K3 build log, maybe ill remember to keep it updated, probably not though

sturdy pawn
#

wait youre also building a K3?

ancient wadi
#

yep lol

sturdy pawn
#

wasnt the vc4, vt, v2.4, V0, micron enough😂

ancient wadi
#

started sourcing about the same time as threadlicker

sturdy pawn
#

and more probably

ancient wadi
#

||many more...||

#

and no, its never enough

sturdy pawn
#

what was the most fun build so far?

ancient wadi
#

thats a hard one

#

i really like the v0s, they are really nice 1 day builds that dont have you constantly flipping a 30+kg box all the time

#

positron was geat, obviously

#

they were all really fun though

#

my BOM

#

PEKK-A-CHUBEEEEE (K3)

hence the name

Works surprisingly well on a voron

#

Oi, @prime reef , feel threatened

prime reef
#

Besides pekkachu doesn't ring as nice

ancient wadi
#

so it doesnt come close to what you did

You should try it

It got upgraded

prime reef
ancient wadi
#

what makes each of them so good

prime reef
#

MG94 because it's literally perfect in every way for ABS

#

Strong, great interlayer adhesion, easy to print (as far as ABS's go), amazing surface finish

ancient wadi
#

wow the HTN-CF25 isnt even hard to print

prime reef
#

King of ABS's

ancient wadi
#

you could do it on a voron no problem

prime reef
#

HTN-CF25 because it's a fuckin godly filament in practically every mechanical property

#

Like, I'm not sure how familiar you are with tensile strength and modulus numbers, but HTN-CF25 achieves 148MPa tensile strength and 16GPa tensile modulus in the axial directions

#

That's nuts

#

It's twice as stiff as the next stiffest filament I'm aware of

#

And like 50% stronger in tensile strength as well

ancient wadi
#

i mean at one point i knew how to calculate those numbers but i have no intuition for what exact values mean

prime reef
#

Well, to give you a frame of reference, ABS is typically around 35MPa tensile strength and 2GPa modulus

#

I don't remember PEKK-A off the top of my head let me check

ancient wadi
#

im not printing pekk-a for the mechanical properties lol

#

im printing it so i can call my printer pekk-a-chube

prime reef
#

PEKK-A is 105MPa strength and 2.75GPa modulus

#

Damn, that's already impressive

#

But still, HTN-CF25 is 148MPa and 16GPa

fluid moon
#

PLA in the most optimal conditions can reach tensile modulus of 4 GPa, 16 GPa is insane for a printable plastic

ancient wadi
#

maybe ill try some at some point

#

it isnt cheap though...

prime reef
#

I've never seen straight printed PLA above 3GPa

ancient wadi
#

170 euro for 750g, thats over double pccf

prime reef
ancient wadi
#

and over budget

The highest Young’s modulus at the value of 4.42 GPa was obtained with a slight deviation under other samples exposed at the temperature of 70 °C and 80 °C.

In conclusion, post-heat treatment has minimal effect on the Young’s modulus of 3D printed PLA but it was largely effecting the fracture limit of the structure.

I see

ancient wadi
#

Frame is done, not as big as I expected

vale hornet
#

Frame is deceptively small

ancient wadi
#

ye i was thinking that lol

#

but i have the panels so i know better

kindred arrow
#

Cant afford that

ancient wadi
#

i have been chubed

just need evri to deliver my accent filament and i can actually continue

#

also turns out i have a 110v bed

#

so i need to get a new one

split walrus
#

just found this post

ancient wadi
#

yep, it exists lol

ancient wadi
#

That's alot of rails

#

My rails are still on the way

#

Will prob buy the rest of the motion system next week and the enclosure+ filament so I can get to Printing

ancient wadi
#

yay nice

split walrus
#

Yeah got a friend with an x1c so he will print the PC for me

vale hornet
#

do your rails feel crunchy at all?

#

my HB rails felt pretty inconsistent and I was getting print artifacts until I swapped them out

ancient wadi
#

dont tell me that....

#

then feel fine i think.... ill stick with them for now and swap out later if/when i need to

ancient wadi
#

i have my doubts....

ancient wadi
vale hornet
#

wait bottom left is wrong

#

like this

#

because sidepack

#

if backpack, then I would do the first one

split walrus
ancient wadi
vale hornet
#

if you do the first orientation with sidepack, then you end up with the bottom left motor's wire running across the front

#

I do the second orientation to avoid seeing wires in the front

ancient wadi
#

ahhhh good point, thanks

vale hornet
#

may need to change your rail mounting if the roll in nuts interfere

ancient wadi
#

No, they dont

#

But idk what I'm supposed to do about it, they just don't fit, nuts have nothing to do with it

vale hornet
#

oh no not that

#

I mean the XY towers

#

for the bearings/pulleys/idlers

ancient wadi
#

Ohhhh I see

#

All lines up perfectly

#

The manual shows an orientation of the nuts that works

vale hornet
#

oh okay nice

ancient wadi
#

Ty for the reminder to check though

split walrus
#

When first print?

ancient wadi
#

Hot for another week at least

#

Still waiting for new bed and belts to arrive

split walrus
#

Ah from provok?

ancient wadi
#

Bed from provok, belts from ali

#

Oh and I need to sort out my k3rabiner

split walrus
#

My k3rabiner arrives tomorrow... Well I hope 🤣

ancient wadi
#

Nice, mine is still on its way from fabreeko to the guy I bought the kit from

ancient wadi
#

XY drives are in

#

can i use sensorless homing? rn the carriages hit the pulleys/idlers when its at max or min

vale hornet
#

You can only use sensorless homing

#

Did you forget to put the rail stop pieces in?

ancient wadi
vale hornet
#

I don’t like that order

#

My hex keys don’t fit if I don’t install the endstops first vaulthah

#

But yeah once those are in, the carriages won’t hit the pulleys anymore

ancient wadi
#

So there are endstops and you don't use senseorless?

vale hornet
#

They’re called endstops

#

But there are no switches

#

They’re just places for the carriages to stop during homing

ancient wadi
#

Oh OK, that's misleading lol

#

Thanks for clearing it up

ancient wadi
#

where can i find the printed parts for the chube toolhead?

split walrus
#

Isn't that just a dragon mount?

ancient wadi

idk, im using different fans too

great tysm

#

idk how you are supposed to find those things if you dont already know where they are lol

vale hornet
#

Good question vaulthah

#

It definitely isn't easy to find

#

I only know cuz I get directly pinged

ancient wadi
#

Very thick bed
