12:46 AM fragalot: hi
01:05 AM CaptHindsight: https://imgur.com/gallery/5bsH8 still gives me nightmares
01:09 AM fragalot: xD
01:09 AM fragalot: CaptHindsight: what you didn't know is that that thing is electric
01:09 AM CaptHindsight: Hawking dies aged 76
01:10 AM fragalot: that man must have lived a rough life
01:15 AM fragalot: today I learned that the samsung powerbot things really don't like bower & wilkins
01:15 AM fragalot: either that, or their laser scanner doesn't work on black :P
01:17 AM problems: hi guys. im currently trying to fix up a linuxcnc setup with mesa 6i25+7i76 with DM542T drivers from stepperonline-omc. i have plugged in all cards, connected all wires and installed linuxcnc. i have also followed some dude's step length and direction timing but all my 3 stepper motors are not moving
01:18 AM problems: could it be the 6i25 is not configured properly to run as a 5i25? or step timings are not correct?
01:19 AM problems: how i can tell if my 6i25 is configured properly to run on linuxcnc?
01:19 AM fragalot: pcw_mesa: you in?
01:20 AM CaptHindsight: probably not for 8+ hours
01:20 AM fragalot: was worth the shot :/
01:21 AM fragalot: shame he's not nocturnal like you :P
01:26 AM CaptHindsight: well the blood and the sun and all
01:28 AM CaptHindsight: problems: do you have a scope or meter to check signals?
01:29 AM CaptHindsight: problems: everything wired correctly? All the proper LED's on with the 7i78?
01:30 AM CaptHindsight: https://forum.linuxcnc.org/49-basic-configuration/33507-stepper-does-not-turn-on-mesa-6i25-with-7i76-and-leadshine-m542t
01:39 AM gloops: hawking did push the bar a little higher no doubt
01:41 AM gloops: he wasnt an Isaac Newton though
01:41 AM Loetmichel: gloops: A LITTLE?
01:43 AM gloops: yes he did Loetmichel, he did become THE popular physicist though later on though, that might have exaggerated his contribution
01:43 AM Loetmichel: that was one of the greatest minds we ever had. Newton... phish. The laws that guy found were (while the foundation of anything mechanic) pretty easy stuff. The things Hawking thought up are understood by maybe a few hundred others
01:43 AM fragalot: Loetmichel: 'easy stuff' is relative though
01:43 AM fragalot: both were the first to discover something new
01:44 AM gloops: its all easy when you understand it
01:44 AM fragalot: who knows, in 400 years hawkins radiation might be kindergarten level stuff
01:44 AM fragalot: s/s/g/
01:45 AM fragalot: I have deep respect for either one, but I also don't think that we should compare them
01:45 AM fragalot: both are pioneers, both helped advance science, both deserve respect
01:45 AM miss0r: mornings
01:45 AM gloops: both were ultimately wrong
01:48 AM fragalot: mornin' miss0r
01:48 AM miss0r: fragalot: some pre work IRC, aye?
01:48 AM fragalot: miss0r: Aye.
01:48 AM miss0r: Tell me, what time do you clock in?
01:48 AM fragalot: gloops: Welcome to science.
01:48 AM fragalot: miss0r: typically around 9, clock out around 17:30 / 18:00
01:48 AM miss0r: damn
01:48 AM miss0r: I've always had a 7-15:00 job, I couldn't imagine getting off work later than that
01:48 AM miss0r: unless ofcourse we are talking overtime
01:48 AM Loetmichel: fragalot: what i meant is that while newtons discovery was groundbreaking the things he found were pretty basic. The stuff Hawking did was so complex that it isnt that well understood NOW.
01:50 AM fragalot: that just means he did a good job :P
01:50 AM gloops: yes but hawkings work is easy enough to understand in its popularised form, like in 'a brief history of time'
01:50 AM gloops: similar to Dawkins work with genes
01:50 AM gloops: 'the selfish gene'
01:50 AM Loetmichel: whoever that is
01:51 AM gloops: richard dawkins?
01:51 AM Loetmichel: never heard of
01:51 AM gloops: pretty surprised he gets a lot of coverage
01:51 AM fragalot: in the UK
01:52 AM IchGucksLive: morning from germany
01:52 AM IchGucksLive: problems: still online
01:52 AM gloops: it could be said hawking debunked einstein
01:52 AM gloops: at a stretch
01:52 AM IchGucksLive: gloops: he denight always
01:55 AM gloops: yes he would Ichs, i dont think he was in it to be the king
01:57 AM IchGucksLive: gloops: but its the outcome that counts
01:58 AM IchGucksLive: and at this time it is the best we got
01:58 AM IchGucksLive: sience first
01:58 AM IchGucksLive: im off
01:59 AM gloops: science will find another saint
02:22 AM Deejay: moin
02:33 AM pink_vampire: hi
02:33 AM pink_vampire: someone know about free nesting software?
02:48 AM miss0r: I hate working with odd angles :-/
02:48 AM miss0r: Hello pink_vampire
02:49 AM pink_vampire: the laser don't care
02:49 AM miss0r: not if its a 5-axis, no ;)
02:49 AM miss0r: Wanna see a picture of what I am working on ?
02:49 AM pink_vampire: yes
02:50 AM miss0r: https://imgur.com/a/tas9N
02:50 AM pink_vampire: H rails
02:51 AM miss0r: the sledge on the needs a open box of sorts to sit on there, to catch a cutoff when it drops. I am having issues figuering it out
02:52 AM miss0r: pink_vampire: This is what i've got so far: https://imgur.com/a/vyJyD
02:53 AM pink_vampire: it that for a saw?
02:53 AM miss0r: yeah
02:53 AM miss0r: an ID diamond saw
02:54 AM pink_vampire: ID??
02:54 AM miss0r: Innder diameter
02:54 AM pink_vampire: i know
02:54 AM pink_vampire: how ID?
02:54 AM miss0r: https://www.wotol.com/images/thumbs/800x800/1313059_c6e1c4c4d7ff0699fc1d551b532e49de.jpg
02:55 AM miss0r: That disk in there spins, and the workpiece is lifted into the cutting edge
02:55 AM pink_vampire: WOOOWW
02:55 AM pink_vampire: just insane!
02:55 AM miss0r: it makes realy acurate cuts, like mirror finish cuts
02:56 AM miss0r: And i've landed the nice little task of building a cutoff extractor
02:56 AM pink_vampire: ho you prevent them from getting dents?
02:57 AM miss0r: it even has a small printer on there, that every time you've completed a cut, it prints out measured deflection of the blade ect
02:57 AM miss0r: the blade ?
02:58 AM pink_vampire: the parts
02:58 AM miss0r: I'm installing padding in the box
02:58 AM miss0r: mostly to safe the box... The machine i'm building this for is only cutting silicium
02:59 AM miss0r: lol... silicon
02:59 AM miss0r: (tranlation)
02:59 AM pink_vampire: are you making wafers at home?
03:00 AM miss0r: lol no :] Its not my saw. I just landed an order for an extractor
03:02 AM miss0r: Haven't I mentioned; I became selfemployed by 1/3
03:02 AM miss0r: not "one third", but I started on my own the first of march
03:03 AM Wolf__: I was about to ask how does 1/3 self employment work lol
03:04 AM miss0r: Wolf__: Yeah, I thought that sounded funny
03:04 AM miss0r: bbiab
03:05 AM Wolf__: parts catcher, I would have just went with some plastic down spout and a acro bin =P
03:31 AM miss0r: Wolf__: yeah well, the client wanted something flashy :D
03:32 AM Wolf__: + IR switch, arduino and some blinking leds then
03:33 AM Wolf__: =D
03:33 AM pink_vampire: i need nesting...
03:33 AM pink_vampire: :((
03:33 AM pink_vampire: why it's soo complicated to find someting that will nest some part
03:34 AM Wolf__: what software
03:34 AM miss0r: I've always done that manually
03:35 AM pink_vampire: i need a software that will nest a file on a sheet material
03:35 AM Wolf__: ...
