12:21 AM IchGucksLive: morning from germany
12:24 AM IchGucksLive: fog thick view below 50meters
12:24 AM IchGucksLive: gloops: are you making a massiv tank building cnc
12:24 AM gloops: wouldnt call it a tank hehe
12:24 AM gloops: i want it to be robust
12:25 AM IchGucksLive: its only as rubust as your leadscrew can take
12:26 AM IchGucksLive: if you go rackpinion like T10 you can add force but not on 1605
12:26 AM gloops: gantry total will be about 60kg
12:26 AM IchGucksLive: i got 800kg running
12:26 AM gloops: see, mines a lightweight
12:27 AM IchGucksLive: Why did you went gantry do you got large workpices
12:27 AM gloops: 800kg gantry? thats the best par of a tonne
12:27 AM IchGucksLive: stable mashines move worktable
12:27 AM gloops: not that large about 1200x900
12:28 AM gloops: 1200 is too much to move the table
12:28 AM gloops: it will be built by next week anyway
12:28 AM IchGucksLive: ok you know best
12:28 AM gloops: space - you need 2400 to move a 1200 table
12:29 AM IchGucksLive: i only go 900x600 on screw
12:29 AM gloops: well, im hoping it will be ok, 2 screws on the x
12:29 AM gloops: it WILL be ok, it might be slower than i hoped for
12:30 AM IchGucksLive: 3Nm on timingbelt
12:30 AM gloops: ill have 6Nm on x, 3 on y and z
12:31 AM IchGucksLive: direct drive
12:31 AM gloops: no, im going to make it go faster
12:32 AM IchGucksLive: ok its up to you
12:33 AM Contract_Pilot: Long day off to bed
12:33 AM IchGucksLive: GN8 Con
12:35 AM IchGucksLive: 140 emails 8hr it is getting bad
12:35 AM gloops: its a days job to reply to those
12:36 AM IchGucksLive: im short of deleting all interface Videos
12:36 AM IchGucksLive: as i cand contact cmorney and the 7i92 isent provided by pncconf
12:37 AM IchGucksLive: to many nonparport users
12:38 AM IchGucksLive: off till later got to mount the proxxons today
01:21 AM archivist: 600k views and about 5 comments for me :)
01:26 AM CaptHindsight: archivist: do you recognize that Bridgeport No 1A from a few hours ago?
01:27 AM CaptHindsight: https://www.ebay.co.uk/itm/Milling-Machine-made-by-Bridgeport-240v-single-phase/272932613450
01:30 AM archivist: 10 miles from me
01:31 AM CaptHindsight: is it related to the Bridgeports made in the USA?
01:32 AM CaptHindsight: Scottish knockoff? Licensed design made by someone else? Parallel universe?
01:32 AM archivist: Adcock & shipley in Leicester became the local Bridgeport, started buying the add on then were making local copies under licence
01:33 AM archivist: later became UK subsidiary of bp
01:33 AM * gloops checks the secret hole under the floorboards
01:34 AM CaptHindsight: archivist: what year do you think its from?
01:34 AM archivist: the earliest I have seen in the UK
01:34 AM gloops: nah, are you having a go at it archivist?
01:35 AM archivist: I have an Adcock & Shipley horizontal
01:35 AM archivist: dont have space or transport at the moment
01:36 AM archivist: I wonder if AS also distributed whole Bridgeports at the time
01:36 AM gloops: id have it for nowt, like it is now, really though got enough to do atm, i might look for a mill next year
01:37 AM gloops: its got to make 200+
01:39 AM CaptHindsight: circa WWII or postwar?
01:39 AM gloops: before i think
01:39 AM archivist: 20's?
01:40 AM archivist: by war time AS were making the thing I have
01:40 AM CaptHindsight: before the series 1's
01:40 AM CaptHindsight: or before they incorporated and starting casting them
01:40 AM archivist: that is an old belt drive
01:41 AM archivist: is it the BP add on head on something else though
01:42 AM gloops: that is a fair old pulley, would cut great
01:42 AM CaptHindsight: they started working on a hedge clipper in 1928
01:43 AM CaptHindsight: http://www.fundinguniverse.com/company-histories/bridgeport-machines-inc-history/
01:45 AM gloops: my lathe has a big pulley and flat belts, its great with the inertia, but really its a lot of tackle to turn a chuck
01:46 AM CaptHindsight: maybe a BP head on an older machine
01:46 AM CaptHindsight: non-heads parts from pre 1930's
01:46 AM CaptHindsight: head from later
01:47 AM gloops: i think that angle iron fram was made later
01:47 AM CaptHindsight: anyway, I'm off to catch Z's
01:47 AM gloops: some kind of bastardisation of different things
01:47 AM archivist: the model C head was sold for a while 32- when the mill came out
01:50 AM archivist: http://www.lathes.co.uk/bridgeport/img6.gif
01:51 AM Deejay: moin
01:53 AM archivist: could be this head on an old base http://www.lathes.co.uk/bridgeport/img99.gif
02:00 AM gloops: looks like it, i thought there was a cover missing off the front but maybe not
02:01 AM gloops: if you bought it i could help with transport - although so close you could probably get a local man and van for not so much
02:02 AM archivist: but where would I put it!
02:02 AM gloops: not exactly a table top item
02:03 AM archivist: small garage with CMM, Southbend lathe, Schaublin lathe, Bechler lathe and the Adcock & Shipley and a drill and bench centre and filing machine and other stuff
02:04 AM gloops: it would be bizarre to cnc that, all those wheels and belts wirring, and computer control
02:04 AM archivist: and another drill
02:04 AM archivist: it is an anteeeeek bitsa
02:05 AM gloops: but probably cuts better than a new £1200 mill from machine mart
02:09 AM archivist: I need more space, kitchen has 2 lathes and the hobbing machine, small bedroom the 5 axis mill
02:09 AM gloops: lol
02:10 AM archivist: lounge had the electronics :)
02:11 AM gloops: in our first house the bloke over the road was a bit of a biker, the council came to do some repairs on his house - council worker went in to have a look - came out crossing himself in a religious way - was a norton commando in bits in the bedroom, amongst other things lol
02:14 AM archivist: I did some crank work on my Norton on this table in the dining room
02:15 AM archivist: I met a local who hade many bikes in his house, and pianos and an engine behind the sofa
02:17 AM gloops: these showroom houses are ok to look at, but what do they actually do in them
02:17 AM gloops: they have a state of the art kitchen and mostly eat delivered pizzas
02:19 AM archivist: I was a TV repair man in the 1970's seen a huge variety of houses, the bare ones are the odd ones out
02:21 AM archivist: doing a window job in a house in the last couple of years, house nearly bare white carpet, new puppy craps in the middle of the lounge :)
02:27 AM gloops: well, better check these measurements, with the chain drive it was ok - chain just fit any sizes, this time stuff actually has to fit heh
04:29 AM XXCoder: I don't know why anyone wants white rug.
