12:25 AM veegee: I'm contemplating getting a double rear wheel pickup for towing heavy things
12:31 AM veegee: what's the downside of a diesel engine other than it being insanely polluting?
12:31 AM veegee: the crazy boosted gasoline engines (EcoBoost) that ford is pushing doesn't sit well with me for some reason
12:31 AM veegee: 15 PSI boost on an aluminum engine block
12:31 AM veegee: I mean, I wouldn't mind one of them ecoboost engines in my jeep wrangler. But I don't know about a pickup truck for towing applications
12:33 AM gloops: hmm, cant think of any downsides for diesel engines
12:34 AM gloops: different wiring loom to petrol models though
12:43 AM Deejay: moin
01:10 AM CaptHindsight: veegee: do a Cummins swap and quit compainin
01:10 AM CaptHindsight: and throw the Jeep away
01:11 AM veegee: I've had that car for 13 years
01:11 AM veegee: it works like new
01:11 AM CaptHindsight: i used to go through front differentials
01:11 AM veegee: But yeah diesel it is for any truck that'll be used for towing/PTO
01:11 AM veegee: I had 0 issues in 13 years
01:12 AM veegee: but I do all my own maintenance. I don't let idiot mechanics touch my car
01:12 AM CaptHindsight: I just drive land cruisers now
01:12 AM veegee: One time I got my tires replaced, and the dumbshit didn't torque wrench the lung nuts
01:12 AM veegee: He refused to
01:13 AM veegee: I yelled at him to get his manager and he made him do it. But that's the kind of shit I will not accept
01:14 AM CaptHindsight: been doing it all myself for decades
01:14 AM CaptHindsight: everyone has the same story, but we all fix our own things
01:20 AM snakedGT is now known as snaked
01:39 AM gloops: petrol diesel conversion, new engine..gearbox? different ECU which has to be reconciled with ignition/immobilser etc
01:39 AM gloops: exhaust
01:40 AM gloops: against sell the petrol and buy a diesel vehicle
02:23 AM CaptHindsight: <CaptHindsight> pneumatic good enough?
02:23 AM CaptHindsight: <ziper> no, needs to be a stiff response ziper> someone else mentioned pneumatic cylinders, what is what I will try
04:47 AM JT-Cave: morning
04:49 AM XXCoder: hey
05:14 AM JT-Cave: I need to get my focus back and get some work done
05:17 AM XXCoder: one of those bleh days eh
05:17 AM JT-Cave: well yesterday was a rough day, had to put one of my 3 year old hens
05:18 AM JT-Cave: put down
05:19 AM XXCoder: flyimpact or something isnt it
05:19 AM XXCoder: that sucks :(
05:20 AM JT-Cave: yea flystruck
05:20 AM JT-Cave: I tried like hell to save her but it was just too bad
05:23 AM XXCoder: any others has the issue?
05:24 AM JT-Cave: no, it's from an open sore that flies lay eggs in and the maggots eat the dead tissue
05:25 AM XXCoder: so wounds is required for that to get dangerous
05:25 AM JT-Cave: yea
05:25 AM XXCoder: some doctors use maggots as precisely that, removal of dead tissue but with control
05:25 AM XXCoder: but when its not in control its not great
06:12 AM Tom_L: morning
06:12 AM Tom_L: 48F light rain
06:14 AM JT-Cave: nice
06:15 AM JT-Cave: we are still in the heat wave
06:15 AM XXCoder: will be 88f here. sunny
06:15 AM XXCoder: looks like last high day, next day i 81f then 70s to low 70s
06:32 AM jymmmm: Morning, looks liek the fire has grown, but moving away from me at least for the moment.
06:33 AM XXCoder: thats good
06:33 AM XXCoder: my sis might be in yellow air quality zone soon
06:33 AM XXCoder: meaning she need to evac
06:36 AM robotustra: who is firing the forest?
06:36 AM robotustra: people or natire?
06:37 AM XXCoder: no idea
06:37 AM XXCoder: they are too busy dealing with it for now
06:37 AM robotustra: who "they"
06:38 AM XXCoder: firemen and such
06:39 AM robotustra: was the situation worse previous years?
06:41 AM XXCoder: 2 years ago was REALLY nasty
06:41 AM XXCoder: i wore mask everyday outside for over a month
06:41 AM XXCoder: but same time its really bad this year too
06:41 AM XXCoder: just not where i live at
06:44 AM beachbumpete1: Morning
06:46 AM XXCoder: hey
06:50 AM jymmmm: robotustra: Started with lighting strkes in august, then combined and grew
06:50 AM XXCoder: whats happening in amazon though? looks like hundreds of fires there
06:51 AM jymmmm: huh?
06:51 AM jymmmm: XXCoder: amazon.com? amazon jungle?
06:52 AM XXCoder: i'd be shocked if there was many fires at amazon.com lol
06:52 AM XXCoder: no the jungle of course
06:54 AM robotustra: jymmmm, it means it's nature, not humans
06:55 AM XXCoder: you do realize climate change is caused by humans?
06:55 AM XXCoder: hotter and drier means fires is more common
06:55 AM XXCoder: "caused by human" "caused by nature" is a moot point
06:58 AM robotustra: XXCoder, it's urban legend. first look at the temperature plot for 100k years
06:59 AM XXCoder: whatever ill not debate
06:59 AM XXCoder: you are not owed a debate
06:59 AM jymmmm: XXCoder: IDK, one of the wildfires could have started a fire at a amazon.com distribution center, and that could have been what you wee referring to.
07:00 AM jymmmm: robotustra: Not necessarily... there was a "baby to be gender reveal party" that used a smoke bomb and caused an uncontrollable fire, which last I checked was up to 100K acres.
