01:30 AM archivist: CaptHindsight, homebrew CMM will not be affected
02:02 AM LeelooMinai: I had no idea that bubble levels could be so precise... https://www.youtube.com/watch?v=zx2sjNvNlM0
02:04 AM archivist: dont break a bubble, it is costly to replace
02:05 AM archivist: cost me £85 when I broke one
02:06 AM LeelooMinai: Heh, watched only half of that video - will watch the rest later, since I go to sleep now, but just checked and they are not cheap at all.
02:21 AM Deejay: moin
04:50 AM XXCoder: boo
04:51 AM XXCoder: LeelooMinai: I'm pretty sure the strigher the tube the more accurate it is
04:51 AM XXCoder: the longer it has to be too I bet. though cant have zero bend tube, that'd be impossible
04:57 AM pink_vampire: hiiii
04:58 AM XXCoder: hey hemophile
04:58 AM XXCoder: hows things
05:09 AM pink_vampire: I'm trying to make the tool path for a new part
05:14 AM jthornton: morning
05:15 AM Tom_itx: sure did alot of growling for no rain last night
05:16 AM XXCoder: pink yeah? manually or using some cam like mastercam?
05:16 AM XXCoder: hey jthornton
05:17 AM jthornton: I slept like a log last night
05:17 AM XXCoder: jt remember the broken corsel on machine? maintance guy said just ignore it and keep running. he already ordered new part and job is very late anyway
05:17 AM jthornton: yea I remember it
05:17 AM XXCoder: its annoying to see it grind in and out
05:18 AM jthornton: hmm looks like we may get some rain today
05:54 AM phipli: morning
05:55 AM jthornton: morning
05:55 AM phipli: how goes?
05:56 AM XXCoder: hey
05:56 AM phipli: morning XXCoder
05:56 AM XXCoder: whats up
05:57 AM phipli: Sky/Stars
05:59 AM jthornton: hows the lathe coming along?
05:59 AM phipli: not touched it yet today
05:59 AM phipli: little late getting up
05:59 AM XXCoder: down long enough is also sky then stars just like up lol
06:00 AM phipli: didn't get to sleep until late... and then the missus snored until half 4 in the morning...
06:00 AM phipli: XXCoder: on average, it is void
06:00 AM XXCoder: phipli: solids are also essentally over 99% empty space
06:00 AM * phipli whimpers at the magnitude of nothingness
06:02 AM phipli: jthornton: learnt how to do html forms last night though (I really don't html, always stuck to desktop apps)
06:02 AM phipli: so can add a settings page to the chickendoor
06:03 AM XXCoder: fancy
06:03 AM jthornton: cool, I've done a bunch of html by hand and have a make file to convert asciidoc text files to html
06:03 AM jthornton: I love it when a library has something like this in the description "There are many convenience macros in TimeLib.h for time constants and conversion of time units." but no listing of them
06:04 AM phipli: heh
06:04 AM archivist_herron: that would the file itself :)
06:05 AM phipli: yes, after reading the documentation on a file reading library I was reading data in byte at a time from a file...
06:05 AM phipli: then found someone elses example that had "readUntilChar"
06:05 AM phipli: just...
06:05 AM phipli: just...
06:05 AM phipli: damnit
06:05 AM phipli: it wasn't listed in the documentation!
06:16 AM pink_vampire: I have an issue with linux cnc
06:16 AM XXCoder: yeah?
06:18 AM pink_vampire: I took 1280X1024 screen and 1600X1200, and they connect with Y cable to the linux cnc vga output. but the screens flicker all the time
06:19 AM phipli: have you set the refresh rate to above 60hz?
06:19 AM phipli: oh, wait, are they CRT or LCD
06:19 AM pink_vampire: I need to disconnect the 1600X1200, then reboot the computer, and after the login to connect it back
06:19 AM pink_vampire: LCD
06:19 AM phipli: for some reason I just timewarped 20 years and was thinking CRT
06:20 AM phipli: have you booted in another OS?
06:20 AM phipli: to test?
06:20 AM pink_vampire: no
06:21 AM pink_vampire: is there a way to set the resolution in advanced to 1280X1204
06:21 AM XXCoder: lcd flicerking is weird
06:22 AM phipli: urgh. xorg.conf
06:22 AM phipli: chances of breaking something : 50%
06:34 AM pink_vampire: what do you mean?
06:35 AM XXCoder: dont mess with xorg.conf
06:35 AM XXCoder: I think theres utilities to edit with parts of it. never use that directly
06:48 AM phipli: basically most times you touch it, you spend two days without a GUI
06:49 AM phipli: so yes, what XXCoder said
06:50 AM jthornton: no firewood splitting today it's starting to rain
06:50 AM phipli: XXCoder: I had a second hand Sony Vaio P series with closed source graphics chip
06:50 AM phipli: gave me no end of grief
06:51 AM phipli: but taught me a lot of command line
06:51 AM phipli: because the GUI hardly ever worked
06:51 AM XXCoder: fun
06:51 AM phipli: shame it didn't work better - I liked the high res tiny screen
06:52 AM phipli: jthornton: I've split my program into several files because it was getting unreadable
06:56 AM jthornton: so you just #import the files?
06:57 AM phipli: you can do that, but there is a built in function to let you split your project
06:58 AM phipli: if you look at an IDE window, there is a downward pointing arrow under the magnifying glass (for serial monitor)
06:58 AM phipli: click on that
06:58 AM phipli: there is a "New Tab" option
06:59 AM phipli: if you just name the file without an extension, the compiler automatically concatenates any code from the extra tabs into the same file before pre-processing and compiling
06:59 AM phipli: so it is like having all the code in one file...
06:59 AM phipli: but you get to organise your thoughts a bit better!
07:01 AM jthornton: ah I see that now cool
07:02 AM phipli: useful for big programs. basically the same as include
07:06 AM phipli: did it crash your machine? :)
07:07 AM jthornton: no, I was messing with the computer date to test some code
07:12 AM jthornton: I did find a compact algorithm that returns the day of the week from a date
07:25 AM jthornton: phipli: making some progress http://paste.ubuntu.com/24864121/
07:25 AM jthornton: took your month example and added the dow code I found on the web and now I have enough to determine if it is dst or not
07:26 AM phipli: the date format is always the same length?
07:26 AM phipli: includes leading zeros?
07:27 AM jthornton: yes, that is what I was testing a space I think
07:27 AM jthornton: changed date to 6/1 to test
07:27 AM phipli: good good
07:27 AM jthornton: then changed back to 6/15 but had to reboot to get it sorted out
07:27 AM phipli: and 10/10? :)
07:27 AM jthornton: gotta test that
07:28 AM phipli: your code always looks neater than mine
07:28 AM phipli: you do you write with so little indentation?!
07:29 AM jthornton: yes I like 2 spaces for tabs so the code does not run off the right side
07:31 AM jthornton: time to start my day see you in the shop
07:31 AM * phipli waves
07:50 AM * JT-Shop waves back
07:55 AM phipli: just got a thrust bearing in the post
07:55 AM phipli: will make a rivnut tool for bigger rivnuts sometime today
07:55 AM JT-Shop: cool
07:56 AM phipli: heh - nextdoor's kit is smashing things again
07:56 AM phipli: about 2 years old
07:56 AM phipli: constantly pounding things into the dust
07:57 AM phipli: I know the kids name better than the rest of them because they spend their whole time shouting "No! Jason! Stop that!"
07:57 AM phipli: You should let him loose on your log pile
07:58 AM JT-Shop: lol
07:59 AM phipli: Phew. Finally worked out what was causing my module to fail to connect to the wifi sometimes
08:00 AM phipli: it was automatically connecting with the previous settings before I'd had a chance to, then, it wouldn't "connect" because it already was
08:00 AM phipli: I had to guess that it was the issue and include the command "am I already connected?"
08:01 AM Spida: phipli: Neighbours cat once thought its name was "No" for a similar reason :-)
08:02 AM phipli: heh
08:03 AM phipli: I can tell you, with absolute certainty, that the child does not respond to the name "No". I can also tell you that it does not respond to the name "Jason"
10:21 AM JT-Shop: phipli: https://www.amazon.com/Elegoo-ATmega328P-ATMEGA16U2-Compatible-Arduino/dp/B01EWOE0UU/
10:25 AM phipli: JT-Shop: https://www.banggood.com/UNO-R3-ATmega328P-Development-Board-For-Arduino-No-Cable-p-964163.html?rmmds=search
10:25 AM phipli: :)
10:25 AM phipli: you can go lower with ali-express... but they don't take paypal
10:30 AM JT-Shop: I don't use paypal to buy things messes up my accounting
10:36 AM * JT-Shop squares up a 5" cube of oak on the mill
10:59 AM phipli: JT-Shop: Dropped you an email with the latest version of my near-sentient door opening program
11:05 AM pink_vampire: hii
11:07 AM pink_vampire: how to i calculate depth of cut?
11:12 AM Deejay: throw the dice!
11:12 AM Deejay: ah, wait, you wrote calculate... hmm
11:13 AM Deejay: its that with all the numbers, right? ;)
11:13 AM * Deejay did woodworking today
11:13 AM Deejay: <3 wood
11:15 AM JT-Shop: phipli: got it :)
11:15 AM * JT-Shop notices that machining green red oak smells nice
11:18 AM phipli: :)
11:18 AM phipli: you'll have to get yourself some fruit wood
11:34 AM SpeedEvil: https://www.youtube.com/watch?v=uPwU06Byc8s how to grind a taper.
11:35 AM roycroft: many are the ways one can grind a taper
11:35 AM roycroft: that is not one of them
11:39 AM jdh: red oak is bad for lungs
11:42 AM roycroft: yes, a lot of woods are
11:43 AM roycroft: i love the smell of cedar, but i have to wear a dust mask when i do any work with it at all
11:45 AM CaptHindsight: I enjoy ethanol and water that has soaked in oak barrels
11:46 AM CaptHindsight: wood is good
11:51 AM Cromaglious_: charred oak is better... the sugars in the wood turn into a caramel and add flavor to the water... I love leaf flavored water.
