12:00 AM evilroot: You just need four diodes that can handle the current
12:02 AM evilroot: And diodes even at that size are cheap
12:02 AM nullifier: Isn't that going to be super noisy
12:02 AM evilroot: AKA a bridge rectifier
12:02 AM MrHindsight: nullifier: what were they off of?
12:02 AM ve7it: ok... probably good for light engraving with a fast spindle... I would like a mid sized router table maybe 600x900mm working area
12:02 AM evilroot: nullifier: not terribly. Easily dealt with using an inline capacitor
12:02 AM nullifier: MrHindsight: NFC, some plasma table I think. They looked to be paired off, only two have terminators on the bottom.
12:02 AM ve7it: mostly for making custom kitchen cupboard doors
12:02 AM nullifier: $25 each, fleabay. Couldn't ignore price
12:02 AM MrHindsight: yeah
12:02 AM * evilroot is an electronics engineer
12:02 AM MrHindsight: EE
12:05 AM MrHindsight: or EEE
12:05 AM nullifier: I am studying mechanical design
12:05 AM evilroot: Evil Electronics Engineer
12:05 AM evilroot: EEE
12:05 AM nullifier: Eventually my goal will be attending MTU
12:05 AM nullifier: up here in Da Yoop
12:05 AM evilroot: Actually I'm lying, my degrees were dual Comp Sci and Comp Eng
12:05 AM nullifier: I have a comp-sci degree
12:05 AM evilroot: And I dropped out to start a business because I got really bored
12:05 AM nullifier: BA
12:05 AM nullifier: doesn't do shit-diddly-squat for me
12:05 AM evilroot: That's why I left, all by friends graduating lived in cubicles
12:05 AM nullifier: the classes don't have any bearing on reality either
12:05 AM evilroot: Exactly
12:05 AM nullifier: far too much time between 'this is now' and 'we wrote a book for you to learn stuff from'
12:05 AM evilroot: My professor in one class was going on about safety while I was playing Asteroids on the oscilloscope
12:05 AM nullifier: Ugh... safety.
12:05 AM evilroot: It blew his mind
12:05 AM nullifier: hell I have done that before, though I had no idea how it worked
12:05 AM nullifier: not asteroids, tetris
12:06 AM evilroot: It was an Easter Egg in certain TI scopes, haha
12:06 AM nullifier: Ah, yeah mine was a vector generation python script
12:06 AM evilroot: I was like really, you're going to waste two hours of my time talking about lab safety? We're only working with fucking 5 volts!
12:07 AM evilroot: What are you going to do, take out an eye with a soldering iron?!
12:07 AM nullifier: CYA on that one though. They didn't tell me! *paperclip in receptacle*
12:08 AM evilroot: Oh wow its on youtube
12:08 AM evilroot: https://www.youtube.com/watch?v=pWozXyGfKjg
12:08 AM nullifier: I have it the opposite way where I'm taking classes. They put us in front of a 32 year old mill run by 7mhz Fanuc PLCs.
12:08 AM nullifier: No manual. No safety glasses
12:08 AM nullifier: 'make me a circle'
12:08 AM nullifier: Didn't even bother explaining the chuck
12:09 AM evilroot: Where are you?
12:09 AM nullifier: I took over immediately. NFW these kids are going to snap tools while I'm watching
12:09 AM nullifier: Ironwood, MI
12:09 AM evilroot: What kind of school?
12:09 AM nullifier: Community college w/ a program designed in 1975
12:10 AM evilroot: Dude, you're getting the real deal
12:10 AM nullifier: I would be, but the teacher who taught it 'real' is gone. :(
12:10 AM evilroot: I thought I was getting the best going to NC State with a scholarship
12:10 AM evilroot: Instead they taught us Java and the electronics lab was a joke
12:11 AM nullifier: Ew.
12:11 AM nullifier: Tech school should be ad-hock
12:11 AM nullifier: like IT certs
12:11 AM evilroot: I mean this is one of the better engineering universities in the country
12:11 AM nullifier: "I can solder!"
12:11 AM nullifier: "I can *wave* solder"
12:11 AM evilroot: Not a CC, an actual public university with $30k+ tution
12:11 AM nullifier: Boy... talk about different
12:12 AM nullifier: yeah so is MTU
12:12 AM evilroot: I was also admitted to MIT and CalTech
12:12 AM evilroot: But NCSU gave me a free ride
12:12 AM nullifier: heh... you know what I find hilarious
12:13 AM nullifier: there's a guy in my class who was homeless last year, and started school. He gets 30% more financial aid than I do, and I'm a vet.
12:13 AM nullifier: lesson in that is, don't sign up for a bullet when you can just be a wino for a few years.
12:13 AM evilroot: Thanks for your service
12:14 AM nullifier: np, it was some of the best learning and times I've ever had
12:14 AM evilroot: Almost went in myself
12:14 AM nullifier: they don't fuck around
12:14 AM evilroot: In hindsight I wish I did
12:15 AM evilroot: Got a 99.8% on the ASVAP
12:15 AM evilroot: Recruiter told me pick whatever I wanted
12:15 AM nullifier: HUMINT
12:15 AM evilroot: But my Mom hated the military, talked me out of it
12:15 AM nullifier: best sector of defense
12:16 AM XXCoder: nullifier: yeah from what I see so far, all VAs get screwed over
12:16 AM evilroot: Nah, I would have worked on avionincs
12:16 AM evilroot: I'm an expert soldering tech
12:16 AM nullifier: I have 3 classmates who are avionics techs
12:16 AM evilroot: And I speak fluent Japanese, so guess where they would ahve put me
12:16 AM nullifier: radio room
12:17 AM XXCoder: office job where you never meet anyone else
12:17 AM nullifier: or with cans on in a boat in the middle of the sea of bahrain
12:17 AM evilroot: They offered me a full college degree and a rank of Captain
12:17 AM nullifier: which is one of the 3 things I did
12:17 AM evilroot: (In the Air Force)
12:17 AM nullifier: 94X - farsi translator
12:17 AM nullifier: Do I remember any farsi? Nope!
12:18 AM evilroot: sobh be kheyr!
12:18 AM nullifier: then I did 52D-C9, power generation systems repair, patriot missle systems
12:18 AM XXCoder: if I ever get drafted, I would cry for usa
12:18 AM nullifier: and that one came w/ 13M, heavy truck
12:19 AM XXCoder: because shit got so bad they had to reach all way down to me
12:19 AM evilroot: Recognize that one?
12:19 AM nullifier: evilroot: I probably should, but no. I think I had a stroke and it went kaput.
