>I don't need <thing> for anything, convince me to buy <thing>!
There's a smple answer: don't. If you need a 3D printer, you'll know and buy one. It's extremely unlikely that you'll end up in a situation where you urgently need something printed, can't wait a week for a printer to get delivered, and can't get anyone else to print it for you.
I don't understand this mentality where people actively WANT to buy useless stuff, knowing it will be useless to them. Same thing with the raspberry pi. For what fucking purpose would you buy one if you have no purpose for it?

If you have a bunch of free money and time, you could buy a printer just to mess around. 3D print figurines and miniatures, or random trinkets. But since you're asking, you clearly don't have enough completely disposable income to just impulse buy like that, so don't.

Nvm I looked up the difference. From what it seems the biggest functional difference between 3 and 5 is the increased Z capacity, which increases overall build volume. There are other differences like the box structure and the axis movement that will increase print quality. In my opinion the 3 is the better option because you should be able to compensate for the quality differences through things like print speed (at the cost of print time). Consider that you could put the extra Ender 5 money into dial-in resin or half of a second 3 Pro

Is a homemade printer likely to give better results than something like an ender 3, without spending more effort on tweaking than could have been spent tweaking an ender 3 to the same level? Assume I have a good budget to get quality parts, and that just assembly and initial setup time is free (building stuff is fun, repeatedly making tiny adjustments to fix minute defects in a highly repetitive and tedious iterative process isn't).

The context is that I have an ender, and building my own printer might be a really fun project - unless getting things "just right" after finishing the build is expected to take a lot of tedious effort, in which case realistically I don't want to bother.

I went the route of DIY and made dolly prusa mk2 which Tom did for something like 200-250eur, with alu frame. It worked fine on ramps/a4988 but I did have problems with clogs with mk2 extruder and had problems when I upgraded to tmc2130 from fystech.
Then I bought the bear upgrade kit, genuine e3d hotend and printed mk3s parts for bear and it works flawlessly now (with skr 1.3 and tmc2209). It depends what is your goal, do you just want to print or do you want to explore, build and maybe spend more money in the end, because getting a cheap printer will lead to spending more money.
In start when I had problems with fystech 2130 I was so mad I bought a prusa mk3s cause I needed to print parts for my projects without thinking. After a year of having both prusa and dolly I decided to upgrade the dolly since the skr boards became widely available and there are a lot of guys actively working with those boards/hardware (Chris Warkocki one of them for example and Chris Riley) making calibration and tweaks easy (you can literally copy paste marling from them and it just works with standard calibration).
To shorten it up, everything requires tweaking to get perfect prints, but a homemade or prusa will get better results then ender, it just depends how much time and money you want to invent into them.
Since you already have an ender you are in a pickle, just like i was cause upgrading from dolly would cost more money in the end then going from the beginning, that of course being valid if I sold the dolly.
My advice would be to upgrade ender to most popular upgrades like bltouch, dual z axis and just end it there, and go for new printer either diy or market one, you have to sort do you want fire and forget printer or are you confident you can build a rigid machine that will fulfill your needs. Honestly, after building a bear prusa clone I can honestly say it's rigid as hell and building it was pure joy.

This makes sense. I think it'd be a fun project then at some point in the future.
I'm probably not gonna bother heavily modding the ender though, it's working just fine as is right now so if I start spending money and effort on stuff it'll probably be for a completely new DIY one then.

Time to use some of curas magical settings:

Use "outer wall wipe distance"
This feature lets the nozzle do a wipe without extruding before leaving a wall. Reduces stringing.
More info
https://youtube.com/watch?v=_QRb54zVPfQ

Use "coasting"
This feature stops the extrusion shortly before the travel of a line ends. Reduces stringing. Start at 0.2

>improvements of 5 over 3
>What are the differences?
The whole frame and moving axis concept (core xy) is a lot more rigid.
BUT this comes at the cost of complexity (more belts etc.) and it still uses v-slot roller axis. It is also if a fucking huge machine for it's build volume.
Improvements seem to me more academic than practically relevant when looking at reviews. I'd personally go for the 3. The i3 MK3 is propably a better machine than the Ender 5.

I don't think you can get anything worthwhile from ender in electronics/hardware, I went with LDO motors for z axis since I couldn't find any viable z axis leadscrew solution in EU at the time I was buying parts, other motors are common nema motors which are fine by reprap standards and run cool and precise with tmc2209. I usually go for the chinese route and buy cloned parts, but do some research before if there are problems like for example the fystech problem I had, or if you decide to go for prusa cloned bed, there is a problem with magnets, I suggest you join prusa bear group and other i3/prusa groups where people build their own and you'll get good information and builds.
I'm just attaching the picture of my dolly bear, you can see it has mk2 bed and ender sticker, that's cause of Corona I failed to get the prusa genuine bed in time.

