01:14 AM Loetmichel: Jymmm: i am now
01:19 AM pink_vampire: hi Loetmichel
01:40 AM Deejay: moin
02:29 AM veek: comrade sync, are you awake?
02:29 AM veek: i just got neutered in highly capitalist negotiations
02:30 AM * veek sheds a tear for what might have been
03:03 AM pink_vampire: Any idea how to prevent chips from accumulating in to the band saw body?
04:16 AM pink_vampire: no one here
04:18 AM Loetmichel: of copurse not... all bots idling ;)
04:21 AM pink_vampire: O_o
04:21 AM XXCoder: heys
04:22 AM pink_vampire: hi XXCoder
04:22 AM XXCoder: whats up super awesome machinist
04:22 AM pink_vampire: cleaning my band saw
04:23 AM pink_vampire: how glitters are made https://i.imgur.com/ejYCLdj.png
04:23 AM XXCoder: lol
04:23 AM XXCoder: those is better than glitter, glitter damage the envorment
04:24 AM XXCoder: buy some from culturehustle if you want plant based glitter
04:24 AM pink_vampire: I need to fined a name for my band saw
04:24 AM pink_vampire: I'm fine with the cheapest acrylic paints from walmart.
04:26 AM XXCoder: not paint, glitter powder heh
04:27 AM pink_vampire: I have more then I ever wanted in chips
04:28 AM XXCoder: i saw some cool epoxy chips projects
04:28 AM XXCoder: can even re-mill em into letters or something, then re-coat with epoxy for safety
04:29 AM pink_vampire: not sure how to even start working with epoxy
04:29 AM XXCoder: dunno havent done em myself
04:30 AM pink_vampire: I need large ruby ball. about 1" diameter
04:30 AM pink_vampire: or something similar
04:31 AM pink_vampire: maybe to cast it from epoxy is the way to go?
04:33 AM XXCoder: hmm issue is precision of such thing
04:34 AM pink_vampire: it is for art
04:34 AM XXCoder: ahh ok
04:35 AM pink_vampire: I think I'm a little obsessed with ruby sphere. probing, CMMs, digitizing and stuff like that.
04:36 AM pink_vampire: spheres *
04:36 AM XXCoder: :D
04:43 AM howto: good day folks
04:43 AM howto: which of you good people know how to install and use smictrl in wheezy distro?
04:44 AM XXCoder: hey
04:44 AM XXCoder: not me unfortunately
04:45 AM howto: and of course willing to help me...that is the most important part :))
04:45 AM XXCoder: not me unfortunately
04:45 AM XXCoder: kidding ;)
04:47 AM howto: so what do i do? and how do i proceed?
04:48 AM howto: i have 200.000 nanoseconds in latency test....and want to lower that number
04:49 AM howto: XXCoder you know anything about how to proceed in this matter?
04:50 AM XXCoder: some of it
04:50 AM XXCoder: disable power saving everything in bios
04:50 AM howto: done allready
04:50 AM XXCoder: there is something else there hmm
04:50 AM howto: hyperthreading...disabled that too
04:50 AM XXCoder: you already using video card that was in its era, gaming video card?
04:50 AM XXCoder: if so, also disable onboard video
04:51 AM howto: i am on activated optimus and commuted on the integrated one...that got me about 190.000 nanosecods
04:51 AM howto: disabled network card too
04:51 AM rmu|w: howto: what board is this
04:51 AM howto: still around 190.000 nanoseconds
04:52 AM howto: what do you mean?
04:52 AM howto: can hwinfo provide that info?
04:52 AM rmu|w: howto: what mainboard / cpu
04:54 AM howto: ok....what command do i type in terminal for that? :)))
04:55 AM howto: sysinfo give me info about he cpu its a second gen corei7 2820qm
04:56 AM rmu|w: howto: dmidecode could give you that info, or a look under the hood
04:57 AM rmu|w: optimus sounds like notebook. don't.
04:58 AM howto: if you enable it will deactivate the mxm video card
04:58 AM Loetmichel: Indeed. most notebooks make extensive use of power saving features that mess with the latency... as you noticed
04:58 AM howto: on linux although the bios says that only windows os are affected....a bunch of liars as usual :))
04:58 AM rmu|w: howto: don't use a notebook
04:59 AM howto: way to expensive to give up on it now...if smictrl gig can solve the problem i'm up for it
05:00 AM howto: motherboard is a precision m6600
05:03 AM rmu|w: so now that you have been warned, what is the issue with smictrl?
05:04 AM howto: how to compile it how to enable it so i can shave some nanoseconds on this laptop inlatency test?
05:06 AM rmu|w: git clone git://git.kiszka.org/smictrl.git smictrl
05:06 AM rmu|w: cd smictrl
05:06 AM rmu|w: make
05:08 AM howto: are these commands needed to be issued in the distro itself or just on the same computer? now i am writting from an ubuntu boot
05:08 AM rmu|w: there seems to be another version in the linuxcnc wiki: http://wiki.linuxcnc.org/uploads/smictrl.c
05:08 AM howto: do i have issue the from wheezy?
05:09 AM howto: what do i do with it i am not a terminal wiz here :))
05:10 AM rmu|w: howto: you could probably build it in ubuntu, but you have to run it on the OS you are using for linuxcnc, rebooting probably resets everything
05:11 AM XXCoder: whats you controlling using it anyway
05:11 AM XXCoder: is it BOB with stepper controllers, or MESA or whateber
05:12 AM rmu|w: if you look at the link http://wiki.linuxcnc.org/uploads/smictrl.c it comes with build-instructions in the comments
05:12 AM howto: it is is a stepfourbasic 540 on a parallel port on the laptops dockin station
05:12 AM XXCoder: biggest latency source is unfortunately laptop itself
05:12 AM XXCoder: its structured different so its hard to lower latency.
05:13 AM XXCoder: while its easy to get 30k or 40k with older computer
05:13 AM howto: but if smictrl manages to lower those numbers atleast will be something
05:22 AM howto: some erros occured more like this one
05:22 AM howto: smictrl.c:(.text.startup+0x179): undefined reference to `pci_alloc'
05:23 AM howto: for about 9 files
05:23 AM howto: the last one is
05:23 AM howto: ld returned 1 exit status
05:24 AM howto: is it beacause i am not in the wheezy ?
05:24 AM rmu|w: howto: what exactly did you do
05:24 AM howto: took the last smi ctrl.c file you gave me put it in a folder
05:24 AM rmu|w: howto: do it in wheezy
05:25 AM howto: executed the commands in the smictrl.c commentary for compiling
05:25 AM JT-Cave: morning
05:26 AM howto: i supose i did something wrong here...do i need only the smictrl.c ? or i need some other files too in that folder?
05:26 AM XXCoder: hey jt
05:26 AM rmu|w: howto: can you paste the complete output into some pastebin
05:27 AM rmu|w: howto: try this cc -O2 -Wall -I $KSRC/include smictrl.c -lz -lpci -o smictrl
05:28 AM howto: its the same error a few times only for more files
05:28 AM howto: rmu|w its the same command i gave in terminal by the letter
05:29 AM rmu|w: howto: -lz -lpci has to come after smictrl.c
05:29 AM howto: oops....sorry
05:29 AM howto: doing that
05:30 AM howto: heey no errors
05:30 AM howto: and we have a file without an extension
05:30 AM rmu|w: ferpect
05:30 AM howto: what do i do with it? :|
05:30 AM rmu|w: ./smictrl
05:32 AM rmu|w: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?FixingSMIIssues
05:32 AM howto: so i take this file in the wheezy distro execute that command and do a latency test? or what?
05:33 AM howto: dont i need to change some permissions or something?
05:33 AM rmu|w: howto: build it again in wheezy
05:33 AM rmu|w: howto: you need to give it some arguments, can't help there
05:33 AM howto: ok
05:34 AM howto: and after i execute it i should see some improovments?
05:34 AM rmu|w: possibly
05:36 AM howto: so no options for the command? i heard there are some options
05:37 AM rmu|w: with a laptop, expecially an old one with potentially aged heat pipes, clogged ventilation and generally bad cooling, all bets are off
05:37 AM howto: to go with it
05:37 AM howto: mine has completely clean coolers :)
05:37 AM howto: a ccoling pad under it for a good measure
05:38 AM howto: and seems to overheat in dell's normal parameters :))
05:39 AM howto: so i expect 100% success on this
05:39 AM rmu|w: smictrl will output help, but i have no idea what to do with it
05:41 AM howto: well it's a start...i didnt say i want to use the cnc this year either did i? :)))
05:45 AM rmu|w: miracles do happen, but maybe you have already used your free one on keeping 12 year old dell laptop running
05:45 AM rmu|w: oups. 8 years.
06:18 AM howto: no joy folks cant instal pci-dev on wheezy with apt-get
06:18 AM howto: without it cant compile smictrl
06:19 AM howto: any easy way to istall pci-dev +dependencies on wheezydistro?
06:20 AM JT-Cave: Сергей Кравцов has sent you a message regarding the payment they made to you on April 5, 2020. They also indicated they did not receive the merchandise.
06:20 AM JT-Cave: here we go again, I'm going to have to pay for a lost shipment
06:22 AM XXCoder: jeez
06:22 AM howto: JT maybe you should go to double-you double-you double-you team viewer dot com to sort out the matter
06:22 AM howto: :))))
06:22 AM JT-Cave: $450!!!
06:23 AM JT-Cave: well I don't ship to poland or russia any more I'm tired of that crap
06:23 AM howto: and have all your accont information ready when asked for too:)
06:23 AM howto: otherwise they cant steal ....i mean recover their money from you can they? :)
06:24 AM JT-Cave: paypal will refund his money from my account
06:24 AM howto: JT how to install libpci-dev from a distro that refuses to install beacause it is EOL?
06:25 AM howto: without it i cant compile smictrl on the distro itself
06:25 AM howto: anyone?
06:27 AM JT-Cave: often eol libs will be moved to a different location so you would have to find them and change the location
06:29 AM tiwake: how are custom macros made with the fanuc controller?
06:29 AM tiwake: I was reading somewhere where numbers could be passed to the code, but it did not elaborate
06:31 AM tiwake: made a broaching program, needs 6 numbers...
06:32 AM tiwake: oh, and is there a way to get the current tool's position?
06:38 AM tiwake: if I could get the tool's current position then I would need one less variable... heh
06:39 AM jymmmm: Good morning
06:40 AM tiwake: (hi)
06:42 AM tiwake: found this https://www.practicalmachinist.com/vb/attachments/f21/209155d1506882605-fanuc-macro-system-variables-about-axis-position-macro-coordinates.jpg
06:43 AM jymmmm: JT-Cave: excluding those countries, but why not REQUIRE shiping insurance for international destinations?
06:44 AM jymmmm: JT-Cave: or some such thing
06:44 AM methods_: $10,000 russian bear insurance
06:44 AM JT-Cave: even better just stop shipping to unreliable countries
06:46 AM methods_: due to your country being full of criminals i no longer ship to it
06:46 AM tiwake: so #5041 through #5048 is the current position of the tool after all offsets and workshift?
06:46 AM jymmmm: JT-Cave: REGISTERED mail, just to CYA
06:46 AM jymmmm: anything over $20
06:46 AM JT-Cave: jymmmm, I just don't ship to those countries any more
06:47 AM JT-Cave: it's not worth the hassle for me
06:47 AM jymmmm: JT-Cave: all other countries are okey?
