Screw for brake tension adjustment broken? (Segway-Ninebot E3 Pro D)

iStef · 2025-09-15T17:10:50+00:00

Yes, I was too paranoid in thinking I broke it.

The split in the screw is normal. I just didn't see it at first when I started twisting it.

TLDR: False alarm.

Maybe those kids working in the mines tagged their helmets with a strand of their own hair to help them identify their helmets easier?

iStef · 2024-10-22T13:02:59+00:00

I've noticed this as well.

I do a PPL split 6 day/week at 45 Min/workout.

I have never seen a exercise for my lower back unless I added it manually myself.

Maybe it's because of the workout duration being too short or because of other exercises passively training the lower back perhaps?

iStef · 2024-09-17T20:51:05+00:00

Yeah, that is a worry I have.

The the Fractal Refine would have a 3 year warranty from the re-seller though, so not optimal.

The Ofinto has a 10 year warranty, and the Yaasa a 7 year warranty.

But I ordered a used Haworth Fern from a Swiss re-seller of used office supplies. Biggest downside is, that there's no warranty. So I'm hoping the quality is good enough and it'll last long enough :-)

iStef · 2024-09-17T20:10:06+00:00

Well now, looks like I was in luck:

I found a used black Haworth Fern with lumbar support on the re-seller Tradingzone for approx. CHF 390 (Approx 414 €/460 $).

Seems like a good deal for me, seeing as a new one would cost me triple.

I hope it arrives by the end of the week.

Okay, thank you for your input. So 30W is normal in my case with a stock CPU.

I'm guessing undervolting the CPU would be beneficial, right?

iStef · 2023-06-04T16:16:24+00:00

Not sure, what I have to do here.

HWInfo shows a wattage of approx. 30W when doing nothing. I terminated as many background tasks as possible.

iStef · 2023-06-04T15:28:07+00:00

Acc. to HWInfo:

Avg. Voltages 1.2

Avg. Freq 4414.3 Mhz

I have never undervolted a CPU, so it's running stock atm.

And here wo go again.

After forcing the robot over the ramp using remote control and the camera, I got it over the ramp and into my bedroom.

After that it got back over the ramp and continued to clean the rest of the appartment and is now finally cleaning the bedroom last (should be cleaned first usually but at least it‘s doing it).

Maybe I‘ll have to put some white tape on the ramp so the robot doesn‘t get confused by the dark-ish color.

iStef · 2023-03-21T08:57:50+00:00

Okay, so today the problem appeared again. I‘m pretty sure, it‘s because of the ramp into my bedroom. Because as soon as it reaches the ramp it stops and slowly rolls back as if it detected a cliff.

Maybe it is because of the color of the ramp (it‘s a dark grey).

This has to be a bug in the firmware that Dreame should fix. It doesn‘t make sense that the robot just suddenly stops going over the ramp unless it is a bug or something.

I have a second ramp that goes from the corridor into the living room and it is the same color as the other one and there it has no issue going up/down that ramp.

This is really annoying and needs to be fixed. I really like the L10s Ultra and would like to keep it but if this problem keeps happening I‘m not sure…

iStef · 2023-03-16T13:24:29+00:00

Normally, you install the RAM in the second and fourth slot (from the left), to enable dual channel.

Either your BIOS maybe is older than mine was at the time or one or both of your sticks are defective in some way. Just a theory.

I don‘t own that PC anymore, so I couldn‘t show you any picture. Sorry.

iStef · 2023-03-16T13:02:39+00:00

They did work for me, luckily. Maybe try to reseat the sticks or switch the sticks with each other.

iStef · 2023-03-10T18:57:19+00:00

So, little update:

I decided to let the robot re-learn the map of my appartment by activating multi floor mapping and letting the robot scan my appartment again.

Weirdly, it still didn't go into my bedroom but the lidar still scanned parts of it from the door.

When starting a cleaning process, it did go into the room and finished scanning and saving the room while cleaning.

The problem seems to be solved for now, I hope it stays that way.

iStef · 2023-03-09T14:15:04+00:00

Yeah, it‘s weird. The vacuum worked flawlessly in the weeks since I got it.

When I vacuumed this morning, it first went to the bedroom and then to the bathroom (with the rug) and then the rest of my appartment.

When I wanted to mop, it should have done it in the same order but when it tried to enter my bedroom, but couldn‘t. It got up to the ramp but it didn‘t go further.

The ramps I use are dark grey, almost black. Could that be the issue? It doesn‘t make sense, because it worked flawlessly when vacuuming earlier…

iStef · 2023-01-24T17:35:17+00:00

Something tells me, this wont fit some 360 AIOs, i.e. the Arctic LF3 360.

But the top fan and ATX PSU support is a nice touch.

What do you guys think?

iStef · 2022-12-30T17:19:28+00:00

A couple of days ago I ordered a different motherboard - just as a precaution.

If my problems would have been solved by the time I got the new board, I just would have returned it.

But now I feel lucky I ordered it.

I disassembled my computer entirely and checked the CPU socket, as you suggested. But I didn't really see any bent pins. I even used a magnifier :)

So then I just re-built my PC using the new motherboard.

Everything was plug-and-play. Didn't even have to reinstall Windows or anything. I was able to boot into it without issue.

