01:24 AM solarwind: BTU is such a retarded unit
01:36 AM solarwind: just WHY. What's wrong with Joules or watt·h?
01:36 AM solarwind: not only that, _nobody_ uses it correctly
01:36 AM solarwind: what the FUCK is a 100,000 BTU heater?
02:15 AM Deejay: moin
02:15 AM Deejay: merry christmas
02:40 AM solarwind: Turns out our natural gas prices are insanely low, $0.14/m^3
02:40 AM solarwind: a cubic metre contains about as much energy as a litre of Diesel fuel
02:40 AM solarwind: 10.345 kW·h thermal energy
02:41 AM solarwind: whoops, it's actually $0.014
02:41 AM solarwind: so about 2 cents
02:42 AM solarwind: scratch that, sleep meds kicking in
02:42 AM solarwind: I was right the first time
02:43 AM solarwind: that works out to ~$0.014/kW·h
02:43 AM solarwind: Which means it's cheaper to run a generator for electricity than to pay the electricity company
02:48 AM solarwind: Propane is also pretty cheap, about half the cost of diesel for the same energy, and 1/4 the cost of diesel if you fill it up from the automotive propane pump
02:49 AM solarwind: Need to figure out how to get a tank that I can legally fill using that vehicle fill up station
03:32 AM NoSpark: solarwind: BTU vs Tons , yes Tons is apparently a US unit of thermal transfer
03:33 AM NoSpark: bot sure which one I hate more
03:35 AM NoSpark: solarwind: I worked out a couple of years ago that it would be cheaper to run a deisel generator, even with paying about 70c per liter road tax, than paying the current rate of 24c per Kwh for electricity
03:56 AM NoSpark: add a cheap solar power system to take some of the AC load for the hot days (Australia.... right?) and it makes even more difference
05:03 AM Tom_L: Merry Christmas
05:08 AM JT-Cave: Merry Christmas
05:11 AM Tom_L: 32°F High 35°F
05:57 AM JT-Cave: 57°F Rain High: 60°F⇓
06:41 AM lcnc-relay: <travis_farmer (@_discord_731083529441640538:jauriarts.org)> Merry Christmas
07:10 AM JT-Cave: rooster just crowed and it's stopped raining
07:15 AM JT-Cave: I take that back it's still raining
09:51 AM t4nk_freenode is now known as t4nk_fn
10:48 AM JT-Shop: nap time
12:17 PM Roguish: good morning. Happy Holidaze.
12:40 PM solarwind: My cat's fur absorbs the IR heat from my 10kW patio heaters (which I use indoors)
12:41 PM solarwind: hopefully it doesn't damage the fur
12:41 PM solarwind: it's hot to the touch :/
12:45 PM XXCoder: solarwind: https://scienceandink.com/screen_res/nz199.jpg
12:53 PM solarwind: Yeah she seems to like the heat, should be fine
01:11 PM Unterhaus_ is now known as Unterhausen
01:11 PM Unterhausen: the drama on bambu labs social media today is extra special
01:18 PM Unterhausen: among other things, they consider the whole printer to be a wear item not covered under warranty, so if it's broken when you get it they may say it's not covered
01:18 PM Unterhausen: but mostly a batch of newbies got them for christmas and they don't work
01:24 PM solarwind: LOL
01:24 PM solarwind: yup
01:24 PM solarwind: and the parts are impossibly to DIY/fix
01:28 PM solarwind: You guys reminded me, I _just_ bought the FLSUN V400
01:28 PM solarwind: like 2 minutes ago
01:39 PM Unterhausen: I was tempted to get one, but there's too much drama for me
01:39 PM Unterhausen: the bambu, that is
01:39 PM solarwind: FLSUN v400 uses kiipper out of the box
01:39 PM solarwind: fully serviceable and prints just as fast
01:40 PM Unterhausen: the university keeps selling dremel 3d printers for $300, I always figured it wasn't worth getting to mod
01:40 PM solarwind: also, delta mechanics are just really cool
01:40 PM solarwind: yeah don't bother, get one that uses real linear rails like the v400
01:40 PM Unterhausen: do you know if the motors on the v400 are on the top?
01:42 PM Unterhausen: my delta printer is currently in use holding up my caulk guns
01:42 PM solarwind: lol! why?
