12:43 AM Crom: before I do much more milling, I need to build an enclosure
12:45 AM MarcelineVQ: at least some cardboard shields to keep chips in the area :D
12:45 AM MarcelineVQ: what kind of materials are you working with?
12:53 AM Crom: trimming the bottom off insert holders right now. Logan 820 Lathe using an AXA needs 0.060" off the bottom for a 1/2 insert holder to get to centerline
12:56 AM rue_mohr: Crom, a plastic tub with the sides that get in the way cut out
12:59 AM Crom: great idea... I have 2 ice cream tubes that would work well for that
12:59 AM Crom: tubs
01:00 AM rue_mohr: 8-| I could make a manual hybrid cnc machine, that would be manual control, but be able to do things like circles
01:00 AM rue_mohr: virtual rotary table
01:01 AM rue_mohr: this would fit perfectly into my "micro manufacturing" goal
01:01 AM rue_mohr: ooo
01:02 AM Crom: I'm waiting for some money to come in, then I'm getting the CNC fusion X,Y,Z kit $619
01:02 AM rue_mohr: "set linear path waypoint" "set circle centre"
01:05 AM rue_mohr: Crom, I'm thinking of upping my budget to $40 for my next cnc
01:05 AM rue_mohr: http://ruemohr.org/~ircjunk/projects/cnc4/p1080740.jpg
01:05 AM RyanS: I made a virtual indexing head, but stand alone
01:05 AM rue_mohr: this one is doing really nicely for me tho
01:05 AM rue_mohr: at some point I have to move the uprights back 2" (math, oops)
01:05 AM RyanS: $40 including all the parts you recycle or salvage? :-)
01:11 AM rue_mohr: yea
01:11 AM rue_mohr: I didn't go overbudget on that one
01:12 AM RyanS: jthornton: do i need THCAD-10 or 300 for hypertherm?
01:12 AM rue_mohr: I bought the pipe T and the cutrin rail
01:12 AM rue_mohr: (some 3d plastic in there too)
01:12 AM rue_mohr: and the 608's
01:13 AM rue_mohr: which are paired with thrust bearings made from 4mm bb's
01:16 AM RyanS: hmm, i dont have electronics on hand, just plate and bar stock, :-( have to source everything else
01:33 AM gloops: https://pastebin.com/JpsjKHGz < non working hal file, tried putting 2 joints on 1 axis, 2nd joint is xo
01:36 AM gloops: or maybe its the ini https://pastebin.com/WZz1BhKC
02:03 AM archivist: line 8
02:07 AM archivist: gloops, ^^
02:09 AM gloops: in the hal?
02:09 AM gloops: so that needs to be..0,1,2,3?
02:10 AM gloops: or just 4 0s
02:10 AM archivist: well 3 0 and you wanted 4
02:10 AM gloops: right, well spotted
02:10 AM archivist: hence why stepgen.3 was not there
02:11 AM gloops: correct, its loaded, thanks once again
02:12 AM gloops: im going to post copies of this - working hal and ini file, when i get going, its a common thing people are trying to do
02:12 AM archivist: the error message had all the clue, now you will find that sort of error more obvious :)
02:13 AM gloops: X is not moving - but that is explained in the tutorial, ill sort that
02:14 AM gloops: yes it was there in the error message, tbh i was only looking at the areas id changed, expecting a missing '.' or something - did not look above
02:14 AM gloops: the double motor axis wont move until homed
02:16 AM archivist: spent many years as a programmer, used to looking at listings
02:18 AM gloops: well we know bit more about how it works anyway
02:18 AM gloops: or i do i haha
02:20 AM gloops: its just the homing to sort now, as i say ive just been having 10 minutes or so with this 2 joint config, there is no machine for it yet so got weeks to crack it
02:21 AM MarcelineVQ: got tape on your motor shafts? there's something satisfying about watching that tape turn to specific spots
02:22 AM archivist: I was at that stage in 2008 http://www.collection.archivist.info/searchv13.php?searchstr=cnc+test
02:23 AM Deejay: moin
02:27 AM gloops: looked slightly more involved archivist in those days
02:28 AM gloops: not even got the motors Marcel, just getting ready in time for them - nothing worse than having a machine built then cant get it to run
02:28 AM MarcelineVQ: he's certainly got the image of 'the tinkerer', parts and equipment covering every surface
02:28 AM archivist: just a few drivers and a power supply, home made bob though
02:29 AM archivist: a clear bench is an unused bench!
02:32 AM archivist: when you run out of bench, get some chipboard/mdf and use that as a temporary fixture http://www.collection.archivist.info/searchv13.php?searchstr=wormtest
02:33 AM gloops: trouble with more benches, they just become shelves
02:34 AM gloops: any flat surface ends up covered
02:36 AM archivist: about as tidy as my electronics bench gets http://www.collection.archivist.info/archive/DJCPD/PD/2013/2013_08_14_Lounge_Electronics_bench/IMG_1643.JPG
02:36 AM MarcelineVQ: I suspect I'm gonna need a labelmaker as parts arrive for projects if sanity is to be preserved
02:37 AM archivist: barcodes and a software map!
02:37 AM archivist: http://www.collection.archivist.info/shelfview.php?src=artitle&locid=197
02:37 AM MarcelineVQ: My space isn't so large as to warrant a map, hopefully
02:38 AM archivist: the archive part of me caused that
02:40 AM MarcelineVQ: how many multimeters and scopes does one man need :>
02:41 AM archivist: one of each and a spare for parts
02:43 AM MarcelineVQ: idk, got this little meter out of china that does volts/amps/ohms/rms, it's half the size of my hand, surely it won't last like that gear there but it's got a heck is a small footprint
02:44 AM MarcelineVQ: *of a small
02:45 AM archivist: I have a multimeter for dragging about but that cannot measure what that stack can
02:52 AM MarcelineVQ: You must have some pretty interesting projects given all the things you have pictures of
02:54 AM archivist: I am liable to pick up some interest and get bits to experiment and learn
02:55 AM archivist: measurement is pretty common to some of the projects
02:57 AM archivist: so I watch stuff like https://www.ebay.co.uk/itm/Hilger-Watts-Square-Block-Level/122761593465
03:04 AM archivist: useful for setting up your home made cnc
03:07 AM archivist: a whatsit http://www.hyperkitten.com/pics/tools/fs/scale1.html
03:09 AM MarcelineVQ: hmm
03:11 AM MarcelineVQ: the scale going in two directions on the bottom one feels like it should be a hint, but I've no idea
03:12 AM MarcelineVQ: another hint is that these lines are at a slight angle, also no idea what that's hinting at
03:12 AM archivist: all I can think of is setting dividers
03:12 AM MarcelineVQ: unless they're rasp sizings or something
03:13 AM MarcelineVQ: but that's usually a steeper angle
03:14 AM archivist: here is one I have http://www.collection.archivist.info/archive/DJCPD/PD/2014/2014_04_01_tools_clock/IMG_1780.JPG
03:16 AM archivist: I never found that on a google search until my pics showed up
03:18 AM MarcelineVQ: it's not immedtialy appearant to me how to use these
03:18 AM MarcelineVQ: including yours I mean
03:22 AM RyanS: I saw the Wallace and Gromit exhibition in Melbourne and had never seen any of the movies. I watched them all and thought of the British inventors in their home workshop, on this very channel. Do any of you have a dog and like cheese? :-)
03:27 AM archivist: MarcelineVQ, I think mine is for setting http://www.ebay.co.uk/itm/BT-2-X-Machinist-Metal-Firm-Friction-Joint-Outside-Inside-Calipers-200mm/282128236001
03:27 AM archivist: or checking what size they are set to
03:28 AM gloops: Ryan real wensleydale cheese is made from sheeps milk, pretty expensive and scarce these days
03:30 AM RyanS: so I'm almost close to finding a real life Wallace?!