04:29 AM XXCoder: I once owned white car, and that was awful, awful mistake. Never again.
04:30 AM XXCoder: I bet if I'm standing on black rug, and few feet away is white rug and I pour wine... wine would curve away from black rug and stain white rug.
04:44 AM sync: white cars are not so bad if you don't care about the look
04:48 AM XXCoder: I suppose
04:48 AM XXCoder: I normally dont
04:48 AM XXCoder: but it becomes a floating green scum
04:48 AM XXCoder: so yeah for some reason white is extra bad on that
04:49 AM archivist: we were cleaning the pumping station a few weeks back and someone said I bet we all do more cleaning here than at home
04:51 AM XXCoder: interesting comment from that person
04:55 AM XXCoder: I wonder what prompted that
04:55 AM archivist: pumping station is a museum for public, my house is not
04:56 AM archivist: and bunch of blokes who let the wives do it at home
04:58 AM jthornton: morning
04:58 AM XXCoder: dang
04:58 AM XXCoder: compserve just closed their forums
04:58 AM XXCoder: its from dialup days
05:01 AM archivist: that means my old linux CDROM howto has bit the dust
05:02 AM XXCoder: lol
05:03 AM XXCoder: I had redhat book and cds
05:03 AM XXCoder: it was in days redhat was just a distro not business distro
05:03 AM archivist: mine dated from ygdrasil
05:03 AM XXCoder: it sucked but then it wasnt designed for user back then but more for servers and such
05:39 AM Tom_L: morning
05:39 AM XXCoder: yo
05:40 AM XXCoder: man I love this old tony jokes
07:04 AM jthornton: yuck raining today
07:05 AM XXCoder: heh havent had a non-rainy day for while. though today was driest so far. I could actually see road paint lines
07:08 AM jthornton: we just had a butt load of leaves fall off so what a mess on the deck with wet leaves
07:14 AM kraegar: anyone used an RPI for a gcode sender & have recommendations? looking at CNCjs, looks decent.
07:14 AM kraegar: setting up a first CNC, want a web based / pi based control if possible. have spare pi's
07:15 AM archivist: pi is a bit starved of resources for good cnc
07:17 AM archivist: and define "gcode sender", not how linuxcnc works
07:18 AM kraegar: sorry, that wasn't a linuxcnc specific question. You all just have the most active CNC channel, so was hoping for some input. :)
07:18 AM kraegar: Have a Shapeoko3 coming, was hoping to glue a pi to the side of it, so to speak.
07:19 AM kraegar: Can hunt for a more appropriate channel if I need to. Totally new to CNC
07:19 AM archivist: use linuxcnc and pc, and get a better machine with more abilities
07:20 AM archivist: it has been squeezed in a pi by a few but not mainstream
07:21 AM kraegar: I'll look into that route, thanks
07:23 AM CaptHindsight: cnc machines that can easily kill have their controls mounted at arms reach
07:25 AM archivist: not remotely usually
07:25 AM kraegar: I planned to stay near it, just didn't want to dedicate a PC to sitting there if a pi would suffice.
07:25 AM kraegar: it will have an e-stop button as well
07:27 AM CaptHindsight: it's lots of work to build a stable system for the Rpi...
07:27 AM archivist: with linuxcnc you have the option of proper servo operation with feedback
07:28 AM archivist: dunno if servo has been done on pi with linuxcnc
07:28 AM CaptHindsight: the distros for it tend to be broken with magic tool chains
07:30 AM CaptHindsight: the Rpi Ethernet is over USB so unsuitable for real time
07:32 AM CaptHindsight: feel free to build something stable for it
07:33 AM gloops: you only need an old xp era box really for general hobby/moderate production stuff
07:34 AM gloops: memory, hard drives, that kind of stuff is very cheap
07:36 AM kraegar: I can dig up a pc. will have to buy a monitor most likely.
07:37 AM sync: I wonder if linear motors would make a difference in a 3d printer
07:39 AM gloops: a bit stuck for 9 inch of channel, got 1 bit to much and something is welded to it already - inside the channel
07:40 AM gloops: i never thought i might want to get it off one day when i welded it
07:40 AM gloops: 1 bit to match
07:55 AM CaptHindsight: sync: they would drive the price up
07:57 AM CaptHindsight: I use linear servos with inkjet deposition all the time
07:59 AM sync: no shit, but other than being expensive
08:14 AM JT-Shop: dang least little sprinkle and I loose internet
08:40 AM miss0r: Hello o/
08:53 AM IchGucksLive: hi
08:53 AM IchGucksLive: NativeCam
08:54 AM IchGucksLive: Features
08:54 AM the_wench: NativeCAM https://github.com/FernV/NativeCAM
09:17 AM IchGucksLive: Does anyone know if i can install Nativecam on 12.04
09:21 AM JT-Shop: lol Solidworks resource monitor is driving me nuts lol
09:21 AM miss0r: I'm thinking about buying some chinesium parallels. Can you recommend any?