06:47 AM jymmmm: CaptHindsight: ty
06:48 AM jymmmm: I've had AU take 6 months before, twice actually
06:48 AM JT-Cave: dunno I only ship to a few countries now
06:48 AM JT-Cave: I have one package stuck in customs for a month now to AU
06:49 AM jymmmm: AU can be weird to ship to sometimes
06:52 AM JT-Cave: maybe I should just stop shipping and close the business down
06:53 AM tiwake: methods_: do you know?
06:54 AM XXCoder: my worse period was year to cross from usa to usa
06:55 AM XXCoder: box was quite dusty lol corners dunged
06:55 AM jymmmm: Buhahahaha... https://www.amazon.com/gp/customer-reviews/RNAUPENE0LUH/
06:57 AM jymmmm: I never knew that kapton tape resolved drinking problems... the more you know
06:57 AM tiwake: thats kinda funny
07:07 AM jymmmm: tiwake: :)
07:13 AM methods_: tiwake: sorry no idea on that one
07:14 AM tiwake: hmm
07:14 AM tiwake: methods_: who would?
07:16 AM methods_: no idea it should say in the docs somewhere i would think
07:17 AM methods_: 5420-5428
07:17 AM methods_: Current Position including all offsets and in the current program units for X, Y, Z, A, B, C, U, V & W, volatile.
07:17 AM methods_: https://forum.linuxcnc.org/38-general-linuxcnc-questions/28307-system-variable-for-current-z-machine-position
07:18 AM rmu|w: howto is gone?
07:18 AM rmu|w: http://archive.debian.org/README
07:19 AM tiwake: hmm
07:20 AM methods_: that thread has quite a bit of info in it on position variables
07:20 AM tiwake: what about making custom G-command and passing variables to it?
07:21 AM methods_: well that is certainly possible
07:21 AM methods_: http://linuxcnc.org/docs/html/remap/remap.html
07:22 AM methods_: http://linuxcnc.org/docs/html/remap/remap.html#_creating_new_g_code_cycles
07:22 AM tiwake: or wait, is that for linuxCNC or fanuc?
07:22 AM methods_: linuxcnc
07:23 AM methods_: you want fanuc?
07:23 AM tiwake: yeah :(
07:23 AM methods_: oh sorry didn't see that
07:23 AM tiwake: my work does not have any linuxCNC machines
07:23 AM methods_: yeah sorry just read up
07:24 AM tiwake: they are all new shitty machines made by hyundia (or however its spelled)
07:24 AM methods_: it depends on the controller and machine
07:24 AM methods_: a lot of machine makers don't necessarily follow the same param locations
07:24 AM methods_: but yes you can make macros and feed those params to them
07:25 AM methods_: https://www.amazon.com/Fanuc-Custom-Macros-Peter-Smid/dp/0831131578
07:25 AM methods_: i used to use that book when i programmed with macros
07:25 AM methods_: however i quit using them because the operators would complain that they couldn't figure out what the program was doing
07:26 AM methods_: the macros almost inevitably caused more problems than they solved once operators got involved
07:26 AM tiwake: how? pass the numbers correctly and everything just works
07:27 AM tiwake: probably quite a bit simpler than using a threading cycle with fanuc... heh
07:28 AM methods_: yes pass the variable like any other number
07:29 AM methods_: http://www.machinetoolhelp.com/Applications/macro/threading_macro_g76.html
07:29 AM tiwake: I think there is a way to do something like G101 X[number] Z[number] Q[number] R[number] where those are picked up in the macro... somehow
07:30 AM methods_: http://www.machinetoolhelp.com/Applications/macro/Variable_peck_drilling_cycle.html
07:30 AM methods_: well a canned cycle like g101 is a macro
07:31 AM methods_: somewhere in the controller is the program for g101 probably in a block of hidden programs
07:31 AM methods_: you will need to unlock those programs to see them and edit them
07:32 AM methods_: all the g and m codes on your machines are "macros"
07:33 AM tiwake: sure... I just mean defining one that was not defined before
07:33 AM howto: managed to install library but got the following errors
07:33 AM howto: cc: error: unrecognized command line option ‘-r/source/include’
07:33 AM howto: cc: error: lpci: No such file or directory
07:34 AM methods_: https://www.pmpa.org/docs/technical-conference/cnc-programming-workshop.pdf
07:37 AM tiwake: ooo
07:37 AM methods_: tiwake: that last link looks to be fairly comprehensive but still worth getting the macro book
07:38 AM methods_: if you plan on doing lots of macro programming
07:39 AM methods_: pg65 on that last link goes over position vars
07:43 AM jymmmm: Hmmm what could you do with 37Farad 2.7V caps???
07:43 AM howto: blow up resstors LED's and other stuff? :)
07:45 AM jymmmm: howto: it's 37 Farad, not uF
07:45 AM tiwake: get a few more and make RAIL guns?
07:46 AM jymmmm: tiwake: 30 of them
07:46 AM tiwake: do it
07:46 AM jymmmm: tiwake: got a link to a circuit?
07:47 AM tiwake: its just capacitors and the rails... maybe get fancy and add a switch?
07:47 AM Loetmichel: *HU*? just went out for a smoke, looked at my car (BMW E46 convertible) "Why the F*** is my ragtop closed? I definetly parked it open?!?" Coworker:"yeah, normal... thats because you have so much clutter in your poket, it can open/close the windows AND the ragtop when you press and hold the lock/unlock buttons on the key"... interesting, didnt knew that that feature exists. :-)
07:48 AM methods_: yeah can be a real problem on a rainy day
07:48 AM methods_: when you come out and your car is a fish tank
07:48 AM tiwake: my car is all manual stuff
07:48 AM methods_: you should be able to disable that feature
07:49 AM tiwake: manual roll down windows, manual transmission, manual locks...
07:49 AM methods_: well you don't have to worry about coming out to your car full of rain water unless you left your windows down lol
07:50 AM jymmmm: tiwake: Bah, requirs hight voltage, these are only 2.7V
07:50 AM jymmmm: mozmck: unless all the junk in his pockt holds down the unlock button
07:51 AM Loetmichel: methods_: it would be sufficient to not put the car key in the same jeans pocket as ~12 thumbdrives, 2 cigarette lighters and some other stuff :-)
07:54 AM methods_: Loetmichel: that might work too :p
07:54 AM methods_: sounds like you need a fanny pack
07:55 AM Loetmichel: methods_: THATs the usual contents of my trousers pockets. Questions? -> http://www.cyrom.org/palbum/main.php?g2_itemId=15868&g2_imageViewsIndex=1
07:55 AM methods_: https://images-na.ssl-images-amazon.com/images/I/611pSGp4TdL._AC_SY355_.jpg
07:56 AM Loetmichel: if you put a BMW key in there... (old sty, no keyless crap...)
07:56 AM Loetmichel: on top of all that :-)
07:56 AM JavaBean: Loetmichel: thats all you keep in your pockets??? i would be missing soo many things....
07:56 AM methods_: i don't even know what to say
07:57 AM methods_: that is a lot of shit to carry in your pockets
07:57 AM Loetmichel: JavaBean: smartphone and leatherman are on the belt ,)
07:57 AM * JavaBean is glad he doesn't have a site he can post 'pocket dumps' too
07:58 AM JavaBean: smartphone is on belt, leatherman in pocket
08:02 AM Loetmichel: JavaBean: http://www.cyrom.org/palbum/main.php?g2_itemId=17871&g2_imageViewsIndex=1
08:02 AM Loetmichel: (MAN do i have a belly lately...)
08:02 AM Loetmichel: :-)
08:03 AM tiwake: methods_: that is a really good PDF BTW...
08:05 AM JavaBean: meh, how many times have you broken that phone?? i have a "milspec" durable smartphone, it and its holster are oft ripped off my belt. don't ask how many times i have accidentally "dropkicked" either or both across a room... nor how many times it has slid off a roof
08:06 AM methods_: tiwake: yeah looks pretty comprehensive hopefully it helps
08:06 AM tiwake: it has so far
08:06 AM tiwake: maybe it has all my questions
08:07 AM tiwake: 1/3 through it
08:07 AM Loetmichel: JavaBean: NEVER
08:07 AM Loetmichel: not even once
08:08 AM Loetmichel: still original Samsung Note 3
08:08 AM Loetmichel: and thats OLD
08:08 AM Loetmichel: before that rips off my belt the aluminium will probably cut the belt in half
08:09 AM JavaBean: ah, yes... wasn't thinking about it being in an alu "holster"
08:12 AM JavaBean: mine is in a "canvas" holster, but thats because they are cheaper to replace. since my holster is often torn off, its less painful when i "dropkick" that than it would be if the holster was alu
08:13 AM Loetmichel: that holster is selfmade
08:14 AM Loetmichel: the "clip" on the back is a loop, srewed on with 4 M3 screws... that WILL NOT rip off, it will cut the belt before it does
08:14 AM JavaBean: mine isn't, yet... but that's because i haven't started working with leather... thanks corona-chan
08:14 AM Loetmichel: the reason why the phone looks so scratched is that i tend to take corners a bit cose
08:15 AM Loetmichel: the steel door frames here at the company have loads of scratches at hip hight for a reason ;)
08:15 AM JavaBean: considering how often my "holster" gets ripped off in electronic/electrical enclosures... i will have to stay away from alu
08:16 AM JavaBean: my house and my "Workplace" also have loads of scratches at hip height... my
08:16 AM JavaBean: "canvas" holster is often "filled" with steel shavings
08:17 AM Loetmichel: oh, yes, alu and hig power enclosures dont mix well ;)
08:17 AM JavaBean: atleast in the seams
08:17 AM Loetmichel: i am with you there ;)
08:48 AM * JT-Cave wonders if there is an OS for the Raspberry pi that doesn't suck
08:49 AM Loetmichel: JT-Cave: ubuntu is pretty useable if you switch to xfce
08:52 AM JT-Cave: I tried ubuntu using the rpi installer and it boots up to a terminal so I think it's the server as it makes you use an obfuscated password
08:53 AM JT-Cave: if you know of a desktop ubuntu that is rpi a link would be nice
08:53 AM Loetmichel: as i said: you can install the desktop. not that much of a problem as far as i remember
08:54 AM JT-Cave: https://www.raspberrypi.org/downloads/raspberry-pi-os/
08:54 AM Loetmichel: i have no spare rpi at hand at the moment, so i cant verify
08:54 AM JT-Cave: no 64 bit image
08:54 AM methods_: what model of pi?
08:54 AM Loetmichel: https://ubuntu.com/download/raspberry-pi
08:55 AM JT-Cave: 3 and 4
08:56 AM JT-Cave: hmmm https://ubuntu-mate.org/download/arm64/bionic/
08:57 AM methods_: i remember having some issues installing 64bit on mine
08:57 AM methods_: seems like some stuff wasn't working bluetooth or something can't remember
08:58 AM JT-Cave: I don't need bluetooth but I'll give them both a try
09:00 AM methods_: yeah i didn't need it either but just a warning
09:00 AM JT-Cave: ok thanks for the heads up
09:00 AM methods_: and it may not have been that either i'm just going from memory and that doesn't work as well as it used to
09:00 AM JT-Cave: here's your clue it don't get better...
09:01 AM methods_: i thought that might be the case
09:01 AM methods_: get to meet new people every day lol
09:01 AM JT-Cave: LOL yea
09:01 AM Centurion-Dan2 is now known as Centurion_Dan
09:05 AM JT-Cave: well I'm actually installing ubuntu 18 32 bit it seems
09:05 AM * JT-Cave wanders off to play with the chickens
09:32 AM perry_j1987: morning all
09:32 AM perry_j1987: everybody got their coffee?
