Hi! :) This is a Stealthchanger with doom extrusions and custom paneling for integrated tophat. My priorities are to have a quiet and capable printer that looks good too.. the default tophats made the printer look large because of the visual separation between tophat and printer. so I tried to solve that issue.

For Toolhead will be made of tz v6 2.0+cht, protoxtruder 2.0, and ebb36. Originally planned Yavoth but now dragonburner for cat ears.

I'm coming from a Prusa MK4S+MMU but I wanted more things to tinker + upgrade on my printer :)

To start out, I'll be keeping the scope smaller by starting with 1 tool and no dock.

Unfortunately, 2 of my b length 2020s were bent in shipping so I've been working on gantry and tools first. magicphoenix is sending me replacement soon

I haven't seen other Vorons in real life, but the kit seems great quality to me, especially the heater (I paid for 800w upgrade) and the bed plate, which they make in-house

All of the fans are GDSTime dual ball :3 the electronics looks ok, weirdly all of the BTT boxes smell a bit like cigarette smoke but I don't expect it would be on the pcbs.

[formal pendant]

Welcome!

Enjoy the build! Stealthchanger sounds like a fun challenge.

[alpine galleon]

Looks like a nice kit!

[olive stag]

Thanks! It's been a journey going through draftshift, voron, mpx, yavoth, and various mod githubs for documentation lol

[olive stag]

Made good progress on the gantry today! I'm really liking the mpx screw organization box which is making it easy to find things.
I also assembled some parts of the toolhead. I made a longer spacer (6.5mm) to fit the tz w/ V6 nozzle in the Yavoth, but I forgot I'd need longer m2.5 screws to mount it :)

[alpine galleon]

I gotta say, the screw box is a nice touch. I have several spare 27 compartment plano boxes, but never bothered to transfer my screws from bags to box… Lots of fishing through the big ziplock for smaller ziplocks lol.

I printed that same nozzle torque wrench. Printed mine out of PLA, and I had to print several to get the right torque because of it lol. Love it though.

[olive stag]

I'm a big fan too, such clever use of 3d printing :)

I also greased all of the rails with EP1, and I'm happy with the MGN12 rail quality - it feels very smooth to me. it's a bit less preload than I expected but I'm not sure how much to expect. it just barely slides under its own weight, and stops at some points. but the ball bearing feeling is even.
As for the MGN9s, well some of them I feel a variance in the ball bearings more as I slide them, but it still slides well so I think smooth enough for Z axis. I cherry picked the 2 smoothest to become my Y's and those have even ball bearing feel and no slop at all.

[olive stag]

Well anyways, progress today :3

[pulsar jungle]

"Omorn SSR" xD. Nice Kit, I will definitly also get one!

[olive stag]

Yay, hope you enjoy yours!

[olive stag]

I'm still waiting on those replacement extrusions, it's been slow to ship it out :/ tracking says picked up on 4/24. pretty disappointing, and no movement recently

in the meantime, I bought some doom extrusions since I'm tired of waiting and it'll probably be held up by customs

[olive stag]

Ok I heard back, it was late to ship because of tarrifs, no cost to me though.

[olive stag]

So thick! These are the LDO doom extrusions for 2.4.
I'm going to build the frame finally

[olive stag]

squaring up the frame rn, I'm measuring about 0.5mm variance in some directions, is that ok?

[alpine galleon]

Yeah. You’re aiming for less than 1mm. 0.5<1.0, so you’re good. I forget what mine was…less than 1 for sure, but I was quickly running up against the limitations of a tape measure. Just know that you’re in the ballpark and you’re below the 1mm target. You’ll fight against your ability to take accurate measurements before you’re able to realize any gains. Call it good and move on👍

Oh, and I’m talking with diagonal measurements in mind.

[olive stag]

Oke thanks! I'll remeasure diagonals, cause I was doing each dimension separately

I made great progress today

Bed not on yet, just sitting

[west wind]

The doom frame looks so good

Dare i say bambu like

[olive stag]

Yea, I like them :)

[olive stag]

Today I finished all the belts, mounted the gantry, and put on the Cnc shuttle :)

Next up are the wiring, electronics, and toolhead

[olive stag]

I've been busy lately, so far I flashed my CB1 and did some power wiring :3 it was really cool seeing Mainsail on my browser

Mainsail gave me very home assistant vibes actually

[opaque prairie]

@olive stag did you see something like this pop up on your mainsail?

