12:09 AM pink_vampire: XXCoder: we need shipping with drones
12:14 AM XXCoder: rocket powered ones too ;)
12:34 AM pink_vampire: XXCoder: https://www.youtube.com/watch?v=YHvC3KRTxO0
12:34 AM XXCoder: looking
12:34 AM XXCoder: fast indeed
12:35 AM XXCoder: we need WAY more compact and WAY more power packed in batteries
12:35 AM XXCoder: batteries is huge limiting factor
01:55 AM Deejay: moin
01:56 AM veegee: https://www.ckworldwide.com/200-amps-trim-line%e2%84%a2-210.html
01:56 AM veegee: Really? 200A @ 100% duty cycle gas cooled?
01:58 AM veegee: Or does that just mean that the torch itself will be fine, but it'll get too hot to hold?
02:20 AM pink_vampire: XXCoder: https://i.imgur.com/nubnqyr.png
02:20 AM XXCoder: looking
02:20 AM XXCoder: peg board sypport for something?
02:35 AM ok is now known as Guest68452
02:50 AM * Loetmichel is already 2 hours at work. delivery dates... :-(
03:05 AM * Loetmichel is preparing for the mandatory corona masks from monday on in germany... *printing them for half the company* -> http://www.cyrom.org/palbum/main.php?g2_itemId=17785&g2_imageViewsIndex=1
03:06 AM pink_vampire: look nice!
03:06 AM pink_vampire: what mask is that?
03:12 AM Loetmichel: pink_vampire: https://www.thingiverse.com/thing:4235243
03:12 AM pink_vampire: nice!
03:13 AM pink_vampire: Loetmichel: what material did you used to print it?
04:01 AM XXCoder: Tom_L: https://youtu.be/ERdSARw2FdA at 5:28 is different type of hand tap thing
04:02 AM XXCoder: simpler to make too lol
04:08 AM Loetmichel: PLA
04:08 AM Loetmichel: @ pink_vampire
04:13 AM * Loetmichel feels a bit uneasy working at the company alone... just turned a bit of alu into some spacers... would be nice to have a coworker here in case i fu** up.
04:14 AM XXCoder: get elder help system
04:15 AM Loetmichel: ?
04:16 AM XXCoder: you know those portable button you can poress and it calls 911 or whatever your nation number for emergacy is
04:16 AM Loetmichel: haha
04:16 AM Loetmichel: not for a single day of being alone
04:16 AM Loetmichel: was just complaining because boss was supposed to be here with me at 8:00
04:17 AM Loetmichel: now its 11:16, still no boss in sight
04:38 AM Loetmichel: soo, four 15mm by 16mm M6 "washers" done, no body parts lost. now i am a bit more easy alone ;)
04:41 AM XXCoder: :)
05:07 AM pink_vampire: Loetmichel: is it comfortable?
05:26 AM jthornton: morning
05:26 AM Loetmichel: pink_vampire: for a few hours: sure
05:26 AM Loetmichel: wont want to wear it all day though
05:26 AM XXCoder: yo
06:00 AM Tom_L: morning
06:21 AM _unreal_: yawn
06:38 AM Loetmichel: *PHEW* maan those 2mm alu sheets are NOT willing to be bent by hand. Especially when its a 550mm by 550mm doghouse... *sweat* "Hooo-RUCK!" finally done... :-)
06:39 AM Loetmichel: Soo, now i have to countersink 48 more screws, then put the electronics in and i can finally go home... -> http://www.cyrom.org/palbum/main.php?g2_itemId=17788&g2_imageViewsIndex=1
08:49 AM unterhaus: I think latency-histogram might not be totally reliable
08:49 AM unterhaus: is there a way to tell if isolcpu worked?
08:50 AM unterhaus: ran latency test overnight, mostly to see if the system has SMS that kicks in very occasionally
08:51 AM unterhaus: 8700ns on base thread and 4400ns on servo thread, so no problematic sms
09:39 AM andypugh: Interesting: https://youtu.be/utDagouxM5U
10:26 AM jymmmm: andypugh: IT's cool, but seem it would take forever to construct one in a practical sense. With a 20:1 think it has speed or strength in picking things up?
