03:59 AM travis_farmer: Morning :-)
04:23 AM Tom_L: 64°F hi 88°F
04:24 AM travis_farmer: 65F/88F
05:05 AM JT-Cave1: 72/88
05:05 AM JT-Cave1: 77 inside
05:06 AM travis_farmer: same here, too warm inside, and not enough breeze outside to cool the house down. had to kick the A/C on low
05:09 AM JT-Cave1: ac broken here
05:10 AM travis_farmer: oh, right... sorry
06:35 AM JT-Cave1: rooster just crowed
06:41 AM Guest4445: Hi, how to use wine? Gives exec format error
06:49 AM JT-Cave1: just sip wine slowly
07:10 AM travis_farmer: lol
07:28 AM * JT-Cave1 goes to start his chicken day
07:28 AM -!- #linuxcnc mode set to +v by ChanServ
09:33 AM JT-Cave: getting hot down here
09:37 AM skunkworks: raining here - cooling off. Finally
09:38 AM Scopeuk: not due to feel less than 25C here until tuesday
09:41 AM roycroft: 25 will be our high for the day
09:46 AM JT-Cave: it's a lot cooler upstairs with the air handler not running
09:46 AM skunkworks: The cooling has been much better since I replaced the bad cap.. I wonder how long it was struggling..
09:46 AM travis_farmer: make a swamp cooler
09:47 AM Scopeuk: getting to 28C feeling like 33 today, warmer tomorrow will also be probably 60 to 70% humidity
09:47 AM JT-Cave: swamp coolers only work in dry places and Swamp East Missouri is not dry
09:47 AM skunkworks: The heat we have had over the past few weeks has been pretty low humidity. So really - could have been worse..
09:47 AM skunkworks: normally it is pretty humid here.
09:48 AM roycroft: the humidity is really high here right now - about 90%, but it will drop down to <30% as the day progresses
09:48 AM roycroft: it's pretty typical this time of year
09:50 AM travis_farmer: holy crap that was fast! o ordered a couple 1/4" air flow valves (the needle valve things) yesterday. they shipped this morning, and are out for delivery today! apparently they are from Mass...
09:53 AM CaptHindsight: JT: did they say what was wrong with the evaporator coil they swapped out?
10:02 AM mrec: is it possible to update the FPGA image of the 7i96s via ethernet?
10:04 AM -!- #linuxcnc mode set to +v by ChanServ
10:05 AM JT-Shop: CaptHindsight, no, but there was no R22 left in the system
10:06 AM JT-Shop: mrec, yes, that is how you change the firmware
10:12 AM * JT-Shop goes to check on the AC guys
10:42 AM JT-Shop: CaptHindsight, I'm getting a whole new system
10:42 AM travis_farmer: 8-D
10:43 AM CaptHindsight: getting you off R22
10:43 AM CaptHindsight: the new stuff is 2x the efficiency
10:44 AM CaptHindsight: you power bill in the summer might drop by 30-40%
10:49 AM JT-Shop: yep no more R22 R410A I think
10:51 AM roycroft: the maga is weak in you
10:51 AM roycroft: you find new technology that is both cleaner and less expensive, yet you refuse to stubbornly stick to the old way
10:52 AM JT-Shop: once a year I get a letter to renew my domain networks account for $289
10:53 AM roycroft: oh brother
10:53 AM roycroft: that scam is still going on?
10:53 AM roycroft: they gave up on me years ago
10:53 AM JT-Shop: Description of services: annual website domain listing
10:53 AM roycroft: that reminds me
10:53 AM roycroft: yup, highlandwoodworking.com is still broken
10:54 AM roycroft: i'm glad i don't need a woodslicer blade right now
10:54 AM JT-Shop: I wish I had some monopoly money I would send it back postage due
10:54 AM roycroft: with a sheet of lead tucked inside the envelope?
