Ultra Zero G Pro (8WD, Watercooled, Hydra, 9mm Belts, 54V, 2:46.42 Benchy)

[dense elbow]

After vs before

Still some tidying up to do but so much happier with it.

[deft egret]

Much better

[dense elbow]

I love the backpack honestly

Even for just the power supplies alone

[deft egret]

Its more organised

[dense elbow]

Can't wait for the panels too

Going to look so clean

[obtuse field]

It really is. I still kind of want to do the backpack and those connectors but I really want to get it up and running so I may do all that later or at least those connectors 🤔

[dense elbow]

Half the fun is rebuilding it

Soooooo

Had to order new gt3 9mm for it

Soon as they get here I'll swapem

I also was able to fix my honey badger motor, I think. Going to see how it goes.

Oh also my new plan for water cooling is an end plate, and 3 40x40 cooling blocks for each motor. Those are gonna be ice cold. So unbelievably overkill. Perfect for me.

Wanted to get the printer up and running so I can print test parts in PLA and fast. I can't print less than 300mm and 25k acceleration now. It looks SO SLOW. lol old printer is like plz sir, spare me.

[dawn patio]

actually super interested in seeing how those blocks go, I am absolutely doing that if they work

[obtuse field]

True I can just wait and add them later

[obtuse field]

I may need to get your slicer profile whenever I get mine going. 🤣

[dawn patio]

so what I really want to see is it enclosed and in heated enclosure, because ultimately that was my plan just not with AWD yet so Im invested to see how the waterblocks go and how much cooler they run because it could work for my use case

I managed to source 2 LDO-42STH48-2504AH(S8-55) so even though they're the high temp models I can imagine they still run just as hot

[obtuse field]

Yeah the high temp rating just means they can withstand higher temps overall so 130c but they still run the same temps as far as running power to them if that makes sense

[dense elbow]

That's my exact plan!

https://a.co/d/11oQQqA

Check this thing out

[dense elbow]

It ruins other printers. Now anything more than a 15 min benchy I'm like man that's slow

[obtuse field]

I figured it will 🤣. I have a feeling this is gonna be my go to printer for everything and maybe a small parts printer. The other ones will be for orders and things that I’m not impatient for.

May honestly just throw it in the Creality tent I have for cheap enclosure until I get around to building an enclosure for it

[dense elbow]

Ignore the shaky table but I just love this thing so much

Ugh why does it keep ruining the colors

Ohhhh HDR

I think next big mod after water-cooling and everything is good to be an ecrf for this one

[obtuse field]

Mines gonna be on some garage shelving but I wonder if I should just leave it on the floor 🤣

[dense elbow]

I normally do it on the floor

[obtuse field]

Look at tradrack 14 channel mmu and its only like $150

[dense elbow]

Much be that way

Bro what

[obtuse field]

Yeah I’m debating on just making it permanently live on the floor but I gotta find a spot easy to get to

Yeah the kit

One sec

https://trianglelab.net/products/14-channels-mmu?VariantsId=11558

Sorry $115

[dense elbow]

You son of a bitch

[obtuse field]

My bad 🤣. I was debating it for mine or doing toolchanger eventually but I may give that one a shot since it’s not crazy expensive and I can use it on my other machines

I have a mosaic palette 3 pro but it’s pretty much a paperweight at this point 🤣

[obtuse field]

I’m hoping normal printing I can leave it on the shelf with the sv08 and then for speed runs throw it on the floor. May have to add some weight to the bottom of the shelves or more printers on the bottom 🤣

[dense elbow]

I mean look at this 8 min benchy in petg

Needs some tweaks after the rebuild but like

[obtuse field]

Yeah that’s insane. I have a big statue I need to print for someone and I already know it’s gonna be so much faster than any of my other printers so I’m waiting to use this one. Also I need the full z height 🤣.