09:23 AM miss0r: I've been using these shop made ones forever. I would like some of thoes slim ones
09:24 AM gloops: well my estimation of america engineering just went up a bit
09:25 AM gloops: the old walker turner just piddled its way through a few holes in 20 mm plate, very nice drill
09:25 AM gloops: https://postimg.org/image/47bxvhg57/
09:25 AM miss0r: Impressive
09:26 AM miss0r: One would not think that looking at the drill :) How large was the predrill? :=
09:26 AM gloops: you know when you just get the feel that you are using something quality
09:26 AM gloops: no predrill, theyre only 8mm holes but first time i used it
09:27 AM miss0r: That is pretty good :]
09:27 AM gloops: it will do me
09:27 AM miss0r: I use a Hilti 22volt cordless drill/"screwing machine" at work. That machine have been abused for 8 years now. And it still goes strong. I've even used the hilt as a hammer in a pinch
09:28 AM miss0r: The batteries are starting to show wear now, thou
09:28 AM gloops: had a few hilti drills, they are good
09:28 AM miss0r: Yes. But they are expensive as frig
09:29 AM gloops: well they are more expensive, but if youre making money from it and cant be let down
09:29 AM miss0r: True
09:30 AM gloops: it isnt more expensive if youre out on a job miles away and your cheap drill gives up
09:30 AM miss0r: When it comes to drill presses, I put my trust in the lovely swedish people! :) Strands and Arboga is the way to go, in my humble opinion
09:30 AM gloops: never used one, i can believe it though
09:30 AM sync: we had alzmetall
09:31 AM sync: they are okay, but not worth the price people want for them used
09:31 AM miss0r: I can't speak for the newer models, but the 80's and 90's models are exeptional
09:31 AM gloops: i got this for £50 yesterday - mainly because it was so local on ebay and i knew they were supposed to be decent drills
09:31 AM miss0r: gloops: How do you change speeds on that one?
09:31 AM miss0r: sync: i don't know that one
09:32 AM gloops: miss0r - pulleys on the top, 12 speeds, the motor slides back and forth to tension the belt
09:32 AM IchGucksLive: Does NativeCam only work with gemoccapy
09:32 AM gloops: 70 year old about lol
09:32 AM IchGucksLive: i ony use axis
09:33 AM miss0r: I was afraid you'd say that. I've sworn off the belt driven ones(atleast the ones where you change speed with the belt). I don't change the speed enough.
09:33 AM gloops: not used nativecam yet ichs, i intend to sometime
09:33 AM miss0r: i.e. because i'm lazy i'll find a middle ground for a drill procedure and run too slow on the small drill and too fast on the larger ones.
09:34 AM gregcnc: I have to make some collet nuts for the Arboga. I finally modified some MT3 holder to be compatible.
09:34 AM gloops: ill mostly leave it on the lowest speed, i dont use a drill that much, my other one has been on the blink for a while i cant be messing about with it atm
09:35 AM miss0r: gregcnc: What model arboga?
09:36 AM gregcnc: EM825
09:37 AM miss0r: Nice :) It looks like the 2508 I used to have. Same retaining nut for the MT3 I suppose?
09:38 AM gregcnc: I think there were two types of nut. holder has a 2mm wire ring on it
09:38 AM miss0r: gloops: I used to have one of thoes imported ones that a local company slaps their own name on. It was with belt speed change. Horrible garbage
09:39 AM miss0r: gregcnc: I bought one of thoes MT3-er25 holders and turned a groove in it. Then I made a C-washer that fit in there.
09:40 AM gloops: yeah ive had a few things that were badged with what used to be quality marques, obviously made in china these days - useless
09:40 AM gregcnc: I made some wire rings. Added a facing holder to take 40mm insert head.
09:42 AM miss0r: Thats a bit big on that machine?
09:42 AM gregcnc: yeah it can only handle light loads facing, I work mostly aluminum
09:43 AM gregcnc: it beats facing with a 12mm endmill
09:43 AM miss0r: Considered a fly cutter?
09:44 AM gregcnc: 4 inserts
09:46 AM IchGucksLive: is Fern the Developer of nativecam here
09:47 AM miss0r: gregcnc: I'm just thinking - As you can only do a light cut anyway, it doesn't make alot of sense to me using a big indexable facemill. You might as well use a flycutter with a large radius :)
09:48 AM gregcnc: Fly cutter was worse.
09:48 AM gregcnc: I hate fly cuters in fact
09:48 AM * miss0r is beginning to wonder if something else it up with that arboga :]
09:49 AM miss0r: Hows the state of your spindle bearings?
09:52 AM gregcnc: The column just isn't very rigid for side loads. Finish is fine, and so is power. I don't use it much other than drilling tapping and facing. When I do precise milling it seems fine.
09:55 AM miss0r: I never found the column om mine very rigid either. But It could handle a 50mm radius on a flycutter, even doing light passes on steel. It gave pretty good results
09:56 AM miss0r: Do you have powerfeed on that thing? (I ended up converting it to LinuxCNC, with a bunch of steppers'n ballscrews)
09:56 AM gregcnc: no power feed
09:57 AM miss0r: Well. Its still a very versatile machine :) I miss mine sometimes
09:59 AM gregcnc: Yes I do like it. Just need to make tooling easier to work with.
09:59 AM gregcnc: and 400USD plus a new VFD was fair
10:04 AM miss0r: Absolutly
10:04 AM miss0r: I sold mine for just under 2000USD, converted to linuxCNC
10:31 AM archivist: miss0r, that was a good profit!
10:31 AM archivist: I have a good memory :)
10:32 AM miss0r: Considering I bought it for a 24-pack of beer and restored it myself, yeah. (not if you calculate time as money, thoy ;) )
10:40 AM IchGucksLive: im not getting this to work on 12.04
10:43 AM IchGucksLive: no gladeinterface glade is installed
10:54 AM gloops: gantry nearly done
10:55 AM gloops: but first im going to sand it down and primer it, ive got 2 colours, white or dark grey
10:56 AM miss0r: pics?
