03:35 AM selroc: hello
04:56 AM TekniQue_ is now known as TekniQue
05:57 AM jthornton: morning
05:58 AM XXCoder: yo
05:59 AM XXCoder: dang uge dead snake https://www.youtube.com/watch?v=IogEiKhEJFo
06:48 AM jthornton: it's raining and it's supposed to be clear today!@
11:21 AM gloops: no cnc in the production of the jeans youre wearing right? https://www.facebook.com/1168411098/posts/10212179696985486/
12:33 PM fragalot: hi
12:49 PM gloops: interesting random factoid on ITV news tonight - the average Venezualan lost 22kg in weight during the last year (thats 48 lbs or three and a half stones)
12:50 PM MarcelineVQ: So that's the secret to weight loss
12:50 PM gloops: yep, no matter how much oil youve got, there are still ways to get thin
12:50 PM MarcelineVQ: Are they measuring people, guessing, or just taking the weight off as an average by subtracting dead people?
12:51 PM Tom_L: you must log in to view...
12:51 PM gloops: im not sure what method they used but the people in the clip didnt look overfed
12:51 PM MarcelineVQ: Who's doing this measuring, in any case.
12:52 PM gloops: no idea
12:52 PM fragalot: ITV news editors
12:52 PM gloops: it was just 'news' on TV
12:52 PM fragalot: "we need a story"
12:53 PM MarcelineVQ: It's not news if you don't know where it comes from gloops. Though it is at least believable.
12:53 PM fragalot: MarcelineVQ: he does know where it comes from
12:53 PM fragalot: it was on ITV.
12:53 PM fragalot: therefore it MUST be true
12:53 PM gloops: ahh, i never said it was true did i
12:53 PM MarcelineVQ: I give gloops more faith than that fragalot
12:53 PM MarcelineVQ: Just curious about what's behind it
12:54 PM MarcelineVQ: it being the story
12:55 PM gloops: it began by saying prices had doubled in the last couple of days, then it said water was becoming a real problem etc
12:55 PM Tom_L: hah that ebay discount finally got here
12:56 PM CaptHindsight: pretty sure eating less and more activity is a proven method to lose weight
12:57 PM FinboySlick: CaptHindsight: That and a centrally-planned economy, apparently.
12:58 PM gloops: yes, putting prices up by 10000% while reducing income has also been knownn to work
12:58 PM CaptHindsight: FinboySlick: sure, this way the majority of the nation loses weight
12:58 PM gloops: its like that old inuit said - you cant eat oil
12:58 PM CaptHindsight: the Venezuelan Diet
12:58 PM FinboySlick: When they socialized Ukrainian farmers, the state printed posters reminding people that it is wrong to eat your own children.
01:00 PM CaptHindsight: so extreme socialism is bad?
01:00 PM CaptHindsight: or what's the other word for extreme in this case
01:01 PM gloops: not for socialists no
01:01 PM gloops: only the people who voted for them
01:01 PM MarcelineVQ: That inuit line is so confusing hehe
01:01 PM CaptHindsight: crony, faux, corrupted like "capitalism" of today
01:02 PM CaptHindsight: Ukrainians are fun loving people
01:02 PM CaptHindsight: unlike the current Russian leaders
01:03 PM MarcelineVQ: By which I mean I don't get the joke :>
01:03 PM CaptHindsight: Putin is like the crabby person at the party that doesn't like jokes
01:04 PM CaptHindsight: why I'm firmly against cats having any control over self driving cars
01:05 PM gloops: When the Last Tree Is Cut Down, the Last Fish Eaten, and the Last Stream Poisoned, You Will Realize That You Cannot Eat Money
01:05 PM MarcelineVQ: Well sure, cats are sociopaths.
01:05 PM gloops: it was actually a cree indian MarcelineVQ - i just threw in the inuit for a laugh
01:05 PM MarcelineVQ: Oh okay ehe, that's why it didn't work
01:05 PM Tom_L: standard shipping 3.95: delivery Tues, expedited shipping 6.95: delivery Tues.
01:05 PM MarcelineVQ: See traditionally inuit routinely ate oil, it's a great source of energy and extra weight, it came from animal fat and powered their lamps too.
01:06 PM CaptHindsight: Tom_L: I've noticed similar
01:06 PM CaptHindsight: different price, same day arrival
01:06 PM gloops: are there any real eskimos left?
01:06 PM fragalot: I like the $100 EMS shipping from china
01:07 PM fragalot: vs the free shipping
01:07 PM CaptHindsight: oh I think he meant crude oil
01:07 PM fragalot: because the free typically comes faster with lower taxes
01:07 PM MarcelineVQ: That depends a lot on who's calling them real.
01:07 PM FinboySlick: gloops: Kinda.
01:07 PM MarcelineVQ: I'm sure there's guys up north who call themselves that, and that's up to them.
