Dope Tech Episode 2

<<@nefelejtselirni says : I bought my pi zero 2 today and already printed a case and a mount for my 3d printer. Thank you for your guide to make it easier to get started!>> <<@ps3customgamer says : Redo this with klipper please that content would really push schools to half there 3d print time.>> <<@mihailvormittag6211 says : 👍>> <<@sail4life says : Finally, after years of waiting, RPI zero 2w is coming back in stock for us mere mortals!>> <<@hariseldon2577 says : Anybody else reporting connection problems connecting Octoprint to a raspberry. I have a the same printer which after adding the plugin has worked smoothly for a year. I have upgraded, I know big mistake , to the latest version of Octoprint. No matter what I do I get 'No serial port connection detected etc'. I have tried to connect to the printer using a pi4, a pi3b and now by a pi zero w. All give the same error. Since there is nothing wrong with the printer, which worked fine 2 days ago, and since all the pi's are fully functional, I can only presume that Octoprint has changed some thing. Incidentally, Octoprint now reports that it never supported the pi Zero.>> <<@Klausemann66 says : I wonder if I could use this Octopi/Zero setup without a proper power cord. I could plugin the usb cable for Power in my Synology NAS, which should Provider something like 900ma. Can anyone tell me if this is enough for octopi plus 1 camera on Zero w?>> <<@Furzkampfbomber says : Considering that this SBC now costs 120+ Euro at least here in Germany, would you think that an Orange Pi 2 could be a good alternative?>> <<@TheAppleFreak says : Good video! I have a similar form factor printer that I picked up on the cheap from Micro Center a bunch of years back (the Powerspec/Wanhao Duplicator i3 Mini), and I ended up taking a bit of a different approach to you. Perhaps the biggest difference was that I made an arm that clipped onto the gantry of the printer itself and kinda swung out into a suitable camera position, running a Pi camera with a long ribbon cable over to a Pi mounted on the printer tower. The advantage over a tripod based solution would be that the camera would move upwards with the print itself, which solved the problem of the print going past the top of the frame for taller prints (a problem I had on my other printer). I also ended up retrofitting a small SK6812 LED light strip to the camera arm, which I could hook up to the Pi's GPIO pins to use for lighting and visual print status monitoring. As a final little thing, I connected the Pi to a normally open relay hooked up to the printer, so I could remotely power the printer on and off using an OctoPrint plugin (though this ended up breaking in a software update and I never bothered fixing it, heh). It's always fun seeing what people do with their own setups!>> <<@vaporjoes says : You havent talked much about 3d printing other than this particular set up. I, much like you, got into 3d printing the same way. For some reason its feel very natural going from SBC's to 3D printing. I started on the same printer you have - from there I went to a flash forge finder and now a Mignda Migician X. You should put Octopi on a standard Pi board and put that pi on the back of a display (i use sunfounder). Install OctoDash and now your Pi completely controls your printer at a touch of a button. Its very very cool.>> <<@javiers.8274 says : Love your videos! Thank you Sir. Like the optimism, cause the Benchy came up pretty ugly ;D>> <<@christopherleadholm6677 says : Hey there, fellow Christopher! ...back again! Got my first 3d printer for my birthday this past week, and I knew I HAD to come back and follow your tutorials, Christopher. Got a couple practice prints out from the memory card it came with, and now its time for something a bit more challenging! Having a camera available would sure be a handy thing to have.... I, for one, welcome the OctoPi challenge... 😊>> <<@neilthomas6042 says : Very imformative, I'm not technical and find it fascinating how you manage these demonstrations. I was thinking of buying a Raspberry Pi and wondering what uses you could use them for. A nice idea.>> <<@prebenjaeger says : I love that you use a 4:3 or 5:4 monitor :')>> <<@sobamani1244 says : perfect>> <<@stuartdavison289 says : I'm watching my printer with Octoprint now, built and set up to your instructions. It's saving me from going to the garage in the snow. I'm printing a wedge so I can screw your frame design to the printer frame with T slot fasteners pointing down as it's an enclosed coreXY printer as it's currently showing a lot of the top of the little tent it lives in.>> <<@jeraldgooch6438 says : I managed to score a Raspberry Pi Zero 2 W (maybe the last one in North America, for all I know!) and was able to get OctoPi running on it and controlling my Creality Ender 3 v2. In printing a case for the Pi Zero I was reminded of one of the most vexing things about 3D printing, which is that the filament may not come off of the spool cleanly. It will bind and may cause the print to fail. Nothing like coming in to a printer that has quite happily printed air for the last hour! I suspect that I am not alone with this. Do you know of a (hopefully) simple fix for this? By the way, as with most all of your videos, this one was well researched and well presented and much appreciated.>> <<@SB-qm5wg says : 5:52 I saw a telemetry setting in there. I wish those were off by default>> <<@williamstreck288 says : Thanks! Don't change anything. Just keep teaching us in the same excellent manner as you always have! Thanks and thanks again!!!>> <<@williamstreck288 says : Thanks!>> <<@RixtronixLAB says : Nicely explained, thanks for sharing :)>> <<@wesss9353 says : Ooh 64 bit Raspberry Pi! That's going to be an excellent video>> <<@pocketstationman6364 says : I wonder if one day it'll be possible to make a DIY CRT display at home, since we're able to print an increasing amount of things and materials. I do realise that literally printing a glass tube is probably impossible due to the nature of the materials and the required accuracy but I do hope that somehow CRT monitors can be made again. Christopher, if you have something to say about this I would love to hear it. Hope you don't mind me asking... ^^;>> <<@zhitaolyu7205 says : Get a better printer, the print quality is so bad🤣>> <<@markweaver1963 says : Another great video, well done Chris. The one thing I'm waiting for on the 3d print scene is speed. Hopefully the print times will reduce drastically, I haven't seen any sign of it yet I think the average for benchy is about 4 hours? Anyone know if or when speed times will decrease? Loved the little camera mount it's amazing what you can build.>> <<@SprocketN says : Ooo look a Raspberry Pi Zero 2W, I thought they are mythical things like unicorns! Most of the suppliers I’ve tried don’t have them in stock and those that do are asking ‘mythical’ prices for them.>> <<@SprocketN says : Ooo look a Raspberry Pi Zero 2W, I thought they are mythical things like unicorns!