03:30 AM archivist: and many geeks have other pets too
03:30 AM gloops: ive got goats and ducks
03:30 AM RyanS: are you "crackers about cheese"?
03:30 AM MarcelineVQ: like iguanas, and bees
03:30 AM archivist: others have chickens and sheep
03:31 AM gloops: oh, and bees haha
03:32 AM RyanS: I have a cat, but I'm not British, although I do like cheese
03:32 AM gloops: have a look at heath robinsons machines
03:32 AM archivist: I admit to beans on cheese on toast
03:35 AM RyanS: I guess being like Wallace means your inventions blow up or malfunction --nobody wants to admit that :P
03:37 AM gloops: i doubt many inventions work first time, the concept is a process, it isnt finished until it is
03:38 AM RyanS: I'd never heard of Wensleydale until I watched that show. I think the moon is made of Wensleydale cheese haha
03:39 AM RyanS: yeah but not too many inventions shoot porridge in your face
03:39 AM MarcelineVQ: There's probably a few, not much of a market for it I fear
03:41 AM gloops: who was that engineer who designed the first iron rail bridge, they built his bridge but the tension got too much for him, he threw himself off it the night before the first tain was due to pass over it
03:41 AM gloops: the train was not cancelled - passed over with no problem
03:41 AM MarcelineVQ: "heard about the guy that made the suspention bridge? the tension was too much for him"
03:41 AM gloops: yes...haha
03:42 AM RyanS: it would be handy to have a dog who could fix your inventions
03:44 AM RyanS: or Rudolph Diesel who is believed to have been killed by the German navy for selling plans to Britain and Germany --oops
03:51 AM RyanS: I also watched something about the inventor of the screw propeller get, well screwed out of any royalties
03:52 AM RyanS: so actually, he was royally screwed
03:56 AM MarcelineVQ: :>
04:05 AM -!- #linuxcnc mode set to +v by ChanServ
04:38 AM gloopsk: well one nice heavy bearing arrived
04:39 AM MarcelineVQ: what shall it bear?
04:39 AM gloopsk: unfortunately Ichs solution to a rotating nut will not work
04:39 AM gloopsk: it was curiousity purchase really, Ichs had the suggestion of using a pillow bearing to hold a ballnut
04:39 AM gloopsk: this has loads of axial movement
04:39 AM archivist: heh
04:40 AM gloopsk: shame as i have no other use at all for a 30mm cast iron flanged bearing
04:40 AM MarcelineVQ: you will
04:41 AM gloopsk: cant think of any immediate application for a 30mm shaft
04:42 AM archivist: would almost hold a ballscrew I have
04:42 AM gloopsk: no wait, there is a grubscrew...
04:42 AM gloopsk: i can move this by hand 1mm
04:43 AM archivist: I did say they are agricultural :)
04:44 AM gloopsk: or should i say there is a threaded hole - no screw
04:44 AM MarcelineVQ: grease nipple?
04:44 AM gloopsk: its pressed in out of square what a load of junk
04:44 AM gloopsk: could be yes Marcel
04:45 AM gloopsk: think its just a retaining screw
04:46 AM MarcelineVQ: If it doesn't have a grease nipple, that hole is almost surely for one
04:46 AM gloopsk: just appears to meet the outer case
04:47 AM MarcelineVQ: e.g. http://media.rs-online.com/t_large/F7508964-01.jpg
04:47 AM MarcelineVQ: are you talking about the center one or the outside?
04:48 AM MarcelineVQ: that is to say, are you speaking about an area that appears to be the set screw in that pic or the nipple?
04:48 AM gloopsk: you are right
04:48 AM gloopsk: http://www.ebay.co.uk/itm/UCF-Metric-Self-Lube-Square-Flange-Pillow-Block-Bearing-UCF201-UCF212/190676665609?
04:49 AM gloopsk: not exaggerating, the bearing is 2mm out of square
04:49 AM MarcelineVQ: self lube, grease nipple, confused seller hehe
04:49 AM gloopsk: in fact more
04:50 AM MarcelineVQ: So was is idea to have one of those on either side of the nut?
04:51 AM gloopsk: the body of the nut fits in this
04:51 AM MarcelineVQ: Oh interesting
04:51 AM gloopsk: pulley bolted to nut - rotating ballnut, with 1mm slack
04:52 AM gloopsk: yes good idea
04:52 AM gloopsk: with the right bearing
04:52 AM archivist: need two, to take up play
04:52 AM gloopsk: this weighs 4lbs
04:52 AM archivist: but they are ok when in combine harvesters!
04:53 AM gloopsk: you could fix it with the back of the bearing against the flange
04:53 AM archivist: muck spreaders etc
04:53 AM gloopsk: i dont think ill be anything with it though
04:53 AM MarcelineVQ: something will come up, maybe you'll make a rotary welding table with it down the road
04:53 AM gloopsk: a pair would do for a rotary axis
04:53 AM gloopsk: its ok radially
04:54 AM gloopsk: it would be good with a heavy pole for tamping tarmac down
04:56 AM gloopsk: so, if i want 500 ipm...im going to have to earn it
05:09 AM XXCoder: finally got dehumidifier
05:09 AM XXCoder: plugged it and went off to eat dinner
05:09 AM XXCoder: come back it made a spoonful of water so far
05:10 AM gloopsk: whats it taste like?
05:10 AM archivist: his own sweat :)
05:10 AM XXCoder: ballsack sweat
05:11 AM XXCoder: I dont plan to drink it though, as its not potable water
05:11 AM archivist: did you get a cheap or better one
05:12 AM XXCoder: cheap for now. I will have just barely enough money to cover rent this month
05:12 AM XXCoder: move was expensive
05:13 AM gloopsk: extractor fan helps with humidity, also removes the heat as well though
05:13 AM XXCoder: gloopsk: yeah though my room has its own heater
05:13 AM RyanS: it tastes like the satisfaction of having less rust
05:14 AM XXCoder: and no ventalation lol gonna love 1940s
05:14 AM XXCoder: I have his and hers closets lol as my room is old master room
05:14 AM XXCoder: hers has 2 high shelves for shoes :P
05:15 AM RyanS: XXCoder are you building a time machine :-)
05:15 AM XXCoder: lol
05:16 AM XXCoder: nah house was made in 1946
05:16 AM XXCoder: then SUPER-modernized
05:16 AM XXCoder: but theres some stuff that just can't be done apparently
05:17 AM XXCoder: unless you know someone who can do nonecludian building?