09:32 AM JT-Cave: coffee already processed through the system
09:33 AM perry_j1987: already and coffee dont fit together in a sentence
09:34 AM perry_j1987: its a continuous involvement
09:35 AM Loetmichel: nice
09:36 AM JT-Cave: 3 cups and I'm done for the day
09:36 AM * Loetmichel walks in the kitchen, puts a mug under the Saeco machin *button press* *RUUUIIIIIIIII* *clackclack* *clackclack* *miiiieeerrrrk* *prrrrrrr* *prrrrrrrrrrrrrrrrrrrrrrrrrrr* *miiiiiiiifubb* ... adding caramel syrup, adding milk... *sip* "aahh, guuuuud!"
09:36 AM Loetmichel: :-)
09:36 AM JT-Cave: are you sure it sounds like that?
09:36 AM Loetmichel: JT-Cave_ i usuall have at least three POTs a day... habit from doing stage service for a decade ;)
09:36 AM Loetmichel: yes, pretty sure
09:37 AM perry_j1987: are those machine noises in your native tongue or translated to english machine noises
09:37 AM Loetmichel: kind of both
09:37 AM perry_j1987: lol
09:37 AM Loetmichel: i hope i hit the "translation" well
09:38 AM Loetmichel: its getting old an noisy.
09:39 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=12721&g2_imageViewsIndex=1 <- that one
09:40 AM perry_j1987: i just have a french press in use here
09:41 AM Loetmichel: its one of those fully automatic things that mill the beans then fill the permanent filter and then pump the boiling water at 15 bar thru the filter
09:41 AM Loetmichel: more like an espresso machine than a conventional french press/gravity filter
09:42 AM perry_j1987: i'd like one of those kind that come with a pretty barista girl
09:59 AM Loetmichel: JT-Cave: https://www.youtube.com/watch?v=rqTgpRtSIFU compare that to my omnotopia... i think i got it point on?
09:59 AM Loetmichel: not the milk part, just the coffee at the beginning
10:33 AM perry_j1987: https://www.youtube.com/watch?v=dwGt4STiJvM
10:33 AM perry_j1987: neat to see some small machines running nicely
10:35 AM gregcnc: he must have done those for essentially free
10:38 AM perry_j1987: what makes you say that
10:38 AM gregcnc: 4 days?
10:39 AM gregcnc: babysitting those parts
10:43 AM gregcnc: he does nice work with those little lathes
10:52 AM veegee: I'm getting inconsistent gas flow from my argon regulator at lower flow settings
10:52 AM veegee: like it's spitting sometimes, etc.
10:52 AM veegee: Does that mean I should get a dual stage regulator?
10:55 AM Loetmichel: or clean the regultor
10:56 AM Loetmichel: probably some crap inside
10:56 AM howto: guys is there a motor similar to the kress one but with a tool holder so you dont have to measure each time when you change the tool?
10:58 AM howto: yeah it seems that there is but the price is the same that i spent on my entire mill :)))
10:58 AM Loetmichel: howto: https://www.sorotec.de/shop/Fraesmotoren-neu/hf-spindel-aut-werkzeugwechsel/mechatron-spindeln/Hochfrequenzspindeln-397/
10:58 AM Loetmichel: but sit down before looking at the price ,)
10:59 AM howto: well i could search on second hand market maybe someone got tired of the hobby at some point
10:59 AM Loetmichel: https://www.sorotec.de/shop/Fraesmotoren-neu/hf-spindel-aut-werkzeugwechsel/mechatron-spindeln/vorsatzwechsler-fuer-rundspindeln/ <- maybe thats for you? it fits those chinese ER11/ER16 watercooled spindles
11:00 AM howto: i am seeing an amb one at 835 euros new
11:01 AM howto: it looks like the kress one i have only more automatic
11:01 AM perry_j1987: there are DIY ATC for er20 spindles
11:01 AM howto: but what am i saying...i havent even put the machine in working order and i am willing to spend more money into the oblivion? :))
11:01 AM perry_j1987: uses those alligator sockets mounted on a wheel and some gcode
11:02 AM Loetmichel: the latter link is for tol changed that can be mounted in front of a kress/watercooled china spindle
11:02 AM Loetmichel: those are NOT with a spindle motor, just the changer
11:03 AM howto: holy makerrel...the amb one has even a laser measuring port :))
11:04 AM Loetmichel: germans... you know? ;)
11:04 AM howto: Loetmichel...I allready have the current manual\ motor
11:05 AM howto: but if the price is right i am willing to buy the whole deal
11:05 AM Loetmichel: yeah, thats what i meant: the latter link is for a tool changer that mounts in front of an existing spindle
11:06 AM Loetmichel: IIRC all you need is the ER11/ER16 thread on the spindle and a 65/80mm diameter ring around the spindle to mount the changers body to
11:07 AM howto: i am tempted to just buy a license of the windows version of the milling software for the stepfour basic 540 and skip the whole linuxcnc mess...it seems too much hassle for this machine it seems
11:07 AM Loetmichel: if you arent able to mount the existing spindle a couple 100mm higher you lose some Z travel though
11:07 AM perry_j1987: you'll learn a lot going linuxcnc route
11:08 AM howto: perry_j1987 from who? someone needs to teach you for you to learn things
11:08 AM perry_j1987: there's a whole IRC channel here worth of people
11:09 AM howto: i am microns awya from milling my first workpiece and yet i am miles away from that
11:09 AM perry_j1987: and google's got a fairly big database of info too :)
11:09 AM howto: being a noob and using linuxcnc seem to be the worst combo of all
11:10 AM perry_j1987: i started with mach3 but quickly moved to linuxcnc
11:10 AM howto: but hey ...this year i managed to make the machine move all by itself :))
11:11 AM Loetmichel: howto: where are you located?
11:11 AM howto: perry with the mach 3, did you needed special low latency pc to run the mill or did you just connnect it and the machine just worked?
11:12 AM howto: Loetmichel europe
11:12 AM perry_j1987: back then my 6040 had a usb based controller card in it and it just ran off any old windows computer
11:12 AM Loetmichel: a BIT more precise? willing to drive a bit, but not 4 digits km
11:12 AM Loetmichel: <-offenbach am main, germany
11:12 AM howto: IchGucksLive seems to have left us from what i hear so....yeah i'm doomed here
11:12 AM perry_j1987: now i have a couple gae350n motherboards as the host controllers with parallel breakout boards for my machines
11:13 AM howto: yeah perry but you didnt needed some latency constraints that linuxcnc asks did you?
11:14 AM perry_j1987: just turned off things in bios i wasnt using
11:14 AM perry_j1987: and ran the debian wheezy version of linuxcnc
11:15 AM howto: if i would have ran something else on mine the latency test would have been in seconds range
11:15 AM howto: with this one i have 200.000 nanoseconds
11:16 AM howto: i cannot compile smictrl on wheezy i have the libpci-dev installed finally
11:16 AM howto: that might shave off some orders of magnitude
11:17 AM howto: from the 6 digit nanoseconds i get
11:18 AM howto: so as you saw Loetmichel it would be one long ride to my place
11:18 AM perry_j1987: what is smictrl
11:19 AM howto: but IchGucksLive broght me the closest to working with the machine as i will probably ever get with the stepfour basic 540 on linuxcnc...although it took me allmost two years to get here
11:20 AM howto: did anybody made any latency test on a lenovo t400 that can share the results with us?
11:21 AM howto: i asked someone today to search for one so i can do the test but who knows if one will show up
11:22 AM howto: perry smictrl is a piece of software that you compile and run on the pc that will be used on the cnc with the distro that will run linuxcnc
11:24 AM howto: after compile and run the said software the latency of the system hopefullt will be brought in the realm of usability with the linuxcnc program and RTAI task 1 won't complain about being late again
11:24 AM perry_j1987: ah
11:24 AM gregcnc: is it still applicable to newer PC?
11:25 AM howto: i suppose so...proably...i dont know
11:25 AM howto: every computer with dramatic latency issues like mine i guess
11:25 AM howto: to\
11:27 AM howto: i cannot compile it on the distro itself.On the ubuntu compiles fine but it is no use...it needs to be compiled on the distro itself from what i hear
11:27 AM howto: the errors are as follows:
11:27 AM howto: cc: error: unrecognized command line option ‘-r/source/include’
11:28 AM howto: cc: error: lpci: No such file or directory
11:28 AM howto: these are the errors
11:28 AM howto: on ubuntu works fine
11:28 AM veegee: is gcc actually gcc?'
11:28 AM veegee: or is it clang/llvm or something else in disguise?
11:29 AM veegee: also verify that `libpci.so` exists somewhere and it is in your LDPATH
11:29 AM howto: i dont have any idea...all i know it compiles fine on ubunutu 18.04 and on tthe wheezy it doesnt
11:29 AM veegee: `sudo find / -type f -iname '*libpci.so*'
11:30 AM veegee: run the command above, ignore the backtick character at the front, that's a typo
11:30 AM howto: i suspect libpci.so installs with libpci-dev veegee does it not?
11:30 AM veegee: apt-file search libpci.so
11:31 AM veegee: maybe not with the -dev package, but yeah one of the packages. The command above will tell you what package
11:31 AM veegee: You may have to install apt-file first
11:31 AM howto: ooh and i have gone through literal hell convincing wheezy to install libraries since its EOL now
11:33 AM howto: it literarly refused anything regarding installs
11:33 AM howto: yeah its there
11:33 AM howto: i just searched it from ubuntu on the harddrive partition...this was the easiest thing i managed to do today without going to hell and back for it :)))
11:34 AM howto: do you what the path for it too?
11:36 AM howto: the path is usr/lib/i386-linux-gnu
11:38 AM howto: there is a libpci.so.3 and a libpci.so.3.1.9 these both have the path lib/i386-linux-gnu
11:38 AM howto: beside the one i mentioned...maybe this is a problem
11:39 AM howto: i just wanted to see if the smictrl would have improved things not that i expect wonders from it...the numbers are way too high for that kind of miracle :)))
11:41 AM howto: if by any chance i am in that mircale range i will make an extensive tutorial abou it so no one else would have to go through the same ordeal i'gone
11:41 AM howto: miracle/
12:01 PM roycroft: hey folks
12:01 PM roycroft: this is for anyone who does 3d printing
12:02 PM roycroft: would a fine scotch-brite 6"/150mm grinder deburring wheel be too aggressive for smoothing the edges on parts printed with pla?
12:03 PM roycroft: i'm talking about straight edges with small fillets
12:03 PM SpeedEvil: I suspect so.
12:03 PM roycroft: not sculpted pieces
12:03 PM roycroft: i thought maybe so as well
12:03 PM SpeedEvil: Though if you could reduce the RPM a lot
12:03 PM roycroft: that i can't really do
12:03 PM roycroft: i could get a scotch-brite belt for my 2x72 grinder, remove the platen to put it in slack mode, and slow that down
12:04 PM roycroft: the 2x72 has a 3 phase motor
12:04 PM roycroft: my bench grinders do not
12:04 PM SpeedEvil: You could pop it on an improvised arbor and hook it up to a drill at slow speed
12:04 PM roycroft: regardless, a very light touch would be needed
12:04 PM roycroft: i could, i suppose
12:05 PM roycroft: but also, a 6' scotch brite deburring wheel is $65
12:05 PM roycroft: and i can get a 2x72 scotch brite belt for about $25
12:07 PM roycroft: 6", rather
12:07 PM roycroft: but i'm sure you understood
12:07 PM roycroft: folks talk about carefully wet sanding parts, but i'm going to be printing a lot of them, and there will be just one small section that needs a bit of post-processing
12:07 PM SpeedEvil: Are the big floor machines 2'?
