01:03 AM gloops_: anyone give an overview of 2 motors one axis, in laymans terms
01:06 AM XXCoder: 2 motors on one axis?
01:06 AM gloops_: seems to be 2 approaches, begin with an extra axis - like xyza, or just start with xyz and duplicate one joint
01:06 AM gloops_: yes 2 on 1
01:06 AM XXCoder: ah yeah
01:06 AM gloops_: i mean an overview of how to set that up in linuxcnc
01:06 AM XXCoder: yeah unfortunately never needed that. maybe someone can evenually.
01:06 AM XXCoder: nows beginning of dead time for chat
01:06 AM XXCoder: only few people
01:07 AM gloops_: yeah, there is a good example in the forum but i dont really understand whats happening with it
01:07 AM gloops_: it isnt sending the same signal to 2 motors i dont think
01:09 AM MarcelineVQ: a quick search brings me to http://linuxcnc.org/docs/2.7/html/hal/hal-examples.html#_connecting_two_outputs there's not much explanation though, and I don't know enough to know if the HAL is where you need to be in the first place
01:12 AM MarcelineVQ: it's not ehe
01:13 AM gloops_: file:///home/gloops/Desktop/How%20to.%202%20or%20more%20motors%20on%20one%20axis.%20Gantry%20LinuxCNC%202.8%20Master%20-%20LinuxCNC.html
01:14 AM gloops_: thats the one ive been looking at, rather long though
01:14 AM gloops_: suppose ill just have to try it in sim
01:15 AM gloops_: want to get it sorted before ive built ths time, i hate having a machine ready and stuck on some software matter
01:15 AM MarcelineVQ: I think stepconf wizard can make an example setup with a doubled up axis if you needed an example to work from
01:17 AM gloops_: hmm not noticed that - it ought to its a common thing now
01:18 AM gloops_: ill change to other drive and have a look
01:25 AM MarcelineVQ: come back gloops :X
01:25 AM MarcelineVQ: gloops: it looks like you can't just pick XXYZ or something, at least with the release version I have, but when picking XYZA the next screen after that there's pin setup so you can set 4 pins to be x dir + x step instead of 2 pins
01:25 AM MarcelineVQ: dunno if that works in that fashion but it could be worth trying
01:25 AM gloops: right thanks will look at that now, that would be easier
01:29 AM gloops: that was way too simple lol
01:30 AM MarcelineVQ: hopefully it does what you're after hehe
01:30 AM gloops: suspect there could be homing issues that but will see
01:30 AM MarcelineVQ: if one motor misses steps and the other doesn't it can be an issue I foresee, but it would be anyway without position feedback
01:33 AM MarcelineVQ: appearantly the other method to handle this situation in kinematics, but it doesn't look as straightforward
01:34 AM MarcelineVQ: *is kinematics
01:34 AM gloops: yeah seems so, in the sim where X and A are using X step/dir - X jogs but A doesnt respond
01:38 AM MarcelineVQ: try selecting XYZ instead so A's setup step isn't involved. just to check, you are changing pin 8 and pin 9 to also be x step and x dir in the pins page?
01:39 AM MarcelineVQ: 8 / 9 happen to be where A step / A dir is by default, hopefully it's similar for you
01:40 AM gloops: yeah did change the pins to x step
01:40 AM MarcelineVQ: step and dir? :>
01:41 AM gloops: yes both, will double check - will try xyz setup as well
01:41 AM MarcelineVQ: hehe ok
01:42 AM MarcelineVQ: it does seem to be the reccomended option, at least as of 2012 :X https://forum.linuxcnc.org/38-general-linuxcnc-questions/24458-configurate-slave-axis?limit=6&limitstart=0
01:42 AM MarcelineVQ: there's more options later in that thread it looks like
01:43 AM MarcelineVQ: andypugh looks like a good person to ask when he wakes up
01:44 AM gloops: will read that as well thanks, it is no problem at the moment ill just keep having a look and reading a bit here and there, doesnt matter if it takes a couple weeks for me to figure out
01:52 AM gloops: everyone there seems to be saying the xyza way should work, maybe i should just ignore the A altogether once set up
01:52 AM gloops: ill add a motor to the running machine ive got and see if i can get it spinning using that way
01:53 AM MarcelineVQ: you should ignore the A yes, when you set the A's pins to X you're saying these pins are X's now, A won't be able to move because it doesn't have pins anymore
01:54 AM MarcelineVQ: At least, physically it won't be able to move, dunno if that translates to sim
02:01 AM gloops: yes right, the problems arise if ever motor A gets out of step with the original motor X
02:01 AM gloops: loses steps or wracking
02:02 AM MarcelineVQ: yes it could cause a bit of torsion in the gantry
02:03 AM gloops: and out of square
02:03 AM gloops: you can only home X
02:04 AM MarcelineVQ: yeah that's an issue as well, you lose independant motor control for corrections
02:05 AM gloops: kniematics looks like a fair bit of knowledge to take in haha, maybe 2 weeks isnt enough, ive got a month easy anyway
02:08 AM MarcelineVQ: kinematics would let you designate each motor travel as seperate 'joints' and map them to one axis, specifically http://linuxcnc.org/docs/html/man/man9/gantrykins.9.html
02:08 AM MarcelineVQ: that's all I know about it though at this point
02:13 AM gloops: yeah, that is basically what im wanting atm, just a general idea of what im trying to achieve, i need to get the concept of axis and joints as linuxcnc sees them in my head
02:14 AM gloops: that is it - gantrykins
02:15 AM gloops: this wasnt avaialble in older versions i dont think - which makes reading older forum posts a bit confusing - they couldnt do it
02:15 AM gloops: or not without some coding anyway
02:17 AM MarcelineVQ: hmm, there's also http://linuxcnc.org/docs/2.7/html/man/man9/gantry.9.html it seems
02:17 AM MarcelineVQ: either way it looks like we've got to learn all about HAL, which is fine
02:19 AM MarcelineVQ: found that gantry entry by going to http://linuxcnc.org/docs/2.7/html/ and clicking expand man pages at the bottom
02:31 AM gloops: http://linuxcnc.org/docs/2.7/html/motion/kinematics.html
02:31 AM gloops: it is actually well written i can understand this
02:32 AM gloops: one of my earlier complaints about the docs was that they were not easy to understand - i think thats because a certain degree of basic knowledge is required to understand anything about cnc
02:34 AM MarcelineVQ: could be
02:35 AM XXCoder: omg I am alive
02:35 AM MarcelineVQ: omy
02:36 AM XXCoder: internet decided to die
02:37 AM XXCoder: pretty bad storm here heh
02:37 AM MarcelineVQ: ye been pretty stormy this week
02:42 AM Deejay: moin
03:14 AM gloops: axis and joints
03:15 AM gloops: imagine a gantry that ran around a circle, as a radius, sweeping like a clock finger
03:15 AM XXCoder: such machine exists. not quite as you imaged
03:16 AM gloops: there are 2 motors on the gantry, one near the centre and one near the perimeter of the circle or radius
03:17 AM gloops: the motors would need to rotate at different speeds to drive this single axis, this highlights the difference between axis and joints
03:17 AM gloops: does it XXCoder?
03:17 AM XXCoder: not quite as you have discribved
03:18 AM gloops: well i just made that up, i wont be needing help to set one of those up heh
03:18 AM XXCoder: lol
03:20 AM gloops: so, linuxcnc allows to define an axis, and allocate up to 7 joints to each axis
03:21 AM gloops: i just need to know how to script that
03:22 AM XXCoder: ywh mine wasnt that complex so dunno
03:22 AM gloops: you have got simple kinematics - one joint per axis
03:22 AM gloops: trivial kinematics
03:22 AM XXCoder: yep
03:23 AM gloops: 2 joints or more = non trivial kinematics
03:23 AM XXCoder: I know
03:23 AM gloops: which is still fairly trivial once you know how
03:24 AM gloops: its ok ive just read some docs this morning, im just firming up the ideas
03:25 AM XXCoder: LOL
03:25 AM XXCoder: apparently one town was suing cell tower owner for making them ill
03:26 AM XXCoder: then they found out that owner turned it off weeks before
03:26 AM XXCoder: fully 6 weeks before. lol
03:26 AM gloops: could be psychosomatic
03:26 AM XXCoder: no question it is
03:27 AM archivist: you can work outside the kinematics too
03:27 AM gloops: i bet if a local firm put a sign up saying 'this is now a nuclear waste depot' lots of people would start having phantom sicknesses
03:27 AM gloops: archivist in what way?
