12:18 AM CaptHindsight: a/and
12:18 AM IchGucksLive: 25 burned deth in greec
12:18 AM CaptHindsight: fires up in Sweden as well
12:18 AM IchGucksLive: Letchy, if you are interestet my info YT channel on your board https://www.youtube.com/channel/UCmwhCL92ZQRSVqFe3jGwJSQ/videos
12:24 AM IchGucksLive: im off 2 garden BY
01:40 AM Letchy: Im still here
01:40 AM Letchy: Hi all from Australia
01:41 AM Letchy: mate come to Australia and see how hot things can get
01:54 AM CaptHindsight: a few more years and we'll have your weather over here and in the EU :)
01:54 AM CaptHindsight: Letchy: what are you working on?
01:59 AM Deejay: moin
02:02 AM Letchy: CNC hotwire for a veetal drone structure
02:02 AM Letchy: a big boy
02:02 AM Letchy: anyway im off, thank you all for your helpo
02:06 AM gloops: this weather is seriously depressing
04:05 AM IchGucksLive: hi al it is burning hot outside
04:05 AM IchGucksLive: gloops, weathere heat warining in UK
04:06 AM IchGucksLive: off 2 harvest weat
05:36 AM Tom_L: 75F Hi 92
05:37 AM Loetmichel: *HEYHOOO* Canopy Motors of the BMW convertible work again... Fuse in the trunk for the motors was totally corroded... filed it back to metallic state, Controller reset, works like a charm again, and faster tan before... now i just need a cheap original suspension, a new ABS pump and then it can go to the next roadworhty check wirhout failing (hopefully) :-)
06:30 AM miss0r2: Loetmichel: Keep in mind; that fuse will *never* be as good as it once was. It will corrode faster than ever now ;)
06:32 AM Loetmichel: miss0r2: temporary fix. i have new fuses at home
06:32 AM Loetmichel: it just refused to initialize the last week and i didnt know why
06:32 AM miss0r2: Good :] Once the sink is gone it a oneway road to corrosion ;)
06:33 AM Loetmichel: finding the culprit is half the problem solving
06:33 AM miss0r2: Yeah
06:33 AM miss0r2: I went to work on a CCCP branded lathe from 72 today
06:33 AM miss0r2: 1972*
06:33 AM miss0r2: Turns out a relay was burned out. It took me a while to locate :]
06:33 AM Loetmichel: i can imagine
06:34 AM miss0r2: atleast with cars you have a chance of getting the electrical drawings.
06:34 AM miss0r2: I suppose it is possible to get for this lathe as well, but I wouldn't hold my breath
06:35 AM Loetmichel: being an old 1999 BMW 318i convertible you can get EVERYTHING for it
06:35 AM miss0r2: sweet
06:35 AM Loetmichel: i even have the OBD plug and the software to read the controllers (ECU, ABS, Canopy, etc..)
06:36 AM Loetmichel: its just that all the convertible specific stuff is expensive as hell
06:36 AM miss0r2: hehe; i remember, not too many years ago, these plugs and software to go with it was impossible to buy with a regular salary
06:36 AM Loetmichel: you can get a used suspension for the staion wagon or the coupe no problem... convertible... good luck finding one.
06:37 AM Loetmichel: these days the plugs are dirt cheap. 120 eur with a better than original software from BMW
06:38 AM miss0r2: That is just crazy
06:38 AM Loetmichel: ptoblem is that the convertible has a special suspension because its 60kg heavier than the coupe...
06:38 AM Loetmichel: so it has different springs even if the mount points are identical
06:38 AM miss0r2: I remember a friend of mine buying a software package with a special plug'n converter for 16k eur back in the day for his auto shop
06:38 AM miss0r2: bah
06:39 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=16797
06:39 AM Loetmichel: tha plug is cheap. you can get it on ebay for a tenner
06:39 AM Loetmichel: but the sofware thats made for it is 120 eur... and comes with a plug as well ,)
06:40 AM miss0r2: My god that is small. The box he bought was 30x30x15cm ish
06:40 AM miss0r2: :]
06:40 AM Loetmichel: its meant for a notebook
06:40 AM Loetmichel: with a serial port
06:40 AM miss0r2: I see no excuse for me not to go out and buy one. I mean; I could safe a trip to the auto shop for the odd job
06:40 AM Loetmichel: not an USB/serial converter, doesent work ,)
06:40 AM miss0r2: I bought a toughbook a little while back - it has a serial interface :)
06:41 AM Loetmichel: yeah, just reading the error log of the ECU is usually 40 eur here
06:41 AM Loetmichel: 3 times that and you have paid for the plug
06:41 AM Loetmichel: and software
06:41 AM miss0r2: hell.. I should get one
06:41 AM miss0r2: Does it work with all cars? (I know little to nothing about these units)
06:42 AM Loetmichel: some do some dont
06:42 AM Loetmichel: this one on the pic is especially for old BMWs
06:43 AM Loetmichel: anything that has OBD2 standard plugs you can buy the cheap Wifi/BT thingys that plug in there and use your phone to read the errors
06:43 AM miss0r2: hah. I think I need to go read a bit before I actualy buy anything then :)
06:43 AM miss0r2: With my old '06 skoda octavia theres no telling
06:52 AM methods_: hey andypugh got a mention on dangerous prototypes
06:52 AM methods_: http://dangerousprototypes.com/blog/2018/07/23/assembly-instructions-for-the-stmbl-servo-drive/
06:53 AM methods_: his poor website is about to get hammered
06:56 AM Loetmichel: miss0r2: any car newer than 2000 for petrol engines and 2003 for diesels HAS to have an OBD2 plug in europe. so chances are good that your skoda can do OBD2
06:56 AM miss0r2: nice. I think i'll get one of those plugs then
06:56 AM Loetmichel: with a cheap 10 eur plug and a free app (i recommend "torque" on android)
06:57 AM miss0r2: but that the android app also 'reset' errors?
