12:00 AM CaptHindsight: so it's going to be really dry after being near flood stage
12:04 AM CaptHindsight: like all the rain for summer already fell
12:04 AM Tom_L: been pretty wet here up to the last week or so
12:04 AM XXCoder: so huuuuumid ugh
12:04 AM CaptHindsight: i have to hook up the other 50% of our AC
12:04 AM XXCoder: need to change my ac to drying mode later lol
12:04 AM CaptHindsight: it's dry in here but only stays 5-10 deg below outside temps
12:04 AM XXCoder: finally understood how to properly use dehumid mode
12:04 AM XXCoder: capt its warmer my room than outside now
12:04 AM XXCoder: 78f here outside 73
12:04 AM CaptHindsight: 78 in and outside right now
12:04 AM CaptHindsight: AC will catch up over night
12:04 AM XXCoder: nah it has 5f range
12:04 AM CaptHindsight: but start getting hot in here by 2pm
12:04 AM XXCoder: if it gets 5f above set temperate it will cool down to 74f
12:05 AM pink_vampire: here it was 122f in the top part of the room
12:06 AM XXCoder: yeech!
12:06 AM CaptHindsight: heh car was 140F today when I got in
12:06 AM XXCoder: open top to let it escape and doors let cooler air in
12:11 AM XXCoder: you could cook cookies in my car if i forget to put in mirrored window insert
12:11 AM pink_vampire: there is nothing to open in the top part :(
12:11 AM XXCoder: it feels like oven door opening when I open doors. not kidding. i had to open all 4 doors everyday
12:11 AM CaptHindsight: I should IR tint my windows
12:11 AM pink_vampire: IR?
12:11 AM CaptHindsight: infra red
12:11 AM XXCoder: interfried. keeps inside cooler
12:11 AM XXCoder: i cant spell worth crap lol
12:11 AM pink_vampire: link
12:11 AM CaptHindsight: look up "hot mirror"
12:11 AM pink_vampire: can i put it on the car?
12:11 AM XXCoder: capt issue is i would need it for maybe 2 months
12:11 AM XXCoder: then rest of year it gets in my way by making stuff dark in night
12:11 AM XXCoder: if I remove and reapply it gets expensive
12:11 AM CaptHindsight: cover car in aluminum foil in summer
12:13 AM pink_vampire: it is 60" by x feet
12:13 AM XXCoder: well yeah
12:13 AM XXCoder: i calculated 4 foot
12:18 AM XXCoder: https://www.ebay.com/itm/VLT75-Car-Window-Tint-Solar-Tint-Film-99-UV-Proof-Automotive-Accessories/153498409587
12:18 AM pink_vampire: is that also IR?
12:18 AM XXCoder: apparently
12:19 AM XXCoder: issue is its from hongkong
12:19 AM XXCoder: by time it arives summer is half over
12:20 AM pink_vampire: I'm only see UV
12:21 AM XXCoder: oh thought it was 99% uv and 75% ir
12:21 AM XXCoder: "VLT75%" no idea
12:22 AM XXCoder: https://www.ebay.com/c/2170783242
12:22 AM XXCoder: very big shipping times lol
12:27 AM pink_vampire: I just try to drive at night
12:27 AM XXCoder: i dont have to try lol
12:28 AM XXCoder: summer or winter end of shift i always drive in very late night
12:29 AM XXCoder: unfortunately I always drive to work in peak day (2 pm)
12:29 AM XXCoder: so its at hottest time of day
01:54 AM pink_vampire: someone here can help me with arduino?
01:54 AM XXCoder: dont know much about that hopefully someone can evenuallly
01:55 AM pink_vampire: I'm trying to make something super simple, set a color to individual leds
01:56 AM XXCoder: cool :) bet its just setting specific pin to certain value
01:56 AM Deejay: moin
01:56 AM XXCoder: but i dont know anymore more specific
01:56 AM XXCoder: hey
01:56 AM Deejay: hey :D
01:58 AM pink_vampire: what 50 mean in the neopixel?
01:58 AM pink_vampire: colorWipe(strip.Color(0, 255, 0), 50); // Green
01:59 AM XXCoder: i need more context. like colorWipe function code
01:59 AM pink_vampire: this is the code
01:59 AM pink_vampire: https://github.com/adafruit/Adafruit_NeoPixel/blob/master/examples/buttoncycler/buttoncycler.ino
01:59 AM pink_vampire: line 62
01:59 AM XXCoder: ok lets see
02:00 AM XXCoder: look at line 95
02:00 AM pink_vampire: void colorWipe(uint32_t color, int wait) {
02:01 AM XXCoder: yep
02:01 AM XXCoder: look at second parameter
02:02 AM pink_vampire: wait??
02:02 AM XXCoder: yeah
02:03 AM XXCoder: looks like it waits 50 milliseconds (millisecond is typical for time
02:03 AM pink_vampire: no idea what it even do
02:04 AM XXCoder: colorwipe function is where it actually changes colors
02:04 AM XXCoder: in it strip.setPixelColor(i, color) sets the color
02:04 AM XXCoder: strip.show() I guess make it actually update and change colors.
02:04 AM XXCoder: delay(wait) is when it just waits for 50 ms
02:05 AM XXCoder: its in a loop so I guess it touches all leds
02:06 AM pink_vampire: I want to set a pattern like LEDs 1-3 will be red, and LEDs 4-6 will be orange, and if I click the button, it will change to to other pattern, like LEDs 1-3 will be green, and LEDs 4-6 will be blue
02:06 AM XXCoder: best way would be create a function for that
02:07 AM pink_vampire: what do you mean?
02:07 AM XXCoder: using strip.setPixelColor(i, color) and strip.show
02:07 AM XXCoder: first variable of that call is which led, second is color
02:08 AM XXCoder: so have 2 functions setRedOrange() and setGreenBlue()
02:08 AM XXCoder: and call first for before press, and button press calls latter
02:10 AM pink_vampire: so I'm trying to edit the case 0
02:10 AM pink_vampire: to be red/orange
02:10 AM pink_vampire: line 56
02:11 AM XXCoder: ya removed the colorWipe function and writing your own?
02:12 AM pink_vampire: something like that
02:12 AM XXCoder: it looks very strightforward
02:12 AM pink_vampire: I'm not sure what I'm doing..
02:12 AM XXCoder: for me programming side is easy, but i know pretty much nothing about aurdino
02:12 AM XXCoder: just was reverse engineering from your exampkle
02:14 AM pink_vampire: this is wayyyyyyyyyy beyond me
02:14 AM XXCoder: nah it arent
02:14 AM XXCoder: you just need some time to walk up learning curve
02:14 AM XXCoder: 'youre quite a bit smarter than me
02:15 AM pink_vampire: XXCoder: not in programming
02:15 AM pink_vampire: it is the most boring task for me
02:15 AM XXCoder: really whats you do to make gcode?
