Allright. I took the plunge and bought the ender 3. Took all day because i missed a couple steps in the video i was watching. Put the wrong screw on the z axis drive but got the right ones in now. I finally did it and am proud. Even got the unit to home.
So now i have to aquire more items. What do you ender 3 owners use to connect the printer to your computer? Do you still have to manually print stuff or can the computer just load print and be done with the whole job eventually?

Didn't get any advice last thread. So I'll try again.
I'm printing in ABS now because I want to do some acetone smoothing and need heat resistance. Naturally, the ABS is shrinking more than the PLA I'm used to. I have already calibrated PLA with a 20mm cube. Should I account for the ABS shrink by calibrating the esteps again and adjusting them accordingly, or should I just scale my model up to account for shrink?

The TF card it came with

>Do you still have to manually print stuff
Yes, it is actually more reliable than having the computer stream the commands to the printer. The TF card is also faster, direct printing usually has missing steps and random gaps.

>So now i have to *acquire more items
The only mods I bought for mine are a geared extruder and a capricorn tube and yellow bed spring set, the rest I just printed. Make sure you properly leveled your bed, it shouldn't take more than a minute.
Also since you are new, your first prints should be as follows:
https://www.thingiverse.com/thing:2925230 Z-axis spacers.
thing:4220059 Hot end fix, you should do this as soon as you can. You will spare yourself quite a lot of headaches later on.
thing:3236093 Cutting jig for the hotend fix above, gives you a precise length tube with a precise cut for a flush connection.

Anything else can go after these.

I installed an all metal hotend onto my CR10. Now the hotend cooling fan is working too well and causing the molten filament that works its way up the hotend to cool and stop extrusion. Is there a way to lower the speed of this fan? Note: it's not the part cooling fan. Arrow is where the filament hardens. I already turned the temp way up, but it still happens.

I don't have a CR-10 but if your filament gets molten above the heatbreak in any printer, you've got bigger problems than "heatsink too cold". Filament where you've marked it should never me molten there.

In an all metal hotend, it's likely not actually melting in the heat sync, but pulling molten plastic back up during retraction. Some websites recommend 1mm of retraction, but if your model has small layers and lots of retracts, you'll probably need to halve that.

>What's print time valued at?

It depends on whether you are printing files you designed, or files the customer requests.
I only do the former and the files I design are specifically designed for reliable printing, so I charge $2 per hour.
Those that take requests or customer-provided models charge $3 to $4 per hour since there's more troubleshooting and upfront labor.

My prints have developed a weird wobble/gradual layer shift that only affects longer prints. Shorter prints that are near the same height are printing out perfectly fine. The bottom image is my last few prints in order they were printed. I thought it might be a filament being too tight issue, that's why I switched to the black, but got the same result. I'm stumped as to why length of print seems to be the main factor, if it was something wrong with the axis you think the shorter prints would have the same issue.

SD cards are protected by a full fuckteon of patents, IP rights, copyrighted content and all other possible prosperity blockers.
It was so bad that initially the SD Association even tried to ban all publicly-available SD-related stuff and keep the details secret from all who did not pay them a bazillion of dollars.
So basically "TF-compatibble card" means "SD card, but I don't want to pay a ridiculous cash just for using that name". Obviously, this does not bother anyone in China, but amazon or ebay sellers have to be cautious.

There is a bunch of other super-popular names that are in fact registered trademarks of companies or associations ready to launch their piranha lawyers to rip your guts to pieces if you dare to use their name without a permission. Such names include for instance bluetooth and wifi, and included I2C until its patent expired.

NO.
I've worked with a student who was doing a minor on growing bone cells (?) on 3D-printed components, with the intent of using a 3D-print as a bone replacement that dissolves once the bone has started growing (or something like that). We investigated the growth of regular bacteria as a starting point, and used various layers heights to change the Z-surface roughness, and sanding for the X-Y plane. None of it helped: no matter the layer height or surface roughness, bacteria managed to crawl in there all cozy like. The experiment was a succes, but NEVER EVER EVER use 3D-printed sex toys. Not even once (>>1868587) unless they're straight from the desinfection tank, and even then it's a retarded idea for toys that experience force (e.g. buttplugs) since one bad layer adhesion can mean there's 3D-printed stuff up your butt and you can't get it out. The only correct way it to 3D-print a mold and silicone it up.

