I replaced the second Pic with a less potatoey one

One ring would likely be enough, but I don't want it to fail. They're 3/8 rings from a cheap kit that I picked up after one of @Ryan 's posts on making DIY bungees.

Ok, i went back and read the article, but i didn’t see a reference to the hog ring kit. And what size heat shrink did you buy?

This was done with an old kit, probably bought from harbor freight 10 years ago. I'd have to go measure, but maybe 3/8? No adhesive and it's probably 2:1. Anything will do for this use case as it's just there to cover the rings

This is the hog ring kit Spurtar Angled Hog Ring Pliers Kit with 360pcs 3/4" 1/2" 3/8" Hog Rings | Spring-Loaded A3 Steel for Upholstery Fencing Animal Pet Cage Craft Bagging Netting Trap https://www.amazon.com/dp/B0DCG3HWHL?tag=atomicindus08-20

The four heads on a u1 is cool and would be perfect for Multicolor models. Do they have a material management system or is it one spool per head at a time?

Personally, I would jump past the p2s and get an x2d. Dual heads covers the benefit of different support material and it can do some Multicolor. An AMS unit for the main head and a Sunlu S2 for the secondary would be a sweet setup
Looks like it's around $900 with the Bambu AMS. I don't know how much multi-material printing I'll do but it seems like that could be nice to have. The heated chamber on the X2D actually looks like the standout feature for my uses over the P2S.

Even a P1S can do engineering filaments. I've done prints with 100 degree bed temps and 270 degree nozzle temps in mine.

If it was me, I would go with either a p1s or x2d. The p2s just doesn't feel like it fits well between the two

I'd love to be able to do a second material for supports

At current prices I would go with X2D, the extras you get for $100/150 over a P2S are worth it. This coming from someone with two P2S. I bought the 2nd during the last sale when the extra $50 off ($700 for the P2S) between the 2 models was worth it, plus availability for the X2D was limited to Bambu direct at the time. Not sure if they are dialing in the P2S retail price a bit more now since they kept it at $750. Buying from local big box store or ship to store can be a bonus for easy returns pending how your area shipping companies are, as some of the units from Bambu tend to get kicked around.

You might check out the Creality K1 plus as well. They have things like the heated chamber you need for engineering materials. It also has a good build size (350x350mm). With filament changer it's $900 on sale (check the various deal sites). A drawback vs the X2D is it uses a conventional filament change. However, I think the print speeds are faster than the X2D. Not night and day different but faster. However the speed advantage might be with pla where printers can go all out. With other materials your speed may be limited by the material itself.

If you just want to try things out, go for a deal on the Flashforge 5M or 5M pro. They are great printers and the open frame 5M can be had for $150 if you are ok dealing with AliExpress. The enclosed model is about $80-100 more. Great printer but the build are is small for many automotive parts. However, it's a cheap starter printer and even if you get a bigger printer later, the 5M is still likely to be faster when printing PLA. It would make for a good second printer.

Are these any good? Reason i ask, when i pull my spools out of the sunlu drier the control panel shows humidity aroud 15%. I put the spool into a ziplock back with a sensor,band when i check bsck 2 hrs later the thingie shows close to 30%. I wait about 2 hours to give the device time to stabilize.

Can’t speak to those specifically, but I own many similar. They are not terribly accurate and only read as low as 20%.

I haven't bothered with sensors. My rolls go from a drier to a ziplock bag and back to a drier.

At that price they can't be accurate and reliable

Did not know that. So when i see videos of people printing accessories for ceral containers and they include a slot for a humidity gauge … that's not useful?

We use that style of sensor a lot, maybe a few hundred of them, they are very accurate and reasonably reliable. We have run tests against lab grade instruments and they met their accuracy, repeatability, and linearity specs. The batteries they come with don't last long, so order replacement batteries as well. They are a lot less expensive on Temu, and the sensors seem to all be about the same among brands. The sensor is electronic, that's how they get the accuracy, repeatability, and low cost.

I printed 24 of those cereal boxes. My takeaways: They do a good job of keeping filament dry and are easier to get spools in and out of than a ziplock bag. Plus they look cool. The humidity gauges are near worthless. Your desiccant changes color when it needs to be dried, which is indication enough. I've switched away from the desiccant trays that sit in the bottom of the cereal container to the cylinder shaped ones that mount in the center of the spool. Reason there is that I have a Sunlu dryer that replaced the lid of my AMS. It runs while I print, so if the desiccant is in the spool, it also gets dried while I print.

Price is rarely completely indicative of quality anymore. Those sensors are very accurate, it's an electronic device that sells in quantity for pennies. You can pay higher prices but you aren't likely to get better accuracy or reliability unless you are paying hundreds for a lab grade instrument.

What do you use them for? I find if I have multiple in the same location, they will have different readings. There have been multiple in my AMS the last few weeks and there's a 10% range.

Monitoring humidity and temperature in manufacturing environments as well as shipping environmental monitoring. We also use them in environmental chambers for testing, when the testing will ultimately exceed the ratings and destroy the sensor.

Humidity will vary, even over fairly short distances, and any air flow, heat, etc. will affect the readings. Any sensors will give different readings if not subject to the identical environment. 10% is a big difference, are the batteries weak? Or maybe the ones you got are different. What are the specs on the ones you got?

I have had those exact ones for 3.5 years and they are good enough for 3D printing purposes. Mine are all within a few percent/degrees iirc. Yes, they take some time to equilibrate (2 hours seems a little long, though), but remember, ziplock bags are not going to keep moisture out.

Get some plastic cereal containers, but you have to keep desiccant in them. This works. I've been doing it for years.

Edit- someone mentioned that they don't go below 20% humidity. Mine go into single digits, but the air needs to be dry :p

Three separate orders from Amazon:


All purchased fairly recently, but I guess that doesn't necessarily mean the batteries are fresh. It's been my experience that I could leave two sitting next to each other and they won't read the same.

Bambo Lab WAS one of the most popular 3D printer around. I say WAS, because they are in a serious online ******* CONTEST ! A couple a YouTube "heavy hitter" are ganging up on them and things do not look good ! At a minimum, very bad publicity.

That is true for lab grade instruments as well, humidity will vary in the few inches of space between them. Not 10% but potentially a percent or two.

Also they typically do ship with weak batteries, unless you happen to get a just-manufactured batch. They cut costs on the batteries, we always replace the batteries before using them.

Are you referring to the old news/false claims about internet security?

Yes, Bambu's are the most popular 3D printers around, and I see no evidence that has changed.

Details? Multiple CAPS and !!! sounds serious.
This seems to come up now and again, but so far, nothing has actually knocked them down too much. Mostly fearmongering by some talking heads, and not people who actually use the machines.

I have learned to take most of that user's posts with a giant container of salt (he moved past a pinch a while ago).

2 hrs cuz i had other things to do. My point was, i knew it wasn't like an instant thermometer.
I wasn’t aware ziplocks were permeable.

So your evidence is a 2month old video, where he references something that happened over a year ago? That isn't breaking news... This guy has continually attacked Bambu, but it hasn't actually had a dent in their sales, from what I have seen. Even the guy who made Orca said he didn't want to fight Bambu, just wanted to make a point.

Again, Mostly fearmongering by some talking heads, and not people who actually use the machines.

You can not like their policies, but calling it
serious online ******* CONTEST...things do not look good... very bad publicity
Only makes sense if you actually believe that guy (and his PoV), who doesnt seem to actually do anything with his tech knowledge but attack others. It isn't having an actual effect on their sales, or user base in a meaningful way.
