M1.1/EVA 3/Dual-Z/Custom enclosure

[tiny bramble]

Yes indeed

Lower bay for SSRs

[cedar depot]

and a mosfit ?

[tiny bramble]

yep

[cedar depot]

Looks liek I will need more files

100 Hr print

lol

[tiny bramble]

Space will get tight in there with that, though. You'll want to skip the side panel with keystone jacks; the cable extensions will take up too much room. Use the PI4B tray instead.

Dangit, ignore me.

[cedar depot]

huh

[tiny bramble]

I'm tired and recommended an old tray.

The universal CPU tray (https://github.com/jon-harper/OmniBox/blob/0.9.9-frozen/Trays/CPU/Raspberry Pi Universal/CPU Tray - RPi with Fan.stl) is the one you want. But the side panel with keystone jacks does not work well with that tray at all; you'll have better luck with the front panel with keystone.

Sorry, I'm really tired and not explaining stuff well.

[cedar depot]

its ok need some sleep then

[tiny bramble]

Yeah, definitely. Don't start printing the front and rear case body yet. I'll explain tomorrow.

[cedar depot]

cool

Will wait for sure

[tiny bramble]

Thanks dude

[cedar depot]

Anytime

rather only print print ounce

if I can

[tiny bramble]

Agreed. Filament may not be expensive, but it's not cheap, either.

[cedar depot]

that and time

est to print

[short cove]

I did the same and it has seemed to work well

[tiny bramble]

New power supply should be here today.

Still have not determined why the Pi in Big Bird will not talk to the Octopus.

[tiny bramble]

Can't wait to get this power supply.

[potent stone]

have you tried via uart instead of usb?

[tiny bramble]

It's in CAN bridge mode. 😬

If I reflash...

[potent stone]

ahh, what does lsusb/dmesg tells you?

[tiny bramble]

it ain't there. 😦

It says: 😭

[potent stone]

have you set the usb pins correctly, right?

[tiny bramble]

Nothing changed. It just stopped talking. I may have caused it from updating my distro. I applied the patch, thanks Maze, but it won't show up at all.

The ONLY way to get it to connect is when I power it on. As soon as I try to print, though, it loses connection and won't come back.

[potent stone]

ahh, so it’s an host issue

which distro?

[tiny bramble]

Raspbian or Raspberry Pi OS or whatever the name is now.

Installed through a MainsailOS image

[potent stone]

I think in this case is best to backup and roll back 😅

[tiny bramble]

I doooooo have a spare image. I can backup my config and swap the SDs.

[potent stone]

I have a git repo in the config folder, I commit an push (when I remember) so even catastrophic sd meltdown results just with a swap of sd install os and pull from github

[tiny bramble]

I do the same thing!

I just never update it...

So, new mission, backup and swap.

Maybe I can get TWO mercs running today.

[potent stone]

despite my compulsive updating OS disease, I keep the OS. to a minimum up to date status, only bleeding edge on klipper and related stuff. this machine do kot need yo have the latest PnP tech or any fancy things, just wifi and usb, basically 😅

[feral prawn]

I do my backups through automatic zfs snapshot

for a PI might be overkill running ZFS

but I got mirrored disks as well

[tiny bramble]

Yeah I'm not so fancy, heh

Although I've always wanted to play with ZFS

[potent stone]

it might dent the already limited i/o performance od the sd… right?

[feral prawn]

on the SD not much I would say but RAM...

that thing is hungry

might require some tuning

I don't run pis anymore, they're hard to find and not that good

(for the current prices you might find them)

[potent stone]

all the (cheap) arm devices are all a bit disappointing

[feral prawn]

might eventually spend some money on something less energy hungry with better performance to replace my very old i5

[potent stone]

if only that market would go au pair with apple silicon and qualcomm chips

[tiny bramble]

Not having Cortex M7 or equivalent is the problem. The cheap clones don't have advanced features. Sure, it's 1.5GHz or whatever, but it may not have out-of-order execution or some other stuff because it's a Cortex M4-equivalent.

[feral prawn]

for the same money or almost the same you can get amd64 arch stuff with nearly identical energy consumption

[tiny bramble]

Does AMD sell SoC CPUs?

Also: I AM STUPID. I didn't CAD the LRS-450. The mounting holes ARE different.

[feral prawn]

think they do so does intel

there are some decently priced NUCs

[tiny bramble]

I'm so out of date on hardware

[cedar depot]

I just got a amd 5950 with asus 3090 strix card

4090 out of range

[tiny bramble]

I can't afford to upgrade my PC and still fuel my printers. 👿

[cedar depot]

Yea gets expensive

[tiny bramble]

Printing a new PSU mount for the LRS-450

[feral prawn]

not easy, I'm going into savings mode exception being the remaining things that might be needed to finish my current goals for the printer

[potent stone]

yeah, me too, I’ve almost finished… I only need to make a corexy laser cutting machine to cut proper panels for the printer, and I think that’s it

[tiny bramble]

Does it really need to be CoreXY if you're just cutting panels?

Laser cutting is a slow process, right? So zipping around isn't important?

[potent stone]

looks cool, also it needs to be another money pit, right?

[tiny bramble]

https://hackaday.io/project/160914-the-spice-must-flow-sand-table

[potent stone]

I’m actually scared about the laser, do I’ll probably never ho around and make one… maybe a small router though

[tiny bramble]

I want a drill press like whaaaat

[potent stone]

I had a weird idea the other day, here they consistently trash greenhouses (I also disposed of mine years ago 😅) which have meters long aluminium extrusions… they are weird shaped.. but they are free

building something big that draws or cut would be nice

[tiny bramble]

Ever heard of FarmBot? I just discovered it.

https://farm.bot/

[feral prawn]

might be selling one, want to pay shipping from EU to US?

[tiny bramble]

The weight alone to ship in the U.S. would be insane. Can't imagine international, lol.

[feral prawn]

about laser, don't buy chinese, get non chinese protective gear (glasses)

[feral prawn]

and yet I ordered mine online, on Amazon!

[tiny bramble]

What should I expect to pay for one?

[feral prawn]

paid 7.5euro for shipping

[feral prawn]

price wise for the press?

[tiny bramble]

yep

I know zero about this stuff

[feral prawn]

153euro was mine, ryobi 390W (dont know the exact reference)

[tiny bramble]

Okay, that's not 400 and reasonable

[feral prawn]

https://www.amazon.es/-/pt/gp/aw/d/B073HF6D42/ref=ya_aw_od_pi?ie=UTF8&psc=1 right now sells for 250

fuck me that thing went up

https://www.amazon.com/5-Speed-Benchtop-Drill-Press-Alignment/dp/B0BFQYZPQK/ref=mp_s_a_1_2?crid=2K9FGBQPD5GQE&keywords=drill+press+ryobi&qid=1685648160&sprefix=drill+press+ryobi%2Caps%2C244&sr=8-2 very similar

if it's not for professional use looks good

[tiny bramble]

Sweet, thanks!

Yeah, just want to be able to drill and tap my own extrusions.

[feral prawn]

ever heard of skill saw? yep the brand ended up being used for the tool

[feral prawn]

should be enough

[potent stone]

yeah, but if I do start a new project like that I have to hide it somewhere my wife would never see

[tiny bramble]

Need more than protective glasses when she gouges your eyes out.

[potent stone]

the christmas decorations promise can’t be used anymore, I fear

[tiny bramble]

B-b-but they'll be laser engraved!

[potent stone]

i mean yeah !!

[feral prawn]

I actually printed some

with our names

[tiny bramble]

Next year: chocolate deccorations!

Then titanium...

[feral prawn]

need to print one for the newest cat

[potent stone]

is the chocolate printer working?

[tiny bramble]

Awww, what cat # is this

[feral prawn]

second cat

[tiny bramble]

Yep. Cocoa Press launched/started shipping about two months ago.

