01:16 AM archivist: Tom_L, you might want to revue where your vertical rails/slides will be, limited vertical movement
01:23 AM archivist: review even
01:31 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_base_XAxis3.jpg
01:31 AM Tom_L: the plan
01:31 AM Tom_L: i can raise them up if need be
01:33 AM archivist: if the rails are on the rear column you can get down to base
01:33 AM Tom_L: limits Y travel though
01:33 AM archivist: just above y
01:34 AM Tom_L: with the table in as it is, i get about 9"
01:34 AM archivist: from my self build, height/travel was a problem
01:34 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_base_XAxis1.jpg
01:36 AM Tom_L: with a vise, i have clearance problems on the sherline right now
01:37 AM archivist: I had to jack the column and add rotational stiffness http://www.collection.archivist.info/archive/DJCPD/PD/2009/2009_07_10_cnc_with_LCD_P4/IMG_0268.JPG
01:37 AM Tom_L: i think this should give clearance
01:37 AM archivist: heiaght was worse for me due to the rotaries as well
01:37 AM Tom_L: yeah
01:38 AM Tom_L: i'm not planning for a rotary
01:38 AM Tom_L: or it would require quite a bit more
01:38 AM Tom_L: pic loading very slow
01:40 AM IchGucksLive: good morning from germany
01:40 AM Tom_L: good night from US
01:41 AM MarcelineVQ: hmm, having travel on the column would allow you to goosneck for clearance https://imgur.com/a/3gySB
01:42 AM IchGucksLive: Tom_L: the mill drawing is very wide clarence
01:42 AM XXCoder: uh that looks weirdly formed
01:42 AM IchGucksLive: tool force will effect the frame stracture
01:43 AM MarcelineVQ: XXCoder: it's just a little warp for an example of where clearance can be gained
01:44 AM XXCoder: ahh ok
01:44 AM MarcelineVQ: probably not really an issue on a machine this size though, you could turn the part around pretty quickly
01:45 AM Tom_L: i'll read up tomorrow, gnite
02:20 AM gloops: first day im up after 6 - car boot sale day...
02:21 AM MarcelineVQ: gonna snag some goodies?
02:21 AM gloops: i might, its late now, you want to be there when its still dark really
02:22 AM gloops: the tool hunters are very keen - likely any real treasures will be gone already
02:29 AM * archivist thrashes up the motorway and snags all the tools
02:31 AM gloops: there was actually an old clockwork movement last week archivist, i thought of you when i looked at it, looked like it was out of a music machine, had some interesting gears and this thing that spun round with little cups on it
02:32 AM gloops: it worked, like all turned when you moved it, i might get it if its still there
02:33 AM archivist: cups! 400 day clock dont touch with a barge pole
02:33 AM archivist: they hang on a wire and rotate?
02:33 AM gloops: it was old, bloke is there every week
02:34 AM MarcelineVQ: idk, sounds pretty great, think of how much work you could get done with a 400 day year
02:34 AM archivist: it is how long the wind up lasts
02:34 AM gloops: nah this was deffo out of a small music player, what do you call them - where the pins pull punched paper through
02:34 AM archivist: a music box
02:35 AM gloops: some gears were about 3 inch accross, different types of gears, cut at angles and so on, charming thing
02:36 AM archivist: but where is the rest especially the case and tuning forks
02:36 AM gloops: gone
02:36 AM gloops: he wanted 5 quid i offered him 3 and walked off, didnt shout me back
02:37 AM archivist: cups are on the governor for that sort of mechanism
02:38 AM archivist: last one I repaired http://www.collection.archivist.info/searchv13.php?searchstr=music+pd
02:39 AM archivist: came from another clockmaker for me to make the completely missing gear
02:40 AM gloops: hmm, i thought it would be some kind of regulator or balancing thing
02:40 AM archivist: only sent the parts I would need
02:40 AM archivist: cups are regulating the speed
02:40 AM gloops: ill get it if hes there, for my own curiousity, wife will love me
02:41 AM archivist: they fly out and grab more air
02:41 AM gloops: crossed my mind the gears might make something, but i wouldnt want to take it to bits
02:42 AM archivist: note very similar to record player mechanism speed control
02:42 AM gloops: ahh yeah i think they do have some movement yeah
02:43 AM archivist: you will spot the shaft on a record player mech
02:43 AM MarcelineVQ: I want one that does this tune https://www.youtube.com/watch?v=UoPUAKrZL7g
02:43 AM gloops: im going anyway
03:02 AM Deejay: moin
04:13 AM jthornton: morning
04:14 AM Deejay: hey
04:14 AM XXCoder: heys
04:15 AM jthornton: well the RPi3 chicken controller has the right time this morning
04:16 AM jthornton: 69F
04:16 AM XXCoder: cool
04:17 AM jthornton: warmer than yesterday afternoon
04:17 AM XXCoder: 41f here
04:17 AM XXCoder: yeserday we had snow. first time since 1925
04:17 AM XXCoder: for nov that is
04:17 AM jthornton: we are supposed to get to 41f tuesday night
04:19 AM XXCoder: i forgot which el nino ot other one, its causing weather to be cold in some areas in usa
04:33 AM XXCoder: (title of book you're reading) with a chainsaw
04:33 AM XXCoder: mines necromancer with a chainsaw :P
04:34 AM XXCoder: last book would be much more fun - the dreeson incident with a chainsaw
04:46 AM jthornton: damn firefox is excruciating slow today
04:53 AM XXCoder: yeah?
