Prusa SL1 - Magnetic Pi WiFi Camera

thingiverse

My Prusa SL1 resin printer sits quietly in the basement, a constant presence that requires frequent checks to ensure its print still clings firmly to the build plate. To avoid this tedious task, I devised a small camera system to keep watch over it. What you need is: - A Raspberry Pi Zero W paired with a micro SD card - The Kuman Camera Module attached via a ribbon cable - Four sturdy magnets measuring 20mm x 2mm in size - A Micro USB Power cable that's been carefully bent at a 90-degree angle - Electrical tape, the type that sticks well and is made of rubber - Super glue and hot glue for assembly Assemble: Once you've printed both cases, use super glue to secure the magnets inside. Make sure they're oriented correctly so they attract each other. I also glued the circuit boards and lids to their respective cases using a small amount of hot glue. Hardware: Attach the Camera and Pi to the orange glass without causing any damage to your printer – no holes or screws are necessary. The camera is positioned on the inside, while the Pi sits outside the glass. The two shells will stick together thanks to four magnets. To increase friction on the glass surface, I applied a small amount of Electrical tape to the glass-facing sides of both shells. The thin ribbon cable connecting the Pi and Camera maintains the printer's seal. You can adjust the camera's focus by rotating its lens. Software: I installed Octoprint on my Raspberry Pi Zero W. Although it isn't directly connected to the printer, this setup provides easy WiFi access and a live video feed from the camera. Visit https://octoprint.org/ for more information.