10:27 AM Loetmichel: re at home from work. MAN do i hate that. 9,5h work alone on machines, no break (because i forgot), no food (because i forgot), nothing to drink except water (beacuse fridge is empty)... :-(
10:31 AM jymmmm: Loetmichel: Set alarms on your phone, go buy food.
10:32 AM jymmmm: Loetmichel: Dont wait, dont think about it, just set the alarms like, NOW =)
10:32 AM Loetmichel: jymmmm: usually my coworkers ask "what do you want for lunch today" before they start the oven. i simply forgot
10:33 AM Loetmichel: because i was working on a sunday alone in the company
10:44 AM jymmmm: Loetmichel: I understand, just set the alarms, you can always turn them off =)
11:30 AM skunkworks: http://electronicsam.com/images/greenmachine/IMG_20200426_112519.jpg
11:31 AM Tom_L: that looks nice
11:31 AM Tom_L: so the encoder was a definite plus
11:32 AM skunkworks: yes..
11:36 AM pink_vampire: I have some boring bars here, I need to try it one day
11:36 AM pink_vampire: skunkworks: looks cool!!!
11:37 AM pink_vampire: 4500 ppr on the spindle is ok for that?
11:38 AM skunkworks: I would think that would be decent
11:39 AM skunkworks: I am running 5000 line (20,000 counts per rev)
11:40 AM skunkworks: I think now it is stepper resolution.
11:45 AM sync: nice skunkworks
11:46 AM pink_vampire: do you think HSM support it?
12:09 PM t4nk_freenode: _unreal_ ... I brought a 'drawer slider'? from the hardware store today.. just saw it on the shelves and got curious if I could use them as x and y axes
12:17 PM skunkworks: hsm?
12:25 PM pink_vampire: HSM Works
12:36 PM _unreal_: t4nk_freenode, will work JUST fine. dont expect the tollerance of a liner rail
12:36 PM _unreal_: though
12:36 PM _unreal_: t4nk_freenode, got pictures of the type of draw slide?
12:37 PM _unreal_: there are certain one's that work well just be aware
12:37 PM _unreal_: if it is the type with a bunch of TINY TINY ball bearings that are exposed. you MUST have good dust collection. they get clogged in a heart beat and bind the bearing
12:38 PM _unreal_: t4nk_freenode, if your looking for a simple CHEAP setup that is super strong I'd suggest designing like my system and just make a pipe cnc
12:38 PM _unreal_: very cheap STUPID ruggid
12:40 PM _unreal_: t4nk_freenode, ?
12:47 PM skunkworks: pink_vampire: i dont know yet how this will equate to gcode.. currently setting parameters by motion.analog/digital functionallity
01:01 PM pink_vampire: HSM is a cam software
01:02 PM unterhaus: https://www.tiktok.com/@nickheathsport/video/6811461351639108870
01:05 PM jymmmm: unterhaus: SMH
01:22 PM jymmmm: Fire hardening wood always bugged me... https://arstechnica.com/science/2016/05/turns-out-fire-hardened-spears-arent-as-badass-as-we-thought/
01:26 PM jymmmm: not bugged, but skeptical? And the funny thing I still see it used today, but I don't get it
01:26 PM unterhaus: anyone have a recommendation for a real-time ethernet card?
01:27 PM Tom_L: a mesa card?
01:28 PM unterhaus: trying to decide if I want to get an ethernet mesa card or a low profile mesa card
01:28 PM unterhaus: computer only has one ethernet port, so I'd like to add another
01:28 PM Tom_L: 7i92 or 7i80
01:28 PM Tom_L: oh just add another one
01:29 PM unterhaus: does it matter which chipset on the ethernet card?
01:29 PM Tom_L: i'm not sure. i just grabbed one and installed it
01:29 PM unterhaus: which mesa card do you have?
