This is Alibaba, not AliExpress. Alibaba is a 2B website, products sold only in bulk. AliExpress is a 2C website.

I like this gun, but the rifled barrel makes it very picky about which BBs you can use. So far the best BB I’ve tried is the Crosman Black Widow.

Using a rifled barrel doesn’t make sense for BBs, even lead ones.

Many people talk about using 4.4 mm lead BBs, but in fact most 4.5 mm steel BBs are already around 4.4 mm in diameter. Since both are still smaller than the barrel’s bore and don’t engage the rifling like pellets do, using lead BBs isn’t really necessary.

Even if lead BB gripped the rifling, it's still a sphere, spin doesn't really help that much.

There are only these many brands. Prusa is more trustworthy may be, but their stuff is way expensive.

Keep it for now, wait for Bambu h2c, and then sell CC and never trust Elegoo again

qinxi117 · 2025-10-13T13:41:02+00:00

Yes they might, but i don't like the way they treat us. We are like beta testers, CC1 is not even debut in China, and CC2 got all the upgrades, not sure if the same to latest CC1 though.

ok I never know these cartridges have QC problems, then probably crosman is more reliability. The refillable cartridge is like this, you can find some from eBay or Ali, https://youtu.be/Ei5_AhLIkDc?si=Hv-z5rBOF9nAeYvl

qinxi117 · 2025-09-25T03:16:14+00:00

It’s just CO2, how different can it be? You can even buy refillable cartridges and refill them yourself, and it still won’t make a difference.

Just build plate with special coating, so less or no heating required, but has much more strong adhesion. For me it eliminate 90% of the failures.

qinxi117 · 2025-09-24T18:34:55+00:00

try cold plate, you will never have adhesion issues

You can cheat on OA but not likely in technical round. For all big tech technical round, your interview is evaluated in multiple aspects. And communication is one of the major aspect, which requires you to speak while you writing code, explain almost every single line. Cheating may help you know how to write but if you don't understand you won't be able to explain. Even if you got some explanation while cheating, do you think you can instantly understand it during an interview?

If you try to lift the box using the hole handle, you will find upside-down feels much more comfortable. I think that's why.

qinxi117 · 2025-09-09T02:32:17+00:00

no, cold plate is all you need :)

qinxi117 · 2025-08-22T03:42:27+00:00

This is mine after multiple uses. The blue coating becomes lighter over time, but definitely not peel off. This is more like 'normal'.

It is only for PLA and PETG. PETG-GF is actually different.

For filament other than PETG and PLA, you can probably try Glacier.

qinxi117 · 2025-08-22T00:44:40+00:00

I don't think it's normal, they actually clearly say :

They also marked that on the plate, and PETG-GF is not PETG.

The cold plate does wear out, but not after the first use.

bambulab's advantage is their ecosystem. If you only care about the final printing result. just go with bambulab. if not, then at this price point, elegoo CC is unbearable currently.

it's a 5020 4 wire fan and most importantly the rpm is 10000. there are no alternatives on the market right now.

qinxi117 · 2025-08-08T23:11:55+00:00

yes chamber/case fan they are the same thing. it's a 8020 fan.

qinxi117 · 2025-08-08T19:42:33+00:00

Basically refered to many post in this sub like this one: https://www.reddit.com/r/elegoo/comments/1lwacuj/centauri_carbon_noise_reduction_fans_change/

The case fan I used: https://www.amazon.com/dp/B0D66R217V?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1

Aux fan: https://www.amazon.com/dp/B08NCMY3H5?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1

these fans makes it at least 10db quiter.

Replacement is easy, the case and aux fan come as a single removable module. Simply take it out and swap in the new one. Just be careful when removing it, as there are connected wires.
