12:06 AM miss0r: gah. Wrecking a part in the lathe on the final pass, because i am an idiot !
12:09 AM Wolf__: expensive for a mini itx
12:14 AM XXCoder: ow what happened?
01:57 AM IchGucksLive: XXCoder: i see DT solved the global warming issue as lower deth tolll on lower temps
01:57 AM fragalot: hello
01:57 AM XXCoder: what is "DT"
01:57 AM IchGucksLive: Donald
01:57 AM XXCoder: ah lol
01:58 AM IchGucksLive: cole and higher polution is the main reason for people not dieing in cold
01:58 AM IchGucksLive: fragalot: the Q man
01:59 AM IchGucksLive: did parts already arrive
01:59 AM XXCoder: that type of cold used to happen several times a year
01:59 AM XXCoder: not anymore. its exceptial now because its pretty rare now
02:00 AM IchGucksLive: snow in FL since 30years
02:00 AM Deejay: moin
02:00 AM IchGucksLive: ad for bathsuit makers
02:00 AM IchGucksLive: bad
02:01 AM fragalot: IchGucksLive: i think the steppers and drives are ready for pick-up
02:01 AM IchGucksLive: Deejay: ZweibrĂĽcken is sinking in water
02:02 AM fragalot: the rest will be for next week, or next month for some parts
02:02 AM IchGucksLive: fragalot: did you see my video on cabinet
02:02 AM fragalot: so i've started on a parametric CAD model yesterday evening on how it will all fit together...
02:03 AM fragalot: IchGucksLive: no? link?
02:03 AM IchGucksLive: https://www.youtube.com/watch?v=eRzqP_04t8c
02:04 AM IchGucksLive: but yours is better then mine ;-)
02:04 AM fragalot: not yet it isn't
02:06 AM fragalot: I want to get all the parts here to see how i'll organize the 5 power supplies, 3 drives, mesa, inrush limiters and relays
02:06 AM fragalot: and the vfd
02:07 AM fragalot: this should be a fun build :-)
02:07 AM IchGucksLive: take the VFD outside
02:08 AM IchGucksLive: outside mount to the cabinet
02:08 AM IchGucksLive: Why 5 Supplyes
02:08 AM IchGucksLive: a standard supply can easy run 2 steppers
02:08 AM fragalot: the VFD is not IP rated, so it will be inside of a cabinet
02:08 AM fragalot: IchGucksLive: 60V 6,6A power supplies
02:09 AM fragalot: the steppers take 6A each
02:09 AM IchGucksLive: 6A per phase is 3A on PSU
02:09 AM IchGucksLive: even lower
02:10 AM IchGucksLive: if you got Rotation Tables i combine 1liniar and 1 rot to one PSU
02:11 AM fragalot: Well then I have some power reserve, lol
02:11 AM IchGucksLive: and on 60V i guess you go for Hybrid this takes 110AC
02:11 AM fragalot: 240ac
02:11 AM fragalot: who in their right mind uses 110
02:11 AM fragalot: :p
02:11 AM IchGucksLive: so a simple 220-110 woudt give you a tiny part
02:12 AM IchGucksLive: space needed is 110x110x50mm
02:13 AM IchGucksLive: on U-rail
02:13 AM IchGucksLive: it takes 16A
02:13 AM IchGucksLive: so one for all
02:15 AM fragalot: i'm not sure I understand what you mean
02:28 AM IchGucksLive: im off
02:31 AM archivist: make a list of assertions, get a question and ignore it
02:31 AM MarcelineVQ: was hard to tell if he was assuming your psu's were 110v and the wall was 240 and suggesting a rail transformer or if he was suggesting a single rail component to power your drivers, not sure I'd just be putting 110v into a driver myself though, they usually come with ratings that let you know what's best for them after all.
02:33 AM archivist: he basically ignores what you have and states about stuff he has experience of
02:35 AM gloops: did this come as a complete set fragalot?
02:36 AM XXCoder: archivist: I rememebr when I was figuring what machine to build. he kept going to stuff way too big for my ponental machine
02:36 AM XXCoder: it was years ago but I still remember that oddity
02:36 AM gloops: or did the motors and drivers come paired - one snag to watch, a lot of drivers red light at 50v
02:37 AM archivist: dont think he has them yet
02:39 AM fragalot: MarcelineVQ: drives are rated for 80Vdc
02:39 AM fragalot: I haven't actually checked if they took AC
02:39 AM fragalot: AC24-80 DC30-110
02:40 AM fragalot: gloops: motor&drives were paired
02:40 AM fragalot: https://www.ebay.de/itm/DE-3-Set-8N-m-Nema34-116mm-Hybrid-Closed-Loop-Servo-Motor-6A-HSS86-Driver-CNC-/152850190031
02:41 AM fragalot: the post office opens in 20 minutes for me to go pick (I think) them up
02:41 AM gloops: they should be fine then
02:42 AM gloops: christmas morning again already lol
02:43 AM fragalot: :D
02:44 AM MarcelineVQ: beefy units :D
02:45 AM gloops: i think theyre right for 5mm screws on a metal cutting mill, smaller steppers would be limiting
02:45 AM MarcelineVQ: just depends how fast you want the job done hehe
02:46 AM gloops: im hoping i can cut sheet steel with 5mm screws and 3nm motors, maybe, slowly
02:47 AM fragalot: I want the cutter to eb able to reliably take a chip rather than rub
02:47 AM archivist: sharp cutters!
02:47 AM fragalot: and with a high speed spindle, it needs some beef to move it fast enough
02:48 AM fragalot: archivist: even the sharpest endmill doesn't stay sharp long if you let it rub
02:48 AM archivist: if the spindle is too fast the cutters could go blunt and rub
02:48 AM fragalot: the spindle should still have 1.2kW of power at 6000rpm
02:48 AM gloops: this all requires a rigid frame though, ive not found a deflection calculator for resin concrete
02:48 AM fragalot: which is alright for 6mm carbide
02:49 AM gloops: there are many formulas for it though online
02:49 AM fragalot: gloops: yeah it's unpredictable
02:49 AM fragalot: perhaps I should just get a hunk of 150mm tooling plate
02:49 AM fragalot: :P
02:55 AM gloops: 500mm x 200mm x 150mm aluminium, one end supported, 50kg = 0.0050170436mm
02:55 AM archivist: I am often using HSS and just a few hundred rpm
02:56 AM gloops: carbonfibre same section 0.0019510725mm
02:56 AM gloops: although carbonfibre might be stiffer than concrete
02:56 AM gloops: https://www.easycalculation.com/engineering/mechanical/deflection-solid-rectangular-beams.php
02:59 AM gloops: to join the ally would need plenty of bolts, and some torque
03:00 AM gloops: which will serve to throw alignment out slightly
03:02 AM fragalot: archivist: I do too on my manual mill, but i've found that actually sticking to the endmill manufacturers' recommended feeds & speeds really prolongs life
03:03 AM fragalot: gloops: Aye.
03:03 AM archivist: I am not using endmills all the time, gear cutters and home ground specials
03:04 AM fragalot: then run it at whatever speed gives a good chip & no chatter :P
03:05 AM fragalot: which, on an RF45, is pretty darn difficult
03:05 AM fragalot: it has a real hatred towards facemills over 40mm in size
03:05 AM fragalot: but it runs flycutters just fine
03:06 AM archivist: your high speed spindle wont like facemills :)
03:07 AM archivist: I have not used a facemill for a long time
03:07 AM fragalot: I don't expect it to, that's why its on a CNC and not a manual mill ;D
03:11 AM gloops: would be capable of high speed aluminium work id guess, with a good coolant system
03:11 AM fragalot: should do
03:11 AM XXCoder: archivist: could use facemill as fly cutter with just one insert
03:11 AM fragalot: or engraving if I want it to. Makes it nice & universal
03:12 AM XXCoder: higfh rpm helps in this case. just dont try to cut too much'
03:16 AM gloops: high performance endmill - watch that cut https://www.youtube.com/watch?v=8hze0A7p5oU
03:17 AM gloops: like cutting a block of cheese!