10:54 AM JT-Shop: nice touch
10:56 AM JT-Shop: https://youtu.be/243oW7EDWzU?t=359
10:57 AM JT-Shop: I like that bosch saw it doesn't stick out the back
10:57 AM roycroft: i was interested in that saw, for the same reason
10:57 AM CaptHindsight: I started a new domain name and now I get tons of calls from India asking if I need web or business development.
10:57 AM roycroft: but the north american version does not have a laser guide
10:57 AM roycroft: and the european laser guide can't be added to it easily
10:58 AM JT-Shop: well that sucks
10:58 AM roycroft: the alternative is a festool kapex, for 3x the money
10:58 AM CaptHindsight: now you have to use a phone number for your DNS info where they can't bother you
10:58 AM roycroft: so no new chop saw for me
10:58 AM roycroft: capthindsight: i sell domains with privacy
10:58 AM roycroft: they won't get your info
10:59 AM roycroft: you are using the wrong registrar
10:59 AM roycroft: i bet you can get domain privacy from your registrar, for an extra fee
10:59 AM JT-Shop: I'm giving away one of my domains to a friend who want's to continue making Spyder stuff
11:00 AM * roycroft wonders why opensrs (his parent registrar) even offer the premium domain privacy feature now, because standard registrations come with it automatically
11:00 AM CaptHindsight: Key-Systems GmbH, oh crap they should have made it private
11:00 AM CaptHindsight: now i have to see why it's not
11:01 AM roycroft: you can always add that
11:01 AM roycroft: it won't stop what's leaked already, but it will stop future leaks
11:01 AM CaptHindsight: it was supposed to be private
11:01 AM CaptHindsight: maybe I unticked the box by mistake or similar
11:01 AM CaptHindsight: JFC the stupid calls we get
11:03 AM * roycroft wonders if vectric software will talk to him
11:03 AM roycroft: i'm still confused about what product i need for right now
11:04 AM roycroft: when i build the cnc router i know i'll need vcarve pro from day one
11:04 AM roycroft: and maybe aspire eventually
11:04 AM roycroft: but it looks like cut2d or cut2d pro might work for the shaper origin stuff
11:05 AM roycroft: i like that i can upgrade my license with no penalty, but i'm not excited about doing a bunch of upgrades
11:15 AM * JT-Shop needs to find a box for 7i95T's they will be here today
11:18 AM Loetmichel: ouch. Verdict from the Road leagal check is there.... Both front wheel drive shafts have to be new, one headlight has to be polished, the windshield water tank leaks and the parking brake is rusted... ~1200 eur :( (Thats what you get for forgetting TUEV for half a year :( )
11:19 AM JT-Shop: TUEV?
11:20 AM Loetmichel: german road legal check
11:20 AM Loetmichel: every two years. My sticker said: "Next in 03/23" :(
11:20 AM JT-Shop: opps
11:21 AM travis_farmer: i think i have a 21 or 22 sticker on my truck... :-(
11:22 AM Loetmichel: i was totally sure i bought that A-class with 2 years of TUEV. Was apparently only one year :(
11:23 AM JT-Shop: here in Missouri motor vehicles for the first ten years following the model year of manufacture and having less than 150,000 miles on the odometer are exempt from the safety inspection requirement.
11:25 AM Loetmichel: in germany every NEW car gets 3 years. then every two years after that.
11:26 AM CaptHindsight: no safety inspections are required for vehicles here, just emissions tests for '95 and newer
11:27 AM roycroft: we have a handful of counties in oregon that do emissions testing - mostly in the portland metro area, and one county in southern oregon
11:27 AM roycroft: other than that, we do not do any non-commercial vehile inspections
11:28 AM CaptHindsight: https://assets.rbl.ms/35065770/origin.jpg street legal
11:28 AM Loetmichel: roycroft: german highways have no speed limit on ~50% of the network. I feel a LOT safer if everyone has to have his car checked every two years. I dont want a car behind me at 140mph with no working brakes or a bad steering rack.
