02:10 AM Deejay: moin
02:58 AM BitEvil is now known as SpeedEvil
04:51 AM jthornton: morning
04:51 AM XXCoder: hey jthornton funny thing happened today
04:51 AM XXCoder: we had a party at work
04:51 AM XXCoder: guess what I won lol
04:52 AM jthornton: a radio?
04:52 AM XXCoder: good try lol. expensive headphones
04:52 AM XXCoder: other guy wanted it so i exchanged it for echo dot
04:52 AM jthornton: even better
04:52 AM jthornton: what's an echo dot?
04:53 AM XXCoder: useless
04:53 AM XXCoder: its alexia device by amazon, you can ask it stuff and it can also do some IoT stuff
05:00 AM jthornton: winter solstice today
05:00 AM XXCoder: yeah
05:00 AM XXCoder: the longest darkest night
05:00 AM XXCoder: ironic that its quite bright here
05:00 AM XXCoder: tomorrow is brightest full moon
05:01 AM XXCoder: so today its quite bright moon, and finally clear night since weeks of dark and rain
05:01 AM XXCoder: will be brief. rest of week is all cloud and rain
05:08 AM Tom_L: morning
05:09 AM XXCoder: hy tom
05:14 AM jthornton: morning
05:15 AM Tom_L: 30F Hi 53
05:15 AM XXCoder: anyway while echo dot is useless might try to make gramphone for it once i get 3d printer
05:15 AM XXCoder: because why not
05:15 AM Tom_L: announced a big boost in hiring here yesterday
05:15 AM Tom_L: spirit
05:16 AM XXCoder: nice
05:16 AM XXCoder: sounds like biz is booming there
05:16 AM Tom_L: http://www.kake.com/story/39679083/training-and-hiring-workers-following-spirits-jobs-announcement
05:17 AM Tom_L: yeah they hired around 1k a while back now somewhere around 1.4k
05:17 AM XXCoder: nice
05:18 AM Tom_L: i was kinda concerned when boeing pulled out but it's just opened the door for more vendors
05:18 AM Tom_L: now they do boeing and airbus and more
05:18 AM Tom_L: airbus and dassault both built offices here
05:19 AM Tom_L: i think the airbus one is mostly for engineers
05:26 AM XXCoder: nice'
06:33 AM jthornton: I need to write a chicken database I think...
06:37 AM XXCoder: yeah? data getting too long without database?
06:41 AM jthornton: yea spreadsheet is getting big lol
06:41 AM jthornton: I keep all kinds of data on weather, eggs, light
11:18 AM gregcnc: SmarterEveryDay How to measure 1/1,000,000" https://youtu.be/T-xMCFOwllE
11:18 AM fragalot: 'sup
11:24 AM gregcnc: I sent my son to school with a fist full of these for his classmates. http://www.dieselrc.com/x/temp/img_20181221.jpg
11:27 AM gloops: breaking news - gatwick suspends main runway again
11:27 AM gloops: drone is back
11:27 AM fragalot: the "drone"
11:27 AM fragalot: gregcnc: but will they fit a 1960's piece of lego?
11:27 AM gloops: a drone
11:28 AM gregcnc: who has 1960's lego? these kids aren't 55 years old
11:28 AM gloops: those could be used as a dangerous projectile gregcnc
11:29 AM fragalot: gregcnc: trick question. the modern ones are the /EXACT/ same size.
11:29 AM gregcnc: isn't the modern minifig 70's era?
11:30 AM fragalot: probably, but the heads fit on the blocks too
11:30 AM gregcnc: yes
11:31 AM gregcnc: metal isn't ideal as it doesn't bend like the plastic
11:36 AM HighInBC: metal lego, just solder it
11:36 AM fragalot: friction weld it by frustration alone
11:37 AM gregcnc: aluminum on aluminum might be a permanent assembly
11:37 AM fragalot: or stainless on stainless
11:37 AM gloops: springs
11:50 AM Rab: gregcnc, those are awesome! When I clicked the link I was afraid it'd be fidget spinners.
11:51 AM gregcnc: my kids has a whole list of parts he wants me to make
11:53 AM gregcnc: I was going to engrave the features deeper and fill them with paint, but ran out of time and it looked OK
11:54 AM gregcnc: they came off the lathe at 10 last night
11:54 AM renesis: looks neat like that
12:02 PM gregcnc: Anyone use 5C collect in production much? easiest way to seal the gaps to prevent chips getting behind?
12:03 PM fragalot: silicone?
12:03 PM renesis: playdoh
12:03 PM fragalot: sealed collets designed for the task?
