I get the above warning in Octoprint when I log onto my printer.
I contacted Anycubic and received the following response.
Thank you for your email and support for ANYCUBIC. This is the ANYCUBIC after-sales technical support department.
We have enabled this feature in all firmware. You can see this in the firmware source code through this link.
"A pic of the config file is placed in the email"
I hope this can help you.
Have a good day.
Can anyone verify this?