01:46 PM CaptHindsight: you need one of those CNC glue guns from Italy that have a ~5mm nozzle on a 5-axis system that also mills the parts to final form
01:48 PM CaptHindsight: https://en.machinetools.camozzi.com/products/additive-manufacturing/all-products/masterprint-5x-.kl
01:49 PM CaptHindsight: or a version to print composites https://en.machinetools.camozzi.com/products/composite-manufacturing/composite-manufacturing.kl
01:57 PM Unterhausen: I'm pretty happy with glue guns for the purposes I have for it. Mostly one-off fixturing
01:58 PM Unterhausen: One of the big japanese machine tool companies had a machine at IMTS that would do 5 axis milling and 3d printing
01:59 PM Unterhausen: Not sure I believe those two technologies are fully compatible
01:59 PM CaptHindsight: well faith based additive manufacturing is in its infancy
02:04 PM CaptHindsight: Friction Stir Welding (+) Machining on a 5-Axis CNC Milling Center https://youtu.be/hu3fyhMFwhY?si=06UnrGJj7iguRDiH&t=74
02:04 PM Unterhausen: the guys down the hall at work used to use welders for AM. Sold out to GE for $25 million
02:05 PM Unterhausen: their 3d printers didn't work, but they sold their solver, which apparently was quite fast
02:07 PM Unterhausen: I wanted to disappear their motion control stuff. Probably in a warehouse waiting for auction years later
02:09 PM CaptHindsight: sounds like software devs were working on hardware
02:10 PM solarwind: CaptHindsight bad idea lol, most software engineers are total idiots
02:10 PM lcnc-relay: <_veegee#0> solarwind _you're_ a total idiot
02:11 PM CaptHindsight: GE bought up a bunch of AM tech the past 10 years or so
02:11 PM solarwind: _veegee#0 shut up asshole, you are!
02:12 PM lcnc-relay: <_veegee#0> solarwind no you!
02:12 PM Unterhausen: they were all mechanical engineers, so totally unqualified
02:12 PM solarwind: _veegee you're ugly!
02:12 PM lcnc-relay: <_veegee#0> solarwind you're fat!
02:12 PM Unterhausen: I have to say that their prints looked good right up until they failed
02:13 PM solarwind: I have to fix this relay bot to properly tag on the discord side
02:13 PM CaptHindsight: why the prints failed?
02:15 PM solarwind: _veegee#0 loser
02:15 PM solarwind: yeah it's dropping messages sometimes...
02:15 PM CaptHindsight: looser
02:16 PM Unterhausen: they were doing things like building a single thickness wall. So they probably did difficult things on purpose
02:16 PM CaptHindsight: can you make the bot missssplell words randomly?
02:17 PM Unterhausen: but they would eventually fall over
02:17 PM solarwind: lol! yeah that's easy but they probably won't accept my pull request
02:17 PM Unterhausen: too bad you see the username as the relay instead of the username
02:17 PM solarwind: that's what I'm looking into
02:18 PM CaptHindsight: Deer Bot developers
02:19 PM Unterhausen: good luck, it's annoying
02:19 PM CaptHindsight: Matrix was great for about a year or two.
02:19 PM Unterhausen: matrix was good
02:19 PM CaptHindsight: Hardly anyone has a bridge anymore to libera
02:20 PM Unterhausen: what was wrong with matrix, some kind of security flaw?
02:20 PM solarwind: we really need a good decentralized protocol
02:21 PM solarwind: IRC is decent, but the limitations are annoying
02:23 PM solarwind: Unterhausen https://ca.store.flsun3d.com/products/flsun-s1
02:36 PM Unterhausen: I want to use servos on my delta, but I'm not dedicated enough to set up lcnc for it
02:36 PM solarwind: wtf there's a sign for ounce? ℥
02:37 PM solarwind: and we can't have signs for common units like meter and millimeter
02:38 PM CaptHindsight: m and mm are the signs
02:38 PM solarwind: yeah and so are "inch" and "foot" and "oz", but they get to pervert the " and ' and ℥ symbols
02:39 PM CaptHindsight: did Santa bring everyone good cheer?
