w00tmonger posted:How do I go about getting cut 2020 and 3030 extrusions. I have no loving clue what I'm doing and the only stuff I can find is big lengths There's a bunch of vendors out there that will cut it to length. None that I have experience with. Search for "pre cut aluminum extrusion." ebay also has a variety of standard pre cut lengths as well, if the dimensions work for you. I'm also going to shrug at the tolerances. I know misumi will do it, from talking with people they were happy with he quality, and complained about the price. But skipping them, hack saw (or a portaband) and a file/sandpaper to clean it up. You don't get anything approaching square cuts unless you're in practice. If you have one, a chopsaw and a nice high tooth count wood working blade (cross cut, not ripcut) will work in a pinch. Go easy. More over there are also blades actually designed for cutting aluminum. They look basically the same as woodworking blades, but have geometry designed for aluminum. Decent saw = pretty square. Not metalworking square, but pretty square. Effort can get you very square. This is what I do, and design around. There are ones designed for steel studs and conduit, I'm honestly not sure they'd be better or worse for aluminum vs a crosscut blade over them, as the tool geometry for steel and aluminum tends to be pretty different. If you're buying a new blade though, which I assume you would be, you really should get the one for the material you're cutting. After that there's the usual metalworking solutions. Though they're basically all different saws and finishing options. If they were a serious option, you probably wouldn't be asking in the first place. Guess based on recent posting: if you're doing a voron there are a few kits out there.

If you show up to a machine shop with your extrusion and a crisp $50 bill about half an hour before closing time, you can make a lot of magic happen. This also applies to a lot of fabrication problems, actually But yeah it's aluminum, anything sharper than a bread knife will cut the stuff

Edit: Whoops, there is a laser thread after all, nm Edit 2: No, it appears to have been closed I'm looking to buy a Flux Beambox 40w laser cutter, but before I do, I'm trying to get a better sense of what it looks in actual operation in a real person's workshop. The problem I'm running into is that I can't find much in the way of reasonable photos and videos.. Anyone in here have a Beambox (not the Beamo, not the Pro, the middle one) that they could take some candid photos of? Snackmar fucked around with this message at 04:33 on Apr 5, 2021 |

Just put together a Prusa Mk3S+. Took me most of Saturday and Sunday minus frequent interruptions by the infant. I don’t have the heart to turn it on this late (early) and see that it doesn’t work, so I’m gonna leave the checkouts and troubleshooting and setup as a problem for tomorrow.

Stupid_Sexy_Flander posted:How does it print? Fast? Any aftermarket upgrades I need to worry about? I don't have one, but just so you know, the ender 5 isn't a corexy printer. It's a serial cartiesian bot, just not a bedslinger. The entire x axis rides on the y axis, like the old makerbots. It's not a bad layout, they can be slightly faster than bedslingers, though still not great as the y axis has to moves the x axis instead of the print. They're usually easier to enclose, but this one has a bunch of stuff outside the superstructure, not really in this case. The real disadvantage is that they have a larger footprint and structure (aka cost) relative to their build area than a bedslinger.

What motion system would be most suitable for a big printer with a large diameter nozzle and high-volume hotend? I feel like bedslingers need too much Y space with a big print area and CoreXY seems more suitable for small-diameter high-detail than a chungus nozzle

The amount of extra mass in a high-volume hotend is negligible in most cases. It's a couple extra grams of metal for the larger heater block, and the nozzle is actually lighter because the hole is bigger If you have a very large build area it's probably best to avoid machines that move the whole bed around. So CoreXY, H-bot or delta (or traditional cartesian with combined X and Y gantries) are good options. CoreXY is popular because the drive motors stay in one place on the machine's frame, reducing moving mass. There's no reason a CoreXY can't use a big chungus nozzle. Moving a large heavy bed precisely isn't an unsolvable problem, though. The vast majority of CNC mills move the part table in at least one axis. You just gotta pay for it

Yeah I just didn't know if you were doing something like pushing a Supervolcano (is that still the highest flowrate consumer hotend?) to its volumetric limits, would it be better to just go with something with shorter belts than a large CoreXY since your speed is so limited by flow rate anyway.

I'm totally new to 3D printing and recently bought an Ender 5 Pro, which I've been enjoying using. I live in a pretty small apartment which doesn't have particularly good ventilation and I've got the printer set up in my living area so I'm pretty close to it (~20ft) most of the time it's printing. I'm just using PLA for now - how worried do I need to be about breathing in harmful stuff, and what's the best way to counteract that?

Overall it took about an hour for me to assemble, and it has eaaily paid for itself just in weird microscope adapters I've been able to easily print (though I understand not everyone has a small business/hobby with tons of opportunities to save 40 bucks here and there if only you can make your own precise mechanical adapters).

Stupid_Sexy_Flander posted:How does it print? Fast? Any aftermarket upgrades I need to worry about? With the filament spool it takes up 24x24x28 (28 wide). It prints very well. Just as good as anything else other than my Prusa once you get it dialed in. It’s not as fast as my CR-6 but it’s still decent. Must have upgrades are the same yellow springs that the Ender 3 uses and a better build plate. The new ones might come with one, not sure. Mines 2 years old. The rest you can print, like a bed cable support and stuff like that. Optional upgrades, at least on mine, are quiet stepper motor motherboard, and relocating the filament spool to the top of the machine. Maybe a direct drive.