01:07 PM CaptHindsight: seal blubber doesn't contain any crude oil
01:07 PM gloops: theyve all got thermals and snowmobiles these days
01:07 PM CaptHindsight: well maybe just trace amount
01:08 PM MarcelineVQ: Just crude oil byproducts :>
01:08 PM gloops: and iphones
01:08 PM Tom_L: CaptHindsight, i chose the 6.95 cause i want it Tues
01:10 PM CaptHindsight: what I find annoying is chosing "regular shipping" listed as USPS that later ships as UPS so no Saturday delivery as expected
01:12 PM Tom_L: 15% off all ebay today only
01:12 PM CaptHindsight: Last Location: Bensenville, IL, United States, Thursday, 09/27/2018 (so ~30 miles away)
01:12 PM CaptHindsight: Estimated Delivery:
01:12 PM CaptHindsight: Monday, 10/01/2018
01:13 PM CaptHindsight: 4 more days
01:14 PM Tom_L: got a couple thread mills to play with
01:16 PM CaptHindsight: M2, 2.5,3 and 4 are my recent thread sizes
01:16 PM CaptHindsight: and of course all in aluminum
01:16 PM Tom_L: i was looking at them and it seems this one can do quite a few
01:17 PM Tom_L: #10 M5 M6 and probably more
01:17 PM Tom_L: the metric one had the same basic dimensions
01:19 PM Tom_L: i think they reach a point the thread depth is more than the point so you gotta bump up a size
01:20 PM CaptHindsight: Tom_L: did you find a new spindle?
01:20 PM CaptHindsight: for the mill
01:20 PM Tom_L: nope, still using the sherline
01:21 PM Tom_L: that's why i'm getting these. the motor is too weak to do rigid tapping
01:28 PM CaptHindsight: https://postimg.cc/gXpPdtPD another Automation technologies special to be reworked
01:29 PM CaptHindsight: came with some steppers without specs
01:29 PM FinboySlick: That's an interesting extrusion profile.
01:30 PM FinboySlick: Looks a bit more sturdy than the typical ones.
01:30 PM CaptHindsight: part number is on the motors but no match anywhere
01:30 PM CaptHindsight: FinboySlick: I'll have to compare
01:30 PM CaptHindsight: no nuts to adjust preload on the screws
01:31 PM CaptHindsight: red oxide coated nuts for spaces between the steppers and the mounts
01:31 PM CaptHindsight: spaces/spaers
01:31 PM CaptHindsight: spacers
01:33 PM Tom_L: for $60 i could get it a day sooner :)
01:34 PM CaptHindsight: https://postimg.cc/7bqwTvvy strain relief?
01:34 PM CaptHindsight: is that what the clamp is for?!
01:35 PM Tom_L: naw, the clamp is just to pinch the wires to cause a short
01:35 PM CaptHindsight: yeah, next day air has gotten pricey
01:35 PM Tom_L: they absolutely did the right thing there...
01:36 PM CaptHindsight: somebody sent me a return label for #6lbs to CA overnight and it was $160
01:36 PM CaptHindsight: FEDEX
01:49 PM gloops: are we making our own chinese steppers yet?
01:55 PM CaptHindsight: heh, Nema 17 stepper shares the threaded holes for mounting as well as body/coils, you tighten the mounting screws and the screws through the back popped out
03:06 PM Loetmichel: *gnhihi* just came back from meeting an old pal from kid days... we sat at the river outside in the beergarden... at 21:30 the friend started to complain about "its getting cold, lets pay and go home" $me "sure. But are you getting more sissy with age? You sit there in a fleece jacket and are freezing, i am sitting here in a tshirt and 3/4 long cargo pants and i am not cold..." His retort:
03:06 PM Loetmichel: "YOU have a thick thermal insulation layer under your skin, i dont!" $me: "touché" :-)
03:08 PM Loetmichel: ( and it wasnt really cold. Only 12°C when we left, according to the thermometer at the entrance of the beergarden )
03:12 PM Deejay: gn8

06:07 PM Tom_L: quiet evening
06:18 PM pcw_mesa: BANG BANG BANG CLATTER CLATTER
06:19 PM * JT-Shop just got back from a 550 mile road trip
06:20 PM Tom_L: 2 3 or 4 wheels?
06:20 PM JT-Shop: 4
06:21 PM JT-Shop: picked up a Jet 14/42 wood lathe
06:22 PM tiwake: jet seems like crap though
06:23 PM JT-Shop: it's an older jet so maybe better than using my neighbors shop smith
06:26 PM Tom_L: iirc my bud had a jet / bridgeport at the shop and it seemed ok
06:26 PM JT-Shop: it sure is a heavy beast
06:27 PM JT-Shop: time to tuck the hens in
06:30 PM Tom_L: calculating a thread, is there a direct relationship between the thread depth and it's pitch?
06:33 PM Tom_L: ahh... 'height' = .866 * pitch
06:33 PM Tom_L: on a V thread
06:34 PM Tom_L: at least that's a start point for the cad on a single point thread
06:36 PM skunkworks: https://www.youtube.com/watch?v=5Y7p6G8EJNQ
06:37 PM Tom_L: i found not much gets under mine
06:38 PM Tom_L: you gonna slice somebody's arm off if they're behind it :)
06:40 PM _unreal_: now I feel dumb. I spent a bunch of time setting up this board an RTC only to really look closer and discover its not an RTC..... rather its an inverted RTC... it tells elapsed time....
