The second channel I mentioned is this one: th-cam.com/channels/zUgJrG-w_KQexroYkJR9XQ.html
Just don't expect the same amount of polish there ;-)
We are waiting for new updates if the clone, your videos really motivated me to build one myself. Maybe using threaded rods inside the motor, like the original. But I only found 300mm, should need 320mm right?
Thomas Sanladerer What grease would you reccomend for the bearings?
i guess I'm quite randomly asking but does anyone know a good place to watch new movies online?
Can't stand livestreams, so thank you for the build notes/updates. Good to see how the printer turned out.
I'll be starting my build soon so expect some more of those kickbacks from parts purchases. Many thanks for taking the time to do this!
Keep going with all of the upgrades you mentioned. I like having it all here in one location. Stream it here and then up load it here too later. Great stuff! Thanks for sharing!
I'd keep everything on one channel and your live streams are the absolute best thing I have seen about 3D printing on TH-cam. Keep them coming.
Wow, this video feels like one of your best, Tom!
I was so pumped when you said upgrades were next, because I assumed this was going to be the last video on this topic. Looking forward to it! It's been one of my favorite topics, although I tend to skip the live stuff as I just tend to not have that kind of time available.
I just finished building my first 3D printer, and watch all your videos about it, and you did helped me a lot, now i dont have a heated bed yet either, but you know it works fine with painters tape and glue bar that we have here in argentina.
I love this series, the upgrade series would be awesome!
Been using your site guide to help me set up the i3 clone I am building. Great resource and really appreciate it.
I can't wait to see the LCD screen get put on, and especially how you migrate to the custom Prusa firmware.(and upgrade the heated bed as you mentioned) This series has been hugely beneficial to me! Thank you for putting it all together!
My vote is to stream and upload to this channel only. Following two channels is annoying for me as a subscriber.
fantastic build, I enjoyed watching, and learned a lot Thnaks Tom!
I can't wait to see you make the improvements you've mentioned. Leaving the new frame unpainted would be nice. Keep up the good work.
Thoroughly enjoyed watching this build and I have been tempted to jump in and have a go myself. But I think I am waiting for something with higher resolution. Keep up the good work.
You did a great job with this! Will try to build one myself!
This was a great series btw. I enjoyed every last one.
This series inspired me to build one as well. Thanks Tom for all the work. I would love to see Dolly get decked out with a rambo mini, lead screws and a titan aero along with the MK42 clone.
Fantastic video. i was looking forward to this. i really needed to see this video. cheers man
Stream live over there, summarize and time lapse when needed here. I don't always have time to watch every thing when you stream. Thanks for being a great TH-camr!
Great video series . I am starting my own build after this. Changing a few things like normal 8mm rods instead of those skinny 5mm sticks.
Your videos are the best 3dprinting content on youtube . And yes i would like to see more of this printer on this channel
I love this series! Please make videos with upgrades etc. I learned alot about 3d printing here.
As a complete nub I really enjoyed this build and hope you show all the modifications and improvements in just as a detailed fashion.
Thanks for providing this sort of information videos.
For the beginner it is quite nice to keep your main channel with the most quality and best videos. Many advanced (me too) will of course follow both channels anyhow ;-)
Thanks for doing these videos!
Enjoyed the video series so much I decided do do the same as I build my clone. I have ran into a lot of complications here in the US with all the metric stuff also made some rookie errors when buying parts, but still having fun with the build. Looking forward to upgrades either channel. I do like the live videos although I have to watch in sections for the most part.
Thank you so much for streaming the build, I really liked hanging out in chat and learned a lot. Including the existence of a local 3d printing meetup! I think having all the streaming on the separate channel will lead to less random people finding it and causing trouble, at the cost of smaller view- and subscriber numbers. As part of that smaller niche audience, I would appreciate the calmer climate, but it might mean less ad revenue for you as well.
Great series, helpful and entertaining at the same time, thank you so much! And I think you should keep everything on this channel, why create another one? Looking forward to the next live stream already!
Carry on showing the upgrades.