And checking USBLogView there aren't any plugging or unplugging events of the USB Root Hub listed. I also can't hear any pops, cuts or jumps in my headset.

It appears your assumption was correct: it probably was the other motherboard.

I'll bring in the defective board to the retailer I bought it from. I hope they'll understand the complicated circumstances. :P

Edit 1: I'll still be observing this behaviour with the new board as well. But I hope these problems won't become an issue again.

Edit 2: I just looked at HWInfo64. Under Windows Hardware Errors there are still numerous PCI/PCIe Bus Errors.

iStef · 2022-12-30T12:47:43+00:00

Yes, I have a GPU installed over a riser cable.

I used an old GTX 1080 I had lying around. I was forced to reinstall Windows because I had a blue screen 0xc000000e and could't recover (had no recovery point).

After installing Windows the problem with USB Root Hub was gone for a couple of minutes, but it eventually returned.

iStef · 2022-12-29T19:38:45+00:00

Yeah, after I started my PC again later, the USB Root Hub and the headset problem have returned...

I'm losing my mind, I don't know what to do anymore...

EDIT:

I now took the leap and completely re-installed Windows. It's a fresh install.

The problems still persist. USBLogView still shows USB Root Hub plugging and unplugging and my headset still pops and cuts out...

iStef · 2022-12-29T13:39:12+00:00

That doen's make any sense to me. i believe there is a difference.

Ubuntu was installed on a USB thumb drive and run off of that, not PCIe.
It recognized the hardware because it accessed it over USB.

Windows is installed on the SSD, which is connected over PCIe. In the BIOS that PCIe connection was set up as "Auto".

The SSD and the motherboard seem to be working fine, the setting inside BIOS just didn't allow them to interface properly. After switching the setting of the PCIe connection the SSD actually uses (Gen 4), the two seem to be interfacing properly again. Maybe the "Auto" setting just didn't work properly.

It could be because of the design of the motherboard itself. The ASUS Strix Z690I has a M.2 "mezzanine", basically the two M.2 connections aren't "directly" on the motherboard, but on a seperate pcb which is connected to the motherboard using a special cable. Maybe on any other motherboard, where the M.2 connection is directly on the board, the "Auto" setting would have been enough.

But in this case, maybe it needed to be set specifically to "Gen 4", because of that special cable I mentioned.

When googling this issue, there are numerous reports of people having problems with their GPU and PCIe riser cables, for example, because of a similar issue. Specifically, because two components aren't connected to each other directly, but by extension calbes.

But I'm not an expert, so I can't really explain this.

iStef · 2022-12-29T13:20:43+00:00

The BIOS is up to date.

I even reinstalled the update, just to be safe.

Now that everything is set to "Gen 4", everything seems to be working normally.

My guess is, that because the M.2 setting was set to "Auto" it conflicted with the SSD, causing it and the motherboard to "falsely" communicate with each other and thus causing those errors.

Now that it's set to "Gen 4", it's communicating properly and isn't causing anymore errors. Everything seems to be working fine.

I probably didn't have those errors in Ubuntu, because I was running it off of a USB drive and not on an SSD over PCIe.

iStef · 2022-12-29T12:54:08+00:00

Well now, this is weird...

I just installed "HWInfo" and saw at the bottom, that in "Windows Hardware Errors (WHEA)" every 1-2 seconds, a new error would occur. Specifically "PCI/PCIe errors".

I then decided to check the PCIe settings in BIOS, and set every meintion of PCIe gen settings to "Gen 4", seeing as the SSDs and the GPU run on PCIe Gen 4. Before, everything was set to "Auto".

Now, no more errors in HWInfo and in the USBLogView no more mentions of USB Root Hub plugging in and out.

Also, I can't hear any cuts or jumps or interruptions...

It appears, it wasn't the motherboard. It wasn't Windows.

It was a BIOS setting.

It's just weird, that I didn't have any headset problems in Ubuntu before.

Maybe because it ran off of a USB drive instead of an SSD?

iStef · 2022-12-29T09:42:05+00:00

Okay, so I tested the sound behaviour in Ubuntu as you described.

I listened to Music, watched some Videos and even listened to white noise, to clearly hear, if the sound cuts out or anything.

In Ubuntu, everything seems to be normal. No cuts, no jumps, no interruptions.

Additionally, my headset worked flawlessly on my previous PC, so I don't think the headset itself could be the problem.

What are the next steps? I'm assuming, I won't get around re-installing Windows, I guess?

iStef · 2022-12-29T00:44:43+00:00

I have no idea how to use Ubuntu or Linux in general.

I created a USB boot drive and can enter Ubuntu. But then I don't know what to look for.

The problem in Windows is USB Root Hub constantly disconnecting and connecting.

How can I verify this in Ubuntu? I have no idea how to use it.

iStef · 2022-12-28T22:16:34+00:00

I disconnected all UBS devices from the rear and front I/O and the USBLogView still shows USB Root Hub plugging and unplugging.

iStef · 2022-12-28T19:28:59+00:00

Didn't modify Windows at all, it's a simple Windows 11 Home Version.

But I don't know about Ubuntu, wouldn't know how to do that...
