12:02 AM jesseg: pink_vampire, you mean like t his? http://www.hi-q.net/products/air-flow-calibrators-adapters/v-flo-series-in-line-venturi-flow-meters/default.html
12:06 AM jesseg: I'll bet that thing is excessively expensive.
12:06 AM XXCoder: maybe could make one using bend sensor
12:06 AM XXCoder: and some raspi to detect it and output proper values
12:19 AM IchGucksLive: morning from germany
12:20 AM Tecan: "Researchers at Zhejiang University in China have shown that they can encode commands in high frequency sound that are still recognized by voice assistants. They take a regular human voice and use it to modulate an ultrasound signal"
12:20 AM fragalot: Hi
12:21 AM ziper: bye
12:21 AM Tecan: microphone and phase shifted sound to fix it if you hear that happening to you ?
12:35 AM IchGucksLive: im off 2 garden Till later
02:09 AM Deejay: moin
04:07 AM pink_vampire: jesseg: no, i mean to just in indicator to make sure there is a coolant flow in the spindle
04:44 AM gloops: 28C
04:44 AM gloops: record breaking for UK in May maybe
04:45 AM XXCoder: pink_vampire: ya I remember one design
04:46 AM XXCoder: its very simple, it uses floater with metal on it and sensor for that
04:47 AM XXCoder: cant find specific one I saw
04:48 AM XXCoder: maybe this can work. https://www.youtube.com/watch?v=am3oan8IW_4
05:22 AM pink_vampire: no. i will need to google it more
05:22 AM pink_vampire: I need some sleep
05:25 AM XXCoder: night
05:32 AM adamj12b: Has anyone had success with the LOG output? I canr open the file (LOGOPEN,test.txt) without the system throwing an error of "unknown word where unary operation could be"
05:38 AM jthornton: works for me
05:38 AM jthornton: you must have a typo
05:43 AM adamj12b: Do you have to leave the LOGOPEN and LOG inside the ()?
05:44 AM jthornton: http://linuxcnc.org/docs/2.7/html/gcode/overview.html#_logging
05:46 AM jthornton: why do people email me when their shipment is delayed by the USPS?
05:56 AM jthornton: why do 90% of putube videos spend a long time yacking about crap and not getting on with the program
06:04 AM XXCoder: longer video more money
06:04 AM jthornton: how do they make money from the video?
06:05 AM XXCoder: adverts
06:05 AM XXCoder: they dont till I think views go over certain number
06:05 AM XXCoder: 2,000?
06:05 AM XXCoder: and certain number of subs also?
06:05 AM jthornton: lol I have ublock so I never see the ads lol
06:05 AM XXCoder: youtube plus for me
06:06 AM XXCoder: I enable ads only for my subbed channels
06:06 AM XXCoder: so they actually earn money
06:06 AM XXCoder: unsubbed I dont care
06:14 AM jthornton: subbed?
06:14 AM rmu: subscribed presumably
06:15 AM XXCoder: yeah
06:15 AM gregcnc_: people like to talk
06:16 AM gregcnc_: what's amazing is that other people have time to watch
06:16 AM XXCoder: I LOVE some channels thats all talk
06:16 AM XXCoder: like issac
06:16 AM XXCoder: https://www.youtube.com/channel/UCZFipeZtQM5CKUjx6grh54g
06:16 AM XXCoder: deep topics about various stuff, majority about future
06:17 AM gregcnc_: i'm not into stuff like that
06:18 AM XXCoder: well I also sub to various machinist channels, some offbeat channels
06:18 AM XXCoder: like that channel where guy make knives out of weird material, most recent being carbon fiber
06:19 AM rmu: PBS Space Time
06:25 AM jthornton: I wonder if the view count is for times completely viewed or just someone going to that page and seeing how crappy the video is and leaving a few seconds later lol
06:26 AM gregcnc_: there is a critetria, i forget what it is
06:27 AM XXCoder: jthornton: I think time of view is what also factor
06:27 AM XXCoder: thats why they buffer intro and outro
06:27 AM gregcnc_: buffer?
06:29 AM XXCoder: bah too tired to use right words
06:29 AM XXCoder: add time to
06:29 AM gregcnc_: ~30 seconds constitutes a view
06:29 AM XXCoder: some stupid logo appears, so on
06:30 AM gregcnc_: any more than 5sec intro I close
06:30 AM gregcnc_: not worth it
06:30 AM jthornton: me too
06:30 AM XXCoder: I just hit right arrow couple times
06:30 AM XXCoder: if intro is 20% of video I dont sub to channel, assuming I even like channel
06:47 AM phipli: jthornton - updated the fan controller to add a graphical status image
06:47 AM phipli: http://elephantandchicken.co.uk/temperature/index.html
06:48 AM phipli: means that I can upload it to the server same as the graph
06:48 AM jthornton: cool
06:48 AM phipli: Figure it is reading a couple of degrees high - will need to calibrate it
06:49 AM phipli: I drew the svg image in inkscape, opened it in a text editor and replaced the text with things like %TEMP%
06:50 AM phipli: my code then reads the image as a file and before sending it on to the computer that requested it, substitutes %TEMP% for the temperature
06:50 AM phipli: *as a text file
06:54 AM jthornton: cool
07:10 AM phipli: Right. Off to the shop to fetch some wood
07:10 AM phipli: laters

08:57 AM TurBoss: Hola
09:06 AM JT-Shop: hi
09:22 AM phipli: afternoon
09:22 AM phipli: fixed my fence
09:47 AM phipli: .weather
09:47 AM theCockerel: Yahoo! Weather - Derby, England, GB: Sunny, 24°C (75°F), Humidity: 44%, Light breeze 3.1m/s (↑)
10:25 AM jdh: wow. sunny and warm in england?
