03:43 AM travis_farmer[m]: G'Morning
04:47 AM Tom_L: morning
05:00 AM JT-Cave: morning
05:37 AM Deejay: whoopsie, wrong cable :D
06:43 AM justache is now known as deliriumt
06:44 AM deliriumt is now known as justache
07:42 AM perry_j1987: morning
08:02 AM perry_j1987: quiet this morning
08:06 AM travis_farmer[m]: must be either everybody is still sleeping, or working on something. ;-) i for one am finishing up a little work. sanding and applying tongue oil to some big rolling pins for a customer (in on break at the moment).
08:07 AM perry_j1987: im working on some cad work right now
08:20 AM JT-Cave: I'm fixing to start a couple of fires then clean chicken shit
08:21 AM travis_farmer[m]: suddenly my job sounds better... ;-)
08:26 AM -!- #linuxcnc mode set to +v by ChanServ
08:27 AM * JT-Shop decides it's not cold enough to start a fire in here and goes straight to cleaning chicken shit
08:32 AM perry_j1987: putting up that much of a protest before cleaning the coops lol
08:32 AM perry_j1987: considering turning to arson to get out of it lol
08:48 AM unterhausen: What kind of tongues is tongue oil made from?
08:48 AM unterhausen: hopefully not chicken tongue
08:49 AM CloudEvil: I suspect you mean Tung.
08:49 AM CloudEvil: It's a type of tree.
08:52 AM unterhausen: you don't even have to scroll up to see what I'm talking about
08:53 AM CloudEvil: He means tung.
08:53 AM CloudEvil: And, yes, I did
08:54 AM CloudEvil: It is one of several natrual oils used as a wood finish as they 'dry'. (polymerise under the influence of atmopsheric oxygen and other things)
08:54 AM c101horse8332[m]: Im stuck in a technical basement putting in 2.5" cooling and compressed air lines
08:54 AM c101horse8332[m]: Its dark down here
09:06 AM CloudEvil: Good luck with not getting them mixed up.
09:48 AM c101horse8332[m]: Yeah, that'd make a mess
09:56 AM unterhausen: for whatever reason I always started plumbing projects at work at 4pm on Fridays
09:56 AM unterhausen: and the air bearings could only be off air for so long before it became a problem
10:11 AM unterhausen: I saw someone with a pica deep hole marker on insta
10:12 AM unterhausen: looked it up on amazon and they suggested I get a sharpie instead
10:14 AM unterhausen: I never realized there was such a thing
10:14 AM travis_farmer[m]: CloudEvil: yes, tung, spelling is not my strong point, and spell-check got it wrong in that instance. ;-)
10:15 AM travis_farmer[m]: finished work for the day, so after lunch, i get to play :-)
10:39 AM unterhaus_: funny thing is, I always misspell tongue. Tung I can spell right all day
10:58 AM unterhaus_: one hour until they doc tries to focus a laser on my eyeball.
10:59 AM unterhaus_: Things you don't want to hear your doctor say: "see, that didn't hurt me at all"
10:59 AM Tom_L: hope he's a good aim
11:03 AM jdh: Anyone have a copy of NT3. 5?
11:04 AM unterhaus_: what do you need NT 3.5 for?
11:04 AM unterhaus_: I guess they changed everything with NT 4
11:05 AM unterhaus_: I might actually have a copy of NT4, I used to subscribe to their developer service
11:05 AM jdh: I have NT4
11:07 AM Tom_L: mmm i may have upgraded but i'm not sure what i upgraded from to NT4
11:08 AM Tom_L: i do have NT4 as well
11:08 AM Tom_L: what did you need off it?
11:12 AM unterhaus_: I'm guessing he wants to run an obsolete video capture card
11:15 AM unterhaus_: the ophthalmologist keeps telling me they are using a YAG laser. That seems like a weird detail
11:15 AM unterhaus_: I'm glad they aren't using a green laser pointer they got from ali express though
11:18 AM Tom_L: nt, nt server, xp pro, 95, 98... i dunno what i upgraded from
11:18 AM jdh: Old code that only seems to work on NT3. 5
11:19 AM jdh: Tech80 5641 ISA board.