01:30 PM Tom_L: i test with ^^ both of those and use a 7i90/7i47s combo which is parallel port interfaced
01:30 PM jymmmm: intel ethernet are the best, but whatever you can get you hands on "should" do
01:30 PM Tom_L: if you want the MB inside the cnc control box get a pcie card
01:31 PM unterhaus: I think I'm going to hang the computer outside, but haven't decided yet
01:31 PM Tom_L: cover it from the rain :D
01:32 PM unterhaus: coolant might be more of a concern
01:32 PM Tom_L: mine is a separate mini box
01:33 PM unterhaus: I haven't tested the nuc sized computer for latency yet. I should do that. If that works out okay, it would have to be ethernet
01:33 PM unterhaus: I bought that computer because it had 2 ethernet ports
01:42 PM unterhaus: Can I use any of the ports on a 7i37 as a smart serial port?
01:43 PM t4nk_freenode: _unreal_, https://www.gamma.nl/assortiment/hettich-ladegeleider-type-a-500-mm-max-15-kg/p/B140276 I got this one I think
01:44 PM t4nk_freenode: doesn't have ball bearings; they're more expensive, and it's just a little test after all
01:48 PM t4nk_freenode: I figure if I use for an x or y axis the play won't matter that much since gravity is working too
01:51 PM t4nk_freenode: the only problem might be the extreme position, where it might tip down... but I guess that can be fixed
01:56 PM unterhaus: how will you drive it? A belt might not mind all that slop. A drive screw is going to need compliant mounting
01:57 PM t4nk_freenode: yeah, I see what you mean... it's probably gonna be a screw though, since I'm using stuff I have lyig around
01:58 PM t4nk_freenode: I was wondering how it would behave myself
01:59 PM unterhaus: the good news is those drawer slides are pretty compliant themselves, so it might be okay
02:28 PM skunkworks: seem to have tool interference with the spiral... http://electronicsam.com/images/greenmachine/IMG_20200426_141322.jpg
02:36 PM XXCoder: skunkworks: wonder if you could add torque sensor to spindle see how much its pushing on part when its cutting?>
02:37 PM skunkworks: I can measure power - but it is pretty low currently...
02:37 PM XXCoder: power and torque is bit different though
02:37 PM XXCoder: it may be rotating just fine but still pushing on part really hard
02:38 PM skunkworks: oh - you mean side load
02:38 PM XXCoder: more like along z
02:38 PM XXCoder: if youre adding that, as well as add sideloads too :) along x and y
02:38 PM XXCoder: 3 sensors total
02:38 PM skunkworks: :)
02:39 PM skunkworks: This does look pretty. http://electronicsam.com/images/greenmachine/IMG_20200426_112519.jpg
02:39 PM skunkworks: I just created a rotory shaper.. ;)
02:40 PM XXCoder: wow quite sharp corners for single tool!
02:42 PM XXCoder: normally would need multiple tools to do what you did with one
02:43 PM XXCoder: center drill, drill, bigger drill, endmill, smaller endmill, even smaller endmill, really tiny endmill
02:44 PM XXCoder: you: one cutter. maybe really tiny endmill to clean up afterwards
03:11 PM unterhaus: okay, running 16 bit windows programs on 64 bit windows using vine just cracks me up
03:16 PM unterhaus: some of the drives I have use a 16 bit setup program.
03:16 PM skunkworks: XXCoder: I am running feed per rev...
03:16 PM XXCoder: yeah saw your machine running. aamzing
03:18 PM skunkworks: so .001" initally.. (probably conservative..)