10:56 AM gloops: not took any
10:56 AM gloops: still in parts to be welded but that wont take long
11:02 AM archivist: pics or it didnt happen
11:03 AM gloops: ill post some pics another time, its only a few bits of box section, cunningly assembled though if i say so myself
11:04 AM miss0r: Looking forward to it then ;)
11:17 AM gloops: the real hurdle is going to be rotating ballnuts
11:18 AM archivist: no rotating nuts, its painful
11:19 AM gloops: it is on a lathe that was probably first delivered on a horse and cart
11:25 AM gloops: the entire concept of the machine hangs in the balance over this one component
11:26 AM JT-Shop: rotating nuts can be painful
11:28 AM pcw_home: oww
11:39 AM cradek: archivist: http://timeguy.com/cradek-files/emc/IMG_20171114_210824.jpg
11:40 AM cradek: archivist: I thought these were one piece, but it turns out I have the center and also a collet that matches the tailstock
11:40 AM archivist: win win
11:41 AM Contract_Pilot: Morning....
11:41 AM Contract_Pilot: Coffee, Coffee, Coffee!!!
11:41 AM archivist: cradek, better look after that at nearly 500 dollers worth
11:42 AM cradek: hahaha
11:42 AM cradek: $500.25
11:42 AM archivist: scrape the rust off
11:43 AM gloops: leave the rust on youre scraping the charm off it
11:43 AM Contract_Pilot: Seen this posted on a forum somone will snag it up.... fast
11:43 AM Contract_Pilot: https://nashville.craigslist.org/for/d/jet-1340-lathe/6384110194.html
11:43 AM Contract_Pilot: 50.00 hahaha
11:44 AM archivist: cheap for a set of castings
11:44 AM Contract_Pilot: Yep be a good base... i got a 12X36
11:45 AM gloops: 1800lbs - surely worth more than 50 for scrap
11:45 AM Contract_Pilot: Depends i think steel is low right now
11:45 AM archivist: cost of getting it to scrap yard as well
11:45 AM gloops: hmm, yeah off the bottom but still low price
11:46 AM Contract_Pilot: Yep...
11:46 AM Contract_Pilot: I cannot wait till this weekend I hope i get to play with my lathe...
11:47 AM gloops: there isnt that much missing there, got saddle and tailstock
11:48 AM Contract_Pilot: What i did with my 12X46 was part it out after the conversion
11:48 AM Contract_Pilot: 12X36
11:49 AM JT-Shop: hmm my Samson is a 16 x 60, if you take the gap bed out it swings 24"
11:49 AM Contract_Pilot: Waiting on Bonneville Power tech... I opted in to the heatpump data logger program
11:50 AM Contract_Pilot: http://www.stevenrhine.com/?p=2311
12:00 PM Contract_Pilot: Ok, off to go sweep the mud up on street again done want the county after me for all the mud.
12:26 PM miss0r: I LOVE sending bills to people... Sadly I don't get to do it very often :/
12:29 PM JT-Shop: For once I'm overloaded with work and they want more lol
12:29 PM miss0r: Please do share :P
12:30 PM JT-Shop: let me know next time your in Swamp East Missouri
12:31 PM miss0r: I will add your shop to my planned US tour ;)
12:32 PM miss0r: lol, closest i've been to missouri is louisiana.
12:33 PM miss0r: Let this be known: should anyone find them self in the northern parts of Sealand, Denmark - I will gladly give a shop tour and a cup of coffee ;)
12:34 PM archivist: who is paying the train fare
12:34 PM miss0r: JT-Shop: What do you do market yourself? I am seriously falling short on that area
12:34 PM miss0r: archivist: if you are already in said part of Denmark, I will pay the rest :]
12:35 PM archivist: hehe
12:36 PM miss0r: you can go from one end of sealand to the other for under 10
12:37 PM archivist: the other sealand https://www.sealandgov.org/about/
12:39 PM miss0r: archivist: to be more precise: https://en.wikipedia.org/wiki/Egedal_Municipality
12:40 PM miss0r: it is basically the size of a medium Texas ranche :P
12:43 PM gloops: strange design - https://www.ebay.co.uk/itm/19th-cent-German-high-precision-metalwork-lathe-Von-Pittler/302521563210?
12:43 PM archivist: a third of the municipal area I am in https://en.wikipedia.org/wiki/East_Staffordshire
12:44 PM archivist: ew pittler
12:44 PM IchGucksLive: figting with nativecam
12:45 PM miss0r: haha... I call the "high precision" into question
12:45 PM archivist: I think some clockmakers used them
12:45 PM gloops: whats that differential thing on the end
12:45 PM miss0r: IchGucksLive: What is the issue?
12:45 PM miss0r: gloops: Powerfeed vs manual
12:45 PM gloops: ahh yes
12:46 PM gloops: handraulic is useful - not sure thats a good place to be cranking from though
12:46 PM gregcnc: you don't crank it
12:46 PM gregcnc: the handle is fwd/rev feed
12:46 PM gloops: what do you do?
12:46 PM gloops: right i see
12:47 PM miss0r: Yeah. The axle in the botton is for manual feed, when you have it disengaged from the spindle
12:47 PM gloops: looks a bit overdesigned
12:48 PM miss0r: gloops: That being said, it looks nice as well :]
12:48 PM JT-Shop: miss0r: mostly I do work for the industrial park, I used to design and build automatic assembly machines for Briggs, now it's mostly smaller jobs
12:48 PM gloops: it does look in nice condition yes
12:49 PM JT-Shop: I do a lot of PLC programming for a plastic injection factory
12:49 PM gregcnc: http://www.lathes.co.uk/pittler/index.html some odd looking arrangements there
12:50 PM miss0r: I remember talking to you about this some time in the past. I also do alot of industrial stuff as an electrician (designing, building & programming industrial process lines'n such). But I am trying, atleast, to work my way towards being my own boss working from my small shop here :] I just need the clients
12:51 PM gregcnc: but the long feed handle at the tail of the bed seems of limited use?
12:52 PM archivist: on the leadscrew
12:52 PM miss0r: gregcnc: how so?
12:52 PM gloops: some early british lathes have that, leadscrew down the middle
12:52 PM miss0r: It seems to me it does exactly what a manual feed handle does?
12:53 PM gregcnc: how do you see what you're doing?
12:53 PM gloops: you turn there instead of the saddle
12:53 PM archivist: you have a long arm
12:53 PM miss0r: gregcnc: Its not like the lathe is 5 meters long :)
12:53 PM gloops: you had a boy in those days
12:53 PM gloops: yeah only 18 inch long
12:53 PM miss0r: haha
12:54 PM miss0r: The machinist was a guy with a large ruler, he used to smack the boys he had turning handles
12:54 PM miss0r: It was a better time...