03:18 AM fragalot: gloops: look up "HSM" or high speed machining
03:18 AM fragalot: gloops: https://www.youtube.com/watch?v=ZrSe0zyZm8w&
03:19 AM gloops: 302m/min lol
03:20 AM fragalot: the best thing abough HSM is that it's done dry
03:20 AM fragalot: no mess, all you need to do to clean up is pick the chips out of the drywall
03:24 AM archivist: the new owner of mach gave a talk and mentioned why carbide cutters break, micro cracks due to the hot cold of the coolant, they last better hot
03:25 AM fragalot: yup
03:25 AM fragalot: that's why you get coated ones.. carbide doesn't need cooling as it doesn't lose it's temper, but it does help if it's lubricated
03:27 AM fragalot: anyway i'm off to the post office
03:27 AM fragalot: ttyl
03:49 AM fragalot: not what I expected
03:49 AM MarcelineVQ: smaller than you thought?
03:50 AM fragalot: no different package
03:50 AM fragalot: :P
03:50 AM MarcelineVQ: Is it what you payed for though :X
03:50 AM fragalot: yeah it was a box of scalpel blades
03:54 AM archivist: I am still in stock of scalpel blades, from the 1980's when I did tape up PCB design
04:48 AM jthornton: morning
04:49 AM fragalot: morning
04:50 AM fragalot: what's the best way to attach the gantry on an E/G mill, as I don't think it's a good idea to try and cast the entire thing in one go
04:50 AM jthornton: what's an E/G mill?
04:51 AM archivist: epoxy granite methinks
04:52 AM fragalot: ^
04:52 AM jthornton: ah that makes sense then
04:53 AM fragalot: should i cast in a few tie-rods in the gantry portion, or is it better to provide some sort of hollow shaft for a rod to slide through the entire assembly after?
04:54 AM jthornton: your going to cast the gantry?
04:54 AM archivist: depends!
04:54 AM fragalot: jthornton: I don't know.
04:54 AM fragalot: the gantry will be fixed
04:54 AM fragalot: so I don't see an issue in doing so.
04:55 AM jthornton: the gantry is just the YZ axes?
04:56 AM jthornton: got some drawings of the design?
04:57 AM fragalot: jthornton: working on 'm now.. it will basically be a beefed up version of this https://cdn.hackaday.io/files/18955810970720/CNC%20Mill%20Epoxy%20Granite.jpg
05:01 AM archivist: or cast the gantry and base together
05:01 AM jthornton: interesting design
05:01 AM fragalot: archivist: no idea if I can guarantee a good pour that large in one go :/
05:01 AM fragalot: plus i'll never be able to flip it over :P
05:01 AM archivist: crane
05:02 AM * jthornton has never done epoxy granite so I'll just have to watch
05:05 AM archivist: jack and pack
05:05 AM fragalot: can I guarantee there won't be any voids on a mold that large though?
05:06 AM fragalot: the larger it is, the more difficult to vibrate the mass
05:06 AM fragalot: and with the hollow portion in it, how do i guarantee there's sufficient material in the undercuts?
05:07 AM fragalot: this actually looks a lot more like what I had in mind, https://i.imgur.com/Isu6qsc.jpg
05:08 AM syyl: see, theres a small german company making a machine like that in epoxy-concrete
05:08 AM syyl: https://www.cnc-technik-mueller.de/fs3mg-mineralgussmaschine/
05:09 AM jthornton: that one looks more proportionally correct almost to the golden ratio
05:10 AM fragalot: There is no substitute for stubby mass. :P
05:11 AM jthornton: fragalot: the second photo looks better
05:14 AM jthornton: but a bit short on Z
05:14 AM jthornton: the cnc-technik looks like a good ZYX travel
05:15 AM fragalot: I currently have 750, 550 and 400mm rails to work with
05:16 AM archivist: I had to extend my Z because of the rotaries and things like drill chucks
05:17 AM fragalot: yeah those take up space quick, lol
05:18 AM archivist: I started out with 60x90mm travel xy, way too small
05:20 AM malcom2073: That is tiny
05:21 AM archivist: when most work is rotate and a 2mm cut that seems large
05:22 AM malcom2073: tiny gears?
05:22 AM archivist: when getting tooling in range it is small
05:22 AM archivist: clock gears
05:22 AM archivist: for a larger dia just hang the rotary off the side
05:23 AM fragalot: so.. no using high pressure cooling jets then or you'll warp the parts? :P
05:45 AM archivist: part heating rarely bothers me, i cut slowly with light cuts
05:46 AM gloops: a 1 piece cast might be possible if it was poured with the back of the machine, the vertical side, as the open face of the mold
05:48 AM gloops: to get something with any kind of complex contours or details you would need to make a plug first, then take a mold off that, before casting the part
05:49 AM jthornton: have you watched any of myfordboy's casting videos?
05:49 AM gloops: with the mold in multiple parts, that would take some time
05:49 AM jthornton: might give you an idea or two
05:49 AM gloops: no not seen them
06:05 AM jthornton: he makes some pretty neat plugs for casting aluminum parts
06:08 AM archivist: pattern making http://www.collection.archivist.info/searchv13.php?searchstr=BK170
06:44 AM phipli: morning
06:44 AM jthornton: morning
06:50 AM jthornton: I got another RPi to mess with and playing with a USB camera now and have a RPi NoIR camera on the way
06:55 AM jthornton: two pullets in the nest box and one waiting outside
06:59 AM andypugh: RPi + Camera + 3D Printer + OctoPi is handy.
06:59 AM jthornton: OctoPi?
07:00 AM andypugh: Octoprint image for Pi
07:00 AM jthornton: ah
07:41 AM Tom_L: 17°F
07:42 AM Tom_L: hi 43
07:44 AM jthornton: 17°F to 26°F here
07:47 AM phipli: jthornton + others : how you coping with the weather?
07:47 AM jthornton: burning lots of firewood, chickens don't seem to mind 1°F
07:48 AM phipli: RRR's are tough birds - yours are half RRR aren't they?
07:49 AM andypugh: +5 C here (that’s about 40F?)
07:50 AM phipli: andypugh, we need a temperature conversion bot :)
07:50 AM jthornton: the pullets are all RIR
07:50 AM phipli: or a more general unit converter :)
07:50 AM andypugh: Due to fly to Lapland on Monday. It’s not cold there either. About -6 when we want -30.
07:50 AM jthornton: the rooster is about to get a name change to Coq au Vin
07:51 AM phipli: jthornton, oh dear
07:51 AM phipli: is he in trouble?
07:51 AM andypugh: Or just looking delicious?
07:51 AM jthornton: he's very aggressive to people
07:51 AM phipli: yourself included?
07:52 AM phipli: cockerels often are
07:52 AM jthornton: he knows I'm the head chicken but will do the chicken kick boxing to everyone else
07:52 AM phipli: one attacked my girlfriend's grandfather once
07:52 AM phipli: he had matches in his pocket...
07:52 AM phipli: the bird managed to set fire to him
07:52 AM jthornton: damn
07:53 AM phipli: it didn't see sunset
07:53 AM jthornton: I don't need a rooster and was out of my mind when I ordered one
07:53 AM jthornton: https://www.cacklehatchery.com/golden-comet.html
07:53 AM phipli: lol
07:53 AM phipli: change of plan :s
07:53 AM jthornton: https://www.cacklehatchery.com/cinnamon-queens.html
07:54 AM jthornton: I'm thinking of getting a couple of each one of those prolific egg layers in the spring
07:54 AM phipli: watch mixing new flocks
07:54 AM phipli: ours still haven't settled after 6 months
07:54 AM phipli: one of the birds still gives the new ones a hard time
07:54 AM jthornton: the first Barred Rock cockerel was very gentle and nice
07:54 AM phipli: and it has made it a lot harder to bond with the new birds
07:55 AM jthornton: I have one that goes behind a curtain at night too roost
07:55 AM jthornton: to roost
07:55 AM phipli: one of the hens?
