>>2037750
I'll second the abl probe. I couldn't print shit with mine until I put a bltouch on it because the bed was warped like a potato chip. Also go ahead and swap to a silent board and switch the fans out to some quiet ones. Stock they are so fucking loud you will never want to use it. My wife was ready to throw out away when it was stock, now I can print all night and nobody notices.

>>2037807
doesn't the v2 already have the new silent mb from factory?

You guys have a favorite brand of PLA+?

>>2037750

No. I'm not sure why, but none of them come with it.

>>2037813
Actually I just double checked and it does. I couldn't sworn I checked before and it didn't. Oh well, strike that one off the list.

Do you guys actually use thermal compound anywhere on your hotend? I've read it should be used between the heat sink and heat break, heat break and heater block, heater block and nozzle, and even around the heater cartridge.

>>2037820
Only between heatbreak and heatsink, obviously cheapass $1 thermal paste, wouldn't waste good stuff like arctic on a 3d printer

>>2037809

>>2037831
Why? I thought the point of the heatbreak was to stop heat going upstream from the heat block, so why are you helping it to do just that?

>>2037746
I have a problem with my 3d printer, I installed the BL Touch on my Ender 5 pro, and now it acts like it wants to print in the damn corner!

>>2037867
it makes a sick grinding noise omg please help :(

Does S3D has an option to increase the infill for very small areas? Both Cura and Slic3r seem to do that by default.

>>2037862
because you want the cold side of the heat break to be as cold as possible, it needs to conduct as much heat as it can to the heat sink

>>2037871
Sounds like it's physically hitting something.
Can you kill the power and move it freely?

I don't use a blTouch or ender, but seems like some anon is going to say "z offset"

>>2037809
Supposedly an engineer for all those companies and he still can't be bothered to be able to seat a PTFE tube properly. Also, in what world is an Ender 3 V2 $400? Also interesting to see that he now thinks the printer is irreparably damaged.

A work colleague and I are in the process of specifying some parameters for a custom 3dp board he is going to design and I am going to write a Klipper port for. We've settled on the following specifications:
>12+ driver ports, compatible with the general stepstick modules.
The reason behind 12+ is that I run a 4XY 4Z motor + 1 extruder printer, but want to expand up to 4 extruders. We are also considering supporting a 16 driver config because we also want to suppport a hash configuration such as youtube com/watch?v=Lo-ymCO0Ekw and with dual motors per hash axis that would be 8 XY motors, which is kinda insane but making a slightly bigger board and a couple of headers and passives isn't that much more cost for a pretty expensive board anyways. There is a possibility of just having 2 board designs or a board + expansion.
>STM32H7 series MCU
We are going for the H7 series because, well why not, it's already a pretty insane board, and the extra oomph won't be a drawback. The model we will go for is not really decided yet but we are pretty sure we are gonna beef it up as much as possible. It will be a 168 IO model that is for sure.
>24V
Happy medium, enough said.
>Bed heater
If you are the type of person who will want this board you probably have a mains bed so nothing special. Bring your own SSR.
>BLTouch, Pinda support
>All the usual end stop ports
>Possibly dual microfit + standard molex connector ports since microfit is sooo much nicer.
>Support for 4 hotends with 5A per hotend which at 120W should be fine but I still have to check with the mosquito magnum+
>5V DCDC 5A (for the Pi/Pi derivative you will inevitably connect to it)
>12V DCDC 5A
>Probably 2oz copper pour so the traces can be a bit thinner
>LCD/TFT support not guaranteed not sure if we want to put it on there since people will most likely use a 20 dollar orangepi board with this anyways
This is the specs we got for now, any other ideas what would be nice on such a no compromise board?

>>2037939
I'd go with an OMAP instead.
You can use the PRUs for real-time shit.
While also having a full networked Linux environment that can run Octoprint, a slicer, and klipper.

