I Got The ERCF V2 Working. Here's What I Learned.

[@thenextlayer]

Thanks for watching! Let me know what you think in the comments. Also, check out the merch I wore in this video at shop.thenextlayer.com

[@Splarkszter]

SOVOL IS A TOXIC COMPANY. PLEASE DO NOT WORK WITH THEM.

[@ivantrail702]

Welcome to the club, my friend. I'm glad you're here. Thanks for sticking with it. 👍

[@thenextlayer]

Thanks for all your help. Still working through lots of issues though! But soon…

[@3dpathfinder]

Teaching Tech is also working on a 5 head tool changer for the SV08

[@thenextlayer]

Yep! He inspired me.

[@duck_that_quacks]

hook up one 12 channel ERCFs to each tool head for 60 colour printing😂

[@peterrichards1989]

@@thenextlayer Are you guys going to collaborate on it? Two heads and all that :)

[@bryanswift6301]

I always enjoy watching your videos. This reminds me that I am not tech savvy enough to build one and I’ll stick to my plug and play printers. I do really appreciate the level of skill and knowledge required to design and build one of these.

[@bajojohn]

This is one of those projects that I really want to do, but I think I will wait until it’s a little more mature.

[@samhale5413]

This has been impressive to watch you build. Mad props for not giving up.

[@adcrane]

Great video with a heap of valuable info for anyone building, or considering building an ERCF. Very much appreciated, particularly sharing where you struggled.

[@TiagoJesus]

I have the ERCF v2 kit and the Voron Trident kit. The challenge will be to put the two together . Thank you for making the path easier. 😁 It would be interesting to post some videos on different ways to reduce waste, as you said in the video. OBS: I've already built the Voron v2 and v0.

[@TomN3rdZone]

..and as always. Your attitude make your videos even more worth seeing !

[@Flockman3065]

Massive respect for this valuable resource, i've been looking at undertaking this for my Voron 2.4 glad to know i can benefit from your journey

[@3dpathfinder]

I admire all your effort, but I can truly says that this is not a level of ticker id be up for. Great work and here's to who ever has the will to see this through. Not me , I know myself enough to say I wont be trying this.

[@thenextlayer]

I can honestly say that if I had known everything it was going to take, I would never have taken it on. Maybe as a hobby, but, definitely not as something I plan to make content about. Note how I haven't put out a video in WEEKS...

[@Scrogan]

With another year or two of improvements, and some plug-and-play clones from the usual suspects, I can see it being good enough to recommend to users of voron clones at least. But probably not ender 3 users.

[@TheMNWolf]

I do have a suggestion for the cutting arm. Instead of printing the holder and then pressing the knife into it, add a pause at layer to the print file on the first layer above the slot. This will pause right before it does that layer. Assuming you're printing in ABS, dab some acetone on the blade, hold it in the slot for a few seconds until it sticks, and resume the print. I went through four of those tool holders before I figured that out.

[@marty4286]

Congrats on getting it working! I'm now finally tempted to order my own ECRF

[@psmithrpm]

Super valuable contribution of useful data. Thank you for all the work you've been putting into the ERCF!

[@dooleve]

I opted for the Trad Rack, it is a lot more straightforward both to build and operate compared to the ERCF. Cheaper too.

[@MallocArray]

I'm interested in TradRack as well. I recommend TNL do that next

[@rtr56879]

Its like you were looking over my shoulder for my own stab at this thing. Glad you stuck with it and what a great resource this will be for the next guy. Cheers 🍻

[@Ituran1]

Thank you so much for all your work! i have already a kit laying aroud and will try to get it build and running, when my replacement Nozzle and PEI plate comes from Sovol for my SV 08! Thanks for all your tipps!

[@GregAtlas]

"Is it worth the challenge of building one of these instead of waiting for creality or anycubic to actually unlock their systems?" In my opinion, yes. Unfortunately, these companies that make our 3D printing products often have really bad firmware or are really inefficient. Being able to make your own and tune it just the way you need it is priceless and these companies don't have a reputation of allowing or supporting that. You always end up limited. The exception being the Prusa MMU since you can tune its firmware, but that involves going back to the Marlin ecosystem and also costs quite a bit.

[@karlh6692]

Love it! I can't wait to see you get the toolchanger going to get a feel for how easy it is in comparison.

[@thenextlayer]

lol. Real talk.

[@klaiddias]

Very good, congratulations. Waiting for updates primarily suing ERFC V2.

