This seems like very standard ML. I’m not surprised it works, but also it likely takes a huge amount of training data (i.e. print samples) to recognize a specific machine.

I’ve done stuff like this. For instance I took a pre-trained model that could identify animals and used reinforcement learning to feed it thousands of annotated images of my cats. After this fine-tuning it could reliably tell the difference between them. Useful? Yes. Neat? Yes. But it’s not like it can identify a cat it’s never been trained on.

So it’s interesting and useful, but not as impressive or useful as the article makes it seem.

Also I’m sure something as simple as changing a nozzle or even what slicer is used would completely throw it off.

All of his books are just wonderful.

Paprika. To see the parade for the first time again… Wow.

Sadly about 50. But that’s all my plan allows at my address so not a hardware issue.

I’m on 1.2gbps with my own modem… That’s the fastest available at my address.

Not what you’re asking but since it’s been covered well:

Buy your own cable modem and put your own firewall behind it. Not only will this save you money in the long run, you’ll also have no issues with things like port forwarding. I use Comcast/Xfinity with a docsis3.1 cable modem + a decent firewall and it’s a good way to go.

You’re thinking of profit. Revenue is all money coming in before expenses. Revenue is still a big number even if they’re losing money.

Thank you, very helpful! And also thanks for putting this info on lemmy :) I figured asking the question here was a good way to get some of that insight here.

Oh I didn’t realize that, thanks!

Ooh I’ll look into Mayan. Seems very feature rich. Thanks!

Thank you! This really helps

Depends on the country / provider. Many cell companies provide battery backup & even gas generators

Came here say this. Absolutely agree. Being able to reduce background noise is huge.

As a side point - having a car that’s quiet has really allowed me to enjoy music at a much more reasonable level when driving as well.

… they sold it off to squarespace

Does it line up with the bottom of the z? If so - is it doing solid infill layers for the top few layers?

Thanks for the recommendation!

Wow looks great! Thanks for sharing.

Hey, thanks for your interest! I edited the post to add an ‘exploded’ view of the parts. This is prototype #2 and still has some significant issues that I’m working on (and would love community input on!)

My strategy for a watertight print is as follows:

• lots of perimeters and solid layers top/bottom on the individual parts
• sand mating surfaces smooth and add TPU grommet/seal
• apply significant pressure to compress the TPU to form a seal

This has actually worked extremely well. The pump has leaks but none of them are from the 3d prints or mating surfaces. What I’m struggling with is preventing water from going out the shaft tunnel. This is a major issue because I’m currently using a chrome-steel bearing at the top for shaft concentricity, which will rust out almost instantly. I made the challenge harder for myself by using a hexagonal drive shaft so I can’t rely on tight tolerances there to keep out the water. I need to sort out a strategy for packing / sealing and/or switch drive shafts + use some kind of off-the-shelf option.

I’ve also been looking into an alternate bearing solution e.g. ceramic. If I can find a good sealed bearing that won’t rust I might be able to just use a tight TPU seal between hex shaft and bearing ID to give it a watertight seal.

The original design had several chrome steel bearings in it (newbie mistake) which I had to replace at the last minute with the nylon bushings. I’m working on a better solution.