11:54 AM CaptHindsight: some are great when charred with peat
11:57 AM nos__: Anybody done the research on getting a hard and shiny surface on aluminum? 7075, perhaps?
11:57 AM nos__ is now known as nos
11:58 AM Cromaglious_: epoxy Gorilla glass to it?
11:58 AM nos: It'd be a complex shape. I want to make parts for an AR-15 space gun.
11:59 AM nos: Shiny and useless.
11:59 AM sync: rotary tumbling will increase surface hardness to a degree
11:59 AM Cromaglious_: anodize or powder coat (both are additive so watch your tolerances)
11:59 AM sync: but if you predict wear hard anodizing is the only way to go
12:00 PM Cromaglious_: I'm using rattle can on my AR-15 lower
12:00 PM nos: What I just saw of hard anodizing was that it makes a rather dark surface.
12:00 PM Cromaglious_: It'll have a curing session in the oven
12:01 PM nos: I was thinking, maybe I could ball peen the surface, then maybe electropolish...
12:01 PM sync: sure, but that will only harden the surface so much
12:01 PM CaptHindsight: how shiny? like bright anodize?
12:02 PM CaptHindsight: it won't be hard without anodize
12:02 PM nos: The shinier the better, but up to a point. It's cosmetic so it doesn't have to be pefrect.
12:02 PM CaptHindsight: and how deep do you want the hardness?
12:02 PM roycroft: anodising does not have to be dark
12:03 PM CaptHindsight: DIY or are you looking for someone to treat it?
12:03 PM sync: aha, a non perfect cosmetic surface
12:03 PM sync: that is kind of an oxymoron
12:04 PM nos: It would have to hold up to being taken to a shooting range and shown off.
12:04 PM CaptHindsight: bright dip and then hard anodize
12:05 PM CaptHindsight: bright dip is an electropolish
12:05 PM nos: hmm!
12:05 PM CaptHindsight: once it's smooth it may be hard anodized
12:07 PM nos: Thanks, I'll look into this! :)
12:08 PM CaptHindsight: but...
12:08 PM CaptHindsight: you can still scratch it
12:08 PM CaptHindsight: and if it's gloss the scratch will stand out more
12:09 PM CaptHindsight: so it will look great new
12:09 PM nos: Yeah... It's just alu underneath. That's why I was thinking about ball peening, to get the oxide layer to go deper.
12:09 PM CaptHindsight: but after a few drops it won't
12:10 PM CaptHindsight: the oxide won't go any deeper than hard anodize
12:10 PM nos: aah..
12:10 PM CaptHindsight: peening won't help
12:10 PM CaptHindsight: few thou at most
12:10 PM nos: good, then I won't have to spent time/money on it...
12:11 PM CaptHindsight: 7xxx series isn't great for light colors
12:11 PM nos: It seems to be a little reddish.
12:11 PM CaptHindsight: are you going to go with a shade of black?
12:12 PM nos: If mirror blank is a shade of black yeah
12:12 PM nos: It's supposed to look like something out of an 80s sci-fi movie.
12:12 PM CaptHindsight: https://www.pioneermetal.com/anodizing-finishes has a good comparison
12:13 PM nos: I'm planning on making an ammo counter too.
12:13 PM nos: https://www.youtube.com/watch?v=ETC1TdYOIwE
12:13 PM nos: similar to this
12:14 PM CaptHindsight: unless you are going to invest in DIY then you just need to see what the anodizers in your area offer
12:15 PM nos: I have the electronics skill to make it. The only gotcha is the round in the chamber, which would need a stainless barrel, magnetic sensor, and steel casing.
12:15 PM nos: Well there is someone who offers diamond-like carbon...
12:15 PM nos: PVD.
12:15 PM nos: Not too expensive, I hear.
12:16 PM CaptHindsight: if you want to pay for that
12:16 PM CaptHindsight: but it's still thin and brittle
12:16 PM sync: dlc is no too expensive
12:16 PM sync: but it is black
12:16 PM CaptHindsight: think of it like an egg shell
12:17 PM CaptHindsight: another option is using titanium or tool steel, then aluminum plating, then anodize
12:17 PM nos: hmm
12:18 PM CaptHindsight: I have some black anodized cold roll
12:18 PM CaptHindsight: cold roll thats been aluminum plated and then anodized
12:18 PM nos: Problem is productivity. I'd like to make 1000 of 'em and sell them. Alu cuts cheap and fast and I want to rent machine time. I can get time for 50-80 eur/h, plus 1500 eur/annum insurance.
12:19 PM nos: My teacher said he can make 400 eur per hour, doing his own thing.
12:19 PM CaptHindsight: http://www.alumiplate.com/
12:20 PM CaptHindsight: all depends on what you want to make and for how much
12:21 PM sync: I would probably just rotary tumble them
12:21 PM CaptHindsight: what part is this?
12:21 PM sync: that will polish them good enough
12:22 PM nos: I was thinking about making a stock first. I see them go for around $120 a piece, and I think I can compete with that.
12:22 PM CaptHindsight: doodads that attach to ar15's
12:22 PM nos: exactly
12:22 PM CaptHindsight: urethane composites might be another option
12:24 PM nos: I'm not looking to make something super-light, or super-high perf. It would be light enough, and shiny, for people who like shiny things. Lots of revolvers are shiny.
12:25 PM JT-Shop: well crap now I'm back to permission problems with the BP mill... can't copy a file to it anymore
12:26 PM CaptHindsight: https://www.maxprotactical.com/TN_Arms_Ghost_Gun_AR_15_Stripped_Lower_Receiver_p/tnarms-ar15-slr-gg.htm
12:27 PM CaptHindsight: got me thinking about injection molding the whole thing
12:28 PM CaptHindsight: then again i was just at Amerimold yesterday :)
12:28 PM nos: That is really inexpensive for such an obscure part...
12:29 PM nos: Now InRange TV's WWSD series makes more sense.
12:29 PM CaptHindsight: that one is made from pretty poor plastic
12:29 PM CaptHindsight: but reinforced nylon or ABS is a few cents more
12:30 PM nos: I hear ABS isn't all that great as a plastic.
12:30 PM CaptHindsight: depends on the blend
12:30 PM nos: Now polycarbonate...
12:30 PM roycroft: abs is usually full of shite :)
12:31 PM CaptHindsight: polycarbonite is also inexpensive
12:31 PM CaptHindsight: depends on the blend, when you buy pellets they are rarely neat
12:32 PM CaptHindsight: who knows what crap they use for ABS filament for CNC glue guns
12:33 PM IchGucksLive: hi
12:33 PM nos: o/
12:33 PM IchGucksLive: Loetmichel: bad weathere hedding your way
12:33 PM nos: I'll melt CDs onto a wooden stock!
12:34 PM nos: Shiny aluminium coatign protected with with polyc!
12:35 PM roycroft: i always thought that making things out of swarf would be fun
12:36 PM roycroft: if you make nice chips that are little "6" shaped, and get some nice dark straw/blue/purple color on them, embedding them in plastic in a mold could make some nice decorative pieces
12:36 PM roycroft: and let you recycle your swarf
12:37 PM nos: hmm
12:39 PM nos: The chips would have a decent surface roughness for the polymer to stick to, and work nicey as a tough, hardened filler.
12:39 PM nos: That might just work.
12:39 PM roycroft: and it would be shiny and colorful
12:40 PM nos: Just gather up some old CDs and melt em. :)
12:40 PM roycroft: and it would encourage you to make good chips
12:40 PM nos: Polycarbonate has a rather low viscosity when molten.
12:42 PM CaptHindsight: think of ABS, Nylon, PC as having a range of qualities rather than something exact
12:43 PM CaptHindsight: they all come with a variety of properties since they add other materials to change their properties
12:53 PM kyle____: I created a nichrome heating element last night
12:53 PM nos: Been thinking about making an injection molding auger out of a big rock/concrete drill.
12:54 PM kyle____: I just wrapped 25 feet of 22awg wire around a dowel chucked in a cordless drill, fun stuff
12:54 PM kyle____: about 40 ohms
12:54 PM nos: what's it for?
12:54 PM nos: also, toaster ovens!
12:55 PM kyle____: going to embed it in a plaster of paris/sand hunk of junk and melt some zamak
12:56 PM kyle____: still wondering how to power it
12:57 PM archivist: cooker element also, straight mains driven
12:57 PM kyle____: are they? hm
12:57 PM kyle____: I guess I should peek inside this broken toaster oven I have
12:57 PM kyle____: lots to learn
12:58 PM kyle____: I have a ton of MOSFETs too so I could probably make some PWM switching power supply
12:58 PM archivist: my bluing kiln has one, then ally heat spreader then tray of sand
12:58 PM kyle____: yeah
12:58 PM kyle____: I was hoping to power it with DC so my tiny programmer brain could comprehend what's going on
12:58 PM archivist: I use an old honeywell temperature controller with a thermocouple
12:59 PM kyle____: huh
12:59 PM archivist: you can get cheap controllers of ebay
12:59 PM kyle____: I'll check into that, thank you
12:59 PM kyle____: it's tempting to do it myself with one of my spare STM32 boards but I should try to not overcomplicate this
01:00 PM archivist: they know hou to ramp up and pwm, its all done
01:00 PM kyle____: sounds good
01:00 PM kyle____: do you know if 22awg is too small?
01:00 PM archivist: http://www.collection.archivist.info/searchv13.php?searchstr=bluing+kiln
01:01 PM kyle____: ah, nice
01:01 PM kyle____: what kind of input power is it drawing?
01:02 PM kyle____: and what temperatures do you run at?