I would love to see everything you do to this printer; as a newcomer to 3d printing it is extremely helpful to see this develop and how you deal with snags that you encounter.
Tom, just finished my clone build and it didn't go as smooth as your build but in the end it was still a lot of fun. I did mention your video series a lot in my series and wanted to appoligies for butchering your name. I had my ups and downs and fried a thing or two, but in the end I sure learned a ton. Still working on getting that FIRST complete print, but in time I am sure I will get there. Thanks for the series. Cheers!
This was an amazing series! I would like to see how you repair the z wobbling on this tipe of printer.
Ditto! What he said!
You should use a flat table and just roll your threaded rods on that flat surface. Every tiny bend in the rods will show up and you can try to bend it gently into shape until the rod rolls completely flat. If you have a table with a glass plate (or even a mirror or windowglass) that probably works best as a reference surface. The other solution of course would be to just buy thicker z-guide-rods and make shure the frame/guide assembly is rock solid, so the wobble of the threaded rods can not move the extruder assembly at all.
@@ProtonOne11 Why aren't belts used instead? Seems like it would be most precise...unless the power cuts out.
I want to see everything. I don't really care where you upload it, but it sure as hell teaches me a lot!
Thanks for this awesome build. My friend and I have already ordered the parts twice (Including an original E3D V6 and the mk42 bed from indiegogo) in good faith of a nice printer!
Stay creative Tom!
I say keep going with what works, continue the upgrades and changes live.
I loved the series.. More printer DIY builds!
Hi, Tom. This series has been amazing - it's given me the confidence to begin building my own clone, though I'm making mine more like the MK2s and am also going directly with an MK42 clone, as well as lead screws for the Z Axis.
I would LOVE to see you configure your printer with your new MK42 clone so I can see how you configure the original MK2 firmware. :) That's the thing I've actually been most curious about. I'd love to see this on either of your 2 channels and I'm sure when those clones become more readily available others will want to see it as well.
Cheers!
Keep the upgrade vids here please Tom and live stream it all.
Sometimes I can't watch the streams when they go live, but I always watch the ones I miss later.
Upload all changes you do! the project is really amazing
Thank you so much thomas! Thanks to you i made my own prusa i3 mk2 clone ! And it's prints are awesomee
Tom, your videos spurred me on to build my own clone.
I have posted changes to the extruder parts to accommodate the MK8 hobbed pulley, on Thingiverse.
These parts also includes a 12mm sensor mount. My clone is a 24V version, and the results are amazing.
Just watched your video series and, as some others, I've been inspired to build my own, not going for the cheapest but cheaper than the Davinci have. using 30x30mm extruded aluminium frame for mine and slowly printing some modified parts ready for all the stuff to arrive from China. Thanks for the great videos.
great work Tom. I'm building it, but it really takes a while!
Even if the stream seems trivial, I enjoy watching them when I get a chance simply because it gives people an opportunity to ask questions they otherwise wouldn't get a chance to. Granted, a lot of those questions end up being about the Anet A8 and coreXY but still, I learned a lot of extra stuff during the assembly streams ;D
Definitely want to see the upgrades, doesn't matter to me where as long as it's recorded
I'd recommend sticking with the primary channel as I have the feeling that there's substantial interest in such content. But other than that I'd like to see tweaking this printer (even if that means investing a little more) to be the best cheap Prusa clone out there. Keep up the good work!
I see a Titan Aero in the background! Can't wait for that review.
keep the build logs coming - love this project! so curious to see what you will be able to achieve with this build in the end (already very impressed how quick you have come how far at such a low budget!)
also: when is the cheapest SLA printer build project coming? ;)
Tom. However/wherever you want to show the upgrades is up to you. But PLEASE do show it in detail like you did in the live stream. It was about 12 hours... But I learned so much - it's probably the BEST 12 hours I've ever spent on TH-cam. Thanks and keep up the great work!
Hi Tom, thanks for the video series! Got my MK2 clone built following your live streams, originally built using very janky 3d printed parts, I'm now using it to reprint the new parts and they look amazing.
