  • AFAIK on Windows the physical disk containing the partition needs to be marked offline in Disk Management, and the disk or a partition given exclusively to VirtualBox running as administrator, otherwise access is limited to read-only

    I would suggest checking some other sources as well, just in case this has changed over the years. If you do successfully pass the physical partition into VirtualBox read-write, you might need to set up a virtual disk with grub to boot into your physical Linux partition



  • To answer the direct question - no

    I do have some thoughts on moving away from the Pi though - warning, heavy personal bias ahead

    If you’re looking at moving away from the Pi I would just suggest a low power x86 box, like a Nuc or some Intel N100 low-power tiny PC.

    There is a caveat though - it looks like the OctoPi project only provides OS builds for the Pi, so if you change systems it looks like you’ll need to install OctoPrint manually, and port over your config somehow.

    On ebay you can get second-hand NUCs, 6th gen and up, for practically peanuts. The cheaper quad core celeron nucs (i.e. J3455) are roughly equivalent to the 3rd and 4th gen dual-core i5s (3777u, 3230m etc) performance wise, but have an updated QuickSync encoder and support accelerated 4K video encoding/playback, handy if you want to capture timelapses of your prints or just view them live. They also consume 1/3rd of the power at around 10 watts under the same workload.

    ARM support for other vendors can be pretty flaky, sometimes even non existent. While you could pick an Orange Pi, and go with a modern community-supported distro like Armbian, it isn’t a turnkey experience like the Pi. There is much less documentation, and still some very early boards floating around with hardware defects and overheating issues (posing a fire risk in the worst case, the OPi Zero being the most egregious - literally melting the optional enclosure and killing the NIC). Some research before buying will let you know most of what you need to know - check around the forums for any common issues and dealbreakers, as well as the manufacturer’s site to get an idea of available support.

    If you want to get an idea of the alternatives you could check out Jeff Geerling’s youtube channel, he covers the Pi and occasionally videos on other alternatives, as well as issues he’s had with them and support. I’ll try and link some below…

    Check the comments on that one for a quick synopsis, as the video is quite long…

    This video pretty much just echoes my current perspective




  • Retraction settings are probably your best bet then. Since the SV06 doesn’t use a bowden extruder, there’s much less things that could be the issue in your scenario thankfully

    To be specific about my “workaround”, it compensates for a non-flat build plate (ramped lift) and a cheap nozzle that filament often sticks to (wipe on retract). It took me two days of test prints and research to narrow those down though…

    To get to the bottom of your issue quickly, you could try tuning your retraction using a retraction test, then possibly try recording the nozzle printing the same test at 60/120fps, to play it back in slow motion. This way you can see at what part of the nozzle movement the stringing starts, and change any relevant settings accordingly



  • This looks like one of those low cost netbooks from the time where “EPad” and “MID” tablets were a thing. There is an edition of Windows CE floating around for these - but WiFi will not work, neither the modem if this has one built in.

    No idea about Linux - there is a kernel so you’re technically half way there, but considering most of these had a slow single core ARM CPU and 256MB of RAM on a good day, practical use is limited IMO


  • 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










  • 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