03:21 PM Deejay: gn8
03:38 PM andypugh: skunkworks: Is it quieter with the higher-res encoder>
03:41 PM skunkworks: andypugh: very quiet. other than the thump when it changes direction ;0
05:37 PM XXCoder: jthornton: man its been over a year since I made 3axis_tutorial. been a while
05:49 PM jymmmm: XXCoder: Start with a 1 axis tutorial, then copy and paste 2 times
05:50 PM XXCoder: lol
05:50 PM XXCoder: hardly
05:50 PM XXCoder: https://github.com/LinuxCNC/linuxcnc/tree/master/configs/sim/axis/vismach/3axis-tutorial
06:14 PM jymmmm: XXCoder: This guy chops down a forest and gets a quary just to make the worlds smallest shelter, I just don't get it... https://www.youtube.com/watch?v=quqSfhCQQgQ
06:15 PM XXCoder: looking
06:16 PM XXCoder: banked heat hut
06:16 PM XXCoder: second one closer to tepee
06:16 PM XXCoder: if i spelled that correctly
06:17 PM XXCoder: most of it seem to be just trimming branches. dont really hurt trees
06:17 PM XXCoder: and dead branches on ground
06:17 PM XXCoder: third one heh much work
06:17 PM XXCoder: postive being reusable
06:19 PM jymmmm: XXCoder: Nothing a tarp wouldn't resolve. But, when I saw that huge pile of wood, all I as thinking was... firewood to keep warm all night -shurg-
06:19 PM XXCoder: yeah. i guess it supposes he was lost somewhere and maged to get some gear
06:19 PM XXCoder: like plane crash need to stay place for night
06:19 PM jymmmm: stay in the plane? lol
06:20 PM XXCoder: metal body not good place
06:20 PM jymmmm: cause if you survived a plane crash, that means part of it is still intact
06:20 PM XXCoder: plus plane crash tend to not leave livable space
06:20 PM jymmmm: metal is fine, on ground
06:20 PM XXCoder: stay in car it gets unlivable very fast
06:21 PM XXCoder: it depends on factors I suppose
06:21 PM jymmmm: I see ZERO use for the rocks in that configuration
06:21 PM XXCoder: if you could make a roof and its kinda open but not enough to lose protection from wind you can do it
06:21 PM jymmmm: branches would fige better water protection
06:21 PM jymmmm: give(
06:21 PM jymmmm: *
06:22 PM XXCoder: third one seem to be better for hiding from enemies
06:22 PM XXCoder: he hid the roof
06:22 PM jymmmm: like a thatch roof
06:22 PM jymmmm: I didn't get that for
06:22 PM jymmmm: He's got a saw and nice axe, can't see not having cordage and a tarp
06:22 PM XXCoder: 4th lets see
06:23 PM XXCoder: looks like tree dependant and finding lare amounbt of branches
06:23 PM XXCoder: teepee, large one
06:23 PM XXCoder: no not teepee
06:23 PM XXCoder: cant recall name
06:24 PM XXCoder: using moss and dead stuff for roof
06:24 PM XXCoder: log wall in front of entrance for fireplace and banking
06:24 PM XXCoder: ah and chair lol
06:25 PM XXCoder: 5th type lol he sure likes to make camp places.
06:25 PM XXCoder: slope, rough rocks and junk. lets see. similiar to #3 i bet
06:25 PM jymmmm: I'm still on #2, he likes rocks, almost busted his leg when that rock split
06:26 PM jymmmm: and digging, so many spent calories
06:26 PM XXCoder: yeah
06:27 PM XXCoder: #3 is just huge calories. looks like maybe weeks stay
06:27 PM jymmmm: Now on #3 in the snow
06:27 PM XXCoder: or is it #4 umm confused on order lol
06:27 PM jymmmm: #3 is the first in snow
06:28 PM XXCoder: ah this one is lean-to
06:28 PM XXCoder: good for slope and 3 side protection against wind
06:29 PM jymmmm: coupld of days ago, I head up the mountain to the river. grabbed a fallen tree for firewood, just dragging it over rocks was cumbersome,
06:29 PM XXCoder: yeah #3 is teepee plain one
06:29 PM jymmmm: loved my saw though =)
06:29 PM XXCoder: i simply cant do it lol
06:29 PM XXCoder: my body needs a lot of exercise
06:30 PM XXCoder: and my lungs simply cant get enough oxygen
06:30 PM jymmmm: Great saw... https://www.lowes.com/pd/Corona-RazorTOOTH-10-in-Folding-Pruning-Saw/3006129
06:30 PM jymmmm: best price I've found is $18 at lowes
06:30 PM XXCoder: did you see #4 yet?