07:56 AM jthornton: yes, she was picking on the neighbor hens on the roost so I put up a curtain and placed her behind it a few times and now it's her spot
07:56 AM phipli: one of ours just wont leave them alone all day
07:57 AM phipli: any time she sees them eating she runs over and wacks them
07:57 AM phipli: little madam
07:57 AM andypugh: Browsing the site: You need a peacock.
07:57 AM phipli: andypugh, NO!
07:57 AM phipli: bloody things
07:57 AM phipli: they sit on the roof and shout at ungodly hours
08:00 AM jthornton: https://imagebin.ca/v/3nGmrR8prtM7
08:00 AM MarcelineVQ: they are really quite loud but that's not their real problem, their shit is unreal awful to get off things
08:01 AM phipli: heh
08:01 AM phipli: do you have some?
08:01 AM MarcelineVQ: We had a lot, then we had a hunter, now we don't
08:01 AM phipli: jthornton, nice - that your camera stream?
08:01 AM MarcelineVQ: And by a lot I mean more than 20
08:01 AM jthornton: one of my IP cameras
08:02 AM phipli: MarcelineVQ, did you keep them for eggs? Or aesthetic reasons?
08:03 AM MarcelineVQ: They were already on the property when we got here being a nuisance
08:03 AM MarcelineVQ: There was turkey's too but they're quite nice, the females anyway, the males chase cars and are generally retarded
08:04 AM MarcelineVQ: The turkeys managed to get rid of themselves over time which is too bad, had females that would come around just to raise chicks and then leave
08:05 AM phipli: Yeah - the missus would like turkeys
08:05 AM phipli: the people with that youtube pig have got one now
08:05 AM MarcelineVQ: turkey males are hideous things even when they have good attitudes
08:05 AM phipli: it gets envious when the pig gets too much attention and looks for hugs
08:05 AM phipli: heh
08:05 AM MarcelineVQ: it looks unconmfortable to be alive as a male turkey, I'm not surprised they act like they do
08:06 AM phipli: MarcelineVQ, jthornton sounds like he's having enough trouble with the cockerel
08:06 AM phipli: we've never kept any male livestock
08:06 AM phipli: the goat was female (males stink)
08:07 AM phipli: and we've only ever had hens
08:08 AM phipli: hum
08:09 AM phipli: anyone use opensource tools for resource / time management?
08:09 AM phipli: specifically for checking where you / staff have spent their time to help with billing clients when you have concurrent jobs?
08:09 AM jthornton: nope
08:10 AM jthornton: I'm the staff lol
08:10 AM phipli: :)
08:10 AM jthornton: got 3 steady layers and I see another one in the nest box
08:11 AM phipli: Eggs for breakfast?
08:11 AM MarcelineVQ: I use rainlendar but it doesn't fit the requirements you're after afaik
08:11 AM MarcelineVQ: it's pretty much just a task calendar
08:12 AM phipli: so designed for planning in work?
08:12 AM jthornton: lol granddaughter had her first taste of eggs yesterday and made her mom cook three helpings
08:12 AM phipli: eggcellent :)
08:12 AM jthornton: she ate all the eggs I had left
08:13 AM phipli: :)
08:13 AM phipli: Our production is back up now that they're laying again so I'll be bringing lots more into work
08:13 AM jthornton: they are still small eggs, 42g-44g
08:13 AM MarcelineVQ: I'd categorise it as a replacment for google calendar more than anything you'd probably want to have for work. I did hear of something recently for team stuff, wonder if I could find it
08:13 AM phipli: makes my colleagues happy
08:14 AM jthornton: the cockerel won't be worth eating as he is all bruised up I imagine...
08:15 AM MarcelineVQ: oh it was Telegram, which is for team communication not management :X Well that's not especially helpful. it's a pretty interesting thing though https://telegram.org/faq
08:16 AM phipli: jthornton, what did he do?
08:16 AM phipli: I've heard of telegram... but can't remember where
08:17 AM jthornton: he just attacked me again... a boot then back him up around the yard
08:17 AM jthornton: he will be too dangerous when he has spurs
08:17 AM phipli: what were you doing at the time?
08:18 AM phipli: some get really grumpy if you pick up a chicken
08:18 AM phipli: others don't like you in the enclosure...
08:18 AM phipli: others are just mental
08:18 AM jthornton: he is just mental lol
08:18 AM phipli: used to know a duck that attacked anybody it saw on sight
08:18 AM phipli: head down, charge
08:18 AM jthornton: I was just putting a bucket to hold the door open
08:18 AM phipli: pecked hard enough to break the skin
08:19 AM jthornton: dang that is pretty hard for a duck I'd imagine
08:19 AM MarcelineVQ: idk, ducks are really hardcore
08:19 AM MarcelineVQ: like, loco
08:19 AM jthornton: lol
08:20 AM jthornton: I guess I had some thoughts of a rooster protecting the flock or some other nonsense at the time I ordered them
08:21 AM phipli: some are fine
08:21 AM phipli: lol - just realised I said we only had hens
08:21 AM phipli: I forgot about the cockerel we had
08:21 AM jthornton: yea the first one I had was very friendly
08:21 AM phipli: because it was really tame
08:21 AM phipli: basically bottom of the pecking order
08:22 AM phipli: literally hen pecked
08:22 AM * jthornton needs to start some fires out in the shop and garage
08:27 AM JT-Shop: I mix about 10% of wood ash in with the dirt for their dust bath
08:28 AM phipli: I need a bigger run so I can stand in it
08:28 AM phipli: don't like what we have - fine for birds, but really difficult to work with as a human
08:29 AM JT-Shop: yea, my first one was the same problem too short for me lol
08:30 AM JT-Shop: hmm, I think I'm getting a 4th egg today
08:40 AM archivist: egg producer code printer, just been asked for one/ or make
08:42 AM thochguertel_ is now known as thochguertel
08:55 AM IchGucksLive: hi
08:56 AM gloops: hello
08:56 AM IchGucksLive: water levels are slightly falling
08:56 AM gloops: if ever i took any advice you gave Ichs, it should have been - use aluminium extrusions for building
08:57 AM IchGucksLive: why
08:57 AM gloops: getting to the bottom of the steel pile and im sick of this project haha, every small step is taking ages niw
08:57 AM IchGucksLive: you did well
08:58 AM gloops: could have made this in a week with ally
08:58 AM IchGucksLive: AL profile is just 2hr of sewing
08:58 AM IchGucksLive: screwing
08:58 AM IchGucksLive: even woodframe is only that way
08:58 AM gloops: yeah wood would have been a lot easier
08:58 AM IchGucksLive: the distrobutr does the rest for you
08:59 AM IchGucksLive: Homedepo got precise sawing
08:59 AM IchGucksLive: or my tecwaker profile supply
09:00 AM gloops: well i went with steel now so got to be finished
09:00 AM IchGucksLive: its a better mashine at the end
09:01 AM gloops: maybe yes
09:12 AM phipli: hum
09:12 AM phipli: latest chicken door program fits in ~4k
09:12 AM phipli: might just load it into an ATMega8
09:12 AM phipli: because they're cheap
09:13 AM IchGucksLive: DCF77 and Sunlight control ?
09:14 AM phipli: RTC and fixed open / close time
09:15 AM phipli: DCF77 is a german thing - can I even pick it up over here?
09:15 AM phipli: heh
09:15 AM phipli: because it is longwave, you can
09:15 AM phipli: https://en.wikipedia.org/wiki/DCF77#/media/File:Dcf_weite.jpg
09:16 AM IchGucksLive: its just a pice of cupper and a tiny steel bar
09:17 AM phipli: what is the transmission? just a steady pulse?
09:17 AM phipli: or is it an encoded time signal?
