12:11 AM roycroft: in my writing classes i was taught to always spell out an abbeviation or acronym the first time in any document, and then it was ok to use the abbreviation or acronym after that
12:19 AM roycroft: i've always done that
12:19 AM roycroft: one should never make assumptions about the background of the reader
12:31 AM pere: seb_kuzminsky: any luck regaining control over the openhub pages for linuxcnc, <URL: https://www.openhub.net/p/linuxcnc >? I just noticed it is flagged as a duplicate of emc, and just added a similar flag for linuxcnc-mirror, <URL: https://www.openhub.net/p/linuxcnc-mirror >.

05:17 AM JT-Cave: morning
06:32 AM t4nk_freenode: morning
06:33 AM XXCoder: hey
06:33 AM t4nk_freenode: I'm a little bit ticked off; been trying to mill some plastic
06:33 AM t4nk_freenode: clear plastic, hard, don't know what it is exactly
06:33 AM t4nk_freenode: had trouble fixing it down to my bed
06:34 AM XXCoder: is it a termosplastic?
06:34 AM XXCoder: those is notiously hard to mill
06:34 AM t4nk_freenode: think I have speeds and feeds right atm
06:34 AM XXCoder: needs tons of coolant
06:34 AM XXCoder: and short cuts to prevent overheatibng
06:35 AM t4nk_freenode: but what struck me most is that the dimensions were off, noticeably more than with mdf
06:35 AM t4nk_freenode: is that because it's harder than mdf?
06:35 AM t4nk_freenode: it's very thin though
06:36 AM t4nk_freenode: 1.5mm, I'm taking cuts of .5mm deep
06:36 AM XXCoder: could be backlash. not sure what machine yioure cutting with
06:36 AM t4nk_freenode: got it taped down with double sided carpet tape now, that seemed to work
06:38 AM t4nk_freenode: hadn't used my machine since I messed around drilling the holes into the bolts a while ago
06:38 AM t4nk_freenode: but at some point... the bolt got a bit loose when I was drilling, and then the drill broke through the side
06:38 AM t4nk_freenode: and the machine went crazy going in circles around the bolt
06:39 AM t4nk_freenode: spindle and carriage were forced along
06:39 AM XXCoder: id suggest give your machine a checkover
06:39 AM t4nk_freenode: guess that can't be too great
06:39 AM t4nk_freenode: indeed, that's a good idea
06:39 AM XXCoder: tighten bolts, etc
06:39 AM XXCoder: test orthogical or not so on
06:39 AM XXCoder: head could be not 90 to surface for example
06:40 AM t4nk_freenode: it won't be long now before I order some alu beams to build something better
06:43 AM XXCoder: nice
06:51 AM t4nk_freenode: https://www.action.com/globalassets/cmsarticleimages/34/59/2529028_4049793025124_102.png?preset=mediaSliderImageZoomed this is the stuff
06:52 AM t4nk_freenode: hehe, maybe you can understand me being ticked off... I had to hacksaw through it to get some millable stock
06:53 AM XXCoder: looks like some printer hopper
06:55 AM t4nk_freenode: I had one run, after which there was a Huge lump of plastic fused to the flute
06:55 AM t4nk_freenode: that was probably too much rpm
06:55 AM XXCoder: yep termosplastics like to do that
06:55 AM XXCoder: it got too hot
06:56 AM XXCoder: i used to run fucking nylon
06:56 AM XXCoder: machine have to heavily spray coolant into nylon to keep it cool
06:56 AM XXCoder: if youre not sure, yes, I hated running nylon
06:57 AM t4nk_freenode: my mostly mdf machine would double in size if I watered it too much ;)
06:58 AM XXCoder: you would need alum machine with proper bin and recycling bin for coolant
06:58 AM t4nk_freenode: I saw a youtube today, there was sooo much liquid running
06:58 AM t4nk_freenode: well, let's have another crack at it
06:59 AM XXCoder: change it to do brief cuts and move to other places for milling, and for drilling, peck cycle
07:33 AM Tom_L: hi
07:33 AM XXCoder: yo
07:53 AM mrec: did anyone ever work with a 1mm endmill?
07:54 AM XXCoder: smallest I ever used was 1/16 in
07:54 AM XXCoder: actually, 1/32
07:54 AM XXCoder: that one was weird
07:55 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/etching/mills1.jpg
07:55 AM XXCoder: unfortunate though since I dont do cam, just use programs made by others
08:06 AM t4nk_freenode: brr, that took a while to clean up.. that's some nasty stuff, plastic pieces won't vacuum off your clothes
08:07 AM CloudEvil: That depends, some are made orders of magnitude easier by just spritzing with water.