11:28 AM CaptHindsight: and i have seen worse on the road
11:35 AM JT-Shop: that's pretty bad
11:36 AM roycroft: i think it would be prudent for my state to do vehicle inspections
11:37 AM roycroft: but there would be so much opposition to that i don't see it happening any time soon
11:38 AM JT-Shop: Missouri now has a sensible plan for vehicle inspections
11:39 AM Scopeuk: having grown up somewhere with mandatory annual vehicle inspections it seams wild to me that places don't. there are so many people who can operate a vehicle but have no idea how to tell if it is in reasonable operating condition
11:39 AM Scopeuk: uk new cars get three years grace but everything else gets inspected anually
11:40 AM Scopeuk: I think there is some margin for classic vehicles over 40 or 50 years doing under a few hundred miles a year but I've not looked into the details in an age
11:40 AM roycroft: our drivers can't even aim their headlights properly
11:40 AM CaptHindsight: community awareness and reporting, you just shoot a rubber dart at the vehicle that drives recklessly, blows too much smoke, has access holes to rear suspension etc, and at the end of the day the police just stop the cars covered in rubber darts
11:40 AM roycroft: and headlights don't need to be aimed any more - they're factory-adjusted, and only the lamp itself needs replacing, not the entire housing
11:40 AM Scopeuk: Japanese police paintball cars they are interested in stopping, I guess the principal is the same
11:41 AM CaptHindsight: see it works
11:45 AM roycroft: maybe we should attach pink tutus to cars that appear to be in violation of safety standards
11:45 AM roycroft: that would be the appropriate way to flag them in this country
11:45 AM Loetmichel: roycroft: part of the german TUEV is to check headlight alignment. and you FAIL if its not alingled correclty.
11:47 AM roycroft: i fail to understand how headlights can become misaligned on modern vehicles
11:47 AM roycroft: it almost has to be done intentionally
11:48 AM roycroft: replacing the lamp does not affect alignment at all
11:48 AM travis_farmer: unreported car crash
11:48 AM Scopeuk: someone with the dexterity of a mop badly installs the cheapest supermarket lamp in the housing
11:48 AM skunkworks: The south main auto channel on youtube is fun to watch. He does real inspections (like won't just give a sticker) and shows what has been ok'ed by other shops.. It is scary
11:48 AM roycroft: a crash could do it, yes
11:48 AM skunkworks: (salt belt)
11:48 AM roycroft: but i see late model vehicles with headlights badly misaligned all the time that do not appear to have been involved in a crash
11:49 AM skunkworks: https://www.youtube.com/shorts/mgb5dGMc3jg
11:51 AM Scopeuk: a lot of vehicles also have adjustment for towing which can be missused by idiots
11:52 AM roycroft: yes, i can see that being a problem
11:53 AM roycroft: but when your left headlight points to the left and your right headlight points straight up that's not a towing adjustment issue
11:54 AM Scopeuk: yeh, that's got to be lamp loose in housing
12:09 PM Loetmichel: Scopeuk: a lot of modern cars (even my 2001 Opel Omega) had auto adjustment for rear load/towing.
12:09 PM Loetmichel: you could see the motors moving the beams up and down when starting the car.
12:10 PM roycroft: my f350 has really heavy springs, so it doesn't need much adustment
12:11 PM roycroft: it's not particularly comfortable to drive on rough roads, though
12:14 PM JT-Cave: I'm amazed at how smooth the C8 rides in touring mode and how stiff it is in track mode with almost no roll at all in any mode
12:15 PM JT-Cave: OnStar sent out a flat tire warning to C8's today and some of the warnings said tires low inflate to 480 pounds
12:17 PM Loetmichel: well, thats ~34 bar. probably the death of the tire.
