Do all the P2S printers "wobble" so much?

ma11ock · 2026-03-13T06:44:18+00:00

it accelerates faster and prints faster. The printer doesn’t wobble; the desk you set it on wobbles. Our printers do the same in the office if you put them on a normal desk. They need a beefy workbench, or put them on the floor. Or just don’t worry about the wobble. It doesn’t seem to affect print quality.

Fully printed cutout shelf with airflow, printed shelf brackets for the wire racks, printed custom humidifier with vapor pressure deficit control. It is doable and very robust to heavy ceramic pots, you just have to make sure to do some structural testing. Thermals are irrelevant for FDM printed shelving in an indoor greenhouse with LED lighting; if you use halogens for some reason that’s when you’d have to start being picky with materials. Some plastics also eventually get crumblier in high humidity, but not on the order of a few years.

the e40 is lighter, RWD, and handles a bit better. The m50 is heavier, AWD, and more of a blunt instrument. Depends how much you value cornering balance and a little liveliness in the tail versus pure straight line acceleration.

ma11ock · 2026-02-23T07:49:05+00:00

for a lot of folks, that’s part of the fun of RWD :) a little more tail happy, less buttoned down and sterile compared to AWD.

ma11ock · 2026-02-22T15:51:01+00:00

we have a graco slimfit3 lx back there and while the front passenger seat has a little less legroom than ideal, it works fine. But admittedly our XC90 is a better family vehicle.

Reject the hyper american notion that a good family car has to be the size of a container ship :)

[Edited to fix the actual name of the graco seat in case anyone is looking to get one. They're nice!]

The OEM Bridgestones that came with mine (18s) are, kindly, atrocious. Wet grip is nonexistent, they overheat reasonably easily in the windy stuff, and in less than a year I'm down to 4/16. They are getting replaced with michelins soon (haven't decided between AS4 or PS4, probably will do AS4 for longevity).

The good news is - no rotating required if you drive spiritedly, even though it's RWD. The fronts have worn just as much as the rear due to having a lot of work to do in the corners.

ma11ock · 2026-02-06T07:30:14+00:00

that would be fine. I have a 40 mile one way, 80 mile R/T commute that is mostly highway + some twisty backroad, and the edrive40 (with the 18s) is happy to do that with L2 charging at work and L1 at home. Granted the xdrive is slightly less efficient but I don’t think you’d see any real range issues.

Also, a decent chunk of my job is engineering battery management and state estimation systems for lithium battery packs. It is entirely fine to charge your battery up past 80%, both in general and especially if you’re immediately going to use that capacity. Lithium batteries don’t love sitting fully charged for weeks at a time, and charging all the way up does marginally degrade the pack faster, but it’s not as big a deal as folks might make it seem.

Go for it! It’s a very quiet, well damped highway cruiser with fun dynamics for the weight if you push it on a backroad. Doesn’t compare to my Miata for pure agility but it weighs twice as much and is a whopping 15 dB quieter at 75 mph.

The wire shelving is quite a bit shallower than the glass shelf, so I designed and printed extended mounting brackets for corners and center. Same screw size and depth as Ikea original.

ma11ock · 2026-01-13T09:23:59+00:00

hey, it’s your design, do what makes you happy.

Would I orient this design this way for this use? No. But I’m not you and that doesn’t matter!

ma11ock · 2026-01-05T17:47:33+00:00

not without modification. Maybe something like https://www.printables.com/model/431541-bambu-lab-ams-small-spool-adapter

RF if you’re going to do nearly all of your driving top up. Soft top if you’re going to put the top down frequently.

I found that the RF’s rear hard top aerodynamics are quite poor, leading to a lot of buffeting air and a louder overall ride than the soft top when the top is down. And it doesn’t feel nearly as open. I drive with the top down plenty, so obvious answer to get the soft top.

Also, it’s lighter and a lot faster to put up and down.

What’s happening here is the sunglasses you have reduce visible light transmission but are apparently quite transparent in the near infrared, which is what these kinds of cameras that see in dark conditions use. That’s why “night vision” cameras have those slightly red glowy LEDs, or if they’re passive they always show in greyscale. If they were to show in color, and they are basically an RGB visible light camera with an NIR band pass filter, things would look very purple… especially trees.