12:19 AM evilroot: Prob not spelled right, but then farsi has a different alphabet
12:19 AM nullifier: I'm only partially joking because seriously I remember almost nothing from that training
12:20 AM evilroot: One of the few I learned from my old business partner
12:20 AM nullifier: I couldn't even tell you what the name of the girl was I was doinking in Ft. Huachuca
12:20 AM evilroot: Who I like to call the Arab James Bond
12:20 AM nullifier: lol
12:20 AM evilroot: Talk about a crazy guy
12:21 AM evilroot: When we first became friends he had a check cashing place and I repaired electronics
12:21 AM evilroot: He was older than me. Brought me broken electronics. I fixed them
12:22 AM nullifier: Ah... ha. I think I just found a clue
12:22 AM nullifier: the Brother TC229 uses these amps
12:22 AM XXCoder: heh funny how life changes eh evilroot
12:23 AM nullifier: http://www.sanyodenki.biz/products/INSTRUCTIONMANUAL/ACservo/Ramp/GA1060/GA1060B_Manual_E.pdf
12:23 AM evilroot: We became friends. He was divorced, had married and American black woman and then she took everything from him in the seperation
12:23 AM nullifier: Here is the interface chip
12:23 AM nullifier: I see a CTX/CRX
12:23 AM evilroot: Didnt leave him a chair to sit on
12:23 AM evilroot: We ended up being friends. I learned a lot about Muslims I had never known
12:24 AM evilroot: And then learned he had been Syrian Military Police. And Special Forces
12:24 AM evilroot: But hated the guy in charge since he came here in the 90's
12:25 AM evilroot: That crazy MF then flew to Turkey, swam across the border, and extracted his now WIFE from the country
12:26 AM evilroot: Despite being on a list of people that should be shot on sight if they were ever caught in Syria
12:26 AM evilroot: That's BALLS
12:26 AM evilroot: That was 5 years ago
12:27 AM evilroot: Now his wife speaks decent English (he is so fluent you would never know its his 5th language)
12:27 AM evilroot: And his daughter is 4 and loves me, and his son is 1
12:28 AM XXCoder: dang
12:28 AM evilroot: He's 47 and she is 29
12:28 AM evilroot: Younger than me
12:29 AM XXCoder: my parents had larger age difference
12:29 AM evilroot: But looking at him you would think he's 30
12:30 AM evilroot: He's just such a picture of health
12:30 AM evilroot: Guess that's what never drinking does, heh
12:30 AM nullifier: hmmm
12:30 AM XXCoder: probably not smoking either, that ages skin pretty fast
12:30 AM nullifier: wondering if my buspirate would be safe to solder up to that bastard
12:30 AM XXCoder: my mom looks 80
12:30 AM XXCoder: shes 69
12:31 AM evilroot: He did smoke, but then turned to vape
12:31 AM evilroot: His wife made him, heh
12:31 AM XXCoder: lol
12:31 AM evilroot: People think than Muslim men rule over their wives and control them
12:31 AM XXCoder: some do. but then some christian men does also
12:31 AM evilroot: But she has him so wound around her finger its hilarious
12:32 AM evilroot: He will bend over backward to make her happy
12:33 AM evilroot: When we had the store our landlord was a big Trump type Republican
12:33 AM evilroot: And asked him if he "made" his wife wear a burkha
12:34 AM evilroot: And he said no, actually I told her not to!
12:34 AM * XXCoder facepalms
12:34 AM XXCoder: I wonder what that landlord thinks of trump now
12:34 AM evilroot: Hw worried it might make her a target. Her own family told her not to
12:35 AM evilroot: But SHE wanted to
12:35 AM evilroot: She said that the only person she wanted to see all of her was her husband
12:36 AM XXCoder: thats cool
12:36 AM XXCoder: I hate burkha but really if she truly wants to im ok with it
12:36 AM evilroot: That landlord actually asked me. He asked me if I could explain it
12:38 AM evilroot: I tried but really couldn't and so my business partner and he (and he was a hardcore Southern Baptist) talked to a Muslim man and they got along
12:40 AM XXCoder: I guess it just wasn't in his reality map
12:43 AM XXCoder: glad it worked out
01:28 AM MrHindsight: http://www.3ders.org/images2017/silicon-valley-tytus3d-launches-sub-300k-metal-3d-printer-rival-eos-slm-solutions-3.jpg
01:28 AM MrHindsight: wow and easy to use GUI for SLS printing?
01:28 AM MrHindsight: and/an
01:28 AM nullifier: How much?
01:29 AM MrHindsight: the printer is $300k
01:29 AM XXCoder: cheap at $50,000
01:29 AM MrHindsight: http://www.3ders.org/articles/20171006-silicon-valleys-tytus3d-launches-sub-300k-metal-3d-printer-to-rival-eos-slm-solutions.html
01:29 AM XXCoder: lol I didnt go far enough with joke :P
01:29 AM MrHindsight: with 500-watt laser
01:30 AM MrHindsight: intuitive GUI ??
01:30 AM nullifier: speaking of lasers
01:31 AM nullifier: if you unfocus a diode laser, does it heat at all
01:31 AM MrHindsight: the energy is still there, just over a greater area
01:32 AM nullifier: I just remember something about beam coherence
01:32 AM MrHindsight: joules per sq mm
01:32 AM nullifier: hmm.
01:33 AM nullifier: Just wondering how well a laser heated dab rig might sell
01:33 AM nullifier: there are so many crazy contraptions but I have yet to see a laser
01:34 AM MrHindsight: class IV laser needs lotsa safety stuff
01:34 AM nullifier: it would be enclosed
01:34 AM MrHindsight: ^^ actual technical terms
01:35 AM nullifier: There's people spending $600-1500 for a rig
01:35 AM MrHindsight: https://www.youtube.com/watch?v=uolPCIBgGOw wow what an accent!
01:35 AM nullifier: for a nichrome heater
01:35 AM MrHindsight: Coherence in Laser
01:36 AM IchGucksLive: hi all from a nice germany
01:37 AM XXCoder: hey from dark tacoma
01:37 AM nullifier: hey from frozen upper peninsula
01:38 AM nullifier: I can totally see this working really well just heating some mica sheet
01:38 AM MrHindsight: nullifier: anywhere near Lake Michigamme?
01:39 AM nullifier: Gamme? No. That's downstate, where der trolls live.
01:39 AM nullifier: oh wait I am wrong
01:39 AM nullifier: yes, near marquette
01:40 AM MrHindsight: https://www.google.com/maps/@46.5151368,-88.0754306,12z
01:40 AM nullifier: Yeah we call that Three Lakes around here
01:41 AM nullifier: I am https://www.google.com/maps/place/Ironwood,+MI+49938/@46.4486977,-90.1713085,14z
01:41 AM nullifier: We have a 50ft statue of Hiawatha, made of resin fiberglass
01:42 AM MrHindsight: not far from Lac Du Flambeu
01:42 AM nullifier: Nope. Go there regular for der bingo.
01:42 AM nullifier: Thursdays
01:43 AM MrHindsight: we used to fish and stay up in those areas
01:43 AM nullifier: C'mon back. Buy some property.
01:43 AM nullifier: You'll lose your shit when you look at some of the prices for housing here
01:43 AM MrHindsight: ais it part of Cansda yet? :)
01:43 AM MrHindsight: Canada even
01:44 AM nullifier: I wish. By dialect, yep.
01:44 AM MrHindsight: and about as cold as Frostbite Falls
01:44 AM nullifier: -26F lows in January
01:45 AM MrHindsight: we get near there
01:45 AM nullifier: ~300" of snow, though it's been less
01:45 AM MrHindsight: but less snow
01:45 AM nullifier: mostly lake effect. World record totals.
01:45 AM MrHindsight: used to ski up there as well
01:45 AM XXCoder: hmm
01:45 AM XXCoder: I wonder what camera system is best for home
01:45 AM XXCoder: just want to cover front and side doors
01:46 AM nullifier: There's a 720P Qing camera on alibaba right now, TI omap chip, G wireless. $8
01:46 AM MrHindsight: oh you're right by Big Powderhorn
01:46 AM MrHindsight: a friend had a cabin on the resort
01:46 AM nullifier: Yep, in fact I have a parcel up there.
01:47 AM nullifier: Burned cabin. Has water and electric.
01:47 AM nullifier: Cost?
01:47 AM nullifier: Get ready...
01:47 AM nullifier: $6
01:47 AM XXCoder: nullifier: got link?
01:47 AM MrHindsight: how much for the legal fees?
01:48 AM nullifier: it's on the main page, if I link it to you it will just send you back to the main page lol
01:48 AM nullifier: Taxes were in arrears to $6k, were waived.
01:48 AM XXCoder: aliexpress?