02:16 AM pink_vampire: I can fall a sleep during programming,
02:17 AM pink_vampire: it feel like I just want to be done with it.
02:17 AM XXCoder: lol well what ou want you should be done by now
02:17 AM XXCoder: its not very complex
02:17 AM pink_vampire: what is the syntax for strip.setPixelColor(i, color)
02:17 AM pink_vampire: what is color?
02:18 AM XXCoder: thats data type.
02:18 AM XXCoder: you set it with strip.Color( 0, 0, 0)
02:18 AM pink_vampire: I'm trying
02:18 AM pink_vampire: strip.setPixelColor(1, 128, 128, 0);
02:18 AM XXCoder: no it have to be one object
02:19 AM XXCoder: a second typing exaple
02:19 AM XXCoder: strip.setPixelColor(1, strip.Color( 128, 128, 0))
02:19 AM XXCoder: yes it calls a function inside function
02:20 AM XXCoder: inside function creates a color object for you and you directly send it to setpixelcolor function
02:20 AM pink_vampire: mmmm not sure
02:20 AM XXCoder: no variable needed
02:20 AM pink_vampire: lets see the stuff you did
02:21 AM pink_vampire: it is ignore it
02:21 AM XXCoder: whats source code look like now?
02:22 AM XXCoder: you do have to also do strip.show(); after set that in order to update display
02:22 AM pink_vampire: https://pastebin.com/CNt2dCjR
02:22 AM pink_vampire: I'm trying to edit line 57
02:22 AM XXCoder: add line i just said to line below line 57
02:23 AM pink_vampire: ok
02:23 AM pink_vampire: lets see
02:24 AM pink_vampire: I think it work!
02:24 AM XXCoder: cool :) add some more setpixels before show call
02:25 AM XXCoder: its better design really, you dont want it to change leds as you set values. you want all to change at once.
02:25 AM pink_vampire: now I'm trying to make 2 loops
02:26 AM XXCoder: so basically for ... loop 3 reds, for... loop 3 oranges, then finally strip.show() to show changes
02:26 AM pink_vampire: mm something like that
02:26 AM pink_vampire: I hope
04:02 AM phipli: Morning
04:35 AM XXCoder: pink_vampire: hows programming so far
04:35 AM XXCoder: yo
06:12 AM Tom_L: morning
06:12 AM XXCoder: hey
06:29 AM Tom_L: looks like that code just walks thru the 8 colors and back to black. rinse and repeat
06:29 AM XXCoder: yeah
06:29 AM Tom_L: editing the case statements won't fix that
06:30 AM XXCoder: shes modifing it
06:30 AM XXCoder: didnt you see later version?
06:30 AM Tom_L: nope. just woke up
06:30 AM XXCoder: lol ok
06:34 AM Tom_L: pause between the 2 loops if you want to see the display
06:34 AM XXCoder: its just setting colors
06:34 AM Tom_L: i hate even looking at arduino sloppy code
06:34 AM XXCoder: show at end is what makes leds actuallu change color
06:35 AM Tom_L: is it an led strip?
06:35 AM XXCoder: seems so?
06:36 AM XXCoder: i dont know the physical side
06:36 AM XXCoder: nor arudino really but that code is simple, i just had to do quick steps backwards to figure how it should work
06:36 AM Tom_L: must be something else if the colors can change 8 colors
06:36 AM XXCoder: maybe its addressable strip
06:37 AM XXCoder: i dont know strip.show() actually does at controlling
06:37 AM Tom_L: ok that's my 10 sec of it. i'm done with it
06:37 AM XXCoder: lol ok
06:37 AM XXCoder: i want to do some programming but same problem I have for long while now plagues me
06:38 AM XXCoder: no willpower at all
06:46 AM JT-Mobile: morning
10:44 AM Tom_itx is now known as Tom_L
11:41 AM justan0theruser is now known as justanotheruser
12:39 PM _unreal_: There My A axis is now wired in
12:39 PM _unreal_: Though I see need to tune the the current output. AND enable the thing
12:41 PM _unreal_: you know its kind of funny. this guy does a great job of video editing etc.... BUT he has almost no views https://www.youtube.com/channel/UCiANfkB8tb8V3QnN9zvES6g/videos
12:45 PM gloops: so..now i know why the CNC PC blackscreened
12:45 PM gloops: after much calamity and purchases
12:45 PM gloops: monitor contrast was full down
12:47 PM jym: lol
12:47 PM jym: how did that happen?
12:48 PM perry_j1987: hmm
12:48 PM Tom_L: gloops did you see andy got RTAI working with stretch etc?
12:48 PM perry_j1987: was given a new dehumidifier that doesnt make water
12:48 PM gloops: assuming - piling stuff up around it - button on monitor got pressed
12:48 PM perry_j1987: took the shroud off and only gets marginally cool on the inlet tubing to the condenser
12:49 PM perry_j1987: what would some fun uses be for the compressor
12:49 PM gloops: Tom_L i had a brief look at the link you gave and bookmarked it, not had chance to look at it properly
12:49 PM Tom_L: tested 3 MB with it last night
12:50 PM gloops: now that i have got a spare PC to play with..i might have a go at it sometime
12:51 PM gloops: apparently 2.8 runs best on stretch, but parport works best on RTAI - wheezy
12:51 PM gloops: im using both
12:51 PM Tom_L: https://github.com/andypugh/RTAI/releases
12:52 PM gloops: tbh never had one problem with 2.8 or linuxcnc at all in the time ive used it on wheezy
12:52 PM Tom_L: that's the one you want to try
12:53 PM gloops: ok thanks have saved, my first job tommorrow is putting computer back on cnc machine
12:53 PM andypugh: Tom_L: memfrob did all the hard work.
12:53 PM Tom_L: yes but you put it together for us
12:55 PM Tom_L: i think he was pretty pleased last night
01:08 PM _unreal_: https://pinshape.com/users/169107-sexycyborg#designs-tab-open
01:09 PM _unreal_: I bait clicked the underlit led then checked the profile. Looking over the different designs the tampon magazine got me LOL'ing
01:14 PM andypugh: Naomi is an interesting character, that’s for sure
01:16 PM _unreal_: yep
01:16 PM _unreal_: I'm looking for an STL or gcode file. looking for grapes grape vine/ grape bunch
01:17 PM _unreal_: trying to find a good 3d path. was at my fathers house and he made some horazontal wine bottle holders. and one he made was a "test" one and its lightly beat up. nothing major. but I'm looking at milling a grape bunch and some vines into it to get rid of the chewed up wood area.
01:17 PM andypugh: I thought you were asking for an STL file of Naomi Wu :-)
01:17 PM _unreal_: and he used it to punch some letters
01:18 PM _unreal_: ! I am now
01:18 PM gloops: hmm have a look on wildgoose carvings, i think its them who have a load of 3d stls free to download
01:18 PM _unreal_: wildgoose.com?