kinda weird it showed up on my browser and i dont know if its mainsail, or if its my browser but i dont know why it says anything aboujt home assistant >_>;;;

[olive stag]

oh weird o.o

I never saw anything like that

[opaque prairie]

im trippin out trying to figure out where it even came from lol

omfg

figured it out

old ass octoeverywhere install made it pop up ~_~

[olive stag]

ohh ok :3 glad its sorted

[opaque prairie]

the builds looking nice btw! @olive stag

[olive stag]

Thanks :)

[olive stag]

I flashed my M8p, CB1, and ebb36, and did a bit more wiring + mounting things. I feel like the hardest part is behind me now

[olive stag]

(I think) everything is wired except for the tool head :)

I had to grind down that back panel to make it fit inside the doom extrusions, it was maybe about 3mm too wide. But now looks great

[olive stag]

It moves !!!

[olive stag]

First print :3

no input shaper yet, I think I printed too cold.. I thought it was PLA but it has the petg shine

[olive stag]

I got to do some shaketune!!

to be honest, I forget if I put in the 2 of 4 screws on the one side of the X beam.. I remember the voron instructions said we'll put in 2 more later, but im away right now so I can't check

I wish the Y accel values were higher though :3

not sure if this is typical y accel on a stock-ish 350 2.4

[olive stag]

I'm building the doom enclosure slowly :)

I had to cut and tap the horizontal extrusions by hand, plus cut the panels to fit (originally from mpx panel kit), tons of manual labor lol

also it's dual paned :3

I have some cool ideas for the side panels, basically it'll be 1 solid dual-paned side panel that extends 250mm higher, and I'll print out some rounded 4040 extrusion facades to keep it looking consistent. Then, the top panel will be L shaped to finish the enclosure and attach to the 250mm raised back panel.

basically an integrated tophat for stealthchanger

[olive stag]

Update :D

Added:

1. Custom designed side panels and tophat based on doom side panel holders. I love the panoramic look
2. Hand cut dual pane everything (it was a lot...)
3. Hartk's Doom door 2020
4. MiniBFI (for sc)
5. Voron Double Cheap doubleshear + 1.5x stock belt tensions
6. Superpower S55 2804 ab motors
7. Bunch of config and TMC autotune work!

Soon I will put in nevermore and currently am printing stealthchanger parts. Switching to Dragonburner for the 3010 fans since I find 2510 cricket sound annoying

Doom Stealthchanger (v2.4 magicphoenix)

It prints super reliably now as well. I selected the Prusa XL in prusaslicer and changed the start and end gcode to jontek's, as well as saying it runs klipper and editing the build volume. It works perfectly, and the filament profiles seems close enough too. Lmao

[solemn bough]

Looks like a touch too much squish, but great layer stacking! You can tell it's too close if it gets that wavy look

[olive stag]

ah yea, I've been getting that on several prints, I think adjusting the tap offset should do it? or some other way

super happy with the layer stacking

[solemn bough]

Yep, try a big rectangle like 2-3 layers thick and adjust the offset on the fly

[olive stag]

Several bed adhesion issues recently with a freshly dish soaped biqu glacier. Im losing faith in this plate a bit

Petg at 90c on the heater and 80-83 top of bed thermistor

The bottom looked perfect, no extra squish

[olive stag]

I have a west3d ultra rugged pei plate on the way

And switched to all tmc2240 with 2x 5010 axial cooling on those. I love seeing the low temperatures

5x cat Dragonburner with angry docks coming soon^tm

https://www.printables.com/model/1461410-angrydock-dragonburner-for-stealthchanger

It looks so cute lol

[olive stag]

I'm getting side tracked because of these lol. I totally didn't mean to get a box turtle but I saw a good price on the garage sale chat here, it was an ldo kit which included the filament dryer and enclosure for $360. I think I will install this temporarily to tool 1 and then migrate it to the future 250mm trident once toolchanging is working well

I also am finally naming the printer Mango after my sister's old black cat

prusa orange color is so much better too. best orange

Mango

[olive stag]

I think it looks a lot better with the west3d rugged PEI plate, especially the silvery bare steel side (not pictured)

[merry halo]

That's a chonk printer

[olive stag]

I've been thinking it's a bit big lately too lol

I love the no panel clips though

But I think the tophat rly tips it into too big for me

[olive stag]

1 unit is ready, with a million 3 more well on the way
Happy with the clean wiring :3

[olive stag]

had to modify the bracket again to fit the stealthchanger Tap PCB for Dragonburner. also reinforced it while I was at it
https://www.printables.com/model/1543813-reinforced-ebb36-mount-with-protoxtruder-10-20-wit

also I put in the little overhanging holes trick I saw ;)

[merry halo]

Wot extruder is that

It looks like it has helical teefs

[olive stag]

Stealthprotoxtruder 2.0, it uses the HGX 2.0 gears

I like it a lot, extremely cheap and the extrusion consistency is good

Hard to tell how much of the z things are from lowish chamber temp so I judge by the upper layers (in pic 1)

[marble jackal]

What extruder is that?