01:48 AM nullifier: You can look there... I mean honestly you're looking for what looks like a dropcam
01:49 AM nullifier: they're all the same, Hikvision, Dahua, wtf ever. Acceptable
01:52 AM XXCoder: AHD camera "HOT SALING!"
01:53 AM MrHindsight: oh nooes! https://www.youtube.com/watch?v=Po-t5LZgWcE Big Powderhorn Mountain Lodge Fire
01:54 AM nullifier: https://www.aliexpress.com/store/2230079
01:54 AM nullifier: yeah that was a long time ago now
01:54 AM nullifier: it hasn't recovered
01:55 AM nullifier: the area has lost about 80% of the tourism it once saw
01:55 AM MrHindsight: are the lifts still open?
02:11 AM IchGucksLive: morning gloops
02:11 AM gloops: hi Ichs
02:17 AM RyanS: du hast mich (thats not a relevant greeting , just the first German phrase i could think of)
02:17 AM RyanS: or achtung
02:18 AM IchGucksLive: RyanS: no
02:18 AM IchGucksLive: RyanS: you are great
02:18 AM IchGucksLive: as you think big
02:19 AM IchGucksLive: i got so lo budget
02:19 AM RyanS: or schnell
02:20 AM RyanS: i want to schnell with my plasma table
02:22 AM IchGucksLive: Then go chewep and fast
02:22 AM XXCoder: nullifier: https://www.amazon.com/ELEC-Security-Weatherproof-Surveillance-Detection/dp/B01N5OVTG7/
02:22 AM IchGucksLive: with AL-Profile UCP TR and a Stepperet
02:22 AM IchGucksLive: RyanS: 4hr to Plasma
02:23 AM IchGucksLive: With a friend
02:23 AM IchGucksLive: RyanS: the 4Axis i gave you as a construction is that
02:24 AM IchGucksLive: RyanS: also with HIWIN on 250 more
02:24 AM RyanS: oh, yes, i need to download the viewer!
02:24 AM RyanS: guten morgen
02:24 AM IchGucksLive: Rx my best is that i got this supplöyer on direct hand http://www.cnc-discount.de/
02:25 AM IchGucksLive: RyanS: yoiu are to solw on monitoring ((ZU LANGSAM)
02:26 AM Deejay: moin
02:26 AM IchGucksLive: RyanS: and for me as a top buyer he organises also 3meter long at 5days delevering
02:26 AM IchGucksLive: de guten Morgen
02:26 AM IchGucksLive: Deejay: is ther sommer around you
02:27 AM Deejay: yeah, i like it
02:27 AM RyanS: Ich werde mich beeilen (thanks google)
02:29 AM IchGucksLive: RyanS: i will send you the full rack pinion step
02:29 AM gloops: whats the cycle with these plasmas anyway, i mean its ok moving the head like lightning, how long can it cut for?
02:30 AM RyanS: depend on duty cycle
02:30 AM gloops: youll need a 2k plasma to keep that up
02:31 AM RyanS: i have a 5k au plasma, does that count
02:32 AM gloops: i see, well no need to brag about it haha
02:33 AM RyanS: its more like 'that was a painful purchase '
02:34 AM gloops: myself, i would throw everything into the biggest most accurate machine you can house
02:34 AM gloops: you would have the ability for contract work there big$$
02:35 AM archivist: the really painful part is dealing with customers
02:35 AM gloops: yes correct archivist
02:35 AM RyanS: 1200x1200 is the biggest
02:35 AM gloops: ive been in services for 30 years, totally had enough
02:35 AM RyanS: customers, arggghh!
02:36 AM archivist: I just sacked a customer
02:36 AM gloops: thankfully most cutting work can be arranged online
02:36 AM gloops: fax the diagram, email price back
02:37 AM XXCoder: archivist: why?
02:39 AM gloops: phonecalls, at all hours, people turning up at the door, some real weirdos, its a pain in the ass, depressing often
02:39 AM RyanS: Willst du Strudel nach deinem Bier und Schnitzel
02:40 AM IchGucksLive: beer
02:40 AM the_wench: I am not your waitress!
02:40 AM gloops: you look at these salesmen - they take them into a room every morning and give them evangelical prep talks, boosting their egos - you need it to face joe public all the time
02:41 AM XXCoder: the_wench: ice water please
02:41 AM RyanS: i will keep my phone number secret lol
02:41 AM gloops: ive got 3 phones
02:42 AM RyanS: Mein Schäferhund aß mein Schnitzel
02:43 AM archivist: XXCoder, rudeness
02:43 AM XXCoder: some customers do think workers is less than human
02:43 AM XXCoder: http://notalwaysright.com/
02:43 AM IchGucksLive: RyanS: mail
02:44 AM IchGucksLive: gloops: i got non
02:44 AM gloops: best way to be Ichs
02:44 AM IchGucksLive: im off work so mail me no more hurry
02:44 AM IchGucksLive: time is a real gift
02:44 AM RyanS: IchGucksLive got it
02:45 AM RyanS: Auf Wiedersehen
02:54 AM gloops: http://www.ebay.co.uk/itm/SBR16-300-1350-1350MM3-SETS-LINEAR-RAILS-3-SETS-BALL-SCREWS-BALLSCREW-RM1605/311367687009?
02:54 AM gloops: i got some of that kit, 200 quid, youre set for 1200x1200
02:58 AM IchGucksLive: gloops: is a plasma so it is what he needs
03:01 AM IchGucksLive: gloops: he can connect without endmiling
03:01 AM IchGucksLive: you go via UCP bearing
03:01 AM IchGucksLive: and via timingbelt hole drill to the ballscrews
03:02 AM gloops: could makes some sleeves for the ends also, i dunno my own limited experiences tells me theres an easy way to get accuracy and speed, and there are hard ways, these kits you get more for the same money than if you buy individual parts, everything there to build not waiting for one item for weeks
03:04 AM IchGucksLive: yes and wiith standard AL-profile parts you are up in one day with the whole mashine
03:04 AM IchGucksLive: gloops: my 4axis is that way
03:05 AM RyanS: ditch the hiwins?
03:05 AM IchGucksLive: the sbr can be tight to the Profile by Sheet screws
03:05 AM IchGucksLive: RyanS: its a price
03:05 AM RyanS: ?
03:06 AM IchGucksLive: RyanS: speed,Force is HIWIN
03:06 AM RyanS: high price?
03:06 AM gloops: those bearings i made work fine, can vouch for those, just a bigger section of tube with some flat bar tacked on, bearing every end - you wont bother those with dust and smoke
03:06 AM IchGucksLive: SBR is a limit
03:06 AM gloops: like a roller coaster
03:07 AM IchGucksLive: RyanS: that set will give you a mashine fast and workable
03:07 AM IchGucksLive: RyanS: but not on your expected numbers
03:08 AM RyanS: but will round rails allow the machine to moonlight at a wood router?
03:09 AM gloops: sbr - they all used them before the square rails came out
03:09 AM IchGucksLive: RyanS: http://heimwerkermarkt-tretter.de/holzcnc.jpg
03:09 AM IchGucksLive: RyanS: this mashine is build only with a ACCUdrill
03:10 AM XXCoder: not bad
03:10 AM IchGucksLive: Standard wood spacks
03:10 AM XXCoder: I'm unsure what to do with my set of ballscrews and sbr set
03:10 AM gloops: there was someone building a 3 metre plasma on facebook but the photos are long gone, he used 25mm ballscrew and rails, but he located everything out of the blast of the cutting
03:10 AM XXCoder: I already have cnc router so yeah
03:11 AM IchGucksLive: gloops: sheets are 2500x1500
03:11 AM IchGucksLive: we got also a 3meter
03:11 AM IchGucksLive: but on gantry rack pinion
03:11 AM nullifier: I made bellows for my router out of old window blinds
03:11 AM IchGucksLive: with high precion GEAR
03:12 AM IchGucksLive: 30:1
03:12 AM IchGucksLive: 200Euros eatch
03:12 AM nullifier: ?!