01:02 PM kyle____: (sorry for the avalanche of questions)
01:02 PM archivist: has a great big relay, too lazy so far to put in the SSR I got
01:02 PM archivist: that has a set point of 325 for blue on mild steel
01:03 PM archivist: 315
01:03 PM kyle____: hm, okay, not too far off from what I want
01:03 PM archivist: sorry 305 for dark blue
01:04 PM archivist: 315 is light blue
01:04 PM kyle____: I'm aiming for around 390 C for melting zamak, it seems
01:04 PM kyle____: I just realized I live 30 minutes from rotometals so I'm excited to try zamak casting
01:05 PM archivist: Zinc you mean
01:05 PM kyle____: yeah, zinc-aluminum alloy
01:05 PM archivist: monkey metal
01:05 PM kyle____: it seems there are strong opinions of it all over the web :P
01:06 PM archivist: just been repairing a lock which failed by fracture
01:06 PM kyle____: that doesn't sound like a very good lock
01:07 PM archivist: cheap to manufacture good, durability poor
01:09 PM IchGucksLive: kyle___ why 3 underscores if you are bussy
01:09 PM sync: why not
01:09 PM IchGucksLive: isent it a indicator for not around
01:10 PM kyle____: eh, if it is, sorry
01:10 PM kyle____: my irc client has 4 backup names and each one is just another _ :P
01:10 PM IchGucksLive: NP just asking
01:11 PM IchGucksLive: ok im off i had a hard day harvesting greens for bioenergie
01:11 PM kyle____: have a good one!
01:11 PM IchGucksLive: 3days and 100acers to go
01:12 PM JT-Shop: cutting the cake tin holder maxes out my Y axis almost
01:13 PM archivist: use a rotary there is no limit to arcs then :)
01:19 PM kyle____: heh, so on an unrelated note, I have an HTC vive VR headset at my desk at work
01:19 PM kyle____: and the "lighthouses" it uses for tracking have a spinning mirror and a laser that pulses, so that you get a regular sweep pattern
01:19 PM kyle____: they just run constantly and aren't communicating with anything
01:20 PM kyle____: but since it's an office, we just plugged them in and left them, and they have about 8,000 hours on them now
01:20 PM kyle____: sounds like one of the bearings is failing
01:20 PM JT-Shop: I just need one of those round wooden things with the word tuit printed on it and I'll get my rotary up and running
01:21 PM Todd_Z: but don't you need the rotary to make those
01:26 PM JT-Shop: if you don't have a lathe
02:07 PM CaptHindsight: anyone ever deal with this vendor? http://www.southwesternindustries.com/
02:07 PM CaptHindsight: they bragged about their conversational input vs only g-code
02:08 PM CaptHindsight: and their $30k Bridgeport retrofits
02:09 PM nos: You can get a decent lathe for that money...
02:12 PM CaptHindsight: tried to tell me how Prototrak was better than LCNC for me
02:14 PM CaptHindsight: I poked a bit of fun at their greediness and lack of insight into LCNC and walked on
02:20 PM nos: That reminds me, I disocevered the hard way that Fanuc simulation doesn't account for rapids. At 1% rapid speed, fortunately, so I just lost a part which had already been subject to an endmill wandering out of its collet.
02:21 PM nos: The 6-flute bit we use for finishing seems just happy to take on roughing jobs too.
02:26 PM CaptHindsight: why beat up a nice too on roughing?
02:26 PM CaptHindsight: too/tool
02:41 PM nos: I didn't intend to. I thought the sim was telling me I'm good to go.
02:42 PM nos: I'll upload some pics
02:43 PM nos: http://imgur.com/a/664Kh
02:43 PM _methods: oops
02:45 PM nos: Should have been X0 instead of Y22.5
02:46 PM LeelooMinai: Looks like mill decided "Ok, I need to get out of here":)
02:46 PM nos: lol
02:47 PM LeelooMinai: That's a steel part, right?
02:47 PM nos: It felt trapped
02:47 PM nos: ya
02:47 PM nos: low carb
02:47 PM LeelooMinai: Hmm, nice
02:48 PM nos: G-code school assignment. I'm training to be a Real Machinist (tm).
02:49 PM LeelooMinai: I would think that for school they tell you to use an easier material.
02:50 PM nos: It's cheap.
02:50 PM LeelooMinai: Well, the tooling/machine is not though.
02:50 PM nos: They have a 250 000 eur Mazak 7 axis lathe. :b
02:50 PM LeelooMinai: A, ok:)
02:51 PM nos: I asked how they got the money;
02:51 PM nos: "Drugs"
02:51 PM LeelooMinai: Well, still, they are brave to let students use it...
02:52 PM nos: This is a institute around 100 years old in the capitol of the country, so they probably have the dough.
02:52 PM LeelooMinai: I hope it has a good crash-detection system:)
02:52 PM nos: Sure. It's called swearing.
02:53 PM LeelooMinai: "You crash the ting, you are out of this school, now go ahead - you are still 100% sure your code is ok?"
02:54 PM nos: I see crash-marks on parts in the art bin pretty often.
02:55 PM nos: The machines are in pretty good condition though. 'cept for an old Takasawi lathe which out of commission.
02:55 PM LeelooMinai: I once wondered if one could make some sensible system for detecting crashes - I don't know, maybe based on unexpeced/high forces on the spindle and ballscrews or something.
02:56 PM nos: My little 500W Chinese mini-lathe has that.
02:56 PM LeelooMinai: You can set some force limits?
02:56 PM nos: I haven't used it much, but it got me to decide I wanted to do more, and work on bigger machines.
02:57 PM nos: No, it just has some defaults.
02:57 PM nos: I assume it detects a surge in power. It has a DC motor so the electronics to do that is probably simpler.
02:58 PM * LeelooMinai is looking for some good free mind mapping software (in case someone uses some and has a tip/opinion)
02:59 PM nos: there was a link going around for thatjust last week... let me see
02:59 PM nos: https://github.com/nikitavoloboev/learn-anything
02:59 PM LeelooMinai: I saw google has comething nice, but it's online only
03:00 PM nos: hmmm...there used to be code there
03:01 PM nos: The site is up though.
03:03 PM LeelooMinai: I wish by 2017 3D would be more of a thing - one could make some interesting interfaces into apps like that in 3D space.
03:04 PM LeelooMinai: Also, CAD/CAM - fail:/ Real 3D system for those would be great.
03:04 PM nos: I'm really looking forward to what VR can do for UI design.
03:05 PM LeelooMinai: Probably the only hope is gaming - if something takes of there, it can be usable for CAD, etc.
03:05 PM nos: There are a lot of UI elements which one could simply keep in one's imagination, once one is trained for them, and have the UI as something a smartphone maintains.
03:06 PM LeelooMinai: What do you mean "in imagination":) If you only imagine them, then there's no UI:p
03:06 PM LeelooMinai: Or you mean that they take symbolic form that is specific to you?
03:07 PM nos: Say you have a VR UI which you interact with by waving your arms around and pointing at things; you can still do that when you don't have the headset on.
03:08 PM nos: e.g. say 'lights' and raise and lower your palm to interact with room light dimming.
03:08 PM LeelooMinai: Well, the headset, I don't know - that's probably the culprit in itself. I guess a breaktrhough would be a monitor that is 3D in itself somehow and does not require any gear on the user.
03:09 PM * nos already has glasses
03:09 PM nos: Maybe a projecto which sines lasers against the glasses.
03:09 PM nos: ~shines
03:10 PM sync: shutter glasses or polarizer glasses would be ok tho, but there is 0 innovation in that
03:10 PM sync: cad software could export into 3d space in the 90s
03:10 PM sync: and companies had vr rooms to look at 3d integration
03:10 PM nos: I have a super-complicated idea for making R2-D2 like holograms.
03:10 PM nos: Based on ultrasonics and water mist.
03:11 PM LeelooMinai: I don't know... People do not like waring things on their head just to look at something. I would think something that can track your eyeballs remotelly and play with the screen accordingly would have much more chance to be adopted universally.
03:12 PM nos: There is something like that.
03:13 PM nos: ...Track IR?
03:13 PM nos: ah yeah
03:13 PM nos: Support is a bit spotty, and it is games only.
03:13 PM LeelooMinai: Hmm, but that may be for input, no?\
03:14 PM LeelooMinai: Right, seems that it's more like an input device.
03:15 PM nos: Yeah, you have to wear something on your head still.
03:15 PM LeelooMinai: lol, I guess one could use it in CAD too, but it would be pretty bizarre seeing someone using head to rotate the model, etc.
03:16 PM nos: There was somone who did make their driver accept input from a webcam which did headtracking in software... but that's an abandoned project.
03:16 PM LeelooMinai: And repetetive neck injury here it comes
03:16 PM nos: I hope to get in shape again with VR games...
03:16 PM LeelooMinai: "My friend tried to do a barrel roll and now he needs a collar"
03:17 PM LeelooMinai: No games for me any more probably. But, if one day CAD in 3D becomes viable, I will try it maybe.
03:18 PM LeelooMinai: Hmm, what was I doing...
03:19 PM LeelooMinai: O, right, ironically I was searching for mind mapping software, so I don't forget what is my main focus:/
03:19 PM nos: lol
03:20 PM DaViruz: i doubt you will get a neck injury from looking around
03:20 PM DaViruz: the neck is kind of meant to do that
03:20 PM nos: Yeah, it's sitting staring at a glowing recangle which is unnatural.
03:21 PM LeelooMinai: Well, I have 3 monitors and until I made my position/chair great again and got proper head support, I had muscle problems in the neck quite frequently. Now they are gone.
03:24 PM DaViruz: make chairs great again
03:24 PM nos: There is one company which was able to make VR goggles great again so that your eyes need to focus on stuff.
03:25 PM LeelooMinai: I heard names like Oculus mostly, but never anything that really caught my attention.
03:26 PM DaViruz: current vr is pretty cool. but it has a looong way to go still
03:26 PM nos: https://www.youtube.com/watch?v=gl2SSDrQvps
03:28 PM nos: It's mostly a guy explaining how their stuff works,
03:28 PM LeelooMinai: Retinal imaging - a bit disturbing... Imagine a bug that imprints something on your retinas permanently, like an Apple logo:)
03:28 PM nos: lol
03:31 PM CaptHindsight: why are people in their 50's/60's walking out on their jobs with nothing lined up? Is this just anomaly around me or is this common lately?