09:17 AM IchGucksLive: pulse sequence over 1min
09:19 AM archivist: dcf is not that good here
09:24 AM phipli: interesting system
09:24 AM phipli: even broadcasts a weather report
09:25 AM phipli: says they're planning to up the power at some point
09:25 AM archivist: the british version was at Rugby but has moved
09:26 AM phipli: yeah
09:26 AM phipli: the peeps before the radio 4 news
09:26 AM phipli: does that contain data too?
09:26 AM phipli: https://en.wikipedia.org/wiki/Time_from_NPL_(MSF)
09:26 AM archivist: long time since I looked
09:27 AM phipli: yeah
09:27 AM phipli: does
09:28 AM phipli: no weather though :)
09:28 AM sync: yeah dcf has weather data encoded in it
09:28 AM sync: with crappy DES encryption
09:47 AM dioz_ is now known as dioz
09:51 AM andypugh: I used MSF for a fum project.
09:51 AM andypugh: (fun project)
09:52 AM andypugh: http://bodgesoc.blogspot.co.uk/2015/09/clock.html
10:02 AM phipli: nice
10:02 AM phipli: they converted the clock in the building next to my work
10:02 AM dioz: yo
10:02 AM phipli: if the clock gets ahead for any reason
10:02 AM dioz: any of you old men know how to use fusion 360?
10:03 AM phipli: it has to go right around the 12 hours and chimes every one
10:03 AM Tom_L: dioz some of the rest of us might
10:03 AM dioz: Tom_L: how did you learn to use it?
10:04 AM Tom_L: i didn't say i was one of them
10:04 AM Tom_L: i use solidworks, catia and smartcam
10:04 AM andypugh: I know how to use Fusion 360. But I am only middle-aged. (assuming I live to 150 and life is svided into three equally sized ages)
10:04 AM Tom_L: watching the threads here, i'm not sure i plan to learn it
10:05 AM jdh: too old?
10:06 AM Tom_L: andypugh how do the old timers feel about using an arduino on the clock?
10:06 AM phipli: if it was in the students union, they might have not got a look-in
10:06 AM andypugh: Most of them don’t know anything about it. They just know that the clock works again
10:06 AM Tom_L: heh, probably best left that way..
10:07 AM phipli: how reliable has it been?
10:07 AM andypugh: Fairly. It’s run for a few years now
10:08 AM andypugh: Since September 2015 in fact.
10:08 AM andypugh: So t has dealt with a few summer time switches.
10:09 AM phipli: I ran a raspberry pi for 3 years... but then I moved house
10:09 AM phipli: sat here wishing that the relays in front of me had standard 0.1" spaced pins...
10:10 AM phipli: How exactly did you voltage regulate? something like a 7805?
10:11 AM Tom_L: smps are nearly as cheap
10:12 AM phipli: smps?
10:13 AM andypugh: I didn’t trust an SMPS to run long enough.
10:13 AM phipli: ah, switch-mode
10:13 AM phipli: I thought the s was for plural
10:14 AM andypugh: I have a very over-rated linear regulator under the vero-board circuit.
10:25 AM Tom_L: morning pete
10:37 AM sync: andypugh: with non shitty components they run fairly long
10:37 AM andypugh: Yes, but the good ones are super-expensive
10:39 AM Tom_L: got it on a surge protector so when lightening strikes at 10:04 p.m. on 11/12 it'll be ok?
10:42 AM andypugh: No, I am just hoping for the best there
10:43 AM phipli: do you still have access to it, or is it entirely someone else's problem now?
10:44 AM andypugh: I still have access, and keep an eye on it.
10:44 AM andypugh: Acopian claim 100,000 hours MTBF for their power supplies.
10:45 AM andypugh: But that is only 10 years.
10:47 AM phipli: something like a TVS might help with surges - or some kind of polyfuse
10:48 AM phipli: or, if you have access, you could fix it when the 1:1000000000000 even happens
10:48 AM phipli: *ervent
10:48 AM phipli: *event
11:03 AM gloops: you can do exactly the same by combining freecad, inkscape, gimp, meshlab, and heekscnc as you can in Fusion 360
11:06 AM Tom_L: that's alot of programs to learn just to spit out a little bit of gcode
11:07 AM gloops: was joking, well half joking heh
11:08 AM Tom_L: linux needs a 'one and done' solution
11:08 AM gloops: freecad is looking like it would cover a lot of basic milling jobs now
11:09 AM gloops: linuxcnc should poach the bloke whos working on the BlenderCAM project single handed
11:13 AM andypugh: There are at least two working in it, but not very much recently: https://github.com/vilemduha/blendercam/graphs/contributors
11:14 AM gloops: ahh thought it was only the one andypugh, i keep having a look at it now and again, odd posts here and there, seems only 1 guy has done any tutorials or documentation last time i look, on youtube
11:15 AM andypugh: The guys doing tutorials and docs are not always the ones working on the projects.
11:16 AM andypugh: I did some docs for STMBL, but haven’t really worked on the hardware or code.
11:19 AM gloops: well, i suppose if someone joins a project who has done similar things before it moves pretty quick, to get a basic framework running anyway, suppose its down to what others are prepared to do the finishing off and docs and so on
11:32 AM phipli: AVR_atmega_HV_doctor++
11:39 AM phipli: if any of you program stand alone AVR chips, you might be interested this board
11:39 AM phipli: it is a high voltage programmer that resets a chip to generic settings
11:39 AM phipli: great if you've bricked it, or if you're trying to program a chip for the first time, without a crystal (internal clock)
11:40 AM phipli: plug the chip in, power it up and you get a go / no-go led result
11:42 AM phipli: https://www.ebay.com/itm/152277809800
11:42 AM phipli: seems to have been slightly revised since mine (couple of extra sockets)
11:42 AM phipli: but useful if you play with AVRs
12:02 PM JT-Shop: phipli: I'm making a nest camera with the pi and pi camera and using a POE splitter to get power to the pi
12:09 PM IchGucksLive: hi
12:11 PM JT-Shop: I need to figure out how to connect a ir light to the pi
12:12 PM Deejay: with wire!
12:14 PM JT-Shop: https://imagebin.ca/v/3nI1WxMhUSTP
12:14 PM JT-Shop: hmm maybe I don't need more light
12:15 PM Tom_L: looks fine from my vantage point
12:15 PM gloops: growlight with 600 watt ballast and sodium bulb
12:15 PM Tom_L: you want baked chicken?
12:15 PM phipli: JT-Shop, what kind of power light are you looking at? What sort of distance?
12:16 PM JT-Shop: look at the link, maybe I don't need one
12:16 PM phipli: if it is only in a nest box, you could just use a couple of IR leds and drive them off the 5v power rail?
12:16 PM JT-Shop: that's the inside of the nest box
12:16 PM JT-Shop: yea
12:17 PM JT-Shop: that's the usb camera that I have now
12:17 PM gloops: i put one in my greenhouse without any covers or shading, only testing it i left it on one night, neighbour over the back asked me what the lovely light was the next day, filled the area with a lovely pink glow she said haha
12:17 PM phipli: if you don't need to see at night that looks fine :)
12:17 PM phipli: gloops, heh
12:17 PM JT-Shop: yea, just need to move it down a bit
12:18 PM JT-Shop: I just want to try and figure out who is laying
12:18 PM JT-Shop: without having to do the butt check
12:46 PM phipli: heh
01:12 PM phipli: any advice on 7805 capacitors?
01:13 PM phipli: Datasheet says 330nF input, 100nF output
01:13 PM phipli: but I don't have any 330nF caps of any type
01:13 PM phipli: closest I have is 220nF
01:15 PM phipli: 100nF + 220nF in parallel?
01:20 PM Deejay: and ten!
01:22 PM phipli: hum?
01:29 PM JT-Shop: teaching the granddaughter archery :)
01:30 PM Deejay: 100nF + 220nF + 10nF = 330nF... or not?
01:30 PM Deejay: JT-Shop, dont shoot at the chickens!