03:12 AM nullifier: rack & pinion 30:1?
03:13 AM IchGucksLive: max dialer read out at 4hr non plasma run at real sped part has been 0,2mm offset
03:14 AM IchGucksLive: nullifier: Motor 400steps * 30 = 12000 steps Mashine Pinion T10 Rack Z12 =120mmU precision 0,01 makes 120000 SMILE
03:14 AM RyanS: https://www.youtube.com/watch?v=vxAsO9YZNYM how about these v-rail, integrated rack? id make the carriage , buy rail and rollers
03:15 AM nullifier: I'd sooner use a linear motor
03:17 AM gloops: looks like a load of messing about tbh to make them
03:18 AM RyanS: IchGucksLive: why not use 5:1 belt reduction , higher microstepping? i understand you loose torque, but bigger steppers are cheaper than Au$400 30;1 gearbox
03:20 AM XXCoder: from what I understand ratio adds backlash but that may be gears only
03:20 AM RyanS: gloops its just a plate, mill square, DRO to locate holes
03:21 AM IchGucksLive: RyanS: bigger stepeprs More Amps at loing Lines
03:22 AM IchGucksLive: RyanS: Even at 72Volt
03:22 AM IchGucksLive: im off later
03:24 AM RyanS: hmm dm556 (5.6A, 50V) = $67au, dm856 = $71
03:24 AM RyanS: dm856 8A, 80B
03:25 AM RyanS: v*
03:27 AM archivist: choices and compromises
03:31 AM MarcelineVQ: If I buy a china vfd that says 220v am I going to be able to use it with my north american 220v that is actually two opposite phase 110v?
03:32 AM MarcelineVQ: I realise that's not answersable with complete certaintany but I'm asking in case anyone has experience with it
03:33 AM XXCoder: bunch of vfd can run on either 110v or 220v and has switch on psu
03:33 AM XXCoder: but yours specifically is unknown
03:35 AM XXCoder: btw that was nonauthorial answer, dont buy based on that answer
03:36 AM MarcelineVQ: I don't want a 110v connection though, it's just that 220v here it accomplished by the voltage potential between two 180 degree phased 110v connections. I guess I'd like to know if I can make that hook up in the general case. maybe jthornton or evilroot would know, I'll have to ask again later
03:36 AM XXCoder: yeah
03:36 AM XXCoder: jt should be here in 3 to 4 hours
03:36 AM archivist: MarcelineVQ, I would think so
03:37 AM gloops: Ryan its 2 for X then some for Y
03:37 AM MarcelineVQ: I should look up how europe's 220v works and then work backwards from there
03:37 AM archivist: just the two wires
03:37 AM archivist: one is known as neutral the other live
03:38 AM MarcelineVQ: live and neutral?
03:38 AM MarcelineVQ: ye
03:39 AM archivist: the VFD should state input range and frequency yours is 60hz
03:44 AM RyanS: speaking of power, are UK industrial sockets the same as? https://www.sparkydirect.com.au/p/932056/pulset---4-pin-50amp-combination-switched-socket---ip66-rated-ipco3ph450.html
03:47 AM RyanS: the 3pin industrial plugs are only available in 32A, my plasma unit needs single phase 45A
03:56 AM MarcelineVQ: there's quite a variety of plugs here, industrial and non, for 220. with a few being 50 amp 3 pins, are you sure you can't find 50A where you are? that site might just not have them
04:00 AM RyanS: everthing needs to adhere to electrical code, only australian standards 3pin are 10A, 15A, 20A, 32A
04:01 AM RyanS: any higher is 3phase
04:06 AM RyanS: i have no idea if these conform to Australian standards for domestic power http://au.rs-online.com/web/p/industrial-power-connectors/8305186/
04:07 AM MarcelineVQ: At that point I'd be asking an electrician, domestic power will have the issues of wire and breaker size in the walls to be conerned about with high amp load
04:10 AM RyanS: yeah , we're putting 50A wire in , mounting sockets, getting electrician to install breaker & check
04:11 AM RyanS: some new houses have 3phase :-(
04:11 AM MarcelineVQ: Awesome that'd be a good time to ask him how you'd get your plasma hooked up, if you've not solved your plug issues by then
04:50 AM jthornton: morning
04:50 AM XXCoder: hey jt
04:51 AM XXCoder: guy here was wondering if euro 220v would work on usa 220c
04:51 AM XXCoder: 200c
04:51 AM jthornton: the DS3231 failed yesterday so I'm back to a timer for the chicken door
04:51 AM XXCoder: dammit 220v
04:51 AM jthornton: euro is 50hz we are 60hz so maybe it will maybe it won't
04:52 AM XXCoder: interesting
04:52 AM RyanS: cockadoodledo
04:52 AM XXCoder: can always buy convertor
04:52 AM RyanS: o
04:52 AM XXCoder: I did for that crappy "router" lol I recently got rid of em
04:54 AM jthornton: so I'm going to try a Blueberry Pie next to control the door
04:55 AM XXCoder: then orange pi? ;)
04:55 AM XXCoder: as well as try all fruits
04:55 AM jthornton: lol
04:56 AM XXCoder: :)
04:58 AM XXCoder: holy crap. https://notalwaysright.com/time-give-space/97210/
05:01 AM jthornton: hey got a free haircut from the aggravation
05:02 AM MarcelineVQ: jthornton: I was actualy wondering if a china vfd that says 220v on it can be connected to the american version of 220v
05:02 AM jthornton: I'm sure it can, most VFD's are made in china
05:02 AM MarcelineVQ: which is to say two lives and a neutral and/or ground
05:02 AM archivist: MarcelineVQ, the input mains is a different frequency, else yes
05:03 AM MarcelineVQ: The searching I've been doing since asking that also is leaning towards a yes
05:03 AM jthornton: ah yea another gotcha hot to ground 240 or 120
05:05 AM MarcelineVQ: hot to neutral is 120 in my case, 240 potential between hots because they're 180 degrees out of phase
05:07 AM jthornton: https://cdn.shopify.com/s/files/1/1098/4826/files/comparisonupdate.png?13077955502273113275
05:07 AM MarcelineVQ: I've a north america dryer plug setup here, nema 14-30 plug
05:07 AM jthornton: so many choices lol
05:08 AM XXCoder: MarcelineVQ: can always buy usa to euro power
05:08 AM XXCoder: I did
05:08 AM XXCoder: buy one rated few hundred watts higher than what your vfd
05:08 AM jthornton: what does that do?
05:09 AM XXCoder: convert 110v to 220v
05:09 AM nullifier: How do I get 2 rails and 4 carriages to not over-constrain an axis?
05:09 AM nullifier: is there some special trick to tramming
05:10 AM nullifier: or is it just 'hope' and a BFH
05:10 AM archivist: careful tightening sequence
05:11 AM jthornton: it helps to have square to the machine hard stops during assembly
05:11 AM nullifier: I feel like I am going to have to lay the whole gantry down flat in order to get it to not do this shhhhhhhhhhITE
05:11 AM archivist: two of the four at one end, tighten rails and carriages at left, move to right tighten rail right, then left again then tighten last two carriages
05:11 AM nullifier: lesson learned, do not take rails off... ever.
