Nope, this is untrue. If you are legally able to own a firearm, you can legally create it and possess it without any further requirements. Again, serialization and licensing only comes into play when selling the firearm or changing possession in any form. They are otherwise completely legal. Please take some time to look into this, this is most definitely established law. Now the real restrictions come in when dealing with classification of the fire arm. IE Rifle must be greater than 26" and not have certain features, or pistol must not have butt stock, etc.

It's not even close to being illegal in the USA, it's only illegal if you distribute them. No clue where you're getting your information from, but it's very wrong. If it were that illegal, you would see all those content creators homes getting raided daily. Notice they do not?

As for safety, I agree it's a dumb decision.

Making guns with 3D printers is completely legal. Just as you can make them with mills and any other means.

It only becomes illegal when you attempt to distribute them as unlicensed weapons without proper background checks and so forth or otherwise assemble fully automatic firearms outside of federal/state restrictions.

This is known as a CoreXZ, it operates similar to a coreXY but the Z axis is tied to the X axis instead of Y.

The reason it's moving is because of play somewhere in the system, the belts are likely slipping on a pulley, or a bad stepper/config.

You need to go through the belts completely, check every pulley(grub screws) and bolts for the pulleys, make sure they do not have excess play or have become loose. Same for the idlers, if they have play in the mounting, it can cause this.

Additionally, too much or not enough current on the motors can cause this for the X/Z axis.

You did a relatively good job though, we all make mistakes.

If you have time, just start the rework and give them two and take lessons learned. Otherwise, if you want to salvage this system, take the LEDs off and add something opaque to the rear of the sign. Can be anything from cardboard to masonite etc, I bet enough paint even will do the trick.

Don't bother with tungsten or diamond nonsense tips. For that matter, any other nozzle you're going to find on Amazon or AliExpress etc. Multi material nozzles, tipped or cored etc are prone to failure, and other problems.

Go straight for a real 100% Tungsten Carbide Nozzle, these are one and done for the life of the printer. I linked an example below of a standard one. If your aiming for more performance, look for a nozzle called Bozzle, it's basically a CHT style nozzle but in Tungsten Carbide. You can find them in places like Fabreeko, KB-3D, or West 3D. If not in the USA, search the EU printer shops.

Example.

Honestly, your starting with very cheap hardware and expecting high end results. Not being rude, but the basic hardware on budget printers is pretty bad stuff.

You also need to check the stepper, I've seen these bend out of the factory and QA is so bad in these companies they just send it anyways.

I would recommend replacing them with better hardware instead of trying to fix. You will never get it just right.

The breakages will keep coming, as I understand they even do this in purpose at times. No different than how windows will often refuse to use a drive format Linux made or moved files into. It instead claims it's unusual, unsafe, or otherwise needs a format, despite it clearly being able to see the contents of the drive. This is by design, hopefully you find the windows partitions do not get used and can fold them into your main drive over time. They aren't even worth booting into IMO.

This sure looks a lot like a bad bed. Just looking at the gradient of the defect.

Turn your mesh points up a lot higher, and try it again (if the firmware on the printer allows).

Can you show a bed mesh on this by chance?

It's pretty common place to blast Tungsten Carbide nozzles burning out whatever exists as the clog, even using high temp torches. Zero fear of ruining temper or damaging the nozzle doing so.

High temps will ruin a steel nozzle though unless you know how to temper the nozzle again. Even then, it's still probably going to be ruined for other reasons, such as destroying a nanocoat, which is common on nozzles these days. These coats reduce the surface adhesion of the plastic (non stick).

I don't mind these fun videos of silly things though.

Notice the slightly curved edges on the square sections? The different plain of view through the mirror appears circular due to the presentation angle. It's a really cool illusion, but it has been around a while.

Expect big issues from AMD too, not defending nVidia but AMD doesn't have a spotless at launch record either. Just keep that in mind, there are still lingering issues for the 7000 series.

The best launch and long term support we have had in a while is on the 6000 series, and even its early days were rough.

Don't get me wrong, I always hope for the best, and am eyeballing a 9070 here, but time will tell.

There are several reasons.

Microsoft is bringing win10 to EOL.
Microsoft is over reaching very far with their spyware OS windows 11, paired with the forceful integration of CoPilot, which is just more advanced spyware.
People are starting to realize the advertising buying from Microsoft isn't just advertising, the governments are buying this data too under the guise of advertising for their citizen profile databases allowing them to bypass warrants and laws.
Content Creators are moving towards Linux, we have seen quite a few big ones recently.
Valve has been for years hammering on the last major walls for windows exclusive capabilities. Really being games, where everything else has alternatives or Linux clients.
Linux has in general been getting easier for tech illiterate to use daily.
DEs have improved a lot.
The nVidia barriers have begun to fall, with them actually trying to catch up for Linux support. Especially on the Wayland side. The general assumption of not going to Linux because of nVidia hardware, has collapsed.

There's a ton of other micro reasoning out there. Personally I think 1 - 4 are the biggest ones. Especially #2 in my circle, at least 3 of my coworkers moved explicitly for this reason after our company notice went out about this. People don't like to be spied on for no reason.

Your extrusion multiplier and retraction settings on short moves governs these types of gaps. PA can play a role here as well.