01:30 PM DaViruz: is
01:30 PM phipli: ah right
01:30 PM phipli: Deejay, I was thinking it was close enough
01:31 PM phipli: 3% error
01:31 PM Deejay: yeah, probably it will :)
01:31 PM phipli: as long as you didn't mean 10F :)
01:31 PM phipli: JT-Shop, poor cockerel
01:37 PM JT-Shop: lol
01:38 PM pcw_home: usually the more the merrier on bypasses (so 2X or 5X will not hurt )
01:43 PM miss0r: Why wait for china when you can make your own C7 ER11 collect with a 100mm shank, and 3.5mm through spindle coolant channal ? :)
01:43 PM MrHindsight: Deejay: caps in parallel, just add their values
01:43 PM miss0r: Just completed it, I am pleased
01:44 PM MrHindsight: Deejay: https://www.allaboutcircuits.com/textbook/direct-current/chpt-13/series-and-parallel-capacitors/
01:45 PM MrHindsight: miss0r: the drilling worked on the lathe?
01:47 PM miss0r: MrHindsight: yeah, I ended up going in from both ends with a regular HSS drill. it lined up _perfectly_, even with peck drilling
01:49 PM miss0r: I have have 0.007mm runout at the spindle nose, Quite pleased with that, considering I didn't use a grinder. it is all turned
01:52 PM JT-Shop: starting sunday no more freezing nights for a few days :)
01:53 PM miss0r: good for the heating bill
01:54 PM JT-Shop: and firewood
01:55 PM JT-Shop: I've been burning it like crazy
01:56 PM andypugh: miss0r: Years ago I was so pleased with this that I took photos: https://photos.app.goo.gl/mbAZ5SpIF8a7Qqvm2 and https://photos.app.goo.gl/GxSB8K0KjK0AjNXG2 (not very good photos, I grant you).
01:57 PM andypugh: Not very impressive if done with a lathe, but I did it with a hand-held pistol drill.
01:57 PM miss0r: andypugh: What was the application ? :)
01:57 PM miss0r: That was handdrilled ? damn
01:57 PM andypugh: I actually can’t remember what it was for.
01:58 PM miss0r: Doesn't matter. That is a pretty good job for a handheld drill, i'll give you that
02:00 PM andypugh: In other news, my attempts to make tapers have gone a _lot_ better now that I have realised that a 7/24 taper (like BT30, CAT40 etc) is not at an angle of (Arctan(7/24))/2 but is actually Arctan(7/48)
02:01 PM miss0r: I guess that helps ;)
02:02 PM andypugh: ie 8.2971 degrees not 8.1301 degrees. (the wrong calculation is close enough to blame machine / workmanship )
02:02 PM MrHindsight: 11F now, we should finally be above freezing by Monday
02:04 PM MrHindsight: andypugh: did you get your exoskeleton yet?
02:04 PM MrHindsight: https://media.ford.com/content/fordmedia/fna/us/en/news/2017/11/09/ford-exoskeleton-technology-pilot.html
02:04 PM andypugh: I made an adaptor last night for my lathe (Stub MT4.5 spindle taper) to BT / ISO - 30 for machining mill spindle tooling. (And, initially, to make a new drive adaptor for the vertical head, which is worn and cracked)
02:05 PM andypugh: MrHindsight: That’s an interesting idea. But really it would need some pumps too to prevent the “empty arm” eddect.
02:05 PM andypugh: (effect)
02:08 PM MrHindsight: another down side (depending on perspective) is it it tracks the positions of the users
02:08 PM MrHindsight: it/if
02:08 PM gloops: i guess those will go the way of mobility scooters, initially for old people who have trouble walking - now mainly used by people who can walk but prefer to avoid the unpleasant experience of doing so
02:08 PM MrHindsight: train the replacement robot
02:09 PM MrHindsight: gloops: walking while sleeping could be useful
02:09 PM andypugh: The device is suitable for workers 5 feet to 6 feet 4. That would be a rubbish job for someone 5 feet tall. (if you watch the video)
02:11 PM gloops: MrHindsight walking and many other things, no point in being conscious for a lot of things humans do
02:12 PM gloops: in fact, i dont suppose anyone knows the point of being conscious at all
02:12 PM fragalot: 'sup
02:12 PM MrHindsight: it's highly over rated
02:14 PM JT-Shop: I need a 16C collet chuck for the samson
02:48 PM JimPanski: Hi Folks! Is there any chance to add inputs to an existing classicladder project?
02:50 PM Tom_shop: i would think so but i don't use CL
02:51 PM Crom: Found a Mini-ITX N3150 fanless motherboard on Amazon passmark 3200ish speed... Think I'm going to build new computers out of those
02:51 PM Crom: and they support up to 16GB of RAM, though I think I'm only going to install 8GB in them
02:55 PM JT-Shop: JimPanski: sure, are you out of inputs?
02:56 PM JimPanski: yes, all the 15 are used
02:56 PM JT-Shop: http://linuxcnc.org/docs/2.7/html/ladder/classic-ladder.html#_realtime_module
02:57 PM JT-Shop: numPhysInputs
02:59 PM JimPanski: awesome... it worked..thank you very much
02:59 PM JT-Shop: np
03:08 PM miss0r: So this is what it looks like now, with the homemade ER11 collect in it: https://imgur.com/a/Hc5jR
03:09 PM miss0r: MrHindsight fragalot
03:09 PM JT-Shop: that your Z axis?
03:10 PM fragalot: miss0r: I take it your venture was a success then?
03:10 PM miss0r: (I know I know) the thread on the ER11 is utterly crummy. but I didn't notice the cutter was dull till it was too late
03:10 PM miss0r: JT-Shop: for my EDM, yes
03:10 PM gloops: ebay - $36000
03:11 PM miss0r: fragalot Indeed it was :) I didn't have time until now to finish it
03:11 PM miss0r: I have measured 0.007mm runout at the spindle nose. The inside of the ER11 is not as perfect - that will need to be ground in place
03:12 PM miss0r: gloops: What did you find there?
03:12 PM fragalot: miss0r: will you be grinding the nut in too,
03:12 PM miss0r: no, theres plenty slob in that
03:13 PM fragalot: k
03:13 PM miss0r: (it originates from a generic chinesium ER11 collect)
03:13 PM gloops: miss0r i mean put the edm on ebay
03:13 PM miss0r: gloops: NO! :]
03:13 PM fragalot: gloops: why would he?
03:13 PM fragalot: build a crappier one, and put the crappy one on ebay instead
03:13 PM fragalot: :P
03:13 PM miss0r: Only if people find a way to do a paypal transfer of blood, sweat & tears
03:13 PM gloops: can always make another
03:14 PM miss0r: lol - This has taken plenty of time. I can assure you, it will not be feesable
03:14 PM miss0r: (spell check...)
03:15 PM * fragalot really dislikes fusion360 for assemblies
03:15 PM fragalot: nothing like the software i'm used to >.<
03:15 PM miss0r: fragalot I can take a picture of the ER11 collect, should you be interrested?
03:15 PM jensor: I just downloaded a python script. But axis apparently open it. Any suggestions on this?
03:15 PM fragalot: miss0r: I am.
03:15 PM gregcnc_: impressive mix of hex, hex socket, cross and slotted head screws
03:15 PM fragalot: jensor: run it via the terminal instead?
03:15 PM jensor: ok I'll try that
03:15 PM fragalot: gregcnc_: no canadian square?
03:16 PM gregcnc_: miss0r did you manage a torx somewhere?
03:16 PM gloops: https://www.ebay.co.uk/itm/Broken-Tap-and-Bolt-Disintergrator/263384234312?