05:12 AM archivist: all depends on your machine design too
05:13 AM nullifier: I think the beams may have been prestressed
05:13 AM XXCoder: https://www.krackattacks.com/
05:13 AM nullifier: and I let go some bend it had when I took off the rail
05:13 AM XXCoder: wpa2 is kinda broken :(
05:13 AM XXCoder: replay attack on nonce
05:14 AM archivist: rail makers expect the frame and assembler to remove any bend
05:15 AM XXCoder: MarcelineVQ: https://www.amazon.com/Step-Up-Voltage-Converter-Transformer-Travel/dp/B00PVV2880 tiny example, only 100w version but yeah
05:18 AM MarcelineVQ: Thank you, that will affect the amp range I'm working with so I'd like to avoid it if possible but I'll keep the option open
05:19 AM XXCoder: yeah it definitely would lose some power
05:20 AM nullifier: https://github.com/vanhoefm/blackhat17-pocs
05:20 AM nullifier: Is actually old
05:20 AM * nullifier was there
06:29 AM jelly-home is now known as jelly
06:34 AM Tom_itx: jthornton, pi seems like alot for a chicken door..
06:34 AM Tom_itx: what about an avr with a rtc.ish inside?
06:34 AM jthornton: it does except for I can program it in python and ssh into it
06:35 AM Tom_itx: 128 supports a clock crystal
06:35 AM Tom_itx: i'm sure others do, i just knew that one did
06:39 AM jthornton: besides why should Gene have all the fun playing with raspberries
06:41 AM jthornton: the esp8266 would be fine I think as I can poll nst time each night
07:19 AM Loetmichel: Hmmm... doesnt look toooo bad... -> http://www.cyrom.org/palbum/main.php?g2_itemId=16821
07:19 AM Loetmichel: ... until the paint is sanded off... :-( -> http://www.cyrom.org/palbum/main.php?g2_itemId=16824
07:32 AM jthornton: my truck is named Rusty]
07:36 AM jthornton: damn door opened this morning but the light didn't come on :(
08:07 AM archivist: jthornton, are you blaming the wrong part?
08:16 AM jthornton: I rebooted the ardweeny and the light came on so not consistently wrong enough to blame the programmer at this point
08:18 AM archivist: JT is it just the drive switching voltage arguino pin to lamp driver/switch
08:19 AM archivist: threshold voltage/current
08:20 AM jthornton: what I have for now is a relay that is controlled by a timer, the relay is connected to an input that triggers the door to come up and the light to come on via some relays connected to output pins
08:20 AM jthornton: shower time here
08:20 AM jthornton: nice 6C outside and sunny
08:21 AM archivist: if one part works and another does not, that is the fault finding clue,
08:41 AM JT-Shop: yep
09:20 AM Simoniou1 is now known as Simonious
11:51 AM IchGucksLive: hi all from a real sunny germany on oktober the 16th
11:57 AM Loetmichel: maaan, i am getting old. just a bit of sanding, rust removal, sanding, rust converter, sanding, applying painters tape, painting with rust preventer paint, removing of tape, driving home and i am already out of breath... Tomorrow will see a light sanding again, then a few times filler, sanding filler, sanding until all rust pitting disappears, then "cosmos black metallic", 600 grit sanding,
11:57 AM Loetmichel: 2 times clearcoat... that part of the car will look better than all the rest of that rust bucket ;) -> http://www.cyrom.org/palbum/main.php?g2_itemId=16821&g2_imageViewsIndex=1 http://www.cyrom.org/palbum/main.php?g2_itemId=16827&g2_imageViewsIndex=1 http://www.cyrom.org/palbum/main.php?g2_itemId=16830&g2_imageViewsIndex=1
12:04 PM IchGucksLive: Loetmichel: youshoudt better do car repair then etech
12:05 PM Loetmichel: nah, way to much work. nice for a hobby, but every day? no thanks.
12:06 PM hazzy: Loetmichel: I would have left it at the red primer and called it a day :)
12:07 PM hazzy: Looks good!
12:07 PM Loetmichel: thats not primer. thats a rust preventer paint
12:07 PM Loetmichel: tomorrow it will see a few layers of filler/primer
12:08 PM Loetmichel: and THEN the final paint and clear coat... depending on my willingness to spend time after hours at the company to do the work there ;)
12:17 PM MrHindsight: https://imagebin.ca/v/3e09Lzm36aoF I cut all the rust out and replace with new metal
12:23 PM MrHindsight: https://imagebin.ca/v/3e0BG0urLqdK TIG in the new, grind, sand, avoid any filler..
12:32 PM IchGucksLive: amsR: Hi to india
12:32 PM IchGucksLive: if you need Help in mumbai just ask
12:34 PM amsR: @IchGucksLive: Thanks for your support, I'll definitely ping.
12:34 PM IchGucksLive: here are some helping tutorials to get startet https://www.youtube.com/channel/UCmwhCL92ZQRSVqFe3jGwJSQ/videos
12:35 PM IchGucksLive: amsR: its my channel
12:35 PM IchGucksLive: amsR: what mashine are you working on
12:44 PM IchGucksLive: hi Todd_Z
12:45 PM Todd_Z: hi
12:45 PM IchGucksLive: are the soja beans harvested
12:46 PM IchGucksLive: Todd_Z: ohio or
12:48 PM IchGucksLive: Todd_Z: the harvesters are build here in my town in germany
12:49 PM Todd_Z: Some fields have been cut, but most are still standing.
12:50 PM IchGucksLive: if i ride to the university i see the ones that been shipt over
12:52 PM IchGucksLive: Todd_Z: -> image of the place they stand http://www.agrartechnik-im-einsatz.de/de/index.php?page=view_picture&id=210527#anker
12:54 PM Todd_Z: a lot of money setting in that parking lot.
12:54 PM IchGucksLive: its only one of 4
12:54 PM IchGucksLive: as east and asia got there own and south/africa also
12:55 PM IchGucksLive: Todd_Z: the factory is able to output 20 of this per day
12:56 PM IchGucksLive: hi gloops
12:56 PM IchGucksLive: Todd_Z: as you may know if you nee help on cnc just ask
12:57 PM gloops: evening Ichs
12:57 PM IchGucksLive: ;-=
12:57 PM IchGucksLive: :p
12:57 PM gloops: eerie day in england today, red sun, strange skies
12:57 PM IchGucksLive: gloops: the chili is cooking in the backyard
12:58 PM IchGucksLive: gloops: orphilia did hit ireland hard
12:58 PM gloops: chili - grown them yourself Ichs?
12:58 PM IchGucksLive: but we got the bright sunshine here in germany
12:58 PM gloops: yeah very windy now
12:58 PM IchGucksLive: gloops: yes
12:58 PM IchGucksLive: and the peppers karots tomatos but no beans
12:59 PM IchGucksLive: and today i kow the cow personly the mead is from
12:59 PM gloops: i grew 1 chili plant - variety called Apache F1, about hundred chilis on it, small but pretty hot
12:59 PM IchGucksLive: ofcause one of 230+
01:00 PM IchGucksLive: gloops: this has been a good growing year
01:00 PM gloops: yeah been good for some things
01:00 PM IchGucksLive: we harvested 16000 tonns of corn for bio energie
01:01 PM gloops: need a good year for sweetcorn as well
01:01 PM IchGucksLive: never planted one
01:01 PM IchGucksLive: germans as special my age dont like corn products
01:01 PM IchGucksLive: as from WW2
01:02 PM gloops: we always grow about 20 plants, some years they do well, others not
01:03 PM IchGucksLive: isent it as normal corn you need at least 7 rows of 10 plants
01:03 PM IchGucksLive: as they do like to stuck eatchother
01:04 PM gloops: yeah they are wind pollinated - grow in blocks not rows
01:04 PM gloops: 5x4 works ok
01:05 PM IchGucksLive: feed spacing
01:05 PM gloops: cant grow 2 different varieties - one of the few plants if cross pollinated the flavour is ruined
01:06 PM IchGucksLive: we planted 8rows by 8rows different
01:06 PM IchGucksLive: also the 4/4 worked out good on mexican F1
01:08 PM IchGucksLive: Folkes good news just in im now 2more Grandpa
01:08 PM gloops: lol, congratulations
01:09 PM IchGucksLive: need to close maybe we go to hospital
01:09 PM IchGucksLive: Grandma is happy
01:25 PM MrHindsight: funny how these ChinaCo routers mix SS with red oxide fasteners
01:32 PM gloops: haha theyre mainly the sweepings up
01:34 PM MrHindsight: the base and gantry use SS, all the motors, cable holders, etc. are held with red oxide treated
01:35 PM ziper: is that bad?