For the first time in years, I'm having an issue I don't know how to solve and don't know what is causing it. I'm trying to print a small model at .1mm layer height and every damn time I've tried, it starts failing to extrude at almost the same place. If it was the same layer, I'd suspect the GCode. What happens is I get loss of extrusion (with the exception of two of these, which detached from the bed, THEN got loss of extrusion). The filament extrudes fine by hand, but whenever it "jams" I can no longer push it through by hand and pulling it out of the extruder is very difficult - the tip is also bulged, but it's smooth. The damndest thing is I was getting consistent prints with Bronzefill a few days ago, and now I can't even print simple PLA.

Temps are 190-215 / 60. Picture is a little bit over-lit but I can take another one if it would help. What's going on?

0.4mm, stock MK3S + MMU2S extruder. I've had problems with the extruder stepper overheating but that was only on extended MMU prints out of ABS since the thing would spin the entire time filament was loading - I've been printing great up until about a few days ago, but this is the first time in a long while that I've used 0.1mm layer height so I can't help but think that contributes somehow.

If you do it right, yes

>without spending more effort on tweaking than could have been spent tweaking an ender 3
Nah, the effort and money to get a homebrew printer to the level of an Ender 3 ist quite remarkable.
If you want to go beyond the Ender 3, the effort would be pretty high. The only reason to get into this would be for the fun of the project itself.
To pull this off you would need a lot of experience in 3D printing first to be able to tell what error is caused by what issue

>>1791334
>getting a cheap printer will lead to spending more money.
I disagree.

>upgrade ender to most popular upgrades like bltouch
not neccessary at all, once you got the experience to adjust it by eye during the printbor skirt in the beginning. I use different bed heights for different materials to get perfect adheison.

>dual z axis
Might be a good idea. But again, the effort required is highly questionable. Just adjust your v-rollers as good as you can, it'll be fine with single z.

My two cents on this:
The stock Ender 3 can get pretty good prints out of the box. This is enough for 98% of what people do with 3D prints.
If you want to sqeeze the last perfect bit out of FDM you need to go crazy effort. Do a fuckton of testprints and adjustments. Just not worth it imho. I have never done a testprint.

95% of problems people have with their prints come from a) wrong printer assembly b) funny slicer settings they found online outside the filaments recommendations c) filament issues d) using anything else than buildtak as a beginner e) funny mods that are actually a downgrade

Pic related is my first 3D print ever on a stock ender 3. It came out almost perfect and quality is like this ever since. It takes some time to get every screw right on the ender but thats all you need. Same applies for my stock CR-10

>getting a cheap printer will lead to spending more money.
>I disagree.
Anon above asked if it was viable to upgrade ender to something better if that is possible and what's the best route. I know people who are also happy with their enders and anets and get similar results and never thought on getting any other functionalities. Keep in mind that a lot has changed in the last 2 to 3 years in 3d printing tech like trinamic drivers, skr1.3, buildtak surfaces and so on. If you were to upgrade ender to have any of those functionalities it will cost money and probably more then just buying parts for a completely new printer. I have no idea how anet and ender handle abrasive, flex or high temp filament but as far as I've seen it's not possible to print without modifications and heavily tinkering, correct me if I'm wrong.
So to shorten it up, if you were to add features to ender it would cost money.
I'm not saying they are 100% needed, as I said before most people don't even know about them or need them, but I personally wanted to remove endstops and have functionalities of tmc drivers and auto bed leveling to reduce interaction with the printer.

the skr e3 is literally 20$ with 4 2209 included
The ender PEI build surface is good. if you want something different, ann FR2 plate thats indefinitely better and does not smelt on nozzle impact is 10$
for flex you'l likely need a modified extruder, thats a few print parts (but this depends on shore hardness of the filament)
The Hotend is plenty fine for ABS but you might need to trim the tube every 50hours and a beginner will have a bad time with all metal anyway

>or high temp filament
I've went through kilos of 260°C PETG on the all stock bowden and hotend. No issues at all.

The secret for flex is to get fucking slow. I mean 15mm/s.
TPU needs more longer time to liquefy in the hotend compared to other filaments.
You also need to crank up the flow/extrusion rate to ~120% because the extruder teeth grip a lot deeper and the feeding gear diameter is reduced. Otherwise you will underextrude. I'm also coasting at 0.4mm3.
As soon as I considered these points I got very good results.
I'm printing TPU with retraction turned off, I should give it a try though. Stringing is quite hefty.