For the interested ones:
- I have followed the same Z-axis as tom suggest but used stainless steel and I've got zero Z-wobble
- I got a aluminium frame from ebay, wasn't very cheap (£55) but considering I had no spare decent wood and a jigsaw ...
- I started with the 3mm bed, it works fine but the screw in the corners mess up the z-homing, I need to home X and Y then move a bit and home Z
- The MK2 marlin settings result in overextrusion, probably because of gear size, I changed the extrusion ratio to 0.9 in Slic3r
My vote would be to keep all the vids in one place. I am fine with sorting out the livestream from the other. I like that you do the livestreams, keeps it real - neat to connect with you in real time. What a great time we are living in. Your prep for the other vids, like this one, shows and is appreciated. Done a wee bit of vid myself and I know I need to move from ad hoc to scripted and produced.
I enjoy seeing the entire process because I might try doing this myself to save costs of just getting started and being that I'm mechanically inclined.
The build cost more than a CTC i3 Pro B or Tronxy P802 though. Sure those will want a few parts replaced, but at least you'll have a 3D printer which will make it easier.
I also think that this series was really educating and I definitely want to build one myself and just cannibalize my first DIY printer because that thing is just a mess.
It would be great to see how the Dolly is evolving over time so maybe you keep us posted? :)
Great videos, I defiantly would like to see the addition of the mk42 and the firmware setup. The MK42 will be a game changer for this build. I have built one of these by following along and it has turned out great.
Considering it looks like some early era Rep-Rap machine but prints a lot like the real deal is impressive. It really shows how well the machine was designed to work with really whatever you have.
I find the videos where you are building from scratch and explaining why you are doing what you are doing and how it impacts the final product far more interesting than when you are just building from a kit and following the directions exactly.
I look forward to the improvements videos, and expect you to be showing us what the problems are that you are improving and talking about what options you considered
I built one. I had never used a 3d printer before, but I now have one that seems to be giving usable prints. I only need to tweak a little bit more to get holes that are the right dimensions. But this was a lot of fun. And even though I might just purchase one if I can not tune the one I built right, it was still totally worth it.
Thanks for the update. I'll probably be looking at this channel only. But go ahead and upload straight to live.
Maybe make a preview 1 minute video on this channel explaining the next project that you will be doing live on that account as I don't want to miss out :P
Awesome wrap up.
UPGRADES!!!!!! Yay!!!! This is cheap enough that even upgrades will still result in an amazingly low cost high quality printer. This whole thing was awesome, I hope Tom wasn't shaken up by the first live chat. I can't wait to build this once the mk2 bed clone is released.
I think putting the casual stuff on a separate channel makes sense. You could have a summary video on this channel with a link to the live stream recording. Keep up the good work Tom!
Would love to see you doing any upgrade. Very informative! This channel would be good enough imo.
Love to see more of it! Stream here and upload to second channel seems logical to me.
would definitely like to see the dolly taken further.
finishing it with the lcd along with the other things you mentioned in the vid.
thanks
I would love to see the upgrades, and even more. This series has inspired me to build my own, but the electronics is where I get lost. I would like to make a prusa-esque printer with dual extrusion (seperate extruders for build material and support material) and I don't know what board i should be using and why. I would love to see some more in depth videos on electronic component choices.
"How much of the upgrades would you like to see?" I'd like to see all of them really. I haven't tried building this yet, so I don't know how difficult it is to follow the instructions via livestream videos, but I've enjoyed all of the live streams of the build so far. So my vote would be more livestreams - on here or on your new channel, no preference there.
I can confirm my previous speakers... that was an impressive series ... if you take wishes, i would be happy of a similar series with a popular delta (i´ve finished a self builded kossel mini 2020 a few days away and now working on some improvements ...) ... Good work and best wishes from Bielefeld.
interested in the whole lot of mods and upgrades, pretty interesting to hear your comments ans digressions as you go on building.
I have all the the parts and have started my own build frame cut from 18mm ply can't wait to get it all 2geather and see how it goes I would love to see updates to this platform as I would like to follow along with this soon I will have my 2nd 3d printer thanks tom
If you ever need to cut a bolt down to size thread a nut on first and it will clean up the threads when you remove it after the cut.