01:35 PM gloops: how is the machine in general, everything ok with it do you think?
01:36 PM MrHindsight: these all came without threaded ends on the ball screws, so there no preload adjustment except for shimming...
01:36 PM MrHindsight: so they have ~40 thou last for X and Y
01:37 PM MrHindsight: and a few thou for Z
01:37 PM MrHindsight: the vertical supports could be made of steel to keep it from twisting
01:38 PM MrHindsight: they stiffen the top of the gantry with two steel linear bearings
01:39 PM MrHindsight: I can easily twist the gantry with one human arm
01:40 PM gloops: 12mm die on the end?
01:41 PM gloops: twist the gantry? you mean move one side when the other is held, or twist the Y rail?
01:42 PM MrHindsight: they grind the ball screw ends down to 3/8" and place them in floating skate bearings
01:43 PM gloops: ive got deflection issues with the gantry i made - from 2.5 inch heavy gauge tube, it is an important area to get right
01:43 PM MrHindsight: the bearings are in an oversized pocket
01:44 PM MrHindsight: it's like a HS project
01:44 PM MrHindsight: HS = high school
01:44 PM gregcnc: but they're just designed and built to turn scrap metal into smaller scrap metal?
01:44 PM gloops: well, dont forget, chinese machines are made on chinese machines lol
01:44 PM MrHindsight: pretty much
01:44 PM MrHindsight: you learn on the first one
01:45 PM MrHindsight: then hopefully do a better job before shipping them
01:45 PM MrHindsight: crunchy linear bearings as well
01:46 PM gloops: there was someone on facebook who paid 10k for an 8x4 and had some issues with it, he did get it going right in the end though - had to rewire the whole thing
01:46 PM MrHindsight: everything comes with e thin coat of dirt
01:46 PM gloops: it will soon rub in
01:46 PM MrHindsight: like it's fist coated in oil then left in a dust storm
01:47 PM gloops: you probably have to expect some minor issues
01:47 PM MrHindsight: or possibly the components are warehoused on a dirt floor
01:47 PM gregcnc: that is very likely
01:48 PM gloops: ive had an email asking if i want the ends of my ballscrews machining for another $9 each, its well worth it for that money - if they do it right
01:49 PM MrHindsight: off center just for fun
01:50 PM gloops: probably be some kid whos been on the job 16 hours, and we are keeping this going by buying from them
01:54 PM MrHindsight: probably an old shop
01:58 PM gloops: my screws will be weighting the tarpaulin on the roof down
02:00 PM MrHindsight: https://imagebin.ca/v/3e0e3tvKAbA7 https://imagebin.ca/v/3e0eazowD1Fv https://imagebin.ca/v/3e0eqIL51FqR typical new factory space there
02:02 PM gregcnc: I almost had to machine the end of a planetary roller screw, the though of scrapping a 4kUSD screw made me nervous so I convinced the client to buy finished.
02:02 PM MrHindsight: yeah, just in case
02:03 PM gloops: well mine are only a couple hundred quid, c7, no pressure on
02:05 PM MrHindsight: I have to find those pics of the shop floors made of dirt with the workers sleeping on them
02:08 PM MrHindsight: every time I went shopping there for fasteners they were in wooden bins, often away from water
02:10 PM gloops: pretty much like it was here 150 years ago, industrial revolution
02:11 PM MrHindsight: https://static.wixstatic.com/media/23307a_b4bdbb0b01fe4e68b3748b44fbb50dec.jpg mine probably came from here
02:13 PM MrHindsight: http://l7.alamy.com/zooms/dd4704de44e741129e454bc531aab889/hardware-shop-in-mong-kok-kowloon-hong-kongchina-d96m2y.jpg I wish we had metal shops like these
02:14 PM MrHindsight: metal supermarkets are close to it
02:15 PM gloops: lol
02:20 PM HighInBC: MrHindsight: I wish I had a magic door to Shenzhen I could use any time I needed parts
02:20 PM gloops: we are lucky to have a few stockholders in our town - http://www.barrettsteel.com/Distribution-Network/General-Steels/Distributors/C-Roberts-Steel/Hollow-Sections.aspx
02:21 PM MrHindsight: HighInBC: or like a flying carpet that Ali Baba had? :)
02:22 PM HighInBC: better than ali express
02:22 PM MrHindsight: the problem is that you can't really see what you are getting with the baba
02:23 PM MrHindsight: no stinky tofu to guide your way to the mall
02:27 PM MrHindsight: https://imagebin.ca/v/3e0n3WS5yLHy motor end of ballscrews
02:28 PM MrHindsight: there are four screws that hold that in, if you could lock each screw then you could set the preload
02:28 PM gregcnc: is that a single fidget spinner support bearing?
02:29 PM MrHindsight: yup, you can see the coupling inside
02:30 PM MrHindsight: the other end is just a bearing in an oversized pocket
02:31 PM MrHindsight: amazingly the ID of the bearing is only +0.001" larger than the OD of the screw end
02:32 PM MrHindsight: their thinking might be that the coupling acts as a spring to provide preload
02:33 PM MrHindsight: or the extra play means more life on the bearings and lash is not an issue since the whole thing isn't square anyway
02:34 PM MrHindsight: whaddahyah want for $700
02:35 PM MrHindsight: gloops: do they have a minimum that you have to purchase?
02:36 PM gloops: no you can turn up with a van and buy for cash - well you still could last time i went
02:37 PM MrHindsight: anything ground or precision I have to order and have shipped
02:38 PM MrHindsight: metalsupermarkets does stock some drill rod but it's often already red oxide treated
02:38 PM gloops: where are you MrHindsight?
02:38 PM MrHindsight: near Chicago
02:39 PM gloops: no steel places round chicago? amazing
02:39 PM gregcnc: Adam's only has random stock
02:39 PM MrHindsight: there are but not for small orders of precision things like drill rod or ground stock
02:40 PM gregcnc: and nothing interesting like drill rod
02:40 PM MrHindsight: Ryerson, Central, Alro etc
02:40 PM gloops: theres probably only around 5% of the steelworks round her that there used to be
02:41 PM MrHindsight: all for big orders
02:41 PM gregcnc: mcmaster to the rescue, prices vary from pretty good to quite high
02:41 PM gloops: the place was a steelworks with houses thrown in
02:41 PM MrHindsight: also MSC, they tend to have ground stock local
02:42 PM MrHindsight: gloops: this area used to have lots of machine makers
02:42 PM gregcnc: i've never done willcall
02:42 PM MrHindsight: just west of the airport
02:43 PM MrHindsight: they drop ship as well
02:43 PM MrHindsight: to the will call
02:43 PM MrHindsight: depends on shipping rates
02:43 PM MrHindsight: drive to airport vs three boxes for $20 ea from three warehouses
02:45 PM MrHindsight: https://www.google.com/maps/@41.9847243,-87.9815777,17z wood dale
02:47 PM gloops: wow lot of lakes round there, looks like a good fishing place
02:49 PM MrHindsight: lots of lakes anyway also the most golf courses per capita than anywhere
02:50 PM MrHindsight: people head north for fishing
02:50 PM MrHindsight: got too polluted and over fished around here
02:51 PM gloops: i shoulda moved to america years ago, theres no room in this country
02:51 PM MrHindsight: gloops: are you in the south of England?