Do you use orca? I could just copy those settings and it’d be perfect

[dense elbow]

Yee

When you're ready I can send my configs over, they'll need some tweaks but should be close

My printer.cfg is 600 lines now lmao

May need to split it out some more

[dawn patio]

Perfect! It's on Ali too
https://a.aliexpress.com/_m02ZPll

[obtuse field]

Okay dope I’ll reach out and let you know when I’m ready.

Yeah I’m gonna have fun with my config lol. I’m gonna split up all the macros and stuff to a separate file but doing the 8WD config I want to make sure I get all my pins assigned correctly and think of the best way to hook the motors up to the boards. Like a,a1, b,b1 or a,b then a1, b1

[dawn patio]

Do a box turtle

[dense elbow]

I do back left awd, front left awd, back right awd, front right awd, back left hybird, front left hybrid, back right hybird, front right hybrid. The first 4 on the kraken are beefier tho which is why I did that

[dense elbow]

THought about that one too

[obtuse field]

Cool I’ll probably do it that way as well. Thankfully all 8 are the same on the octopus pro and since I’m running two of them the pins will be the same so shouldn’t be too bad

[dawn patio]

Looks like you'd need a stepper at least though

[obtuse field]

Yeah I think 2 but I haven’t looked at the official bom. 14 channels is pretty cool though

[dense elbow]

I think I am gonna switch over to kalico too

[dawn patio]

It is hey, from what I could see the box turtle is the evolution of that, expensive but better

[obtuse field]

Any specific reason? I’ve been needing to look into it

[dense elbow]

https://docs.kalico.gg/Danger_Features.html
https://docs.kalico.gg/Bleeding_Edge.html

Just been reading through those

Interested in the new smooth input shaper and PA input shaping.

[obtuse field]

Yeah it looks really nice. After having 2 p1s’s with ams’s I’m kinda over all the purging and waste. I’m leaning towards toolchangers for my next upgrades/builds but who knows maybe tradrack or box turtle could be fun

[dense elbow]

[mcu] is_non_critical enables marking of an mcu as optional - it can be freely disconnected and connected at will. (useful for MCU-based accelerometer boards, mcu-based probes that shut down in hot chambers, etc...)
would be really nice for the beacon, randomly it gets upset mid print

Since it's only used for Z could be nice

[obtuse field]

Oh that’s sick and I think you could also define acceleration per axis so 100k y 150k x or whatever if they’re different

[dense elbow]

[temperature_fan] control: curve lets you set a fan curve instead of linear control oooooooooooo

That would be so nice

[obtuse field]

Yeah that would be really nice

[dense elbow]

I can do that for the fans on the rad

[obtuse field]

It’s just pointing to their fork right or do you have to reflash boards and all that

[dense elbow]

Looking into that now

Because I WANT

[obtuse field]

I may just start with that. I already have my pi configured and set up with klipper so I can just point it before I start working on my config and flashing my boards

It’s nice cause I can use the same firmware.bin for both boards lol

[dense elbow]

Yeah you gotta reflash everything

[obtuse field]

Okay cool I’ll just do that from the beginning then

I may swap over my other printers to it too after I mess with it more

Are you gonna do bleeding edge or main branch?

[dense elbow]

not sure yet

prob bleeding edge

[obtuse field]

Yeah it’s not like you have to enable all the bleeding edge features just because they’re available now

[dawn patio]

What do you guys reckon out of these 2 corner brackets?