03:35 AM Wolf__: no kidding
03:35 AM Wolf__: what file type
03:36 AM pink_vampire: svg dxf what ever solidworks can save...
03:36 AM Wolf__: signets.com
03:36 AM Wolf__: err
03:36 AM Wolf__: http://svgnest.com
03:38 AM miss0r: bah. I think i'll need to go do this part in 2mm stainless steel sheet
03:38 AM pink_vampire: 304 is nice
03:39 AM miss0r: 316
03:39 AM miss0r: in this case
03:39 AM pink_vampire: i was joke
03:39 AM miss0r: (sarcasm translates horribly on IRC)
03:39 AM pink_vampire: i know..
03:55 AM * Loetmichel is just making enclosures on the mill again... i really like AlMg3... mills great. and doesent "smear" llike Al99 or similar. -> https://youtu.be/NJfZnqWUgfA
03:59 AM gloops: 123D cut, if you can get it
03:59 AM gloops: you want to cut a 3d model into 2d slices?
04:01 AM gloops: 123D make
04:01 AM gloops: not cut
04:06 AM gloops: for some reason i cant get this to install anymore on wine or windows 7
04:12 AM miss0r: Loetmichel: I see you like to live dangerously :)
04:18 AM fragalot: spotify broadcasting ads on their free version is one thing..I can live with that. but the least they could do is broadcast it in your language
04:20 AM miss0r: thats gonna be a solid no
04:24 AM miss0r: fragalot: This bucket for catching the parts are kicking my ass :]
04:24 AM fragalot: what's wrong?
04:24 AM miss0r: Either It will be hell to do in a 3-axis machine or it will look like shit
04:25 AM miss0r: I'm trying to break it down into manageable pieces now, but this one is a hard nut to crack
04:25 AM * fragalot is doing the same thing with STM32 timers at the moment
04:25 AM fragalot: all very simple, but the manual for timer5 alone is 93 pages
04:25 AM miss0r: by the way, did you want me to give you a quote on the tooling plate ?
04:25 AM miss0r: :D
04:26 AM fragalot: miss0r: sure, one machined & one raw stock if you don't mind? I'll get the other drawings done whenever I've got time as it's not urgent :)
04:27 AM miss0r: so: price of material & price of machining?
04:27 AM Loetmichel: miss0r: why?
04:27 AM fragalot: miss0r: That works - just want to know if it's worth me spending the time machining it, or if you can just do the lot & save me the "trouble" :)
04:28 AM miss0r: Loetmichel: that cutout in the video.. That core is bound to lock up at some point and mess up the endmill/surface finish
04:28 AM Loetmichel: it just flies out
04:28 AM miss0r: fragalot: sure, no problem. I'll need the link sent to me again, with the drawing :D
04:28 AM Loetmichel: somtimes it takes the mill bit with it, granted ;)
04:28 AM miss0r: Loetmichel: hehe
04:29 AM miss0r: Loetmichel: I do the same thing, but usualy I use a dap of superglue on a wasteboard, when doing stuff like that. Something I 'learned' the hard way :�
04:30 AM Loetmichel: i did
04:30 AM Loetmichel: but only three dabs for the whole part
04:30 AM miss0r: wasn't it yesterday?
04:30 AM fragalot: well that URL doesn't work here
04:30 AM Loetmichel: thats all what holds it to the vacuum table
04:30 AM Loetmichel: vacuum is off ;)
04:30 AM fragalot: yeah, if you remove the date from the URL you can read yesterday's
04:32 AM fragalot: miss0r: cutouts wrecking the part is something I learned the easy way
04:32 AM fragalot: all I had to do was push "star"
04:32 AM fragalot: t
04:32 AM miss0r: hehehe
04:32 AM miss0r: found it
04:52 AM XXCoder: :(
04:52 AM XXCoder: one of most brilliant minds died
04:52 AM miss0r: I was doing a contour at some point, and had too much unsupported material on the cutoff side. It cought the endmill and flung the workpiece in my general direction... Lesson learned: MOAR GLUE!
04:52 AM miss0r: yeah
04:52 AM XXCoder: same time he was defying his supposely lifetime by 3 to 5 times average
04:53 AM gloops: well he was 76 XXCoder, not really unexpected
04:53 AM XXCoder: most people with his condition dies at 30, gloops.
04:53 AM gloops: yes he was not expected to survive long enough to complete his phd
04:54 AM XXCoder: glad he did, and went very far.
04:57 AM gloops: yes not the typical theoretical physics career, he inspired a few generations to become interested in science maybe
04:57 AM gloops: i always like carl sagan
04:57 AM gloops: liked
04:58 AM gloops: sagan had some charisma, youve got to have a bit of rattle in that game
04:59 AM XXCoder: I didnt watch much of him
04:59 AM XXCoder: such shows was rarely captioned back then
04:59 AM gloops: he did speak english
05:00 AM XXCoder: and np captopns means he could speak any langiage and I would not understand him.
05:00 AM gloops: sagan presented cosmology in a way to inspire awe, how insignificant this little blue spot is etc, impressive to young minds
05:01 AM gloops: ahh you are deaf XXCoder?
05:01 AM XXCoder: nah im just ignoring you
05:01 AM XXCoder: ;) old joke
05:01 AM gloops: yes, sorry i didnt realise
05:02 AM XXCoder: no problem lol
05:03 AM gloops: well, theyve gone now, cant think of any current replacement
05:03 AM XXCoder: I do.
05:03 AM gloops: whos that?
05:03 AM XXCoder: Neil Tyson
05:03 AM XXCoder: hes awesome.
05:04 AM gloops: ill keep an eye out for him
05:05 AM XXCoder: oh I finally got the salt water lamp and usb charger. nice!
05:05 AM XXCoder: this time, tabs arent broken lol
05:05 AM gloops: what does it do?
05:05 AM XXCoder: tabs was made from wrong plastic so they all broke before they arrived. so they had to send everyone rewards again! ouch1
05:06 AM XXCoder: we all didnt have to send it back. so when I get Obsidian printer, I can just print new tabs lol
05:06 AM XXCoder: its zinc based led light for camping
05:06 AM XXCoder: can also charge usb stuff off it
05:06 AM fragalot: charge is a big word
05:07 AM fragalot: is it one of those things that you "just add salt water" to power?
05:07 AM XXCoder: not even that, for first 3 dips, just need water
05:07 AM XXCoder: I guess salt runs out after that so need salt afterwards.
05:07 AM gloops: is this from a preppers site?
05:07 AM XXCoder: https://www.kickstarter.com/projects/1993414184/the-hydra-light-pl-500-salt-water-energycell-lante
05:07 AM XXCoder: picture is of old model
05:07 AM fragalot: I can't imagine getting the 1W required to start charging a phone
05:09 AM gloops: well, back to my little pit, pc booted up after getting dripped on for 2 days lol, i can now see the hal config and connect the pins up
05:09 AM XXCoder: dripped on?
05:10 AM gloops: yeah snow must have damaged garage roof, ill have a look at it later
05:10 AM XXCoder: ahh was thinking maybe under machine, oil dripping on it
05:11 AM gloops: the leak was of course straight over the PC and keyboard
05:11 AM XXCoder: fragalot: one of things I liked about it is essentally infinite shelf life
05:14 AM XXCoder: keyboard isnt bad as long as liquid isnt acidic
05:14 AM XXCoder: pc well it depends lol
05:18 AM fragalot: XXCoder: have you tried to check how long it actually takes to charge a modern cellphone on it?
