It is a stand-alone python script that, every few seconds, verifies the kiln-controller.py process is running, and within a certain acceptable temperature range. By default it checks every 10s and after six failed checks, it sends a message to a slack channel. It will send a message every 60s until the problem[s] are solved. It can run on any network, but needs to be able to access the kiln and slack. 4 | 5 | Here are the configuration items to potentially set in that script: 6 | 7 | | Variable | Purpose | Required | Default | 8 | | ------------- |-------------- | --------- | ------- | 9 | | kiln_url | the url of the stats api endpoint | Yes | None | 10 | | slack_hook_url| the url of the slack channel to post failures | Yes | None | 11 | | bad_check_limit | send message after this many failures | No | 6 | 12 | | temp_error_limit | consider it a failure if temperature is this far off | No | 10 | 13 | | sleepfor | wait this many seconds between checks | No | 10 | 14 | 15 | ### Slack 16 | 17 | [Slack](https://slack.com/) is a free messaging platform. It is used to send alerts when the watcher finds problems with your kiln. 18 | 19 | 1. Sign up for a slack account 20 | 2. Create a workspace, doesn't matter what you call it 21 | 3. Create a channel in that workspace 22 | 4. Set up an [incoming web hook](https://slack.com/help/articles/115005265063-Incoming-webhooks-for-Slack) in that channel. 23 | 5. Grab the URL for that web hook and use it to set the slack_hook_url in the configuration 24 | 25 | If you configured slack, you can test it by starting the watcher without the kiln-controller running and after six failures to reach the kiln, it will send a notification to slack. 26 | 27 | I have the slack app on my android phone. This enables me to receive notifications every time I receive a slack message on a specific channel.

It was a major change with all new classes. Lots of libraries were removed and the Adafruit blinka library was chosen which allows for a hundred or more supported boards in addition to raspberry pis. 9 | 10 | ## Why Swap? 11 | 12 | As of 2023 I stopped supporting and adding features to the old code. It still works, but I no longer use it, update it, test it, or change it. 13 | 14 | ## Easiest possible migration 15 | 16 | The easiest way to convert from the old code to the new is to use software spi, also known as bitbanging, to grab data from the thermocouple board. You will not have to make any wiring changes. You'll only need to change config.py and test it to make sure it works. 17 | 18 | 1. make a backup of config.py. You'll need it for the next step. 19 | 20 | ``` 21 | cp config.py config.py.bak 22 | ``` 23 | 24 | 2. update to the new code 25 | ``` 26 | git checkout master 27 | git pull (maybe force here???) 28 | ``` 29 | FIXME - need instructions on branch names to checkout etc. 30 | 31 | 32 | 3. Install all the libraries that the new code uses 33 | 34 | ``` 35 | cd kiln-controller 36 | source venv/bin/activate 37 | pip install -r ./requirements.txt 38 | ``` 39 | 40 | 4. find these settings in config.py.bak and change them in config.py: 41 | 42 | ``` 43 | gpio_sensor_cs = 27 44 | gpio_sensor_clock = 22 45 | gpio_sensor_data = 17 46 | gpio_sensor_di = 10 47 | gpio_heat = 23 48 | ``` 49 | 50 | change them in config.py to look like so: 51 | 52 | ``` 53 | spi_cs = board.D27 54 | spi_sclk = board.D22 55 | spi_miso = board.D17 56 | spi_mosi = board.D10 #this one is not actually used, so set it or not 57 | gpio_heat = board.D23 58 | gpio_heat_invert = False 59 | ``` 60 | 61 | 5. test the thermocouple board and thermocouple 62 | 63 | ``` 64 | ./test-thermocouple.py 65 | ``` 66 | 67 | You should see that **software spi** is configured. You should see the pin configuration printed out. You should see the temperature reported every second. 68 | 69 | 4. test output 70 | 71 | ``` 72 | ./test-output.py 73 | ``` 74 | 75 | Every 5 seconds, verify the output is flipped from on to off or vice versa. 76 | 77 | 78 | -------------------------------------------------------------------------------- /public/state.html: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | Kiln Controller 5 | 6 | 7 | 8 | 9 | 10 |

