"outputStep" is not working correct about stune HOT 2 OPEN

Hello and thank you for your feedback.

The examples using the MAX6675 were for a PTC type heater. I plan on doing a revision later this year that includes examples using a regular thermal heater and provide improved documentation and easier to use interface.

Yes, sTune doesn't use setpoint while it determines the PID gains, so its important to set the tempLimit value prior to running the test.

To get more consistent PID numbers for a given outputStep (stepped power level), then its important that enough time has elapsed while resting at the outputStart value (power level) for the temperature to be stable before starting the test.

If needed, you can enforce a cool-down period between tests for the input temperature to stabilize. For example, use settleTimeSec = 1800; for 30 minutes cool-down time.

Hey,

that would be helpful! I also stuck on testTimeSec, outputspan and outputstep.
My environment: ESP8266, QuickPID, kettle (outputspan: 0..100% powerlevel, inductioncooker with seperat control functions), DS18B20 (inputspan 0..100°C). hints and tips are wlecome.
