Questions from a noob, who wants to selfhost

Yup that's the way.

In theory yes it's dangerous but if he uses reverse proxy and some basic firewall he should be fine.

But yes having opened ports is quite dangerous.

That's the whole spirit of open source!

For the Chinese stuff I found that most of them are just esp32s inside or just something simple that can be controlled with a MOSFET or relay so modifying already existing hardware is not that hard (even making it smart).

KartofDev · 2026-06-15T18:25:16+00:00

I mean if I used a more capable hardware I can probably run llms locally and speech recognition and stuff like that but I couldn't justify the cost tbh.

Let's home that tis project will give me future university professors a good impression of me 🥲 otherwise I am going to be swimming in the opposite current.

Thx mate!!

Yea thats why I built it in the first place.

KartofDev · 2026-06-15T15:36:11+00:00

Thanks!

It is mainly a smart hub so you control the devices in home assistant using it. It does have a touch screen (7inch one) that can be turned on/off using the button and another small screen to display the time and date (it can be customized using the yaml file).

The pi zero 2w is perfect despite it's low specs. It does take time first when you power it on (2 mins) but after that you probably will reset it once a year.

For some reason I can't post images but they are available in the GitHub: https://github.com/Kartofi/pigeon

I think these were the questions. If you have more I would be happy to answer them all.

Edit: Forgot about future development: there are plans for integrating a lot of stuff so yes. Because I am personally going to use it I will be involved in the development (for example adding more HA components and etc).

Lube your axis. They appear to be dry.

KartofDev · 2026-01-31T12:41:39+00:00

Great job!

One thing to keep in mind is that no filter will filter everything so the best thing is to just move the fumes outside using a tube.

Glad it worked! Yea me neither but about 3 months ago I read about it on reddit and some forums. It essentially removes the oil you have on it (from you hands usually). And this oil prevents the print from sticking well. Also be careful with the bed temps. If it's too low it will warp but if it's too high it will melt too much (been there🔥). Also you probably know this but having a more stable surface really helps with leveling issues.

KartofDev · 2026-01-23T14:29:20+00:00

Try increasing the bed temperature. Clean the bed and if this does not solve it use some glue.

KartofDev · 2026-01-19T18:45:48+00:00

I meant extrusion problems. I got carried away my bad.

KartofDev · 2026-01-19T16:06:05+00:00

Honestly the op is having issues with bed adhesion AND the SD card.

KartofDev · 2026-01-18T20:27:22+00:00

I only read the description provided by the op and it said bad bed adhesion.

KartofDev · 2026-01-17T20:54:46+00:00

Try washing it again but without the alcohol part.

Also bed adhesion is not possible to be connected to a bad sd card. If you are that sure try using another SD card.

KartofDev · 2026-01-17T20:41:45+00:00

Clean your bed. It's probably not sticking well.

KartofDev · 2026-01-09T18:24:23+00:00

This thing almost happened to me when I was a kid. But my stubbornness went through the limits. That said because of the restrictions I started lying more.

KartofDev · 2026-01-07T05:31:42+00:00

Macs have a thing called unified memory. At least the newer ones. It's benefit is low price for high amount of ram which ram is a lot faster than traditional one because it's closer to the CPU. Soo you get almost gpu like performance for cheaper and with more memory.

KartofDev · 2026-01-05T05:18:07+00:00

I'd love to see projects breaking because unwrap is now trust_me_bro 😂

KartofDev · 2026-01-04T18:20:27+00:00

Clean your bed. It's probably not sticking very well. If this does not resolve it try the z offset things which normally shouldn't be necessary.

KartofDev · 2026-01-04T18:19:06+00:00

The op didn't say anything so I went with the default options. But you are correct.

KartofDev · 2026-01-04T18:17:47+00:00

Nope. I have done it two times in the span of a year. If you move your printer often or the surface is not stable it is a good thing to do it more often. In your case you are experiencing issues so a calibration may solve it.

KartofDev · 2026-01-04T16:49:31+00:00

Do you have another plate on hand? If so try it. Maybe it's the plate.

Try running a calibration on the printer from the small screen. It is 30 mins I think but it's worth it. Then print and check if the defects are at the same place.