07:01 AM XXCoder: jym thats why we stopped having backyard campfires. its damn dry here now
07:01 AM jymmmm: robotustra: Sorry, 10K acres... https://www.cnn.com/2020/09/08/us/el-dorado-fire-gender-reveal-update-trnd/index.html
07:02 AM robotustra: jymmmm, that's why I asked
07:02 AM robotustra: human or nature
07:02 AM jymmmm: robotustra: both
07:02 AM robotustra: yep. looks like
07:04 AM jymmmm: XXCoder: We had a blackout from Monday to Wednesday, so on generator and cooked on BBQ. So much smoke and ash that it's pretty cold now, suppose to be 89F today but only 62F and yesterday the high was 72F, but should have been 87F
07:05 AM XXCoder: ow
07:05 AM XXCoder: im worried about my sister too
07:05 AM XXCoder: shes in region that might go yellow in air quality
07:05 AM jymmmm: The same thing happened in Campfire (2018), but MUCH colder then
07:13 AM jymmmm: XXCoder: Yesterday morning around 7am, you looked out and thought it was 5am, SO SO DARK and really deep orange sky. Thought a fire was coming over the ridge for us. Many people evacuated because they lost everyting in Campfire and didn't want to take a chance.
07:13 AM XXCoder: :( you evacuated yet?
07:13 AM jymmmm: XXCoder: No, the fire is moving away from me, but keep watching for updates as I can. Contacting CalFire, Sherriff, and CHP for updates, evacuations orders/warnings, and road closures.
07:21 AM XXCoder: cheap crap one might still do work i'd get bit better than cheapest
07:21 AM jymmmm: Well, I could just run the HVAC on "fan only",
07:21 AM jymmmm: that would do the whole house.
07:21 AM XXCoder: yeah or keep room cleaner fast
07:21 AM jymmmm: or what now?
07:21 AM Tom_L: jymmmm, it will draw the soot in the return air ducts before it gets to the filter
07:21 AM XXCoder: the hvac thing? or that box fan thing
07:21 AM Tom_L: hvac
07:21 AM XXCoder: ok
07:21 AM jymmmm: Ah, well the return has the filer right before it, so would catch before entering the system.
07:21 AM Tom_L: k
07:21 AM jymmmm: and I think I have a couple of filters on hand already.
07:21 AM Tom_L: i keep a box on hand
07:21 AM XXCoder: i have true hdpe fan cleaning my room
07:21 AM jymmmm: I do not
07:22 AM XXCoder: if "sometime" suddenly turns to "now" youre in good place
07:23 AM jymmmm: Eh, could be better, but dealing with a LOT of things besides fire
07:23 AM XXCoder: isnt birds sensive to smoke
07:27 AM jymmmm: Yes, to most respritory issues. That's why I keep the house closed. I know it's effective because I can step outside and smell the smoke, but not inside.
07:27 AM XXCoder: thats good
07:28 AM jymmmm: But I'll plug in the ion filter in their room so that should be a bonus thing.
07:29 AM jymmmm: Bah, I think I'm almost out of nitrogen too :(
07:30 AM jymmmm: I already have two 2L soda bottles filled with bird seed in the car that have been nitrogen filled, but having a 3rd wouldn't hurt.
07:33 AM XXCoder: nitrogen for long life for seeds?
07:33 AM jymmmm: Bird seed (well, any grain really) have what called "seed bugs" in it, and they turn to small worms, etc. Freezing doens't kill them. putting in the microwave doens't kill them. But putting the seed in nitrogen has worked VERY effectively for 2+ years shelf life test.
07:33 AM XXCoder: wow interesting
07:35 AM jymmmm: XXCoder: Yeah, it's a big issue in the bird community, but not everyone has a 80CF nitrogen tank to try it with. But we had the issue for years and it couldn't hurt to try it, so I did and it's worked great. Not sure if the seed is rancid or not, but not seed bugs.
07:36 AM jymmmm: But is has to be in SODA bottles, not water bottles.
07:37 AM jymmmm: SODA bottles are designed to withstand 120PSI, water bottles are not. The threads are different too.
07:40 AM miss0r2: happy days: standing here trying to rescue data from an IDE harddrive (quamtum fireball) that used to run NT4 workstation...
07:51 AM miss0r2: aaaand my computer does not recognize anything.. fak
08:41 AM solobolo2 is now known as htasta
08:41 AM htasta: miss0r2: try different computers I had to try a few different ones until my old IDE HDDs were detected.
08:44 AM * JavaBean has an old usb2 ide hdd enclosure that has worked on every drive he has gotten
08:48 AM miss0r2: that is the case with my adapter... but apparently this disk id illusive
10:54 AM skunkworks: http://electronicsam.com/images/greenmachine/Pictures.png
10:54 AM skunkworks: over night
10:55 AM skunkworks: rt_preempt
11:19 AM Eric__: I swear our tomatoes are never going to get ripe
11:27 AM FinboySlick: skunkworks: I don't know if it's good, but it's certainly symmetrical.
11:30 AM Rab: skunkworks, have you tested different isolcpus parameters?
11:36 AM Eric__: +/- 6 microseconds is really good, about as good as you are going to find
11:37 AM Eric__: I'm pretty sure he tested 1/2/3 isolcpus, not sure where the graphs are
11:42 AM Rab: OK, I see from the wiki that isolcpus=3 is recommended for a quad-core cpu on preempt_rt. I'm on rtai, looks like notes for that are pretty outdated. I guess I should test!
12:17 PM skunkworks: I should try idle=poll
12:18 PM skunkworks: but I doubt it will get much better
12:18 PM skunkworks: that is rtai numbers
12:18 PM Tom_L: try rpi yet?
12:18 PM skunkworks: in my experience
12:18 PM skunkworks: Tom_L: I have not tried the latest image.. But I didn't think much changed?
12:19 PM Tom_L: i don't either, maybe just the way it updates now?
