hi. i am building a pellet extruder with 3 heaters and 3 k type thermistor(using max6675) connected to octopus board using ratos. Since the thermal mass of the extruder is too much, it takes some time to heatup. But as soon as i heatup within a few seconds ratos stops with this error "Heater extruder not heating at expected rate". How can i go around this?
