If I go into control and click either preheat hotend or build plate at times 190 shows for a split second then drops right back to zero. Sometimes this is just after printing with no problem. If I reboot octoprint it works correctly. What could be causing this?
What did you already try to solve it?
Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware,
serial.log or output on terminal tab, ...)
