BFTB design: Z axis wobble, lead screws and bearing blocks Alex Kenis 2019-03-30 | This series of videos explain the design choices, experiments, research and theory behind the design choices and trade-offs I made when designing the 'bang for the buck' live stream printer.This particular video is an overview of the lead screw arrangement for the Z-axis. I will be covering the Z-axis as a whole in a future video. Of course, this is all subjective, but I tried to include enough theory, history, and experimentation to make the video informative as well. Feel free to post your own experiences and design choices in the comments below.TIME INDEX:0:55 intro3:00 background and history7:26 theory and demonstrations17:05 Linear actuator design23:42 trade-offs and budget choices28:42 bearing types30:24 upgrades, alternatives, and future plansMy contribution links:MONTHLY SUBSCRIPTION:patreon.com/AlexKenisONE-TIME CONTRIBUTION:https://PayPal.me/AlexKenisAFFILIATE LINK:amazon.com/?tag=alexkenisonli-20Background music by my band Solamors, you can contribute by buying a copy on bandcamp.com, or iTunes, Google Play, etc etc:solamors.bandcamp.comaletheian.bandcamp.comPRODUCTS and blog:AlexKenis.com (redirects to my blog at the moment)

Stepstick jumpers: basic concepts for n00bs Alex Kenis 2019-12-01 | I was short on time this week, so I put together a video on the basic concepts surrounding those pesky stepstick microstepping jumpers for noobies and anyone that is unfamiliar with concepts like logic voltage, pull-ups, etc. I cover the fundamentals using the RAMPS board and allegro Pololu drivers as reference, but also touch on Trinamic concepts, etc. Time index is below:If you are planning to do any black friday or cyber monday shopping, please consider using my affiliate links:AFFILIATE LINK:USA amazon.com/?tag=alexkenisonli-20UK amazon.co.uk/?tag=alexkeniso03c-21Germany https://www.amazon.de/?tag=alexkenison0c-21Canada amazon.ca/?tag=alexkenisonca-20TIME INDEX:1:05 what are jumpers2:28 step stick history and basics4:40 jumper logic voltage concepts12:20 tangent: RAMPS pulldown resistor13:13 Trinamic and other drivers19:35 jumper 3 & Trinamic24:35 clones and jumper confusion26:01 on-board resistor jumpersMy contribution links:MONTHLY SUBSCRIPTION:patreon.com/AlexKenisONE-TIME CONTRIBUTION:https://PayPal.me/AlexKenisPRODUCTS and blog:AlexKenis.com (redirects to my blog at the moment)

Ender3 benchy battle: stock board vs SKR mini V1.2 Alex Kenis 2019-11-11 | Overview of installation of the newly revised SKR mini e3 v1.2... and a 'battle of the benchies' against the stock board, using the 'out of the box' firmware and same gcode for each. Not a 'deep dive' or review, but there is enough info here to be fun and a bit useful. More in-depth reviews and testing are still a few vids away, so hopefully this provides some amusement until then. As of the time of testing, tethered printing was wonky in a few programs, so I would print via SD until then.

Ender part 1: Hardware and assembly evaluation Alex Kenis 2019-09-28 | First part in the series, WOOO! This vid introduces the whole series and deals with my initial impression of the assembly process and hardware, as well as thoughts on improving the process and printer in general. Feel free to skip around using the time index if you get tired of my rambling. We'll be using the Ender series as both a how-to guide, AND as a springboard for more complex concepts. I know I skipped a few things, but the video got pretty long, so we'll address even more specifics in future vids.(On the business end: this series is ending up costing me more up-front $$ and time than I had anticipated, so I will be enabling overlay ads for the series -- which I don't usually do -- to offset the cost a bit. Sorry if that is annoying. I WON'T be enabling un-skipable ads though, because they annoy me greatly, and I wouldn't do that to you fine folks.) ALSO, for you new folks that may not know, in terms of the comments section, I have basic spam controls enabled, so some comments with links or rapid successive posts get caught in the spam folder, and I have to manually approve them... I do that as quickly as I can, but sometimes it is a day or two for me to get around to it... so don't freak out and think you are blocked. I don't typically block anyone if I can help it, UNLESS the comments are obvious spam/trolling or are vulgar/uncivil/racist/etc.TIME INDEX:0:30 Intro and explanation for new viewers1:50 Background on the series7:50 Ender 3 good points10:17 Ender 3 bad points (on my ender)10:22 checking the safety ground11:20 checking the Bowden couplers13:55 Ender 3 bad points (on all enders)14:06 Quality control rant16:30 Tangent about adjustments and construction17:50 some upcoming vids in the series18:56 other random potential future issues20:43 fan experiment tangent23:37 the XT60 connector24:36 general thoughts for the desktop printer industry31:05 TL;DR summary and closing thoughts37:43 Outro and closing statementsMy contribution links:MONTHLY SUBSCRIPTION:patreon.com/AlexKenisONE-TIME CONTRIBUTION:https://PayPal.me/AlexKenisBackground music by my band Solamors, you can contribute by buying a copy on bandcamp.com, or iTunes, Google Play, etc etc:solamors.bandcamp.comaletheian.bandcamp.comPRODUCTS and blog:AlexKenis.com (redirects to my blog at the moment)affiliate links:usaamzn.to/2LSHOq4 upgrade PSUamzn.to/31ugGnH Ender printerUKamzn.to/2LVssRH upgrade PSUamzn.to/2QhptZ9 Ender printerDEamzn.to/2MagJ1V upgrade PSUamzn.to/2UZ8bP8 Ender printerCanadaamzn.to/2Oaao95 upgrade PSUamzn.to/2LSKbcs Ender printerGeneral product links:USA amazon.com/?tag=alexkenisonli-20amzn.to/2luhMQrUK amazon.co.uk/?tag=alexkenisonli-21amzn.to/2jUoKxTGermany https://www.amazon.de/?tag=alexkenison0c-21Canada amazon.ca/?tag=alexkenisonca-20amzn.to/2luivRFOh, random tip: and if you are looking for massive storage, there are some large drives on sale at the moment (I grabbed a few)8TB @ 140 and 10 TB HDD @ $180amzn.to/2mCHqU0

