12:18 AM fragalot: hi
12:22 AM pink_vampire: hi
12:57 AM IchGucksLive: hi all from a sunny morning
12:59 AM IchGucksLive: im off 2 school
01:35 AM miss0r: goodmorning
01:37 AM Deejay: moin
01:52 AM MarcelineVQ: "<CaptHindsight> we came across a guy today on a trail that was attacked by a dog up the trail, he didn't want to report the attacker since he "didn't want to be a dick or nothin"" I get that point of view, since they'd probably destroy the dog, you're not allowed to destroy the owners it turns out
01:53 AM gloops: agree mainly
02:07 AM miss0r: I have to turn the OD of some small round aluminium covers. They are mushroom shaped ish... They are raw cast, hand finished. jeez, This is gonna be a mouthfull.. all 56 of them
02:08 AM MarcelineVQ: wee
02:09 AM miss0r: i was told by the costumer to reduce the OD by 1mm.. and I asked him 'where' ? :) Just take off 1mm!
02:09 AM miss0r: alright :D
02:09 AM pink_vampire: how much current 14 awg can take?
02:10 AM miss0r: pink_vampire: 15amps
02:10 AM miss0r: scratch that, 20 amps
02:12 AM pink_vampire: i will use 12,
02:12 AM pink_vampire: thanks!
02:15 AM gloops: we only get 13-15 amps on domestic supply
02:18 AM fragalot: Hi.
02:18 AM pink_vampire: hi
02:20 AM miss0r: hello
02:21 AM fragalot: miss0r: looks like it's the bottom Y casting of the mill that's off in both Z and X directions
02:22 AM fragalot: 0.01/30mm in X, and 0.02/10 in Z... got more measuring to do before I do anything though
02:22 AM fragalot: it also looks like they welded up about 4 or 5 large pores
02:23 AM miss0r: :o
02:23 AM miss0r: If need be, you can ship it here
02:24 AM miss0r: It wouldn't be hard to mill it back to squareness, then you can scrape the rest of it
02:24 AM miss0r: or go to a local shop and have it milled properly
02:25 AM fragalot: need to get/make me something to lift the head off of it
02:25 AM fragalot: when we put it in it took 3 people to lift it into place, and that was NOT a fun experience :)
02:25 AM miss0r: Indeed :]
02:26 AM miss0r: not to call you a wuss(yeah a little); back when I got my arboga u2508, I got that into my shop by myself.
02:27 AM fragalot: yours is a garage with a level entrance though isn't it?
02:27 AM fragalot: mine has a 300mm step
02:27 AM miss0r: That thing must weigh 300kg easy..
02:27 AM miss0r: well, I had to get this in through the door.. its a 100mm step, but not 300 ;D
02:27 AM fragalot: and an 80cm wide path to it
02:28 AM miss0r: I did use a handtruck, though ;D
02:28 AM fragalot: that said - how keen would you be to move that arboga back out & then in again? :P
02:28 AM fragalot: hehe
02:28 AM fragalot: that's fine once you get it on the ground
02:28 AM miss0r: Lucky for me I don't have to worry about that :D I sold it over two years ago, so it is gone ;)
02:29 AM miss0r: I had help when getting it out ;)
02:31 AM gloops: have you got a toolpost grinder for lathe fragalot https://www.youtube.com/watch?v=_p3NVvE2Zuc
02:32 AM fragalot: yes .
02:32 AM gloops: thats how to do it
02:32 AM fragalot: if it were bigger, sure
02:36 AM miss0r: :D
02:37 AM miss0r: fragalot: I have 56 small aluminum covers to reduce the OD by 1mm on.
02:37 AM miss0r: Did I mention they are raw cast, with handfinished & polished top? NOTHING on there are close to round
02:39 AM gloops: if in the lathe, grind radius cutters to suit?
02:39 AM fragalot: miss0r: lmao.
02:40 AM fragalot: miss0r: can you turn it between centers?
02:40 AM miss0r: fragalot: Theres a 6mm thread in one end and it is 20 degrees off from what is the closest to the centerline of the OD I need to reduce
02:40 AM miss0r: Nope. Nothing close enough to a centerline to use.
02:40 AM BitEvil is now known as SpeedEvil
02:44 AM miss0r: I'm milling a square mandrel, hoping that will help :D
02:44 AM miss0r: lemme take a picture of the part in question
02:44 AM miss0r: https://imgur.com/a/LDoP7Cq I need to reduce the OD that is pointing up on the middle one
02:45 AM gloops: not difficult miss0r, one cutter ground to that form, come in adjacent
02:45 AM miss0r: Alright... How do you propose I set this up in the lathe? :S
02:46 AM miss0r: I have 56 of these, I do NOT have the time to set them all up in a 4 jaw, and I cannot scratch the polished surface
02:47 AM gloops: if theres enough, grip the round, use a backing washer, if not make a tapped mount and hold that
02:47 AM gloops: you have to take 1mm off the mushroom head?
02:47 AM miss0r: no
02:47 AM gloops: oh
02:48 AM miss0r: The thinner 'shaft' on the backside
02:48 AM gloops: yeah make a square mount, tap it, hold them like that
02:49 AM miss0r: what I am working on ;)
02:50 AM gloops: could maybe make a washer to cover the shroom while turning, you wont catch that anyway
02:50 AM SpeedEvil: miss0r: take some tube of the appropriate diameter, with a transition of 1mm over the length of the pipe, run a boring bar with an appropriate thingy on the end to make a sawtooth, lube and press through on the end of a squared off bar.
02:52 AM SpeedEvil: Inverse broach sort of
02:52 AM SpeedEvil: Oh - nvm
02:52 AM SpeedEvil: Sorry
02:53 AM miss0r: :D
03:00 AM fragalot: miss0r: does the OD have to spin true to anything in particular?