[@DarrenGerbrandt]

Currently waiting on my kit from Fysec. I'm looking at this as both a challenge and a project. I haven't built a Voron but I have converted both my Ender 3 Pro and Max to Klipper, moved from single Z lead screws to dual Z belts, upgraded the hotends to Revo CR with Mini Sherpa direct drives with HM7 shrouds. While I doubt this project will be even a bit easy, the harder part will be how to add a cutter to the HM7 shroud some how but then I may change my mind on which is harder when I actually start the build 😁

[@slonlo364]

So this video definitely made up my mind. I love open source projects, I love building things, but this seems like way too much for me, at least right now. I'm definitely becoming more of a product guy than a project guy. Or rather I like projects I can knock out fairly quickly then enjoy and move on to the next one. This does not seem like that. It looks super cool and looks like a blast to figure out, but I know the frustration would get to me. Great breakdown! And great video as always!

[@ashers_workshop]

Awesome. Thanks for making this video!

[@DR4K0R3X]

I started working on this after i saw your other video, thanks for the tips! I guess I better order that servo before i get much further 😅

[@esurfrider7687]

Way to power through bro! Challenging project, I’m interested in multi material systems but I have yet to see really valuable implementation of the tech, I have some ideas but I wouldn’t go down that rabbit hole unless I had a million dollar product idea that I really wanted to develop at home.

[@marinermerrill3884]

Very informative as always. Really love your content!

[@xxlyfexx1447]

Subscribed and I’m back, I had seen your video posted a month ago just 2 days ago and was just looking for the next video so glad it just came out!

[@xxlyfexx1447]

I have no screen for my printer, though I’m going to setup an Estop now after hearing the first few min!

[@C3DPropShop]

I built a 2.4, and I love my voron. It's pretty much the only go-to printer I use these days.... but if i need multimaterial, I would have a serious look at bambu. This is just too much for me. I guess I'll just stick to single colors until this PROJECT turns into a PRODUCT. Happy printing.

[@mariospanayiotou6644]

What i would love to see you experiment with is multicolour without any “purging”. Meaning you swap filaments without purging or cutting every few meters of filament, sort of creating your own custom dual, triple rainbow etc filament

[@Scrogan]

A tool-changer can at least be expanded on. Start out with just one extra tool-head. Add a third only when you need it. I was thinking you could do the same thing with filament multiplexers, by having filament dry boxes that each have their own stepper and bowden tube running to the hot end. The hot end would still have its own filament cutter. Then you just add another filament box when you want another colour. You might be able to drop the filament box price below $150 each if you really try. The expensive part is needing a servo and stepper for each box, but there might be shortcuts around that without impinging on the modularity. Like bowden cables from a single servo.

[@TrinomCZ]

Both multi material unit and multi extruder setup are awesome projects. However I see a significant difference in use case scenarios. Multi material units are mainly used for printing in colors, using the same type of material. On the other hand, multi extruder makes great sense for engineering use, where multiple different materials are used, either as supports (HIPS under ASA), or as aditional parts (TPE gaskets for example).

[@jerrari3D]

Heck yeah! Nice work Jonathan 👍

[@AtomicBleach]

Going to be interesting to see you get this working paired with some recycled filament. Im sure youll come up with some really wild color choices for multifilament prints. Especially if you slap some purge blocks and filament poop in the shreader!

[@Zetler]

That intro was glorious.

[@TheMugwump1]

Thankfully I didn't pull the trigger on one of these. My options now are to just give in and get an AMS for my P1S, or go with tap/stealthchanger, but there's just not enough info on it for me to feel comfortable.

[@linkin987456]

You just saved me from epic level failure. I have an MKS Skipr board, reflashing a new os is a whole other problem. It may not even be available

[@KitGerrits]

Man, I need to give my BBL AMS a hug. It takes forever to switch, but took zero effort to set up. I just want to print and don't have the headspace to build my own. Have you looked into the later BBL/Orca versions that try to cut off a smaller tip for less purge?

[@thenextlayer]

Truth.

[@thenextlayer]

Does newer orca cut the tip?!

[@mustafaatatuzun]

Well done man.

[@MrTrockc]

Yep, harder to build than an actual Voron but..my record is 41 swaps so far! Thanks for the filametrix mod, I'm printing this asap.

[@Monopek_Cannibal]

9:22, I also noticed this strange (nice) feature of the K1C (without additional settings in the slicers) is that this 3D printer is quite accurate. Even if it is slightly inferior in print quality to bamboo in stock condition.