12:54 PM gloops: faster boy, faster
12:55 PM archivist: only 20 miles from here
12:55 PM archivist: but mainly a display thing
12:56 PM gloops: they go mad on that - been cleaned up
12:56 PM archivist: probably will be a bun fight at the end
12:56 PM IchGucksLive: miss0r: coudt not create glade-xml object
12:57 PM IchGucksLive: miss0r: expected glade-interface got interface
12:57 PM IchGucksLive: it instals perfect
12:57 PM IchGucksLive: also the ini are perfect created but no tab
12:58 PM miss0r: did you install it with the .deb package?
12:59 PM IchGucksLive: yes
12:59 PM IchGucksLive: maybe a idee the wrong python-lxml
01:00 PM miss0r: I've never set it up with the .deb myself. Also, all the help I can search up online is for the non .deb installation
01:00 PM miss0r: Sorry, can't help you there then
01:01 PM IchGucksLive: the view is ok with standalone
01:02 PM IchGucksLive: but not in a tab
01:04 PM IchGucksLive: whow now mashine pc crashe
01:05 PM miss0r: :o
01:15 PM gloops: rare https://www.ebay.co.uk/itm/Lathe-Britannia-No-6-small-possibly-around-100-years-old-With-accessories/232551536811?
01:16 PM JT-Shop: I wonder how old this Starrett No 251 trammel bar is...
01:17 PM IchGucksLive: miss0r: i think i need a symbolic link
01:18 PM gloops: pretty old at a guess JT
01:20 PM JT-Shop: yea it doesn't have a letter behind the 251 and they are up to 251C now
01:21 PM JT-Shop: first time I've used it since I acquired it all those years ago when I bought the enco mill
01:21 PM miss0r: IchGucksLive: that is quite possible
01:22 PM miss0r: yesterday I burned out a brand new high quality tungsten carbide endmill in aprox 3 seconds :]
01:22 PM CaptHindsight: does the old lathes manual look like this: Cautions! when we useth a lathe, the following things might not but taketh most wondrous careth.
01:22 PM CaptHindsight: (1) keepeth not a chuck dudgeon attach'd by the chuck. Next, t flies at the moment of turning a lathe. (2) toucheth not the byte table into the rotating chuck. Not only a byte but the table 'r the lathe art did damage
01:22 PM miss0r: The mill started milling before the coolant had a chance to start. and the stainless I was working with hardened right the fsck up and burned the endmill in an instance
01:23 PM CaptHindsight: miss0r: happens pretty quick sometimes
01:23 PM Tom_L: better issue your coolant command sooner
01:23 PM miss0r: Yeah. I am usualy realy carefull with milling stainless...
01:24 PM miss0r: Tom_L yeah. it was a $65 endmill... so nexttime I will try to remember it - right up until i forget it again and have to pay the price
01:25 PM JT-Shop: that sucks when that happens, I used to laugh at electricians drilling stainless with the speed on max and as it turned blue...
01:26 PM miss0r: hehehe I still laugh at them :] until I discover they've borrowed the drill from me :O
01:26 PM miss0r: I'm one of very few electricians keeping my car stocked with cutting paste
01:28 PM gloops: Capt - pretty likely actually, the very early lathes would have been made by blacksmiths, not often very schooled fellows
01:28 PM miss0r: my colleague and my used to work alot at a steel plant, not far from here. There we were known as the stainless electricians :]
01:30 PM miss0r: Often seen TiG welding out own brackets'n stuff like that. Actualy a quite pleasant place to work
01:35 PM JT-Shop: I was working as an electrician building a water treatment plant years ago and everything was stainless, I stopped at the manufacturer of the enclosures to pick one up and they said it will be a while he is still polishing it... I walked back to the guy working on it and said if you could see where this box goes you would quit polishing right now
01:35 PM JT-Shop: it went in the lime pump building which was a horrible dirty place
01:43 PM JT-Shop: miss0r: one thing we did early on was to make some fliers and mailed them to all the local places that might need our services
01:53 PM IchGucksLive: no im not getting it
01:54 PM IchGucksLive: it starts not inside a ini
01:54 PM IchGucksLive: only as standalone
02:03 PM jym: Contract_Pilot: You could always add a video card and use those lenovo pc's
02:04 PM gloops: youll nail it Ichs
02:04 PM miss0r: JT-Shop: I think I do something like that. I should do something like that, that is
02:05 PM IchGucksLive: miss0r: where in gmoccapy is ncam located if i got it in the ii
02:05 PM djdelorie: one advantage of belt drive: you can push the gantry out of the way when the machine's off :-)
02:05 PM gloops: lol, i do that with my chain driven
02:05 PM miss0r: IchGucksLive: I have no idea, sorry :)
02:06 PM IchGucksLive: ok
02:06 PM IchGucksLive: then i give up
02:06 PM miss0r: Let me google it for you, hang on
02:06 PM IchGucksLive: i got about 800 students tomorrow non showing nativcam as i cand get it to work
02:06 PM IchGucksLive: BAD
02:06 PM IchGucksLive: so the good old dxf2gcode
02:07 PM IchGucksLive: 4hr of try is quite to mutch
02:07 PM IchGucksLive: im off BYE
02:07 PM gloops: use older version tommorrow?
02:07 PM jym: What is he having an issue with?
02:08 PM gloops: cant load nativecam
02:08 PM jym: ah
02:08 PM miss0r: damnit... I think I found a solution online for him to try
02:09 PM miss0r: He ran of in such a hurry
02:09 PM gloops: i think hsi email is on hos youtube blog
02:09 PM miss0r: meh. can't win'em all
02:09 PM gloops: wow poor typing lol
02:09 PM miss0r: undoubtfully he is offline now
02:10 PM miss0r: you still make more sense than present teenagers texting
02:10 PM gloops: he puts some hours in making those tutorials
02:10 PM miss0r: Yeah. I've actualy stumbled across some of his videos by chance earlier
02:49 PM gregcnc: capthindsight chuck keys https://www.instagram.com/p/BbbTtURgJSF/

03:29 PM JT-Shop: damm memory has gone up :(
03:29 PM andypugh: How do I tell if a random screw is 10-24 UNC or 3/16-24 UNC?