01:19 PM andypugh: _unreal_: https://www.myminifactory.com/object/3d-print-3d-body-scan-structured-light-25039
01:19 PM _unreal_: google is being a bitch a bitch and only giving me $$ results
01:20 PM gloops: actually it isnt wildgoose that does the 3 models, one of the american wood carving shops has them online, cant remember the name now
01:21 PM gloops: Ichs gave me the link ages ago, i downloaded some they werent bad, he comes in here as PC1234 kind of nick now
01:22 PM _unreal_: hum
01:22 PM _unreal_: ya that site has nothing
01:22 PM _unreal_: oh not wildgoose heh
01:22 PM _unreal_: andypugh, interesting
01:23 PM andypugh: (I knew it existed because she once sent me the link in response to a Youtube comment about 3D printing clothing)
01:23 PM gloops: sorry for being totally unhelpful lol
01:25 PM _unreal_: I downloaded one from cncart.club but its not exactly what I was looking for
01:26 PM _unreal_: https://cncart.club/cnc-files/download/19-food-designs/78-dowload-free-stl-file-of-grapes-3d-stl-file-for-cnc-woodworking
01:26 PM gloops: https://www.osbornewood.com/CAD-Drawings.aspx?file=8773_3dstl.stl&category=1207&productid=586511
01:27 PM gloops: its osbornewood
01:27 PM gloops: https://www.osbornewood.com/CAD-Drawings.aspx?
01:35 PM gloops: grapes https://www.osbornewood.com/891992.aspx
01:36 PM gloops: https://www.osbornewood.com/7550.aspx
01:43 PM _unreal_: heh $111
01:44 PM gloops: thats for the carving, think the model is there free
01:45 PM gloops: so download the model, get carving and sell them for $110
01:47 PM _unreal_: checking
01:51 PM gloops: i did start drawing some corbels with vectors instead of mesh, much quicker to cut - another project not yet complete heh
01:54 PM _unreal_: https://www.osbornewood.com/7512.aspx?position=48&searchGUID=5e088241-78a5-40a2-bb3b-51db38e737c6&sortOption=Relevance
01:56 PM gloops: yeah the stl model is straight under the image
01:56 PM gloops: size it to what you want, stretch it whatever, you can edit most 3d models in blender
01:59 PM _unreal_: I've never worked with STL files not sure what to use
01:59 PM _unreal_: and i'm on linux
02:03 PM gloops: blendercam will generate gcode for 3d, i can probably sort you out with some other software that will run on wine but another day im just off out
02:16 PM andypugh: _unreal_: How do you normally generate your G-code?
02:29 PM _unreal_: inkscape
02:29 PM _unreal_: but this is a 3D
02:30 PM _unreal_: https://support.bantamtools.com/hc/en-us/articles/115001671634-Converting-STL-Files-to-G-code
02:30 PM _unreal_: trying to follow this BUT the menues are different AND the example is from a mac
02:31 PM andypugh: So, you are using FreeCAD?
02:31 PM andypugh: A reasonable choice, but not one I can help you with.
02:31 PM _unreal_: ok figured that part out.
02:31 PM _unreal_: yes
02:32 PM _unreal_: ARG.... one of my number one complaints is changing menus between versions
02:32 PM _unreal_: such a poor idea for software designers
02:33 PM _unreal_: @#%!#$%@#$ freaking hell it wants me to import to fusion360
02:34 PM _unreal_: wtf
02:39 PM andypugh: That makes no sense.
02:40 PM andypugh: Why not import the STL into Fusion if youa re going to use that?
02:41 PM andypugh: It is possible that the instructions you are following are from before FreeCAD could generate G-code?
02:44 PM _unreal_: I am not planning ot use fusion
02:44 PM _unreal_: thats a windows program
02:44 PM _unreal_: I'd have to reboot into wondows
02:45 PM _unreal_: as I understand it freecad can do tool pathing etc.. I jus dont know how never have used it
02:45 PM Tom_L: andypugh you think your system is corrupt the reason you're having RTAI issues?
02:47 PM andypugh: No idea.
02:47 PM andypugh: I just did a clean build and it still does it.
02:48 PM Tom_L: i'm sure you've already tried shutting off things in the bios?
02:48 PM andypugh: It all works if I pur a symlink in from usr/local/modules to usr/realtime…./modules
02:48 PM andypugh: No, the problem here is only with the RTAI testsuite, and that is that it is looking in the wrong place for the RTAI modules.
02:48 PM Tom_L: i see
02:49 PM andypugh: Not an issue for LinuxCNC
02:49 PM Tom_L: so linuxcnc will load?
02:50 PM Tom_L: my gigabyte mb wouldn't do anything until i fixed the bios
02:50 PM gregcnc: are there other makes of this type of knurling tool? https://www.ebay.de/itm/273464684102
02:51 PM Tom_L: the other 2 were ok
02:52 PM Tom_L: gregcnc, those are probably better than the single bump roller
02:52 PM Tom_L: i can't see from the pic if the head swivels any
02:53 PM Tom_L: some do so they self center
02:53 PM gregcnc: no, it's adjustable for diameter
02:53 PM Tom_L: right but some also swivel
02:53 PM gregcnc: there is no side load on the part
02:53 PM Tom_L: right
02:54 PM gregcnc: those are too big for my lathe
02:54 PM Tom_L: maybe swivel was a bad choice of words
02:54 PM gregcnc: i know the type
02:55 PM Tom_L: https://www.accu-trak.com/holders_bump.html
02:55 PM Tom_L: there's both single and dual roller
02:55 PM gregcnc: not what i need
02:55 PM Tom_L: yeah, just saying
02:56 PM Tom_L: further down shows what i was referring to
02:56 PM gregcnc: yes, I've looked at everythign i could find
02:56 PM Tom_L: what are you looking for?
02:56 PM Tom_L: make one?
02:57 PM gregcnc: even for the 3-400USD they ask, probably not worth it
02:57 PM Tom_L: not unless you're gonna do alot of parts
02:57 PM gregcnc: I mean3-400 is cheap
02:58 PM gregcnc: i haven't seen these though. https://www.accu-trak.com/holders_straddle.html
02:58 PM Tom_L: https://www.ebay.com/itm/NEW-ACCU-TRAK-SINGLE-WHEEL-FIXED-BUMP-TYPE-KNURLING-LATHE-TOOL-HOLDER-OR-BHBPRA/172499837696?hash=item2829caa300:g:n4sAAOSwNnRYiAET
02:58 PM Tom_L: single
02:59 PM Tom_L: but you don't get the diamond knurl with that
02:59 PM Tom_L: https://www.ebay.com/itm/Pivot-Head-Bump-Knurler-Tool-Holder/253551260324?epid=26017804862&hash=item3b08d532a4:g:EAEAAOSwMPxay8lx
02:59 PM Tom_L: hah
03:00 PM gregcnc: 3mm parts?
03:00 PM JT-Mobile: I think I knurled something once
03:00 PM gregcnc: i'm specifically looking for a straddle type
03:00 PM Tom_L: is that what you're trying to knurl?