03:32 PM LeelooMinai: Seems they are after augmented reality - imposing stuff on normal view. Kind of like those velding helmets, that would colour the image by heat, give you stats about the welder pwoer, etc.
03:32 PM nos: CaptHindsight: Didn't know about that. It sounds really misguided in today's climate, or really arrogant.
03:34 PM cradek: or their situation is intolerable
03:34 PM nos: Hope it's not that bad...
03:40 PM kyle____: ah I missed the VR talk
03:41 PM nos: And since we're not a bunch of nerds, it will never happen again.
03:41 PM kyle____: :(
03:42 PM nos: Until someone mentions something cool.
03:43 PM LeelooMinai: Hmm, that Coggle thing from Google seems to be simple/ok
03:43 PM LeelooMinai: And visually pleasing - probably will just bugger it and use that for now.
03:45 PM kyle____: I've considered building my own motion-tracked pen that uses the same tech oculus uses for tracking their controllers
03:46 PM kyle____: since it's crazy cheap to do so; just need IR LEDs and an IR-filtered camera
03:46 PM kyle____: for CAD or something
03:46 PM kyle____: but you'd need AR goggles for it to really be useful
03:46 PM kyle____: then you could sketch on your desk and view the model right in front of you
03:47 PM nos: We can use mice just fine although the cursor isn't in the same spot as the device.
03:47 PM nos: Same with wacom tablets.
03:49 PM * JT-Shop wonders what channel this is...
03:50 PM CaptHindsight: it might be part of getting people to quit vs laying them off or firing them without due cause
03:52 PM nos: lol
03:53 PM nos: Eventually it'll be entire companies entirely made up of their HR dept.
03:58 PM XXCoder: 120% of employees is jr ej
03:59 PM XXCoder: *hr eh
04:05 PM DaViruz: kyle____: we have sort of a XXL version of that pen at work
04:05 PM roycroft: i have a calculator whose brushed aluminuim bezel has some minor scratches
04:05 PM kyle____: tell me more, DaViruz
04:05 PM DaViruz: https://www.cmmxyz.com/assets/images/hq-equipment/laser-trackers/B-Probe.jpg
04:05 PM DaViruz: leica b-probe
04:05 PM kyle____: ah, cool
04:05 PM roycroft: www.roycroft.us/11c.jpeg
04:05 PM kyle____: I bet that wasn't cheap
04:05 PM DaViruz: it is not
04:06 PM DaViruz: thou much cheaper than the t-probe
04:06 PM XXCoder: depends on defintion of cheap lol
04:06 PM roycroft: any ideas on how to restore that brushed appearance and get ris of the scratches?
04:06 PM kyle____: the oculus rift tracked controllers are $50 each iirc
04:06 PM roycroft: i don't expect it to look brand new again
04:06 PM kyle____: but they are much less precise than you need for that
04:06 PM roycroft: but i'd like it to look a bit nicer than that
04:06 PM XXCoder: roycroft: wild guess, re-brush it? dimmp ;p;
04:06 PM XXCoder: *dunno lol
04:06 PM kyle____: maybe a brush wheel!
04:06 PM roycroft: should i try to remove the bezel from the calculator and touch it on some wet and dry?
04:06 PM roycroft: i want an even, brushed look
04:07 PM roycroft: as it came from the factory
04:07 PM roycroft: that hp logo is problematic, because it sticks up above the bezel
04:07 PM DaViruz: i have attempted such finishes at times, but never succeeded
04:07 PM roycroft: it's worth restoring, imo
04:07 PM DaViruz: though i haven't really given it a serious attempt to be honest
04:07 PM roycroft: it's a great, classic calculator
04:07 PM roycroft: from 1981 :)
04:08 PM XXCoder: roy thats usually a sticker
04:08 PM roycroft: it's the perfect shop calculator - just the right size to keep handy at the mill or the lathe
04:08 PM roycroft: yes, i'm thinking that can be removed
04:08 PM XXCoder: though risky to remove as it may be damaged and hard to re-place
04:08 PM DaViruz: if you're that worried about scratches it's a terrible shop calculator
04:08 PM roycroft: there's probably an indentation on the bezel to locate it
04:08 PM roycroft: it has a case
04:08 PM roycroft: and my machines all have drawers nearby
04:08 PM XXCoder: personally I prefer ti-84 lol
04:09 PM roycroft: right now i'm using some hp 48s in the shop
04:09 PM DaViruz: single line displays are a bother
04:09 PM roycroft: but i don't need big, fancy graphing calculators
04:09 PM roycroft: i'm a die-hard hp guy
04:09 PM roycroft: i think a calculater that does not do rpn is useless :)
04:09 PM roycroft: other think differently though
04:09 PM roycroft: which is why we have ti
04:10 PM DaViruz: truthfully, do you ever use rpn? :)
04:10 PM roycroft: 100% of the time
04:10 PM DaViruz: i said truthfully!
04:10 PM roycroft: i've been using hp calculators since the '70s
04:10 PM roycroft: yes
04:10 PM roycroft: truthfully
04:10 PM roycroft: it's so much easier than trying to do algebraic notation on a calculator
04:10 PM roycroft: just pushing and popping stuff on and off the stack
04:10 PM roycroft: enter equations from left to right
04:10 PM roycroft: no worries about groupings
04:11 PM roycroft: it's really 10x easier than an algebraic notation calculator
04:11 PM DaViruz: i use rpn if i happen to be stuck with it due to some odd circumstance, but i've never been very fluent
04:11 PM XXCoder: same
04:11 PM XXCoder: my ti-84 is same one I used for all my college math classes including calclus
04:11 PM roycroft: 4 enter 7 + 11 enter 3 - x is easy to key in
04:12 PM roycroft: (4+7)x(11-3)= is a lot more work
04:12 PM eeriegeek: I find it very tedious to try to use a non-rpn calculator
04:12 PM roycroft: indeed!
04:12 PM roycroft: heaps of extra unnecessary keystrokes
04:13 PM DaViruz: the odd circumstance is usually that i'm stuck in a terminal with only dc installed :P
04:13 PM roycroft: and if you forget to do a grouping you get to start all over
04:13 PM XXCoder: lol
04:13 PM XXCoder: my calculator I can edit
04:13 PM XXCoder: no need to start all over again
04:13 PM roycroft: it's still more work :)
04:13 PM XXCoder: in fact, for example if I need to find 9 Z locations
04:13 PM roycroft: but i'm done with advocacy now
04:13 PM DaViruz: roycroft: 10 vs 13 button presses
04:13 PM roycroft: i hope you believe that i actually do use rpn 100% o fthe time
04:14 PM roycroft: yes, 30% more work!
04:14 PM XXCoder: all I need to is recall equation and modify part z enter
04:14 PM roycroft: but as i said, for folks who like algebraic notation, that's why ti are there
04:14 PM roycroft: you use your ti
04:14 PM roycroft: i'll use my hp
04:14 PM XXCoder: thats 2 digits change for overall 15 digit or so
04:14 PM roycroft: and we'l each be happy
04:14 PM DaViruz: i don't have a strong opinion either way
04:14 PM DaViruz: i can see that rpn has a lot of advantages
04:14 PM roycroft: in the end, it's what you're used to, for the most part
04:14 PM XXCoder: indeed
04:15 PM XXCoder: both has strong points
04:15 PM roycroft: also
04:15 PM roycroft: this may be the main advantage of an hp
04:15 PM roycroft: most people do not know how to use them
04:15 PM roycroft: so they won't ask to borrow yours
04:16 PM * roycroft likes things that he doesn't have to worry about borrowing out
04:17 PM XXCoder: roycroft: https://www.finishing.com/4000-4199/4148.shtml
04:17 PM DaViruz: is rpn usage common in the US?
04:17 PM XXCoder: my ti-84 is more complex that most people use at work
04:17 PM roycroft: if i could get that logo off and remove the bezel without bending or otherwise damaging either, i could probably clean up the bezel nicely and restore a brushed finish
04:17 PM DaViruz: i think i'd be very hard pressed to find a single person who even knows what it is here
04:17 PM XXCoder: so they dont use mine lol
04:17 PM roycroft: it was until about 1990, daviruz
04:17 PM DaViruz: i see
04:17 PM roycroft: that's when ti "took over" the scientific and engineering fields
04:18 PM roycroft: until then *everybody* in science or engineering had an hp (or a slide rule, for the holdouts)
04:18 PM roycroft: and actually, most folks i know in engineering still have hp calculators
04:18 PM Deejay: gn8
04:18 PM roycroft: i use a 32sii as my daily calculator, and i think it's perhaps the most versatile hp ever
04:18 PM nos: I use RPN. Got an app.
04:18 PM XXCoder: probably same era ti become a requirement in school
04:18 PM roycroft: and as i said, i have the 48gs in the shop right now
04:19 PM roycroft: and a 49gx in my office
04:19 PM roycroft: and this 11c that's looking for a home
04:19 PM DaViruz: the only portable calculator i use nowadays is the phone. and it gets me in a bad mood every time
04:19 PM XXCoder: DaViruz: I think theres ti-84 emulator for phpne now lol
04:20 PM DaViruz: heck, anything i have to use the phone for gets me in a bad mood
04:20 PM nos: https://www.microsoft.com/en-us/store/p/rpn9/9nblggh0k773
04:20 PM roycroft: i was thinking about a maroon scotch-brite pad
04:20 PM roycroft: that article xxcoder linked to suggests that
04:20 PM XXCoder: one of respondant menioned that yes
04:21 PM XXCoder: other one menions revere pan cleaner
04:21 PM roycroft: i just wonder if it's too agressive for aluminium
04:21 PM roycroft: i have a white scotch-brite pad
04:21 PM roycroft: which is not terribly aggressive
04:21 PM XXCoder: that one he tried on brushed alum ref and it was nice result apparently.