03:30 PM JT-Shop: they are the same no?
03:32 PM cradek: I've never heard of 3/16-24
03:32 PM cradek: is that even a thing? I don't have my book here.
03:32 PM gregcnc: JUST HOW ANCIENT IS IT?
03:32 PM djdelorie: OD? #10 is 0.190, 3/16 is 0.187? That's as close to "same" as I need :-)
03:32 PM JT-Shop: I think I have a box marked 3/16-24 somewhere
03:33 PM cradek: weird
03:33 PM djdelorie: #5 is 1/8 though
03:37 PM andypugh: This is my 1960s Harrison milling machine.
03:37 PM JT-Shop: https://www.grainger.com/product/GRAINGER-APPROVED-3-16-24-Stove-Bolt-with-Round-2XJ85?breadcrumbCatId=10753&s_pp=false&picUrl=//static.grainger.com/rp/s/is/image/Grainger/2EA55_AS01?$smthumb$
03:37 PM andypugh: It has a label saying “UNC” because it is from a time when Whitworth was still possible.
03:38 PM andypugh: Looking through the parts list I see a lot of N010 and no 3/16 so I will assume No10.
03:58 PM CaptHindsight: https://www.grainger.com/product/GRAINGER-APPROVED-3-16-24-Stove-Bolt-with-Round-2XJ85?breadcrumbCatId=10753&s_pp=false&picUrl=//static.grainger.com/rp/s/is/image/Grainger/2EA55_AS01?$smthumb$
03:59 PM CaptHindsight: the topic comes up often on auto forums
04:02 PM Deejay: gn8
05:00 PM malcom2073: Heh, close enough, like M5 and 10-32?
05:00 PM malcom2073: At my work they INTENTIONALLY mixed the two in an assembly.
05:02 PM gonzo_: evening peoles....
05:02 PM gonzo_: peoples
05:03 PM gonzo_: a fun mesa i/f card question for you all
05:03 PM gonzo_: (well probably mr PCW)
05:03 PM Tom_L: just ask
05:04 PM gonzo_: I have a 7i37 card, which I#m driving with an encoder o/p
05:05 PM gonzo_: the encoder is open collector o/p, so I'm driving the 7137 opto from 5v, and then through the encoder o/p
05:05 PM andypugh: I made a double-screw vice once (tiny one) that used two different sized screws with the same pitch on the same shaft. (one left-handed). It couldn’t have been assembled had the diamters been the same size.
05:06 PM gonzo_: get nice waveforms on the opto i/p, but on the output to the fpga card, I am getting narrower pulses than expected. to the point at which, at ~5khz, there is nothing at all
05:07 PM Tom_L: like jorgensen clamps
05:07 PM gonzo_: is there any known freq limit on these cards?
05:08 PM pcw_mesa: gonzo_ Yes the 7I37 is not very fast probabl 5KHz on inputs and maybe 2 KHz on outputs
05:08 PM gonzo_: pcw_mesa, thanks, that explains it.
05:09 PM gonzo_: thought I was going mad
05:09 PM pcw_mesa: its really intended for 5 --> 24V limit switch inputs etc
05:09 PM gonzo_: what is the limiting factor? the opto transistor capacitance?
05:10 PM gonzo_: that is mostly what I have on there
05:10 PM CaptHindsight: TechShop closes and files for bankruptcy yet post the info as a 4.5MB pdf file on a website
05:10 PM CaptHindsight: https://techcrunch.com/2017/11/15/techshop-shuts-down-all-u-s-locations-declares-bankruptcy/
05:11 PM pcw_mesa: the OPTOs are intentionally overdriven (low inout resistor high output resistor) so the output transistor saturates
05:11 PM CaptHindsight: "Membership was usually around $1,000 a year"
05:11 PM pcw_mesa: this makes them dependable WRT component drift but slow
05:11 PM synfinatic: new membership for a full year was $1500 w/ monthly installments
05:12 PM synfinatic: at least for my local TS
05:12 PM gonzo_: pcw_mesa, and the logic after the opto is high z I assume?
05:12 PM CaptHindsight: were they leasing all the brand new brand name equipment?
05:12 PM andypugh: Explains why Techshop Detroit kept trying to get me to join.
05:12 PM CaptHindsight: synfinatic: ^^
05:12 PM andypugh: It was a good setup.
05:12 PM synfinatic: dunno their cost model
05:13 PM CaptHindsight: sounds like bad management
05:13 PM pcw_mesa: gonzo_ yes, until the cable driving buffer
05:13 PM synfinatic: their website would have very limited info about the gear. "$1.4M worth of equipment"
05:13 PM synfinatic: "A tormach CNC"
05:14 PM CaptHindsight: how do you fund expensive machines without bringing in profit?
05:14 PM andypugh: Interesting to compare Techshop to the shambolic chaos of London Hackspace.
05:14 PM synfinatic: "If you build it, they will come"
05:14 PM CaptHindsight: makerspaces have enough fragmentation due to people not being able to get along...
05:14 PM CaptHindsight: and they mostly refurb older machines
05:15 PM synfinatic: I know the local TS pissed off a bunch of people with their "no weapons" policy which was really arbitrary and a bunch of people interested in making knives were told no
05:15 PM CaptHindsight: but then you need a few people that know what they are doing and for the members not to annoy them with stupid politics
05:16 PM gonzo_: pcw_mesa, Ok, that nails that issue then. I'll knock up a separate opto board for that encoder (spindle)
05:16 PM synfinatic: I was hoping to join sometime and take a bunch of classes... ¯\_(ツ)_/¯
05:16 PM CaptHindsight: "All scissors must have blunt ends"
05:16 PM synfinatic: i'll have to try a local jr. college i guess
05:17 PM CaptHindsight: the Makerspace in Chicago has so many juveniles that you couldn't leave your laptop unlocked our you'd return to find some prank on it
05:18 PM CaptHindsight: I wonder if they had similar problems
05:18 PM CaptHindsight: jr high with machines and tech equipment
05:21 PM CaptHindsight: i think some of the tech incubators around here are only $200/mo
05:26 PM CaptHindsight: starts at $145/mo https://mhubchicago.com/page/equipment-and-resources
05:31 PM andypugh: That’s an annoying web page. The sub-sections take you to pages with equipment photos that just go black when you mouse-over them. No click, no further details. That’s silly.
