This project was conceived because I have a resin 3D printer that I want to run outside. Because the printer is outside, I need to leave it blocked from sunlight. Therefore, I cannot check on the print by lifting the lid (at least not during the daytime).
I have added a temperature sensor to be able to monitor how hot the internals of the printer may be getting. See the developer notes below.
The majority of the code as repurposed from the motion_camera repo. Look there for more detailed documetnation.
Upon completion the unit will
- ✔ Turn on a camera on a set interval
- ✔ Turn on a camera with ad hoc command
- ✔ Turn on light(s) before recording with the camera
- ✔ Store videos on SSD to be accessed via SSH
- ✔ Record temperature in a log to be accessed via SSH
DIAGRAM NEEDED
| Pin Name | Pin Number (BCM) | Purpose |
|---|---|---|
| LIGHT_1_PIN | 6 | Lighting: Brightening the printing chamber |
| LIGHT_2_PIN | 13 | Lighting: Brightening the printing chamber |
| N/A | GND (any) | Lighting: Ground |
| 1-Wire Connection | 4 | Temperature Sensor: THIS WILL REQUIRE ADDITIONAL STEPS |
| N/A | GND (any) | Temperature Sensor: Ground |
| N/A | 5V | Temperature Sensor: Power |
PiCamera must be properly connected or program will not run.

You will need to ensure picamera2 is installed on your machine.

I have documented the setup of the camera extensively in the Motion Camera Repo. Refer to this documentation to avoid duplication of efforts.
temp.py to be tested independently before adding functionallity to main.py.
Datasheet is included in the repository.
One-Wire Interface needs to be enabled to read the data pin. Do this in the RPi config.
Documentation can be found here.
Tutorial can be found here.
- Add to /boot/config.txt
Run the raspberry pi config tool
sudo raspi-configSelect Interface Options
Select 1-Wire and Select "Yes"
- Reboot
sudo reboot- We need to add a bootable kernal to Linux:
sudo modprobe w1-gpio
sudo modprobe w1-therm- Change directories and check for attached device:
cd /sys/bus/w1/devices
ls- Enter device directory:
cd 28-XXXXXXXXXXXX- Check raw temperature readout:
cat w1_slaveAbout
The library temp.py was created using code from the tutorial referenced above.
It was adjusted so that it can be used as a library as well as run as a main function.
The above steps will need to be completed before the code can be run.
Integration
I set up the log function to take prefix= argument in order to accomodate the temp log.

10/29/24 - Process for 10/8 was essntially repeated. FEP may need replacing in the spring. I was unable to tell if it was punctured. I have added a wash bin that I printed on the K1C. Added file to
print filesdirecetory.
10/20/24 - The weather will be nice for at least a week so I'm getting the printer out.
10/8/24 - I have put the machine away for possible winter storage. I am getting ready to spend time with the family for a few weeks, and will get it out again afterward if the weather allows. Printer was disassembled and parts cleaned. The parts are in the "Resin Printer" drawer. FEP was inspected and I determined it was acceptable to store. Current known resin profiles were added to this repo.
October 2024
- Greased the motor screw
- Added magnetic build platform (after destroying the surface of the platform)
- I have noticed what I believe to be paint comming off from somewhere and making its way into the vat. Cleaning may help with this, we'll see next time it is used.

- Funnel filters
- Wash Containers - 3D print?
