If the file is not locked, then the file reload should work perfectly for me. I just assumed an ope file would be locked and never tested it. The one thing that's bugging me about Linux, the Linux Mint GUI file manager has only the file dates, not Date/time. Even when you click on properties, no time is displayed that I can find. I want to see the time to know that this is the new file I just updated, not the one from 15 minutes ago. In Mach 3, the load file control showed the created date & time so I got the assurance the newest g code file synced down from dropbox.
In reality, by the time I get back to my CNC, the file should be synced and I can simply click the reload button and run with my CAM updates. The fact that the file is not locked is a big improvement in my workflow as I would often forget to close the file before I went upstairs to make my CAM change. Then the file would not sync as Mach 3 locked the file.
Thanks!
