Rat Rig V-core 3 part 1 - Premium coreXY 3D printer community build

I’ve wanted to build a top shelf 3D printer kit for a while, and now I present part 1 of the Rat Rig V-core 3 series. This appears to be an outstanding design: rigid, high quality, modular and containing amazing features such as a three point self levelling tool plate bed. My patrons helped me choose this and so far I’m very happy with it.

In the first episode, we cover available options, why I chose the Rat Rig, unboxing and components, 3D printed parts, the electronics panel, and the first six assembly stages. The Lowrider2 3D printed table top CNC even makes an appearance!

Next episode will feature the EVA carriage system and the rest of the assembly. Which hot end/extruder combo should I choose? In the future we'll be setting up Klipper and pushing the machine to its limits.

This kit was purchased with my own money, apart from the shipping which was provided free of charge by Rat Rig. All opinions expressed are my own.

when he said ''I'm thinking of making a CoreXY 3d printer this year''
i was like WHOA!!
this teacher never fails to surprise us. Respect!!

I was already looking for a core xy and then you make this video. You are always on point with a tutorial just when I need it. First for the skr board then the bl touch. The best 3d printing information.

0:50 for clarification the V in voron doesnt stand for version but for Voron and the voron 2.4 is in conjunction with the 1.8 the oldest up to date model of a voron. They're diferent machines not versions of the same, and the vorons you can build are Voron 0 (V0), Voron 1.8 (V1.8), Voron 2.4 (V2.4), Voron Switchwire and voron legacy. Besides the legacy (which is a tribute to older printers with rods and stuff) all the vorons are diferent machines with diferent up and downsides to which one.

Been watching dozens of hours of footage concerning the Voron 2.4. One video of yours about this RatRig, and you've made up my mind. 🖤 💚

Can't help but notice your Senna hoodie.. Glad to see some people still remember Ayrton Senna.. :)

I ended up doing a Voron 2, and I am a happy man.

Great video, when I decide to build a corexy, I'll know what to do.

With a plus, using a ratrig kit, straight from Portugal 🇵🇹👍

I have 2 of these at work, which I built. The 400mm pro was a pain in the ass to get that huge bed to work right. Now they have the rails at the bed corners which solves the problem I have.

Another interesting option that in my opinion deserves more attention are the annex engineering 3d printers. What sets them apart from the others is that all the printers of the project are cross gantry, so four non moving motors instead of two, and shorter belt paths compared to the coreXY kinematics. The speed they are capable of is insane!

Well done Michael.
I'm sure you will love this beast.
The frame is a tank and the "moodability" is awesome.
Let's see what you think of it. Something (maybe) half the price of a Voron.
Waiting for the next one, best regards from Portugal.

BTW, if you need anything, just let me know. I'm close the the guys in Ratrig ;)

[tomaski.]

heeey that @2:56 looks familiar! :) thank you for the mention. glad you liked it

[moccaloto]

This is the best 3d printer kit build video. I almost bought a Voron kit, but now I lean towards the rat rig - especially because they are EU based so I can avoid import tax

[avejst]

Great project
Obriter extruder!! V. 1.5 that is
Thanks for sharing your experience with all of us :-)

[haenselundgretel]

This video is soooo good! You give the perfect overview and motivation at the beginning. Perfect!

[jon]

A great video, and I have no doubt this is going to be an amazing printer, but my favorite part was seeing the Lowrider in action.

[RomanoPRODUCTION]

Thanks Michael for the Ayrton Senna cloth. I watch you at speed x2 like Senna and it's awesome ❤️

[darkozver]

You have been of great help with your content. Thank you very much and best greetings from Ingolstadt (Germany).

[torymiddlebrooks]

Just a perfect example of what we look for in a project. Including all the extra work to get the extras done.

[emanuelcalderon]

I love your videos. It has showed me how to start building a new machine. I will probably get one of this in the future. I used a ender 5 pro and have installed the lerdge k board with direct drive and alot of other features. So thank you.

My grandfather always said to use the right tool for the job. The Chop was clearly the right choice 👍