10:28 AM IchGucksLive: hi all
11:03 AM mtpocketscnc: I have some questions on if there is a way to setup/build something for my cnc to trace large profiles. I was thinking something like gcode-ripper except working in the x and y instead of z. I'm not too good at programming yet but would be willing to read or do as much work as can if someone is able to point me in the right direction
11:09 AM cradek: linuxcnc has complex enough probing capabilities in gcode to do tracing. the demo program smartprobe.ngc traces along a path in a grid - tracing around the outside of an outline can be done the same way
11:11 AM cradek: I've probed simple (convex) shapes by (manually) circumscribing a circle and probing inward (to the origin/center) from equally spaced points on the circle
11:11 AM cradek: walking along the edge would also be possible, just more programming
11:13 AM mtpocketscnc: was thinking on some sort of bounding box idea myself like you said with probing from a circle
11:18 AM mtpocketscnc: so I just had a look at smartprobe.ngc. am i right in saying that it is similar to gcode-rippers probe-n-cut
11:18 AM cradek: I don't know what gcode-ripper is
11:19 AM cradek: if your shapes are convexish it seems like you could do better at finding the next probe start point than going out to a circle
11:19 AM cradek: go out a bit, move over a bit along a tangent
11:20 AM cradek: you could even use your last two probe points as the "move over" vector, and that'll give good results if the shape is fairly continuous
11:21 AM cradek: and if that fails you could revert to the circumscribed circle
11:21 AM cradek: (fails by hitting the part when you think it should be in air)
11:21 AM cradek: you have to code this carefully to avoid breaking your probe on a weird shape
11:23 AM mtpocketscnc: let me see if I can give a link to pic to explain better
11:24 AM phipli: .weather
11:24 AM theCockerel: Yahoo! Weather - Derby, England, GB: Sunny, 25°C (77°F), Humidity: 42%, Light breeze 3.1m/s (↑)
11:31 AM fragalot: Hi
11:31 AM Tom_L: .weather
11:31 AM theCockerel: I don't know where you live. Give me a location, like .weather London, or tell me where you live by saying .setlocation London, for example.
11:31 AM Tom_L: but i want it all!
11:32 AM jdh: .weather earth
11:32 AM theCockerel: jdh: No forecast available. Try a more specific location.
11:32 AM fragalot: Tom_L: here it's ungodly sunny
11:32 AM Tom_L: .weather mars
11:32 AM theCockerel: Yahoo! Weather - Mars, NW, DE: Sunny, 26°C (78°F), Humidity: 27%, Moderate breeze 6.3m/s (←)
11:32 AM Tom_L: nice
11:33 AM jdh: who is in wichita?
11:33 AM Tom_L: me
11:33 AM jdh: what is typical weather for june 2
11:33 AM Tom_L: generally nice
11:34 AM Tom_L: evening tornados to keep you on your toes
11:34 AM Tom_L: it's not been a typical year though
11:35 AM jdh: here either.
11:35 AM skunkworks: we went from 1 foot of snow to 70deg weather in about a day
11:36 AM Tom_L: you comin to town?
11:37 AM phipli: baking hot here today
11:37 AM phipli: UK has broken temperature records for the bank holiday weekend
11:37 AM jdh: going to Emporia
11:37 AM mtpocketscnc: https://pasteboard.co/Hk6aWKb.jpg Not the greatest example but it's what i've got here
11:37 AM Tom_L: oh that's right..
11:37 AM phipli: down side is it draws all the naked people out of their houses with their bbqs and music
11:37 AM skunkworks: is thre a fest?
11:38 AM Tom_L: jdh, figure out where you're gonna stay?
11:38 AM mtpocketscnc: I would like to probe the edges so that I can make a backing that follows profile
11:38 AM jdh: finally got holiday inn. like $270/night
11:38 AM Tom_L: seems like alot
11:39 AM mtpocketscnc: I have other uses too but this is one of the examples I am thinking of
11:41 AM jdh: usually 75/night
11:42 AM IchGucksLive: hi
11:45 AM IchGucksLive: holzjunkie, voll die hitzewelle
11:45 AM mtpocketscnc: hello
11:46 AM mtpocketscnc: how are you today IchGucksLive
11:51 AM IchGucksLive: oh i first did chip some wood with a axe
11:52 AM IchGucksLive: then i mounted 4 Z Axis HGH
11:52 AM IchGucksLive: after i broke a M5 Treadbid
11:52 AM IchGucksLive: i choped a big tree
11:52 AM IchGucksLive: so it is fine
11:53 AM IchGucksLive: I Also hate students that dont do there job
11:54 AM IchGucksLive: milling 12x4x4 pockets 4x4mm is boring i know
11:54 AM IchGucksLive: but half are other masurments
11:54 AM IchGucksLive: he has been told bevor open the CLAMP look if the plate running thrue Fits
11:55 AM mtpocketscnc: beautiful day here in wisconsin happy winter's over
11:55 AM gregcnc_: land of cheese
11:55 AM IchGucksLive: mtpocketscnc, he might fitet one plate for all 12 clamps
11:56 AM mtpocketscnc: cheese heads and packer fans
11:56 AM IchGucksLive: greenbay
11:56 AM gregcnc_: considering leaving almost california aka Illinois for WI
11:57 AM IchGucksLive: how is the Hawai breaking apart
11:57 AM IchGucksLive: imagin a Vulcano erupts on your Potato field
11:57 AM IchGucksLive: like iceland
11:58 AM Tom_L: or Mt St Hellen
11:58 AM IchGucksLive: Were Europ and North america meets
11:58 AM IchGucksLive: Tom_L, how high did this grow since
11:59 AM Tom_L: i don't know
11:59 AM gregcnc_: monday trivia
12:01 PM Tom_L: i guess it's been 10 yrs since that happened
12:14 PM mtpocketscnc: gregcnc you aren't one of them chicago guys that blows my doors off while while on vacation here are ya lol
12:19 PM IchGucksLive: im off Sundown a nice day is closing with a Beer on the Veranda
12:35 PM gregcnc_: no way i'd live in chicago, but speed limit signs are suggested minimums around here
12:36 PM holzjunkie: IchGucksLive: typical german a few day´s good weather and it goes on: to hot to sunny ......
