07:09 AM lcnc-relay: <meisterdippel@> hi
07:24 AM JT-Cave: no phone service since yesterday noon
08:20 AM lcnc-relay: <oddname_skane@> wuddap boyos
08:34 AM lcnc-relay: <skunkworks8841@> huh - I just do everything with sudo menu-config
08:52 AM lcnc-relay: <skunkworks8841@> linuxcnc has been running 3 days? 2 days with a 40us base thread. No realtime errors
08:53 AM lcnc-relay: <skunkworks8841@> I will make up a config and see how the gpio works

11:29 AM lcnc-relay: <meisterdippel@> [ 0.527996] nvme nvme0: failed to allocate host memory buffer.
11:30 AM lcnc-relay: <meisterdippel@> hmm, not good
11:35 AM lcnc-relay: <roguish> meisterdippel@: listen closely to Tom_L. he definitely knows what he's talking about
11:40 AM lcnc-relay: <meisterdippel@> yes, he says, buy RPI5 🙂
11:48 AM * JT-Shop hears a nap calling his name
11:50 AM lcnc-relay: <meisterdippel@> aliexpress have mesa clones now 😱
11:51 AM lcnc-relay: <roguish> don't touch 'em
11:51 AM roycroft: no they don't
11:51 AM roycroft: they either have things that purport to be mesa clones but really aren't, or they have counterfeit mesa boards
11:54 AM lcnc-relay: <meisterdippel@> they have boards with spartan6 that are compatible to mesa gateware, some looks not sooo bad
11:56 AM lcnc-relay: <meisterdippel@> Then I have to adapt RIO so that it can handle the MII network ports.
11:59 AM lcnc-relay: <meisterdippel@> with the original raspi image the nvme works
12:01 PM -!- #linuxcnc mode set to +v by ChanServ
12:02 PM rdtsc-w: the "devil is in the details"
12:07 PM lcnc-relay: <meisterdippel@> running on nvme now, will test installing linuxcnc+kernel on trixie
12:23 PM roycroft: the person who sold me the motor that failed responded to my request for warranty service with an offer to sell me another motor
12:24 PM roycroft: i'm not surprised to get that as the response, and in fact am a bit surprised to have gotten a response at all
12:24 PM * roycroft will let ebay or paypal handle it from here
12:24 PM xxcoder: what failed on the motor anyway
12:25 PM roycroft: i'm already finding the portable air compressor intolerable
12:25 PM roycroft: bearings, at least
12:25 PM roycroft: i have not pulled it and disassembled it yet
12:25 PM roycroft: but the sound it makes tells me it's seized bearings at the very least
12:25 PM xxcoder: interesting. if paypal refunded, then I guess you could try rebuild it
12:25 PM roycroft: and if that's all it is i can purchase new, higher quality bearings
12:25 PM roycroft: exactly
12:26 PM roycroft: that's probably the best outcome - to just get a refund that i can use to purchase proper bearings
12:26 PM roycroft: i'll pull it tomorrow or over the weekend
12:30 PM xxcoder: wouldnt it be better to wait for whole thing is settled first?
12:30 PM roycroft: ebay just told me that their carrier, allstate, will handle the claim, and are emailing me info on how to open a claim
12:31 PM roycroft: so i think it's handled
12:31 PM xxcoder: ok
12:32 PM roycroft: shandongaifuqichelingbujianyouxiangongsi
12:32 PM roycroft: that is the seller's name - they just sent it to me
12:32 PM roycroft: i think that even if you're chinese that would be a difficult name to pronounce
12:35 PM roycroft: almost as hard as johann gambolputty de von ausfern-splenden-schlitter-crasscrenbon-fried-digger-dangle-dongle-burstein-von-knacker...
12:35 PM lcnc-relay: <lesliet@> neither one of em getting the birthday song
12:35 PM xxcoder: yeah if I have to fingerspell that, I'm skipping the name
12:36 PM roycroft: maybe the good birthday song - stevie wonder's
12:36 PM xxcoder: I would just sign "Your name" or something
12:36 PM lcnc-relay: <lesliet@> or the other good birthday song ( the dirge)
12:37 PM roycroft: although that one is only about a particular person's birthday, not generic birthdays
12:39 PM * roycroft likes stevie's song better
12:39 PM roycroft: it's happier :)
12:39 PM lcnc-relay: <lesliet@> I find it a little puzzling that Chinese manufacturers don't hire better translators, both for product manuals, and for their ads and product names
12:40 PM lcnc-relay: <lesliet@> unless names like "yusuq" are intentional?
12:48 PM lcnc-relay: <roguish> they're probably running AI translators.