04:21 PM roycroft: but my concern about that is that it might tend to polish too much, and i want to retain the brushed look
04:21 PM XXCoder: it would
04:22 PM roycroft: even 320 grit wet and dry might be too fine for the brushed look
04:22 PM roycroft: of course, if i polish out all the scratches i could always brush it later
04:23 PM XXCoder: https://www.amazon.com/dp/B00080QDV2/ref=nosim?tag=finishingcominc
04:23 PM roycroft: i think i need to go to the goodwill and get a couple $2 junker calculators and do some testing on those
04:23 PM XXCoder: thats what guy recommanded to fix ref brushed surface
04:25 PM roycroft: the glass over the display has some kind of gunk on it too
04:25 PM roycroft: like varnish or something
04:25 PM roycroft: i'd like to remove that, and it would probably be difficult to get it all off while mounted
04:26 PM roycroft: so if i can remove the bezel assembly without damaging it i should be able to get the glass off to clean it up properly
04:26 PM XXCoder: that may be tough to do, but same time yours is older so likely easier
04:27 PM roycroft: unfortunately hp had a tendency to make things really well back then
04:27 PM roycroft: so it might be difficult in spite of its age
04:27 PM roycroft: mayhap *because* of its age
04:28 PM DaViruz: i have a friend who is a hp calculator collector, he has a few odd ones
04:28 PM DaViruz: on that is specific for calculating artillery ballistics
04:28 PM roycroft: i saw an hp 65 for sale a while back with a really nice set of programs
04:28 PM XXCoder: but older tend to be more designed for repairing
04:29 PM roycroft: it was the first programmable calculator (first period, not first hp)
04:29 PM roycroft: and it stored the programs on magnetic cards
04:29 PM roycroft: the one i saw had a card that was labeled "moon landing simulator"
04:29 PM XXCoder: unfortunately magnetic typedata storage fades
04:29 PM roycroft: hand labeled - it was not an hp-provided program
04:29 PM XXCoder: if you have it, suggest somehow make digital copies
04:30 PM roycroft: it has a bunch of civil engineering programs though
04:30 PM roycroft: i don't have it
04:30 PM roycroft: i saw it
04:30 PM roycroft: it was $695
04:30 PM roycroft: i like old hp calculators
04:30 PM roycroft: but i don't like them $695 worth
04:30 PM XXCoder: https://wabbit.codeplex.com/releases/view/44625
04:30 PM XXCoder: ti-84 emulator lol
04:30 PM XXCoder: though need to download rom somewhere else
04:30 PM roycroft: the 65 came out when i was either in high school or just after i graduated
04:31 PM roycroft: and i started college with a slide rule, as electronic calculators were still too expensive for college students then
04:31 PM eeriegeek: http://imgur.com/a/Lm7ty
04:31 PM XXCoder: I have dad's slide rule somewhere
04:31 PM XXCoder: my bro has bigger version from dad also
04:32 PM roycroft: i have a few still
04:32 PM XXCoder: it was what 2 feet long?
04:32 PM roycroft: i can hardly use them any more though - it's been so long
04:32 PM roycroft: but i was pretty adept at using one when i was in high school/college
04:32 PM roycroft: we used the cnc math handbook a lot too, to look up trig tables et al.
04:36 PM XXCoder: saved source code because that site is shutting down
04:37 PM XXCoder: laters
04:47 PM JT-Shop: that cake pan machined like crap so soft it just pushed the material up and out
05:04 PM dioz: anyone here ever run hot to finish a product?
05:04 PM dioz: then end up piling up a machine becauwe of it? hah!
05:05 PM dioz: speed over tool life?
05:06 PM dioz: what material bit doesn't need lubricant? what?
05:07 PM roycroft: my new ultrasonic cleaner will be here shortly
05:07 PM roycroft: it should be really nice to have, as long as it's not too noisy
05:07 PM roycroft: my current one is 2L, and it's pretty irritating to stand near
05:08 PM roycroft: the new one is 22L, but i'm going to locate it on the other side of my shop, away from workbenches
05:08 PM roycroft: as long as it's not too much louder than the current one it should be ok
05:08 PM roycroft: otherwise it might end up living in the welding shop, which i would not like
05:09 PM dioz: you have me on ignore i think
05:11 PM pink_vampire: hi
05:44 PM phipli: progress setting up the lathe
05:45 PM phipli: the faceplate is straighter than the chuck, even though the faceplate is from another lathe and the chuck is from this one
05:45 PM phipli: the tailstock is vertically misaligned with the headstock... and there isn't vertical alignment without skimming / shimming (can't remember which way it was)
05:46 PM phipli: there is reasonable vibration from the bull gear...
05:46 PM phipli: sigh.
05:46 PM nos: phipli: Is the lathe flat on the ground? A twist will show up like that.
05:47 PM phipli: nos - it is pretty flat - to within half a washer
05:47 PM phipli: (I hadn't got anything thinner to shim it with :s)
05:48 PM phipli: and "level" wouldn't explain the wobble in the chuck or the dish in the faceplate
05:48 PM nos: Do you have a machinist's spirit level?
05:48 PM phipli: nope
05:48 PM phipli: been through that
05:48 PM phipli: I've spent about £200 on kit trying to get this lump that my dad turned up with having spent £60 on it
05:48 PM nos: I wonder if the digital ones are accurate enough for a job like this...
05:49 PM phipli: if I spend much more I might as well have just bought a working one
05:49 PM phipli: (I know £200 is naff all, but I didn't require one, and so it is a curiosity)
05:50 PM phipli: on the plus side, here is a happy duck : https://imgur.com/aWVCfAU
05:50 PM phipli: or goose actually now that I pay attention
05:50 PM nos: Does indexing the face plate to other bolt holes alter how true it is?
05:51 PM nos: lol
05:51 PM phipli: on average I have the faceplate about right
05:52 PM phipli: there is a minor eccentricity, and a low point nearish the middle
05:52 PM nos: I mean, are both off and just compensating one another?
05:53 PM phipli: between what and what sorry?
05:53 PM nos: The spindle axle and the face plate.
05:54 PM phipli: I can rotate and slightly vary the clamping force on the headstock... the faceplate is single part, screws on
05:54 PM nos: ah...
05:55 PM phipli: bearings might be worn, could be making the spindle low, if that was the way round it was (I'll stick the centres back in tomorrow and write it down)
05:56 PM JT-Shop: dang I think I came up with a way to mount this push button on the cylinder
05:56 PM JT-Shop: can you wobble the spindle?
05:56 PM phipli: box section and a hole saw?
05:56 PM phipli: JT-Shop: not since I tightened it :)
05:57 PM phipli: there are screws on each shell bearing
05:57 PM JT-Shop: 19mm push button in 1.375" round stock
05:57 PM phipli: braze a washer in?
05:58 PM JT-Shop: alum..
05:58 PM JT-Shop: has to be serviceable, I have to design and build a few
05:58 PM nos: mmm... microwave baked potato :)
05:59 PM phipli: nos : that isn't a practical solution to mounting a switch :p
05:59 PM nos: It is deliscious though.
05:59 PM phipli: hehe
05:59 PM nos: Cheap, wholesome snack.
06:01 PM JT-Shop: mounting plate looks like a little exhaust gasket
06:02 PM phipli: JT-Shop: cut out a square from the cylinder, bend a rectangle to fit and rivet the top and bottom of it (beyond the cut out square)?
06:02 PM phipli: what did you do?
06:02 PM phipli: (by bend the rectangle I mean like two 30 deg bends, like a lazy u channel)
06:02 PM JT-Shop: this is a remote handle to run a big nut driver
06:03 PM JT-Shop: needs to be hand friendly :)
06:03 PM phipli: are you trying to put the button in the end of it?
06:04 PM JT-Shop: on the side like you would grab a handle bar and want to push a button to do something
06:05 PM JT-Shop: and the button has a weird thread so tapping is not possible :(
06:05 PM nos: night
06:05 PM phipli: google is your friend : https://tinyurl.com/yaboq2j3
06:05 PM * LeelooMinai goes to see if it's possible to 90 deg bend 2mm (14 gauge) 4 inches long steel with a wise
06:05 PM phipli: LeelooMinai: apply fire
06:06 PM JT-Shop: damn
06:06 PM phipli: people generally seem to go for a clamp
06:07 PM phipli: could you just buy one of those buttons? Save the work?
06:07 PM JT-Shop: the problem with them are they might not have a million cycle rating, this thing gets pushed every few seconds all day long
06:07 PM * phipli nods
06:08 PM JT-Shop: that is one hell of a selection though
06:09 PM JT-Shop: the pushbutton looks kinda like this https://www.amazon.com/Yueton-Waterproof-Momentary-Reactable-Terminals/dp/B0131XF9KS/ref=sr_1_6?ie=UTF8&qid=1497566302&sr=8-6&keywords=waterproof+push+button
06:09 PM LeelooMinai: Hmm
06:09 PM phipli: quite nice looking : https://purposebuiltmoto.com/wp-content/uploads/2016/10/1-inch-Push-button-silver-10.jpg
06:10 PM LeelooMinai: The answer is "yes and no" it seems:)
06:10 PM LeelooMinai: http://i.imgur.com/Ylhj6Ch.jpg
06:11 PM phipli: I have some like that - some of these : https://www.seeedstudio.com/16mm-Anti-vandal-Metal-Push-Button-Royal-Blue-p-1308.html
06:11 PM phipli: LeelooMinai: what did you use?
06:11 PM phipli: oh yeah
06:11 PM phipli: vise
06:11 PM LeelooMinai: Well, I used this cheap thing: https://www.princessauto.com/en/detail/5-in-vise-mount-bending-brake/A-p8663759e
06:12 PM phipli: I've got something similar
06:12 PM LeelooMinai: And, I had to use a steel pipe to get beter levarage on the vise - I could not to it by hand, well, not without "great and dangerous effort"
06:13 PM phipli: mine look like this : http://static.axminster.co.uk/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/3/0/300371_xl.jpg
06:13 PM phipli: basically the same
06:13 PM LeelooMinai: But, this was not even rated for 2mm, so I am pretty happy with this thing.