05:20 AM MarcelineVQ: archivist: are your barcodes rfid?
05:22 AM XXCoder: https://www.missyempire.com/you-vs-the-kardashians/ lol
05:22 AM RyanS: google isn't much help https://lovecraftianscience.wordpress.com/2014/01/23/lovecraft-and-mathematics-non-euclidean-geometry/
05:23 AM MarcelineVQ: if you believe lovecraft non-euclidean geometry is just geometry that invovles heavy use of the word cyclopean
05:24 AM RyanS: would you like giant squid thing with that
05:26 AM XXCoder: heh
05:26 AM XXCoder: you ever read "he who built a crooked house"?
05:26 AM RyanS: hmm never heard of him
05:26 AM XXCoder: you can download it pretty quickly, and you probably can finish reading in a hour
05:26 AM XXCoder: its short story
05:27 AM XXCoder: basically builder was comissioned to build a unfolded hypercube building. very possible as its "flat" or 3d.
05:27 AM MarcelineVQ: short stories are great, I remember reading one that was quite good, flowers for algernon, I don't recall what it was about though
05:27 AM XXCoder: earthquake happens and it folds into hypercube
05:27 AM XXCoder: rest is spoiler
05:31 AM archivist: MarcelineVQ, no, just normal visible ones
05:31 AM MarcelineVQ: dang, so if you misplace something it remains misplaced
05:32 AM XXCoder: MarcelineVQ: few choices https://www.librarything.com/search.php?search=flowers+for+algernon&searchtype=newwork_titles&searchtype=newwork_titles&sortchoice=0
05:32 AM archivist: until one stockchecks a shelf/box
05:32 AM archivist: http://www.collection.archivist.info/searchv13.php?searchstr=barcodes
05:32 AM MarcelineVQ: it's my little joke related to the story XXCoder
05:32 AM RyanS: eww, he was a racist like Aldous Huxley
05:34 AM XXCoder: well its interesting enough
05:37 AM MarcelineVQ: archivist: where do you pick up a little barcodes like that?
05:38 AM MarcelineVQ: I don't have an inventory that would need them but it's interesting still
05:38 AM archivist: MarcelineVQ, I got lucky a real of 20k ish stickers on ebay
05:38 AM archivist: reel
05:39 AM MarcelineVQ: that is good, keeps the numbers similar
05:39 AM archivist: I hope I never run out
05:40 AM archivist: it has made finding a manual trivial these days
05:41 AM XXCoder: 20k stickers?
05:42 AM archivist: the little yellow barcode stickers seen in these images http://www.collection.archivist.info/searchv13.php?searchstr=barcodes
05:43 AM MarcelineVQ: are they plastic coated or full paper?
05:43 AM archivist: seem plastic ish coating
05:43 AM XXCoder: interesting
05:43 AM MarcelineVQ: should last a lot longer then
05:44 AM archivist: not seen any fading yet
05:44 AM XXCoder: I wonder if those tiny stickers is readable b y cuecat heh
05:44 AM MarcelineVQ: surface tends to get weird on paper-only ones, probably from moisture changes
05:45 AM archivist: the reader has to be a good quality to read
05:45 AM MarcelineVQ: for labels in general I mean, I don't know anything about barcodes
05:46 AM archivist: about time for another attempt to get to supermarket, roads blocked earlier
05:46 AM XXCoder: https://www.theguardian.com/environment/2014/aug/27/giant-wasps-nest-single-bed-spare-bedroom-winchester
05:46 AM XXCoder: sleep tight
05:46 AM MarcelineVQ: whacky. wasps are easy to deal with but only if they don't surprise you :(
05:47 AM MarcelineVQ: wish there was better pictures, wasps around here don't make them like that
05:48 AM XXCoder: those wasps figured how to work with queens
05:48 AM XXCoder: because queens kill each other
05:48 AM XXCoder: so they manage em to make sure queens never meet each other
05:48 AM XXCoder: as a result, new wasps breed that build HUGGGGE nest
06:40 AM gloopsk: all the wasps in a nest are sisters
06:40 AM gloopsk: same for bees and ants
06:40 AM XXCoder: i know
06:41 AM gloopsk: ants are wasps, or wasps are ants with wings
06:44 AM MarcelineVQ: afaik wasps came first, which is why the ant breeders can pop out wings
06:45 AM XXCoder: like we need more wasp species
06:45 AM MarcelineVQ: termites come from cockroaches interestingly, their breeders have I think 4 interesting wings
07:54 AM Jymmm: XXCoder: One more wasp for ya... https://www.youtube.com/watch?v=TQNgxJdqzm4
07:54 AM Jymmm: XXCoder: Agressive as fuck!
08:00 AM MarcelineVQ: just think, they've been playing that game for millions of years
08:01 AM MarcelineVQ: all the way back to when tarantulas were the size of dogs
08:03 AM * skunkworks wonders what conversation he walked into...
08:03 AM MarcelineVQ: skunkworks nature is full of terrors
08:03 AM Jymmm: XXCoder: MarcelineVQ Oh this is even better... https://www.youtube.com/watch?v=MnExgQ81fhU
08:04 AM MarcelineVQ: hoho that guy is an idiot, but he's fun to watch
08:04 AM Jymmm: skunkworks: "How to mill spiders in three easy steps"
08:04 AM MarcelineVQ: 'spider hydraulic control, how ichor can bring your mill new life'
08:05 AM skunkworks: ah - I can add to this conversation. My reaming went great!
08:05 AM skunkworks: 1500rpm - 6ipm
08:05 AM Jymmm: skunkworks: woohoo! flying wasp reaming!
08:05 AM Jymmm: 6 ipm?! wow
08:06 AM skunkworks: I the aluminum - 2000rpm 12ipm
08:06 AM Jymmm: skunkworks: what are you doing that you need that finish?
08:07 AM skunkworks: it is to press 1/8 dowel pins in.
08:07 AM Jymmm: skunkworks: ah
08:41 AM skunkworks: https://www.youtube.com/watch?v=gDXWo70xVwA
08:42 AM skunkworks: I think that machine is just slightly older than our IIIb
08:49 AM skunkworks: That is a millwaukee-matic II :P
08:53 AM Loetmichel: Hmm, thats a new one: modified the past PC of a whole pallet, did the end test: no function... hurrying because the truck of the carrier was ordered for 40 minutes later to deliver it to the customer... So a quick check revealed that the PSU was dead. no 5Vsb...
08:55 AM Loetmichel: so i took the PSU apart (non-standard dell pc, SFF) and found: a broken lead to the main fet gate ... soldered good, not broken at the to220, but halfway up. plain teared off...