03:16 PM fragalot: oh, you meant miss0r's spindle xD
03:17 PM fragalot: I especially like the recessed hex heads
03:18 PM miss0r: gregcnc_. yeah. I ran out of the correct size of alot of stuff during the build ;)
03:18 PM miss0r: lol
03:19 PM jensor: Opened linuxcnc via terminal, no difference. Axis thinks it is a ngc file and errors on the first <
03:19 PM gregcnc_: I'd put off an order to mcmaster for months to get the right fasteners, then end up with a bunch that i have noidea what they were for
03:20 PM gregcnc_: I had low profile m5's on my last order, can't figure out why
03:20 PM fragalot: jensor: I meant "python <yourscript>" to run the python script
03:20 PM fragalot: (asssuming that that's what you want to do)
03:20 PM jensor: ok
03:21 PM miss0r: fragalot: the er11 collect https://imgur.com/a/ZMcb5
03:21 PM miss0r: It took me 1,5 hours to make :]
03:21 PM miss0r: Still looks better than the cinesium version I found yesterday
03:21 PM fragalot: :D
03:23 PM gregcnc_: miss0r are there bearings in the nylon part? I see bearings further up.
03:23 PM miss0r: The two small grooves in the end of the shank, are for retaining two o-rings. They make a watertight seal, they forward the rotating force & they are electrical insulators, all in a small neat package :)
03:23 PM miss0r: gregcnc_: Yeah, two bearings in there
03:23 PM miss0r: The nylon is there for electrical insulation
03:23 PM gregcnc_: ok i get it
03:24 PM jensor: Entered: python <face.py> and get bash: syntax error near unexpected token `newline'
03:24 PM fragalot: jensor: remove the < >
03:24 PM jensor: ok
03:24 PM miss0r: WHO THE HELL RUNS OUT OF CIGGERETS AT THIS HOUR?! brb
03:25 PM Crom: I'm getting low myself
03:25 PM Tom_shop: is there a way to turn off the little 'I" messages that appear on the right side of the axis screen??
03:26 PM jensor: python: can't open file 'face.py': [Errno 2] No such file or directory. Apparently it can't find it.
03:26 PM fragalot: jensor: are you in the correct directory in the terminal?
03:27 PM fragalot: "cd .." goes up a folder, and "cd foldername" goes into a folder
03:27 PM Crom: EFFENING GREAT! I can't even use my current atom MB's since I don't have eth0 working... damn realtek R8168B
03:27 PM fragalot: ls shows you the current files in that folder
03:28 PM jensor: This is where I am: jack@debian:~$
03:28 PM jensor: I'll try ls
03:28 PM Crom: wish Tuesday was here... I could put in my mini-box.com order and amazon order
03:29 PM gloops: now then Crom thats not the way!
03:29 PM jensor: which folder should I be in?
03:30 PM jensor: Do I have to go t the folder where the python file is?
03:31 PM fragalot: jensor: yes
03:32 PM jensor: ok
03:34 PM andypugh: Does anyone know what the bar that shows opened files / apps is called in Stretch? I have lost mine.
03:34 PM andypugh: So I have to move window around to see what is behind them. (currently LinuxCNC is hidden behinf Geany, for example)
03:34 PM Crom: ok new computers are going to be 16GB RAM 2TB drives, with compact flash reader (with SD adapter) m300-LCD cases Mitac PD14RI-D N3150 fanless MB, with PCIe wifi+bluetooth, mounted on VESA mount on the wall, with ASUS 21 touchscreen monitor, with Dell wireless KB and mouse
03:35 PM gloops: these machine contructions often start out as swift decisive attacks, only to bog down and descend into a long campaign of trench warfare
03:36 PM Crom: I've never had reason to use eth0 on the old machines, they were always wifi
03:36 PM Crom: Now I'm going with a Mesa 7i92M I need a working eth0
03:36 PM jensor: now i get: jack@debian:~/linuxcnc/configs/bridgeport/ngc_files/PY_files$ face.py bash: face.py: command not found
03:37 PM Crom: updatedb; locate face.py
03:37 PM gloops: the routine in my garage is all too familair, long spells of boredom followed by brief bursts of violence
03:38 PM miss0r: ahhh. Now I can act like a person again
03:38 PM pfred1: gloops what's to get excited bout?
03:38 PM jensor: I'm there in the directory where face.py is located
03:38 PM pcw_home: if ~/linuxcnc/configs/bridgeport/ngc_files/PY_files is not in you path you need to type ./face.py
03:39 PM Crom: gloops, yep... spend money, wait, stuff comes in, still wait for more money, spend money, wait for stuff, wait for money, wait for stuff, YAY enough stuff, BUILD,BUILD, troubleshoot, troubleshoot, troubleshoot, troubleshoot, troubleshoot, troubleshoot, troubleshoot, troubleshoot, troubleshoot, troubleshoot, troubleshoot, working!
03:39 PM pcw_home: your path
03:39 PM gloops: pfred1 the endless times you have to accept - this is not going to get finished, today, or this week and probably the next
03:39 PM pfred1: echo $PATH
03:39 PM gloops: can dull the spirit a tadge
03:40 PM miss0r: gloops: Whats the project in question?
03:40 PM jensor: Now get: permission denied
03:40 PM pfred1: gloops I'm usually pretty patient
03:40 PM gloops: thats it Crom, exactly
03:40 PM pfred1: chmod +x face.py
03:41 PM gloops: miss0r im only talking about my piffling router, Crom is working on other things
03:41 PM andypugh: (chmod +x sets the eXecutable flag for a file)
03:41 PM Crom: I'm working on CNC'ing 2 mills, my 44991 X2, and a friends RF-31 33686
03:42 PM jensor: now get: ./face.py: line 7: syntax error near unexpected token `newline' ./face.py: line 7: `<!DOCTYPE html>'
03:42 PM pfred1: Crom doing ball screws on the Rong Fu?
03:42 PM miss0r: I sometimes have so many projects at hand down here, I just end up talking in here & browsing youtube because I simply can't seem to pick myself up and just get going!
03:42 PM Crom: pfred1: down the road a bit
03:42 PM pfred1: jensor you're probably using the wrong version of python
03:43 PM Crom: or we're going to get an X4 or a RF-45
03:43 PM pfred1: Crom I got so much backlash on my benchtop Chinese mill I donno
03:44 PM pfred1: jensor just have a look at the file and see if it says what version to use in the comments on the top
03:44 PM pfred1: jensor less face.py will suffice
03:45 PM Crom: probably rig a belville washer and a nut as a anti-backlash on the 33686
03:46 PM Crom: I also have belville washers coming for power drawbar
03:46 PM pfred1: plus with what I do with my mill I pretty much have to do all of that manually anyways
03:47 PM jensor: <link crossorigin="anonymous" href="https://assets-cdn.github.com/assets/frameworks-f27d807afb610bf126cbfb9ce429438a328e012239e5a77fc8152b794553dfc0.css" media="all" rel="stylesheet" />
03:47 PM jensor: no comments at top of file
03:48 PM pfred1: jensor yeah commenting code is always a nice touch
03:48 PM pfred1: don't always happen thuogh
03:49 PM pfred1: something like to make this work do this this and this
03:49 PM pfred1: an error like you got usually means wrong python version but not always
03:50 PM jensor: Instructions say: [FILTER] PROGRAM_EXTENSION = .py Python Script py = python If you don't have a [FILTER] section just add it Now use File Open in AXIS to open face.py and after you generate the G-Code select Write to AXIS and Quit.
03:51 PM pfred1: how Debian sets python up is kind of a hot mess too
03:55 PM gloops: im going to have to devise an anti backlash nut, ive got 3 nuts at hand, not really thought about it much yet
03:55 PM pfred1: my homemade HDPE lead nuts are anti-backlash
03:55 PM jensor: At this point I'll write my own gcode for facing.
03:55 PM gloops: 3 nuts might cause a bit of drag though
03:56 PM pfred1: getting the undersize just right is a bit of a trick though
03:57 PM pfred1: I made my own tap out of some spae lead screw but it was too tight so I peened some of the teeth http://i.imgur.com/qNzAo9S.jpg
03:57 PM fragalot: jensor: "python face.py"
03:58 PM pfred1: it is quite an art
03:58 PM fragalot: jensor: you're in the right folder now, but you still need to make python execute the file, face.py by itself is just a text file so it can't be a command. :)
03:58 PM pfred1: wholly fook!