12:38 PM mtpocketscnc: yeah I get a kick out of me doing 70 down free way and chi town people going by like I'm standing still. 90 seems to be the average speed ha ha
12:39 PM Wolfmetalfab is now known as Wolf__
12:39 PM gregcnc_: posted is now 70 from the stateline south to the airport
12:41 PM mtpocketscnc: yeah we got bumped up a bit from 65 to 70 about 2 or 3 years ago
12:44 PM gregcnc_: what area are you in?
12:44 PM mtpocketscnc: used to speed alot in my younger days. Now that i'm starting to get old and crotchety I drive speed limit everywhere I go and swear under my breath about kids
12:45 PM mtpocketscnc: right near fox valley appleton oshkosh greenbay. I live out in the sticks a bit though
12:47 PM gregcnc_: quite a ways, last time i was that way was for a quick Oshkosh Airventure visit
12:48 PM mtpocketscnc: yep made the EAA once or twice myself. great shows
12:49 PM mtpocketscnc: paid for ride once in old biplane. guy didn't tell me he planned to do a loop. just about soiled myself
12:50 PM gregcnc_: lol, that would be a surprise
12:52 PM mtpocketscnc: yeah when EAA goes on we even get pretty neat show out where I am (about 45 min away) planes in the sky all day long before airventure and a bit after
12:53 PM mtpocketscnc: been facing a big chunk of wood all this time I've been yacking. I need to build 48" planer
12:56 PM gloops: not practical
12:56 PM gloops: a 100mm horizontal cutter block on a cnc router might be though
12:59 PM mtpocketscnc: your saying works kinda like sawmill except horizontal?
12:59 PM gloops: plane it in passes
01:00 PM mtpocketscnc: Example pic? I tried looking up on google but got alot of scattered results
01:01 PM gloops: you get the block from an electric hand planer, mount it on the z axis with a motor - away you go
01:01 PM mtpocketscnc: oh yeah!
01:01 PM mtpocketscnc: my buddy said that too
01:02 PM mtpocketscnc: like 4 or 6 inches in a pass or something instead of 1/8
01:03 PM mtpocketscnc: BBL gotta put my youngen down for nap
01:03 PM gloops: right, you can get wide cutters for vertical router for surfacing, but horizontal is far more efficient
01:05 PM gloops: there were some vids on youtube cant see them now
02:16 PM gloops: http://www.easycomposites.co.uk/#!/patterns-moulds-and-tooling/pattern-making/high-density-polyurethane-foam-block.html
02:16 PM gloops: stuff like that would be ideal, but that costs far too much like that
02:25 PM ziper: whats this about
02:26 PM gloops: this channel ziper?
02:26 PM ziper: the foam
02:26 PM gloops: oh foam, for machining
02:26 PM ziper: yeah
02:26 PM ziper: I need to shape one to use as a fiberglass core for a daggerboard
02:27 PM gloops: whats a daggerboard?
02:27 PM gloops: surfboard?
02:27 PM ziper: its like a keel
02:28 PM gloops: cant you make the fibreglass case and fill it with expanding foam?
02:29 PM ziper: expanding foam is too weak
02:29 PM ziper: and I would then still need to make a mold to make the case
02:31 PM gloops: so youre using the foam to carve the plug to take the mold from, right
02:31 PM gloops: yes its good for that
02:31 PM ziper: nope I'll lay the glass right over it
02:32 PM gloops: rough exterior
02:32 PM gregcnc_: what else are people using?
02:33 PM ziper: gloops, its not bad with vacuum bagging
02:33 PM gloops: gregcnc to make a plug, wood, chicken wire, plaster etc
02:33 PM ziper: and i'd probably have to fair it anyway
02:33 PM ziper: yeah cedar is my backup
02:33 PM gregcnc_: if you need a high density foam what else can you use?
02:34 PM SpeedEvil: wood
02:34 PM gloops: gregcnc high density foam seems suitable for outdoor sign work, its too expensive at those prices though
02:34 PM gloops: i could look into pouring the foam but for high density it gets a bit tricky i think
02:34 PM gregcnc_: signs? from that stuff is a bit nuts
02:35 PM gloops: why is that?
02:35 PM gregcnc_: as far as price
02:35 PM gregcnc_: do you have that light MDF over there?
02:35 PM CaptHindsight: http://www.jollyrogertelco.com/biz-bots takes robocalls for you and wastes the callers time
02:36 PM gloops: we have the light brown mdf
02:36 PM gloops: the green mdf
02:36 PM gloops: and that new stuff thats waterproof - its about £100 a sheet or more
02:38 PM gloops: http://www.avonply.co.uk/Client%20Area/ASP/Tricoya.aspx
02:39 PM gloops: soon everything will be mde from that
02:39 PM gloops: even cars
02:40 PM gregcnc_: wtf is ironmongery
02:41 PM gloops: ironmongery? its like, hardware haha
02:41 PM CaptHindsight: obviously a mongery made from iron
02:41 PM gloops: you go to the ironmonger
02:41 PM CaptHindsight: https://en.wikipedia.org/wiki/Ironmongery
02:41 PM gloops: thats pronounced iron - munger
02:42 PM gregcnc_: hardware store?
