I'm doing something wrong; can't print this PETG

I have this PETG; its Kingroon Blue PETG. I can't get it to print nicely no matter what I do. Been testing with benchy over and over.

The filament is as dry as I can make it. It's been in the dryer for at least 12 hours before each print. I even have tried snipping the part of the filament not in the dryer to start from a dried state. The Relative Humidity doesn't drop anymore at this point (from 19ish).

I've tried different temperatures from 220 to 260. I've tried different retraction lengths and speeds. I've tried with the cooling fan on/off and at a couple middling percentages. Also different speeds from 30mm/s to 45 to 60.

I tried printing a retraction tower and it fell apart after the first level.

The first layer prints more/less fine, then eventually it either just falls apart (most of the time) or produces something in awful quality.

I've attached images of everything I can think of from the way it looks on the first layer, to the case where its a benchy out of a horror film, to when it just fails miserably.

Printer Elegoo Neptune 3 Plus. .4mm nozzle (i've tried both copper and hardened steel). Besides the nozzle its stock. If I swap to PLA it prints generally fine.

I feel like I'm missing something obvious. Everyone says dry the filament, but I can't dry it anymore 😢 .

Thanks folks (and if you celebrate: Happy Turkey Day!)

Intel RES2SV240 Firmware Update / Not always seeing drives?

Does anyone know where I can get the latest firmware for the intel res2sv240 raid expander card? Their website seems to just not have it anymore. (Sidebar: It is obnoxious that vendors take down support info and downloads after a certain point. Why is that even a thing?)

I'm not even really sure what the latest is at this point. Mine currently reports a

Storcli in efi shows:

product revision level = 0d00. ProdId = RES2SV240 VendorSpecific = x36-254.13.0.0

No idea what that stuff means. I just know that sometimes I boot and I can see the drives behind the expander, other times I can't. In other words I can always see my LSI Megaraid card (LSI MegaRAID SAS 9285CV-8e .. on latest firmware), but can't always see the drives.

It goes LSI Megaraid -> Intel SAS Expander -> Drives.

I'm guessing that the firmware on the expander might have an update to fix the behavior but who knows.

Any thoughts are appreciated. Thanks!

PETG weird edge issue

Hey folks,

I was printing a frame with a fresh unopened roll of PETG. I haven't seen this type of thing before. I'm guessing it's because I tried a new (to me) cura setting to move the seam to the corner.

Besides this area, everything came out great.

Any tips on how to get PETG and corner seams to not do this? (Or is the issue unrelated?)

My neighbor puts away his outdoor decorations every day

Every day at about 5pm he puts out holiday decorations (right now Halloween, but same idea for Christmas later in the year), then at about 9:30pm (~4.5 hours later) he brings them in the garage.

Every.. single.. day. Same schedule.

We're talking multiple lawn inflatables, led lights, and other misc decorations.

I've never seen anyone else do this before (especially every day).

Is this a normal thing for others?

Sidebar questions

Is there a way to always show the instance name after you swipe into the sidebar? I think now it doesn't always show the @instance.com part.

I guess one other sidebar thing: if I'm in the a community scrolling then I swipe to get the bar, it doesn't seem to come out. Is there a setting to make it so I can swipe to go back then swipe to get the sidebar?

Thanks folks!

I'll bite. Why is this PSU so cheap?

Link: https://www.walmart.com/ip/XPG-CYBERCORE-ATX-Modular-PSU-1000W-80-Plus-Platinum-26-Connectors-Intex-ATX-12V/724286138

.. why is this PSU so cheap? It's on at least one tier list as being A+ rated. It's 80+ Platinum. No idea if it has the latest connector for Nvidia, but I don't really personally need or care about that.

Sold and shipped by walmart.com, so should be a legit seller. Has a 10 year warranty. Returnable in store. What am I missing? lol

(I acknowledge there are some bad reviews.. but still sold and shipped by walmart. Maybe a bad batch?.. but come on that price still)

Why is this so cheap?

Is there a way to have a less depressing Lemmy experience?

It seems like no matter how I scroll I find bad news. I know lots of things are happening but I just want funny memes and interesting stories.

I used to be able to get this back in the day on the Reddit app feed, but here the all page is always just depressing stuff. Back then, there was news and stuff but like it felt more balanced in the all feed. I could get bad stuff but lots of interesting stuff too .

I find myself engaging less and less and just avoiding Lemmy more and more since I know the moment I open it I'll get whacked with more depressing stuffs.

I don't want politics or world news or really even memes about that stuff anymore. Heck even tech news is depressing. I just want simple scrolling of fun content. Idk it's just hard to describe.

Does anyone else feel this way about their Lemmy experience?

I remember an old post about someone getting AM radio from their sink (probably from Reddit back in the day). That type of stuff is so much cooler than my feed.

To that end: any recommended active communities on Lemmy with that type of stuff?

Weird PETG Printing Behavior

Hey folks,

I'm not sure what I'm doing wrong. I'm printing PETG (https://kingroon.com/collections/petg-filament?) on my Neptune 3 Plus. It's sort of like it starts (almost) ok, sticks to the plate just fine, then a few layers up it seems to almost have inconsistent extrusion (or maybe even trouble pulling the filament?) leading to holes, etc. till the model just falls apart. See linked photos for about where I give up each time.

I'm printing with Cura and 240C printing, 90C on the build plate. 45mm/s (I've gone down from 60mm/s). Retraction on, no z-hop. 60% fan, though I've tried it with 20% and 100% fan as well.

The filament is in a dryer at 55C. Funny enough I printed basically perfectly (without drying, straight out of the bag) with default settings the first time I printed. The second time and on, have had this problem... and have had it in the dryer.

Any ideas would be much appreciated. Thanks!

Edit: In case its useful, I'm printing this piece: https://file.io/D9jxYq4KOrL7 which is a small remix of a piece from https://www.printables.com/model/130507-bolt-action-pen-for-pilot-g2-cartridges

Why does the US government subsidize the building of EV chargers?

At one point I thought that if the Government was giving money for EV chargers, they would be either at-cost or free to use.

One of the first built was at a Flying J truck stop in Ohio.

I looked on plug share and found one in Hubbard, OH and it's 67c per kwh (https://www.plugshare.com/location/582660). The average cost of electricity in that area is less than 15c per kwh. At that kind of price, gas could be a cheaper option.

Why does the government subsidize in a way where already wealthy companies get public money to build chargers, and make a ton more money off the rest of us?

(This is not a political statement at all. I just don't understand why public money goes to make certain private folks more wealthy. I figure I must be missing something).

Thanks for your thoughts!

How to get wood sealant off of a window

So I was using a wood sealer (https://www.amazon.com/dp/B01AQTX3XU) on my newly built catio. Unfortunately I didn't notice how much I had sprayed on the adjacent window.

Now I have cloudy/foggy windows (https://imgur.com/a/TKD9wim). I've tried cleaning them with:- - - -

  • water via the hose directly on the window.. very little progress
  • windex.. very little progress
  • dish soap followed by host.. very little progress
  • vinegar.. very little progress

Any ideas for what might get this stuff off easily?---