08:55 AM Loetmichel: ... and then of course the carrier arrived 20 minutes early... so we had to rush to get the pallet shrinkwrapped. :-)
09:01 AM Jymmm: Loetmichel: lovely
09:04 AM archivist: I wanted to check if the earth was flat https://www.ebay.co.uk/itm/Hilger-Watts-Precision-Water-Level/122761493844
09:04 AM archivist: not paying that much!
09:09 AM gloops: https://www.youtube.com/watch?v=k3MG7ww49A8
09:10 AM gloops: how?
09:10 AM Jymmm: archivist: clear 24,901 mile hose and soem food coloring?
09:11 AM archivist: effin moon shifts the water though
09:12 AM gregcnc: gloops what are you asking?
09:12 AM gloops: hows he getting that speed
09:14 AM gloops: well, can see how hes getting it, i doubt he can cut much at that though
09:14 AM gregcnc: some people build for the sake of building
09:16 AM gloops: noisy
09:18 AM gregcnc: did he have a video of that machine cutting?
09:23 AM gloops: didnt see one, they do cut over 600ipm, not seen 40 inch per second though
09:24 AM pcw_home: Its got a 10 mm ball screw with the stepmotor geared up 3.5 to one so not great accuracy
09:25 AM archivist: if you want a lot of speed strap a rocket on http://www.bbc.co.uk/news/uk-england-cornwall-41749466
09:26 AM MarcelineVQ: I like that nut drive
09:26 AM gloops: not much power left to cut with either
09:27 AM pcw_home: I douse show that rotating nuts work well at high speeds ( no whipping at 6000 RPM equiv ball screw speed )
09:27 AM MarcelineVQ: two thrust bearings and a toothed nut I suppose
09:27 AM gregcnc: machine design isn't easy
09:27 AM pcw_home: does
09:27 AM gloops: allegedly rotating ballnut is good to 20000 rpm
09:28 AM pcw_home: most are not designed for that kind of speed though
09:28 AM gregcnc: it won't handle 20k
09:28 AM gregcnc: the returns and ball contact limit speed
09:28 AM pcw_home: I would not want to be near it at 20K
09:28 AM MarcelineVQ: shucks buster, you want speed, get yourself some air pistons :>
09:29 AM gloops: in theory could move that machine at 2000 metres per minute
09:29 AM gloops: 80000 inches
09:30 AM gloops: 16 mm screw starts to rattle 1000rpm
09:31 AM gregcnc: critical speed is dependent on several factors
09:32 AM MarcelineVQ: like whether you have a system of supports them that were themsleves on a rail, with the tops connected by springy materials for spacing, and could slide along as the nut did, trading a bit of travel range for screw support
09:36 AM gloops: ok you can double it
09:49 AM skunkworks: archivist, I heard that on the news this morning.
09:50 AM archivist: skunkworks, last couple of days it gets mentioned
09:50 AM archivist: going to upset the yanks when we break the record properly :)
09:51 AM skunkworks: Are there places to actaully run that fast? or do they have to bring it to the salt flats?
09:51 AM gregcnc: it's just an airplane that can't get off the ground
09:52 AM archivist: skunkworks, I think they are taking it to south africa somewhere
09:52 AM skunkworks: ah
10:00 AM archivist: northern cape https://en.wikipedia.org/wiki/Bloodhound_SSC
10:09 AM gloops: its is like an aeroplane, only the wings dont lift it up, they press it down
10:45 AM IchGucksLive: hi all ;-)
11:03 AM IchGucksLive: later :p
11:37 AM Simonious: Does fusion360 include FEA worth using?
11:43 AM Simonious: does basic solidworks?
11:47 AM archivist: was an extra on SW
11:47 AM Simonious: yeah, I don't have it
11:47 AM Simonious: I've got the cheapest package they sell
11:54 AM IchGucksLive: hi
11:55 AM gloops: freecad?
11:55 AM IchGucksLive: Simonious: https://en.z88.de/
11:56 AM IchGucksLive: gloops: first chips made
11:57 AM gloops: new machine Ichs?
11:57 AM IchGucksLive: i got 4 to be mounted in basement
11:58 AM gloops: lucky to have a basement, good for noise
11:58 AM gloops: im looking at xmas to be finished
11:58 AM IchGucksLive: what is the hint
11:59 AM gloops: waiting for the boat
11:59 AM IchGucksLive: boot has a leek as i touched a aircraftcarrier
12:00 PM IchGucksLive: and the gfk of the carrier go also dameged
12:01 PM gloops: well, gtg bbl
12:06 PM miss0r: Jymmm: did you have any luck with your project of desolving the alu?
12:08 PM Crom: I so would like to add a basement to this house
12:08 PM IchGucksLive: its most uncomen in the usa
12:09 PM IchGucksLive: thats why energie cost over house livetime is so big
12:09 PM IchGucksLive: the Air isolates from ground
12:09 PM Crom: Only would cost $200,000USD, house is appraised at $149,000
12:09 PM miss0r: hehe
12:09 PM Crom: 2 years ago, we had snow, 1st time is 15 years...
12:09 PM IchGucksLive: houseprices in usa are so high
12:10 PM miss0r: Thats a pretty cheap house
12:10 PM miss0r: how big is it? /Where can you get a house for that?
12:10 PM IchGucksLive: here in countryside europ it will build you a full 3storige
12:11 PM miss0r: here in Denmark, that will not even buy my house... which I got realy cheap
12:11 PM Crom: 3bed,2 bath 1 story, HUD repo 20 years ago for $88,000
12:11 PM miss0r: holy....
12:12 PM sync: yeah housing is cheap in the us
12:12 PM sync: but it also is nothing to write home about
12:12 PM miss0r: I got 1bed, 1 bath, 1 story for $175.000 usd 5 years ago
12:12 PM sync: I mean, crawlspace? seriously?
12:12 PM Crom: It's a slab house, no crawl space :(
12:13 PM Crom: 1100Sq Ft
12:13 PM miss0r: Well. it depends how you look at it. Here in denmark the basement has a list of requirements to be 'used for living'. Mine didn't, so it didn't count. althou the basement is the same size :)
12:14 PM miss0r: Basically my basement fails on the criteria that the windows has to be larger - so they can be used for escape route, incase of fire... lol
12:15 PM miss0r: But I wouldn't want to be without a basement. seriously! Thats where I keep my man cave :]
12:16 PM JT-Shop: mine is my beer cave
12:16 PM IchGucksLive: beer
12:16 PM the_wench: I am not your waitress!
12:16 PM miss0r: beer
12:16 PM the_wench: I am not your waitress!
12:16 PM miss0r: ... :)
12:17 PM miss0r: so, if a few of us write beer fast in a row, we can get an excess flood here :D
12:19 PM miss0r: I have a 120" projector setup with a 2500watt soundsystem (yes, real RMS) that I hardly ever get to use... The house pretty much needs to be vacant for me to use it
12:38 PM miss0r: Can any of you guys recommend a "good for the price" QTCP?
12:41 PM JT-Shop: QTCP?