02:42 PM CaptHindsight: yes
02:42 PM gloops: yeah like that
02:42 PM methods_: i prefer arms dealer
02:42 PM methods_: lol
02:42 PM CaptHindsight: those funny Brits
02:43 PM gloops: you can buy hinges, nails, buckets, bolts all that kind of stuff
02:43 PM gregcnc_: somehow I made it this far never running into that term
02:44 PM CaptHindsight: well even the Brits find themselves speaking too properly and have to mix it up
02:44 PM gloops: i guess you live in a frontier kind of place gregcnc
02:45 PM methods_: https://phys.org/news/2018-05-scientists-strong-super-tough-carbon-sheets.html
02:46 PM gloops: hardwood is frightfully expensive here
02:46 PM CaptHindsight: jthornton: JT-Shop: they contact us since they think we have some magical control over the package delivery service
02:47 PM gloops: a graphite mine opened near one of my favourite coastal places here
02:48 PM CaptHindsight: https://www.babbel.com/en/magazine/british-accents-cockney/
02:48 PM CaptHindsight: before there was Rap ^^
02:48 PM gloops: pine is the standard timber on sale, pine is good for many things, but not outdoor signs really
02:48 PM ziper: why is solidworks such a piece of shit, point 7 is obviously NOT coincident https://puu.sh/AhUbn/4d59c10515.png
02:48 PM gloops: CaptHindsight London has gone
02:49 PM gloops: that isnt London anymore, its some foreign city with english buildings
02:49 PM gloops: there are no cockneys now
02:49 PM CaptHindsight: it might be
02:49 PM fragalot: ziper: concident tangent :P
02:50 PM CaptHindsight: or sometimes the devs just get bored and introduce things like this to give us all something to question and ponder
02:50 PM fragalot: job security
02:50 PM CaptHindsight: offset coincident
02:51 PM ziper: fragalot, CaptHindsight I dont get it
02:52 PM fragalot: ziper: the endpoint of the line is on a tangent with the part of the curve you selected
02:52 PM gregcnc_: uh yeah SW does that
02:52 PM fragalot: perhaps that's what it is locking on to?
02:52 PM ziper: fragalot, but I can drag the point literally anywhere
02:52 PM gregcnc_: I get that with airfoils too
02:52 PM ziper: I feel like i'm beating my head against a wall trying to make a foil in sw
02:53 PM gregcnc_: imported curve?
02:53 PM ziper: I could modify the points before I import them to get the line down the centerline
02:53 PM ziper: but I would still not be able to fucking scale the thing
02:53 PM gregcnc_: why can't you scale?
02:54 PM ziper: there is nowhere to dimension it from so I have to use the scale tool which is really annoying
02:54 PM ziper: and there is the fact that there is a gap at the trailing edge after importing it
02:55 PM ziper: i'm going to take a nap
02:55 PM gloops: solidworks should be more sophisticated than that surely
02:55 PM gregcnc_: add vertical lines from origin to close the TE
02:55 PM gregcnc_: scale works fine for me
02:55 PM gloops: draw it from scratch, its only a mirrored curve, make a vector in inkscape
02:56 PM gregcnc_: uhm no
02:56 PM ziper: rest in piece the laminar flow
02:57 PM ziper: gregcnc_, do you know of any better software to use or is this just the best it gets
02:57 PM gregcnc_: it's what I use
02:57 PM ziper: I feel like there ought to be better controls for such a sophisticated program
02:59 PM gregcnc_: I haven't used much else in a long time
02:59 PM gloops: tricoya mdf has a 50 year guarantee, 25 years in the ground
02:59 PM gregcnc_: what are you building?
02:59 PM gregcnc_: ziper^
03:03 PM fragalot: ziper: you could use autodesk instead if you don't want the coincident bug... it just all out crashes instead.
03:03 PM ziper: gregcnc_, boat hydrofoils, in this case a daggerboard
03:03 PM CaptHindsight: friends don't let friends use autodesk
03:04 PM gregcnc_: i've drawn some hydrofoils stuff for a client
03:04 PM gloops: you can do that in freecad
03:05 PM CaptHindsight: Creo is for funky artsy curvy stuff
03:05 PM gloops: Ichs has probably got a youtube vid just making hydrofoils in freecad
03:05 PM CaptHindsight: but with dimensions
03:06 PM gregcnc_: a lot of model airplanes done in SW
03:07 PM CaptHindsight: can't you just cancel the constrant in SW?
03:07 PM gloops: or model it in blender - still the best
03:07 PM CaptHindsight: just un-coincident it
03:07 PM ziper: I want to bisect the foil section
03:07 PM gregcnc_: that' can be fixed, I don't remember the procedure i use off the top of my head
03:08 PM gregcnc_: draw horizontal from origin, and trim
03:08 PM CaptHindsight: why sometimes you have to watch a demo by a SW dev
03:08 PM CaptHindsight: to get inside their heads and see how they imagine parts should be created
03:09 PM gregcnc_: yeah it help to know how SW thinks
03:09 PM CaptHindsight: same for CATIA, NX etc
03:09 PM ziper: I can't even measure the length of the foil because there is nowhere on the leading edge to click
03:10 PM ziper: so I dont know what to scale it by
03:10 PM CaptHindsight: ever draw some parts for an assembly and it wants to automatically mate the opposite sides of parts you created?
03:10 PM CaptHindsight: not the sides you want to mate
03:10 PM gregcnc_: why measure
03:10 PM ziper: the trim worked
03:10 PM gregcnc_: didn't you import a 1 unit long curve?
03:11 PM gregcnc_: now measure the line if you need it
03:11 PM ziper: yeah
03:11 PM ziper: thanks
03:18 PM Deejay: gn8
03:20 PM CaptHindsight: is Deejay on dialup?
03:21 PM CaptHindsight: ponders the use of the bot here for fun and amusement
03:21 PM CaptHindsight: naaaah
03:22 PM gloops: does anyone know deejay? ive rarely seen him speak
03:22 PM CaptHindsight: fragalot: https://medium.com/@aerosint/how-to-make-cheap-scalable-multi-material-3d-printing-a-reality-d298fa1f76da
03:23 PM CaptHindsight: more articles from the SLS more than one powder at a time people ^^
03:24 PM CaptHindsight: you can see how low res it is here: https://cdn-images-1.medium.com/max/1600/0*dj93rkAb5fH4cfNT.
03:24 PM ziper: here is my lame part http://puu.sh/AhVAv/ce5f34c308.jpg
03:24 PM fragalot: CaptHindsight: well,.. it IS a prototype concept :P
03:24 PM CaptHindsight: fragalot: oh look at how poor the Z is!!
03:25 PM fragalot: I like the smears
03:25 PM CaptHindsight: nearly useless
03:25 PM fragalot: think of the material certificates
03:25 PM XXCoder: jeez. 8 more meltdown tupe bugsfound
03:25 PM fragalot: for aerospace parts
03:25 PM XXCoder: *type
03:26 PM CaptHindsight: fragalot: there was another post where they could not locate any applied patent
03:26 PM fragalot: lol
03:27 PM CaptHindsight: oh wow, the black bar is 1cm, not 1mm!!
