Prusa SL1 - Magnetic Pi WiFi Camera

myminifactory

My Prusa SL1 resin printer sits quietly in the basement, its print job slowly making progress, but I don't want to be tied down every hour to check if it's still sticking to the buildplate. That's why I built this simple camera system to keep an eye on things for me. What you'll need: Raspberry Pi Zero W with a micro SD card Kuman Camera Module with a ribbon cable Four strong Magnets, 20mm x 2mm in size A Micro USB Power cable, bent at a 90-degree angle Electrical tape - the sticky kind Super glue and hot glue Assemble: First, print out the two cases for the camera system. Then, use super glue to secure the Magnets inside the cases, making sure they're facing each other and will attract strongly. I also glued the circuit boards and lids to their respective cases using a small amount of hot glue. Hardware: The Camera Module and Raspberry Pi Zero W can be attached to the orange glass without damaging the printer - no holes or screws are needed. The Camera is placed on the inside, while the Pi is secured on the outside of the glass. The two shells will stick together due to the four Magnets. To increase friction between the shells and the glass, I applied a small amount of Electrical tape to the glass-facing sides. The thin ribbon cable connecting the Pi to the Camera keeps the printer seal intact. You can adjust the camera's focus by rotating the lens on the front. Software: I installed Octoprint on my Raspberry Pi Zero W. Although it's not connected directly to the printer, it provides easy WiFi access and a live video stream from the camera.