Posting in a new thread, might get new answers:

Can someone help me identify this filament? I have no idea what it could be, nor how old it even is. It's a little bit bronze/metallic in appearance, reasonably flexible (but it's probably not intended to be, it's a little crumbly if I do it a lot), very soft, and not electrically conductive. It feels like it's about the same density as ABS/PLA, and the spool is much smaller than usual. There's not a single label on it so I have absolutely no info to go off of. I haven't tried burning it yet because there's an infinitesimal chance it's either ABS or PLA due to how it feels and I don't know enough about the results to judge them.

Those are the same spools that Filaments.ca uses and they have a line of flexible PLAs (PLA/TPU blend) so it could be that. Probably another brand coming off the same factory line. Does it have a matte and sort of rough finish?

If it is, it's an absolutely amazing material to print with. Firm yet pliable but not gummy like TPU.

That's a better guess than flexible PLA now that you mention it. I missed the part about it being crumbly.
The reason I suspect it might not be from them is because they have a spool indicator sticker on their spools, but you might have a sample spool or something that neglects it.

They have really good selections and their house brand is pretty good, much better than the average chinese filament. They also have ziplocs and desiccant included with each spool. I'm a canuck so I order from them exclusively because of price and shipping. They also recently launched a line of PLAs using Ingeo Resins so you won't have to splurge for $40 spools from Ultimaker. Would definitely recommend their flexible PLA though. It's fun stuff.

Not that helpful for 3D printing.

PLA isn't even listed. PET and ABS are in the same endcategory. The many additives for 3D printing such as glycol for PET can change the smell and burning behaviour drastically. Mechanical additives in exotic filaments (metal flakes, wood dust etc) change the floating behaviour in water.
Better suited initial tests such as snapping and bending behaviour of the filament aren't shown here.

There are none, and any ways of mitigating the symptoms are just going to be shitty hackjobs that probably will end up costing as much or more as just replacing the faulty parts.

If it's the screw, you might be able to carefully bend it straight enough to bring it under control. Fixing the coupler would require a lathe, though.

Ignore >>1792149, he's a fucktard and it very likely is either the screw or coupler. Those are the only things that can even cause that type of defect.

Look real close at the Z axis motion components when jogging that axis. You may be able to see some slightly motion that would help out. If it's wobbling near the coupler, but not near the top of the screw, the coupler is the likely culprit. If the other way around, the screw.

Just looking at the part, it appears that the ridges become less pronounced the further away you get form the bottom. That's usually an indicator that the coupler is the problem.

Not necessary if you want a good print. The community should stop giving advice to upgrade, upgrade, upgrade.
If you get a cheapskate print, and it works, leave it be. If you run into headaches that remodeling or slicing won't fix, only then should you start buying or printing upgrades. The best way and cheapest way to silence your printer is putting it in another room, for example - why bother spending money on it before you even have your printer, and why risk cocking something up that wasn't broken in the first place?
>If it ain't broken don't fix it

Hi anons, I have a problem and I can't figure out what's going on.

I try to make my old Mendel prusa to work.
I changed the mother board, so I have a brand new Bigtreetech SKR V1.3 with the last Marlin flashed, running at 12V with enough current.
Right now, I unplugged everything except the LCD (Reprap discount 128*64). (so no extruder, no heat bed, no sensor except relevant axis endstop)

So, I try to make the axis works.
When I plug the X motor and X controller, no problem, it moves fine without noise or hiccups.
When I plug the Y driver, the movement is very rattlely and too short and depending of the driver, may whistle.
As soon as I unplug the second driver, everything goes back to normal.
I tried different configurations of axis and (correct current configured) drivers (official Pololu md09c "black" A4988, chineese probably-a-knock-off A4988 and seems-ledgit DRV8825), same problem everytime.

To sum up, whatever the number of motor plugged, one driver is fine, but more leads to trouble.

Hey, I'm having issues with flexiprints. When I print one out, it ends up being fused together. I have already tried reducing flow, adjusting esteps, adjusting layer heights/line width, etc, and am not so sure on what I should try next. I'm printing on an ender 3 pro with .4mm nozzle at .12mm with PLA. The last print i did, I tried it at 75% flow and 166 mm/s esteps, usually my printer runs 196 mm/s for its esteps.