06:57 AM Loetmichel: yes
06:57 AM miss0r2: :o
06:57 AM miss0r2: What a time to be alive :D
07:09 AM methods_: http://phyzblog.blogspot.com/2018/07/be-careful-with-your-parabolic-mirror.html
07:09 AM methods_: lol
07:09 AM methods_: never leave your parabolic mirror in your car
07:16 AM Beachbumpete1: hehe that sucks
07:28 AM robotustra: yeah, don't leave transparent plastic bottles with water, they can burn the car also
07:35 AM Beachbumpete1: I would bet they could actually under the right conditions... Gotta smoke out those windows I guess ;)
08:57 AM Deejay: re
09:57 AM hazzy-lab: wb
10:32 AM IchGucksLive: hi all
10:34 AM IchGucksLive: did you guys see my crap cnc in basement milling Alu Wrenches
10:34 AM IchGucksLive: it is hardbreking and ear busting
10:42 AM Beachbumpete1: no
10:50 AM IchGucksLive: off till llater
12:02 PM roycroft: hi folks
12:02 PM roycroft: i need to make some parts that have awkward dimensions
12:02 PM roycroft: long and skinny
12:02 PM roycroft: they will be ~22mmx22mmx610mm
12:03 PM roycroft: i need to square all six sides, then mill features into two of the 22mmx610mm sides
12:03 PM roycroft: i'll need to mill features into the ends, too, but i can do that in a vice easily
12:03 PM roycroft: i'm not sure what would be the best way to fixture these parts
12:03 PM roycroft: the features i mill into the long sides will be through features, so i can't just clamp them down on the mill table directly
12:03 PM roycroft: any suggestions?
12:04 PM roycroft: the parts will be made of 6061, and i need a good finish - they will be anodized in the end
12:04 PM roycroft: i'm not even sure what would be the best way to square the long sides
12:04 PM jdh: make a holder?
12:05 PM Rab: Two vises?
12:05 PM roycroft: i thought about two vises
12:05 PM roycroft: they're so long though, that i wonder if that's enough support
12:05 PM roycroft: and i don't think i can come up with a third vise
12:06 PM Rab: Yeah, that form factor in 6061 seems like it would deflect in the middle.
12:06 PM roycroft: but a holder sounds like it might be a good plan
12:06 PM roycroft: and it could be self-tramming
12:07 PM methods_: you have prints of the parts?
12:07 PM methods_: might help with suggestions
12:07 PM roycroft: not yet
12:07 PM methods_: ah ok
12:08 PM roycroft: i have a first draft in autocad
12:08 PM methods_: well without knowing where the thru features are it will be hard to suggest
12:08 PM roycroft: i'll refine a bit and get back to you all
12:08 PM Rab: Maybe make a support sleeve out of steel angle, with cutouts for the clamping vise jaws and slots to clear your features.
12:08 PM gloops: use a router
12:09 PM roycroft: it's a jig for locating holes for european style cabinets
12:09 PM roycroft: so 3/8" through holes spaced 32mm apart
12:09 PM methods_: just use 2 vises with machinable jaws
12:09 PM Rab: Or, I guess, a steel plate between the workpiece and the table with pockets to clear the through features, and clamp everything to the table.