[olive stag]

stealthprotoxtruder 2.0

[olive stag]

The units are assembled !!!!

they feel like dense nuggets. I love it

[marble jackal]

I have never seen it. What gearset is it based off of?

[olive stag]

It uses the HGX 2.0 gears set, which is somewhat like LGX but this is lighter and with oblique gears to grip the filament. No issue with the actual gear so far and I can't feel any backlash when I try to wiggle the outer pom gear. I really like how it's not so closed off physically and you can see it spinning. And large drive gears help a lot for extrusion consistency

[marble jackal]

So essentially the same idea as lgx lite except spring loaded gears instead of fixed?

[olive stag]

Yea, just the idler is spring loaded. I think the hgx 1.0 gears is a more similar clone of LGX and then 2.0 added some improvements

I think it's a sleeper budget extruder tbh. Gears only cost $10.57 each and then it's just M3 screws and printed parts

[barren mesa]

I have one also to mess around 😆

[olive stag]

Lmk how you like it! :)

https://docs.google.com/spreadsheets/d/1cawPPtowhvgX7oI8-SRqRrB30HbX-_QnhFgstov1qDI/edit?usp=sharing
I put together my costs so far, $1,740 for the printer and $2,084 if you include spares/extras that usually wouldn't be included in the "printer cost"

$530.80 for the 5 toolheads+umbilical and Stealthchanger items only

[olive stag]

Smol disaster

[olive stag]

I can't tell if it melted somehow or I didn't screw it down fully, or part was too thin

[merry halo]

I think it got hot and melted the plastic

[quick mango]

Is that a tz hot end? I had the same thing happen to me on an xol tool head

[olive stag]

It is, oh wow

I had the hotend fan at 30% which is the same as on Yavoth which didn't melt but that one was 2510 gdstime and this is 3010 berserker. So idk how it got so hot since the berserker is rated for a lot more cfm

[merry halo]

I think 30 is too low

I have a different 2510 (honeybadger) and I run it at 1.0

[olive stag]

Isnt it loud >.<

Sounds like crickets

[olive stag]

ok it must have melted because I tried slicing the default Dragonburner mount by chirpy and it had the same number of layers for the screw part

I was thinking maybe I forgot to thicken the other side when I made the tz cutout on that mount

[merry halo]

What are you doing to it to make it sound like crickets

[olive stag]

its just the high pitched noise

continuous cricket drone

[marble jackal]

is this supposed to be a budget stealthchanger as a cooler alternative to indx and the U1?

[olive stag]

yeah I wanted to keep costs down, originally I wanted to match the Prusa XL capabilities at low cost which is why I planned for 5 tools and 350mm. most of it was bought before the U1 and indx was announced but indx seems very nice and likely better performance.

I'm happy with it and the budget stuff is really capable! you have to go like 300mm/s+ to outrun the tz at 0.4 nozzle and 0.2mm layers

I'm keeping the 5th tool as a spare and then putting in my spare nextruder parts for a new 5th but that's likely for after the 250 trident is up and running

[olive stag]

We're so back

[olive stag]

I installed The Filter main + right side. I didn't have the quick disconnect so just put them on wagos lol. a lot cheaper too and there's wire slack so I can pull out

And also put in the sexball probe for stealthchanger stuffs :3 I hope to modify The Filter left side so I can cram that in around the probe while still looking symmetrical

[marble jackal]

It looks awesome

I just ordered 3 hgx gear sets

2 for boombox and one for my ultra budget ender 5

[olive stag]

Oh nice, I didn't realize boombox used those !

[olive stag]

I put in these SVS SoundPath subwoofer feet I had laying around, I super highly recommend it! It cut down on the vibration and non-continuous noises by what feels like over half

All I did was slice the default feet plate stl with a negative volume in the top lip section so it was fully flat. And then used all the same screws to hold on the feet

[marble jackal]

Are they rubbery enough to stick to a table for a v0?

