When 3D printing, you have three options:
Today’s article will focus on the last option - using a Raspberry Pi (B+ .. performance matters) and the open-source application OctoPrint.
The recommended way is to download the OctoPi operating system image (a modified Raspbian), and load it onto an SD card. This way, everything is ready.
However, I don’t like the idea of replacing my finely tuned system with a completely new one and starting over. So, I decided to do a manual installation. It’s not complicated, and the steps are described in this guide.
We control OctoPrint through a web interface:
The program connects to the printer, you upload a G-code file, and start printing.
You can monitor the printing process, control the head, temperature, etc.
I dug up a very old webcam with a resolution of 640x480. I installed the program
[fswebcam](https://www.raspberrypi.org/documentation/usage/webcams/) and, lo and behold, the camera worked without drivers. You can set it up in OctoPrint, and it will make timelapse videos for you. I made one too (in really poor quality :)).