12:41 PM miss0r: QCTP*
12:41 PM miss0r: Quick change tool post
12:41 PM JT-Shop: ah
12:42 PM miss0r: I have one of these fixed types, where you have to shim the tools
12:42 PM miss0r: and it is starting to get old
12:44 PM skunkworks: lantern?
12:45 PM miss0r: now.. Whatever this type is called: http://www.kanabco.com/vms/Media/cutting_tools_lathe/tool_post_new.jpg (google images)
12:46 PM miss0r: no*
12:46 PM gloops: quickchange
12:46 PM gloops: i sold one last year for £80
12:47 PM miss0r: In my book, this is a quickchange: http://www.scottmachinery.co.nz/scaleimage.php?type=fill&width=1300&height=900&file=QzpcRGF0YVxDb21tb25cRXhvbmV0IDYwMDBcSW1hZ2VzXFdlYlxMYXJnZVxXRUItUkFQSUQgUVVJQ0sgQ0hBTkdFX18xLmpwZw==
12:47 PM gloops: same thing?
12:47 PM gloops: ahh no
12:47 PM gloops: sorry, only glanced at the first
12:48 PM miss0r: no worries :)
12:48 PM miss0r: Actualy, i'm in the process of cleaning in here at the moment... For whatever reason I have a Starret No196 dial indicator.. its a 0.001" one... This is a metric only workshop(aside from some odd sized taps)... Anyone interrested?
12:49 PM gloops: no good for me i work to .0001
12:50 PM miss0r: I only work to 0.001... But metric :]
12:50 PM gloops: lol, i do put a dial on sometimes
12:52 PM miss0r: I use a dial several times'a'day
12:52 PM gloops: Quick change tool post with 2 tool carriers (#191801267933) £54.50
12:52 PM miss0r: Lining up stuff. comparing material thickness
12:53 PM miss0r: Is there a link in there somewhere?
12:53 PM gloops: was only 50 quid - i got one in a box of misc, somehow one of the carrier had been sheared off, didnt fit anything i had anyway
12:53 PM miss0r: The one you sold? :-/
12:53 PM gloops: yeah
12:54 PM miss0r: Bleh. Do me a solid, and turn back time one year, and sell it to me instead
12:55 PM gloops: it was sound, couldnt see any distortion or other damage, must have taken some almighty force to snap a mounting off though
12:55 PM miss0r: its what happens, I guess.
12:55 PM miss0r: I have been toying with the idea of building one myself, but time is not what I have too much of at the moment
12:56 PM gloops: would be easy enough to make a version of it
12:56 PM gloops: with your mill anyway heh
12:57 PM gloops: the carriers go for daft money, probably worth making to sell, you can have every tool you use ready mounted if you have enough carriers
12:57 PM IchGucksLive: does someone know if cmorney showes up sometimes
12:57 PM miss0r: sure. thats the idea. about having them mounted ready, atleast. But its the carriers i'm worried about - theres alot to make, and that takes time
12:58 PM IchGucksLive: or does he have s git to the pncconf
12:59 PM IchGucksLive: hazzy: now it hit 10k on youtube so it woudt be good to be inside
12:59 PM miss0r: what hit?
12:59 PM gloops: Ichs dont remember seeing him
12:59 PM IchGucksLive: he is realy bussy
01:01 PM miss0r: IchGucksLive: What just hit 10k on youtube?
01:01 PM IchGucksLive: my advise on 7i92
01:01 PM miss0r: link? (lets make it 10001 hits)
01:01 PM IchGucksLive: parport to eth
01:02 PM IchGucksLive: no need to
01:03 PM miss0r: I need to get acquainted with thoes mesa cards. I have to do a retrofit of my mill sometime in the future
01:03 PM miss0r: no need sure. but I want to
01:03 PM IchGucksLive: miss0r: https://www.youtube.com/channel/UCmwhCL92ZQRSVqFe3jGwJSQ/videos
01:04 PM miss0r: It seems i've stumbled across some of thoe videos before
01:05 PM IchGucksLive: sort by interest
01:06 PM IchGucksLive: the grayscale milling got the most
01:07 PM Jymmm: miss0r: Haven't started yet, but I'll let you know when I do =)
01:07 PM IchGucksLive: Jymmm: we love to see some pic
01:07 PM miss0r: and a video
01:07 PM gloops: everybody wants to know how to wire that breakout board up
01:08 PM IchGucksLive: gloops: as you wirer the second we are pros
01:08 PM IchGucksLive: but as people do not know anything thy paray for help
01:08 PM gloops: lol yes 2 months is a long time in cnc (2months since i couldnt do it)
01:08 PM IchGucksLive: as about 10000mashines build a wek
01:09 PM IchGucksLive: im off gn8
01:09 PM miss0r: hehe.
01:09 PM miss0r: nite
01:17 PM miss0r: gloops: I think I might end up building my own qctp.. but I can't seem to find a design I like. Can you recommend one... (design I like ~ something not too time comsuming to make, but still solid)
01:18 PM skunkworks: how big of a lathe?
01:19 PM miss0r: 300x1600mm lathe bed clearende x bed length
01:20 PM gregcnc: aren't Aloris clones common in Eu?
01:20 PM miss0r: Current toolpost is build for 25mm tooling
01:21 PM miss0r: That actualy looks stupid simple: http://watchmaking.weebly.com/uploads/1/1/7/9/1179986/7696268_orig.jpg
01:21 PM gregcnc: https://www.ebay.com/itm/281637827658
01:21 PM gloops: oh im no expert miss0r, i wonder of there are any diy designs on the web, must be a popular thing to try and make
01:22 PM * skunkworks would buy one.. Lots of fiddly bits..
01:22 PM gregcnc: I know multifix type are popular over there
01:22 PM skunkworks: we bought a cheap one for the compact 5 - very happy with it.
01:23 PM miss0r: I guess. I've never liked that design thou :)
01:23 PM miss0r: Its always felt unstable to me... Am I way off here?
01:23 PM miss0r: anyway - I would never go about making my own carriers for the multifix
01:24 PM gregcnc: I buy chinaco axa holders, they do fine
01:24 PM gregcnc: only real one I bought was Dorian for a cutoff blade
01:26 PM gloops: http://www.ebay.co.uk/itm/Boxford-Quick-Change-Toolpost-with-3-Standard-Holders-Ref-390202-From-Chrono/371943613089?
01:26 PM gloops: these are the best type
01:27 PM gloops: but a little more involved to make
01:28 PM miss0r: Is it just shiny metal, or are they using alu? :S
01:28 PM miss0r: ahh chronos...
01:28 PM miss0r: Metal then
01:29 PM gloops: yeah needs to be iron really
01:30 PM miss0r: yeah
01:30 PM miss0r: I have a few blocks of cast iron laying around here. The carriages will be made from steel naturaly
01:33 PM miss0r: I need to stop. I almost threw a block in the saw to start a poorly planned project right now on top of all the others. I will go have some family time while thinking about it. See you guys around
01:34 PM gloops: https://www.ebay.co.uk/itm/Dickson-type-Quick-Change-Tool-Holder/132361188918?