03:27 PM fragalot: yeah :D
03:30 PM CaptHindsight: "
03:30 PM CaptHindsight: BS patent pending, nothing can be found. But great technology, hope you don't get it stolen."
03:32 PM CaptHindsight: I'm going to patent laying down 1 layer of powder followed by laser sintering the layer, followed by a cleaning pass by a lint roller, wash rinse repeat
03:32 PM CaptHindsight: so don't tell anyone
03:35 PM ziper: lol
03:36 PM fragalot: if it's publicized, can you still apply for the patent after?
03:36 PM fragalot: because i'm fairly sure you can't
03:37 PM fragalot: hehe. patent pending.. in their outbox.
03:38 PM gloops: patenting it might stop people here making it
03:38 PM gloops: but not elsewhere
03:38 PM CaptHindsight: fragalot: all depends on the patent examiner
03:39 PM CaptHindsight: they often are too "busy" to notice these sorts of things
03:39 PM CaptHindsight: and once it's granted they rarely revoke them
03:39 PM fragalot: CaptHindsight: the patents often get thrown out at a later date in .eu
03:39 PM CaptHindsight: often/rarely
03:39 PM fragalot: often in comparison to the US
03:40 PM CaptHindsight: maybe more there than here
03:40 PM fragalot: Anyway - i'm off to this thing I plan on patenting with a large soft flat surface containing 2 smaller soft flat surfaces, covered by yet another soft flat flexible surface
03:40 PM fragalot: gnite!
03:41 PM CaptHindsight: it's interesting that rather than demo the actual printer they are marketing the process with articles like this
03:41 PM fragalot: depends on their business model
03:41 PM fragalot: they may be interested in selling the idea more than the device
03:41 PM fragalot: or trying to get more funding
03:41 PM fragalot: anyway -- ttyl :)
03:41 PM CaptHindsight: since they can't make one good enough for actual applications
03:41 PM CaptHindsight: hasta banana
03:44 PM CaptHindsight: While we haven’t yet achieved the same minimum feature size as the pipette based systems, our process may easily be 10–100x faster than a single-pipette system.
03:44 PM CaptHindsight: heh single pipette, there's the clue
03:45 PM CaptHindsight: like how a 1000 nozzle printhead is faster than a single ink pen
03:46 PM CaptHindsight: so they might be able to patent their low res drum transfer tech..
03:47 PM CaptHindsight: but not a multi-pipette system
03:48 PM CaptHindsight: so multi-pipette has higher deposition rates and higher/better res (smaller feature sizes)
03:57 PM miss0r: I have a 1.5mm HSS+CE endmill, two flute. I'm cutting brass. What would you guys recommend for as DOC when the cutter is fully engaged? (only running 4000rpm here)
03:57 PM miss0r: HSS+CO*
04:45 PM Motioncontrol: hi. exist a software for convertfanuc program in linuxcnc rs274 ?
04:47 PM jesseg: Is it in g code already?
04:47 PM Motioncontrol: yes , i want conver a spiral macro fanuc in linuxcnc
04:48 PM Motioncontrol: is hard because fanuc use goto
04:50 PM gregcnc_: http://linuxcnc.org/docs/2.7/html/gcode/o-code.html
04:51 PM Motioncontrol: yes i understand it , but linuxcnc not have goto for jump in another part the program
04:54 PM gregcnc_: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Oword
04:57 PM gregcnc_: I wish I knew more. it's not something I use
04:57 PM Motioncontrol: this is the file : https://pastebin.com/m9mqB54D
05:00 PM gregcnc_: maybe this helps http://wiki.linuxcnc.org/cgi-bin/wiki.pl?G12-13
05:01 PM CaptHindsight: https://www.cnczone.com/forums/tormach-personal-cnc-mill/283846-tormach.html
05:10 PM CaptHindsight: this post sums it up
05:10 PM CaptHindsight: https://en.industryarena.com/forum/showthread.php?t=283846&p=1770174&viewfull=1#post1770174
05:12 PM CaptHindsight: https://www.mail-archive.com/emc-users@lists.sourceforge.net/msg53371.html
05:14 PM CaptHindsight: and in the immortal words of andypugh https://www.mail-archive.com/emc-users@lists.sourceforge.net/msg53368.html
05:15 PM gregcnc_: I don't think he needs goto specifically for what he's doing, I think the example does what he wants.
05:15 PM gregcnc_: i've done some loops with fanuc, but not with linuxcnc
05:16 PM Motioncontrol: this the problem, is good thing convert more fanuc macro in linuxcnc, but is hard
05:17 PM andypugh: Well, part of the problem is _what_ do you goto?
05:17 PM CaptHindsight: the more you do it the easier it gets :)
05:17 PM andypugh: RS274NGC ignores line numbers.
05:17 PM andypugh: I guess you could use O100 GOTO 200
05:17 PM andypugh: and O200 GOTO_TARGET
05:18 PM CaptHindsight: if we had more paid developers then maybe we could have more interpreters
05:19 PM andypugh: We have two
05:19 PM andypugh: And they are pluggable
05:19 PM andypugh: A 100% Fanuc-compatible interpreter would actually be fairly possible.
05:20 PM Motioncontrol: the problem is : goto jump at another part the program up or down the goto . o100 call jump at sub, but retur after call.
05:21 PM Motioncontrol: how can use fanuc style andypugh
05:23 PM cradek: (I didn't look at your file but) to make a spiral in ngc you might consider using polar coordinates: https://github.com/LinuxCNC/linuxcnc/blob/master/nc_files/spiral.ngc
05:24 PM andypugh: Motioncontrol: You can’t. But somone could write an alternative interpreter. It is just that nobody has.