It settles quickly from any oscillations and hovers really close to the set point. What do I mean by close? The average error for my kiln on a 13 hour schedule is .75 degrees F... and I have a noisy thermocouple, so it is possible to do even better. 10 | 11 | ## The Tuning Process 12 | 13 | ### Automatic Tuning 14 | 15 | Contributor [ADQ](https://github.com/adq) worked hard on creating a [Ziegler Nicols auto-tuner](ziegler_tuning.md) which is python script that heats your kiln, saves data to a csv, and then gives you PID parameters for config.py. 16 | 17 | ### Manual Tuning 18 | 19 | Even if you used the tuner above, it's likely you'll need to do some manual tuning. Let's start with some reasonable values for PID settings in config.py... 20 | 21 | pid_kp = 20 22 | pid_ki = 50 23 | pid_kd = 100 24 | 25 | When you change values, change only one at a time and watch the impact. Change values by either doubling or halving. 26 | 27 | Run a test schedule. I used a schedule that switches between 200 and 250 F every 30 minutes. The kiln will likely shoot past 200. This is normal. We'll eventually get rid of most of the overshoot, but probably not all. 28 | 29 | Let's balance pid_ki first (the integral). The lower the pid_ki, the greater the impact it will have on the system. If a system is consistently low or high, the integral is used to help bring the system closer to the set point. The integral accumulates over time and has [potentially] a bigger and bigger impact. 30 | 31 | * If you have a steady state (no oscillations), but the temperature is always above the set point, increase pid_ki. 32 | * If you have a steady state (no oscillations), but the temperature is always below the set point, decrease pid_ki. 33 | * If you have an oscillation but the temperature is mostly above the setpoint, increase pid_ki. 34 | * If you have an oscillation but the temperature is mostly below the setpoint, decrease pid_ki. 35 | 36 | Let's set pid_kp next (proportional). Think of pid_kp as a dimmable light switch that turns on the heat when below the set point and turns it off when above. The brightness of the dimmable light is defined by pid_kp. Be careful reducing pid_kp too much. It can result in strange behavior. 37 | 38 | * If you have oscillations that don't stop or increase in size, reduce pid_kp 39 | * If you have too much overshoot (after adjusting pid_kd), reduce pid_kp 40 | * If you approach the set point wayyy tooo sloooowly, increase pid_kp 41 | 42 | Now set pid_kd (derivative). pid_kd makes an impact when there is a change in temperature. It's used to reduce oscillations. 43 | 44 | * If you have oscillations that take too long to settle, increase pid_kd 45 | * If you have crazy, unpredictable behavior from the controller, reduce pid_kd 46 | 47 | Expect some overshoot as the kiln reaches the set temperature the first time, but no oscillation. Any holds or ramps after that should have a smooth transition and should remain really close to the set point [1 or 2 degrees F]. 48 | 49 | ## Troubleshooting 50 | 51 | * only change one value at a time, then test it. 52 | * change values by doubling or halving 53 | -------------------------------------------------------------------------------- /docs/ziegler_tuning.md: -------------------------------------------------------------------------------- 1 | # PID Tuning Using Ziegler-Nicols 2 | 3 | This uses the Ziegler Nicols method to estimate values for the Kp/Ki/Kd PID control values. 4 | 5 | The method implemented here is taken from ["Ziegler–Nichols Tuning Method"](https://www.ias.ac.in/article/fulltext/reso/025/10/1385-1397) by Vishakha Vijay Patel 6 | 7 | One issue with Ziegler Nicols is that is a **heuristic**: it generally works quite well, but it might not be the optimal values. Further manual adjustment may be necessary. 8 | 9 | - make sure the kiln-controller is **stopped** 10 | - make sure your kiln is in the same state it will be in during a normal firing. For instance, if you use a kiln vent during normal firing, make sure it is on. 11 | - make sure the kiln is completely cool. We need to record the data starting from room temperature to correctly measure the effect of kiln/heating. 12 | 13 | ## Step 1: Stop the kiln-controller process 14 | 15 | If the kiln controller auto-starts, you'll need to stop it before tuning... 16 | 17 | ```sudo service kiln-controller stop``` 18 | 19 | After, you're done with the tuning process, just reboot and the kiln-controller will automatically restart. 20 | 21 | ## Step 2: Run the Auto-Tuner 22 | 23 | run the auto-tuner: 24 | ``` 25 | source venv/bin/activate; ./kiln-tuner.py 26 | ``` 27 | 28 | The kiln-tuner will heat your kiln to 400F. Next it will start cooling. Once the temperature goes back to 400F, the PID values are calculated and the program ends. The output will look like this: 29 | 30 | ``` 31 | stage = cooling, actual = 401.51, target = 400.00 32 | stage = cooling, actual = 401.26, target = 400.00 33 | stage = cooling, actual = 401.01, target = 400.00 34 | stage = cooling, actual = 400.77, target = 400.00 35 | stage = cooling, actual = 400.52, target = 400.00 36 | stage = cooling, actual = 400.28, target = 400.00 37 | stage = cooling, actual = 400.03, target = 400.00 38 | stage = cooling, actual = 399.78, target = 400.00 39 | pid_kp = 14.231158917317776 40 | pid_ki = 4.745613033146341 41 | pid_kd = 240.27736881914797 42 | ``` 43 | 44 | ## Step 3: Replace the PID parameters in config.py 45 | 46 | Copy & paste the pid_kp, pid_ki, and pid_kd values into config.py and restart the kiln-controller. Test out the values by firing your kiln. They may require manual adjustment. 