08:14 AM XXCoder: mdf framework, water arent good
08:16 AM t4nk_freenode: came out nice after all though
08:17 AM t4nk_freenode: I went down on the rpms
08:17 AM t4nk_freenode: another learning experience
08:17 AM XXCoder: nice
08:17 AM XXCoder: yeah i guess that cut rubbing and heat
08:18 AM t4nk_freenode: set at 600mm/min feed
08:21 AM CloudEvil: XXCoder: clothes, I mean
08:22 AM XXCoder: oh!
08:22 AM XXCoder: kills static

11:11 AM aaroncnc: any one here familiar with creating deb packages?
11:14 AM JT-Cave: aye
11:18 AM aaroncnc: JT-Cave, so i have built VTK from source for a rpi 64bit with QT5 python2.7 and opengl. i made it with Cmake and installed it. so now probe basic works. I wanted to save other the trouble of having to do the same if they wanted to use a 64bit version and still use probebasic. So i wanted to create a deb package.
11:19 AM aaroncnc: Any advice on a good place to start reading and a good tool to package this up?
11:21 AM JT-Cave: my tutorial comes to mind :) https://github.com/jethornton/simple-pyqt5-deb
11:21 AM roycroft: are you wanting just the package to extract on an already-installed pi, or do you want an installable image that has the os with real-time kernel as well as your package?
11:25 AM roycroft: sorry, disconnected for a moment
11:27 AM aaroncnc: roycroft, first just the package then i am going to start with a fresh 64bit image that i have not touched and install my file then i was hopefully going to create a entire image. so a user could just download my image and have everything setup.
11:28 AM roycroft: i've started working with arm-img-builder, which will take an installation on a pi and package it into an installable image
11:29 AM roycroft: the tool is a bit rough around the edges at this point, but it is usable, and the developers are responsive and active
11:29 AM roycroft: https://github.com/pyavitz/arm-img-builder
11:30 AM roycroft: it also lets you cross-compile on a more capable computer than a pi
11:30 AM roycroft: which definitely speeds builds up
11:30 AM JT-Cave: I've not had time to look at it close or figure out where to start lol
11:30 AM roycroft: i've built a kernel with it on a development machine
11:31 AM roycroft: but i haven't had time to build an entire os/image with it yet
11:31 AM roycroft: this is bod election week at the country fair, and i'm pretty busy dealing with checking in ballots, and getting ready for the ballot count on sunday
11:32 AM roycroft: so my evenings have been pretty busy
11:32 AM JT-Cave: ok, I'll try and get a start on it tomorrow... lunch minute is up so back to work for me
11:33 AM roycroft: the tool is geared towards ubuntu now, because one of the developers likes having a bunch of different compliers available, but i've made it work on debian
11:33 AM roycroft: i see no point in having gcc8, gcc9, and gcc10 all on the same machine
11:33 AM roycroft: and ubuntu is irritating beyond my level of tolerence
11:34 AM roycroft: if you are going to do a debian install let me know and i'll send you the depencencies that i installed to get it working
11:34 AM roycroft: make ccompile will not work on debian
11:35 AM t4nk_freenode: * Searching for gcc ...[I-O] [ ] cross-arm-none-eabi/gcc-11.2.0:11 [IP-] [ ] sys-devel/gcc-10.3.0-r2:10 [IP-] [ ] sys-devel/gcc-11.2.0:11
11:35 AM t4nk_freenode: :b
11:35 AM t4nk_freenode: gnight all..\
11:36 AM roycroft: i remember when gcc was posted in comp.sources.unix, and it would take the better part of a day to build the compiler, which involved multiple bootstrap builds
11:37 AM roycroft: on a "fast" 486 with oodles (4MB) of ram
11:38 AM roycroft: it's not as onerous now, but i still don't see the point of having a bunch of compilers on a machine when one will do
11:39 AM aaroncnc: so i am still new to linux and i know that i dont know enough but i am trying anyways. Reading JTs guide did little to help. but im sure its me lacking some basic understandings.
11:39 AM roycroft: but it's not my tool, and i've made it work on debian
11:39 AM roycroft: this particular developer who moved to ubuntu prefers debian to ubuntu himself, but still wanted to have all the compilers, so he moved the tool platform
11:42 AM pere: roycroft: one advantage of having several compilers is that they detect and report different bugs, problems and weaknesses in the code, so building with several compilers and fixing the issues they report can improve the code quality.
11:42 AM pere: for example, clang is a lot better than gcc, in my view, at reporting issues with c++ templates. :)
11:43 AM JT-Shop: aaroncnc, make a small test deb using my tutorial
11:58 AM roycroft: the image builder tool is not a development tool
11:58 AM roycroft: it's a packaging tool
11:58 AM solarwind: So Tier 4 deisel engines keep advertising "cleaner than air"
11:58 AM roycroft: i mean, it does do kernel builds, when necessary, but it is primarily designed as a packaging tool
11:58 AM solarwind: Does that mean I can run them indoors?