06:40 PM _unreal_: not time/date WTF....
06:40 PM _unreal_: I have some DS1302's somewhere but its been so long I dont remember where they are :(
06:40 PM _unreal_: trying to locate them sort of
06:41 PM _unreal_: just bumbed
06:41 PM skunkworks: Tom_L: hope not ;)
06:41 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/RTC3.jpg
06:42 PM Tom_L: 1302
06:42 PM Tom_L: skunkworks i'd just stretch some neoprene across it honestly
06:46 PM _unreal_: skunkworks, nice concept but that little channel will will faster then you can empty it doing a motion
06:46 PM Tom_L: i think that part is ok
06:47 PM Tom_L: but chips will stick to the brush
06:48 PM _unreal_: I would suggest trying to add a FOLD in the middle. maybe 2 folds origami if you will.
06:48 PM Tom_L: with coolant they'll stick to the back too
06:48 PM _unreal_: to defelect chips to the side
06:48 PM Tom_L: i just blow mine off when i'm done
06:48 PM _unreal_: OR use an active vacuum collection system
06:48 PM Tom_L: that gets messy
06:49 PM Tom_L: especially with coolant
06:49 PM _unreal_: depends on what your milling... anything requiring cooling/lubricant total agreement
06:51 PM _unreal_: OH WIERD I just got 3 comercials in a row on youtube
06:53 PM Tom_L: hmm these guys say .65 * Pitch
08:36 PM CaptHindsight: with $20 Chinese airbrush and old ink https://i.postimg.cc/YSstTQK9/LCNC-_AB_00.jpg
08:47 PM sync: not bad
08:47 PM pink_vampire: CaptHindsight: it is your cnc?
08:47 PM CaptHindsight: nothing tuned yet, just first pass or two, you can see the entire path
08:48 PM pink_vampire: is that a 3d printer frame?
08:48 PM pink_vampire: CaptHindsight: ^
08:49 PM ziper: https://www.youtube.com/watch?v=YmRrS_tlD5k
08:50 PM pink_vampire: ziper: just why?
08:50 PM ziper: pink_vampire, so that you dont lose your tools
08:51 PM CaptHindsight: how did you get a youtube from the 70's?
08:51 PM ziper: i am patient
08:52 PM CaptHindsight: I can airbrush my name in all my tools now
08:53 PM pink_vampire: CaptHindsight: you cab use bluing
08:53 PM pink_vampire: can*
08:58 PM CaptHindsight: pink_vampire: ballscrew router
08:58 PM CaptHindsight: the real ones use linear servos or belt drives
09:01 PM pink_vampire: CaptHindsight: what is the max speed you get?
09:02 PM pink_vampire: it is look very consistent line
09:03 PM CaptHindsight: https://imagebin.ca/v/4HCxDgSmsztG 5-axis all linear servo
09:03 PM CaptHindsight: pink_vampire: with linear servos I can get >1m/s
09:05 PM infornography: where do I get linear servos?
09:05 PM TurBoss: CaptHindsight: wow

09:06 PM CaptHindsight: https://www.aerotech.com/product-catalog/motors/linear-motor.aspx
09:07 PM pink_vampire: CaptHindsight: i'm a bit confused, so the lines you did, was on a ballscrew system or linear servos?
09:08 PM infornography: thanks
09:08 PM CaptHindsight: the pic is from a ballscrew router https://postlmg.cc/gXpPdtPD
09:09 PM CaptHindsight: after rework https://postimg.cc/56QYXjCR

09:13 PM CaptHindsight: 80N force, 2.5m?S
09:14 PM CaptHindsight: probably 1/7th the list price
09:14 PM pink_vampire: how much they cost?
09:15 PM CaptHindsight: ^^ that one has two stages
09:16 PM CaptHindsight: pink_vampire: >$5k and up new depending on size , power and speed, accuracy
09:17 PM pink_vampire: 5K each?
09:17 PM CaptHindsight: yes
09:18 PM pink_vampire: is that you "hobby" machine???
09:18 PM CaptHindsight: sometimes
09:18 PM CaptHindsight: https://www.parkermotion.com/products/Belt_Driven_Linear_Actuators__5485__30_32_80_567_29.html
09:19 PM CaptHindsight: belt driven positioners up to 5m/S but lower accuracy that linear servos
09:19 PM CaptHindsight: that/than
09:19 PM pink_vampire: just insane

09:31 PM pink_vampire: very cool idea!!!!!!!!
09:32 PM pink_vampire: I dont like way covers
09:32 PM skunkworks: it is sorta coppied from a matsuura
09:33 PM pink_vampire: I need something for my Z axis
09:34 PM pink_vampire: I love the M111
09:39 PM infornography: that video needs more views, very cool
09:44 PM CaptHindsight: skunkworks: did you make the way cover for the Z?
10:11 PM skunkworks: CaptHindsight: the bellows? no. came with it
10:17 PM skunkworks: pink_vampire: m111?
10:19 PM pink_vampire: skunkworks: M111 is my Done gcode that send command to my stacklight
11:15 PM pink_vampire: is the a way to get the direction of path?