47 | 48 | ## The values didn't work for me. 49 | 50 | The Ziegler Nicols estimate requires that your graph look similar to this: [kiln-tuner-example.png](kiln-tuner-example.png). The smooth linear part of the chart is very important. If it is too short, try increasing the target temperature (see later). The red diagonal line **must** follow the smooth part of your chart closely. 51 | 52 | ## My diagonal line isn't right 53 | 54 | You might need to adjust the line parameters to make it fit your data properly. You'll do this using previously saved data without the need to heat & cool again. 55 | 56 | ``` 57 | source venv/bin/activate;./kiln-tuner.py -c -s -d 4 58 | ``` 59 | 60 | | Parameter | Description | 61 | | --------- | ----------- | 62 | | -c | calculate only (don't heat/cool and record) | 63 | | -s | show plot (requires pyplot be installed in the virtual env) | 64 | | -d float | tangent divisor which modifies which part of the profile is used to calculate the line. Must be >= 2.0. Vary it to get a better fit. | 65 | 66 | ## Changing the target temperature 67 | 68 | By default it is 400F. You can change this as follows: 69 | 70 | ``` 71 | python kiln-tuner.py -t 500 72 | ``` 73 | -------------------------------------------------------------------------------- /docs/troubleshooting.md: -------------------------------------------------------------------------------- 1 | Troubleshooting 2 | ========== 3 | 4 | When I started this project, I'd never worked with RPi gpio.

Any board supported by [blinka](https://circuitpython.org/blinka) and has SPI should work. You'll also want to make sure the board has wifi. If you use something other than a Raspberry PI and get it to work, let me know. | 43 | | ![Image](https://github.com/jbruce12000/kiln-controller/blob/main/public/assets/images/max31855.png) | [Adafruit MAX31855](https://www.adafruit.com/product/269) or [Adafruit MAX31856](https://www.adafruit.com/product/3263) | Thermocouple breakout board | 44 | | ![Image](https://github.com/jbruce12000/kiln-controller/blob/main/public/assets/images/k-type-thermocouple.png) | [Thermocouple](https://www.auberins.com/index.php?main_page=product_info&cPath=20_3&products_id=39) | Invest in a heavy duty, ceramic thermocouple designed for kilns. Make sure the type will work with your thermocouple board. Adafruit-MAX31855 works only with K-type. Adafruit-MAX31856 is flexible and works with many types, but folks usually pick S-type. | 45 | | ![Image](https://github.com/jbruce12000/kiln-controller/blob/main/public/assets/images/breadboard.png) | Breadboard | breadboard, ribbon cable, connector for pi's gpio pins & connecting wires | 46 | | ![Image](https://github.com/jbruce12000/kiln-controller/blob/main/public/assets/images/ssr.png) | Solid State Relay | Zero crossing, make sure it can handle the max current of your kiln. Even if the kiln is 220V you can buy a single [3 Phase SSR](https://www.auberins.com/index.php?main_page=product_info&cPath=2_30&products_id=331). It's like having 3 SSRs in one. Relays this big always require a heat sink. | 47 | | ![Image](https://github.com/jbruce12000/kiln-controller/blob/main/public/assets/images/ks-1018.png) | Electric Kiln | There are many old electric kilns on the market that don't have digital controls. You can pick one up on the used market cheaply. This controller will work with 110V or 220V (pick a proper SSR). My kiln is a Skutt KS-1018. | 48 | 49 | ### Schematic 50 | 51 | The pi has three gpio pins connected to the MAX31855 chip. D0 is configured as an input and CS and CLK are outputs. The signal that controls the solid state relay starts as a gpio output which drives a transistor acting as a switch in front of it. This transistor provides 5V and plenty of current to control the ssr. Since only four gpio pins are in use, any pi can be used for this project. See the [config](https://github.com/jbruce12000/kiln-controller/blob/main/config.py) file for gpio pin configuration. 52 | 53 | My controller plugs into the wall, and the kiln plugs into the controller. 54 | 55 | **WARNING** This project involves high voltages and high currents. Please make sure that anything you build conforms to local electrical codes and aligns with industry best practices. 56 | 57 | **Note:** The GPIO configuration in this schematic does not match the defaults, check [config](https://github.com/jbruce12000/kiln-controller/blob/main/config.py) and make sure the gpio pin configuration aligns with your actual connections. 