12:03 PM renesis: actually i wonder if that stuff is abrasive when it dries
12:03 PM gregcnc: never seen sealed 5C
12:04 PM gregcnc: silicone or rubber cord I'm thinking
12:04 PM renesis: arent they made to clamp down to no-gap or close?
12:05 PM gregcnc: no, 1/16" gap or so
12:05 PM renesis: yeah rubber cord sounds good
01:56 PM CaptHindsight: sent a package to a "customer" in France 6 weeks ago...
01:56 PM CaptHindsight: it's on its way back from France now...
01:57 PM CaptHindsight: customer says "3 weeks ago they missed delivery" and then didn't mention anything about it till today
01:58 PM CaptHindsight: am I just lucky or are people really this dumb?
01:58 PM fragalot: I've had that happen
01:59 PM fragalot: because I have an old (no longer legal) mailbox built into my wall, which I closed off on the inside & sealed on the outside
01:59 PM fragalot: somehow they managed to shove the delivery notice in that thing...
01:59 PM CaptHindsight: hah
01:59 PM JT-Shop: at least your getting your product back... they kept mine and got their money back
01:59 PM fragalot: only found out about it because I saw something else sticking out of it several months latr
02:00 PM CaptHindsight: do you have another mailbox hidden from sight?
02:00 PM CaptHindsight: a true mailbox, not sealed
02:00 PM fragalot: if you can call 'right at the driveway where you walk past to get to the front door" hidden, yes
02:00 PM CaptHindsight: hidden in plain sight
02:00 PM fragalot: indeed
02:01 PM CaptHindsight: they said the local post office had no info of the parcel
02:02 PM CaptHindsight: then why wait 3 more weeks to ask us to trace
02:02 PM JT-Shop: well start with 24v and work your way up to 220v to keep them from touching the no longer in service box
02:02 PM fragalot: they may not have any info if it's handed over to a different company
02:02 PM fragalot: JT-Shop: hard to do on brick :P
02:02 PM CaptHindsight: happen to know what France does with USPS parcels?
02:03 PM JT-Shop: add two metal buttons with a sign "mail box is behind you"
02:03 PM fragalot: last time I got one (belgium) it went via the standard post
02:03 PM JT-Shop: and "touch to open"
02:03 PM fragalot: JT-Shop: :-)
02:03 PM fragalot: i've got a plasma ball or 2 lying around that I no longer need
02:03 PM CaptHindsight: i wasn't able to navigate https://www.laposte.fr/particulier
02:03 PM fragalot: because why use 240V when you could have 8kV
02:04 PM * JT-Shop decides to quit work at 2pm today... hmm 3 past 2
02:04 PM CaptHindsight: ever notice that nobody in France is ever in this channel
02:05 PM fragalot: ... would you want them to be?
02:05 PM fragalot: I mean.. they're french
02:05 PM fragalot: they'd riot
02:05 PM JT-Shop: one guy used to be here he translated the manual to french
02:05 PM CaptHindsight: this channel could use a good riot
02:05 PM JT-Shop: not seen him in a long time
02:06 PM CaptHindsight: I've never seen anyone from Asia in here either
02:06 PM fragalot: the great filter.
02:07 PM JT-Shop: wtf my 6006-2RS bearings won't be here till 12-31 and the rest that I don't need first will be here on the 27th
02:07 PM CaptHindsight: i know there are some users in Japan
02:07 PM CaptHindsight: the Chinese are too proud to use LCNC
02:07 PM JT-Shop: I've shipped to Korea but never Japan
02:07 PM JT-Shop: and Hong Kong once
02:08 PM CaptHindsight: $1 windows disk and a copy of Mach is common
02:08 PM rmu: http://elm-chan.org/
02:11 PM gregcnc: skyfirecnc is using linuxcnc
02:12 PM CaptHindsight: gregcnc: I noticed a local dealer for lathes made in the UK
02:13 PM gregcnc: there was something I was supposed to tell you...hmmmmm
02:13 PM CaptHindsight: https://www.wickman-group.com/wickman-products/
02:15 PM gregcnc: oh expensive stuff
02:16 PM CaptHindsight: never heard of them before
02:16 PM gregcnc: me too, but multi spindle is bound to be
02:17 PM CaptHindsight: https://www.wickman-group.com/our-machines/ or these
02:19 PM CaptHindsight: http://www.calcocutaways.com/ a business that specializes in making cutaways
02:19 PM gregcnc: manurhin i've heard of
02:20 PM gregcnc: oh I visited a guy locally with 4 edm in his basement
02:20 PM CaptHindsight: i figured that a manufacturer would just cut open one of their own rejects
02:21 PM Rab: CaptHindsight, neat
02:21 PM fragalot: CaptHindsight: good cutouts can take a lot of planning - the manufacturer may have better things to do with their time
02:21 PM gregcnc: strange i've never heard of them
02:22 PM CaptHindsight: i come across all sorts of businesses that don't advertise using Google maps
02:22 PM gregcnc: been wandering the industrial parks?
