Dear Amazon,

I don’t want to spray this in my kitchen…

Design flaws

Slight revision to my earlier comments about the external spool holder working perfectly. It has one flaw: when a brand-new spool is loaded, the mounting angle puts enough of a twist on the filament that it’s possible for it to slip over the outside edge. It can’t get tangled, because the arm is in the way, but it won’t feed as smoothly.

My quick fix was to just put something inside the Cambro that was big enough to keep the filament on the reel. Tomorrow, I’ll design and print a clip-on filament guide to ensure it stays on track.

Meanwhile, the Sunlu PETG prints pretty well (shiny!), although I’m still tinkering with the settings a bit to eliminate stringing.

I got an angle

I did have to change one PrusaSlicer setting for one of my common test prints, the baby takadai koma. PS supposedly attempts to pick the best angle for supported overhangs, but in this particular case, it does nothing at all, and uses the same angle regardless of the part’s orientation. Could be a bug in the 2.3.0 release candidate that I just upgraded to; if I scale the part to 250%, it changes the behavior on one of the two overhangs.

For now I’m just going to set it to 45° in my profiles, and double-check the print preview when I know I’ll have significant horizontal overhangs. One of the nice features in PS is the ability to define override zones for settings like this, either with bounding objects or layer height ranges. In this case, there’s only one pair of overhangs, so it’s easier to just set it globally.

Fuck off, Microsoft

Woot stopped scrolling in Safari, so I visited the site with Edge to see if there was anything interesting. It promptly popped up a coupon using Edge’s built-in affiliate system, informing me that I could save money for me and make money for Microsoft by clipping a coupon.

Um, no. Not now, not ever. One more privacy setting to keep track of, I guess.

Oh, and the scrollbars were broken there, too, so apparently Woot picked up a bunch of discontinued web designers for cheap.

April in Saga

Not me, zombie idol singers.

🎶 Don’t fuck with me, AT&T… 🎶

🎶 …the truth is, we all have left you. 🎶

I canceled DirecTV on 11/26. Following their instructions, I took the equipment to the nearest UPS Store for return shipping on 11/28. I got a receipt.

Good thing I still have it, because they just tried to bill me $155 for “Non-Return Recordable Equipment”. That’s $135 for the equipment and $20 in city and state taxes. (less the $8 credit on my account that they never refunded to me…)

I’m sure that next week they’ll send me a glossy color mailer offering me a special deal to become their customer again. Yeah, not gonna happen.

[Update: spent twenty minutes on hold, carefully spoke the 20-digit return confirmation number from November to the rep, and after 10 minutes of loading time, received a guarantee that the charge will be removed from my bill.]

Don’t eat the yellow ducky

I could print this Thing, but I have no snow to use it on.

Come to think of it, though, I did buy a rubber-duck ice cube mold some time back; I should try it out, now that I’ve got all the Omaha Steaks boxes out of the freezer. Oh, and the Death Star ice cubes, as well.

Asked and answered!

Macrumors: What do you want to see from Apple in 2021?

J: QA.

Not Batteries, Included

Somewhere in my holiday ordering, I bought myself a pair of third-party NP-FW50 batteries for my Sony A6500 camera, with included charger. They have pretty good reviews, and RAVPower has been around for a while.

Since I already packed them up to return them the same day they arrived, you might guess I’m not happy. One battery charged, the other did not. At all. I’ve bought their stuff before and gotten what I paid for, but this time, no.

I have a different brand of batteries coming for the WX800 next week, and I’ll be interested to see if that company has QA.

Why camera batteries, when I’m not really even leaving the house for the foreseeable future? Gift cards; I just started picking things off my wish lists.

There Will Be Zombies

Or at least, an announcement about zombie idols. On January 1st.

Well, that’s different

I’m in the habit of asking the nearest Alexa device to play songs that I don’t have on my laptop. The experience is unreliable, not just because it mis-hears me and plays whatever sounds close, but the one thing that’s always worked is the phrase, “Alexa, repeat the song”.

Until today, when instead of the most recent song, A Very Strange Medley, it reached back several weeks and repeated The Future Soon.

The Return Of Doctor Sue

If you have any remaining affection for the current incarnation of Doctor Who, the upcoming New Years Day special features Captain Jack Harkness. And Daleks. And a plot that looks to be recycled from a few Matt Smith episodes. I’ll pass.

First overnight print

This took about 14 hours. I haven’t tried it out yet, because there are a few more parts that didn’t fit on the bed.

Yes, I’ve finally printed a 3d-printer upgrade, because I decided that the hassle of rewinding filament onto empty Dremel spools was higher than the hassle of printing an external spool adapter and coming up with a way to keep it warm and dust-free. The dust cover should be trivial, since I’ve got plenty of connectors from my takadai project; I just need to see if I can keep it up around 30°C the way the internal spool holder does. One of these would be overkill, but since it would only run while I’m printing, I could plug it into the spare Amazon Smart Plug I’ve got sitting around. Or just pre-heat the chamber for a few minutes before printing, and keep a dessicant pack inside the dust cover.

Why is it purple? Because it was the only color in stock at a reasonable price while I was ordering some other things from Amazon. Dremel’s branded filament continues to have availability issues, which is another reason for me to make it easier to use third-party spools.

(and, no, I will not be using this filament to print a dinosaur…)

Helping Hands

Soldering isn’t the only activity that benefits from a set of extra hands. This set is sturdy, easy to print, and the grip strength can be adjusted by your choice of rubber bands.

There Will Be Dragons

Dragon Maids, to be precise. In masks, apparently.