03:27 AM XXCoder: heh maybe. in any case company wasnt having it so they removed tower and refused to service that town
03:28 AM archivist: Derby had nuclear free zone signs, yet RR had the reactor manufacturing plant !
03:28 AM XXCoder: frankly would you? I wouldn't waste my time trying to make money off town that had sued ,e
03:29 AM archivist: gloops, you can string stuff together in hal see Andy's hobbing setup
03:29 AM gloops: cell phone mast? how are their phones working now then
03:29 AM gloops: archivist will have a look thanks
03:30 AM XXCoder: no idea
03:30 AM XXCoder: probably still using much safer POTS type isp :P
03:31 AM archivist: gloops, this is my version of it http://www.collection.archivist.info/archive/mirror/JS/JShobbingmachine/
03:32 AM archivist: the test setup http://www.collection.archivist.info/archive/mirror/JS/IMG_1731.JPG
03:34 AM archivist: and then later put it on an actual hobbing machine http://www.collection.archivist.info/archive/DJCPD/PD/2014/2014_09_17_Barber_Colman_cnc/IMG_1830.JPG
03:39 AM archivist: next we need to add the differential comp and a cutter rotation to do helicals correctly
03:42 AM gloops: where did you find that machine lol
03:43 AM gloops: looks impressive setup anyway
03:44 AM archivist: it followed me home when I was made redundant
03:45 AM archivist: to see stages of restoration http://www.collection.archivist.info/searchv13.php?searchstr=barber+colman
03:45 AM gloops: ahh, rescued, good work
03:45 AM XXCoder: company went under?
03:46 AM archivist: it was a one man band with one sidekick (me)
03:46 AM MarcelineVQ: XXCoder: made redudant is brit for fired
03:46 AM archivist: he now works from home
03:46 AM XXCoder: MarcelineVQ: I know, can fire lots people before company go under
03:46 AM archivist: I got redundancy moneys and the machines
03:47 AM XXCoder: though clearly not in his case
03:47 AM gloops: at least youre starting with the right lump of metal archivist, if you get that working you should be in business - in business literally
03:48 AM archivist: gloops it has cut gears but there is no work about
03:48 AM gloops: must be surely
03:48 AM archivist: people expect china prices for one offs
03:49 AM XXCoder: lol
03:49 AM MarcelineVQ: china prices can't even pay for material :(
03:49 AM XXCoder: no way is that possible
03:49 AM XXCoder: china do it cheap because they make way more than they need to
03:49 AM gloops: this is only a question of establishing the right product line
03:49 AM gloops: china cannot undercut a machine
03:50 AM gloops: we must identify those products which sell in some volume, which the machine can produce
03:50 AM archivist: try the maths for setting up advertising and feeding oneself
03:52 AM gloops: direct to the consumer - ebay
03:52 AM IchGucksLive: Morning from Germany
03:52 AM XXCoder: hey from stormy tacoma
03:53 AM archivist: gloops, I have actually got to buy a new computer to sell on ebay!
03:53 AM gloops: Ichs, say you had an industrial gear hobbing machine, what would you sell?
03:53 AM XXCoder: arch buy a computer to sell on ebay?
03:53 AM archivist: gloops, mine is 1" max diameter
03:53 AM gloops: archivist £10 on car boot sale
03:54 AM archivist: XXCoder, it fails to upload pics on the browser I have
03:54 AM XXCoder: ahh now that makes sense heh
03:54 AM IchGucksLive: gloops: not norm gears
03:54 AM archivist: now new browser downloads are 64 bit
03:55 AM gloops: im running firefox on 32bit here and now
03:55 AM IchGucksLive: archivist: what is special on your old stepconf from 2013
03:55 AM archivist: odd question
03:55 AM IchGucksLive: archivist: does it fit the new config structre as you linked it
03:56 AM gloops: archivist does it cut rack?
03:56 AM archivist: gloops no
03:56 AM archivist: use a horizontal mill for rack cutting
03:56 AM gloops: you are very limited with 1 inch diameter
03:57 AM archivist: I started modding the 5 axis for larger diameters
03:57 AM gloops: i was think you might be able to combine some of the different abilities and make a whole product
03:57 AM gloops: i dont know, a wine press, theyre popular
03:57 AM gloops: or tools
03:58 AM archivist: tools http://www.collection.archivist.info/archive/DJCPD/PD/2010/2010_07_27_tinware/IMG_0798.JPG
03:58 AM gloops: cnc stuff is selling
03:59 AM archivist: how many need a special tool though http://www.collection.archivist.info/searchv13.php?searchstr=ring+nut+pd
03:59 AM archivist: 3 years ago one off
04:00 AM archivist: I had though of putting that on ebay
04:00 AM gloops: its often how you present it, you might not compete with day to day chinaware, but youre the last of the english craftsman, craftsman made in england = 10x£
04:01 AM gloops: made with english steel
04:02 AM archivist: er steel bought from a uk stockist
04:03 AM IchGucksLive: archivist: what diameter are you talking
04:03 AM gloops: there will be people who are saying - where are we supposed to get a gear cut around here
04:04 AM gloops: just got to make the connections
04:05 AM gloops: who uses gears - card and sample gear delivered in person
04:06 AM IchGucksLive: gloops: we got a GUY here that makes engine fitings he got no teth(almost) and no School finised but he knows what he is doing
04:06 AM IchGucksLive: http://www.motorentechnik-koch.de/bohrenhonen/ LOOK at The viseos
04:07 AM IchGucksLive: it is a garage but all realy big Carmakers are commig even large rase teams
04:07 AM gloops: i had a gearbox go a few years back now, could only find one guy who repaired them in the area (without going to a main dealer for ludicrous money) all he had was a shipping container on a bit of land, he was pulled out with work constantly
04:08 AM archivist: car gears are hardened and ground, different league
04:08 AM IchGucksLive: gloops: as he loks like a Engine maker in his in/area
04:09 AM IchGucksLive: you also can get Car parts from the manufacture with higher precision
04:10 AM IchGucksLive: like Opel in Kaiserslautern 40km away
04:10 AM gloops: doing the old rebore Ichs, thats another service thats getting scarce
04:10 AM archivist: the investment in machines and space
04:10 AM archivist: do the maths
04:11 AM gloops: this happened with welding years ago - when thatcher closed the industry all the welders threw the towel, no work, never thought there would be any more work
04:11 AM IchGucksLive: gloops: most money maker is removing broken sparks
04:11 AM gloops: now today welders are sought after, the work has come back and nobody trained to weld
04:12 AM IchGucksLive: and refitting vent
04:12 AM IchGucksLive: my english is not good enoph to talk on engine parts
04:13 AM IchGucksLive: i got mail from ebay to get PARtner ;-(
04:13 AM IchGucksLive: i recalculated at 100k hits per year and 500 ABO
04:13 AM IchGucksLive: 64Euros
04:14 AM IchGucksLive: SO why shoudt i
04:14 AM IchGucksLive: keep my viewers Advertise Free on that is a better deal
04:14 AM MarcelineVQ: ebay and paypal are pretty scummy companies, its unfortunate they're such a big platform
04:15 AM IchGucksLive: Humens are a good target
04:15 AM IchGucksLive: and best we deport 1984 to 2024
04:15 AM IchGucksLive: as now this boxes are almost everywhere
04:16 AM MarcelineVQ: hopefully, overall the next generation is a bit tired of the bullshit
04:16 AM IchGucksLive: they lison to every word spoken in your house
04:16 AM IchGucksLive: with full conection to DT
04:16 AM XXCoder: MarcelineVQ: honestly each couple generations is very different
04:17 AM XXCoder: yet same
04:17 AM IchGucksLive: Madness has been here since humens take place
04:17 AM IchGucksLive: the Radio as James deen
04:18 AM IchGucksLive: 10 years of smartphone changed the World
04:19 AM XXCoder: someday, brain implants
04:20 AM IchGucksLive: there are already there for invalids
04:21 AM IchGucksLive: hi Ma
04:21 AM IchGucksLive: MaPo:
04:21 AM IchGucksLive: MaPo: wie ist das wetter da unten in bayern
04:22 AM MaPo: Hi die Sonne spitzt leicht durch
04:22 AM IchGucksLive: hier in zweibrücken ist es voll am abregnen
04:23 AM MaPo: hab den Chat gestern erst entdeckt
04:23 AM IchGucksLive: XXCoder: it is like Apple the smartphone has been designed and offerd in 1991 but made the public 2007
04:24 AM IchGucksLive: MaPo: its mainly englich so the world can help
04:24 AM XXCoder: there was tablet in either very late 80s or very early 90s
04:24 AM IchGucksLive: wenn deutsch gewünscht drück zeimal auf meine nick
04:24 AM XXCoder: it could hold 400 charactors. fancy.
