Not higher print head speeds (those sometimes have to be toned down) but massive nozzle sizes and layer heights are what give you that huge volume flow. 15mm nozzles aren't unheard of.

it's good enough for welding a continuous line as long as nothing changes
but as soon as you reach the endpoint (tu delft) or have too much heat in it (tony building up high)
the quality goes to shit you would have to constantly adjust your welding parameters
there are two ways to do that both need a lot of R&D
either your slicer can precisely calculate what parameter is best for which part of your print beforehand
or you have some kind of feedback loop adjusting amperage and feedrate continuously based on some sensor

either way is much more work than just slapping a welder on a printer setting it to x Amps and y feedrate and just going for it

It already exists. There are several brands. Some use wire-feed with a laser as the heat source for the melt pool, some or just basic wire-feed MIG
https://www.youtube.com/watch?v=MdEit7aPRh0
, and some are fancy-ass powder spray with a path for a laser or electron beam, through the middle of the nozzle as it sprays powder.
https://www.youtube.com/watch?v=G4m8eRmGWFI
https://www.youtube.com/watch?v=oL7bMhPTtDI
And a marginal few more use extremely high velocity powder spray (sometimes heated) to just deposit the material. Those are called cold spray or plasma spray guns.
https://www.youtube.com/watch?v=UUd8VM2d2pY

The wire-feed machines have the worst resolution of the bunch, so they're mostly just used to make a near-net-shape billet in alloys that would would have cost more in tooling to produce using only machining.

No you don't, you can buy more expensive components from reputable sources outside of China. Most of the bad reputation of Chinese clones is from cheaping out on parts, bad design, bad assembly or bad firmware (thermal runaway). You can avoid all of these by buying the proper parts, with a good design for your printer, assembling it carefully and putting a stable firmware on there. If you do this with chinkshit parts, just accept that some will be duds and buy replacements - cheaper than buying Euro or US stuff anyways.

If Bosch are better, how come they don't offer black anodized versions? Item also now has both 5mm and 6mm channel widths for their 20x20 extrusions so you can use any type of T-nuts you want.

At the time i was looking at steppers from Lam Technologies (Italy), and while they offer a tiny bit more torque on their NEMA17 models, a single motor costs about as much as 5 chinese Wantai or Motech ones so i passed.

Yeah, I've noticed that too. If I buy something from a German, he sets the price after the quality. If I say "I can pay you 10% less", he says no deal. With the Chinese, chances are they say okay and then sell me a 10% worse product instead. As long as you find a decent seller and don't buy the absolutely cheapest version they offer I haven't had any quality issues. It's when you go on ebay and sort by cheapest+shipping that the problems start.

Case in point, my buildtak ripoffs aren't the cheapest I could get, but they work just as good as the real deal. When I went to the local makerstore and bought their buildtak it was pure shit, probably because what they'd done is just buy 200 of the cheapest thing aliexpress had listed.

That depends greatly on what board you already have. The easiest method i can think of for a cheap 8bit Atmega type board would be to buy another one and a raspberry pi, then use the Klipper firmware. The Pi controls both microcontrollers giving you in total more stepper drivers and extruder heaters than you need.

Sounds more like lost steps, so motor current can be too low, but it also can be caused through a bed that is wobbling too much during its movement. Hard to tell without additional information. How tall was the print? How much space did it take on the build plate?

It's not actually another 150, I picked up my ender 5 for $250 on 11.11, will probably be the same on Black Friday.

And IMO yes, unless you are on a hard budget I don't think the Ender 3 is worth getting anymore now that the Ender 5 exists, it's a printer you can eventually print any material with including PC, ABS, and Nylon. The kinematic system is way better than the i3 style.

What's your first layer height?
I print .2 first layers always, regardless of if I'm doing thinner layers after, because it makes it much easier to get adhesion and it compensates for the warping your bed gets when it heats. I don't even have to use paper now, I just push the nozzle to each corner, eyeball it, and it works fine.
If you're willing to spend some money, BLTouch is pretty easy to install and set up, with it you only need to level the bed once. Some people with it just tune their bed once and then put hot glue on the adjustment screws so the bed will stay tuned.