>>2037941
Fair point but you lose a lot on compatibility with other firmware projects. Less complexity, less place for something to break, easier design etc. Pi boards have gotten so cheap that there is no real reason to run OMAP unless you want to really run all on the same board. And introducing that would rule out a lot of people from wanting to run the board on marlin "normally".

Are there any advantages to this set up? It seems that there is a main wire or ribbon that runs somewhere and then from there, you connect these boards to the various axis and hotend. Is this sort of thing compatible with any printer or specifically just this one? Seems like a neat idea to control the wires. I think the CR-10 S Pro does the same thing but I could be wrong.

>>2037985

So a friend wants me to print them a fish. Any ideas on what filament I should use? I was thinking some sort of wood filament but I don't have any so I'd have to buy some. I'm also not sure on what model to use, they are an avid fisher so maybe a trout or something.
When printing wood filament, if I vary the temperature between layers, can I get some nice looking colors?

what exactly are you trying to do? improve your interlayer adhesion? you could try printing a temperature tower and then do a destructive test to see what temperature makes the best bond.

Up to 150 GPIO used in the design right now, it's gonna be tight. That is for the 16 driver model, 12 driver is at 122 GPIO. Do you guys think a screen port should be included? If yes it should probably be a TFT screen as most of those only require RX/TX. We don't think we will include expansion ports really, probably won't have any extra gpio left in the end. 6 GPIO for an ESP8266 also seems like a waste but if we have pins left I guess it could be useful.

There's no way the inside will get hot enough to ignite cardboard, so the only way it'll catch on fire is if the printer itself catches on fire first and ignites the cardboard.

It's hard to account for irregular shapes. Also, people don't stay perfectly still.

>>2038727

>>2038726
All those printers if built correctly are very reliable but that requires skill and money which not all people have. The annex I would put at the top, voron below, and hevort at the bottom for reliability. I'd say a prusa is between an annex and a voron but in capability it's kinda sheit. If you want something that just works TM get a prusa yes. But the second you try printing bigger and faster or larger or with non PLA filaments you are going to be missing out on a prusa (yes you can print ABS on a prusa with an enclosure but print quality won't be nowhere near as good as a proper insulated chamber like on the Annex K2.
Let's face it, prusa is an "Apple" product. If you have money to throw away buy it, if you don't want the best but just the easiest buy it, but if you like the hobby and like learning, build something else.

I've been running pic related setup with a shitty printed pulley for almost a year and there is very little wear on the belt. Belt is some cheap ass chinesium shit from Ali.

i've been having trouble getting my ender 3v2 to print well after switching to the micro swiss all metal hot end, and now i notice that the nozzle temperature is getting way too hot than what i set the temperature at (for example i have the temp set to 195 and it would continue rising) until it gets to 260 C and gives a continuous beep along with "nozzle temperature too hot" message. did i fuck something up?

I upgraded to a 48mm stepper for increased torque, but with the original bracket the bed carriage would hit the motor.
The printed one is longer so the stepper clears the bed.
It looks funny with that bevel at the base but it was required because it's ABS and it would bend when tensioning the belt otherwise. There's also some bracing on the inside to make it stiffer and the extra holes allow easy access to the screws.

>>2038872
>I upgraded to a 48mm stepper for increased torque, but with the original bracket the bed carriage would hit the motor.
i also did this, but my solution was to take a hacksaw to the y carriage.

>>2038750
I wouldn't be too sure about it being a PID related issue. To my knowledge, the heater block is similar on the Microswiss to the stock Ender 3. I switched from my stock CR-10 heater block to a Slice copperhead without issues. I still tuned the PID after, but it was functioning fine without doing that. Given it's a completely different material, some copper alloy, and the shape is a fair bit different, plus I switched heat break to titanium, nozzle to hardened steel, and a different heat sink, I couldn't see your setup change giving an overshoot of 65°C. I'd probably look into replacing your thermistor, they're cheap anyways.

If you plan on doing high temp filaments anyways, it might be worth picking up a PT1000 (not PT100) since it doesn't require an amplifier like the PT100. Just plugs straight into your existing thermistor port, and you need to change the value for your hotend temp sensor in the firmware. If not just pick up a replacement thermistor for your existing one.

