The Ender 3 S1 Prints Better In Reverse? 

I was so upset that all that 3dprinter videos were serious... And boring Bit this guy... He's different. He has that old fashioned English sense of humor built in . Luv ya wigga

Lol more pepper, man. I love the focus on casual curiosity, that is where great ideas come from.

You've got great comedic timing & editorial craft. My favorite FDM printing channel by far. The design flaw really looks like a miscommunication in house at Creality. Like the designers were overridden by someone in charge of production who was cutting some corners,

Sir. Great video. You explained it in a manner where an intimidating subject such as 3d printers operation design is not longer as intimidating. You remind me of that hard working employee that sees the bosses make the dumb and inefficient decisions they do, so you took it upon yourself to do it the right way, even if it is not profitable for the company at first. Eventually, when trust is gained, profits will come.

Best episode of CSI I’ve ever seen. YYYEEEAAAAHHHHH

My take away was to put my camera on the back side. Now I can clearly see the nozzle and all print activity!

Impressive work Nathan Builds Robots ! At 11:01 we can also see the air flow pattern deflecting some of the pepper out and away from your pot containing the water. Great work with your video and information. Plus your sense of humor is great !

Great video, a lot of valid points. The detective look is great, very 80s. Instantly thought you had an alcohol problem and a wife cheating on you.

I've been using my s1 backwards too! I just unmounted the display and physically rotated the printer around so I'm looking at the entire back lol

funniest guy on youtube hands down. you almost drowned that hotend in pepper water

I think the non-stalling pressure front where the two fans meet is a happy accident from residual flow speed bias on each nozzle exit imparted from the non uniform exit characteristics from the centrifugal fan exits. A fair bit of thought needs to go into good ducting design. I suspect a lot of further improvement could be made.

Love the 3D Printer Mystbuster Show!

The creality sermoon v1 has the sprite this way around and has the 4010 fan mounted underneath, just behind the hot end. Its great to see everything for sure. I might give your fans a go!

20:25 It's a major issue with your design imho. If you want to see the nozzle, just put it on the other side of the X gantry...

i wanna come back to this and just state that there are many remakes of the s1 apparently, the extruder (sprite) appears different like its been flipped with a front plate put on and in even newer or recent s1 I have seen like the link below for Amazon it looks like it got a complete makeover!

To add to your backwards design theory: 1) some people have found that placing a 5015 fan against the stepper motor stock configuration can result in magnetic interference with the fan. 2) keeping the heavy stepper motor closer to the mount should improve stability due to less torque at the mounting point which I'm sure you've already thought of, but I suspect this is why the sprite printers come with the 2nd mounting plane to reduce the instability this likely causes.

The deep dive on wheels sounds really interesting.

Well, all the marketing material shows the back side which, as you pointed out, is actually under the breakout board, and I think in your CR-10 SE review you also showed that they are now using it flipped as you did in this video, so I think you are right, they designed it to be used in that way but changed their minds for some reason 👍

Here's one of my thoughts: When you design a 3D or maybe 4-5D printer, I'm going to buy it.

Oh nice, I spotted a Knipex 1/6 86 05 150 or similar model of plier wrench.

Creality made the sprite extruder this way for one lucky creator to really deep dive into it like an investigative detective. Now if they see it maybe they'll be able to save money from creating new supply chain products! 😂

Oh yeah.. this is a doer... Im on it now... Going to love bringing back the great panaramic print view again and not worry about the original smacking me in the head while using the magnifying glass when looking at the print nozzle doing its thang!. LOL 🤣

Great video Nathan, is the modder board available internationally now, or is that in the future?

hah i keep my ender backwards ! I thought i was the only one

Your actually awesome Nathan, just got my modder board of you and it’s brilliant!! My S1 pro has finally turned into the machine I wanted it to be :) thank you, I also have got a K1.. it may have bad reviews but so far it’s been doing great and it’s easy to print and not worry about it, your videos are great and I love watching them

I have a tevo tarantula Pro that I modified the hot end using an all metal E3D v6 and a BMG extruder along with dual spandex and the beauty of the whole thing is is the motor is on the side attached to the extruder and the V6 hot end is directly underneath and invisible the way it ought to be. So Make a hot end where the stepper motor and the extruder are rotated 90°.

remember to always use freshly cracked pepper for your flow visualizations

That's a totally different design 🤗👍

Another GREAT video. I hope Creality buys your design, and pays you a million dollars plus 50% of all profits for the rest of your life.

