It's important to remember that the MK3 series is all on 8bit controllers that don't have a lot of ram or flash space and are very slow compared to like an SKR 2 board or similar. If you want to try this with a Pi Zero or an older Raspberry Pi, you may experience unexpected print failures. It can get ridiculous performance out of an old ATmega chip. There have been reports of limited success using OctoPrint on a Raspberry Pi Zero W, but only if you have no intention of using a camera to monitor your prints. Boards and complete kits are available now In this article, we will discuss the benefits of using a camera with OctoPrint and some of the options you can choose from. Now you can DIY an alternative to the Amazon Fire TV Stick. Neil Hailey tip Can't find a Raspberry Pi Check out Orange Pi for OctoPrint. The amazing part is that it also runs on the Pi Zero W. I have a lot to do with klipper these days, it's very bare-bones compared to Prusa/marlin but uses a pi to do the motion planning and uses its own protocol to talk to the controller board for deadline stepping. Kodi is one of the best open source media server software for making a media box for your TV. If you have access to the marlin configuration you can try increasing the input buffer and planner queue and enabling advanced ok which lets the controller board acknowledge gcode lines asynchronously which improves throughput. If you have a prusa you may be stuck with what the firmware supports, but I think current prusa firmware supports meatpack (lossless) compression and arcwelder (dramatic but potentially lossy) compression if you have data rate issues. Yes, I think the default for klipper is 256k and works well between most controller boards and raspberry pi type devices, but I think you can run upto about 16M on a pi.