[potent stone]

yeah, seen it 😍

[feral prawn]

name actually makes sense for him Loki, he is indeed mischievous

[tiny bramble]

Very good cat name

[feral prawn]

black long hair

the cat

[tiny bramble]

English is so stupidly weird. "black long hair" is technically correct but sounds wrong to native speakers.

There's some not-quite-official ordering for adjectives, apparently?

And it cracks me up when I run across it.

[feral prawn]

I was going for black only

but then remembered it's also long

[tiny bramble]

Ah, maintenance issues?

[feral prawn]

wording wise

I already had another with long hair

[tiny bramble]

And, the thing is...you're technically correct.

[feral prawn]

non native speaker issues

[tiny bramble]

Yep. But ask me to tell you the correct order? I can't put this nonsense into words.

[internal screaming]

[feral prawn]

dafuq

[tiny bramble]

Right?

I have a lovely, short, cheap, old, oblong, green French whittling knife. <-- Why is this order important? DID LOKI DO THIS?!?

Anyway, build log related:

This power supply is tight. Like, may have to do some funny business to get it to fit and not be an issue with the toggle switch.

[feral prawn]

fucking weird

[tiny bramble]

Here's the issue with the switch.

I can move it over, but it won't work with socket head screws again.

Mrm.

What about a base without a power switch? Move it to the front panel or rear panel.

Eh, easier: steal the front base from the old 0.9.9 case and use the rocker switch. That fits.

This is quite frustrating. I'm going to have to rip apart the case to get to those base mounting screws.

The front two are easy, but the pair behind that are harder to reach.

[cedar depot]

@tiny bramble should I wait on the 9.1.0

[feral prawn]

now there's something I need to buy if I rebuild the original ender

[tiny bramble]

This is unrelated. It's a different power supply I'm making a new mount for. 🙂

[tiny bramble]

The switch?

[feral prawn]

yep

[short cove]

Would only be better with some nice red sand

[tiny bramble]

And a stillsuit.

[tiny bramble]

Maaaan I got this LRS-450 all setup and ready to go, but the toggle switch touches the PSU. 😠

I guess rocker switches only for large PSUs. 😦

[cedar depot]

Oh

[tiny bramble]

This is the same PSU as before. Do you have a Pro or Plus?

[cedar depot]

Already downloaded the files going to start the project this weekend

I have the plus

[tiny bramble]

Ah fsck. I thought you had a Pro. You will definitely need the rocker switch then. 😕

[cedar depot]

I sold the pro 2 days ago

[tiny bramble]

I guess the question is, you're using an RSP-500 power supply for the plus, right?

[cedar depot]

Yea

Meanwell 500

[tiny bramble]

Okay, yeah, you'll need to go rocker switch. That PSU is HUGE.

[cedar depot]

Yep

[tiny bramble]

I am so tired. 😦 I really need a good night's sleep.

[cedar depot]

Well it is almost weekend depending on where you are located

[tiny bramble]

I'm in DFW, so yep. Getting there. Hopefully we'll get some rain.

[cedar depot]

[cedar depot]

Cool

@tiny bramble I'm In Ohio

[cedar depot]

@tiny bramble eastern

[tiny bramble]

Thanks. I never know where the line is for eastern time.

[cedar depot]

Yea

[tiny bramble]

Nice

[cedar depot]

Yea I use m.2 ssd for printers

Sdcards fail too much

[tiny bramble]

Update: Swapped SD card. Still does not detect the MCU.

[feral prawn]

dmesg says anything when you connect disconnect

[tiny bramble]

Good question. I was going to just swap the Pi.

[tiny bramble]

It's showing up ATM in dmesg and lsusb

Can't connect. No device in /dev

there's serial0 -> ttyAMA0 actually

OH, duh

gotta configure this device for CAN

rebooting pi aftering configuring CAN

CAN works on the pi

Ah. It's saying the CAN network is down. Hrm.

No effect.

[loud swearing]

[cedar depot]

@tiny bramble bad sdcard ?

[tiny bramble]

Two different SD cards, two different RPis. 😕

[cedar depot]

Ahhh

Reflash firmware on octopus?

[tiny bramble]

Not likely, since it was in operation and stopped, but I can try.

[cedar depot]

Work ? Y or N

[tiny bramble]

Haven't tried yet. Probably will do it this weekend.

Having a frustrating day, I guess.

[cedar depot]

Oh ok

Going to start printing omni box tonight

Hopefully it turns out good

[tiny bramble]

Hope so, too. Drop by the Discord if you want to ask questions during your build.

[cedar depot]

How many hours did it take to print estimate

Oh I'm always on discord

[tiny bramble]

OmniBox Discord 🙂

[cedar depot]

Ok that discord group

[tiny bramble]

Can't really say for sure, since your printers are all CoreXY. Travel speed and accel make a HUGE different in time.

[cedar depot]

Well true

[tiny bramble]

More than most projects, because of the distance between the walls. It's like 160mm travel each way for the main body walls.

Watching the rear main body go up is kinda fun that way

[cedar depot]

How many rolls of filament

If I need to get some tonight I can

[tiny bramble]

About 1.25 max

[cedar depot]

Ok that's nothing

[tiny bramble]

Mmhmm. Not too bad at all.

[cedar depot]

Nope

I'm printing a F1 car on the zero g right now

[tiny bramble]

oh sick

[cedar depot]

Redbull car

[tiny bramble]

Oh wow. Those are great prints.

[cedar depot]

Match the mcclaren lego I built

Legos

[tiny bramble]

Some moron completely wrapped a McLaren up the road from me.

[cedar depot]

Nice

1.5 hrs left of work then print time

Lol

[potent stone]

@tiny bramble does the Rpi reads from a usb stick using the same usb port? it could also be the usb of the mcu or the firmware. but that would be odd since it worked before 🤔. I would 1) try another usb device on the same port (camera/usb stick whatever) 2a) -the usb worked- swap to the usb only firmware of the octopus (no can bridge) and see if you see the mcu 2b) try another rpi/usb port and repeat

[tiny bramble]

I tried a second RPi and had the same issue, but i'll try USB sticks.

[potent stone]

it can be the cable, weird that dmesg doesn’t say anything at all

[tiny bramble]

Dmesg does sometimes. The first time you asked me, it couldn't see the device. The next time I tried it, the device is there.

[tiny bramble]

It shows up for a short bit after power on and then disappears, basically.

Also tried 3 USB cables

[potent stone]

Can you get the dmesg message right after the device disappears?

[tiny bramble]

#1063165805774245999 message <--yep

[potent stone]

Hoo sorry I’ve missed that

[tiny bramble]

You're good; I figured. 😉

[potent stone]

It’s a rpi4 64 bit kernel?

[tiny bramble]

Uhhhh

[tiny bramble]

Whatever MainsailOS comes with, basically

[potent stone]

Weird, you might have found he same stuff I did on google… have you tried to change your boot cmdline? Adding this usbcore.old_scheme_first=1

[tiny bramble]

What does this do and how do I change it?

[cedar depot]

@tiny bramble you get it working ?

[tiny bramble]

lol, not yet

[potent stone]

You need to edit the file in /boot/cmdline.txt

It will try to apply an older enumeration schema for high speed usbs

It’s something windows does since Windows 8

[tiny bramble]

nice. I'll try that

[potent stone]

Also you might have to check that you are running in 64bin only

[cedar depot]

pronterface connect the printer

via usb

[potent stone]

In /boot/config.txt:
arm_64bit=1

Warning, I am not using a rpi nor mainsailOS, so I just reading things that I find. i use armbian (which also works on rpi if you ever want to try)

[tiny bramble]

Fell asleep early. Sorry y'all.