02:23 PM CaptHindsight: was the other day
02:23 PM gregcnc: these are all down the street
02:24 PM gregcnc: I saw chicago plastic moved into the old eisenmann warehouse
02:25 PM CaptHindsight: there is a t-slot extruder down the road
02:26 PM CaptHindsight: but you have to order from someone miles away
02:27 PM fragalot: isn't "miles away" like.. your closest neighbor in the US?
02:27 PM CaptHindsight: depends
02:28 PM CaptHindsight: what I find odd is people that want to live >1 hour out of a large city but 20ft from a cluster of homes in the middle of no where
02:29 PM CaptHindsight: 30 houses, steps apart but miles from anything else
02:29 PM gregcnc: pingree grove?
02:30 PM -!- #linuxcnc mode set to +v by ChanServ
02:32 PM CaptHindsight: https://www.frame-world.com/features/smooth.htm
02:32 PM gregcnc: yeah they turn up on 8020 searches
02:32 PM gloops: i dont like cities
02:33 PM ziper: looks expensive
02:34 PM CaptHindsight: pricing was around 8020's
02:34 PM CaptHindsight: you have to remember that they get you on the hardware, not the extrusions
02:38 PM Rab: Less good grammar!
02:39 PM CaptHindsight: we learned gooder English in school
02:40 PM gloops: oscar wilde said that england and america were 2 nations divided by 1 language
02:41 PM gregcnc: and an ocean?
02:41 PM gloops: luckily for you, yes
02:42 PM CaptHindsight: one theory from the outcome of the Revolutionary war was the poor use of English on this side
02:43 PM CaptHindsight: from/for
02:43 PM gregcnc: it's only getting worse over time
02:43 PM CaptHindsight: and that we kept their accent and they evolved
02:44 PM CaptHindsight: so a 250 year old Englishman would sound like a modern American (USA version)
02:44 PM methods_: crikey mate
02:44 PM methods_: say it isn't so
02:45 PM CaptHindsight: we have recordings that go back 100 years..
02:45 PM gloops: without the drawl
02:46 PM CaptHindsight: so it must have evolved rapidly from the late 1700's to the late 1800's
02:47 PM gloops: iwatched a video of some southern american bloke with a router, i did get the gist of what he was saying, but the drawl spoiled it
02:47 PM CaptHindsight: I'd blame it on the French but the Canadians don't sound like anyone from Virginia
02:49 PM CaptHindsight: gloops: watch a few of these and you'll be able to decipher it https://www.youtube.com/watch?v=a8sSAeey89s
02:50 PM gloops: yeah thats him
02:52 PM gloops: yorkshire dialect https://www.youtube.com/watch?v=ScELaXMCVis
02:55 PM gloops: im pondering a B axis, dont know if i have enough pins left on the BOB though

03:02 PM CaptHindsight: https://3dprint.com/232233/comparing-operational-characteristics-of-plastic-3d-printed-spur-gears/
03:02 PM CaptHindsight: PLA did better than ABS for the gears
03:02 PM fragalot: that's fairly impressive.. I wonder if they can control the warpage in any way
03:03 PM fragalot: PLA is harder than ABS, so that's not very surprising
03:03 PM fragalot: it's also fairly good at self lubricating
03:06 PM Rab: Does it perform better than mazak?
03:06 PM CaptHindsight: PLA vs Mazak, lets see
03:08 PM CaptHindsight: fragalot: looks like they just tightly control feedrate and current
03:08 PM CaptHindsight: not the smoothest parts
03:08 PM fragalot: CaptHindsight: it seems to do a fairly good job based on that singular video
03:09 PM CaptHindsight: the print rate is about SLS
03:09 PM CaptHindsight: res is lower though
03:10 PM Rab: Failure mode: gear train eaten by rats
03:11 PM fragalot: xD
03:11 PM fragalot: 'left out in the sun'
03:11 PM fragalot: or in a car
03:11 PM CaptHindsight: I usually hear about gears done with SLA vs FDM
03:11 PM CaptHindsight: faster print rate, better res
03:11 PM fragalot: higher density
03:11 PM CaptHindsight: material cost is higher
03:12 PM fragalot: sure, but the parts are typically stronger
03:23 PM CaptHindsight: which parts are stronger?