06:30 PM jymmmm: not yet
06:31 PM XXCoder: just seeing it makes my back hur
06:31 PM XXCoder: whats chances of stuck at remote spot with that shovel
06:31 PM jymmmm: oh #3 is a teepee in the snow
06:31 PM XXCoder: i find it funny he goes out and be primitive with modern steel tools
06:32 PM jymmmm: #4 is him digging on a hillside???
06:32 PM XXCoder: i like other one better. actually "primitive" supposing savage knows what we know.
06:32 PM XXCoder: yep!
06:32 PM XXCoder: only huge major backbreaking compared to other 5
06:33 PM jymmmm: Makes me think some war hidden hunker thingy
06:33 PM jymmmm: bunker*
06:33 PM XXCoder: jymmmm: https://youtu.be/wrTDJbaxhOI turn on captions! he never speaks in video but talks a lot in caprions
06:33 PM jymmmm: it's as tall as he is
06:34 PM jymmmm: Oh yeah, he puts EVERYONE to shame =)
06:34 PM XXCoder: video i linked to is amazing. he starts with NOTHING
06:34 PM XXCoder: not like that guy with shiny steel ax and shovel
06:35 PM XXCoder: well not QUITE nothing
06:35 PM XXCoder: he wears a shorts. thankfully
06:43 PM unterhaus: well, the rtai kernel didn't like running on the celery 3152
06:45 PM jymmmm: XXCoder: Oh, he has a book out... https://www.amazon.com.au/dp/1529105838
06:52 PM unterhaus: I don't know about making bricks, but I want to make a fire with sticks
06:57 PM jdh: pretty simple.
06:57 PM jdh: make a pile of sticks, through some gasoline on them, toss a match.
07:04 PM jdh: the PocketCNC videos looks surprisingly good given the work envelope
07:10 PM XXCoder: yeah he got book
07:10 PM XXCoder: jdh: yeah expensive though ouch'
07:10 PM XXCoder: 5k something I thinkl
07:11 PM XXCoder: 581 ratngs DANG!!
07:11 PM JavaBean: must be nice to be able to just buy a 5+k cnc for home use
07:11 PM XXCoder: yeah'
07:11 PM XXCoder: he runs a lathe too
07:12 PM jdh: $8.5k with high speed spindle.
07:13 PM XXCoder: fancy
07:13 PM jdh: a little cheaper than a (3 axis) tormach, but not much.
07:15 PM JavaBean: too expensive for a "normal" person
07:16 PM XXCoder: yeah
07:16 PM JavaBean: i wonder what the "chinesium" options are running
07:17 PM XXCoder: i dont know of any chinesium if pocketnc
07:18 PM JavaBean: and now that i am asking, my fsck'n datacap won't let me look
07:18 PM XXCoder: lots items use pocketnc name lol
07:18 PM XXCoder: including cpuple of umm sex toys
07:19 PM JavaBean: well, yeah
07:19 PM XXCoder: found 800-1500 usd 5 axis
07:19 PM XXCoder: https://www.aliexpress.com/item/32735546699.html
07:21 PM JavaBean: its an "engraver"...
07:21 PM XXCoder: yeah
07:25 PM JavaBean: ha, a 6040 for double the price
07:26 PM JavaBean: https://www.aliexpress.com/item/32866373581.html
07:27 PM XXCoder: https://taigtools.com/product/micro-mill-2018cnc/
07:27 PM XXCoder: micro mill
07:28 PM XXCoder: https://taigtools.com/wp-content/uploads/2018/11/Mill-Parts.jpg i wonder how asy it is to swap parts with 2020 2040 etc and use ballscrews
07:28 PM XXCoder: also mgn rails
07:28 PM XXCoder: probably can do it under 1000 usd
07:56 PM unterhaus: I could build a pretty nice router out of my junk pile, but I got no room for it
07:57 PM XXCoder: i already HAVE a router
07:57 PM XXCoder: no room for it to actually run
08:06 PM unterhaus: what do you have?
