Yeah same here. Tje decorative stuff can be cool but I also tend to stick with functional stuff. That project your working on sounds pretty cool, I'm looking forward to seeing how it comes out. Electroplating prints is something I've been interested in for a while but haven't tried it yet.

Oh wow thanks. I did lightly sand the top surface, that's about it.

Overture glow ABS. It Prints well for me. To be fair, I took these pictures right after walking inside from the sun, so it was nice and charged up.

 

The plastic loop on my old viper remote broke, so I popped it open to get some dimensions and got to work in fusion 360. This is rev2 printed in glow ABS.

In the order of acquisition:

  • Ender 3 (Converted to an Ender Extender 400xl). Dragon hotend and EZR struder.
  • Ender 3 Pro with dragon hotend, EZR struder (currently being fitted with a Sherpa Mini DD). Running Klipper.
  • Ender 5 with Biqu H2 v2s Revo (recently got all the parts to convert this one to a Zero G Mercury one.1).
  • Sovol sv04 (With Copperhead heatbteaks).
  • Ender 2 Pro with E3D Revo Hotend and MicroSwiss Bowden extruder. Running Klipper.
  • Voron V2.4r2 350mm.

Currently all are operational except the Ender 3 pro, due to the Biqu H2 v1 blowing up on me last weekend and forcing an upfra to the dragon+Sherpa_mini+HeroMe toolhead.

What I am about to say will probably go against what at least a few people on here will say, but I've been printing PETg (and PLA, ABS, tpu, etc...) for about 5 years now on 6 different machines. It all started where you are now, on a stock (besides a microswiss hotend) ender 3 and a glass bed.

For me PETg Prints as easily as PLA every time by following these guidelines.

  • 1. This is the number one most important thing when printing PETg. MAKE SURE IT'S DRY. PETg is very hygroscopic, which means it absorbs moisture from the air like crazy. It's a requirement (IMO) to get a filament dryer, or food dehydrator to dry your PETg. I dry it at 120°F for 6-12 hours in a modified flld dehydrator. Even when stored in a vacuum bag with desiccant PETg will still not stay 100% dry. Wer filament will bubble and make it weak, make it stringy as a guitar, and lead to weak parts.
  • 2. Invest in a PEI coated spring steal build surface. Smooth and textured both work awesome. It just depeton what surface finish you want. Personally, I would start with one that is powder coated with a textured finish, as it's more forgiving to uneven beds and also releases super easy once it cools off, usually the part will self release so you can just grab it right off.
  • 3. Don't use any type of adhesives on the PEI. We use PEI on our high dollar, over engineerd Voron printers for a reason. When you heat it up to the proper temp, prints stick to it like theres no tomorrow, As long as you keep it clean! I don't even bother with isopropyl alcohol anymore, use blue dawn and a paper towel in the kitchen sink. Dish soap is a surfactant, which means it washes contaminates away, instead of just moving them around like a solvent does (isopropyl). From talking to people online about it, some of those adhesives can actually cause adhesion issues.

Temp: I print PETg at 245° first layer and 240° after that. I run 75° on all of my beds with PEI sheets and have great adhesion.

Part Cooling: PETg doesn't tolerate part cooling as well as PLA. I run my 5015 setups at about 30% fan speed which delivers a good balance of print quality and strength.

It should also be noted that you should really invest in an all metal hotend when printing above above 230°C. The PTFE tubing in the stock lined creality hotendt begins to break down above this temp and puts off some really bad chemicals, like chemicals that are said to eat holes in your brain amd stuff... Also, you will have less headaches with an all metal hotend, just be sure to lower your retraction accordingly.

Well, this has turned into a wall of text so I'm going to stop here. If anything I said doesn't make sense justlet me know and I'll be happy to clarify. Cheers.

My friend, you have nothing to worry about. Try 6 printers and over 150 spools...

Glad it's not just me. I can't even log in on liftoff anymore for some reason, just sits there loading forever. Tried clearing cache and data and reinstalling to no avail.

I've settled on liftoff until boost is released. Seems to be the best combination of functioning features and nice UI IMO.

This list looks about right to me

I built an LDO Voron v2.4 kit and it's amazing. It Prints multiple times faster than any other Printer I own at noticably better quality. It wasn't cheap, and took a while to finish. But it was worth it.

 

We recently adopted a 9 week old kitten. We took her to the vet who confirmed she is dewormed, and that she is due for more shots 4 weeks from the date of her last shots.

We also have a 7 y/o cat who is up to date on shots as of a few weeks ago.

We have the kitten staying in her own spare bathroom for the time being, but we would like to start the slow introduction process as soon as safely possible.

Would we be putting the older cat at any risk if we were to **not wait until getting the kitten the rest of her shots?

Hoping there's something vet professionals here who could offer some advice. Cheers!

 

I recently bought a thinkpad T470 for a good deal, and it turns out that it was a good deal because the BIOS is locked with an admin password so I can't install an OS, or change any BIOS settings.

I also recently came across a paper that describes a "security flaw" in most thinkpads where you can bypass, then reset the admin password by shorting the SDA and SCL pins on the BIOS chip.

Does anyone know where this chip is located on the MOBO? I would be hugely appreciative if you would be so kind as to point me in the right direction. Thanks in advance!

 

Found these in my camera roll while looking for an unrelated picture. More pictures in the comments.