01:34 PM gloops: 45 notes per carrier ...you really have to have some work...or dont need work to pay for these
02:29 PM gregcnc: convert your bridgeport to 5 axis? https://www.ebay.com/itm/272902409656
02:34 PM gloops: but where is the code coming from?
03:05 PM CaptHindsight: Tom_L: was thinking about the low budget build using Chinaco parts...
03:06 PM CaptHindsight: Tom_L: since you have no way of knowing how well the parts will be until you get them there is no way to compare them or estimate how well they will work
03:06 PM CaptHindsight: Tom_L: that is the risk of buying Chinaco parts
03:07 PM gloops: lol!
03:07 PM CaptHindsight: Tom_L: and if you're low budget you can either try your luck on finding used or using ChinaCo
03:09 PM CaptHindsight: I buy parts when I am there so I can see what I'm buying
03:09 PM CaptHindsight: even then when I need more I risk not getting what I got the first time if I'm not standing right there
03:09 PM CaptHindsight: it took me a few years to build up some trust with a few suppliers
03:11 PM CaptHindsight: buying blindly from ebay or ali I've been surprised at times by getting great parts
03:11 PM CaptHindsight: other times just junk
03:12 PM CaptHindsight: even when buying ChinaCo parts locally I try to sort through their bins for good bearings without crunchiness or detents
03:12 PM Crom: Hmmm thinking of adding a radiant (ifrared) barrier on my roof joists on the bottom. I'm now wonder if I want to add a ridge vent, to vent all that heat from between the joists about the barrier
03:12 PM Crom: s/about/above/
03:14 PM CaptHindsight: you can try to guess that a 25mm square shaft might be stiffer than a 16mm round shaft but you don't know what bargain metal they used for either or..
03:15 PM CaptHindsight: how they hardened them for the batch you get
03:15 PM CaptHindsight: roundish bearings in the blocks vs dirt in the round bearings
03:16 PM CaptHindsight: they just keep on finding new ways to make a buck
03:17 PM CaptHindsight: and their philosophy is if you don't notice, care or say anything about a problem then it's not a problem
03:18 PM gloops: archivist - https://www.ebay.co.uk/itm/bearings/222689061580?
03:18 PM CaptHindsight: or if it costs you 50% of the sale price to ship them back to China
03:19 PM Crom: I still want to ungrade my 3040 to supported linear rails
03:19 PM CaptHindsight: Crom: what does it use now?
03:20 PM Crom: unsupported rod 16mm on the bottom for Y, 12mm for X and Z
03:20 PM CaptHindsight: Crom: round bar supported only at each end?
03:20 PM Crom: yep
03:22 PM Crom: Hence the .5mm to .8mm deflection
03:22 PM CaptHindsight: https://ibin.co/3e0n3WS5yLHy.jpg even this one uses 2 20mm for the Y
03:22 PM gregcnc: new cutting tool on the list https://www.youtube.com/watch?v=uK4hvcUxNFw
03:22 PM CaptHindsight: supported only at the ends
03:22 PM Crom: actually probably 2mm on Z/x
03:23 PM CaptHindsight: better pic https://imagebin.ca/v/3eSgPsli69h4
03:23 PM gloops: Crom - wood frame, 12mm sbr
03:23 PM CaptHindsight: ^^ 30 x 45 cm ChinaCo router
03:24 PM Crom: it's gonna wait until I CNC my HF 44991 X2
03:25 PM gloops: well you dont want the 8mm
03:25 PM gloops: that stuff is like meccano toys
03:25 PM Crom: then I can make a new X/Z plate for supported X and Z rails
03:25 PM gloops: you cant even buy bolts small enough to fit it
03:26 PM gloops: buy a stick welder Crom you can make a rigid machine then
03:27 PM CaptHindsight: for lots of hobby CNC users they will probably never notice the difference between using ChinaCo bearings and screws vs something quality made in the west...
03:27 PM CaptHindsight: they will most likely also be using cheap cutting tools and a spindle with cheap bearings ..
03:27 PM Crom: gloops, Too lazy right now... I actually have a 2.25" thick wall tube router, 36"x60", it's a polar machine I need to CNC
03:28 PM CaptHindsight: as well as not using the proper feeds and speeds
03:28 PM Crom: 2 pivots, 2 arms and a Z stage
03:28 PM CaptHindsight: a crappy vise or fixtures
03:29 PM CNCNeuie: Hallo ich möchte das CNC Interface (bei z.b. "MAGIG CNC Maschines") mit einem 64Bit Win10 an Mach3 verbinden mit einem "USB auf Parallel Adapter LPT" - aber das funktioniert nicht...???
03:29 PM gloops: well, i cant believe i didnt check the auctions for bearings, im stupider than a big bag of stupid things
03:29 PM gloops: £1 each
03:30 PM Crom: going to build ballscrew linear actuator to move the outer arm. Segment Chain gear to a jack shaft to a 12Nm closed loop stepper
03:30 PM gloops: Capt it doesnt matter for wood
03:30 PM Crom: for the inner arm.
03:31 PM gloops: what is this machine Crom - any pics or online comparison?
03:32 PM Crom: Gloops, I'll have pictures tomorrow. It's a Template follower router for mahing head stones.
03:33 PM CaptHindsight: gloops: maybe just for reliability, better parts will last longer
03:33 PM CaptHindsight: depends on just how crappy the Chinaco parts you get are
03:34 PM CaptHindsight: I once went through a box of bearings at Automation Technologies to get a set that didn't have detents
03:36 PM CaptHindsight: now I just buy stepper drives there, I just had too many problems with anything mechanical
03:36 PM CaptHindsight: oh an SBR for drawer slides and similar, not for a machine axis
03:37 PM gloops: thats where the money is Crom - granite
03:38 PM gloops: Capt well i suppose..but you can go through a lot of chinese bits before you accumulate the western price
03:38 PM JT-Shop: copy paste change 16 addresses over and over till my mouse finger hurts... a zillion left to do
03:39 PM gloops: you have got to apply a lot of force to bend an sbr rail, the bar is sitting in a groove
03:39 PM gloops: its basically the strength of the rail its mounted to
03:41 PM CaptHindsight: gloops: sure, depends on what you are cutting as well ..
03:42 PM CaptHindsight: wood, steel or alu and what finish you want
03:42 PM gloops: it probably isnt going to make any difference to wood, if you are anywhere round .05mm
03:42 PM gloops: even .1
03:43 PM gloops: joiners use rulers and tape measures, not micrometers
03:43 PM CaptHindsight: yeah wood deserves ChinaCo cutting tools
03:44 PM CaptHindsight: wood clogs up my coolant
03:44 PM gloops: what you cant live with is deflection and backlash
04:06 PM XXCoder: new restored goverment video https://youtu.be/_aVj7JSpSpU
04:10 PM XXCoder: 1936 man pretty old
04:12 PM CaptHindsight: pre-cnc but look at the bearings
04:12 PM XXCoder: manual lathe probably
04:13 PM CaptHindsight: yeah don't buy a crappy 1935 or earlier model :)
04:14 PM gloops: beautiful engineering
04:14 PM gloops: where did it all go wrong
04:14 PM gloops: its a few rubber bushes these days
04:14 PM CaptHindsight: unchecked crony capitalism
04:19 PM CaptHindsight: XXCoder: that vid brought up lots of other vids to interesting mechanisms
04:20 PM XXCoder: yeah american build videos
04:20 PM XXCoder: that specific one was recently restored. I just wish they'd apply anti-browning motion filter to it
04:20 PM XXCoder: so it dont move around
04:21 PM CaptHindsight: https://youtu.be/9sPi7DEbyI0?t=2m19s planetary gears in a tank
04:21 PM XXCoder: they burned a url into old video. jeez.\
04:22 PM XXCoder: did they themselves restore video?
