I'm getting the same error. My process:

• From a clean boot (with autostart turned on)
• Confirm web interface is active, thermocouple and SSR are functional (using pre-built scripts)
• Via SSH systemctl stop kiln-controller Output:

pi@kilnpi:~/kiln-controller $ systemctl stop kiln-controller ==== AUTHENTICATING FOR org.freedesktop.systemd1.manage-units ==== Authentication is required to stop 'kiln-controller.service'. Authenticating as: ,,, (pi) Password: ==== AUTHENTICATION COMPLETE ==== pi@kilnpi:~/kiln-controller $ python kiln-tuner.py recordprofile zn.csv Could not import config file. Copy config.py.EXAMPLE to config.py and adapt it for your setup. pi@kilnpi:~/kiln-controller $

config.py is present in the folder

pi@kilnpi:~/kiln-controller $ ls config.py kiln-tuner.py requirements.txt test-output.py docs lib start-on-boot test-thermocouple.py gpioreadall.py public state.json venv kiln-controller.py pycache storage watcher.py kiln-logger.py README.md Test ziplogs

can one of you comment out the try/except block near the top of kiln-tuner.py? post the error.

What I'll likely do is remove this try/except block so that folks can see what the real error is.

Confirmed getting same error och29

[jbruce12000]

This is an old branch and old version. you need to grab the latest code. I did a simulation on the head of the main branch and found a bug... then fixed it.

Getting same error with fresh dl today????

[jbruce12000]

post the output of:

source venv/bin/activate
./kiln-tuner.py

The kiln-tuner parameter handling was changed last Dec and should no longer be called like this:

kiln-tuner.py recordprofile zn.csv

The default is now to save to tuning.csv. If there is existing documentation telling you to call it this way, lmk so I can fix it.

[och29]

Thanks for the quick response, I suspect we're both using this documentation: https://github.com/jbruce12000/kiln-controller/blob/master/docs/ziegler_tuning.md#step-1-record-temperature-profie

To record the profile, run:

python kiln-tuner.py recordprofile zn.csv

[jbruce12000]

The master branch is no longer supported. The main branch is now the active, supported branch. Switching branches may cause you some configuration or hardware re-work because it uses blinka instead of libraries I manage.

cd kiln-controller
git checkout main
git pull

[och29]

Ah, then it's an issue with the link here then! https://github.com/jbruce12000/kiln-controller?tab=readme-ov-file#pid-tuning

[jbruce12000]

fixed the README. All links that pointed to master or blinka now point to main.

good find. lemme know if tuning still does not work for you.

[MeltTechAu]

Legend jbruce thank you so much have a great day mate!

[jbruce12000]

@MeltTechAu how did that tuning work out? any problems?

[jbruce12000]

closing. create a new issue if you find a new problem with the code or docs.

[och29]

I have tested this now, confirmed solved.