>>2038718
Is that through Inkscape?

>>2038875
While hacksaw is cheaper it's quite brutish for my tastes.
For me this was a good exercise in part design. I made the first version with just 3mm walls all round, no extra reinforcements. It worked but tensioning the belt would also make the bracket bend, also the holes on the opposite side of the motor were too small for the screw to fit through. Knowing this I revised the model and ended up with what I showed above.

>Whatever's cheapest at home depot.
Will likely not even be accurate to 0.1mm, although confusingly, it will display to 0.01mm (or the nearest imperial equivalent). May be fine for your purpose, but may not. For most FDM 3D-prints it's mostly fine, but do note that battery life on the cheap ones is garbage and this may cause bad readings.
https://www.youtube.com/watch?v=KnDype-j3hk

>Mitutoyo. Starrett and Brown and Sharpe are also good.
Either of these will likely read to 0.01mm (or even 0.005mm) but will only be accurate to 0.02-0.03mm, which may cause fuckups if you really need them for that kinda accuracy - so use a micrometer for that kinda gig. Brand name units like these are usually overkill for normies, but I've got a pair of TESA's myself and they are great.
My advice: look at second hand dial calipers from a name brand. Cheap as balls since most machinists have ditched them for digital calipers, but the battery won't run out and they're usually just as accurate than digital units. Also, nobody will nick them because reading dials takes effort.

Damn these are way more expensive than I was expecting. Also, why do you need an accessory to freeze the display with the Mitutoyo ones?
>>2039057
I would have assumed dials would've been more accepted by older machinists and thus be more expensive, I will check them out though.
Thanks anons

>>2039063
>Also, why do you need an accessory to freeze the display with the Mitutoyo ones?
I have never, ever, in my years of using digital calipers needed to freeze the display. If you really need to do that, you can hold the ORIGIN button to set the caliper's zero to the current reading, then close them and it will read, and persist through power cycling, the negative of whatever reading you saved. To reset, close the calipers and hold origin again.

Everyone has gone to digital calipers because calipers are not precision tools. Digital are far easier to use and are far more reliable, and it doesnt fucking matter when you are measuring to only .0005.

Buy knock off Mitutoyo calipers on ebay, youll be more than pleased with them.

a 99% tuned machine will still show belt ripple depending on the light, when printing straight walls parallel to an axis.
Roundish object tend to hide those.
all of the other common artifact you can get rid of with the right settings and careful assemble
>>2039179
is also poor lighting and piss poor resolution, not an ideal pic to brag desu

>>2039184
Just to show 4 days of print time don't show any obvious defects. Ender 3 is a perfectly fine machine

not to insult you, the rocket is well done

If everything is clean and new, pom wheels, etc and you print slowly I don't see any arifacting, ringing, "belt ripple". I think a lot of people run belts way too loose even with a tensioner

maybe you could make some rig that could clamp a person's arm down, scan their arm surface with a laser, and then lay the tatto on the scanned surface. It would probably only work good on arms though and be prohibitively expensive and still probably finicky. A tattoo artist can work on basically any part of the body which will bring in a lot more customers and be worth the long term cost of having them on the payroll. Keep in mind also that the best tattoo artists also make original art which also attracts customers who will pay more for their art. The only thing I could see making a dent in that profession is something like those pads they had in divergent where it sticks to their skin and prints something, but otherwise people will still pay good money for original art.

nothing says digital art can't be or isn't original. plus people copy tattoos all the time, even 100% original "unique" works, some douche will go get a copy.

the advantage of a printed tattoo would be consistency... no "OOPS" and no "yeah I know you asked for a rose but I was feeling this Venom dude you know" (which also happens)

I'm not OP but it's a thought I've had many times: how to make a tattoo printer. Technical difficulties aside, imagine the print fails!