04:55 AM jthornton: top shows it using 95% of CPU
04:55 AM XXCoder: dang
04:55 AM jthornton: and 51% of memory
04:56 AM archivist: jthornton, some websites have terrible javascript on them causing it
04:56 AM archivist: often sneaks in on the adverts
04:57 AM gloops: i get this when chip fan/heatsink are getting fluffed up
04:59 AM archivist: didnt spend enough tome at flea market error
04:59 AM gloops: not that i know anything about why that would cause such problems, just that it happens to me
04:59 AM archivist: hot processor just invokes a slow down to cool
04:59 AM jthornton: watching the cpu in top to see if I can finger out what the offending page was
05:00 AM gloops: nothing on the boot sale archivist, got the bolts i wanted though, some drill bits and clamps
05:01 AM gloops: bag of 5 inch m12 bolts - half the length has been squared off, just the job i though
05:01 AM gloops: but not enough nuts for what i want
05:02 AM archivist: retrofit https://www.ebay.co.uk/itm/MITUTOYO-BH-305-Coordinate-Measuring-Machine/192343194877
05:02 AM archivist: bit expensive
05:03 AM gloops: anything over 9.99 is expensive
05:03 AM gloops: but its only money, what else what you do with it
05:04 AM archivist: more educational than beer
05:05 AM gloops: some blokes buy alloy wheels
05:05 AM archivist: strange
05:05 AM gloops: bbiab
05:28 AM monkeyisl: yo, how is linuxcnc differ from mach3~4?
05:28 AM XXCoder: mach is crappy cnc controller and linuxcnc is far better and open source.
05:33 AM archivist: linuxcnc 9 axis, more configurable
05:33 AM archivist: can drive analogue servos with feedback
05:36 AM monkeyisl: should i just a parallel port or motion board?
05:36 AM jthornton: linuxcnc works
05:36 AM monkeyisl: have*
05:37 AM makerman: morning
05:38 AM archivist: monkeyisl, motion is in linuxcnc whether parallel or fpga
05:40 AM monkeyisl: archivist : ahh ok.. but hw motion isn't needed at all? i'm buildng up to 4 axix. 5+ is beyond my concern..
05:41 AM monkeyisl: no jitter or performance problem ?
05:41 AM XXCoder: that depends on computer'
05:41 AM XXCoder: if your computer have say 100,000 jitter it might work on slow speeds
05:41 AM archivist: use an fpga to reduce the pc needs
05:41 AM XXCoder: but better is 25k-50k
05:41 AM monkeyisl: spindle is 2.2K from china
05:42 AM archivist: plenty use those spindles
05:42 AM monkeyisl: archivist : fpga is like ,, you can say any popular boards?
05:42 AM archivist: mesa
05:43 AM jthornton: mesaus.com
05:44 AM jthornton: disclaimer that is my store, I'm a Mesa distributer
05:51 AM archivist: monkeyisl, what are you going to be making
05:53 AM monkeyisl: cnc 3axis mainy, but will be ended up with adding +1 axis. ..bed will be like 370x500 , mainly for aluminium milling..etc..
05:54 AM XXCoder: linuxcnc will do just fine
05:54 AM XXCoder: adding axis is little more than just adding data and configuring stuff
05:54 AM XXCoder: just make sure there is few pins left on parallel for interfacing with new axis later
05:55 AM gloops: well, on an old PC that cost £20, linuxcnc moves my router at 13500mm/m without issues
05:55 AM gloops: or should i say - no software issues heh
05:55 AM XXCoder: gloops: what was that pc latency was
05:56 AM gloops: XXCoder im not sure didnt due any proper testing, i had it entered at 30k
05:56 AM XXCoder: lol ok
05:57 AM gloops: dont even know the specs of the computer, its an old XP era, i put 4 gig ram in
05:57 AM XXCoder: latency is bit hard to predict
05:57 AM XXCoder: my linuxcnc pc is 10 years old now
05:57 AM XXCoder: 15k latency
05:57 AM XXCoder: it actually tested to less than that but I prefer over than under
05:58 AM gloops: once i got over 20000mm the motors starting losing steps
05:58 AM XXCoder: I wonder if tis combined limit or per axis limit
05:58 AM gloops: i think quick tests showed 25-30k, a few minutes
05:58 AM XXCoder: say if x and y is moving at 15k mm/m and combined it loses steps
05:59 AM gloops: it was accelerating mainly
05:59 AM gloops: when it lost steps
05:59 AM XXCoder: well if it works it works :)
05:59 AM gloops: i get latency errors when trying really fast like 40000mm
06:00 AM XXCoder: mine cant go too far over 10k mm/m
06:00 AM XXCoder: not because of latency but because of fairly crappy steppers
06:00 AM XXCoder: it was worse at 5k with old tb6560
06:01 AM gloops: i posted a short vid a while back showing 13500mm - no problems no errors, not got the url
06:03 AM XXCoder: laters going to bed
06:03 AM gloops: ive got some of those copied smoothstepper drivers
06:03 AM XXCoder: time change is going to suck :(
06:03 AM gloops: gnight
06:03 AM jthornton: nite
06:03 AM slipalong: Anyone see this message when setting up home/limit switches? "end of move in home state 7"
06:03 AM XXCoder: I would finish at what was 2:45 am but now 1:45 am
06:03 AM XXCoder: anyway laters
06:03 AM gloops: well im confident enough with linuxcnc anyway to invest in a better build, hoping to get the hardware good for 250 ipm cutting
06:04 AM gloops: no doubt at all linuxcnc will provide the signals
06:07 AM jthornton: https://www.youtube.com/watch?v=mEk-Es2sjRU
06:08 AM jthornton: guy builds a chicken coop with a biscuit joinery must think it is furniture lol
06:08 AM archivist: took me a couple of days, found my little angle dekkor
06:08 AM jthornton: slipalong: does the home move fail?
06:09 AM jthornton: might be sitting on the switch at the end of the home sequence
06:11 AM archivist: may need to move the switch or something and try again
06:17 AM monkeyisl: could i use pi -- ethernet interface -- fpga -- stepper ?
06:18 AM archivist: pi is a bit tight/slow
06:22 AM monkeyisl: archivist : what interface would be teh best for fpga interface from pc?
06:23 AM archivist: pci or ethernet
06:23 AM jthornton: https://mesaus.com/index.php?route=product/product&path=66&product_id=66
06:23 AM jthornton: https://mesaus.com/index.php?route=product/product&path=69&product_id=78
06:24 AM jthornton: https://mesaus.com/index.php?route=product/product&path=69&product_id=86
06:24 AM archivist: disclaimer I dont have any so not biased :)
06:25 AM phipli: jthornton, how strong are biscuit joints?