58 | 59 | ![Image](https://github.com/jbruce12000/kiln-controller/blob/main/public/assets/images/schematic.png) 60 | 61 | *Note: I tried to power my ssr directly using a gpio pin, but it did not work. My ssr required 25ma to switch and rpi's gpio could only provide 16ma. YMMV.* 62 | 63 | ## Software 64 | 65 | ### Raspberry PI OS 66 | 67 | Download [Raspberry PI OS](https://www.raspberrypi.org/software/). Use Rasberry PI Imaging tool to install the OS on an SD card. Boot the OS, open a terminal and... 68 | 69 | $ sudo apt-get update 70 | $ sudo apt-get dist-upgrade 71 | $ git clone https://github.com/jbruce12000/kiln-controller 72 | $ cd kiln-controller 73 | $ python3 -m venv venv 74 | $ source venv/bin/activate 75 | $ pip install -r requirements.txt 76 | 77 | *Note: The above steps work on ubuntu if you prefer* 78 | 79 | ### Raspberry PI deployment 80 | 81 | If you're done playing around with simulations and want to deploy the code on a Raspberry PI to control a kiln, you'll need to do this in addition to the stuff listed above: 82 | 83 | $ sudo raspi-config 84 | interfacing options -> SPI -> Select Yes to enable 85 | select reboot 86 | 87 | ## Configuration 88 | 89 | All parameters are defined in config.py. You need to read through config.py carefully to understand each setting. Here are some of the most important settings: 90 | 91 | | Variable | Default | Description | 92 | | -------- | ------- | ----------- | 93 | | sensor_time_wait | 2 seconds | It's the duty cycle for the entire system. It's set to two seconds by default which means that a decision is made every 2s about whether to turn on relay[s] and for how long. If you use mechanical relays, you may want to increase this. At 2s, my SSR switches 11,000 times in 13 hours. | 94 | | temp_scale | f | f for farenheit, c for celcius | 95 | | pid parameters | | Used to tune your kiln. See PID Tuning. | 96 | | simulate | True | Simulate a kiln. Used to test the software by new users so they can check out the features. | 97 | 98 | 99 | ## Testing 100 | 101 | After you've completed connecting all the hardware together, there are scripts to test the thermocouple and to test the output to the solid state relay. Read the scripts below and then start your testing. First, activate the virtual environment like so... 102 | 103 | $ source venv/bin/activate 104 | 105 | then test the thermocouple with: 106 | 107 | $ ./test-thermocouple.py 108 | 109 | then test the output with: 110 | 111 | $ ./test-output.py 112 | 113 | and you can use this script to examine each pin's state including input/output/voltage on your board: 114 | 115 | $ ./gpioreadall.py 116 | 117 | ## PID Tuning 118 | 119 | Run the [autotuner](https://github.com/jbruce12000/kiln-controller/blob/main/docs/ziegler_tuning.md). It will heat your kiln to 400F, pass that, and then once it cools back down to 400F, it will calculate PID values which you must copy into config.py. No tuning is perfect across a wide temperature range. Here is a [PID Tuning Guide](https://github.com/jbruce12000/kiln-controller/blob/main/docs/pid_tuning.md) if you end up having to manually tune. 120 | 121 | There is a state view that can help with tuning. It shows the P,I, and D parameters over time plus allows for a csv dump of data collected. It also shows lots of other details that might help with troubleshooting issues. Go to /state. 122 | 123 | ## Usage 124 | 125 | ### Server Startup 126 | 127 | $ source venv/bin/activate; ./kiln-controller.py 128 | 129 | ### Autostart Server onBoot 130 | If you want the server to autostart on boot, run the following command: 131 | 132 | $ /home/pi/kiln-controller/start-on-boot 133 | 134 | ### Client Access 135 | 136 | Click http://127.0.0.1:8081 for local development or the IP 137 | of your PI and the port defined in config.py (default 8081). 138 | 139 | ### Simulation 140 | 141 | In config.py, set **simulate=True**. Start the server and select a profile and click Start. Simulations run at near real time. 142 | 143 | ### Scheduling a Kiln run 144 | 145 | If you want to schedule a kiln run to start in the future. Here are [examples](https://github.com/jbruce12000/kiln-controller/blob/main/docs/scheduling.md). 146 | 147 | ### Watcher 148 | 149 | If you're busy and do not want to sit around watching the web interface for problems, there is a watcher.py script which you can run on any machine in your local network or even on the raspberry pi which will watch the kiln-controller process to make sure it is running a schedule, and staying within a pre-defined temperature range. When things go bad, it sends messages to a slack channel you define. I have alerts set on my android phone for that specific slack channel.