11:59 AM roycroft: and debugging should be completed before packaging
11:59 AM solarwind: With the window open or something that is
12:01 PM roycroft: the chemical reaction in an internal combustion engine produces co2 and water
12:01 PM solarwind: THat's the ideal reaction for any combustion
12:01 PM roycroft: "cleaner than air" i should assume means a fairly pure reaction, with no other pollutants than the co2
12:01 PM solarwind: But the byproducts as always are the issue
12:01 PM roycroft: but it certainly does not mean 'no co2 produced'
12:02 PM roycroft: i don't think i'd want my shop filling up with co2, regardless of whether it's pure co2 or pollution-laden co2
12:02 PM solarwind: CO2 is not my concern, it's CO and NOx and particulate matter
12:02 PM roycroft: co2 matters if you're trying to breathe
12:02 PM solarwind: CO2 is a non issue and easy to vent
12:02 PM solarwind: The difference in partial pressures of CO2 means it'll equalize with the outside with the window open
12:03 PM roycroft: i think it's more akin to running something like a propane-powered forklift
12:03 PM solarwind: Yeah how does it compare to a propane engine?
12:03 PM roycroft: it won't kill you, but you still need ventilation
12:04 PM solarwind: Those don't have particulate filters and exhaust scrubbing, etc.
12:04 PM roycroft: even if it's running in an indoor space that is unoccupied, you would eventually use up all the oxygen in the air and the engine wuld die
12:04 PM solarwind: Gas exchange due to partial pressure differences is very strong. Just need a bit of ventilation
12:05 PM roycroft: if i were running a stationary internal combustion engine in an indoor setting i'd duct the air inlet and exhaust to the outside
12:05 PM solarwind: Actually just the exhaust should be fine
12:05 PM roycroft: propane forklifts can be used in warehouses because they open big doors in them and there is plenty of outside air exchange
12:06 PM roycroft: if you want to operate a forklift in yellowknife this time of year, best to use an electric one so you can keep the doors shut
02:16 PM CaptHindsight[m]: aaroncnc: try asking in #debian about building packages
02:17 PM CaptHindsight[m]: deb packaging has a tradition of being more complex than other distros
02:21 PM CaptHindsight[m]: solarwind: is that why all the water parks in Yellow Knife close by mid August?
02:21 PM CaptHindsight[m]: or do moose tend to get stuck in the tubes?
02:33 PM aaroncnc: CaptHindsight[m], crossing my fingers its building my package now
02:37 PM aaroncnc: it built a package
02:37 PM aaroncnc: it only took me 3+ hours now to see if it will work.....
02:39 PM aaroncnc: well it installed with no errors.
02:52 PM JT-Shop: awesome
03:04 PM * roycroft wonders if yellowknife has ever been mentioned twice in the same day on irc before
03:04 PM roycroft: or anywhere else in the universe, for that matter
03:44 PM CaptHindsight[m]: nice street views of Yellowknife on Google
03:47 PM CaptHindsight[m]: https://goo.gl/maps/akcJyjBSiJNYisvg6
03:48 PM roycroft: that's a pretty big snow machine there

05:03 PM roycroft: a nicely made motor mounting plate just arrived for my mill, and it fits perfectly
05:08 PM Tom_L: i'd expect no less from that guy
05:08 PM Tom_L: i've heard rumors that he knows his shit
05:11 PM roycroft: i wasn't concerned about it at all
05:11 PM roycroft: but thought i'd mention it nevertheless
05:12 PM roycroft: tje
05:12 PM roycroft: ack
05:13 PM roycroft: the "fits perfectly" part is more a reflection of the measurer and drawing generator than the maker
05:13 PM roycroft: there was no doubt in my mind that the part would meet the specifications in the submitted drawing perfectly
05:30 PM roycroft: i was just browsing for pizza recipes, as i'm in a mood to make something different tonight, and read an article that said that "classic" pizza comes from italy and is made of a leavened bread crust, tomatos, and cheese, and dates back to the 10th century
05:30 PM roycroft: which i found rather interesting, as tomatos are indigenous to central and south america, and were first brought to europe by the spanish in the early 16th century
05:31 PM roycroft: did the italians discover the new world before the vikings did?
05:48 PM JT-Shop: interesting
05:49 PM JT-Shop: maybe a time warp?
05:50 PM JT-Shop: I think it's a combination of the measuring and drawing fellow and the making fellow
05:51 PM JT-Shop: making this crust tomorrow I think... https://www.kingarthurbaking.com/recipes/thin-crust-pizza-recipe
05:56 PM _unreal_: sup
05:56 PM _unreal_: you guys hear about alec baldwin
05:58 PM _unreal_: hello?
