Anycubic Kobra Plus Review

Cura, by default, prints the infill first and then the outside walls, so an easy/fast way to improve the outside walls quality without increasing them is to disable the option "Infill before walls", that way the infill does not show through the walls

[@hjortmidtledsagerelsker2851]

I didn't know this, thank you 🙏 I use 3D Prints for mold negatives and while I quite like the pseudo-3D print look of the cast, I've always wondered how to mitigate against it. 🤔 Excited to try!

[@BobofWOGGLE]

Yeah they put lead in the gas to reduce engine knocking. Same guy who came up with that invented CFCs. Poor guy was just trying to help.

[@lanesteele240]

Lol. I just saw that on KZbin yesterday

[@tiporari]

It also helped lubricate valves and prevent damage to the valve seats. Not necessary anymore because we have better metallurgy.

[@ivanm.3522]

You should bring back the cheap crt cyberdeck build

[@50shadesofbeige88]

I'll second that.

[@olik136]

I think the small bumps in the surface (benchy) come from bad seam placement- so that is basically where the layer starts- there are settings to put them all in the same place- which makes a visible line- but the rest is completely smooth then

[@CaptainKirk01]

My parents had a gas station when I was a kid, I remember when it was less than 80 cents a gallon. Leaded additive helped with knocking. We still use it in small airplanes.

[@Knows-Nothing-14]

The zits on the benchy are in the same place because that is where the print path finished the layer and started the next one. You can specify the z seam placement or pick a random start position to minimize this effect.

[@youbecha64]

The 'lead' in leaded gas controls 'knock' (pre-ignition) which allows engines to run higher compression and create more horsepower...now it is done with a stack of electronics to measure how much knock is occurring and detune the engine to make it go away. (an engineer will have a more precise definition)

[@lasskinn474]

There was something about lubing valves too as a reason to use it. So some engines couldn't use unleaded initially without changing valve seats. For octane rating(/compression tolerance) they started using other chemicals so in regards of that the unleaded isn't worse and you don't need knock detection as such just for the change to unleaded

[@youbecha64]

It is true, in the long term, valve seats were required to be hardened to convert to unleaded...but not sure what metallurgy was in place. The other portion is fuel octane...that is also measured by modern electronics, and is part of the engine math to reduce knock.

[@bertieblob3387]

Measuring the grade of the fuel was done by measurement in a special one cylinder engine, of which there were only a handful in the world. Until they in-lined the process, they used to put in extra lead to ensure they met minimum requirements for the particular grade. It was called it ‘throwaway’ at the time. It was an expensive practice, which they were glad to fix. Fortunately it’s use has been largely abandoned now, so just a little piece of our interesting history now.

[@henzik]

This is also a good video about the lead in fuel: kzbin.info/www/bejne/f4eWlaGCr9mbeqM&ab_channel=Veritasium

[@1pcfred]

@@bertieblob3387 the octane calibration engines you could advance the timing to see when it knocked and from that figure out what octane fuel you had. You can advance the timing in any engine but on the calibration engines the timing was calibrated. Power timing!

[@olik136]

there is a setting in most slicers to compensate for the elephants foot- the only thing it does is put a champ at the bottom of the print by offsetting the outer lines to the middle

Can u do a tutorial to setup Curia pls

[@steameier8590]

Which 3D printer with direct extruder is bigger than the small cobra and has autoleveling and is fast&silent?

[@epi2193]

I don't understand why they went back to the glass beds after introducing the pei sheet system on the vyper.

[@tiporari]

Hey Ben, why not make an adapter that goes from MicroSD to full size SD. A short ribbon cable, a sacrificial microSD card, and a remote SD card slot. You could then locate and orient it whichever way you wanted.

[@ADBBuild]

Wiping the bed down with alcohol before starting the print helps adhesion a ton.

[@UpLateGeek]

Yeah, it's impossible to design this with a full sized SD card slot. That would cost them 15 cents more. Actually more of an issue is sourcing garbage generic SD cards vs micro SD. The cost difference there is probably a little more. I completely agree though, full sized SD is more flexible, since you can just use an adapter to micro SD if you want. Anys ways, I also prefer direct drive and a PEI steel sheet for the print bed. I do need a larger 3D printer, so I should really just do some research and buy one.