[obtuse field]

I think either one of them should work. Probably these since it has support all the way across instead of the single flat backplate

[dense elbow]

Yeah I run those

Uber strong

I tried to sit on my printer to see if I could get it to flex. Nothing

I run those on each inside corner, and then corner plates on the outside

With the backpack now it's insane

[obtuse field]

I need to add the inner ones to mine but that can happen later it’s solid right now

[dense elbow]

found this for .99 at home depot, best thing ever for cleaning the bed

[obtuse field]

I need to go grab one. I’m just using the tiny Bambu scrapers lol

[thorn crown]

that also will give you better results.

these things will give you super good results too, and are the most common

[dense elbow]

Can't have enough bracing

[obtuse field]

I really need to get some but I’d have to buy 2 sets so almost $50 😭. I’ll get those when I do the connectors lol

[dense elbow]

Kalico installed

Everything ported, just had to reflash everything, and then reinstall all the plugins

Oh and a few config changes, but not bad at all

Flashing is all done via the pi so it's quick

[olive oracle]

I made one of those with spare parts lying around from the merc build. prbably it wil cost much less than 100$, mine costed around 50. I did 5 lanes, it uses a 100mm rail and a 150 t-slot (so to give you a visual of the size)

[obtuse field]

Oh that's not bad at all. I know I have spare motors from past builds I could use. Does it work well? Do you just have it use a purge block during prints. I haven't looked too much into it.

[dense elbow]

I could build it into the backpack!

Ooooooo

[olive oracle]

honestly, it's a bit of a rabbit hole the whole mmu, you'd need a filament cutter and a purge bucket, but the best use I do it's just to swap spool without needing to go down and actually unload and load myself. Plus, it uses the tradrack extruder together the sherpa mini, so there is no possible filament path that can bother that system, if the spool get tangled, the all thing get pulled over the printer 😂 . So it also improves the print quality in some sense, making a very easy life for the toolhead extruder. But you'll need a filament sensor on the toolhead as well, and a extrusion buffer (so if one of the two extruder is out of sync the buffer orchestrate the thing). I started with the tradrack and just a sensor on the extruder, so it can be minimal, but it build up 😅

[olive oracle]

posibly yes, it's a tiny thing, let me fetch a picture...

[dense elbow]

Have you seen this thread. Rabbit holes r us

[obtuse field]

Oh god 🤣. Yeah maybe if I went with the orbiter with the inline filament sensor 🤔. I could add that with one of my other printers or swap out the vz-hextrudort.

Purge bucket and nozzle wipe shouldn’t be an issue I have a little bit of space on my plus.

[olive oracle]

this is an old image, you can see I recycled the Y double shaft motor 😂

on top of a filament spool

[obtuse field]

Now I need it 🤣. It’d fit perfectly mounted here.

[dense elbow]

Look at those recommend numbers

Lmao

Need to figure out what's going on with x

[obtuse field]

43k for y is awesome

Well it has 4 less motors than y lol

I wonder how much setting them separately in the config would change

[dense elbow]

I broke something

lol

Not sure what

[obtuse field]

Rip hopefully nothing crazy

[dense elbow]

hehehehehehe

[obtuse field]

Glad I got 4 of current one. Then I can get 4 with the temp sensors when they drop 😎

[dense elbow]

Installing these on all motors

Going to give a shot

Last part will be here tomorrow morning and then full water cooling babyyyy

[brittle cedar]

That is gonna be crazy. With that many barbed water connections i would get a box of spring style hose clamps. They re-tighten as this settle from vibration.

[dawn patio]

Definitely doing the same if it works

[obtuse field]

What color liquid are you gonna use or go colorless?

[dense elbow]

Yeah, good call!

[dawn patio]

DREMC is going to stock the classifieds here in Aus!

So happy

[dense elbow]

Whelp it's gonna look hella jank but it should work

I see why they went with tiny hoses and just the end plates

Looping these together is a pain in the ass

[dense elbow]

Update

That's not gonna work

It only pushed fluid through the first two motors, so I'd need a wayyyyy stronger pump, or redo the manifold system

500l/m isn't enough

[obtuse field]

8 pumps one for each motor 👀

[dense elbow]

Hmmm

[obtuse field]

How much are the pumps?