[tiny bramble]

About to put together Oscar with the new PSU tray. I reassembled Big Bird as it was and will try tmrw.

[tiny bramble]

Oscar is reassembled and preheating for a print. Wooot!

Layer two, no shift. [dances]

[short cove]

Winning!! It’s always nerve racking after a rebuild.

[tiny bramble]

Particularly when it involves swapping PSU and stuff. Too many uncomfortable accident opportunities there.

[short cove]

Trying redoing the frame completely!! That was the worst lol

[tiny bramble]

Ack! I did a partial redo on my frames just to get the tapped brackets out and that was bad enough, lol.

[potent stone]

nice!! so indeed it was a power issue! it’s crazy that those were the symptoms, I would expect shutdowns or the rpi throwing all sort of other errors 😅

[tiny bramble]

Power issues are super subtle and hard to diagnose because they make everything else act weird. Thankfully they don't happen often!

Meh. A few uneven layers. Something else is up, but nothing like before.

But, I still had accel at 8k. Dropping to 3k and trying again.

[tiny bramble]

Still shifting, but much less so since the PSU swap.

[tiny bramble]

That belt is riding up.

Definitely too high in #4.

And that's why. Second pic. Must've raised it when I added locktite.

[internal screaming]

[tiny bramble]

Huh. I bet that's going to be the weird 100Hz spike on the bottom belt's resonance tests.

Negative. Still there.

[tiny bramble]

Input is shaped, heating up.

Much better

[tiny bramble]

First two layers look normal.

It's printing okay. Sigh.

[cedar depot]

good to hear

Im resin printing right now

[tiny bramble]

Resin printing is awesome but I don't want to deal with the fumes

[cedar depot]

Yea I have carbon filters

clean up is what I hate

[feral prawn]

same, fumes washing curing etc

[cedar depot]

yea

Yea I prefer the fdm

[tiny bramble]

Wow, two printers behaving very well today. Got a lovely single-piece stick diffuser off of my stock Ender 5 build plate. 275mm turned at 45 degree angle fit just barely.

[tiny bramble]

Oscar: E-steps calibrated. On to pressure advance.

[feral prawn]

I wish

[tiny bramble]

Extruder still not working?

[feral prawn]

sometimes

[cedar depot]

@tiny bramble looking good so far omnibox

[tiny bramble]

Still finding problems.

When the toolhead is as far forward as possible and towards the left of the build plate, this happens. Belt rides up the toothed pulley.

[tiny bramble]

Better picture. You can see the belt's reached the top of the tensioner's idler and is now twisted at the toothed idler.

[tiny bramble]

Big Bird: So the first SKR is causing its own issues. I have another that I'll swap in instead.

I did try a USB stick and the Pi seems to detect it fine.

It looks increasingly like I will need a new MCU, unless I get the other SKR working and use a buck converter for the case fans.

And lights.

[tiny bramble]

So neither SKR worked. I forgot one has the will-short-your-usb issue and the other was toast.

Wound up ordering another Octopus, FML.

[potent stone]

do you have any other boards?

[tiny bramble]

lol, I did. I sold it. 🤣

[potent stone]

I was going to suggest the skr mini or pico but I just remembered that they need the transceiver 🤦‍♂️

[tiny bramble]

Unfortunately I have a lot of 12V stuff on this printer and need the adjustable voltage levels that the Octopus has. Realized that when I was trying to put the SKR 2 to use.

[cedar depot]

@tiny bramble https://www.printables.com/model/455653-bambu-filament-winder-spooler-remixed/files working o nthis at the moment ....3 rolls with tangles

There is one of the roll the tangle I cut out

[feral prawn]

damn

[tiny bramble]

Big Bird: new Octopus is working

[cedar depot]

nice

[tiny bramble]

Opened up Oscar this morning.

Swapped out the spacers for the left toothed idler, hoping that would help. No.

Replaced the front face with a new one that's like 0.2mm adjusted. No did not help.

Reran belts. Still rides up on the toothed idler. Can't use the left half of the build plate, basically.

Next I guess I'll take the steppers off and try to re-adjust the pulley position?

Just don't know what else to do.

Also replaced the spacers for the toothed idler, just in case.

[cedar depot]

Oh man

@tiny bramble are you able to move the steppers freely until the belt moves up ..maybe a bad bearing ?

[tiny bramble]

Yes, steppers move freely until the belt rides up on the toothed idler pulley too far.

[cedar depot]

Tension correct ?

[tiny bramble]

Yep

Or was, at least. Its been loosened since I've worked on it today

[cedar depot]

I used a gutiar tuner for mine

both steppers same run currrent etc.. im reading

[tiny bramble]

I'm going to look into it being a bad bearing more, I think

I haven't pursued that yet at all

[cedar depot]

@tiny bramble X and Y steps/mm different in the M92 command? Thet would normally be identical for a CoreXY printer.

[tiny bramble]

Steps are the same. The only issue is the belt rides up on the toothed idler when it crosses the halfway point on the build plate (on the X axis).

[cedar depot]

ok I was looking at the wrong axis

[tiny bramble]

No worries

But it's probably the toothed idler or the tensioner idler, right? otherwise I'd see it on Y axis moves, too. I think.

[cedar depot]

same size idler gears ?

[tiny bramble]

Yep, both the 8.5mm idlers

[cedar depot]

ok same as mine

[tiny bramble]

I don't have a spare toothed idler, so I'll swap out the tensioner bearings next.

[cedar depot]

yea

I have spares just in case

[tiny bramble]

Didn't help, but the toothed idler does look a little funky.

[cedar depot]

pic

how about the pin the bearing sits on

[tiny bramble]

Left (normal) v. right (looks a bit canted on the bottom lip)

But right may also look funny because of how the belt bends

Also can't tell if it's riding up the tensioner because of the toothed idler or vice versa.

[cedar depot]

left pic the gear looks higher on the bottom unless thats how its supposed to be

I dont have the 1.1.5 on yet

[tiny bramble]

I think that's a combo of it being two pictures at slightly different angles and the toothed idler being thinner than the bearing stacks.

[cedar depot]

ok

[tiny bramble]

The bearing stacks are bigger now, too

[cedar depot]

let me look at mine

looks like the gear is closer to the printed part

[tiny bramble]

It does, but I think you've got a small gap in there above the idler

[cedar depot]

yea i have a spacer

[tiny bramble]

gotcha. let me look at my other 1.1.5

[cedar depot]

also looks like i need to replace the part has a crack in it

[tiny bramble]

i see it!

[cedar depot]

just noticed that

those are the 1.1.4 anyway

now that I have the voron up and running Ill print the 1.1.5's

printing the nevermore v 6 right now

[tiny bramble]

nice

[cedar depot]

moving v5 to the zero g

parts arriving in the next 3 hrs or so

TODO:
This changed drastically since the last time.

1. Oscar: Install new toothed idlers and cross fingers
2. Big Bird: figure out CAN issues:
   • slow down to 250k from 500k
   • reterminate Molex MF3 if that fails
3. Big Bird: test belt alignment resolution.
4. Big Bird: figure out best way to add more wattage to the system
5. Hopefully get this far.

[potent stone]

I had to replace a toothed idlers, it was visibly wobbly. I git a pair locally to replace it from 3do, and they were slightly different… but they still work okay. tbh also my belt tends to go on the upper part of the idlers

I think I got a “mellow style” toothed idlers

they have basically no bazel

[tiny bramble]

Hrm. I'm getting more of the kind I got last time, but I also got 4mm x 30mm dowels. Cuz I happen to have 20t toothed idlers with a 4mm bore. Less breakable bearings in that.

Now that the STEP file is out, can modify the X joint for the 4mm dowel if I want.

[potent stone]

it should a walk in the park for you, right?

I would mess it up 😅

[tiny bramble]

lol, let's hope it doesn't come to that. I'm gonna try swapping idlers first.