04:27 AM gloops: i know what gears do sell on ebay
04:28 AM gloops: changewheels for small lathes, and various gear for the popular small lathes - myford 7 good example
04:28 AM gloops: possibly cast the blanks from scrap aluminium - cost 0
04:28 AM XXCoder: zero cost is impossible
04:29 AM archivist: that first hob setup was for one of the changewheel makers
04:29 AM XXCoder: can be extremely low cost but never zero
04:29 AM gloops: next to nothing, my roofing torch melts ally in seconds
04:29 AM XXCoder: I want to cast pewler evenually
04:29 AM XXCoder: for fun and all
04:29 AM XXCoder: because it can be cast in wood
04:30 AM gloops: they sell plastic ones for the mini lathes, but those are cheaper to inject
04:30 AM gloops: i think the changewheels run about £7 each for specific sizes, there are still plenty of old ones kocking about though
04:31 AM gloops: XXCoder better in casting sand
04:32 AM XXCoder: sure but then im not making precision parts, just making stuff for lols
04:32 AM XXCoder: it may be couple years though, zero space for cnc router, its on shelf in closet now
04:32 AM gloops: good idea though
04:33 AM IchGucksLive: XXCoder: space is always a factor
04:33 AM XXCoder: yep ich
04:33 AM MarcelineVQ: cast it in clay with a wire cutter to shape it
04:34 AM MarcelineVQ: should have less material cost that way compared to wood, if you're doing low temp casts
04:34 AM archivist: when you have to turn upside down, space is a problem http://www.collection.archivist.info/archive/DJCPD/PD/2013/2013_04_15_glass_trolley/IMG_1526.JPG
04:35 AM IchGucksLive: second factor is as always the MONEY
04:35 AM gloops: well actually, making blanks for molds in cnc router is a good idea, as there are no undercuts, you have guaranteed draft built in
04:35 AM gloops: you cut the model you want in wood - not the mold
04:36 AM XXCoder: archivist: lol I can see air in your garage
04:36 AM XXCoder: there is no air in mine now :(
04:36 AM MarcelineVQ: you could do that, but if you have a machine why do the middle step, it can invert the model for you
04:36 AM IchGucksLive: gloops: molds for bakery
04:36 AM gloops: all you have to do is pack that model in sand, turn it over, remove the wood plug - you got a perfect mold
04:36 AM IchGucksLive: gloops: cake makers ...
04:36 AM gloops: fibreglass
04:37 AM gloops: you can melt ally at home, bronze slightly more heat required
04:37 AM XXCoder: I woner how much heat it takes to melt pewler
04:38 AM gloops: you could cast ally gantry plates, only got to surface them
04:38 AM gloops: infact, dont need surfacing
04:38 AM MarcelineVQ: can melt pewter in a house oven if you wanteds to
04:38 AM gloops: not that much
04:38 AM XXCoder: can oven do it? lol
04:38 AM MarcelineVQ: I'd advise against that if you eat with tht oven though
04:39 AM XXCoder: indeed
04:39 AM MarcelineVQ: easier to use a little propane burner
04:39 AM XXCoder: my sis in law would murder me so hard my mom would feel it
04:39 AM gloops: Pewter has a low melting point, around 170–230 °C (338–446 °F), depending on the exact mixture of metals.
04:39 AM XXCoder: plenty high enough to avoid melting in room temperate!
04:40 AM gloops: could do it on cooker ring
04:40 AM MarcelineVQ: I​ imagine we're talking about the same thing when you say cooker ring, little round burner that sits on top of a propane bottle?
04:40 AM gloops: aluminium 630C
04:40 AM gloops: no, the electric or gas ring on the cooker in your kitchen
04:41 AM gloops: cast iron pan
04:41 AM MarcelineVQ: Oh en element
04:41 AM IchGucksLive: im off grandpa needed downstairs
04:41 AM gloops: bronze = 950C
04:42 AM archivist: I use a cooker element for my bluing kiln
04:42 AM gloops: ive melted lead on cooker for fishing weights, was ushered outside though
04:44 AM XXCoder: yeah lead vapor is super fun
04:44 AM gloops: never bothered me im as sane as the next man...
04:45 AM MarcelineVQ: I'm as sane as the next voice
04:46 AM gloops: someone with a real mill could make a steel mold
04:47 AM archivist: I used plaster to cast lead in a few times
04:47 AM gloops: doesnt take heat so well
04:48 AM MarcelineVQ: learned about babbit recently, very interesting stuff
04:48 AM gloops: well, i didnt not get to the end of the 10th reading about joints so thats something for later
04:50 AM XXCoder: gloops: even my machine could mill steel, given enough time lol
04:50 AM XXCoder: I dont plan to mill steel at all
04:50 AM archivist: I got 7 weights out of one mould
04:50 AM MarcelineVQ: I do, muahahaha, some way down the road
04:59 AM jthornton-: morning
04:59 AM XXCoder: hey jtminus
05:00 AM jthornton-: it's 70f right now and the high for today is 69f
05:02 AM jthornton- is now known as jthornton
05:06 AM XXCoder: somewhat cooler here
05:06 AM XXCoder: my room humidity is at 75%
05:07 AM XXCoder: should be lower now with warmer temperate but I'm waiting for dehumidifer to arrive
05:10 AM phipli: morning
05:11 AM jthornton: morning
05:11 AM jthornton: light came on, door went up, chickens went out
05:11 AM phipli: it is 51*F here
05:11 AM phipli: excellent
05:11 AM phipli: could I see your latest code?
05:11 AM XXCoder: I think its around 60f here. 1000% humidity outside lol
05:11 AM XXCoder: raining very hard
05:12 AM XXCoder: washington state is in its "welcome, fall!" mode.
05:12 AM phipli: just a bit windy today
05:12 AM XXCoder: evenually we will finally see sun and get reminded what clear sky looks like.
05:13 AM phipli: whats left of an atlantic storm arrived last night
05:13 AM jthornton: the arduino code?
05:13 AM phipli: not as bad as predicted
05:13 AM phipli: are you using an arduino on the door atm, or that python code?
05:14 AM jthornton: nano is still opening the door, going to hook up some relays to the pi this morning and start experimenting with it
05:15 AM jthornton: wow I have an extra 3.5 GB of data usage at this point
05:16 AM phipli: to use, or that you've used?
05:16 AM jthornton: to use
05:16 AM jthornton: I wrote a python program to show me where I should be at the time of month lol
05:17 AM XXCoder: lol nice
05:17 AM XXCoder: got unlimited here
05:17 AM phipli: I still think you should compress the data going through your connection JT :p
05:18 AM jthornton: http://paste.ubuntu.com/25792436/
05:18 AM jthornton: compress the incoming data?
05:18 AM phipli: XXCoder, they finally rolled out fttc on this street so we're back on fibre after having had to drop back down to DSL when we moved house
05:18 AM phipli: jthornton, both directions
05:19 AM XXCoder: fancy. cable here. comcast/xfinity
05:19 AM XXCoder: sucks but well
05:19 AM phipli: XXCoder, the main / only cable supplier here is...
05:19 AM phipli: unhelpful
05:19 AM phipli: best headline speeds, but shape like they're at a 1980s rave
05:20 AM phipli: last time I used them, their 70mb connection used to drop under 1mb at peak times
05:20 AM phipli: and their customer support doesn't exist
05:21 AM archivist: main adsl supplier is a royal pain also
05:21 AM phipli: BT?
05:21 AM phipli: yeah
05:21 AM phipli: fine as long as you don't have an issue
05:21 AM phipli: then... good luck
05:21 AM archivist: bunch of bar stewards
05:22 AM phipli: it has been a race to the bottom
05:22 AM phipli: everyone bought the cheapest internet they could...
05:22 AM phipli: and so the ones that provided a decent service went under
05:22 AM phipli: and we're left with the ones that cut corners
05:23 AM archivist: and screw the customer
05:27 AM archivist: any merican used one of these? http://www.ebay.co.uk/itm/4-3-Screen-Wolverine-Titan-8-in-1-High-Resolution-Film-to-Digital-Converter-New-/282681481512
05:27 AM XXCoder: thats pretty cool
05:28 AM XXCoder: but nope for me
05:29 AM archivist: currently going through and sorting my old film stuff
05:30 AM phipli: my dad's scanner has a light in the lid for scanning slides / film
05:31 AM phipli: new it was a fancy machine
05:31 AM archivist: I have one of those but resolution not good enough really
05:31 AM phipli: even second hand that thing is probably cheaper
05:31 AM phipli: heh
05:31 AM phipli: you could see the blobs in the film on my dads
05:32 AM phipli: he got it for work and it needed to be high res
05:32 AM jthornton: I wonder if I still have the negatives from years ago
05:32 AM archivist: epson Vsomething?