21:15 thinking things through before releasing them? creality couldnt hear that comment because they were too busy laughing over the sound of money counting machines. see ender 4 and ender 7 as prime examples

premium content 👌 love the special agent

I like the concept of your idea - increased visibility, easier service, etc, and would like to see you take this through to a complete upgrade package for you to make available. Maybe a linear rail would be a solution for the increased offset ? Creality is probably looking at your idea and might use it in a new model when they get over having their ego's hurt. I wish you luck in finishing because your idea looks like the better product they originally "intended".

Hey Nathan, great video. I like the humor so i hope you keep doing that on your next videos 😄. About the extruder, I think its not supposed to be backwards like you said but sideways like the BMG extruders or Hemera design. The handle you press the release the pressure would look towards you that way.

I bought an ender 3 s1 pro a couple weeks ago. It's my first 3d printer. I have no experience before this printer, and it still felt like it was not supposed to be designed the way it turned out. It seems like it's putting way too much weight away from the gantry. I don't get these people that redesign theirs to put more weight even further out. It seems to me like doing that would make exaggerate any bumps and jostling back and forth and cause the nozzle to dig into what it's extruding. I also noted what you said about those heat fins being covered up. You don't have to be a genius to know that covering up heat fins, which are intended to bleed off heat, can't do its job. Why the hell would you design in heat fins that go nowhere? I think your right about everything.

I actually prefer the front part, it looks pretty nice to me

Goddamnit I've had that polarity switched around fan between my S1 and CR4 and it almost fucked up my printer. It drives me nuts. Fucking Creality man...

I wish you success. appropriate amount of jokes for this video I'd say 😅

I wonder how well this design would work with a stock heatbreak and two 4020 blower fans. This looks awesome! I love my modder board but will be looking forward to a video on your next one.

so many people are obsessed with the ender 3s1

Awesome i have thought this for some time now

I think you've made a fantastic video and the production quality has increased significantly, really good job overall keep it up ! Not all your jokes landed but damn did you keep me entertained 👍

Great video! Don't get me started about Creality....

Great detective work! I want to join your force😁

Huge fan. I just finishing of my heavyly modded ender 5. Not the stuff that everyone does.mine has 3 screw bed a true z axis floating bed and the sprite extruder modifide to keep full bed demension. I would like to show you.

i have no idea why everyone is bothering with fan mods. This printer prints best at 50/60mm/s, maybe a tiny bit more..the 4010 fan it comes with is more than you need for that. Why would you sacrifice quality and put stress on the components, just to make a point that you CAN print faster.

In regards to that breakout board,Haha check this out. So I went to put on a new hot end the 300c one and once I got it all together the little plug on my new thermistor was too small. After doing some research thinking I got the wrong part I eventually realized that my E3s1 has a manufacturing flaw. The thermistor connection is much bigger on my board then everything I see online and part wise, mine is more like 2.0 or 1.5m. I came to the conclusion that Creality must have got a batch of the wrong connectors and just decided to use them. This sounds like your backwards 1.25 thermistor connector its an issue with the same thing. Interestingly enough I have actually bought 2 E3s1 from the same store one is kept unopen and I wonder if it has the same story going on.

Starting this mod today, do you have the x,y offset for the new CR touch location by chance? Thanks!

Where is the pre-order for the new board? I don't see it on the website.

I don't remember to see any discussion about where to take the air for the parts cooling of FDM printers... temperature may change a lot. I mean: Should the air have the bed temperature? Maybe, as it's supposed to be the temperature we want for the part being printed. Or should it take air from the room, colder? The part will cool better in that case... right? Cheers

Good video!