08:07 PM XXCoder: oh chineseium 3040 something
08:13 PM JavaBean: be nice to find one for a good price that you don't have to "suck off" customs just to get it to your door
08:15 PM XXCoder: i live at usa. no small scale customs
08:17 PM JavaBean: i live in the us as well, and close enough to the mexican border.. and now one of their "checkpoints" that are nominally in the us... they aren't a joke, a joke is funny. they are a fraud that steals billions of dollars of tax-payer money
08:17 PM XXCoder: :(
08:20 PM JavaBean: you hear about how much "drugs" they catch at these checkpoints?? its fraud, in order to prosecute it has to be more than quarter ounce (or maybe quarter pound, can't remember with certainty)... the local court that prosecutes tell this to jurors, like its just a joke. 'ignore how much they wrote down as seizing, it has to be more than X before we can prosecute'
08:22 PM JavaBean: they pay the "local court/jail" untold millions of dollars a year to keep taking these cases... until the budget runs out, then they abandon the checkpoint until they can get more money to pay out
08:22 PM jdh: "they"?
08:23 PM JavaBean: they= Customs and Border Protection
08:24 PM XXCoder: odd
08:25 PM XXCoder: sounds like just pure scam
08:31 PM JavaBean: since they are also the ones that drive the US/Mexico border, they do have a purpose. but yeah, these "checkpoints" within the us they have setup?? poor fraud
08:32 PM JavaBean: s/poor/pure
08:34 PM XXCoder: why isnt people fighting back
08:35 PM JavaBean: they lost a few years ago...
09:23 PM unterhaus: every time I buy more zip drives I loose some of them
09:23 PM XXCoder: just tighten em up
09:24 PM unterhaus: dang, I hate that, lose. This time it's an impressive 4 out of 5
09:25 PM XXCoder: geez
09:25 PM unterhaus: I bought 5 thinking if I lose one or 2 it won't be so bad.
09:26 PM Tom_L: if you get too many you will forget what you put on which
09:28 PM XXCoder: easy enough, buy way more, and label them ;)
09:32 PM unterhaus: I like the metal kingston ones, but last time I looked they only had 32gb, which is too big
09:33 PM XXCoder: too big?
09:33 PM Tom_L: won't fit in his pocket
09:33 PM unterhaus: and too expensive since I'll probably lose them
09:34 PM unterhaus: it's a bit silly to put an iso on a 32gb flash drive, which seems like the main thing I do nowadays
09:43 PM _unreal_: zip drives??
09:43 PM _unreal_: do they still make them?
09:56 PM unterhaus: how do you load a new system, ethernet boot?
09:56 PM _unreal_: t4nk_freenode, ya it will likely have a lot of play but for a basic system just to get started will work
09:56 PM _unreal_: :/
09:56 PM _unreal_: t4nk_freenode, as I said you would be better off getting cheep pipe and making a small pipe machine. and follow my bearing design. not expensive and very rigid
09:57 PM unterhaus: I'm doing some work for someone and he gave me a computer running winxp to use. I didn't want it on my network so I used zip drives to move anything to it
09:57 PM _unreal_: why a zip drive rather then a thumb/flash drive?
09:57 PM _unreal_: slow old tech prone to problems
09:57 PM unterhaus: same thing
09:57 PM _unreal_: and was fucking amazing back when they were new
09:58 PM * Tom_L hugs his dos6.22 bootable floppy
09:58 PM unterhaus: you're being too literal, some people like me call flash drives zip drives
09:58 PM unterhaus: I have a whole lot of floppy discs still.
09:59 PM unterhaus: not sure if I have a drive that works though
09:59 PM _unreal_: ya I got a crap load of floppys as well all stowed away
10:00 PM unterhaus: I used to ride my bike past the iomega headquarters occasionally
10:01 PM unterhaus: I never used one of their drives, but I threw one away recently
10:01 PM _unreal_: nothing said zipdrive like the click of death
10:01 PM _unreal_: tick tick tick tick tick tick tick titititititit tick tic
10:02 PM unterhaus: yeah, I'm pretty sure my boss had one go bad
10:15 PM unterhaus: rt-preempt on the celery had a real-time error when I opened a website
10:15 PM unterhaus: too bad the rtai kernel locked it up
10:25 PM Tom_L: what os?