[potent stone]

you are lucky you are in the us, if I had the dowels/idlers on hand and your issue I would have gone through the step files already. shipping cost or delivery times makes you want to use what you have on hand

[tiny bramble]

Yeah. We're pretty spoiled.

[potent stone]

on hand at hand?… hope it’s the same 😅

[tiny bramble]

On hand = have, at hand = nearby or soon

[potent stone]

ohhhh, reeally? thanks!

[tiny bramble]

"Close at hand" is the most common for "nearby", but "[something] is at hand" is a dramatic way of saying it's coming soon or imminent.

This language is so LOLtastic.

[cedar depot]

@tiny bramble you get it resolved

[tiny bramble]

Not yet, but definitely ahead of two days ago.

[tiny bramble]

Big Bird: Slowed CAN to 250000. No change.

Now what?

I guess a continuity test?

[cedar depot]

Im running Utoc to canbus

[feral prawn]

@tiny bramble what's the CAN issue?

[tiny bramble]

No talky talky. Found a loose pin on the CAN connector, but it's something else. Might be a wire break.

Tried lowering the CAN speed (was too high anyway)

[feral prawn]

check wire resistance?

[tiny bramble]

About to do some continuity testing, I think. Could be this janky cable I made for the last leg of the CAN.

The Octopus should not use RJ-12 for their CAN jack. Just...no.

[feral prawn]

RJ12 is fine, if you have tools for it

[tiny bramble]

Thankfully I do. But it's the only RJ-12 connector around, lol. I don't see the sense in introducing yet another connector for one thing if it's not really necessary.

Found the problem

It's the cable chain

or not

ugh

[cedar depot]

I just use a telephone rj11

but now i have a utoc

[tiny bramble]

I'll search for some more telehone wiring. Couldn't find any last time.

[cedar depot]

@tiny bramble local hardware store should hasve one just need a tele phone cable only nee the twp pair red/green

[tiny bramble]

Found some on a shelf. 🙂

Have a new cable, but not sure the pin order is right on it

Still doesn't work

[cedar depot]

@tiny bramble octopus pro uses the two middle pins only

[tiny bramble]

Yep

[cedar depot]

sb2040 ?

[tiny bramble]

EBB36

[cedar depot]

ahh dont know that one Id have to look it up

Anybody have the 3do nozzle cam

trying to fix the blurryness

[tiny bramble]

No idea on that one

[cedar depot]

I have the Barfs on the tool head wonder if i solder the white leds that came with the cam if that would work better or will it kill the barfs leds

[tiny bramble]

Does the cam need to be focused?

[cedar depot]

fixed focus github says

guess Ill reach out to kb-ed

[tiny bramble]

So this EBB36. Starting from the beginning. Clipper reports:

Created a socket
mcu 'can0': Wait for identify_response
Traceback (most recent call last):
  File "/home/pi/klipper/klippy/serialhdl.py", line 68, in _get_identify_data

    raise error(self.warn_prefix + (msg % params))
error: mcu 'can0': Serial connection closed
mcu 'can0': Timeout on connect

Over and over

[cedar depot]

I had that error too

[tiny bramble]

Ifconfig shows CAN interface is up, I can see the MCU on lsusb, and it throws a different error when it can't talk to the CAN tunneling MCU.

So MCU is talking, it seems like. I found a break on the old CAN wire, which explains why the EBB36 was not connecting before, but not why it does not work now.

[cedar depot]

Try a different wireharnes

[tiny bramble]

That's the thing, the old wire is out of the loop. Made a new one. Continuity restored (I checked).

Also double-checked the pin order.

EBB36 does have power.

[cedar depot]

Reflash it ?

[tiny bramble]

did that earlier today to set it to 250,000bps

[cedar depot]

mine is like 10000

100000

typo

[tiny bramble]

hmm

[cedar depot]

https://wiki.kb-3d.com/en/home/btt/voron/BTT_EBB36

Step by step

[tiny bramble]

why is lsusb hanging

[cedar depot]

Strange prime line looks good but nothing sticking to the bed

Reboot ?

standard deviation 0.001718

[tiny bramble]

why not

so lsusb hangs when it's connected to the MCU

and fsck me. it doesn't see the mcu again.

swapped cables and it seems the mcu. Let me get another cable that is good quality.

[cedar depot]

ok

[tiny bramble]

ahhh got it. MCU hangs if you disconnect it from USB, so have to reset.

okay, so that solves one problem.

back to hanging while trying to talk to the ebb36

[cedar depot]

follow he guide I poseted

[tiny bramble]

I have a similar guide already open that's specific to the Octopus. I'm well past the initial config, though. This printer has printed for hours before.

[cedar depot]

Understand

[tiny bramble]

I'm torn between trying to resolve it and tossing CAN out the window and testing it with USB instead.

[cedar depot]

had to replace mine

[tiny bramble]

USB connectors are just not meant for this application. I wish I could use the CANBUS pins for serial. 🤔

Also, chain rated USB cables are stupidly expensive.

[cedar depot]

yea

Im running a USB cable for the nozzle cam in the chain

[tiny bramble]

oof

[cedar depot]

hopefully it last

[tiny bramble]

Here are my serial options and the pins. It looks like I could PB6/PB7

PD8 and PD9 are also options, but they're being used by BLTouch

Mrm. I dooooo have four spare wires run to the toolhead. I could do this without messing with anything yet.

[cedar depot]

nice

[tiny bramble]

ummm one sec

[cedar depot]

@tiny bramble

[tiny bramble]

Dang, that is fuzzy

[cedar depot]

recorded from phone on pc monitor

was looking for a screen capture app

maybe it would look better

[tiny bramble]

fair point

[cedar depot]

got it with snipit live video capture

Tweaking offset now hopefully i cna get a good print

cam a little low

Need to get a scrubber

[tiny bramble]

Yeah. Doens't look so bad now, though

[cedar depot]

Yea need to get some vhb tape

cam not staying in mount

[potent stone]

so you are giving up on canbus? didn’t you get it working at 250k?

[potent stone]

nice, is this on a sb or eva?

[cedar depot]

sb

[tiny bramble]

nope. 250k did not work. 😦

[potent stone]

what hapoens?.. let me read 😓

[tiny bramble]

my build log hasn't been the most detailed lately, so there are probably gaps. 🙂

[potent stone]

maybe it’s the ebb, have you considered trying another one? the thr36 is cheap, and if it works you can retry/return the ebb?

or another ebb if that’s at hand (🤭)

[tiny bramble]

that could very well be. I do have another ebb...but i'm about to switch to working on that machine.

Also I want to test if serial works.

I doubt it will, but it'll be fun

[potent stone]

it’s definitely not the config because if it works and than it goes down, it means something is off

it could be the canbus chip in the octopus, but you tried different mcu with the same results

[tiny bramble]

this is a new board 😦

I figured cable break

I did find a broken cable, but it may have been broken during the mcu swap

Also found a loose pin, but that only fixed it momentarily.

[potent stone]

the wires m could be, I had issue getting all the boards to show consistently at the beginning, I rewired and made new crimps and now it’s solid, even if I poke around on the connectors

[tiny bramble]

that's a really good point. and @cedar depot did prod me to try a different wiring harness.

[potent stone]

I’m recrimping and rewiring now… hopefully it’s as solid as I go by telling everyone it is

[cedar depot]

Crimping no fun

[tiny bramble]

I love crimping!

[potent stone]

you could try a minimal wiring setup, with the ebb right by the octopus with 4 small wires

[tiny bramble]

https://tenor.com/view/crimped-hair-90s-lizzie-mcguire-gif-13335576

[cedar depot]

Just picked up some new crimpers/ try crimping the usb nozzle cam connector

[tiny bramble]

Hmm. Okay. I'll think on my approach.