04:23 PM XXCoder: https://www.youtube.com/watch?v=WC5BAp2xvDc
04:23 PM XXCoder: riveting
04:25 PM gloops: unfortunately our liberal masters decreed that relying on a skilled workforce was far too dangerous
04:25 PM XXCoder: lol
04:26 PM JT-Shop: XXCoder: doctor told me to eat more lean red meat and stop bleeding all over the place
04:26 PM CaptHindsight: JT-Shop: good advice, had the same issue
04:26 PM JT-Shop: low CBC?
04:27 PM XXCoder: CBC?
04:27 PM JT-Shop: Complete Blood Count
04:27 PM CaptHindsight: hemotologist wrote a paper about me since they didn't think a living person could have such low numbers
04:27 PM JT-Shop: my RBC was down to 13.2 and should not be below 14.0
04:27 PM CaptHindsight: HAH!
04:28 PM CaptHindsight: hematologist even
04:29 PM JT-Shop: I knew what you meant lol
04:29 PM JT-Shop: 24 of the 48 status rungs done... chicken time!
04:29 PM XXCoder: powered by writh eh ;)
04:30 PM XXCoder: oh JT-Shop my dehumidifier have extracted half cup of water so far
04:30 PM XXCoder: not a whole lot but then ita roomful of air.
04:30 PM XXCoder: windows is dry now
04:42 PM JT-Shop: does it show the humidity?
04:55 PM Deejay: gn8
04:58 PM Crom: JT my wifes was down to 11
04:59 PM Crom: That week she got 3 units of blood
05:05 PM JT-Shop: the doctor said a woman is usually lower than a man but didn't say how much
05:06 PM JT-Shop: 11 sounds very weak and can't get enough oxygen
05:08 PM Crom: She passed out twice
05:09 PM Tom_L: does time change this sunday?
05:10 PM Tom_L: i swear i heard that on the radio today
05:10 PM Crom: depends where you're at
05:10 PM Tom_L: 1st Sun in November
05:10 PM Tom_L: so it's not far away
05:11 PM Crom: Sunday Noveber 5th, next sunday, not this sunday
05:11 PM Tom_L: trying to figure out what to do for a mill table next
05:12 PM Tom_L: maybe a rectangular plate with threaded holes for now
05:12 PM Tom_L: JT-Shop did you see the plans i'm working on?
05:13 PM JT-Shop: no
05:13 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_idea1.jpg
05:14 PM Tom_L: need to figure out where to put the Y motor
05:14 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_idea.jpg
05:14 PM Tom_L: that was the other one using channel
05:19 PM Tom_L: didn't know Hardinge built bridgeports
05:32 PM sadisticroot: That's an odd design
05:33 PM sadisticroot: Looks very similar to the robots I have
05:33 PM sadisticroot: They have the X axis mounted to the Y on the bottom, and then the Z attached to that
05:38 PM Tom_L: odd?
05:38 PM Tom_L: most VMC are layed out that way
05:40 PM sadisticroot: Ah
05:41 PM sadisticroot: https://images.craigslist.org/00K0K_hhj6sJhnL4x_600x450.jpg
05:41 PM sadisticroot: The axis design is really similar
05:41 PM sadisticroot: https://images.craigslist.org/00K0K_hhj6sJhnL4x_1200x900.jpg bit bigger
05:44 PM Tom_L: where's the rest of it?
05:46 PM Tom_L: that looks like a pretty agressive ballscrew
05:47 PM sadisticroot: https://images.craigslist.org/00U0U_49lRDkBG89p_1200x900.jpg
05:49 PM sadisticroot: It is . . . move speed of 1000mm/sec
05:49 PM sadisticroot: (X/Y)
05:49 PM sadisticroot: 650mm/sec Z
05:49 PM JT-Shop: Tom_L: either one you need to add some pads that you can mill flat to fasten the linear rails to
05:50 PM sadisticroot: Looks like he did
05:50 PM Tom_L: one i did
05:50 PM Tom_L: thouht about milling the tube
05:52 PM JT-Shop: that could work if you have a thick enough wall
05:52 PM Tom_L: .179"
05:53 PM JT-Shop: ideally you weld it up then normalize it then machine it a tiny amount and hope it doesn't move lol
05:54 PM Tom_L: right
05:54 PM skunkworks_: real men use cast iron...
05:55 PM sadisticroot: The bases on this one are aluminum
05:55 PM sadisticroot: Pretty beefy though
06:11 PM sadisticroot: Time to head home
06:24 PM CaptHindsight: Tom_L: Sunday, November 5 in the USA
06:25 PM CaptHindsight: JT-Shop: heh, I was just under 4, talk about weak
06:26 PM JT-Shop: holy cow that is low
06:27 PM CaptHindsight: it's not uncommon for women in 3rd world areas to be that low after childbirth
06:27 PM CaptHindsight: I'm neither :)
06:29 PM JT-Shop: :)
06:34 PM JT-Shop: whew got the status ladder done 96 rungs 768 address changes my mouse finger is tired lol
07:00 PM MarcelineVQ: good lord :X
07:59 PM kanzure: CaptHindsight: can you stop by ##hplusroadmap for a few moments. have some questions about printhead overheating.
08:44 PM Vitran: Waiting for paint to dry. What is happening in the LinuxCNC world?
08:47 PM MarcelineVQ: waiting for part to arrive to know what other parts to get to wait for parts to arrive to assemble to make things that make parts to reduce waiting
08:47 PM Vitran: Sounds like Factorio
08:48 PM MarcelineVQ: that's a good analogy
08:48 PM Vitran: "Why are you making a railroad?" "To make things go faster"
08:49 PM malcom2073: Heh, love that game
09:30 PM evilroot: Blah
09:31 PM evilroot: I need to find better comps with real parallel ports
09:31 PM * evilroot reminds himself to head to surplus tomorrow
09:57 PM SpeedEvil: Is anyone aware of attempts to manufacture PCBs by not quite going all the way through the copper on a cutting process, and then etching?