I could watch you apply boron nitride paste all day. ;)

Thanks Nathan, I always enjoy your video's even when I'm decrying them! :-) I suspect you are right about the way the Sprite print head faces. I *know* you are correct about the difficulty of seeing the printing nozzle because that has always bugged me about it too. But when it comes down to it the main thing is the quality of the print output and I give credit to Creality for realising the nozzle needs to be as close to the X axis as possible and not opting for the best looking result - yay, engineering triumphs over 'the look'. The result is extremely high quality prints at the moderate speeds the printer is designed to print at. The print head is nice and narrow so you can see the nozzle from the side pretty well. My solution to faster printing is to run two printers simultaneously - I'm doing that right now. Even the cooling fan is fine for printing PLA at 50mm/sec so I don't see the need to touch the Sprite at all - I think its perfect in the context of its intended use. I'm very intrigued by your video's on high flow printing and the general buzz around printing at higher speeds using Klipper with Core XY machines on rails. But I think to explore those paths you need a different machine or dedicate your modding of a machine for one of those particular purposes - expecting one machine to fulfil all requirements is unrealistic . I also think there are technical problems with high speed printing that aren't yet fully overcome - the drawbacks of rail systems, the need for a light print head that at the moment forces you back to a bowden setup for the lightest configuration. I would like to buy an Ender 5 and play around with some of these options as I think that format of printer suits Klipper better than a bed slinger and rail conversions exist for it too. Oh and you've got a new patreon - keep up the good work and keep enjoying yourself as much as you seem to!

Great video! The duct design is impressive, would be interesting to see how fast you could print with the increased cooling performance

I have two noctua 4020 from the previous design, is it possible to make one thay works for that? also, if using the factory heat block would this need modification?

It looks so cool!

I’m assuming this shroud only works with the backwards-mounted extruder?

Did I miss where you posted your fan duct model for the reversed hot end? I would like to try it out.

ok, im in ^^ lets bash crealty while owning at least one ^^

Listen all y'all it's a Sabotage!! But seriously, great video!

The only thing I was confused about is why you had to cut down the heat break? What am I missing. Ordered your board so I can perform this mod on my ender 3 S1

the reversed polarity jst connectors from creality is down right evil and borderline criminal. i fried one of the fan traces on the board almost exactly as you show 24:33 but i think just one or two traces to the right of that one you show. since ive done that ive tried to search through hell and high water for a stock pcb sprite pro board but as far as i know you cant even buy just the board alone. once again, creality probably does that on purpose so you have to buy the entire extruder. which is where the criminal aspect of my rant comes in, lol. however the bright shining light in my search of the pcb is that i came across your modder board. it was like a hand given gift from an angel that pierced through the hell and high water i was stuck in and brought me back to the light. it is going to be such an excellent upgrade. thank you for what your doing for the community, we all greatly appreciate it. i just need it to be past the new year already so you can ship it to me ;]

Nathan, great work! Love what you did to an already decent printer (IMHO it's good for someone who just got into 3d printing and has no experience whatsoever and just wants to print). Will you be selling complete kits? Also is the board green or black (I want the black one to keep design matching 🖤)? And lastly, shipping to EU possible?

I don't. have one of these, but could you not just turn the gantry around

I'd like to see someone wire up a small pinhole cam to an extruder then be able to view it on the screen / Sonic pad maybe. That would be awesome. No more need for a webcam or flipping extruders around. But it's gotta be 4k ;)

What is that heat block you've installed???? I can tell it isn't stock. I'd love to know!!! Thanks!!!

i REALLY NEED TO DO THIS ... Great video - I've just got into 3d printing 3 weeks ago - ender 3 s1 pro , I hope to think I am right in thinking it fine for this, meaning if I get your breakout board and print ducts etc - yes ? As I've used noctua fans for modding a ps3 and ps4 and know how good they are - I think the idea is perfect and looking forward to getting it on mine.