[@drewscruis]

Lead was used in gas because the valve seats and guides in the heads were made out of a softer material. The lead acts as a lubricant for them.

[@Tenfey]

I will never own or operate a 3D Printer, but I still watch all of these.

[@androxilogin]

Wondering if you've ever tried salt water on glass beds. I use it on my Alfawise U20 all the time and it works great without leaving any noticeable marks on my print. I also had glass beds on my CR-10 minis but instantly upgraded to Garolite I ordered from McMaster-Carr which does an incredible job with adhesion but you have to be extremely careful while leveling or it will put permanent cuts in it just like a PCB board. Both release parts extremely easy upon cool down. For the minis, all I had to buy was a 12x24 sheet for around $30 and cut it down the middle. Interested to hear your thoughts on salt water and Garolite; if you've used them and if you have, if you were happy with the results.

[@yojoehojo4291]

Hey Ben! I used to watch your Ben Heck Show back when you were making things like the N64 Handheld. I was wondering if you could help point me in the direction of anything that would be usefull for a project I want to undertake: I'm trying to make an Arcade Stick Box out of the guts of a Nintendo Switch Pro Controller, having it be completely functional for any game. I'm having trouble finding the analog stick pinout details and also I realize I need a board to convert the Digital Joystick output into an analog stick output so it can be plugged into the pro controllers board. I hope you respond!

[@stobe187]

you could try to mod some noctua fans in there perhaps?

[@tarakivu8861]

Noctua is wayy to expensive. If you can run your fans a bit slower, you can do it with a cheaper fan. Noctua only makes sense if you run them on high-speed. Then they are more silent than others.

[@tristanglidden581]

Lead was added to gas to help prevent engine knock back when fuel qualities were much lower than they are now.

[@Iamwolf134]

Improved metallurgy over the years eliminated the need for lead in fuel.

[@fooman2108]

Tetra-ethyl lead was used to prevent the old NON hardened valve seats from wearing on the heads of motor. Lead is still available on aero-engines and high test (over 100 octane) fuels.

[@cryptomnesiac]

There are those Noctua fans known for being quiet. Ppl upgrade their Ender 3's with them all the time. Could be a potential option?

The stitching is probably layer change. If there’s a setting to align them or place them in the same location, it will at least look uniform and intentional.

[@bknesheim]

Maker Muse has released a video with 5 slicer default that he change where he show that the starting point for a level is what make the little knobs. Changing it to be in a line make the overall look of the print better.

[@moosemaimer]

One of the case fans on my computer has a bearing that's going, I have to tap it to shut it up... I would replace it but good luck finding 230mm fans that aren't stupidly expensive or glow garish colors to boot.

[@planetfoxdotnet]

The thing about the portable Atari Lynx reminded me of a project I’ve been thinking about for a while: a portable Game Gear. Like if you take one apart it’s mostly air and batteries. If you printed a new case for it and replaced the six AAs with a flat lipo you could make it way smaller and a lot more practical, or at least as practical as a 32 year old handheld console can be. If you printed it with that crazy pink filament you could call it the Glam Gear.

[@Thepuffingyank]

leaded gas was used for antiknock

[@1pcfred]

Tetraethyllead was used to increase fuel octane. So yeah it would reduce knocking. As Ben said it did help with lubrication too. You didn't need stellite valve seats when you ran leaded gas.

[@fredleckie5880]

Lead was used to stop the "knocking" - when the pitons misfire

[@ovalteen4404]

Its primary use is octane boost, but it does help with knocking too. It is NOT a lubricant. In fact, if TEL were the only additive, the buildup of lead would leave sludge everywhere. So they also add scavenging compounds which combine with the lead to make PbCl2 and PbBr2, both abrasive white powders that can be flushed out with the rest of the exhaust.

[@ray73864]

I gave up trying to get Cura to work for a Voxelab Aquila, it's basically the same printer as the Ender 3 v2, but no matter what I tried, I couldn't get it to work with Cura. Went with PrusaSlicer instead, worked perfectly first time after I told it that it was an Ender 3 v2, extremely minimal configuration required. Every print comes out so much nicer, though I dislike Prusa's supports, but at least I don't have to junk so many prints.

[@briandicinti9535]
