[Blog] OctoPrint On Air #13 (Patreon)

OctoPrint On Air #13

The thirteenth episode of a monthly dev log/Q&A session about all things OctoPrint for my Patrons on Patreon which aired live on November 11th 2017. My Patrons can submit questions to answer during the Q&A session via a Google Form before and - usually ;) - also live during the broadcast via the chat. Expect more videos like that roughly on a monthly schedule. If you want to attend the live broadcast and ask questions beforehand or live on air, consider becoming a Patron on Patreon and selecting one of the corresponding perks - that will also help me with continuing to work on OctoPrint full time, which I love doing!

Develop plug-ins? Become the maintainer of existing plug-ins such as FirmwareUpdater? PR for new features or bug fix?" 00:35:50 "I would like to see the temperature of my Raspberry Pi 3 with other temperature (Tool, Bed). For you, what is the best approach to implement that? Building a plug-in? Based on which mixin?" 00:38:34 "In the GCode Viewer, I like to change the settings (check Zoom, show previous layer, uncheck moves and retracts). I have to so this each time. Is there a way to save these settings? I see nothing in the admin part." 00:40:41 "Have there been any further contacts from printer manufacturers wanting to jump aboard the OctoPrint bandwagon the way Aleph Objects has, since the last time you mentioned the funding hunt?" 00:44:04 "How would you feel about an open hardware manufacturer shipping kits with OctoPrint bundled onboard?" 00:45:00 "Anything that can be done to lower latency between line sends in OctoPrint or not? Kamikaze embeds Octoprint onboard the printer, so there's no physical limitation to the baud rate we can handle, but OctoPrint always takes 100ms between sending two lines. […] Any ideas whether this is something in the OctoPrint comm layer, or if it's an underlying library that's causing issues there? And what can we do about it other than trying workarounds (increased buffer sizes, slower print speeds, etc.)?" 00:58:52 "Is there a way to suppress or change the error window on the CONTROL page so that it doesn't show a big black box with the error showing where the video window is [if no webcam is connected]?"
