Thanks for your service! Just stumbled upon your project last week and today saw it on TT again :) Boo @Sovol for not staying just with mainline...

[@IsiksTech]

Thanks for using the Birds' Nest. I'm glad you like it. Looking forward to seeing this printer in action.

[@LocoHosa]

The Bird's Nest made this project look really approachable for someone of my particular skill level.

[@username9774]

I am very excited about this series, hopefully this brings some more people to try this. I made a Stealthchanger a while ago, it is pretty reliable now, I love it

[@justinchamberlin4195]

Although talk of manually preparing cables and writing firmware code makes my brain melt a bit, I can't overstate how wonderful this whole project is - democratized toolchanger printing is super important, especially for people looking to move away from wasteful multi-color and -material printers.

[@thespacecowboy420]

As a P1S owner I am disgusted by the gluttony of the AMS style systems. I am going to build this when the documentation is done. This is basically a 5 toolhead voron for $1000.

[@Liberty4Ever]

I'm loving this series. I enjoy geeking out, but I have a practical use in mind. Geeking out with a purpose is the best.

[@wsippel]

A small tip: If you just need more IO pins for stuff like a filament encoder sensor, additional environment sensors or what not, you can also get a cheap Blue Pill board and hook it up to the unused USB port on the mainboard. Blue Pills use the exact same microcontroller as the stock mainboard and toolhead board, so you don't have to think about the Katapult and Klipper configuration, and you can easily extend Rappetor's nice automatic MCU update script to also handle your Blue Pill. Even works with the dirty stock Klipper installation.

[@justinschwarz983]

This series has my complete attention. I really enjoy watching your content. Please keep doing this kind of stuff.

[@GoatPrint]

My birds nests arrived today, they look to be very well made. I ordered from Canada and everything was very well packaged. Can't wait to duplicate this effort!

Nbd but really wish Sovol had just used vanilla Klipper. Really would make everyone involved lives better

[@eaman11]

Yeah but the very moment someone hits upgrade customer care goes up in the air. There should be an easy vanilla version available, like OpenNept4une for Elegoo.

[@Reds3DPrinting]

Thank you for your contributions!

[@dlgloege]

Wow! Thank you for all of your hard work documenting this process. I want my next printer to be a tool changer and with your great guide choosing the SV08 seems likely. My biggest concern with the SV08 is the bed. It appears to be somewhat thin and is only rated at 100C. My other options are the Troodon 2.0 or a Voron 2.4 kit from Formbot. The Sovol SV08 is the lowest price but lacks the die hard support community of the Voron. Again, thank you for all your hard work.

[@Reds3DPrinting]

It’ll get there! Just give it some time:) have you made your decision yet? I was in the same position as you, I couldn’t realistically have a Prusa XL on my list as much as I’d like haha.. paying 3500 is just insanity. I hope TT compiles all of these videos in a super simple step by step guide

cant wait for the full build for this comes out, because i really want to build this!

[@kensb2]

This looks like a fairly accessible project. At this point, I've only upgraded an mmu2s->mmu3, and replaced the stock hot end on my MK3s+ with a Revo. I've love to have a printer with a larger build area than what the Prusa footprint offers, but that 4K price tag is hard to justify. I feel like I could add 1 additional tool head, and if all goes well, I can add the rest as time allows. Thanks so much for doing this video series, and like many others I'm hopeful for the final results!

[@sw3dprints]

this is great! keep it up! can't wait for this to be finished to add this to my 08

[@ericthecyclist]

awesome! I can't wait to see how well it prints!

[@marcushannigan]

[@terryevans1976]

Have you spoken with Sovol about getting the software upgrades into their next release cycle? It seems that if they get on board and perhaps even sell a multi head printer as an option that they will make a mint.

[@Justin-cv4oj]

Sovol teamed up with another company for a multimaterial/multicolor solution (Co Print ChromaSet.) I'm guessing they will push that before anything making life easier for alternative and diy solutions. Most companies are going to go for the cheaper all in one single toolhead solution instead of a pricier more complicated multi-head design. Especially companies that sell their own filament because the waste associated with purge towers is better for them.

[@DomingoHernandezH]

I know the cost may be less than the PrusaXL, but with all of this fiddling I can't help but feel they aren't terribly different at the end of the day..(time is worth something as well); definitely more for the type of person that likes doing that kind of thing then just cost savings

[@Sanjay_JT]

I'm able to understand your pov but people like me see it a bit differently. It's more of a thrill that you're able to modify something on your own which is stock. How I see this upgrade series is like the relics of ancient reddit or some old online forum of how someone modified parts an old Buick to make it accommodate the upgrades. These videos may also serve a purpose to even Sovol maybe to bring out a stock multi-toolhead 3d printer in the future. I do understand that in the future there would be huge innovations in the 3d printer space but maybe there'd be a random broke enthusiast who's able to cop this printer from somewhere and upon stumbling upon these videos who'll find this series useful.

[@TS_Mind_Swept]

@@Sanjay_JT like I said, it's more for the person that enjoys doing this kind of thing than saving money (even if it can help you save money directly, if that's your only goal it's really not worth it; it's definitely not worth it for me, even if I do enjoy watching the process to an extent, I just couldn't deal with all the road bumps that would come along with it)

great work dude, looking forward to the final write up, i've been waiting for an all in one half decent MMU to add to my voron, the ercf seems too problematic, but I think this is a better solution all around.