For now I need a break and then I want to try these new toothed idlers that just showed up

[potent stone]

oh yeah, one thing at a time

[cedar depot]

I need to adjust the voltage for the PS for the PI getting under voltage

[tiny bramble]

Morning

In a few here I'll start on Oscar and his idler issues.

[tiny bramble]

HA! I think I fixed it.

Once again removed the X joint without removing the belts. Kinda weird, but works.

https://tenor.com/view/leslie-jordan-leslie-belly-dancing-belly-dance-dancing-gif-25526487

After this print finishes (assuming it does) I'll switch filament and start printing a test body for the next OmniBox release (again/finally).

Nope, wait, gotta do input shaping and tune the belts.

TODO:

1. Oscar: Install new toothed idlers and cross fingers
2. Big Bird: figure out CAN issues:
   • slow down to 250k from 500k
   • reterminate Molex MF3 if that fails or sub out cable chain wire
3. Oscar: tension belts and tune
4. Big Bird: test belt alignment resolution.
5. Big Bird: figure out best way to add more wattage to the system

[cedar depot]

Cant get anything to stick to bed at all

[tiny bramble]

What are you printing?

[short cove]

Done that a few times too, works though!! Always good when a printer is back to printing.

[tiny bramble]

TC was the one that told me it was possible. I wouldn't have believed it.

Turned out to be much easier than I expected.

[short cove]

I just looked at it and thought it will work or I just have to rerun the belts anyway and gave it a shot lol I also done this with changing the front tensioners.

[tiny bramble]

Fair point. What could go wrong besides the belts get messed up?

[short cove]

Found my belt issue too, my left idler is on the piss so it makes it rise up and down depending on direction

[tiny bramble]

I had the same. My gut told me something was up with it, but I kept finding other things.

And I ignored my gut, because, why, how can THREE things be broken at once?

[tiny bramble]

Prints are looking good enough. Going to do a full day/full bed print because I need to do one and it's a great test.

[tiny bramble]

Aside from a little trouble getting the z offset right (hard to see the nozzle on the Dragon), looks okay

[cedar depot]

yea I have that trouble too

[tiny bramble]

And we're back to having kinematic issues.

I wonder if the pulleys lost alignment with the d-cut on the stepper shaft (when they were loose)

[tiny bramble]

Big Bird: Bypassed the cable chain; no luck

BACKGROUND FOR THE BYSTANDERS

Big Bird:

• original Merc build
• Ender 5 Pro
• custom Dual Z
• EVA 3/E34M1
• electronics in an OmniBox
• working on enclosing it
• currently having CAN issues

Oscar:

• new Mercury One.1 build on an Ender 5 Pro
• standards Z
• EVA 3/E34M1
• electronics in an OmniBox
• enclosed in a custom enclosure

[cedar depot]

Going to buy a USB cam ..nozzle cam dead came out of slot popped inside of SB toolhead from slamming ( vibration ) around. Video feed went black and that is the end of it. Not buying another one

[tiny bramble]

Ouch. That sounds loud and unpleasant.

[cedar depot]

Yea fans are a built loud

Plus phone microphone makes it louder..

[tiny bramble]

If my resonance tests today end up funky, it's because I'm playing Tool very, very LOUD.

Wind is blowing like heck. Gonna storm today.

Prolly could tighten that up a bit

Good enough for now. Back to trying for a test print.

Oscar finally has a good first layer.

[short cove]

Feel like it would only help make things better!

[tiny bramble]

It's printing, so the influence is clear.

[tiny bramble]

Still merrily printing away!

[tiny bramble]

Needs more tuning, but still a huge leap better than what I've been working with

[cedar depot]

looks like you got it going

[tiny bramble]

Still is!

[outer wigeon]

I just got done finally getting my e5+ to consistently print mercury parts again 🤣 Im just gonna admit it, I'm too low on Adderall to try to scroll to the answer: What is the advantage / pros of rolling the dice on printing the eva 3 stuff vs eva 2 (I can always do over with the other, just looking for an easy decision point for what to queue up for the next 19 hours

[tiny bramble]

It's a coin flip, TBH. EVA 3 is, IMO, more serviceable but also slightly heavier (~20g).

Oh, and E34M1 is fully documented, which is helpful.

[outer wigeon]

what's the blocking difference with Eva 4 anyway? belt/rail config?

Bingo can't beat that. I remember being like "woah, this is some solid markdown on this GitHub"

I ask on Eva 4 because I ran across an Eva 4 tool changer mod thing

[tiny bramble]

EVA 4?

[outer wigeon]

isn't the latest 4x?

[tiny bramble]

3.0.2, I believe

[outer wigeon]

Well. then... let's hope it was just a sleep deprived illusion

[tiny bramble]

Stock EVA has the belts run around both sides of the extrusion (2 in front, 2 in back). The big difference is in the belt catches and adding a couple mm between the belts and extrusion.

[outer wigeon]

honestly the less I think about trying to add any more complexity or features to my first damn nontrivial printer build, the better

[tiny bramble]

Stock EVA 3 also has built-in belt tensioners that take up a lot of room and suck. That back green thing is part of EVA 3 but not E34M1.

[tiny bramble]

That's fair. I'm tired of fussing and just want to print now.

[outer wigeon]

I don't make eye contact with the unopened box of hardware for a 12 filament ERCF lately.

not for months.

[tiny bramble]

LOL

I'm that way about a few boxes sitting on the floor here

[outer wigeon]

for reals. if anything my next actual practical step will be some dead simple means to push open an enclosure door, squeeze the wham bam bed to flex it (pop off the parts) and clothesline the print into a bucket. if not just tilt the whole damn printer and let gravity take care of half the issue

trying not to think of the automatic nozzle changer idea. must. finish. SOMETHING

but seriously though you'd think that would already be a thing right

I can't believe we still use our meat hands. if you look at them long enough and high enough they're actually really really weird.

[tiny bramble]

Meat hands! LOL

I almost gave up on these two Mercs. Until I got Oscar running yesterday, I was pretty f'ing fed up.

[outer wigeon]

I'm doing two too!

[tiny bramble]

Twice the madness!

[outer wigeon]

you should have seen my face when I noticed the third shims. I'd assembled everything, headsets and all, and just dragged myself back to slog through finishing this half a year oddessy

my consolation is that going through this is teaching me a lot more along the way (CAD, mechanical engineering, electronics, hell robotics even) than if I did what is increasingly obvious that would've been likely the more practical choice of buying 10 ender 3s

[tiny bramble]

Wait, we're being practical here? 🤣

[outer wigeon]

well if the aim is like printing all the merc parts in a few hours right?

[short cove]

@tiny bramble just wondering if there ever could be an issue with the screw on the tension towers coming loose? I was thinking of putting a locking screw in the top.

[tiny bramble]

Should not be. The belt keeps it under constant tension.

[outer wigeon]

I know I wouldn't be happy that way either but I def see the value of building an array of simple printers out of all the parts I've got laying around now

[tiny bramble]

I have enough spare rods and steppers and extrusions that I really want to build something unique. But time, money, etc...

[outer wigeon]

bro I maxed out my Amazon card buying everything remotely robotic and mechanical and sensor or anything, Jetson nano, rpi, tof sensors, a dozen of every kind of stepper,

all because I know if I get a cool idea,

and I get it cadded up

...and then gotta wait for parts, that's the end of it right there 🤣

"ask him what he's made with all that crap over the last year of hoarding, also, every tool imaginable down to a mig welder, all in a small 2 bedroom apartment driving the wife crazy as walkable space continuously shrinks"

WHO SAID THAT

[tiny bramble]

One of my best moves was organizing all the shit I bought since my journey started. Much space saved, much insanity prevented.

