Quantumania

[sharp furnace]

We’re doing these first for no particular reason

Well no there is a reason

I didn’t feel like cutting 12 tubes tonight

[sharp furnace]

only need to do 12 more (shorter) arms
But like, later

[sharp furnace]

Should I epoxy granite the extrusions? I’ve got the epoxy, all I’d need to grab is some sand

They’re all 2040s

Uprights are 400mm, diagonals are like… around that?

Diagonals are 370

Ok so that

Estimated at around 2.9kg of epoxy granite

That’s a noticeable amount I think

If I’m ever feeling funny I could use lead powder, would get like 10kg I think

Just uh not cheap

https://www.rotometals.com/reclaimed-lead-shot-1-bag-22-5-pounds/?

Nvm that’s kinda cheap

Wouldn’t be able to fit as much since it’s big

So like 7kg

Real lead powder would be 6 times the price or more

[sharp furnace]

I think the heaters shipped

Well

“Preparing package”

[sharp furnace]

Yerp

[sharp furnace]

Talk about build volume

[charred hare]

You got large hands is all

[sharp furnace]

need to look into countersinking the g10 bed

I doubt it’s super difficult

[sterile fractal]

should be fine

use countersinking bits and do it with water probably

[sharp furnace]

yeah

[limpid bay]

Sour patch kids?😂

[sharp furnace]

I love it

[viscid lotus]

Add a bed fan for faster bed cooling / chamber heating

[sharp furnace]

There’s currently no chamber because my part cooling inlets are outside of the build volume

I can also just blast the bed with the part cooling and it will cool it down even while the heaters at 100%

[sharp furnace]

I guess I could put the whole printer in a box

[sharp furnace]

Test carriage

[sterile fractal]

good shit

great design

[sharp furnace]

idk

it’s better than quantumania

but the double shear feels a bit lackluster

[sterile fractal]

no i really like it

whats this for

[sharp furnace]

we will see if it works

it’s just a test print to see if mpjets fit

because I have arms for this printer now

[sterile fractal]

ah ok

i too have arms, no printer tho

[sharp furnace]

lmao

I printed an effector but it was overextruded

[sterile fractal]

aw

on the e3 or on the p1p?

[sharp furnace]

p1p

ender is still dead

z axis is being goofy

I’ll try to fix it this weekend

maybe

[sterile fractal]

rip

[sharp furnace]

I countersunk the bed but just realized I don’t think I have countersunk m4

I’ll buy some

[sharp furnace]

update

the mpjets fit in the carriages

so I will print them using real filament

prolly pet cf

[sharp furnace]

It seems i forgot the adhesive

Or they weren’t able to do it

Not sure

I have thermal glue so it’s ok

They’re pretty nice

[charred hare]

sweet

[reef glacier]

they look cute

[blissful hull]

those are nice

[slate crown]

is this the printer with the two parallel stewart platforms?

[sharp furnace]

no, this is a quantum delta, which is essentially a normal delta but the bed moves instead of the hotend

https://youtu.be/mS2b9j2ok0M?si=_FZuhFzf5GSkmeH6

Like this

[slate crown]

oh 🙁 there must not be a project post for the thing im thinking of

[sharp furnace]

#1374618182761058395 perhaps? though I don’t think delta platforms technically count as Stewart platforms (do they?)

[slate crown]

oh yeah, tyvm 🙂

[slate crown]

very possible, i barely know what a stewart platform is lol

[sharp furnace]

Hi gang this isn’t dead either

It’s getting a new hotend design

Dual 80mm long 120w mains heater cartridges

Rather than quad supervolc

And halos

Will

Probably be bought soon ish

Need to suck it up and design PCBs so I can submit for oshwlab stars.

Then jlc pays for like

90%

[torpid sparrow]

https://tenor.com/view/look-at-the-size-of-that-thing-amazed-gif-10812416

[sterile fractal]

is this for rework

[sharp furnace]

so is the swirly twirly one in #1374618182761058395

[sterile fractal]

gooood shit

[modern adder]

80% of part cost + shipping

[sharp furnace]

I was close

[modern adder]

Yeah

[sharp furnace]

Thank god they pay for shipping now

[modern adder]

Last years was 100% of cost but no shipping

[sharp furnace]

Cuz halos are heavy

Yeah

[modern adder]

It's so much better now

[sharp furnace]

I was looking at s couple hundred in shipping

[modern adder]

I need to design 2 more pcbs for cuprite and actually finish up design

The scope creep is so real

[sharp furnace]

Dude it is

[modern adder]

if I didnt scope creep i could have just used the highway grant and built my printer a few months ago, but instead i spend months designing improvments

[vast ridge]

Are you making all of the parts?

