Ender-Stinger

[tawny swallow]

I'll be starting Humperdoe's ender-stinger build; however, since it's discontinued, I plan on adding a bit to it in cad. This will be my first build, and I'm hoping to keep my budget within the $400 range. As of right now, the BOM is not finished, and I still need to go through the model's hardware to finish it. There's quite a bit of stuff that I need to buy, and I wont list all of the stuff, but some of the modifications that I will be doing is as follows:

• BTT Octopus v1.1
• BTT pi v1.2
• Belted Z
• AWD X and Y axis
• StepperOnline Nema17 42-48 2004s
• Stinger Toolhead
• Quickdraw Klicky Probe
• Linear rails (XY)
• LH Stinger AUX fan

I'll link the BOM when I get to it, but for now I'm going to bed. Thanks, Kevin and Kol for inspiring me to do my first printer build. It will probably take 4 - 10 months just for me to get all of the parts, but I'll do as much as I can in the meantime.

[tawny swallow]

Printing toolhead and belted z parts

I'll order all the stuff I need for belted z very soon.

[tawny swallow]

Toolhead (no hotend yet)

[strange cedar]

that's a nice finish

[sinful zephyr]

🔥

[tawny swallow]

More parts for both x and z axes

[tawny swallow]

Everything I should need for the belted z has been ordered

minus some screws which i'll get at a local hardware shop

[tawny swallow]

Also ordered 1 more 42-38

[tawny swallow]

Minor changes

[tawny swallow]

Z motor mount and tensioner

[strange cedar]

bottom transmission belted z?

[sinful zephyr]

ist that petgcf?

tjats not gonna hold up boss i dont think

[strange cedar]

my petg-cf belted z parts have held up just fine for 2 months now

[tawny swallow]

The only other material I have right now is some wet PLA

[tawny swallow]

2/3 of the belted z stuff just arrived

[tawny swallow]

the item that arrives last is the one i need the most

[tawny swallow]

Ordered the wrong bearings, but I can use them for my x and y axes thankfully.

[faint scroll]

are you doing all of this on one machine? like both printing and modding?

[tawny swallow]

I'm printing all of the parts on my ender 3 s1

Rods cut and bearings finally arrived

[tawny swallow]

Ordering linear rails

(finally)

[quaint ocean]

Man I totally missed that you had a project forum open

I’d have been in here for a while had I known

Those Z motors are looking 🔥

Maybe I need to do AWD X

[quaint ocean]

Oh damn that’s not a bad idea, some stability feet for Y axis

Forget stinger has those. Could make them adjustable or something, wouldn’t be hard

Though Kevin’s idea is to just add an entire extra extrusion, but that’s a good deal more work

Feet would require though that I remove the power supply on the back since it’s under the motor

[tawny swallow]

Was originally going to only use 1 x axis motor, but iirc Kevin said that was his motion system bottleneck.

[quaint ocean]

Yeah for sure. Y axis isn’t directly double the requirement of X so double motors on Y means you’re considerably overpowering Y compared to X. So far it seems like both kinda have their issues right now with 1 X 2 Y but it is what it is

I’d previously done 500/1mil/120 on Ellis speed test but it apparently crapped out on 500/200k/60 or whatever this was on LH speed test

But it was Y that crapped out so I have no idea what to believe right now

[tawny swallow]

planning to get the breakout board from the LH stinger. I'm also problably gonna buy the stinger cf heatbed to use in this build as well so hopefully I wont have too many Y-axis issues.

[tame orbit]

Hey i got the same stepper motors!

[tawny swallow]

I also use the same steppers on my s1 and they work very well

[tame orbit]

What accel ars you using and run current tho?

[tawny swallow]

I kept the current the same because these motors honestly get hotter than the originals

[tame orbit]

Yea i get that lol. 2004s on the way be here tmrw. Im excited

[tawny swallow]

Nice

[tawny swallow]

Top idlers printed, no more need for the velcro loop

I still need longer m5 screws for the other side unfortunately

[hollow halo]

[tawny swallow]

Totally relevant

[tawny swallow]

im planning on ordering ASA-CF and printing it unenclosed

since im aout of petg-cf

Any other cf suggestions?