05:32 AM phipli: no...
05:32 AM phipli: I can't remember though
05:32 AM phipli: it wasn't a common consumer brand
05:33 AM archivist: http://www.ebay.co.uk/itm/Open-Box-Grade-OpenBox-Epson-Perfection-V800-Film-and-Photo-Scanner-/292289872520
05:33 AM archivist: not consumer priced :)
05:33 AM phipli: does 48 bit colour though
05:33 AM phipli: good for fixing faded photos
05:35 AM phipli: if you just have a batch to do, sometimes it can be worth buying second hand, then selling when you're done
05:35 AM phipli: might even make a profit
05:35 AM phipli: (might)
05:36 AM phipli: Lol - not to be mean...
05:37 AM phipli: but just heard the kid next door stomping around giggling, followed by a "tump" of it running into something
05:37 AM phipli: -> tears
05:37 AM phipli: poor kid is very clumsy
05:37 AM phipli: it is tragically comical how well you can hear it happen
05:37 AM archivist: this is slide quality I get http://www.collection.archivist.info/archive/Lucas/PS/PA11/ps1636.jpg
05:37 AM jthornton: that's too close for me
05:38 AM phipli: jthornton, adjoining walls?
05:38 AM phipli: me too
05:38 AM phipli: I'm a country boy, but... money / work / life
05:39 AM phipli: one day I'll have enough room to play music loudly and not hear other people's arguments
05:39 AM phipli: archivist, at work we still have microfiche - they're amazing
05:39 AM archivist: I cannot scan fiche yet but have about 5k to scan!
05:40 AM phipli: archivist, the resolution isn't /bad/ it is almost like it is slightly out of focus?
05:40 AM phipli: the jpg compression is quite high on that image - can see it in the highlights
05:40 AM archivist: my image was done on this epson 3200
05:40 AM phipli: (but obviously - internet)
05:41 AM XXCoder: phipli: some of more... shady isps compress images
05:41 AM phipli: heh
05:41 AM phipli: XXCoder, our mobile providers do
05:41 AM XXCoder: definitely
05:41 AM phipli: was reading that some of yours block ports!
05:42 AM XXCoder: bloc ports?
05:42 AM phipli: "for your safety there can be no incoming traffic on port 80"
05:42 AM XXCoder: ahh yeah
05:42 AM phipli: aka "we want to force you to buy our pro package"
05:42 AM phipli: I don't think I've ever heard anything like that over here
05:43 AM XXCoder: "uniquely american"
05:44 AM phipli: you also have expensive internet I hear
05:44 AM phipli: due to effective monopoly etc.
05:44 AM phipli: our main issue is quality of service
05:45 AM phipli: speeds plummet at certain times of the day
05:45 AM XXCoder: comcast sucks
05:45 AM phipli: I think you spelt USA wrong that last time - there isn't a G in it :)
05:46 AM XXCoder: lol
05:46 AM phipli: we're allowed guns too...
05:46 AM phipli: we just... don't
05:46 AM phipli: for the most part
05:46 AM XXCoder: usa is great in some ways and "great" in others
05:47 AM phipli: you're small scale industry is impressive
05:47 AM XXCoder: show me country with no cons and I'll show you a country with no people in it ;)
05:47 AM phipli: high technology seems to make it into back street workshops
05:47 AM phipli: here....
05:47 AM phipli: high tech often means big companies
05:47 AM phipli: *you're = your
05:48 AM phipli: this place is tearing itself to pieces
05:48 AM phipli: in certain ways
05:49 AM phipli: seems to be an international thing though - vote populist - vote to end days
05:49 AM XXCoder: there might be signs that usa is turning corner in some ways
05:49 AM XXCoder: utter impotent people is beng booted out
05:50 AM XXCoder: issues at top though
05:51 AM phipli: we have a lot of professional MPs that are all from the same background
05:51 AM phipli: with more personal interests than anything else
05:51 AM phipli: (MP = member of parliament - the people that make the decisions and vote on things)
05:52 AM phipli: But on the plus side, it is quite a nice place to live
05:52 AM phipli: on the macro scale
05:53 AM XXCoder: 73 ADA requirements was cut out of school rules :(
05:53 AM phipli: as long as you're not one of the various groups of people that the government is paying too much attention to
05:53 AM XXCoder: too bad for disabled people eh
05:53 AM phipli: 73 ADA?
05:54 AM XXCoder: americans with disabilities act
05:54 AM XXCoder: 73 rules was removed, all related to schooling kids
05:54 AM phipli: we've (if I have this right) just consolidated lots of our benefits into a single system, where if you have any issues there is a six week waiting time...
05:54 AM phipli: effectively meaning that some people, who specifically by definition are short of cash, are having to do without for a long time
05:55 AM XXCoder: its not benefits related, rules ensuring disabled kids have equal oppunity to learn
05:55 AM phipli: they even (initially) made the helpline cost 55p (73c) per minute
05:55 AM jthornton: damn
05:56 AM phipli: XXCoder, guessing the effect is that they end up going to dedicated schools that cost money...
05:56 AM phipli: so if you can't they don't?
05:56 AM XXCoder: or just ignored
05:56 AM phipli: sigh
05:56 AM phipli: I'd like to think our government would be lynched if they tried that
05:56 AM phipli: but lately I've been surprised
05:57 AM XXCoder: inhuman goverments popping up all over nowdays
05:57 AM phipli: It seems more difficult to do something about these days (not that I remember anything different)
05:57 AM phipli: my parents talk about doing things back in the day to get things changed...
05:58 AM phipli: now you seem to just get fired / arrested / etc.
05:58 AM XXCoder: did you know deaf unemployement was orginially 90%?
05:58 AM phipli: blimey
05:58 AM phipli: I'll see if I can find what it is here
05:58 AM XXCoder: its 75% or so thanks to changes
05:58 AM XXCoder: I predict it will be back to 90% or worse
05:58 AM XXCoder: old days new management usually means "that deaf guy gets fired to show im tough manager"
06:01 AM phipli: we have stronger employment law here
06:01 AM phipli: the company could be taken to court for that
06:01 AM phipli: although interestingly, when such things actually happen, many people don't have the financial security or confidence to do wo
06:01 AM XXCoder: indeed. though I have heard 2 stories where apparently deaf guy was vital employee ion company
06:01 AM phipli: *so
06:02 AM phipli: XXCoder, great story I heard once (be it true or not)
06:02 AM XXCoder: in both cases they was fired without reviewing what they do, and other employees complained
06:02 AM phipli: someone on a car production line went on holiday and the line stopped because nobody could fit a certain bolt
06:02 AM phipli: turns out the guy on holiday had missing fingers and could get his hand to the location
06:03 AM XXCoder: in one case, company suffered a lot and nearly went under. in other, that deaf guy sued. with very strong case and witnesses of other employees guy won
06:03 AM phipli: the issue of access hadn't been flagged because he'd just done them all
06:03 AM XXCoder: second one he got back to working with same pay and senority
06:03 AM XXCoder: that is .. nuts heh
06:04 AM phipli: XXCoder, are things better generally?
06:04 AM phipli: things have improved a lot over the years here
06:04 AM XXCoder: it is, well it was. not too sure now
06:05 AM XXCoder: usa just let program to aid kids healthcare expire
06:05 AM XXCoder: and they refused to vote on it so it seems to be dead now
06:05 AM XXCoder: from wat I see, you swim on your own or you sink
06:06 AM phipli: are states any better than central government?
06:06 AM phipli: guess it depends
06:06 AM XXCoder: depends on state
06:06 AM phipli: private organisations?
06:07 AM phipli: In our history, before the government started caring about the population at all here, a number of companies provided a lot of support to their staff
06:07 AM phipli: built villages for workers, provided at cost food etc.
