FIRST LOOK - RatRig V-CORE 4 at RMRRF 2024

[@Nurgelrot]

Great vid. Looks like a major update the Vcore. Thanks for going to RMRRF and making these great videos for all us armchair printer geeks.

[@RJRiemensnider]

This will be my next printer

That is a damn fine printer!

[@jamesdmc2928]

I pre-ordered the 500. Excited to upgrade it to the idex

[@woodwaker1]

I had a 500 VCore 4 in my early bird cart, but waited until I could see one in action. Now it is gone, but am glad to see your video. I have a 500 and a 400 Vcore 3 and what I can see there will be no way to upgrade them to the Vcore 4 - everything has changed. It looks like they addressed all of the weaknesses in the 3 and made the changes in the 4. Looks like a good machine, I agree that the BTT Kraken would be a good replacement for the Octopus for just a little extra. It would be a good option and should be included in the new version of RatOS

[@therick0996]

Those Y-assist motors are intriguing

[@TechieNI]

These printers always look bloody awesome. This one is no exception.

[@mciarlillo1309]

Absolutely awesome content, thanks Nero! I’m super excited to get my early bird 500mm hybrid kit delivered and I can’t wait for the IDEX kit to be officially released.

[@ScytheNoire]

V-Core 4 looks great. Love the advancements.

[@WhereNerdyisCool]

I’ve read about the Nevermore devices but haven’t seen any real data on how effective they are ? Like actual particle measure testing on how effective they are. Looks like a great machine

[@CarloVaccariPlus]

It's for VOCs, not particulates.

[@Jim_One-wl4ke]

Looks cool, already have 4 printers 😂 still can’t resist it’s awesomeness ❤.

[@WhiteWulfe]

Definitely liking the upgrades they've brought to the table. Sure hope one can get panels with the kits this go-around, as that was something there was a lot of contention about in the past.

[@miklschmidt]

They're still not shipping the panels, those are self sourced. Reason being it's a shipping nightmare. HOWEVER! Panels are now rectangular and just needs a few holes drilled with a jig, so much cheaper and easy to self source locally!

[@AndrewduToit]

Just can't wait. And thanks for revealing a more or less date.

[@BeefIngot]

That V Core 4 is looking hot. I wonder what chamber temps it can hold reasonably, because while no tool changer, with that IDEX setup, I could see that being a really nice printer solution maybe slapping on an ercf for multi color and then your special material on the other extruder.

[@Eric_In_SF]

Was contemplating a Voron but…. Anyway, why not use eddy currents instead of a probe?

[@V1N_574]

Me too but I want those 500mm 😂. Also beacon I believe is very similar to eddy.

[@billverine765]

Great video and you asked all the right questions. The 500 MM version is calling my name, I can hear it.... :)

[@3DWolfEngineering]

its soo awesome, definitely on my list of future 3d printers

[@vim55k]

It uses LDO HT motors (180c) (on the website). I hope that all the electronics is outside. Then maybe possible heated chamber like 80c-100c?

[@miklschmidt]

All electronics (except motors and potentially toolboard, obviously) are outside in the box presented in the video. You may want to skip the toolboard when going for 80-100C (or look for one made for those operating temperatures). You also want to upgrade to gates EPDM belts, otherwise you should be good to go :)

[@vim55k]

@@miklschmidt thanks. Ok, belts - good to know. The toolboard is what I was afraid of. What do you mean - skip it? Isn't it is in the toolhead?

[@miklschmidt]

@@vim55k The V-Core 4 is a highly modifiable DIY printer, you can do whatever you want with it. Toolboard or no toolboard, RatOS doesn't care, neither does the toolhead :)

[@vim55k]

@@miklschmidt thanks. Good to know. Is it even possible without the toolboard?? I liked that v4 fullfilles most of the wishes including that fast new probe. Would prefer to tinker less.

[@miklschmidt]

@@vim55k Oh yes, hybrid needs 8 drivers including the extruder, so works on an octopus, which coincidentally ships with the default kit :)

I want to go to there.

[@yonutz333]

Any idea on pricing? Especially on the idex version?

[@joehimes9898]

Sharp looking machine.

[@bozthescrewup410]

Definitely going to need the 500x500 version!! 😮

[@sausage5849]

Does that look like the build plate could be at lest 50mm wider?

[@CanuckCreator]

It could, easily BUT Then when your running IDEX, toolheads cant occupy the same space cus ya know....solid objects, so you still waste that portion of the bed. SO best to just not use a bed that large and spec a bed thats both toolheads can utilize (same reason theres free room at the back for the nozzle alignment camera

[@V1N_574]

Why not a manta board?

[@mp-xt2rg]

Putting bigger rails on the z axis is like putting a class five hitch on a ford Maverick. Neat printer though.

[@MatheusFP104]

Waiting for the release of CAD files to me outsource in Brazil!!! Already have a vcore 3.1

[@getcass]

looks like a cracking machine

[@kevinaub]

Does that mean it's AWD now? Why does he say that the quad motors help only Y acceleration? Not X too?

[@ThomasS17]

It's not really AWD, as the extra motors just apply to the Y axis. From my understanding, it's basically a second motion system only moving the Y axis added on top. Since the Y axis has to move the whole X gantry, it can't accelerate as fast as X. The extra motors for Y should bring its acceleration closer to X and use more of the potential.