[strange cedar]

tpu cf

[tawny swallow]

World's floppiest printer

[quaint ocean]

I think what you mean is “Compliant Mechanism”

[tawny swallow]

😭

[unique skiff]

PP-CF for lightweight fanducts

[tame orbit]

Polycarobonate cf?

PC-CF prints reccomended 280-310 prolly like 110 on the bed. But has a very high tG. Im thinking abiut movint to that for hotend stuff. My thinner ABS parts still start to warp in my Enc.

[tawny swallow]

Not sure I can print pc-cf without an enclosure

[sinful zephyr]

thats not real pccf

i print abs and asa at those temps

[strange cedar]

nope that's about right

maybe a little low

pc will punish you if your chamber's not hot though

[tame orbit]

Sorry fixed

[sinful zephyr]

yeah thats the issue

you need at the very very very minimum 90c

and usually 120c

[quaint ocean]

CF significantly reduced warping

Pure PC requires hotter chambers but PC-CF is manageable on typical enclosed printers

PA-CF and PC-CF are much easier than their non-filled counterparts

Lemur Haze had a video of printing PA-CF on the Stinger unenclosed with a draft shield and the parts look nice

Also the hotter chambers generally just make it easier. Larger parts are a much bigger issue but small stuff can be done pretty easily without high chamber temps since there’s nowhere near as much material to warp

[sinful zephyr]

it was prusa which afaik is a blend

when i did research on it

[quaint ocean]

Either way still the CF contributes significantly to making it easier to print

Since CF reduces warping

[sinful zephyr]

oh like glass filled?

ngl id still stick to abs or asa

[quaint ocean]

Both of them work for similar purpose

CF does improve thermal properties

But both are mainly used to control warping

[tawny swallow]

I'll probably print everything else out of asa-cf

[quaint ocean]

Ambrosia sells purple ASA-CF now

[sinful zephyr]

sick

[tawny swallow]

unenclosed

[sinful zephyr]

maybe petg will be fine unenclosed

ifk tho

[quaint ocean]

Um

Yeah

[sinful zephyr]

cardboard box

[quaint ocean]

That’s literally what PETG is made for

Is being able to be printed unenclosed

[sinful zephyr]

for printer parts its fine unenclosed

[tawny swallow]

Petg cf printed fantastic

[quaint ocean]

Though gets significantly stronger in an enclosure

[sinful zephyr]

if you are printing with petg parts enclosed they might get too soft

as in like the toolhead and belted z

[quaint ocean]

We’re talking different stuff

[sinful zephyr]

yea

[tawny swallow]

Screws are gonna take a while to arrive

I changed my mind on buying them from a local hardware shop after I saw the total cost

[quaint ocean]

Buying screws local is absolutely fucked. Like two M5 screws at Lowe’s is like $5

[sinful zephyr]

region dependant

[tawny swallow]

Thats worse than it is here

[sinful zephyr]

ik a guy who can get a kilo of screws for like 6 dollars

[tawny swallow]

All of the screws I needed would have cost above $55

[sinful zephyr]

but not me i will probably pay $5 for 2 m5s as well

[quaint ocean]

Not region dependent. Big company dependent

I said Lowe’s

[sinful zephyr]

well we dont have small hardware shops as much in NA as eu i believe

dont quote me on this

[quaint ocean]

Bruh I’m in US…

Lowe’s is a chain big-box store

[strange cedar]

this is probably worse in the US than other places

[sinful zephyr]

yes thats my point

[strange cedar]

b/c imperial is standard

at my local home depot the metric fasteners are confined to one drawer cabinet

[quaint ocean]

Or it’s corporate exploitation of people who don’t understand that you don’t have to spend $5 for two M5 screws

[sinful zephyr]

why not do kevin toolhead

[quaint ocean]

Same at Lowe’s

[sinful zephyr]

instead of stinger

[tawny swallow]

Dragon hf hotend

[strange cedar]

well, not a lot of people in the US are going out to the hardware store for metric screws

[tawny swallow]

And klicky

[strange cedar]

especially not to home improvement focused places like HD or lowe's

so the prices are higher

[sinful zephyr]

does dragon hf not fit?

