Very fair! Already working on a lot of this👍🏻
Awesome work, Naomi! 👍👍👍
To fix belt track, add two color lines the length of the belt, with matching marks on the front plate. Run the belt for a revolution, easy to spot alignment issues.
Instead of the tiny hex screws for belt tensioning on the front can we get knobs like the bed leveling ones on newer Enders please.
I wonder if it is possible to add some ball bearing guides that ride on the edge of the belt to keep the belt perfectly centered so it can't pull over to either side?
Other than that, and a little hairspray from time to time, it seems like a great printer, especially for people that run print farms making hundreds of the same items to be sold.
Hi
Naomi 'SexyCyborg' Wu, that's nice to know, I can't wait until this available again, as no more left on Kickstarter, 👍
Aka "The Never-Ender"!
Ha! Genius 😝
NO
YES
Awesome!

Thanks for mentioning all other printers at the beginning. Nice review.
great informative video, good to see how the 3d print community work together to try and improve the experience for everyone
I'm so happy so much work has gone into this printer and it's come this far. I can't wait to see what it's like on release
Good news is I did back this on Kick Starter and I am looking forward to getting mine in May. I started my 3D world on Dec 2, 2020 as a result of this kickstarter and I have since purchased 4 creality printers to get me started. Over 15,000 grams later I have gain some printing experience that will lend itself to the CR30. Great video and thank you for creating it, sincerely, RM3D Creations
Thanks for your awesome review on this printer Micheal. Most appreciative of the octoprint info. I didn't know it can do that.
Thanks for all the great words. Happy to help.
Thank you very much for all of your help. It would have been a very different video without you.
brilliant review from a brilliant man. not a printer for me at all but I can see its uses.
Nice video as always, Michael. That does look like a cool machine indeed.
I'm thinking I'll wait until I really need one. Hopefully that'll be a few generations from now and more of the bugs will be worked out.
I love the idea of this printer, and would love to get one, but I don't have a need for continuous prints so I can't justify the cost of backing. If things change in the future then I'll be willing to pay the increased cost. Thank you for reviewing this printer; I've been following it since Ms. Wu did a video on it a few months back and mentioned bringing it to kickstarter. I love watching your videos and your tips have really helped me improve my Ender3 pro.
You're make awesome job reviewing and explaining, respect 👌🏼
Very useful. I have backed the project but was hedging my bets, watching all reviews so that I could release my pledge before the campaign closes if I didn't like what the community was saying. Your no-punches-pulled approach gives me a good idea about what I am letting myself in for and, together with my trust in Naomi and the other important contributors involved I will be maintaining my pledge, while being under no illusions that it will be all plain sailing.
When I did my master sword I removed the blade in blender, extended the end back into the hilt, boolean'd it out, then printed the blade on the CR-30 and the hild/handle/pommel as one pied on the CR10S Pro. It came out great, and I think this is the best example I have of him saying that it's a great supplement.
Thanks for your thoroughness and transparency. I'm not looking for a belt printer now, but I was curious about how one could be managed at home.
This idea...Its a great one for those that do alot of things such as cosplay props or continuous production of smaller parts..but the quality just isnt for small stuff yet. I see they are constantly working on it to make it better, which says alot for the company, Naomi and what this can become. I personally cant afford one or cant see a personal use for it. But I wish them all the best! Great video with a fair assessment!
What a beautiful reflection at 4:32.
I’ll be passing on the CR30. Risk v’s reward to high at the moment. In a few years, once slicers are improved might be worth another look.
Experimental belt printer support just went live in Kiri:Moto 2.4. It's somewhat difficult to test without a printer in-hand. I would really appreciate your feedback on the implementation. You can run Kiri:Moto in your browser at (( grid.space/kiri/ )) and a quick video about how to use the feature is here (( czcams.com/video/0QtZzROdeyU/video.html ))
Uh, ideamaker just showed a preview of 45 degree angle printing. Karl of the white knight has some incredible profiles of blackbelt Cura. And rumor is Prusa is looking into supporting it like the other creality machines.