Layer height is: .2mm
Initial layer height is.12mm

Z-banding anon from yesterday. I noticed last night that both lead screws have some wiggle room at the top of the frame, apparently designed to not make the screws bend to the frame. On the right screw it sits in the centre and has wiggle room, but on the left screw it is pushed towards the front of the printer, and can't wiggle around on its own. Rolled the lead screws on a table and the seemed ok. Putting it back together I noticed when re-inserting the lead screw into the couplers the right screw fell in more or less easy, bu the right screw kept falling onto the edge, and the coupler/motor just didn't seemed line up, but I don't know how I can fix this. It doesn't seem like the motor can go forward any further. Would it be the coupler in this case?

Random question as someone with virtually no knowledge of 3D printing: Is there a way to print hard plastic pieces?

How do you go about switching the polarity of a motor on an ender 3 without touching the firmware? I've done it on my prusa by just flipping the connectors. However with the ender I've seen some say that you only switch pins 1 and 4, doing otherwise would brick your machine. Is that correct?

Uhm no. "Rubbery ones" are made of a thermoplastic elastomer, normal TPU in most cases.
Exotic filaments are filaments with other mechanical stuff blended into them such as wood dust or tiny metal flakes for certain effects. Chemical effects such as glow in the dark, silk or color changing when heated are also sometimes considered to be exotic

Your z-screw can be as lose as it wants. It's the v-roller excentric nuts that define your axis slack. Your frame allingment defines if the slack is consistent over the range of the z-axis.
I have to say the design on the X1 is extraordinarily whacky desu. You might want to print a tighter guide for the nut.
For testing, you can print the identical g-code multiple times to see if the banding is random or on repeatable areas. The latter would indicate that a local spot on your rollers or axis is fucked.

Not all i3-style printer use two Z-axis steppers. In my opinion, using just one side is stupid and may cause the unpowered side to trail behind the power one due to any slop in the construction. If you have two steppers power two leadscrews, and you level them individually using two endstops, all the slop is taking out of the system, just like with a really sloppy lathe you're always creeping up on your tolerances from one end, taking up the slack.
>Could I couple two parallel steppers on both sides of a leadscrew to increase the overall torque?
Yes, but why? It would still result in one trailing end, and depending on the pitch of your lead screw a single stepper already delivers enough torque to make those small Z-steps even when loaded with 25kg of weight last time I calculated.

Uhm yes. Most people don't bother with Ninjaflex or TPU, hence why I said "exotic". It's not a word with a specific category of filaments that it does or doesn't apply to.

Instead of two light steppers on a single Z-axis, you're better off with the same two light steppers on both Z-axes instead. Best yet would be to ditch the Nema 17's I presume you're using, and go up a size or two - and then still use two motors to power the two axes.

Sometimes, when doing a large flat surface (like a floor), each line of filament will have a length during which some kind of ridge pops up. It manifests on successive lines in continuous areas on the 2D surface being printed, with no obvious pattern, and depends also on the direction the surface's lines are being printed. The result over an area looks like a small elevated plateau noticeably higher than the layer height, composed of "spines" of sorts coming from each line.
Sorry for the shitty blurry pic, but hopefully it puts my verbal explanation in some context. You can see two of these raised/spined areas near the foreground, and you can make out how the material twists up into a thin ridge at the edge of the walls. This is the second layer of the print - I don't think I've seen it happen directly on the first layer, but I have seen it everywhere else.

What could be the cause of this, and what kind of fix could help?

Okay so I noticed while turning Z that the couplers weren't straight on the steppers and were causing the rods to get pushed around. I removed the couplers and, while holding a U shaped print between the motor and the coupler and pushing down on the coupler, mounted them back straight. I also inserted the rods in all the way until they rested on the small rubber ring that sits between the rod and the motor shaft inside the coupler. I think this ring is here to prevent the coupler from getting compressed when the extruder is on one side of the X-gantry, while still allowed sideways movement of the Z-rod. Reassembling the entire thing and turning the Z again, I was virtually no sideways movement at the top of the rods. Right now I'm printing the same print I printed last night that was suffering from terrible Z-banding. Let's hope this piece of Chinese shit doesn't disappoint me.

>> No.1792991

>>1792978
movement in the z rod does not matter at all as long as your z nut can move freely on the horizontal plane
Whats more crucial is the z rod being parallel to the frame. on the ender this comes from the retard motor mount that requires either shims or a print part that lets it sit flat on the extrusion

i dont know why you keep going on about the z rod or the nut when issues with this axis are either warped frame, shot rollers or the motor not being 90° to the frame
two out of those issues you check without the lead screw installed, moving the axis by hand
the other you measure with whatever you have

>> No.1792998

>>1792958
Not that I know of. A motor on each corner would be statically indeterminate, you should use three for this idea, but on any system with a moving bed it would add a lot of inertia to said bed. You'd need more than just motors or servos, probalby small lead screws as well, etc. etc., it'd be a mess for very little gain when you already have that option of movement in the regular Z-axis of the machine.