[outer wigeon]

darting eyes I.. I've made .. proudly gestures around him a MESS. that's what. and that's something

I'm doing exactly that right now. I labeled every drawer and .. plastic bin organizer array thing, and have in an excel sheet exactly how many of what is where, how much they cost, link to buying more.. next step is, you know.. not .. having these bins in the hallway. in front of the TV. beside the couch.

[tiny bramble]

If you wanted to put a lock washer in there, I'd recommend a regular washer underneath. That would be worth a try, methinks.

[outer wigeon]

felt like I had to empty the office lab room or I couldn't put everything in there compact so its all out here

[tiny bramble]

Ah, the relocation problem. It doens't belong here, so where do I put it for now?

[outer wigeon]

if you got tips, throw em at me now or later as you remember em

[short cove]

the belt tension seems right, i dont think ive had any issues and its getting vibration from the righjt pulley pin being on an angle and hasnt come loose

[short cove]

boxes that you sort later

[tiny bramble]

If you don't have an immediate storage, it goes in the "sort later" box

I have a sort later box and a sort later screw bowl

[short cove]

my room for my pc and print was a absolute mess

[outer wigeon]

it's too far for that, like those puzzles where you have to slide around the empty square to solve it

[tiny bramble]

Sort into place. If it's going in the office, put it there. If it's not, put it in another, less full box. Eventually, you will have fewer boxes and much more sorted.

[outer wigeon]

a year ago I had the perfect home office music studio.

[tiny bramble]

Damn, nice

[outer wigeon]

LOOK WHAT IVE BECOME

it.. it all started when ... WIDE EYED POINTS AT ENDER 5+ YOU!

yes, that's a salvaged DESK someone threw away at the dumpster broken down for stock fiberboard IN CASE I MIGHT MAKE SOMETHING FROM IT????

a broken $50 students computer desk?!!?

ok for reals though now that I said that out loud I'm throwing that out tomorrow that's just ridiculous

[tiny bramble]

Gotta start somewhere with stuff like that. It snowballs if you let it.

"I'm throwing this out...oh, shit, that goes too..."

"Might as well get a box."

[outer wigeon]

it's...I believe I've hit that point

[tiny bramble]

"Huh, I have four boxes now. Dumpster!"

[outer wigeon]

I've had this welder for over 7 months

[tiny bramble]

A storage unit is also a possibility for anything you might need later, but not now

[outer wigeon]

you're the second person to suggest that. you know what... im going to look at prices in the morning.

[tiny bramble]

Sweet. Sounds like you were ready to make some decisions and changes already, then.

We had our floors redone about a 18mo ago. Had to do a lot of keep or trash thinking then, too.

[outer wigeon]

what'd you end up doing generally?

[tiny bramble]

Boxes. Store, trash, sell. Sort, then resort.

Sort going into storage, sort again coming out.

Judiciously trash stuff

[outer wigeon]

clutches things

[tiny bramble]

I also stayed super stoned during the process, FWIW. Kinda abstract the thinking process and remove attachment.

[outer wigeon]

So you used a storage space of some kind to buffer things out to make it more processable?

[tiny bramble]

Yep. Since everything had to go out during the floors, sorted into boxes, stored, then resorted coming back out.

Two stages of trash/sell

I mostly ended up trashing stuff I forgot I had and saving newer stuff.

[outer wigeon]

I talked my Dr into giving me a lil Xanax Rx ("so I can nap midday despite Adderall, for biphasic sleep"), it might be the trick. I used to smoke every day, it totally turned off the addy and all the good stuff. then one day a switch flipped and one hit and I'm like AAAAAAAAHH-H thinks of everything ever did wrong in my life AHHHHHHH

I dunno what happened lol

[tiny bramble]

Caution with the benzos. That stuff can really mess with your system.

[outer wigeon]

absolutely.

In fact this is the last Rx I'm filling. it's the minimum dose you can get but I've seen the Xanax zombie people. the dependents. then there's that link to alz

[short cove]

ive got a tig ac/dc welder that ive had 3 years and havent even turned it on yet. it was welding for my car and aluminium

[tiny bramble]

😦

[outer wigeon]

sigh I guess im left with "diet and exercise" rolls eyes

[tiny bramble]

I got a cat to help me with work, and it's still sitting sleeping. Definitely a wasted investment.

[tiny bramble]

I think that's a lot of us...

[outer wigeon]

oh I'll be fine, I'm living at least 2,000 years. if I want to. we're all gods playing a video game anyway who cares

[tiny bramble]

lol

[outer wigeon]

I'm literally going to write "& jonspaceharper" on a card when she's shocked with a suddenly hers again dwelling for her houseiversary reunion. Thanks bro 🧙‍♂️🫵

[tiny bramble]

AWWW

Good luck, dude!

[cedar depot]

Print in place Dragon failed

[tiny bramble]

Booo

[cedar depot]

there must be something wrong with this printer

Think I might give orca slicer a try

[tiny bramble]

I've heard it's good

[cedar depot]

yea 2 failed prints with SS

I'll just user the defaults in Orca and see what happens

[short cove]

i used voron trident stock and it was good, just fine tuning really

[cedar depot]

drop and print no setting changes

[tiny bramble]

Oscar is still going strong. This is so exciting.

[cedar depot]

Mine is junk

for now trying out orca defaults to see if it does any better

[cedar depot]

Orca slicer pretty sharp

like how it interfaces with klipper

[tiny bramble]

Might have to check that out, then

[short cove]

Yea it has a device tab, makes it very neat. Plus you can just slice and send to your printer.

[tiny bramble]

Gonna check that out for sure, then.

Just skip SuperSlicer and Prusa Slicer, I guess? Debate's over.

[cedar depot]

Thats up to you

[feral prawn]

I ended up moving from cura to prusa, I wanted to go for orca but the lack of proper linux support killed it for me

[tiny bramble]

Hrm. Didn't think about that bit. My back office PC is a Linux box.

[cedar depot]

yea I tried printing in orca too just a test square its printign a diamond

doesn't make sense

[cedar depot]

removing the voron bed its so warped it can print anything

funny from a bed that doesn't move

[cedar depot]

hahah shimming PEI with paper to better bed leveling

anybody own a 3d scanner. Dad ants to get one and I have no experiemce with one at all

[feral prawn]

@cedar depot check photogrammetry

[cedar depot]

@feral prawn he was looking at the new creality ferret model

[feral prawn]

photogrammetry is not a scanner itself its a technique, afaik works with regular photos

[cedar depot]

@feral prawn told him not going to happen. He dropped it

[tiny bramble]

wtf

it's not printing again

More specifically, it does not move on the XY plane

Motors just grind

Even just homing does not work

It's the A stepper

[tiny bramble]

Checked connections and continuity

And now it works. 😠 Loose connections are sus connections.

[cedar depot]

@tiny bramble awesome you got it working. Me tuning trying to figure out why z offset keeps changing on voron after every print....

@tiny bramble maybe probe going bad

[feral prawn]

@cedar depot auto z?

[cedar depot]

@feral prawn no running quad level mesh every print but when laying 1st layer have to adjust every z offset every time

[feral prawn]

hmm I'm not much into how voron ia usually built

[cedar depot]

@feral prawn Ratrig / zero G ?

[feral prawn]

more my thing

thought have yet to build a rat

what are you using for z home?

[cedar depot]

Yea I have zero g top runs great no z adjust hardly ever

Inductive probe

Thinking about buying thr beacon

[potent stone]

I don’t know, it looks cool but also overkill and somewhat fragile for something sitting under the toolhead, klicky gives me much more confidence

I have read about a light sensor that might also be used for PA and other auto tuning… that would be cool

[feral prawn]

isn't that what bambu claims to do?