06:00 PM roycroft: yes, i think most of the world have heard about him
06:00 PM roycroft: that was a tragic incident
06:00 PM roycroft: i have other challenges ahead of me now with the mill, but having that mounting plate makes the rest possible
06:01 PM roycroft: i thought the timing pulleys had set screws, and the original ones i was looking at certainly did, but these do not
06:01 PM _unreal_: what is the tension method then?
06:01 PM roycroft: and the collar is too small for set screws, i think, so i'm going to have to make some collars for the motor shaft to hold the motor pulley in place
06:02 PM XXCoder: roy think there was native ones, just that it was thought as poison by europeons
06:02 PM roycroft: and i guess i'll have to broach those collars as well
06:03 PM roycroft: you're correct that they were thought of as poisonous, as they are in the nightshade family
06:03 PM XXCoder: apparently due to tomotoes acidity etching lead off fork etc and leaching lead out
06:03 PM roycroft: but they are not native to italy
06:03 PM roycroft: when early spanish explorers first brought them back to europe botanists considered them poisonous and did not try eating them
06:04 PM XXCoder: https://aggie-horticulture.tamu.edu/archives/parsons/publications/vegetabletravelers/tomato.html
06:04 PM roycroft: the first mention of tomatos in italian cuisine dates from the mid-16th century
06:05 PM XXCoder: makes sense, there was already some visits then
06:06 PM XXCoder: in usa, first records is 1781
06:06 PM roycroft: that article confirms what i just said, other than a suggestion that native americans may have brought tomatos with them from, i presume, asia
06:07 PM roycroft: oh, no, i misread it
06:07 PM roycroft: they're talking about native americans cultivating them from the wild ones in south america
06:07 PM XXCoder: yeah
06:08 PM XXCoder: well you got more right than I did so its fine lol
06:08 PM roycroft: this is not the first time i've run into persons or writings that claim that tomatos originated in italy
06:09 PM roycroft: if you don't know the history, i suppose it's a reasonable assumption
06:09 PM roycroft: it just happens to be completely wrong
06:09 PM infornography: fascinating
06:10 PM XXCoder: on east side, it'd appear like it, italians suddenly having tomotoes everywhere
06:10 PM roycroft: i do take issue what that article's statement that "spaghetti would hardly be spaghetti without tomatos"
06:10 PM XXCoder: american view it basically is
06:10 PM roycroft: as i use a tomato-based sauce when i make spaghetti probably less than half the time
06:10 PM XXCoder: but yeah
06:11 PM XXCoder: ugh I want spaghetti
06:11 PM XXCoder: too much carbs
06:12 PM roycroft: one of my favorite quick spaghetti dinners is mushrooms, artichoke hearts, and onions cooked in olive oil and lemon juice, tossed with the noodles, and topped with fresh parmigiano reggiano
06:13 PM XXCoder: i guess you use some sort of oil for noddles itself?
06:14 PM roycroft: the olive oil and lemon juice are the "sauce"
06:15 PM XXCoder: not bad. i do like olive oil
06:15 PM roycroft: i add herbs and garlic to it, of course
06:15 PM _unreal_: you likaaa dee sauce?
06:15 PM XXCoder: I literally drink it. in keto chow mix lol
06:15 PM roycroft: olive oil is my primary cooking oil
06:16 PM roycroft: it looks like that monster storm that's going to hit northern california will miss us, thank goodness
06:16 PM XXCoder: certainly rainy here
06:16 PM roycroft: we'll get a lot of rain this weekend, but no hurricane-force winds like sacramento is supposed to get
06:16 PM XXCoder: good thing
06:17 PM roycroft: actually, there is a wind advisory for here
06:17 PM roycroft: 65km/h gusts through tomorrow night
06:18 PM roycroft: oh, sorry
06:18 PM roycroft: sunday night
06:18 PM roycroft: i guess that will be what's left of what will hit northern california
06:19 PM roycroft: the winter forecast is out now
06:19 PM roycroft: most of the country will be warmer and drier this winter than usual
06:19 PM roycroft: but the pacific northwet and parts of the rockies will be cooler and wetter than usual
06:20 PM roycroft: a typical la niña pattern
06:21 PM * roycroft thinks it's time to get his lathe back online - he finally got the power cord built for it, and needs it to make parts for his mill
06:22 PM XXCoder: roy did you see that video where guy makes lathe with just basic tools, and very few bought parts
06:22 PM XXCoder: think you did actually
07:24 PM Tom_L: haha gecko finally replied
07:24 PM Tom_L: no problem powering a driver with no motor attached

10:14 PM solarwind: Is it normal for my BBQ propane tank to have oily deposits in the connector? I use it for my high output propane torches
10:14 PM solarwind: I'm guessing it's just long chain hydrocarbon impurities in the propane settling inside the hoses and connectors
10:31 PM mrec: does anyone have a fiber laser?
10:32 PM roycroft: i manage lots of fiber that is lit with lasers