I've had my Cr-30 for about a week. I learned how to tram this sort of belt printer and it's been printing very well! I'm looking forward to having Octoprint running on it.
hey are you there ? I just got cr-30 there are questions I need to ask
@@TonyStark-po9di What's up?
@@JasonLooseArrowAlso i cant communicate with mine over serial, did you find anything you needed to change for the serial? And which firmware version does you printer have?
@@dead_engineer I always just used the USB cable. I sold my machine a while back. Good machine, though. It just didn't do what I needed it to do as well as my other machines.
@JasonLooseArrowAlso thank you for your reply, in the end I got it working with octoprint :)
Hey man, it would be a really good idea if you make a video about smoothening the bottom surface of an object which is being supported. So the rough surfaces caused by supports. Love the content!
It's a great product, as you said, it shouldn't be your only printer, but with a bit of tweaking, hopefully, some of it done factory side, (and slicer settings) this has the potential to be a VERY good printer for infinite length products, or doing a big batch of prints that would otherwise have you removing them on a scheduled timeframe.
Thanks michael.
I was trying to find information on the hotend, I appreciate you letting us know it's an ender 3 style MK8.
A year and a half ago when i started into the hobby, i started to build a Piper (EMT Conduit) printer and that was the first time i saw the 'piper infinity' which is a belt 3d printer. I'm sure it was inspired by one of the other originators you listed here but i always get a little sad that it is never mentioned in any of these lists of other belt 3d printers.
_Interesting machine_ ! Hope to try one in the future 😎
Dear Michael, I am happy you have reported issues not reported by other youtubers on this nice but tricky 3D printer. Thank you for your time.
We ordered it and understand the good and bad. Already have 8 active printers in our lab with an additional 4 down for repairs. The information you gave was extremely useful, and we thank you. We are eager to get ours.
This printer is so cool! I really want one but I’m still struggling to get my head round an Ender 3 pro...
Good device to print chocolate right from conveyor belt into the box. High risk to spoil big prints, but for numerous little - it's ok.
Thank you for interesting review!
Hi, Teaching Tech, I love your videos!
I've been trying to do some research, but do you have a video, or will you make one on different brands of hot ends and make a recommendation on your favorite for different jobs/filament types?
I saw the one you made for the swiss hot end, but I'd be interested on your take for the best hobbyist hot end for PLA.
Great review of it!
I really like the idea of it and considered building one of the squires until I saw the total on the BOM. I have a half dozen Creality printers and I really would have considered this if It had come out before the 6SE. I supported that Kick starter and that turned into a cluster. Mine was doing all sorts of strange things until a recent Firmware update and I'm one of the lucky ones. On the Print mill I would be worried about belt life and adhesion. I really want to see some long term testing.
Thanks! I consider this to a pre-production printer allready in production. I'll skeep this and wait for version 2 or 3 :-)
Hey Michael a video on Octoprint would be great. I assume it requires some special settings to add the cr30. Also octolapse as far as I know would require a bit of setup for the belt printer. Both would be great videos. Please also post the webcam mount you got and the cura profile you used.
Great video and perspectives. I don't have a compelling reason to obtain one now (wish I did) so I'll be a spectator.
I love this printer because its moving forward and is definitely going to make these printers better
Have you ever looked at a Voron? The community is getting larger and may be worth a look. The switchwire with nonplanar might be a really interesting project. The switchwire uses a corexy belt but for y and z.
Another benefit: It will also print non-planar, in a way. At least non-planar with respect to the bed. For example (infinitely long) aerofoil should be very easy to make.
until the printed part starts weighing more than the part being printed... then gravity will stop the print :p
I was surprrised I was not subcribed to you because I watcha lot of your videos! subbed now!
I wish they made a belt printer without the 45 degree angle. Obviously it wouldn’t be meant for really long prints but if the belt moves back and forth, it can print small objects at the normal 90 degrees. It gives the benefit of popping the print off when it’s done and allows for multiple prints to continuously made.