12:17 PM Loetmichel: been there, done that accidentally (didnt knew the filler valve didnt show pressure while filling). was quite the bang :)
12:17 PM Loetmichel: (but i think the system only had 20 bar on it)
12:41 PM travis_farmer: i can picture 48 pounds, but 480 seems a tad exsessive ;-)
12:48 PM roycroft: 48psi is normal for my pickup, which i thought a bit odd, as i'm used to tires that inflate in the 32-38psi range
12:49 PM roycroft: but i guess the 12 ply tires can take a bit more pressure than the 6 ply tires
12:49 PM skunkworks: dad inflates his to like 70..
12:50 PM skunkworks: (350 iirc)
01:01 PM roycroft: that's more like bicycle tires
01:02 PM roycroft: and then there's lawn tractor tires which, while they can be rather large, are usually inflated to 10-12psi, so they don't put dents in the grass
01:02 PM skunkworks: right
01:12 PM roycroft: i think that the mowers used on golf course greens are inflated to more like 4psi, and they are super fat and perfectly smooth
01:12 PM * roycroft worked at a country club for a while when he was a lad
01:16 PM JT-Cave: normal services have been restored
01:17 PM JT-Cave: my road bike tires take 110 psi
01:23 PM JT-Shop: so I ended up with a 16 SEER compressor unit for the price of a 14 SEER
01:27 PM travis_farmer: :-D
01:41 PM CloudEvil: :)
01:49 PM Tom_L: JT-Shop, brand? fair chance it was made here
01:52 PM JT-Shop: Bryant
01:55 PM Tom_L: nope
01:55 PM Tom_L: that's carrier
01:56 PM JT-Shop: waiting on the basement to cool down to reinstall the water softener
01:56 PM Tom_L: they got the ac in yet?
01:57 PM JT-Shop: been running for 1/2 hour or so
01:57 PM Tom_L: nice
02:25 PM travis-farmer is now known as travis_farmer
02:25 PM travis_farmer: transformer blew... took out my internet... on my cell-phone hotspot...
02:59 PM travis-farmer: internet is back :-)
03:00 PM travis-farmer is now known as travis_farmer
03:07 PM roycroft: kyle must be busy today
03:08 PM travis_farmer: must be ;-)
03:51 PM roycroft: i'm really thinking that cut2d will work for me for now, and that i can upgrade to vcarve pro when i get my cnc router built
03:52 PM roycroft: and while i have the money for vcarve pro now, i'd rather have it collect interest for a while (now that i'm getting real, measureable interest) than give it all to vectric
04:10 PM _unreal_: ok getting ready to WIP out a little project box for my primary AC line filter with fuse for the new controller setup.
05:05 PM andypugh_: Nice looking new board (just been spammed by Mini-ITX.com: DC Power input and parallel port header. and 6W power consumptiion: https://www.mini-itx.com/~N100DC-ITX
05:07 PM bjorkintosh: https://en.wikipedia.org/wiki/A_Manufacturing_Language
05:12 PM andypugh_: LinuxCNC supports pluggable interpreters, you could persuade LinuxCNC to parse that.
05:13 PM bjorkintosh: really? that's incredible.
05:18 PM bjorkintosh: in all these years of carefully searching, I've not been able to determine who first created G-Code.
05:18 PM bjorkintosh: someone said it came from Gerber Scientific (hence the G) but I've no firm proof of that.
05:19 PM bjorkintosh: they boys at MIT favored APT.
05:20 PM bjorkintosh: so I know it didn't come from them.
05:26 PM andypugh_: Do you have LinuxCNC installed? If so, look at the sample config sim/axis/canterp That uses a trivial interpreter (as a demonstration) that parses canonical motion commands (ie, the low-level motions commansds of Linuxcnc)
05:27 PM andypugh_: This is the sample input file: https://github.com/LinuxCNC/linuxcnc/blob/master/configs/sim/axis/canterp_example.can
05:27 PM Tom_L: MIT is also taking credit for gcode
05:27 PM bjorkintosh: Tom_L, where?
