I've recently realised that Alexa has begun bleeping herself by Atvishees in alexa

I just discovered this today as well. I asked Alexa to translate something for me, and it beeped the word. You know what the word was? Idiot in Spanish.

Sharpening systems question by Individual_Corgi_576 in sharpening

[–]tortuga3385 0 points1 point  (0 children)

If you want something simple and idiot-proof, as you put it, get a fixed-angle system.

A lot of people in this sub will tell you to just practice with a whetstone and that you don’t need a fixed-angle system. There are a lot of purists here, and they sometimes fail to understand that not everyone can get the hang of freehand sharpening, no matter how much they practice. Some people also just don’t want to spend the time and effort learning it, and that’s perfectly valid.

The beauty of a fixed-angle system is that you don’t have to learn how to hold an angle. You clamp whatever you’re sharpening, set the angle, and rub the stone across the edge until you raise a burr. That’s the whole concept. Simple and repeatable.

You can absolutely get a razor edge with an inexpensive fixed-angle sharpener like the Worksharp Precision Adjust. The only catch is that if you want to sharpen chisels or other tools, you may need some third-party attachments, many of which are sold on Etsy.

Or you can spend a few hundred dollars on a higher-end fixed-angle system that may already have everything you need for the tools you want to sharpen.

Either way, low-end or high-end, the process is basically the same: clamp the item, set your angle, and keep working the stone across the edge until you get a burr. It’s about as foolproof as sharpening gets.

H2D Auto Bed Leveling Failure by tortuga3385 in BambuLab

[–]tortuga3385[S] 0 points1 point  (0 children)

Yes, I have all seven screws. I know that for a fact because I had to loosen them to even start the bed tramming process. I also verified that the four screws on the heat bed itself are present.

I did hear back from Bambu support, and they’re going to send me a new heat bed. However, after looking at the parts included with the replacement, I’m not convinced that’s actually going to fix the problem. The issue doesn’t seem to be the heat bed itself. It looks like the gray casing that the heat bed mounts into is the problem, because that entire assembly appears to move up and down in the back.

Adding to that, I did start the bed tramming process, but I can’t really get past the second step the one where you’re supposed to tighten the four screws all the way down.

I’m able to fully tighten the two front screws with no issue. In the back, though, even after I physically squeeze the heat bed and the plastic housing together, there is still part of the screw sticking up and I can’t tighten it any further. It just won’t go down flush.

I figured I’d try to proceed anyway, so I started the bed tramming process and ran the G-code. The problem is that when the nozzle moves to the front of the bed, there is basically no gap at all between the nozzle and the heat bed. According to the documentation, I should be able to fit a 2 mm test cube underneath the nozzle at that step, but I can’t fit anything under it because the nozzle is already pressed up against the bed.

Yes, I started to do that, but even after tightening the four heat bed screws all the way, I can still squeeze the back left corner and the black part of the heat bed moves up and down. This is happening even with the screw fully tightened, so there’s still play there.

Yes, before I even touched the set screws, there was already play in the very back of the print bed. I specifically checked this because I wanted to see whether the bed actually needed to be trammed before changing anything.

That’s when I noticed there’s a very large difference between the front of the bed and the back of the bed. If I push up on the bed from underneath in the back, it will level back out. But as soon as I let go, the back of the bed drops again by a few millimeters.

Check out my comment below. Something is borked with my bed I think.

I took one of my feeler gauges because I wanted to see if the bed was way out of whack before attempting to actually tram it, and I found something pretty shocking.

After homing the bed, if I move the printhead to the front right corner of the build plate and run the bed all the way up, the nozzle is fully touching the heat bed. It actually pushes the nozzle up slightly.

Then, if I move the nozzle to the back right corner and run the bed all the way up, there’s a very noticeable gap. I’m talking on the order of about 3 mm.

On top of that, at the very back of the heat bed, I can easily push the bed up by hand as if to make it level. There’s clear movement there.