12:08 PM roycroft: i don't want to waste a lot of time doing it by hand
12:08 PM SpeedEvil: Have you considered resin printers?
12:08 PM roycroft: the parts are little boxes with a fillet around the bottom
12:08 PM roycroft: i looked at resin printers
12:08 PM roycroft: the resin is too expensive
12:08 PM roycroft: and i don't need that kind of quality
12:09 PM roycroft: i just need to get rid of some slightly rough edges
12:09 PM SpeedEvil: Have you also ensured you can't tune your printer batter?
12:09 PM roycroft: i've done some fine tuning
12:09 PM roycroft: but a fillet on the bottom of a part means printing overhangs
12:10 PM roycroft: either i add supports, which need to be cleaned up after removal, or know that the overhang is going to be a little wonky, and needs a bit of cleanup
12:10 PM roycroft: it's not a big deal
12:10 PM roycroft: it will probably take like 5 seconds per part to clean up if i do it with a powered scotch brite pad of some sort
12:11 PM roycroft: but it might take a minute or two per part if i wet sand by hand
12:11 PM roycroft: i like 5 seconds better
12:11 PM SpeedEvil: Also, dipping in something may work
12:11 PM roycroft: pla isn't very soluble
12:11 PM roycroft: ethyl acetate is the primary solvent that works with it
12:11 PM perry_j1987: pla likes to melt with sanding friction
12:11 PM SpeedEvil: - for example some have been dipping in resin printer stuff and just using it as a topcoat and then UV exposing
12:11 PM roycroft: and that's expensive
12:12 PM roycroft: hence the light touch, perry_j1987
12:12 PM perry_j1987: what are you printing
12:12 PM roycroft: i think i'll get a 2x72 scotch brite belt and give it a go
12:12 PM roycroft: i have been planning on getting one anyway for other uses
12:12 PM roycroft: hardware storage boxes
12:12 PM roycroft: so shop quality is all i need
12:13 PM roycroft: i don't need them to look pretty
12:13 PM perry_j1987: why sand at all
12:13 PM roycroft: i just need them to be smooth
12:13 PM SpeedEvil: what dimensions?
12:13 PM roycroft: and there's just the one part
12:13 PM perry_j1987: are you doing that drawer organizer thing
12:13 PM roycroft: 45x45 square
12:13 PM perry_j1987: the grid of boxes
12:13 PM roycroft: sort of
12:13 PM roycroft: i'm doing my own thing, but yes, drawers full of boxes
12:14 PM perry_j1987: https://www.youtube.com/watch?v=CHFK5sY8ToE
12:14 PM roycroft: and i'd rather not print them all myself
12:14 PM roycroft: but i spent months searching for a vendor of pre-made boxes that were affordable and available in multiple sizes that would mesh well
12:14 PM perry_j1987: takes a long time to print
12:14 PM roycroft: i found one vendor, but each size was not an exact multiple of the base size
12:15 PM perry_j1987: perfect solution to 3d printing a master and making a silicone mold to urethane cast
12:15 PM roycroft: so with an n x n base size, 2n x n would be a little less than 2n wide
12:15 PM roycroft: yes, making molds has been suggested
12:15 PM roycroft: i don't want to go there
12:16 PM roycroft: i'm not going to build the drawer units until autumn, at least
12:16 PM SpeedEvil: CNC router -> sheet of ply
12:16 PM roycroft: so even though it will take a long time to print, i have a lot of time
12:16 PM roycroft: and i work from home full time now, so i can run over to the printer to pull off a part every hour
12:16 PM roycroft: and get several/day done
12:17 PM perry_j1987: casting is a ton of fun though
12:18 PM SpeedEvil: Also, polycarbonate sheet is about the same price as PLA
12:18 PM SpeedEvil: https://www.cabp.co.uk/Solid-Sheets/Polycarbonate-Sheets/3mm-Solid-Polycarbonate-Sheet-Clear/3mm-2440-x-1220-Solid-Polycarbonate-Sheet-CLEAR_FC32412CL.htm
12:19 PM perry_j1987: so fixture design, why do i see a lot of fixtures that include op 1 and op 2 on same fixture
12:20 PM perry_j1987: instead of just all op 1 etc
12:25 PM W1N9Zr0: if you have common tools between ops, it would save you some tool changes
12:30 PM perry_j1987: i just got some miteebite uniforce clamps the other day and need to design my first fixture lol
12:31 PM perry_j1987: bought a pack so got 6 clamps will be able to do 12 parts
12:34 PM roycroft: i might just try a P220 belt, which i have in stock, to see how that goes
12:34 PM roycroft: using materials on-hand is even cheaper than $25
12:38 PM roycroft: maybe P180 would be better
12:38 PM roycroft: i want the part to be smooth, but the finer the grit the hotter it gets
12:38 PM roycroft: P120 might even be ok for this
01:00 PM perry_j1987: https://www.youtube.com/watch?v=In6VqiHL7rM
01:28 PM JT-Cave: well ubuntu 18 mate sucks but the gpio works, debian the gpio doesn't work :( raspberry pi os qstreamer does not work
01:29 PM Jymmm: LOL mate 18 sucks?
01:29 PM Tom_L: ubuntu on the rpi?
01:29 PM JT-Cave: yea it overrides all my qss styles in pyqt5
01:29 PM JT-Cave: so we all must conform or be assimilated
01:30 PM Tom_L: JT-Cave, did you take your surplus stuff off your store?
01:30 PM Tom_L: or is it all gone
01:30 PM JT-Cave: never added it to the new store, what do you need?
01:30 PM Tom_L: nothing but i was looking for those relays
01:31 PM JT-Cave: 24v control relays?
01:31 PM Tom_L: yes
01:31 PM JT-Cave: I don't have any more of them
01:31 PM Tom_L: :(
01:31 PM Tom_L: i still have a spare or so
01:31 PM Jymmm: Tom_L: How many do you need and what specs?
01:32 PM Tom_L: i don't _need_ any
01:32 PM Jymmm: s/need/desire/
01:32 PM Tom_L: i was just looking on his site and didn't see em
01:33 PM Tom_L: Jymmm, you think that switch you posted yesterday is any good?
01:33 PM Tom_L: mains switch
01:34 PM Jymmm: Tom_L: The ATS? IT's rated at 100A, but he said in the video that he doesn't think it's 100A when he took it apart in the video
01:35 PM Jymmm: I still think he's using it though
01:35 PM Jymmm: he did put it on the scope in the video
01:36 PM Jymmm: Tom_L: In another video he made one from individual contactors, looked cool
01:41 PM Tom_L: hmm
01:45 PM Tom_L: being under rated is standard procedure for china
02:13 PM unterhaus_: link to mains switch?
02:14 PM unterhaus_: I got some of the sonof switches today, but I might use one to drive a real relay and not whatever that thing is on the device
02:15 PM unterhaus_: I'm not sure how many amps the coil on my contactor pulls, sonof might be able to drive it okay
02:41 PM perry_j1987: hmm should i bother with designing a whole subplate and locating pins for my first fixture
02:41 PM perry_j1987: or just make a small one to go in the machine vise to get started... decisions decisions
02:45 PM unterhaus_: what are you fixturing?
02:49 PM unterhaus_: tasmota looks really cool, but it's like linuxcnc in that it's infinitely configurable
02:49 PM unterhaus_: I am not sure I want to dive down yet another rabbit hole
02:50 PM perry_j1987: i want to make one fixture that can hold barstock and i can slot it to size, to individual blanks
02:50 PM perry_j1987: then take the blanks out and hold the blanks for machinging in the vertical position
02:51 PM perry_j1987: i think i can do the fixture with a set of pockets next to each clamp that will give me registration faces for the individual parts, and a shelf on top for holding the full bar stock lengths
03:15 PM andypugh: multifix
03:15 PM andypugh: Doh! That was meanf for the search bar
03:23 PM perry_j1987: hmm trying to figure out a solution to make these registration faces
03:24 PM perry_j1987: im trying to make a fixture that can slot long bar stocks to length and then flip up the individual pieces cut against registration faces to mill
03:25 PM gregcnc: wouldn't sawing be faster?
03:25 PM jymmmm: 500mKW
03:27 PM jymmmm: So how many watts is that?
03:27 PM gregcnc: millikilowatts?
03:27 PM jymmmm: yep
03:27 PM jymmmm: gregcnc: 500 of them
03:28 PM gregcnc: covers all the options? can't be wrong?
03:28 PM perry_j1987: sawing requires you to saw it and then put it on the mill individually and face them and then face other side to length
03:28 PM perry_j1987: thats what i've been doing all this time but it sucks lol
03:29 PM andypugh: 369 ft.lbs/sec
03:29 PM CaptHindsight: howmany HP is that?
03:29 PM andypugh: A 2/3hp
03:30 PM CaptHindsight: we should just call em Uhmerican Units and be done with it
03:30 PM perry_j1987: so if i slot em out in the fixture it gives me an op tht i dont have to manage
03:30 PM CaptHindsight: Metric vs uhmerican
03:31 PM perry_j1987: when i walk back to the machine i'll have 12 of them cut to size, faced and ready for machining
03:31 PM jymmmm: CaptHindsight: Show us your metric watch!!!
03:31 PM andypugh: perry_j1987: How long? Much longer than a vice?
03:31 PM Tom_L: parallel vises
03:31 PM CaptHindsight: jymmmm: mine be binary
03:31 PM perry_j1987: i've been cutting them in bandsaw and then side milling them out the side of my vise for long time
03:31 PM gregcnc: go to miteebite and get some ideas
03:31 PM jymmmm: CaptHindsight: metric binary
03:32 PM perry_j1987: i have a set of uniforce clamps from miteebite
03:32 PM andypugh: Jymmm: https://en.wikipedia.org/wiki/Decimal_time
03:32 PM perry_j1987: im trying to design a fixture that is dual purpose right now
03:32 PM gregcnc: what kind of bar is this?
03:33 PM gregcnc: fun using telepathy to guess design requirements
03:33 PM jymmmm: andypugh: I kinda like this https://upload.wikimedia.org/wikipedia/commons/b/bf/Decimal_Time_Clock.jpeg
03:33 PM jymmmm: BRB, reboot post update
03:33 PM Tom_L: gregcnc, :)
03:34 PM perry_j1987: just some alum or brass bars
03:35 PM Tom_L: round, hex, square, rectangle?
03:35 PM CaptHindsight: how flat do the ends of the bar have to be?
03:35 PM perry_j1987: square or rectangle
03:35 PM perry_j1987: milled flat
03:36 PM perry_j1987: bandsaw leaves too rough finish etc.
03:36 PM gregcnc: bar fed twin spindle twin turret lathe or maybe a willemin
03:37 PM gregcnc: or do as all the kool people are now and buy a Kern or 2
03:37 PM roycroft: my bandsaw typically leaves a finish that can be cleaned up in a few seconds with a file or a touch to the belt grinder, for parts whose dimensions are not critical
03:38 PM perry_j1987: they have to be milled to length
03:38 PM gregcnc: that's my suggestion based on I guessed the part is and tolerances are
03:39 PM Tom_L: how long are the bars?
03:39 PM CaptHindsight: how thick are these bars?
03:39 PM roycroft: if they are longer than your mill vise then clamp a block of steel or aluminium onto the mill table at approximately the correct length and index off of that
03:40 PM CaptHindsight: I use a non-ferrous blade on a circular mitre saw
03:40 PM CaptHindsight: for cutting t-slot
03:41 PM perry_j1987: eventually i plan to do the whole subplate and dowel in bushing locating fixtures on the t-slot
03:41 PM perry_j1987: right now just wanting to play with these clamps and make my first simple fixture
03:42 PM perry_j1987: so i can start playing with cam patterning and such
03:43 PM gregcnc: there are a lot of practical ideas out there. without seeing the part, it's simply not possible give a good answer
03:43 PM roycroft: but that sure won't stop us from giving random answers, will it?