09:57 PM SpeedEvil: to greatly reduce tool wear
09:59 PM evilroot: Nope
09:59 PM evilroot: The whole point of milling a board is for a quick one-off or small testing run
10:00 PM evilroot: Its inherently impractical
10:00 PM evilroot: Not going all the way through would then reduce the thickness on the rest of your board as well
10:01 PM evilroot: Same effect would be achieved by getting a board with thinner copper
10:01 PM evilroot: Also you'd saturate your etchant solution faster
10:02 PM evilroot: Personally I think milling PCBs is a bad idea period
10:03 PM evilroot: There are much better ways of producing a board on the simple and cheap. Toner transfer is the easiest and rivals almost any milled board
10:03 PM evilroot: Laser is what I use
10:04 PM evilroot: I just give a copper clad board a coast of spray paint and have the laser raster it off
10:04 PM evilroot: Etch, done
10:08 PM skunkworks_: I have seen the 3d printer crowd spray paint copper clad then scraping the paint off with a pin.
10:09 PM hazzy: SpeedEvil: I guess I could see that being effective if you coated the board with a resist before milling
10:09 PM hazzy: then you would be basically milling a mask and reducing the amount of material to be etched
10:15 PM CaptHindsight: copper ink and laser
10:17 PM CaptHindsight: applied with inkjet
10:19 PM CaptHindsight: SpeedEvil: did you mean milling the areas you want as an insulator thinner than the areas as a conductor and then etching lomh enough to just remove the thinner areas or??
10:19 PM CaptHindsight: lomh/long
10:19 PM SpeedEvil: yes
10:22 PM evilroot: Again, then why not just boards with thinner copper?
10:22 PM CaptHindsight: from my experience you'd have to agitate the etchant pretty well
10:23 PM CaptHindsight: it might not be thick enough for the current he needs
10:24 PM SpeedEvil: I was just idly wondering - it's likely a bad idea
10:24 PM CaptHindsight: is there a market for 1/4oz copper clad?
10:24 PM CaptHindsight: or 1/8oz for this?
10:25 PM CaptHindsight: low current and easily machined
10:26 PM CaptHindsight: how about copper plating over silver printed traces?
10:26 PM evilroot: SpeedEvil: it is a bad idea
10:26 PM evilroot: As you stated it
10:27 PM evilroot: Really doesn't yield any advantages
10:27 PM evilroot: From the start milling is about the worst possible method of making PCBs
10:28 PM evilroot: In terms of cost, time, resolution, etc
10:28 PM CaptHindsight: yet popular with hobbyists
10:29 PM evilroot: Because its a quick and dirty and simple way to make a single board
10:29 PM CaptHindsight: 1-2 layers, cheap and easy if you already have a cnc mill or router
10:29 PM evilroot: Exactly
10:29 PM evilroot: But it's for one-offs or at the most very small runs
10:29 PM CaptHindsight: no through plated holes
10:29 PM CaptHindsight: very common
10:30 PM CaptHindsight: many do it here for their interface boards on their cnc's
10:30 PM evilroot: If you want to make more than a dozen boards it costs so much less to make a simple UV table
10:30 PM CaptHindsight: some custom thing with a few parts
10:30 PM CaptHindsight: it's usually just one board
10:30 PM evilroot: Or send off for boards, which is crazy cheap now
10:30 PM evilroot: CaptHindsight: exactly
10:30 PM CaptHindsight: good fit for that
10:31 PM evilroot: So why try to cut costs for a process that's already horribly inefficient and basically a hack for a single board
10:36 PM CaptHindsight: nobody is talking about making several boards
10:36 PM CaptHindsight: he asked, let him try
10:37 PM CaptHindsight: go on with your life
10:37 PM CaptHindsight: is he drilling holes in your lifeboat or similar?
10:52 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/etching/etch1.jpg
10:53 PM Tom_L: agitating the etchant pretty well
10:53 PM Tom_L: can't see doing 2 processes to achieve one goal
10:53 PM Tom_L: with that, i'd just buy em from china nowdays
10:54 PM Tom_L: only takes ~10 min if you're in a big hurry for a prototype though
10:55 PM Tom_L: drilling holes is for the birds nowdays. just use smt
11:02 PM MarcelineVQ: smt is great, if you have a placer and reflower, that's no work for big humans :(
11:04 PM CaptHindsight: if everything is virtual you don't even have to make boards
11:06 PM Tom_L: i did a manual pick n place tube from a reverse fishtank pump
11:06 PM SpeedEvil: MarcelineVQ: https://www.youtube.com/watch?v=pdGSFc7VjBE
11:06 PM SpeedEvil: Some random hints for quick hand SMD assembly
11:07 PM SpeedEvil: Guy with actual pick and place machine that finds it much faster to actually just do it by hand for small runs.
11:07 PM SpeedEvil: With quite modest equipment
11:08 PM Tom_L: i use those little snap lid containers for the parts
11:10 PM Tom_itx: https://ae01.alicdn.com/kf/HTB1f2IQHVXXXXavXpXXq6xXFXXX8/DIY-font-b-SMD-b-font-SMT-Electronic-Component-Mini-font-b-Storage-b-font-font.jpg
11:10 PM Tom_L: that and the little suction tube makes it go quick
11:11 PM SpeedEvil: if you're doing a small run, leaving them on the tapes gives you a consistent orientation
11:11 PM CaptHindsight: when i was a kid...
11:11 PM CaptHindsight: we didn't have smt
11:11 PM Tom_L: mine was very similar to the one in the video
11:12 PM CaptHindsight: and tubes used sockets
11:12 PM CaptHindsight: no pcb, just solder directly from tube socket to tube socket
11:13 PM Tom_L: my luck, they usually popped out of the reel tape when i pulled it open
11:13 PM Tom_L: so i started using the boxes
11:14 PM SpeedEvil: Tom_L: theidea in the above video is to stick some doublesided tape down, put the tapes on that, then unpeel the film
11:15 PM CaptHindsight: that reminds me to get a pick-n-place working with LCNC
11:16 PM CaptHindsight: what did that openish project use for programming the motion?
11:17 PM CaptHindsight: https://github.com/openpnp/openpnp/wiki/Quick-Start
11:18 PM Tom_L: SpeedEvil no i never tried that
11:18 PM CaptHindsight: oooohh https://github.com/openpnp/openpnp/wiki/GcodeDriver
11:20 PM CaptHindsight: oh noes http://cohesion3d.com/cohesion3d-remix/
11:20 PM CaptHindsight: or smoothie
11:20 PM CaptHindsight: is there anything we can reuse from that project?
11:21 PM CaptHindsight: https://hackaday.io/project/9319-diy-pick-and-place
11:22 PM CaptHindsight: all they had to was use LCNC some g-code and do some HAL work
11:22 PM CaptHindsight: why all this avoid LCNC stuff?
11:22 PM Tom_L: how many intelligent vs non intelligent ppl do you meet in a day's time?
11:23 PM CaptHindsight: depends on where I spend mu day
11:24 PM CaptHindsight: Tom_L: smart enough to be a Java and xml wizard but can't read the LCNC wiki?
11:25 PM Tom_L: exactly the type
11:25 PM CaptHindsight: is it something like LCNC is for old people over 30?
11:26 PM * evilroot is 34