10:29 PM unterhaus: mint
10:30 PM unterhaus: 19.2
10:30 PM Tom_L: did it install ok?
10:30 PM unterhaus: I just got the iso
10:30 PM Tom_L: https://gnipsel.com/linuxcnc/uspace/linuxmint19-rt.html
10:32 PM unterhaus: I'm trying out computers to decide which one to use, so I don't want to actually install it on an SSD
10:32 PM Tom_L: i see
10:32 PM unterhaus: want to use the celeron though, so I might see if I can find an rtai kernel that works
10:33 PM Tom_L: good luck with that
10:33 PM Tom_L: i've been trying to build one all evening
10:33 PM unterhaus: been a long time since I built a kernel, but I used to do it all the time because we had some weird processors in the embedded systems I bought
10:34 PM Tom_L: i don't make a habit of it
10:34 PM unterhaus: not sure I have ever built an RTAI kernel. Used to build realtime linux kernels pretty often
10:34 PM unterhaus: not a fan of patching
10:35 PM unterhaus: maybe I should go fiddle with the bios settings to see if there is something that needs to change
10:35 PM Tom_L: turn off hyperthreading
10:36 PM unterhaus: anything else?
10:36 PM Tom_L: probably but i forget
10:36 PM unterhaus: heh
10:36 PM Tom_L: anything 'fancy' like that
10:47 PM unterhaus: it clearly goes out to lunch very quickly
10:47 PM Tom_L: try the stretch iso
10:47 PM unterhaus: Tom_L, what kernel are you trying to build?
10:48 PM Tom_L: rtai 5.2
10:48 PM unterhaus: stretch ISO is a good idea, if I could only find a flash drive
10:48 PM Tom_L: they're trying to keep rtai alive on stretch and buster but it's having it's issues
10:50 PM unterhaus: stretch iso is rt-preempt, don't think it will get me anywhere
10:50 PM Tom_L: you think you gotta run rtai?
10:51 PM Tom_L: i'm running wheezy on my mill
10:51 PM unterhaus: the rt-prempt on this computer was horrible.
10:52 PM unterhaus: although I just turned off energy management, so maybe I should try again
10:52 PM Tom_L: did you check after adjusting the bios settings?
10:52 PM unterhaus: trying again
10:59 PM unterhaus: not that good, 300 microseconds
11:00 PM unterhaus: at least it didn't have a real time error
11:00 PM Tom_L: what video card?
11:00 PM Tom_L: can you swap that?
11:00 PM Tom_L: and disable onboard video
11:08 PM flyback: what are you trying to do
11:08 PM flyback: btw there is also sgabios
11:09 PM flyback: if you don't need video output
11:09 PM flyback: emulates text real mode video and keyboard over serial
11:09 PM flyback: you can flash it to a video card bios or anything else with a bootrom
11:09 PM flyback: might put that on my one dell poweredge that doesn't have a bmc and serial over lan
11:10 PM unterhaus: this computer is like a nuc, nothing can be changed
11:10 PM flyback: caw-nuc?