Creality Ender (and others!) safety issue - chassis ground connection Alex Kenis 2019-09-16 | The safety ground is a circuit that ties a conductive chassis to earth in case the chassis becomes electrified, thus protecting the user. If you want to see if this issue effects you (ender or other): power off and unplug the power supply, then probe from the safety ground prong on the AC inlet to see if there is continuity (a few ohms or less) to the metal chassis (remember that there is a coating on it, so probe the bolt standoff as shown in the vid, or the inside of a punch-out where there is no coating).

Livestream technical difficulties Alex Kenis 2019-08-24 | The livestream ended up being 34 seconds long.... oooh boy. I'm on a 250mb connection, but the stream was getting a bad quality and time out warning on youtube. I'll reschedule when I get to the root of the issue. Sorry about that
Rant: If you say open source... open the source please Alex Kenis 2019-08-22 | It's not just a marketing buzz word. Hopefully this vid can be a resource for companies that are trying to become compliant, and companies that are 'on the fence' about it. Open source is very important to the development and continuation of the desktop 3d printing industry. So much so that it has become a marketing buzz term that is applied without even complying with it. I wanted to provide examples of how much easier open source makes life for the tech-people involved. And to make sure that the term 'open source' does not get diluted to the point that it has little meaning. As I get to various boards in the future, I will make it a point to praise the manufacturers that are making the effort and supporting the community and industry. Thank you to the good guys.(P.S. I do my best to use 'labeled for reuse' or free/open graphics and provide attribution for all the graphics I use for these vids, but some of them were a bit tough to track down, so general URLs are provided as source, as some of them were pulled from actual online discussions to use in real-world examples under fail use)My contribution links:MONTHLY SUBSCRIPTION:patreon.com/AlexKenisONE-TIME CONTRIBUTION:https://PayPal.me/AlexKenisAFFILIATE LINK:USA amazon.com/?tag=alexkenisonli-20amzn.to/2luhMQrUK amazon.co.uk/?tag=alexkenisonli-21amzn.to/2jUoKxTGermany https://www.amazon.de/?tag=alexkenison0c-21Canada amazon.ca/?tag=alexkenisonca-20amzn.to/2luivRFBackground music by my band Solamors, you can contribute by buying a copy on bandcamp.com, or iTunes, Google Play, etc etc:solamors.bandcamp.comaletheian.bandcamp.comPRODUCTS and blog:AlexKenis.com (redirects to my blog at the moment)
Ender Livestream announcement, current and upcoming subjects Alex Kenis 2019-08-15 | Announcement vid for the Ender3 build. (Quickie vid with minimal production, oh and please ignore the occasional "name" text that pops up in the corner... those were time index markers that I never filled in). The stream will be basic unboxing and assembly, with a focus on evaluation of parts and construction, as well as community Q&A, and a few test printsAmazon wish list: amazon.com/hz/wishlist/ls/3KH6NAKJP8BJKEnder-3 affiliate links from official Creality amazon storefronts:USAamzn.to/2Z5d3qvCAamzn.to/2H4IoiOUKamzn.to/2KL7YuhDEamzn.to/2yXjDAJ
Etched and oxidized stainless steel logo plate: art meets science Alex Kenis 2019-07-22 | This is a vid of the process behind making a logo plate for a project I am currently working on. This is not a how-to, but rather a glimpse of a process behind one of my current projects. Please take necessary precautions if doing any of this yourself: there are plenty of complete guides and how-tos, with relevant safety information, online. Regardless, hopefully there is enough novelty in here to be educational and amusing.My contribution links:MONTHLY SUBSCRIPTION:patreon.com/AlexKenisONE-TIME CONTRIBUTION:https://PayPal.me/AlexKenisAFFILIATE LINK:USA amazon.com/?tag=alexkenisonli-20amzn.to/2luhMQrUK amazon.co.uk/?tag=alexkenisonli-21amzn.to/2jUoKxTGermany https://www.amazon.de/?tag=alexkenisonde-21amzn.to/2jUxCDECanada amazon.ca/?tag=alexkenisonca-20amzn.to/2luivRFBackground music by my band Solamors, you can contribute by buying a copy on bandcamp.com, or iTunes, Google Play, etc etc:solamors.bandcamp.comaletheian.bandcamp.comPRODUCTS and blog:AlexKenis.com (redirects to my blog at the moment)
