My Ender 3Dv2's hot end is clogged. Shameful, I know. Yet I feel I'm among friends here. I started shopping for a replacement, because I have more money than time, and I found that Creality is selling a direct drive extruder for $30, or a replacement hotend for $15. Why might I want to just replace the hotend and not move to a direct drive? What about this $100 direct drive option? Or another brand? What should I do, thread? Halloween is coming up, so I have to move fast!

One of the challenges with direct drive conversion is greater mass in the print head, which means more vibration/acceleration compensation required. But if you plan on printing finicky or flexible filaments, then DD can be very helpful.

Rexxed posted:Uncle Jessy has a video looking at his Prusa XL. Not a full review but a look at it after a few days of use. He does a lot of cosplay helmets so he's got a few large format printers. So, the same print was slower and worse quality on the XL compared to the MK4?!?. I know, it's a pre-release, but still. And no input shaping on the XL?

Not sure if this is the right thread, but does anyone know of any good UK-based print services I can throw a file at and say "I need 16 of these little things?" I need some Ikea Blaliden shelf brackets printed but I know nothing about 3D printing.

Here4DaGangBang posted:Haha, really? Seems a bit cheeky for a brand name when Polyalchemy is a brand of premium filament.. 😮 Well, it's the same as the store name, and I don't think I've ever seen Polyalchemy filament here in Norway, so I imagine it's perfectly fine. They also have a different one, PolySmart, but I don't buy those because those come on cardboard spools, and I can't be bothered to deal with that for the AMS. (Also I really like the all-translucent spools the Polyalkemi ones come on.) I'm really tempted to ask them if they'd consider selling refills, honestly. Surely it can't be that big of an ask when they're custom ordering dozens of types of filaments? e: Also, speaking of software optimizations to stuff like filament waste: https://www.printables.com/model/582382-bambulab-profile-for-up-to-60-purge-reduction Someone's rolled out a Bambulab profile that claims to reduce purged filament by ~60%. It does so by retracting the filament 2cm before cutting and swapping, meaning every single filament change has ~50mm3 less filament that needs to be purged per swap. I imagine this increases the risk of clogs, but I'm really curious to see how well it works in practice. I imagine it doesn't do this by default because there's a risk of pulling up melted plastic into the cool zone. SubNat fucked around with this message at 11:06 on Sep 18, 2023 |

I think barring any more stupidity from UPS I may be able to use my p1s today at some point. Why no you can't redirect your delivery to a UPS store because it's an option on the we missed you sticker and you even talked to the driver via your doorbell. No you can't change your delivery because we haven't attempted delivery yet (umm I know I'm not going to be home). Change it on ups my choice... it doesn't even show there. Sure you can collect it same day from the dist center 10 miles away - phone agent. Lol no way, we close at 5 and trucks stay out much later than that - ups dist center lady.

Apparently the guy who wrote/maintains SS recently quit his job and will be developing SS full time starting in a month or two, so hopefully it can start playing catch up with Prusa/Bambu. I love using SS with my Voron but I want tree supports

Prusa Mini is getting input shaping. I’m so glad my little war horse is getting a big speed upgrade. Firmware is still in alpha. https://github.com/prusa3d/Prusa-Firmware-Buddy/releases/tag/v5.1.0-alpha1

That's fine, Josef. I didn't want input shaping on my XL anyway. But seriously, updates like that are one of the reasons why I'm totally comfortable with the XL being in the state it's in (which is to say, a good printer but maybe not worth the price of entry and the wait time at this juncture). Not happy about it, but not losing any sleep either.

I have considered getting the MK3.5 upgrade kit, Josef, but it's been out of stock on your website every god drat time I look. Ah well, got a Creality K1 instead because the bad decision train ain't stopping anytime soon.

Does anyone have any advice on printing gears specifically? I want to mess around with designing some mechanical stuff, and I'm wondering if there's special consideration around the size of teeth or layers or things like that. More specifically I'm thinking of designing a 3d printed turntable with a simple 3V motor and some gear reductions.

I want to mess around with designing some mechanical stuff, and I'm wondering if there's special consideration around the size of teeth or layers or things like that. Pay careful attention to layer line orientation of anything that is going to be under strain. Prints are stronger along the axis where filament is laid down than they are along the axis where one line of filament is bonded to the next. This can throw a pretty good wrinkle in to the design process as you are no longer only considering things like over hangs and such during the slicing process. There may end up being directly opposed considerations in this process that require significant trade offs.

Almost every single involute gear profile generator is trash. Genuinely the only good one I’ve found out of the box is an Onshape custom feature, and it’s still approximate (but good enough). Also instead of doing math, just download STEP files of the gears you need from McMaster to use for your print.

https://github.com/Audiotronix/Positron_LT The Positron seems to be an abandoned project. Some community members have developed a mostly 3d printed, lighter weight, easier to build version that still does everything the positron did. It's still early going, but it's better than other.. more mature projects.

Anyone have any recommendations on uninterruptible power supplies? I'm about to embark on series of day-long prints, and I'm not about to waste that much time/filament if I can help it.

Zorro KingOfEngland posted:Anyone have any recommendations on uninterruptible power supplies? If you think you'll have short power interruptions they're worthwhile. If you think you might have a power outage that will last a while you'll want a generator or one of those large power stations. Most UPSes for computers exist to handle short interruptions and will run their estimated maximum load for about five minutes. This is so you can back up your data and shut down safely more than keeping the computer going. That said, using less power will let the UPS run longer, but in that case you want the biggest one you can get. I've got my 3d printers on some of my old small UPSes, a couple of 685 VA Cyperpowers (with AVR) and the large format on a 1000VA. I believe the 1000VA is rated for 600 Watts max load and the smaller ones are in the 350 Watt range. They work fine for the Monoprice Maker select, Ender 3, and Sunlu S8. One time I tried to run two printers off the same UPS and when both beds were heating it overloaded and turned off, though. Depending on what you expect to run into for outages, power interrupt resume is useful on the printer itself, but beyond that a medium to large UPS isn't a bad idea if your area has bad power. It may not save you for a large outage, however. I've got a bunch of cyberpower units and a few APC ones.

Yeah, I'm more worried about short blips than I am about long outages. If the power goes out for longer than 10 minutes I wasn't gonna be able to save the print anyway.

For my voron, I split the bed from the rest of the electronics and put use the same UPS but on either side (bed gets the surge protection but no battery, the electronics and hotend get the battery). I use a 1500VA battery.

Yeah I almost got the K1 Max but frankly the increased power draw would be a problem especially with my home's generally not great circuitry. I have the MK3S, the K1, and a filament dryer all on the same circuit. Any more and I think I'm gonna trip it, not that all three are running full power at the same time often. I do have a Kill-a-watt so I could measure at least and see...

Ok I replaced a wonky heater wire on my hotend on the voron, and I can complete a pid tune. Now I sat down with a fresh super slicer and tried to start making .6 nozzle profiles with . 3 layer height Using the pla+ I use all the time that is perfectly consistent and new out of the box, running 220, all my stuff is melty. Going down to 190 but now I'm dragging parts off the bed. I have a tap but I'm printing way too low. I feel I need to basically reset my printer. Cfg and start over. Nothing is working as it should