12:19 PM skunkworks: did the fix the new kernel update issue? iirc that being the problem
12:19 PM Tom_L: maybe a couple feature exclusions?
12:19 PM Tom_L: i dunno
12:20 PM Tom_L: i'm not gonna update until i get my spindle
12:24 PM Rab: skunkworks, really? The pic shows 4.19.0-10-rt-amd64, I thought that was preempt_rt.
12:24 PM Tom_L: sounds like it
12:24 PM skunkworks: Rab: I mean - those numbers are usually only achieved by rtai.
12:25 PM skunkworks: I still have to try my radiused polygons
12:25 PM skunkworks: got side tracked with an air compressor
01:28 PM CaptHindsight: Rab: you don't need to use isolcpus for RTAI for the past 5-6 years
01:30 PM CaptHindsight: There is a new scheduler in RTAI for 3.10 and 3.14. It no longer requires any isolcpus settings.
01:30 PM CaptHindsight: 3.14 RTAI is in the testing stage at the time of this writing (September 2014).
01:31 PM CaptHindsight: uname -r will tell you which kernel you are running
01:34 PM CaptHindsight: satellite images of Oregon before and after fires https://www.cnn.com/2020/09/10/us/satellite-images-oregon-wildfire-trnd/index.html
01:35 PM Rab: CaptHindsight, I see. I'm on andy_pugh's 4.14.174-rtai.
01:37 PM CaptHindsight: Rab: unless something broke you can ignore isolcpus on that
01:46 PM zipper is now known as Guest45268
01:47 PM Eric__: the last rt-prempt wasn't great on my dell i5, unfortunately
01:48 PM Rab: CaptHindsight, I tried isolcpus=[0-3] and didn't see a big difference anyway. But I added 'idle=poll nohlt' and max jitter dropped like a rock to ~1500ns. All cores are running 10C warmer though. ;)
01:48 PM Rab: I suspect nohlt isn't doing anything.
01:51 PM CaptHindsight: yes, it runs the cores at max
01:52 PM CaptHindsight: if the BIOS wasn't a big turd one should be able to set the cores to not change speeds
01:53 PM Rab: It's a Compaq SFF with a turd for a BIOS.
01:54 PM CaptHindsight: keeping the cores running non-real time threads must help on that CPU BIOS combo
01:56 PM CaptHindsight: all the BIOS dev did for that system was likely check off a bunch of boxes in an IDE and then run windows to see if it behaves
01:58 PM Rab: http://reboots.g-cipher.net/histogram-10Sep2020-208.png
01:58 PM Rab: (Not running overnight, however)
02:02 PM CaptHindsight: beat it up running FF with a youtube playing
02:03 PM CaptHindsight: back in a few
02:43 PM * JT-Shop found a 123 block that has seen many years of use and it's marked F. H. FRISBIE
02:45 PM Tom_L: who's he?
03:06 PM JT-Shop: some machinist long gone I suppose... never seen a 123 block with 3 holes in the 2" side
03:06 PM CaptHindsight: not Frisbee
03:06 PM JT-Shop: only 1 e
03:14 PM Deejay: gn8
03:44 PM Tom_L: JT-Shop, mine are holy blocks: http://tom-itx.no-ip.biz:81/~webpage/cnc/rotary/123Block.jpg
03:52 PM JT-Shop: yea all of mine are like that except this one, google fails to find one like it...
03:52 PM Tom_L: huh
03:59 PM XXCoder: tom yeah mines like that, pretty standard
04:00 PM JT-Shop: I'll take a photo of it after I knock off work
04:00 PM XXCoder: cool
04:04 PM Eric__: we had some 2 4 6 blocks, they were nice
04:04 PM Eric__: can't call them 1 2 3 blocks or some pedant would correct
04:04 PM XXCoder: i wanted one but its a huge jump in price lol
04:05 PM Eric__: they aren't particularly common
04:07 PM Eric__: trying to remember who made those cylindrical squares that measure tilt
04:08 PM XXCoder: who calls 246 123 block?
04:09 PM Eric__: I do
04:10 PM Eric__: it's 123 under some trivial transformation of units
04:10 PM XXCoder: but if you say "123 please" someone would hand you regular size?
04:11 PM Eric__: never had that happen in context
04:11 PM Eric__: plus, nobody ever hands me anything, they just argue over nomenclature
04:12 PM Eric__: are there metric 1 2 3 blocks? Doesn't seem like they would be particularly useful
04:14 PM roycroft: there are 25-50-75 blocks
04:14 PM XXCoder: yeah
04:14 PM Eric__: I see that.
04:14 PM XXCoder: fun numbers on metric
04:14 PM Eric__: seems like a pita
04:15 PM XXCoder: 123 cm block is useless
04:15 PM Tom_L: but nobody remembers them cause metric
04:15 PM Eric__: having a set of those metric ones in the shop might be problematic
04:15 PM XXCoder: 123 dm block is too large
04:15 PM Tom_L: you say 123 block and everybody knows what you're talking about :)
04:15 PM JT-Shop: https://gnipsel.com/images/machine-shop/tools/123block.jpg
04:16 PM roycroft: ask anyone not in the usa, liberia, or myanmar how useful they are compared to 1"x2"x3" blocks :)
04:16 PM XXCoder: wow so unusual
04:16 PM Eric__: what is that ramp, do you suppose?
04:16 PM XXCoder: milled off by mistake i bet
04:16 PM JT-Shop: user modification
04:17 PM Eric__: okay, it looked stock at first glance
04:17 PM roycroft: yes, that ramp is something robotustra is incapable of making :)
04:19 PM Eric__: I bet that gear he wanted would cost the same as his machine if he found someone to give him an honest price
04:19 PM JT-Shop: there are several marks from being almost in the right spot...