02:39 PM solarwind: clearly not me
02:39 PM solarwind: all I wanted for christmas was for the US customary units to go away
02:59 PM CaptHindsight: rain all the rest of today here
03:57 PM Tom_L: solarwind, didn't work in the 70's, dunno why it would now
04:07 PM Tom_L: snow started
04:25 PM JT-Shop: lol
04:26 PM JT-Shop: hmm I have to take the hose off for tonight
04:27 PM Tom_L: stopped now. i think we're right on the edge of it
04:29 PM JT-Shop: cider brined chicken breasts, moms sweet potato pie and chicken gravy and corn
04:29 PM JT-Shop: smoked and glazed chicken breasts...
04:30 PM Tom_L: mmm
04:31 PM JT-Shop: very
04:31 PM JT-Shop: I need one of those culinary blow torches to crisp the skin
04:32 PM Tom_L: meh, just use one from the shop :)
04:32 PM JT-Shop: but I want to be cool like on guy's grocery games
04:34 PM Tom_L: guy's burgers on the ship were yummy
04:39 PM JT-Shop: I bet
04:43 PM JT-Shop: do you have a chicken guy near you?
04:44 PM Tom_L: not that i know of
04:44 PM Tom_L: there's every other kindof chicken place here
04:45 PM JT-Shop: https://chickenguy.com/locations/
04:48 PM Tom_L: krispy's, Strouds, Louisiana, Chicken Max, Popeyes, Slim-chicken, KFC... the list goes on
04:50 PM JT-Shop: back in the day in La Place we had KFC, Churches and Popeyes
04:51 PM JT-Shop: Al Copland opened the first Popeyes on Williams Blvd in Kenner La
04:51 PM JT-Shop: a tiny joint in a strip mall
04:52 PM JT-Shop: when he bought out Churches he lost his empire
04:53 PM JT-Shop: he always had a huge christmas display which caused huge traffic jams in his neighborhoo
04:58 PM Tom_L: years back we were flooded with pizza joints, now it seems to be chicken
04:58 PM Roguish: https://www.nytimes.com/interactive/2023/12/24/climate/groundwater-crisis-chicken-cheese.html
04:59 PM Tom_L: Chick-fil-a is big here and there is always a block long line in the drive thru
04:59 PM JT-Shop: they have one in Cape and they have a double drive up line
04:59 PM Tom_L: i doubt i could name them all if i had to...
04:59 PM Tom_L: same here on the double line
04:59 PM Roguish: I boycott chick-fil-a
05:00 PM Roguish: just like HobbyLobby.
05:00 PM JT-Shop: I've never been to one
05:00 PM JT-Shop: I do from time to time get something from hobby lobby
05:00 PM Roguish: far right evangelical racists
05:00 PM Tom_L: they're always busy
05:01 PM Roguish: here too. another one going in close by.
05:01 PM Tom_L: they don't push any of that on me when i go
05:01 PM JT-Shop: chick fil a?
05:01 PM Roguish: chick, that is. but we have a hobbylobbby too
05:01 PM Tom_L: yeah
05:02 PM Tom_L: both are closed sundays
05:02 PM JT-Shop: wish I could find a can of johnsons paste wax...
05:02 PM Tom_L: but i remember when nobody was open sundays
05:02 PM Roguish: https://www.vox.com/the-goods/2019/5/29/18644354/chick-fil-a-anti-gay-donations-homophobia-dan-cathy
05:03 PM Roguish: JT-Shop, how's the weather. media says there's a midwest blizzard
05:03 PM JT-Shop: not here
05:03 PM Tom_L: we're on the edge of it but i doubt we get much
05:03 PM Roguish: ok
05:04 PM JT-Shop: about time to tuck the hens in and read them a modified night before christmas story
05:04 PM Tom_L: last one few weeks ago was record breaking 7-8"
05:04 PM Roguish: is everyone havin' a good Holidaze?
05:04 PM Tom_L: relaxing
05:04 PM JT-Shop: yup
05:04 PM JT-Shop: gotta get an oil change this week
05:05 PM Roguish: just finished a quiet, slow and easy ride....
05:05 PM solarwind: Never mind, not torn anymore. Workstation class build it is.
05:05 PM solarwind: Just cannot survive without PCIe
05:05 PM JT-Shop: too wet here to ride the mountain bike
05:05 PM solarwind: wrong channel sorry
05:06 PM JT-Shop: yup
05:07 PM * JT-Shop wonders if he will stay awake to have a snifter of Remy Martin
05:07 PM Roguish: supposed to start raining tomorrow evening, for the week. figured I'd get out while I could. to fricking cold in the early morning.
