How did you tune this oven? #13

Hi I have built this oven and it works so far. But I am unable to tune the PID Controller so i does not overheat and is able to follow the curve. I tried the CHR method but the results i got do not match the settings on the oven. What was your method?

Hi there, my method was quite easy, I used PID values from other users who build this oven in comments section Vulcans instructable. I just put them and it was working out of the box.:) TBH I did cosmetics changes using manual PID tuning, like described on wiki:

PID_Compensation_Animated

in my opinion it's not easy to calibrate when you don't have build in fan, low power heaters (below 1000W), non heat isolated chamber etc.

Hi thanks a lot I will try that, in school we learnd theoretically how to use the CHR method but that did not work well.