04:19 PM Eric__: lol
04:19 PM XXCoder: lol
04:21 PM Tom_L: Eric__, sdp-si would make it for him
04:21 PM Tom_L: dunno what they charge for custom
04:22 PM Eric__: they might be cheaper, if he could figure out what the specs are
04:23 PM Eric__: I knew someone that replaced all the gears on his Sheldon 56 because they made the lathe wrong
04:23 PM Eric__: according to him anyway
04:24 PM roycroft: oh, what would be so much fun would be to point that person to the sheldon forums so he could discuss how "they made thelathe wrong"
04:24 PM Eric__: I think the company might be surprised at that conclusion
04:25 PM Eric__: there is an ex employee that is still around, we hope
04:25 PM roycroft: i'm not sure i've ever met a group of folks who so fiercely defend their preferred products as sheldon owners
04:26 PM Eric__: my lathe was really nice before some jerk got ahold of it
04:26 PM Eric__: and I'm not talking about myself
04:26 PM roycroft: see, you can't say that on a sheldon forum
04:27 PM Eric__: incompetently used it go grind brake discs
04:27 PM XXCoder: isnt that make truly nasty powder
04:27 PM roycroft: you would have to say "my lathe is really nice, but someone modified it incorrectly, and i need to make it as great and sheldon-like as possible"
04:27 PM XXCoder: including currently banned except for special uses abestos
04:27 PM Eric__: after I bought it someone told me to never buy a lathe that comes with a toolpost grinder. Too late
04:28 PM CaptHindsight: had someone offer me NET75 payment terms for R&D, still laughing
04:28 PM XXCoder: hope you cleaned lathe carefullu of any powder to avoid any getting in your lungs
04:28 PM Eric__: huh, maybe I should
04:29 PM Eric__: the only original dirt left is inside the motor cabinet
04:29 PM XXCoder: discs itself dont have much but likely it had some dust on it as iots cleaned up on lathe
04:29 PM XXCoder: from pads
04:30 PM Eric__: CaptHindsight usually net30?
04:31 PM XXCoder: thats good you cleaned it up :)
04:32 PM Eric__: I think the guy that sold it to me had cleaned it
04:33 PM XXCoder: ok the remaining stuff be careful
04:33 PM XXCoder: stay safe
04:33 PM XXCoder: abestos dont go away unlike isulation stuff we use now
04:33 PM Eric__: roycroft, Gene Heskett is on the sheldon lists, but I don't know if he ever mentions that he cnc'd his sheldon
04:34 PM Eric__: I was thinking about cnc'ing mine, but for now I'm fixing whatever is wrong with the apron
04:37 PM Tom_L: Eric__, i think he gave most of the specs
04:38 PM Tom_L: 37T 1.25? pitch 10deg helix 15mm bore, 5mm key and iirc 10mm width
04:38 PM _unreal_: t4nk_freenode, make anything new?
04:38 PM Tom_L: off the top of my head anyway
04:38 PM t4nk_freenode: hey man
04:38 PM _unreal_: ve7it, If I get a chance I may be working on the controller tonight....
04:39 PM Tom_L: _unreal_, how _is_ your mill going?
04:39 PM _unreal_: MINE FINE
04:39 PM _unreal_: My daughters is what I'm working on mainly right now
04:39 PM Tom_L: the one with the ve7it controllers?
04:39 PM t4nk_freenode: _unreal_, yeah, I'm in the process of making a drill press... for my dremel knockoff, but I guess it will also hold my normal drill
04:39 PM _unreal_: on the ve7it controller one is on hold till I can get the controlle working
04:40 PM _unreal_: I solved the short... but now I need to get a time frame to chat with ve7it and figure out what I'm over looking. the controllers are not tracking the encoders
04:40 PM roycroft: sorry, i did not mean to bring us back to the topic of the unneeded gear made of unobtanium
04:41 PM _unreal_: roycroft, you WOULD
04:41 PM _unreal_: heh
04:41 PM Tom_L: secretly i think you enjoy it
04:41 PM _unreal_: shhhhhhh
04:42 PM Eric__: now I want to know how much they would charge to make it
04:42 PM t4nk_freenode: I printed linear bearings.. they work great.. it's mostly done, I cut a threaded rod.. short of course :| so I gotta cut some new ones.. attach the back and double bottom.. it's really, really sturdy! and the bearings.. well, they run a lot more heavy now.. but smooth I won't need a spring
04:42 PM Eric__: my experience with stuff like that is they ain't giving it away
04:42 PM Tom_L: Eric__, call em up and have one made
04:43 PM Eric__: it would be funny to tell him I have one
04:43 PM Eric__: but I can do that without actually having one made
04:43 PM ve7it: _unreal_, nice... encoder issue should not be too bad to trouble shoot... check the encoder is getting 5V, measure the A and B phases while VERY slowly moving encoder... they should switch from 0 to 5V and back... if always near 0, you probably need to add a couple of pull up resistors (A to 5V through 1K) and the same for B
04:43 PM _unreal_: https://drive.google.com/file/d/1CmrYrmrUiMfIK1lErBgWneq1AzxUFwbn/view?usp=sharing
04:44 PM Tom_L: Eric__, most if not all the specifics are in the log
04:44 PM _unreal_: pull up near the motor or anywhere in the line?
04:44 PM _unreal_: arg... currently I'm on hold trying to get a hold of uiversal studios trying to cancle my annual passes
04:45 PM _unreal_: cancel
04:45 PM Tom_L: anywhere should be ok but i'd put them by the encoder so you know what they're for
04:45 PM _unreal_: till the fake BS virus is over not worth paying for the passes
04:45 PM _unreal_: and I'm loosing to many hours at work
04:46 PM _unreal_: I made that part for my daughters cnc machine. her little machine is going to be using an arduino with grbl
04:47 PM Tom_L: with signals fwd/rev, ena, pwm how would one go about engaging a brake just before a fwd/rev change?