03:43 PM roycroft: :)
03:43 PM gregcnc: google can turn up all sorts of stuff
03:44 PM perry_j1987: i was just looking for ideas for stops features to add to the model
03:45 PM gregcnc: all depends on the part and the step you take to make it
03:45 PM gregcnc: steps
03:46 PM Tom_L: i generally make them up as i go
03:46 PM gregcnc: I plan during the design stage
03:46 PM Tom_L: well yeah per job
03:48 PM perry_j1987: maybe i could just put in some pins
03:50 PM gregcnc: if machining is light, pins may work
03:50 PM perry_j1987: ya i got a bunch of 3mm dowel pins sitting here
03:51 PM perry_j1987: ya this part of the processes is just some drilling ops
03:51 PM CaptHindsight: I usually only do a few myself, si it doesn't matter much
03:51 PM Tom_L: make sure the clamp is across from the pin or the bar may warp under tension
03:52 PM CaptHindsight: shop down the street turns bar into tools for Snap-On, so they can handle volume
03:52 PM perry_j1987: the clamp is 90 degree from where the pin is
03:52 PM perry_j1987: the pin is just the stop for the individual pieces to locate
03:52 PM perry_j1987: the clamp pushes the work into the side of the fixture and also the vise jaws
03:52 PM gregcnc: oh that's very common
03:53 PM CaptHindsight: gregcnc: have you noticed that most shops around here do mostly swiss turning
03:53 PM perry_j1987: so for installing the pins
03:53 PM Tom_L: too bad you don't have a tool changer. we used to use a dowel as a tool with zero rpm and bring it down to locate the material in a vise etc
03:53 PM perry_j1987: am i going to need a special reamer to make the holes just right to press them in or should i be able to do it fine iwth drill bits?
03:53 PM gregcnc: I have noticed there are quite a few. it makes money
03:54 PM Tom_L: i ream all dowel pins
03:54 PM perry_j1987: what size reamer if its 3mm dowel pin
03:54 PM gregcnc: good luck with drills, unless name brand carbide
03:54 PM Tom_L: 3mm
03:54 PM perry_j1987: i imagine its some fraction smaller than 3?
03:54 PM CaptHindsight: a shop in Spring Grove has ~40 swiss machines
03:54 PM roycroft: twist drills do not drill round holes, nor do they drill consistent size holes
03:54 PM gregcnc: swiss automation in barrington is huge
03:55 PM CaptHindsight: heard of them
03:55 PM Tom_L: roycroft, stop using square drills :)
03:55 PM gregcnc: over 100 swiss iirc
03:55 PM perry_j1987: wow
03:55 PM CaptHindsight: gregcnc: yeah off 14
03:56 PM roycroft: twist drills are the recprocating saws of hole making devices
03:56 PM gregcnc: they also quoted the highest price ona small batch of parts i quoted years ago
03:56 PM CaptHindsight: gregcnc: was looking at space near them
03:56 PM Deejay: gn8
03:57 PM CaptHindsight: gregcnc: http://www.alpha-swiss.com
03:57 PM gregcnc: roycroft, you may want to look at some catalogs for carbide drills
03:57 PM CaptHindsight: next to the Waterjet place
03:58 PM gregcnc: swiss are expensive but profitable if you can run them efficiently
03:59 PM gregcnc: does that company you mentioned only make parts for snapon or all the labels?
04:00 PM CaptHindsight: snap-on is a big customer but they do just about anything on the smaller side <3" dia
04:01 PM pink_vampire: hi
04:01 PM gregcnc: i have random ratchets and extensions with all the names, but come from the same factory
04:02 PM perry_j1987: i'd be interested in a tiny benchtop swiss style lathe
04:02 PM perry_j1987: i was googling around but didnt see anyone doing that in a cursory glance
04:02 PM gregcnc: Citizen R04
04:02 PM gregcnc: as close as you're going to get
04:04 PM perry_j1987: all of us around southern wi / northern ill should get together and colelct some fun machines
04:04 PM * jymmmm is back biotches! No whining now, you were warned :D
04:05 PM CaptHindsight: there are 2 working Matsuura 500's on ebay for $1100 or best ea
04:05 PM jymmmm: are they still doing the ohio fest or whatever it's called?
04:05 PM CaptHindsight: near Chicago
04:05 PM CaptHindsight: jymmmm: there is a fest in Michigan
04:06 PM gregcnc: the one all the yt machinist show up at?
04:06 PM jymmmm: gregcnc: I think so
04:06 PM jymmmm: CaptHindsight: is that the big one?
04:07 PM CaptHindsight: it was www.cnc-workshop.com
04:08 PM jymmmm: CaptHindsight: BUY THIS DOMIN
04:08 PM jymmmm: DOMAIN
04:10 PM gregcnc: perry_j1987 here are a few https://chicago.craigslist.org/nwc/bfs/d/crystal-lake-okuma-genos-cnc-mill/7142338296.html
04:11 PM perry_j1987: i need deeper pockets
04:12 PM gregcnc: then you definitely need a https://www.kickstarter.com/projects/1260359869/swissmak-the-mill-turn-center-for-your-machine-sho/description
04:12 PM jymmmm: So, what do you say/do to this very proud little girl??? https://i.imgur.com/oUFSw4B.jpg
04:12 PM CaptHindsight: https://www.ebay.com/itm/1981-MATSUURA-MC-500V-CNC-with-YASNAC-3000G-control/283531831618 has 2 of them
04:12 PM gregcnc: https://www.kickstarter.com/projects/1260359869/swissmak-the-mill-turn-center-for-your-machine-sho/description
04:12 PM gregcnc: oops https://www.practicalmachinist.com/vb/cnc-machining/swissmak-anyone-know-what-happened-355434/
04:13 PM jymmmm: perry_j1987: make a cnc sewing machine to deepen them
04:13 PM perry_j1987: lol
04:14 PM perry_j1987: ok think im getting somewhere with this fixture
04:14 PM CaptHindsight: he that Swiss machine made from aluminum and hard anodized ways
04:14 PM perry_j1987: the barstock could rest on the tops of the pins for slotting
04:15 PM perry_j1987: think the barstock can be supported just between the face of the uniforce clamp and the side of the fixture for slotting
04:17 PM CaptHindsight: perry_j1987: the point that people were trying to make is that to provide intelligent answers it requires a full set of specs
04:17 PM CaptHindsight: piecemeal info only works for jymmmm since we love him :)
04:18 PM perry_j1987: that is the whole info though lol
04:18 PM jymmmm: CaptHindsight: piecemeal?
04:18 PM perry_j1987: barstock held with uniforce clamps sitting ontop of locating pins for a slotting op
04:18 PM jymmmm: (I'm lost in the conversation atm)
04:18 PM perry_j1987: then once slotted the clamps released and the individual parts put into the clamps against the locating pins
04:25 PM Tom_L: jymmmm, sure you're just not lost .
04:26 PM jymmmm: Tom_L: WEll, I LIKE being lost, I find the most AMAZING things
04:26 PM Tom_L: jymmmm, was that your daughter?
04:26 PM jymmmm: Tom_L: No just found the pic
04:26 PM Tom_L: i wouldn't admit it either
04:27 PM jymmmm: Tom_L: But what do you say to her? Do you get your car repaired? Squash her "creativity"? lol
04:28 PM Tom_L: depends if it's the bentley or the vw
04:28 PM jymmmm: Oh you know it'll be the Bentley
04:29 PM jymmmm: I say fuck it, keep it and get it clear coated. BONUS is you could embarass her in her later years =)
04:32 PM CaptHindsight: that will buff right out
04:32 PM jymmmm: CaptHindsight: and break her heart? She looks so proud of her work =)
04:32 PM gregcnc: fake pic for clicks, there are several versions
04:33 PM gregcnc: meme
04:33 PM jymmmm: gregcnc: fake or not, it's all the same
04:33 PM gregcnc: same as what
04:33 PM CaptHindsight: what if you daughter does it at 30?
04:34 PM jymmmm: CaptHindsight: haha, IDK
04:34 PM jymmmm: gregcnc: If your daughter did that, what would you say/do?
04:36 PM gregcnc: what can you do? if it was a really nice car, I may be upset. My car's aren't worth much more than the tires on them
04:36 PM andypugh: perry_j1987: I have deep pockets, and short arms.
04:36 PM perry_j1987: sounds like you accumulate wealth and dont spend it heh
04:37 PM perry_j1987: naturally predisposed eh? :P
04:37 PM Tom_L: perry_j1987, just wave a lathe in front of him if you wanna see him reach...
04:37 PM gregcnc: wife was just reading a post on fb. neighbors are pissed because 4yo daughter was throwing rocks at the neighbors window with the neighbor boy. results broken 1500USD window who pays?
04:37 PM CaptHindsight: live within your memes
04:37 PM roycroft: the parents of the rock thrower
04:38 PM andypugh: gregcnc: The kids pay. No food until it’s covered.
04:38 PM roycroft: why is this even being discussed by anyone?
04:38 PM gregcnc: because facebook, duh
04:38 PM CaptHindsight: because at 4 they don't have the reasoning
04:38 PM Tom_L: i say take it to court and figure out who dared whom
04:38 PM roycroft: i've never stooped so low as to go there, actually
04:38 PM roycroft: i have heard about it
04:38 PM CaptHindsight: and they were both doing it
04:38 PM roycroft: that's irrelevant, tom_l
04:39 PM andypugh: And: $1500 for a window?
04:39 PM roycroft: a 4-year-old is not capable of being responsible
04:39 PM CaptHindsight: the parents should pay
04:39 PM roycroft: it's the parents who are not properly supervising their child
04:39 PM Tom_L: if i paid $1500 for a window and it broke that easy i'd be lookin for a refund
04:39 PM CaptHindsight: how large a rock can a 4 year old throw?
04:39 PM gregcnc: it was a high impact window, not sure what that means, but i'd glass like windshiled glass
04:40 PM gregcnc: brain doesn't connect to fingers. guess like windshield
04:40 PM CaptHindsight: what if your child breaks something at your ex's house while visiting?
04:40 PM perry_j1987: must have been one of them tesla truck windows
04:40 PM Tom_L: heh
04:41 PM CaptHindsight: do you reward them?
04:41 PM andypugh: gregcnc: No, actually, it clearly _wasn’t_ a high impact window, it was broken by a 4-year old
04:41 PM gregcnc: windows aren't cheap, unless you still have single pane
04:41 PM roycroft: capthindsight: the ex is the "active" parent at that time
04:41 PM gregcnc: glass is tricky like that, one shapr point and it crumbles
04:42 PM CaptHindsight: roycroft: see question #2^^
04:42 PM roycroft: now if the stipulation was supervised visition, whoever is supervising is the responsible one
04:42 PM andypugh: I the UK you can double glaze an entire house for £1500 including frames and fitting. Replacement glass shouldn’t be nearly that much.
04:43 PM CaptHindsight: ok forget window say it was a $1500 bottle of wine
04:43 PM andypugh: If they own a £1500 bottle of wine they can afford to replace their own damned window :-)
04:43 PM roycroft: let's stick to the window
04:44 PM roycroft: if the window were defective, the parents of the child who broke the window should pay for it, and they would then have cause to try to collect from the window manufacturer
04:44 PM CaptHindsight: maybe it's a good lesson.....