03:01 PM Tom_L: i used to knurl stuff all the time, and roll threads
03:01 PM Tom_L: similar
03:02 PM gregcnc: BTW you can buy diamond knurl wheels
03:03 PM Tom_L: yeah
03:03 PM Tom_L: the diamond we did were 2 roller
03:03 PM Tom_L: i think they come out better
03:23 PM SpeedEvil: https://www.youtube.com/watch?v=WgsQCtFDY58 What happens when a 20000hp jet engine eats three grams of stainless steel.
03:23 PM SpeedEvil: (LM1600 power turbine)
03:24 PM andypugh: gregcnc: https://www.arceurotrade.co.uk/Catalogue/Cutting-Tools/Knurling-Tools/12mm-Clamp-Type-Knurling-Tool
03:25 PM gregcnc: failry certain that type won't even fit the turret
03:25 PM andypugh: Or this one is direct toolpost mount (but not a straddle type) https://www.arceurotrade.co.uk/Catalogue/Machines-Accessories/Lathe-Accessories/Tool-Posts/Model-000-Knurling-Tool-Holder
03:27 PM andypugh: More options here: https://www.rdgtools.co.uk/acatalog/copy_of_Knurling_Tools.html
03:27 PM gregcnc: the zeus is probably ideal. I mainly wanted to know if there was another source for that type
03:27 PM andypugh: You could change the knob for a screw if that’s the problem.
03:29 PM andypugh: You could buy ten of the others and weld them together for the price of the Zeuss.
03:29 PM * SpeedEvil wonders if 'knurl that with this file' was a common task for apprentices.
03:30 PM gregcnc: shit tools are still such
03:30 PM andypugh: I have certainly knurled things with a file. It was a part of the apparatus for my PhD project though.
03:31 PM gregcnc: unfortunately to fit my little CNC is needs to be compact and i want something decent, that will do small parts
03:31 PM gregcnc: some of the Swiss specific knurls could work, but have limited range which isn't surprising
03:36 PM gregcnc: I don't understand metal working tooling. I've now seen the exact same knurl tools as the Accutrak on 4 different company sites. This is quite common.
03:39 PM perry_j1987: hmm that didnt work quite like i thought
03:39 PM perry_j1987: i had an old pancake air compressor cheapie that gave up the ghost but i've kept it around
03:39 PM perry_j1987: i just disconnected the compressor unit from the tank and aded an air fitting
03:39 PM perry_j1987: so i can basically use it as additional tank capacity and a regulator right at the cnc
03:40 PM perry_j1987: but its got this horrible whistle pitch when its filling up and also emptying(being used)
03:41 PM SpeedEvil: Is the whistle internal or nozzle related?
03:52 PM Deejay: gn8
04:12 PM perry_j1987: internal
04:14 PM Tom_L: gregcnc, what cnc do you have?
04:15 PM gregcnc: Emco 325-II
04:16 PM Tom_L: nice little lathe
04:17 PM _unreal_: Tom_L, do you need to reporgram the bios?
04:17 PM _unreal_: as in badflash?
04:17 PM gregcnc: it has it's quirks
04:17 PM Tom_L: _unreal_ rather random question. what are you talking about
04:17 PM _unreal_: ARG.... I'm just trying now to figure out how to turn this stl into a tool path
04:18 PM _unreal_: <Tom_L> my gigabyte mb wouldn't do anything until i fixed the bios
04:19 PM Tom_L: turned off hyperthreading and any treehugger green settings
04:24 PM _unreal_: You bastard your the one who killed the red wood forest
05:25 PM perry_j1987: well there we go got a regulator mounted on the cnc cart and the mist coolant setup installed
05:29 PM gloops: onwards and upwards
05:30 PM gloops: this week ill mainly be making beehives
05:30 PM _unreal_: perry_j1987, sweet
05:30 PM _unreal_: perry_j1987, I got my A axis connector setup
05:31 PM perry_j1987: nice i love my 4th axis
05:31 PM _unreal_: still have to deal with tuning the current etc.. but I have not even enabled the damn thing
05:31 PM perry_j1987: i got a belt drive hollow shaft 4th axis
05:31 PM perry_j1987: can fit 22mm rod through the 4th axis
05:31 PM _unreal_: I have two issues with the A axis. one its just about to tall for my cnc
05:31 PM _unreal_: and I dont have any kind of a chuck system for it
05:32 PM perry_j1987: do you have a hollow spindle on yours?
05:32 PM _unreal_: perry_j1987, https://photos.google.com/share/AF1QipO3nGHag8ELYJ55Z0LCBpYJsggvayqEC_D7fRpKxO8z6HE81h-jcGWWevfc2qh8rg/photo/AF1QipN_2hN7j-WRw_1xXPimorSeofAjtA4Xbz4gzNCj?key=eDgzcXhFLVR1czMzbmtfaDVOMElyc3FydTA1SWpR
05:32 PM _unreal_: see if that link works
05:32 PM _unreal_: bottom right you can see my A axis
05:32 PM _unreal_: Thats a photo from like 8 years ago
05:33 PM perry_j1987: ah like little worm gear box eh
05:33 PM _unreal_: ya
05:33 PM _unreal_: that WAS a worm drive driving a pully system to some laser something or other system
05:33 PM perry_j1987: you can get cheap 2 or 3 inch chucks on ali
05:33 PM _unreal_: that I pulled years ago
05:33 PM _unreal_: it has like 1 degree play in it BUT that thing is freaking 120:1
05:33 PM perry_j1987: mine is 6:1 belt drive
05:33 PM _unreal_: as I recal
05:34 PM _unreal_: the shank is 1/4"
05:34 PM _unreal_: and double sided
05:34 PM perry_j1987: what are the bearings in it
05:34 PM _unreal_: ?
05:34 PM _unreal_: I'm not sure wha tyour asking
05:34 PM _unreal_: it has bearings :)
05:34 PM gloops: for wood youd probable get away with a wood lathe drive centre and some simple screw on the tailstock to tighten in, would say a dead centre would work - a sharpened threaded bar maybe
05:35 PM perry_j1987: err i mean can you press that tiny shaft out and put somethin bigger in
05:35 PM gloops: you are going to be throwing 12 inch
05:35 PM gloops: arent
05:35 PM _unreal_: perry_j1987, no
05:35 PM perry_j1987: well if you can press it out you could make a new custom spindle with faceplate for a small chuck
05:36 PM perry_j1987: or one of those real small chucks that thread on
05:36 PM _unreal_: I'm just going to get a small chuck
05:36 PM _unreal_: they are out there
05:36 PM _unreal_: one side has a 4" shaft sticking out. the other side is like 3/4
05:36 PM _unreal_: I'll likely put a small chuck on the short side
05:37 PM _unreal_: not sure what to do with the long side. I use to have to of them but someone purchased the other off of me for like $80 18 years ago
05:38 PM _unreal_: as I recall that part was a $400+ item for some laser image printer.