05:18 AM jthornton: morning
05:18 AM XXCoder: probably a while but same time zinc contains pretty lot of power
05:19 AM XXCoder: you could also make aluminium batteries, it makes much more power but harder to activate (cant just use salt water) and alum requires lot more power to remake than zinc
05:26 AM XXCoder: HMMMM new one https://www.chemistryworld.com/news/super-fast-charging-aluminium-batteries-ready-to-take-on-lithium/8427.article
05:26 AM XXCoder: 2015 to now, I dont think it will take off however
05:30 AM XXCoder: too bad. alum is much much more common than lathinium.
05:44 AM Tom_L: morning
05:44 AM jthornton: morning
05:45 AM Tom_L: 30�F
05:46 AM Tom_L: we're flooded with NCAA today
05:46 AM XXCoder: NCAA?
05:46 AM Tom_L: google knows
05:46 AM XXCoder: sometimes. but ok lol
05:47 AM Tom_L: basketball
05:47 AM XXCoder: yeah
05:52 AM miss0r: fragalot: i've come up with a solution to the bucket here :) I'll make a skeletal structure, and have "flat robe' mesh between them
05:52 AM miss0r: like the stuff you see in every fight scene on a cargo plane ;)
05:53 AM fragalot: interesting
05:53 AM miss0r: i'm leaning more towards 'functional'
05:54 AM miss0r: well, going to go cut the first now.
05:54 AM fragalot: :-)
05:55 AM nallar is now known as Ross
05:59 AM Loetmichel: *meh*. just tried to start my (parked for the winter) BMW convertible... *KLACK* *dash lights go off*... i should have learned by now that a month without engine running is to long for that battery. *unpacks the jumper cables again*... thats NOT good for the battery :-(
06:00 AM XXCoder: you should get die hard battery maintancer
06:00 AM XXCoder: its around 35 bucks? cheaper than new battery
06:04 AM miss0r: fragalot: What type of aluminium were you thinking? some T6 ?
06:07 AM fragalot: miss0r: my requirements are: _FLAT_, _STABLE_, easy to machine.
06:08 AM miss0r: choose two
06:08 AM miss0r: :]
06:09 AM XXCoder: happy pi day
06:11 AM miss0r: fragalot: is 20mm critical? (i.e. can I order 20mm stock and square it off/ordering 25mm stock)
06:32 AM Loetmichel: XXCoder: th car is parked at the company. outside on the parking lot
06:32 AM Loetmichel: cant put a permanent extension cord there
06:32 AM XXCoder: oh if its to be stored long term just remove battery leave it plugged in somewhere
06:33 AM miss0r: lunch
06:34 AM Loetmichel: i prefer to start it every two weeks and run it for an hour++
06:34 AM Loetmichel: that way it also dries a bit
06:34 AM Loetmichel: ( canopy is a bit leaking)
06:34 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=16953&g2_imageViewsIndex=1
06:35 AM XXCoder: high end top
06:35 AM Loetmichel: temporay pallet wrapping foil to prevent the 5cm water in the foot well i had last month
06:36 AM XXCoder: drill holes ;)
06:36 AM XXCoder: drill hole, use rust eating paint on hole lol
06:37 AM gloops: motor power back on all axis, another tick
06:42 AM fragalot: miss0r: 20mm is not critical depending on the part,.. if I know the final dimensions I can adjust the hole spacing on some parts to match, and others I prefer to drill "in situ" anyway
06:47 AM gregcnc_: Is that autobahn approved?
06:48 AM gloops: thats a bin liner and some scotch tape?
07:29 AM miss0r: fragalot: i've just requested a quote on the material. Have you considered using cast iron?
07:30 AM fragalot: miss0r: considered; yes, but I wasn't sure if the rather large increase in cost was worth it?
07:30 AM miss0r: hmm. If your rails can handle it, I would say so
07:31 AM fragalot: the rails & motor should be fine with cast iron
07:31 AM miss0r: now that you have gone through(or soon will) all the trouble of casting EG.
07:31 AM fragalot: just couldn't find any sources for that stuff
07:31 AM miss0r: I can get a quote on that as well
07:31 AM fragalot: sure
07:33 AM miss0r: alu is much more likely to bend a bit and also to vibrate
08:07 AM Loetmichel: gloops: no bin liner, shrink wrapper for euro pallets. and no, gregcnc_, it is not. its just to prevent "filling up" the foot wells with rain beause of the missing waterproofing in the canvas.
08:07 AM Loetmichel: while it sat there for a few (winter) months
08:14 AM miss0r: fragalot: they are taking their sweet time sending me the quote. I can tell you this much: 6m 310x20 T6 aluminum costs aprox 550EUR (excluding tax, which is 25% here). They are not looking at what it would cost to get a 450mm long peice. :)
08:14 AM miss0r: not=now
08:17 AM fragalot: That's fine.
08:17 AM fragalot: curious how much the cast iron would be
08:17 AM fragalot: also, I should know better than to ask a danish person for things - your tax rates are insane, even by belgian standards
08:17 AM fragalot: :D
08:18 AM miss0r: yeah :]
08:19 AM gregcnc_: does the customer also pay tax on the parts you make for them?
08:19 AM miss0r: fragalot: my usual supplier of cast iron does not stock the size I want. And I'm not feeling like getting 2 tons :) Also, when it comes to shipping I think alu is funnier.... I do have a few slabs of steel that are 30mm thick laying around, if that could intrest you
08:19 AM miss0r: gregcnc_: yeah
08:20 AM fragalot: gregcnc_: in belgium, the customer pays the tax, the company making the item has to pay it first, but gets it back via their tax returns;
08:20 AM gregcnc_: so the material in the product isn't actually taxed
08:20 AM miss0r: I pay tax 2 times a year. The amount I pay is tax for outcomming - tax for outgoing
08:21 AM fragalot: miss0r: let's just stick with alu for now then.. how stable is T6?
08:21 AM fragalot: eg. will it warp over time?
08:21 AM miss0r: hehe. everything warps over time. But not thise size under its own weight
08:22 AM miss0r: T6 is pretty hard
08:23 AM fragalot: miss0r: k :) -- it's just certain materials have more of a tendency to warp than others due to internal stresses
08:23 AM fragalot: cast iron is a great example if it's not aged properly
08:25 AM miss0r: fragalot: http://www.aluminco.com/media/155961/ALUMINIUM-ALLOY-EN-AW-6060_MATERIAL-DATA-SHEET_ALUMINCO.pdf
08:25 AM miss0r: What I asked for a price on: AW6060/6063 T6 AlMgSi0,5
08:26 AM fragalot: k
08:26 AM miss0r: its commonly referred to as tool aluminium
08:27 AM miss0r: If you pay for it, I wouldn't mind having the rest of the 6m length laying around :P
08:27 AM miss0r: So, not interrested in my mystery metal sheet?
08:27 AM miss0r: :]
08:30 AM fragalot: miss0r: not...really? :D
08:30 AM fragalot: 2 main reasons
08:30 AM miss0r: :D
08:30 AM fragalot: a) it's mystery steel of mystery proportions
08:30 AM fragalot: b) .dk taxes are hell. :P
08:31 AM miss0r: ahh :) but this I have in stock, so we need not worry about taxes on that ;)
08:31 AM miss0r: Only the shipping that will be nuts :D
08:31 AM fragalot: meh - I hve that issue regardless where I get it :P
08:32 AM gregcnc_: are you that far from a metal supplier?
08:32 AM miss0r: Well, it will weigh in at around 19kg (if it is mystery metal)
08:33 AM miss0r: and only 6kg if 6063 :o
08:33 AM miss0r: that doesn't sound like alot
08:33 AM fragalot: gregcnc_: I am that far from metal suppliers that want to sell to private customers
08:34 AM miss0r: fragalot: The mystery metal will cost ~100eur to ship and the aluminium one will cost 75eur ish
08:35 AM fragalot: miss0r: but do you have enough to do everything in that mystery metal
08:35 AM miss0r: so far i've only seen one drawing :]
08:35 AM fragalot: miss0r: and how much will the difference be for everything? :P
08:35 AM fragalot: hehe
08:36 AM miss0r: BUT... the metal I have here is ~33mm thick so.. yeah. either I need to shave it down like a mad man or the package will be heavy :D
08:37 AM fragalot: what would the finished thickness of the alu be after you've flattened it?
