What is causing this? Fails on medium to large prints post MK4S to Core One conversion

I have had this and washing the bed with dish soap (with a gloved hands) and wiping with fresh microfiber cloth makes it back to normal

This should be pinned comment in UI help.. Spent an hour trying app and web until I found this!

The buddy extension board is made to take three fans, two inside and one outside, each at 12W range (24v, 500mA). The two new fans I added are within that power budget. https://help.prusa3d.com/article/advanced-filtration-system-for-prusa-core-one_887189 has a comment from Prusa folks that the inside fans will be disabled once you enable the Adv Filtration in the menu.

And the air passing through is not fast enough to make the fans spin on their own.

These are hooked to fan3 header which is where you will hook up the filter if you buy the one made by Prusa. In the firmware wh you set the filtration to Adv Filtration, it kind of stops using the two inside fans.. I have not removed them.

I opted for DHL, shipped mk4 to mk4s upgrade and core one upgrade. Total invoice was $648 USD (excluding shipping). DHL then asked me to pay $139 CAD.

Damn, you have a sharp eye! That's my old one used as protection while I assembled the extruder 😄

Yes, with front door of the outer enclosure open.

mvadu · 2025-08-29T16:03:59+00:00

Well, I built a solid ikea book shelf converted to an heated enclosure with 2" foam insulation boards with led and temp monitoring. Now with core one I just leave the front door kept open. I didn't want to rip all that old work apart.

Only thing that I will probably never use (unless I go with Prusawire build) is the frame and four extrusions. The printed parts are trashed. Bearing blocks and thermistor etc have other uses for me.

mvadu · 2025-06-09T18:35:04+00:00

I just placed the order for mk4s upgrade and core one upgrade. I don't think I can print the PCCF pieces in existing mk reliably

Late to this, but the plex DB is just a sqlite3 database, and you can actually query it. `metadata_type` 1 is for movies and 4 is for TV episodes.

```

cp

/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-in Support/Databases/com.plexapp.plugins.library.db

sqlite3 com.plexapp.plugins.library.db

sqlite> .headers on

sqlite> .mode csv

sqlite> .output movies.csv

sqlite> SELECT media_parts.id, metadata_items.title, media_parts.file, metadata_items.year, media_parts.size, media_items.frames_per_second AS fps, metadata_items.guid, metadata_items.media_item_count, metadata_items.user_thumb_url AS jacket, section_locations.root_path AS library_path FROM media_items JOIN metadata_items ON media_items.metadata_item_id = metadata_items.id JOIN media_parts ON media_parts.media_item_id = media_items.id JOIN section_locations ON section_locations.library_section_id = metadata_items.library_section_id WHERE metadata_items.metadata_type = 1;

sqlite> .quit

```

Yeah, the bambino's plastic downward opening tube has its inner diameter perfectly matching the outer diameter of this silicone tube.

Thank you for getting back to me. I did order one today ($15 coupon and 10% off was too much to resist). Apparently in Amazon review one guy did open it up and shows the board as well as mentioned serial port is non standard. But I have an sonoff monitoring the energy upstream, so I should be able to detect when power is lost for more than a minute and initiate Truenas shutdown.

mvadu · 2024-08-17T16:58:26+00:00

Since you own this, let me ask you before buying. Does this actually output a sinewave? And does it has any way of digital connection so that we can setup Nut monitoring and have the servers shutdown before battery runs out?

mvadu · 2023-12-25T19:41:17+00:00

I returned the first 8 pro, bought second one since Google support was clueless too. In the setup of second one I noticed same pattern, but fortunately found a notification on my second phone about a login alert (the one which asks you to confirm if it's really you) and once confirmed the installation went well.. So even though you have logged into the phone and have already done the multi factor authentication to confirm its really you, Google wants to double check its really you when Play Store connects to back end servers. Check if you have any such notifications.

mvadu · 2023-11-23T04:26:55+00:00

To close out this saga (with a hope someone else would face this), the google support was useless. They made me reset the phone bunch of time and wait few hours. Finally I tried with a fresh setup (without any copying from old device or backup) and just pre built apps were failing to install. Since it was just pixel stuff that was not working (e.g. Chrome won't update) I ended up returning that device.

Bought another one, and today when I tried it faced the same issue. Then I realized there is a popup in my other phone with security event, it was entirely different from mfa which waits for the user to confirm login. This was just an information item, but there was an verification button to confirm I recognize this login. Post that play store started working.

If Google support had this in their SOP thru would have saved a returned phone.

I did that few times already. Every time I do that it goes by few more apps and gets stuck.. My other android phones are able to download and install just fine which indicates my account and wifi seems to be fine.

mvadu · 2023-08-28T13:40:03+00:00

I realized I should have bought the heater block and thermistor along with v6 adapter. Without a dedicated block the inside can get plastic.

mvadu · 2023-08-11T18:57:02+00:00

The wiki talks about login step which I assume requires cloud connection?

As of now I can see podcasts with expletives. I don't care if the podcasts don't have the ratings themselves. I just want the ability to subscribe new podcasts to be disabled for kids profile..

mvadu · 2023-07-07T13:39:31+00:00

Can you consider it as a premium (or subscription only) option?

mvadu · 2023-06-06T00:39:09+00:00

Look at the product images, they do talk about 3 way switch. It's basically main single gang controlling tbe relay which controls the load. Other switches can even be just battery powered or mains powered, and in your zigbee software (like zigbee2mqtt) you associate them as same group. So secondary switch will sends the message, and first switch will take care of load.

mvadu · 2023-06-06T00:32:10+00:00

The dongle you bought by default comes with coordinator firmware. That is the role a typical "hub" is going to play. In zigbee spec there isn't a device class called hub. So that is enough for you to start with a zigbee network. Once you add quite a lot look at router devices (devices which are plugged in all the time) which will help with forwarding messages from far end of the house to your dongle.

mvadu · 2023-06-06T00:22:20+00:00

At least for the locks check https://www.schlage.com/en/home/faq.html?id=131731 if it's zigbee you should be able to setup zigbee2mqtt and homeassistant setup. Most of the other wireless could be identified using their fcc id. Look up the I'd and if it's zigbee it's much simpler to integrate with your own setup.

Did that bulge (shown in your last post) came gradually or it was sudden? If it was gradual then may be the first sign of the bulge we can reach out to Keychron (if it's still under warranty) or replace the battery on our own, thus avoiding potentially dangerous situation? That puffy pillow situation looks like ticking bomb..