Finally someone confirming that the S1 is basically an overpriced bad design. Creality started off great with the simplicity of the Ender3, but went only downhill the past years...

You should almost just buy a cam bus run fuor wires and be done with it 😅

Edit: no matter what, I'll be buying your board so I can add things easier. Kinda want a volcano hotend with a CHT. I have a CHT mk8 on the stock block. Need a second fan without splicing wires and buck converters. Lol Original: How well does this cooling work for faster printing? I can't get the bow of my PLA benchys to print faster than 50mm/s, without at least starting to curl and grinding the nozzle on the last layer. I even put a desk fan, right up on the front of my print. TPU.... Ugh, I gotta print at 10mm/s. 😂😢 And I have the reindeer antler part cooling fan from printables.

My S1 Pro's extruder just died during a print. Spins smooth by hand, locks when commanded, but wont extrude or retract. Just clunks like a motor release then nothing. Motor or driver? If I could plug in another stepper I could find out but......thanks Creality

Would this work for the 3s1 pro as well?

Good, Video thank you.

So you complain that creality locks you in. On the other hand you sell the modderboard and put the project files behind the Patreon paywall. And it worked with me. I bought the board and became a patreon. Still, same thing, wouldn't you say?

This will be my first mod. I got a k1 2 months ago. Just picked up an s1 to I could do this for fun. Do you just flip it around? And that's it? Also do you have any suggestions for that trimming on the hot end you did or is it just obvious once you get to that step? Also.. Will all this work for the regular s1 because I just picked it up at microcenter for 150 tax included and didn't wanna pass it up.

With the air shank design, how do you set x,y offset with sonic pad/klipper? Mostly trying to figure out parameters for bed level manual/auto. It tries to level out the bl touch about an inch in front of the bed.

Hi I have an ender 3 s1 and I connected a fan to it and it gave off a burnt smell and now the fan doesn't work I tried to change the fan I tried the motherboard in the extruder and it still doesn't work I would be happy if you could tell me if you know what the problem could be

NBR when will the second batch be ready? can i order now or should i wait?

I have a brand new S1 Pro that hasn't printed yet, I plan to install a Sonic Pad on it and other mods right out of the gate. Is there a version of the hotend you use that uses the stock type nozzles? I have already invested in a diamond tipped nozzle and don't want to have to change to totally different nozzles than my V2 uses.

This works with stock board ?

Question. By moving the hotend towards the front I'm assuming you won't be able to utilize the full build plate? Wouldn't it move all the prints further forward and not be able to print towards the back of it?

what hotend is being used?

I was thinking of building a fan duct using copper brake pipes and a manifold to direct the air close and directly to the printed filament as it lays down, can anyone think of any reason this might not work or any problems that might be encountered in this endeavour?

Now that the good looking side is facing forward, all you have to do is make it look good. Clean up the rats nest of cables and use a matte filament, like hatchboxes magic stone or something. And I suppose the modder board doesn't need to be on the extruder so extend the hell out of the rest of those cables and run them along the ribbon to inside the printer. Modder board uggo bro. One of the main charms of the sprite hotend was it's form factor and extreme density. And you just went and splayed it all out like a hooker on PCP. You tried taking a few steps forward but stumbled backwards and landed on your ass with this attempt at making it look better bud.

So how did you put the hot end fan in?

Can you use PLA as a Printhead adapter? I would like to turn mine to the side for reasons.

what is that jumper like thingy you tested on the stock breakout board? Mine got ripped (already ordered your board)

How can i obtain the fan hotend stl

HaHa. Love it!

😂👍🏻

la mera neta se mira fea y no veo la mejora mas que puedes ver sin pedos

BLTOUCH lol. Should make a comparison video of BLTouch on a Ender 3 S1 Pro and also the 3DTouch. Don't you just love how the Chinese rip off patented technology and call it their own? I think it's just crazy how on their websites they'll tout the fact that they have patents because it's really easy for them to take someone else's patented tech and patent it in China. It's like hey look. Here's our open source 3D printer, but it's patented by us in China. Take that Western world!
