Hi! Do you get constant output while tunning period? Cause I do and doubt is it ok.

What do you mean by "constant output"? Output is in green color in the plot.

Try apply more heating power.

@@DIY-electronics-automation I mean my output never grows more than 25 and get stucked on that number with outputSpan even 1000 and outputStep 50 during tunning period. And I get inadequate results of kp, ki, kd. I'm not familiar with PID tuners. Now I get it, according to your video, that I've got issues somewhere. Maybe with my MAX31855 readings.

@@jackblack7132 I see, you may want to verify if MAX is reporting the temperature correctly; by checking the "input" curve in the serial plotter.