06:13 PM phipli: how thick was the metal?
06:13 PM phipli: sigh
06:13 PM LeelooMinai: Right, seems same design - mine has those bagnets there too.
06:13 PM phipli: I have a short memory
06:13 PM LeelooMinai: 14 gauge = 2mm
06:14 PM LeelooMinai: Hmm, o, they say 14 gauge is max... ok then I guess...
06:15 PM LeelooMinai: But this will be pretty useful probably - I got it since I want to weld some "fixtures" made from sheet metal to my CNC stand.
06:15 PM LeelooMinai: Of course a proper brake is better - one reason being that you are not limited on the depth of insertion, but those are expensive.
06:17 PM phipli: You can do quite well with some steel, clamps and door hinges I'm lead to believe
06:17 PM phipli: It you don't mind a bit more set up time
06:17 PM LeelooMinai: Right, I saw some videos on youtube with people doing weird things, but it was always "yeah right - I am not doing that each time I want to bend something":)
06:18 PM phipli: :)
06:18 PM phipli: the vise things are more than enough for me.
06:18 PM phipli: making small brackets etc.
06:18 PM LeelooMinai: But many times I wanted to bend some metal thin part quickly and I wish I had a tool like this.
06:19 PM LeelooMinai: Right, brakets, etc.
06:19 PM phipli: I used to use pieces of wood, clamps and the edge of a table...
06:19 PM dioz: 14 gauge is 2mm?
06:20 PM phipli: even just turning a sheet into a 'u' section to give it some rigidity
06:20 PM dioz: phipli: they call that cross breaking
06:20 PM LeelooMinai: Well, I saw one guy making a "bend" by first making a grove in 1/4 steel with an angle grinder then bending and welding:)
06:20 PM phipli: dioz: 1.897mm
06:20 PM phipli: the internet tells me
06:21 PM LeelooMinai: Well, since of course making gauges was not enough for them to confuse people, seems they even are different depending on the material type, steel type, etc.:/
06:21 PM phipli: heh
06:21 PM LeelooMinai: This is galvanized steel
06:22 PM phipli: stupid units
06:22 PM LeelooMinai: And I measured it with callipers to be 2mm, but it has marked #14 on it in one place
06:22 PM phipli: 1.994mm in galvanised steel
06:22 PM LeelooMinai: Right, so it checks.
06:23 PM phipli: actually a kind of handy random website : http://www.custompartnet.com/sheet-metal-gauge
06:23 PM phipli: menu for the material type
06:23 PM dioz: you mean galv iron?
06:23 PM dioz: mild steel?
06:23 PM LeelooMinai: I meant what I wrote - galvanized sateel
06:23 PM LeelooMinai: steel*
06:24 PM dioz: *shrug*
06:24 PM phipli: less than a mm for Zinc... weird, weird units
06:24 PM LeelooMinai: I think this was from one of those "hot dog carts"
06:24 PM phipli: anyhow
06:24 PM phipli: I'm vanishing for the night
06:24 PM phipli: night folks
06:24 PM JT-Shop: night
06:25 PM LeelooMinai: The pipe sizes are even weirder:/
06:26 PM dioz: you aren't supposed to tool stock if you don't know what it is
06:26 PM LeelooMinai: dioz: And you aren't supposed to write things that do not make sense:p
06:26 PM dioz: like if some random walked in with some 1/4 in random fucking plate and aksed me to give it a sheer
06:26 PM dioz: i'd be like "nope"
06:28 PM dioz: how do i determine feed rates if i dhnno what it is?
06:28 PM dioz: i could spark test it i guess
06:28 PM dioz: get a grinding wheel and see how she sparks
06:29 PM LeelooMinai: By using your excellent investigative skills and superior ability to adjust to any situation.
06:30 PM dioz: naw. we do it by the book
06:30 PM dioz: we don't "adjust"
06:31 PM dioz: off book results in inconsistant work
06:31 PM LeelooMinai: That's why you will be replaced by robots one day, while people who can go out of a book not:)
06:31 PM dioz: will i?
06:32 PM LeelooMinai: It's a possibility
06:33 PM dioz: i'm not sure why someone would wanna reinvent the wheel.... or think they're smart enough too.
06:33 PM LeelooMinai: You will work at some company and one day some manager will do some calculations and say "Hey, we can replace that Bob goy with this new machine they made - it's expensive, but less cost after all the calculations":)
06:33 PM LeelooMinai: "The machine is certified to follow all the book rules"
06:34 PM LeelooMinai: "We well name it Bob II"
06:34 PM dioz: that isn't rrally the concept we're discussing.
06:34 PM dioz: but okay
06:35 PM LeelooMinai: dioz: You think I am discussing anything? I am watching some YouTube vido:p
06:35 PM dioz: oh so this back and forth isn't your true idea on the matter
06:35 PM dioz: well that's good to hear
06:35 PM dioz: you had me scared for a moment
06:35 PM LeelooMinai: That's a really bed reasoning there you have...
06:36 PM LeelooMinai: bad*
06:36 PM dioz: what is?
06:36 PM LeelooMinai: Assuming that if someone multitasks, then they cannot express their "true" ideas.
06:36 PM dioz: you seem to talk out of both sides of your mouth hey?
06:36 PM LeelooMinai: dioz: It's called "keyboard" - you should try it one day:)
06:39 PM dioz: *shrug* if you don't know the basics... yeesh
06:39 PM LeelooMinai: :( https://www.amazon.ca/Te-Co-20609-T-Slot-Small-Parts/dp/B01HDY23A0
06:39 PM LeelooMinai: There's something wrong with that company
06:40 PM dioz: LeelooMinai: what kind of lubricant should i use on my bandsaw?
06:40 PM JT-Shop: bandaid
06:40 PM LeelooMinai: dioz: The proper one.
06:40 PM JT-Shop: oh you didn't ask me
06:41 PM dioz: JT-Shop: would you sheer random material?
06:41 PM JT-Shop: nope, a shear is worth too much
06:41 PM dioz: you ever seen tooling explode?
06:42 PM dioz: like a v-die in a press?
06:42 PM LeelooMinai: I wonder why dioz askes that. Did anyone here suggest to sheer a random material?
06:42 PM JT-Shop: I've seen grinding wheels explode
06:42 PM JT-Shop: from a distance
06:42 PM dioz: zip disks?
06:42 PM dioz: or like.. a cutoff disk?
06:42 PM Tom_itx: i've seen the results of a press flywheel coming apart and going thru a wall
06:43 PM JT-Shop: 16" x 3" iirc
06:43 PM LeelooMinai: dioz: If you are such a specialist tell me what one should check before using a cutoff disk:)
06:43 PM Tom_itx: ~4' flywheel
06:43 PM dioz: make sure all guards are in place
06:43 PM dioz: hah!
06:43 PM LeelooMinai: dioz: No, I mean about the disk itself.
06:43 PM sync: check that it is not expired
06:43 PM sync: but #yolo
06:43 PM Tom_itx: here we go again...
06:44 PM JT-Shop: lol
06:44 PM LeelooMinai: You see, dioz does not even know that:)
06:44 PM Tom_itx: don't check for anything just use it and watch it explode in your face
06:44 PM dioz: tbh i go theough cuttoff disks so much i don't see how they'd be expired
06:44 PM LeelooMinai: dioz: It was not in "the book"? :p
06:44 PM Tom_itx: yeah if you don't keep it in the frig you need to check the expiration date
06:45 PM dioz: i cut a lot of high velocity duct up
06:45 PM dioz: and lots of ready rod
06:45 PM Tom_itx: JT-Shop, who goes to bed first, you or the chickens?
06:45 PM dioz: i got a hand held bandsaw now though
06:45 PM Tom_itx: storms moving in here
06:46 PM JT-Shop: 6 weeks till the eggs start to pop out
06:46 PM Tom_itx: cool
06:46 PM JT-Shop: chickens
06:46 PM dioz: i totally don't think cut off dicska have expirey dates
06:46 PM Tom_itx: not gonna eat em all yet ehh?
06:46 PM dioz: i think that's a bs
06:46 PM Tom_itx: naw it's a thing
06:46 PM JT-Shop: the chickens or the eggs?
06:46 PM Tom_itx: eggs
06:46 PM sync: dioz: don't be so sure
06:46 PM dioz: it ain't a thinkg.
06:46 PM kyle____: oh boy it's dioz again
06:47 PM kyle____: the expert of everything
06:47 PM JT-Shop: I eat 3 on saturday and sunday and wife eats 1
06:47 PM JT-Shop: rest will be given away to friends
06:47 PM kyle____: so confident in his ability is he that he must tell us all constantly
06:47 PM Tom_itx: hasn't welded zinc enough yet
06:47 PM dioz: lol
06:47 PM LeelooMinai: dioz: Tip #4 from The Book of Trolling: try mixing trolls and facts, so that you keep people confused:p
06:48 PM dioz: the galv will kill you basically instantly
06:48 PM dioz: i heard
06:48 PM * JT-Shop wonders where the wife is... she is kinda late getting home
06:48 PM kyle____: alternatively, if you're not trolling, try being a little more humble, it's a lot more endearing than being a blowhard
06:48 PM Tom_itx: naw, it's a slow painful death
06:48 PM Tom_itx: like drinking mercury
06:48 PM sync: en12413 disagrees with you dioz
06:48 PM JT-Shop: you could make sinkers in a closet I know the result of that...
06:48 PM dioz: kyle____: at least i know what an e6011 is.
06:49 PM kyle____: as do I, thanks
06:49 PM dioz: and what all the numbers mean
06:49 PM kyle____: mhm I know ALL the numbers
06:49 PM kyle____: every single one
06:49 PM * Tom_itx checks the colorful spot on the radar
06:49 PM dioz: didn't the other night
06:49 PM JT-Shop: Tom_itx: you got rain?