Something you can do for free and that also makes things easier is installing the latest marlin 2.0 software. With it you can click your display wheel twice to get a "micro stepping" menu, which lets you fine adjust the nozzle height. You can use it to tune the printer as it goes. Just slice your print to have a wider brim or skirt, and then adjust the nozzle while the printer moves. You can do this with the tuning wheels too if you want, just be careful you don't burn yourself.

Can't say that for the Geeetechs. Personally, I know six people with an Ender 3, none of them have had any significant issues, and they're happy with them - can't say the same for the Geeetech.

Yep, solved it. (despite having tried that multiple times before)
The problem was the clips on the plate being misaligned along with the z-stop aligment.
Fixed the clips and and got the z-stop to auto home exactly right for the higher edge meant I could now only just trammel the plate correctly.
Probably also partly due to the springs being shit.
First print seems to adhere perfectly onto the glassbed and everything is looking good.

Could have saved myself about 6 hours of pain but now it's finally printing no problem.

Well, sort of. Most extruders consist of a little gear that mounts directly onto the shaft of the stepper. You can't really make the gear smaller, which means the only way to get good torque is by fitting a bigger motor. The option is something like a BMG, which is a gearbox that downshifts the stepper to get good torque.
But getting enough torque is a real problem, especially on bowden setups where you need to maintain a higher nozzle pressure. Try heating your printer up and pushing filament through by hand, you need to use a bit of force.

Yeah right now I'm installing the hero me dual fan duct and a micro Swiss clone as well as a quieter 4010 fan. Still waiting for my SKR E3 to come in the mail.

I haven't pushed it yet, I'm gonna try for 100mm/s+ once I get the new board and set up Klipper. The roller system is really rigid and I don't have any worries about running it that fast. I'm going direct drive as well, but putting a smaller stepper motor and a geared BMG clone on instead. I think people overplay how much weight affects the print head. Stepper motors with nice TMC drivers are super strong and should be able to fling the print head around with ease.

>> No.1725444

Weight tends to be an issue when you get past a certain impulse acceleration iirc. The reason why linear advance was implemented was because people started turning that down to go up in speed but slower jerks caused the corners and curves to blob/overextrude. It's also why stuff like carbon fiber gantries, bed plates, and why h-bot and coreXY got more attention from DIYers who wanted to achieve industrial grade speeds.

300 cubed+ sized printers that aren't bed flingers are probably going to run $500-800 DIY or not. Do you need a large build volume?

>>1725444
Yeah but a pancake stepper and a mostly plastic BMG extruder don't add enough weight to really become a problem for the steppers. I think the gains in things like sharp corners or part accuracy from direct drive are worth using it for. Also makes tuning new materials easier.

As I remember linear advance was implemented to compensate for each individual printer's distance from the extruder to the nozzle and is primarily used to compensate for the filament slack in a Bowden application. You need a much lower linear advance value for direct drive. It's still useful but not as much as for Bowden setups.

I know what you mean. I went to the Voron site to look at the bill of materials, and it was this ridiculously long list containing brand-specific and expensive linear rails, which meant I couldn't even save some money by buying Chinese clone parts. I honestly think it might be easier to just design your own coreXY at this point, just buying whatever profiles and rails your hardware store carries and designing your printer around those. The actual machine isn't actually that complex, it's mostly a matter of getting everything squared and tight, which is easy if you already have a decent printer since you can just print custom tools and fittings for everything. Angle brackets and other fittings for aluminium profiles are all over thingiverse, so you might not even need to CAD anything. Even that "Voron parts must be printed from ABS" seems a bit excessive, since PLA+ is a more rigid plastic nowadays. If you're not putting it in an enclosure, it shouldn't matter. I suspect the Voron guys might be gatekeeping to keep Enderfags out.

They're hiwin mgn9hs. There are a fair amount of clones out there, but they should have used MGN12H. The 12mm rails are by fair more common in terms of clones and have been used by plenty of people so they have good sources for cheaper chinese ones.