Amazing setup. What has happened to Stanley the Knife?>> <<@MrSpikegee says : Thanks man, your calm voice is perfect for those technical topics>> <<@LordWillyGee says : That will be mine next items to get? A 3D printer? They so many and everyone does their things? And the octoprint /camera will come in handy sent 3D printer are slow.>> <<@qc15pvetter says : Thanks!>> <<@laupetre says : Thank you for this clip! I own a Flashforge Finder printer, that is closed source and didn't use to work with octoprint; Due to your clip, I gave it a new shot and lo-and-behold , a plugin that works has been written! Thank you and the developer of the plugin!>> <<@yurycz8933 says : +>> <<@Saka_Mulia says : The thing I really enjoy about your channel is the nostalgic feel of a late night Open University video on BBC2>> <<@AndrewJackson2000 says : I came here only for you! but this ting with raspberry is out of control...!>> <<@theconstantgardene says : My friend, Do you have any video on dual drives usb flash drive type-c that can be used in both a pc and a phone? Thanks for your kind support!>> <<@send2gl says : That was fascinating, not sure I can see a personal use for a 3d printer as yet but times change.>> <<@uksuperrascal says : Imager will not install to Ubuntu studio 18.4>> <<@Paul_VanGo says : Is it possible to have a pi controlling Android Auto? And connected wirelessly to a phone?>> <<@RamjetX says : Love your content... but holy moly that print is nozzle is either clogged or extruder skipping and under-extruding horribly....>> <<@w13rdguy says : That's about the coolest pi zero 2 video yet, and there are plenty cool ones out there! Still on the fence what my next project will be, and this one has complicated the conundrum!! 😄☘️❤️>> <<@AllensTrains says : Hi Chris. I purchased a 3D Printer last year and I still haven't got it out of the box! I intend to use it at first to make items such as lineside cabinets to go on my Hornby Trakmat Layout. Railway Modelling is a good use for a 3D printer, so maybe you should take it up? A good gauge for you to go for would be TT gauge which is 3mm to the foot. The track you need is called HOm and is made by Peco and is available from Hattons. Loads of things to 3D print and loads more videos for you to make! Thanks for uploading. See Garry Hall's layout: https://youtu.be/DMeg9-Hu3SI>> <<@ernestgalvan9037 says : Another fine video, well-presented, with great content. You showed how good the ‘OctoPrint’ software is, and how much it can help with one’s 3D printing. As usual, at the end of the video, you asked viewers to ‘Hit Like, and Subscribe’. And as usual (for 99.999% of YouTubers) not one word about the author of the software. Not one word about “Created & maintained by Gina Häußge”. Not one word about how Gina Häußge, as so many FOSS authors, depends on donations to fund her work. Yours is a powerful voice in the software/hardware space, as proven by your subscriber count. You should spare a few moments to encourage users of the software to consider donating to the authors of FOSS works, how even a dollar/euro/pound/lira can help. How if you one actually uses FOSS software to make money, they should consider a monthly/yearly donation. Again, even small amounts can help. But no, you even shut down the anonymous data that she uses to help keep track of uses/problems/etc, with a rather snide “Sorry about that”. Shame on you, Sir. Shame on you.>> <<@roomtemp6374 says : Benchy is a great old standard for dialing in your printer and slicer settings. This one looks cold and overextruded to me but it's hard to tell from the video. I don't think supports are allowed in olympic freestyle benchies either. How it fails on the overhangs is informative. But we'll let the suave presenter slide on that one since he makes nice videos and gives friendly names to sharpened tools. I'd try another about 10-15 degrees hotter and look for a setting labeled something like 'extrusion multiplier' in your slicer and set it at 90% or .9 (so it uses 10% less filament). If it looks cleaner you might check your extruder calibration. It's nice they made an upgraded pi zero that runs octoprint but they seem a little proud of pi's these days. Cheers to Chris and the channel...>> <<@aman-sood says : Can you make a video on different types of motherboard chipsets? It would really help given the current situation.>> <<@elymiranda6944 says : Hi Christopher. Do you have a link to that Zerocam?>> <<@gregorymccoy6797 says : Very nice application. I can't wait to get my hands on a raspberry pi someday soon... After the shortages get sorted.>> <<@lawrenceallwright7041 says : A rather long title for this video, but worth it. I spy the 3D printed lucky cat and the stormtrooper helmet from the previous video on your desk. What do I win?>> <<@timmooney7528 says : Great article. I've ben considering getting a budget 3d printer like the Monoprice model, and wondered if there is a ny value in using an application such as OctoPi. I now have an idea what to expect with regards to printing quality and versatility of using a Pi Zerw 2.0 for a host. Thank you!>>