06:25 AM phipli: do they go soggy and fall to bits when you spill tea on them?
06:25 AM jthornton: not as strong as pocket screws
06:25 AM jthornton: yea
06:26 AM jthornton: I built mine with pocket screws
06:26 AM jthornton: biscuit joinery is for table tops lol
06:27 AM jthornton: I think today is time to put the RPi3 in control of the chicken coop
06:27 AM monkeyisl: <jthornton> https://mesaus.com/index.php?route=product/product&path=69&product_id=86 <-- looks most advacned lol even isolated. cool
06:27 AM phipli: I'll stick an SBC out with ours as soon as I find a USB infrared camera
06:28 AM phipli: should get some waterproof ethernet bulkhead connectors in the next few days for that project
06:28 AM jthornton: cool
06:29 AM jthornton: I need to run my lan cable in a more permanent fashion than across the floor and under the door
06:29 AM phipli: If I was paranoid, I should probably stick that outside ethernet cable on some kind of DMZ though
06:29 AM jthornton: DMZ?
06:29 AM phipli: De-militarised Zone
06:29 AM phipli: an isolated area of your network that can't access anything else
06:30 AM phipli: usually basically the other side of the firewall (outside)
06:30 AM jthornton: how do you isolate it?
06:30 AM phipli: with a good router
06:30 AM phipli: or a linux based router
06:30 AM phipli: you can flash custom linux based firmware to a lot of home routers
06:31 AM jthornton: hmm mine is a D-Link DIR-632
06:31 AM phipli: like OpenWRT
06:31 AM monkeyisl: https://mesaus.com/index.php?route=product/product&path=69&product_id=86 <--- do you have any PDF for this?
06:31 AM monkeyisl: so i can dream my stuff before submit order
06:31 AM phipli: jthornton, https://wiki.openwrt.org/toh/d-link/dir-632
06:31 AM jthornton: the manual is linked below
06:32 AM phipli: jthornton, still in beta on that device
06:32 AM jthornton: or not
06:32 AM phipli: but give a lot more flexibility than default firmware on most home routers
06:32 AM phipli: you can also use crontab etc to run lightweight tasks on it
06:32 AM phipli: kind of handy
06:33 AM phipli: don't have one set up at the moment, but I have an old d-link flashed with OpenWRT
06:35 AM phipli: jthornton, regarding that henhose - he had the sense to make the coop floor "lip free" to the outside so he can scrape the mess out
06:39 AM jthornton: monkeyisl: refresh the page and select the Support Materials tab
06:39 AM phipli: jthornton, https://www.youtube.com/watch?v=5PEEfpc_YKI
06:41 AM jthornton: interesting but not very practical I'd think
06:41 AM phipli: yeah, they'd never get off the ground
06:42 AM monkeyisl: jthornton : firmware parameters are fully custimzedable for any machine?
06:42 AM monkeyisl: i mean motion feed etcetc,,,.e
06:43 AM monkeyisl: jthornton : ethernet or db25 what u recommend? lo
06:47 AM monkeyisl: i mean ethernet latency won't be ignorable? or.. i'm worrying too much?..
06:48 AM jthornton: yes the configuration settings can be set for everything you want
06:53 AM jthornton: pci/pcie is easy to get up and going using the wheezy iso http://linuxcnc.org/docs/2.7/html/getting-started/getting-linuxcnc.html#_download_the_image
06:54 AM monkeyisl: OK
06:54 AM jthornton: phipli: https://www.backyardchickens.com/articles/a-chicken-coop-that-is-out-of-this-world.73235/
06:54 AM jthornton: the write up on the ufo coop
06:55 AM monkeyisl: jthornton
06:55 AM monkeyisl: is there any configuration file?
06:55 AM monkeyisl: one flie setup or.. any software can config my cahine
06:55 AM monkeyisl: machine.
07:16 AM jthornton: pncconf can make a configuration for Mesa cards
07:17 AM archivist: monkeyisl, there are a couple of config programs plus you can edit the files
07:17 AM archivist: the config programs only go so far for standard situations
07:18 AM jthornton: phipli: http://paste.ubuntu.com/25894653/ the python code for the coop, pretty simple and makes a web page to show status
07:30 AM monkeyisl: what pcie pc is best sutiable in 2017?.. sry.. but you guys already have expereinced .. i'm looking for compact ..
07:35 AM jthornton: I can look at some of the mother boards I have when I go to the shop in a bit
07:36 AM monkeyisl: lol cool OK
07:36 AM monkeyisl: please beep when you're ok
07:40 AM jthornton: I don't beep I chirp
07:46 AM monkeyisl: add ardunio buzzer
07:53 AM monkeyisl: fi ound one @ google ga-e350n-usb3
08:18 AM jthornton: yea got all the build dependencies satisfied before free time is over
08:18 AM monkeyisl: ASRock J4205-ITX is my choice
08:18 AM monkeyisl: quad core
08:35 AM JT-Shop: H81M-S2H GSM latency about 25us
08:54 AM IchGucksLive: hi
08:54 AM IchGucksLive: monkeyisl: still online ?
08:54 AM hazzy: hello Ich
08:55 AM IchGucksLive: ;-)
08:55 AM monkeyisl: IchGucksLive : hi
08:55 AM monkeyisl: sup
08:55 AM jym: Ok, FINALLY FINALLY FINALLY found a use for 3D printer... https://www.youtube.com/watch?v=NMeODpNg_k8
08:56 AM IchGucksLive: monkeyisl: if you want to go as little as you can you can look for J1800 /1900 od a old but realy fast D535mw
09:00 AM jym: D535 is REALLY old by today's standard, what I have is ancient
09:01 AM * jym slams some 386SX25 CPU's on the table
09:02 AM IchGucksLive: D525Mw Sorry
09:02 AM monkeyisl: Intel® Quad-Core Pentium® Processor J4205 (up to 2.6 GHz)
09:03 AM monkeyisl: IchGucksLive : i have this J4205-ITX on my newegg cart.
09:03 AM monkeyisl: 4gb memory is more than enough? or
09:03 AM monkeyisl: better have 8gb?