06:49 PM Tom_itx: not yet
06:49 PM kyle____: ignoring you isn't any indication of what I know ;)
06:49 PM Tom_itx: looks like it may go north of me
06:50 PM kyle____: it takes a simple mind to confuse the two concepts
06:50 PM dioz: at least i inow what smaw means
06:50 PM LeelooMinai: Hmm, I bought flappy disks for grinder so I can remove the galvanized part before welding.
06:50 PM dioz: and the differwnce between dc+ and dc-
06:50 PM Tom_itx: had lotsa noise last night but no skyfall
06:50 PM kyle____: do you want a cookie for it?
06:50 PM dioz: LeelooMinai: i just use acid
06:50 PM dioz: takes less time
06:50 PM JT-Shop: looks like Sunday for some rain here
06:50 PM LeelooMinai: dioz: Nowadays a 5 yo kid can now what it means in about 1 minute:)
06:51 PM LeelooMinai: know*
06:51 PM kyle____: indeed, information is cheap
06:51 PM LeelooMinai: So is trolling:)
06:51 PM Tom_itx: you're a pro
06:51 PM dioz: i'm also a champ with computers btw
06:51 PM * JT-Shop wanders down to discuss some deep topics with the chickens...
06:52 PM sync: dioz: tell me why there is a date stamped in my grinding discs then?
06:52 PM kyle____: I bet dioz doesn't know what an interrupt service routine is
06:52 PM dioz: i used to be a dual threat system and network admin
06:52 PM dioz: now i swing a hammer
06:52 PM dioz: sync: manufavturer dates
06:52 PM dioz: when it was made
06:52 PM kyle____: honestly, why are you so concerned with what we think of you?
06:52 PM sync: dioz: incorrect
06:53 PM LeelooMinai: "... but they fired me after deciding that I am a threat to the system by myslef" :p
06:53 PM dioz: sync: lol. i ain't never once looked at a cut off disk close enough i don't think
06:53 PM dioz: if they have an expiry date... news to me.
06:53 PM sync: so you don't do it by the book
06:53 PM dioz: i can admit i'm wrong
06:53 PM dioz: i am wrong!.
06:53 PM dioz: look athow wrong i am
06:54 PM dioz: such a moron for being wrong. yeesh
06:54 PM dioz: i still think you fuckin with me though
06:54 PM dioz: i'll check it out in a bit though
06:54 PM Tom_itx: ask google
06:54 PM Tom_itx: i bet it knows
06:54 PM LeelooMinai: Rule $5: Never make oneself look hysterical:)
06:55 PM dioz: if i was at work i'd say sonething like "yougotta be fist fucking me"
06:55 PM Tom_itx: or be so convincing nobody notices
06:55 PM sync: as you do it by the book and are a pro you probably have consulted the manufacturers information and applicable legislation before using a tool
06:55 PM dioz: lol legislation
06:55 PM kyle____: so edgy
06:56 PM dioz: sync: i never once claimed to be an expert at anything
06:56 PM dioz: i highlighted specific information
06:56 PM dioz: people refute. i know i'm right
06:56 PM dioz: so i debate
06:56 PM dioz: i'm okay with being wrong
06:56 PM dioz: some aren't
06:57 PM LeelooMinai: I can admit I am wrong too. In fact, I once did, but I was wrong:p
06:57 PM dioz: i'm wrong a lot. like today i used pi * d instead of pi r ^ 2
06:57 PM dioz: and i got mad when someone told me my math was wrong
06:57 PM dioz: they showed me my error
06:57 PM dioz: i said they were right
06:57 PM dioz: we moved on
06:58 PM LeelooMinai: "I moved to my room and my 4yo borther to his"
06:58 PM kyle____: wow he's really emotionally maturing
06:58 PM dioz: LeelooMinai: how are your roomates btw?
06:58 PM LeelooMinai: dioz: How is your space helmet?
06:59 PM dioz: LeelooMinai: you a canuck?
06:59 PM dioz: or is p-auto in the usaia too?
06:59 PM LeelooMinai: I am in Ontario.
07:00 PM LeelooMinai: Don't know if they are un US - maybe.
07:00 PM dioz: do you know david rock?
07:00 PM LeelooMinai: No...
07:00 PM dioz: LeelooMinai: have you wver heard of davids farm?
07:00 PM dioz: ah. nvm
07:00 PM dioz: intario is cool. i was there last summer
07:00 PM dioz: i drove to quebec
07:01 PM dioz: LeelooMinai: do you know who jordan peterson is?
07:02 PM * LeelooMinai pulls out a fiberglass 4 by 6 foot blanked from the package
07:02 PM dioz: i love all the watwrfalls in hamilton area
07:02 PM dioz: beautiful... other than all the chainlink
07:02 PM LeelooMinai: "hmm, I could use it to hind under during flame wars"
07:02 PM dioz: morons fall into the water so the governmwnt chain links all the waterfalls
07:02 PM LeelooMinai: hide*
07:03 PM dioz: didn't a couple morons die last week cause of waterfall?
07:03 PM LeelooMinai: Not sure why you though about "morons" first - what about small children...
07:03 PM dioz: small childrens are morons...
07:03 PM dioz: they don't know much
07:03 PM Tom_itx: they do
07:04 PM LeelooMinai: I see, still Troll 101:)
07:04 PM LeelooMinai: Nowadays children can be as smart as a president of a country.
07:04 PM dioz: i've never once met a child i've enjoyed talkig with
07:04 PM dioz: it's always all about them
07:04 PM dioz: they're so needy
07:05 PM dioz: LeelooMinai: we get it... you're a liberal
07:05 PM dioz: borderline socialist
07:05 PM dioz: might as well be a communist in my eyes
07:05 PM LeelooMinai: Right, I left a coiuntry running from communism to be a communist:p
07:06 PM dioz: well you are aware how the political spectrum works right?
07:06 PM dioz: i know you're only a cs major but cmon
07:06 PM LeelooMinai: I wish I was unaware of anything related to politics.
07:07 PM dioz: might as well be
07:07 PM LeelooMinai: It's much saner for the mental health.
07:08 PM dioz: tell me all the paets of a twist drill bit
07:08 PM dioz: flutes
07:08 PM dioz: chisel
07:08 PM LeelooMinai: Ok, I have a fireproof apron, blanket, slleve-thingies, and even a cap to have under the helmet - I am ready for tomorrow for a MIG test.
07:08 PM dioz: cutting lips
07:09 PM dioz: sweet!
07:09 PM dioz: glue gun is awesome
07:09 PM dioz: i wanna tig though
07:09 PM dioz: i do lots of thin gauge
07:09 PM kyle____: "it's always all about them"
07:09 PM LeelooMinai: Eight, but this MIG cost me $200 and TIG would be $1k:)
07:10 PM dioz: LeelooMinai: that's fine with me.
07:10 PM LeelooMinai: I can add gas to it, but from what I have seen that would be extra $300 at least.
07:10 PM dioz: i am so cheep the moths put on 2 pairs of sunglasses when i open my wallet
07:10 PM LeelooMinai: dioz: Is that some saying from your country?
07:11 PM dioz: it's better than what the other guys say
07:12 PM dioz: btw. my country... is your country
07:12 PM dioz: only difference is i was born here
07:12 PM LeelooMinai: What do you mean? You said you are from scandinavian country, no?
07:12 PM dioz: i said i'm a viking
07:13 PM LeelooMinai: ...
07:13 PM LeelooMinai: Afaik that's where Vikings lived:p
07:13 PM kyle____: finland?
07:13 PM LeelooMinai: Well, yes, that's scandinavia
07:14 PM kyle____: he's connected to a finnish freenode server
07:14 PM kyle____: not that that's saying much, but it's unlikely if he's in the US
07:14 PM LeelooMinai: Right, well, then I don't know what he is talking about as I am Polish/Canadian:)
07:15 PM kyle____: I think it's probably just some pseudoracist babble
07:15 PM dioz: what?
07:15 PM dioz: i live in canada. my lineage is as such (viking)
07:16 PM dioz: how is thay racism?
07:16 PM dioz: lol
07:16 PM dioz: and i'm the troll!
07:16 PM LeelooMinai: He is a viking using finish server living in Canada.
07:16 PM dioz: saskatchewan. manitoba. alberta. ontario. bc.
07:16 PM LeelooMinai: dioz: You remind me someone from here...
07:17 PM LeelooMinai: dioz: What was his name... zeeshan? :)
07:17 PM dioz: i drove theough winnipeg and thunder bay to get to hamilton.
07:19 PM LeelooMinai: As to having Viking lineage, that's probably pretty common in some areas, like northern GB:)
07:20 PM LeelooMinai: Not sure how people know that though - sans DNA testing.
07:27 PM dioz: what are you trying to say?
07:28 PM LeelooMinai: I already wrote it, don't have to try...
07:30 PM dioz: i'm not sure what you're asserting
07:30 PM LeelooMinai: Just wondering how people are sure that they have Viking lineage.
07:31 PM dioz: you sure?
07:32 PM dioz: seemed like some other supposition you were trying to make
07:32 PM dioz: but i could be wrong
07:32 PM LeelooMinai: Earlier I was wondering if you are zeeshan using another nick.
07:33 PM dioz: i think we should both be banned
07:33 PM LeelooMinai: He is not here though:p
07:33 PM dioz: me and you
07:34 PM LeelooMinai: Right, go kamikadze - good plan.
07:52 PM LeelooMinai: Hmm, I wonder if instead of squaring the tend of my aluminum axis beams (they are 2.5 by 2.5 inches), using something like that JB Weld thing + clink wrap to "match" the beam end to the steel angle would not work better.
07:52 PM LeelooMinai: clink=cling
07:53 PM LeelooMinai: They write it can be machined and used on aluminum and other metals, and is "strong".
07:53 PM LeelooMinai: So I assume it's some kind of epoxy with metal particles inside or something like that (?)
07:55 PM LeelooMinai: Hmm, "tensile strengh 3900 PSI"
07:55 PM LeelooMinai: That sounds bad.