03:02 AM miss0r: there is nothing to spin true to :D
03:03 AM miss0r: So, i'm just turning it 'true' to the internal square
03:03 AM miss0r: ... "square"
03:10 AM miss0r: well, my current setup is repeateable within 0.05mm which is PLENTY good for this s***
03:10 AM miss0r: ;)
03:17 AM miss0r: Sadly, i'm not getting a very good surface finish with this setup...
03:19 AM fragalot: try a shearing tool
03:21 AM gloops: cast ally ive turned doesnt finish with tool, file/emery cloth, its almost smearing it smooth
03:21 AM MarcelineVQ: smearing metal is called burnishing I think :>
03:23 AM gloops: well not quite burnishing, if the word 'burnished' is in the bill its an extra 25%
03:23 AM miss0r: :D
03:24 AM miss0r: anyway, the surface finish is plenty good. This 'plug' needs to be glued into a hole, so I can just call it a feature, that the surface has some roughness for the glue to catch on to
03:24 AM MarcelineVQ: you will go far my son
03:26 AM miss0r: ;)
03:27 AM gloops: im going far right now, where i should have gone an hour ago
03:28 AM MarcelineVQ: adding to the alu woes of the day I've got a hex broaching I'm doing to a pulley and it keeps loading up the file hehe
03:29 AM miss0r: hehe
03:29 AM MarcelineVQ: at least now I know that if I see a coarse square file at a yard sale sometimes I'm going to want it
03:29 AM MarcelineVQ: *sometime
03:30 AM MarcelineVQ: So that I can load up two instead of just one, if nothing else :>
03:31 AM miss0r: :]
03:31 AM miss0r: You do know the trick of using brass to clean a file, right?
03:33 AM MarcelineVQ: I've seen a video on it but not done it, might even have some brass left over I could try on
03:34 AM miss0r: Indeed. Just scrape in the direction of the teeth, and let the teeth form the brass. It works a charm. Copper can also be used if that is what you have on your hands
03:35 AM MarcelineVQ: lemme give it a try right now then
03:35 AM miss0r: the quality of this cast is HORRIBLE!
03:38 AM MarcelineVQ: not too surprising given the pic you linked :(
03:39 AM MarcelineVQ: tries brass and copper, was working pretty well, knocked off a lot and especially highlighted the worst spots hehe
03:39 AM MarcelineVQ: I was considering buying some lye to dissolve the stuff off, and may have to if this stuff is really stuck, but I'll be using this method to prevent this problem from now on. Thank you
03:40 AM miss0r: no problem. You can bring a file back from the death with that trick
03:41 AM MarcelineVQ: It was getting pretty bad, would have finished the job but you hate to put a tool away in that state
03:42 AM miss0r: yeah
03:43 AM miss0r: I have a 'no no' list like that. On the top is dull drill bits & dull/packed files
03:54 AM miss0r: Its not too bad a job this, i'm halfway through the turning now.. I might still earn a buck doing this
03:55 AM MarcelineVQ: halfway through the 56?
03:55 AM fragalot: MarcelineVQ: when I file alu I usually put some chalk on the file
03:55 AM fragalot: no idea if it's an old wives tale or not, but it does seem to help for me
03:56 AM MarcelineVQ: I tried soapstone one time and it just seemed to lube the file so it skid instead of bit hehe, not chalk though
03:56 AM fragalot: lol
03:56 AM miss0r: MarcelineVQ: yeah
04:53 AM jthornton: morning
04:57 AM miss0r: mornin
04:57 AM miss0r: There, all 56 done, cleaned & packed up for shipping. I think i've deserved a smoke and a soda
05:22 AM Tom_L: 47F & rain
05:22 AM jthornton: .setlocation poplar bluff, missouri

07:19 AM pink_vampire: i did alot of stuff
07:21 AM selroc: it is nice to see so hard working machinist :-)
07:29 AM -!- #linuxcnc mode set to +v by tolkien.freenode.net
08:00 AM Loetmichel: *hihi*, the apprentice just came into the workshop: "ok, goog^W Loeti! Tell me what the pinout of that thin client power pcb is!" $me (while still on the scroll saw cutting down scrap brass) "black is gnd for LED and gnd for button, brwon is button other pin, orange is led hot via a 100 ohms resistor, red is to cut off. *beep*" ... he was about the 20th today that had a question ;)
08:04 AM skunkworks_: Loetmichel, what is the pinot of the thin client power pcb?
08:05 AM Loetmichel: pinout
08:05 AM Loetmichel: <- thick fingers
08:05 AM Beachbumpete1: Loetmichel sounds like you are the guru so you get asked all the questions ;)
08:05 AM Loetmichel: and pinot is a wine
08:05 AM Loetmichel: Beachbumpete1: i am the production manager ;)
08:05 AM skunkworks_: yum!
08:05 AM gregcnc_: pinot de electrons 2001 vintage
08:06 AM skunkworks_: To early here.. maybe another hour or so...
08:07 AM Beachbumpete1: like I said ;)
08:32 AM syedmahta: May you live in peace!
08:32 AM syedmahta: We are building a CNC machine
08:33 AM syedmahta: and need assistance setting up driver and interface card connections correctly.
08:33 AM syedmahta: Can someone please assist.
08:33 AM syedmahta: Can someone please assist?
08:34 AM syedmahta: We have already checked that motor is in force
08:34 AM syedmahta: Anybody there?
08:40 AM skunkworks_: slightly...
08:40 AM skunkworks_: what are your interface card and driver?
08:48 AM syedmahta: Our interface card is 5AXIS
08:48 AM syedmahta: and driver is TB6600
08:49 AM syedmahta: Motor is 4 wire 4 Amp Sanyo Denki Japan
09:04 AM hazzy-dev: syedmahta: Are you using the parallel port or a Mesa card?
09:05 AM hazzy-dev: lol, missed him :)

11:08 AM fragalot: Hi.