It's a neat design and will revolutionize large printing for things like cosplay armor and weapons. I can also see valid uses for it in the small to medium batch production space for simple objects like face shield frames or small life quality items that can be printed infinitely (until the filament spool runs out). I think it's limiting factors, however, are the possible materials that are printable. It'll print PLA all day without much of an issue, but I don't see ABS or PETG working too well, for example. That sounds like a warping and curling nightmare for sure. Who knows, though. If they get popular enough, someone will probably come up with a new filament specifically for use with these belt printers. Also, it seems like there is a lot of calibration nuance to the moving belt, so there is a lot of testing and tuning to be done to get a usable machine. That being said, I definitely think that there is a place for this machine in your arsenal if those specific conditions are met. Will I purchase one? Probably not in the near term, since I don't have a need for it, but it's great to know that it exists. There are a lot of Creality haters out there who will doubt this setup, but I think you gave it a fair assessment and I trust your analysis.
I've tried using PETG and your not exaggerating on the curling nightmare, but some seem to have no issue printing with it. Not sure what my problem is.
5:32 why this locking nob never made to any of their other printers? I'm sure it would helped a ton at retaining level on one without ABL sensor
Idk, seems like a good idea.
However, on my Ender 3 Pro, I installed a glass bed with solid permanent bed mounts, the 32bit silent motherboard, and a BLtouch auto bed leveling probe.
It's so nice.
I never have to touch the bed. Lol
I know! The never ending bed tuning could end with a simple locking knob! After months of going crazy I did this with my old XYZ’s and it transformed them! (M3 brass coupling nuts 40mm long.)
Great information Michael, I have backed this so I am going to need as much information/help as I can get! It just looks amazing though
it feels like this printer is pretty good, but its the slicer and other software that still needs a lot of versions before this can propperly print. good stuff, looks interesting for continue manufacturing.
I have no use for the thing and don't think much of the quality of the results either. However it did occur to me you could tilt the bed (actually the whole printer base) to, say, 45deg and the overhang issues would go away. You could still get usefully long prints with the printer sat at normal desk height (your sword for example) and also still able to return it to its usual orientation for the stupidly long prints (which if you're honest you're not going to want anyway...)
One of the review videos tried this. Gravity seems to only play a small part
That's a nice idea.
What a cool Idea
Thanks for the video! What are the RPI case and the camera holder models in 13:43 ? Thanks
Nice printer. When I got one, I'll do the following upgrades:
- Linear rails.
- Microswiss Hotend or Hemera extruder.
- Duet mainboard.
I’d recommend a mosquito hotend. One handed nozzle changes make things so much easier.
@@NAK3DDesigns I would go to a Dragon hotend. Also capable of one hand nozzle changes at half the price.
@@vinnycordeiro I can’t support the Dragon. It looks to be an unauthorized copy of the Mosquito which is patented technology. But that’s my personal choice.
@@NAK3DDesigns Respect your opinion, although I disagree: I don't think just adding four metallic posts between a heatblock and a heatsink could be characterized as an unathorized copy. Anyway, I'm not a lawyer, and that question is way beyond my knowledge, I may be wrong.
On the other hand, if you look at the Spider hotend, *that* is an unauthorized copy of the Mosquito.
great review, thanx for a lot of info. but how about flexible material?
Brilliant video, my first printer was a the Delta Kossel (mega pain).. 2nd Printer, Anycubic Mega S (really easy).. I need long though to make some TPU belts and gaskets.. fingers crossed 😁 I've just been thwarted by a 'stray' caphead, that I think was meant for y axis adjustment, it lodged in the extrusion behind the extruder.. kinda makes assembly difficult, so I'd definitely recommend checking all extrusion gaps for FOD..
Thanks for these videos. Can you please make some recommendations for 3D printers with larger build sizes, for example 20-25 inches in one dimension?