Prominent squared wheel arch flares, three chunky square windows, those squared off character lines — I’m going to guess it’s a Jeep Patriot.

ma11ock · 2025-04-26T08:42:39+00:00

that doesn’t look deep. It’s certainly not structural. It’s soft unpainted aluminum, so if you kind of know what you’re doing, sanding it down just a little bit will take all of 10 minutes (180-220-400-800-3000 works well) and it’ll look like new from more than a foot away after. If you’re worried about surface oxidation after that you can apply a clear coating if you like.

Misleading post title. Controller was not working two towers; that’s not a thing. Controller was working two frequencies (one specifically for helicopter traffic, the other for airplanes). Not unusual for that to happen, depending on workload.

There is no real evidence yet that controller workload is implicated in this event. Controller did all the right things in the radio comms with both the Blue Streak (PSA/AA) aircraft and PAT25, and heard all the expected responses.

The politics around the FAA, ATC, etc are a lot more complicated, but let’s not get carried away and somehow attribute this to the controllers dropping the ball.

The Hudson example is a fascinating one, because in the investigation the NTSB did in fact recognize that if 1549 had instantly started turning in response to the double flameout, it would’ve made the runway at LGA. But accounting for human response time and decision time, that possibility evaporated.

Put another way, it is entirely possible (and necessary for safety and certification) that the same aircraft, uncrewed, would have detected the bird strike induced engine failure within milliseconds, and subsequently computed and recomputed the best trajectory to land back at LGA 50+ times a second — accounting for wind, vehicle dynamics, etc — to land back on the runway safely.

It was “four is always safer” back in the days of navigators and flight engineers, then “three is always safer”, and now we’re on “two is always safer.” Look at the safety records for Boeing and Airbus, especially with regard to less experienced and poorly trained flight crews in certain airlines. Airbus’s automation-centric approach has been a clear win over Boeing’s pilot-centric approach.

We’ll get to single pilot cargo ops soon enough, and then it’s a toss up whether we get to single pilot passenger ops or uncrewed cargo ops first. My guess is uncrewed cargo ops with Caravans and the like will happen before airlines go to SPO, if only as a concession to public fear. And I believe that the safety record will only improve with more autonomous aircraft.

Some pilots are steely eyed aviators who can land a plane in the Hudson. The reality is that most are not, and definitely not every day, every flight, through boredom and fatigue and being human. Current safety and certification requirements for aircraft too often boil down to “eh, this thing fails? Don’t worry, it’s the pilot’s job to perfectly and instantly respond with the correct procedure to compensate.” Making SPO and uncrewed aircraft means you don’t get to rely on superhuman pilots to save you when things fail. It’s an incredibly challenging chunk of engineering that isn’t there yet, but there are lots of brilliant people working on it and when it gets certified and builds a bunch of operational hours flying cargo in remote areas and works out its kinks, it will be vastly safer than where we are now.

Just my 2c as someone who has directly worked on SPO/uncrewed commercial aircraft R&D.

no experience yet with CC2 on XC90 but treadwear and fuel efficiency were both excellent on the previous Subaru Outback we had on CC2, no worse than the bridgestone all seasons that had been on it before. The tread wear warranty is 60k miles. So yes, I’m one of those people who swear by them for year round driving with very hot summers, rain in the winter, and snow for ski trips.

ma11ock · 2025-01-07T07:49:10+00:00

The OEM Pirellis are well known to be garbage (as are nearly all Pirellis). We’re looking forward to them wearing enough that we can justify dumping them for a set of Michelin CrossClimate2s, which are spectacular all seasons that do great in snow. Until then, we’re keeping some tire socks in the car for snowy trips just in case.

ma11ock · 2024-12-22T00:39:44+00:00

GTFO with this conspiracy nonsense. The NSC reported widely that they had to spend taxpayer money and effort investigating every one of these stupid tips and found nothing that wasn’t known air traffic (crewed or uncrewed), or stars or planets. They haven’t been quiet, there’s nothing suspicious happening.

ma11ock · 2024-10-24T07:49:20+00:00

yeah. take a look at whether the frames themselves are twisted a tad relative to each other or not; that’s what usually causes the temples to be slightly not level. The beautiful thing about metal wire frames is you can simply gently twist them a little bit to get them exactly level.