08:11 PM robo: hi all, beginner here. im looking to cut 2 holes in a sheet of mdf. i have a model in fusion 360 but struggling with the CAM part. does anyone know of a good tutorial geared towards a router + linuxcnc + fusion 360? i have most of it down except the setup and tool paths.
08:12 PM LeelooMinai: robo: I would check youtube videos from NYC CNC and Lars Christiansen - there are some about CAM and they cover basics.
08:12 PM LeelooMinai: robo: https://www.youtube.com/watch?v=6FzbZNhey2w
08:13 PM LeelooMinai: And https://www.youtube.com/watch?v=VEuD31byPxk
08:13 PM robo: beautiful, thank you @LeelooMinai
08:14 PM LeelooMinai: I would just search for Fusion CAM in youtube - a lot of videos will come up. But that Christiansen guy is pretty good.
08:26 PM robo: I guess also, I'm wondering if anyone has had issues using cncroutparts universal dust shoe fusion 360 in linuxcnc - it throws toolpath exceed limit errors. i tried a few different post processes and got the same.
08:27 PM LeelooMinai: Is that weird name a name for post processor?
08:51 PM robo: oh sorry, cncrouterparts.com has a dust shoe project/model for fusion 360.
08:51 PM robo: i managed to simulate in fusion 360 and it looks good - thanks for the help. wish me luck.
09:10 PM dioz: 3900 psi tensile strength isn't "not bad"
09:10 PM dioz: that's horriblr
09:12 PM LeelooMinai: dioz: Your reading skills are horrible too:p
09:14 PM dioz: nope.
09:15 PM dioz: but i could see how you'd think that... given your apparent condition
09:21 PM jdh: robo: did you touch off before running? what size does it show in the preview?
09:54 PM robo: jdh: I'm dealing with the Z now - evidently tool size matters
09:54 PM LeelooMinai: robo: I had once problem with post processor for linuxcnc that was assuming z's zero is at the top.
09:55 PM LeelooMinai: And it used that place as "safe space" for tool changes, end position, etc.
09:55 PM LeelooMinai: And I had z at the bottom, so it would try to go through the workpiece...
09:58 PM robo: I may have my conf with z inverted
09:59 PM LeelooMinai: Watch for the arrow colors - of course linuxcnc decided to use illogical scheme instead of XYZ = RGB, like Fusion has.
09:59 PM robo: but back in fusion 360 - im struggling to find a tool close to my router bit...
10:00 PM LeelooMinai: Just add it to your local database in Fusion.
10:00 PM robo: also how does "overall length" come in to play w/r/t mounting in the collet?
10:01 PM LeelooMinai: robo: When you click on the fields it will highlight with yellow what it covers.
10:01 PM LeelooMinai: Also, model your collet exactly imo. You just enter coordinates of a cross section of it in one of the tabs.
10:02 PM LeelooMinai: Overall length I believe is just total length of the endmill.
10:02 PM robo: ah body length
10:02 PM LeelooMinai: But some of it will be inside the collet.
10:04 PM LeelooMinai: robo: If you model your collet/spindle, you will get better sense of the preview. Like I did here: https://i.imgur.com/L37GHOG.png
10:04 PM LeelooMinai: Also, this will be taken into account when avoiding sollisions, so it's worth doing.
10:05 PM LeelooMinai: collisions*
10:28 PM CaptHindsight: the Clausing doesn't do too bad of a job https://imagebin.ca/v/3Q7yFfpDit7R
10:31 PM connor_goodwolf: is there a recommended list of software for creating and generating gcode for CNC?
10:33 PM LeelooMinai: connor_goodwolf: By hand or by CAD?
10:33 PM connor_goodwolf: by CAD
10:34 PM LeelooMinai: I recomment Fusion360, but that's my personal opinion:)
10:34 PM connor_goodwolf: I was looking at fusion 360.. looks like it can generate it? https://knowledge.autodesk.com/support/autodesk-hsm/troubleshooting/caas/sfdcarticles/sfdcarticles/How-to-generate-G-code-from-a-sketch.html
10:34 PM LeelooMinai: t=d
10:34 PM LeelooMinai: Yes, it has CAM with a number of postprocessors, including olinuxcnc
10:34 PM CaptHindsight: CAM
10:34 PM connor_goodwolf: I'm also looking for the best converter from KiCAD
10:35 PM CaptHindsight: what are you starting with? ideas, CAD, parametric models, images??
10:35 PM LeelooMinai: connor_goodwolf: Well, Fusion is CAD+CAM, so potato/tomato:)
10:35 PM LeelooMinai: Er, CaptHindsight*
10:35 PM connor_goodwolf: CaptHindsight: I just want to do a test run right now, then move on to PCBs
10:36 PM LeelooMinai: Are you connor wolf from YT?
10:36 PM connor_goodwolf: I've a chinese CNC machine, working on building https://github.com/CarlosGS/Cyclone-PCB-Factory
10:36 PM connor_goodwolf: LeelooMinai: nein
10:37 PM LeelooMinai: Hmm, ok
10:37 PM connor_goodwolf: ah,I can use bCNC
10:37 PM connor_goodwolf: sweet
10:48 PM robo: im closer and made some dust BUT i had to touch off on the spoil board and tell linuxcnc z is -1"
10:49 PM robo: so im guessing i need to (un) invert my z in conf
10:50 PM robo: up is positive currently for z
10:50 PM LeelooMinai: That's what it is supposed to be.
10:50 PM malcom2073: robo: That's correct
10:50 PM malcom2073: down is negative, top of part is (usually) zero
10:51 PM LeelooMinai: robo: Fusion CAM assumes Z zero is at the top, but below are negative values.
10:51 PM LeelooMinai: So the axis is normal (up)
10:52 PM malcom2073: That has the added benefit that z 0 is fully retracted from the workpiece
10:52 PM malcom2073: machine space
10:52 PM robo: ok yeah i home all the way up
10:53 PM robo: but how do i fix what i have now? when i touch off on the stock it tries to cut inches above where I want it to
10:53 PM LeelooMinai: robo: But you know about local coordinates?
10:54 PM robo: not really, emc is set to g54
10:54 PM LeelooMinai: robo: CAM will generate everything relative to local coordinates, not global.
10:54 PM LeelooMinai: Right, g54 is a "virtual"/local coordinate system - usually relative to some corner of the worpiece.
10:55 PM LeelooMinai: You need to read upon it, or you will be very confused.
10:55 PM LeelooMinai: Your homing zero is in global/machine coordinates.
10:56 PM LeelooMinai: You cannot even use those for G commands unless you explicitelly prepend the command telling that you want global coordinates.
10:56 PM CaptHindsight: and the motor just burned up :(
10:56 PM malcom2073: CaptHindsight: on the clausing? It was cutting so smooth!
10:57 PM CaptHindsight: yup, ran it at top speed and smoke came out
10:57 PM malcom2073: doh
10:58 PM CaptHindsight: going to change out to 3phase with VFD
10:58 PM malcom2073: Nice
10:59 PM CaptHindsight: i had just finished a project with it earlier
10:59 PM robo: Leeloominai: I'd rather it cut when I touch off on the workpiece but the tool path is too high, even with corrected tool dimenssions - ideas on how to fix?
11:00 PM LeelooMinai: robo: Short story is, when you look at g-code the CAM generated. There will be G54 command somewhere. From that point on all the movements are relative to that coordinate system, which implies that you better have the origin on it where it should be.
11:00 PM CaptHindsight: going to hide the POT for the VFD in the old hydraulic speed control handle
11:01 PM LeelooMinai: robo: In the Fusion CAM setup, there's a tab where you specify the origin of the stock. Did you do that?
11:01 PM LeelooMinai: That is the G54 origin, unless you override it.
11:02 PM robo: I set origin to model origin (bottom, corner of stock) - should that be top of stock?
11:03 PM LeelooMinai: You need to be precise there - have all the axis match your CNC axis, and be able to set G54 on the machine later so it is in the same point on the stock.
11:03 PM LeelooMinai: robo: Well, touching of to the bottom may be a bit problematic:p
11:03 PM LeelooMinai: Usually people use top left back cornet.
11:03 PM LeelooMinai: corner*
11:04 PM LeelooMinai: Because the fixed jaw of the vise is there.
11:04 PM LeelooMinai: Usually.
11:04 PM robo: that makes sense, ill try that but it seems like it will just try to cut higher
11:05 PM LeelooMinai: It's crucial then linuxcnc has G54 origin in the same place in relation to the stock as in your CAM.
11:05 PM LeelooMinai: than=that
11:06 PM LeelooMinai: Or to be more precise, in relation to the part inside the stock.
11:06 PM LeelooMinai: "the future part" I guess
11:06 PM robo: ok
11:07 PM robo: as for pocket selections - im cutting holes in sheet stock (mdf), do i select the top or bottom for tool path?
11:07 PM LeelooMinai: robo: You have any z touch off device?
11:08 PM LeelooMinai: robo: You select cointour paths. Top is normal - not sure if bottom can be used too.
11:09 PM LeelooMinai: Wear some dust mask for that MDF imo:)
11:09 PM robo: not yet
11:09 PM LeelooMinai: Some nasty stuff in those from what I read.
11:09 PM robo: im cutting a dust shoe...
11:10 PM LeelooMinai: lol
11:10 PM robo: cyclone, 2hp venting outside
11:13 PM LeelooMinai: Automatic z-touch off ftw imo
11:13 PM LeelooMinai: Huge time saver
11:15 PM LeelooMinai: Or even better one of those laser ones - where you can touch off, but also spin the bit and get whole outside profile this way, so correct the diameter, detect broken tools, monitor wear of tools, etc.
11:17 PM robo: that did the trick
11:17 PM robo: THANK YOU
11:17 PM LeelooMinai: ok, np
11:44 PM dioz: idk why i can't get openvswitch and my 2940 to lacp
11:45 PM dioz: i got a fancy dell nic and a fancy intel nic in the server