[strange cedar]

kevin's toolhead is uhf length

[sinful zephyr]

oh yah

i ran into that issue

i needed to buy mze

[tawny swallow]

Yeah, I'm planning to use the dragon with an mze

[sinful zephyr]

so you will do kevins later on?

[tawny swallow]

I wasn't planning on doing so

[strange cedar]

nothing super special about it either way

[sinful zephyr]

it has offset and higher ducts

which is an improvement over the stinger

[strange cedar]

is this some sort of 5015 joke i'm too 4010pilled to understand

[sinful zephyr]

yes

and the reason why is because 5015s arent mirrored

[tawny swallow]

One of the 5015s is choked out on the stinger toolhead

[sinful zephyr]

^

[tawny swallow]

Toolhead with the spacer

[sinful zephyr]

the red is a noice touch

[tawny swallow]

Rails arrived

[tame orbit]

Where you order yours from?

[tawny swallow]

Aliexpress, these are rdbb rails

[unique skiff]

Just make sure you clean and relube them

[tawny swallow]

That was the first thing I did. Glad I got it out of the way first because it was messy

[unique skiff]

Nice

[tawny swallow]

Finally got m5 screws long enough for the complete z axis. The X axis is pretty much finished as well, I just need the actual motors as well as more filament because I'm out

[tawny swallow]

The rails are just on temporarily with 2 screws each (because I ran out of m3 T nuts)

[tawny swallow]

Taking a small break since I have finals coming up and christmas around the corner. All I have left to order is the bed and electronics.

[unique skiff]

Good luck

[tawny swallow]

Very slow progress

[tawny swallow]

ebox parts printed on a q1 pro because my ender 3 isn't big enough

[wanton aspen]

is there a cad file and bom for this?

[wanton aspen]

@tawny swallow okay i found the cad, how do i go about making one of these is it complete?

[tawny swallow]

It's not currently complete because humperdoe discontinued it, but I'm still working on the bom for it and adding things here and there

[wanton aspen]

so like, if i was gonna build one based on your f360 file

would it

work

[tawny swallow]

I'm sure it would, but the .cfg would have to be tweaked (from the original stinger)

Or you could make one from scratch

[wanton aspen]

oh thats fine

[wanton aspen]

how much did this whole printer cost?

[tawny swallow]

I haven't finished it yet so it's hard to say, but I estimate anywhere from 400 to 600 usd

[wanton aspen]

ohhh thats too much for me lol

[tawny swallow]

Yeah, if you're going for budget, I'd reccomend Kol's or Kevin's build

[wanton aspen]

Okay

[tawny swallow]

got all of the hotend stuffs

just a portion of it

i've been putting off redesigning the mount for the lhs breakout board but i'll get to it soon (maybe)

[tawny swallow]

waiting for the winter sale to buy the bed and the motors.

[quaint ocean]

I can’t tell if everything in this image is big or if that’s a little baby PSU

[tawny swallow]

it's definitely a little baby psu

[tawny swallow]

Still waiting for the mze, but the hotend is now here

[tawny swallow]

Small amount of wiring done

I could've finished if I didn't run out of fork connectors

I'll try to redesign the y axis motor mounts to be less bulky

[quaint ocean]

How’s that going to attach?