11:09 AM fragalot: hey
11:15 AM gloops: EuroMillions jackpot winner comes forward to claim £121,328,187
11:17 AM SpeedEvil: Now we know why archivist was busy.
11:17 AM fragalot: lol
11:17 AM gloops: yeah hes been sitting on the winning ticket for 2 month, just to keep them guessing
11:23 AM Beachbumpete1: WOAH
11:31 AM IchGucksLive: hi all from a sunny germany
11:32 AM IchGucksLive: cool 5axis big mashine and a tb6600
11:32 AM IchGucksLive: why not a real m860
11:33 AM IchGucksLive: people are getting mashines for 3k and then a driver brig for 8USD
11:33 AM IchGucksLive: running the big mashine on 24V
11:40 AM IchGucksLive: the guy with the 5axis has been mailing me
11:45 AM IchGucksLive: Blumax, bonjour à tous en anglais
11:45 AM Blumax: IchGucksLive, bonjour :)
11:46 AM IchGucksLive: im near the French boarder FR Bitch
11:52 AM IchGucksLive: first thunder sounds
12:10 PM Blumax: IchGucksLive, The FR Bitch is better ?
12:21 PM IchGucksLive: hi to all new incomming :O
12:30 PM IchGucksLive: GN8 from germany
12:35 PM gloops: still nothing much to show, https://www.youtube.com/watch?v=8mpljMfNsyU&feature=youtu.be
12:37 PM fragalot: that sounds very chattery :/
12:38 PM rmu: lady chattery
12:38 PM gloops: yeah that tool is like a fishing hook lol, i just thought id try it
12:41 PM gloops: 6mm cut at 2500mm/min, no finishing pass, there is however no sign of missed steps yet
12:47 PM phipli: evening
12:51 PM phipli: .tell JT-Shop A friend of my dad's made this -> http://elephantandchicken.co.uk/misc/HomemadeCar.jpeg
12:51 PM theCockerel: phipli: I'll pass that on when JT-Shop is around.
12:58 PM hazzy-dev: gloopy gloops: I think that chatter has more to do with the bit you are using than the machine
12:58 PM hazzy-dev: If it can handle that without skipping steps it should do admirable with a good spiral flute bit!
01:04 PM gloops: hazzy yes it is the tool, its long and wobbly, think it was about £2
01:05 PM gregcnc_: gloops that doesn't look like 2500mm/min?
01:08 PM gloops: it does look slow to me, but thats what the code states
01:08 PM gregcnc_: feed overrides?
01:09 PM gloops: G1X75.012Y-73.163F2500.0
01:09 PM gloops: yes, i was just waiting to see if anyone would mention that gregcnc, well done
01:12 PM JT-Shop: neat
01:12 PM theCockerel: JT-Shop: 2018-04-25 - 17:49:34 <phipli> tell JT-Shop A friend of my dad's made this -> http://elephantandchicken.co.uk/misc/HomemadeCar.jpeg
01:14 PM Rab: Bluntmobile?
01:16 PM phipli: Rab - other way around
01:16 PM Rab: Does it produce blue exhaust? ;)
01:16 PM gregcnc_: Did he really like the Dehavilland Mosquito?
01:17 PM phipli: Probably, it has a 2CV engine
01:17 PM phipli: depends how much oil it is leaking
01:18 PM phipli: gregcnc_, no, he was a fan for Nathan & Costin cars https://www.google.com/search?q=Nathan+costin&client=ubuntu&hs=UmR&channel=fs&source=lnms&tbm=isch&sa=X&ved=2ahUKEwi7m5mvhNbaAhVRPsAKHcS-BdsQ_AUoAXoECAAQAw&biw=1920&bih=942
01:19 PM phipli: So built is own and then went and visited Frank Costin in it
01:20 PM Rab: I was thinking more Messerschmitt KR200.
01:21 PM gregcnc_: how thick is the skin of something like that?
01:21 PM phipli: If I remember, it is like wooden aircraft
01:22 PM phipli: it is end grain Balsa wood covered with thin ply
01:22 PM phipli: but... I'm remembering back to when I was in my early teens
01:22 PM phipli: I haven't seen it or discussed it in many years
01:24 PM phipli: so yeah, like gregcnc_ said, similar construction to the Mosquito
01:25 PM gregcnc_: I knew about the mosquito, but not about tree cars
01:26 PM phipli: It doesn't feel like it would be the most... forgiving... construction material
01:26 PM phipli: shave too much off... start again
01:26 PM phipli: I really should have a chat with my dad and find out how it was made
01:26 PM phipli: moulds?
01:27 PM phipli: I know there was a lot of glue involved
01:27 PM gloops: wow look at that car
01:28 PM gloops: whats the outer shell is that wood or just painted to look like wood?
01:29 PM phipli: plywood
01:29 PM gloops: similar method to how we built a dinghy in woodwork at school
01:30 PM gloops: (many moons ago)
01:30 PM phipli: We didn't make a dinghy at school...
01:31 PM phipli: we made coat hooks.
01:31 PM phipli: and clocks
01:32 PM gloops: well theres a yacht club on the local reservoir, they used to take school trips for a bit of canoeing and sailing, the school made some small dinghies that went to the club
01:32 PM phipli: good project - sounds like you'd learn a lot
01:32 PM gloops: we too mainly made cheeseboards and fishing float boxes etc
01:34 PM gloops: we didnt work on a dinghy from start to finish, there was always one in the room at some stage of construction so we saw it all happen and got the occassional lesson doing something for it, if we were good
01:34 PM phipli: Compared to others my school was quite good for D&T
01:35 PM phipli: but I wish we got to do more.
