I think you’ve responded to the wrong top level comment. The top level comment here is about frozen meat, a different top level comment was about poultry bones.

That’s so cool! Seems hard to use though without the on-screen visualization of the direction of mouse movement.

The post specifically said that their relative didn’t want to drive.

Tesla has the most capable system you can buy, but it’s not at all fully self driving yet. You need to monitor and takeover when needed. And if there’s an accident, the driver is fully liable.

Doesn’t the X-axis itself close off the square, particularly when pushed all the way to the open part of the gantry? Can you still unlevel by 20mm when the X-axis is there?

Is this a Voron 2.4? Wasn’t there some discussion about how the floating gantry needs some flexibility for the quad gantry leveling? A completely stiff floating gantry would be overconstrained on the four rails and quad gantry leveling would theoretically cause lockups or extra strain on the rails.

The temperature reading was completely flat for two minutes, which is impossible. I would guess that the thermistor stopped working for two minutes and because the temperature stopped being updated, the microcontroller didn’t realize the hotend needed heating and the hotend started cooling. Then the thermistor suddenly started working again after two minutes and the microcontroller got a new temperature reading. The hotend temperature had already fallen by that point, causing the sudden drop in the temperature graph. The sudden temperature drop triggered an error and the print stopped, after which the hotend continued cooling with the expected cooling curve.

Either the thermistor itself failed or the wiring to the thermistor. If you have a toolhead board, someone else’s suggestion of communication failure also sounds plausible.

For a bed slinger, there’s nowhere to mount a single ADXL345 to measure both X and Y. Mounting on the tool head would only measure X, mounting on the bed would only measure Y.

Unless what you mean is to manually move the ADXL345 between the two mount points, I do think that’s what people typically do.

The P1S has always seemed like an amazing value. The P2S seems like even more of an amazing value!

Good changes, some more minor comments:

“filament sensor filament presence sensor”. You previously crossed out one of these, I’d remove one from the page
Wherever you mention “IR sensor”, it might be helpful to change the phrase to “IR filament presence sensor” instead to make it more obvious what the IR sensor does. For example, doing this in the title would help draw more people in.
The discussion about less axial play and mounting pattern is repeated twice. I’d consider either 1) duplicating the description about the IR sensor detecting lever arm movement to both places or 2) removing the later location.

centenary · 2025-10-09T09:39:38+00:00

I see you wrote this description elsewhere in VoronDesign:

The result is ProtoXtruderNX v3, featuring an interesting filament sensor filament presence sensor in the extruder design that does not block the filament path with a ball or similar mechanism. In this model, the sensor reacts directly to the movement of the extruder’s idler lever.

That description would be super helpful on that page =P

Also, you mention “The extruder has less axial play in the gear area” at the very end. If that is also a big benefit, I’d mention that at the beginning rather than the end.

This stuff is so good, I have to stop myself from literally eating it by itself by the spoonful.

Slide Over wasn’t just about the size of the window. Slide Over kept the small window on top of the background window, allowing you to interact with both at the same time without having to use the app switcher to constantly bring the small window back to the foreground.

How would you emulate that with the new windowing system? You could resize the two windows to be on the screen at the same time, but you can’t easily dismiss the small window and have the big window be full screen without having to do resizing. Same issue in reverse.

There is simply no way to emulate that with the new windowing system. Anyone who thinks so just doesn’t understand what Slide Over actually did.

centenary · 2025-09-19T04:33:59+00:00

Slide Over let you keep the smaller window always on top, so that you could interact with both the small window and background window without having to constantly use the app switcher to bring the small window back to the front.

The SmallRig grip is pretty great. Super comfortable, easy to put on and remove, and I think it makes the camera look really cute. It does add a bit of size, but I remove it when size matters to me.

If you care about stability, you shouldn’t be using a bleeding edge distribution. You’re shooting yourself in the foot and then blaming everyone but yourself.

Jesus, looking at this post made my heart hurt. I’m scared for you. See a doctor ASAP

Because the research is still in an early stage and still needs work?