[potent stone]

https://youtu.be/c1hrP0gduRU

[potent stone]

yes, but with a laser and a nozzle camera

[cedar depot]

I'll have to check that out

[potent stone]

it’s pretty rough, but I think something slick from vendors might came out

[cedar depot]

I'm just checking it out

yea its rough

[tiny bramble]

Hi. I want a third working printer.

Do I order a new toolhead pcb?

or continue troubleshooting...

[tiny bramble]

Sweet. Someone's selling me an Ender 3 build plate carriage so I can go dual Z on another printer.

[cedar depot]

@tiny bramble nice

I have a cr10s I might switch to a switchwire

[tiny bramble]

Eh, I'm not super big on the switchwire.

I know it's faster, but it's still a bed slinger 😕

[cedar depot]

True

[tiny bramble]

Ordering extrusions will run $45 with shipping-ish.

Hrm.

I'm gonna hold off on this until later, though. I want to get Big Bird working first.

[cedar depot]

@tiny bramble 1ST Benchy on voron @44mm/300mm sec

[tiny bramble]

Very nice

[cedar depot]

Next will be the omniron case for the zero g

Hopefully I will get a good print

[feral prawn]

ditch it

[tiny bramble]

Not mine

[feral prawn]

ditch it anyway

whoever owns it will thank you later

[cedar depot]

Ditch what

[tiny bramble]

The CR-10. @feral prawn is also not a fan of bed-slingers, but I believe he may be more vocal about it than I am. 😉

[cedar depot]

Oh I see

Yea I have not used a bed slinger in years

[feral prawn]

I'm just honest and outspoken on what I believe

[cedar depot]

Put bed rails on it already though cr10s

[tiny bramble]

Pshaw, what? I refuse to believe this absurdity.

[feral prawn]

same thing if I don't like someone

[tiny bramble]

Napalm?

[cedar depot]

Need to put the cr10s back together and sell

Upgraded ezboard v2 ezabl 18mm sensor/bed rails

[feral prawn]

nah just gasoline

[cedar depot]

Plenty of users that will need a 3d printer

No reason to just ditch/ blow it up

[tiny bramble]

They're good starter printers

[feral prawn]

what i meant for ditch is get rid of it

sell, blow up, break it into millions of tiny pieces

up to you

[cedar depot]

Lol

Yes they are good starter printers

[tiny bramble]

Hopefully I got the extrusion multiplier tuned on this print. I'll see in a few hours.

[feral prawn]

just tune with ellis guide

faster

[tiny bramble]

I've got it open

🙂

[feral prawn]

that thing is my bible

[tiny bramble]

You and Vengeful harping about it made me finally break it open. It's pretty spectacular.

If...vibrant in color.

I'm finally going to look into extruder backlash

[feral prawn]

took you a while

[tiny bramble]

This is quite valid criticism.

I spend way too much time making stuff and not enough time making it look correct.

[feral prawn]

I'm kind of the same

[feral prawn]

I only do full calibration for stuff I'm selling

when it's for me is a good enough basis

[tiny bramble]

Speaking of which, I think I got the flow/EM right.

[feral prawn]

pics pls

[tiny bramble]

Retraction/prime is still a little off, I think.

[feral prawn]

adjust PA and retraction becomes nearly useless

[tiny bramble]

That's why I think it's too high. It's 0.5 but might be able to go lower.

[feral prawn]

I have a standard of .5 at 40mm/s that I enable for oozier filaments

[tiny bramble]

basically the problem is the bottom right. When it starts a line, sometimes it doesn't immediately adhere. Maybe that's not retraction and priming though.

[feral prawn]

sometimes its a little oozing that causes that

retract a little more maybe

[tiny bramble]

I'll fuss with it, i.e. run tests

But for now I'm hungry AF

[tiny bramble]

It'll be fun seeing how well this fits.

[feral prawn]

17h

if it fails you waste more

[tiny bramble]

As long as the first layer succeeds, it'll be okay

I'm not worried about failure outside that

[feral prawn]

I like your confidence

enclosed printer?

[tiny bramble]

It's enclosed, but the door is open

It's finished a 24 hour and a 20 hr print already, so I trust it to run for awhile

[feral prawn]

heh I printed the tops for.mine enclosed door closed

[tiny bramble]

Good heavens

How hot did that get?

[feral prawn]

did not measure

but it was a 6h print or so

and there was a 120mm hole open

[tiny bramble]

Ahhhh

[feral prawn]

but it got hot

but not for long

fan will go in place soon

[tiny bramble]

Have the stuff for the exhaust duct already?

[feral prawn]

it will be wiring week

just need one adapter from 100mm to 70

for the window

because I'm dumb

and printed something downloaded without measuring

[tiny bramble]

Oh, 70mm duct?

[feral prawn]

a big window funnel

page said it was 100

its 70

[tiny bramble]

Window funnel, lol

"It's an exhaust clamp!"

[feral prawn]

remember english is not my native language 😅

[tiny bramble]

I wasn't picking on that. I found the mental imagery hilarious.

How does one explain this thing? Call it an exhaust clamp. 😆

"You can't adjust it." "That's a design flaw! I'm sensitive about it!"

[feral prawn]

https://www.thingiverse.com/thing:4148187 it's not this one

but kigjt print this sometime in the future

[tiny bramble]

That one looks nice

Can maybe put foam in the window crack?

[feral prawn]

it's a tilting window now

at first it was sliding

[tiny bramble]

American windows [edit: in suburbia] are all identical. They all slide up.

[feral prawn]

never saw those here

sliding here means to the side

[tiny bramble]

I'm googling why it's that way and can't find an answer.

[feral prawn]

because 'MURICA! ?

[tiny bramble]

If that means "mass production of identically-sized windows reduces costs without an equivalent lowering of price," the answer is yes.

[old marten]

That is not true at all

Case windows crank out

And most of mine slide to the side

[feral prawn]

found the one I printed https://www.thingiverse.com/thing:5436726

[tiny bramble]

It's extraordinarily uncommon to find that here. I guess I extrapolated too far, but I also rarely encounter them where I've been.

How far north are you?

[old marten]

Mn

[tiny bramble]

I often find differences in building standards relate to climate. That would make sense. I'm in Texas.

[old marten]

its more to do with window size

wide windows slide to the side

narrow window cutouts, slide up

my living room has a 6 or 7 foot window opening, for a single window.

new houses built around here get similar sized windows installed in the main living space.

[feral prawn]

so 2meter window ?

[tiny bramble]

I've seen those but they don't open here. Unless it's a patio door (which goes sideways, of course).

[old marten]

one big center window, 2 sliding panes on either side

original window was 3 vertical sliding windows?

replaced with modern windows maybe 5 years ago.

[feral prawn]

widest I got here is 1.7m wide by 2m tall

here as in, my house

[old marten]

just measured it again, its 8 feet lol

[tiny bramble]

Good lord

[feral prawn]

ohh me likey

[tiny bramble]

This is not a patio door, though?

[feral prawn]

almost 2.5m love it

[old marten]

nope

[tiny bramble]

wow

[feral prawn]

I want one of those when I grow up 🤣

[old marten]

I get a great view of that canadian smoke today

[tiny bramble]

Oh that is lovely

the construction around here is all the same. You might find a high window like that, but it's usually in an older home or a custom built one.

[short cove]

my job is for a window company, our domestic sliding windows (side to side) can do 1500mm high x 3010mm wide. but thats slider (25%) fixed (50%) slider (25%) or 4 equal with with fixed slide slide fixed opening from the middle. Our commercial windows can do almost sliding door sizes as windows. we have done doors as windows as people wanted massive windows before. biggest doors we have done at the branch i worked at was 3000mm high by 1800mm wide per door panel, had 11.52 special laminate in them. they were 250kg per panel. Architectural houses are insane and have some crazy stuff!