01:35 PM phipli: Didn't get to use the lathe even once
01:35 PM gloops: we had seperate metalwork, woodwork, tech drawing, i think it all got combined into one later
01:35 PM phipli: but they did have little mini cnc machines
01:35 PM phipli: and cutter plotters
01:35 PM phipli: and later, a small 5 axis machine they won
01:35 PM gloops: long before cnc lol
01:36 PM phipli: (that I never got to use, because the teachers didn't know how to use it and so wouldn't let us)
01:36 PM phipli: gloops, yeah, we had metalwork+woodwork, then design+"electronics", also food tech and clothes stuff
01:37 PM phipli: they didn't teach us to draw though
01:38 PM gloops: i actually liked tech drawing, it was one of those lessons that was deemed totally boring by default so you had to go along with all the kids and pretend to hate it
01:41 PM Rab: phipli, Google turned up more images here: https://m.weibo.cn/status/3927490387381032
01:41 PM gregcnc_: I signed up for metal working class, but was the only one
01:41 PM hazzy-dev: The education system is going to the dogs, losing all the tech classes
01:41 PM hazzy-dev: My last semester working on my ME degree they made it so students could take Love and Sex in place of the Fund. of Nuclear Engineering class
01:43 PM phipli: Rab, thanks for those
01:43 PM phipli: hazzy-dev, on the plus side, things like EdX exist
01:43 PM phipli: https://www.edx.org/
01:45 PM hazzy-dev: That is very true, and MIT open courses are great. If you are motivated you can get a excellent education for just the cost of your time, but you don't get that little bit of paper, which is what it is all about
01:46 PM phipli: yeah - amazing opportunity
01:46 PM phipli: gregcnc_, just remembered something else about that car
01:46 PM hazzy-dev: Ok, time to fire up the furnace and melt down about 80lbm of scrap aluminum
01:46 PM hazzy-dev: bbl
01:46 PM phipli: to maintain the centre of gravity it has flapis in the fuel tank
01:47 PM phipli: as you corner, the fuel works into the centre
01:47 PM phipli: *flapis = flaps
01:47 PM * JT-Shop has the bleeding stopped... time to get back to work
01:47 PM gregcnc_: hmm have to think about that
01:48 PM phipli: one way valves leading to the centre
01:49 PM gloops: wood is strong structurally, maybe some drawbacks for making cars but certainly a viable material
01:50 PM gloops: carts, wagons, wheels, planes ships, all been made from wood for a long time
01:51 PM phipli: houses
01:51 PM JT-Shop: phipli: btw the refrigerator is still working, a bit cold yet still tweaking the thermostat and baffle
01:51 PM phipli: not seen a wooden fridge though
01:54 PM JT-Shop: ice boxes were wood
01:56 PM JT-Shop: https://www.youtube.com/watch?v=2zSSGJT1ZNs
01:57 PM SpeedEvil: Also, consider icy balls.
01:57 PM SpeedEvil: https://en.wikipedia.org/wiki/Icy_Balls
01:57 PM theCockerel: [WIKIPEDIA] Icy Balls | "IcyBall was a name given to two early refrigerators, one made by Australian Sir Edward Hallstrom in 1923, and the other design patented by David Forbes Keith of Toronto, Ontario, Canada (filed 1927, granted 1929), and manufactured by American Powel Crosley Jr., who bought the rights to the device. Both..."
01:58 PM phipli: oh, hello Cockerel, I didn't realise you stuck your oar in for things like that
02:00 PM gloops: caravans
02:00 PM phipli: horses
02:00 PM gloops: next doors didnt stand up too well when he hit a pheasant though
02:01 PM gloops: thats aluminium sheet on wood - if it had been plywood covering would have been ok
02:01 PM phipli: his aluminium and wood horse?
02:02 PM gloops: his 4 berth chariot, top corner was demolished lol
02:07 PM gloops: well, youtube has queued uploads for some reason
02:17 PM gloops: this is 2500mm/min https://www.youtube.com/watch?v=4lPLCwitPWY
02:18 PM fragalot: i'm fairly sure that bit is not made to plunge like that
02:18 PM gloops: no not really
02:37 PM Rab: gloops, how is the tool yellow?
02:38 PM fragalot: Rab: mild steel shank with 2 "carbide" flappy bits brazed on
02:38 PM fragalot: eg. your bog standard straight flute wood bit
02:38 PM phipli: so doesn't cut in the middle of the bottom
02:39 PM fragalot: highly unlikely
02:39 PM Rab: gloops, huh, something like this? https://pillowbread.com/products/trim-router-bit
02:39 PM fragalot: but if the rpm is high enough, and the pressure is high enough, it will burn down nicely
02:40 PM phipli: this is quite an interesting channel : https://www.youtube.com/channel/UCAL3JXZSzSm8AlZyD3nQdBA
02:41 PM phipli: Things like this : https://www.youtube.com/watch?v=P73REgj-3UE&index=5&list=PLGnWLXjIDnpBBsdKZb-vy30o88SIxItp2
02:41 PM phipli: urgh. ugly url.
02:41 PM gloops: sorry went shop
02:42 PM gloops: this bit was a lot cheaper than that one Rab
02:59 PM gloops: tommorrow if i get time ill try 3500mm/min with smaller diameter tool, if thats ok, increase depth of cutt to 9mm
03:00 PM JT-Shop: one day I want to make a pump drill to start a fire with
03:01 PM fragalot: I quite like being that weirdo with the fire piston
03:02 PM phipli: I was amazed how useless people were with matches when I went to uni
03:03 PM phipli: then I remembered that most people don't have fireplaces as their main source of heat
03:03 PM phipli: like we did back home
03:03 PM phipli: and many of my friends did... because we were in the sticks
03:14 PM gloops: i come from a coal town, everyone had a coal fire
03:15 PM fragalot: I'm surprised the UK still has a lot of homes that have a coal fire
03:15 PM phipli: there isn't gas out of town
03:15 PM gloops: it doesnt, you cant burn coal anymore
03:15 PM phipli: and if you can get wood, it is almost free
03:15 PM phipli: gloops, out of town you can
03:16 PM phipli: clean air stuff is for populated areas
03:16 PM fragalot: gloops: perhaps not officially, but you can still smell it during winter in quite a lot of areas
03:16 PM gloops: yeah there are some exemptions, needs to be combustion fire, im still not sure about coal, anthracite you burn and coke, other composites
03:17 PM phipli: anthracite I think was exempt anyway
03:17 PM phipli: because it burns clean
03:17 PM phipli: but it is more expensive
03:17 PM gloops: i dont think there are any coking plants left are there?