11:20 AM Tom_L: odd it wouldn't work with 4
11:21 AM unterhaus_: yeah, I ran some keithly isa cards under 4
11:21 AM unterhaus_: native 4 has horrible latency though
11:21 AM jdh: Yeah. Not 100% sure that is the problem but it has been working for years
11:22 AM unterhaus_: 3.5 to 4 was a huge change
11:22 AM Tom_L: i must not have had 3.5, i sure don't remember it
11:22 AM unterhaus_: I may have never run it, 95 was contemporaneous
11:23 AM unterhaus_: 95 is far superior to anything that came after for controlling a machine
11:24 AM unterhaus_: I always just used dos though
11:25 AM jdh: This was the DOS upgrade for this system
11:32 AM unterhaus_: our moore nanotech ran on 95, I'm surprised the IT guys didn't take it
11:32 AM unterhaus_: it was never on the interwebs though
11:32 AM jpa-: jdh: https://archive.org/details/windows-nt-3.5
11:34 AM unterhaus_: moore wanted $25k to upgrade, so it never happened
11:35 AM Tom_L: i have that disk but it doesn't say 3.5 on it
11:47 AM unterhaus_: Tbh, if I had 3.5 I hope I threw it away
01:13 PM Rab: 3.5 as I recall was pretty solid. 4.0 Server could be very reliable. I once maintained an office PBX running on 4.0 which never gave me any trouble. NT 4.0 Workstation was a bloated, fragile mess.
01:14 PM Rab: I am not sure what differentiated Server and Workstation, but I think Workstation invited third-party graphics drivers into the kernel or something.
01:16 PM Rab: 95 was just a crappy little thing, but you could reboot it and keep trucking; faster and easier to install than the others.
01:18 PM Rab: Slackware Linux was absolutely amazing compared to all of that stuff. Even the clunky desktop options.
01:34 PM roycroft: well yay - i just had a brilliant idea
01:35 PM roycroft: i'm still trying to sort out how to hold workpieces vertically in my cnc router
01:35 PM roycroft: i keep seeing solutions where folks add a panel to the end of the machine and mount the workpiece vertically there, or have a big gap in the bed and mount the workpiece in the gap, with clamps underneath the bed
01:36 PM roycroft: but i don't see why i can't mount the workholder clamps on top of the bed
01:36 PM roycroft: and just have a narrow slot for the workpiece to fit into on the bed
01:36 PM roycroft: that's actually pretty easily doable
01:37 PM roycroft: this is why it's good that it's taking me going on three years to design the bloody thing - i come up with better ways of doing it the longer it takes :)
01:38 PM roycroft: so theoretically, if i take an infinite amount of time to do the design, i'll have designed the best cnc router ever
01:38 PM roycroft: the drawback being that it will never be built, as the design would never be finished
01:40 PM Rab: Stiff competition, though.
01:45 PM roycroft: heh heh. he said 'stiff'
01:45 PM roycroft: that's my best beavis imitation
01:46 PM JT-Woodshop: I need a good compass...
01:48 PM roycroft: jt-woodshop: i wanted to let you know
01:48 PM roycroft: blue spruce have some new card scrapers coming out, and they're on presale right now
01:48 PM roycroft: you might be interested, especially in the triangular ones
01:49 PM roycroft: those will be excellent for cleaning up glue on inside corners of joinery
01:49 PM roycroft: https://bluesprucetoolworks.com/products/triangular-and-extra-large-card-scrapers
01:49 PM roycroft: i just ordered both triangular ones and the 10" straight one
01:49 PM roycroft: their card scrapers are awesome - thicker and harder than most
02:03 PM JT-Woodshop: thanks
02:05 PM travis_farmer[m]: i can say in preliminary tests that the firmware works, as well as the sserial boards. however, my machine does nothing... i suspect i mis-wired something when i moved GPIO wires to match the new firmware. tomorrow i will verify that it is just a mis-wire by tracing every one, and adding a wire label (this time), so i know what it is and where it goes. only then can i rule out if the firmware truly works, and my re-wire failed.
02:05 PM travis_farmer[m]: symptoms are that the E-Stop is constantly triggered, so i suspect that i swapped it for something that is giving false signals.