Take your time putting it together - make sure all your angles are square, bolts are snug, and belts are tight. You will get great prints without adding shit. If you're gonna print parts for your printer anyway, I recommend a PSU support bracket to get weight off that vertical rail, a filament guide, and a fan cover.

Don't worry: you're not building a 3D-printer, you are heavily modifying one. It is very much something to be proud of once you're done, but it's not Mount Everest. Calm your tits, parts seem solid, look up every step on Youtube, and get to it. Just carefully think about the answers to the questions above, they might get you a bit farther.

Is the whole point of this to learn? If this is about flexibles surely there's an easier path in modding your i3 mega to use direct drive. Depending on what flexible your print with you may even be able to do it with your bowden like >>1791437 suggests.

FIY soldering is easy and you can buy practice boards from chinkland for $2-3 to get your first joints going, then once you have taken the first steps and figured out how the process works, you can get your real components connected with confidence.
There's obviously a big difference between an experienced veteran and a newbie, but with proper 63-37 leaded soldier, some good flux if doing SMD, and a couple of youtube videos or even just photos showing how much soldier you need (and how to spot bad joints, insufficient soldier, or too much soldier), it's quite hard to get a truly shitty joint. It may not be the most beautiful but it'll still be functional.

These are legit questions, thank you for addressing them!

>Why an i3 Zero when you're familiar with the Mega?
My needs exceed my i3 Mega.
After lurking for 8 years and discovering custom attachments (e.g. a concrete extruder, spindles, dremel adapters, etc) I saw that all of them had extruded aluminium frames not rods. When I first saw that I immediately knew I needed one not only because of its rigidity but also because of its expandability. Also, I intend to attach a linear rail to (and if I buy) the Zero.

I wanted a feature-packed machine with an extruded aluminium frame so bad I almost went for a Creality CR-10S Pro V2.
But Covid times are hard and I don't have the cash to blow.

>Why not just buy another Mega for parts commonality and experience (especially if you are in unknown territory)?
Because this would be a learning experience for me. I want to familiarize myself with electronics through something that actually matters to me.

>Why exactly those drivers?
Futureproofing.
I intend to eventually upgrade the stepper motors to be able to carry a lot of weight (i.e. a concrete extruder).

>Why go for a bowden system if you want to print flexibles?
I will replace that as well.
Once this COVID chaos settles down I'll buy an E3D Hemera.. or Flexion (but that red's fugly).

>Why not do the ''project'' one step at a time, instead of doing it all at once?
Because I have a couple friends who are incredibly talented (I live in a town with a lot of ind. designer students) and would gladly sell them my current i3 Mega to help them out, thereby also easing on the costs of the new printer.

I may sound like I have my mind made up, but what I know is my needs exceed my current printer and the modifications (fortifying the frame, etc) would be too much $ and effort in the end.

Well not when it's used as a meme to answer stupid questions, but it's legitimate advice. It's just useless to anyone who doesn't care about linux as a hobby or otherwise have time to dedicate to figure it out, which is why it's meme advice.
"Buy a prusa" is, first of all, specific to this thread and not /diy/ as a whole, and second of all, it's actually the opposite kind of advice - anyone can buy a prusa and get good results (unlike with gentoo where you have to be dedicated), but there's often (if not always) a much better and cheaper alternative (unlike gentoo, which most often would be an actually good solution, except in some specific cases such as someone wanting to host a production server or something).

How does an all-plastic gun sound? Now you can get pretty resillient plastics but they can be expensive and/or hard to print. Not something you buy your first 3D printer for and get going with to just make one gun.
There's also designing it. I have no idea if there are any properly functional gun designs out there, so if you can't find one ready made you're gonna have to fire up a cad program and create yourself a gun.

Now, what you can build are air-powered guns (there are plenty of modded nerf gun designs, and probably ones for denser kind of ammo), bows/crossbows, that kind of stuff. You'll still need some non-printed parts of course (such as air cylinders for nerf guns, or limbs from a proper material for crossbows).

You can lost-PLA cast a receiver blank (brass or aluminium would work), but the tolerances on casting are so poor you will not achieve a lot of the required final sizes required for a receiver to work, nevermind threads. You would know this, if you knew how to build a gun without a 3D-printer.

So after replacing all the washers on my z nuts so they can actually move around and shitty spring washers that creality installed aren't blocking the movement the nuts can now move around, but made 0 difference.