05:38 PM _unreal_: it had some DC high power high speed with encoder motor on it but I took it off long ago
05:38 PM _unreal_: :( long gone
05:44 PM perry_j1987: can always throw a jacobs chuck on it
05:44 PM perry_j1987: heh
05:44 PM gloops: or look out for a scrap cheap wood lathe, all the bits you need there, i got some parts off the car boot sale - mt1 tailstock etc for pennies, decided to make a dedicated cnc wood lathe though based on a full manual lathe
05:45 PM gloops: (as opposed to adding 4th to router)
05:46 PM perry_j1987: what do you do with wood and 4th axis
05:48 PM gloops: i havent built mine yet, but mainly carved spindles
05:49 PM perry_j1987: selling harry potter wands on etsy ? :P
05:51 PM _unreal_: this is really pissing me off
05:51 PM _unreal_: all I want to do is convert that grape cad file into a tool path
05:51 PM _unreal_: GOD I wish i could remember the name of the tools I use to use. it was SOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO easy before
05:52 PM _unreal_: people have really gotten stupid software coding and making way to hard and non standard methods of software work flow design
05:52 PM Tom_L: grape cad file?
05:52 PM Tom_L: flavored?
05:53 PM Tom_L: tried inkscape?
05:55 PM _unreal_: https://www.osbornewood.com/7512.aspx?position=48&searchGUID=5e088241-78a5-40a2-bb3b-51db38e737c6&sortOption=Relevance
05:55 PM _unreal_: tom
05:56 PM _unreal_: I just need/want to turn that into a tooling path. scale it down to about a 1" item and mill it into the wood I have
05:56 PM gloops: you cant sell with the Harry Potter logo theyre all over it
05:56 PM Tom_L: none of those drawings appear to be 'good' 3d convertable
05:57 PM gloops: you can make stuff like this though https://www.youtube.com/watch?v=0J9hEr4eAFY
05:57 PM Tom_L: don't even know what 3d mesh dxf is
05:57 PM Tom_L: dxf is 2d
05:58 PM gloops: the stl and dxf will open in blender
05:58 PM Tom_L: stl sucks
06:00 PM gloops: its not great for editing, but it works fine for wood carving, i can get decent toolpaths from the files on osborne
06:00 PM _unreal_: HAY. if your going to fight take it out side :)
06:00 PM _unreal_: osborne?
06:00 PM _unreal_: gloops, oh that site
06:00 PM gloops: yeah osbornewood
06:01 PM _unreal_: and regardless I'm looking to scale the design down to 1"
06:01 PM _unreal_: :)
06:01 PM Tom_L: no detail left
06:03 PM Tom_L: appears 3dmesh dxf is a proprietary format
06:03 PM gloops: your going to need tiny ballnoses and v bits to keep the form of that
06:03 PM gloops: at 1 inch
06:03 PM _unreal_: which I have
06:04 PM Valen: ey andypugh hows things
06:04 PM Tom_L: yeah otherwise just carve something that looks like the shape of africa and be done
06:05 PM andypugh: Valen: I am finding myself lost in DH parameters.
06:05 PM andypugh: I have some Arduino code, and I have a Faro arm, but I don’t know which of several possible DH conventions the code uses. Or, for that matter, if it actually works.
06:07 PM perry_j1987: hey guys i got a dehumidifier here that the coolant leaked out so its not working. trying to come up with a use for the compressor on it
06:07 PM Valen: that sounds like far too much complex maths for me andypugh ;-)
06:08 PM andypugh: Me too. It uses vectors, lots of them.
06:08 PM skunkworks: perry_j1987: a crapy vacumm pump?
06:08 PM * Valen was reading scrollback rtai release hmm might have to give that a go for the hell of it ;-)
06:09 PM perry_j1987: skunkworks i have two vacuum pumps already
06:09 PM Valen: think it'd work on buster?
06:09 PM Tom_L: it should
06:09 PM Valen: (have preempt working now)
06:09 PM Tom_L: give it a go
06:09 PM perry_j1987: maybe make a quiet air compressor with this old pancake air compressor i have that gave up the ghost
06:09 PM * Valen puts it on the list
06:09 PM gloops: the bloke who made this has been in here, also on facebook occassionally https://i.pinimg.com/originals/f3/37/5b/f3375b993181c795c4ea2dd7da0ec178.jpg
06:09 PM Tom_L: you may have to remove a couple things you've installed
06:10 PM perry_j1987: wow gloops
06:10 PM gloops: yuri..err something or other
06:10 PM Valen: did it run in place no linuxcnc packages for buster, I'll just make another copy
06:11 PM _unreal_: gloops, wonder if I can build this for fedora https://github.com/FernV/NativeCAM
06:11 PM Tom_L: Valen, the more tests the better
06:12 PM _unreal_: perry_j1987, what is the issue with the dehumidifier
06:12 PM gloops: hmm, Ichs would probably help with that _unreal_ he did some tutorials on nativecam with linuxcnc
06:13 PM _unreal_: if it is low on freon. depends on how the system is designed. charging it again is not hard
06:13 PM perry_j1987: it appers to have lost coolant
06:13 PM perry_j1987: compressor kicks on fan works but doesnt get quite cold
06:13 PM Valen: low gas or shagged motor, one often leads to the other
06:13 PM _unreal_: ok so its likely got a leak
06:13 PM perry_j1987: the inlet tubing to the coils gets slightly cool but overall everything stays pretty room temperature
06:13 PM Valen: s/motor/compressor
06:13 PM perry_j1987: so low coolant
06:14 PM _unreal_: if so then its not going to have the pressure to work the pressure switch.
06:14 PM Valen: if you want the thing getting a guy out to leak test and refill it may not be silly?
06:14 PM _unreal_: perry_j1987, there is an internal pressure switch that if it does not have enough gas. it cant build the pressure on the high side and wont operate
06:15 PM _unreal_: putting leak test etc... works but the unit may be cheaper to purchase a new one then to fix it
06:15 PM _unreal_: perry_j1987, I did a lot of AC work on yachts
06:15 PM _unreal_: A LOT!!!!
06:15 PM perry_j1987: i dont think they make these dehumidifiers serviceable ie crimped off tubing etc
06:16 PM perry_j1987: i dont need the thing someone just gave it to me so im looking for excuse to tear it apart heh
06:16 PM XXCoder: wonder if your machine is low on working fluid
06:17 PM _unreal_: when you charge an AC system with 18 lbs of of r407
06:17 PM XXCoder: _unreal_: less and less machines use freon
06:17 PM _unreal_: thats a BIG ass compressor setup
06:17 PM XXCoder: its hazard to ozine
06:17 PM _unreal_: XXCoder, LOL!!!!!!!!!
06:17 PM _unreal_: worng
06:18 PM _unreal_: What is one of the major ingredients that is also used in pools
06:18 PM XXCoder: what you dumb?