02:08 PM travis_farmer[m]: makes me wish i labeled the wires from the start, rather than depend on a schematic that was out-dated
02:21 PM Tom_L: travis_farmer[m], you should do a chart like i did with wire colors to pins etc
02:22 PM unterhaus_: roycroft have you seen the union toolworks burnisher
02:22 PM unterhaus_: they also started making union planes again
02:22 PM travis_farmer[m]: i am thinking of something similar, Tom_L , just to be on the safe side next time.
02:27 PM unterhaus_: surgery was pretty interesting, the doc shot the laser at about 10 places in my eye
02:27 PM unterhaus_: disappointingly it didn't go "pew"
02:27 PM unterhaus_: more like "clink"
02:38 PM roycroft: i have another eye doctor appointment tomorrow
02:38 PM roycroft: when i was there last he indicated that my cataracts were mild, and i probably shouldn't have to worry about them for a while
02:38 PM roycroft: but my right eye correction is not good - i have worse vision in my right eye than my left
02:39 PM roycroft: there's a possibility that the cataract in my right eye is affecting that
02:39 PM roycroft: in which case i might need surgury on that eye
02:39 PM roycroft: and lasic wouldn't do it
02:39 PM roycroft: it would be a cataract replacement
02:41 PM unterhaus_: I had severe cataracts considering my age. I'm really happy with it
02:41 PM roycroft: is that was the procedure was for?
02:42 PM unterhaus_: 20% of people that have cataract surgery get scar tissue behind the lens. I was one of the lucky ones
02:43 PM Rab: The couple of older people I have known who got cataract surgery said it was amazing for them. Recovery is painful.
02:43 PM unterhaus_: yeah, the recovery from the initial cataract surgery didn't go that well for me, but after a month I was fine
02:44 PM unterhaus_: I have dry eyes anyway, so the suffering is real
02:44 PM unterhaus_: the worst part was all the eyedrops, I wish I had payed extra for the 1/day kind
02:44 PM unterhaus_: also, paid extra
02:45 PM roycroft: i finally have insurance that will cover most of the cost
02:45 PM roycroft: i'm lucky that i've not needed a procedure like that so far
02:45 PM unterhaus_: they usually cheap out on the eyedrops though
02:45 PM roycroft: but when i had my eye exam a few weeks ago, the doctor told me that on a scale of 1-5, my cataracts were about a 1.5
02:46 PM roycroft: and he said that when they get to 3.5-4, i'll want to seriously consider surgery
02:46 PM unterhaus_: the pharmacy didn't even ask if I wanted the expensive ones, they just substituted the cheap ones
02:46 PM unterhaus_: I suggest not waiting quite that long. I waited until there were some situations where I shouldn't have been driving
02:47 PM unterhaus_: mostly because I had trouble reading signs under difficult lighting
02:48 PM roycroft: well i'm going to see about it tomorrow
02:48 PM roycroft: since my right eye vision was not corrected properly
02:48 PM roycroft: either he got the rx wrong, or the cataract is interfering
02:48 PM unterhaus_: you had lasic that didn't work?
02:48 PM roycroft: if the latter, we'll be talking about doing one eye soon
02:48 PM roycroft: no, not lasic
02:49 PM roycroft: i just had a regular eye exam and a new eyeglass prescription
02:49 PM roycroft: but now my left eye vision is 20/15 (which is what both eyes have been correcting to every since i started wearing glasses), and my right eye is 20/30
02:49 PM unterhaus_: my glasses from before cataract surgery work perfectly as reading glasses now
02:50 PM roycroft: i have astigmatism, which is my main vision impairment
02:50 PM roycroft: i don't know if i would get an iol that corrects for that or not if i get the surgery
02:50 PM roycroft: if it did, that would be interesting
02:50 PM roycroft: i'd love to have 20/20 or 20/15 distance vision uncorrected
02:51 PM roycroft: i've been wearing glasses for the astigmatism since i was 16
02:51 PM unterhaus_: yeah, I can read the bottom line on the eye chart for the first time in decades
02:51 PM roycroft: it would be so nice to just have to wear reading glasses, and safety glasses in the shop
02:51 PM Tom_L: they were glass back then too :)
02:51 PM unterhaus_: it's a weird feeling
02:51 PM roycroft: yes
02:51 PM roycroft: and the lenses i just got are plastic
02:52 PM roycroft: for the first time - i was able to get glass lenses until now, for an extra fee
02:52 PM Tom_L: doubt you can even get glass now
02:52 PM roycroft: but now they can't even get them
02:52 PM XXCoder: theres cheap glasses websites wonder if they have glass
02:52 PM XXCoder: https://www.zennioptical.com/ for example
02:52 PM XXCoder: btw great to have cheap backups
02:53 PM unterhaus_: they gave me this sheet of restrictions today that uses a lot of words to say "no restrictions"
02:58 PM unterhaus_: if you said "okay google play barry manilow" in a meeting, how many phones would start playing barry manilow?
