One option is 3D printing a mold to fill with silicone sealant. If this is a part that fails regularly, the mold may be worth it. You then have a pretty broad array of food safe sealants you could use and don't have to worry about your 3d printed part harboring bacteria.

Oh, I am right there with you. I don't want to write tests because they're tedious, so I backfill with the AI at least starting me off on it. It's a lot easier for me to fix something (even if it turns into a complete rewrite) than to start from a blank file.

I've used them for unit tests and it still makes some really weird decisions sometimes. Like building an array of json objects that it feeds into one super long test with a bunch of switch conditions. When I saw that one I scratched my head for a little bit.

Same. There's something really cool here and even if I'm not a chess guy, it's still worth it.

Depends on the webapp, traffic, etc. I have an EC2 instance and my own domain that runs me a solid $7 a month. It's just a tiny little web server. If your web app is structured in a way that the client does the processing, your hosting costs can be pretty cheap.

For instance, rather than editing a PDF on a server, if your web app provides all of the tools to edit the PDF in the client's browser, the server doesn't need to be particularly robust. Basically it just needs to hand out those tools to the client.

Hoo boy I had it going way too fast. I had it moving at 150mm/s. I very strongly suspect this is about 90% of my problem. Layer quality already seems vastly improved a few layers in at 50mm/s. I very much appreciate the insight!

I haven't run PLA on this printer. This is actually my second one, I modded my first one to the point of unusability. Maybe starting back with PLA is a good idea.

I'll try dropping temps and see what I get. Thank you!

[โ€“] franzfurdinand@lemmy.world 1 points 2 months ago

I haven't had issues with curling but the enclosure is pretty new. The room is pretty variable with temps. The windows are old and maybe a little leaky.

Word. I'll give that a go, thank you.

 

My prints up to this point have been okay, but not great. Serious stringing seems to be an issue here, and one of the things I've notice is that the further along the print goes, the more it seems like the print head is almost grinding into the print. To the point where if I'm printing something like a minifigure, it will get ripped apart mid print. Am I overextruding? Missing z steps?

Filament is Overture PETG, Nozzle is 230C and bed is 80C. I have it in an enclosure. I'm running it from a laptop set up with Cura.

They're sequential, so the values above and below yours are valid SSNs of people born in the same hospital around the same time.

This would make it trivially easy to get access to records you shouldn't

Honestly that could be kinda soothing in a way. A nice little slice of life with low stakes.

 

Hey y'all, I managed to hack together a printer from scratch and I'm struggling to get it to print well. It's a CoreXY system that's being controlled by a Octopus 1.1. Dual z screws, the works.

I have it moving under it's own power and all. It's able to actually print, but the results are atrocious.

I'm just trying to diagnose what's wrong here.

The bottom/first layer actually looks kinda good. It's just completely shredding subsequent layers.

Any advice would be appreciated!

 

Howdy y'all, much like the title says, I'm looking to build a Hypercube. I have what was once upon a time an Ender 3 V1 that I've rebuilt with an Ender Extender kit. I'm not happy with the aggressive ghosting I get from the 400x400 bed so I wanted to cannibalize the electronics and build the frame from scratch. I was also planning on keeping the bed since it's got a stick on heater and thermistor that'll work well with the new setup. Hotend too, probably, since it's an all metal Micro Swiss.

Any gotchas to look out for? I know belt tension is a biggie once I get it together, but any gotchas to look out for in the build process?

I'm not too nervous about throwing together a custom firmware for this, it's not my first custom firmware and I'm a software guy by trade so it's pretty straightforward for me.

 

I've been putting these things together for a few years now and I wanna show them off a little bit. I originally started making them to solve a problem - I'm kinda tall, and I like having a blanket that can cover me up from my head to my feet. I hadn't found any that could do that, so I started making these 6'x12' blankets. The example here is fleece on top and flannel on the bottom!

The heart is my maker's mark. Orange because leggy.