Hi Michael, what about making a video on what mods have to be done to a printer to print filaments that need 280-300°C? I have a cr-10 that I love, but I would like to use filaments that need higher nozzle temperature.
1:06 Best part of the video. Made me spit my drink!! LOL
Would adding a second heater at a lower temperature after the first help with adhesion and allow a more gradual cooling so parts are less likely to dislodge?
Wow, this is SOOO interesting
I think I'll do the 4 ft bed conversion for an Ender 3.
Tested and inexpensive conversion.
I'm curious, how exactly is Naomi involved in this product? Was the conveyer belt her idea, or did she contribute to the engineering or something? I've heard in 5 videos now "Naomis printer" but none seem to explain how she is involved.
Hey, thanks for the great video! Would you be able/willing to share your slicing profile? I've tried some for idea maker but they all start printing on the very top of the y axis mid air and I've tried playing around with my Cura profile but I am not getting there :(
Hey, What is the "pitting" at 13:16 in the sample using the 0.4mm layer height. I have started to get that that weird pitting using a silk gold pla. I thought about overtemp, retraction speed, coasting, infill patterns, etc I can't figure out how to get it to stop.
Would it be better if the entire device was angled at 45 degrees so the extruder points parallel to the gravity vector but still can print continuously?
I wonder if a PEI sheet would be flexible enough to work on the belt. The repeated flexing might be an issue though.
Hi i am here from the future(June 2021).. we backed the project and have gotten the printer.
I have to say it's a really good printer.
One thing that stand out, is the overall quality/price ratio..superp
I agree with the learning curve.
But ones you get more experience and also get more video on tube you will also overcome this.
You also overcome this
But i want to add a small remark.
If you are to make long print.the spool holder that is supplied with the printer is just to little.
You would want to have a big spool of filement..i made my own easy.
But i do recommend people to buy a solution or at least make one..as changing filement mid print. Introduced unnecessary challenges.
One thing that really stands out..it's very silenced..
Well we need more in depth setting vids on this....here mid June...
So please make some.
For sake of consistence with the belt level I assume there is a flat work surface under the belt that is adjustable. I am a 3d printer junky and I am planning the pick one of these up. What I am concerned with is a reusable surface. I would guess the belt is a pain to change. Can it be coated with tape? Is there a bar or anything that holds the belt down just prior to the extruder area. Would think a spring tension bread roller just before the extruder would be needed. Thank you for the review.
This has nothing to do with this review but would recommend replacing 6mm timing belt with steel or fiberglass or Kevlar core Belt. Like you channel. Appreciate what you do.
should have read would you. Thanks again
Wondering if I'm ever going to get mine I bought in the kickstarter.
I'd be interested to know more about Naomi's involvement in the product itself, rather than the marketing of it... Nothing against her at all, but Creality has been a sponsor of her. Any official job would likely be within the marketing department. This all seems quite transparent, but of course does not take away from the product. Creality seem to be on a fast-track to overtake Tiertime as China's top 3D printer manufacture, regardless. All the best to them - it would be a smart investment to stamp their machines with and merge Naomi's branding into their official product line.
China is an environmentalists nightmare. They ruin the 3d printer market with mediocre products, no innovation and only stamped Naomi on this for sexual marketing. If I want a belt printer I'll insert a belt into my folgertech. That kind of add-on is innovative and would be cheaper for anyone with a 3d printer already.
should i back this or order a prusa?
I currently have a form 3, but want to start doing small production runs of product cases.
Im interest in this for its continious printing capability, but would rather have a printer that is more reliable, better quality, and is capable of more types of geometry.
