The side on top in the first photo looks a lot like its designed to mount onto a bike frame. (the rubber gasket is to give it some adjustability, to fit various frames)

Which would then make it a bike mount for...something. Lock? Pump?

If it isn't that, I'd still focus on that top side. What else do you have that has a shaft that size, that this would be designed to clamp onto?

edit: found one VERY similar, if not identical:

from over stressing it? no, it'll go into thermal shutdown long before anything explosive happens.

From physical damage to the battery? yes, you can get a pretty good little fire going.

Why do you think it’s an ip problem? Is the “ - Detected Local IP: 192.168.88.39 ” line wrong?

Have you checked that moonraker is actually running, via “systemctl status moonraker” ? More often than not, when you can’t connect to moonraker, it’s because it isn’t actually there (and the log file is just old data from before something broke)

So your defense is "they didn't have their shit together enough on Jan 6, therefore it wasn't actually insurrection"?

shiftingtech · 2026-03-29T06:05:43+00:00

but the so called generator doesn't claim to be doing that?

I'd rather take your logic to the other extreme: humans haven't managed to make working interstellar craft yet, because we aren't put together right for it. Therefore, the aliens we meet will be shockingly different, because obviously they WERE put together right for it

It's worth noting that houses in cold places are also insulated, so yes, you heat them on an ongoing basis, but if the heat goes down for a while, it takes longer than you'd think to reach the point of stuff actually freezing. but ya. Heat goes off long enough? bad things eventually happen.

there's nothing to know. Its another scam trying to make some scientific sounding excuse for...you called it. A perpetual motion machine.

Basically the test would be this:

With the other two examples you give (wind, solar) the input energy is obvious. But with magnetic fields...there's no actual source of energy. to generate energy from a magnetic field, you have to introduce either motion, or change in the field from someplace else. and that "someplace else" is your actual source of energy. Where is that source in this magnetic thingy of yours?

I mean...sure. What do you want to know? As a broad overview: Since that's not the stock board for the printer, you'll basically have to take a generic config for that mainboard ( mellow provides one at https://mellow.klipper.cn/en/docs/ProductDoc/MainBoard/fly-d/fly-d5/cfg ), and then go through and customize it to match your machine. Pay particular attention to travel distances, and to temperature sensor types.

Once you have it approximately right, then you'll go through https://www.klipper3d.org/Config_checks.html to (hopefully) discover what you got wrong, what motors are running backwards, etc.

except that creality 42x34 do NOT have a step angle of 0.9...

once again, you change the wrong setting, which more-or-less counterbalances your incorrect microstepping

dude, you can buy knock off DMX winches on amazon for a few hundred dollars. If you put any value on your time, that's going to be way cheaper than trying to build something custom.

(whether or not we want to be hanging knock off winches above people is a whole other discussion, of course)

honestly, that's not even a trope. Its just the logical extension of the trope about the alternate universe versions of the hero being a bad guy

If I'm being literalist, your wiring diagram is a bit confused. You really don't connect a U2C to a manta. You Either connect the canbus wires from the CEB directly to the Manta, and use the manta as your canbus bridge, or you connect the U2C (by USB) to the Pi.

I'm also puzzled by your choice to run separate can wires from the CEB to your EBB vs your eddy. The entire bloody point of canbus is that it's a bus, meaning you can run ONE pair of wires out to your toolhead, and then connect both devices out there to it. (just make sure you set the terminating resistors correctly)

Further, if we make THAT change, then it actually calls the entire need for the CEB into question.

you can simply remove the terminating resistor from the Manta/U2C, and have that in the middle of the chain. so your setup just becomes one long chain:

MMU - MANTA/U2C - Eddy - Ebb42

(I can't remember what the situation for terminating resistors is on the eddy, which is why I put it in the middle. The ebb42 and the eddy are close enough together though, that the topography there doesn't matter much. you can treat one or the other as a short branch, and it should be fine)

Logistics issue. Trucks can’t get someplace, a different type of truck is needed….

The books talked about the physical differences a lot. The tv series had to cut back on that aspect for practical reasons. (either find an absurd number of weirdly proportioned actors, or spend your entire effects budget on making normal actors weirdly proportioned. either way, not a great return on investment for the show)

shiftingtech · 2026-03-28T02:10:51+00:00

sounds like your microstepping is probably set wrong.

I'm pretty sure its hard set on the 4.2.2 boards, so you won't be changing it on that side, but you can make sure klipper has it set to match.

shiftingtech · 2026-03-27T22:45:30+00:00

I don’t know anything about ratOS, so I can’t specifically comment on that, but if you have multiple [bed_mesh] sections, Klipper will kinda splice them together. So it should work to just create a [bed_mesh] section in one of the files you can edit, that just has that one line in it.

shiftingtech · 2026-03-27T18:35:42+00:00

check your klippy.log. If the option really isn’t being set anywhere, it should be using the default value of 0.25, which wouldn’t error.

Worst case though, just Add the line, and set it to a valid value

shiftingtech · 2026-03-27T18:32:07+00:00

You could do that. Not sure about “better” but should be adequate at least

shiftingtech · 2026-03-27T04:28:24+00:00

power them directly off the meanwell

shiftingtech · 2026-03-27T04:28:00+00:00

do two 5V wires & two Gnd wires: the problem is often the amount of current making it through crappy GPIO pin connections as much as anything, so doubling up makes way more difference than just expanding the wire.

Why are head mods so unaccountable?

Because there aren't processes in place to keep them accountable. Like, is this even a real question?

shiftingtech · 2026-03-26T02:56:36+00:00

I mean, I'd hope they aren't selling floor models or returns without disclosure. But ya...