02:59 PM XXCoder: lol
03:00 PM XXCoder: theres applicable dilbert comic
03:04 PM roycroft: scarring can often be fixed by an additional surgery, btw
03:05 PM Tom_L: cause i sure wanna do it twice
03:06 PM roycroft: once is enough, if it works
03:06 PM roycroft: i'd rather do it twice than live with poor results after the first go
03:10 PM XXCoder: my mom had contracts surgery
03:10 PM XXCoder: she has 2 artifical ones now
03:10 PM XXCoder: the lens thing
03:11 PM XXCoder: it was bit scary for me, worrying about her lol eye surgery
03:13 PM roycroft: it concerns me too
03:14 PM roycroft: and that's a big reason only one eye is done at a time
03:14 PM XXCoder: yeah same for mom
03:14 PM roycroft: but even if i lost or had diminished vision in one eye i'd be very unhappy
03:14 PM XXCoder: keep in mind that for deaf person, vision is really vital
03:14 PM roycroft: but with cataracts, you lose vision anyway
03:14 PM roycroft: it's a matter of slowly losing it over time, or risking losing it all at once
03:18 PM unterhaus_: yeah, the thing about cataracts is you have bad vision but glasses can't fix it
03:18 PM XXCoder: yeah
03:22 PM CaptHindsight[m]: https://forum.linuxcnc.org/media/kunena/attachments/31446/1hrtest.jpeg Orangepi5
03:22 PM XXCoder: 8 us? isnt that way better than 25k or so?
03:22 PM CaptHindsight[m]: well beyond adequate for Mesa or Remora
03:23 PM XXCoder: or am I misreading
03:23 PM CaptHindsight[m]: it's a servo thread
03:23 PM CaptHindsight[m]: I repeat SERVO thread jitter
03:23 PM XXCoder: oh
03:24 PM CaptHindsight[m]: the guy that tested this on the forums keeps getting base vs servo threads confused
03:25 PM CaptHindsight[m]: so way more than good enough SERVO thread jitter
03:25 PM CaptHindsight[m]: https://forum.linuxcnc.org/18-computer/48079-can-the-opi5-be-configured-to-run-lcnc IF interested
03:27 PM unterhaus_: I usually get base and servo thread mixed up
03:30 PM CaptHindsight[m]: hardly anyone uses a Base thread with LCNC anymore since it mostly for software stegens with an LPT port
03:30 PM unterhaus_: it works better than idle = poll though
03:30 PM unterhaus_: on my rpi anyway
03:31 PM CaptHindsight[m]: unterhaus_: what works better than "idle = poll"?
03:31 PM unterhaus_: having a base thread wakes up the processor and reduces the latency experienced by the servo thread
03:31 PM CaptHindsight[m]: the bots drop messages at time, I don't follow you
03:32 PM CaptHindsight[m]: ah
03:32 PM unterhaus_: it seems, anyway
03:33 PM CaptHindsight[m]: well with Rpi's you have you work around their firmware limitations
03:33 PM CaptHindsight[m]: so it might be a hacky fix that works well enough
03:33 PM unterhaus_: it might be worth a shot sometimes
03:35 PM unterhaus_: I messed up my interwebs hooking up my mesa card
03:36 PM unterhaus_: how many glxgears == 1 celine dion youtube?