08:38 AM miss0r: If the material I get is pretty flat, then 19 perhaps
08:38 AM miss0r: 19.5? depends on the material
08:39 AM fragalot: I'll need to know ot adjust the holes so everything still fits
08:40 AM miss0r: Indeed. 19 I can be sure to hit
08:41 AM miss0r: lets focus on the aluminium. the drawing you sent me, is that the biggest part?
08:43 AM fragalot: I'd need to check
08:43 AM fragalot: I remember increasing the size of the Z and Y plates, don't have the latest drawing with me
08:44 AM miss0r: No worries. We are both working at the moment ;)
08:59 AM Loetmichel: *WHAT* a ratsnest... there were times when i did better... aw, who cares if it works. It probably a one-off again. no need to make it pretty. just fast. http://www.cyrom.org/palbum/main.php?g2_itemId=17025&g2_imageViewsIndex=1
09:07 AM enleth: Loetmichel: seen worse
11:41 AM rwlloyd: Afternoon all.
11:43 AM rwlloyd: Does anybody have any good resources that may help me get an external E-Stop button working with LCNC? I've been scratching my head for a day or so and not really understanding the docs.
11:44 AM gloops: stop button, using a breakout board and parport?
11:50 AM Loetmichel: *haach* niiiice... i just drove my BMW 318i convertible home after 5 months of parking it at the company... *bad hair now* feels great to drive open... but i have to adjust to sitting nearly directly on the tarmac instead of 30cm higher as in my winter car. ;)
11:55 AM gloops: rwlloyd ive not done one, but basically wire the switch to an input pin and ground it on the inputs ground, allocate the pin in stepconfig? or hal
11:56 AM gloops: should get some weather for it soon enough Loetmichel
11:56 AM Loetmichel: here it is already good enough
11:57 AM Loetmichel: 11°C, sunny, not tooo windy, not that many clouds. perfect for an open ride ;)
11:57 AM gloops: its not been bad today here but forecast some cold weather returning, another month we should be in the clear
11:57 AM gloops: ive been in a t-shirt today
11:57 AM Loetmichel: i am ALWAYS in a tshirt
11:57 AM gloops: lol, tbh i have been mainly indoor or the garage or car
11:59 AM Loetmichel: <- has been caught shoveling snow in tshirt an jeans a few years back
11:59 AM Loetmichel: <- not that easily feeling cold
11:59 AM gloops: yes im getting soft in my old age
12:02 PM phipli: annnnd rest
12:02 PM * phipli slumps in the corner
12:08 PM rwlloyd: Hi, Sorry, got dragged away for a while. Yes, it's using a parallel bob, one of those chinese 5 axis ones with a relay built in.
12:10 PM gloops: rwlloyd as above, select an input pin 10-14 i think it will be, wire one wire to that, through the switch back to ground
12:10 PM gloops: http://www.gbeshop.com/InfoBase/SAVEBASE/PKG/004393/Image/New_5axis_breakout_board_interfaces_fw_r2_c1.jpg
12:10 PM rwlloyd: I have a NC switch. Connecting it between pin 15 and GND does nothing,
12:10 PM gloops: left hand side there
12:11 PM rwlloyd: yep, thats the one, I have it between p15 and GND
12:11 PM gloops: a 2 pin switch?
12:12 PM rwlloyd: yes
12:12 PM gloops: and you set emergency stop to pin 15 in stepconfig?
12:13 PM rwlloyd: yep, pin15, ESTOP-in
12:13 PM gloops: ok, have got any other switches wired up?
12:13 PM gloops: home switch, limits etc
12:14 PM rwlloyd: no, nothing. The machine doesnt need them
12:14 PM gloops: right
12:14 PM gloops: you have got a 12v supply to the bob?
12:16 PM rwlloyd: no..... i thought that was just for the spindle power supply. I thought the power for the inputs came from the USB from the PC?
12:17 PM gloops: nope, no 12v, no input pins
12:18 PM gloops: if it is the same bob as you one above an led will light beside the input pins to show they are active - once you supply 12v
12:18 PM rwlloyd: well, don't I feel the fool. Thanks.
12:19 PM rwlloyd: ahhh, it's going to be 24V but that shoudl be fine it says.
12:19 PM gloops: yes i spent a couple of days kicking stuff around in the garage until i realised that one lol
12:21 PM rwlloyd: ooh look, a new light
12:22 PM gloops: well i gotta feed the chckens and pick the mrs up bbl
12:22 PM rwlloyd: and it works!
12:22 PM gloops: nice one
12:22 PM rwlloyd: home time for me too, I'll p;lug it into the laser tomorrow!
12:23 PM rwlloyd: cheers man, you've saved me a lot of head scratching
12:23 PM Tom_L: gloops did his deed for the day!
12:24 PM rwlloyd: should I feel violated in any way?
12:59 PM IchGucksLive: hi all from a colder germany
12:59 PM IchGucksLive: snow in forcast for this weekend
01:00 PM Loetmichel: IchGucksLive: CLOD?
01:00 PM Loetmichel: COLD?
01:00 PM Loetmichel: i just drove home from work with my BMW with open roof
01:00 PM IchGucksLive: -4 in forcast for saturday
01:00 PM Loetmichel: nice and cozy 11°C here
01:00 PM Loetmichel: atm
01:01 PM IchGucksLive: gloops ?
01:01 PM IchGucksLive: rwlloyd: you did got trapped in the china cache
01:01 PM IchGucksLive: 12V not pluged in
01:02 PM roycroft: hopefully we're done with freezing temperatures for the year
01:02 PM roycroft: for the season, rather
01:02 PM roycroft: that said, temperatures are below average here
01:03 PM roycroft: 11 today will be the high, and a low of 2
01:03 PM roycroft: average high this time of year is 13
02:08 PM gloops: all quiet on the Western front
02:08 PM fragalot: fighting fusion360 here
02:08 PM gregcnc_: dishwasher broke here replaced this morning
02:09 PM gloops: pump gregcnc?
02:10 PM gregcnc_: shaft seal
02:10 PM gregcnc_: again
02:12 PM gloops: i seem to think ill be doing the fusion 360 thing someday, not much of what i hear is very encouraging though
02:13 PM gregcnc_: a lot of people are using it
02:15 PM gloops: yeah loads on facebook, its the standard free app
02:16 PM gregcnc_: what have you heard?
02:16 PM gloops: i see a lot of people struggling with it
02:17 PM gregcnc_: struggling because they are CAD newbs or?
02:17 PM fragalot: i'm far from a CAD newb, but i'm just spoiled
02:18 PM gregcnc_: well i struggled with it too when i tried. been driving SW for 20 years, but I didn't see anyhting i couldn't overcome
02:18 PM gloops: it may be they are cad newbs yes, i had a quick look once and i didnt like the look of it
02:19 PM gloops: a lot dont realise you have to put some hours in with these apps
02:19 PM fragalot: gregcnc_: it's certainly not something that can't be overcome, but everything just takes soo much longer to do in f360 compared to inventor 2017
02:19 PM gregcnc_: Sure but seat cost?
02:20 PM fragalot: no competition there
02:20 PM gloops: i need a decent windows machine anyway, only got old laptops with windows on
02:21 PM fragalot: especially for hobby use, the hour I spend on changing the plate thickness (and of course all of the joints that implode as a result), is not worth the 45k a year that Inventor costs
02:22 PM gregcnc_: like anything, compromise
02:23 PM fragalot: doesn't mean I don't get to bitch about it :P
02:24 PM gloops: my stuff will be more art than part, so i can get away with whatever looks right heh
02:24 PM gloops: with some basic dimensions and fixed points
02:25 PM CaptHindsight: Trump CAD, no compromises!