Tom~Excellent work. This wrap-up tipped the decision on which printer to aim for. I am confident I can build one, but it comes down to time. The printer will be a means to other ends and I need it to be working reliably sooner rather than later. This was a great exercise, love your style and very interested in seeing the upgrades and troubleshooting of this machine. Very instructive. As someone else commented, not a big fan of the livestream unedited on YT. I'd like to get to the point of the video not watch the back and forth in chat. Your attention is too divided, that is simply my opinion though, Im sure many others love them. Keep up the great work. V/R k
Great job Thomas! Very inspirational! I have watched every minute of your cheap build and am on my way to build my own version. Im glad you are going to upgrade this printer to fix the main issues, I hope to see every minute of your mods!
Noob question... Can you increase the diameter of the hole that is holding the z-axis screw at the top to help eliminate z wobble? Basically, this would allow the top of the screw to float and not touch the top mount. Or would that cause a different problem with the rotation mass of the screw drive creating a different artifact in the prints? sorry if I'm using the wrong terminology.
Any info on when (and where) will those MK42 clones be available?
Hi Tom, very good tips! Love your channel. About your questions at the end personally I belive that you should keep this channel only with the edited content, like a summary, and if someone likes to learn more can go to the other channel, its easier to find the info that we need. The thing is that the real times videos are to long to see if some of the information is useful. Really nice work, tomorrow I´ll get my first 3d printer and I will follow your advices. Thanks.
please make an updated build for this. I'd love to see a fixed version of this.
Hey tom! Ive been loving your stuff, learning loads! but in regards to your channels, i have never watched a 2 hour live video, just don't have the time, i think you should split the channels along the line of live vids. thanks and keep up the good work!
awesome. I want to see everything, cause I am learning a lot about upgrades and parts that I can change in my machine. I am also learning how to do certain things an why do it this way... otherwise I wouldn't have the time or the money to do so many changes and tests.
thank you Very much Tom. This is becoming my favorite series from your channel.
I would love to see how you upgrade this printer, if you do it here, or on another channel. Keep up the great work! :)
Keep it here!
Hey Thomas, love your video's and the build of this printer was awesome. A link where I could get the clone heated bed would be highly apreciated if you could provide.
Thanks in advance.
Great idea having a live channel and keep this one for more polished and edited stuff. Like you could do the live feeds on the dolly on the other channel and then maybe stick up an edited highlight reel here!
Thanks and keep it up mate! Great videos!!!
+gilbertotron everyone keeps asking about edited-down livestreams, but the reality is that it's probably more work than a regular video and gets me a worse result.
Thomas Sanladerer that's a fair point. And there is a lot of footage to wade through too I guess. Thanks for getting back to be on it.
G'day tom. I'm in process of building the dolly printer. Thanks for your great work on this. I would love to see the completion of this. Ie the LCD etc. however another item I would love to see it to make it dual extruder. I recon that would be really cool. Either a second extruder or even better a y Bowden solution.
I really liked that series. Another suggestion: "Pimp your MK2(S)". There are so many upgrades now - it's hard to keep track of the useful ones. Or apply them on both - the Dolly and the Prusa.
As long as the videos will be featured in the build playlist on your main channel, I don't think it matters. But on this channel will be great.
Hi Tom,
I found this series to be very helpful, as I do almost all of your content. Thanks for the effort!
Also, I have a suggestion for an additional video in the series: fire safety upgrades. For this, or any cheap printer, the lower-end parts make one wonder if it wouldn't be wise to add another layer of hardware safety precautions, in case one or more components fail.
Perhaps you could start with a discussion of the safety upgrade options, from minimal to overkill. For example, does it, in your opinion, make sense to add thermal cutoffs and/or fuses to components like the heatbed, the heatbed SSR/MOSFET heatsink, the extruder, the controller board(s), the motors, the power supply, etc.
