* If you get false positives for "Thermal Runaway" increase THERMAL_PROTECTION_HYSTERESIS and/or THERMAL_PROTECTION_PERIOD */ #if ENABLED(THERMAL_PROTECTION_HOTENDS) #define THERMAL_PROTECTION_PERIOD 60 // Seconds #define THERMAL_PROTECTION_HYSTERESIS 6 // Degrees Celsius

I would put the period back to the original settings and increase the hysteresis to 8. However, before you increase the hysteresis, make absolutely sure that your part cooling fan is blowing below the tip of the nozzle, and not onto the nozzle or extruder heater block. If it blows onto the block it can affect the temperature and may cause similar problems. If you have an extruder cooling fan, then make sure that the heat-sink fins are horizontal and not vertical for the same reason.

I've now bumped it to 120 for the period and 10 for hysteresis. Your suggested mods found failure at identical location as previous.

What filament were you printing, ABS or PLA, and what were the target temperatures for bed and extruder? I assume with the bed showing an actual tempeature of 86C that it was ABS. Some hot bed / PSU combinations are under powered and struggle to get the bed above around 86C unless in an enclosure. If your target bed temperature was above 86 this could be what has triggered the failure.