[feral prawn]

1800 wide door sounds nice

[short cove]

they were 5.4m wide in total, 2 sliding and 1 fixed

so when open it was about 3.5m opening

[tiny bramble]

Makes me think of the giant sliding doors at natatoriums.

3m wide heavy-ass doors that lift to vent the chlorine fumes and keep cool in summer.

[short cove]

these were just balcony doors lol

[tiny bramble]

Wish my home balcony doors opened to a natatorium

[short cove]

we do some high end stuff and alot of custom made size/configuration. but we also do custom made stuff too. our commercial branch made a completely curved bifold door with curved glass in it

[tiny bramble]

"What's on the second floor?" "Oh, a gateway to a natatorium in another dimension."

[tiny bramble]

That sounds amazing

Btw, found the EBB36 on sale, so I went ahead and bought another to see if that's the issue with Big Bird.

[short cove]

its a very unique industry but there is so much to know and learn, that is what kept me in it

when are you making a mini printer called elmo?

[tiny bramble]

I really would like to get into manufacturing in some way.

[tiny bramble]

https://tenor.com/view/schmoedown-kristian-harloff-headphones-throw-storm-off-gif-21225099

STARTING NOW

https://tenor.com/view/elmo-sesame-street-sesame-street-characters-eyelids-funny-gif-25654561

Actually that would be pretty cool. Maybe 150mm^2 build plate

[short cove]

there is a vzbot 150 now

with awd

[tiny bramble]

Elmo has the need. The need for speed.

I have the parts to make The 100 or whatever it's called, I think

[short cove]

this is a what the company i works for can do in a full commercial aspect, we did the curtainwall glass and also the aluminium sun shades

[tiny bramble]

That looks stunning. I love reflective windows.

[short cove]

thats just energy efficant glass

im going with that but in a grey with silverish shine for my enclosure

[tiny bramble]

Is that the super thick stuff?

Energy efficiency in glass is, sadly, not common in America.

[short cove]

that would be 12.76mm energy glass in that pic, so 6mm clear with 6mm energytech with a 0.77 slight green interlayer

we had energy standards come in and the building industry was like "that means smaller windows probably" with using energy glass they only got bigger

[tiny bramble]

Want. That would do wonders for my summer AC bill.

It's not bad compared to my neighbors, but still. I'd like to not have my blinds closed all summer.

About four hours left on the new OmniBox print. That's ridiculously fast; I started it 8 hours ago and it's both halves of the base.

[short cove]

thats looking tidy

[tiny bramble]

Thanks!

That's Oscar; I believe he's about done. Just tuning left.

And hopefully I can get Big Bird to work today, too.

[short cove]

so he isnt so grouchy anymore?

[tiny bramble]

He's never been a grouch, tbh. Oscar is pretty well-behaved. Not as nice as Grover, though. Grover just keeps printing.

https://tenor.com/view/bigbird4k-bigbird-bigbirdin4k-gif-20765964

Big Bird, however...

Shouldn't complain, though, cuz I got Big Bird for like 100-150$ used. Just needed a lot of dusting.

[tiny bramble]

EBB36 replacement came

gonna take a coffee break and start on that

[tiny bramble]

Big Bird is working. The old EBB36 was dead

[cedar depot]

I had to replace the sb2040 v2 now put a sb fan 3007 on it to help cool it

[tiny bramble]

Yeah I have a 3010 I need to put on there

[cedar depot]

It helps

[tiny bramble]

My nice, fancy, brand new EBB36 died instantly when I tried to heat up the hotend.

So, that's not gonna work anymore

[feral prawn]

WTF

I wonder if the heater pulls too much current and somehow it cant handle it

[tiny bramble]

As soon as I told it to heat up, died.

Made me wonder if there was a short or something

[feral prawn]

polarity?

wait doesn't make sense, board would not work or die before

heater has no polarity

unless heater is shorting

[tiny bramble]

Nah, wouldn't power up if that were it.

But it might be some other issue with the board that powering it up shorted something else or who knows

At least this one's in the return window

Update:

1. Oscar is printing and working. Unless something else comes up, this build log is back to Big Bird alone.
2. Big Bird blew his second EBB36, so I ordered an EBB42 instead.

[cedar depot]

Happy Fathers Day tomorrow to all the Dad's out there

[tiny bramble]

AND my gantry is square.

Not having a square gantry certainly explains the ringing. Getting it correct was a lot easier with the gantry lock bars, though

Which I will now use religiously again.

[cedar depot]

How do you get the graphs I ran mine but don't see the graphs

I use the alignment tool also

Got something going on. But not sure what it is

[tiny bramble]

https://www.klipper3d.org/Measuring_Resonances.html#measuring-the-resonances_1 <-- Here

calibrate_shaper.py

Then grab the png file it spits out

[tiny bramble]

I'm printing at ~3000ish accel, 100mm/s and it's coming out beautifully. Sweet.

(Infill and travel are at 4500)

[tiny bramble]

Show and tell coming today. Prints are square, smooth, and delightful.

[potent stone]

serial!!

you have 2 to claim 😜

[tiny bramble]

Unfortunately, it's only one printer being delightful. The other one is still waiting a new CAN board.

But yeah, I should get my serial soon.

I wish the printer wiring looked as nice as the enclosure it's in (the wooden one)

[potent stone]

well.. I’m sure your “bad wiring” is more than my best effort 😅

[tiny bramble]

It's not bad, just could be neater

Speaking of which, gotta go finish neatening up someone else's printer.

[tiny bramble]

I'm particularly proud that text in the second pic come out so clearly. Ringing is just gone.

[tiny bramble]

New Dual Z Mount

This uses the stock Ender 3 carriage to mount the build plate. These are easier to come by for free than the $30 worth of idler plates I was using.

I'd like the kinks worked out before switching Oscar over to dual Z.

[feral prawn]

Hail hydra

[cedar depot]

@tiny bramble which cslicer are you using ...super slicer giving me all kinds of issues

@tiny bramble thinking aboutswitching to pruserslicer

@tiny bramble parts are looking awesome

[tiny bramble]

Cura, lol

[tiny bramble]

Working on a coupler like the one @potent stone modified (or found, can't remember), but has a PC4-M10 coupler on both sides

[potent stone]

ohhh, I just also modified one to hold my umbilical wiring 😂… I like it a lot, as I’m fan of any print in place in general

[tiny bramble]

Me, too! I'm playing around with it to see how small I can make it, then maybe adapt it for somewhere else

I have an enclosure that this is perfect for

[potent stone]

I am trying to modify one to have an extra support… maybe I’ll send you the sketch, I spent 1 day in fusion and still haven’t figured it out

[tiny bramble]

I'd be happy to look at it

[potent stone]

So I made this cable guide, terminating with the "back ring", all the holes are for zip tight, I already printed it and it seems to work

[tiny bramble]

looks nice

[potent stone]

but I am struggling with the front piece, right now I printed it like this and it works (8.2mm hole, 20 mm higher, snug fit to my canbus wire)

[tiny bramble]

So wires will go through that?

[tiny bramble]

What part about the front are you struggling with?

[potent stone]

yes, the wires would climb to the back of the printers and pass trough there, but I want to reinforce the piece by also connecting to the to panel, where is solid wood (the back is not the stronger plastic, I'll add some plexiglass as well, but still...). So I want to add something like this

ops

I hope you understand 😂

[tiny bramble]

So extra screws holes that attach to the wood?

Ohhhhh where you want those screw holes, there is more wood

[potent stone]

yes, the thing is mounted in a vertical wall, the back plate of the enclosure, and the extra holes will grab on the top beam

I probably could have done this differently 😅

[tiny bramble]

Hmm. Tbh, you've got 3 M3 screws holding it in place. And I saw more screws holding the other side down. Are you sure you need more reinforcement?

[potent stone]

but I really like this wiggling stuff

[tiny bramble]