[sharp furnace]

JLC probably will

Heatbreak is commercial

Everything else is custom

[vast ridge]

How much does it cost?

[modern adder]

where are your heater wires going?

[sharp furnace]

Not a clue, need to get real quotes for the options

Auto quote is nowhere near accurate for a milled meltzone

[modern adder]

according to wayne about supervolcano heaters the cables are pretty stiff and if you dont have enough clearance can actually heat up the heatsink more than the heatbreak does, but idk if its the same for your cartridges

[sharp furnace]

Just up and out the sides, the gap should be big enough. The hotend isn’t moving so I can get away with weirdness

I could make it bigger if needed of course

[modern adder]

yeah I feel like there isnt enough space rn

also are you doing bottom brace?

[sharp furnace]

The gap is just the size of the titanium section of the heatbreak

Any larger will have copper sticking out

I think it’s just the angle

[vast ridge]

damn 😔

[sharp furnace]

Yea, need to add it

[modern adder]

another thing wayne mentioned to me is braces in xy is going to be better for rigidity than vertical ones

[sharp furnace]

Either thin titanium clamped under the nozzle or I’ll add side holes

[sharp furnace]

Ya

I can brace it against the halo

[modern adder]

im redesigning my hotend completly to use a single mch heater instead of dual supervolcano cartridges bc of that

my hotend is now less than half as wide

and half the weight

[sharp furnace]

oh interesting

I really like your toolhead so far

[modern adder]

thanks

i got a ton of useful feedback recently so im working on implementing stuff, just school is throwing a lot of work at me

[sharp furnace]

real

[sterile fractal]

psst psst feel free to submit it to rework

wait are u an alum now i forget

[modern adder]

yeah im in college

still can do blueprint though

[sterile fractal]

and rework!!

[modern adder]

yeah some programs have different cutoffs

im just getting parts through jlc so id rather not make it a seperate order just to submit to rework

but i have ideas for mods, just dont have time to do everything

[sterile fractal]

fair tbh

[modern adder]

im probably not going to do infill

[slender vale]

@sharp furnace this is not the project for the one I mentioned before?

You don't have one?

[sharp furnace]

#1374618182761058395 has both hotend and bed moving, this one is just bed

[sharp furnace]

this may come as a surprise, but i worked on this project today

big WIP but the idea is to have a just like module thing that slides into the ammo can

the extra space around the power plug will hopefully be for breakout board connectors/cable harness throughput

i have a like 200cfm 120mm server fan so i am not worried at all about cooling really

will need to split it into parts for printing

but thats ok

[sharp furnace]

once again still wip but

there will be things bolted to the inside of the hinged panels

mostly breakout boards for clean cabling between the ebox and printer

(and ez quick disconnect for travel)

hinge makes servicing it super easy

[slender vale]

Pretty cool!

I have one of those ammo boxes

[sharp furnace]

I have some smaller ones but no 50cal ones which is what this is

Harbor freight sells them for like 10 bucks tho

[slender vale]

I have no idea what is what I have

But you cannot go and buy weapons or ammos, so they are probably replicas ig.. but it's very well made and airtight

[sharp furnace]

They’re probably functionally the same

[sharp furnace]

Should be significantly cheaper than any comparable commercial hotend

[sharp furnace]

Final quotes for both this printers hotend and my Enders hotend

Pretty cheap

[somber wave]

What material?

[sharp furnace]

these are alu

steel would be $15 ish more

brass similar price to steel

depends on geometry

the big hot end costs more than steel for brass

the little hot end costs less than steel for brass

“little”

[sharp furnace]

itll work

[quaint delta]

Wait no

Why did you put the thermistor there

[sharp furnace]

uhh

felt like a decent spot

[quaint delta]

you should put it as close to the nozzle as you can

[sharp furnace]

oh really? hmm

makes sense

i can do that

[somber wave]

On my hotend it is less than 2mm from the nozzle

[modern adder]

Did you already send it for manufacturing?