09:05 AM IchGucksLive: no 2Gb is ok
09:06 AM monkeyisl: :D
09:06 AM IchGucksLive: monkeyisl: where in the world are you
09:06 AM IchGucksLive: monkeyisl: my youtube chanel for info https://www.youtube.com/channel/UCmwhCL92ZQRSVqFe3jGwJSQ/videos
09:07 AM IchGucksLive: monkeyisl: im in germany
09:08 AM IchGucksLive: monkeyisl: is there already a mashine or is it to be build
09:08 AM monkeyisl: IchGucksLive going to build i bought LM, spindle.
09:09 AM IchGucksLive: what size on plan
09:09 AM IchGucksLive: workarea
09:10 AM monkeyisl: 370x500
09:11 AM IchGucksLive: thats a good size
09:11 AM IchGucksLive: do you already got a budget or maybe rail parts
09:11 AM IchGucksLive: like HIWIN or SBR
09:12 AM IchGucksLive: are you in the USA
09:14 AM monkeyisl: i'm near by china.
09:14 AM IchGucksLive: Asia
09:14 AM IchGucksLive: so it is cheep parts
09:14 AM IchGucksLive: lots of cnc in the philipines
09:14 AM monkeyisl: i bought used, it's the part from real machine so.. cna't tell it's cheap.
09:15 AM IchGucksLive: are you retrofitting a Real mashine
09:16 AM IchGucksLive: that means you are doing a new electronic and control on top a a old mashine
09:17 AM monkeyisl: rkd514 l-a used stepper driver.
09:17 AM IchGucksLive: there are cheep sets just to be connected to a linuxcnc controler http://stores.ebay.com/Rattmmotor/CNC-Controller-kit-/_i.html?_fsub=8014442011
09:19 AM monkeyisl: IchGucksLive : https://tech.thk.com/en/products/thk_cat_main_five.php?id=3672
09:20 AM IchGucksLive: monkeyisl: here are the sets for LM http://stores.ebay.com/Rattmmotor/Linear-bearing-slide-block-/_i.html?_fsub=8139308011
09:22 AM IchGucksLive: ok im off later
09:23 AM monkeyisl: IchGucksLive : nice ballscrew
09:23 AM monkeyisl: IchGucksLive PK566A motor.
09:25 AM monkeyisl: IchGucksLive : thanks for info. btw.. i've already set stpper, controller, lm, spindle,
09:27 AM monkeyisl: https://imgur.com/a/mSra7
09:27 AM monkeyisl: too bad i can't understand geramn langauge.
09:29 AM alfepu: hola hay alguien que sepa instalar linuxcnc en ubuntu17.10
09:30 AM TurBoss: hola
09:31 AM TurBoss: solo en modo simulador
09:31 AM alfepu: no se puede entonces?
09:31 AM alfepu: me explico
09:31 AM TurBoss: linuxcnc requieres de un nucleo (linux-kernel) de tiempo real
09:31 AM TurBoss: *requiere
09:32 AM alfepu: tengo un laser cutter que he comprado en los chinos y he logrado que funcione pero con gcodesender y mi idea es utilizar solo sofware libre
09:32 AM alfepu: ufff
09:33 AM TurBoss: necesitaras un pc dedicado y la distribucion de linuxcnc 2.7
09:33 AM TurBoss: este viene configurado
09:34 AM TurBoss: http://www.linuxcnc.org/linuxcnc-2.7-wheezy.iso
09:34 AM alfepu: si yo logro instalar debian y hay si me viene linuxcnc pero yo el que se manejar es ubuntu
09:34 AM TurBoss: es lo mismo
09:34 AM TurBoss: si sabes manejar ubuntu no tendras problemas con debian
09:35 AM alfepu: si con debian no se instalar muchas cosas
09:35 AM TurBoss: la unica diferencia es el gestor de ventanas
09:35 AM alfepu: creo q hay que tener mas formacion
09:35 AM alfepu: o saber manejar mejor la terminal
09:35 AM TurBoss: el gestor de paquetes synaptic es muy util
09:36 AM alfepu: entonces la idea es instalar debian junto a ubuntu
09:36 AM alfepu: noo
09:36 AM alfepu: ?
09:36 AM TurBoss: pues su quieres hacer dual booting
09:36 AM alfepu: ufff eso no se lo que es
09:37 AM TurBoss: yo personalmente buscaria un pc dedicado
09:37 AM TurBoss: eso es que puedes elejir que sistema arranca el pc ubuntu o debian
09:37 AM alfepu: aja
09:37 AM TurBoss: y con dedicado me refiero a que solo tenga debian + linuxcnc
09:37 AM alfepu: si al final eso sera lo que haga
09:37 AM TurBoss: yo uso un pentium 4
09:38 AM TurBoss: con 2 GB de ram
09:38 AM TurBoss: ya ves que no es una maravilla
09:38 AM TurBoss: pero es funcional
09:38 AM TurBoss: asi no tengo ocupado el escritorio mientras trabaja la maquina
09:39 AM monkeyisl: jthornton : you arrived ?