12:51 PM roycroft: the chinse manufacturers who export to the us discounters, for the most part, don't care about anything but getting product out the door as cheaply as possible
12:51 PM NetPipe: https://i.imgur.com/xPadnA1.png getting ready to laser one of these
12:54 PM roycroft: that said, chinese manufacturers can make very high quality product, if that is what is demanded of them and if that's what they are paid to do
12:54 PM roycroft: it's not that all they can make is crap
12:54 PM xxcoder: its very much get what you pay for. they will cut product down to pay level rather than negotiate prices
12:55 PM roycroft: it's that they're willing ot make crap if crap is what is requested
12:55 PM roycroft: and most of the time, crap is what is requested
12:55 PM roycroft: even when not explicitly so
12:55 PM roycroft: exactly what xxcoder said
12:56 PM roycroft: "i want you to make this $180 part and i'll pay you $50 for it"
12:56 PM roycroft: the response is not "we can't make it for $50"
12:56 PM roycroft: the response is to deliver a $50 part that resembles the $180 part
01:01 PM roycroft: allstate want pictures
01:02 PM roycroft: i told them there is no external damage, and pictures won't help
01:02 PM xxcoder: as well as make video
01:02 PM xxcoder: make it go loud
01:02 PM roycroft: i can send them a video with audio of the screeching sound and the circuit breaker popping
01:13 PM lcnc-relay: <meisterdippel@> oookkk, works now, original image on nvme with some parameter added to cmdline.txt
01:30 PM rdtsc-w: please put a note in the forum :)
01:50 PM JT-Shop: verizon is still saying cell service will return at 5pm
01:50 PM xxcoder: that sure destroyed the 9s
01:50 PM roycroft: spectrum provide all their outage announcements/updates via email
01:51 PM roycroft: so whenever i have an internet outage, i get all those updates once service is restored
01:51 PM roycroft: they say i can visit their website for updates, but that's the same problem
01:51 PM xxcoder: reminds me of that time a phone company required phone calls to inform them when phone dont work
01:52 PM JT-Shop: sounds about right
01:52 PM JT-Shop: in any case the trailing arm is rebuilt and ready to put back in the C3
01:52 PM roycroft: and regarding using cellular data to get the updates, my cell service is also spectrum (the only carrier that works here), and their data service goes down whenever their internet service goes down
02:07 PM JT-Shop: I just got a call from comcast saying my 50% discount is about to expire LOL
02:09 PM roycroft: i had comcast for internet service for over 20 years
02:09 PM roycroft: they were always ready to offer another discounted package when one was about to expire, on a 1 year contract
02:09 PM roycroft: and that was the game i had to play for all those years - contact them for a new deal before the old one expired
02:10 PM roycroft: spectrum don't play that game at all
02:10 PM roycroft: they offer a sweet deal for the first year, and then, no more deals
02:10 PM roycroft: but where i live they are the only game in town, and they know it, and so they set the rules
02:13 PM JT-Shop: it's funny because I don't use comcast
02:13 PM JT-Shop: so it's spam
02:25 PM xxcoder: for me most recent scam attempt was "lost contact friend" from calfornia
02:25 PM xxcoder: supposely I had met that person few months ago in calfornia
02:26 PM xxcoder: but last time I went was in 2021, and it was very brief visit
02:55 PM rdtsc-w: I did tech support for Comcast and AT&T Broadband for a few years... may have seen it all, from a guy about to cry because of needing to disconnect his internet obsession, to a conspirist whom was certain we were recording their household and selling it to the NSA
02:59 PM roycroft: i've found that scam calls have almost completely stopped since the new stir/shaken regulation went into effect a couple weeks ago
03:00 PM roycroft: i was getting 5-10 calls/hour right before then, now i get 1-2/day at most
03:00 PM roycroft: it's really nice, and i hope it lasts
03:14 PM Unterhaus_ is now known as Unterhausen
03:17 PM xxcoder: nice
03:41 PM rdtsc-w is now known as notunderhausever
04:22 PM notunderhausever is now known as rdtsc-w
05:41 PM lcnc-relay: <lucid.nonsense@> rdtsc-w: Wrong and maybe not that wrong 😅
06:12 PM lcnc-relay: <lucid.nonsense@> Watching rotarySMP and wondering how difficult would it be to have something like a tinyML "supervisor" sanity check with a camera that paused jobs if something was definitely about to go wrong
06:13 PM lcnc-relay: <lucid.nonsense@> "Do you really want to do this?"
06:17 PM lcnc-relay: <skunkworks8841@> Maximum veloctiy override on a mpg really helps these sort of problems..
06:17 PM lcnc-relay: <skunkworks8841@> you slow the maximum velocity down to the point that you can see what is happening..
06:18 PM lcnc-relay: <lucid.nonsense@> I bet
06:18 PM lcnc-relay: <skunkworks8841@> plus 'distance to go' is your friend.
06:21 PM lcnc-relay: <lucid.nonsense@> I suppose the value of something like an esp32 tinyml setup is that it could potentially catch electrical or noise related malfunctions

08:28 PM xxcoder: whew rice was yummy
08:28 PM xxcoder: havent had rice besides sushi for a while
10:07 PM lfluffywof is now known as fluffywolf
10:53 PM roycroft: well, the seller just refunded the full amount i originally paid for the motor and told me not to ship it back
10:53 PM roycroft: this, after the seller had already refunded me $75 when i got it because it was the wrong motor
10:54 PM xxcoder: dang
10:58 PM roycroft: i hate having to deal with problems like this, but they alway seem to work out in my favor
10:58 PM roycroft: i'm still not sure it's worth the hassle most of the time - i'd rather just get what i ordered and have it do what i need it to do
11:00 PM roycroft: so i guess now i can pull the motor and decide to either buy good bearings for it or buy another motor
11:00 PM roycroft: hopefully it just needs bearings, in which case that's what i'll do
11:02 PM xxcoder: yeah. bet its a hassle. I had recent buy refunded as it didnt work
11:04 PM xxcoder: it was supposely water mover, it moves water arpund in bucket to clean small amount of clothes
11:05 PM xxcoder: supposely 30 sec one direction and then reverse direction
11:05 PM xxcoder: but after I got refund due to it not working properly, I opened it and it was just dc motor. no smarts at all