02:52 PM MrHindsight: lots of room in Canada
02:52 PM gloops: north
02:55 PM MrHindsight: trying to visit before the weather gets too poor
02:57 PM gloops: its been unseasonably warm, usually starts going downhill around october, first frosts anytime now
03:01 PM MrHindsight: same here
03:01 PM MrHindsight: >30C two weeks ago
03:02 PM MrHindsight: ~5C last night
03:06 PM Jymmm: UPDATE YOUR PHONE, there's a huge exploit announced today.
03:06 PM MrHindsight: some backdoor to track you and see your contacts and pics?
03:07 PM Jymmm: WPS2 AND SSH exploit
03:07 PM MrHindsight: patch the screen door

03:08 PM XXCoder: Jymmm: update phone what a laugh
03:08 PM XXCoder: 'as if theres update for phone
03:08 PM MrHindsight: yeah it sucks, it's like it's not even your phone with root access to you
03:08 PM Jymmm: https://www.youtube.com/watch?time_continue=265&v=Oh4WURZoR98
03:10 PM sync: XXCoder: only if you bought the wrong hardware
03:10 PM XXCoder: sync: wheres you been? 99% of phones dont get updates past a year or rarely 2
03:11 PM MrHindsight: XXCoder: see you are supposed to buy a new phone every year or two so that your client can get updates to the latest spyware
03:11 PM MarcelineVQ: sure they do, that final update that slows them down so you have to upgrade to continue doing anything useful
03:12 PM sync: XXCoder: I run hardware where I can just flash a stock android compiled from sources
03:12 PM MrHindsight: XXCoder: root access is kept from you to insure security
03:12 PM sync: so not having vendor updates is not an issue
03:12 PM MrHindsight: security from you
03:14 PM MrHindsight: every terrorist and child molester in recent history has used a phone, so it's for your protection
03:14 PM XXCoder: sync: nice what device is it? is it a phone?
03:16 PM sync: yes, it is a phone, currently a nexus
03:17 PM XXCoder: cool. been considering replacing my s4
03:19 PM MrHindsight: XXCoder: take a look at what is supported by https://lineageos.org/
03:19 PM MrHindsight: but pay attention to exact model numbers
03:20 PM MrHindsight: https://wiki.lineageos.org/devices/#samsung several S4's
03:20 PM XXCoder: how did you get that from frontpage?
03:21 PM Jymmm: https://arstechnica.com/information-technology/2017/10/severe-flaw-in-wpa2-protocol-leaves-wi-fi-traffic-open-to-eavesdropping/
03:21 PM MrHindsight: Jymmm: I have it under good authority that wifi is secure :)
03:22 PM Jymmm: MrHindsight: Yeah, so is the economy.
03:22 PM MrHindsight: XXCoder: https://wiki.lineageos.org/
03:22 PM XXCoder: ah
03:22 PM MrHindsight: so no worries
03:24 PM XXCoder: none of em is my model
03:25 PM XXCoder: sph-l720
03:25 PM MrHindsight: Jymmm: I took a stock glaxy phone and never ran the updates...
03:25 PM MrHindsight: Jymmm: then started to remove all the apps I never use
03:25 PM MrHindsight: and never gave any permissions to my contacts, images or texts
03:26 PM MrHindsight: after a week or so firefox started asking me for permission to my contacts, images and texts etc
03:26 PM XXCoder: http://www.lineageosroms.org/forums/forum/samsung/galaxy-s4-sprint-jfltespr/
03:28 PM MrHindsight: I can't even view images taken on the phone
03:29 PM MrHindsight: XXCoder: just be sure you really have the exact matching model
03:29 PM XXCoder: i know
03:29 PM MrHindsight: XXCoder: and that you have good rooting instructions
03:29 PM XXCoder: phone is already rooterd
03:29 PM MrHindsight: or backup phone :)
03:30 PM MrHindsight: nothing like having instructions with missing steps
03:33 PM XXCoder: yep
03:33 PM XXCoder: ah left
03:54 PM Deejay: gn8
04:10 PM CaptHindsight: XXCoder: yes?
04:11 PM XXCoder: ah yeah root yeah
04:11 PM XXCoder: essentally there was no instructions for me lol
04:11 PM XXCoder: it had patched 4.4.2 in days there was no root for it
04:12 PM XXCoder: so I flashed unpatched 4.4.2 kernel to it
04:12 PM XXCoder: rooted it, then flashed patched 4.4.2 back to it
04:13 PM XXCoder: with root I finally could install cwm and later updated rom
04:13 PM CaptHindsight: all these secure boot crypto crap SOC's are to keep you from getting root vs security for you
04:14 PM CaptHindsight: 20-30 years ago people wouldn't believe you if you told them that people would line up and pay for things that they don't own or control
04:17 PM XXCoder: indeed
04:17 PM cradek: eh, 50 years ago people rented their telephones from the phone company
04:17 PM cradek: you weren't allowed to plug your own device into "their" lines
04:18 PM XXCoder: that is true
04:18 PM XXCoder: good thing that ws overturned
04:18 PM cradek: it's not new
04:18 PM XXCoder: or I'd be unable to use tty.
04:18 PM XXCoder: in ye olde days that was nesscary
04:18 PM CaptHindsight: the difference is that people now think that they own their phones
04:19 PM CaptHindsight: in the past they knew that they rented
04:21 PM cradek: aren't there lots of carriers that let you just get a sim and use your own device? that's what I have
04:21 PM XXCoder: I need to get a new sinm
04:21 PM XXCoder: my phone have "sim disconnected" error pretty often
04:22 PM CaptHindsight: yes, you may own a sim and a phone, the OS however is not under your control until you root and install your own version
04:22 PM cradek: sure, I did that
04:23 PM CaptHindsight: XXCoder: yeah usually oxide on the sim connector contacts
04:23 PM cradek: and they have the wpa-supplicant fixes already set for the next build: https://www.cmxlog.com/14.1/maserati/
04:23 PM XXCoder: even though I never removed sim? hmm how do I fix it?
04:23 PM CaptHindsight: flash gold on the sim, god only knows on the sim connector contacts
04:24 PM CaptHindsight: XXCoder: might be as simple as removing the sim and putting it back in, wiping the contacts
04:25 PM XXCoder: ok
04:25 PM XXCoder: as well as try that\
04:25 PM CaptHindsight: slide it in and out a few times
04:26 PM XXCoder: already planned that
04:26 PM CaptHindsight: I've had to go as far as contact cleaner on a couple
04:26 PM CaptHindsight: IPA on q-tip and light rub
04:27 PM CaptHindsight: cradek: we have a few spare droid 4's since they are getting scarce
04:27 PM cradek: I have one extra...
04:27 PM CaptHindsight: started collecting <$40 ones on ebay that were in working condition
04:28 PM CaptHindsight: usb connectors tend to wear or snap off
04:30 PM XXCoder: well lets see if it worked
04:36 PM sadisticroot: The USB port on my Nexus 6 is shot
04:36 PM sadisticroot: So I have to use wireless charging
04:52 PM CaptHindsight: heh the pocket diameter is >1mm than the OD of the bearing on the other end of the ball screw
04:54 PM CaptHindsight: http://www.machinedesign.com/linear-motion/importance-ballscrew-end-fixity
04:55 PM CaptHindsight: oh well the image links are all broken now :(
05:21 PM SpeedEvil: archive.org?