03:27 PM CaptHindsight: if you need 1-2 gears of that type a small CNC mill would be the way to go
03:28 PM fragalot: CaptHindsight: due to a better density, all identical parts made of identical materials are likely stronger in sls.
03:28 PM CaptHindsight: fragalot: what are you comparing to SLS?
03:28 PM fragalot: fdm
03:29 PM CaptHindsight: thanks
03:29 PM fragalot: (you were the one to bring that one up)
03:29 PM fragalot: :P
03:29 PM gloops: route 1 diy lathe https://www.ebay.co.uk/itm/Metal-Wood-Lathe/153306272110?
03:29 PM CaptHindsight: fragalot: I mentioned SLS and SLA so i wasn't sure of what you were comparing
03:30 PM fragalot: 22:09 < CaptHindsight> I usually hear about gears done with SLA vs
03:30 PM fragalot: FDM
03:30 PM fragalot: wait
03:30 PM CaptHindsight: never mind
03:30 PM fragalot: ._. I realize where i went wrong
03:30 PM fragalot: lol
03:30 PM CaptHindsight: why i asked
03:34 PM fragalot: I'm off, cya
03:43 PM CaptHindsight: https://www.youtube.com/watch?v=blaZ5tz0_6E cutting helical gears with some fancy indexing jigathing

04:06 PM gloops: The UK's ranking in @Forbes' 'Best Countries for Business' in the world: 2018: 1st 🇬🇧 2019: 1st 🇬🇧
04:08 PM Deejay: gn8
04:20 PM treats: I have a noob question that I think is a result of limited vocabulary. It is also maybe Fusion 360 specific. I'm trying to 'explode' multiple bodies to minimize waste during the CAM phase of my project. Specifically 2D Contour with an 1/8 straight cut.
04:24 PM gloops: nesting?
04:26 PM treats: Not sure... I'll look into that. Basically my design comes to tight points and I'm forced to use CAD to compensate for my CAM
04:27 PM gloops: nesting is where you arrange 2d parts on the material to get the maximum parts and least waste
04:28 PM gloops: i.e efficiently
05:04 PM ziper: I didn't think i'd have this much trouble following a template in wood
05:04 PM ziper: trying to attach the linear rail car to the gantry
05:11 PM jthornton: yea winter solstice for folks north of the equator
05:12 PM jthornton: spring is coming and the days are getting longer by seconds every day
05:22 PM CaptHindsight: when the great winter yak loads up the trailer full of toys to be delivered to all the good girls and boys
06:09 PM Tom_L: judging from traffic, there aren't many of those
06:12 PM Tom_L: CaptHindsight what resin would they use on carbon fiber to allow you to heat mold it at a relatively low temp?
06:12 PM Tom_L: ie 210F
06:13 PM CaptHindsight: interesting
06:13 PM Tom_L: veru
06:13 PM Tom_L: y
06:13 PM CaptHindsight: they usually use thermosets, they don't really soften much when heated
06:14 PM CaptHindsight: they might flex a little then as you heat them more just burn
06:14 PM Tom_L: put it in a watertight bag and stick it in some boiling water for 15 min
06:14 PM CaptHindsight: if they use a themoplastic then you could heat it to flex it
06:15 PM jdh: I have some heat moldable carbon sole bike shoes
06:15 PM Tom_L: similar thing here
06:15 PM jdh: 160f for them
06:16 PM CaptHindsight: yeah skates are also similar
06:16 PM CaptHindsight: heat to sort of mold
06:16 PM Tom_L: CaptHindsight, that's what got me wondering
06:16 PM CaptHindsight: you could make it
06:16 PM CaptHindsight: but ...
06:17 PM CaptHindsight: how well does it hold up at working temp?
06:17 PM CaptHindsight: working temp say 30C
06:17 PM Tom_L: good
06:18 PM Tom_L: they tell you to re'do it every few months
06:18 PM CaptHindsight: and then flexible at 70C
06:21 PM CaptHindsight: Polycaprolactone might be one
06:21 PM CaptHindsight: https://en.wikipedia.org/wiki/Polycaprolactone
06:27 PM CaptHindsight: looks like they blend it with PLA to raise it's melt temp
06:27 PM CaptHindsight: its/it's
06:30 PM CaptHindsight: Tom_L: how much CF is in yours?
06:31 PM CaptHindsight: also wondering if they have laminations throughout or just on the surfaces
06:48 PM treats: gloops, you were right, nesting is exactly what I'm looking to accomplish.
07:02 PM Tom_L: CaptHindsight i'm not sure
07:03 PM Tom_L: pretty sure it's laminated throughout
