Which of these is the correct start code for my GCode to begin? Or is there a different start code?

This comes from a converter at: https://www.cnctoolsworld.com/application-all_to_g_code_converter_free-2.html

“It was a dark and stormy night…”

A bit cliche’d, but a classic.

If that’s not your style, then this is what I have in Estlcam for Program start:

;Project <project> ;Created by Estlcam version <version> build <build> ;Machining time about <time> hours

Once upon a time, long, long ago, there was a… Which works just as well. LOL

Last night I made my waste board. Well, the cuts made it obvious that my board wasn’t level with the machine. I corrected the issues and tried to go back over it again. It went halfway and then it stopped moving and stayed in one hole.

I shut down, reset X0Y0 and started up. This time it acted like I had rotated the waste board 90 degrees. I shut down again, changed my XY around in Ramo, started up, reset to X0Y0 and believe it or not, it did the same thing going to the same place… It was like I didn’t change the XY direction. I shut down and changed my cables back, reset XY and it still does the same thing. I think the code is corrupted.

I’m going to delete the file off the SD card and replace it with the original.

With all that, can the program make its own changes like that? My fairytale turned into Nightmare on Elm Street! lol
