Ender-3 V2 safety upgrades (ferrules, PSU ventilation holes, mainboard fan, flexible PEI sheet..)

[@abbas2qaisar]

Love u, sir. U don't know how important this video is for my Ender 3v2

[@ScootLogix]

Very well done. Just dusted off my v2 and started printing again today after a year. I've only let it print overnight like once or twice but it always keeps me up knowing the risks. I plan on doing these upgrades. For now if I have print late at night I just use the pause button and let it cool down and pick it up in the morning.

[@zezzyzooze9476]

can you show me what a long pause can do to a print?

[@avejst]

Great walkthrough of the process 👍 Good points with regards to power supply and fans. Thanks for sharing your experience with all of us 👍😀

[@rudolfturo9888]

Hasznos es igenyes video, mint mindig! Koszonet erte!

[@GabrielAlejandroZorrilla]

Love this channel, on par with the ones like CNC kitchen or Thomas Salander (sp?). Keep up the good work! Cheers from Argentina.

Thank you for kind words!

Great video! In English, we would use the term "Scraper." A Spatula in English is used for the kitchen implement you would use to flip a fried egg.

[@backgammonbacon]

A spatula is a broad, flat, flexible blade used to mix, spread and lift material including foods, drugs, plaster and paints. In England not everyone is an expert in their own language and the meanings of its words, they also can't be bothered to check such simple stuff before posting "advice".

[@GarethLewin]

@@backgammonbacon Igor said in the video that he wasn't sure how to say it in English, so I answered him. I stand by my answer. Take google images as an example of what the typical image for a "Spatula" is, then search google images for a "Scraper" and see. I wasn't correcting Igor's English, but rather answering his question.

To the mainboard fan: There are also ferrules avaliable where you can put two cables in one, might be useful here

[@MyTechFun]

Hm, yes, probably I could place 2 wires from fan into one ferrule and crimp it.

[@bryanst.martin7134]

@15:52 : You have a recirculation of heat now. A diverter to flow the exhaust away from intake is preferable.

[@thelimike]

It shows you care, excellent and thank you very much…..

[@edaltounian7118]

Excellent video with great tips! Another one to add would be the cut out center bar that the wire run across. There's a piece you can print from Thingiverse to cover the sharp metal edges so it doesn't ever cut into your wiring harness. Also, the PSU cover can be modified like you did (and like I was originally planning to do) or you can print a small cover that just covers the wires at the bottom. You can't see the cover is missing from the top. Very nice video though and this should be pointed out to everyone who is just getting started. Flex beds are the best!

Thank you very much

[@mrmechano]

i completely removed the black cover of the PSU and designed and built in PETG a cover for the 220v wires and IEC connector. I also reduced PSU fan speed with miniature DC-DC step down buck to drive it at 12-15V to make more silent.

[@dy1an]

I removed Creality's cover from the PSU completely, and am currently in the middle of printing a replacement that has vents. This is the only thing I've printed with the cover off, but so far, the fan has been on for only a fraction of the time it was before. I also printed some feet/risers for the bottom of the printer, so that it's around 20mm higher off the table than it was before. I'm hoping that will let more air get to the underside of the printer and take the strain off the fans.

[@PaulTait2020]

Hi Igor. Thank you for making and sharing your videos. Also, you do know when doing the shrink wrap on the wires you can heat the shrink wrap with the shaft of your soldering iron. You dont need to you a lighter. Just in case you didnt know this.

[@MyTechFun]

Yes, I noticed that in recently watched videos. Thx

[@MateuszRulski]

A great vid! Thanks!

[@tanujak98]

great video. My prints really adhere strongly to the glass bed on my ender 3 v2 sometimes.

[@bryanst.martin7134]

PVA coat it first.

[@brianp1179]

I put my glass in the freezer for about 15 minutes and the parts come off very easy.

[@1dboucher]

I have found that baking paper works well for this, especially at higher heatbed temperatures

[@robberd7devos]

7:15 I don’t know a lot about electricity but wouldn’t this make the hotend cooling fan turn slower ?

[@RestorationAustralia]

Szia, eggyet ertek ezekkel az upgradekkel. Ugyes megoldasok. Nekem is van egy ilyen gepem es az eredeti rugok nagyon vackok tenyleg erdemes atcserelni.

[@grasug8550]

I'd be very interested to see a comparison between the original springs of the Ender 3 v2, the yellow springs of the Ender 3 v2 NEO and the actual upgrade yellow springs in this video.

[@backgammonbacon]

Dude get on to banggood to send you a new set square to review

[@MyTechFun]

:-)

🖖 👍

[@emilcioran7444]

I never messed with anything electrical do you recommend me doing this safty upgrade? I sure would like to.

[@WaschyNumber1]

Does anyone know wher this plain 3M Temperature Conductive double sided stickers without the magnetic plate are sold, or what's ther propper name is, I looking for them quite a time and can find them. 😔

[@StuElliott1980]

Do you mean Scotch (3M) 468MP double sided high temp? It's available on eBay.

[@WaschyNumber1]

@@StuElliott1980 yes something like that, thank you very much 😊