Maybe a fish tank pump? I know those can do a lot but not sure how compact they are

[dense elbow]

25

[obtuse field]

if it’s only doing 2 motors you’d probably need at least 4, would you be able to mount 3 other ones? I wonder if you’d have to do 4 separate loops instead of one continuous one

https://www.amazon.com/VIVOSUN-Submersible-Fountain-Aquarium-Hydroponics/dp/B07L54HB83/ref=mp_s_a_1_3?crid=185E75MKACIOI&dib=eyJ2IjoiMSJ9.GRXS_DE1-2qqAk8_M2IOHnFGP30EDDVBRb4yzYn7I-UgeTklrXtomU9BlIU2Xyrbv1SGNH_nou38jO4rWjurMcDtdb7OnQ0dqyvmbIh4zKlZNdNJgibfemaG1FMfEjWCD392xzxQWumPj6SfolQf0Zx-OxIlMWhg-xce6B3sz9EGc5hE-f42QbUzSjNf0ykwl9xH59PzwM6CnukcjHmXSw.be19vHvocrxm-N51Ltrq7Gbi9s0Lq-GqhJ9VgU0RW1E&dib_tag=se&keywords=fish+tank+pump&qid=1736381077&sprefix=fish+tank+pump%2Caps%2C142&sr=8-3

[dense elbow]

https://a.co/d/iQgjS8I

This might blow the fittings off lol

[dawn patio]

Look for a big pc loop pump

Not sure what spec the combo one is but a good d5 could do better

[dense elbow]

Looking at server cooling setups

for 8 gpu's

https://koolance.com/pump-g-1-4-bsp-pmp-600

They say thins thing

https://a.co/d/3O6rbba Going with this one

[dense elbow]

So I changed my mind

Because I worked out the math and the that is going to be starving, so I am opting for 2 of these 800L / H

[obtuse field]

Hell yeah aquarium pumps are solid 😎. Plus those are cheaper

Worst case the one I sent was 800g/HR or 3000L/H which is crazy lol

[dense elbow]

Yeah lol

Submersible wont work tho

Since it dosen't hgave an inlet

[obtuse field]

Oh yeah didn’t realize that lol

[dawn patio]

Hmm, wouldn't some pumps have the whole pressure vs volume issue like fans have with Cfm and static pressure?

Ahh, I see it now, that one has 5m vs a D5 has 3.7, so I guess it's an ok increase

As far as I remember on of the reasons why loops often don't use aquarium pumps even though they're higher flow is they often don't have enough head pressure to push as they aren't often designed to pump against much resistance

Koolance do the big Bois with a lot higher head pressure for big loops/higher pressure reqs, they're a little more expensive but designed for it
https://koolance.com/pumps-individual-stand-alone

And they can be run often on 12 OR 24V

[dense elbow]

I think I had a ton of air lock too, I got valves so I can bleed each loop

[dense elbow]

We're water cooooooled

Well half of it

Still need the bottom motors

[dense elbow]

Ultra Zero G Pro (8WD, Watercooled, Hydra, 9mm Belts, 54V)

I might need to start a new post with the actual build instead of miles of reading lol

Once I'm done tho

[muted nova]

This is insanity 😂😂😂

[dawn patio]

What pump did you end up using?

[brittle cedar]

Can confirm, used to use two PMP450 to watercool 10 servers. They are beasts.

[brittle cedar]

Looks amazing. 😍

[dense elbow]

@dawn patio

[dense elbow]

I started out with 6x4mm, then got the lil cooling blocks, and was like well I can fit three and still put the acrylic panels on, and now everything is 10x8mm, with the mains being 3/8x1/2in. It definitely escalated quickly lol

I could still slap on the back cooling blocks but I have a feeling this should be more than enough cooling 😂

Still have a few ideas to really clean up the hoses, also need to figure out where I'm going to stuff double the amount to add the lower hybrid motors....

[dense elbow]

Unbelievable performance

Well actually pretty believable with everything lol

[obtuse field]

That looks so good!

