Okay. I have a glass bed, I just haven’t installed it yet.

Are you sure the nozzle is close enough? It's hard to see with the blob in the way but it looks like you are still 1/2 mm or so above the bed.

It does look high. Also print speed should be fairly slow on the first layer. The fake buildtak stuff adheres great when it's new, so it's unlikely it's the surface.

I thought it was leveled right. It was low enough to drag slightly with a sheet of paper under it. I’ve printed a couple of things but it’s failing to stick every time now.

Lower it some more and try to get the first layer looking right Listerine posted:With the moarstruder, 1 wall is comparable, ~1.2 mm thick. But I didn't know if there was a structural reason why it would still be good to print at least 2 perimeters? The innermost perimeter overlaps with the infill, which can give it a bit of waviness that lines up with the internal structure of the part. If you want the smoothest outer surfaces, more perimeters are better. Structurally there's not going to be a massive difference in strength compared to the same wall thickness done with a smaller nozzle, no.

I've just spent 45 minutes fighting to upload that copy stand thing to Thingiverse (it is here). Where do the cool kids put their printables these days? gently caress Thingiverse in the gently caress hole.

How hot can I run my Ender 3 Pro bed without it demagnetizing? I'm getting a roll of PETG today to make some stuff for in my car, and the Amazon reviews for it say to use 75C.

Supposedly above 85 is where things demagnetize, but there are also lots of evidence of them being fine at 100c.

Dillon2 posted:Would STA printing drone propellors work or just make me look like a massive tool I think some companies sla print prototypes of new designs, but there's probably some compromises since the final pieces are injected molded pc. If you're prototyping new aerodynamic designs then it's probably a cool way to do it, if not...props are pretty cheap.

Dillon2 posted:Would STA printing drone propellors work or just make me look like a massive tool It would be the way to go if you were planning to prototype a new propeller design. SLA resin is nowhere near as durable as regular injection molded ABS or nylon, though, so the first time you crash, all the propellers are going to shatter. Not a good idea if you're planning to try and make your own propellers to save a buck.

Haven't posted in a while. Got an ELEGOO MARS about a month ago, and so far, really digging it. Downside is yea, resin printing is a bitch and complicated. Upside is you can get some crazy detail on tiny tiny prints.

While I'm thinking about it, is ABS the go-to plastic of choice for 3d printed stuff that will be left in cars during the summer? I've seen a couple of my PLA prints come out fine and a couple warp/shrink like crazy.

I've seen a couple of my PLA prints come out fine and a couple warp/shrink like crazy. It really depends on your climate. If you're in Tucson, PLA is probably not going to cut it. If you're in the Midwest or Pacific Northwest, it will probably do. Either way, I think ABS is the better material for the job.

Either way, I think ABS is the better material for the job. I can say from personal experience that PLA is not enough for a black car in an Ohio summer. Both of my PLA-printed car things that see sunlight are warped as gently caress. The one (pedal relocation bracket) that's always shaded is fine.

some PETG stuff has held up in- and outside my car for several Michigan summers now. it'll reach about 95f outside and hotter in the lot where I park my car for 8 hours, and obv hotter inside the car I printed a test-fit sunglasses clip in PLA last week and it was deformed within a couple hours

PLA+ in the car didn’t even make it through the spring in Phoenix without massive amounts of warping, let alone when it’s 115+ outside (but you can reshape it pretty easily when you first get in the car). I haven’t tried PETG yet, but ABS is probably the way to go.

Pure PLA glass transition temp is commonly stated as 140°F (60°C). Given the huge variability in PLA quality, the lack of purity, and additives for color could have an adverse affect on the transition temp. Wouldn't surprise me if there is some filament out there that will deform at 50C or less.. Edit: It looks like PETG transition temperature is commonly stated as 80C (176F), with ABS being 105C (221F) stevewm fucked around with this message at 20:24 on Aug 5, 2019 |

PETG definitely handles car-heat. I've got a tray/organizer sitting on the dashboard of my truck at work and it's survived the ridiculous summer we're having in Ohio without a problem.

If you heat treat your pla print it’ll probably last fine in the car

It's a blend of 7 herbs and spices. It's actually a proprietary blend. I don't know if anyone knows the exact composition, but it smells less, warps less, flexes more without layers separating. The only downside that I've run into is that it doesn't vapor polish.

It smells a *shitload* less. I think I did one print with regular ABS before deciding it was a pain in the rear end, but i'm two spools deep of ABS+ and it's way better. Still sort of wary of using it without an enclosure because degree of smell ≠ degree of danger but still.

My first printer, a ender 3 pro, just arrived. But while assembling a small metal clip fell of and I don't know where it came from. Any idea? Nvm, found it. Belonged to one of the end switches AlexanderCA fucked around with this message at 19:45 on Aug 7, 2019 |

That's the paddle part of one of the endstop switches. The sticky out-y bits hinge on top of the switch housing to push the switch down. edit: the foreground blurry one here is on the end of the x-axis, and the background one is on the bottom of the z-axis (I assume the pro has them in the same locations).  the y-axis one is in the back here across the center beam from the stepper motor:  Excuse the mess and the intermediate state of my ender 3 upgrades.

I just moved, disassembling my Anet A8 in the process. I've always had mixed feelings about it even after lots of calibration. I've been considering putting together the AM8 upgrade, but at best I can only find the extrusions/hardware for close to $100, and then I have to go through the hassle of setting the printer back together and getting it re-calibrated and working well to print out the parts in petg. Looking at what's on the market now price-wise compared to what I got almost 2 years ago I'm thinking about maybe dropping $300 on one of the newer printer kits that already has a metal frame. Any thoughts? Is putting in the work for the AM8 upgrade worth it at this point?