[@thenextlayer]

Agreed. It really is a phenomenal printer. Everything the K1 wasn’t. I actually think the print quality is superior to almost anything except maybe the new MK4S…

[@VasilyKhoruzhick]

Thanks for the video! I'm really interested in ERCF and unfortunately there isn't a lot of videos about it on yt

[@oOWaschBaerOo]

the ebb35 btw has enough ports like plenty.. i got endstop, filament sensor, klicky installed plus i have 3 more gpios left over one currently controlling my pwm for my 2 part cooling fans, i could technically use the last 2 for more sensor or rpm sensing even

[@jasonjennings6686]

Agreed! Just need to read the pin out schematic and you can find plenty of pins for other items

[@MrBooth1974]

Awesome video my friend ! I’ve been thinking of tackling this project after my Zero G Mercury upgrade is complete. I was already considering changing up to a Stealth Burner, and this has pushed me towards that even more now. My only question is why they aren’t using thrust bearings on the pulleys you said you had to keep sanding down till the spun. You can get them pretty small and are ridiculously inexpensive.

[@andrewesquivel]

i think....i might be one of those people who does this project... But I wana do it a bit different. I came from years of Marlin. So Klipper has me going nuts with excitement.

[@aaamott]

I'm working on my own toolchanger, and each tool can be as little as $20-$30. Tested once, but I'm working on an updated tool,auto X Y Z Offset, and a better purge bucket. Not 12 colors though lol, but I'd love to see toolchangers with an ERCF on one tool.

[@thenextlayer]

How can it be so cheap? What hot ends are you using????

[@aaamott]

@@thenextlayer KZbin seems determined to delete my reply... third time's the charm. Guessing it's the link. I'm testing using bambu lab replacement hotends from China. $8 where I am, plus a CHT nozzle ($2 each). Combine with a cheap BMG kit ($6) and motor ($7.50) and 3010 fan ($4) and a pair of 4010 blowers ($4) and you have a full hotend. Or drop the 4010 fans and use the 3D printed CPAP-style fan from Mark Rehorst with a single air duct for all the tools. Or, of course, a real CPAP fan.

[@sebastiankarafiat796]

i'm surprised you got the passive puffersystem running...also working with matte stuff, CF Filament, and so on? I'm close to finish my vcore 500 with 9 channel ERCF.....but i had to develop electric rewinders(just way too long bowden tube), a breakout board, the hall effect sensor was crap, extrudersensor (orbiter filament sensor) also crap....rebuilt both of them with ball bearing switches and long switch tolerance....same experience with the servo as you had....oh yeah, and a purge chute is needed....and when i thought i am finished, beacon has an upgrade for true zero measurement, means i need a brush for the nozzle....by now it reminds me of a giant bambulab printer....but it's a neverending story to build something like that

[@GadgetReviewVideos]

Congrats! Hmm not allowed to talk about it. I’m Thinking mini-lidar add on 😊 A good servo with torque and metal gears makes a big difference. I’ve been running things with servos for 30+ years and it will last much longer.

[@Todestelzer]

20:13 try and replace the ptfe tube from the wiper with 6x 6x2mm silicone o-rings. No poop on the build plate anymore.

[@chidswick]

I'm in the middle of building one of these and your video flashed up on my feed. Luckily it did ! I have just started building the selector tool and your comment on the servo made me dive straight into amazon and buy the Savox. Luckily I am in the UK and the company selling these are also UK based, so the cost wasn't as steep (23 GBP).. anyway, that's not the point - the point is you have probably saved me a lot of heart and headache. I am stopping production and printing the parts, awaiting delivery on the servo ! Let's hope that is the thing I have to worry about anyway. I do have one question that you may be able to help with - Filametrix - how much filament should be unloaded before the filamtrix cuts, or does it cut and leave a strand inside the toolhead - I couldn't get my head around how a new piece of filament is supposed to follow up on a piece that is left inside the toolhead .. but your video suggests you unload a bit, then cut, leaving only a small strand? Thanks for this video, I am subbing to your channel !

[@thenextlayer]

Thanks for the kind words

[@natdizzle4259]

Anything over seven colors I feel like the ERC has a lot of issues the tradrack would be a great comparison for you it's extremely similar to the ERCf but it's easier to build not as wide and you can add on way more modules before you start to have the issues of the ERCf

[@crocblanc01]

I haved own the v1.1 and convert it to v2 (i'm part of dev team) so i don't have some difficulty to build and tuning it. But i run it directly wired on the MB and don't have the cutter installed nor led. My first print after calibration has 561 swap and print it without any error.

[@k0mpreni]

Very nice one! Stupid question, but is it available for all printers? Would love to have it on my sovol sv06!

[@thenextlayer]

It'll work on any Klipper machine, with adaptation. See the first video in the series I did on this.

[@thorjohnson5237]

This looks really cool and it looks like it's time to build... If the tool changer is USB and this is CAN does it all feed into the same printer mainboard?

[@thenextlayer]

It can, yeah.