I've printed a reprap printer, I'd recommend the hypercube https://www.thingiverse.com/thing:1752766 its a (slightly) cheaper/better option than the ender 5 since you can buy your own (far) better controller and hotend, but it costs around the same...
the BOM is in there, if its too expensive its easier to just get an ender 3 kit really...
I'd also recommend just buying a bondtech clone extruder, 3d printed ones are shit.
you can print the entire thing in PLA without issue (mine's lasted for 3 years without replacements, PLA bushings are wonderful once you print a nice fitting one and use silicone grease), but a heated bed should use petg.

I seem to get inconsistencies between every type of PLA I use, even when it's the same brand but a different colour. Is this always the case? More specifically; I had eSun PLA+ in green which was pretty cool but needed a bit more heat at the nozzle, then I bought some eSun PLA+ in red but I struggled to get it to print as nicely.

that's not the problem, you actually want that to be as cold as possible and the heat transition zone as small as possible, your problem is that your retraction is too long, so when a retraction happens it solidifies too quickly. Just lower your retraction.

Either you're getting unlucky with their quality control or there's other factors you're not considering. Were you printing non-stop and getting through a roll in a week or were you going slower and taking a month or more? Humidity over time ruins filament, so the longer it's out the worse it gets. Could have also been change in temperature, do you have an enclosed printer or live somewhere it's gotten significantly colder or warmer between rolls? Did you move your printer? Clean the nozzle? Maybe check and see if your model of printer has some "this eventually happens to every one" flaw like the Ender 3 and their PTFE-Hot End gap.

That's just how filament is. Different colorants do different things, and different manufacturers have different base formulas. hatchbox grey will print like hatchbox grey, but not hatchbox white, and no hatchbox filament will print like any esun filament.

You can get a Sinterit Lisa for like $9K. You might also be able to build a Binder Jet printer for under $1K, but given the question that you asked, I doubt it.

I went back to whatever slicer came with the a8, would there be any benefits to figuring out the newer version of cura? what features am I missing out on?

also, I've been printing exclusively in PLA since that's all I got before chinkflu happened. whenever I can get PLA+, will that directly work in my printer without any special bed, extruder etc? my anet a8 is completely stock.

pla+ would print fine, they just add shit to make it matte or stiffer, pla+ is a very simplistic name for a basic PLA hybrid
cura has some new features and stuff but you own an anet so until you can mod the thing to something more usable for detailed models you dont need to deal with reconfiguring your printer settings for newer versions of cura.

You're absolutely right. I keep pulling these out of my hotend after jams. I removed my enclosure (garage is still 95°F 35°C), printed a new fan shroud that focuses the cooler fan on the heatshrink instead of the old creality one but it is still happening. My board is 12v so I can't get a much better fan. Would increasing the diameter of the fan help? I read the creality one is ~8CFM. Is that BS? Could I stack fans to lower resistance? Stock fan is a 12v 40x40x10. Would a 4020 be better or a 5020 or 5010?

do you hear clicking? layer shifting is usually caused by missed steps in the X or Y, tightening belts should fix it. your longer prints look wider, so there's necessarily more movement in those axes. also, sorta dumb but, is your hotend affixed to the x-carriage properly?

OP of this issue topic here. Yeah, the creality one is not all metal. I got a replacement hotend. I'm wondering if the heat creep is from the metal tube connecting the heating element to the heat sync. I might try to nigger rig a dremel to act like a lathe and cut some grooves in it for heat dispersion before the heat sync.

How do I stop shit from sticking to the FEP? Every time a layer cures and it pulls the print up before lowering it again I can hear it being ripped off the FEP. If I lower my exposure times by a second it will get further into the print but my supports fail. I've even tried the WD-40 with PTFE. It made the FEP feel slick as hell but it still didn't work. My last 3 prints have failed because they keep getting ripped off the supports. I can't really rotate it either. It's a sphere but it's also hollow. There isn't some giant ass surface area that it's trying to pull.