06:07 AM phipli: some on the other hand used it to do their staff over... but that is another story
06:08 AM phipli: (paid in vouchers that could only be used at company shops)
06:08 AM XXCoder: heh yeah company scrip
06:09 AM XXCoder: its really mean way to pay employees
06:10 AM phipli: Can't wait to be self employed
06:10 AM phipli: on the assumption I can make it work
06:11 AM phipli: the missus has gone into IT / Database management where it seems to be the norm
06:11 AM phipli: (the logical progression from her German degree)
06:11 AM XXCoder: I'd be awful boss for myself
06:11 AM phipli: heh
06:12 AM phipli: yeah - spoke to my brother a while back after he'd done 4 days without going to bed
06:12 AM phipli: his boss is a right evil sod
06:12 AM phipli: (self employed)
06:13 AM jthornton: well crumb I copied the wrong program to the nas ... back out to the shop I go
06:13 AM phipli: :)
06:13 AM XXCoder: aw
06:13 AM phipli: send a chicken to do it
06:14 AM XXCoder: phipli: 96 hours of work without sleep? insane
06:14 AM phipli: "well, the correct file hasn't been uploaded and I seem to have ordered loads of chicken treats on amazon"
06:15 AM phipli: XXCoder, I don't know how he does it - he worked 2 jobs where there was only 3 hours in the day that he wasn't "at work" for a month a few years back
06:15 AM phipli: slept in his lunch break
06:15 AM phipli: and the 3 hours not working included travel home
06:15 AM phipli: crazy guy
06:15 AM XXCoder: crazy
06:18 AM JT-Shopp is now known as JT-Shop
06:43 AM phipli: so... has anyone ever CNC carved a pumpkin?
06:44 AM jthornton: https://www.youtube.com/watch?v=jX4CnEJoYA8
06:45 AM jthornton: https://www.youtube.com/watch?v=IqxrNhSvOWM
06:46 AM jthornton: http://paste.ubuntu.com/25792846/
06:46 AM jthornton: got more code worked out for the door
06:48 AM XXCoder: jthornton: with probing that would be even more awesome.
06:49 AM XXCoder: night
06:49 AM jthornton: goodnight
06:52 AM gloopskins: no phipli i dont believe they have
06:53 AM gloopskins: ahh just clicked those links lol
07:15 AM phipli: jthornton, https://www.raspberrypi.org/documentation/usage/gpio-plus-and-raspi2/README.md
07:15 AM phipli: for when you need it
07:16 AM jthornton: yes I have that link and this one as well https://pinout.xyz/pinout/i2c#
07:17 AM jthornton: the latter one shows you what pins will be used by modules like i2c which is cool
07:17 AM * jthornton just connected to the Rpi with Filezilla :)
07:18 AM phipli: https://gpiozero.readthedocs.io/en/stable/
07:19 AM jthornton: is gpiozero better than GPIO?
07:20 AM phipli: I don't know sorry
07:20 AM phipli: it is years since I've done a raspberry pi python gpio project
07:20 AM phipli: you might be interested in this : https://learn.adafruit.com/webide/overview
07:20 AM phipli: a browser based ide that you host on the raspberry pi
07:21 AM phipli: lets you edit programs and deploy them etc. from the comfort of your main computer
07:21 AM phipli: https://learn.adafruit.com/webide/overview
07:21 AM phipli: heh whoops, sorry, double post
07:27 AM jthornton: lol forgot to set the timezone on the Rpi so it thought it was at your house
07:27 AM phipli: :)
07:28 AM phipli: makes a change - it is usually the other way around :P
07:28 AM archivist: but our timezone it the right one!
07:28 AM archivist: is/is
07:28 AM phipli: :)
07:30 AM phipli: archivist, the chickens probably wouldn't appreciate their door opening based on our sunrise and sunset...
07:30 AM archivist: pfft
07:39 AM Jymmm: phipli: The chickens wouldn't mind, but the predators would enjoy it ;)
07:40 AM phipli: :)
07:40 AM phipli: jthornton, http://elephantandchicken.co.uk/misc/20171022/index.html
07:42 AM Tom_L: 44F
07:42 AM Jymmm: 43F
07:43 AM jthornton: 70F
07:43 AM jthornton: phipli: how old are the new ones now?
07:44 AM * Jymmm sets jthornton chicken pi to randomly change the TZ daily.
07:45 AM archivist: is that a chicken pie
07:46 AM Jymmm: <rim shot>
07:50 AM phipli: jthornton, if the breeder had told the truth, they'd be 6 months old
07:50 AM phipli: but there is no way they were 12 weeks when we got them
07:50 AM phipli: they're developing a lot slower than our hybrids did
07:50 AM phipli: regardless
07:53 AM jthornton: I noticed that all of my chickens seem to develop at different rates and they were all born on the same day for sure
07:59 AM phipli: I like your picture with Henry looking up your leg past the other chickens
07:59 AM phipli: the expression he's pulling
07:59 AM jthornton: yea he is a character for sure
08:00 AM jthornton: doesn't like to be picked up or petted, the hens don't seem to mind
08:00 AM jthornton: phipli: latest code http://paste.ubuntu.com/25793293/
08:01 AM jthornton: I think I just need to add the inputs and I'm ready to test it
08:04 AM phipli: make sure they're 3.3v
08:05 AM jthornton: my relays?
08:05 AM phipli: whatever inputs go into the raspberry pi
08:06 AM jthornton: ah ok, just reading the sparkfun tutorial for gpio
08:24 AM jthornton: using FileZilla to transfer the python program to the Rpi makes it too easy lol
08:36 AM jthornton: phipli: getting close to finished code, just need to make the motor shut off as soon as the switch closes
08:36 AM malcom2073: jthornton: Coop door?
08:37 AM Jymmm: malcom2073: jthornton has an automated door for his chicken coop
08:37 AM malcom2073: Nice
08:37 AM jthornton: malcom2073: yep
08:38 AM jthornton: so much easier to do in python and the Rpi it ain't funny
08:38 AM malcom2073: Yeah, I've been playing with python lately, the rpi is a really nice package
08:47 AM jthornton: I really like that I can use FileZilla to transfer files back and forth from the Rpi and my linux pc
08:47 AM malcom2073: Do you use the command line much?
08:47 AM jthornton: some but writing programs in nano sucks
08:48 AM malcom2073: You can use scp to transfer a single file to a specific location, much like filezilla does (such as when you update your code file), I have my editor automatically scp my file over when I save it
08:48 AM jthornton: which editor?
08:49 AM malcom2073: I use notepad++, but it's windows only
08:49 AM jthornton: I use that as well on my windoze pcs
08:50 AM malcom2073: NppFTP is the plugin that allows it
08:50 AM malcom2073: you can open "remote" files, and every time you save them, it transfers them over
08:51 AM jthornton: I do all my programming on my linux pc's
08:51 AM malcom2073: If linux would run on my laptop I would, I miss it heh
08:51 AM malcom2073: for now, I mainly run it in VMs
08:53 AM Jymmm: malcom2073: Huh? If your laptop can run VM's, it can run linux.
08:54 AM jthornton: my laptop is setup for dual boot
08:54 AM malcom2073: Jymmm: I have a laptop with a discrete nvidia card, linux support for that isn't stable yet it seems, and my laptop is one of those on which it doesn't work
08:55 AM jthornton: breakfast time here
08:55 AM Jymmm: malcom2073: Oh, video bs, yeah I get it. I haven't had to deal with that for years (running Mac's)
08:56 AM malcom2073: Yeah, I try every few months, but as of yet I've not found a distro that works out of the box, or even one that I can get working within a couple hours of attempts
08:56 AM Jymmm: malcom2073: virtualbox?
08:56 AM malcom2073: Jymmm: Yeah, virtualbox runs great, when I full screen it, it feels almost as fast as native heh
08:56 AM malcom2073: (ignoring any 3d stuff)
08:57 AM Jymmm: malcom2073: Try knoppix (it's a live cd/DVD), I've been very impressed over the years at how well it detects hardware without configuration.
08:58 AM malcom2073: Jymmm: booting isn't an issue, getting video working is. knoppix boots sure, but if I want to run without graphics acceleration, a VM is just as good
08:59 AM malcom2073: ubuntu won't even boot, debian and arch both boot, but both bomb out once I do anything to try to get the nvidia card up
08:59 AM Jymmm: malcom2073: fair enough =)
08:59 AM malcom2073: It's damn fast though, even using onboard video heh
10:36 AM gloops: i donthave a [KINS} section in ini file
10:41 AM gloops: is this only v2.8?
11:00 AM MarcelineVQ: gloops: looks like it. in 2.7 you'll find JOINTS in [TRAJ] the actual kinematics in use is going to be set by your hal files, I'm expecting
11:00 AM gloops: version 8 = master-rt?