11:11 PM flyback: what's the problem anyways
11:11 PM flyback: and what board
11:11 PM flyback: why the hell are you using zip drives
11:11 PM flyback: they self destruct
11:11 PM flyback: and the damaged media breaks new drives you put them in
11:12 PM flyback: oh and speaking of
11:12 PM flyback: I waited a month for all this shit I ordered on amazon
11:12 PM flyback: and the ch341 programmer has no labeling on the ic
11:12 PM unterhaus: https://www.amazon.com/gp/product/B0179S50UU/ref=ppx_yo_dt_b_asin_title_o04_s02?ie=UTF8&psc=1
11:13 PM flyback: apprentely they were too cheap to use a real chip for 20 cents
11:13 PM flyback: dude that's nice
11:13 PM flyback: intel hd graphics aren't bad for non gaming
11:13 PM flyback: I got bad news though
11:13 PM unterhaus: it's actually nice to use as a desktop, reasonably quick
11:13 PM flyback: Intel N3160 Quad Core
11:14 PM flyback: atom soc that loses it's lpc clock after a year
11:14 PM flyback: can no longer boot
11:14 PM flyback: known silicon defect
11:14 PM flyback: ended up in routers and nas's costing $1000's
11:15 PM unterhaus: it's a celery, not an atom
11:15 PM flyback: no
11:15 PM flyback: that's a celly based on atom
11:15 PM JavaBean: its an intel part, as such its bad to have these days
11:15 PM unterhaus: I've had it for 4 years now with no issues
11:15 PM flyback: braswell which is a atom soc
11:16 PM flyback: you lucked out or they used a lower voltage bootrom
11:16 PM flyback: which doesn't degrade
11:16 PM flyback: the clock
11:16 PM Tom_L: nuc nuc
11:16 PM unterhaus: dunno
11:16 PM flyback: the fix at least on synology is just a 100k pullup or down
11:16 PM flyback: can't rmember
11:16 PM Tom_L: maybe this round has a dying arse chance of building..
11:17 PM flyback: unterhaus, https://en.wikipedia.org/wiki/Silvermont
11:17 PM Tom_L: how do you turn ipipe back on?
11:17 PM flyback: https://en.wikipedia.org/wiki/Silvermont#Erratum
11:17 PM flyback: translation:
11:18 PM * flyback beats ruemohr against intel's erratum
11:18 PM flyback: also lose the sd reader as well
11:19 PM flyback: and usb
11:19 PM flyback: appears their cmos process just couldn't handle 3.3v logic
11:20 PM flyback: my new chomebook I lucked out
11:20 PM flyback: x5-e8000 embedded version of braswell was a new stepping
11:21 PM flyback: for a while you could get $1000 synology for $50 on ebay or free
11:21 PM flyback: once the fix was known the prices shot up
11:22 PM flyback: although the 2 disk nas's are cheap
11:22 PM flyback: I might get one
11:24 PM unterhaus: so I guess booting from a usb drive is not a good idea
11:25 PM flyback: it might be ok
11:25 PM flyback: I htink the usb 2.0 and 3.0 are affected differentely
11:28 PM unterhaus: not sure what to do with it since it doesn't boot rtai and the rt-preempt performance is horrible
11:28 PM flyback: what happens when you try to boot rtai
11:28 PM unterhaus: it goes dead
11:29 PM flyback: hmm
11:29 PM flyback: did you try switch the bios from uefi to legacy etc
11:29 PM flyback: and try updating the bios to latest
11:30 PM unterhaus: I don't remember seeing a uefi option. Bios update is a good idea if it stops it from bricking itself
11:30 PM flyback: yeah it is
11:30 PM flyback: coreboot might be an option also I dunno
11:31 PM Tom_L: unterhaus, what rtai are you trying?
11:32 PM Tom_L: iirc you said you're using mint 19.2?
11:35 PM unterhaus: I am using the rtai iso that got taken down off of the forum
11:35 PM unterhaus: 19.2
11:35 PM Tom_L: the one andy was working on?
11:35 PM unterhaus: no
11:36 PM unterhaus: beaglebrainz, I think
11:36 PM unterhaus: I didn't understand the issue why he took it down, seems to run fine on i5's
11:37 PM unterhaus: be a little complicated to see what kernel version rn
11:38 PM Tom_L: https://github.com/andypugh/RTAI
11:38 PM Tom_L: if you care to build one
11:45 PM Tom_L: https://github.com/NTULINUX/RTAI/releases
11:45 PM Tom_L: or that one
11:45 PM Tom_L: which is probably the one andy is using
11:45 PM unterhaus: so I have to build linuxcnc from source as well?
11:46 PM Tom_L: probably for that yes
11:46 PM Tom_L: i'm gonna try it in the next few days i think
11:47 PM unterhaus: are you going to try the ntulinux or andypugh repository?
11:47 PM Tom_L: ntulinux i think
11:48 PM Tom_L: or both
11:48 PM unterhaus: seems like they have been messing around since october?