[olive stag]

I think so. It's for sure much grippier than the stock V2 feet. I had to print some coasters so I can still slide my printer around lol
It's a soft rubber texture feels like silicone

[olive stag]

I put in bottom panel insulation and a 36v power supply!

[olive stag]

I just got my first toolchange!!!!!!

t0 -> t1 -> t2 -> t3 worked like a charm

[granite arrow]

awesome!

im looking forward to seeing your machine print

(and then maybe il gatter the motivation to continue work on Chubechanger )

[olive stag]

;)

I hit kind of a strange snag, the berserker fans are a little thicker and get overcontrained by the dragonburner cowl. so T0's hotend fan doesn't spin anymore lol

[granite arrow]

idk what Chirpy recommends for fans for dragonburner but id just stick with his recommendation 😅

[olive stag]

Im not sure either I thought the berserker was ok
but for now I remapped t1-3 onto t0-2 and gonna fix t0 later

[granite arrow]

his github recommends gdstimes and maybe the berserker beeing thicker causes issues 😅

[olive stag]

yea must be >.<

maybe I just order one and swap it

probably less work than remapping the config, I forgot it does the probe_calibrate value off the old t0's number too

[granite arrow]

yea and gstimes are cheap enough

[olive stag]

hehehe but what about sandpaper

;)

[olive stag]

I took the fan out and started sanding, but noticed it gets caught with even the smallest squeezing force

so I measured the fan and it was 29mmx30.4mm

it only got caught when I squeezed it along the 29mm dimension so I rotated the fan 90 degree and put it in, all fixed!

I didnt want to wait 2 days for new fans so I am pleased ^^

definitely getting those gdstime next time

[olive stag]

fingers crossed for first multicolor print :D

[olive stag]

omg it works

[olive stag]

First two prints (Micky 1st and candy came 2nd)

Also rate my filament management system

[granite arrow]

awesome!

[merry halo]

Speedy

https://tenor.com/view/voron-magic-smoke-electronic-desaster-gif-26145841

[olive stag]

Lol apparently I have headroom still, I'm on 36v and 180mm/s z speed

But I don't want to risk deracking lol. It moves so fast I don't think I can hit estop without damage first

[olive stag]

I really need to fix the issue of my umbilicals hitting each other and sometimes tangling

Just need to extend the spring steel to the toolhead and it should work but I only have 1 roll left which is not enough for 4 new runs.... And this supplier doesn't ship to the US anymore. Sooo I'm going to design some custom thing for my toolboard bracket to the and redo the closest tpu holder to attach there

As well as rear mounted filament sensor and some filament management system

[merry halo]

Order umbilicals from whiskers

He has fancy titanium wire too lol

[steep oriole]

I think he’s swapping back to spring steel for that nice new thin wrapping method iirc though

It may take a lil bit but dudes putting good effort into making some quality harnesses

[olive stag]

Scope creep detected!

My umbilical wire rn is just some 4 conductor cable from Amazon

[olive stag]

Stealthchanger is very reparable, I'm happy about that. My config was messed up and crashed into the dock... It broke a pin but the swap is super easy

I wish I took a pic of the twisted gantry. It was wild, 30 degree angle at least

But the gantry is just fine somehow

[olive stag]

And the one time my extruder broke I was able to slide it out and put in a new one with all of the electronics and motor still attached :3

[marble jackal]

What extruder motor are you using? It looks super fat

[olive stag]

https://a.aliexpress.com/_mLYGMOz
It's a no name aliexpress motor that I got bundled with hgx 2.0 gears. Works alright but the seller wouldn't tell me the motor characteristics for TMC autotune

$6.88 per motor

[olive stag]

Btw, if anyone is considering upgrading from sexball probe to the axisoscope for sc nozzle offset calibration, I say don't bother... Sexball is super accurate and automatic, the only downside is it takes a bit more time to run through the whole routine which isn't a problem if you aren't switching hardware often

[marble jackal]

Thanks for the info

I would rather just have a set and forget option

[olive stag]

I am printing useful things now!! Player piece containers for Twilight imperium 4
For printer updates, I added the nozzle wiper (only for at start of print), and a new custom ebb board mount that mounts the spring steel directly so my umbilicals behave.
I still don't have nozzle blocker or wiper on my docks but tbh, it's printing great without them? Soo I think I might just run some more prints first
These are all 2 color PETG prints too, worst case scenario for oozing or stringing.