You can try the (new?) Sainsmart Coreception. It's 300x300x330mm, but I have no idea how good it is. CoreXY is simple but a lot of chinese still can't get it right, the moving belts need to be parallel so the distances don't change as the carriage moves around. Fortunately the Coreception looks like it has completely parallel belts which is a good sign, but can't speak for the quality of the components. For that size you could have a look at the hypercube evolution which should be perfectly fine up to 300mm. Or you can look at the sk-go which is around $800 shipped from taiwan

Thoughts on making a "table cnc" style very large printer?
I'm thinking of something like 1000x300x100 print area.
Replace the linear rails in pic related with aluminum extrusions and bolt everything onto a 5mm thick steel plate, this steel plate also works as the print surface.
It wouldn't have an exceptional acceleration due to it being huge and there being quite a lot of weight swinging around but throw a volcano hotend on there and the print speed ought to be pretty ok.
And as for bed leveling i'm thinking of using some sensor, mechanical or induction, on the hotend and then doing surface mapping to account for surface imperfections of the print surface.
I'm not quite sure as of yet which axis ought to be the long one, currently i'm thinking of making the axis in pic related that goes from right to left but i'm not quite sure.

Not very often, true - but then again, most people rarely printer larger than 100mm cubed. The problem is that people rarely consider redesigning an object into parts so it'll fit into multiple printers at once, which massively increases your production speed and reduces your failure rate. Most people should consider buying a printer for 80% of their printing needs (in terms of print volume), and outsourcing or slicing up the rest.

Yea the SK is probably a good one. Chinese kits can be hit or miss. It will be open for order today I believe, but there's a big facebook group waiting for it to come out so you'll want to keep an eye on it if you want one. Like I said, one man project, so he probably won't have a ton of units to sell per batch. He sent out times earlier this week but I think I deleted the email. There is one concern that I've seen some people raise with other corexys, and it's that the corexy pulley mechanisms are just screwed down at the bottom and not braced at the top. Apparently it's possible to tighten the belts enough to pull a nut out of place or bend a screw over time, although I don't know if that's a particular problem with the sk-go, just a concern floated around when custom coreyx printer designs started coming out. The popular diy designs like the hypercube put the pulley bolt through a top and bottom so it's supported at both ends evenly.

Took the weekend to figure out the basics of Fusion360 and made myself a 75% mechanical keyboard, at least a raw test print of it. I'm quite happy how this came out, now I gotta fix a few little things and print it with a higher density. It's only 20% infill with 2 walls printed with a 0,6mm nozzle and 0,48 layer height. I wanted to make a quick print to check it out but I really like the big sausage layers you get at 0,48 and I'll probably stick to that with a higher infill.
It looked real flimsy during printing because of the big gaps but ended up being quite sturdy.

I just bought the tevo tornado for $200 off AliExpress with free shipping, and it's amazing. Prints 30 minutes after opening the box, everything straight.

When you are the only one that got a gay printer. Feels bad.

First printed the cube on the left with a custom designed extruder, had some severe underextrusion, axes weren't calibrated, some other minor problems. Mostly ghosting resulting from that inconsistent extruder.
Calibrated the axes properly, and installed a Bondtech QR. Set E-steps to their recommended value (not sure if that's a good idea without calibrating E-steps, but hey), and printed the cube on the right. Ghosting due to the extruder is gone, but with the X-Y bed it's still got some scruffy looking corners - so I'm going to do some acceleration tuning next. what's the deal with the top surface though? The ''outlines'' are perfect, but the middle square is extremely rough. Overextrusion with the nozzle dragging through it? Anybody got an idea here?

Looks like over-extrusion. Go ahead and calibrate the e steps as a starting point, at least.

You should buy your Creality shit from the offical store imo. Like 90% of the people whining about the quality of their Ender's beyond the usual issues of shit springs/warped beds etc are running some shit clone that has shit XT60s.
They also have the option to ship from Belgium so you don't get fucked by taxes.

Even the official models had this though, not just the cheap copies.

>Ender 3 Pro (for the meanwell PSU)
A meanwell LRS-350-24 is like 30 bucks so it really depends on how cheap you're getting it compared to a regular Ender 3.
Ender 5 is probably worth the upgrade though.

Yes but Creality actually fixed theirs on the newer models from what I can tell.
