OctoPrint On Air #12

The twelfth episode of a monthly dev log/Q&A session about all things OctoPrint for my Patrons on Patreon which aired live on July 22nd 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!

What's next 00:14:03 Getting 1.3.5rc1 out of the door (once it's out, please test!) 00:15:40 Overdue vacation! Q&A 00:18:27 "Is there a way to increase the number of viewable lines in the terminal window?" 00:20:16 "I've ordered a new Prusa i3Mk2S and quad-filament extruder. Will this require I write a plugin, or will existing capability handle it?" 00:24:05 "Is it normal when I print and by error I touch the home buttons the printer homes and stops printing without asking me confirmation?" 00:26:32 "I like the dark theme of Octoprint, but some the icons in plugin configuration tabs don't change, what's the best way to find how to add theme support for plugins? (i.e. redeem plugin)" 00:29:33 "Why is the extrude/retract length input box on OctoPrint's control tab a "text" type and not a "number" type? Tell me there are cool shortcuts we can put in there apart from numbers, like 10e to extrude 10mm, or 50mm extrudiomus allegro to extrude 50mm quickly!" 00:32:43 "People keep railing on Octoprint's print time estimation being bad. I don't, as I think Octoprint is simply missing information to make better estimates. Even the slicer's estimates are usually off as they don't account for warmup times and the acceleration available. Would it help the time estimation if the firmware values for acceleration etc. make it feasible to increase accuracy? I'm thinking of Redeem/Replicape, since we have a plugin to edit the firmware config from the octoprint settings panel already, we could feed the key values to hooks that will help make better estimates, for example. A separate plugin to feed the values in by hand for the folks running something else would easily feed the same values to modify them from defaults. [...] Are you still getting bothered by complaints about this or is this just over the top in your opinion?" 00:43:24 "What about a temporary fix of allowing users to define an estimate offset value, i.e. I know my warmup/cooldown usually takes 20min then I can add that." 00:44:57 "Are you still getting bothered by complaints about [print time estimation] or is [enhancing that further] just over the top in your opinion?" 00:46:28 "Have you considered data collection from users with their permission?" 00:49:15 some more details on the challenges of Print Time Estimation ;) Wrap-up