05:26 PM Motioncontrol: Hi Chris . yes i know it. the problem is search a system for convert the fanuc macro. when use the linuxcnc machine, more people question : can use fanuc program in linuxcnc ? the answer is NO. the idea is convert some fanuc macro for general use the machine and create a metode for convert it in linuxcnc
05:28 PM andypugh: Motioncontrol: There is already an alternative interpreter for which this is a valid program: https://github.com/LinuxCNC/linuxcnc/blob/master/configs/sim/axis/canterp_example.can
05:29 PM Motioncontrol: andypugh, how is canterp ?
05:29 PM andypugh: Is the Fanuc “Goto” a G-code, or does it look like “GOTO” ?
05:31 PM andypugh: Motioncontrol: Canterp is just a very simple alternative intepreter (it basically just converts the low-level commands that the existing interpreter sends to the motion controller into the same commands)
05:31 PM Motioncontrol: andypugh, more interesting
05:34 PM Motioncontrol: another problem the Linuxcnc is motion in position for every axis. in normally cnc when execute a axis position , first the next line execution, cnc wait axis in position fine (data machine for every axis) . if axis not stay in position window the interpreter not excecuted the next line program. in linuxcnc we have a time for wait the axis finisch exact position, this no correct
05:35 PM Motioncontrol: because in some case, a axis for small meccanical program or for no good PID parameter, not complete exact position.
05:36 PM andypugh: I don’t think that is true
05:36 PM Motioncontrol: we not have in linuxcnc a parameter fro define axis in position window
05:38 PM andypugh: LinuxCNC doesn’t wait for feedback. It errors if the feedback is wrong, but it doesn’t wait for feedback before continuing except in the special case of waiting for spiondle speed (when instructed to do so)
05:39 PM Motioncontrol: when linuxcnc executed the next line, not ceck if axis stay in position window. it execute the next line when position command is arrived . but if you have the following value more hight, the axis not is arrived in exact position.
05:43 PM andypugh: You mean if your machine is broken LinuxCNC doesn’t compensate?
05:44 PM andypugh: That is probably true
05:45 PM CaptHindsight: for good reason
05:46 PM andypugh: I think that waiting for an axis that is not following the commanded position would be difficult. How would you conform to accelleration limits on the other axes?
05:48 PM Motioncontrol: andypugh, i work on cnc 30 years old. know cnc and plc Siemens , fanuc, heidenhain ecc. all cnc use position windows, because for move next, the cnc ceck if axis is precise postition. linuxcnc no, not wait axis precise position. in linuxcnc, if axis not have following error , but have error example 1 mm , linuxcnc wait only posion commanded arrived , but the axis have 1 mm the following error and it not stay in correct position
05:48 PM Motioncontrol: fine.
05:48 PM Motioncontrol: i work on cnc 30 years old. know cnc and plc Siemens , fanuc, heidenhain ecc. all cnc use position windows, because for move next, the cnc ceck if axis is precise postition. linuxcnc no, not wait axis precise position. in linuxcnc, if axis not have following error , but have error example 1 mm , linuxcnc wait only posion commanded arrived , but the axis have 1 mm the following error and it not stay in correct position
05:49 PM Motioncontrol: and move for next posiiton first the position precise arrived
05:51 PM rmu: Motioncontrol: you are not talking about G61/G64 ?
05:51 PM andypugh: No, he is talking about waiting for a tary axis to catch up.
05:51 PM Motioncontrol: G61 or G64 not have important with this aspect
05:52 PM andypugh: I can see the argument for the behaviour, but on a path that is blended for speed I think that to do so has to sacrafice position on another axis.
05:53 PM Motioncontrol: CYCLE_TIME = 0.010 - The period, in seconds, at which TASK will run. This parameter affects the polling interval when waiting for motion to complete, when executing a pause instruction, and when accepting a command from a user interface. There is usually no need to change this number.
05:53 PM Motioncontrol: this is in ini file section task
05:54 PM Motioncontrol: this time on normal cnc not existe. every axis have parameter for change axis in precise tollerance
05:55 PM Motioncontrol: normally value 0.01 or 0.005
05:55 PM Motioncontrol: mm
05:57 PM CaptHindsight: Motioncontrol: how do you use that option in a way that benefits you?
05:58 PM Motioncontrol: CaptHindsight, can increase the time
05:58 PM andypugh: Motioncontrol: I have a feeling that CYCLE_TIME doesn’t actually do anything at all.
06:00 PM Motioncontrol: andypugh, i thing it is the time interpreter wait for next command , when position command is arrived
06:00 PM Motioncontrol: i thing it is the time interpreter wait for next command , when position command is arrived
06:01 PM andypugh: I don’t think it is that, there is no pausing in the interpreter layer at all. In fact many programs have interpreed right to the end of the code before the tool even hits the work.
06:03 PM andypugh: http://psha.org.ru/irc/%23emc-devel/2015-11-11.html#19:07:48
06:03 PM andypugh: (Concludes that [TRAJ] CYCLE_TIME is never read.
06:03 PM andypugh: We should remove it from the docs for 2.8.
06:06 PM Motioncontrol: ok linuxcnc not have position window and not have time wait, this is no good.
06:07 PM Motioncontrol: linuxcnc command axis at move and ceck only it not upper the following error window, but not ceck if axis stay in the precise windows.
06:08 PM CaptHindsight: why have two different error limits?
06:10 PM Motioncontrol: not have 2 error limit, only following error limit.
06:12 PM adamj12b: Does anyone have any suggestions on how to store in encoder value into a parameter so that way I can o put it through LOG?
06:13 PM adamj12b: I set up a whole axis as the A axes with a linear encoder so I can map my ball screw, but when I check the numbered perimeter or the named perimeter of the A axis it always return 0.
06:16 PM pcw_mesa: I guess you could capture both the rotary and linear encoder counts simultaneously with halsampler
06:19 PM adamj12b: The strange thing is that it works on the screen the dro reads the current position of the linear encoder I just can't find it as a perimeter if I check #5423 it reads 0. Or if I look at #<_a> it reads
06:20 PM adamj12b: I'm using a 7i77 Mesa setup and this is a full axis now. Originally I just had the encoder section of the axis
06:21 PM adamj12b: It's not a rotary encoder/axis so I thought maybe that's the issue but I programmed it as a linear access
06:44 PM adamj12b2: So if i do a g10 l20 p0 a5, the parameter #<_a> reads 5
06:45 PM CaptHindsight: what is the most accurate way to measure the temp of a water bath from 10C to 100C?