04:47 PM _unreal_: ve7it, if I can get this @#$@#$ being on hold with universal studios over I can jump over ot the contoller
04:47 PM Tom_L: but not fwd or rev to stop
04:48 PM _unreal_: as I recall I believe I was getting 4.85v at the encoder..
04:48 PM Tom_L: just if it went from fwd to rev or vise versa
04:51 PM ve7it: _unreal_, I am pretty sure those motors have 5V encoders... but I have seen 12 and 24V encoders... dont get the supplies mixed up!
04:51 PM _unreal_: e
04:51 PM _unreal_: heh
04:51 PM _unreal_: ya
04:51 PM _unreal_: I'm rather certain they are 5v
04:51 PM CaptHindsight: Eric__: my R&D is pay as you go up front
04:52 PM _unreal_: ok so ve7it the issue was one of the mounting screws holding the op amp chips had a mounting screw that was touching it
04:52 PM _unreal_: so that made the SHELL hot
04:52 PM roycroft: please do not denigrate the close to 200,000 people who have died in this country alone from covid-19 by calling it a "fake virus"
04:52 PM JT-Shop: Tom_L, what are you trying to do?
04:52 PM roycroft: believe what you will, but keep such hurtful comments off this channel
04:53 PM JT-Shop: lol ignore works
04:53 PM CaptHindsight: roycroft: I just ignore the fools
04:53 PM _unreal_: my only key was the serial adapter ground touched the hell for a second and tossed some minor sparks I said WTF...
04:53 PM _unreal_: thats when I found out the shell was hot
04:53 PM roycroft: i'm not going any further with it
04:53 PM _unreal_: I dont think I caused any damage
04:53 PM roycroft: but i feel compelled to call it out once in a while
04:54 PM CaptHindsight: I must say that tend to be real weasels, how many hours wasted to get this idiots BLDC motors working?
04:54 PM _unreal_: all the controllers are now working much better having removed the short.
04:54 PM _unreal_: before the serial data was doing weird shit
04:54 PM _unreal_: ve7it, the settings on the controllers are more or less virgin
04:56 PM ve7it: _unreal_, defaults should work... I cant remember, but you may have to change something to get the servo to enable.. it knows when its a virgin!
04:56 PM _unreal_: so our saying I may need to pop that cherry
04:56 PM _unreal_: your
04:57 PM _unreal_: lol
04:57 PM JT-Shop: I found one of my Dad's business cards... has his name and phone number and an image of a Cessna 310
04:57 PM _unreal_: the Y just spins endlessly
04:58 PM _unreal_: the X the motor pulses on power up and does not spin. before it did spin endlessly
04:58 PM _unreal_: I did try switching the A/B and +/-
04:58 PM _unreal_: settings I did not touch
04:58 PM _unreal_: OMG..... ( we are experiencing high call volume. your wait time may be geater then 3min...) its been saying that same crap for the past 30min
04:58 PM _unreal_: @!$@#$
04:59 PM ve7it: use the serial status command to view the encoder readings.... nothing will work until the encoder reads correctly
04:59 PM _unreal_: command E I believe
04:59 PM _unreal_: I did and there was no change when I manually job the motors
04:59 PM _unreal_: witht he motor +v unplugged
04:59 PM _unreal_: job=jogged
05:00 PM _unreal_: I've been on hold with a 3min wait time since 5:20 OMG
05:03 PM Tom_L: JT-Shop2, this control recomends enabling the brake before switching directions so i was gonna pulse it before switching if possible
05:03 PM Tom_L: i'm not sure it's all that necessary but i've not dealt with a vfd before
05:04 PM Tom_L: but if it's just going from fwd to stop or rev to stop there's no real need to brake
05:06 PM Tom_L: i did something similar when i was testing rigid tapping on this sherline motor
05:07 PM Tom_L: but it may not work the same
05:15 PM Tom_L: The last 310 was pushed out the factory door in Wichita in 1981.
05:18 PM _unreal_: omg what a pain.
05:18 PM _unreal_: done
05:18 PM _unreal_: universal pass cancled
05:20 PM JT-Shop: Tom_L: you can just do that in g code if your brake is on when the spindle is off
05:27 PM Tom_L: i'm not sure the brake needs to be on all the time
05:28 PM JT-Shop: on my lathe the brake is on if the spindle is off, you might have different needs
05:28 PM Tom_L: the only real time i would use it would be during rigid tapping
05:28 PM Tom_L: and the rpm would be slow enough switching from fwd to rev may not be that big a deal
05:28 PM JT-Shop: you could use a DIO to pulse the brake
05:29 PM Tom_L: yeah, i've got a pulse set up for something currently
05:31 PM JT-Shop: looks like the 2.8 iso is burning here, debian 10 brasero is broken lol
05:31 PM Tom_L: it was a way i came up with to get the fwd only sherline driver to do reverse
05:32 PM JT-Shop: be back in a bit need to add a bit of food to the pullets food tray
05:32 PM Tom_L: it will take some experimenting when it arrives i'm sure
05:39 PM zipper is now known as Guest88483
05:45 PM JT-Shop: well crumb for some reason this pc won't boot from the dvd drive
05:46 PM XXCoder: look at bios boot order
05:47 PM JT-Shop: the drive does not show up
05:47 PM CaptHindsight: JT-Shop: how is this drive connected to the OC? which BUS?
05:47 PM CaptHindsight: OC/PC
05:48 PM JT-Shop: sata
05:48 PM CaptHindsight: did it boot before and just not now or it has never booted from the DVD?