[@kevinaub]

@@ThomasS17 Yes that's quite a refreshing approach. I hope Nero does a technical breakdown of this and explain how effective this additional speed can be, maybe as compared to an AWD system

[@SirLANsalot]

500x500 sounds like a massive machine.....I want one.

[@PoopyPops652]

very nice video, very informative first look at the V-core 4 also nice Rat Rig hat. Voron hat when?

[@arvidjedlicka6237]

Anyone know if it uses the EVA carriage assembly? It looks like it but wanted to confirm.

[@MitsumaYT]

No it does not. It uses the RatRig Toolhead. There was already a beta for that for 3.1. VC4 uses a changed version (that still shares the same base plate of the 3.1 beta toolhead)

[@swankymanatee6968]

I got my eye on ratrig, Im not sure if I'm going to get one juat yet. I got distracted by the 2 "nerf" blasters in the other booth in the background. Looks like an orion lynx and a Captain slug caliburn. It's hard to tell, though.

[@vim55k]

The spec on the website - it is just maxed out!

[@riba2233]

still no chamber heater as standard...

[@CanuckCreator]

Most of these types of printers are enclosed well enough where you putting out enough heat from a mains bed to get the chamber plenty warm enough to print anything but the higher end engineering plastics like PEEK/PEKK/ULTEM etc an additional chamber heater isnt really needed for the majority of use cases

[@riba2233]

@@CanuckCreator ok, thanks for the answer!

[@CanuckCreator]

You see them sold as a feature on some off the shelf printers like Bambu and Qidi machines. But those are mostly to make up for the fact the printer enclosures are quite thin and full of holes so they leak a ton of heat

[@riba2233]

@@CanuckCreator true. I guess I would like to see both highly insulated chambers and the active heater :D that is what I'm currently doing with my machine, hopefully it will work well.

[@MitsumaYT]

​@@riba2233 In addition to what he just wrote. VC3/4 also uses mains powered bed heaters, 600W/1000W/1500W for the 3 sizes. Thats really a lot of heat you get passively vs the often 24V beds that some of those printers with active heaters have. And yes, the VC4 is sealed pretty well, helps to easily have chamber temps for ABS etc.

[@Dead_Aim556]

Cost?

[@woodwaker1]

I had the early bird special in my cart a 500 cube with almost all of the options and it was right at $2000 from the American store. I did not pull the trigger and is now out of stock, I waited too long, but wanted to see a video of it in action.

[@LincolnWorld]

I wish LDO or someone would offer these prebuilt as well as the kit. I would love one of these, but I do not have the time to build it.

[@miklschmidt]

There are a few retailers that will build one for you. I believe Portachiavi in Spain offer such a service.

[@ZeeLobby]

Fabreeko too. I think even RatRig themselves will build one. Obviously all come with a price tag

[@imre4481]

Does anybody have info on the plastics used in the chamber? Is it petg or abs/asa?

@@CanuckCreator Very NICE!

[@53Aries]

I'm not sure how i feel about the hybrid system. I love the concept but... belt tension. Corexy accuracy is already easily effected by belt tension. Adding the y axis helper system only creates more opportunities for belt tension to cause issues. I give this squinty eyes for now, just have to see what users report.

[@A13tech]

price ? are we talking in thousands or hundreds...

[@SentientTeapot2444]

Likely in between; 1200 to 1500 euros would be my guess.

[@eternity1243]

1900

[@tHaH4x0r]

@@SentientTeapot2444 Early bird price was higher than that iirc. I think the base 400mm was about 1600.

[@MitsumaYT]

A 500 size machine was ~2000USD shipped. Depends a lot on what you pick (CoreXY, Hybrid, IDEX) and what you might already have. ~1200 to 2000€ from 300 size to 500 size

[@phasesecuritytechnology6573]

Early bird price for a 400 with basic options like a pi was $1800

[@adamfilipowicz9260]

Also leaves room for the spool too and the nozzle wipers

Yet another reason why Voron should give up on the Phoenix 😅

[@CanuckCreator]

nah

[@HelgeKeck]

we need both printers, one is pushing the other

[@miklschmidt]

Like Helge said, when we saw what the Voron boys were cooking it just motivated us even more, i'm sure it works both ways. Very curious about what you guys are gonna do as far as software goes @CanuckCreator. Helge and me have been working on solving and working around all the inherent issues in the klipper IDEX implementation, slicing, macros, calibration etc etc. It wasn't easy, but we're both very proud of the result!

[@MrKennykyle1]

it's great but kinda pricey

[@IvanGOrtolan]

This printers are becoming just too expensive, 1600€ for a kit? Not worth it imho, there are plenty of commercial printers at that price point that do 99% of what this one does

[@CanuckCreator]

[@rust_game_shop]

I don’t like it. 3x was better with back electronics and stepper motor’s outside the box

[@juandoe-lq4wu]

Electronics are still in the back (outside printer enclosure) and the Electronics enclosure is included in the kit. Stepper motors are still outside, at the bottom bellow the steel plate (plate is included in the kit) The stepper motors, that you see inside are Nema 17 HT - that are specifically designed to work in a High Temperature environment!