06:46 PM CaptHindsight: RTD and TC?
06:46 PM CaptHindsight: multiple RTD's and averaging?
06:47 PM djdelorie: CaptHindsight: plus, multiple readings on *each* rtd, and average those
06:55 PM andypugh: adamj12b2: You could net halui.axis.a.pos-relative to a G-code analogue input then reead that in with M65(?) before logging.
06:56 PM adamj12b2: andypugh i
06:57 PM adamj12b2: andypugh I was just about to try using the global Hal parameter function #<_hal[component]
07:00 PM andypugh: That won’t work. Those are only updated at cycle-start
07:03 PM adamj12b2: Ok your way it is.
07:04 PM adamj12b2: How would i map the realitive position to a gcode analog input?
07:06 PM adamj12b2: I think you mean m66 for input?
07:07 PM adamj12b2: I think im going in the right direction.
07:12 PM adamj12b2: net map-encoder motion.analog-in-00 <= halui.axis.3.pos-relative
07:12 PM adamj12b2: Then
07:13 PM adamj12b2: M66 E0 L0
07:15 PM adamj12b2: Then parameter 5399 i think... Its labeled "result of m66"
07:46 PM mtpocketscnc1: I signed up in the freecad forum and while I know this is for linuxcnc I've seen alot of guys who seem to be keen on freecad. I want to post a question in the forum but not sure where to as I don't want to ruffle any feathers by putting it in the wrong area of the forum. Anybody post there? I want to ask about if I can convert stl to use somehow in path workbench
07:51 PM djdelorie: wouldn't an stl be a mesh, not a path?
07:51 PM CaptHindsight: mtpocketscnc1: Open discussion should be the safest place if they are moody
07:53 PM CaptHindsight: mtpocketscnc1: or ask politely in #freecad
07:53 PM mtpocketscnc1: okay I will try there. I'm not sure if anyone is there. I just don't want to find out the wrong way lol
07:54 PM CaptHindsight: "Hello, I was born yesterday and am humbly wondering how ..blah blah blah..
07:55 PM mtpocketscnc1: I have tried in #freecad before and don't seem to get much in the way of responses. I'll try it again. I'm guessing with all the hard work in freecad development it must be hard to watch #freecad all the time
07:55 PM CaptHindsight: "Hello, I have suffered miserably as victim of abuse by clowns....
07:55 PM CaptHindsight: sometimes you have to try asking at different times of the day
07:56 PM CaptHindsight: not too often with the same questions
07:56 PM CaptHindsight: like people with welding galvanized or what cnc router to buy
07:57 PM mtpocketscnc1: yep I hear ya. I only ask once and politely wait to see for reply. Maybe I'll go try now. cuz the couple times I tried before it was midday. maybe all busy
07:59 PM CaptHindsight: mtpocketscnc1: from the channel logs it looks like most are in the EU
08:01 PM CaptHindsight: so maybe ~GMT 8:00 - 17:00
08:06 PM mtpocketscnc1: okay. I'm in no rush so if I don't hear back I can try tomorrow. Also googling away to see if I cn figure it out myself. Seems like it has something to do with meshcam but so far eluding me
08:07 PM mtpocketscnc1: I'm by no means the brightest bulb on the tree lol. definately a cnc begginer here :)
08:32 PM Tom_L: CaptHindsight, what cnc dremel router _should_ i buy?
08:44 PM Kevin`: demel? what?
08:47 PM andypugh: Oh. Motioncontrol left
08:47 PM andypugh: Which is annoying because it is 3am and I was thinking about what he said rather than sleeping
08:47 PM Tom_L: andypugh do you know the lines i need in the hal for an ether card?
08:48 PM Tom_L: do i use hm2_eth by itself or does hostmot2 get loaded ahead of it?
08:48 PM andypugh: If he comes back: LinuxCNC comes at that from the other side. If you know that your A axis is slow then set that in the axis/joint limits and LinuxCNC will never ask more of it than it can do.
08:49 PM andypugh: You need loadrt hostmot2 (as usual)
08:49 PM andypugh: then loadrt hm3_eth config=“the usual config string” board_ip=
08:50 PM Tom_L: i'm using the same daughter cards so i can leave that config= line as it is can't i?
08:50 PM Tom_L: in the ini
08:50 PM andypugh: Yes.
08:50 PM Tom_L: just add the loadrt hm2_eth below the hostmot2 line..
08:50 PM andypugh: But you need the board_ip either in the INI or added in the HAL
08:51 PM Tom_L: even if it's the default ip?
08:51 PM andypugh: I think so. It certainly does no harm
08:51 PM Tom_L: i can figure that out i think
08:51 PM Tom_L: so in the ini [HOSTMOT2] section i've got
08:52 PM Tom_L: DRIVER=hm2_7i90 currently
08:52 PM Tom_L: and BOARD=7i90
08:52 PM Tom_L: those will change to the 7i80?
08:52 PM Tom_L: or eliminate them?
08:53 PM Tom_L: i think i would change them to 7i80..
08:54 PM andypugh: Work backwards from the loadrt lines in the HAL
08:54 PM andypugh: See what they look for in the INI
08:54 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/NEW_MILL/
08:55 PM Tom_L: there's the current working config with the 7i90
08:55 PM andypugh: loadrt [HOSTMOT2](DRIVER) config=[HOSTMOT2](CONFIG)
08:55 PM Tom_L: i've got those in it
08:56 PM andypugh: I can’t remember the difference between CONFIG and (CONFIG) in that context.
08:56 PM Tom_L: but since the ethernet has a separate driver i wasn't sure what to do there
08:57 PM andypugh: It’s up to you. Change the INI or change the HA:
08:57 PM andypugh: HAL
08:57 PM Tom_L: ok
08:57 PM andypugh: [SECTION]ITEM just does a text substitution.