05:48 PM JT-Shop: no clue
05:49 PM CaptHindsight: check cables etc
05:49 PM JT-Shop: it sees the dvd I just put in
05:49 PM CaptHindsight: try SATA DVD in a different PC etc
05:49 PM JT-Shop: ok
05:50 PM CaptHindsight: "JT-Shop> it sees the dvd I just put in" a different DVD drive?
05:54 PM * JT-Shop gives up for today
05:55 PM XXCoder: have to look into bios. it can enable or disable boot from various media
05:55 PM XXCoder: honestly i'd use flash drive or something. better that way
05:55 PM JT-Shop: better in what way
05:56 PM XXCoder: easier to setup your own drive
05:56 PM Tom_L: it's an iso image
05:56 PM XXCoder: fewer and fewer pcs has cd/dvd drive
05:57 PM JT-Shop: it's pretty easy to put a dvd in an boot up
05:59 PM XXCoder: yeah. though have to be enabled at bios
06:06 PM CaptHindsight: https://imgur.com/gallery/vSk1SW6 if you look closely you can see how hot the CPU gets in this case, hot enough to boil the coolant
06:09 PM CaptHindsight: 49C boiling point, so pretty efficient at carrying the heat away from the surfaces
06:10 PM CaptHindsight: oh and another at only 34C boiling point
06:11 PM robotustra: it will create bubbling sounds, deny
06:21 PM JT-Cave: XXCoder, what do you mean it has to be enabled in the bios?
06:21 PM XXCoder: not always required depends on what default is
06:21 PM XXCoder: bios is where you can enable or disable boot from cds, usb drives, portable hard drive, hard drive
06:22 PM JT-Cave: IIRC that is the only pc that won't boot from the dvd drive and maybe it's the usb stick with freedos dunno
06:22 PM XXCoder: f5 should show list of allowed and bootable media list (common but not always)
06:22 PM XXCoder: (at bios part of boot)
06:22 PM JT-Cave: yea but the dvd drive does not show up as an option in the bios
06:22 PM JT-Cave: but it works in every other way
06:22 PM XXCoder: thats odd
06:22 PM JT-Cave: yea
06:23 PM JT-Cave: I may try another dvd drive in that pc
06:23 PM XXCoder: can always dd a iso to usb drive
06:23 PM JT-Cave: but I'd really like to get this one to upgrade to 2.8
06:23 PM XXCoder: good idea may be something odd on that drive
06:23 PM JT-Cave: trying to get 2.8.0 from buildbot but I get a depends error https://dpaste.com/FK2HDNWSB
06:24 PM JT-Cave: which is odd as 2.8 is on debian 10
06:24 PM JT-Cave: unless andy did something special with the iso dunno
06:24 PM XXCoder: E: Unable to correct problems, you have held broken packages. this is not a good error
06:24 PM JT-Cave: yea
06:25 PM JT-Cave: it's always some kind of crap
06:27 PM JT-Cave: I wonder if the hens know Pig Pen is gone?
06:27 PM XXCoder: hard to say really. maybe they'd just think some animals got and eat it
06:28 PM Tom_L: JT-Cave, part of those dependency errors were from that graphical lib thing with gmoccapy and gscreen
06:28 PM XXCoder: issue is how much can they really think anyway
06:28 PM Tom_L: the others could be part of that as well
06:29 PM Tom_L: i dunno how they overcame that in buster since it didn't have those either
06:29 PM JT-Cave: I guess the buildbot debs are not as up to date as the iso
06:29 PM Tom_L: possibly not
06:29 PM Tom_L: i think andy was just trying to get the iso out
06:30 PM CaptHindsight: didn't build his own buildbot
06:30 PM JT-Cave: no one has the keys to the buildbot but seb...
06:30 PM CaptHindsight: so he could get it all going
06:30 PM Tom_L: i dunno if andy got them or not
06:30 PM Tom_L: CaptHindsight, i think he worked locally then pushed it
06:30 PM Tom_L: not sure
06:30 PM JT-Cave: I'll prob just build a deb and install that
06:31 PM Tom_L: what os?
06:31 PM CaptHindsight: i thought the buildbot was acting looney since you could try building 3 times without any changes and get different errors each time
06:31 PM JT-Cave: this pc is debian 10
06:31 PM Tom_L: ahh ok
06:31 PM robotustra: got arbor press
06:31 PM JT-Cave: anyway supper time here
06:31 PM robotustra: now I can do broaching!
06:31 PM Tom_L: i'm gonna wait a while on mine but i'd like to install 2.8 eventually
06:31 PM Tom_L: wheezy
07:22 PM veegee: ha nice, "metric horsepower"
07:22 PM veegee: power needed to raise 75kg 1m in 1s
07:23 PM veegee: intentionally almost equal to the freedumb horsepower
07:24 PM _unreal_: linux question for yall.. my daughters computer is a lenovo flex 3 I have fedora 32 on it. just installed a new copy on it.
07:24 PM _unreal_: the onboard keyboard is DOA
07:24 PM XXCoder: like horse, ecept all its lengths etc is in metric system ;)
07:24 PM _unreal_: the touch screen works but I can not get the keyboard to work in linux?
07:24 PM _unreal_: works fine in the bios works fine in windows
07:24 PM veegee: _unreal_ does the keyboard work in the bios
07:24 PM veegee: ah ok
07:24 PM _unreal_: windows is painfully slow on that computer
07:25 PM veegee: press ctrl + alt + 2
07:25 PM _unreal_: linux decent....
07:25 PM _unreal_: 2 or f2
07:25 PM veegee: see if it takes you to the terminal
07:25 PM veegee: right f2 I think
07:25 PM veegee: In the meantime, start flashing a USB flash drive with an ubuntu installer ISO or something like that
07:25 PM veegee: screw fedora, RPM is trash compared to apt
07:26 PM veegee: I don't know maybe it got better since the last time I worked with it, but still
07:27 PM _unreal_: ctrl alt f4
07:27 PM _unreal_: and nothing
07:27 PM _unreal_: an external keyboard wrks just fine
07:27 PM _unreal_: on the other hand some of the FN keys on the lpatop work just fine
07:27 PM veegee: you said you "just installed" fedora on it
07:27 PM _unreal_: but KEYBOARD commands are doa
07:27 PM veegee: so I take it it worked fine in the installer?