[thorn crown]

those extrusions at the front might cause some resonances you dont want 👀

[dense elbow]

@thorn crown for sure, need to add the front pieces, had to leave them off until I got a new tap

Whoops meant the picture

I should run input shaper, bet they act like tuning forks rn

[dawn patio]

https://uniqueprints.shop/shop/bondtech/reverse-extruder-set-sherpa-hevort/?srsltid=AfmBOorSvyeRD_4n5EFLVyi3oe0RnCNsjBvAUxgKeMj5XnUjmlxYgguS

I wonder if this would be an improvement, I want to try it for the hex but its for sherpa too

[muted nova]

@dawn patio are you running a printed Hextrudort? The cnc ones from Mellow already have that.

[thorn crown]

maybe lgx lite?

[dawn patio]

Oh shit! No way, yeah I am, that's awesome

[muted nova]

yeah, its mellows version obviously but its the same thing. Cnc machnined integrated.

[dawn patio]

Awesome

[thorn crown]

@dense elbow how much did ur watercooling setup cost?

[dense elbow]

Err prob like 1k

Would have to check, bought a lot and returned alot changing design directions

[obtuse field]

I wonder if it’d cost more to watercool the plus 🤔

Although for another 1K I could start my beta build 👀

[dense elbow]

Everything is officially water cooled

Including the extruder and extruder stepper motor

[tender belfry]

how did you even manage to put the endstop on the right side

[thorn crown]

just on watercooling??

[dense elbow]

yeah for everything, including the watercooled hex, stepper motor heatsinks, tubning, coolant, pumps, rad, fans, etc.

[dense elbow]

Made a custom mount for it

[tender belfry]

ah I see

[dense elbow]

Fits the curve of the pancake and uses the Uber long screw that bolts the heatsink to the extruder

[dense elbow]

@deft egret I can hit 1250mm/s with 150k accel now, which is scary

Watching that thing just FLYING

[dawn patio]

@dense elbow did you change back to the hgx?

[obtuse field]

8 classifieds at 2.5A? 👀 that’s insane 🤣

[deft egret]

Dayum

[dense elbow]

Switched to a 10T motor and getting decent results, ordered the hex plus WC

[dawn patio]

Similar to hgx?

For results that is, Il keep it if it's good

[dense elbow]

Still disapointed with it tbh, I think the plus with a 10t will be good

I have to stick with a vz water cooled or I need to install the whoile heatbreak and everything again on the goliath

[dawn patio]

Oh yeah true! Shit, that's a pain

https://youtu.be/hcMxEkVvIdE

I just saw this

[dense elbow]

Latest update is working on this

Only 40 more tests to go

Each one takes about 5-10min and uses 5g so not too bad but very time consuming

[obtuse field]

Not bad at all. Hope you get good results from it!

[dense elbow]

Basically it should have the ideal PA value for any combo of accel and speed from 100-800mm/s and 1k-50k

This is just for this filament though, hopefully it dosen't change too much between different filaments

Would prob have to do for each type tho, pla,petg,asa,etc

[obtuse field]

Dang that’s a lot of tests. yeah probably for each filament type

Hopefully the results are worth it then I’ll probably tune mine for it.

[dawn patio]

Also, wtf do I do with a 300mm bed? I got one for free and don't want to do a voron

[dense elbow]

The 250?

I think it uses about that size

That's the printer name, if you're not familiar

[dawn patio]

The t250?

[dense elbow]

Yeah

[obtuse field]

Does the t250 use a 300mm bed. I thought it was smaller 🤔

[dense elbow]

I keep posting to @obtuse field lol, Found a much better way to tune adaptive PA

Using the kalico bleeding edge PA test

This does 3 different speed zones, so one tower per accel you want to tune

So far seeing much more accurate results, plus it bypasses everything since its in the firmware and not slicer

Will post results after finishing up tuning

[obtuse field]

Ayeee awesome may have to do that method

[dawn patio]

Your next printer?
https://ston-3d.com/products/ston-wolf-batch-2

[obtuse field]

That looks crazy

[thorn crown]

oh goodness no. why.