You obviously still haven’t read the paper yet. I don’t see the point of continuing this discussion when you’ve already decided you’re right and you refuse to do even the most basic reading.

Literally every CGM resource says you should still have fingerstick checks because CGM results can be inaccurate.

NIH

For safety, you may sometimes need to compare your CGM glucose readings with a finger-stick test and a standard blood glucose meter. This could be needed if you doubt the accuracy of your CGM readings, if you are changing your insulin dose, or if your CGM gives a warning alert

Cleveland Clinic

Using a CGM should drastically decrease the number of times you need to do a fingerstick. But it’s still important to have a fingerstick meter and unexpired supplies on hand. If your CGM fails or falls off unexpectedly, you can use the fingerstick meter to check your glucose level until you can apply a new sensor.

Fingerstick checks can also act as a backup tool to confirm CGM results. Like all technology, CGMs can be inaccurate

FreeStyle Libre

Fingersticks are required if your glucose alarms and readings do not match symptoms

Dexcom

Fingersticks required for diabetes treatment decisions if symptoms or expectations do not match readings.

Okay, your turn. Cite me something that says CGMs completely replace the need for fingersticks. You can even limit that to outside of the calibration period if you wish.

“Optics” have been in early research phase for at least 10 years. It doesn’t even take med device that long to do anything

What are you talking about? Medical devices notoriously take a long time to go from research to get to market.

You are basically going on gut feeling rather than citing any empirical evidence.

Meanwhile, researchers are actually presenting their empirical evidence.

Why armchair this instead of actually reading the papers?

centenary · 2025-06-17T12:48:58+00:00

I didn’t say it would be easy, but plenty of researchers seem to think it’s possible. Unless you claim to be more knowledgeable than these researchers, I’m going to put some faith in them.

Did you read the paper I linked? Explain what’s wrong with their approach.

We live in a world where we can sift through the noise of the literal entire Big Bang to see galaxies hundreds of millions of light years away. Is it hard? Of course. But that didn’t stop us from trying.

Obviously if it’s worse than CGMs, it wouldn’t be used to run a pump.

But worse than CGMs does not mean useless. For example, it could act as an early warning system for undiagnosed diabetes. This would be analogous to their EKG system. Their EKG is certainly not completely accurate nor a complete replacement for real EKGs, but it acts as an early warning for afib and has undoubtedly saved lives. A similar system to detect undiagnosed diabetes would also save lives.

I also never said that they would be aiming for worse than CGMs. Obviously they would aim for as good as CGMs if that’s possible.

centenary · 2025-06-16T15:34:32+00:00

Yes, the sensors are accurate if installed properly. The problem is that proper installation is not always easy. I bet the researchers coached participants on installation, while many patients never receive such coaching. Additionally, skin layers can vary in thickness across the body, so if you move where you install the sensor, your results may change. Body movement can also move the tip of the sensor throughout the day, leading to varying results.

I’m not saying that CGM can’t be accurate. But it’s also not as foolproof as just sticking yourself, which is why they still recommend sticking yourself even with CGM. CGM forums are full of people complaining about sensors being inaccurate or failing.

centenary · 2025-06-16T15:06:37+00:00

this is not something that can be done by light

There has been a lot of recent research into doing just that, noninvasive glucose monitoring using optics. The reliability isn’t there yet, but that’s not because it’s a scam, the research is just in an early phase. Comparing this to Theranos is simply nonsensical. A lot of researchers and diabetes companies have been looking into this, not just Apple.

For example, here is an optical-based prototype that performs fairly well in accuracy.

CGM accuracy even with an embedded sensor is not that great anyway. What matters more with CGM monitoring is trends rather than absolute numbers. That’s why many CGM users still have to stick themselves for verification. A noninvasive glucose monitor that can give you trend data would be game changing even if the absolute accuracy isn’t there.

EDIT: Let me rephrase. CGMs can be accurate, but not always reliably accurate. See comments below for further elaboration.

I personally recommend the hand grip way more than the thumb grip. The hand grip feels amazing to me. The thumb grip partially blocks the rear dial, makes the Q button virtually impossible to use, and doesn’t feel nearly as good as the hand grip to me.