[sharp furnace]

no

[modern adder]

You should consider making it less wide at the bottom so ducts can get closer to the nozzle

[sharp furnace]

So about that

[modern adder]

oh yeah im slow

i forgot ur cooling

[sharp furnace]

lmao

[slender vale]

Super curious to see how it comes out

Giving me more fomo to start do mine

I dig that hotend

[sharp furnace]

me too

been working on trying to get halos

[slender vale]

What's that?

[sharp furnace]

the top/bottom thick metal panels

[somber wave]

just do AR500 lasercut and lap them

[sharp furnace]

expensive af and I need tapped holes

[somber wave]

IIRC it wasn't that expensive for small parts

and just tap the holes then

[sharp furnace]

they’re not small

[somber wave]

or get them to tap it

[sharp furnace]

they’re 300-350mm^2 ish

[sharp furnace]

you can’t do that

[sharp furnace]

they won’t do it

because it’s a fucking nightmare

the only option is thread milling and even that’s difficult, and I can’t do it

[somber wave]

yes you ca, but not with that attitude

[sharp furnace]

my taps are softer than ar500

I think

or pretty close

[somber wave]

get good taps and not shitty ones then

why do you even have taps that are that soft

[sharp furnace]

it’s gonna break taps

[sharp furnace]

I think it’s just close

I’m not tapping the like 20 holes in hardened steel

[somber wave]

it's not enen that bad

[sharp furnace]

that’s stupid

[somber wave]

55hrc

[sharp furnace]

it is that bad

[somber wave]

it really isn't

[sharp furnace]

there’s a reason people don’t tap it

regardless it’s not the right choice for this project at all

[somber wave]

I have tapped some 60hrc materials just fine

[summer dirge]

this is cool af, its like the minuteman but actually practical

[slate crown]

I would love to see this come to fruition! 🥲

Wish I could help!

Sending thoughts and prayers!

🥲

[sharp furnace]

I think I might be able to source the halos through jlccnc if I stop procrastinating on my distribution PCBs

[slate crown]

sick, i genuinely hope it comes to fruition

I love seeing projects come together 🙂

[sharp furnace]

Found some ebox connectors at school

Well I can use them for ebox

[signal vine]

you're welcome

[sharp furnace]

Hot end

[slate crown]

Normal hotend, just long?

or is it something special inside?

(screw, etc.)

[sharp furnace]

Nothing special inside really, most of the special geometries will just increase back pressure and reduce flow compared to loooong meltzone

It will, however, have dual mains heater cartridges

[summer dirge]

have you seen the roetz-end? imo this printer is designed perfectly for it

[sharp furnace]

I have. I do not want to deal with multiple spools of filament

This printer has a bed that is still big enough for a lot of the things I print regularly. I don’t want to have to deal with 4 spools of filament for every print, especially if it’s something more expensive for functional parts

I can’t afford that and don’t have the space 😅

[summer dirge]

i was thinking the other day that this would make one hell of an UHT

all the electronics including motors are outside so you can pretty much pump as much heat as you want inside the chamber if you enclose it, and the thermal mass on the hotend isnt limited at all

i might build one of these just for that when im in college for engineering materials

[sharp furnace]

Yup

I’ve thought about doing it

I looked into heating my part cooling for a while

I wouldn’t do a halo design the same way for ht because it just heats up like crazy

insulation halo lmao

[summer dirge]

Is the halo your cooling setup?

Not familiar with delta vocab

[sharp furnace]

The halos are the steel plates
Technically they’re not true halos but technically I don’t care

[proven gyro]

very fun

where are u submitting the build for this to btw, if you are submitting this to a YSWS

[slate crown]

What's a YSWS?

[sharp furnace]

nowhere

twas originally blueprint but that is long gone

[sharp furnace]

god i literally made a post about not calling it that outside of the community

we are part of a group called hackclub, an international organization of teens running programs for teens, aiming to get teens interested in tech

a ysws is a term for some (most) of those programs
it means
You Ship We Ship

you provide x, we provide y.
usually thats you provide a polished design with a journaled/tracked creation process, we provide funding

[slate crown]

Teens provide funding to other teens?

[sharp furnace]

We design and run the programs yeah

There’s a few adults involved of course
