  • 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









  • 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 personally think some types of openly developed software projects should have a strict non-commercial license: if companies aren’t willing to contribute back to the source IMO they shouldn’t be granted permission to freeload & have volunteers fix issues their paying customers run into

    Donations are possibly a bit of an exception here - there are quite a few companies that still do this, albeit growing slimmer by the day.

    Another big problem IMO is the subset of users that start attacking maintainers and volunteers because their “free app stopped working” etc. I see that a lot, mostly in the arduino community, but especially egregiously on the Zabbix project - I imagine a lot of those users are companies who aren’t even paying/donating to the project



  • 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

    Unironically this…

    Passkeys don’t work on my rooted device - they seemingly set up correctly, but sites like GH claim your device passkey doesn’t exist when you try to actually login. When you go to the affected site’s account settings to add the device as a passkey again, an error of some kind claims the passkey already exists 🤷‍♂️

    Deleting/re-adding has no effect. Using FF with device biometric passkey auth
