Based on what I saw in this thread PETG works better with the smooth sheets and PLA works better with PEI sheets. Since I have both types of filament. that seems like the right choice. Looking for some validation! All of the Prusa sheets are PEI-coated and only differ in surface finish. They have three kinds: smooth, powder-coated textured finish, and new satin-finish. The smooth ones work for pretty much everything and have the highest adhesion. The textured ones apply a neat texture to the bottom of your parts and have slightly lower adhesion. Satin is somewhere in between. The PLA/PET thing is because PET adheres extremely strongly to PEI. If you have a nice clean smooth sheet and you print a PET part that has a large surface area, it can stick to the bed so well that you'll damage it trying to separate them. The textured surface of the powder-coated bed helps decrease adhesion and makes PET more successful...but it's actually worse in other cases, like for regular PLA, where the adhesion of the normal bed is appropriate. However, you don't have to use the textured sheet for PET. You can use the smooth sheet and apply an "interface layer" to the surface, either a layer of glue stick or just wiping it down with Windex, which leaves a thin film of soap that reduces the adhesion just enough to prevent damage without letting the part break loose. Then for printing PLA, wash it off with soap so it's clean. Prusa has all of this listed on their website, e.g. https://help.prusa3d.com/en/article/petg_2059

The textured one is PEI applied directly and weirdly to the steel. PETG works best on the textured sheet. PLA works great on the smooth.

The Eyes Have It posted:PETG works best on the textured sheet. PLA works great on the smooth. Again, this is more complicated than X for A, Y for B. The textured sheet does not stick as well and that's good for PET because it's very sticky on PEI. It is 100% possible to print PET on the smooth sheet, you just have to be aware of the increased adhesion.

I will say that having a textured sheet for petg and a smooth sheet for pla has been real nice. No need to mess with anything extra is just convenient. Does suck when I swap sheets and forget to change the profile on the printer though.

Helped clarify things for me. I think this and the past few posts are enough for me to justify getting the 2nd sheet even if I don't use use one more than the other.

Ok HOLY poo poo this was weird just now. I received the silent mainboard for the Ender 3 today, flashed Marlin onto it and just started the first print on it. The fan was whirling like always on the PSU and I figured it won't be long until it starts printing. Then all of a sudden I catch a glimpse in the corner of my eye and notice the Z axis moving down from where I put it for servicing. The way this thing suddenly moves in ABSOLUTE SILENCE was almost scary, this is such a day and night difference. Like I was expecting a lot of the noise to be gone, but at least some mechanical noise or something. But nope, the fan now is the only thing making noise. I never was bothered by the operational sounds, but this thing still kinda blew my mind.

The Ender 3 v2 has silent stepper motor drivers and costs only $270. I built my whole print farm for ~the price of an assembled Prusa i3 MK3s+. I’m certain that a Prusa would have gotten me printing high quality prints out of the gate, but I’m able to pump out prints at a crazy speed with 5 machines. I have plants for expanding and even those would be the Ender 3 V2.

Aurium posted:You're welcome. The next thing would be resistance between fan- (that fan connector where you probed is fine) and DCV- on the power supply. This'll measure the fan mostfet. It should be open circuit. I had some stuff come up and disappeared for a few days but I was able to finally get in front of my printer again and pick up where we left off and when using the V- connection instead of the AC ground, I actually get the same results. I'm thinking maybe it's just something hosed with my Creality 8-bit silent board, and this might be an excuse to upgrade to the new 32-bit version. I'll reflash Marlin on it before that though to see if that changes anything. It really feels like a software issue after all this testing. To be relevant to the current discussion, aside from my cooling fan problem I've been discussing, my Ender 3 is near silent. I have a 40x20 12v Noctua fan on my hotend, and 40x10 Noctua 12v fan for the mainboard, and a 60mm Noctua fan with a printed cover on a Meanwell powersupply. You can't even tell the printer is on before my cooling fans turn on. First layer is dead silent. SpartanIvy fucked around with this message at 04:39 on Dec 11, 2020 |

I was wildly disillusioned with Creality quality back with the base Ender 3, but the v2 is just so goddamn nice right out of the box. Using this thing for a few months now and visions of having a little farm are dancing around in my head again.

So maybe this is a dumb question and the answer is to just use Fusion 360, but I'd like to do some geometric sketching with features like they are in Fusion 360's sketch mode, but I want to make some vector graphics from it. Is there some software that works about as intuitively as Fusion? Or can I just somehow get nice Vector Graphics from Fusion?

It does a pretty good job of auto-creating the vectors, too, if you have a good sharp definition of lines in the image you want to trace.

Doctor Zero posted:Are you thinking about any kind of management for the farm? Octoprint? None of them really offer them what I want. I’m also not very code savvy so I don’t really fancy the frustration of trying to get multiple raspberry pis set up and running properly. I’d need 2 as a minimum for my 5 printers, which ruins the whole ‘control printers from my phone’ in one interface idea. I have the same gcode on each of my printers, and most of my prints are in the ~12hr time frame. I remove the prints / start new prints in the morning and do the same thing at night. I check on how the machines are doing periodically through the day, as the print room is the next room over from the bathroom on my house.

Is there an effort post somewhere for resin printers? I am full of questions. I want to get into printing minis for role play and war gaming. I was looking at the Saturn, since it would let me print a vehicle or squad or adventuring party at once. But I also see the Mono X, E10, and Sonic Mighty in that space and I trying to figure out how to figure out which is best for me.

Class Warcraft posted:I broke the side off my filament spool while trying to fix a nasty tangle. Can I just like, put the filament in a bucket and run it from there, or will it continuously tangle itself that way? I think it could work, but I have concerns. There are filamentish things sold in bucket like containers. Twine immediately comes to mind, but I know I've seen others. It's probably not as simple as put pile into bucket. I'd want to feed it in so that it recoils in the bucket so as to make sure there aren't later coils on top of newer coils. I imagine a scenario where the feed is lifting a loop. I wouldn't really call it a tangle, but it could still get caught on something and kink or jam. Also pulling out of a coil introduces a twisting motion that unspooling doesn't. If you've ever coiled a garden or air hose you'll feel how it wants to twist to lay flat. I'd expect the filament to rotate in the extruder and this to not matter, but it is possible that it would build up tension until is causes an issue in the pile instead. Also, I'd expect it to be even more vulnerable to loosing the end.

There might have been some sort of file -> export option that's gone, but I never used it in the first place.