11:01 AM gloops: ah thanks Marcel
11:02 AM MarcelineVQ: where are you seeing master-rt btw
11:04 AM gloops: in repositories synaptic
11:04 AM MarcelineVQ: Oh okay
11:05 AM gloops: http://buildbot.linuxcnc.org/wheezy master-rt
11:06 AM gloops: the tutorial ive been reading is using 2.8 - only just realised, im on 2.11
11:06 AM MarcelineVQ: that's a handy link
11:07 AM gloops: link doesnt work for me heh, was just showing where i saw it, is that version 2.8?
11:07 AM MarcelineVQ: link I ​mean is http://buildbot.linuxcnc.org/
11:07 AM hazzy: gloops: I think you meant 2.7.11, or are you in the future? ;)
11:07 AM gloops: im on 2.7.11
11:08 AM gloops: hazzy right, so how do i get on to 2.8?
11:08 AM hazzy: You can get 2.8 from the build bot
11:09 AM hazzy: you can do it in synaptics
11:11 AM gloops: trying..i am not very good with linux
11:12 AM hazzy: It has been a long time since I installed from the bot since I build from source, so I I don't know how off the top of my head
11:12 AM hazzy: sek, let me try to remember :)
11:12 AM gloops: its upgradinf linuxcnc anyway this might be it
11:12 AM MarcelineVQ: just for clarification is master 2.8, I assume so since there isn't a 2.8 branch on git
11:13 AM hazzy: yes, master is 2.8 pre
11:13 AM gloops: yes i think it is Marcel
11:13 AM MarcelineVQ: thank you
11:15 AM gloops: yes that was painless..so far, on version .8
11:16 AM hazzy: great!
11:18 AM gloops: yes ive [KINS] im happy again now haha
11:19 AM gloops: slightly improved stepconfig appearance
11:19 AM MarcelineVQ: are you following a tut?
11:20 AM gloops: ive read one a few times and kinda understand it, was a bit confused by me using the older ini file
11:20 AM gloops: this is a much better way to look at it - in the 2.8 ini i think, just at a glance
11:20 AM gloops: clear distinction between axis and joints
11:21 AM gloops: just working with this - or going to try it anyway - file:///home/gloops/Desktop/How%20to.%202%20or%20more%20motors%20on%20one%20axis.%20Gantry%20LinuxCNC%202.8%20Master%20-%20LinuxCNC.html
11:22 AM gloops: no not that lol
11:22 AM MarcelineVQ: https://forum.linuxcnc.org/49-basic-configuration/33079-how-to-2-or-more-motors-on-one-axis-gantry-linuxcnc-2-8-master
11:22 AM MarcelineVQ: thank you
11:22 AM gloops: yes that one thanks
12:01 PM IchGucksLive: hi all ;-)
12:03 PM hazzy: hello Ichs :)
12:05 PM IchGucksLive: as night falls wetter vlears up
12:44 PM phipli: did you have a storm?
12:44 PM phipli: it wasn't too bad here - less than we were expecting
12:45 PM jthornton: we just got a sprinkle here
12:46 PM jthornton: phipli: http://paste.ubuntu.com/25795453/
12:47 PM phipli: just got some RGB leds working properly on an Orange Pi...
12:47 PM phipli: really wasn't worth it
12:47 PM jthornton: the orange or the leds
12:47 PM phipli: worked on the third library
12:47 PM phipli: and I had to modify the library to make it work perfectly
12:47 PM jthornton: I just added a timeout for the motors
12:48 PM jthornton: yuck
12:48 PM phipli: the libraries are half ports of raspberry pi libraries
12:48 PM phipli: that don't quite work
12:48 PM * jthornton is liking his Rpi more and more :)
12:48 PM phipli: :p
12:48 PM phipli: so many people use the raspberry pi that the software is so much more mature
12:48 PM IchGucksLive: phipli: use dmx512
12:49 PM phipli: I'm using SPI to drive ws2812 leds
12:49 PM phipli: dmx would be... overkill
12:49 PM IchGucksLive: get your own disco
12:50 PM phipli: I used to do light and sound things when I was a teenager
12:51 PM phipli: leaving home broke the connections
12:51 PM phipli: besides, other things to do these days :)
12:52 PM jthornton: hmm just need to add my manual override inputs and I think I'm done
12:53 PM IchGucksLive: phipli: exactly like here no more music since 1988
12:53 PM IchGucksLive: bevor every weekend on tour
12:55 PM phipli: the guy I did it with also moved away - joined his uncles company doing sound for big shows and things
12:55 PM phipli: does it full time
12:55 PM phipli: I went and did engineering instead :)
12:56 PM IchGucksLive: as here
12:56 PM IchGucksLive: i made my master and went off nightshifts
12:56 PM IchGucksLive: remains still here in this room a 40k laserbank
12:57 PM phipli: dinner time :)
12:58 PM Tom_L: IchGucksLive, those rail kits you use.. are the ballscrews decent quality?
12:58 PM jthornton: enjoy
12:59 PM Tom_L: IchGucksLive, such as these: https://www.ebay.com/itm/US-Stock-3Set-Ballscrew-1605-400-700-1000-Square-Linear-guide-rail-BKBF-Nut-CNC/112600628788?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649
01:00 PM Tom_L: cold rolled C7
01:02 PM IchGucksLive: my supplyer claims C5
01:03 PM IchGucksLive: i got no backlash
01:03 PM Tom_L: is C5 better?
01:03 PM IchGucksLive: but i dident messure the length flow
01:03 PM IchGucksLive: yes
01:03 PM Tom_L: those look like the same ones you had only uk supplier
01:03 PM Roguish: hey all. anyone using 'Probe_screen' ??
01:03 PM IchGucksLive: Tom_L: ratmmotors also sells in usa
01:04 PM Roguish: in Master?
01:04 PM archivist: c7 is rattling fit :)
01:05 PM Tom_L: can't be worse than my sherline
01:05 PM IchGucksLive: Tom_L: you are in USA
01:05 PM Tom_L: yup
01:05 PM archivist: see table at bottom http://www.designworldonline.com/what-to-look-for-when-choosing-a-precision-ball-screw/
01:06 PM * Tom_L waits for all the ads to load
01:07 PM IchGucksLive: Tom_L: http://stores.ebay.com/Rattmmotor?_trksid=p2047675.l2563
01:07 PM IchGucksLive: USA Stock http://stores.ebay.com/Rattmmotor/USA-delivery-no-taxes-/_i.html?_fsub=8325379011
01:08 PM IchGucksLive: BEST price USA https://www.ebay.com/itm/US-20mm-Square-Block-Linear-guide-rail-3-Ballscrew-1605-400-700-1000-BK-BF-HGH20-/263268341882
01:09 PM Tom_L: they're all about the same
01:09 PM Tom_L: alot advertise 361 and 70 shipping
01:10 PM IchGucksLive: 420 USD is quide a good price for the items you get
01:10 PM Roguish: general rule of thumb on rails and ball screws is quality = cost.
01:11 PM Roguish: more important though is to consider the complete system, and try not to overpay or underpay.
01:11 PM IchGucksLive: Rug but for a c2 1m you pay 500USD
01:11 PM IchGucksLive: and noone of us needs this
01:12 PM IchGucksLive: if you retrofit a Hermle or Haas 25k mashine with full servo low
01:12 PM IchGucksLive: but not on woodcarving
01:13 PM IchGucksLive: the simple TR20x4 will do the job as good on 8Nm steppers
01:13 PM IchGucksLive: at !73 the cost
01:13 PM IchGucksLive: 1/3
01:13 PM Roguish: that's what I mean by try not to overpay or underpay. always consider the actual usage. wants are not always needs.
01:15 PM IchGucksLive: next china step will be the change from 1605 to 2005
01:15 PM IchGucksLive: as then 1500mm is a real playground
01:17 PM IchGucksLive: i think all the spindles coming from mainly one Producer AS it chainches Rolltool it comes c4 to mashine makers
01:17 PM IchGucksLive: then about 100m of c5
01:17 PM IchGucksLive: then go for as many c7 it takes
01:18 PM IchGucksLive: as ive seen images of a precision dial to mesure the outcome
01:19 PM IchGucksLive: its simply sorted out
01:19 PM IchGucksLive: hi to florida
01:19 PM IchGucksLive: BeachBumPete: how is your weather
01:19 PM IchGucksLive: winter knocking on the door
01:22 PM Tom_L: IchGucksLive, what size bolts hold the rails? 6mm?