I had thought about this idea but complexities arise as any conveyor belt system has to have some flexibility. 3D Printers rely on the solid hard surface to be able to maintain the leveling. If the conveyor is to tight to compensate for any flexibility in the print bed then the conveyor would have a hard time moving. Adjust it more loosely and then the problem is flexibility making the bed have unleveled surface. BUT, interesting concept. I hesitate to buy dual extrusion printers, multi-purpose 3D Printers and ones with this conveyor. In fact I prefer Lead Screws vs. Bowden systems. Now if I needed to print multiple parts in an assembly line type of setting then this could be attractive. My favorite printer is a Lulzbot TAZ 6, which I even built the toolhead, they call it a toolhead, that has the MOARstruder Tool Head for 1.2 nozzles. GREAT for a very VERY quick prototype. Then I go back to the .4 nozzle with the 2.85mm filament. BUT, if I want to use 1.75mm filament I did built a 3rd toolhead to swap to 1.75 filament. The worst printer I own is a Sindoh DP100. There is a design flaw that, perhaps, the other enclosed 3D Printers have. The closed casing is a good idea for ABS prints but the Sindoh is very over engineered with the cassette box that holds proprietary filament, which you can get firmware to bypass that. But any extruder jam and you are opening the machine, which is a real pain. Design flaw is that the heated bed goes up and down on the Z axis. The design flaw is that the support for the bed on the rails is in the back, therefore supported by the plastic guides on the bed support in only 2 areas, the 2 back rails. Eventually the plastic guides that ride the rail on the bed support they wear out and the round structure on the bed support becomes oblong. The Lulzbot, best machine I have, you can actually print out most replacement parts, that's how I built my other 2 Lulzbot toolhead. Try to get that part, they don't sell it. And then you have to get into the major disassembly even if you had the part. Now I did break my rule of not buying multipurpose machines and I have a Snapmaker 2.0. It is pretty decent. I use it mostly for 3D Printing as I did not buy the Laser or CNC modules. One crazy printer I have is a Dobot MOOZ 2, that Naomi did a review on. She did not like it BUT she did not either have the patience or knowledge to use it. I got to say that it is my very best printer but as small as the Snapmaker original. In fact one of the 2 companies must have sued the other as they were nearly identical. Only reason I don't say that the Dobot is as good as the Lulzbot is due to the small print volume. But I printed 2 of the models that check print quality and tolerances and, guess what, the Dobot was the best. Surprised right. My Dobot does have the 3 modules, Laser, CNC and 3D Printing. I have used the CNC and Laser but not often. I've got to say, hands down, that for small models the Dobot does the absolute best builds. I do mostly robotic with Arduino and Raspberry so the parts I need are usually larger and I prefer to not glue parts together, but for smaller gears I constantly use the Dobot.
Hey Michael, Thank you for reviewing this printer! I am interested in backing this one...
only issue I have, even before watching the video, is the longevity and lifespan of the belt.
unlike a glass bed... these things will be harder and more expensive to replace. also harder to FIND the actual special belt.
the rest? awesome machine...
Just looked up Naomi Wu, she has some serious knockers... and brains.. just wow
Lotta good tips and tricks
I am curious about how it handles other materials such as petg or nylon(and how to enclose it)
I really love the idea, but for what I would need it for I wouldn't get far with PLA.
same, not sue how the belt would go though with higher bed temps needed, maybe better to just build a really long custom voron
Thx, I have a lot to think about :)
How does the mill handle 100% infill parts? Does the adhesion suffer on the belt surface?
What print speeds did you use with the larger 0.8mm nozzle and 0.4mm layer height? I just got this printer and it was painfully slow with the 0.4mm nozzle so looking to improve overall speed. thanks
After backing the CR-6 and the stuffing around there I don't think I'll ever back anything from creality ever again sorry to say.
Would you care to elaborate? Curious because I might back this one but haven't backed anything from Creality before.
Also curious to hear you elaborate. I thought the cr-6 looked solid. I was baffled why creality would kick start a machine that they should have just made to begin with.
I have the same feeling cr6 is a good printer but the the Kickstarter versions had so many trouble and an extremely bad customer service. It made the cr6 community furious. Mine luckily only had a broken power switch compared to others with burning motherboards and after many months still no replacement parts......
Hey I just got my printer! You think you can post the cura profile karl used?
i set my ender 3 up to print stuff 1 at a time. it means i cant print as many things on my build plate but it ensures that if 1 print fails its not going to be a total loss (unless that failed print was the first one)
You could fit it with a sprayer system that periodically self-sprays the belt with hairspray.