Normally it shouldn't be a problem. 8CFM sounds way too high, especially for a 12V.
The meme answer is a noctua 4020. It's quiet, and though it doesn't have optimal CFM due to being quiet, plenty of people use it to great success. For 24v printers there are better solutions, but since yours is 12V it's probably fine. But again the main advantage is that it's quiet, I doubt it'll solve a cooling issue. If stock is failing to cool it adequately for you, then I dunno, maybe you might need to go big like a 5020, non-quiet fan, but it sounds weird and I haven't heard of other people having to do this.

To be honest, not much outside of exactly what the machine was and its characteristics relative to other things. I know that there is a market for custom figurines and the like (But I also know that 3D printing is not well-suited for mass-production), but I still get the suspicion that due to my ignorance I am not asking google the right questions. Still, I feel that I will get better answers from here than some website about some boomer telling you how you too can earn passive income with a 3D printer now! Click the link bellow if you wish to know more. So far a lot has being tabloid nonsense.

I do not want to sound entitled, and I am aware that this board in particular is tired of people with no knowledge asking basic questions, but there are so manny things I have to learn and I at least want some hints to aid in my research, since I have no prior interest in 3D printing I have no idea just how deep the rabbit hole goes and if it is even going to be worth it.

>option 2: learn digital sculpting (in blender or I hear zbrush is good for that) and print things
It can be a side hobby anyway, I don't see a reason to "switch to digital sculpting".
I mean, you can make thingies out of plastic. Being an SLA printer, the thingies can't be too big, but they have a high resolution available for potential detail. To make a thingy you have to create a 3D model of it (or find an existing one). That's the tools you have to work with, it's up to you to find what you can do with them.

I dunno, you could print tools or something? Jigs to hold up structures? Make "wireframes" or even mannequin-like featureless cores that you then detail manually with clay? I'm not a sculpter so I don't really know. For example, would a rigid plastic skeleton have any advantage over a metal wire skeleton that can bend?

This is my main concern, so far I always planned to do something like this:
https://www.youtube.com/watch?v=O0raRhCfrYY
Since a new opportunity literally just came by my door I wanted to know if I could use it in some way related to my hobby.
But even if right now I do not have a serious use for it maybe I should learn to sculpt digitally

Something I can think of right now are custom tools, and custom elements, I am much better at sculpting organic shapes, and struggle with unnatural objects like tools and the like. So if I make a character I would sculpt by hand his body and clothes, but 3D Print his accesories like swords and the like, at least so I can make casts later
Also, Maybe I could complement sculpting with 3D printed elements like making ball joints (where precision matters) so I can create posable figures. That's all I can think about right now

Oh Well, I first have to learn how to use the dam thing

Look closely, it has linear rods, not rails. Nothing wrong with V-slots on a 250 USD printer either. I'd sure prioritise a printer with linear rails on all three axis in that budget - but if it ain't broken, why bother fixing it?
>good cable management
Nothing wrong with the Ender 3 - and why would the i3 be better?
>and the monolithic sheetmetal frame is imho better than something you bolt together from extrusions.
Not better per se, it is far from monolithic since it can still bend and is still bolted together from different components. It sure is stiffer when done properly with thick sheet metal, but if I recall correctly the i3 only uses 0.75 or 1mm (or some imperial equivalent). Pic related used 2mm, and you could really stand on it during printing, but it also is way overkill in terms of amount of panels. A shop I've worked with has 20 Anycubic i3's for their print farm and they work well, but they took quite some time to get dialed in and I therefore did not recommend them in the original OP. Not saying they're a bad choice, I've just had more positive reviews from newbies with their Ender 3.

The smell varies a lot with the brand/type. The tough ones usually smell the most, while stuff like anycubic's plant-based resin is supposed to smell the least. It's not a bad smell, but it is toxic in any case, so you have to vent it outside. The more you breathe it in or touch it, the more sensitive you become, and it can get to a point where you can get a severe reaction from it. There was a pretty graphic pic of a dude on reddit who spilled some on their skin, they were likely allergic to epoxy.