05:27 PM memleak: hey andypugh_ how you been? :)
05:27 PM andypugh_: busy, mainly,
05:28 PM Tom_L: The first G-code was created in 1958 at the MIT Servomechanisms Laboratory. Subsequent versions have been developed by various machine and controller manufacturers, generally using variations on the G-code standard, each tailored to the developers' own equipment.
05:28 PM andypugh_: But NIST RS274-NGC is the best.
05:29 PM Tom_L: https://www.techtarget.com/whatis/definition/G-code
05:29 PM andypugh_: (because _we_ define that one, now)
05:30 PM bjorkintosh: Tom_L, it's written by one "TechTarget Contributor"
05:30 PM bjorkintosh: in the 1950s, they were using APT.
05:30 PM Tom_L: probably done in somebody's garage late at night
05:31 PM bjorkintosh: Douglas T Ross was a researcher at MIT in the servo lab.
05:31 PM bjorkintosh: https://dl.acm.org/doi/10.1145/960118.808374
05:38 PM bjorkintosh: I got a copy of this book, hoping it would have a definitive history https://books.google.com/books/about/Numerical_Control.html?id=JNlSAAAAMAAJ
05:38 PM bjorkintosh: but it didn't even mention G-Code anywhere in it. It's written by the folks from MIT.
05:40 PM Tom_L: guess they wanna keep you guessing
05:42 PM bjorkintosh: yeah. I suspect it was an industrial effort, not an academic one.
05:42 PM Tom_L: the paths had to cross some
05:43 PM bjorkintosh: yes. it started in industry, moved to academia, and then seeped out from there back to industry.
05:44 PM bjorkintosh: one of the early books on CNC was written by Pierre Bezier (of the curves) himself.
05:44 PM Tom_L: i suppose alot of those 'beginnings' books depend on who wrote it
05:44 PM JT-Shop: yup
05:44 PM JT-Shop: history is written by the winners
05:45 PM CloudEvil: Only if they can write.
05:45 PM Tom_L: probably several were working toward the same end and whoever got there first..
05:45 PM bjorkintosh: naturally. but why didn't MIT take the win?
05:46 PM Tom_L: find archivist... he probably has a book on it :)
05:46 PM bjorkintosh: is @archivist here?
05:46 PM Tom_L: although i think most of his were manuals
05:46 PM Tom_L: no he left irc for greener pastures
05:46 PM JT-Shop: not in a long time
05:46 PM bjorkintosh: oh damn.
05:47 PM JT-Shop: is his website still up?
05:47 PM Tom_L: no idea
05:47 PM Tom_L: bjorkintosh, andy may know how to reach him
05:48 PM bjorkintosh: I like to think I was thorough, but even the NIST documents just handwave the origins of G-Code. it's an old language, but it's arguably one of the most important old programming languages still in daily use.
05:48 PM Tom_L: would be a long shot but he may have something
05:49 PM bjorkintosh: it never gets mentioned when Cobol and fortran and Lisp are mentioned.
05:49 PM Tom_L: they were the cool kids
05:49 PM bjorkintosh: well, I guess SQL and Cobol were responsible for the ERP and MRP systems that co-ordinated the front office
05:51 PM Tom_L: https://www.taledo.com/blog/nasa-is-hiring
05:51 PM Tom_L: ever read that?
05:52 PM bjorkintosh: No!
05:52 PM bjorkintosh: but the answer is GPT
05:52 PM bjorkintosh: also, will they train?
05:52 PM bjorkintosh: of course not.
05:52 PM bjorkintosh: and now I see it's 8 years old.
05:53 PM Tom_L: i knew it'd been out a while
05:53 PM Tom_L: they may still be looking :)
05:56 PM * JT-Shop looks forward to a quiet cool night
05:56 PM Tom_L: :)
05:57 PM CaptHindsight: high here in the 60's F tomorrow, fall weather again
05:58 PM CaptHindsight: 16-20C
05:59 PM CaptHindsight: “The standard price of the Sweet Potato is $35.00, but as of the publication date (excluding shipping), it is being sold for a discounted price of $30.00 on the LoveRPi website. https://linuxgizmos.com/libre-computer-showcases-low-cost-sbc-with-poe-support/
05:59 PM JT-Shop: got someone to buy my roof jacks :)
05:59 PM Tom_L: roof jacks?
