What is the problem?
Installed Octopi on a RasPi 4, connected to an AnyCubic Kobra Max. Seems to be working until changing the temperature of the tool or bed. It makes a constant loud beed/alarm until the temperature of the bed is within +/- 2 degrees of the set temperature.
What did you already try to solve it?
Have you tried running in safe mode?
Reinstalled octoprint, reconfigured, and tried sending some G-code manually. Researched the firmware versions, requested help on Discord, no luck. Printer came with 2.8.7 firmware, but latest on the Anycubic Website is 2.8.6. Not sure if that's the problem, and hoping for a little help in what the difference might be, or if there is a setting I need to disable. I disconnected the LCD attached to the printer, but the annoyance comes from the motherboard.
Did running in safe mode solve the problem?
