  • Not the case with ARM processors sadly, IMO they’re a bit of a mess from that perspective. Proprietary blobs for hardware, unusual kernel hacks for some devices, and no device tree support so you can’t just boot any image on any device. I think Windows for ARM encouraged some standardization in that regard, but for the most part looking at Android devices it’s still very much the wild west.

    This is one of the many reasons why Raspberry Pi ARM boards remain popular for the time being, despite there being so many other cheap alternatives available: they actually keep supporting their old boards & ensure hardware on their boards works from the get-go.

    There are also some rare cases where Raspberry Pi rewrite open source implementations of Broadcom’s proprietary blob drivers, in one instance for the built in CSI (optional camera)



  • 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






  • 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