03:17 PM gloops: yeah anthracite is welsh coal, nice stuff, so far as coal goes
03:18 PM phipli: good for keeping the stove going over night
03:18 PM phipli: we always mainly burnt wood
03:18 PM phipli: there was a fence post factory in town
03:18 PM gloops: im only about 10 mile from Orgreaves, lol, it would be unbelievable these days, they just used to push the ovens out onto the floor, great big heaps of glowing coke
03:19 PM phipli: plus a farmer used to give us hedge trimmings
03:19 PM phipli: coal / anthracite for overnight / special occasions
03:20 PM gloops: coal was everywhere here, miners got it free, more than they could use, they sold the surplus off cheap to non-mining neighbours
03:20 PM phipli: and skirting boards from pulled down buildings make /amazing/ kindling
03:21 PM phipli: hold the axe head and tap the end grain and it explodes apart like it is spring loaded
03:21 PM gloops: yes they were fine timbers they used to use
03:31 PM DocHopper: Hey Folks, looking at buzzers and wondering what a Zero-Peak Signal input type is. Anyone know? https://www.digikey.com/product-detail/en/soberton-inc/WST-1205S/433-1029-ND/479675
03:33 PM fragalot: DocHopper: 0-5V square wave
03:34 PM gloops: the worst (or best pine) that came was Parana pine, we havent had it in the UK for a long time, it was very difficult to work with
03:35 PM gloops: ordinary nails just bent when you tried knocking them in
03:35 PM gloops: i dont know if its all gone or they still use it elsewhere
03:37 PM DocHopper: fragalot: So I need to supply a square wave? I wonder why they're listed as being "Internally driven".
03:37 PM fragalot: DocHopper: normally if they are internally driven you just apply voltage
03:38 PM phipli: DocHopper, what do you need it for?
03:38 PM DocHopper: fragalot: You see me confusion?
03:38 PM fragalot: DocHopper: digikey isn't the most consistent with their classification :D
03:38 PM DocHopper: phipli: Just mounting it on a PCB i'm designing for feeding product. It's the error indication.
03:39 PM fragalot: the datasheet just mentions 5V 40mA to get 2300Hz though
03:39 PM fragalot: so.. should be easy to use
03:39 PM DocHopper: fragalot: So do you think that one is actually internally driven, or should I get one that has an input listed as "DC"?
03:39 PM gloops: just for a random factoid - parana pine is now endangered, trials have shown it to be hardy in the UK where it is being grown now
03:39 PM DocHopper: fragalot: Ya, it just confused me, so I wanted someone else to take a look at it, and make sure I'm not crazy.
03:39 PM fragalot: I suspect this one will be fine.
03:39 PM fragalot: if it's not - blame gloops :)
03:39 PM phipli: heh
03:39 PM DocHopper: fragalot: I always do.
03:40 PM phipli: DocHopper, although I'd question whether you could get 10 cheaper somewhere else?
03:40 PM fragalot: of course you could
03:40 PM phipli: as they're not exactly a product where you worry about quality
03:40 PM DocHopper: phipli: I'm at work, it's not an option.
03:40 PM fragalot: but could you get them in the same time frame?
03:40 PM phipli: they're pretty standard
03:40 PM phipli: ah
03:40 PM phipli: I understand
03:40 PM phipli: same for me
03:40 PM SpeedEvil: If you search the parametric selecrtor, you can find 9000W SOT23 transistors
03:40 PM JT-Shop: can you run a POE LAN cable 375 feet?
03:40 PM SpeedEvil: Don't trust all the fields are right
03:40 PM DocHopper: phipli: At home, I've got a $0.80usd bag of ~20.
03:41 PM DocHopper: Thanks china.
03:41 PM fragalot: SpeedEvil: I found those to be disappointing. :D
03:41 PM gloops: electicals are not my in my remit, i never said a word :)
03:41 PM phipli: DocHopper, yeah - I have a pile upstairs
03:41 PM cpresser: JT-Shop: active or passive poe? how much power?
03:41 PM phipli: I prefer the non-internal generating ones though because you can play the mario theme on them better
03:41 PM SpeedEvil: I don't think most LAN standards will work at 375ft anyway
03:41 PM phipli: https://www.youtube.com/watch?v=-kkxs_fekWM
03:42 PM fragalot: JT-Shop: doesn't that exceed your typical ethernet spec?
03:42 PM fragalot: there are coax adapters that are quite cheap for long distance
03:42 PM DocHopper: phipli: Ya, but I'm using an arduino and the timers are used for something else, so I would rather not have to bother sending it a square wave.
03:43 PM phipli: yeah, for actual sensible use it makes more sense
03:43 PM DocHopper: fragalot: You found them disappointing because of?
03:43 PM jthornton: cpresser: it for a small lan camera
03:43 PM fragalot: DocHopper: 9000W .. sot23.. One of those does not live up to spec.
03:43 PM phipli: jthornton, depends on the voltage possibly?
03:44 PM DocHopper: fragalot: I'm sorry, I do not understand.
03:44 PM jthornton: I'll see if I can find any info on the camera before I cut the cable
03:44 PM phipli: internet says 48V 802.3af POE is usually up to about 300'
03:45 PM phipli: could you put a booster in it?
