  • ASMedia is the only controller IC manufacturer that can be trusted for these IME. They also have the best Linux support compared to the other options and support pass-through commands. These are commonly found in USB DAS enclosures, and a very small fraction of single disk SATA enclosures

    Innostor controllers max out at SATA 2 and lock up when you issue pass-through commands (e.g. to read SMART data). These also return an incorrect serial number. These are commonly found in ultra cheap desktop hard drive docks, and 40pin IDE/44pin IDE/SATA to USB converters

    JMicron controllers (not affiliated with the reputable Micron) should be avoided unless you know what you are doing… UASP is flaky, and there are hacky kernel boot time parameters required to get these working on Raspberry Pi boards. Unfortunately these are the most popular ones on the market due to very low cost





  • No - however you could look for macro boards that have VIA firmware, as most of those can be configured using Chrome browser (WebHID), unless your org has an enterprise policy that interferes with that? The config software runs in Chrome as a website - so worth checking if the VIA keyboard web app is accessible on your work machine before purchasing a macro pad.

    VIA firmware stores the config in the keyboard’s internal eeprom AFAIK, so you should be able to setup your macros from another computer or android phone and still use them when connected to your work machine - unlike other software like Logitech Options where the config is deleted from the peripheral after a connection interruption…

    Does your employer have a policy allowing you to request software to be installed on your machine, especially if it’s needed for work? I had Logitech Options installed on my first day with no hassle from IT. Your situation sounds a lot like an unfortunate case of possibly power tripping IT admins doing more harm than good


  • This kind of stuff happens all the time IMO, we’re human and not perfect 🤷‍♂️

    I don’t know how much of a help ChatGPT would be in this situation without access to your schema, at least with Copilot you can write a comment in the code explaining what you’re trying to do and get some usable pointers in the generated suggestion (which takes your codebase into account).

    I usually try to get a second pair of eyes on my code if something that seems relatively simple isn’t working as expected… As you gain more experience these mistakes will become less common, and easier to spot




  • I used to use MQTT, static_status and Healthchecks.io, and have that data passed through to Home Assistant, but it started to get pretty cumbersome as the amount of machines I had grew.

    I now use just Zabbix and HealthchecksIO. I did need to spend some time writing new templates for some additional data I wanted to collect (like SMART data for SSDs that provide health metrics in non-standard attributes, and HealthchecksIO so I could see the status of various checks on my zabbix dashboard)

    Zabbix also has some additional features I found appealing, like proxies that can continue recording data when the main server is down, and built in encryption. Some checks like open ports/icmp responses etc can be checked using either the local agent, the remote server, or both, which helps quickly diagnose things like firewall config issues.

    I did look at some other solutions, but I wanted something integrated to hit the ground running. Mobile apps are very limited, and there is no official one to my knowledge. I use Moobix which I don’t believe is FOSS - but I could be wrong there

    Try each solution out and see what works best for you!



  • I had a similar stringing issue with PETG on my flsun Q5, where PLA was printing flawless without any strings whatsoever. Since your SR isn’t a bowden, that mostly rules out retraction distance IMO.

    For me I narrowed it down to Z-hop: as the printer was lifting the nozzle slightly to move to another part of the print, molten filament oozed out - sticking to the print, and getting stringed across by the nozzle. I only noticed after recording the print (use at least 60fps to avoid the frame blurring you’ll get at 30> and watching what exactly was happening prior to the stringing. It took about 4 hours to get to that point 😭

    If orcaslicer is based on Prusaslicer, wipe on retract with the initial distance set to 100% may not trigger a wipe. Try 70% or 80% instead. There’s another setting somewhere to force retraction when changing layers: enabling this will forcibly honor your wipe retraction preference when changing print layer.

    I think you may still get stringing at the really spiky parts of the test print, given there’s no space for a wipe, and that volcano is going to hold way more molten filament than a V6 or similar

    Hopefully someone with more experience can add their 2¢, it was pretty difficult to research info online when I had PETG stringing - everything just says “tune your retraction” 😤

    Edit: I mixed up the SR with the v400! In that case, Another thing to check is your bowden tube pneumatic couplers - unload the filament and tug lightly on each to see if they’re fitting securely. If they’re loose, your extruder can end up moving the bowden tube itself back and forwards, which affects your retraction



  • I don’t have hands-on experience with any of the brands listed so sadly can’t give specific recommendations

    Would a second-hand Google Pixel work fine for you, or do you definitely want to buy new? Mobile devices are really reliable nowadays, I doubt you’ll need to worry about a warranty (which would not cover accidental damage, like a cracked screen)

    I’ve noticed most countries outside of the US and Europe (making that assumption based on inability to get a Google Pixel or a Fairphone) typically have some locally used apps preinstalled regardless; usually a social networking and mobile e-payment app. I’d expect it to be possible to remove these using ADB if you have access to a computer.

    Are you buying direct from manufacturer, or via a carrier? Do note that carriers may have customized the apps installed on your device if you buy one through them. For the least preinstalled bloat, buying direct is ideal




  • Yepp I know - my preference leaned towards the server edition as it doesn’t include the unnecessary UWP apps installed with Win10/11, and has a much lighter footprint in comparison, resulting in less resource usage overall.

    If these were Windows 7 or Windows XP days, a professional edition install would have sufficed for me tbh… but with all the Metro UI and additional telemetry in Windows editions after 8, it doesn’t seem worth the hassle.

    When I need to log in and fix something now I really wouldn’t want to stare at a “please wait, we’re upgrading your apps” because some UWP update occured, or have the telemetry service gobble up idle CPU





  • I like having options and the versatility personally 😁

    The 3.5mm jack can also be used to record video audio with a much better microphone, attach a HW infrared blaster, or use your device as a crude oscilloscope im a pinch with appropriate software

    The more common use case is people with existing wired headphones - there’s honestly no need to cast aside perfectly good cans for no reason. Yes USB-C DACs exist, but IMO that’s a completely manufactured expense and inconvenience, considering almost all phones still have the 3.5mm dac and amplifier components physically present on the mainboard: only now you must purchase a dongle to access the output via passthrough, or purchase a third party dongle that includes its own DAC.

    My pain point though is the fact that users with wired headphones are now being forced to induce more usage cycles on a single connector port (which is not always economically repairable on modern devices), and all the avoidable e-waste produced by these things when the unreplaceable, consumable batteries give up the ghost after two years of ownership