These are 150 toolchanges per print, 3rd print with no fails

I'm so happy with the sexball and nozzle wiper placement, they juust fit within my 0 to -9 Y axis so I get 0 xy loss and the full The Filter setup with this

oh I customized the left side of The Filter to fit around the sexball and got that usermod pushed to main in the stealthchanger github! :) (visible in pics 2 and 3)

[olive stag]

I had it running nonstop the past couple days and the toolchange wheeeee is driving me nuts lol. it was cool for the first couple hundred

I'm going to look into the moving dock mod

[olive stag]

well its ok at 42mm/s. but slow

[olive stag]

Added lights and 2 more chamber themistors :3

My front z drive is creaky... no clue

[olive stag]

Its crazy how fast toolchange prints are compared to the mmu3! Only 5 hours for that one

And my z speed is way low for noise too

[marble jackal]

I have a cheap upgrade for your machine. You already have a 4040 frame

[olive stag]

lmao for the low price of $300+

[marble jackal]

It should have a perfect center of mass though

And enough space to fit 7 tools with a lot of extra space

It is 10mm off of fitting 7 in a 350 awd machine

[olive stag]

https://tenor.com/view/monkey-working-computer-fire-burning-work-pressure-gif-797541937587978407

just a little scope creep

[marble jackal]

I am personally using conducts but i will be doing a version with goliath, chube compact and dragon ace volcano

Appri, jakob and mikeymike are helping with the project

[olive stag]

I might put a chube compact in my t0 but other than that I want to work on my trident more over time

[marble jackal]

I could do a tz v6 one but I don’t think the slm order would be worth

Everyone i have shown it to wants a tz v6 version

They don’t understand that the slm order for 7 toolheads and the shuttle would be way too much money to be worth it

[granite arrow]

yea cause its cheap af lol

and ngl for the price its pretty decent

[granite arrow]

slm is gonna be expensive but expensive slm + cheap hotend is a lot more afforable then expensive slm + expensive hotend 😅

[olive stag]

Most prints are 1 maybe 2 tool so I can see a mix of hotends being a good setup

lile you could set a different filament profile with the volume limited and those are usually accent colors anyway

[marble jackal]

I can make non com accurate printed tz v6 tools @olive stag @granite arrow

As you can see the part will print

[granite arrow]

thats pretty neat!

[marble jackal]

And i printed that one with way overkill speeds so it looks like crap

[granite arrow]

also dont forget the top plate would need to be obtainable as well .. but should be just as easy to slm print it right?

[marble jackal]

You mean that extruder plate? That is for lgx lite only at the moment but you can buy the plates from luke for 10$

[granite arrow]

ah ok .. yea would be neat if you would slm print it as well. Only having a single source for a required part would limit availability. Ordering from the us is .. expensive at the moment

[marble jackal]

It can always be slm printed

It is just a plate

I wouldn’t use lgx lite though

It is ehhh for how heavy it is and how much it costs

I will probably be doing a sherpa one for MikeyMike as well as a sherpa/tricorn one

Those should all be relatively easy

[granite arrow]

yea can never go wrong with the sherpa 😅

[marble jackal]

Yeah i am really not a sherpa fan but I can’t deny the performance and weight

I can always do wwg2 but that thing is heavy like an lgx lite.

[olive stag]

Is the com balance so important? Isn't it adding more weight on

[granite arrow]

both is important but better com results in the toolhead wobbling left/rigth and front/back when doing quick direction changes

its a lot easier to get rid of ghosting when com is good and your going fast

[marble jackal]

Yeah COM and cooling are the 2 most important things in in a toolhead

Weight still matters but it isn't as important when it comes to pushing higher speeds with a modern printer with higher tension belts and sometimes awd. The motion system is designed well enough to handle a heavy toolhead like takeoff

A lighter toolhead is more important on less beefy machines like Xair's microwave build with 6mm belts and a motion system that doesn't have much torque

Even wayne was able to hit 34k y on a 300 2wd partially due to the super light monolith toolhead

[olive stag]

I was thinking, for speed id do some easier upgrades first like 2wd printed 9mm mono and the carbonara beam

redoing all my tools is a ton of work

[olive stag]

durability update: small issue with the magnets coming loose from the docks and the dragonburner, I think I need to dunk it in superglue. otherwise so far so good

[granite arrow]

yep i had to glue some in as well

[olive stag]

Input shaper in current state @near anchor@valid light :3

[solemn bough]

looks nearly identical to my V2 when it was on stock gantry

[olive stag]

yay

[marble jackal]

Yeah that is really good