09:39 AM alfepu: si si eso es lo que hare
09:39 AM TurBoss: ok suerte
09:39 AM TurBoss: aki estamos para lo que necesites
09:40 AM alfepu: muchas gracias
09:40 AM TurBoss: pero es recomendable hablar en ingles asi otros pueden ayudar tmb
09:40 AM TurBoss: :D
09:40 AM alfepu: es la primera vez que utilizo chat jejej
09:40 AM alfepu: ufff pues el caso es que estoy en alemania
09:40 AM alfepu: aprendiendo el idioma porque tube que emigrar
09:40 AM TurBoss: :)
09:41 AM alfepu: asin que ingles sera el proximo para no hacerme muchos lios
09:41 AM TurBoss: ja
09:41 AM TurBoss: da
09:41 AM alfepu: q no veas con el aleman
09:42 AM alfepu: ja
09:42 AM TurBoss: tela
09:42 AM alfepu: tela tela tela
09:42 AM TurBoss: lo que no se es como se pronuncian 4 consonantes seguidas jajajaj
09:42 AM alfepu: llevo aqui mas de un aöo y aun no he aprendido
09:42 AM alfepu: jejeje
09:43 AM alfepu: pues no pronuncias las cuatro simplemente haces un sonido donde al pareces estan las cuatro
09:43 AM alfepu: entschuldingung
09:44 AM TurBoss: :D
09:44 AM TurBoss: por aqui hay alemanes tmb
09:44 AM alfepu: se pronuncia entchuldingun
09:44 AM alfepu: pues de lujo haber si me enseöan algo porque no pillo na
09:44 AM TurBoss: vaya
09:46 AM alfepu: bueno pues voy a ver si me descargo la imagen para ir probando a debian
09:47 AM TurBoss: ok
09:47 AM TurBoss: no rompas nada
09:47 AM alfepu: jejeej
09:47 AM alfepu: se intentara
09:59 AM alfepu: TurBoss esta por hay
10:00 AM TurBoss: alfepu: yes
10:01 AM alfepu: otra pregunta
10:01 AM alfepu: tengo ubuntu instalado y me gustaria instalar debian en una particion
10:01 AM TurBoss: si
10:01 AM TurBoss: pues la verdad
10:01 AM TurBoss: nose
10:01 AM TurBoss: :D
10:02 AM TurBoss: yo tengo varios discos duros
10:02 AM TurBoss: asi no hago particione
10:02 AM TurBoss: s
10:02 AM alfepu: lo que pasa es que no se como hacer para que al arrancar el pc me diga cual sistema abrir
10:03 AM alfepu: ya que antes siempre habria en debian
10:03 AM phipli: jthornton, how does it do the web interface? Draws an image to a hosted location?
10:04 AM JT-Shop: phipli: it is only a static web page updated each minute so it just writes the text to a .html file in www/var
10:05 AM TurBoss: alfepu: si tienes un disco duro de sobra meteselo e instala debian ahi luego en la pantalla de inicio de la bios de tu pc pulsas f8 o f12 nose para seleccionar el discoduro que deseas arrancar
10:05 AM TurBoss: asi no tocas el disco duro de ubuntu
10:05 AM TurBoss: de hecho yo hasta lo desconectaria durante la instalacion de linuxcnc
10:05 AM alfepu: pues no tengo un disco duro crees que en un pendrive funcionaria
10:06 AM TurBoss: si
10:06 AM TurBoss: no
10:06 AM TurBoss: o si
10:06 AM JT-Shop: phipli: https://imagebin.ca/v/3gGA0ipdoRsj
10:06 AM TurBoss: ....
10:07 AM TurBoss: linuxcnc es livecd tmb
10:07 AM alfepu: y en debian ya vendria instalado linuxcnc nooo
10:07 AM TurBoss: puedes meterlo en un pen
10:07 AM TurBoss: en el link que te pase si
10:07 AM alfepu: vale voy a probar
10:07 AM TurBoss: ok
10:08 AM alfepu: en debian ya viene instalado linuxcnc verdad
10:08 AM alfepu: o habria que instalarlo
10:08 AM archivist: JT-Shop, opto to count the buggers in and out
10:08 AM TurBoss: alfepu: http://linuxcnc.org/docs/2.7/html/getting-started/getting-linuxcnc.html
10:09 AM alfepu: ok danke
10:09 AM alfepu: jeje
10:09 AM alfepu: ok gracias
10:09 AM TurBoss: es muy importante pasar el "latency test"
10:09 AM TurBoss: para ver si el pc da la talla
10:09 AM alfepu: y como lo hago
10:10 AM phipli: JT-Shop, have you ever heard of Flask?
10:10 AM TurBoss: una vez arranques el linuxcnc en modo live
10:10 AM phipli: lets you do dynamic webpages in python
10:10 AM TurBoss: hay una herramienta
10:10 AM TurBoss: para ello
10:10 AM phipli: one of my old pet monitoring systems used it
10:10 AM phipli: used to take a photo when someone accessed the webpage
10:11 AM phipli: moved away from it so that I didn't have to expose my home ip
10:11 AM alfepu: aja voy a descargarme la iso
10:11 AM phipli: but within the house, can be handy
10:12 AM phipli: JT-Shop, ordered one of these : http://www.ebay.co.uk/itm/222670199213
10:12 AM phipli: it /should/ do video over USB (webcam style) and also IR
10:12 AM phipli: meaning I can use an IR floodlight
10:19 AM jym: phipli: is it rechargeable?
10:20 AM jym: ah, it is
10:20 AM jym: 2MP
10:20 AM jym: Built-in lithium battery sustainable camera up to 100 minutes.
10:22 AM jym: JT-Shop: $16 https://www.ebay.com/itm/SQ11-Full-HD-1080P-Mini-Car-DV-DVR-Camera-Spy-Hidden-Camcorder-Night-Vision-US/272902162895
10:30 AM phipli: jym - yes, but I'm using it plugged into usb
10:30 AM phipli: so I don't need the battery
10:32 AM jym: wifi cam https://www.ebay.com/itm/Wireless-Spy-Nanny-Cam-WIFI-IP-Pinhole-DIY-Digital-Video-Camera-Mini-Micro-DVR/222673329319
10:34 AM jym: Could use a usb power pack and make that last a long time
10:39 AM jym: Wish the cube had wifi, would be nice for monitoring anywhere
10:43 AM gloops: still a bit more work before i can make sparks - https://postimg.org/image/745hpgzfbv/
10:43 AM jym: surface grinder?
10:43 AM JT-Shop: phipli: no, not heard of flask
10:44 AM archivist: poor lathe!
10:45 AM gloops: quality lathe archivist, this is made in england
10:45 AM archivist: gloops, may need a far more rigid spindle, else spin rate pattern on the work
10:45 AM JT-Shop: https://www.amazon.com/gp/product/B010LH48F4 phipli going to try another ip camera
10:46 AM jym: JT-Shop: I didn't see the beginning of the conversation, what's the camera for?