01:22 PM Tom_L: hex cap screws
01:23 PM BeachBumPete: hello ich
01:23 PM BeachBumPete: weather is BEAutiul
01:23 PM Tom_L: same here
01:23 PM BeachBumPete: ful
01:23 PM Tom_L: calm sunny day
01:23 PM BeachBumPete: workin on the CNC while Dacia makes some halloween stuff with the kids
01:23 PM Tom_L: nice, get the carousel goin...
01:24 PM Tom_L: :)
01:24 PM BeachBumPete: yeah I wish LOL
01:24 PM IchGucksLive: Tom_L: the hole is 6,2mm
01:24 PM Tom_L: thanks
01:24 PM Tom_L: IchGucksLive, do you shim under the rails at all to ensure flatness?
01:25 PM IchGucksLive: as i use AL profile i got 10mm al beneeth
01:25 PM Tom_L: if i do this, i'm planning a steel frame
01:25 PM Tom_L: box tube
01:26 PM Tom_L: or such
01:26 PM Tom_L: i'm not wanting a gantry style though
01:26 PM IchGucksLive: up to you
01:26 PM Tom_L: wonder which is more practical to build
01:27 PM IchGucksLive: 5axis
01:27 PM Tom_L: no, style
01:27 PM Tom_L: gantry or like a bridgeport knee mill
01:28 PM Tom_L: found cad models for the rails
01:28 PM IchGucksLive: there are so many old bridgeport knee mills out why not retrofit one
01:28 PM Tom_L: no room
01:28 PM Tom_L: i need something smaller
01:28 PM Tom_L: but want something more rigid than a sherline
01:28 PM phipli: *a bigger building
01:29 PM Tom_L: if i were planning to go into production i would
01:29 PM Tom_L: but this is a toy
01:29 PM Roguish: Tom_L: that's what I'm contemplating also
01:29 PM Tom_L: my bud had a 60k sq ft shop
01:29 PM archivist: plan ahead for more toys
01:29 PM IchGucksLive: Tom_L: depends on workarea
01:29 PM jdh: that's a closet, not a shop
01:29 PM Tom_L: started out in a 2 car garage
01:29 PM Tom_L: moved twice
01:29 PM jdh: oh, 60k, not 60ft
01:30 PM Tom_L: final building was ~60k sq ft
01:30 PM Tom_L: probably 10-15 cnc of various types
01:30 PM Tom_L: mostly tree and okuma
01:30 PM Tom_L: but he retired and sold it all
01:30 PM jdh: I get the edges of a 3 car garage that aren't full of dive gear or bikes
01:31 PM Tom_L: he had a fadal in his first garage shop
01:31 PM IchGucksLive: https://www.youtube.com/watch?v=ACPFDnKS_0M
01:31 PM Tom_L: along with a bridgeport tracer, boss 5 and a few other things
01:32 PM jdh: anyone want to buy a converted g0704 or a 90% converted jet 9x20?
01:32 PM Tom_L: those rails are kinda long for a desktop machine
01:32 PM Tom_L: 1k mm on x
01:33 PM IchGucksLive: Tom_L: there are a single set 500mm
01:33 PM IchGucksLive: and the bascrew set for it
01:33 PM Tom_L: is it practical to cut em?
01:33 PM IchGucksLive: yes
01:34 PM Tom_L: how much cheaper are the 500mm ones?
01:34 PM IchGucksLive: you can also drill holes wher you need them
01:34 PM Tom_L: haven't found a 'kit' per se for those
01:34 PM Tom_L: yeah
01:37 PM IchGucksLive: Tom_L: item number 272864129945
01:37 PM gregcnc: is shill bidding allowed on ebay.de?
01:38 PM IchGucksLive: gregcnc: sorry i do not know what that is
01:38 PM IchGucksLive: Tom_L: there are also 1605
01:38 PM gregcnc: when you bid on your own auction to raise the price
01:39 PM IchGucksLive: no
01:39 PM Tom_L: so get a friend to bid
01:39 PM gregcnc: this item I want has been won by the same zero feedback user twice now
01:40 PM Tom_L: IchGucksLive what's the pitch on the ballscrews in the kit you use?
01:40 PM Tom_L: 16mm screw
01:40 PM IchGucksLive: the number says it 16diameter 5mm pitch
01:41 PM IchGucksLive: 1605
01:41 PM IchGucksLive: 2005 is 20mm diameter
01:41 PM BeachBumPete: I need to plumb my AC into the shop here man LOL
01:41 PM Tom_L: ahh ok
01:41 PM Tom_L: thanks
01:41 PM archivist: gregcnc, that happened to me, then got an offer from the seller, I ignored him :)
01:41 PM Tom_L: so one round moves 5mm linear
01:41 PM Tom_L: ... just checking..
01:42 PM IchGucksLive: yes
01:42 PM IchGucksLive: go for timingbelt 20/25 to fit stepepr
01:42 PM Tom_L: nema23 ok?
01:42 PM IchGucksLive: or a HSS86 1000steps
01:42 PM IchGucksLive: yes
01:42 PM IchGucksLive: 3Nm
01:42 PM Tom_L: i've already got gecko stuff and nema 23 steppers
01:43 PM Tom_L: these are either double or triple stack

01:44 PM IchGucksLive: the prices has droped almost 25% since last order
01:44 PM Tom_L: i'd have to look
01:45 PM Tom_L: you belt drive all yours?
01:45 PM Tom_L: no direct drive
01:46 PM IchGucksLive: Tom_L: can you tell me the USA price https://www.ebay.com/itm/US-Ship-4pcs-High-Torque-Nema23-Stepper-Motor-425oz-in-2-8N-m-4-Lead-DIY-CNC-Kit-/263268354293
01:46 PM Tom_L: $98 us
01:46 PM IchGucksLive: Tom_L: yes i did not make any mashine on direkt
01:47 PM gloops: really cheap
01:47 PM IchGucksLive: keep serching the US item
01:47 PM gloops: theyre about £25-30 each here
01:47 PM IchGucksLive: it my be shiped on high cost
01:47 PM Tom_L: 40 shipping
01:47 PM IchGucksLive: gloops: price has dropped
01:48 PM Tom_L: so ~$35 us shipped ea
01:48 PM IchGucksLive: AS i Said so offen ebay wont let me search for US items
01:48 PM IchGucksLive: search 425oz steppers
01:48 PM Tom_L: i'm lookin for the specs on mine
01:48 PM IchGucksLive: klick ship free on side
01:48 PM gloops: Ichs im keeping my eye on the 1200oz closed loop, think ill invest in some of those at some point, ive already got motors for what i need
01:49 PM IchGucksLive: WHY that hard
01:49 PM gloops: if china economy swings back the prices will be up again
01:49 PM IchGucksLive: gloops: it needs alot of power
01:49 PM IchGucksLive: go for the (Nm that will fit your need
01:49 PM IchGucksLive: 8Nm
01:49 PM gloops: they would be good for large router table
01:49 PM gloops: 8x4
01:49 PM IchGucksLive: im off bye F1 Austin texas
01:49 PM gloops: goodnight
01:50 PM Tom_L: yeah mine are 282 in oz
01:50 PM Tom_L: on the sherline
01:52 PM gloops: do they give enough power for milling steel Tom?
01:52 PM Tom_L: with small bits but the sherline isn't really rigid enough for steel
01:52 PM gloops: ahh right
01:52 PM Tom_L: i've cut some with it slowly
01:53 PM Tom_L: i'd be better off getting some 400ish oz in steppers for a larger build
01:53 PM gloops: i keep looking at small mills, maybe get one next year, old one probably
01:53 PM Tom_L: i've had it for years
01:54 PM Tom_L: been using it mostly as a testbed for lcnc configs
01:55 PM gloops: lots of cheap old mills around here atm, but im on with other things
02:32 PM ziper: hoo lee shit
02:32 PM ziper: i am so suprised that worked
02:33 PM ziper: put the liner in the dry ice, it fell right in the cylinder
02:45 PM phipli: https://www.youtube.com/watch?v=o4Ok0LQx0Uc
02:47 PM Tom_L: ziper a common way to press things on
02:47 PM Tom_L: gotta be quick about it though
02:47 PM cpresser_ is now known as cpresser
02:48 PM ziper: yah, but i didnt think the fit was close enough for it to actually work
02:48 PM Tom_L: you just don't wanna get it stuck halfway in :)
02:48 PM ziper: phipli, how much does one of those machines cost
02:49 PM ziper: i was so suprised that the rag i was holding it with got caught on the lip and had to press it in real quick
02:49 PM phipli: no idea
02:49 PM phipli: more than my house?