07:27 PM _unreal_: I just finished installing a clean install
07:28 PM veegee: that's what I'm saying
07:28 PM _unreal_: no didnt work in the installer
07:28 PM veegee: that should have been red flag #1
07:28 PM veegee: might be missing a kernel driver
07:28 PM veegee: flash an ubuntu installer ISO to a flash drive
07:28 PM _unreal_: dont know
07:28 PM veegee: it'll take you into a live environment
07:29 PM veegee: see if the keyboard works in there
07:29 PM _unreal_: I dont have one setup currently I'm going to have to download/burn
07:29 PM _unreal_: and I'm going to have to put my kid to bed
07:29 PM veegee: orrrr, you could also try plugging in an external keyboard, and run `sudo lspci -vvv`
07:29 PM _unreal_: sigh....
07:29 PM _unreal_: LSPCI...
07:29 PM veegee: your kid has her own laptop but still also has a bedtime?
07:29 PM _unreal_: one sec
07:29 PM veegee: run `sudo lsusb -vvv` as well
07:29 PM _unreal_: one sec
07:29 PM veegee: sudo/root is critical
07:31 PM _unreal_: sudo lspci -vvv gave a huge return as expected
07:31 PM _unreal_: dont know what to grep
07:31 PM _unreal_: my time is running out tonight this may turn into a weekend project
07:32 PM veegee: _unreal_ https://termbin.com/
07:32 PM veegee: pipe it all into there I'll take a look
07:33 PM _unreal_: one sec
07:34 PM _unreal_: http://termbin.com/c3b0
07:34 PM _unreal_: thats lspci
07:35 PM _unreal_: http://termbin.com/h5hn
07:36 PM _unreal_: right now I'm using a logitec usb keyboard external
07:36 PM _unreal_: freaking hell and I'm yawning..
07:40 PM _unreal_: veegee, no issues viewing right?
07:41 PM _unreal_: veegee, the touch screen works GREAT... but as I said I have on onboard keyboard. its dumb founding... the laptop is a "lenovo flex 3"
07:43 PM _unreal_: veegee, you live?
07:43 PM _unreal_: you dead?
07:43 PM _unreal_: :)
07:47 PM _unreal_: veegee, google is giving me nothing about the lenovo flex 3 and the keyboar not working under fedora
07:48 PM veegee: _unreal_ sorry, back
07:48 PM veegee: looking now
07:49 PM _unreal_: you bastard ;)
07:49 PM veegee: You have a logitech unifying receiver, I assume that's for the external keyboard/mouse?
07:50 PM veegee: Linux 5.6, that's pretty new.
07:52 PM _unreal_: yes
07:52 PM _unreal_: I just installed the latest fedora
07:53 PM _unreal_: the keyboard touch pad is ether serial or i2c or usb... as to the onboard that is...
07:53 PM _unreal_: I've seen a few references to serial
07:54 PM _unreal_: the laptop worked fine with fedora 30
07:54 PM _unreal_: if I knew where my life disk was I'd boot it up just to test it..
07:54 PM _unreal_: GOD if I could just get away from people
07:54 PM veegee: _unreal_ run `showkey --scancodes`
07:55 PM veegee: in the terminal, not in X or any graphical environment
07:55 PM veegee: and then press a button on the built in keyboard
07:55 PM veegee: when you press a key, it should show the scancode
07:56 PM _unreal_: couldnt get a file descriptor refering to the console
07:56 PM _unreal_: I an doing a DNF update right now as well
07:56 PM _unreal_: FYI
07:56 PM veegee: so you have no virtual terminals?
07:56 PM _unreal_: couldnt get a file descriptor refering to the console is the error message
07:56 PM _unreal_: um
07:57 PM _unreal_: virtual terminal?
07:57 PM veegee: like ctrl + alt + f2
07:57 PM veegee: it takes you to a virtual console
07:57 PM _unreal_: one sec
07:57 PM veegee: you have to be in a virtual console for the `showkey --scancodes` to work
07:58 PM _unreal_: keyboard code was unicode
07:58 PM veegee: wait what?
07:58 PM veegee: so it does detect it?
07:58 PM veegee: press a bunch of keys on the built in keyboard
07:59 PM _unreal_: the only keyboard that is giving input is the external
07:59 PM veegee: so `showkey --scancodes` doesn't output anything when you press keys on the built in keyboard?
08:00 PM veegee: it doesn't react at all?