05:08 PM Roguish: I've become a candy ass. won't ride in the wet, or below 55 degrees
05:08 PM solarwind: Roguish same here, I have full heated gear too
05:09 PM Roguish: i don'
05:09 PM JT-Shop: I used to ride the Bluewing at 40°F and sunny now it's 70°F and sunny
05:09 PM solarwind: and I Have the best wet tires you can get - Michelin Pilot Road 4
05:09 PM Roguish: i don't have heated gear, but lots of warm stuff to wear. just don't care
05:10 PM solarwind: I just like to lean hard and push hard and you can't do that in the rain
05:10 PM solarwind: I think I'm going to switch to Metzeler Roadtec 01
05:11 PM Roguish: i used to go out in the rain. tooooo old now.....
05:11 PM Roguish: 68 yesterday
05:11 PM JT-Shop: youngster...
05:12 PM Roguish: I'll take that from you JT-Shop
05:12 PM Roguish: it's cool.
05:13 PM JT-Shop: I can imagine while growing up having a birthday of 12/24 could suck
05:14 PM JT-Shop: going to get the second oil change this week I hope
05:14 PM Roguish: oh yeah, especially when you're a kid. no parties. gotta go to church...... better now, more friends remember
05:14 PM Roguish: JT-Shop, check this.... https://www.teslarati.com/spacex-starlink-internet-antacrtica-coldex-nsf-testing/
05:15 PM JT-Shop: I hope to never test that her
05:15 PM JT-Shop: e
05:18 PM Unterhausen: all of a sudden, it turns out I'm making dinner
05:19 PM XXCoder: JT-Shop: its worse when you have bad parents. my friend had birthday at dec 23rd. his parents used t give him gifts on that, then repackage it for xmas.
05:19 PM JT-Shop: yup that would suck
05:19 PM Roguish: yup. never had 'em repackaged, but definitely got 1 for 2
05:20 PM XXCoder: not evil parents or anything, never beat him and stuff but they didnt give him much love at all
05:20 PM JT-Shop: anyway time to retire for the night and tuck the hens in and read them a bed time story
05:20 PM Roguish: ciao dude.
05:20 PM XXCoder: have good reading
05:20 PM JT-Shop: say goodnight Gracie
06:01 PM Unterhausen: I'm done making dinner, but I'm not hungry
08:17 PM lcnc-relay: <andypugh#0> LinuxCNC 2.9.2 has been released
08:29 PM XXCoder: nice
08:30 PM -!- #linuxcnc mode set to +o by ChanServ
08:31 PM XXCoder changed topic of #linuxcnc to: LinuxCNC is a linux-based open-source CNC control. | Latest release: 2.9.2 | http://www.linuxcnc.org
08:31 PM -!- #linuxcnc mode set to -o by XXCoder
09:21 PM Tom_L: nice andypugh
09:51 PM solarwind: https://www.youtube.com/watch?v=mB_C8VdZ0r0 another burnishing tool, looks like a DIY build, looks really good
09:52 PM solarwind: Looks like it's just a sealed deep groove ball bearing rolling against a hardened ball of some kind held captive like in a ball point pen
09:53 PM XXCoder: interesting setup with bearing ball and wheel
09:53 PM solarwind: as soon as I pick up my 12L14 and brass stock that I ordered, I'm going to build one
09:53 PM solarwind: I have plenty of random hardened steel balls
09:56 PM solarwind: using a lathe center drill as a spot drill, shame shame
09:57 PM XXCoder: guy uses cutoff as chamfer tool
09:57 PM XXCoder: bit weird
09:58 PM solarwind: LOL yeah I was just about to say
09:58 PM Tom_L: did you find your center drill?
09:58 PM Tom_L: or get that cheap set
09:59 PM solarwind: Not exactly, but I got the 140° version of this: https://www.aliexpress.com/item/1005006332506345.html
09:59 PM solarwind: hopefully it does the trick
10:02 PM Tom_L: i had a carbide EM ground for a 45deg chamfer tool i also use for spots sometimes: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Vise_parts/Speedhandle2.jpg
10:02 PM Tom_L: works great for both actually
11:43 PM NoSpark: addf gm.0.read servo-thread -1
11:43 PM NoSpark: anyone know what the -1 after servo-thread does?