10:46 AM gloops: archivist i dont really expect a mirror finish lol, in fact i dont expect much at all, i think it will be useful for flattening stuff though
10:47 AM JT-Shop: chicken camera
10:49 AM archivist: bookmark
10:49 AM the_wench: yet another log is at http://emclog.archivist.info/
10:51 AM archivist: gloops, this is miss0rs grinding in a lathe http://picpaste.com/IMG_20171103_190702-YiZKt9lz.jpg
10:52 AM gloops: the cut will be applied under the tension of a trampoline spring, cut lowered by the depth adjustment of the small morticing mounting
10:53 AM gloops: well i have got a big angle plate for milling on the lathe archivist, but limited capacity uo and down
10:53 AM gloops: i.e vice hits jaw bed
10:53 AM gloops: lathe bed
10:54 AM gloops: the old britannias are not for zero tolerance work, but one thing, the headstock and saddle are rock solid
10:57 AM archivist: +- a chalk mark
10:57 AM gloops: haha
10:58 AM gloops: we will see, ill be making some precision rotating ballnuts soon, they will be within a gnats
10:58 AM gloops: i thought my mercer dials had seized up last time i used it
10:59 AM archivist: these used to claim they worked to a chalk mark http://meakinandsonderbyltd.co.uk/
11:00 AM gloops: thats a coating of chalk
11:01 AM gloops: french chalk isnt very thick lol
11:01 AM archivist: they were very good when I used them for bent sheet metal
11:04 AM gloops: maybe using CAD now?
11:05 AM archivist: dunno not used them for 20 years
11:07 AM gloops: magnetic table would be useful
11:07 AM gloops: wonder if 1000 of these 10p chinese micro magnets would do it
11:08 AM archivist: half a dozen nedynium
11:11 AM archivist: I got a knife for a paper cutter ground on a surface grinder and that tought me some about heating and the magnetic force bending it
11:12 AM gloops: there is a link somewhere i found for making a magnetic table, didnt look beyond doable, might have a look later, i wont really need one anyway
11:12 AM gloops: but useful thing to have anyway
11:12 AM gloops: bbl
12:02 PM phipli: JT-Shop, https://projects.raspberrypi.org/en/projects/python-web-server-with-flask
12:03 PM phipli: I've gone off IP cameras after I realised how insecure the first one I bought was
12:04 PM phipli: I couldn't stop it tunnelling back to the manufacturer's site for "easy setup"
12:04 PM phipli: *does not want!*
12:04 PM Tom_L: pi server now?
12:05 PM phipli: That's why I've switched to static images from USB cameras attached to an SBC
12:05 PM phipli: I'm using an Orange Pi atm
12:05 PM phipli: but yeah, small linux board
12:06 PM phipli: It uploads an image to my hosting service every 5 minutes through the day
12:06 PM phipli: saves one per hour as a day summary
12:07 PM phipli: excuse the state of the poor thing (it was attacked by a cat and never fully recovered) but :
12:07 PM phipli: http://elephantandchicken.co.uk/webcam/
12:07 PM phipli: yes, loads of the pictures are black...
12:08 PM phipli: that is why I'm waiting for a IR camera :)
12:08 PM phipli: set the camera up because she sometimes gets herself stuck upside down (wings don't work properly, nor does one leg)
12:08 PM phipli: and we need to go and rescue her
12:09 PM phipli: Should use machine learning to make the computer work out when she's upside down and send me an SMS :)
12:14 PM archivist: local sparrow hawk has then for dinner
12:14 PM IchGucksLive: hi
12:14 PM phipli: http://stuffandnonsense.elephantandchicken.co.uk/?p=195
12:15 PM phipli: I should probably turn comments on to catch any mistakes I've made through feedback...
12:15 PM phipli: but all you get is people with chinese names constantly trying to sign themselves up using russian email addresses.
12:15 PM phipli: modernWorld--
12:16 PM phipli: Evening IchGucksLive
12:16 PM archivist: or a pile of advert/spam type comments
12:17 PM archivist: I turned off the comments on a blog I have
12:17 PM phipli: yeah - got them too
12:17 PM phipli: mixture of people trying to hack me and people trying to sell me stuff
12:17 PM archivist: changed the name of the program too to stop them even attempting
12:17 PM phipli: sometimes both
12:18 PM phipli: I use full blown random passwords on it
12:18 PM JT-Shop: phipli: pretty cool, I would like to do that with a chicken camera
12:18 PM archivist: wordpress--
12:18 PM phipli: archivist, yup, but I don't internet
12:18 PM phipli: I leave that to the missus
12:18 PM phipli: She's the one that knows css and html 5
12:19 PM archivist: you site is doing internet!
12:19 PM phipli: I'm more comfortable in BBC BASIC :)
12:19 PM archivist: I hated the BBC editor
12:19 PM phipli: archivist, wordpress gives me a wordprocessor type thing
12:19 PM phipli: archivist, editor?
12:19 PM phipli: what editor
12:19 PM archivist: on the BBC model B
12:19 PM phipli: just used the command line
12:19 PM archivist: anteeeeq
12:19 PM phipli: if you had an editor you had non-standard software
12:19 PM JT-Shop: but I want do that for an ip camera
12:20 PM phipli: JT-Shop, it should be possible...
12:20 PM phipli: I don't know what software you'd need to use to pull down a frame
12:20 PM JT-Shop: hmm if the RPi3 is in the coop and there are 4 USB ports then a USB camera would work
12:20 PM phipli: but my method is all just python and bash stuff at the command line
12:21 PM phipli: JT-Shop, clone your SD card and give it a go?
12:21 PM phipli: got a web cam lying around?
12:21 PM JT-Shop: somewhere
12:21 PM phipli: you can even use something like a mobile phone as a webcam if you set it to the right mode...
12:21 PM phipli: mine does anyways
12:32 PM JT-Shop: https://stackoverflow.com/questions/9711946/how-to-programmatically-capture-a-webcam-photo
12:34 PM phipli: with usb I just use fswebcam
12:34 PM phipli: fswebcam -r 640x480 ./picture.jpg
12:34 PM phipli: would give you a 640x480 jpg
12:34 PM JT-Shop: can you call that in python?