(hmmm, the face-masks are gone from the promo pics now; maybe they realized that dragons don’t fear Corona-chan)

(no, wait, they’re back; they must be rotating the image)

M140 > M190

I solved my intermittent adhesion problem. PrusaSlicer was heating the bed with M190, which apparently doesn’t “stick” on the Dremel 3D45. The printer dutifully pre-heated the bed, but then turned it off, so it gradually cooled to around 36°C over the course of the print. Cooling plastic shrinks, so long, narrow items would tend to pop up at the ends.

Dremel’s version of Cura doesn’t use M190 at all, and just issues an M140 for pre-heating and another right before starting the second layer. PrusaSlicer supports custom gcode before layer changes, so I just added M140 S{bed_temperature[0]}, and all is well. It’s probably overkill to force it on every layer change, but it doesn’t hurt anything or slow down the print, and I can always refine it later.

Meanwhile, I’m pretty happy with the quality I’m getting:

Hatchbox PLA, 0.1mm, 0% infill, no supports, 230°/60°; Buddha, Duckie. The buddha really should have been printed with supports, but I decided to risk it. The duckie has some layer-start issues that I’m still tinkering with.

Dear Amazon…

2020-world problems

Santa was hung by the chimney with care…

This looks less like “coming down the chimney” and more like “autoerotic asphyxiation”.

Apple takes aim at a newfarmer’s market

Lots of coincidentally-identical rumors exploding out of the tech press recently, about Apple’s un/confirmed plans for a self-driving electric car Real Soon Now. Given that they can’t release a new OS without bricking thousands of their own products, I think it’s a bad idea to give them the chance to brick their customers, too. And non-customers.

Rewatch: Bofuri

One does not marathon Bofuri, one mainlines it. Fingers crossed that season 2 shows up sometime next year.

I’ve been having difficulty watching pretty much anything recently, with all the never-ending lockdown theater, but I was able to watch half a season of Maple’s antics at a time.

No Comment

I’ll be upgrading the comment system tonight. Should be a trivial outage, and it’s not like I get a ton of comments in the first place…

It scans

Given the Left’s ahistorical fondness for Guy Fawkes masks, I find it curiously appropriate that you can just substitute “Democrat” for “Gunpowder”.

Reread: Sunshine

Robin McKinley’s novels have long been a comfort food for me, and last night it was the quirky Sunshine, which carved out its own little genre, the vampire/bakery/buddy-cop urban-fantasy.

(yeah, I didn’t even try to find something that included all the relevant elements…)

Slightly more faithful than ‘Starship Troopers’…

…a Japanese live-action adaptation of Heinlein’s novel, The Door Into Summer:

Spamalot

Can it be coincidence that the volume of email spam I receive is increasing in direct proportion to the confidence that BidenHarris will take power soon?

It’s the worst sort of obvious crap, and it’s all getting past Gmail’s spam filtering before being caught by mine. This is maybe half of what arrived yesterday afternoon:

A Wild Gravity Ratchet Appears!

Back in April, I put a deposit down with BraidersHand for an ayatakedai (綾竹台) conversion kit for my takadai. Unexpectedly, it arrived on my birthday, which was a nice surprise. (note that their waiting list isn’t usually that long for this particular item; my order accidentally got dropped from the work queue, and I didn’t check up on it until November)

The takadai straddles the line between braiding and weaving, while the ayatakedai is firmly on the other side, kind of a warp-weighted tablet loom. Warp threads are manipulated in groups to open the shed, through which two weft threads are passed. The threads are wound on separate kumihimo bobbins, and then the warps are tightly twisted and moved up/down the “feathers” to open the shed, or across to change the color or pattern. The wefts just hang over the side arms, without any twist.

All of which is a lengthy side note, because what I was actually interested in was finding someone who had replaced the standard chopstick brake on the take-up reel with a gravity ratchet:

Cozier Than Thou

Perhaps the real reason Democrats are so fond of China is that they wish they could still get away with forcing slaves to pick cotton.

Jam Jam Jam Jam Jam…

After the refreshing take on the SAO universe that was the Gun Gale Online anime, I took a look at the translated light novels, which are currently up to 7, and it’s the same thing over and over. Squad Jam, Squad Jam 2, Squad Jam 3, Squad Jam 4, Squad Jam Party, Squad Jam Sausage and Jam, etc. I think I’ll pass.

10,000 channels, still nothing on

I don’t miss DirecTV, especially since I hadn’t watched anything on it for several months before canceling. I also haven’t watched anything on Hulu, dLibrary Japan, BritBox, or STARZ. Also very little on HiDive, Crunchyroll, or Funimation.

Which leaves Netflix and Amazon Prime Video, where I spend more time scrolling through listings than actually watching anything. Most recently I’ve rewatched an Indiana Jones movie, some of my favorite SG-1 episodes, and the first half of several movies from the Seventies and Eighties.

Last night, after N minutes of deliberation, I watched the “dinner with Dad” scenes from episode 6 of the second season of Umbrella Academy.

Speaking of which, I understand they’re scheduled to start filming season three in February, but I haven’t seen anything about them hiring a new actress to play Vanya. Surely they won’t let a man steal that role from a woman.

Cognitive Dissidents

With the looming threat of a brief Biden presidency, and the only-slightly-less-imminent threat of a Harris presidency, there’s another problem with those N million citizens who were so inspired by Biden’s vision for the future that they put him over the top: the Democrats are an incredibly racist, sexist party.

After all, none of these people were willing to vote for Obama or Clinton. Only the promise of a rich old white man could get them to the polls for the very first time in their lives.

Or else they don’t exist, and will disappear as swiftly and silently as they appeared, a mystery never to be explored by the media.