05:54 PM Contract_Pilot: Looks like this weekend is going to be a fun weekend.
05:56 PM Contract_Pilot: The street is clean enough if county complains f-them 6 hours cleaning the street in front of my house look better then the rest the hood....
05:57 PM Contract_Pilot: thankfull for the steady rain made moving the dirt and sand with the abckpack blower much simpler
06:05 PM CaptHindsight: andypugh: yes, you wonder who designed that site since it's for a tech incubator
06:06 PM andypugh: You have to clean your own sreets?
06:06 PM andypugh: (I know that in Germany you are legally responsible for clearing snow and ice from the pavement in front of your house)
06:09 PM CaptHindsight: andypugh: do you Brits celebrate Thanksgiving yet? Holidays seem to get commercialized everywhere
06:10 PM CaptHindsight: Thanks that those pesky Puritans left
06:10 PM MarcelineVQ: they probably celebrate it early, to commemerate the rabble heading off
06:10 PM MarcelineVQ: takes awhile to float that ocean
06:11 PM CaptHindsight: are there holidays to commemorate colonizing Australia?
06:13 PM CaptHindsight: Australia Day
06:20 PM andypugh: No, we don’t do Thanksgiving, but we do seem to have been infected with Halloween. And we get subjected to a wierd orphaned “Black Friday” too, now.
06:23 PM CaptHindsight: Black Friday is slowing down here since xmas shopping is moving from brick and mortar to online
06:26 PM roycroft: our liability laws make it undesirable to clear snow from one's sidewalk
06:26 PM roycroft: if i shovel snow and someone slips and falls on the pavement that i shoveled i can be sued
06:26 PM roycroft: but if i do not shovel it's an act of nature and i cannot be held responsible
06:27 PM roycroft: fortuantely it only snows once/year or so here, and the snow rarely sticks for more than a day, so it's not a big deal
06:47 PM CaptHindsight: andypugh: are the forks and ramps as flimsy?
06:47 PM Tom_L: what's wrong with that CaptHindsight?
06:47 PM andypugh: Fairly springy, yes.
06:47 PM Tom_L: it'll end up as scrap iron eventually anyway
06:47 PM Tom_L: i've seen those car lifts in tall garages before
06:48 PM Tom_L: 2 story car park
06:49 PM Tom_L: only thing i see there is load shifting
06:49 PM andypugh: We use these too. https://www.youtube.com/watch?v=1BzxqjUpAmM
06:49 PM CaptHindsight: I have a similar lift in my shop
06:50 PM CaptHindsight: rated for 7k lbs and is already bent
06:50 PM CaptHindsight: someone probably tried lifting a loaded truck
06:55 PM Crom: weeee
06:55 PM Crom: haven't fired up the mill in a week...
06:55 PM Tom_L: https://www.youtube.com/watch?v=ZqFaVi4E7e8
06:55 PM Crom: ugh have yet another 2 hoses leaking.... only 5 hoses left to replace
06:55 PM Crom: oil cooler hoses 2ea, throttle body warming water 1ea, heater valve to heater core, and return from heater core
06:56 PM Crom: I'll drive the Cadillac till the begining of the month...
06:58 PM andypugh: Tom_L: The recipients of that container are going to be _so_ impressed.
07:00 PM andypugh: Though I do like the tiny-wheel JCB.
07:05 PM enleth: the 4 gallon bucket of evaporust arrived today, I'm curious to try it out and see if I get similar results to Abom79's
07:09 PM MarcelineVQ: that's a fair shake of derustgoo
07:11 PM enleth: I'm tired of shitty rust removers and I trust Abom to not endorse a shitty product, so I went for the biggest container available around here to get the best price per gallon
07:12 PM enleth: besides, I have a couple big parts to derust
07:15 PM enleth: some dolt left the robot I bought outside in the rain at some point and it's got a couple slightly rusty parts
07:15 PM MarcelineVQ: that kind of shit is infuriating
07:16 PM MarcelineVQ: we got structural girders for a building and they had been trucked in such a way that they got road salt all over them
07:17 PM MarcelineVQ: what's your bot for?
07:21 PM hazzy: enleth: Evaporust is great stuff! I have almost used up my 5gal pail, need to get some more
07:27 PM hazzy: oops, netsplit?
07:34 PM enleth: MarcelineVQ: KUKA KR200, came from a Volkswagen factory, now it's going to do some plasma cutting and light milling, in addition to serving as a training machine
07:35 PM enleth: I got it for a bit less than scrap value because the previous owner was unable to fix despite having bought a bunch of spare parts and got frustrated with it
07:36 PM enleth: turns out he got spares for things that were perfectly functional and couldn't figure out a faulty servo drive
07:36 PM enleth: and a bad RAM module in the PC
07:38 PM enleth: now I have a working robot and a bunch of spares I can either keep or sell for more than it cost me to buy the whole thing with those parts
08:30 PM SpeedEvil: :)
08:43 PM Tom_L: https://www.youtube.com/watch?v=yU0ZKvEeZeM
09:44 PM hazzy: Tom_L: Must be a pain programing those machines, and trying to compensate for spring back, which would likely effect previous bends ....
10:20 PM Contract_Pilot: Dusting off my hal, post hal, and ini.
10:22 PM Crom: cnc pipe bending... Hmm, probably bend shy, the read angle then rebend as nessary
10:23 PM Crom: oe you get the angle to bend too, for material and have a tollerance...
10:23 PM Wolf__: do a test bend to get the spring back numbers
10:24 PM Wolf__: I have tube bending software that has spring back compensation built in
10:36 PM chopper79: Hello
10:37 PM hazzy: hello chopper79
10:38 PM chopper79: Mesa 7i76E TB4 connector pins 7 (Spindle -) and 8 (Spindle +) are for the direction signals to the VFD FWD and REV pins correct?