12:35 PM * JT-Shop starts looking for that webcam
12:35 PM phipli: easier from bash
12:35 PM phipli: but yeah, you can do os calls from python
12:35 PM phipli: would be...
12:35 PM phipli: import os
12:35 PM JT-Shop: ah ok an os call
12:35 PM phipli: then ...
12:36 PM phipli: os.system("fswebcam -r 640x480 picture.jpg")
12:36 PM phipli: you can do it in python directly I think... but I don't have an example to hand
12:38 PM phipli: this opencv example has pulling frames from a live video stream in it :
12:38 PM phipli: https://www.pyimagesearch.com/2015/09/14/ball-tracking-with-opencv/
12:40 PM phipli: back later
12:40 PM phipli: dinner time
12:40 PM JT-Shop: ok
12:42 PM gloops: whats a hobbymat md65 worth?
12:43 PM archivist: nothing, terrible machine
12:43 PM gloops: lol
12:43 PM gloops: not worth cncing?
12:43 PM archivist: spindle is ok, make a milling machine out of it
12:44 PM archivist: the bar bed design is a chatter special
12:44 PM gloops: they seem sought after, selling for more now than when they were new
12:45 PM archivist: I got rid of the bits used the bed and spindle, amateur toy
12:45 PM gloops: https://www.ebay.co.uk/itm/Hobbymat-MD65-metal-lathe-hobby-mat-precision-engineering-metalwork-md-65/122787024225?
12:45 PM archivist: if you use a real machine and then one of them
12:46 PM archivist: hehe "precision"
12:47 PM archivist: you should now recognise the yellow bits of my mill
12:47 PM gloops: i bet that goes well over 100
12:47 PM archivist: we went over to Thetford to fetch it for the old man
12:47 PM gloops: with snapped toolpost
12:48 PM archivist: dad used it little then died so I had it
12:49 PM archivist: the markings on the cross slide are dumb they dont match the screw at all well
12:49 PM gloops: various forum comments dont look too encouraging 'forget thread cutting' lol
12:50 PM archivist: alloy base bendy as fffff
12:50 PM gloops: they go mad for those clarke hobby lathes as well, again more than they originally sold for
12:51 PM archivist: the screws to tighten the tailstock are on the rear where you cannot get at
12:51 PM gloops: you can buy a milling attachment for them both
12:51 PM archivist: 1mm pitch leadscrew is terrible slow to traverse
12:53 PM gloops: https://www.ebay.co.uk/itm/Hobbymat-MD65-metal-lathe-hobby-mat-precision-engineering-metalwork-md-65/322863636580?
12:53 PM archivist: the dovetails on the cross slide were bad too, did some filing and scraping to try and improve
12:53 PM gloops: 400 quid, getting into boxford, harrison myford ml7 range there, and they buy that
12:53 PM archivist: they dont know any better
12:54 PM archivist: boxford will eat it for lunch
12:54 PM gloops: ive seen some nice little boxfords go for under 400
12:54 PM archivist: md65 is plain bad design and not that well made
12:55 PM gloops: still 50 quid, could soon sort tool post out
12:55 PM archivist: I rate the boxfords above myford
12:55 PM gloops: it wont end for that anyway
12:56 PM archivist: I still have a few bits left of it like the leadscrew handle
12:56 PM gloops: ive not used dozens of either but had a few small harrisons and boxfords at a place i worked, they got an ml7 given by some relations, it was not as good anywhere near
12:57 PM archivist: the V bed is inherently better than the flat of a myford
12:59 PM gloops: the foreman was all ' we can get some cracking work out of this' nobody wanted to use the myford though, they waited for the other lathes
12:59 PM gloops: having said that, i wihs i had it lol
01:15 PM gloops: 2 myfords https://www.ebay.co.uk/itm/Myford-ML10-Modelmaker-s-Lathe-x-2-two/272915247514?

03:57 PM MarcelineVQ: that's one word for it
03:58 PM SpeedEvil: It really depends what you want it for.
03:58 PM gloops: well, o further viewing, it is doing it
03:58 PM SpeedEvil: my brother made an excellent surface grinder out of drawer slides and an angle grinder
03:58 PM SpeedEvil: It flattened rough faced tiles to within ~0.1mm or so easily
03:59 PM gloops: yeah, more than one way to skin a cat
03:59 PM SpeedEvil: Which was a good 10* more than was needed.
04:00 PM gloops: that tang is lifting a bit there, have seen a potentially very bad accident with a surface grinder
04:02 PM SpeedEvil: yeah - getting magnetic gap down to ~0 is needed

05:16 PM roycroft: hi folks - do any of you use those 80mm diameter liquid-cooled spindles or similar ones?
05:17 PM roycroft: if so, what do you use for coolant?
05:21 PM Tom_L: why not use antifreze?
05:22 PM phipli: or water?
05:22 PM roycroft: water can get funky
05:22 PM roycroft: that's why i'm asking
05:22 PM Tom_L: antifreze seems to keep it good for quite some time
05:23 PM roycroft: ethylene glycol would probably be fine, as long as the pump i get can handle it
05:23 PM roycroft: i keep my japanese water stones submerged at all times
05:24 PM roycroft: i just dump a teaspoon of borax in the water and that keeps it from getting funky
05:24 PM roycroft: it would probably be easier to use an air cooled spindle
05:25 PM roycroft: but for this application water cooled would work better - i'm going to use it in a router table
05:25 PM roycroft: the spindle end will be sticking up, and sawdust will get sucked down onto the spindle
05:25 PM roycroft: the water cooled ones are sealed, whereas the air cooled ones have fans that would suck in the sawdust
05:26 PM roycroft: air cooled spindles are also noiser than water cooled ones
05:27 PM roycroft: i'm not worried about the thermal efficiency of the coolant
05:27 PM roycroft: i'm worried about having a tank of coolant sitting around for a month or two and not getting funky
05:27 PM roycroft: i'm *not* going to remove the coolant and clean the tank and pump after every use
05:28 PM phipli: I had some stored glycol / water mix go mouldy on me
05:28 PM phipli: not seen that before
05:28 PM roycroft: a lot of the synthetic coolants will get mold or whatever
05:28 PM roycroft: and plan water can as well
05:28 PM roycroft: i've had it happen with plain water
05:29 PM phipli: what ever you do, don't use petrol :)
05:29 PM evilroot: Use an additive made for liquid cooling
05:29 PM roycroft: borax is somewhat alkaline
05:29 PM evilroot: I use Water Wetter for the laser
05:29 PM roycroft: so it might not be good for prolonged contact with stainless steel
05:30 PM evilroot: Its safe for metals
05:30 PM roycroft: the pH of a borax mixture is usally around 8
05:30 PM evilroot: They usually call them "coolant additives" at the auto parts store, and they inhibit bacterial and fungal growth
05:31 PM roycroft: how often do you change the coolant when you add water wetter?