Thank you. Since I've just started with 3d printing this year, i guess ill wait a while, before trying this monster of a printer.
Thanks Michael and we'll done Naomi.
My humble advice to you is to stick with traditional Cartesian plane FDM printing, learn as much as you can, watch as many videos from Michael, Naomi, Thomas, Joel, Stephan and others as you can, learn everything you can about your specific machine, do some upgrades, learn your slicer inside and out and print as much as you can with different materials. Then, when you're looking for another challenge, maybe look at one of these. It's been 6 years for me and 5 printers later (4 FDMs, 1 Resin) and I'm still learning new stuff every time I print something. Stick with it and you'll certainly get there. Happy printing!
You missed the 2017 Stratasys H2000 infinite FDM printer. Though it lays layers completely sideways, not at an angle.
Do they make conveyor belt printers without the 45 degree angle on it?
Granted I wouldn't be able to print long parts, which I'm completely fine with, but the automation of part removal from the belt has me very intrigued.
Recently I started a project that required me to print 32 sets of chess pieces. Now, I never print more than 1 thing on the printer unless it's super tiny, which these weren't. I had to print 512 pawns individually to get them the way I wanted them.
Having a conveyor belt would have been extremely handy because I could have just told the printer to print out 512 of them one at a time and have them fall off the belt into a bin.
I don't see why this couldn't be to an Ender3 (or any I3 printer), it would be just a matter of substituting the hole y-carriage and support assembly with the belt assembly, then modifying the end gcode to roll until full release of the printed part and start again.
Tbh I do think this would be absurdly expensive with even a slimmer market than the cr-30, said that I do think it should be feasible
Shouldn't require any major changes in marlin or anything, since technically speaking the Y is still doing the same job as in a cartesian kinematics.
Said that, I probably wouldn't trust the Y carriage to have such a great precision if being substituted by a belt (given the way bigger inertia from by moving mass). I guess a CoreXY with Z moving the XY gantry (instead of the plate) would be more reliable dimensionally but the whole thing would be a huge mess and require some seriously buff hardware to run (considering the shear number of steppers required)
Finally, check out Make Anything here on CZcams, some time ago he came up with a pretty smart way of removing parts from the built plate in a I3 printer, he made a whole video about it (not very elegant solution, imho, but I can't deny the functionality of it)
Hoped I helped, have a great day ✌️
I didn't understand... ANY of that... And that's the problem. Not all of us are smart enough to do... whatever it was you just said. I'd rather just buy a working version of it.
@@The_Nonchalant_Shallot sorry mate, didn't mean to make you feel stupid... I just tried to help (and got carried away as always)
I'm not blaming you at all. I AM dumb lol
czcams.com/video/pvlzVv26Guw/video.html
Something like this lol
what about the belt / bed
is it heated?
i havent seen anyone talk about that
What webcam mount is that? I can't tell if it's 3d printed or not.
Hello Michael! Need some help! I'm looking for a way to accurately adjust the steps/mm for dimensional accuracy on my CR-30. Unfortunately, all usual calculators are designed for a 90 degree cartesian printer. Being the Y and Z axis are NOT on a 90 degree orientation, the changes in steps/mm are not the same. Do you know of a calculator or a formula that will accurately translate the 45 degree angle? Thanks in advance!
Just out of curiosity, why is the belt not made out of a thin spring steel? Wouldn't that give a better finish on the bottom and be more precise? Also what's your estimation as to the life of the belt?
From my experience spring steel is much more costly. It is far less forgiving if the nozzle makes contact, and typically still needs to be laminated with something. I think this is a good inexpensive alternative and I’m sure we will see more aftermarket options become available soon.
@@NAK3DDesigns Spring steel belt material itself is actually quite inexpensive, making a continuous belt with a smooth seam and/or laminating is much more expensive. Also the edges of the steel belt are very sharp, a consumer version would have to protect or it would be a liability concern.