Thanks. Nozzle clean, same location, same temps etc, no real humidity, using filament pretty quickly, couple of weeks for 1kg I would guess in general. The thing that piqued my interest is that the eSun labels have different recommended temp ranges on the two colours, so presumably something is different about them. I think one is like 195-215 and the other is something like 205-230
>>1869174
Thanks, I guess in general it's best to find a particular brand and colour that works for you and stick to that? I'm not bothered about what colour I use as anything bigger I would tend to paint.

>rails

Sorry my mistake, I meant rods. Still, akshual rods with bearings instead V slots.

It's a more shit resistant solution as any debris gets pushed along the rail rather than crushed under the rolling wheel.

The electrics are hidden inside the metal case on the i3 and protected while Ender has open PSU and other stuff on the open.

An i3 sat in a college 'workspace' (tiny bathroom sized hovel) next to a drill press and people creating flying shit through sawing etc.. I'd sometimes find it covered in metal shavings. Just wiped the buildplate clean with my hand and it worked.

>frame
Thickness being the source of rigidity is a misnomer. You need maximum amount of surface area as far from the geometric centre of profile as possible. The example in your pic isn't actually a very good solution. A flat plate is rigid only in one direction.

And aluminum extrusions are narrow rods, despite having more material. So the wide thin steel L profile on the i3 is akshually the better option.

>cables

Filament feed tube bends along a larger radius on the i3 hence less resitance and snapping brittle filaments like wood. Also cables in general are hidden neatly inside the frame so less chance for fuckups. Ender has open ribbon cables.

Ultrabase is nice. And setup is really quick - 8 screws, insert filament, level and print the owl.

tl;dr had one in uni workshop, has survived 2+ years of abuse and metal shaving showers by uncaring students. so i think it deserves a honorable mention at least.

I hope you're joking.

If you're not, there are several reasons you wouldn't use a level or this method. The bed needs to be square with the printer frame/nozzle, not the planet. Also, a standard level has nowhere near enough precision in terms of the tolerances that your printer works to.

Use paper or feeler gauges, paper is easiest and most accessible.

Your best bet is to use a resin printer to create a negative mold and then pour the silicon into the mold.
For metal make a positive mold, make a negative sand mold using the positive and then make metal mold from the sand. Won't be super good quality though.

>>1870853
With PLA, it's most likely a clogged nozzle in my experience. Printing other plastics, those signs indicate too much cooling plus poor layer adhesion. If it's early in the print, your bed may be too far and so the platic can't adhere well to other layers until it has self corrected a few layers in.

I'm a tard and have never done nozzle maintenance, so I guess I'll have to get on that and figure out how to properly check.
It did start early on but it continued fucking up the benchy print for about 1.5cm. Then it magically fixed itself and the rest of the print is great, although some of the bridging is garbage.
I added a BMG clone and also printed a bullseye, so the cooling and extrusion are different and the most probable culprits. I did think too much cooling could be possible (even if it sounds unlikely for PLA, plus I'm still only using the stock ender3 4010 blower), but turning off the fan yielded no difference, and the top half of the print went fine (with full fan).

Turn the nozzle on and try to manually push filament through, it may curl a bit at first, but with even a little bit of weight of extruded plastic hanging down off the nozzle as you push through, it should go straight out and down. If not and it keeps curling, proceed to try nozzle clearing stuff.

3D printing pisses me off so bad at times.
I had my shit printing perfect, like fucking awesome, but then something changed and I don't know what, it feels like a constant struggle to keep my print quality good. I leave prints running overnight and always wake up to spaghetti now. I was printing the hulk and the detail on the feet and lower legs was great (for FDM), but something fucked up around the waist and it spaghetti'd. The model was still stuck to the bed etc, so presume the nozzle caught on the print or the ambient room temp was too cold and it fucked up, god knows.

What do people tend to use for PLA in terms of retraction and stuff? I.e. speed, distance, and also z-hop distance etc. Pulling my hair out here and considering just trashing my profile and starting again, but it's infuriating as it could be a number of things causing the issues.

But I keep using the same motors from my old ultimaker original I bought on its release date. I haven't noticed any problems but that might just be because it's been a slow process.