05:32 PM roycroft: and do you just add it to water, or do you use a glycol coolant and add it to that?
05:32 PM phipli: antifreeze is alkaline too
05:34 PM JT-Shop: phipli: got my coop python taking a photo every minute but I need to find night vision usb cameras
05:35 PM roycroft: interesteing
05:36 PM roycroft: ethylene glycol has 1/2 the specific heat of water
05:36 PM roycroft: so while it increases the boiling point and decreases the freezing point of a mix with water, it also reduced the cooling capability of the mixture
05:37 PM phipli: JT-Shop, these things should be : http://www.ebay.co.uk/itm/222670199213
05:37 PM evilroot: Yeah
05:37 PM phipli: "SQ11"
05:38 PM phipli: but I'll tell you for sure when mine arrives
05:38 PM evilroot: I used straight Water Watter and it's been in there a year on the laser
05:38 PM evilroot: With no issues
05:38 PM phipli: says between 17th and 22nd
05:38 PM JT-Shop: ok I'll wait :)
05:38 PM phipli: (delivery)
05:38 PM roycroft: i like that, evilroot
05:38 PM roycroft: simple, easy
05:38 PM phipli: otherwise, if you have a raspberry pi JT-Shop, you could try the official IR camera they do?
05:38 PM phipli: plugs into one of the ribbon connectors
05:38 PM roycroft: this router setup is something that i'll use heavily in bursts, and then it will idle for days or weeks
05:39 PM phipli: JT-Shop, https://www.amazon.com/Raspberry-Pi-NoIR-Camera-Module/dp/B01ER2SMHY/
05:39 PM phipli: more expensive though
05:39 PM JT-Shop: I'm using the I/O for the door and lights
05:40 PM phipli: not that connector
05:40 PM phipli: one of the small ribbon connectors
05:40 PM phipli: just a moment...
05:40 PM JT-Shop: on the side?
05:40 PM phipli: https://cdn-shop.adafruit.com/1200x900/1367-07.jpg
05:41 PM JT-Shop: ah yes that one
05:41 PM phipli: the other similar connector is for a screen
05:41 PM JT-Shop: best to use a usb one so I can position the cameras where needed
05:42 PM phipli: yeah. Cheaper too
05:42 PM JT-Shop: https://www.amazon.com/FlyKasi-Camcorder-Night-Vision-Camera/dp/B071J3XLPK/ref=sr_1_7?ie=UTF8&qid=1509923274&sr=8-7&keywords=SQ11
05:43 PM JT-Shop: not the cheapest but has a mounting bracket :)
05:43 PM phipli: Looks the same as the one I ordered
05:43 PM * JT-Shop better go close the run
05:43 PM phipli: what method did you use to capture the images? The fswebcam one, or the python libraries?
05:44 PM JT-Shop: fswebcam for now
05:44 PM phipli: if you have any issues with weird pictures, it is because the camera doesn't warm up quick enough
05:44 PM phipli: there are solutions
05:44 PM phipli: (I'll have to remind myself)
05:45 PM phipli: basically you can make it take 10 pictures and save the last one
05:45 PM phipli: didn't have an issue with my girlfriend's webcam, but the horrible cheap one my parents gave me sometimes only gave half pictures
05:47 PM JT-Shop: yea sometimes this one is not found but it doesn't have any if lights
05:47 PM JT-Shop: so not much use checking the chickens at night time
05:48 PM Tom_L: JT-Shop, any sign of predators?
05:48 PM JT-Shop: pretty cool that I can put a photo on the web page and I just saw the deck light come on
05:48 PM JT-Shop: none
05:48 PM phipli: did you look at my guide?
05:49 PM JT-Shop: still watching for the one dog that got away... one day it will be back
05:49 PM phipli: or did you do it another way
05:49 PM JT-Shop: yes
05:49 PM phipli: worked ok?
05:49 PM phipli: I've not got anyone to follow it through
05:49 PM JT-Shop: I just did os.system("fswebcam -r 800x600 /var/www/html/coop.jpg")
05:49 PM phipli: ah right
05:49 PM phipli: mine uses sftp to upload to an external site
05:50 PM JT-Shop: pretty cool it shows the date/time on the image
05:50 PM phipli: yeah
05:50 PM phipli: I like that bit
05:50 PM malcom2073: evilroot: You should buy a cheap driver setup, stick linuxcnc on that machine and bet it'll sell for two to three times that price
05:50 PM JT-Shop: that is something I need to look into
05:50 PM phipli: you could also use imagemagik to add extra info if you wanted
05:50 PM JT-Shop: wife asked if we could watch the chickens while in Branson for thanksgiving
05:51 PM phipli: :)
05:51 PM phipli: I'll email you some example code
05:51 PM phipli: do you have sftp on your website?
05:52 PM JT-Shop: I'll have to check
05:52 PM * JT-Shop listens to Thick as a Brick
05:55 PM JT-Shop: yes I have sftp :)
05:58 PM phipli: sent an email
05:58 PM phipli: really basic solution
05:58 PM phipli: you'll need to install a couple of things though possibly
05:59 PM phipli: sshpass
05:59 PM phipli: and ftp - although you might already have them in
05:59 PM * phipli checks how much he put in the actual post
05:59 PM JT-Shop: thanks I'll give that a whirl tomorrw