@@drbtk You are 100% correct, however having it precision cut, the edges rolled to make them safe and welding the seam, that makes it very expensive... 😉
"It's just not as sticky as a traditional bed" XD XD XD
I'm very tempted to back it, trying to print long objects is a pain on my ender 3
Ive seen two different siza filiments a 1.7 and a 2.8 i believe. can both be used on these creality machines?
Does the bed still flake off on the prints or was this problem solved?
I believe they solved this issue on this newer belt.
The belt has the pattern of the print behind but I can't see any degradation of the surface.
I wonder if it would be better if it used a shallower angle, say 25 deg off vertical. Then standard parts wouldn't have such extreme overhangs etc, however, could still move indefinitely. Maybe I haven't thought it through properly though.
What filament did he use at 6:45?
I definitely wouldn't consider one of these until it is open source, but a need idea nonetheless. I know that there's been some development on the side to modify the prusa bear into a belt printer, so if that ever comes to fruition I might try that. Hopefully this goes a ways to push the development slicer side at least.
It's based on Nak 3D's (Karl's) worrk White Knight, it's already open source. The Creality version, using their inhouse tech but based on Nak 3D's design, might be proprietary unless they get $5M on KS. So never lol.
@@shamusobi2748 That just annoys me even more frankly. Making Open-Source a selling point is so counter to the spirit of the concept that it kind of just negates it. I'm still annoyed at Prusa pulling some of the same kind of stuff (appendix and failure to quickly release documentation after release of the product).
@@syber-space Not sure about how the spirit applies to forr profit companies lol. I have zero expectation that any company that pays employees and want to stay in business would ever make anything open source. But the fact that a hardware company says "if a product brings in a certain amount of profit, that's enough for us" is a BIG deal, I think.
I mean ask yourself, when was the last time you bought a original arduino from Italy for $40? That is a rare company that said "we dont need to profit of the same board for 20 years, a certain amount is enough beforre we innovate." And to me that's very fair.
Creality is being very fair with getting enough money to open source THEIR inhouse tech and innovation applied to the Nak 3D design, so the fact they even considered it is freaking amazing to me. But again it was only due to Naomi pushing hard for it. Creality asked the community for a lot, $5M. The community said no. Now let's see what Creality does. I dont expect they will open source it, but the fact that they did is more than I expected.
@@shamusobi2748 I actually bought a real Italian Arduino around a week back, but I'm a weird one in that I'm sure. Since I teach (my profit is not attached to production) I prioritize and support open-source as much as I can and open-source what I make. Most people probably don't intentionally select for open-source when buying though, so I can see why Creality wouldn't be embracing it. I think you can definitely run a business using open-source, but you have to build a community and provide good customer service/support with it, so not many do. Even Prusa is borderline closed-source at times despite being one of the better examples in the printer market. On their scale, and with their competitors, open-source probably isn't an option sadly I guess. I've never bought their products myself though (favoring more local or open products instead), so if there are enough out there like me there might be a chance at it being possible long-term... who knows?
@@syber-space curious...how much did you pay for the arduino?
Yea it's nice to be an employee, especially of an educational institution, college?
Will be great to get a print head on a robotic arm... no more overhangs :)
4:40 as far as I know, the Ender 4 was an H-Bot printer, not CoreXY.
I believe the motion system on the CR-30 is. Based on the Ender 6.
Correct. Converting an Ender-4 to CoreXY is a common mod since H-bots have difficulties printing circles 🙂
Thanks for the corrections, guys. I haven't ever used one.
Thanks for the video, as the world turns technology rises higher.
Is there an updated printer that can do this these days that you would recommend? I'd love to print parts I print often but they're decor so quality is still a factor I need to keep a priority.
I think this printer really needs the extruder motor right on the print head instead of having the feed line. And the belt looked like it had too much vertical play when the nozzle touched it.
Is it possible to get ur settings? I am having some issues like u did. Thanks.
