What is the problem?
For a few years, I've had some custom controls in my Octoprint to position the nozzle for manual bed levelling, near the corners, but not so close I can't get to the thumbwheels to adjust. This is done in the config.yaml controls section. Works great!
However, recently (last 6 months or so?) I've had to recreate the controls after a reboot, or restart of Octoprint. Looking in the config.yaml, they are no longer present.
So now I keep a copy here, just to have a safe backup. octoprint levelling controls.yaml · GitHub
My current "fix" is to paste them back in and restart the Octoprint service. Then they will remain for a while.
What did you already try to solve it?
I thought perhaps the format for these controls had changed, but I don't see anything on the Custom Controls page of the manual about that. I did try to use the Custom Control Editor plugin, in case it had some magic that I didn't, but I just get a small empty green box, and no instructions.
Have you tried running in safe mode?
No - since (I don't think) it happens with every restart, I'm not sure how this would work.
