Since I once had the case where junk on the line (from a wiggly connection) caused Magic Sysrq requests I'm fully on your side. No junk tolerated for potential hot plug connections.
I'm aware of serial breaks, but this is the first I've heard of them being interpreted as SysRq by Linux. That could be handy. Thanks for the tip.
I assume the possibility of spurious Rx state is why FTDI chose to wire Rx to the tip pin of the female TRS connector: It's the last pin to make contact with anything when plugging in, and therefore least likely to be bridged to ground. I suppose the mechanical design of any particular jack would determine whether it's possible at all.
> you can always try the plastic bag + vacuum cleaner trick - take a thin flexible rope, tie it to a small plastic bag, stuff the small plastic bag into the conduit, use a vacuum cleaner at the other end to suck the plastic bag & rope through.
That's absolutely great! Worked like a charm two days ago and everybody cheered and laughed who saw it :-D
Back in my day the local telephone company used waxed lacing cable for that sort of thing[1]. These days it seems that polypropylene string is popular (search on "conduit pull string").
You basically want something that is slippery and will tend to not get stuck. I have used Dacron fishing line, but that is mostly because I had a bunch of it laying around.
I'm a bit surprised that nobody mentioned prusa as a replacement?
FMU that's where Bambu originally copied from!?
My short dive into 3d printers stopped once I was highlighted to the micro plastics pollution they create in the air, but still I would've gone for a prusa, already because all parts are free soft- and hardware.
Prusa is not even fully open source anymore, bunch of excuses.. and definitelythey have a pricing god complex...
Bambu still the best machines to date, especially if you consider price. If you do not upgrade NOTHING changes - and its only planned for the X-series as of now. People are being too hysterical.
> I'm a bit surprised that nobody mentioned prusa as a replacement?
Prusa has a pricing issue, I don't think there's another way to go around it.
I've been in the market for a 3D printer, and Prusa is rarely recommended for entry / mid-range printers (at least where I've looked).
I don't know about the high-end range, but a lot of content about high-end stuff still revolves around Bambulab X1C—those content creators could be paid for, of course, even though many claim they aren't. Just seems like Bambulab printers are really good for the price.
Now I get that Prusa is positioning itself as a local manufacturer in EU, and they are just a representation of the cost of making products in this setting - and I'm ok with this! I won't pay for it because I'm not their target customer, but I support it 100%.