03:40 PM XXCoder: https://youtu.be/A33Y3XbCjXM very nice freecad video
03:40 PM unterhaus_: it works the same on my pc. with base thread, servo thread latency is 1.6microseconds
03:40 PM unterhaus_: without base thread it's almost 6microseconds
03:45 PM CaptHindsight[m]: unterhaus_: I'm sorry but celine dion youtube's break my ability to monitor test results
03:46 PM unterhaus_: that's why it's good there are no speakers on the lcnc computer
03:46 PM unterhaus_: hopefully they won't figure out it's me
03:52 PM pere: hi
04:02 PM roycroft: it seems the cnc machine would drown out any sound coming from the cnc computer, so there's really no point in having speakers anyway
04:03 PM XXCoder: just play heavy metal music from it as addon to cnc noises
04:05 PM roycroft: wow
04:05 PM roycroft: i was cleaning out a desk drawer, looking for something, and i found a bundle of $20 bills in it
04:06 PM * roycroft wonders where that came from
04:06 PM * roycroft should look for stuff more often
04:42 PM perry_j1987: so glad you found my stack roycroft
04:43 PM perry_j1987: been lookin for that
04:56 PM travis_farmer[m]: Pizza (hamburger) for supper tonight :-)
04:58 PM roycroft: finders keepers
04:58 PM roycroft: i have to go check in ballots tonight
04:59 PM roycroft: but the work party starts at dinner time, so i'll get some good oaxacan food for everyone at the local taco truck, and expense it
05:11 PM XXCoder: dont forget to send some to me
05:12 PM CaptHindsight[m]: i used to ask for local foods when friends would ask me what to bring back from a trip
05:13 PM CaptHindsight[m]: they never did, and always with some excuse
05:13 PM CaptHindsight[m]: "the hotdog would have been two days old and in a carry on"
05:13 PM CaptHindsight[m]: i never said i was going to eat it
05:18 PM XXCoder: lol
05:27 PM unterhaus_: i worked with a guy who had a whole collection of mumified fruit in his desk
05:28 PM unterhaus_: whenever someone left some fruit in their desk until it totally dried out they would give it to him
05:31 PM CaptHindsight[m]: also sounds like mold fungus collection
05:34 PM XXCoder: and rasins
05:44 PM unterhaus_: In Utah, fungus doesn't grow because it needs more water
05:44 PM unterhaus_: I'm just making that up
08:16 PM unterhaus_: I had to listen to the free cad academy guy say "holy line" 4 times before I realized he was saying polyline
08:17 PM XXCoder: lol
08:17 PM XXCoder: reminds me of that history class in college
08:17 PM XXCoder: interpeter kept saying "black paper"
08:17 PM XXCoder: teacher was indian an very strong accent
08:18 PM XXCoder: turns out its black pepper
08:28 PM unterhaus_: the worst thing my advisor mispronounces is "birth and death" -- "bart and det"
08:30 PM unterhaus_: usually I'm pretty good at accents, but there was no context that would lead me to understanding what he was talking about
08:31 PM XXCoder: https://upload.wikimedia.org/wikipedia/en/a/aa/Bart_Simpson_200px.png
08:31 PM XXCoder: ;)
08:32 PM XXCoder: with his friend https://www.nicepng.com/png/detail/46-469735_det-twinkie-boi-twinkie-character.png
08:33 PM XXCoder: det twinkie boi :P
08:33 PM XXCoder: joking aside, I bet accents can get real annoying
08:33 PM XXCoder: there is such thing for ASL, but its fairly rare
08:34 PM piranha32[m]: my biggest fear is getting "beach" understood as "bitch"
08:35 PM piranha32[m]: pronouncing "FAQ" is also tricky
08:35 PM unterhaus_: I saw a person teaching french where their example of people mispronouncing things was "vin" and "vent"
08:36 PM unterhaus_: I thought it was pretty goofy because I don't think people usually order a glass of wind
08:38 PM XXCoder: fun
08:42 PM unterhaus_: I grew up in a college town in deepest darkest appalachia, so most accents don't phase me much
08:42 PM unterhaus_: holyline notwithstanding
09:02 PM _unreal_: first test print went well
09:02 PM _unreal_: its nice to have a much larger 3d printer now
09:45 PM Lcvette[m]: JT-Cave: not sure if this is part of the same issue, but for some reason even when selecting an existing firmware such as 7i92_7i77_7i76d.bit, it only allows selection of one daughter card, i assumed this would be because the other defaulted to the second card on firmware, but it does not appear anywhere further down the line in the config builder.
09:46 PM skunkworks: https://forums.raspberrypi.com/viewtopic.php?p=2079739
09:46 PM skunkworks: kinda looks like even with bookworm - we will have to keep building a rpi image.
11:17 PM * roycroft is installing ubuntu tonight, something he doesn't often do
