Adding more tools! - Budget Sovol SV08 toolchanger part 2

I own a five tool Prusa XL, which is now working pretty well. For many people though, this 3D printer is just too expensive. In this series, we are attempting to take a StealthChanger toolchanger mod intended for the Voron 2.4, and adapt it to the Sovol SV08 Voron clone. In this episode, I answer some questions, add some 2020 extrusions, work out how to add multiple toolheads and complete the wiring for this.

This printer and the additional parts were received free of charge from Sovol for the purposes of making this series. Everything else I’ve paid for myself.

Fingers crossed part 3 is much faster..

I wasnt upset you jumped the queue! You're making content for it which I will use on mine, so I'm glad you had the time!

[luispittairline]

Never clicked so fast, looking forward to what the results are

[fishnet]

I'm only half into the video but I already appreciate your work. Thanks for your contribution to the open source printer world

[woodchukka]

It is modifications like this that has me so interested in the Sovol SV08. I certainly appreciate people such as yourself in the community developing these mods that I would simply not have the time to research to work out for myself.

[JavyFel]

Great content! Love seeing the OGs doing great work 😅 IMHO you are being much to apologetic for the timing of your work. If successful, and on budget, this will be a wonderful option for the entire community . Thanks for the teams hard work!

[DanielSanPedro]

Very very impressed as to how much work and collaboration is going into this. Can’t wait to see it all done!

[radish]

Don’t apologize to the impatient and entitled complainers. The project takes as long as it takes. This isn’t your only project nor is it your most important one…that would be your family. Your collaborators likewise have their own priorities. For years you’ve freely shared so much of your time and knowledge, no one should ever question your dedication to the community or demand output on a schedule.

Looking forward to Part 3, and hopefully the SV08 and toolheads will be easily purchasable at that time.

[DarrylAdams]

You are an influencer and a 3d printing legend. If Tom and Joel can get free Prusa, surely you deserve a free Sovol.

Great job. The fact the extruders are connected by USB is awesome. That makes it so easy to add additional extruders or swap them out with different custom extruders even if you're not going for an automated toolchanger. The aluminium shielding should be soldered to the shielding on the cable (9:30)

🎉🎉 tool changer vid. I ordered my sv08 after part 1 and got it a few weeks ago. I wouldn't worry about skipping the line, especially since they would have to keep some inventory aside for reviews and responsibility problems.

Thank you for all your work and especially your attention to making this amazing documentation

[servermanden]

What you are doing here is so cool. can't wait for part 3

[LibertyEver]

Well done, Michael! Thank you.

I was encouraged by the open source SV08. I was planning to get one, and add my own heated enclosure so I can print ABS. All of our current products are TPU so I'd need to ensure it'll print TPU. Ultimately, I'd like to design some products with ABS and TPU in the same part, so a two tool head SV08 would be ideal.

The Creality K2 Plus is out now but its CFS doesn't feed TPU. Bambu is releasing a TPU that feeds in their AMS so presumably it'd work in the CFS, and other filament manufacturers will hopefully start providing higher durometer TPU as well, which we needed even before these multi-reel filament feeders, just to print TPU faster with higher print quality while retaining TPU's excellent interlayer bond strength, impact resistance and chemical resistance.

.... this series of videos is no doubt the one I'm really looking forward to. Great work, so nice to see the incredible work you're doing, take all the time you need, biggest problem for me is trying to find an explenation for the appearance of _yet another 3D printer in the house_ in a couple of months to the misses :)

[Lyrik]

My case almost identically matches Vikram's. I ordered my SV08 first week of July to be sent an email saying shipping is delayed until the last day of the month, where it will then be sent out straight from China. July 31st rolls by and I send another email; response saying that shipping is delayed to mid-August. And yes, people who waited and ordered through Amazon did receive their printers first. There are multiple reports of this on the 3D Printing Discord server (ad: where I've also made a project post going more in depth on the technical side; currently I'm working through the process of dialing in input shaping. Hint: Sovol did not make it easy). My printer arrived this last Tuesday, but the enclosure and touch screen that I bought bundled with it are still nowhere to be found.
Figured I'd share my story for anyone that was interested or perhaps wants to follow my project post.

*I was thinking about developing my own toolchanger for the SV08 as well, so I'm looking forward to the rest of this series! Maybe I can save myself some time and build your instead lmao.
Edit: since TT's doing a toolchanger, I've decided to start working on Hybrid CoreXY

[tomohalloran]

Great work. Don't apologise for being first to get ur printer especially when ur doing something to add so much to the community.

[bmorr]

The is my favorite project I’ve seen and I love being brought along rather than just shown the final result. I’m excited for the next episode.

[thetredog]

Seriously…. No stress between the videos. Like everyone, I’ve been hanging out for it since you posted the video. But people need to realise that creators have a life too. Keep on rocking. If I see you in person, I’ll buy you a thank you beer.

[Bengamzo]

Good job Michael, I personally don’t own a sovol machine, but it’s great to see people push 3d printing to the next level
Keep up the good work 💪

[flyingbaldman]

This is such an awesome projects. I really hope the results are half decent. If they are, I will build one of these as soon as the files become available. This seems like an awesome hobby-engineering project to do. And, I have been eyeing the Prusa XL for years now, but can't justify the cost.
Anyway Michael, Draftshift team and others helping, thank you very much and keep up the good work!