12:09 PM methods_: or 3 vises
12:10 PM roycroft: i was thinking about a couple pieces of rectangular bar bolted together at a 90 degree angle
12:10 PM roycroft: bolted down to the table
12:10 PM methods_: but it's alum so you can probably get away with just 2 vises and have some overhanging
12:10 PM roycroft: and then milled square
12:11 PM methods_: i'm assuming standard 6" vise jaws
12:11 PM roycroft: i need to talk to the anodizing outfit today, that reminds me
12:11 PM rmu: roycroft: superglue and a spoil-piece
12:11 PM roycroft: yes, the mill has 6" jaws
12:11 PM roycroft: tolerance of the 3/8" holes is fairly tight
12:11 PM roycroft: and i need to know how much to allow for the anodizing
12:11 PM roycroft: probably 0.001"
12:12 PM rmu: european cabinets with 3/8" holes sounds strange ;)
12:12 PM roycroft: the holes are sized for a router bushing
12:13 PM roycroft: the router bit will be 5mm
12:13 PM roycroft: the nice thing about the holder idea is that it would be easy to locate the parts - i need to make several of these
12:13 PM rmu: never tried it but could work https://www.nyccnc.com/super-glue-fixturing/
12:14 PM roycroft: folks use super glue to fixture parts on the lathe all the time
12:14 PM roycroft: i've not seen it used on a milling machine though
12:15 PM rmu: take oversize pieze, square it up, leave it oversize, glue it to table, drill holes (not through), flip, mill to size
12:17 PM rmu: glueing should be able to take 1N/mm² or more in shear-mode, add some clamps to prevent lifting
12:18 PM roycroft: i just received an email with the manuals for the bridgeport cnc mill i have access to
12:18 PM roycroft: the software is called dx32
12:18 PM roycroft: does that sound familiar to folks?
12:19 PM roycroft: boss dx32, from 1993
12:19 PM roycroft: i was told it was an early '80s cnc
12:19 PM roycroft: i guess it had been updated
12:30 PM IchGucksLive: hi
12:33 PM roycroft: hello
12:33 PM roycroft: another hot day here
12:33 PM roycroft: we have a heat advisory again
12:33 PM roycroft: upper 30s the high
12:36 PM IchGucksLive: folks todays alu mill with the Crap CNC
12:36 PM IchGucksLive: https://www.youtube.com/watch?v=ZWeWnic_Kvo
12:38 PM roycroft: is it an optical illusion or is that end mill flexing a lot?
12:38 PM Rab: "SORRY THe noice is Ear Breking" ...should be required disclaimer for all CNC videos.
12:39 PM IchGucksLive: it bends 0,4mm
12:39 PM sync: filmed with a potato
12:39 PM robotustra: Rab, my cnc is silent :)
12:40 PM robotustra: the film is about potato and with potato
12:40 PM robotustra: the film is about potato and filmed with potato
12:41 PM IchGucksLive: imoff watering garden
12:41 PM pcw_home: Yow! sounds like a really bad dental appointment
12:50 PM Tecan: https://github.com/tecan/PCF8574-SWire-Arduino.git so you can use any digital pins for i2c and pcf8574
01:02 PM gloops: 4 flute 18000rpm?
01:19 PM Simonious: anyone happen to know if pulling gerber files into solidworks is a thing you can do?
01:38 PM Simonious: next question.. anyone ever done this: http://tinylabs.io/openfixture-kicad-export/
01:39 PM sync: yeah djdelorie I might have to do that
01:39 PM sync: I need to get the board edge connectors tho
01:40 PM sync: although I have not fully understood how to actually open the thing
01:42 PM djdelorie: sync: I have to wonder, though... WHY?
02:14 PM gloops: im struggling to think of how the economy will work when machines do most jobs
02:14 PM CaptHindsight: the machines will be just fine, same as their owners
02:15 PM gloops: the owner class will surely become obsolete
02:15 PM Simonious: I recommend people actively steel and dissemimate this technology at every step of the way..
02:15 PM CaptHindsight: meat machines will become obsolete
02:15 PM Simonious: *steal
02:15 PM gloops: profit will be something of the past
02:15 PM roycroft: machines will never do most jobs
02:16 PM roycroft: they will do the jobs that they're good at doing
02:16 PM methods_: that's what horses said
02:16 PM gloops: theyre good at everything
02:16 PM gloops: what im saying is, you need someone with an income to buy your products
02:16 PM roycroft: you'd go to a strip club to watch a machine undress?
02:16 PM gloops: if there are no employed workers - nobody can buy the things the machine makes
02:17 PM Simonious: roycroft: don't judge me
02:17 PM methods_: right
02:17 PM * methods_ hides fleshlight
02:17 PM roycroft: s/you/most folks/
02:17 PM roycroft: it's not a judgement thing
02:17 PM gloops: roycroft people watch simulated porn - and now robot sex dolls
02:17 PM gregcnc: make things people with money want
02:17 PM roycroft: i really don't care what turns your crank
02:17 PM CaptHindsight: meat machines will be used for dangerous jobs like porn
02:17 PM Simonious: roycroft: the short answer is yes, people will pay to watch machines undress.
02:17 PM gloops: gregcnc machine owners buying stuff other machine owners machines made?
