That's it. I'm not sure if I was running 1.0.317 or 1.0.312 before, but on the most recent version of Control, 1.0.321 as of this post, CAM cannot see the server. Control is working by itself, and I can also access it via browser at http://localhost:3000/ I'm just missing the connection between them. I'm running Lubuntu Linux 5.4.0-121-generic x86_64
Oh, I repeated the tet on my Mac, and it didn't work either... until it did. I could see somehitns about jquery complaining about https://mymachine.openbuilds.com:3001/workspace, but then it all came back to normal on the mac at least (I closed the cold cold shop for the night!) Happy 4th of July. See you in a couple of days then
An update will be available later this week to resolve an expired certificate. In the meantime use the Save Gcode button to download it from CAM (Floppy disc icon next to Generate Gcode button) and Open in CONTROL. Just one extra click
