Well I mean, technically that’s not incorrect: drink enough of it and it will kill anything, including you.
- Comment on The Return of the Pebble Smartwatch Is a Sign People Crave Something Unique 1 week ago:
Exactly.
People don’t root for feature-poor stuff because it’s unique but because the features it’s missing - that you want - preclude the hardware and the hardware maker from slipping in features that you don’t want.

- Comment on The Return of the Pebble Smartwatch Is a Sign People Crave Something Unique 1 week ago:
I think it’s also a sign that people want a device that doesn’t come from Big Data, isn’t online and isn’t designed to put them under surveillance and invade their privacy.
- Comment on Donald Trump's approval rating collapses with rural Americans 1 week ago:
But… Trump is the archetypical New York slick rural America surely despise. So what gives?
- Comment on Donald Trump's approval rating collapses with rural Americans 1 week ago:
Yeah, the “hold my beer” theory of voter reaction. I get it. What I don’t understand is, even if I desperately wanted to do the inverse of what annoying dems wanted me to do, I wouldn’t be ready to objectively hurt myself and my family just to piss them off.
- Comment on Donald Trump's approval rating collapses with rural Americans 1 week ago:
Rural voters have long been a cornerstone of Trump’s base
I’ve never understood that. Why would honest, hard-working Americans root for a convicted criminal billionaire? It seems like the very definition of self-harm to me.

Finished print 🙂
- Comment on Prusa XL cam 1 week ago:
the frame rate is ass
Well, in my case, I just bolted an el-cheapo supermarket-bought webcam inside the printer’s enclosure. It’s terrible in every way: it has fixed focus and the bed of the printer isn’t in the focus plane, it has terrible rolling shutter and no manual exposure control.
The webcam is connected to one of the production servers nearby that serves up the video as a MJPEG stream using Motion. It’s Motion that limits the framerate to 2 fps, and I configured it that way on purpose: I just need the camera to know whether something terrible has happened to the print and I should stop it remotely - like parts lifting or coming fully unstuck from the sheet, extruder collision… I don’t need quality video for that, so I chose the low framerate and poor resolution primarily to save bandwidth on my home internet, which is kind of crap because I live deep in the forest 🙂
I’m much more interested in whatever mechanical contrivance you’re printing parts for, there.
It’s a bit complicated to explain, but to make it simple: the top parts are optical couplers. They have a slot and a dovetailed circular rail inside that you can’t see because it’s buried in the support. The bottom parts are shutters that ride into the rail and block off more or less of the light in the coupler that has the rail, and have a lever on the other side. The side parts are just mounting clips to hold the couplers on the optical measurement instruments they’re meant to be mounted on.
Those parts cost cents to make and work just as good as multi-hundred dollar professional optical attenuators, and they’re a lot more convenient for a quick manual adjustment that doesn’t require a precise number of decibels of attenuation.

- Comment on Bed slinger vs coreXY 3D printer 2 weeks ago:
So far our (new) machine is performing well. We’ll see how it fares in the long run. That’s one of the advantages of having my company purchase it: it’s getting a beating for work purposes, so I can test it properly before buying one for myself 🙂
- Comment on Shein Hikes Prices by Up to 377% Thanks to Trump’s Tariffs War 2 weeks ago:
In fairness, Shein and Temu can fuck right off. When the raise prices 377%, they make the worst shit China has to offer more expensive, and that’s a good thing.
- Comment on Bed slinger vs coreXY 3D printer 2 weeks ago:
I think the pros/cons come down to what you need a printer for. If you print mostly flat things, a bedslinger is fine. If you print large parts with sketchy bed attachments like I often do, a coreXY makes a lot more sense. You have no idea the amount of filament I wasted on giant brims and rafts to keep parts from flying off the sheet - not to mention the time it takes to print them.
And then of course, the Prusa XL in particular can be outfitted with up to 5 separate extruders. It has nothing to do with coreXY but it was a big part of why we bought it.
- Comment on Bed slinger vs coreXY 3D printer 2 weeks ago:
I haven’t tried pushing the speed yet. I’ve been playing with multi-color and multi-material prints, as well as long tall thin prints that were kind of impossible on the Mk4. And when I’m not playing with that, I’m running it almost 24/7 because I have to produce sets of parts for our production floors asap and it takes about 20 hours for each set.
But soon the machine will be more available and I’ll play with it some more.
- Comment on Bed slinger vs coreXY 3D printer 2 weeks ago:
That’s true. The Prusa XL is larger than our Prusa Mk4 with the enclosure, but still fairly comparable. But the XL’s build volume is kind of… staggering in comparison.
- Comment on Bed slinger vs coreXY 3D printer 2 weeks ago:
The Prusa XL doesn’t lack rigidity. That thing is build like a tank. It feels a lot sturdier than the Prusa Mk4.
Then again, I guess they’re not in the same category… - Comment on Bed slinger vs coreXY 3D printer 2 weeks ago:
With those flat plates I’m printing, there’s zero difference. But when I have to print tall thin things, like for example a long tube to adapt diameters, it’s doable without any support on the XL, while I need a gigantic raft and glue on the Mk4 - and even then, it shakes enough that the diameter is not that great at the top.
Also, the XL has two heads, so I can print TPU with PLA support.