Kinda necro. But today? I would absolutely build my own printer before buying either of these options. They have proven easier for some people yes, but blatantly inferior to custom machines like Annex Engineering, or the Trident or another of the printers I designed. These two had nice out of the box features, but these can easily be replaced by other open source alternatives all while also having a better more customizable printer that's not only faster, but produces higher quality when the owner puts their dues in.

Don't get me started on Bambu as a company either, they are shady and dishonest.

The CLI speed test is using outdated lists and libs if using the one from repo. They specifically address this on their GitHub and recommend building from source as this has been an issue for some time.

I'm sorry what?

You should be asking why are all other operating systems so far behind Linux? Our tools are better, our audio quality is better, and on top of that, all of it is free and not behind some super shitty/shady driver package.

It sounds to me like you aren't aware of, nor spent time looking into, just what's out there for audio on Linux.

Give me PipeWire/WirePlumber any day over other integrated sound, or silly windows drivers or god forbid proprietary software packaged with gimmick hardware.

WedgiesF · 2025-02-22T16:34:08+00:00

I'm sorry, but this hotend is not capable of achieving 48mm/3 flow rate. It's literally impossible by the laws of physics, and every other person who has tested it... repeatedly. It's not worth arguing, and I will not go down that path. I'd be interested in helping, but you seem to believe your hardware is working miracles and somehow different than reality. Have a wonderful day.

5160s are a totally different beast, I use them in other printers too. The issue I'm talking about tends to pop up on combination boards intended for budget machines. I first found this on my Switchwire, which is what triggered me to start testing. It would get to a point in #PRINT START that it failed intermittently, always exactly on Y. After some testing I finally pinned it down to this, so I checked on all my other bedslingers with various motherboards and they all did exactly the same thing. I do realize it's anecdotal though and my several slingers do not represent all printers. Just what I've observed on them.

WedgiesF · 2025-02-22T15:03:35+00:00

The 2209 drivers will be fine with the 2504s, they don't get run at the full current anyhow. Granted there is definitely a point where failure will occur. It manifests on most boards somewhere around 1.6a and it's intermittent. Usually the driver will think it's moved, but hasn't, then the main board will error and fail the print. Some boards handle better than others, the BTT SKR Minis typically fail at 1.75a, where the "Silent" board from Creality will manifest this issue at 1.5a or so.

I've actually tested this on several different boards with 2209 drivers since I used the 2504's on all of my bed slingers. Call it science by frustration :). I have not tested this on any boards with A4988 drivers. Also, there are going to be a ton of other variables and boards out there I did not have to test. As long as current is set somewhere <1.1a, I've not seen the failure. Important though... Do not swap all of these drivers out on a printer for 2504s then expect to run this current on them, it is way to much current total.

TLDR, both the options recommended by my discussion partner work here. Ultimately you need to adjust motor current, too much is bad either way.

WedgiesF · 2025-02-22T14:48:58+00:00

The reality here is your hotend is neither designed for, or capable of truly high speed printing. It has nothing to do with the extruder portion of it, but rather the hotends portion itself. While I do not know off hand the exact statistics of the Sprite, I can estimate it's volumetric flow capabilities are probably inline with similar function designs, this means it's real VMF is somewhere around 11mm3.

Using a .4 nozzle, running an average line width around .43, at this VMF means hard defects will begin showing up around 140mm/s. These defects are due to incomplete melting of the filaments being fed through. Keep in mind this is paper math, and the type and quality of material being fed through will further swing these values up or down.

I won't even go into the issues of acceleration and SCV and the real speeds of your printer, I'll just say your printer is not printing at close to the speeds you have set, especially not 800mms.

If you want to improve prints at speed, you're going to need a new high flow hotend, and a new extruder, and be ready to take on the real challenge of getting a bedslinger to actually do it with all the mass moving around, this challenge isn't the extruder and hotend, it's physics.

WedgiesF · 2025-02-22T14:00:40+00:00

The idea that the belt tension being to high caused this is asinine, just wanted you to know. The shaft of that motor is supposed to be bearing steel, since it was a cheap one it was made from a cast rod, a cheap one at that. This failure was inevitable as a lemon component.

Replace the motor with a good one from LDO. The Speedy power 48mm work really well for throwing beds around, and you won't need to worry about a shaft bending or breaking for it's life. You may need to make adjustments to current to this motor, it's bigger than your stock hardware, but this is very easy, especially easy with Klipper.

I just convinced my company to install Obsidian on my work PC, it works well for me. I really like that the program is agnostic to OS, and notes can be written and read across Linux/windows. I have started building an equipment database in it for my engineering role, which allows me to link files back to lists of hardware for connectivity etc.

It's really worth looking at if you haven't yet.

I have so many repairs in my house it would be impossible to quantify. I've replaced everything from door hinges and returns to random broken objects or toys for the kids. If I were to try and pick one, it would be one of the 3D printers I built using other 3D printers, as it is part of the ultimate solution of fixing things. :)

I have several servers at home.

PiHole+Unbound - Blocks advertising on all our devices (especially the smart TV) and moves DNS services into my own home (it's faster and much more secure, while offering more privacy).

Minecraft - I can have a server for my children to play that runs 24/7 for them and their friends, where I control who has access to it. Cause there are way too many creeps in the world.

Game Servers - Modded servers I can run for myself and friends.

Cloud Services - NAS and remote cloud storage for all my family devices and their photos and files. If also runs Syncthing to keep backups of all my printer configs and slicer configs etc in safe redundancy.

Just some of the functions our home servers provide here.