06:18 PM Tom_L: water?
06:18 PM _unreal_: nope
06:18 PM XXCoder: freon is a CFC and bad for ozone.
06:18 PM _unreal_: palm to face
06:19 PM _unreal_: omg..
06:19 PM _unreal_: ok
06:19 PM _unreal_: simple answer
06:19 PM _unreal_: some pool addatives are the same as what is in freon.
06:19 PM _unreal_: ok
06:20 PM XXCoder: another fucking racist fuckhead police. https://worldnewsdailyreport.com/kentucky-police-shoot-white-coal-miner-5-times-thinking-he-was-black/
06:21 PM _unreal_: XXCoder, if you believe all freon is bad for the environment your a fool falling for the tree hugging liers BS.
06:21 PM XXCoder: "your"
06:21 PM XXCoder: "liers" lol
06:21 PM XXCoder: its proven fact that freon damages ozone layer.
06:22 PM _unreal_: Chlorine is NOT in R22 considered to be the best refrigerent gas EVER
06:22 PM XXCoder: i dont fucking follow hippies or hipsters for science stuff
06:22 PM _unreal_: low energy low pressure
06:22 PM _unreal_: and the list goes on and it lasts for ever
06:22 PM _unreal_: now enter r134A and many others. they are designed with obsolesence
06:22 PM XXCoder: so ac uses freon thats chemically different, and does not react with ozone?
06:23 PM Tom_L: supposedly
06:23 PM _unreal_: XXCoder, look up r22
06:23 PM Tom_L: only time will really tell the effects of anything we as humans do
06:23 PM _unreal_: that is a NON Chlorine
06:23 PM XXCoder: okay now thats far better than blunt and unexplained "Wrong!"
06:24 PM _unreal_: XXCoder, the amount of OZONE killing Chlorine
06:24 PM SpeedEvil: R22 has chlorine in it.
06:24 PM SpeedEvil: https://en.wikipedia.org/wiki/List_of_refrigerants
06:24 PM SpeedEvil: https://en.wikipedia.org/wiki/Chlorodifluoromethane
06:24 PM SpeedEvil: The chloro at the start is a hint.
06:24 PM _unreal_: r410 sorry your right
06:24 PM Tom_L: runs at a higher pressure too
06:25 PM XXCoder: got curious on what mine uses
06:25 PM gloops: could be a chinese myth you know
06:25 PM _unreal_: r22 runs at a lower pressure then r134a
06:25 PM Tom_L: and 410
06:26 PM SpeedEvil: Bring back R717
06:26 PM XXCoder: R-410A
06:26 PM _unreal_: regardless the amount of Chlorine that will escape any AC or chiller etc.. system is a fraction to what pools put into the air
06:26 PM _unreal_: OZNE
06:26 PM _unreal_: ozone
06:27 PM _unreal_: That is where my WORNG comes from
06:27 PM Tom_L: there used to be a log of who spoke and how often here i believe. it would be interesting to see a log of all the topics we cover here
06:27 PM SpeedEvil: _unreal_: chlorine and chlorinated carbon compounds behave very, very differently in the atmosphere.
06:28 PM _unreal_: SpeedEvil, very true
06:28 PM XXCoder: does one from pool affect ozone?
06:28 PM _unreal_: rate of impact for starters
06:29 PM SpeedEvil: XXCoder: no, it gets rained out, basically after being converted to HCl mainly
06:29 PM XXCoder: found this. interesting https://aquamagazine.com/service/ozone-and-uv-systems-allow-pool-owners-to-approach-no-chlorine-systems.html
06:30 PM XXCoder: uses ozone directly and UV to clean pool water
06:30 PM pcw_home: Yep, Chlorine doesn't makes it to the Ozone layer (but CFCs do)
06:31 PM pcw_home: (CFCs do and break down there)
06:31 PM Valen: it's the UV up there that breaks the CFC into C and FC
06:31 PM CaptHindsight: I fly my chlorine up to the ozone layer using old surplus weather balloons
06:31 PM Valen: chlorine at ground level is going to become something other than chlorine a few seconds after it's released
06:32 PM CaptHindsight: i want to hear more anti-science from this guy about CFC's
06:33 PM CaptHindsight: the logic fascinates and humors me
06:33 PM CaptHindsight: it's usually something macho
06:34 PM SpeedEvil: Valen: it's not seconds unfortunately. (I want to try electrolysing large quantities of salt)
06:34 PM SpeedEvil: But it's nowhere near as slow as would let it get to the upper atmosphere.
06:35 PM Valen: ok, presuming you are releasing only enough that you don't need to be somewhere very much else ;-)
06:36 PM pcw_home: Worst mistake I ever made in science class has making Bromine...
06:36 PM SpeedEvil: A kilo or several a day.
06:36 PM XXCoder: once made seriously toxic gas by mistake in my home lol
06:37 PM pcw_home: enough to drive everyone from the room
06:37 PM Valen: why would you want that much straight chlorine SpeedEvil?
06:37 PM pcw_home: (= not much)
06:37 PM XXCoder: take note: water trap can contain ammonia after emptying ammonia water
06:38 PM pcw_home: ah yes, forgotten but not gone...
06:38 PM Valen: till you add the bleach?
06:38 PM XXCoder: yep
06:38 PM XXCoder: i was cleaning house
06:38 PM XXCoder: was cleaning floor then other stuff using bleach]
06:39 PM XXCoder: emptied it, got dizzy lol
06:39 PM XXCoder: opened everything and used fans. it was winter
06:39 PM XXCoder: also constant drain of water to flush
06:39 PM * Valen doesn't really use ammonia for anything
06:40 PM XXCoder: whats you use to mop floor?
06:40 PM Valen: water + soap
06:42 PM XXCoder: well that works I guess, but wont that build up soap slowly?
06:42 PM andypugh: pcw_home: Bromine isn’t very nice. I used it a lot when working as a metalurgist.
06:43 PM Valen: doesn't seem to?
06:43 PM XXCoder: interesting
06:43 PM Valen: only need a nothing of soap to do the work
06:43 PM XXCoder: just curious why you dont like ammonia
06:43 PM pcw_home: Yeah it was nasty, don't know if its worse than Chlorine, but I breathed enough to never want to be near it again
06:43 PM Valen: use disinfectant sometimes, dogs make a mess :-(
06:43 PM andypugh: Bromine/Methanol is a commin etchant. Normally kept very cold with a bit of liquid nitrogen on top.
06:45 PM andypugh: The smell of ammonia always makes me think of cleanliness. I think because my grandmother always used to mop the floors with it
06:45 PM pcw_home: Ahh interesting, but it will warm up eventually...
06:45 PM Valen: I really hate the smell of ammonia lol
06:45 PM pcw_home: I dont think I have any ammonia except in Windex
06:45 PM Valen: https://www.woolworths.com.au/shop/productdetails/1846/pine-o-cleen-disinfectant-pine is my "smell of clean"
06:45 PM andypugh: pcw_home: Well, it’s also dissolved in methanol, and in a fume hood.