To the extrusion

[tawny swallow]

still figuring that part out

It might be something like this

[quaint ocean]

I would be concerned about the strength of the interface in that case

Also you’d have to create a channel through the entire part to screw those in

[tawny swallow]

They each will have to slide snugly into those screws from each side, then they'd be screwed together with the motors screws

I used the word screws too many times

[tawny swallow]

Not entirely sure how it will hold up over time, but we'll see

The bed has been recieved

[tawny swallow]

Current state of the ebox

I don't have a green or white wire that's flexible enough to bend like the ones shown, so I'll get those soon. I'm also out of fork connectors and terminals as well (which I'll also be getting soon)

[tawny swallow]

I'm gonna prototype the first version tomorrow hopefully

it should print in 3 pieces; the 2 red pieces need to be glued together

[cinder sinew]

Hi there. did u printing Ex body on FDM or SLM? 🤔

[strange cedar]

fdm

it's carbon fiber filled filament

[tawny swallow]

It's fdm. I used petg-cf for most of the parts.

[quaint ocean]

SLM is industrial stuff. Selective Laser Melting

Super expensive

[quaint ocean]

Are you at least making anything touching motors out of ASA?

[tawny swallow]

Yeah, that's the plan

[tawny swallow]

I've got the ebox all wired up and working

it only costed me a burnt out relay

totally didnt wire it backwards

[tawny swallow]

Not sure if it's the current version of cb1 software, but i cannot for the life of me get this pi to connect to wifi

I'll try an older version

[tawny swallow]

finally fixed it

no idea what was wrong

[tawny swallow]

I just need to order the breakout board and motors now pretty much

[tawny swallow]

The back wiring is only temporary for now since I blew my relay, but everything functions as intended

[unique skiff]

Very neat

Any reason for the one open driver slot?

[tawny swallow]

I'm planning on going off of the stinger's config

everything will be in the same place as the stinger except for the additional driver for the x axis

I could change it to make it neater though

[tawny swallow]

The 2 bottom pieces of the build plate have been glued together with epoxy

[tawny swallow]

currently making a version compatible with linear rails since it's an upgrade I plan on doing down the line.

[unique skiff]

Sleek

[tawny swallow]

gonna have to modify it to make it more printable

or not who knows

[tawny swallow]

ok that should be slightly better

[tame orbit]

How did bed mounting go?

[tawny swallow]

Gonna print out the mounts soon

I don't have them printed yet

[tawny swallow]

Ready to make the sock

[tawny swallow]

The bed heater is finally here

[tawny swallow]

The sock is a little bit messed up so I'm remaking it. It stuck to the mold a little

I might just re-print the mold though because I scratched it up a bit trying to get the residuals out.

[tawny swallow]

Came out pretty good this time, though I'm gonna make a few extra for later

[unique skiff]

Looks super clean

[quaint ocean]

I gotta get back in the saddle on my Ender

It’s been 2 months lol

[unique skiff]

I wanted to finish the vzbot in my summer vacation last year but here we are

[tawny swallow]

They always take longer than expected

[tawny swallow]

This one came out even better

[tawny swallow]

Magnets installed

[tawny swallow]

Ordered two because they were on clearance

[haughty basin]

Wait what

Where

I thought they were out of stock everywhere

[tawny swallow]

https://www.trianglelab.net/products/zstc-mk8-volcano-v6-zsd-mk8-volcano-v6-zs-mk8-volcano-v6-k1-nozzle?VariantsId=12008

[haughty basin]

Thanks

[tawny swallow]

Ordered 4 2004s

[tawny swallow]

And the breakout board

As well as this if you can even see it lol

[unique skiff]

Hope you told cna the wanted preload

[tawny swallow]

Yup

[tawny swallow]

still a load of things that I need to change but here's the progress for now

[tawny swallow]

fixed a few minor things, but I still have to figure out how to mount the breakout board

[tawny swallow]

Taking a break till June, though I'll still be working on the design

[unique skiff]

Good luck

[tawny swallow]

Ender-Stinger (Starting June)

A lot of stuff arrived

Accidentally got an extra 6mm belt instead of a 9mm belt though

The rails will be here soon, but the magnets still haven't shipped after 19 days

[haughty basin]

how much did you pay for the CF bed and heater?