After discussing the options, seeing some implementations would be great. I haven't found much detailed content concerning 3D printer safety upgrades. Such content might make a great followup to the series. ...Just a thought. ;)
I would love to see you optimizing the firmware on the ramps to get to a decently similar level as the Mk2. I just finished building a Hypercube, while also having a Mk2 and I have not been able to get much practical usefulness out of the stock Marlin LCD interface, while the Mk2 one is amazingly configurated. Thanks for doing a great job!
Hi Tom! I'd like to see the bed upgrade video. Thank you!
This is a great and informative video. How about doing a video on building the absolute best 3-D printer that can be built for under $1000?
Keep it all in the one place. I don't want to have a another place to look for things related to this build - your website and 1 channel is enough.
*series not complete*
Hey Tom! Love this series! Saw the first two where you list all the part and was hooked. I decided to build my second printer along with this build instead of buying another one. Made some different choices along the way, had some scrap 6 mm alum diamond plate for the frame, used the z couplers. All went real well.
As far as where should you put the other content for this clone? PLEASE put it here as up load at least. Right next to these in the playlist.
I couldnt follow live so have been building with these videos sense you put out the last one and just finished tonight I ordered the LCD screan (large one) because you said it would be included and you would even do two firmwares for the two dif sizes. The LCD and SD card slot are kinda deal breakers for me because I have no computer to keep attached to it while it prints.
PS you may remember me tipping at the end of the last stream :) 3.75* stepper motors
again love it Tom, thanks
Dear Thomas. I would love to see you do a detailed side by side comparison video on the creality cr-10 and the prusa i3 mk2. Showing the quality of prints, level of detail and repeatability.
Thanks
I bought a scrap of Corian countertop and cut the frame out of that. $15 and I got a beautiful rigid frame. I also used 8mm Acme threaded rod instead of the 5mm.
Absolutely awesome learning and entertaining series. Thank you very much. I would like the source for the MK42 and see its installation as well as the upgrade to the screen and Prusa marlin build. I am changing over a Wanhao duplicator to all of the Prusa MK2S parts intermixed with the sensor and bed leveling you did on this one for a fun project. How much fiddling did you have to do to get the MK8 extruder drive gear working? Better to exacto the holes or redesign the SCAD file to the left 1mm? Any thoughts would be appreciated.
Awesome series!
So here is my question for you Tom: How did this end???
Thanks for sharing
you could use a voltage boost convertor to boost the voltage for the heated bed
i would love to see another one of these builds for 2020.. maybe an XY design? (but perhaps with some suggestions for not so dirt cheap options lol) they are very interesting and i think i will have a go at this one soon. thanks for the video :)
Instead of the tube. Print out a coupling. Use threaded end on one side and smooth down the other. Make a slot in both to be compressed by a zip tie around them. I forgot what the size of the rod and motor shaft were. I could print you two when I get my Prusa this week.
A video about the custom Prusa firmware would be great! Things like how it differs from the standard firmware (what makes it better), if it is possible to use it with RAMPS (or other boards) and how to configure it...
id also like to see more of the prusa diy clone and 3d print the wooden parts
Where to stream, well I'm following both so up to you. Awesome Stuff! Thanks for the update. I only have the frame at this point, waiting on parts. I used a 6.3mm aluminum sheet for the frame. I was thinking on upgrading to the an original E3D hot end. I have a couple of questions, 1. Z-Rods should I go to real rods or 5mm as long as they're straight will it make a big difference? 2. Heat Bed, I have 3mm & 6.3mm aluminum so I could just get a heater mat or would a 3mm circuit board be better? what would work best?
Want to see it all Tom... the only way we can learn is from success and failure.
More or less finished my build along your videos - I only started with 3D printing 2 month ago and don't have a lot of experience with electronics projects, so the videos were really helpul!
I would be interested in a debugging video, if you ever get around to it. I was really lucky and only had one defective stepper driver arrive, but if the RAMPs or Arduino would have been broken in the way yours were, I probably would have had a hard time finding out. So understanding how you diagnosed that, might help some people.
Just a note: Your Marlin firmware seems to be the stable build, however with the RCBugFix config file. Most things work with that, however my LCD gave me alot of headache. If you use the RCBugFix Marlin version with your config file slightly adapted, everything is fine.