08:00 PM _unreal_: nothing
08:00 PM veegee: ok that's some kernel weirdness going on right there
08:00 PM veegee: paste the output of dmesg
08:00 PM _unreal_: nope I take that back
08:01 PM _unreal_: if I hit the FN keys it shows codes
08:01 PM veegee: ok then might be a keyboard mapping issue
08:01 PM veegee: paste the output of dmesg too, there might be something in there
08:02 PM veegee: if the function keys work, the kernel is able to receive data from the keyboard
08:02 PM _unreal_: its being slow right now because of the updates
08:03 PM veegee: paste the output of `ls /dev/input/by-id` as root
08:04 PM _unreal_: I'm still waiting for it to stop choaking
08:04 PM _unreal_: choking
08:04 PM veegee: after that, paste output of `udevadm`
08:05 PM veegee: that'll print out information about all devices
08:06 PM veegee: also see if anything in `/sys/class/input/`
08:07 PM _unreal_: http://termbin.com/i34k dmesg
08:09 PM _unreal_: it wont let me paste the scankey codes
08:09 PM veegee: that's fine
08:09 PM _unreal_: but keycode 225, 224 247 192/193
08:10 PM veegee: as far as dmesg goes, it detected your logitech keyboard
08:10 PM veegee: check /dev/input/by-id and /sys/class/input/
08:10 PM _unreal_: ya thats the external
08:10 PM _unreal_: those codes I just posed are from the onboard
08:11 PM veegee: yeah
08:11 PM veegee: fbcon is loaded, so you have a framebuffer console, that's good
08:11 PM veegee: udevadm should show everything it knows about all devices
08:12 PM veegee: touchpad should work if you install synaptics driver
08:12 PM veegee: it detected the touchpad
08:13 PM _unreal_: termbin.com/jak6
08:13 PM _unreal_: udevadm says requires parameters
08:14 PM _unreal_: the keyboard the external logitec is a touchpad/keyboard
08:14 PM _unreal_: wireless
08:14 PM _unreal_: k400r logitec
08:14 PM veegee: been a while since I used udevadm. Try `udevadm info`
08:14 PM veegee: or `udevadm info -q all`
08:15 PM _unreal_: a device name or path is required
08:18 PM veegee: do ls /dev/input/bi-id
08:18 PM veegee: and /sys/class/input
08:18 PM veegee: what do those directories contain?
08:20 PM _unreal_: termbin.com/5trk
08:21 PM _unreal_: termbin.com/f25x
08:21 PM veegee: 'the second one is from /sys/class/input right?
08:22 PM _unreal_: yep
08:23 PM veegee: for i in `ls /sys/class/input/input*`; do udevadm info -a $i; done
08:23 PM veegee: pipe that to the pastebin
08:24 PM veegee: wait one sec
08:24 PM veegee: error in my script
08:24 PM _unreal_: for i? I'm not sure what you mean by that
08:24 PM _unreal_: heh
08:24 PM veegee: for i in /sys/class/input/input*; do udevadm info -a $i; done
08:25 PM veegee: copy paste the entire line ^
08:25 PM veegee: and add the bit at the end to pipe it to the pastebin
08:25 PM _unreal_: different compute I have to type it LOL
08:25 PM veegee: this will query every input device the kernel is aware of
08:26 PM veegee: if it doesn't show up in there, I'm out of ideas for now
08:26 PM _unreal_: termbin.com/6kwn2
08:26 PM veegee: it's very very likely a kernel thing
08:27 PM _unreal_: I'm thinking its a kernel issue VERY much so
08:28 PM veegee: it's detecting everything _except_ for the keyboard
08:28 PM veegee: it's even detecting the ideapad extra buttons, whatever the hell those are
08:29 PM veegee: it sees the synaptics touchpad too
08:29 PM veegee: I think you just have to use a different kernel
08:29 PM veegee: I don't know enough about how the keyboard in that laptop is interfaced to the system
08:30 PM _unreal_: ya its freaking weird
08:30 PM _unreal_: I think its just a kernel issue with the latest versions of fedora
08:32 PM veegee: I'm pretty sure it'll be fine if you switch it to ubuntu or something
08:33 PM veegee: they compile their kernels differently as opposed to red hat derivatives
08:34 PM veegee: also RPM is a bad way to raise your daughter
08:34 PM veegee: raise her right, use debian
08:34 PM _unreal_: shut yooo mouth ;)
08:34 PM _unreal_: RPM's
08:34 PM _unreal_: hehe
08:34 PM _unreal_: yaI hate to but I may just have to try the latest ubunto on it
08:34 PM _unreal_: freaking weird
08:35 PM _unreal_: well I'm installing updates right now
08:35 PM _unreal_: I'm going to do a kernal update and a few other updates
08:35 PM _unreal_: before she was having on and off keyboard issues
08:35 PM _unreal_: which was weird
08:35 PM _unreal_: I just wiped it out and did a fresh install and the issue with 1000x worse
08:36 PM _unreal_: t4nk_freenode, so what have you printed so far or built so far?
08:36 PM _unreal_: with the 3d printer
09:13 PM t4nk_freenode: ehm
09:13 PM t4nk_freenode: ;)
09:13 PM t4nk_freenode: well.... like I said
09:13 PM t4nk_freenode: lol
09:13 PM t4nk_freenode: a drill press :b
09:13 PM t4nk_freenode: and some connectors
09:13 PM t4nk_freenode: to test
09:13 PM t4nk_freenode: see how small I could go
09:14 PM t4nk_freenode: also an 'ic socket' I ran some tests on
09:15 PM t4nk_freenode: I got some smaller nozzles now, I had .3 on, but I'll wait 'til I got the drill press finished
09:15 PM t4nk_freenode: haven't bothered printing nything else
09:16 PM t4nk_freenode: I just like to _finally_ be able to construct things
09:16 PM t4nk_freenode: lol, and make 'em straight and stuff, it's really a massive improvement
09:17 PM t4nk_freenode: and now I'm mixing printed material with regular material like mdf
09:18 PM t4nk_freenode: it's going steady on with the drill press, I don't want to mess it up... I'm still 'learning' and stumbling on little common problems
09:18 PM t4nk_freenode: so I'm taking my time as not to mess up
09:47 PM t4nk_freenode: getting better at cutting wood by hand now though
09:49 PM t4nk_freenode: and I'm also actually thinking about How to keep things straight ;) never done that before
10:39 PM veegee: hmmm my forklift gasoline engine drawing more fuel than I expect
10:40 PM veegee: The carb is apparently a fixed jet
10:40 PM veegee: Maybe I should convert it to fuel injection
10:50 PM _unreal_: I'd add turbo as well
10:56 PM _unreal_: t4nk_freenode, so when are you going to post some progress photos?