Hi! I love your channel; I find it very educational, and you focus on really interesting and less common topics. Watching your new video series, I have a question. Would it be possible to combine one of the tool changer heads with the ERCF project while using the other heads for different materials? For example, using one head for multicolor PLA printing with the ERCF, along with carbon fiber filament, TPU, and a water-soluble support filament in other. Congrats on the channel! I think it's one of the most interesting ones out there, and the tests you do and the questions you raise are always fascinating and clever. Thanks and best regards!

[@nathan22211]

Note 1: If you're looking at programmers for STM chips that have a "PL" in them, DO NOT BUY! Prolific, who make the genuine chips, have DRM on the driver that prevents older models and clones from working on Windows 11 and possibly 10 if it's old enough, and these are the drivers built into the OS as well. PL chips should work with the Linux driver as I don't think prolific maintains the linux driver. Note 2: Rasberry PI imager can image other SBC images as well and only checks USB ports for drives to image, so you don't risk imaging your boot drive. Note 3: you can use SSH in the Windows terminal and if you're a linux user most file explorers on that OS support SFTP

[@eaman11]

You can use SSHFS on Windows, it makes a mess of the uMASK but you can have it mapped in Explorer.

[@itayst]

Nice project. Note that having the extra toolheads’ [extruder] section on separate files will probably cause some agony when trying to PID tune their heaters and store the values.

I love the new wiring. Along with the cost analysis, would you mind including a time analysis? I would be so interested in how many hours you spent, and then how long you would think the streamlined process would take? I tried the space mouse project and it took me a lot longer then I was expecting. Thanks!

[@westonschmidt3847]

Regarding the cable from the birdsnest to the toolhead - why is a 5 conductor+shield needed when a 4 conductor+shield gets all the signals plus power & ground there? I looked at the manual and didn't see any requirements for additional ground lines. It's pretty common to tie all extra pins in a connector to ground so they don't float, but aren't strictly required.

So what are the improvement of Bird's Nest board?

[@sannaguime]

with all this work i fells like sovol does not want people to have tool change capabilities.

[@sean1hanna]

So Michael, what gauge wire are you using for that 5 core shielded cable? I’m having a tough time finding 18gauge shielded in 5 core. Best I can do here is 5 core shielded 20AWG wire. Do you think that would be enough for the power draw?

[@TeachingTech]

I've ordered some 18 gauge from Aliexpress. Wire there seems to be one step under is terms of cross section, so it is actually more like 20 gauge. 20 gauge is the Voron recommendation so I'm happy with that. It is RVVP which is shield flex cable, so hopefully fit for the purpose. I can't vouch for it until it arrives but here is what I ordered: www.aliexpress.com/item/1005006371513803.html

[@antallaczko8793]

For 4 Amps and 1.5 metre cable, you should be safe with 20 awg. Hotend heater should not draw more than 2 amps, 1 amp for extruder motor and fans is enough.

[@TeachingTech]

I agree. It's just that Aliexpress cable is a bit off in spec so 18awg from them to reach the equivalent of 20awg.

[@kimmotoivanen]

Is it *mandatory* to update Klipper to the *latest* version, or would *older mainline* version, *compatible* with MCU and toolhead, be enough? If I had SV08, hacking a working, _not-so-cheap_ printer that is meant for printing stuff, for a Klipper update, would be _the last_ thing to do. I would expect many printers will be fu _

[@felixyasnopolski8571]

You can't brick the printer by updating klipper version ;) the only thing which may happen - version mismatch, and even though Idk how well it's implemented on the usb toolheads, but with canbus I can upgrade my whole setup without even raising my ass from the chair

[@chrisstone8189]

Awesome! Started buying parts for this build, can’t wait to see it completed! I have been having an issue deciding what umbilical cable to get, most of the dedicated ones are 4 core plus shield 24/20 awg. Having issues finding a twisted/sheilded 3 conductor 24awg with a pair of 20awg for power. What are you going with ? Thanks

[@TeachingTech]

Can't vouch for it yet because it hasn't arrived but this is what I ordered: www.aliexpress.com/item/1005006371513803.html RVVP is suitable for this application. I went for 18 gauge, 5 core, 10m so I will have plenty spare after six toolheads. 18awg from Aliexpress is more like 20awg from elsewhere.

[@kimmotoivanen]

What functionality of newer Klipper are they missing? Klipper-MCU versioning seems to be fairly tight relationship and maybe not really thought out properly. Pi or almost any other "master" (FF AD5M most likely excluded) probably has enough memory to support multiple protocol versions.

[@SippoCoffee]

Has anyone else tried converting their sv08 to mainline klipper? I just converted mine (followed the github instructions) and everytime I "save and restart" from a config file, I get an error and the printer shuts down... (also can't change z-offset from LCD screen mid print and the z-offset macro fails right at the end)... Does anyone else have this issues? Or an idea what might cause them? Also while trying to troubleshoot I compared the new config files to the old ones: They changed alot (from M117 wording, homing sequence, to full blocks of code missing) , sadly I don't understand inove to know which part causes the error and was just able to comment out the diffrences.

[@eaman11]

Beware that if you hold on to your original EMMC as a backup and install the full Linux + Klipper on a new one you will have to upgrade also the firnware on the microcontroller. So if in the coming future you put back the old EMMS thinking at that as a backup it may now work as it's supposed to deal with an older release of the MCU firmware than the one you have installed. In case you should think about a backup of the original firmware as well (if not present in the main OS) and reflash that as well.

[@TeachingTech]

That is correct. If the steps are followed to back up the MCU firmware, it is a pain but this is reversible too by flashing back the standard firmware.

[@krollmond7544]