03:58 PM gloops: excellent effort pfred1
03:59 PM pfred1: man don't do a locate face.py on this system
03:59 PM pfred1: locate face.py | wc -l = 137
04:01 PM pfred1: I could swear I have that script someplace though
04:02 PM pfred1: ah ha! locate face.py | grep "/face.py" /home/pfred1/bin/face.py
04:02 PM pfred1: right where I thought it'd be now that I'm thnking about it
04:03 PM pfred1: locate digs up all kinds of junk like test_interface.py tiledsurface.pyc etc.
04:04 PM jensor: Get: No such file or directory
04:04 PM pfred1: jensor it pops right up here
04:05 PM pfred1: Facing G-Code Generator Version 1.4.0
04:05 PM pfred1: scripts pheer my Linux-Fu
04:06 PM jensor: The file I down loaded claiming to be a pyton file came down with no extension. I changed its name from face to face.py
04:06 PM pfred1: I think I got mine out of my LinuxCNC install?
04:07 PM pfred1: I can't honestly remember now
04:07 PM pfred1: I do remember what I did with it thuogh
04:08 PM pfred1: I faced off this block of plastic to route PCBs on http://i.imgur.com/EdzcO2m.jpg
04:09 PM jensor: ilike your setup
04:09 PM pfred1: thanks that's my old Z axis
04:09 PM jensor: What cutter do you use for that?
04:10 PM pfred1: a 20 degree carbide cone
04:10 PM jensor: ok
04:10 PM pfred1: they're kind of tricky depth has to be spot on
04:10 PM pfred1: or ths cut gets wider or narrower
04:11 PM pfred1: I'm on the fence with isolation routing as a whole
04:11 PM pfred1: I mean it is convenient but I don't know if i like the big copper pours
04:12 PM jensor: Copper pours?
04:12 PM pfred1: I am thinking about trying some kind of resist and etching
04:12 PM pfred1: that's what i call big spots of copper on a board
04:12 PM pfred1: some call them ground planes but they're not connected to ground on my boards
04:13 PM pfred1: so it is more like just excess copper
04:13 PM jensor: I've done some pc board work like in your photo, I know what you mean excess copper.
04:14 PM jensor: All mine is done on my bridgeport.
04:14 PM pfred1: yeah if I'm not careful I can end up soldering the stuff
04:14 PM gloops: these should be doable on 3 axis, losing the undercuts wouldnt make a big difference https://i.pinimg.com/564x/14/6c/19/146c193cba9500b800b4c5ca23dfd0d8.jpg
04:14 PM Deejay: gn8
04:14 PM pfred1: that's pretty freaky gloops
04:14 PM gloops: would sell like hot cakes i reckon
04:15 PM pfred1: gloops think you can make one of these? http://i.imgur.com/c8su8ND.jpg
04:15 PM gloops: stuff like that anyway
04:16 PM pfred1: I think a pack of wild Indonesian kids carved that
04:16 PM miss0r: yay. I ground the inside taper of the ER11 collect. Now I can hardly get a measurement with a 0.001mm dial. I think it is good to go :]
04:16 PM jensor: pfred, thanks for your comments, I have to go now.
04:16 PM gloops: easy with a set of these pfred1 http://cdn.hartvilletool.com/images/uploads/5171_6836_popup.jpg
04:16 PM pfred1: can probably buy it for a coule cartons of cigarettes too
04:17 PM gloops: yeah and those kids probably used a fragment of kitchen knife bound into a bit of bamboo
04:17 PM pfred1: gloops they probably carve with spoons they sharpen on rocks
04:18 PM * gloops nods
04:18 PM pfred1: guy was asking $1,700 for it so I figured taking a picture was cheaper
04:18 PM gloops: was it wood though, or resin?
04:19 PM pfred1: wood
04:19 PM pfred1: it was the real deal
04:19 PM gloops: well its better than stealing cars for them anyway
04:19 PM miss0r: i need to get into wood carving lol
04:20 PM miss0r: that or car theft
04:20 PM pfred1: I've done a bit of carving it is kind of boring
04:20 PM pfred1: monotonous
04:20 PM miss0r: hehe. I was planning to have a cnc do the work for me
04:20 PM miss0r: then add a human touch in the end and call it hand made
04:20 PM pfred1: jolly good
04:20 PM pfred1: I have met the second ranked bird carver
04:21 PM gloops: wood carving is ok if you have time, who has the time these days
04:21 PM pfred1: he kept going on and on about how the firt ranked guy wa so much better than he was
04:21 PM pfred1: but he looked pretty good to me
04:22 PM pfred1: he was using a Foredom flex shaft tool
04:22 PM gloops: some use a knife, some chisels, personally id call knife work 'whittling'
04:23 PM gloops: a lot is done with power tools now
04:23 PM pfred1: here's the last thing I carved http://i.imgur.com/Yqsap43.jpg
04:23 PM pfred1: I didn'r have quite the right handle I wanted in my collection
04:24 PM pfred1: yeah I basically whittled that
04:24 PM gloops: pretty good pfred1, you cleft the wood yourself
04:25 PM pfred1: you mean split it? I did that on a band saw
04:25 PM gloops: oh i see, -2 points then
04:25 PM pfred1: just a branch I pulled out of my woods
04:25 PM pfred1: I think it's maple?
04:26 PM gloops: couldnt say
04:26 PM pfred1: the bark looks like maple to me
04:26 PM gloops: what is the object anyway?
04:27 PM pfred1: it is a hammer handle
04:27 PM gloops: well, you want ash for tool handles, split not sawn
04:28 PM pfred1: hickory is good too
04:28 PM pfred1: I htink all the ash is dead now?
04:29 PM gloops: hickory is common yes, i dont think its as good as ash, ive cracked loads of hickory sledge hammer shafts - my own ash shafts are stronger
04:29 PM gloops: the ash is still ok in england, ash dieback is here now though
04:30 PM gloops: i think some oredict we could lose 96% of ash trees
04:30 PM pfred1: yeah we got wiped out by beetles here
04:33 PM gloops: sure that wasnt elm?
04:33 PM pfred1: they might have went too?
04:33 PM pfred1: times are tough for trees
04:34 PM gloops: dutch elm disease, elm virtually non existent here now, although never was native
04:35 PM pfred1: birch is just about gone too
04:36 PM JT-Shop: the next county has the emerald ash boring beetle things
04:36 PM gloops: we still have birch, many consider it a weed
04:36 PM pfred1: indians considered it canoes
04:36 PM gloops: its the first tree to grow on wild ground, soon gets ousted by bigger trees
04:38 PM pfred1: JT-Shop there goes the neighborhood
04:38 PM JT-Shop: yup
04:39 PM pfred1: I have tens of thousands of pole pines
04:39 PM JT-Shop: anyone want a rooster... I'll email it to you
04:39 PM pfred1: dang stuff ain't evne good as fire wood
04:39 PM pfred1: you'd literally be better off rulling up newspaper and burning it
04:39 PM JT-Shop: man I've been burning a crap load of wood
04:39 PM gloops: i think a beech tree is the biggest living organism ever, somewhere, canada i think there is an entire forest that is all technically one beech tree - all the roots are connected underground, weighs millions of tonnes
04:40 PM JT-Shop: chickens are going to bed
04:40 PM pfred1: Canada got some trees
04:42 PM pfred1: I was up in northern Maine and I felt like an ant running around in the grass
04:42 PM pfred1: so many trees
04:43 PM gloops: the indians were hunter gatherers didnt cut the trees down
04:43 PM gloops: in europe they were all cleared off
04:43 PM pfred1: yeah they just burned them
04:43 PM pfred1: Indians were pyromaniacs
04:44 PM pfred1: there's more acres of woodland in the US today than the day the Pilgrims landed
04:44 PM gloops: why did they burn them?