02:25 PM gloops: TrumputinCAD
02:25 PM XXCoder: 2+2=3
02:26 PM CaptHindsight: all the models come out distorted
02:26 PM gregcnc_: like gluegun printers?
02:26 PM XXCoder: and possibly not ecludian
02:26 PM CaptHindsight: or Escher
02:27 PM gloops: and might not behave as normal objects in gravity
02:27 PM XXCoder: I always mispell that word.
02:27 PM CaptHindsight: Euclid?
02:28 PM XXCoder: yep lol
02:28 PM CaptHindsight: anyone have a source for 4ft (1.3m) dia acrylic tube or sections?
02:28 PM gregcnc_: shite
02:29 PM * fragalot has just spent the last half an hour trying to hunt down that one (combination?) of joints that screw everything up
02:29 PM CaptHindsight: shower stall are closer to 33" (.8m)
02:29 PM gloops: in freecad you just grab the sketch and shake it to see what freedom remains
02:30 PM gregcnc_: I wonder if they care if you are nowhere near in the market for their machines https://us.dmgmori.com/news-and-media/events/innovation-days-chicago
02:30 PM gloops: 1.3m acrylic? nah, you might get a plastic drain pipe that size
02:30 PM gloops: probably a bendy one
02:31 PM CaptHindsight: needs to be clear
02:31 PM XXCoder: work someone had to order few tubes of similiar length and diameter. not sure if arcylic
02:31 PM gregcnc_: those Tanked guys make all sort of shapes and thick like 50mm
02:31 PM CaptHindsight: or I'll just use stainless
02:31 PM XXCoder: but yeah clear. lighting solutions?
02:31 PM CaptHindsight: https://plastic-domes-spheres.com/shop/36-outer-diameter-x-46-long-rolled-cylinder
02:32 PM CaptHindsight: close but they can make them any size
02:32 PM CaptHindsight: just need a big oven and a form https://www.youtube.com/watch?v=45ivldW3eIQ
02:33 PM XXCoder: nice
02:33 PM XXCoder: I saw video where guys made half sphere
02:33 PM XXCoder: pretty amazin
02:34 PM XXCoder: https://www.youtube.com/watch?v=ZlBQME0aB2s
02:34 PM CaptHindsight: need to borrow a pizza shop
02:34 PM fragalot: gloops: that works fine, up until the point where you have an assembly with over 50 parts, and each of the parts have mating features with joints on them that depend on each-other to be identical
02:35 PM fragalot: so you need to find the part that is causing the misalignment, find what dimension it is that needs changing, change it, update the assembly, wait for it to process everything,.. find out that wasn't it, or there is still something else.
02:37 PM gloops: lol, see and people call freecad hard work
02:38 PM fragalot: this is the same in any CAD package
02:38 PM fragalot: the only difference is how clear it marks the culprit
02:38 PM fragalot: or how easy it is to isolate the offending parts
02:38 PM gloops: yeah you wouldnt be going to 50 parts in FC
02:38 PM fragalot: or how well it inter-links the features
02:39 PM fragalot: gloops: at work I used to make assemblies with thousands of parts in Inventor
02:39 PM XXCoder: fc dont have working assembly yet
02:39 PM fragalot: worked fine.. most of the time. sometimes it literally exploded & it was easier to start over.
02:41 PM fragalot: I guess the thing I miss most in fusion360 are simple constraints
02:43 PM CaptHindsight: never tried 360, NX, Catia, SW etc pretty much work the same on the surface, Freecad not so much
02:43 PM XXCoder: theres 3 versions of assembly for freecad. last version assembly3 is still being worked on. other 2 developer left
02:44 PM gregcnc_: lol boating in winter https://youtu.be/nQiluaApU-A?t=3m23s
02:44 PM gloops: apparently assembly is working in the next stable release
02:45 PM XXCoder: gregcnc_: lol perment wake
02:47 PM XXCoder: gregcnc_: if we had snows more often it'd be great for kickstarter - snow boats lol
02:48 PM gregcnc_: have to catch Zeeshan next time he's here
02:50 PM Tom_L: should be easy... doesn't appear to be a fast runner
02:52 PM CaptHindsight: Snowboat - the musical
02:52 PM Tom_L: fragalot, f360 wasn't meant to do assemblies well ehh?
02:52 PM Tom_L: haven't tried that yet
02:56 PM CaptHindsight: hawking passed away on pi day
02:56 PM CaptHindsight: coincidence
02:56 PM gloops: it is a strange day
02:56 PM XXCoder: usually I eat a pie but not this year
02:56 PM gloops: hawkings died, and also, im now sat here 45 minutes away from being vaporised
02:57 PM gloops: at any moment
02:57 PM gregcnc_: gee which propoganda site do you read?
02:57 PM CaptHindsight: Vicks + humidifier?
02:57 PM XXCoder: you standing now eh?
02:57 PM gloops: UK has expelled all russian diplomats and called a UN meeting
02:57 PM gregcnc_: well it over now
02:58 PM Tom_L: are they stirring up trouble over there?
02:58 PM gloops: i dount it, this stuff is going to real, i can feel it in my bones
02:58 PM gloops: going to get real
02:58 PM fragalot: Tom_L: I think they tried to simplify it but went too far.
02:58 PM gregcnc_: wife had pie at work today
02:59 PM gloops: Tom_L nothing really alarming yet, but you know how these things can escalate
02:59 PM gregcnc_: to nuclear war?
02:59 PM gloops: easily
02:59 PM gregcnc_: hah
02:59 PM Tom_L: we sneak up in the middle of the night...
02:59 PM gloops: the russian economy is collapsing, putin really needs a war
03:00 PM gloops: hes got a brewing revolution on his hands
03:01 PM fragalot: finally! found it.
03:01 PM fragalot: if you do a "copy & replace", it only does it on that one part, not on all entities of that part.
03:02 PM gloops: just as i thought fragalot - user error
03:02 PM fragalot: now how do I replace the other parts...
03:02 PM fragalot: gloops: I don't think that was ever up for debate? :)
03:03 PM fragalot: like I said, regardless of the CAD package, the only difference in joint errors like this, is how easy it is to find it
03:04 PM gregcnc_: there are guys running DMG DMU60 Evo and such from F360. That blows me away, but I don't think they design anything in F360
03:04 PM fragalot: the CAM part is quite powerful
03:04 PM Tom_L: yeah that part looks nice
03:04 PM Tom_L: have you watched their videos?
03:05 PM fragalot: does anyone know how to replace a part without using "save as & replace" ?
03:05 PM gregcnc_: I found a post that I think will work for lathe 3D C axis stuff.
03:05 PM Tom_L: i think you can edit them too if you know how
03:06 PM Tom_L: that's on my list of things to look at in it
03:08 PM gregcnc_: yes, editing is no trouble if you know how. i only know enough to be dangerous. I modified a post from milling to give me code for G12.1 milling in lathe.
03:09 PM Tom_L: did you find any instructions or help on that part of it?
03:09 PM Tom_L: as far as sections and format
03:09 PM gregcnc_: tons of stuff in the autodesk forums, there is a basic manual at the top of the post processors forum
03:09 PM Tom_L: most new post of any kind are alot different than my old ones
03:10 PM CaptHindsight: whats the name of those sanitary food grade pipe fittings
03:10 PM CaptHindsight: they use them for brewing as well, all in SS
03:10 PM Tom_L: ss or plastic?
03:11 PM CaptHindsight: SS
03:11 PM CaptHindsight: http://acesanitary.com/products/sanitary-fittings
03:11 PM fragalot: well. this is mildly annoying.
03:11 PM CaptHindsight: https://www.dixonvalve.com/markets/food-beverage-processing
03:12 PM Tom_L: i don't think assembly constraints are foolproof in any cad package
03:14 PM fragalot: seems the "replace parts" has been a feature request since 20015.