Looking for a box style printer for improved rigidity and a larger bed, but I'm torn between a Tronxy X5SA and an Ender 5. CoreXY sounds cool but what really attracts me to the Tronxy is the fact that both Z axis leadscrews are on opposite sides of the bed. The Ender 5 with it's single leadscrew on the rear makes me concerned about bed droop.
Is the ender 5 design rigid enough? Is a coreXY printer difficult to set up for a first kit build? Are my concerns completely unfounded and should I just flip a coin?

>>2039265
>improved rigidity
you my friend want a delta. you won't get one of course. the corexy shouldn't be any harder to build and set up than anything other than a delta.

also you don't need a larger bed for a first printer, you've got maybe one thing you might print that might need the larger bed.

What acceleration and jerk settings are you faggots using on Marlin ender 3?

I'm mostly looking from a step up from the Ender 3 with the same or larger build volume. The Mac Daddy takes up the entire plate of the Ender 3 so I would prefer over travel.
I'll most likely end up with the Tronxy, the one I'm looking at comes with a probe so that's what I'll lean towards.

No, they read to 0.01mm.
https://ecatalog.mitutoyo.com/ABSOLUTE-Super-Caliper-SERIES-500-No-battery-or-origin-reset-needed-C1383.aspx
Mitutoyo says their calipers are only accurate to 0.02mm, which is mostly due to the geometry of calipers themselves. Harbor Freight calipers are undoubtably worse, and they say so on their website:
https://www.harborfreight.com/6-in-dial-caliper-63730.html
>Note: Specifications are approximate and subject to change
So yeah, their 0.001inch (0.025mm) accuracy rating is worth as much as the paper it's printed on. Even they admit it won't be accurate to 0.01mm.

>Cheap calipers are every bit as repeatable and accurate as high end brands.

>>2039692

anyways you can only print in one shade with a single pen so you have to loose everything that isn't a vectorizable line anyways
seems like a no brainer to vectorize

>>2039694
>wouldn't smooth lines be more suited to a CNC machine?
Your laser engraver can't do curves anyway. It's strictly X,Y in specific step lengths. So even your vector image gets essentially rasterized.

>>2039701
it's way more precise than most images

>>2039706
It doesn't make a difference in precision.
It can only move in a specific grid, no matter what you do. The smallest distance your stepper can move is fixed.

What can happen is stuff like a visible line patterns or Moiré effects. Which can be countered by adjusting the scan gap, scanning at an angle, etc..

Good point... The people that were complaining about their prints had what looked like verticle waves that went through the layers and were along the X and Y axis.

Serious question. Are 3D printed electrical junction boxes up to code (specifically burgerland)? I'm going to do it anyway for a splice I had to make today, and it's going to be buried in drywall, so it hardly *matters* but it got me to wondering what actually makes one of those plastic junction boxes "code".

>>2040088
No, not even remotely.

>>2040051
It is magnetic.
The other print pulled it right up like 10mm high in all corners.
All around the edges too.
All those clamps have done it perfectly and there's minimal warp to this part.
It now has a curved top so whatever

>>2040008
I've got one of these with stiffer springs and a magnetic PEI plate. I use manual mesh leveling and I haven't re-leveled in like 2kg of filament.

>>2040092
why tho?

>>2040088
> Are 3D printed electrical junction boxes up to code
"it depends".
>what actually makes one of those plastic junction boxes "code".
Electrical code is usually both easily googleable and highly dependent on location, e.g. you're not going to find standards related to saltwater flooding and basements in central Arizona but way more likely in coastal regions.

>>2040116
Oh I see what you are saying. That's some pretty serious warping going on then! Id proba KY use some flat bar rare earth magnets to ho, d the corners down, but I have those on hand. You could probably print some sort of corner bracket if you were so inclined.

>>2040118
I bought some of the stiffer sprints, too. I upgraded them already but they were just with hardware store springs. I think I will spray paint my new ones black and then print some fake springs to go around them so I don't fuck up my printer's color scheme. I'm hoping my bed actually gets level because when I make a topography map of it, one corner is always above or below the rest of them. I don't thi m it is warped, I think it's just the 4-points-on-a-plane thing.

