don't have a clue how to do this yet so a copy/paste instruction and help would be great.