03:45 PM fragalot: DocHopper: that's fine.
03:45 PM jthornton: but first time to share my monkey pickle with the chickens
03:46 PM phipli: just put ours to bed
03:46 PM cpresser: boosters in active poe somehow defeats the purpose of poe
03:46 PM jthornton: I have a 300' or so cable I'll test with it to see
03:46 PM phipli: Nonsense is still looking under the weather
03:46 PM cpresser: my guess is that it works with acive PoE
04:04 PM Deejay: gn8
04:10 PM JT-Shop: camera works on the ~300 foot cable
04:13 PM JT-Shop: now if I can just remember how to add another camera to motioneye
04:18 PM phipli: :)
04:18 PM JT-Shop: finally found the drop down box to add one
04:23 PM gloops: further googling uncovers my facebook chickens are Polish breed
04:23 PM gloops: sultans have 5 toes, polish 4, plus other things
04:24 PM phipli: gloops, frizzles?
04:25 PM gloops: they arent frizzles, they do have the head 'mop' though lol, 2 white ones are really pretty, beautiful little pure white cockerel
04:25 PM phipli: https://i0.wp.com/poultrykeeper.com/wp-content/uploads/2015/08/Chamois-and-Gold-Laced-frizzle-poland.jpg?resize=650%2C378&ssl=1
04:25 PM phipli: I love those daft looking things
04:26 PM gloops: https://www.mypetchicken.com/PicturePop.aspx?image=/images/chickenPix/Large/Studio_WhBtmPlshHn_8032_L.jpg
04:26 PM gloops: one is pretty much the same as that
04:26 PM JT-Shop: a beak with fur lol
04:26 PM gloops: yeah those are pretty extreme feathering lol
04:27 PM phipli: Our girls : http://elephantandchicken.co.uk/chickenProjects/20180414_Chickens2.jpg
04:27 PM gloops: probably not many happier chickens than yours phipli
04:28 PM phipli: The one on the left is being sad and grumpy
04:28 PM phipli: I wish she'd get better
04:29 PM phipli: she absolutely hates the stripy one - keeps biting her /really hard/
04:29 PM gloops: must be a peck order thing
04:29 PM phipli: beyond that
04:30 PM phipli: no peck, she bit her whole head the other day
04:30 PM phipli: I don't know what to do about - been happening for 6 months or more
04:31 PM gloops: strange, dont think ive known that before
04:31 PM phipli: she used to be bottom of the pecking order, but then we lost two of our birds, so she was second in command (of two)
04:31 PM phipli: I think she's scared of losing her position
04:31 PM phipli: possibly already has to the giant white chicken
04:32 PM phipli: the last thing keeping her from bottom again is picking on the other one to an extreme degree
04:32 PM phipli: but it isn't entirely working - the black and white one has the cheek to do such terrible things as /eat/
04:32 PM JT-Shop: phipli: https://www.backyardchickens.com/threads/calling-any-one-from-missouri.73271/page-882
04:32 PM gloops: possibly yeah, might be trying to reassure herself shes not going down the order
04:33 PM JT-Shop: Pinless Peepers, plastic blinders for chickens
04:33 PM phipli: gloops, shes actually showing signs of stress etc - but there is no reason for it
04:33 PM phipli: I wish she'd just relax and be friends
04:33 PM phipli: the two young ones are scared of their own shadows
04:33 PM phipli: they'll not do her any harm
04:34 PM JT-Shop: time to have a beer with the chickens
04:36 PM phipli: thanks JT-Shop - I'd consider that as long as it isn't too uncomfortable
04:37 PM phipli: I think things would get better if they just stopped fighting
04:37 PM gloops: we have one very quiet bird, same breed, same age as some of the others, she always sits away from the others, never eats with them, always at a distance from them, otherwise seems perfectly healthy, just a very quiet bird, no idea why
04:38 PM phipli: yeah, we had one like that
04:38 PM phipli: lovely bird
04:39 PM phipli: I like this photo : http://elephantandchicken.co.uk/chickenProjects/SpecCurious.JPG
04:40 PM gloops: lol, makes you wonder what they actually see, with eyes opposite
04:42 PM phipli: I'm told that they're shortsighted in one eye
04:42 PM phipli: and long in the other
04:42 PM phipli: so they turn their head one way to look at things close to, and the other for things in the distance
04:43 PM phipli: but this might be one great big internet lie
04:43 PM Tom_L: the interweb never lies!
04:44 PM phipli: case and point
04:45 PM gloops: yeah just looking at that now - mono-vision
04:45 PM gloops: also different and better colour vision
04:46 PM phipli: but crap night vision
04:46 PM phipli: (which explains why mine some times trip over things at dusk
04:46 PM phipli: or even fall off perches...)
04:49 PM gloops: hmm, they do tend to get up and sit well before it gets dark
04:51 PM phipli: Ours used to run out when they heard me get home from work
04:51 PM phipli: I'd been giving them a treat when I got home from work each day
04:52 PM phipli: but as it got further into winter it was getting dark before I was home
04:52 PM phipli: I had to stop doing that because they'd run out to me whatever time I got home, even if I was trying to go out to shut them away...
04:56 PM gloops: if i do go down late theyre usually all up off the floor, might get the odd one jump down if its still light, not known them leave perches in dark though
04:57 PM phipli: It doesn't go well :)
04:57 PM gloops: i was thinking of that old story where the fox finds the hen on the perch, but he cant reach her, so he goes round and round in circles and shes watching him, eventually she gets dizzy and falls off the perch
04:57 PM gloops: there might be a gram of fact in that
04:58 PM gloops: anyway im falling off my perch here lol, goodnight
04:59 PM JT-Shop: phipli: I think it is like anything after a while the chicken doesn't know it's different
04:59 PM JT-Shop: goodnight
04:59 PM phipli: I should too
05:01 PM phipli: night folks
05:02 PM JT-Shop: night
05:03 PM Tom_L: evening
05:06 PM Tom_L: JT-Shop, when you did that harley engrave, did you import an image or how did you go about it?