AHHHH

Ended 3 pro. Was printing good, then bed level got ducked up. Leveled it again, and now it levels perfect after auto home, but then the print starts like 0.030 too high off the bed.

I leveled it at temp, and always double check. It’s very clearly stepping up when it’s time to print. Does it across all the models I tried. What. The. Fuck.

>>2040159
If you're using cura, there is a plugin that allows you to set a z offset. Otherwise, when you use a piece of paper to level, just make sure the paper gets grabbed a little more aggressively.

>>2040160
I will check cura. The paper has a slight amount of resistance, but the gap when the print starts far exceeds that thickness. I’d have to make it grind on the auto home to fill that gap

>>2040161
You may have fucked up your settings in Cura because the default is 0 (meaning it is exactly at the height that it’s homed to)

>>2040180
Haven’t changed any models since the last print. Two identical ones

So if I'm still getting little hershey kisses wherever my nozzle last is before it hops up, is it better to change retraction distance or retraction speed?

Right now i'm at 4mm retraction at 35mm/s

>>2040158
I was fucking with mine too much I think. 5 probes per point, 15 points per axis... It took almost 2 hours to probe the whole bed. I was using UBL. Then I see people just using a 3x3 right before they print and getting good results. I can't even say if the mesh I last built was good or not because I never got around to printing the validation pattern. The last thing I did was make the mesh points as small as possible (3x3) but confined that to 25mm in the center of my bed. I really just wanted it to be 4 points so I could do quick testing of the validation pattern. Anyways, I havent got around to testing that yet, kind of feels pointless since I am changing my carriage this weekend.

If you flash Marlin you can enable Z babystepping and just adjust it while you are printing your skirt or whatever.

>>2040217
I think retraction distance would probably be better. Only one way to find out. I don't know if you've done this tuning yet, but this page will generate some GCode for you that you can test and see what the best retraction settings for you are.

replace springs and fuck with it stock for a month
you'll see if you want other things.
if i had to say a must upgrade do the dual gear metal extruder. once you recalibrate your esteps (just look up estep guide on youtube) it works really well and is a hell of a lot more durable than the stock plastic lever one.

>>2040253
Ahh, I was planning to get that anyway, it seems to be a common combo on amazon for 25 $

>>2040139
I p much solved it by adding little feets to the model that end off a few mill below the layers where it starts adding top surface and begins warping. I just added the clamps on the fly. It seemed to be working tits but I had to step out and I'll find out how well it's working later today.
I was honestly tempted to drill holes in the bed and bolt it down to the bed but got lazy, then found the clamps at the store

>>2040159
Give each knob an equal twist, maybe 20° each.
360° is 1.5mm so do math

>>2040259
Don't get the red one unless you are certain that the bolt that holds the second gear is black and is a shoulder bolt. I thought I bought a good one but I got chinked and ended up with a regular bolt on mine.
There are two needle bearings that go over the bolt that the second gear sits on. On a shoulder bolt, they just spin because the shaft is round. But on a regular bolt, the threads will fuck up the needle bearings and that will lead to fucked up extrusion. Not immediately of course and it depends on how much you print.
If you want to get a decent extruder, look for a "bmg extruder". The BondTech is the original one but it's kind of expensive ($80+). The clones are cheap, I think mine was $16. I did get it on Amazon and the listing got removed soon after I bought it, probably because it was counterfeit... But, the good news is there are tons of them on there. Just search for bmg extruder, sort by reviews, and pick one out.

Printed at 0.1 with 0.4 nozzle for the first time yesterday.
Walls look amazing top layer looks like shit. Did no ironing.
Where did I mess up? What's the best shell settings to print slow but good?

Did you calibrate your extrusion multiplier?

Pretty sure I messed up when not using any top surface skin layers

>>2040356
>extrusion multiplier
Like in general or specifically for 0.1mm? because flow is calibrated

>>2040357
I would try ironing. Some nozzles make it look like shit but I’ve had good results overall. Maybe turn your retraction up a little.