10:38 PM chopper79: hazzy: Hello, how are you?
10:38 PM hazzy: Tired, and you?
10:39 PM chopper79: first time hooking up a 7i76 to a huanyang vfd
10:39 PM hazzy: ah, let me see how I have mine set up
10:39 PM chopper79: I am exhausted myself. Trying to finish up a few wiring issues before my board comes in tomorrow
10:40 PM chopper79: I am so use to the 7i77 that this connection setup is not registering with me very well.
10:43 PM chopper79: Seems like the following is correct: TB4 connector Pin 1 = supply voltage (10v-) Pin 2 = VI on VFD, Pin 3 = supply voltage (10v+). Then you have Spindle - and Spindle + on TB4. The VFD has a FWD and REV, but need a refence form DCM (COM) to work. Where does that come from? Does the DCM go to TB4 Pin 7 and Pin 8 goes to the FWD pin on VFD?
10:44 PM chopper79: In 7 = PSindle - and Pin 8 = Spindle + on TB4 7i76
10:44 PM chopper79: *Pin 7
10:45 PM * Tom_L agrees because he doesn't know any different
10:45 PM chopper79: lol
10:50 PM chopper79: I feel that a relay needs to be involved to have FWD and REV. This is due to the 7i76 does not have a +/-10v out for the VFd to be driven.
10:51 PM Tom_L: on my sherline i used the stock motor driver and managed to get reverse
10:52 PM Tom_L: used it's inhibit signal to kill the driver while the relay was switching
10:52 PM Tom_L: to save contact wear
10:52 PM Tom_L: just enough time for the relay to switch and settle
10:52 PM Tom_L: watched on a logic analyser
10:53 PM hazzy: hmm, I am confused about how TB4 pins 7 & 8 (SPINDLE DIR- & SPINDLE DIR+) work
10:54 PM chopper79: same here
10:54 PM chopper79: Thinking that pin 7 goes to DCM on VFd anf Pin 8 goes to FWD on VFD.
10:55 PM hazzy: Maybe they just connected to Spindle - when false, and Spindle + when true?
10:55 PM chopper79: Not sure.... This is what I get for trying a different board configuration...haha
10:56 PM chopper79: TB4 Pin1,2,3 are simple enough. Pins 7,8 are the mystery ones for me. Need to find a awy to trigger FWD and REV on VFD and I believe thoses two pins do that, but need refenced to DCM on VFD
10:56 PM chopper79: in order to work
10:56 PM chopper79: somehow
10:57 PM chopper79: this is why I think a relay needs to be involved
11:01 PM hazzy: Are you using the spindle enable? or just spindle out?
11:01 PM chopper79: spindle out
11:01 PM hazzy: Well, then you could use enable for direction
11:02 PM hazzy: hmm, how would that help? haha
11:03 PM chopper79: Doing some more research and it looks like Pin 7 will go to DCM and Pin 8 goes to FWD. Now I am really thinking a relay will need to be involved for REV to work also.
11:04 PM hazzy: Use enable for rev,
11:04 PM chopper79: Relay in rest state triggers FWD and then when relay is energized it transfers Pin 8 to REV pin on VFD
11:06 PM hazzy: Yes, that should work, but since you are not using enable you basically have an additional output you could use for REV. Right? or am I not thinking straight?
11:07 PM chopper79: I agree, but would enable always activate start spindle in LCNC then?
11:08 PM chopper79: maybe not... wonder if I can assign pin 6 (Enable+) on TB4 in hal for REV and Pin 8 (spindle+)for FWD? I would need to link Pin 5 and Pin 7 together so they both see the DCM (gnd) on VFD
11:10 PM chopper79: Dont have a computer up and running to go into pnconfig and see if that is an option though.
11:10 PM * hazzy is playing with pnconfig
11:10 PM chopper79: I would think I could since pins 5,6 and pins 7,8 are nothing more then a opto switch I believe.
11:11 PM chopper79: Maybe I am wrong also and I can not configure it like that
11:12 PM hazzy: Does not seem like you can configure it in pnconfig, but I would think you could do it by hand
11:14 PM chopper79: Manual says the Spinena output is special as in when the analog output is enabled the spinena opto turns on. Wonder if that is refencing pins 5.6?
11:16 PM chopper79: If this is correct then I could not use it as a REV signal as when the analog signal enables pin 6 will turn on and also pin 8 so the VFD would get both FWd and REV signals at the same time. That is how I read it anyway
11:22 PM hazzy: Ok, looks like you are right that that will not work :(
11:24 PM hazzy: On my VFD (AD GS1) I can program it to use one pin for the direction, TRUE for FWD and FALSE for REV. Can you possibly do the same with the huanyang?
11:27 PM hazzy: Sorry, OPEN is FWD, CLOSED is REV
11:30 PM chopper79: good call... Looking in VFD manual and it appears that you can set the functions to be open FWD and close REV. If this is tru then problem solved.
11:32 PM chopper79: Thanks for chatting with me abotu this
11:32 PM chopper79: about
11:33 PM hazzy: Of course! I hope that works.
11:33 PM chopper79: I will wire up a pot tomorrow and some basic triggers with wires and check this idea out. If so then life go semi simple for a few hours
11:34 PM hazzy: Great, report on the result
11:34 PM chopper79: I will
11:35 PM * hazzy is thinking about hitting the hay, instead of debugging more python code
11:35 PM chopper79: Now its time to get some sleep. Work form 5am to 2:30 and then come to my shop and work to about 11-12pm everynight. One day I will be at my shop only
11:36 PM chopper79: Going to have to make the choice of keeping both incomes or going solo full time.
11:36 PM chopper79: Its breaking me down
11:36 PM hazzy: Those are long hours, but worth it if you can someday become your own boss
11:37 PM chopper79: Thats the game plan.... one step at a time. Running into questions like this make it frustrating though.
11:38 PM chopper79: I should not have simple questions about spindles at this point in the game. First 7i76 with a VFD, so I guess something new to learn.