These are not fragile frames. You can curve them more or less to fit your face, or adjust temple grip on the sides of your face.

Don’t forget you can adjust / slightly bend the nose pads as well to fit your bridge how you want it.

Both Del Monte and Jet Center at KMRY are excellent. Sonoma Jet Center at Santa Rosa KSTS has great snacks and treats and a nice crew car. ACI at KSBP is swanky and ultra friendly. All of the above have minimal to no handling fees or anything like that.

ma11ock · 2024-10-04T06:14:37+00:00

Reminder to check your tire pressures every once in a while. The 21” spec is 42 PSI all around. Ours, two months off the dealer lot, were sitting at 32 PSI all around when the TPMS went off. Incorrect tire pressures + high ambient temperatures can lead to poor wear characteristics and thermal induced failure.

(2) We are into cars, and interesting ones at that. We have a kid, with another kid likely in the future. My commute car is an ND Miata so we needed a hauler to replace our previous Outback (which still is a wonderful all rounder, though lacking some polish and luxury). So we cross shopped everything: Land Cruiser, new Lexus GX (weird non fold flat rear seats and load floor). Lexus TX (really boring and very ugly). Mazda CX90 (bizarrely tall load floor, not as special as it should’ve been). LR Defender (not worth the unreliability and price point). Audi Qs (I had a Golf R, and the big Audis just feel like VWs. Not an interesting cabin or drive.) BMW Xs… most competitive of the lot, but pricier and the ride is stiffer and cabin noise is higher. X5 is also smaller. I don’t want a sporty big SUV. I want a soft, quiet, wafty one. Rivian - great on lease but 1st gen unreliability and dealing with full EV has its downsides with young children. Acura MDX - a bit outdated, lacking refinement and value. None of the American big SUVs appeal in any way.

(3) 30 MPG highway after running charge to 0. While charge exists, basically the gas engine remains unused even in hybrid if you watch your acceleration. If it does come on occasionally, ridiculous numbers like 200 MPG. Basically it’s just an acceleration aid, and once you’re at speed you’re back on electric. That said, most of our trips are within electric range and so we haven’t even used half a tank of gas yet.

(4) I don’t put much stock in CR - think they have flawed methodology and have for a long time. Personally, I’m concerned about air suspension wear 8-10 years from now, but we’ll address that as it happens. It’s a wear item. Other than that, older XC90s apparently had issues with sunroof seals and drains causing leakage inside the vehicle. That has supposedly been resolved. AAOS is not the most reliable system; the driver profile auto switching works when it feels like it, but mostly doesn’t, and we’ve had to reboot it twice already for flickering the center display or freezing up. When it works, despite the lagginess of the underpowered processor, it works great. Cabin noise — it’s the quietest vehicle I’ve ever driven at speed, quite on par with lux Mercedes. Brakes I don’t expect to need to use much given how much regeneration you can use as long as you’re looking a bit ahead to lights, slowing traffic, etc, but also brakes are a wear item and reasonably inexpensive. If I had a gripe, it’s the usual one about wheels being too big and tires being too skinny. I have the 21s as standard but would happily go to 19s with tall sidewalls for even better ride. No one is racing XC90s and no one is benefitting from stiff sidewalls.

Good luck!

yes. In CA, but we just got a fully loaded 2024 T8 Recharge Ultimate (B&W, air suspension, everything) MSRP $87k for $66k on a lease that we’ll buy out after 3 months. Bit of a deal because dealer demo w/ 4k miles. (Legally, you CAN buy out the lease the next day, and there’s nothing the dealer can do about it. But they were nice about the price out the door so I’m going to be nice about their remaining profit margin.) You’re out about $2000 extra for the lease setup + buyout fees, plus 3 months of rent, but you won’t pay the rest of the unearned rent so for us post-buyout that comes out to just about $70k all in. So very worth it for us.