08:57 PM Tom_L: yeah, like a constant in c or such
08:58 PM Tom_L: or a #define i should say
08:58 PM andypugh: I nearly always do it all in the HAL, but doing it in the INI can be more portable. (My own configs don’t need to be portable)
08:58 PM andypugh: Anyway, now I really should be asleep
08:58 PM Tom_L: thanks
09:49 PM CaptHindsight: Tom_L: hah!
09:56 PM mtpocketscnc1: CaptHindsight: I just got that with you and Tom_L. Took me a minute though! lol
10:09 PM CaptHindsight: I tend to buy the most expensive one that I can find since time is money and time flies when you are having fun.
10:21 PM mtpocketscnc1: Was just playing with 3d pocket in freecad. locked my computer up. Was taxing it hard though testing out what I can get away with in path workbench
10:22 PM Tom_L: CaptHindsight, have you wired up any ethernet boards?
10:22 PM mtpocketscnc1: CaptHindsight: I thought about router but decided to go with vfd liquid cooled spindle. nice and quiet
10:24 PM Tom_L: in the hal file, i specify config= xxxxxx then board_ip= or such
10:25 PM Tom_L: my question is, if i leave the board_ip= part in and use a different hm2_xx driver like hm2_7i90 will it just ignore the board_ip parameter or throw an error?
10:25 PM Tom_L: i could go out and test it but it's late, dark, and i'm tired..
10:26 PM CaptHindsight: Tom_L: I have some 7i90's but I did not configure them
10:26 PM Tom_L: i'm modding my 7i90 config for the 7i80
10:26 PM Tom_L: practically identical except the interface
10:26 PM Tom_L: this is just to test
10:27 PM Tom_L: i'm just wondering if unused parameters in the hal file get ignored or not
10:27 PM CaptHindsight: oh we have 7i80's
10:28 PM CaptHindsight: I can't remember part numbers anymore :)
10:28 PM Tom_L: both are 3 headers
10:28 PM Tom_L: 50? pin
10:29 PM CaptHindsight: and 7i92
10:29 PM Tom_L: the bit file is practically identical too
10:29 PM Tom_L: 7i92 is 34 io
10:29 PM Tom_L: 2 x 17
10:29 PM CaptHindsight: if you say so :)
10:29 PM Tom_L: i just programmed one
10:30 PM Tom_L: i added the dpll stuff to the bit file which the 7i90 didn't have but it will work for either one
10:31 PM CaptHindsight: I might have to try that on one board I have, servo latency is >200K
10:31 PM CaptHindsight: jitter
10:32 PM Tom_L: i think i put it first in the list but i'm not sure it matters
10:32 PM CaptHindsight: not sure what the rule is but sometimes HAL order matters
10:33 PM Tom_L: i'm referring to the bit file or .vhd
10:35 PM CaptHindsight: order should not matter but connections will
10:35 PM Tom_itx: (HM2DPLLTag, x"00", ClockLowTag, x"01", HM2DPLLBaseRateAddr&PadT, HM2DPLLNumRegs, x"00", HM2DPLLMPBitMask),
10:35 PM Tom_L: is the first element in the array
10:35 PM Tom_L: it has no pins associated with it
10:36 PM Tom_L: but you gotta remove a NullTag if you add it
10:37 PM Tom_L: 32 entries iirc

10:47 PM Tom_L: is that the new backup generator of the future?
10:47 PM CaptHindsight: yeah, but for space and not my space at home
10:48 PM CaptHindsight: sure, as soon as capitalism ends :)
10:51 PM CaptHindsight: hazzy-dev: how does the floorpan project look?
10:53 PM hazzy-dev: CaptHindsight: I have not had time to work on the floors, but I did get the passenger side door patched up

10:55 PM hazzy-dev: Oops!
10:57 PM mtpocketscnc1: $8500 dollar fine seems a bit low to me considering what they lost!
10:57 PM hazzy-dev: This guy is doing some pretty neat stuff on small fusors, too bad he got radiation poisoning
10:57 PM hazzy-dev: http://www.fusor.net/doug-coulters-solar-power-star-in-a-jar/
10:59 PM hazzy-dev: mtpocketscnc1: It is really not that big of a deal, there are a lot of other radioactive materials that are more hazardous, but readily available
11:00 PM hazzy-dev: plutonium is one of the safer things to handle, and you need a lot of it to do anything real with it
11:06 PM hazzy-dev: A guy down at tech made a pretty nice fusor not too long ago: http://www.rtftechnologies.org/physics/fusor-mark3-upgrades1.htm
11:06 PM mtpocketscnc1: I see your point. I guess I just get concerned with the amount of radiation introduced to the planet
11:07 PM nallar is now known as Ross
11:08 PM hazzy-dev: mtpocketscnc1: It is already on the planet! I have some highly radiative uranium from Canada, it is over 15% pure and was basically just dug up, not refined or anything :)
11:08 PM hazzy-dev: The Canadians use it directly in their reactors with not enrichment!
11:08 PM CaptHindsight: hazzy-dev: whats the latest on molten salt or thorium reactors?
11:10 PM hazzy-dev: CaptHindsight: I don't think anybody is making much progress, mostly still 70s tech last I heard, but I don't follow it much these days
11:11 PM hazzy-dev: All I really know about it old PWRs :)
11:12 PM mtpocketscnc1: This guys outta here. My youngest finally went to sleep and now it's dad's turn. Have a goodnight all :)

11:17 PM hazzy-dev: Interesting, I would love to see SMRs popping up (or down), it seems like standardization is the only way to make nuclear power plants cheap enough to compete with gas
11:17 PM CaptHindsight: sorry to keep you up :)
11:18 PM CaptHindsight: I was just reading the comments in that article
11:18 PM hazzy-dev: Oh no, I was saying night to tmtpocketscnc1!
11:22 PM hazzy-dev: the loss of Westinghouse nuclear has been a big blow on the construction of the two new NPPs here, they were originally supposed to be online pretty soon now, but know they keeping pushing it back