05:42 PM gregcnc_: https://youtu.be/BUye7Nv5-P8
05:43 PM JT-Shop: Tom_L: I found a dxf file and used f-engrave to V carve it
05:48 PM andypugh: Where did Grob come from? They seemed to just appear. (First I heard of them was when 3 machines turned up at work)
06:24 PM CaptHindsight: GROB-WERKE Founded: 1926, Munich, Germany
06:26 PM CaptHindsight: for some reasons their company history skips from 1939 to 1952
08:25 PM hendrik_cnc: juhu, machine working now with linuxcnc :-)
08:49 PM hendrik_cnc: https://youtu.be/92RVmgvJ2ws
08:50 PM Tom_L: always a good feeling
08:51 PM Tom_L: nice bug
08:52 PM Tom_L: err hippie van..
08:53 PM hendrik_cnc: hehe thanks :-)
08:53 PM hendrik_cnc: machine is really slow in the video but was the first movements, need first to set the right servo parameters etc.
08:59 PM Tom_L: https://www.youtube.com/watch?v=EqHV0Or4Ad8
08:59 PM Tom_L: one of my first runs
08:59 PM Tom_L: mine is stepper though
09:00 PM hendrik_cnc: yeah nice :-)
09:00 PM hendrik_cnc: now needs to learn some gladevcp basics :-)
09:01 PM hendrik_cnc: *i need
09:01 PM Tom_L: all metal from the scrap yard
09:01 PM hendrik_cnc: really nice, looks ridgid :-)
09:01 PM Tom_L: i'm not using glade
09:01 PM hendrik_cnc: this cnc was my first complex construction in fusion360
09:01 PM Tom_L: wish i had a touch screen but i don't
09:02 PM hendrik_cnc: i have, but it is not really precise
09:02 PM Tom_L: i did my cad in catia
09:02 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Column_Mill_VMC.jpg
09:02 PM hendrik_cnc: i like it :-)
09:02 PM hendrik_cnc: great work
09:02 PM hendrik_cnc: let me see if i find a rendering
09:03 PM hendrik_cnc: ah, here: https://scontent-ams3-1.xx.fbcdn.net/v/t31.0-8/28516413_1631388700274618_6582599139730678483_o.jpg?_nc_cat=0&oh=7a75857d31b568376642120f7d0a5dd7&oe=5B59D143
09:03 PM Tom_L: looks good
09:05 PM Tom_L: doing the cad saved me a few mistakes
09:05 PM hendrik_cnc: me too, maximizing useable space etc, cad is really nice
09:07 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Y_Axis_plate.jpg
09:07 PM Tom_L: especially when figuring all those holes out
09:08 PM hendrik_cnc: hehe yes
09:08 PM hendrik_cnc: can i ask basic hal programming questions? :-)
09:08 PM Tom_L: i don't see why not
09:08 PM hendrik_cnc: i have an alarm input signal of my servos and i would like to use them to halt the maschine. is this correct? ----> net alarm parport.x.y => halui.estop.activate
09:09 PM Tom_L: _from_ the servo or to it?
09:09 PM hendrik_cnc: from
09:10 PM Tom_L: looks about right then
09:10 PM hendrik_cnc: great :-)
09:11 PM Tom_L: umm, the doc says internal... just a sec
09:11 PM Tom_L: http://linuxcnc.org/docs/2.7/html/man/man1/halui.1.html
09:12 PM hendrik_cnc: hm?
09:13 PM hendrik_cnc: what does this mean for me? can't i access it?
09:13 PM -!- #linuxcnc mode set to +v by ChanServ
09:14 PM Tom_L: i used iocontrol
09:14 PM hendrik_cnc: or i use halui.program.pause
09:14 PM Spida_ is now known as Spida
09:14 PM Tom_L: that doesn't kill it though
09:14 PM Tom_L: http://linuxcnc.org/docs/2.7/html/man/man1/iocontrol.1.html
09:15 PM hendrik_cnc: did u use iocontrol.0.user−enable−out ?
09:15 PM Tom_L: iocontrol.x.emc-enable-in
09:15 PM hendrik_cnc: ah ok
09:15 PM Tom_L: probably a better choice
09:16 PM hendrik_cnc: but i have to set it to false to stop, or?
09:16 PM hendrik_cnc: Should be driven FALSE when an external estop condition exists.
09:16 PM Tom_L: set it true to enable that function
09:16 PM Tom_L: yes, false during a fault
09:17 PM hendrik_cnc: so: net alarm parport.x.y => not iocontrol.x.emc-enable-in
09:17 PM Tom_L: something like that
09:17 PM hendrik_cnc: ok great
09:17 PM Tom_L: whatever the syntax for the 'not' is in that case
09:18 PM Tom_L: i used a physical pin on mine but i think i may have a pullup on it normally. i'd have to look for sure
09:18 PM hendrik_cnc: because my alarm is connected to +5 to my card if an error occurs
09:19 PM Tom_L: for my pendant estop signal
09:19 PM Tom_L: yeah you would invert that i believe
09:19 PM hendrik_cnc: yes in my case i need to invert it
09:19 PM hendrik_cnc: @Tom_L do you recommend any plugins? :-). I found the Probe_Screen but nothing other useful stuff
09:20 PM Tom_L: are you using axis or a touchscreen interface?
09:21 PM hendrik_cnc: at the moment axis
09:21 PM hendrik_cnc: but i have not really chosen one at the moment
09:21 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/screenshot.png
09:21 PM Tom_L: that's basically what mine looks like
09:21 PM hendrik_cnc: oh many extra tabs :)
09:22 PM hendrik_cnc: did u add the spindle widget with gladevcp?