03:14 PM fragalot: 20015*
03:14 PM fragalot: 2015*
03:14 PM Tom_L: ok, i'm off again..
03:15 PM fragalot: so the only solution is to remove all joints & dependent joints, delete the part, put in the new part, add all the joints again
03:15 PM fragalot: might as well start over
03:16 PM gregcnc_: if it's that bad, I doubt any other software would help much
03:16 PM gregcnc_: if the id'd of the joints don't match it would fail anyway
03:16 PM fragalot: inventor can do it easily, i'm sure SW can do it too
03:16 PM fragalot: the frustrating part is that they have a "save as and replace"
03:16 PM fragalot: but it only works on that one component
03:17 PM fragalot: so you can't replace the 40 other instances
03:18 PM gloops: ive just bought a remote control bought lol, for absolutely no good reason
03:18 PM gloops: bought - boat
03:18 PM gregcnc_: well it doesn't snow there often so what will you do with it?
03:20 PM gloops: i dunno, i saw my mate with one on a local duck pond, hes got this boat that was hand made like a perfect replica of a lifeboat, i just saw this similar one going really cheap round the corner so i got it
03:20 PM gregcnc_: I want to build one here soon.
03:20 PM gloops: ill be able to chase the ducks as well now
03:21 PM gloops: this is only a small one gregcnc like 18 inch long - not a real boat
03:21 PM gregcnc_: well this one will be 26"
03:24 PM gloops: the one my mate has is really nice, little lights in the cabin and on the mast, lots of detail, id love to make one but no time
03:47 PM adamj12b: Tom_L: Hey Tom, My search for variables continues. I found a chunk of information in the manual.
03:48 PM adamj12b: http://linuxcnc.org/docs/2.7/pdf/LinuxCNC_Documentation.pdf page 202 is the start
03:50 PM adamj12b: I also have found a variable of what coordinate system is active, in that same section
04:11 PM gloops: ‘Gunman’ on loose at Northwestern University in the US
04:13 PM gregcnc_: http://www.chicagotribune.com/news/local/breaking/ct-met-northwestern-university-shots-fired-evanston-20180314-story.html
04:15 PM fragalot: so.. false alarm?
04:17 PM Deejay: gn8
04:19 PM gloops: hopefully yeah
04:26 PM phipli: Tom_L, http://elephantandchicken.co.uk/PCBs/threecats.mp4
04:28 PM JT-Shop: hey phil
04:28 PM phipli: evening JT
04:28 PM phipli: how goes?
04:28 PM JT-Shop: not bad
04:28 PM JT-Shop: how about you?
04:28 PM phipli: :)
04:28 PM phipli: tired
04:28 PM phipli: been very busy at work
04:29 PM phipli: not done anything much other than work, sleep and eat in the last couple of weeks
04:29 PM JT-Shop: yuck, that project I'm working on is being a pia lol
04:30 PM fragalot: JT-Shop: what's it (not) done this time?
04:30 PM phipli: I finished my part of the project today
04:30 PM phipli: so from tomorrow, after we deliver it, I'm free
04:30 PM phipli: planning to take Friday off because I worked the last two weekends
04:30 PM phipli: not still the rock polisher is it?
04:33 PM gloops: 2 weekends on the trot...
04:33 PM * gloops shudders
04:34 PM phipli: two 60 hour weeks
04:34 PM phipli: three nights past 11:30 in a row...
04:34 PM phipli: and two of them were the weekend
04:34 PM JT-Shop: yea the polisher, blew two control transformers because the plant has 500v
04:34 PM gloops: well, gonna be a fat pay packet though phipli
04:34 PM phipli: gloops, don't get overtime
04:34 PM JT-Shop: it's just a pia to get the parts to flow and they changed a bit how it goes inline
04:35 PM gloops: no overtime?
04:35 PM phipli: nope
04:35 PM phipli: they believe it would encourage people to drag work out
04:35 PM * fragalot doesn't get overtime either
04:35 PM JT-Shop: found out 480v control transformers blow up at 500v so I have to get a multi tap transformer
04:35 PM phipli: because, you know, it isn't like we like going home or anything
04:35 PM fragalot: not anymore anyway
04:35 PM * JT-Shop neither
04:36 PM phipli: JT-Shop, what voltage were you expecting?
04:36 PM phipli: ah right, 480
04:36 PM * JT-Shop works everyday unless the wife tells me not to
04:36 PM JT-Shop: yea usually it's 480v here
04:36 PM gloops: i cant work more than 3-4 days now, im too old
04:36 PM fragalot: JT-Shop: still weird though that the transformers just.. blew up with such a small difference
04:37 PM gloops: the mrs still does 60-80 hour weeks though lol
04:37 PM fragalot: you'd think they would be able to take it, but just give a too high output
04:37 PM phipli: yeah... the insulation should be good for quite a lot over...
04:37 PM phipli: usually current that kills transformers
04:37 PM phipli: current = heat
04:38 PM phipli: they didn't give it twice as much work as it should have had did they?
04:38 PM phipli: like put a /really big/ chicken in it?
04:38 PM fragalot: phipli: apparently they blew up, open load
04:38 PM phipli: blimey
04:39 PM JT-Shop: nothing hooked to the output
04:39 PM gregcnc_: 4% over shouldn't kill it
04:39 PM phipli: I wonder if they have a dodgy supply?
04:39 PM gregcnc_: step down? connected to the output?
04:40 PM phipli: is it "nominally" 500v
04:40 PM phipli: which on trains would mean, "anything between 100v and 1000v"
04:40 PM JT-Shop: the plant used to have 40+ plastic injection presses so the guy that used to work there thinks they bumped it up because of the load
04:40 PM gregcnc_: my house was reading up to 263V last winter
04:40 PM phipli: gregcnc_, what country?
04:41 PM phipli: UK?
04:41 PM gregcnc_: usa
04:41 PM phipli: that's... more than double?
04:41 PM phipli: you could have used our tools
04:42 PM phipli: (we're spec'd at 240 -10% +15% if I remember...
04:42 PM phipli: but I might be wrong
04:43 PM gregcnc_: where is that?
04:43 PM phipli: the tolerance is intentionally large so we can pretend we have the same voltage as the continent
04:43 PM phipli: we're in the UK
04:43 PM phipli: UK is a mix of 240 and 250 (mostly 240)
04:43 PM phipli: europe is 220 (perhaps some 230?)
04:44 PM fragalot: anywhere between 220 and 240
04:44 PM SpeedEvil: It's recently been announced post-brexit, we're moving to 100V.
04:44 PM fragalot: depending on what they feel like in that particular region
04:44 PM SpeedEvil: (not really)
04:44 PM phipli: fragalot, I believe some places (not many) still have 250
04:44 PM gregcnc_: this is both hot legs so 240, our normal outlets are only leg and neutral so half that
04:45 PM * fragalot only has 3x240V "hot", no neutral in sight
04:45 PM phipli: SpeedEvil, the speed at which everything with a motor would operate would probably reflect the general mood :)
04:45 PM gregcnc_: i looked at the tolerance, but it was over for sure
04:45 PM gregcnc_: no problems this year
04:46 PM dioz: is welding aluminium easy?
04:46 PM fragalot: dioz: it's.. weird
04:46 PM phipli: reading the internet and it seems they claim "230 +10, -6%" these days
04:46 PM fragalot: best way I can describe it is that it's like spreading very lightly molten chocolate
04:46 PM dioz: cool
04:47 PM phipli: if you measure the outlet it hasn't change, regardless of all the changes they claim
04:47 PM phipli: tis all lies, damn lies and statistics
04:47 PM fragalot: dioz: it also needs a lot more power than steel, depending on the thickness you may also need to pre-heat the work
04:47 PM andypugh: Is this guy a troll or am I missing something? https://youtu.be/N1XwgdnA93I (The video is mine, I am referring specifically to the most recent comments)
04:48 PM phipli: aren't all youtube commenters 12 and trolls?