>>2040366
Gotcha, going to give it another go

Has anyone tried using a 3d printer for scarification?
it seems like it would be pretty easy to mount a knife on one and carve something on your arm

Have any of you ran the OctoPi SD in a VM before? I can't seem to figure it out. I spent a few hours dicking around with it last night. Finally just gave up and went to bed when I realized I didn't need that specific file, I could have just used the regular Raspberry Pi OS and then manually installed OctoPrint.
>inb4 run octoprint natively in windows
I wanted to test Klipper.

>>2040389
I'd probably just use the hot nozzle instead of a knife. I have a gnarly scar on my wrist that I burned in with the wedding ring from my ex wife. Dumb ass move. I usually just tell people it happened from a welding accident.

>>2040402
That’s exactly how it works. After having fucked with Cura’s “jerk control” shit for a month straight, I found it’s better to leave it off and just regularly tighten up your chassis.

>>2040467
OctoPi runs on a Raspberry Pi: an ARM.
You can't virtualize it on an x86.

>>2040469
>just regularly tighten up your chassis.

>>2040389
uneven surface see all the tattoo discussion

>>2040469
I mean in the firmware you idiot

>>2040475
People make Raspbian VMs all the time though.

>>2040353
Print the top most layer slower than everything else. Also you want a good 3 or 4 horizontal shells on the top.

>>2040481
just use the bltouch to probe the arm and build a mesh first
maybe design something that keeps their arm in place so it doesnt move
laser scan their arm so if it does move its ok

>>2040467
What virtualization software?
Or just use a normal Linux VM and install it there, it should run on x86 just fine...

>>2040475
QEMU supports ARM hosts, apparently with support for raspberry pi hardware.

>>2040508
Why would anyone, who isn't developing raspberry pi software, want to do that?

>>2040582
I was trying in VirtualBox but just because I already had it installed.
Some people want to test the software out when they don't have a physical Pi. That's my reason for attempting it. I ordered one and it will be here this weekend but I'm getting anxious to use it.

>>2040591
>I was trying in VirtualBox
That can not work. Virtual box doesn't do instruction set emulation. So you can't run raspbian or any other ARM OS on it.

>Some people want to test the software out when they don't have a physical Pi.
You have to use something like QEMU to emulate Raspberry pi hardware.

If you want to try things out you either have to switch to QEMU, where you should be able to run these OSs or just install an x86 Debian (which is very close to Raspbian) on VirtualBox and install octoprint on that.

>>2040593
Okay well I will try QEMU tonight then. Most likely I will get the Pi before I figure this stuff out. I was just hoping to familiarize myself with the OS and the software before I attempted it live.

>>2040596
>I was just hoping to familiarize myself with the OS and the software before I attempted it live.
In that case just running x86 debian will probably bring you the most benefit. It should just werk with VirtualBox and is very similar to what you will be running.
If you can set up octoprint there you will be able to set it up on a raspberry pi.

the cr10 i got was fucked with by an idiot. how do I wipe and reflash the board and bootloader? ive tried chris rileys video but it says

Error: The program size (129894 bytes) is greater than maximum allowed (126976 bytes)

it has some TH3D marlin on there that doesnt respond. i want to wipe it all and restart the process. I want to git gud at this and never have teh same problem twice if I can help it.

>>2040684
if you can even attempt to flash it, the bootloader is fine, so don't fuck with it. download the firmware you want, open it in the arduino IDE, make any changes you need, and upload.

>>2040597
My Pi is actually out for delivery a couple of days early, so looks like I just wasted time trying to figure it out. Oh well, thanks for the info anyways.

>>2040330
>being so triggered about someone else buying something that you have to jump in and convince anons that it's a good thing™ that you cant afford something

>>2040596
>>2040597
You guys do realise octoprint runs just fine on a normal x86 linux, right? Just install it normally, start it up, and navigate to 127.0.0.1:5000 in your browser to explore all its wonderful menus.