06:46 PM XXCoder: for me theres no such thing as "smell of clean" so i just look for how effective more than smells.
06:46 PM andypugh: Anyway, time I was asleep, I have work in the morning
06:46 PM Valen: it's a lizard brain thing. what your mother used to clean
06:47 PM perry_j1987: oh man just got stuck on youtube for long while. bunch of guys making parts for project egress
06:47 PM Valen: that' sorta sprang outta nowhere didn't it perry_j1987
06:47 PM XXCoder: perry got stuck on youtube warped space
06:48 PM perry_j1987: ya i didnt see anything about it and now oxtools, tot and bunch of others have videos up
06:48 PM pcw_home: Yeah a fume hood would be the reasonable thing, not a condenser dripping into an open beaker in a classroom that I stupidly used
06:49 PM perry_j1987: these guys have alot of fun toys
06:49 PM XXCoder: wow! avast told friend of mine that they have credit card info and will auto charge
06:49 PM XXCoder: thing is credit # was never given to avast ever
06:50 PM XXCoder: wonder what happened, avast was decent
06:52 PM Valen: application whitelisting and microsoft AV for me for many years
06:52 PM XXCoder: avast is new AOL
06:54 PM CaptHindsight: i haven't had my win7 machine connected to a network in years
06:56 PM CaptHindsight: can you catch bed wetters by soaking the mattress in bleach?
06:56 PM CaptHindsight: urea + chlorine
06:56 PM XXCoder: well death is kinda harash punishment..
06:57 PM CaptHindsight: catch not punish
06:58 PM CaptHindsight: https://cen.acs.org/articles/94/i31/chemical-reactions-taking-place-swimming.html
06:59 PM * Valen makes a note not to sleep at CaptHindsight's place.
06:59 PM * Valen isn't going to wet the bed, but also doesn't want to sleep on a bleach soaked mattress
06:59 PM XXCoder: lol
06:59 PM CaptHindsight: yeah, difficult to disguise
07:00 PM Valen: CaptHindsight has a thing for blondes i guess ;-)
07:01 PM CaptHindsight: https://en.wikipedia.org/wiki/Urine-indicator_dye
07:02 PM Tom_L: wow, all the way from a bad dehumidifier to peeing in CaptHindsight's pool...
07:02 PM Valen: Tom_L: *bed
07:02 PM Tom_L: sry
07:02 PM Valen: ;-)
07:03 PM CaptHindsight: pool/mattress
07:03 PM XXCoder: i need to try using my ac as working dehumidifier now that I know proper configation of hoses.
07:03 PM CaptHindsight: that is the wonder of science
07:03 PM Tom_L: i've had one running since thur am
07:04 PM CaptHindsight: the connections between science facts and applications
07:04 PM Tom_L: along with 8 air movers
07:04 PM Tom_L: i think they're trying to reenact wizzard of oz in my basement :)
07:04 PM CaptHindsight: vs anti-science opinions
07:06 PM CaptHindsight: XXCoder: how many BTU's per cu ft do you guesstimate for cooling in your area?
07:07 PM XXCoder: i didnt guess, i just looked at room rating
07:07 PM XXCoder: rom it could cool is larger than my room so its fine
07:07 PM XXCoder: my ac is 12000btu
07:08 PM XXCoder: whynter elite arc-122dhp
07:09 PM CaptHindsight: i bought Chinese overstock ductless systems
07:09 PM XXCoder: we plan to put those in
07:09 PM XXCoder: too many irons in fire to do that yet
07:09 PM CaptHindsight: 36K and 48K units
07:12 PM CaptHindsight: was under $2k for 2 heat/cool pumps and 4 indoor units
07:12 PM XXCoder: not bad!
07:12 PM XXCoder: brb
07:15 PM CaptHindsight: they are all I see in Asia
07:15 PM CaptHindsight: Valen: do they mostly use mini-splits there?
07:15 PM Valen: we have ducted now
07:15 PM Valen: depends on the person and the house.
07:16 PM CaptHindsight: window AC's are what i only see in the USA
07:16 PM Valen: people used to have those, everybody is retrofitting with ducted or splits
07:16 PM Valen: multisplit isn't very common
07:16 PM CaptHindsight: new construction here is all ducted central AC
07:17 PM Valen: kinda wished I'd done that though, would mean less energy use at night just running the bedroom, ducted system pushes too much air really for the one room
07:17 PM CaptHindsight: mini's/ductless still aren't common here
07:17 PM CaptHindsight: do you have it zones with dampers for each room/area?
07:17 PM CaptHindsight: zones/zoned
07:18 PM Valen: one zone for Br1, one for Br2 and one for the rest of the house
07:18 PM CaptHindsight: zoning here was always for high end homes
07:18 PM Valen: at night (winter here) we set it to 17C at the pickup and run just the BR1
07:19 PM CaptHindsight: i only use them for cooling
07:19 PM Valen: I need to get under the house and put insulation and an air barrier in to really do the job though, the floorboards are crap and let the wind through lol
07:19 PM CaptHindsight: huh
07:19 PM CaptHindsight: we get so cold here we have basements, frost line is ~40 inches (1m)
07:20 PM CaptHindsight: back to LCNC
07:20 PM Valen: temperature in my bedroom since midnight today https://i.imgur.com/lXMlDxG.png
07:21 PM CaptHindsight: I'm working on getting LCNC to handle DLP/LCD resin printing
07:21 PM Valen: at about 9 I turned the bedroom off and the rest of the house on and set the temperature to 21C when the solar panels were making enough to run the air conditioner ;-)
07:21 PM CaptHindsight: nice range
07:21 PM Valen: the sensor is on my bedside table pretty much in the direct blast of the AC lol
07:22 PM CaptHindsight: was down to 24C this morning in here, was just 28C a few hours ago
07:22 PM Valen: 3Kw of load, about 11Kw of heat pumped
07:22 PM CaptHindsight: only have half the AC in
07:23 PM Valen: hits ~50C here in summer sometimes, needed to get a special AC rated for it lol
07:23 PM CaptHindsight: only 30C here s far, maybe 35C by next weekend
07:23 PM CaptHindsight: 40C is a few times a decade kind of thing
07:24 PM Valen: I'm going to cut a doggy door in the door to the kitchen we never use and close that off as well so the AC will only be heating the bedroom and hallway
07:24 PM CaptHindsight: do you ever get below 0C?