09:22 PM Tom_L: i never use em :)
09:22 PM Tom_L: yes
09:22 PM Tom_L: all the right column is
09:23 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/NEW_MILL/
09:23 PM Tom_L: should be in there somewhere
09:23 PM Tom_L: probably the postgui.hal
09:23 PM Tom_L: and some mixed in the others a little
09:23 PM Tom_L: display.xml
09:24 PM hendrik_cnc: great thanks :)
09:29 PM hendrik_cnc: @Tom_L "cycle times > overall" do you save the complete life cycle of your machine or just for the job?
09:29 PM Tom_L: job
09:30 PM Tom_L: i wanted to compare it to the times my cad said so i could adjust the cad a little but it's pretty close
09:30 PM Tom_L: and i just left it in
09:30 PM hendrik_cnc: ah ok :-)
09:31 PM Tom_L: tool number is quite handy
09:31 PM Tom_L: almost wish i had work offset in there too
09:31 PM Tom_L: G54 etc
09:32 PM hendrik_cnc: oh yes this is really handy
09:33 PM Tom_L: the 0.0 below the speedometer is also rpm
09:34 PM hendrik_cnc: https://www.irccloud.com/pastebin/goEuMedP/
09:34 PM hendrik_cnc: this is really handy too :p
09:34 PM Tom_L: yeah
09:35 PM Tom_L: i don't use that as much though
09:35 PM Tom_L: i thought i would
09:35 PM hendrik_cnc: where can i find <halpin>"but-work-zero"</halpin> ?
09:36 PM hendrik_cnc: ah found it
09:36 PM Tom_L: display.xml, postgui.hal and new_mill.ini have most of it i believe
09:38 PM Tom_L: i think that calls a subroutine that just sends the axis to the work offset zero
09:40 PM hendrik_cnc: yepp, helped me a lot your stuff, thank you!
09:42 PM Tom_L: o<work_zero> sub
09:42 PM Tom_L: G90
09:42 PM Tom_L: G0 Z0
09:42 PM Tom_L: G0 X0 Y0
09:42 PM Tom_L: o<work_zero> endsub
09:42 PM Tom_L: m2
09:44 PM Tom_L: but with that said, i don't touch my tools off the top of the material... rather a distance above it
09:45 PM hendrik_cnc: @Tom_L do i need to install glade to create a new ui file?
09:45 PM hendrik_cnc: or do i use gladevcp?
09:45 PM Tom_L: no idea
09:45 PM Tom_L: create a new widget?
09:46 PM Tom_L: http://linuxcnc.org/docs/2.7/html/gui/gladevcp.html
09:46 PM Tom_L: those are available
09:46 PM hendrik_cnc: i have no glade-gtk2 in the repository because i am running debian stretch
09:47 PM Tom_L: is that 9?
09:47 PM Tom_L: i just installed 9 on a box in the office to test with
09:47 PM hendrik_cnc: yes 9
09:48 PM Tom_L: but i haven't tried to run anything yet
09:48 PM hendrik_cnc: i have it working on my cnc
09:48 PM Tom_L: preempt?
09:48 PM Tom_L: or rtai?
09:48 PM hendrik_cnc: yes
09:48 PM hendrik_cnc: preempt
09:48 PM Tom_L: ok
09:48 PM Tom_L: same here
09:48 PM Tom_L: i'm using rtai on the mill
09:49 PM Tom_L: some old debian version
09:49 PM hendrik_cnc: ok i needed to install package glade
09:49 PM Tom_L: forget which one
09:54 PM hendrik_cnc: @Tom_L do you know where the normal linuxcncdir sits?
09:54 PM hendrik_cnc: i am searching its scripts folder
09:54 PM Tom_L: yeah but i forget off hand
09:55 PM Tom_L: i gotta go get some sleep, gotta get up at 3 tomorrow
09:56 PM hendrik_cnc: gn8
09:57 PM Tom_L: look in /usr/bin maybe
10:39 PM hazzy-dev: Had a very close call this afternoon at my buddy's recycling shop
10:40 PM hazzy-dev: I was melting down old aluminum and copper PC heat-sinks and an oil filled heat sink had some how snuck into the batch
10:41 PM hazzy-dev: The instant it hit the molten metal in the furnace it burst and sent most of the content of the furnace in all directions
10:41 PM MarcelineVQ: :(
10:41 PM hazzy-dev: Cars in the parking lot 30ft away were sprinkled with al
10:43 PM hazzy-dev: I am ok, but as I was leaning partially over the furnace I got a pretty good amount in my face and chest
10:44 PM MarcelineVQ: scary stuff
10:45 PM hazzy-dev: Very scary, I am still shaky and it happened about 3hr ago
10:46 PM hazzy-dev: I think I am lucky as I had a good bit of stubble, and that kept me from getting burned any worse on the face
10:47 PM MarcelineVQ: could be a good excuse to make something that does the dropping in for you, like how you'd feed a monster in a movie :X
10:50 PM MarcelineVQ: something as simple as a lid for the furance with a little box on it that drops the stuff in when the lid closes
10:55 PM hazzy-dev: MarcelineVQ: Yes we really do need something like that, if just for safety
10:55 PM hazzy-dev: He is getting a much bigger furnace that can do a 200-300 lbs at a time, and that will certainly have a chute of some sort
10:56 PM hazzy-dev: We preheat everything to a couple 100 degrees to make shur there is no watter in it, but as we learned today that is not enough!
10:56 PM MarcelineVQ: of if he's upgrading anyway one of those munchers than pre-chews metal would reduce a lot of hazard
10:56 PM MarcelineVQ: plus cut metal time
10:56 PM MarcelineVQ: melt
11:06 PM hazzy-dev: That is a good idea, I am surprised he does not have something like that already. I know a lot of recycling places have a grinder to reduce the volume
11:11 PM jdh_ is now known as jdh
