Maximum Temperatures
By default, the maximum temperatures allowed by the firmware are set to the maximum
safe operating temperature of the PTFE-lined hotend, which is 260°C. If you want to
increase this while using the all-metal hotend, touch
> Temperature > Hotend 1 Setting
> Max Temperature and enter a value at least 5°C higher than the desired target
temperature to allow the PID to function properly.