04:48 PM gregcnc_: you're worried about YT comments?
04:49 PM andypugh: Not worried, I am just wondering if I am missing something. Also not sure what I have done to wind him up.
04:50 PM phipli: his profile page is quite sparse
04:50 PM phipli: google search says he likes commenting on machining videos
04:50 PM andypugh: Do any comments make more sense?
04:52 PM gloops: name looks russian
04:52 PM phipli: nah
04:52 PM phipli: scandaweegen
04:52 PM gloops: nah, scando
04:52 PM fragalot: that is most certainly not russian
04:52 PM gloops: yeah
04:53 PM gloops: probably cabin fever, been a long winter
04:53 PM JT-Shop: what a turd head comment
04:53 PM BeachBumPete: hehehe what a jackhole
04:55 PM phipli: Youtube is a special place
04:55 PM phipli: He is Danish
04:56 PM BeachBumPete: special is a good word for it ;)
04:56 PM dioz: spechul
04:56 PM dioz: can't get over how much i love posting shit on peoples youtube videos
04:57 PM dioz: ;]
04:57 PM phipli: ah right, it was dioz
04:57 PM phipli: mystery solved :p
04:57 PM fragalot: can't trust those danes
04:58 PM gregcnc_: the first reply is to ask him what he would have done different. either he'll give a proper answer or keep up with the bs, then you know
04:58 PM gregcnc_: he seems to know something
04:59 PM phipli: some lathes were built with an ark in them that levelled when you put it all together weren't they?
04:59 PM BeachBumPete: Yeah he knows how to be an azz
04:59 PM phipli: is he thinking of that?
04:59 PM gloops: hes probably got a massive pile of fishing nets to untangle
04:59 PM phipli: and rotten fish for dinner? or is that the wrong country
04:59 PM gregcnc_: I read a lot of his other comments, yeah he's brash, but some were on point
05:00 PM gloops: phipli there are some that are designed not to be levelled, or dont require any levelling
05:00 PM phipli: *arc
05:00 PM andypugh: So, does anyone else think that I am making a curve?
05:01 PM * phipli is unqualified to answer
05:01 PM andypugh: (That lathe sits on a 3-point suspension, and is basically a solid bar of iron anyway)
05:01 PM * phipli recommends you stick to asking him questions about trains
05:01 PM dioz: idk andy but...you gonna take him up on the scrap?
05:01 PM dioz: fighting is fun IMO
05:02 PM fragalot: andypugh: easy. put the DTI back on & check.
05:02 PM andypugh: I will just wait a week and delete his comment.
05:02 PM andypugh: The lathe slides from end to end now, to that’s job done as far as I am concerned.
05:02 PM phipli: ask him how he proposes to plane it with a hammer
05:03 PM andypugh: Nah, I am just going to ignore him.
05:03 PM phipli: :)
05:03 PM dioz: aaw =/
05:03 PM dioz: you should youtube the fight vid
05:03 PM SpeedEvil: But someone is wrong on the internet!
05:03 PM andypugh: www.xkcd.com/386
05:04 PM dioz: worldstar!!!
05:04 PM gloops: i dunno, sometimes it takes an offish comment to start a debate - where things can be learned, he ought to elaborate and explain his point
05:04 PM dioz: tomorrow i have to draft an oblique cone and a right cone
05:04 PM andypugh: (Yes, I do know that URL without having to check it)
05:05 PM dioz: 11/12 spacing
05:05 PM SpeedEvil: That one and 123 are the ones I remember
05:05 PM andypugh: Yes, 123 is centrifuge
05:06 PM andypugh: I quoted 927 to Gina from Octoprint yesterday and she knew what I meant without looking.
05:07 PM andypugh: But I had to look up 356 just now because I had forgotten it.
05:07 PM phipli: he might work for a farm equipment dealership or manufacturer...
05:07 PM phipli: Skiold...
05:11 PM gloops: a bowed bed would be manifest in the cut - along the length, variation in diameter
05:15 PM gregcnc_: in the end, regardless of what defects the machine has, if parts are acceptable that all that matters
05:16 PM gloops: ive got a crack in the top slide, still works ok for me
05:16 PM gloops: i darent try welding it it will probably crack all way through
05:18 PM dioz: gloops: is your room clean?
05:20 PM gloops: hmmm..no not really
05:21 PM gloops: i had 30 minutes with the dustpan and brush this morning though
05:21 PM dioz: well that's good
05:22 PM dioz: are you the kind of guy to go out and picket the system?
05:22 PM Tom_L: phipli, cute
05:23 PM gloops: not really dioz
05:23 PM gloops: not that i dont care, i just know it wouldnt make the slightest bit of difference
05:24 PM dioz: what if i was to say... if you aren't able to keep your room clean... what makes you think you'd make a reasonabledifference being responsible for something else?
05:25 PM phipli: Tom_L, practice for electronic christmas cards this year
05:25 PM gloops: i tend to avoid being responsible for anything else
05:25 PM gregcnc_: If i wanted to hear from my mom I'd call her
05:25 PM phipli: total cost (excluding battery) is about 50p, including the board
05:35 PM Tom_L: andypugh have you seen anything that guy has done?
05:38 PM phipli: Tom_L, also, soldered some 0402 resistors today
05:38 PM phipli: on a practice board
05:38 PM phipli: to see if I could
05:38 PM phipli: turns out I can
05:38 PM JT-Shop: I'd have to use a microscope lol
05:39 PM Tom_L: i tried some but found the size difference is hardly worth it in the extra time it takes to align them
05:39 PM phipli: thankfully my near sight is still good :)
05:39 PM phipli: Tom_L, yeah - I think it makes sense for machines, but I still need to get the iron in there
05:39 PM phipli: so it doesn't make much difference
05:39 PM Tom_L: i cheat and have a binocular scope
05:40 PM andypugh: Tom_L: No, I have not gone so far as to stalk the guy.
05:40 PM gloops: http://www.aapcb.com/media/images/Miniturization-2.width-640.jpg
05:41 PM gloops: how many 0402s can you fit on a match head
05:41 PM phipli: lol. 01005
05:41 PM Tom_L: don't sneeze while counting
05:41 PM phipli: the 0805 looks huge!
05:41 PM andypugh: Oh, I thought you meant imperail 0402 not metric 0402
05:41 PM Tom_L: same here
05:41 PM phipli: yeah, a 0402 pinged out of my tweezers
05:42 PM phipli: (I meant imperial)
05:42 PM Tom_L: the main reason i went with bigger ones is the small ones got sucked up in my needle suction thingie
05:42 PM andypugh: Well, for your next challenge, 0402 metric
05:42 PM phipli: I wasn't going to bother looking for it, but it just happened to be where I looked
05:42 PM gloops: i lose screwdrivers on my garage floor i dont think a resistor would ever be seen again
05:42 PM phipli: how big are they? 0.4x0.2mm?
05:43 PM phipli: gloops, it landed really close on my desk - must have gone high, not far
05:43 PM andypugh: Where my sister works they changed workshops. The workshop was about 3x3m. They got £2000 to share when they put the carpet in for scrap.
05:44 PM phipli: andypugh, I'd need new tweezers - if the length is half the width of these...
05:44 PM Tom_L: i got mine from dx
05:44 PM andypugh: (It is a goldworking workshop)
05:44 PM Tom_L: i recall something about that
05:45 PM andypugh: I bought a suction thingy. It is utterly and comletly non-funtional. Typical Chinaco, clearly never been tested since they made the forst protoype.