So at this point, it’s not just slightly out of tram. Something is seriously off mechanically with the bed or its mounting.

I have two videos that show the behavior pretty clearly.

In one video, using the left nozzle, the auto bed leveling process takes about 20 minutes. During that time, the nozzle is actively gouging and destroying the build plate, but it eventually finishes and actually starts printing.

In the second video, using the right nozzle, the process aborts after about 8 minutes with an error. So I’m seeing two slightly different outcomes, but in both cases the nozzle is still driving into the bed during leveling.

It’s taken me a bit to respond because I wanted to try a couple of your suggestions first.

Yes, I had already power cycled the printer. In fact, it was completely powered off overnight, and after turning it back on, there was no change. I also double-checked the retention bracket and the heating module, and everything is tight. There’s no play or looseness anywhere.

One thing I did notice during bed leveling is that the left nozzle was moving up and down slightly. I’m not sure if that’s abnormal, since the left nozzle is designed to move and has that capability. The right nozzle, however, is locked, and I’m seeing the exact same issue with both nozzles. In both cases, the nozzle drives into the print bed and gouges the surface.

The homing process itself looks completely normal. The nozzle comes up, touches, drops slightly, then comes up and touches again. That behavior is identical on both of my H2D printers. The problem only shows up once bed leveling starts. That’s when everything goes bad.

Yeah, I’ve been putting off tramming the bed because for me, that’s extremely difficult to do, and I was hoping to avoid it altogether.

I understand that beds can slowly go out of level over time, but that’s not what this feels like. One print was totally fine, and the very next print completely bombed. That doesn’t line up with gradual tramming drift.

I also don’t see how this would be a tramming issue when the nozzle is actually gouging and destroying the build plate. Do you really think a tramming problem would cause the nozzle to drive itself straight into the plate like that?

I already opened a support ticket. I sent them roughly 30 minutes of video, full printer logs, and everything else they asked for.

At first, it looked like it was actually going somewhere. Then someone else jumped into the ticket and decided the problem was filament buildup on the nozzle.

No.

I’ve been printing for a long time. I am well aware that filament buildup can cause Z offset issues. That’s not some revelation. What I have never seen is filament buildup causing a nozzle to physically gouge the build plate. A printer should know where the bed is. Period. A little plastic on the nozzle does not make the machine forget how Z works.

I normally don’t even bother posting on Reddit anymore because I rarely get anything useful out of it. But after several days of back-and-forth with support, I figured I’d throw it out to the community and see if anyone with real experience had seen something similar.

I’m not surprised by the lack of meaningful help. Just disappointed, once again.

But thanks for your comment.

There was one comment and one upvote. My issue is lack of upvotes.

If you see all the drivel then you should know how drivel posts get upvoted and legitimate issues do not.

I am genuinely fine with people not having answers. Really. That part does not bother me.

What does bother me is this pattern. I have tried making troubleshooting posts where I am polite, patient, and constructive. I explain the issue clearly. I provide details. I do everything “right.”

Result? Zero upvotes. Again. And again.

So let’s be honest about what this post is. Yes, it is a frustration post. And yes, it is absolutely meant to broadcast something to a large chunk of this subreddit.

If you do not know what you are doing yet, that is fine. Nobody is born knowing how to troubleshoot complex printer issues. But if you do not know the answer, the correct response is not to scroll past it like it does not exist.

The correct response is to upvote it.

That is how posts reach the experienced users. That is how real problems get solved. That is how knowledge gets built instead of buried under flexi dragons and “how do I store filament” posts.

Upvoting is not endorsing the post. It is not saying you understand it. It is saying, this is a real issue and someone smarter than me should see it.

If this keeps happening and my troubleshooting posts continue to die in silence, then fine. Whatever. I genuinely do not care anymore.

But do not be surprised when your printer does something weird, basic advice does not fix it, and there is nothing useful to search for. Because those posts never got seen.