[deft egret]

I like it, but I would do the h-bot motion system like the one on positron

[dawn patio]

Because fast

[dense elbow]

So my quality setting is still a 15min benchy that's flawless, not fast but also not slow. Pretty happy with it over all.

[thorn crown]

that cant be fast. almost all the motion system components are on the gantry

[dense elbow]

1500mm/sec travel speed at 30k accel (motors warm, not boiling).
• 300-600mm/sec print speed at 12-40k accel

Yeah def not fast

I mean quick, sure, fast? no

[dense elbow]

@obtuse field @deft egret Warning, don't upgrade to latest extended core-xy

Breaks homing

[deft egret]

Nice

[obtuse field]

Did you get it fixed?

Also are you doing 400mm bed with the new build? Will there be enough clearance for the hybrid front motors or is it not gonna be 8WD? Mine is suppper close idk how you’d fit a 400 bed unless the beta frame is bigger overall. If so I may go 400mm if I have to go hydra with the new frame too 🤔

[dawn patio]

I mean it's here and it fast, maybe not as fast as 1500 but still very fast
https://youtube.com/@ston-3d

[obtuse field]

That fan duct design is crazy cool. I like the unconventional design.

400mm @40k 😭 what I’m trying to get mine tuned to

[dense elbow]

Printed in 2 hours with my 15min benchy profile. Absolutely flawless

Maybe just a bit more overhang cooling

[obtuse field]

That looks amazing! I upped my cooling to like 70% and 80 for overhangs it helps a ton. I may run it like that but I gotta tweak it some more

[dense elbow]

2:53.29

I think this will be my official submission

Sure aint pretty, but it's a benchy

Damnit if I can kick another second it'll be 7th

Let me see what I can eo

[dense elbow]

2:46:41

6th place

[deft egret]

Dude what??

[dense elbow]

I officially made an entry

https://youtu.be/H5eLGl_kmNw?si=E7c8lqtLxmHNbMPg

2:46:41
985mm/s speed
115kmm/s acceleration
105 SCV

As for future plans, currently I am getting it fixed again, after I snapped a few things during those runs. Then working on the enclosure again for it

[thorn crown]

maybe switch to all metal for back towers and xy? 👀
imo, rigidy > lightweight and many motors

[dawn patio]

If you do that and get it working Il do it too lol, always wanted AWD metal

[thorn crown]

maybe not the front towers since theres no design, but for most cases, awd isnt necessary

[dawn patio]

But if case is, "go fast"

[thorn crown]

you can still do well with 2wd

imo, push out the most you can out of 2wd. it promots good engineering

[dense elbow]

I mean look at precurrsor

I chose violence over engineering haha

It's the true American way. Just add more horsepower

Lol

[thorn crown]

I dont mean offense to you, but I still see him as the face of ZeroG and the best mercury

[dense elbow]

Oh ive said that many times

Why I didn't take fastest nerc

On the official post I also said mercury inspired not mercury

I mean the only Merc part I have is the x joint which is upside down and Hydra.

So it's just not the same

I have infinite respect for him, what he has achieved is incredible

[thorn crown]

you should switch to all metal on your back towers and xy

it would greatly help Im sure

and double shear

[dense elbow]

Yeah, it's def on the list. Honestly I'm really happy with where it's at rn though. I'm going to enclose it and then just print for a while on it. It's only printed benchies lol

[dense elbow]

Everything is currently double shear tho

[dawn patio]

@dense elbow would you consider selling the steppers you have if you're getting the new batch of classifieds with thermistors?

[dense elbow]

Probably not unfortunately, as going to be using them for other builds.

[dawn patio]

Latest update on the Merc, I have been working on the enclosure for it. Haven't had a ton of free time unfortunately though.

[spiral beacon]

@tranquil fog Here's the insanity

[tranquil fog]

okay thanks

[dense elbow]

Ayyy lol