[tawny swallow]

Gotta check

[haughty basin]

im thinking of getting one on my printer

im also probably gonna have to start working on the cad for AWD X bc if I upgrade my Y im gonna be X limited

[tawny swallow]

The heater was ~30 dollars and the cf bed assembly was $50

You'll have to be careful gluing the 2 bottom assemblies together or else it'll make a big mess

The heater was from provok3d and the assembly was from the fystec official store on aliexpress

Jb weld high heat works well, and it wipes off easy with alcohol pads.

The breakout board is in LA meaning it will probably be here in the next few days

[tawny swallow]

After about a month and a half of waiting, it's finally here

[tawny swallow]

Resuming sometime around june 8th

[tawny swallow]

A whole month late, but I'm gonna start once I get back from Idaho

Update: I'll start working on it eventually, I just don't have the motivation right now.

[faint scroll]

do you have some more pics of this mount?

[tawny swallow]

here's the step file for the right side

[tawny swallow]

The gantry and y-axis motor mounts are now complete, I just have to print them out in their final materials

[tawny swallow]

Ender-Stinger

Everything seems to fit together nicely in the mockup so far

[tawny swallow]

https://cdn.discordapp.com/attachments/1297690726301175838/1461939662158561365/20260116_202443.mp4?ex=696c60e8&is=696b0f68&hm=a5c7124975384b6498c03bff9d7e36e164ec21416951a60928be6b34dda2a852&

testing the y axis on one motor since i cannot for the life of me figure out how to get both working 🫠

[ebon meadow]

Are the rails oiled? Idk I think they are screaming for help

[tawny swallow]

they are oiled and are much quieter in real life

[tawny swallow]

looks like the reason awd y was not working was because of a dead y driver

same for the x as well

may have been caused by sitting in the garage for a year, but I'm not sure

[faint scroll]

thanks!

[tawny swallow]

No problem

[faint scroll]

oh wait that's not connected to the Z block

huh interesting

how did you connect the gantry to the Z?

[tawny swallow]

there is a single m4 screw connected to the gantry extrusion with a t nut

you can see it better from this angle

[faint scroll]

oh

isn't that rather weak?

as in not rigid enough?

[tawny swallow]

it was actually suprisingly rigid even when i test printed it in pla

I'm going to be using cf asa for the final part though so I have yet to find out

[faint scroll]

interesting

[tawny swallow]

the part where the tensioner is located is held on with heat inserts and m3 screws since they are 2 different parts

[faint scroll]

Yeah figured that out....that also doesn't seem rigid enough lol

I wonder how they'll hold up at higher accels

[tawny swallow]

Yeah I'm not sure yet, most of the z axis has been in the works for a while since I've been trying to improve the y-axis motor mounts

[faint scroll]

why not use 9mm belts for the Y?

[tawny swallow]

that is the plan, just made the mistake of ordering 2 6mm belts instead of a 9 and a 6

the 6mm belt on the Y-axis is a placeholder

[faint scroll]

ah

[tawny swallow]

Currently the x axis only moves in one direction for some reason and I'm waiting for 4 tmc2240s to arrive since 2 are fried

[tawny swallow]

Also ordered a new octopus pro because I'm almost positive two of the slots are fried as well 😭

[tawny swallow]

Finishing up the rest of the ASA-CF parts, smells absolutely wicked

[faint scroll]

you'll add some feet for the Y, right?

[tawny swallow]

Yeah, there's existing ones in the cad, but i want to see if I can redesign them

If not I'll just use the ones that lh made

[tawny swallow]

Old board was definitely fried

New one is much better

[tawny swallow]

I need to move the rails and endstop forward for the Y axis but it's alive 🥳

[tawny swallow]

Wires have been managed

(Before cable management)

[tawny swallow]

Still working on pressure advance, but I'm working on cleaning up the wiring a bit more before then

[quaint ocean]

I can see where you touched your print bed

[tawny swallow]

It was actually caused by petg sticking too well, causing the kapton tape to peel every time I took a print off the plate

Anyways, the wiring to the breakout board is now finished

(Inside the small boxes)