07:24 PM Valen: (gotta go through the kitchen to get outside)
07:25 PM Valen: yeah a few times it'll get to like -4 or something in the mornings
07:25 PM CaptHindsight: we hit -32C last winter for a few days
07:25 PM Valen: that can go jump
07:26 PM CaptHindsight: we get about 2 weeks a year where it's sunny dry and 20C
07:27 PM CaptHindsight: I'm syncing M-codes to SVG images/layers
07:27 PM Valen: solar output is picking up again a bit
07:27 PM CaptHindsight: the g-code for resin SLA/ DLP printers is easy
07:27 PM Valen: summer https://i.imgur.com/3knVRsd.png few weeks ago https://i.imgur.com/KZR8zNb.png
07:27 PM Valen: starting to hit 5Kw again now
07:28 PM CaptHindsight: galvo SLA is also easy, it's like a magic light for a spindle on a very fast XY
07:28 PM CaptHindsight: but DLP/LCD is mostly g-code for Z motions...
07:29 PM CaptHindsight: but you have to sync the correct image to the Z
07:29 PM CaptHindsight: you might also have a wiper and heaters to control/monitor
07:30 PM Valen: bedroom temps since january https://i.imgur.com/ZFBfCYc.png
07:30 PM CaptHindsight: https://www.youtube.com/watch?v=FscYq5uCys0 andy used another method to sync images for layers with Z position
07:31 PM Valen: you can see when the AC went in lol
07:31 PM Valen: well AC and about R4.5 of wall insulation
07:33 PM CaptHindsight: Valen: did you blow insulation into the walls?
07:33 PM Valen: stripped all the asbestos off the outside and put sound/thermal insulation in before recladding
07:34 PM CaptHindsight: older home? pre-1950's?
07:34 PM Valen: 70's we think
07:34 PM Valen: 60's perhaps

07:46 PM CaptHindsight: https://i.imgur.com/QoVC0eR.jpg 300mm wide Z positioner
07:51 PM CaptHindsight: still have to change spindle bearings
07:52 PM XXCoder: wow. police arrested with 52 charges
07:52 PM XXCoder: he was randomly finding meth in cars he stopped
07:52 PM XXCoder: nobody could find a pattern on why he did it
07:53 PM CaptHindsight: and private collecting?
07:53 PM XXCoder: collecting what?
07:53 PM CaptHindsight: the3 meth
07:53 PM XXCoder: no thats the point
07:53 PM XXCoder: people didnt have any meth
07:53 PM XXCoder: he was one who "found" meth in cars
07:53 PM CaptHindsight: oh, please clarify the headline :)
07:53 PM XXCoder: it wasnt even racist thing, he was completely random
07:54 PM XXCoder: hurt a lot of people :( some people lost kids due to this
07:55 PM CaptHindsight: what is worse, preventing medical tech from saving lives or locking up recreational drug users?
07:55 PM XXCoder: huh
07:56 PM XXCoder: im talking bout ethitical police work vs thug police
07:56 PM CaptHindsight: question on morality
07:56 PM CaptHindsight: yes, i understand
07:56 PM gregcnc: what makes more money?
07:57 PM XXCoder: it also hurts his actually legimate cases standings too. which means real criminals could go free too.
07:57 PM XXCoder: its lot of crap all around when one or more cops go bad
07:59 PM CaptHindsight: gregcnc: was out by Dean St earlier, shiny new chain blocking the side road where that child was buried
08:00 PM XXCoder: ??
08:00 PM gregcnc: we drove by the area of the house, but i could tell if people were on that lawn or not
08:01 PM CaptHindsight: XXCoder: local child murder
08:01 PM gregcnc: during the parade
08:01 PM XXCoder: wow that sucks :(
08:01 PM CaptHindsight: XXCoder: parent tried to pass it off as a kidnapping
08:01 PM CaptHindsight: was on national news

08:02 PM CaptHindsight: XXCoder: was mental health issues
08:03 PM XXCoder: makes sense I guess. sucks tho
08:03 PM CaptHindsight: treatment is so poor in this country, so behind as far a science goes
08:03 PM XXCoder: need to get rid of sigma on mental illness also.
08:04 PM CaptHindsight: XXCoder: the mom needed help, was one of those hoarder type homes where she never left
08:04 PM CaptHindsight: the problem now is even if you want help the help is so poor
08:04 PM XXCoder: and so expensive
08:04 PM CaptHindsight: even if you're quite wealthy
08:05 PM XXCoder: bro was heading towards working in pschology. way not enough deaf ones
08:05 PM gregcnc: is mental health included in health care in Europe?
08:05 PM XXCoder: but he saw how shit whole thing was, so he changed tack to public service, DVR specifically
08:06 PM CaptHindsight: gregcnc: yes, part of the national system
08:06 PM gregcnc: ok that's what I was wondering
08:07 PM XXCoder: dvr is quite underfunded unfortunately
08:07 PM XXCoder: expecially recent
08:07 PM gregcnc: that guy that killed the chinese student was in treatment
08:07 PM CaptHindsight: XXCoder: well they are looked at like they did in germany in the 30's
08:07 PM CaptHindsight: waste of life, human sludge
08:08 PM CaptHindsight: if you're not making someone money you are no value
08:08 PM CaptHindsight: of no value
08:15 PM XXCoder: i have met so many people in my life
08:15 PM XXCoder: rich tend to be... boring
08:16 PM XXCoder: expecially ones who talk about their stuff all time
08:16 PM XXCoder: "oh my ferrani have tiny strach damn 100 slaves should die"
08:16 PM XXCoder: well not that extreme but
08:16 PM gregcnc: all kinds of people are boring. how many people really get a chance to do anything intertesting?
08:17 PM gregcnc: then anything another person might find interesting
08:17 PM XXCoder: virtually everyone I have met have done bunch of interesting stuff
08:17 PM XXCoder: rich trends to not have done anything but not always
08:17 PM CaptHindsight: https://www.youtube.com/watch?v=huOBOkN8jVA XXCoder like this?
08:18 PM XXCoder: theres few poor that have done nothing
08:18 PM XXCoder: but those is exceptions
08:18 PM XXCoder: not captioned unfortunately.
08:19 PM CaptHindsight: I'll see if there is one captioned
08:20 PM CaptHindsight: https://www.youtube.com/watch?v=h76RntKeWu0
08:20 PM gregcnc: i don't think i've ever seen that
08:20 PM CaptHindsight: great film

08:49 PM XXCoder: probably 5 digits
08:50 PM XXCoder: nah high 4 digits more likely lol
08:50 PM jym: tire making and axle friction welding... https://www.youtube.com/watch?v=za_1n_drUyM
08:51 PM XXCoder: peetty cool video
08:52 PM XXCoder: nice!

09:07 PM CaptHindsight: what is the difference in deflection between a 1" sq solid 6061 and a sq 1" tube with 1/8" wall?
09:08 PM CaptHindsight: https://www.engineering.com/calculators/beams.htm
09:09 PM CaptHindsight: with 50 lb force 48 vs 33 thou
09:11 PM CaptHindsight: steel is much closer
09:11 PM CaptHindsight: 0.017 vs 0.012

09:32 PM CaptHindsight: Rab: ~6"
09:33 PM CaptHindsight: my first figures were at 12"
09:33 PM CaptHindsight: why you don't see long spans of 1" tube or solids