02:49 PM Tom_L: don't worry, you don't have room for it in your back yard anyway
02:50 PM phipli: heh
02:50 PM phipli: if I moved everything else out of the garage there might be room
02:50 PM phipli: I have a weird "two in line" garage
02:50 PM Tom_L: i would get bored running a machine like that
02:51 PM Tom_L: imagine how many hours go into that
02:51 PM ziper: put it on power feed and leave it, haha
02:51 PM phipli: yeah
02:51 PM Tom_L: you'd have to change cutters mid cut too though
02:51 PM phipli: and it is working reasonably hard at it
02:51 PM phipli: nice bright coloured swarf
02:52 PM Tom_L: looks like a govt crew running it. 3 watching, 1 working
02:52 PM phipli: :)
02:52 PM phipli: open day?
02:55 PM hazzy: phipli: That vid pops up here about once every three months or so :)
02:57 PM hazzy: They have some lathes about that size at the Siemens Charlotte NC Energy Hub
02:57 PM gloops: bearing ordered sunday morning in UK - dispatched already
02:57 PM Tom_L: hazzy with updates? maybe it's still cutting the same part
02:57 PM gloops: screws ordered from china 3 week ago - still not dispatched
02:58 PM gregcnc: qualitybearingsonline?
02:58 PM hazzy: They came off a navy ship build in the 40s. They put modern CNC controlls on them and use the to make state of the art nuclear steam turbines
02:58 PM gloops: bearingoptions greg
03:01 PM gregcnc: I used quality recently, they had the best price anywhere for a 7003 P4 pair
03:08 PM gloops: well i could have got a better price but i only wanted 1 for the time being, for experimental purposes
03:09 PM gloops: there is someone selling off a few odd large bearings at £1 in the UK, like expensive bearings, only got 1 or 2 of each left though
04:02 PM phipli: how large?
04:05 PM JT-Shop: phipli: just about got the python program done, maybe in the morning I'll finish it
04:05 PM JT-Shop: just need to add the manual override inputs
04:06 PM phipli: excellent :)
04:12 PM JT-Shop: so much easier to program it than the nano
04:13 PM phipli: do you use a text editor, or a full IDE?
04:14 PM JT-Shop: just a text editor
04:18 PM JT-Shop: I wonder how tolerant the inputs are on the Rpi
04:20 PM malcom2073: JT-Shop: Not very
04:26 PM JT-Shop: should I put some strong pull down resistors on the inputs?
04:26 PM JT-Shop: tolerant to noisy motors
04:32 PM jthornton: phipli: where I'm at so far http://paste.ubuntu.com/25797116/
04:32 PM gloops: phipli cant remember the range now, some 70mm inside diameter
04:56 PM Deejay: gn8
04:59 PM JT-Shop: goodnight
05:08 PM Tom_L: i forgot where to change units in sw...
05:09 PM Tom_L: found
05:17 PM JT-Shop: what's your temp over in ks tom
05:18 PM Tom_L: awesome
05:18 PM Tom_L: 70F
05:18 PM JT-Shop: 67F here, you didn't get that cold front?
05:18 PM Tom_L: not yet
05:19 PM JT-Shop: it's 50's just a bit west of us
05:19 PM Tom_L: it's been calm and sunny all day
05:19 PM Tom_L: we don't get many of these
05:20 PM Tom_L: friggin pdf. gives tolerances but not dimensional data for these chinese rails far as i can see so far
05:20 PM JT-Shop: gotta love that
05:20 PM Tom_L: or it's scattered all over the place
05:22 PM Tom_itx: http://www.hiwin.com/pdf/linear_guideways.pdf
05:22 PM Tom_itx: 17k
05:22 PM Tom_itx: grabcad had some models
05:24 PM Tom_L: even the bolt centers would be nice to know
05:27 PM Tom_L: ah hah maybe i found something
05:36 PM JT-Shop: what are you working on?
05:36 PM Tom_L: just drawing up something in my head
05:36 PM Tom_L: mill layout
05:37 PM Tom_L: thought about 2" sq tube for the frame for a little bigger than sherline mill
05:38 PM Tom_L: non gantry style
05:40 PM * JT-Shop tries another brand of ip poe camera after giving up on sv3c cameras lol
05:40 PM JT-Shop: hikvision is still rock solid
05:41 PM JT-Shop: https://www.amazon.com/gp/product/B0747HDRNL/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
05:43 PM malcom2073: I've been thinking about figuring out how to make a decent waterproof case for the pi+camera, be a decent IP camera with wifi
05:43 PM malcom2073: Case to be cheap as humanly possible
05:44 PM Tom_itx: https://www.hammfg.com/electronics/small-case/development-board/1593ham-rasp
05:44 PM Tom_L: probably not waterproof
05:44 PM malcom2073: gg hammond
05:44 PM malcom2073: Yeah doesn't look it
05:45 PM * JT-Shop wanders inside now
05:47 PM Tom_itx: http://www.makeuseof.com/tag/5-ways-to-ruggedise-your-raspberry-pi/
05:48 PM malcom2073: Nice
05:48 PM malcom2073: only the first is waterproof though
05:48 PM Tom_L: right
05:48 PM malcom2073: Wonder if it would overheat in it
05:49 PM JT-Shop: lol some bolts and wood
05:49 PM Tom_L: rubbermaid or tupperware also
05:49 PM malcom2073: My last car had its ECU in a tupperware bin heh
05:50 PM Tom_itx: http://fkeel.blogspot.de/2011/06/underwater-ir-webcam.html
05:50 PM * Tom_itx snickers
05:50 PM Tom_L: good ole silicon
05:50 PM malcom2073: heh
05:51 PM malcom2073: Erm, isn't water opaque to IR?
06:08 PM Loetmichel: malcom2073: hihi, tupperware is at least totally waterproof
06:08 PM Loetmichel: as long as you sealed al the wire holes
06:08 PM malcom2073: Loetmichel: Nope, it was mostly for short circuit protection
06:10 PM Loetmichel: as the ECU of my BMW is inside the passenger compartment (above the pasenger side foot well) there is no need for it to be waterproof
06:10 PM Loetmichel: ... at least in factory condition... the amount of water that seeps in at any rainy day now is frightening though ;)
06:11 PM malcom2073: Heh, this was built out of breadboards and random wires
06:12 PM malcom2073: It was a mess
06:29 PM Wolf__: just dont do something like this to waterproof electronics https://i.imgur.com/4H40TWQ.jpg lol
06:39 PM phipli: night folks
08:32 PM XXCoder: hey
08:32 PM XXCoder: what company tend to do cat6 contract installs?
08:33 PM Tom_L: electrical contractors
08:34 PM XXCoder: ok
08:34 PM XXCoder: someone commented on special cat6 cables
08:34 PM XXCoder: cat6 vpe or something?
08:36 PM XXCoder: STP probably
08:37 PM XXCoder: sftp seems best type
09:53 PM Valen: is there any paticular reason to do anything over the baseline?
09:53 PM Valen: XXCoder: ?
11:41 PM XXCoder: hey Valen
11:42 PM XXCoder: yes, Valen videophone latency
11:42 PM XXCoder: my videophone hs no wifi support also
11:50 PM Valen: the grade of cable will not affect videophone latency in the slightest
11:50 PM Valen: I mean 100mbit would be plenty for that paticular application, generally 10mbit would suffice
11:52 PM XXCoder: sure but what about 20 years later?
11:52 PM Valen: It'll still be the same?
11:53 PM Valen: all the other bits and bobs on the cables are to handle external interference, cat 5e can run gigabit over like 70 meters
11:53 PM Valen: cat 6 is a small enough price premium to warrant putting it in "because why not"
11:54 PM Valen: fancy pants cat 6 or cat 7 without a paticular reason isn't going to net you any gain
11:54 PM Valen: if you want "20 years" future proofing then run optical fibre and put a media converter on each end if your feeling keen or buy gear with SFP's in it
11:54 PM Valen: 10gbe over copper has very short runs over any grade of copper
11:56 PM Valen: my mistake looks like cat6A can run 10gbe over 100m
11:56 PM Valen: for roughly double the price of cat6
11:57 PM XXCoder: we may well end up with just cat6
11:57 PM Valen: how long is the run?
11:57 PM XXCoder: basic sheilded twist type
11:58 PM XXCoder: oh severial places, my room, mom's my bro's and his sons and 2 living rooms
11:59 PM Valen: distance
11:59 PM Valen: meters