05:59 PM JT-Shop: I just have to figure out a way to fit them in the C8
05:59 PM CaptHindsight: oh no
05:59 PM JT-Shop: you nail them down and put a board across so you have a place to stand
05:59 PM CaptHindsight: JT-Shop, don't you have a truck/SUV?
06:00 PM Tom_L: yeah but why if he has a C8?
06:00 PM JT-Shop: truck, car and C8
06:00 PM JT-Shop: but tomorrow is a C8 day
06:00 PM JT-Shop: https://www.homedepot.com/p/Guardian-Fall-Protection-6-in-x-90-Fixed-Roof-Bracket-2502/202092095
06:00 PM CaptHindsight: never haul in the nice car
06:00 PM JT-Shop: oh and a BlueWing...
06:01 PM JT-Shop: they are pretty small so I'll put a moving blanket in the truck and fill it will the roof jacks
06:02 PM Tom_L: got rid of the spyder?
06:02 PM CaptHindsight: https://youtu.be/hFHbeVCKrDo
06:02 PM JT-Shop: yup
06:02 PM CaptHindsight: Motorcycle Timber & Pipe Carrier
06:02 PM JT-Shop: I've carried a 4x8 sheet of plywood on a Honda 50
06:03 PM CaptHindsight: https://youtu.be/JaubfRLyHJg
06:03 PM CaptHindsight: you should see what they haul on scooters in Chine
06:04 PM JT-Shop: I've seen what they haul on their heads in Africa and scooters galore in Taiwan
06:04 PM CaptHindsight: I was standing on the street one day when a trike pulling a load of old pipes rode by
06:05 PM CaptHindsight: I stepped back and looked for a place to run
06:05 PM memleak: This one still gets me: https://www.youtube.com/shorts/aQqOjbzFvpw

06:10 PM Tom_L: there's the rest
06:10 PM JT-Shop: you wouldn't do that with my hoe
06:11 PM XXCoder: very safe
06:12 PM Tom_L: they thought so
06:13 PM Tom_L: memleak, i wouldn't wanna get into a bar fight with him
06:13 PM CaptHindsight: http://tom-itx.no-ip.biz:81/~webpage/women_vs_men/8.jpg ironworkers regularly do things like this while not at work
06:20 PM * JT-Shop calls it a night
06:44 PM Unterhaus__ is now known as Unterhausen
06:44 PM Unterhausen: some horrible person drove into a power pole and ruined everyone's air conditioning on that end of town
06:45 PM Unterhausen: weather people say that it felt like 98F today
06:47 PM solarwind: memleak LOL
06:48 PM XXCoder: delibrately or?
06:50 PM solarwind: Yeah it's been insanely hot here. Inside has gotten hotter than it ever has this year. 32°C
06:51 PM solarwind: I just get tired when it's above 26°C
06:52 PM solarwind: Somehow my cat kills wasps in mid air without ever getting stung. I love her to bits, such a cute cat
07:29 PM CaptHindsight: solarwind: murder paws
07:29 PM solarwind: They have one of the fastest reflexes of all mammals I think
07:29 PM CaptHindsight: sol,
07:30 PM solarwind: https://www.youtube.com/shorts/LeTwcBaSsV0 here's one slapping a snake that wants to attack, twice
07:30 PM XXCoder: its reason cats is everywhere in all sizes
08:18 PM Unterhausen: that cat smacking the snake was awesome
09:34 PM memleak: Well this happened in Nebraska: https://www.youtube.com/watch?v=yIR3NU3P_bU
09:40 PM bjorkintosh: I still don't see why they stopped him.
11:02 PM roycroft: seat belt violation by the passenger