[@makermylo]

Upgrade the stepper to a beefy Nema17, install a 40T Wheel instead of the 80T and you will be able to do filament swaps in

[@thenextlayer]

Confirmed or theoretically?

[@makermylo]

@@thenextlayer Confirmed, its what i have on mine and its been reliable for months. Also, check out Filamentalist respoolers, save yourself the headache of using buffers.

The challenge for me is humidity because of where I live. So, for now, I stick with the way more expensive BambuLab AMS.

[@flaviomathys1196]

I'm in the slow process of researching everything before starting this project. Currently i'm trying to decide if i should build a voron for it first or change the toolhead of my corexy ender 5 pro to a stealthburner for it.🤔

[@squishysquare8222]

7:11 ive also had good luck with the MG92B its quite a bit cheaper as well. @ 6v it has 3.5kg VS the Savox's 3.9kg @ 6v. yes thats at 6v and not the 5v the ercf will run it at

[@slacksthegreat]

Im definitely taking this on soon

[@thenextlayer]

You sure...? LOL.

[@DJProPlusMax]

Cool, but considering it is even more difficult to build than a Voron, which I myself haven't yet built, I think it'll be quite some time when I get to an ERCF. Right now though, the E3NG seems interesting...

[@Bob-x2h]

Hey, Im a manual wheelchair user and I was wondering if you could print a wheelchair frame? do the make the printers big enough? I'm very new to 3D printing

[@philevans4021]

How on earth have you managed to get your purge multiplier down to 0.35? I have exactly the same setup (Revo, Filametrix) and definitely cutting as close to the tip as possible, and with some colours I still get bleeding at 0.8!

[@thenextlayer]

Ummm not sure. I just tuned it and cut the tip pretty minimally…?

Sorry to be a wet blanket, but at 2:18 I'm thinking what a PITA to implement. Still the overall build and EVERYTHING that went into it is Cool AF. Still thinking that this might need to be implemented from a ground up build instead of a "retrograde"? Printing the parts on the same printer for consistency might prevent insanity..... OMg this is nuts...... but still Very cool..... How many months in total did this take?

[@thenextlayer]

Honestly can’t say I’d do it if I’d known what it was going to take

[@TomN3rdZone]

At 14:27 you show your top of the printer with the "inlet" for the filament. I am looking for such a thing - what is the name of this ? I would like to add a BTT SFS2 on top of that thing..if anyone has seen such a mystic mod..feel free to share a link !

[@korriehusky8404]

This sounds like it's more work than it is worth.

[@DiomedesDominguez]

10:47 "soon" they have months since that announcement without any feedback or updates with new pictures to say the least.

[@thenextlayer]

There is progress behind the scenes, I can’t say more.

[@ritiksadh1999]

Is this ERCF project compatible with any open source printers like creality, anycubic, etc. Or only with diy voron printer ?

[@thenextlayer]

Theoretically any

[@BrianVoelker]

Everything new starts out hard. Then we figure out easier and simpler ways to do things. We are at the start.

[@orthotron]

Purge waste is pretty high on high flow hotends. There must be a better way of doing this. What if we used a puff of hot air to clear the melt zone instead of feeding in more filament?

[@CurtisCreations402]

How about the 3d chameleon? have you looked into this one?

[@3dPrintingMillennial]

Do you think resin printing the small parts that needed to be really precise would've prevented a lot of this headache?

[@thenextlayer]

They’d likely break with the force of the Savox

[@mrcrackerist]

What about a tool changer with multiple ERCF's?

[@thenextlayer]

I barely survived building one!

[@redwhiteandbluebonnets8180]

19:33 Wow, Klipper supports a mohel! Mozel tov! ;)

[@Todestelzer]

Had to install a new Linux version because of python too. Took my 8h till everything was running again… Need to install the filament toolhead cutter. And still on ERCF 1.0. the kits for V2 are pretty expensive.

[@thenextlayer]

I feel your pain...

[@thejumper9303]

Hmmm, so trident with iedx and a ercf on one of the toolheads is the real way to go. Cheap and multi print tempratures

[@charliekealoha]

Ok, I'll just wait for the coprint project to release. LOL

[@dmitryplatonov]

Servo lever needs bearing on the end to reduce friction.

[@ThisisDD]

Looks like fun! That being said, gonna look at Coprint lol

[@SianaGearz]

I think all of this hardware is too complicated. Classic cheap MK8 extruders and stepper motors, one set per spool. Arduino Uno with Klipper connected over USB. CNC Shield on the Arduino Uno, 4 stepper drivers. 3MS for Klipper. Does that sound like a plan?

[@jeffrbake]

So would you recommend this or a tool changer

[@thenextlayer]

Depends what you need. Haven’t done a tool changer yet myself
