EchoCranium@lemmy.zipto 3DPrinting@lemmy.world•I want to branch out from PLA. Should I try ABS or TPU?English2·4 months agoIf you have an enclosure, I would say try out ASA. Similar to ABS, I’ve found it makes some really nice parts that are tough and UV resistant. Great for things you want to leave outdoors. Otherwise TPU is useful stuff too, and no heated chamber required. I was using it this weekend to print up seals and grommets for a trailer I’m rewiring. It’s nice being able to print up some parts I need rather than making a drive to the hardware store and hoping they’ll have something I can use.
EchoCranium@lemmy.zipto 3DPrinting@lemmy.world•(Troubleshooting) Advice for improvementEnglish3·4 months agoI agree that it’s probably a speed issue. When I first started printing, I was seeing just how fast I could go with PLA and tuning for that. Decided to try out PETG a few months later, and it was a disaster. Layers weren’t bonding properly, and the filament would bridge across points on the print. Once I backed print speed down to 50, I started to get much better results.
EchoCranium@lemmy.zipto 3DPrinting@lemmy.world•i just got a 5m trial piece of tri color filament.English4·6 months agoIs it the color shifting filament, or coextruded type? I’ve used coextruded red-yellow-blue that looks really great when the prints were done. The three blend as they melt, so you get a rainbow effect of red, orange, yellow, green, blue and purple that shifts as you turn the finished piece. Anyway, for a short length of filament like you have, try doing a standard test print like a benchy or any small figure. Even if you end up short of filament to finish, you’ll have an idea of how the filament will look if you end up buying a roll.

You programmed a turtle cursor to move around the screen and create drawings. That was definitely a long time ago.
EchoCranium@lemmy.zipto Technology@lemmy.world•Raspberry Pi 500 and Raspberry Pi Monitor are available nowEnglish30·7 months agoThey neglected to include a M2 slot for a SSD. If they add it to a future release, I’ll have to get one. Could finally have my own Shadowrun rigger deck!
EchoCranium@lemmy.zipto 3DPrinting@lemmy.world•Do I *need* to learn a 3D modeling software?English2·8 months agoI find that being able to sketch up things I need in CAD and then print them is both cool and really useful. It’s the main reason I bought a printer in the first place. Thus far I’ve tried out FreeCAD, Solid Edge, and Blender. With any modeling package, you will have to dedicate time on a regular basis to really get used to them. FreeCAD is certainly nice for the fact it’s free, just as it implies. I used it to design a few parts that were functional. It works, has some useful workbenches and add-ons. My problems were the software having bugs that caused models to break when trying to make changes, and available training info was often outdated. Siemens offers a free version of Solid Edge to makers, which is really nice, even with some of the advanced features turned off. It’s a much more polished program with great training resources. You can only export designs as stl files, but that’s fine for 3d printing. Solid Edge will slice and print, but I always import files into Orca and go from there. Blender looks really amazing for modeling, but I admit I haven’t spent enough time learning it yet. You can use it to manipulate meshes, which is useful for customizing and fixing models. I’ve used it to Frankenstein together different models for custom prints I wanted. But yeah, while you don’t have to learn to use modeling software to do prints, it opens up so many options for you to be creative. I think it’s worth while.

People were traveling out of country for joint replacements. Costs were less for travel, surgery, and recovery than what they would pay for it here. Covid put a damper on travel for a couple years, so not sure if it’s still as popular. I would consider it if/when I need knee replacements done. Considering what I’ve heard about the quality issues of joint replacements in the US, I don’t want one here.

You’re right, it’s dangerous and certainly has a lot of risks. With some background in it myself and access to resources that the general public doesn’t have, I would still be hesitant to try something I’d cooked up in the basement at home. But, I’m also not at the point where I’m going to die from a treatable but unaffordable disease.

I test the API’s that process chemists make to be sure they’re right. Yeah, reactions don’t always proceed as intended. These guys do understand the risks, and are only trying to provide an option. Here in the US the insurance companies are perfectly willing to let us die because funding expensive treatment hurts their bottom line. Unless you’re independently wealthy, a small scale reactor at home may become the only option a person has available. Definitely risky, but why not take the chance when corporate America has determined you’re not valuable enough to save?
EchoCranium@lemmy.zipto Technology@lemmy.world•Your TV set has become a digital billboard. And it’s only getting worse.English2·11 months agoScepter televisions are a great option, no “smart” features at all. Bought two of them about 6 years ago and no issues.
I’m going to make the assumption that is PETG you are working with. I had cobwebs like that when I tried moving over from doing PLA. There were a few things I had to work out to get better prints.
- Slow down the print speed and work up once you get acceptable prints. Try 40 to 50mm/s to start.
- Increase filament retraction. Default I think is like 0.2mm, try 1.0mm instead.
- Increase the travel speed. I’ve used 350mm/s, which helps break strings, as someone else already suggested.
- Drop the extruder temperature. PETG gets more stringy as it gets hotter. Lower temp may help, and if you aren’t trying to print at warp speed, bonding should still be good. Do small test prints to see where your cutoff is. Also, if the cooling fan on that Sovol is a bit anemic then printing cooler lets each layer solidify before the next one gets added. Hopefully you get things worked out, good luck.

EchoCranium@lemmy.zipto linuxmemes@lemmy.world•Do you install linux on old laptops?English3·1 year agoNot a laptop, but I had an old motherboard from over 20 years ago not doing anything. Screwed it to a board on the wall of my shop. Added an old hard drive and some components out of the same old box it was in, and now have it running Mint. Found an old wifi card that works too, so I can look up parts and repair videos while I’m working on projects. Works great.

Could easily burn through 12 hours like that. Just need to be able to take a case of Jolt, a few bags of chips, and some Skittles along and I’d be set.

It’s a dual drive redundant setup. Unless something catastrophic happens, I doubt both drives will go out at the same time. I could do an offsite backup as well, but just haven’t.
Put in for a replacement power pack on Friday. Just had to enter the order number from Amazon, and upload two pictures of the power pack including the model and serial number. Bought the recalled one in 2018, and it was still working fine when I charged and used it last month. Oh well, I’ll drop it off for recycle next trip to the county waste facility.