04:44 PM roycroft: or they could claim that they should not be responsible because the window was defective
04:44 PM CaptHindsight: maybe there should not be an expensive window there
04:45 PM andypugh: TBH I would rather expect this to be covered by home insurance.
04:45 PM CaptHindsight: replace with plywood, lesson learned
04:45 PM roycroft: and attempt to legally force the window owner to try to collect from the manufacturer first
04:45 PM roycroft: and then be responsbile for anything the manufacturer does not pay
04:45 PM CaptHindsight: home insurance with $1500 deductible
04:45 PM roycroft: including labor to replace it
04:46 PM roycroft: but i'll repeat
04:46 PM andypugh: Aye, if a “high impact” window is broken by a 4 year old it was probably _dangerous_ sue the manufactuere, the child could have been taumatised.
04:46 PM roycroft: a 4-year-old child should not be in a situation to be throwing rocks at windows
04:46 PM roycroft: and is incapable of understanding the implications of doing so
04:46 PM gregcnc: but this is the world we live in, nobody said my house I replace it. or my kid i replace it.
04:46 PM roycroft: therefore the parents are negligent for permitting the situation in the first place
04:47 PM CaptHindsight: we really don't know the full circumstances
04:47 PM roycroft: true
04:47 PM CaptHindsight: maybe a terrorist framed the small child
04:48 PM CaptHindsight: some anti-child group
04:48 PM CaptHindsight: don't admit to anything blame it on fake news
04:49 PM roycroft: and if the 4-year-old were visiting at the house where the window was broken, and the homeowner was acting in loco parentis, then the parents might not be responsible
04:49 PM roycroft: but the actual parents must have a clear understanding that the homeowner is taking on responsiblity for supervising the child
04:50 PM perry_j1987: i should be fine with fixture sticking out 1 inch off each end of the machine vise eh?
04:50 PM gregcnc: is the vise a 1" or 12"
04:50 PM perry_j1987: 1" thick fixture
04:50 PM perry_j1987: its 3" machine vise
04:51 PM gregcnc: probably
04:51 PM perry_j1987: its only used for drilling ops
04:51 PM perry_j1987: and the slotting
04:52 PM roycroft: actually doing plunge cuts is not very good for unsupported workpieces
04:52 PM perry_j1987: using 1/8in endmill to for slotting them out to keep the size of the fixture down
04:52 PM roycroft: if you're really concerned about accuracy then put a machinst's jack underneath the overhanging ends
04:52 PM gregcnc: right
04:52 PM perry_j1987: roycroft this is on a 6040 router so i dont have much z rigidity and run it pretty soft
04:53 PM roycroft: it might flex by a thousandth or two otherwise
04:53 PM perry_j1987: this 1" alum fixture is stronger than the whole z axis
04:53 PM roycroft: well try it without and see how it goes
04:53 PM roycroft: if you don't like the results, i just told you a way to make it more accurate
04:53 PM perry_j1987: aye
04:53 PM roycroft: and you can try again
04:54 PM perry_j1987: there'd be room to drill and tap holes underneath to have built in jacks if needed
04:55 PM roycroft: i think you need to watch some abom79 videos, perry_j1987
04:55 PM roycroft: he likes to be dead nuts on every time, and shows how he does it
04:55 PM andypugh: perry_j1987: N ot sure this helps, but this is a fixture I am making to machine two different chiralaties of a patricular part. https://a360.co/35JAhmY
04:55 PM perry_j1987: all thats out the window though if your machine is a wet noodle haha
04:55 PM roycroft: i think he gets carried away at times
04:56 PM perry_j1987: part of his brand :P
04:56 PM roycroft: yes
04:57 PM perry_j1987: andypugh what does that go into
04:57 PM andypugh: The main body bolts down into the T slots of the mill table.
04:58 PM roycroft: and based on all the toys he's able to buy, and the amount of time he must have to spend on production of his youtube videos every week, i have to assume that his brand works really well for him, as he can't spend more than 20 hours/week on actual machining jobs
04:58 PM andypugh: Then the blanks are clamped in to the slot for the first op, then flat down on the top (edge clamping plate not shown) for the second op.
04:58 PM gregcnc: does he still have a day job?
04:58 PM roycroft: he quit his job at the machine shop where he used to work
04:59 PM roycroft: but i think he still does some machining jobs at his own shop that are not part of his videos
04:59 PM gregcnc: i'm still subsribed but haven't watched much in several years. 98% shaper videos now it seems?
04:59 PM roycroft: but he spends so much time on the road and buying/installing/fixing machines he can't have much time for that
04:59 PM roycroft: he has two shapers now :)
04:59 PM andypugh: A man who is tired of shaper videos is tired of life!
05:00 PM Tom_L: says the guy with no shaper
05:00 PM roycroft: but he just did a shaper job on the k&t mill, and the while time kept saying he should hav done it on the shaper
05:00 PM andypugh: (The Fireball Tools shaper is a gorgeus thing, with the built-in compound table)
05:00 PM gregcnc: half teh video is watching the return stroke
05:00 PM roycroft: i thought andypugh had a shaper in the loo
05:01 PM andypugh: Ah…… Not quite _half_. Shapers have a fast retract as a cunning part of the design.
05:01 PM gregcnc: sorry 1/3rd
05:02 PM syyl: cant watch shaper videos anymore
05:02 PM syyl: i am over it :D
05:02 PM gregcnc: I just watched something about toolposts today ;)
05:02 PM syyl: probably boring as hell
05:03 PM syyl: 0/10 would not watch
05:03 PM gregcnc: i did like the vee block
05:04 PM gregcnc: i have so many podcasts to catch up on and there are more and more new ones
05:05 PM syyl: i can highly recommend this one
05:05 PM syyl: https://rss.com/podcasts/microcast/
05:05 PM syyl: they actually know what they talk
05:06 PM roycroft: abom was saying the other day that shapers can make parts that are flatter than can be done on a milling machine, because the scraping action does not heat up the part like a rotary cutting tool does
05:07 PM syyl: yeah..no
05:07 PM roycroft: and that for really accurate parts you still need to surface grind and scrape them, but often times you can make things good enough on a shaper that aren't good enough on the mill
05:07 PM roycroft: i'd like to see some empirical data on that
05:07 PM syyl: you wont
05:07 PM syyl: :D
05:07 PM roycroft: it's one of those things that sounds plausible
05:08 PM roycroft: but can't be believed until the data prove it
05:08 PM syyl: surfacegrinding is not inherent more precise than milling
05:08 PM syyl: nor is planing more precise than milling
05:08 PM syyl: it comes more down to machine design
05:08 PM roycroft: if you can keep the part cool enough it seems to me that it can be millled pretty accurately
05:09 PM syyl: i bet that a sip hauser bridge-jigborer will flycut flatter than any shaper.
05:09 PM syyl: because the machine is designed to do exactly that
05:09 PM syyl: a bridgeport with its only in the middle supported table, not so much
05:10 PM roycroft: but adam (two shapers) booth needs to justify his addiction ...
05:10 PM roycroft: so believe him
05:10 PM syyl: which is totaly fine
05:10 PM roycroft: at least don't let his wife know you don't believe him
05:11 PM syyl: :D
05:12 PM * roycroft is sad that nobody got the reference to arthur (two sheds) jackson
05:12 PM syyl: :(
05:13 PM roycroft: well, it's officially the weekend
05:14 PM roycroft: and my drum sander is almost fully reassembled
05:14 PM roycroft: i might actually get that working tonight
05:20 PM pink_vampire: roycroft: G1 Z0 G1 Z50
05:20 PM pink_vampire: this is my drum sender
05:21 PM pink_vampire: BTW, is there a way to make loop in gcode in linuxcnc?
05:22 PM perry_j1987: just copy paste it how many times you want it to loop?
05:25 PM andypugh: roycroft: I got it, but didn’t think to comment. It’s just part of culture now. Like the MP John “two jags” Prescott. https://en.wikipedia.org/wiki/John_Prescott
05:25 PM andypugh: pink_vampire: Yes. Many types of loops are supported
05:26 PM pink_vampire: andypugh: COOL!
05:26 PM andypugh: http://linuxcnc.org/docs/2.7/html/gcode/o-code.html#ocode:looping
05:28 PM andypugh: pink_vampire: This is a slightly extreme example of what you can do in hand-coded G-code with loops and data tables: https://bodgesoc.blogspot.com/2016/11/cams.html
05:28 PM perry_j1987: https://i.ibb.co/nzNhcsG/Screen-Shot-2020-06-26-at-5-18-04-PM.png
05:28 PM perry_j1987: here we go
05:28 PM perry_j1987: thats what i got so far
05:31 PM perry_j1987: https://i.ibb.co/dfhfLXY/Screen-Shot-2020-06-26-at-5-21-33-PM.png
05:31 PM perry_j1987: so other side of the uniforce clamps is reversed so it references off the same contact points for all 12 parts
05:33 PM pink_vampire: andypugh: is there a way to make infinite loop until the probe hit something?
05:42 PM andypugh: Yes, but be careful.
05:43 PM andypugh: The graphical preview can get stuck with an actual infinite loop.
05:43 PM andypugh: You can program O100 WHILE [1] and that will run for ever
05:46 PM andypugh: So you might need to use O100 WHILE [#<_task>] dor your loop. See http://linuxcnc.org/docs/2.7/html/gcode/overview.html#sub:system-parameters for why….
05:46 PM XXCoder: pink making a probing script?
05:47 PM pink_vampire: XXCoder: almost
05:47 PM pink_vampire: I want to make better CNC driven drum sander
05:48 PM pink_vampire: so I need something that will move the Z up and down.
05:49 PM pink_vampire: right now I just have a file with about 100K line, with Z up Z down and I run this code and just hit stop when I finish sanding.
05:49 PM pink_vampire: it work fine, but I was thinking maybe there is better way.
05:49 PM XXCoder: cool :)
05:50 PM andypugh: pink_vampire: Yes, you want an infinite loop for that.
05:50 PM andypugh: Then is can be a 4 line program.
05:51 PM andypugh: Or, do it in HAL and have no g-code.
05:51 PM andypugh: Drive the Z from the triangle wave output of a siggen.
05:55 PM pink_vampire: what do you mean HAL ?? and no Gcode?? how??
05:56 PM andypugh: pink_vampire: How have you used LinuxCNC so long without becoming friendly with your HAL file?
05:57 PM andypugh: loadrt siggen
05:57 PM andypugh: addf siggen.0 servo-thread
05:57 PM andypugh: net siggen.0.triangle stepgen.2.position.command
05:58 PM pink_vampire: so I need to edit the .hal file each time I want to use the machine as drum sander?
05:59 PM andypugh: No, you just load a different config.
06:00 PM XXCoder: yeah, thats nice side to how linuxcnc works
06:01 PM XXCoder: i had 3 while i was working on 3axis_tutorial
06:01 PM andypugh: (My milling machine can be 3 axis, 4 axis, gear hobber or horizontal mill, depending on which INI file I load in the config folder. There are a few common HAL files, a common tool table, and a few HAL files that wire the axes to motors in specific ways for the config selected)
06:02 PM pink_vampire: but I need to set the machine to specific location, and the run the sanding program, but you give me a very good idea, to computerize my sawing machine. that way
06:02 PM pink_vampire: but X86 computer will be over kill for that
06:07 PM pink_vampire: all it need is speed control (foot pedal), can be potentiometer, or PWM or frequency , and 2 buttons, one for needle up, and one for needle down, there is 2 photo interrupters that I can read and this way to know if the needle is up or down
06:07 PM pink_vampire: there is only one motor that go only in one direction
06:07 PM pink_vampire: andypugh: XXCoder ^
06:08 PM XXCoder: you could just use a arudino for that
06:08 PM andypugh: You could look at an Arduino for that. Or a 555 timer.