I'm glad I got a 3d printer. Even for little parts like this filter it's super easy to jump into f360, and print something out with such accuracy, that everything just fits right into place. Final print was only ~0.07 mm off. Just blogging here, but damn we really are living in the fuggen future. Looking foward to making more practical prints.

Alright, PLA curling anon back here again. I tried the "passing some filament through the nozzle test" >>1870883 and it's giving me the exact same behaviour I've always had - filament curls up at first, sticks itself to the nozzle in a loop, then if I unstick it and let the loop hang down the weight pulls follow-up filament down as well. I might as well clean it to be sure, since I've never done it before.

I've gone ahead and compiled some photos of what the fuck is going on. At the top are a couple of shots I took while printing. In the middle are two shots of the complete benchy, where you can see the curling layer lines in places, and the absolute spaghetti at the front. It's worth pointing out that this shit was happening everywhere, including on the near-vertical sides, and then it stopped absolutely suddenly.

At the bottom are a couple of other attemps I made. I thought that since it'd started printing perfectly at one point, maybe it had dislodged a clog or something, but no, I am getting the exact same results, reproducibly. I also varied the speed, because I had tried to bump up my speed for that benchy - nope, going back to the normal slow stock speeds did nothing. Anyway, with the prints stopped really early on, you can very clearly see the layers curling upwards at the corners.

IFKR? I convinced the higher-ups at my company to get a Form 3 because I needed it for a few detailed parts that had too long of a lead time and were too expensive to prototype and they're constantly amazed by how fast they go from "I need this done" to "what do you mean you already have a final part?". Shit's great.

They kinda look mostly like my other prints. I did take those photos directly under a strong light, in order for the black plastic to actually have the layer details show up on camera.
It's sunlu PLA+ rated 190-220*C, and I printed these at 215*C (I've always printed around 215-220 even before this, with no real issues). However, I did flash a new version of Marlin (one of my changes was to switch from stock ender 3 to skr 1.4), is it possible the thermistor got "decalibrated" somehow? I grabbed PID settings from provided Ender 3 configs, but either way the temperature readings should at least be correct, right?

I'll try printing a temperature tower later today (provided I can get it printed without devolving into a spaghetti mess).

I have a bunch of parts that are long in one direction. 4"x 3" x 17" approx for the largest one, but the rest of them have similar aspect ratios. Because of the forces they'll encounter, printing them with the long axis in Z puts the layer lines in the weakest orientation. I need to print with the long dimension on X or Y. Most of the large dimension printers I can find have Z as the big axis, or are a fuckhueg 600x600x600 box that's complete overkill for what I want and have a $4000 price tag starting. Does anybody make a large xy, reasonable z printer?

>what is /3DPG/ working on?
A sub 100g filament drive based on an RC servo. Has been done before but this one uses a brushless metal gear servo to hopefully avoid motor failure.
Figured out decent-ish PID parametrs today. Next I'll move the electronics onto perfboard and mount it on my printer for testing.
Future plans include getting a new servo that does not have a bent output shaft, moving the software from arduino to C (possibly with a different MCU) and maybe getting a propper BLDC driver instead of tricking the servos controller into doing what I want.

Looking for a little bit of advice here lads.

A few weeks back I changed the nozzle on my Ender-5. After going through the rigmarole of changing it and re-levelling the bed to make sure it's all fine, I've not been able to get proper bed adhesion. At first I thought it was due to the nozzle change and re-levelled yet again. This changed nothing.

I've only been able to get adhesion on things printed with a raft and the last week the raft's have showed signs of warping in specific spots of the bed. I've so far been able to print around these spots but, it only helped a little bit.

Is there something I'm missing here?

>tldr: bad adhesion since nozzle change, can't figure out why

I picked up an ender 3 and I've been fiddling with it for a few weeks now. I'm learning to use thinkercad and doing various small adjustments and test prints. Tomorrow I'm looking at changing my nozzle down to a 0.2 for printing wargaming terrain and model parts. I've shifted my print speed down and I expect to get okay results but I'm curious what I could do to improve them further.

I want to print a town for a display board and add on parts for gunpla. I know they will need sanding and possibly filler spray on the flatter surfaces and I'm okay with that. Just fishing for any tips I wouldn't. Naturally run across.