05:22 PM CaptHindsight: I think they moved them
05:22 PM CaptHindsight: and didn't bother to check the image links
05:22 PM SpeedEvil: yes, but archive.org may have earlier copies of the whole site
05:22 PM CaptHindsight: great article
05:27 PM CaptHindsight: just the text portion
05:28 PM CaptHindsight: lots of the articles are cleverly hidden ads, this one was as well but filled with actual impartial design info
05:29 PM CaptHindsight: some are horrible, like want to know, send us your contact info
05:29 PM CaptHindsight: and we'll contact you
06:28 PM JT-Shop: http://gnipsel.com/images/chickens-2/10-16-17-c.jpg
06:30 PM Tom_itx: hah
06:30 PM Tom_itx: gettin big
06:35 PM JT-Shop: yea they are elbow to elbow on the roost at night... gotta add on to the roost soon and branch out
06:36 PM JT-Shop: 9 weeks old Wednesday
06:36 PM JT-Shop: you got some of this nice cool weather over there?
07:26 PM Tom_itx: was a very nice day here today
07:26 PM Tom_itx: mid to upper 40's starting out
07:28 PM gregcnc: capthindsight that article looked familiar I was looking at the Thomson catalog recently https://www.thomsonlinear.com/downloads/screws/Leadscrews_Ballscrews_Splines_cten.pdf
07:29 PM gregcnc: though it's the same as any other ballscrew catalog.
07:58 PM CaptHindsight: https://imagebin.ca/v/3e2P1fuo3qef the motor end of the ballscrew
08:00 PM CaptHindsight: if you change this up a bit to make it be able to be locked into a given distance from the face vs pressed up against it then it could be used to adjust the preload
08:01 PM CaptHindsight: https://imagebin.ca/v/3e0n3WS5yLHy the other side
08:02 PM CaptHindsight: I wonder if that was the original plan until someone cheaped out
08:02 PM CaptHindsight: or maybe they just didn't know how to do it right all along
08:05 PM CaptHindsight: it's the same configuration for the Y axis ball screw
08:16 PM CaptHindsight: http://www.vxb.com/6800RS-Bearing-10x19-Sealed-10x19x5-p/6800RS.htm these are the bearings used on each end of the ballscrews
08:16 PM gregcnc: it doesn't make any sense to me if that bearing isn't captured, but i'm about to fall asleep here
08:16 PM CaptHindsight: yes, from the factory it floats in the radial and axial direction on one end
08:17 PM CaptHindsight: and floats in the axial on the other
08:17 PM CaptHindsight: it's onluy captures in the radial direction on the motor end of the screw
08:17 PM gregcnc: so thrust goes through the helical coupling to the motor bearings
08:17 PM CaptHindsight: yes
08:18 PM CaptHindsight: and it had ~2mm of lash
08:19 PM gregcnc: was this the cheapest machine you could find?
08:19 PM CaptHindsight: the bearings could have been just solid pieces of steel and they would work the same
08:19 PM gregcnc: this is probably some ploy to steer would be machinists away from the trade
08:19 PM CaptHindsight: fresh from Automation technologies
08:19 PM CaptHindsight: he had a bunch in crates
08:19 PM CaptHindsight: hehe
08:20 PM CaptHindsight: maybe 3 years ago
08:20 PM CaptHindsight: this is my last one
08:21 PM CaptHindsight: so this should answer anyones questions about "well how bad can they be?"
08:21 PM CaptHindsight: I knew I had to rework them but this is a bit ridiculous
08:23 PM gregcnc: I found some FAG 7200 P4 bearings on ebay "slightly used" for 5$ each. Dunno what they used them for but they look like new
08:25 PM gregcnc: just a little bit more effort and an extra bearing would have made for a proper screw support.
08:26 PM CaptHindsight: https://imagebin.ca/v/3e2XG9SUECTF the bearing in the pocket on the opposite end of the screw
08:26 PM gregcnc: nice
08:26 PM gregcnc: just to make sure it whips a little, not a lot
09:09 PM nullifier: on my thk ballscrews there is a preloading nut on the driving side of the shaft
09:15 PM evilroot: Pretty sure the ballscrews on my bot are THK
09:15 PM evilroot: Would make sense given the linear rails are
09:19 PM ziper: whats the best way for an amateur to cut spur (or helical i guess) gears
09:22 PM Tom_itx: cutting helix gears probably isn't for amateurs
09:23 PM ziper: yeah i just wanted to show i dont discriminate
09:26 PM Tom_itx: archivist seems to be the gear cutter here
09:27 PM Tom_itx: but it's ~3AM where he is
09:37 PM jason__: Anyone know a reasonable assumption for the kerf of a laser cutter? 100W cutting 5mm MDF at 95% power, 3-4 passes
09:44 PM evilroot: Depends on the MDF
09:45 PM evilroot: But should be around .2mm
09:45 PM evilroot: Also speed/etc are a factor
09:46 PM evilroot: And why 95% power? Why not 100%?
09:47 PM jason__: The person at the place recommended 95% last time I cut MDF. Maybe they don't want to run it at 100% for some reason?
09:50 PM CaptHindsight: nullifier: yes, they didn't leave any threads on these
09:53 PM evilroot: What laser? Branded?
09:53 PM evilroot: Generally they will have a chart with all that info
09:54 PM evilroot: But generally speaking for 100W and MDF .2mm is about normal
09:54 PM evilroot: Maybe a bit less
09:56 PM evilroot: 5mm isn't too tough for a 100W tube, ought to only need 3 passes
09:56 PM gloops: plenty of expansion for that bearing lol
09:57 PM evilroot: Like most things, if in doubt do a few test cuts and see what happens
09:57 PM evilroot: Measure with a caliper
09:57 PM evilroot: Guessing you're doing a slot cut if kerf is a concern?
10:01 PM CaptHindsight: gloops: in case it grows
10:01 PM CaptHindsight: otherwise it might buckle the gantry :)
10:12 PM gloops: i wonder if its the right bearing? i bet you can get a bearing with those inner and outer sizes
10:14 PM CaptHindsight: looks like a 10 x 19 x 5 in this one
10:14 PM CaptHindsight: 10 x 20 x 6 might be what they had in mind, but you still have to shim it to adjust the preload
10:15 PM CaptHindsight: i reworked a few of these already
10:16 PM CaptHindsight: https://imagebin.ca/v/2apzmk7rpwvC a day or two + anodize time
10:17 PM CaptHindsight: everything is full of grit as well
10:17 PM CaptHindsight: like one step of the ball screw assembly is to drop it into a pile of dirt
10:23 PM MarcelineVQ: heavy enough in the air to gunk up parts, must be a lot of fun for workers to breathe
10:23 PM Tom_itx: CaptHindsight do you disassemble the ballscrews to clean em?
10:27 PM Tom_itx is now known as Tom_L
10:53 PM CaptHindsight: Tom_L: have to or they are crunchy, same for the linear bearings
11:11 PM archivist: ziper, a plastic helical http://www.collection.archivist.info/searchv13.php?searchstr=helical+PD
11:15 PM archivist: ziper basic arrangement for milling http://www.collection.archivist.info/archive/DJCPD/PD/2008/2008_02_28_cnc/P2210002.JPG
11:17 PM ziper: very nice, i'll ask some more in the morning if you dont mind
11:18 PM archivist: ziper, the code http://www.archivist.info/cnc/standard_clock_n_teeth.ngc
11:18 PM archivist: http://www.archivist.info/cnc/standard_helical_n_teeth.ngc
11:23 PM dioz: i need a toolbox that can fit a powerbar and 4 chargers
11:24 PM dioz: or bosch needs to make a multi-charger already