06:08 PM XXCoder: andy funny how we said it different ways but its exact same length (ignoring 555 timer part)
06:11 PM pink_vampire: LOL
06:12 PM pink_vampire: but I need to find a DC motor for it
06:12 PM pink_vampire: to control the speed on the AC motor is just not very easy at low speeds
06:13 PM andypugh: It can be done with a clever enough VFD. (SOme VFDs can work with an encoder)
06:18 PM pink_vampire: the whole machine cost me $65 so.. to get a VFD that will cost like super fancy brand new machine is not make sense in this case
06:19 PM andypugh: I am sure you can get a good-enough one for less than $650 :-)
06:21 PM pink_vampire: andypugh: it is a serger machine, for $650 you can get SUPER EPIC serger machine
06:22 PM andypugh: serger?
06:24 PM pink_vampire: https://www.google.com/search?q=serger+machine&tbm=isch
06:24 PM andypugh: Ah, right, I think I know those as “overlockers"
06:26 PM andypugh: My mum, a very keen sewer wanted one for decades, finally got one and could not figure out how to use it.
06:26 PM pink_vampire: overlock is the name of the stitch
06:26 PM JT-Cave: these new reading glasses suck, they are distorted on the edges so you can't glance at something on the side
06:27 PM andypugh: (For some reason I seem to spend a lot of YouTube time with Bernadette Banner. I think I just like the way she talks.)
06:28 PM XXCoder: jt hm think they got something wrong on your new glasses
06:28 PM pink_vampire: any of you use jewelers saw?
06:28 PM andypugh: It’s not like sewing is a big part of my life. Though I did once make some trousers, and a wedding dress.
06:29 PM XXCoder: isnt dress hard to make
06:29 PM JT-Cave: XXCoder, cheap reading glasses not prescription at all
06:29 PM XXCoder: ahh ok
06:29 PM andypugh: Sewing is a _lot_ like sheet metal work and rivetting.
06:29 PM JT-Cave: 1.75 diopter
06:30 PM JT-Cave: hmm all the Cinnamon Queens are inside time to close the door
06:58 PM Tom_L: JT-Cave, friday night... better turn on the disco ball for em
07:25 PM XXCoder: guys think https://www.ebay.com/itm/Empty-Plastic-Storage-Bottles-Pint-Pint/313119102242 will hold versa 2 oil fine?
07:26 PM Tom_L: vactra 2?
07:26 PM XXCoder: yeah
07:26 PM Tom_L: what plastic is it?
07:26 PM andypugh: if they can do paint i would expect them to be ok with oil
07:26 PM Tom_L: it _should_
07:27 PM Tom_L: but why not use the container it came in?
07:27 PM XXCoder: i have gallon, I want just pint
07:27 PM XXCoder: I plan to sell other 7 pints
07:27 PM Tom_L: andypugh, those look like shampoo bottles to me
07:27 PM Tom_L: ahh
07:27 PM Tom_L: good idea
07:27 PM XXCoder: probably is. certainly looks like em
07:28 PM Tom_L: it should be fine
07:31 PM Tom_L: sellin it for snake oil?
07:32 PM Tom_L: i keep some in a small squeeze bottle but it's a different plastic i think
07:32 PM Tom_L: andypugh, we're discussing brittish roads here and want to know what the zig zag lines on the road are for?
07:33 PM Tom_L: watching top gear...
07:33 PM andypugh: Near a zebra crossing? No parking and you must not overtake a stopped vehicle.
07:34 PM Tom_L: so you don't zig zag steer between em? :)
07:34 PM andypugh: Not if the police are watching.
07:34 PM XXCoder: heyyy https://www.ebay.com/itm/16-Oz-Plastic-Squeeze-Bottles-Graduated-Measurements-Food-Ketchup-Crafts-8-Pack/223966674526
07:34 PM Tom_L: maybe late on a friday night...
07:34 PM XXCoder: that is MUCH better
07:35 PM andypugh: Fewer bottles for more money?
07:35 PM Tom_L: XXCoder, those are better plastic for it too probably
07:35 PM XXCoder: hdpe is tough bastard of a plastic
07:35 PM Tom_L: go to uline and see what they have
07:36 PM XXCoder: looking
07:36 PM Tom_L: https://www.uline.com/Product/AdvSearchResult?keywords=plastic%20bottles
07:36 PM XXCoder: bah fine youre much faster than me lol
07:37 PM XXCoder: 36 is little too many at once
07:37 PM Tom_L: $2.12/case 16 oz
07:38 PM Tom_L: https://www.uline.com/BL_8184/Boston-Round-Squeezable-Bottles?keywords=plastic+bottles
07:38 PM skunkworks: CaptHindsight: did you get the matsurras? I am pretty sure that is the model we have - but with the geneva changer + in the mid 1980's
07:38 PM Tom_L: 25/case
07:38 PM skunkworks: CaptHindsight: looks very similar.
07:38 PM XXCoder: no thats per bottle price
07:38 PM Tom_L: mmm
07:38 PM XXCoder: $46 for one case heh
07:39 PM CaptHindsight: skunkworks: looks lie a deal, I'm not sure if I'd use them for much
07:39 PM CaptHindsight: seems a shame to go to scrap
07:39 PM CaptHindsight: lie/like
07:39 PM Rab: McMaster-Carr has cheap plastic bottles.
07:40 PM CaptHindsight: skunkworks: one has a 3k and the other a 6k rpm spindle
07:40 PM Tom_L: XXCoder, what's the box stores have in the 'travel' department for bottles?
07:40 PM XXCoder: dunno but prices is high for those usually I think
07:40 PM Tom_L: local and maybe cheaper
07:40 PM Tom_L: maybe worth a look
07:41 PM Rab: There's one type I use for tapping oil, after trying a couple different kinds...can't find the link
07:41 PM Tom_L: i get small 2oz ones with a needle in the lid
07:41 PM CaptHindsight: do the bottles indicate what plastic they are made of?
07:41 PM XXCoder: rab the curved tube one?
07:42 PM Rab: XXCoder, nah, the one with the nozzle tended to spit all over whenever I grabbed it.
07:42 PM XXCoder: i have decided to get that ebay one
07:42 PM CaptHindsight: they look like PET bottles
07:42 PM XXCoder: not too bad since thatm with oil would cost $8 usd each filled bottles, and i plan to sell at $10 each
07:42 PM Tom_L: the ketchup or shampoo bottle?
07:42 PM XXCoder: im not looking for massive profit. former heh
07:43 PM XXCoder: its hdpe, very strong
07:43 PM Tom_L: even if you don't sell em all, it keeps
07:43 PM XXCoder: yeah
07:43 PM XXCoder: cant ship em though heh
07:43 PM CaptHindsight: oh HDPE is tough
07:44 PM skunkworks: CaptHindsight: ours is 6k
07:45 PM Tom_L: skunkworks, did you get a touch screen on your rpi4?
07:45 PM skunkworks: no
07:45 PM skunkworks: have you tried one?
07:45 PM Tom_L: nope
07:45 PM skunkworks: would be kinda cool..
07:45 PM Tom_L: yeah
07:45 PM skunkworks: but they seem mostly expensive.
07:46 PM skunkworks: atleast the last time I looked
07:46 PM Tom_L: jt mentioned pyqt on it today or yesterday
07:46 PM XXCoder: if I tape it up a lot would it hold cap in while its being shipped? would have protectuon around it so it wont get squeezed
07:46 PM Tom_L: i wonder if that would work
07:46 PM Tom_L: the qtpyvcp stuff
07:46 PM skunkworks: like probe basic? I have not tried
07:46 PM XXCoder: skunkworks: I found pretty cool ones hold on
07:46 PM Tom_L: probe basic would be huge on it
07:46 PM Tom_L: but something like it yes
07:47 PM XXCoder: skunkworks: https://www.aliexpress.com/item/32976014070.html?
07:47 PM Tom_L: XXCoder, generally the liquids i get shipped to me are in a heat sealed bag now
07:47 PM Tom_L: for hazmat
07:47 PM XXCoder: its just first result, there is many more, with different options of connectors and touch screen
07:47 PM XXCoder: tom really interesting
07:48 PM Tom_L: if it spills, it's contained
07:48 PM XXCoder: i probably can add ziploc to protect it some more
07:48 PM skunkworks: was jt talking about trying a 64bit oscool
07:48 PM skunkworks: cool
07:48 PM Tom_L: hu
07:48 PM skunkworks: was jt talking about trying a 64bit os on the rpi4?
07:48 PM Tom_L: huh
07:49 PM XXCoder: tom i wouldnt full it to max because that leaves no heat expanson
07:49 PM Tom_L: ubuntu something
07:49 PM Tom_L: 19?
07:49 PM XXCoder: lots tape then ziplocs that should be fine
07:49 PM Tom_L: XXCoder, got any big heatshrink tube?
07:49 PM Tom_L: for the cap
07:50 PM XXCoder: ah thats an idea but wouldnt it melt plastic
07:50 PM Tom_L: not that quick
07:50 PM Tom_L: the kind they use for battery packs etc
07:52 PM skunkworks: hackintosh is dead..
07:52 PM XXCoder: yours or the project?
07:52 PM * skunkworks makes broad predictions..
07:53 PM skunkworks: apple switching to arm
07:53 PM XXCoder: ahh yea
07:53 PM XXCoder: back to old cpu type heh
07:53 PM Tom_L: they started with moto didn't they?
07:53 PM Tom_L: 68xx
07:54 PM skunkworks: they keep trying to go back to risc
07:55 PM andypugh: Apple have switched CPU 3 times already, I think that they now consider it no big deal.
07:55 PM snaked is now known as snakedkranz
07:55 PM Tom_L: 68000 was the first mac
07:56 PM andypugh: 68k -> PowerPC -> Intel -> ARM
07:56 PM Tom_L: considering they're closed source i bet that's a support nightmare
07:56 PM andypugh: OK, so twice so far, this is the third time.
07:57 PM andypugh: Not entirely closed-source. The Darwin kernel is OS.
07:58 PM andypugh: Here you are, Apple kernel on Github: https://github.com/apple/darwin-xnu
07:58 PM Tom_L: never messed with a mac but did play with a 68332 for a while
07:58 PM Tom_L: still have the 'books' on it
07:58 PM Tom_L: and the 2 'pink' books for the 68k
07:59 PM JavaBean: deadtree, or pdf?
07:59 PM Tom_L: deadtree
07:59 PM Tom_L: found pdf for some of it
07:59 PM JavaBean: shit should be in a museaum... or your will
08:00 PM Tom_L: hah
08:00 PM Tom_L: i liked that chip
08:00 PM JavaBean: which was the "mac color classic"?
08:00 PM Tom_L: i've no idea
08:01 PM Tom_L: the 68332 was more an 'industrial' chip
08:01 PM andypugh: Colour classic was 68040 I think
08:01 PM Tom_L: mine had the 'G' mask iirc
08:01 PM andypugh: Ah, no, 68030
08:01 PM Tom_L: motion control stuff
08:03 PM Tom_L: https://www.nxp.com/docs/en/data-sheet/MC68332TS.pdf
08:03 PM Tom_L: the TPU and QSM were great features
08:04 PM Tom_L: seems the sahara dust storm is gonna hit here this weekend
08:05 PM CaptHindsight: lots of bars and restaurants have just reopened here at 25% capacity
08:06 PM XXCoder: here some regions went back to phase 1
08:06 PM XXCoder: big growth of cases
08:06 PM XXCoder: bad enough that everyone in wa must mask up when outside
08:06 PM CaptHindsight: yoyo's
08:06 PM XXCoder: not really
08:06 PM XXCoder: western wa is still fine. its east side...
08:07 PM Tom_L: so the symptoms from the dust storm are similar to the covid symptoms...
08:08 PM CaptHindsight: but who ever heard of dust storms in Kansas?
08:08 PM Tom_L: yeah.. go figure :)
08:08 PM Tom_L: at least we didn't start it
08:09 PM XXCoder: yep usa-wise, wa state started it all
08:09 PM XXCoder: #1. now #23
08:14 PM XXCoder: i read new recent report that resistance to covid goes away in few months
08:14 PM XXCoder: hope not but who knows
08:15 PM andypugh: Does resistance change, or does Covid change?
08:15 PM XXCoder: resistance.
08:15 PM XXCoder: antibodies levels went down
08:15 PM andypugh: i did a home COVID test today. part of some random study.
08:16 PM XXCoder: its bit better than covid changing too fast for immunity
08:16 PM andypugh: Quite how you are meant to swab your throat without gagging or your nose without sneezing wasn’t explained.
08:16 PM Tom_L: andypugh, yeah they were doing random ones here as well
08:17 PM CaptHindsight: is it best to just keep on getting mildly infected until there is a yearly booster immunization?
08:17 PM Tom_L: due to overwhelming demand for 'exposure' cases they have quit testing and will call when they can get to you
08:18 PM XXCoder: tom wont get any better since they cut test budget
08:18 PM XXCoder: federal level anyway
08:18 PM Tom_L: that could change
08:18 PM XXCoder: hope so.
08:19 PM XXCoder: plague arent done
08:19 PM CaptHindsight: isn't it nice to have our pandemic response politicized
08:19 PM Tom_L: when the relapse hits
08:19 PM Tom_L: CaptHindsight, they will have a cure November 3rd
08:19 PM XXCoder: not likely
08:19 PM Tom_L: just saying...
08:20 PM XXCoder: ah lies
08:20 PM XXCoder: dunno
08:20 PM perry_j1987: I just took a break and watched a Sam Elliot movie
08:20 PM perry_j1987: The Man Who Killed Adolf Hitler and then Killed Bigfoot
08:20 PM perry_j1987: lol
08:21 PM perry_j1987: very well done movie
08:21 PM CaptHindsight: Sam Elliot with a moustache?
08:21 PM Tom_L: yeah
08:21 PM perry_j1987: of course
08:21 PM perry_j1987: it was his costar
08:22 PM CaptHindsight: I'm still catching up on missed foreign TV shows
08:22 PM CaptHindsight: or Hulu and Amazon only types
08:24 PM CaptHindsight: BBC has some clever ones
08:25 PM Tom_L: i watched a documentary on the kennedy assassination the other day with declassified documents etc
08:25 PM Tom_L: oswald didn't do it
08:25 PM Tom_L: it was pretty compelling
08:25 PM Tom_L: who knows...
08:26 PM CaptHindsight: there was one 15-20 years ago that had some hitmen claiming they were paid to do it
08:26 PM Tom_L: it was an accident
08:26 PM CaptHindsight: Sicilian
08:26 PM Tom_L: one of the secret service in the follow car did it
08:27 PM CaptHindsight: this one focus on the trees and fence where people claimed they heard shots
08:27 PM Tom_L: he was raising his gun and turning toward the sound when the car took off and it discharged
08:27 PM Tom_L: they proved 2 types of bullets
08:27 PM CaptHindsight: yeah similar
08:27 PM Tom_L: the 3rd casing in the book depository was explained too
08:27 PM CaptHindsight: well the evidence was conveniently destroyed
08:28 PM Tom_L: it was empty in the chamber to keep it clear
08:28 PM Tom_L: yeah by the secret service
08:28 PM CaptHindsight: i was too young at the time to be involved
08:28 PM Tom_L: to protect their own
08:29 PM snakedkranz is now known as snaked
08:29 PM Tom_L: i watched it live
08:29 PM CaptHindsight: quite a shocker
08:30 PM Tom_L: so far this version makes the most sense
08:30 PM CaptHindsight: well with the supposed killer, being killed and then his killed
08:31 PM CaptHindsight: so on and on
08:31 PM CaptHindsight: similar with his brothers assassination
08:32 PM CaptHindsight: Tom_L: what year is the documentary from?
08:32 PM Tom_L: i'm trying to remember
08:33 PM Tom_L: or see if it airs again
08:33 PM CaptHindsight: or the name
08:33 PM Tom_L: checking
08:38 PM skunkworks: Only thing I saw live was the challenger explostion..
08:38 PM CaptHindsight: https://youtu.be/2nmGS8rVuIM?t=142
08:39 PM skunkworks: The whole school was watching it becasue it was the first teacher in space.
08:39 PM CaptHindsight: i was out for most of those
08:39 PM CaptHindsight: watched lots of TV but never on those days
08:39 PM Tom_L: JFK Declassified: Tracking Oswald
08:39 PM Tom_L: i think that may have been it
08:40 PM CaptHindsight: https://www.history.com/shows/jfk-declassified-tracking-oswald
08:40 PM CaptHindsight: 6 part series
08:42 PM Tom_L: i'm not positive that was the one
08:43 PM CaptHindsight: haven't seen that one yet
08:43 PM CaptHindsight: might skim though it
08:43 PM Tom_L: i didn't watch the whole series, rather one evening so it might be a different one
08:43 PM CaptHindsight: i can find it based on your description
08:44 PM CaptHindsight: they all get reviewed and critiqued
08:44 PM Tom_L: they show things like the bullet entry size and compare it to the rounds
08:44 PM Tom_L: there were 2 different sizes
08:46 PM CaptHindsight: https://www.cnn.com/2020/06/26/europe/eu-coronavirus-travel-ban-us-intl/index.html
08:47 PM CaptHindsight: very likely given the state here
08:48 PM Tom_L: skunkworks, i saw that live too as well as apollo 13 etc
08:49 PM CaptHindsight: was out shopping when Apollo 13 made the announcement
08:49 PM Tom_L: that capsule is on display at our local space museum
08:49 PM CaptHindsight: I'm pretty sure that if anything earth shattering happens I'll be out
08:50 PM Tom_L: hah
08:50 PM Tom_L: the space program had gotten pretty ho hum up until that point
08:55 PM perry_j1987: every earth quake in my dad's life he's always been in a car during lol
08:55 PM perry_j1987: he's never felt one
08:56 PM Tom_L: CaptHindsight, that series wasn't the one i saw
08:56 PM Tom_L: just pulled up part of it
09:07 PM andypugh: g’night folks. (leaving the chat open, in case ye’all get interesring :-) )
09:08 PM Tom_L: later andy
09:11 PM skunkworks: Night
09:17 PM Tom_L: CaptHindsight, pretty sure it was JFK: The Smoking Gun 2013
09:18 PM Tom_L: amazon prime
09:29 PM CaptHindsight: hard to know what actually happened nearly 60 years ago with missing evidence
09:30 PM Tom_L: true
09:30 PM CaptHindsight: did anyone ever explain how the brain actually went "missing"
09:30 PM CaptHindsight: and the funny business with the x-rays
09:31 PM Tom_L: if you haven't seen that take on it you might want to
09:31 PM CaptHindsight: I'll watch it soon
09:32 PM CaptHindsight: but there was too much funny business surrounding this
09:32 PM Tom_L: agreed
09:33 PM CaptHindsight: it's been 30 years since I read what was released by the warren commission
09:34 PM CaptHindsight: https://www.archives.gov/research/jfk/warren-commission-report
09:34 PM CaptHindsight: https://www.archives.gov/files/research/jfk/warren-commission-report/appendix-09.pdf
09:35 PM CaptHindsight: Autopsy Report and Supplemental Report
09:36 PM CaptHindsight: how do you lose a brain in a case like this?
09:36 PM Tom_L: on purpose
09:39 PM CaptHindsight: funny how that happened
09:41 PM Tom_L: the autopsy wasn't done in dallas in spite of the texas law
09:43 PM CaptHindsight: I'm not sure how many areas of the US allow for autopsy's outside of the area where the death occurred
09:44 PM CaptHindsight: why some small townish county coroners have had some high profile cases
09:45 PM CaptHindsight: what do you do about things like this?
09:45 PM CaptHindsight: nobody cares enough
09:47 PM CaptHindsight: assassinations, wars, elections etc etc
09:48 PM Tom_L: hickey falsified his statement about his weapon where 11 eye witnesses saw a different story
09:48 PM Tom_L: iirc 9 were secret service
09:51 PM CaptHindsight: we don't watch the watchmen here
09:51 PM CaptHindsight: we don't police the police
09:52 PM Tom_L: we don't live in a perfect world
09:52 PM CaptHindsight: not even close
09:52 PM CaptHindsight: we invite corruption
10:15 PM CaptHindsight: but I will say that it's working pretty well for the top 1%
10:15 PM CaptHindsight: and that is no coincidence
10:15 PM Tom_L: all thru history
10:19 PM flyback: <flyback> Disk /dev/hda: 74.54 GiB, 80026361856 bytes, 156301488 sectors
10:19 PM flyback: <flyback> Disk model: ST380011A

10:19 PM flyback: <flyback> Disk model: ST3160023A
10:19 PM flyback: <flyback> /dev/hd* = old linux ide subsystem with full dma on/off control :D
10:19 PM flyback: I did it
10:19 PM flyback: and just in case cause my 2nd silicon image sil680 2 port pci ide card comes tomarrow
10:20 PM flyback: so each of my two data recovery boxes has 2 pci ide cards
10:20 PM flyback: 1 promise ata133 = full speed, lightely damaged hd's imaging or drives with no dma problems
10:20 PM flyback: 1 silicon image = pio0-4 no dma for drives wqith broken dma or really in bad shape to help recover the last few sectors
10:26 PM CaptHindsight: nobody seems to want to do anything about it either
11:29 PM veegee: So I made a mistake patching the concrete floor
11:29 PM veegee: The mistake was cleaning it
11:29 PM veegee: No matter how much you clean, there's still going to be some contamination of oil or TSP or whatever else
11:29 PM veegee: and it prevents the patch cement from sticking to it
11:30 PM veegee: So for the next set of holes, I decided to not clean at all and instead just make the holes larger to expose fresh white concrete with my rotary hammer
11:30 PM veegee: that was easier and guaranteed a clean surface
11:31 PM veegee: The concrete patch adhered to it extremely well and was ready to surface grind in 48 hours. It came out so smooth, I can't tell the boundary between the original concrete and the patch when I run my finger across it
11:31 PM veegee: The stuff cures way too fast though. Like it gets harder/dryer within five minutes while it's in the bucket and apparently you shouldn't add more water or it'll weaken it (?)
11:32 PM veegee: So I guess I'll go for the regular concrete patch compounds that don't start setting literally as you're applying it
11:34 PM veegee: Also, chipping away at the existing holes with a rotary hammer and chisel bit made very nice, rough and jagged cut marks for the cement to adhere to
11:36 PM CaptHindsight: have a link to the patch used?
11:36 PM XXCoder: we need to rip up driveway and replace it here
11:36 PM XXCoder: its in really bad condition, whoever did it didnt mix correctly or let it dry too fast
11:37 PM veegee: CaptHindsight https://www.homedepot.ca/product/sakrete-fast-patch-15-kg/1000109213
11:37 PM veegee: I'm thinking might as well mix my own because that's expensive and I used the entire container for like 20% of the total holes to patch