05:45 PM Tom_L: made mine from a reverse fishtank pump and a hypo needle flattened off
05:45 PM phipli: andypugh, I got one of them, but haven't tested it
05:45 PM Tom_L: with a Tee in the line
05:45 PM phipli: thanks for the warning :)
05:46 PM andypugh: This one. The other reviewer seems happy, though: https://www.ebay.co.uk/p/3x-vacuum-SMD-Pump-Suction-Vacuum-Tweezer-Pick-up-Silver-White-BL-K2j4/1294676921?iid=282725264030&_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D43782%26meid%3D49a4502542564ca080ab8b642e8043cb%26pid%3D100005%26rk%3D5%26rkt%3D6%26sd%3D253147365554%26itm%3D282725264030&_trksid=p2047675.c100005.m1851#UserReviews
05:47 PM andypugh: I might add an aquarium pump to mine, it’s a nice handle and selection of suction cups for the price.
05:47 PM Tom_L: the fishtank pump has enough suction to hold a 32pin tqfp on the end of a needle ok if you pick it up nice n square
05:48 PM Tom_L: i just hotglued a fitting on the bottom
05:48 PM Tom_L: or backend.. i forget which
05:49 PM Tom_L: that and some aquarium tubing and tee to relieve the suction
05:50 PM phipli: hum...
05:50 PM phipli: you could do the same thing with a passive picking up tool
05:50 PM phipli: if you pressurised the room instead
05:51 PM phipli: would mean you could make it quite small
05:51 PM phipli: it wouldn't need any moving parts...
05:51 PM phipli: sounds like a plan
05:54 PM Tom_L: http://www.dx.com/p/weitus-stainless-steel-precision-straight-angled-tweezers-black-137918#.Wqmn57UViHs
05:54 PM Tom_L: i got a few of those in various shapes
05:55 PM phipli: I've been using a pair that are basically like the smallest of those three
05:55 PM phipli: came in a screwdriver set for an unknown reason, and are better than my previous pair
05:56 PM Tom_L: for holding the tiny screws the screwdrivers fit :)
05:57 PM phipli: heh
06:00 PM phipli: https://www.youtube.com/watch?v=pCteBhr4dGY
06:01 PM Tom_L: buddy of mine used to race mazdas
06:02 PM phipli: When I was doing a course in Rugby, there was an RX7 that drove past every morning
06:02 PM phipli: you could smell it approaching - smelt great
06:03 PM phipli: not sure what oil they were using, but it smelt a bit like Castrol R
06:04 PM phipli: LOL - someone talking about Castrol R :
06:04 PM phipli: "I've got a bottle of it somewhere in the garage that I occasionally used to mix with the petrol on my old 2 stroke bike. Trouble was, the lovely smell was always behind me so I could never appreciate it. Thankfully I found a solution; stick it in the lawnmower! Cutting the grass became a pleasure with the combined smell of Castrol R and freshly cut grass!"
06:06 PM Tom_L: i overhauled a jensen healey transmission once that came full of whale oil
06:06 PM Tom_L: not so pleasant
06:09 PM JT-Shop: Steven Hawkins died, longest lived to have ALS
06:09 PM SpeedEvil: https://imgur.com/gallery/TjwKD Do you even lift?
06:10 PM phipli: JT-Shop, yeah - he did well. Was in his 70s. Considering he wasn't expected to see out his 20s
06:11 PM JT-Shop: aye
06:11 PM JT-Shop: 76 I think
06:11 PM JT-Shop: he had 3 children too
06:12 PM Tom_L: sheldon will be sad
06:12 PM JT-Shop: lol you watch that too?
06:12 PM Tom_L: sometimes, she does all the time
06:13 PM Tom_L: i kinda like young sheldon though
06:13 PM JT-Shop: I've never watched that one
06:13 PM Tom_L: you should
06:14 PM Tom_L: find it from the first episode online
06:14 PM phipli: :)
06:14 PM Tom_L: you may fall outta your chair on the first episode
06:14 PM phipli: I've only ever watched one episode... the missus says I should watch more
06:15 PM Tom_L: if i'm too tired to do anything else i'll watch it
06:16 PM Tom_L: https://www.cbs.com/shows/young-sheldon/video/209AD28E-C74B-7E32-5573-AB531AF55CE2/young-sheldon-pilot/
06:21 PM phipli: Right. I'm off folks
06:21 PM phipli: night
06:22 PM Tom_L: later
06:39 PM BeachBumPete: Ooh nice bigass Bacon Cheeseburguesa ;)
07:31 PM gregcnc_: see through wankel https://youtu.be/pCteBhr4dGY
08:29 PM enleth: jeez, I hate bearings pushed into blind holes
08:32 PM enleth: there is this small gear in a Bridgeport's backgear mechanism, the one between the motor and the spindle, that transfers the torque in low gear
08:32 PM enleth: it sits on a short shaft that's somehow held in a bearing that sits in a blind recess in the casting
08:33 PM enleth: the damn thing is almost completely surrounded by casting, nowhere to grab onto it with a gear puller or anything
08:35 PM enleth: the only way of getting it out of there that I can think of is to drill a hole through the back of that casting and either force the damn thing out of there with a pin and a hammer, or tap the hole and use grease or oil as a hydraulic fluid
08:35 PM enleth: to push it out of there using a piston pump
08:35 PM enleth: of course, the latter would only work if the bearing is sealed
08:36 PM enleth: if it's not, it will just let the hydraulic fluid right through
08:51 PM enleth: eh, so videos on yt suggest that this shaft just pops out of there
08:51 PM enleth: yeah, right
08:55 PM enleth: OK, there's supposed to be enough space under that bearing to use an inertial bearing extractor on it
08:55 PM enleth: still, it stinks
08:57 PM enleth: oh, and the bull gear assembly
08:58 PM enleth: https://youtu.be/rmH-0qmQVhQ?t=36s see that cutout in the outer sleeve that provides access to the locknut?
08:58 PM enleth: well, on the CNC version, the sleeve is solid
08:59 PM enleth: so instead of a hook wrench and/or a brass punch, I need some kind of a giant notched pipe wrench thing to get in there
08:59 PM enleth: absolutely insane
09:00 PM andypugh: Pipe, drill two holes, two pegs.
09:00 PM andypugh: You don’t need a full set of pegs (probably)
09:01 PM Tom_L: working on my lcnc post a bit. got fixture offsets added to it now
09:02 PM enleth: andypugh: more like grind two notches, weld two pins - there's no space around that locknut for a pipe, it needs to fit axially
09:02 PM enleth: andypugh: I need to find a piece of pipe just the right diameter first
09:03 PM enleth: over the last couple days I did find out that the CNC bridgeport head is generally an absolute pain in the ass to maintain
09:03 PM andypugh: Lathe?
09:03 PM enleth: you really, really want to keep it well lubricated and not in any need of service, because if it is in need of service, you're in for a baaaaad time
09:04 PM Tom_L: heh
09:04 PM enleth: andypugh: funny that you mention it, I am going to have a lathe big enough for this over here in a couple days
09:04 PM enleth: I don't have *stock* big enough, though
09:04 PM enleth: because I had no lathe to chuck it
09:06 PM enleth: anyway, the way this whole head assembly is bolted together, the way things go through the castings, the way all the moving parts join, the way wiring is pulled - it all makes it so replacing just about anything, or even getting access for proper cleaning, requires an almost complete disassembly of the whole head
09:06 PM enleth: and this involves several operations that require the skills of a contortionist acrobat
09:08 PM enleth: the whole thing *works* very well
09:09 PM enleth: but it's definitely the most annoying part of the mill to maintain
09:13 PM Cromaglious_: ARGH Mint 18 is causing me so many problems ./configure uspace fails right off the bat.
09:16 PM andypugh: enleth: Or, as a friend used to say “The skills of an amateur gynæcologist”
09:17 PM enleth: it's too deep in there to apply any kind of torque with a punch
09:18 PM enleth: the damn nut
09:18 PM enleth: pipe it is, eurgh
09:20 PM enleth: why didn't they use the same sleeve with a cutout on this model?
09:22 PM andypugh: Stiffness?