I'm not ballsy enough to strip the guts out entirely and build a custom chassis, but that's something I've seen on some of the boards. I didn't look too closely, but it looks like that's a LightBurn capable setup, which gives a lot of freedom over the m.2 setup I'm running. I'm still getting mine dialed in for the million different material options, and being an Amazon Vine member has really helped me keep experimental costs down.

Hadlock posted:What's everybody's calibration pattern? Links please I use something like this, just 15mm squares, 215mm apart on the X,Y. Heat up the bed and set the Z offset such that when this prints, the reference square (I use the one closest to 0,0) almost fills in properly. That is, you can still see the edges of the solid infill not fully making it into the perimeters. Then, adjust the mesh/screws until all the other squares print the same way. It is important to make the reference square not squished entirely, because you won't be able to tell if you've got it nailed or you're up to 0.1mm too close which gives too much error. Once all the square look not-quite-right like the reference square does, subtract 0.02-0.04mm to the Z-offset so now everything is perfect. I connect the squares with lines in the model so I can pull the whole calibration pattern up at once, but just arranging cubes in PrusaSlicer can get you there too with no modeling needed. In Klipper I just edit the mesh definition because my screws are close enough (<0.4mm) and they are under the glass so I don't want to touch them. I do my leveling at 75C, and I think ideally you'd have a different mesh for every temperature, but this works really really well and I only have different Z-offsets in the slicer profile for different materials. PETG is the standard, PLA needs to be 0.02mm closer, ABS needs to be 0.04mm further away. I have tried 832 different bed probes from servo arms with microswitches, to custom IR reflection triggers, to all sizes and shapes of inductive/capacitive probes and have never been happy with their results on my main printer. This works great, the prints start without doing all that slow mesh-checking stuff, and I just recalibrate every 6 months when I clean the build plate.

They have a pretty nice UI (esp compared to most laser solutions) but their biggest weakness is that the machine is totally dependent on a cloud service that processes your designs into gcode. Every unit will be a hunk of junk if that goes away (as happened with that one Printrbot model https://hackaday.com/2018/07/19/a-farewell-to-printrbot/), or you end up requiring a paid subscription to send your designs to the front of the line for "priority" processing (similar to what Cricut attmpted to do ahead of their IPO https://www.theverge.com/2021/3/15/22332212/cricut-crafting-machine-design-space-upload-limit)

Casnorf posted:These are good criticisms. yeah this is entirely fair, i don’t mean paint anything other than rapid prototyping and niche engineering applications as bad or worthy of criticism. i’m walking a fine perceptual line between my own environmental considerations and “judging other people for how they use their printers”, and probably should have been a little more specific wrt my thrust there, which was less criticizing use/application as “this manufacturing process is inherently wasteful in ways i have not experienced before, and it’s changing how I use and contextualize my resin printer”. i got into the hobby with a fairly specific Rapid Tooling production application in mind, but i also have a painted 40k 2000-point Imperial Guard ~Ineffective Themed Army~ in storage, back from before ‘phenomenal resin printers for $300’ were a twinkle in anyone’s eye... and i gotta say, i frequently marvel at how much more customization and love I could have poured into the hobby with today’s resources. I envy people who are passionate about hobbies for which cheap 3d printing is genuinely transformative. And it would have gotten me into CAD design a decade earlier in my life, which would have been helpful. Ultimately I’d like to see more people get into this, not fewer, because rarely can you purchase so much clean-cut *potential* for $249.99 off Amazon. I would, however, also like to see more conscientious and thoughtful use, and a general consideration of 3d printing that understands it as one tool in a toolbox vs The Extent Of Your World. Which, as you note, is conveniently also how you Fabricate Effectively, any potential environmental considerations are just icing on the cake.

I get what you’re saying but there are always going to be hobbyists in all hobby niches that buy a bunch of stuff at entry time, mess around, decide they don’t / can’t care enough, and ditch the material. It is wasteful sure but the fact is that it’s just the learning process at work. Plus, let’s be honest with ourselves about relativity here: I’d be willing to bet that the sum total of PLA and PETG and cured resin I’ve scrapped over five years as a result of support structures or failed prints isn’t even one tenth of one percent of the landfill stream that the company I work for produces every day. This isn’t to say we shouldn’t encourage thrift and thoughtful design to minimize waste - we totally should! - but also we should be realistic about the windmills choose to we tilt at. Gatekeeping about waste when someone is trying to decide whether to adopt 3D printing as a tool or hobby won’t drive adoption.

I agree with all of this, more or less, except for considering hoping people consider their environmental impact when it comes to their hobbies as "tilting at windmills". That goal isn't peculiar to 3D printing, it just happens to be more applicable than I've previously dealt with. And, yes, personal consumption is a rounding error alongside industry, just living a first-world lifestyle has a large enough impact that quibbling about hobbies is a rounding error of that rounding error, all granted... but "give this stuff a think, before you print" still stands, and seems like a pretty reasonable thing to gently hope for people to do generally, i think Ambrose Burnside fucked around with this message at 05:44 on Apr 6, 2021 |
