Klipper

Since initially setting up go2rtc on my printer’s attached Raspberry Pi running klipper I’ve been on a quest to optimise the quality of the video stream. Hardware I began by improving the physical conditions, adding a brightness-controlled LED light bar to the top of the printer’s frame right next where the webcam is mounted by connecting it to a spare screw-terminal on my mainboard. The second major physical change was the webcam itself. Initially I setup a Logitech C270 which, as far as I can tell is one of the most popular USB webcams to use due to it’s low cost and 720p resolution. For me it was the logical choice at the time as I found it in a bargain bin for the low cost of $5. ...

From when I first upgraded my 3D printer to use Octoprint in 2020 one part of the setup that has been essential has been the ability to monitor and control my printer remotely. Initially I used a seperate Raspberry Pi 3b+ with a USB webcam streaming over octoprint’s mjpeg streamer. This worked well for a while but the quality was limited to 640x480 and the frame rate was low, making it hard to see fine details of the print. ...

Recently I added an upgrade to my 3D printer that I’m really excited about as it takes advantage of quite a few different technologies that I haven’t used before. Primarily the use of CANBus and Klipper’s multi-MCU processing capabilities. In short the upgrade uses CANBus to communicate between the printer’s mainboard and the PCB placed on the tool head, drastically reducing the number of cables down from ten plus down to four, two for twelve volt power and a twisted pair of CANBus wires for data and signalling. ...

For a long time, approximately 4 years I’ve been using Ultimaker’s Cura as my primary slicer for 3D printing, although it’s heavy leaning towards use with Ultimaker’s own printers it does a good job of supporting a wide range of other printers as well. When I initially received my CR-10 it was supported out of the box and there were a couple community profiles that made it easy to get good print quality out of the box. ...
