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.

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.

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 think I will end up removing some of the sand at the sides eventually, I liked it better with the sand just in the center.

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.

I decided to take this weekend to tear down and rescape my 20 long, which got me looking back through some pictures of when it was in top form.

I'm planning on going with a Reverse island (?) or valley type layout this time around.

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!

Same here. I subscribed to release notifications over on github too.

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

Yeah, I do kinda feel like I'm commenting more on posts that I wouldn't have commented on over at reddit. Not sure why, probably has at least something to do with tje fact that I want to contribute to this place. I think it's also that people on here do seem to be more laid back and less confrontational over things that don't call for a confrontation. I like it here.

I've tried just about all of the current apps that are available for lemmy over the last two days and so far liftoff feels the most like a usable app to me. To ve fair, I know that a lot of rhe apps I tried are still in alpha or beta, so I'm not trying to talk bad about them, I get it. Liftoff is pretty good though.

[-] B20bob@lemmy.world 5 points 1 year ago

Bro, I've been trying to figure out why this poor guy would possibly need to meet these requirements.. I think you nailed it on the head. lmao well played OP.

Sadly, rmayayo has said that he will not be working on a boost app for lemmy:
