12:12 AM miss0r: goodmorning
12:36 AM Tom_L: i finished the large one for my kid since he can't go to his vo'tech class
12:36 AM Tom_L: he had the block squared
12:37 AM miss0r: What about the undercut portion?
12:38 AM Tom_L: ?
12:38 AM Tom_L: it's not a perfect mill
12:38 AM Tom_L: but it's alot closer that it was
12:38 AM miss0r: oh, not that... :) The operation where you break the "boxes" apart from eachother
12:39 AM miss0r: using hotsnot to fixate the innards as you go
12:39 AM Tom_L: you need larger circles for that
12:39 AM miss0r: Couldn't you do that with a slitting saw?
12:39 AM Tom_L: i don't think the instructors wanted their cncs broke
12:39 AM miss0r: hehe
12:39 AM Tom_L: not really
12:40 AM Tom_L: the remaining material is more the shape of a triangle
12:40 AM Tom_L: you'd have to have a pretty thin small blade
12:41 AM miss0r: hmm.. I don't see why that should be a problem :D
12:41 AM Tom_L: i'll send it ...
12:41 AM miss0r: What are you waiting for! :D go go go
12:41 AM * miss0r is unsure of any international postal routes at the mooment
12:42 AM Tom_L: since i went thru my axis last week it's cutting alot more true than it had been
12:42 AM miss0r: You ajusted it?
12:42 AM Tom_L: in hal
12:43 AM miss0r: Damn modern technology... why do it with a spanner when you can move about some bits'n bytes
12:43 AM miss0r: :)
12:50 AM XXCoder: Tom_L: dang 5 cubes
12:50 AM XXCoder: youre crazy
12:50 AM XXCoder: no, 6
12:58 AM Tom_L: 6?
12:58 AM XXCoder: pink_vampire: saw guy use lathe to make turner cubes heh
12:58 AM XXCoder: tom yeah http://tom-itx.no-ip.biz:81/~webpage/cnc/Cube/Turners_cube2.jpg
01:01 AM miss0r: that is 6 cubes
01:01 AM Tom_L: oh i see what you mean
01:01 AM miss0r: I've never made one of those.. I think I might at some point, should I get the spare time to handle it :D
01:03 AM Tom_L: the medium one, my oldest kid did at vo'tech a few years back now
01:04 AM miss0r: I never had any formal education with machining, so sadly there was never a course where I had to make one
01:04 AM XXCoder: me either
01:04 AM Tom_L: me either
01:04 AM Tom_L: :)
01:04 AM miss0r: :]
01:04 AM XXCoder: i still find it truly funny that i joined here before i got my job
01:04 AM XXCoder: :}
01:05 AM miss0r: Must be the good company :ţ
01:05 AM XXCoder: i was starting to get oarts to build rough cnc machine to make better cnc machine
01:05 AM Tom_L: XXCoder, i figured you'd been there a long time
01:05 AM XXCoder: yeah work 5 years now. i joined here 7 years ago or so
01:05 AM miss0r: hmm.. I wonder when I joined here. I honnestly can't remember
01:05 AM miss0r: a few years atleast
01:06 AM Tom_L: i've been here a while but i've followed lcnc from it's infancy
01:06 AM XXCoder: 8 now I think acually, it was year or 2 before I even joined job training place
01:06 AM * miss0r bows to the two veterans
01:06 AM XXCoder: tom I found lcnc when I was looking for a way to control a machine
01:07 AM miss0r: is there still an active bot in here? I think I could find out through that
01:07 AM Tom_L: not sure how far back it goes
01:08 AM miss0r: 2012 it seems
01:08 AM miss0r: but it is devided into seprate days. I don't want to plow through that :D
01:08 AM Tom_L: yeah i didn't start logging right away
01:08 AM miss0r: Do you have a dump file or something? :D
01:08 AM Tom_L: and i don't even know where my old old logs are
01:09 AM Tom_L: back to ~90ish
01:09 AM XXCoder: http://psha.org.ru/irc/%23emc/2014-05-14.html
01:09 AM XXCoder: that was when i got rails!
01:10 AM XXCoder: 6 years ago, joined bit before, buying stuff was very slow
01:10 AM Tom_L: i thought his was down
01:10 AM miss0r: hehe
01:10 AM miss0r: good'ol days
01:10 AM miss0r: bah. I don't want to do this :) It will take forever
01:11 AM Tom_L: yeah i should be asleep anyway
01:11 AM XXCoder: :)
01:12 AM miss0r: tom_L: could you do a 'grep miss0r *' for me? :)
01:12 AM miss0r: Having local file access makes it easier :P
01:12 AM miss0r: actualy, that might be a huge file...
01:13 AM miss0r: perhaps add 'grep miss0r * > output'
01:14 AM Tom_L: maybe another day
01:14 AM miss0r: or I *could* do a script using wget to download the entire log and run it myself...
01:14 AM Tom_L: gnite
01:14 AM miss0r: Bah. I Should return to cleaning the shop. This is procastrinating at its best
01:14 AM miss0r: good night
01:15 AM XXCoder: :)
01:15 AM miss0r: My die grinder died yesterday
01:15 AM miss0r: while grinding the ID of my new 3-jaw mounting adaptor.
01:16 AM miss0r: Which was kind'a a bump in the road
01:16 AM XXCoder: doh sucks
01:16 AM miss0r: yeah, but its time had come. Its from 97 or 98 ish
01:17 AM miss0r: got a new metabo GE 710 compact... one of those with a long reach spindle.
01:17 AM XXCoder: oh man
01:17 AM XXCoder: zeesan
01:18 AM XXCoder: been long time since i saw that name
01:18 AM miss0r: Getting nostalgic, are we?
01:18 AM miss0r: :)
01:18 AM XXCoder: zee meh
01:18 AM XXCoder: hes cool but then sometimes he goes off and eh
01:19 AM miss0r: hehe sounds like many people in here
01:19 AM XXCoder: think he left sortly after he pissed off other person off and left lcnc
01:19 AM miss0r: myself included
01:19 AM XXCoder: nah what we have is pretty tame
01:20 AM miss0r: I like tame :)
01:21 AM miss0r: heck it, i'm going to download that log list.
01:21 AM * miss0r fires up a terminal
01:21 AM XXCoder: 60k new cases or so. whee
01:21 AM miss0r: Here in Denmark the curve is going the right way
01:22 AM XXCoder: usa got out of exponental a while ago but still increasing fas
01:22 AM XXCoder: 671k. usa #1 yayyy
01:22 AM XXCoder: if we followed spanish flu of 1918 naming of virus, then it'd be called usa virus
01:23 AM miss0r: go USA! yay... :-/
01:23 AM XXCoder: yeah
01:29 AM roycroft: the curve is flattening here in oregon faster than in the nation as a whole
01:29 AM XXCoder: 1000 cases here in piece county
01:29 AM miss0r: that is alot
01:29 AM XXCoder: not too bad compares to seattle, let alone new york, new york!
01:29 AM roycroft: washington is where it all started in the usa
01:29 AM XXCoder: roy yep yet we are at what #10 state now
01:29 AM roycroft: something like that
01:29 AM XXCoder: we locked down pretty dang fast
01:29 AM roycroft: we're #36
01:29 AM roycroft: and #29 by population, so we're doing pretty well
01:29 AM XXCoder: not bad
01:29 AM roycroft: we were #32 a week ago
01:29 AM roycroft: i was at the market today getting groceries, and i'd say 80% or more of the people were wearing masks
01:29 AM roycroft: that's a huge help
01:29 AM XXCoder: indeed
01:29 AM XXCoder: i have one now, and will get another soonish
01:30 AM XXCoder: it seems to me more and more that masks will be standard thing
01:30 AM roycroft: but i have several boxes in stock already, of various thicknesses
01:31 AM roycroft: they will be until there's a vaccine
01:31 AM XXCoder: which would be interesting because it would also wipe some stuff out, like cold
01:31 AM roycroft: except the base will not wear them
01:31 AM XXCoder: base? is that whistle for something?
01:31 AM roycroft: and anything but an n95 mask will not keep one from getting it
01:32 AM roycroft: the lesser masks only help prevent spreading it
01:32 AM XXCoder: exactly
01:32 AM roycroft: the mouth-breathers who worship trump
01:32 AM XXCoder: japan and some other places already wear masks when sick for few years
01:32 AM XXCoder: this just hammers in nail nore
01:32 AM roycroft: i expect that folks will keep masks in stock at home in the future
01:33 AM XXCoder: yeah
01:33 AM roycroft: handshaking may be gone forever
01:33 AM XXCoder: like I said my ultimate plan is to have 5 masks for weekly
01:33 AM roycroft: there will be a number of significant cultural changes after the pandemic
01:34 AM roycroft: speaking of mouth breathers
01:34 AM roycroft: there's a huge rally at our state capitol planned for may 1 and may 2 to protest the sip order
01:35 AM roycroft: which will, of course, accomplish nothing but prolong it, because they'll be spreading the virus love at the rally, and we'll have another spike
01:35 AM XXCoder: i saw picture of window thats showing full of protestors and another one window showing full of zombies
01:35 AM XXCoder: comprasion was... apt.
01:42 AM miss0r: alright.. finally done scripting. Now I am downloading the entire log :]
01:43 AM miss0r: ...procastrination
01:43 AM XXCoder: lol
01:43 AM miss0r: I hope I don't sufficate his bandwich
01:43 AM XXCoder: reminds me of that weird superhero that has power to be arrive late
01:43 AM miss0r: I have a friend like that
01:43 AM XXCoder: that includes his own death
01:44 AM miss0r: He is actualy know for it
01:44 AM miss0r: In denmark we have some traditions about special occation lunches.. like easter lunch ect...
01:44 AM miss0r: Basically its all sort of nice stuff that you put on, and this is important, rye bread.
01:45 AM miss0r: Imagine having a friend who was supposed to show up with the rye bread(The easiest of all tasks) because he is lazy, and then manages to get there two hours late? :)
01:45 AM XXCoder: bleh heh
01:46 AM miss0r: Its been a few years since that incident, and this is still a subject we tease him with. When we plan stuff like this, we alwasy go out of our way to mention he has to handle dessert or something that won't be needed from the get-go
01:46 AM XXCoder: smart
01:47 AM miss0r: bah... This is taking for ever.. I should've hadded -j 20 or something to the parallel command
01:47 AM miss0r: At the moment I am only downloading with two threads
01:47 AM miss0r: I guess I should clean the shop while it downloads. Back in a bit
01:49 AM miss0r: I am actualy looking forward to seeing how much data(kb/mb/gb) wise has been generated in this channel since 2012... :)
01:49 AM XXCoder: :)
01:49 AM miss0r: and how many KBs worth of data I have typed in that period.
01:49 AM miss0r: :)
02:01 AM miss0r: ls
02:01 AM miss0r: .. oops
02:01 AM XXCoder: .
02:01 AM XXCoder: ..
02:04 AM miss0r: apparently the first comment I can see with my name on it is from 2014-03-02
02:04 AM XXCoder: command not found
02:05 AM XXCoder: cool :) can you find when i joined?
02:05 AM XXCoder: i thought 2012 but maybe not
02:05 AM miss0r: sure, hang on
02:09 AM miss0r: apparently 2014-03-15
02:09 AM XXCoder: interesting. hey youre elder to me apparently lol
02:10 AM miss0r: oh yeah
02:10 AM miss0r: but I am older than this in here. which is odd.
02:10 AM miss0r: What I found on that date, clearly is not my first comment
02:11 AM XXCoder: what did i say on 3-15?
02:11 AM miss0r: 2014-03-15.html:<a href="#13:31:46" name="13:31:46" class="time">[13:31:46]</a> <span class="person" style="color:#%00x%00x%FFx">&lt;XXCoder&gt;</span> heys
02:11 AM miss0r: 2014-03-15.html:<a href="#13:33:09" name="13:33:09" class="time">[13:33:09]</a> <span class="person" style="color:#%00x%00x%FFx">&lt;XXCoder&gt;</span> curious on what linuxcnc can do
02:12 AM miss0r: I just looked at mine. it is the first
02:12 AM XXCoder: thats first for me yeah
02:12 AM XXCoder: i wasnt sure what lcnc was then
02:12 AM miss0r: I was having a private conversation with archivist, then he invited me in here to continue the convo.
02:12 AM miss0r: So it fits
02:12 AM XXCoder: archivist hope hes doing ojk
02:13 AM miss0r: yeah
02:14 AM miss0r: In that timeperiod this channel has generated 359MB worth of data. But I did not remove all the html nonsense from that statistic, so probably around half
02:16 AM miss0r: and of that I managed to do 3.9MB worth of data.. (again probably half, if you sifen out all the html stuff)
02:16 AM miss0r: holy... you did 20MB
02:16 AM miss0r: going through some keyboards, are we? :)
02:17 AM rmu|w: even the 359mb seem a lot
02:17 AM XXCoder: mis nah still same keyboard. its umm
02:17 AM miss0r: rmu|w: No arguement there. But keep in mind that half of that(probably) is the HTML headers ect
02:17 AM XXCoder: 14 years old? not syre
02:18 AM XXCoder: some keys have shiny indentions due to being hit so often
02:18 AM XXCoder: most of em actually, some more than others
02:18 AM miss0r: now that I have my answer on when I joined, I don't much feel like doing alot more sorting to get the correct data amount. I should be cleaning the shop, instead I am here scripting some non critical stuff :)
02:18 AM XXCoder: yeah go clean up man
02:19 AM XXCoder: or chips dragon will spawn and eat you up
02:19 AM miss0r: but come one. Can we atleast agree it was somewhat interresting? :)
02:19 AM XXCoder: yeah
02:20 AM miss0r: Alright. I have the data.. Send me questions, and I will reject to answer them. Now back to the cleaning
02:20 AM rmu|w: miss0r: my (incomplete) irc logs going back to '99 are just 190mb ;)
02:20 AM miss0r: that is alot more time, mind you
02:20 AM miss0r: and that log does not contain HTML stuff
02:20 AM miss0r: (I'm assuming)
02:20 AM rmu|w: no html, and every channel i was on
02:21 AM XXCoder: unless its html code paste heh
02:21 AM miss0r: XXCoder: Haha. Yeah. That script I was planning in my head to clean it up just got more complicated - I did not think of that
02:21 AM * miss0r now presses play on the audio book and dissapears into the shop
02:22 AM rmu|w: but storage in that kind of order of magnitude is cheap nowadays
02:23 AM XXCoder: indeed
03:15 AM Loetmichel: mornin'
03:15 AM Loetmichel: *well*... running is supposed to be good for the body... Have a 42" TFT on the workbench i have to design an enclosure for. Walking there, getting four measurements. Walking to the CAD desk. Designing a little. Already forgot two measurements. Back to the workbench it is... repeat at nauseam... :-)
05:15 AM jthornton: morning
05:15 AM XXCoder: yo
05:17 AM Deejay: hi
07:01 AM Tom_L: morning
07:01 AM XXCoder: yo
07:02 AM Tom_L: 35°F
07:17 AM jthornton: 54°F
07:31 AM pink_vampire: 118°De
07:38 AM gregcnc: 3" snow
09:14 AM skunkworks: Tom_L: cool!
09:15 AM skunkworks: schools here closed for the year..
09:42 AM andi_: skunkworks: may i ask: where are you from?
10:00 AM unterhaus: it's 38F here right now, would be nice if winter would go away. But I guess this is fairly normal, planting season really starts in mid-may
10:36 AM jymmmm: unterhaus: but greenhouse seedling season started last month =)
10:38 AM jymmmm: Yesterday was the warmest this year 73F
11:11 AM Tom_L: skunkworks, he's not very happy since they're home they're loading him up with online paperwork instead...
11:25 AM Tom_L: mmm UK just added another 3 weeks vacation...
11:31 AM jymmmm: paid?
11:33 AM Tom_L: doubtful
11:34 AM jymmmm: Is carbn fibr fire PROOF?
11:34 AM Tom_L: google what it's made from
11:35 AM Tom_L: the polimers are
11:36 AM Tom_L: Flammability: Though Carbon Fiber is constituted of carbon which is flammable, the fiber itself dose not flare up even if ignited by flame of match or gas burners. If heated up higher than 400 degree C together with some fuel, the fiber slowly burns (oxidized) but stops burning right after the burning fuel is removed.
11:42 AM Loetmichel: carbon fibre is to densely packed.
11:42 AM Loetmichel: needs more energy to free the carbon atoms out of the bond than is gained by burning said atoms
11:43 AM Loetmichel: -> fire goes out as soon as no more external energy is fed to it
11:43 AM andypugh: Tom_L: Another 3 weeks of isolation. It isn’t turning in to 3 weeks more furlough, at least fo rus.
11:44 AM net|: does anyone know if hell is real ?
11:46 AM net|: its almost like there is an AI that hates me every day
11:46 AM net|: my cerebellum makes more noise than my ass
11:46 AM jymmmm: net|: You are there, you tell us
11:46 AM Tom_L: andypugh, hope so.. i'm gettin kinda tired of this
11:47 AM Tom_L: did a turners cube yesterday out of boredom
11:47 AM net|: whatever it is wants me to do more bad stuff all the time almost like the devil wants to get me in trouble every day
11:48 AM Tom_L: he just wants to keep you there for company
11:49 AM net|: it wants me to die and i have never physically done anything to hurt anyone
11:49 AM net|: for the last 8 years ive had quantum tunnels in my head
11:51 AM rmu|w: who didn't
11:52 AM net|: every day is like looking like a retard with my head making snapping noises probably close to 50 to 100 each day you literally have to kink your neck feel where the brain zaps are then snap them out.
11:52 AM net|: they talk too which makes it stranger, says its my friends and neighbors talking to me
11:52 AM fenugrec: cluster migraine ? #diagnosticCNC
11:53 AM rmu|w: net|: stop watching mr. robot
11:54 AM rmu|w: if you hear things/people that objectively are not there you should get professional help
11:56 AM net|: from the ghostbusters maybe
11:57 AM net|: the specialists in canada only perscribe drugs for it
11:57 AM net|: no one even has eeg or ai's that could look
11:57 AM net|: our governments hide the fact that ultrasonic frequency's can damage brains
11:58 AM net|: pyramid frequency really messed me up
11:58 AM net|: also hearing tests
12:00 PM net|: ultrasonic can open up the blood brain barrier and let stuff in
12:03 PM gregcnc: check your microwave for leakage
12:04 PM rmu|w: hmm. seems you _can_ open the blood brain barrier with focused ultrasound
12:04 PM rmu|w: but that seems to involve something like a lithotripter (nierensteinzertrĂĽmmerer)
12:05 PM Loetmichel: that net| guy sounds a bit delusional.
12:06 PM Loetmichel: rmu|w: not exactly a "hideable in an FBI van" device if you ask me.
12:06 PM fenugrec: wonder what brought him here
12:07 PM rmu|w: Loetmichel: and usually you have to be submerged in water
12:07 PM rmu|w: doesn't really work through air
12:08 PM rmu|w: probably too much refraction
12:09 PM Loetmichel: rmu|w: indeed
12:09 PM Loetmichel: thats what i meant with "not exactly small"
12:09 PM Loetmichel: the tank alone would be a bit big
12:09 PM Loetmichel: not counting the mutiple KW sized ultrasonic drivers and electronicx
12:10 PM rmu|w: i think you could fit it into a standard shipping containers, those things are not that big
12:10 PM rmu|w: basically a big bathtub and a roentgen aiming device
12:11 PM rmu|w: fun fact, those things were first developed by dornier, german airplane manufacturer
12:12 PM rmu|w: they noticed some particular damages in the focal point of the nose cone when attempting ultrasonic flight
12:12 PM rmu|w: and somehow developed that into ultrasonic litrotripters
12:20 PM Loetmichel: yeah, point of those things is that you have multiple ultrasonic devices that alone dont damage tissue but where all the sound cones meet there is an energy peak that can shatter hard substance
12:29 PM rmu|w: the ultrasound is focussed via some sort of parabolic mirror
12:29 PM rmu|w: or rather elliptic
12:29 PM rmu|w: 25 years ago they didn't have that many emitters, 2 or 3 iirc
12:35 PM Rab: I've had that done twice. But I was out both times, didn't get to see the tank.
12:36 PM Rab: It allegedly leaves a cone-shaped bruise through the body, which didn't feel too good. But better than a kidney stone.
12:39 PM Rab: Blood brain barrier still intact, AFAIK.
01:34 PM skunkworks: andi_: I am in the us midwest.. Western wisconsin
01:36 PM Tom_L: skunkworks, how's the encoder coming along?
01:37 PM skunkworks: slow
01:37 PM Tom_L: seems to be no rush these days ehh?
01:38 PM skunkworks: It has been pretty nice.. Working from home with lots of time with the kids.
01:38 PM skunkworks: Makes me re-think life
01:39 PM Tom_L: yes it does
01:40 PM Tom_L: mine were out in the shop while i was running my little mill having a pissing contest over which one runs the biggest parts at work
01:41 PM Tom_L: i reminded them they didn't know what a gcode was before i showed em on the little mill
02:47 PM Thorhian: I found a cheap 2400W 48V power supply. $90. I only need at most 1500W to 1800W so I don't think I'd push it.
02:48 PM Thorhian: With that I think I can use that 1800W BLDC motor Rab
02:58 PM Rab: Thorhian, I like to derate the cheap PSUs by 2x, but that's probably pretty good. Especially if you keep it cool.
02:59 PM Rab: Got a link to the PSU?
02:59 PM Thorhian: Yeah, I figured I would be under its supposed max load by around 1kW at peek power, so it's probably fine. I just need to make sure I have a 240V circuit to use it with in my garage lol
03:01 PM Rab: I put a NEMA 6-20 outlet on my clothes dryer circuit and swapped my mill and reflow oven, before I ran 240V everywhere in the shop.
03:01 PM Thorhian: Rab: https://usa.banggood.com/AC-200V-250V-To-DC-48V-50A-2400W-Power-Supply-For-ZVS-High-Frequency-Induction-Heating-Module-p-1279188.html?rmmds=search&cur_warehouse=CN#jsReviewsWrap
03:05 PM Rab: Hmm, looks like that was an Emerson modular power supply designed for telco use in a previous life.
03:05 PM Thorhian: The connector looks kind of odd, but I figure that can be worked around?
03:06 PM Rab: Probably. But you will need a secure connection for that much current.
03:06 PM Thorhian: Yep.
03:49 PM Deejay: gn8
03:51 PM gregcnc: What kind of BLDC motor are we using here?
03:58 PM Rab: gregcnc, this one I think: https://www.amazon.com/dp/B07CCNPW6G
03:59 PM XXCoder: i keep forgetting, which is better for spindle, ac or dc?
04:01 PM gregcnc: doesn't matter much. all really depends on the control
04:03 PM gregcnc: DC should be cheaper
04:05 PM gregcnc: you need to understand ratings to be sure duty cycle is comparable
04:06 PM gregcnc: if that amazon control has regen braking that could be fun with powersupplies
04:26 PM Tom_L: will any 3phase ac mototr work with a vfd?
04:30 PM pcw_home: Should...
04:31 PM pcw_home: older motors may have insulation failures with the HF drive though
04:37 PM Tom_L: ideally i could find a small frame 1/2-3/4hp 3phase motor i could use as a spindle motor and get a vfd to drive it
04:40 PM Rab: Tom_L, I've a lot of people recommend these for <1hp lathe conversions: http://www.consew.com/List/Machine-Stands/Servo-Motors
04:40 PM Rab: +seen
04:41 PM Rab: They sell on eBay, prices aren't outrageous.
04:42 PM Rab: Not sure if there's any option for external speed adjustment, though.
04:42 PM Tom_L: are those from sewing machines?
04:43 PM Tom_L: a guy here tried to convert one that was for a sewing machine and blew up the control trying to interface to it
04:44 PM Tom_L: those may be something different
04:45 PM Tom_L: i've also seen something that looks very similar that a company has a kit for the sherlines for but they want way too much for it
04:47 PM Tom_L: i'm in no rush, it's working the way it is. just wish the spindle had more power
04:48 PM XXCoder: you know how to rebuild em? could be cheap one ot get power
04:50 PM Tom_L: https://glockcnc.com/sherline-spindle-motor-upgrade-brushless/
04:50 PM Tom_L: they want alot for that
04:53 PM Tom_L: 0-10v control which is what i use now
04:56 PM Tom_L: i suppose the control itself would have the speed feedback instead of an encoder back to lcnc
04:58 PM Thorhian: Rab: I don't think the motor has regen breaking. It seems someone has asked that question on amazon already.
04:58 PM Thorhian: https://www.amazon.com/gp/product/B07KF8M5W6/ref=ask_ql_qh_dp_hza
04:59 PM Thorhian: Also, I got my spindle today! :D It's heavier than I thought it would be, but I guess that is to be exptected/is a good thing.
05:05 PM _unreal_: Rab, I'm loving this I'm up $2k
05:05 PM _unreal_: stocks
05:17 PM gregcnc: your aren't up until you sell
05:21 PM _unreal_: Thats whats killing me for the stocks I've purchased IF/when they get back to there jan/feb rage I'll have 8k
05:21 PM _unreal_: then I'll sell
05:22 PM gregcnc: in for the long haul then?
05:23 PM gregcnc: dang, they just cancelled school for the rest of the year
05:24 PM Tom_L: lucky you?
05:25 PM gregcnc: one kid gets about 30 minutes of school work, the other doesn't want to do any
05:25 PM Tom_L: remove the distractions
05:38 PM jthornton: Missouri just got 2 more weeks of stay at home order
05:41 PM wellindex: back to the cave
05:41 PM _unreal_: florida is hardly closed
05:41 PM _unreal_: any one who can do curb side more or less or work from home is good to go
05:42 PM _unreal_: its funny even the casinos are in on the auction. you pull up give them yoru money and leave
05:42 PM _unreal_: LOL
05:50 PM Tom_L: jthornton, ours was extended i think til the 3rd
05:51 PM jthornton: yea ours was extended to the 3rd but checking it's 9 more days
05:51 PM jthornton: no big deal I don't go anywhere anyway and with baby chicks on the way I'll be busy
05:52 PM jthornton: the good thing is the number of new cases is on the decline
05:53 PM jthornton: https://health.mo.gov/living/healthcondiseases/communicable/novel-coronavirus/img/epi-daily-case-number-reported.jpg
05:55 PM XXCoder: jt yeah
05:55 PM MacGalempsy: hello
05:55 PM XXCoder: growth of cases have been out of exponental for few days now
05:55 PM jthornton: XXCoder, what was that link you had on world wide numbers?
05:55 PM XXCoder: https://gisanddata.maps.arcgis.com/apps/opsdashboard/index.html#/bda7594740fd40299423467b48e9ecf6
05:55 PM jthornton: thanks
05:56 PM XXCoder: on bottom right there is "logarithmic"
05:56 PM XXCoder: click it
05:56 PM XXCoder: when its rising there it means exponental growth less than 45 angle upwards means below exponental
05:57 PM XXCoder: you can see how flat feb is. its due to lack of tests.
05:57 PM MacGalempsy: the numbers say 630K confirmed in the US, but there probably aren't even that many tests yet
05:58 PM XXCoder: 700k almost actually
05:58 PM XXCoder: and on top right theres number of tests.
05:58 PM XXCoder: its at 2.4 million
05:58 PM XXCoder: so yes theres been lots of tests.
05:58 PM jthornton: 3.5 million
05:58 PM XXCoder: 3.5m now actually lol outdated info
05:59 PM XXCoder: and cases number is very underreported, because they refuse to test people that have minor symtoms
05:59 PM jthornton: we are number one for total cases and number of deaths by country
05:59 PM XXCoder: if I ever get it, I would get a minor case of deads
06:00 PM jthornton: ouch
06:00 PM XXCoder: fun isnt it heh
06:00 PM XXCoder: it affects lungs and mine is damaged enough thank you
06:01 PM jthornton: in Missouri 3.1% die
06:02 PM XXCoder: people keeps saying 3% is small and theres more deaths in flu cases
06:02 PM XXCoder: uh its 0.1% at worse for flu
06:02 PM XXCoder: average is what 0.01%
06:02 PM XXCoder: it really annoys me
06:03 PM jthornton: Missouri folks who got it and recovered are donating blood to help the ones in bad shape
06:03 PM jthornton: yea it's way worse than the old flu's we knew and loved
06:04 PM XXCoder: yeah. we really should teach stats and critical thinking in classes
06:04 PM XXCoder: because damn
06:04 PM Tom_L: jt did you see my yesterday's quarantine project?
06:04 PM jthornton: no, busy with brooder design and building and missed it
06:04 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Cube/Turners_cube2.jpg
06:05 PM Tom_L: the youngest started it at vo'tech (squared the block) so i told him we could finish it here since he's out of school
06:06 PM Tom_L: the big block. i did the other one a while back
06:07 PM jthornton: cool
06:07 PM jthornton: do you keep flipping it for each side one level deep or do the whole side?
06:07 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Cube/Turners_cube3.jpg
06:08 PM Tom_L: his brother did the other one couple years ago in the same class
06:08 PM Tom_L: run one whole side at a time
06:08 PM Tom_L: 6 ops
06:08 PM jthornton: CNC or manual?
06:09 PM Tom_L: https://www.youtube.com/watch?v=-iak87E3ja0
06:10 PM Tom_L: cnc of course
06:10 PM jthornton: chips ahoy
06:10 PM Tom_L: that
06:10 PM Tom_L: that's about that spindle's limit
06:11 PM Tom_L: they were chuckling since the mills at their work run 400ipm
06:12 PM XXCoder: jt if youre bored make farmbot heh
06:12 PM jthornton: is their work shut down?
06:12 PM XXCoder: nice video!
06:13 PM jthornton: I anything but bored... 12 days till the chicks ship from Lebanon
06:13 PM jthornton: 2-3 days in transit
06:13 PM Tom_L: one got layed off but the other one is still working but shorter hours
06:13 PM XXCoder: i am bah but not that skilled too
06:13 PM jthornton: I forget exactly
06:13 PM XXCoder: shorter hours for me too
06:13 PM XXCoder: only 32 hours this week and forseenable future
06:13 PM Tom_L: they've got defense contracts so they are staying open
06:13 PM jthornton: I'm not doing any outside work right now
06:13 PM Tom_L: just hard getting supplies
06:13 PM XXCoder: same reason shop I work for stays open
06:14 PM jthornton: I have a job to do but putting it off for a while
06:14 PM Tom_L: the 2nd one was furloughed for 2 weeks but they are staggered
06:15 PM XXCoder: LOL dumb spam email title. weilers! weilers! Weilers! lol
06:15 PM XXCoder: spam is about welders
06:16 PM jthornton: it's gotta be really tough on young people who work in a service industry like food etc
06:16 PM Tom_L: i've been off since i got back from a shortened vacation
06:16 PM XXCoder: i have feeling I will get even more hours cuts
06:17 PM Tom_L: i'm wondering how many in the food etc industry won't reopen
06:17 PM XXCoder: mv1 at work ran out of work to do lol if that happens i know we are getting very serious work underflow
06:17 PM XXCoder: mv1 and mv2 is simply busiest machines at work
06:17 PM jthornton: yea I bet a lot of small mom and pop restaurants will just close the doors and walk away
06:18 PM Tom_L: yeah, the one that got layed off runs some large machines
06:18 PM jthornton: they still live at home?
06:18 PM Tom_L: jt, too bad too because those are the good ones
06:18 PM Tom_L: yes
06:18 PM XXCoder: do you know how hard it is to hire a machinist this state?
06:18 PM XXCoder: its why my job is almost unbreakable secure
06:19 PM Tom_L: XXCoder, abundance or lack of?
06:19 PM XXCoder: company is working really hard to retain all of us
06:19 PM Tom_L: i'd think there would be plenty out there
06:19 PM XXCoder: not this state apparently
06:19 PM XXCoder: we have been understaffed for years now due to this
06:20 PM jthornton: temperature is falling like a rock here
06:20 PM Tom_L: aparently they have trouble getting good help here too, that's why the company went to the vo'tech looking
06:20 PM jthornton: down 11°F in an hour
06:20 PM Tom_L: it was chilly here this am
06:20 PM Tom_L: wow
06:20 PM XXCoder: we desperarely need lathe machinists, that is, till recently. they have plenty of jobs to run tho compared to mills
06:20 PM Tom_L: keep it over there mkay?
06:21 PM Tom_L: XXCoder, their work has no lathes
06:21 PM Tom_L: my bud only had one
06:21 PM XXCoder: if we wasnt under hire freeze if you really know lathe machines your job'd be damn near unbreakable secure
06:21 PM jthornton: 35°F low tonight
06:21 PM XXCoder: 64f-47f here
06:21 PM Tom_L: i ran his okuma kadet for a while
06:22 PM jthornton: I don't find a CNC lathe much different than a VMC
06:22 PM Tom_L: i like the chips off mills better than lathes for sure
06:22 PM Tom_L: no not really
06:23 PM Tom_L: do you set soft limits on yours to avoid hitting the spindle etc?
06:25 PM jthornton: https://www.youtube.com/watch?v=G4-lUNa0CpY
06:25 PM jthornton: I should...
06:25 PM Tom_L: :)
06:26 PM jthornton: but different tool holder lengths makes that impractical
06:26 PM Tom_L: yeah you gotta be careful
06:27 PM jthornton: if I'm not super sure I dial down the rapids and test once
06:27 PM Tom_L: is that one on lcnc?
06:28 PM jthornton: yea, running Ubuntu 10.04 still
06:28 PM XXCoder: i never run new setup without walking in each tool and also option stop each tool
06:28 PM XXCoder: make sure its good then finally run a part
06:29 PM jthornton: yea I do a chicken check of tool position before running
06:29 PM jthornton: load the tool then mpg to what should be Z0 and check the DRO
06:29 PM XXCoder: one guy lathe machinist once got fired
06:29 PM Tom_L: i've gotten to trust my cad preview pretty much. probably about half and half will i run a test
06:29 PM XXCoder: because of not one or two impacts, but five of em
06:29 PM XXCoder: count em, 5.
06:30 PM jthornton: ouch
06:30 PM XXCoder: its that hard to fire a lathe machinist. he managed it tho
06:30 PM Tom_L: i did one side of the cube in a block of wood since i didn't wanna screw up his block
06:30 PM XXCoder: note its across few months
06:31 PM XXCoder: scrapped parts, and one machine had to be down in maintance (it was very busy time before everything we have issues now)
06:33 PM XXCoder: i wonder how hes doing now. been over a year ago now
06:33 PM jthornton: a guy that rides with us almost got fired from Boeing for not waiting for QC to check his setup
06:34 PM jthornton: that was back when everything was turret lathes and manual mills
06:34 PM Tom_L: that's about all they had at the place i ran the bar machines
06:34 PM XXCoder: heard boeing jobs is shit now
06:34 PM Tom_L: 3 rooms full of bar machines and a back room of turret lathes
06:35 PM Tom_L: or special machines
06:35 PM XXCoder: (ignoring covid and 737, this predates those)
06:35 PM Tom_L: i ran usually 4 bar machines 6 & 8 spindle
06:35 PM jthornton: he had $200 and caught a bus to St. Louis and got the job then 6 months later was drafted and went to Viet Nam
06:36 PM jthornton: filled the rear end of his beater with sawdust to sell it for $200
06:36 PM Tom_L: i found old 50 cal tooling down in the tool room one night
06:37 PM jthornton: cool
06:37 PM Tom_L: that was back when the women ran them
06:37 PM XXCoder: i dont know what to do still lol my orginial plan of working where I work at for 5 years then moving to boeing have been scrapped
06:39 PM jthornton: Rosie the riveter
06:40 PM XXCoder: yeah
06:40 PM Rab: jthornton, what does filling the rear end with sawdust do?
06:41 PM XXCoder: selling sawdust for $200 I guess
06:41 PM jthornton: women actually ran the uranium machine better than the scientists that built it
06:41 PM Rab: Ohhh, I thought it was a trick to sell the car.
06:41 PM jthornton: makes it run quiet
06:42 PM jthornton: quiets worn out gears
06:42 PM XXCoder: ah vibration damping lol
06:42 PM jthornton: yea
06:42 PM XXCoder: damn what a cheat
06:42 PM jthornton: back then you gotta do what you gotta do to survive
06:43 PM Rab: haha
06:44 PM jthornton: he didn't have any plumbing in the house he was raised on and by chance my Dad bought some of his parents property
06:44 PM jthornton: I built my Dad's house on that property
06:45 PM jthornton: his tires were so worn out he would stuff rags in under the inner tubes to keep them from poking out and getting a flat
06:46 PM jthornton: he said one time he had 3 flat tires trying to pick up a girl for a date
06:48 PM XXCoder: geez
06:49 PM Tom_L: did he have a dog named 'lucky' too?
06:49 PM jthornton: the guy I get rock from used to fill his truck from the creek with a shovel by hand
06:49 PM jthornton: no he had a goose named Boris
06:50 PM XXCoder: dog named lucky I picture one eyed 3 legged
06:50 PM jthornton: he found the same truck as his first one and restored it to original
06:50 PM jthornton: and no tail lol
06:51 PM XXCoder: yea
06:52 PM jthornton: chow time here
07:27 PM cgi: I am looking for a 24" x 24" x 72" shelve for storage - anyone knows where i can find a good one? or perhaps where to ask?
07:29 PM cgi: k - I found some, thanks
07:32 PM jdh: over there.
07:34 PM jymmmm: cgi: restaurant racks. rated at 1200lbs per shelf, 3000 lbs per rack, on floor, not casters
07:57 PM andypugh: Making a gear on a leadscrew: https://youtu.be/xdE46yvckbM
07:57 PM andypugh: (featuring a fat bloke with a lockdown haircut and beard)
08:13 PM skunkworks: I went the other way... I shaved my head.
08:14 PM XXCoder: i went middle way
08:14 PM XXCoder: hair is techinically still growing
08:14 PM XXCoder: but I look same since before lockdown
08:15 PM jymmmm: andypugh: Nice job
08:16 PM skunkworks: andypugh: does that get hardened?
08:16 PM XXCoder: cool video
08:17 PM XXCoder: is the 4th axis same one you was working on bit ago?'
08:17 PM Tom_L: sure a fast worker :)
08:17 PM andypugh: I don’t know. I will mention it to the recipient.
08:17 PM andypugh: It runs slow and slides about. Probably no need.
08:17 PM XXCoder: intersting that it can be converted to horzional mill
08:18 PM XXCoder: oh gear synced
08:22 PM Tom_L: how long was the actual cutting time? approx..
08:26 PM andypugh: 1.2 hours.
08:27 PM andypugh: But I didn’t need to be there.
08:27 PM Tom_L: that's not bad
08:27 PM andypugh: It could probably be done a lot faster.
08:28 PM andypugh: But I only had one blank, and it is quite long and thin.
09:15 PM JavaBean|new is now known as JavaBean
09:39 PM norias: hello
10:01 PM andypugh: hi
10:04 PM norias: how are you?
10:05 PM XXCoder: hey
10:10 PM norias: hi XXCoder
10:10 PM XXCoder: whats up
10:11 PM andypugh: I seem to be spending 3 weeks trying out retirement, but on full pay. So I am quite cheerful :-)
10:11 PM norias: deciding if i should stay up or not
10:11 PM norias: trying to get a little more involved in linuxcnc
10:11 PM norias: because i'm thinking about going to school for CS
10:12 PM norias: and, i'm a machinist
10:12 PM norias: so, seems like a good area in the venn diagram
10:15 PM andypugh: Can’t really advise, I am neither a machinist nor a CS. :-)
10:16 PM andypugh: But: I enjoy machining the parts I choose to make. I really can’t see long-term happiness in making parts to order.
10:16 PM norias: it's a good time, really.
10:16 PM norias: i do all prototyping, so it keeps it interesting
10:16 PM norias: but i enjoyed production, too
10:17 PM norias: it all has its challenges
10:17 PM andypugh: Whereas CS (if you are in the right bit of it) is always a new puzzle to solve.
10:17 PM XXCoder: andypugh: honestly youre more of a machinist than I am
10:17 PM norias: which is actually what is drawing me towards the CS
10:17 PM norias: because I feel like a lot of my machining challenges in the future will involve software
10:17 PM andypugh: The crossover is where the fun is.
10:19 PM andypugh: One night I couldn’t sleep, and my mind wandered and I thought “It would be really easy in LinuxCNC HAL to make a rotary axis run in synch with a spindle to hob gears”
10:19 PM andypugh: And, it turned out, it was.
10:19 PM norias: neat
10:19 PM XXCoder: it was lcnc sych and not gears?
10:19 PM XXCoder: nicely done
10:20 PM andypugh: I really don’t know if anyone had done that before me.
10:20 PM andypugh: Probably.
10:20 PM norias: i
10:20 PM norias: i've only seen stuff like that with specialized machines
10:20 PM norias: or some kind of mechanical attachment for a bridgeport
10:20 PM norias: usually shop made
10:21 PM norias: or especially on the old school horizontals
10:21 PM andypugh: But my video of it from 10 years ago has 200k views.
10:21 PM norias: nice
10:21 PM norias: i'm mostly interested in automation and optimization
10:21 PM andypugh: Yes, I moved on from my nasty mini-mill to an old-schoool horizontal, they suit the job.
10:22 PM norias: and they are cheap these days
10:23 PM andypugh: I wasn’t actually meaning to steer this to todays new video. But, it seems relevant. https://youtu.be/xdE46yvckbM
10:23 PM norias: hahaha
10:23 PM norias: plug, plug, plug
10:24 PM andypugh: That’s not something you can do with just machining, or with just a computer, it’s exactly in the are of the Venn diagram you are taling about.
10:24 PM andypugh: Tell you what, ignore my video.
10:24 PM andypugh: Here’s another.
10:25 PM andypugh: https://www.youtube.com/watch?v=C0Wz8vnFAQU
10:25 PM andypugh: Do that without both skill
10:25 PM XXCoder: its definitely cool
10:26 PM andypugh: skunkworks: Do you have a video of the spiral hole?
10:26 PM norias: nice
10:26 PM norias: you could _probably_ do that with just gcode
10:26 PM andypugh: Or just photos
10:26 PM norias: but it'd take some figuring
10:27 PM andypugh: norias: With a rotary axis perpendicular to XY, yes. But that has the XY slaved to spindle angle.
10:27 PM norias: i think you'd pull it off with just a three axis
10:27 PM norias: it's damn creative thinking
10:28 PM andypugh: I have a video of boring a hexagonal hole where I had to crank the spindle by hand to get it slow enouch for the axis.
10:28 PM andypugh: norias: In theory that gives perfect sharp corners.
10:28 PM norias: yeah
10:28 PM norias: ever see watts drills?
10:28 PM XXCoder: assuming infinite acceration I guess?
10:29 PM andypugh: Yes, I have seen the drills, and the rotary broaches.
10:29 PM andypugh: The drills you can at least align.
10:30 PM norias: yeah
10:30 PM XXCoder: we align broaches at work
10:30 PM norias: i think there's a way to align the rotary broaches
10:30 PM XXCoder: one has +- 1 degree requirement
10:30 PM XXCoder: we uses arm and posts on sides
10:30 PM norias: watts brother's (the makers of those drills) is within 45 minutes driving from me
10:30 PM XXCoder: posts can be moved forwards or back for aaltering angle, using dial indictor
10:30 PM andypugh: https://forum.linuxcnc.org/10-advanced-configuration/38549-non-circular-boring-linuxcnc-fun?start=30#162625
10:31 PM XXCoder: andy if you just use it for circle would it act as very precise borer?
10:31 PM XXCoder: like komit and such
10:31 PM andypugh: I don’t think you can drill or broach that. A broach with enough edge to lead couldn’t wobble.
10:32 PM andypugh: XXCoder: It’s a known thing.
10:32 PM andypugh: The big boys have demos.
10:32 PM XXCoder: fancy
10:32 PM andypugh: (for circular)
10:32 PM XXCoder: we just use komits at work
10:32 PM XXCoder: when needed anyway. depends on few factors
10:34 PM pcw_home: XXCoder: "assuming infinite acceration I guess?" Not if the spindle speed is modulated :-)
10:34 PM XXCoder: lol ok
10:34 PM XXCoder: not too sure what it means?
10:35 PM pcw_home: you could stop at the corners
10:35 PM _unreal_: pcw_home, tomorrow I'm going to a friends and we are going to finish building my motor controller box
10:35 PM _unreal_: will be nice
10:35 PM XXCoder: aha yeah
10:37 PM pcw_home: _unreal_ slow and careful on initial startup, that's often when things go awry...
10:47 PM norias: hi pcw_home
10:49 PM _unreal_: I'm refering to building the metal box to MOUNT the motor controller into
10:54 PM Tom_L: i thought he built that for you already
10:56 PM pcw_home: Hi norias, Im not long for this world, just ate 1/2 a a good size pizza and my eyes are hooding over...
10:56 PM norias: haha
10:57 PM norias: i just started listening to heavy metal
10:57 PM norias: and that woke me up
10:57 PM norias: Black Sabbath with Rob Halford on vocals
11:00 PM pcw_home: listening to a little Link Wray
11:05 PM norias: sounds fun