04:44 PM pfred1: to clear underbrush
04:44 PM pfred1: made it easier to walk
04:45 PM pfred1: plus it stopped huge forest firres from breaking out
04:45 PM pfred1: also they were probably fire bugs with nothing better to do
04:45 PM gloops: yes see, they knew
04:46 PM pfred1: stupid White man don't understand the land though
04:46 PM pfred1: we put fires out
04:46 PM gloops: i remember one of the old farmers here when i was a kid, used to 'fire' all the hedgerows in the fields, burn out all the dead grass and rubbish in them
04:47 PM pfred1: we enacted a no burn policy in the 30s and it has turned into a disaster
04:47 PM gloops: i think he too was mainly a firebug though
04:47 PM pfred1: that's why we have these huge wild fires today
04:47 PM pfred1: no burn you're just stacking up fuel
04:48 PM gloops: lot to be said for the old ways, its all been forgotten now we think we know everything
04:49 PM pfred1: well the other problem is there's more people today to get caught up in any disaster
04:50 PM gloops: only parks will survive the population explosion
04:50 PM pfred1: I always found it odd that they rate tornadoes on how much damage they do to human buildings
04:56 PM gloops: well, bedtime here
05:29 PM phipli: almost done...

06:32 PM phipli: yes. Good
06:40 PM Crom: uplooading new vid with touch screen
06:41 PM Crom: 28% done, it's gonna take awhile
07:02 PM thochguertel_ is now known as thochguertel
09:45 PM Crom: gh 69% 31% to go still.. yeah 2hr's right...
10:39 PM roycroft: oh brother
10:39 PM roycroft: not that bot
10:45 PM Crom: https://www.youtube.com/watch?v=jXJ7vr8AJ5Y FINALLY nice 2 hours only took 5 hours
10:58 PM jesseg: I think it's the USS Contraption
10:59 PM Crom: My 3040?
10:59 PM jesseg: I think so :D
11:00 PM Crom: indeed. It's my back porch. All the saw dust is mainly from the house mate using the router, belt sander, or compound mitre saw
11:01 PM jesseg: I was referring to your CNC milling machine :D
11:01 PM jesseg: it's quite a contraption, I like it!
11:01 PM Crom: I need to move all the NON CNC crap to a new space
11:03 PM Crom: I'm loving GMOCCAPY and the touch screen
11:07 PM Crom: Like my minimill stand? it's the old A/C unit
11:13 PM `Wolf: what were you saying about the t nuts in the vid?
11:15 PM `Wolf: oh wait, yours has a different table then one I have on my x2
11:16 PM Crom: The harbor freight website says the 44991 takes 1/2" Tnuts -- it doesn't it takes 7/16" Tnuts
11:16 PM Crom: it's a tiny table
11:16 PM `Wolf: the table I have uses metric, same slots as the x1 micro mill
11:16 PM `Wolf: I ended up ordered 100 t-nuts from aliexpress
11:17 PM `Wolf: m6 thread
11:17 PM Crom: My rotary table uses M6 Tnuts, I had to take 0.022" off the bottom of them
11:18 PM Crom: I need to order some 1/16" 3" long parallels
11:21 PM XXCoder: Crom: 2 hours took 5 hours? ;)
11:22 PM XXCoder: also "harbour freight $4.99" what tiem is 5 bucks? autocraptions isnt clear
11:25 PM Crom: XXCoder: youtube app on my phone said. "Oh it'll take 2 hours to upload"
11:26 PM Crom: $4.19 for a Break out board on ebay
11:29 PM XXCoder: ahh ok :)
11:29 PM XXCoder: so making a cnc mill eh
11:36 PM Tom_L: i am yes :)
11:36 PM XXCoder: oh you too eh
11:37 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Y_Motormount2.jpg
11:37 PM Tom_L: took a chance and welded that in permanent
11:37 PM Tom_L: alignment is spot on
11:37 PM XXCoder: what was permently welded in?
11:37 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Y_Motormount1.jpg
11:38 PM XXCoder: oh that looked bolted on
11:40 PM Tom_L: https://www.youtube.com/watch?v=QCva7pnMtEQ
11:40 PM Tom_L: alignment test
11:42 PM Tom_L: i made a hard coupler to align them then i'll replace it with a regular one
11:42 PM Connor: I like Oldham couplers..
11:43 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Couplers.jpg
11:43 PM Tom_L: i'm gonna use the red one
11:43 PM Connor: Is that plastic or ruber?
11:43 PM Tom_L: i'm not sure
11:43 PM Tom_L: it's a little pliable
11:44 PM Connor: If rubber, can introduce backlash..
11:44 PM XXCoder: theres polastic/rubber hyrids
11:44 PM Tom_L: but i think it's plastic
11:44 PM Tom_L: it's pretty tight
11:44 PM `Wolf: oldham are great
11:44 PM Connor: Oldham's I use have a disk than can act as a 'fuse' which I like.
11:45 PM Connor: I won't use those helix style couplers ever again.
11:45 PM Tom_L: why?
11:45 PM `Wolf: https://i.imgur.com/JAQu2yN.png?1
11:45 PM Tom_L: one stall will kill em?
11:45 PM Connor: He ones from China.. Have broken on me too many times.. The develop stress fractures..
11:46 PM `Wolf: the oldham are tight as a solid connection, no backlash
11:46 PM injoi: hi there!
11:47 PM Connor: and they can tolerate miss-alignment if the shafts are parallel. But not necessarily centered with each other..
11:48 PM Connor: https://d2t1xqejof9utc.cloudfront.net/screenshots/pics/96de616b64bec5d992b129bf4195bd5a/large.gif
11:49 PM injoi: I have a quick question...
11:49 PM injoi: are there any long term problems running a Y-axis with linear rails/guide with a single motor?
11:50 PM Tom_L: why would there be?
11:50 PM injoi: im building a pnp machine and I want to only have 1 motor without coupling the two sides
11:50 PM Tom_L: is it a gantry?
11:50 PM injoi: yea
11:50 PM Tom_L: getting them aligned might present a problem
11:50 PM injoi: there is a bar between the two sides of the Y axis
11:50 PM Tom_L: you know lcnc 2.8 handles gantry setups better
11:51 PM Connor: With a PNP shouldn't be a issue if the moved from the middle...
11:51 PM injoi: i am planning on moving the gantry from one side
11:51 PM Connor: If your driving a single side, you'll need to couple them together..
11:52 PM injoi: https://hackaday.io/project/9319-diy-pick-and-place
11:52 PM injoi: thats what i thought however this guy was saying that linear rails can be driven without coupling....
11:52 PM Connor: I wouldn't
11:53 PM Connor: and you need to make sure your coupling bar is large enough that it won't "wind up" under tension..
11:54 PM injoi: yea...thats what i would assume
11:54 PM injoi: but then why did that guy from hackaday think that rails dont need coupling?
11:54 PM Tom_L: what about tubing?
11:54 PM Tom_L: would that be stiff enough?
11:55 PM `Wolf: because most poster on hackaday don’t know anything about engineering
11:55 PM Connor: injoi: No idea. Maybe because there isn't any load on the machine like on a CNC...
11:55 PM Crom: When I build my 5'x5' My Y rails are going to be 7' long so I can run one motor, and X is going to be 9' so I can do a A off the side of the table
11:55 PM `Wolf: https://i.imgur.com/NxyunPr.jpg driving both sides of something that has no side loading is easy
11:55 PM injoi: well i would couple the sides with an 80/20 bar so no doubt it be stiff
11:57 PM injoi: 'Wolf: yea im doing to drive both sides...i just wanted to see if there was some secret that the hackaday guy knew i didn't
11:58 PM Crom: but I think driving both sides would be better to be able to cut steel
11:59 PM `Wolf: anything with a gantry is best if driven from both sides IMO
11:59 PM injoi: agreed