02:17 PM gloops: theyd just it make it themselves
02:17 PM gregcnc: yes
02:18 PM gregcnc: bascially how it is now
02:18 PM gregcnc: are you building you own car, coffee maker, house, etc now?
02:18 PM gloops: almost 8 billion human beings will be just surplus organisms
02:18 PM CaptHindsight: rulers and peasants don't need todays economies
02:19 PM roycroft: but if it gets to the point where machines really do all the work, we'll basically be in a star trek universe, where money is obsolete and people will not want for anything
02:19 PM roycroft: that's not going to happen any time soon
02:19 PM roycroft: so i'm going to keep making parts
02:19 PM gloops: roycroft so i just message the factory and get what i want? for nothing?
02:19 PM CaptHindsight: they didn't 500 years ago
02:19 PM gloops: there will be no taxes - no government
02:20 PM CaptHindsight: oh you'll just eat your gruel and be quiet
02:20 PM gloops: gregcnc no but im not exactly an 'owner'
02:20 PM gregcnc: work for someone who is
02:20 PM gloops: 'owners' wear top hats and have running boards on their cars
02:20 PM gregcnc: or become an owner
02:21 PM gloops: nah not for me
02:21 PM gloops: its the beginning of then end
02:21 PM gregcnc: if you think that way it will never happen
02:21 PM gregcnc: plenty of people start with toy machines and turn it into real business
02:21 PM gloops: accountants, auditors, boards etc
02:21 PM CaptHindsight: nah wear things like this http://www.halloweenplayground.com/images/legavenue/royal-king-costume.jpg
02:21 PM gloops: i like it as i am - nothing at all really
02:22 PM gregcnc: then what are you complaining about?
02:22 PM gloops: im not complaining, im just trying to get some idea of what the world will be like
02:22 PM CaptHindsight: he's hot is all, let him complain
02:22 PM gregcnc: if you don't mind others amking the world go round, why start worrying about it now?
02:23 PM gloops: its the economics of it i cant grasp
02:23 PM CaptHindsight: watch all the Twilight Zone episodes on the future
02:23 PM gloops: nobody is going to be earning
02:23 PM gloops: we now have driverless buses in the UK
02:23 PM gloops: and HGVs
02:24 PM CaptHindsight: the US has a glut of driverless horses
02:24 PM gregcnc: vote with your money
02:24 PM Tecan: https://github.com/tecan/Adafruit_SSD1306-SWire-Arduino a nice small display, also can be used with any 2 digital pins for i2c.
02:24 PM gregcnc: we have driverless cars too, never mind the warm body in the drivers seat
02:24 PM gloops: machines are doing brain operationd
02:24 PM gloops: operations
02:25 PM gregcnc: problem solved you won't know the difference after they operate on you
02:25 PM gloops: i fear something terrible will happen
02:25 PM roycroft: i have not seen archivist for a while - does he still frequent this channel?
02:25 PM CaptHindsight: think about how dofferent things would be if everyone got a chance to run a country, say 15 minutes each
02:26 PM * roycroft would not want to run a country for even 15 seconds
02:26 PM CaptHindsight: and you don't get to choose the next country
02:26 PM roycroft: except maybe uzbekibekistan :)
02:26 PM gregcnc: like developing countries will be the only life left after civilazed people can't survive without infrastructure?
02:26 PM CaptHindsight: uzbeks
02:26 PM CaptHindsight: watch your liquor
02:27 PM FinboySlick: Glory to Arstozka!
02:27 PM gloops: archivist has signed off for good
02:27 PM FinboySlick: (nobody will get the reference)
02:27 PM CaptHindsight: don't blame him, it's gotten rather silly in here
02:27 PM gregcnc: somebody pissed him off
02:28 PM gloops: all the serious machinists have gone
02:28 PM gregcnc: they are out making the world go round
02:28 PM gloops: gregcnc you cant blame the germans for everything
02:28 PM FinboySlick: No no, it's flat. I saw an article on facebook about that.
02:29 PM FinboySlick: Most of the crust is granite. We use granite as flat references. Coincidence... I think not!
02:30 PM CaptHindsight: good catch
02:30 PM gregcnc: somebody linked their twitter here, i had a headache after looking at that
02:30 PM XXCoder: lol machinist version of flat world
02:30 PM XXCoder: "earth is rated for AA flatness!"
02:30 PM gloops: Glory to Artstozka is a phrase used by fans of the game 'Papers, Please', in which you honour the nation communist nation Artsozka.
02:30 PM FinboySlick: Claciers are God's Biax scraper.
02:30 PM XXCoder: just... lot of dirt on it :P
02:31 PM CaptHindsight: well if people were flat they would take up less space and be easier to stack
02:32 PM gloops: talking of which i picked up a lovely vintage scraper at the car boot sale, it doesnt scrape though
02:32 PM gloops: not sure how to sharpen it
02:32 PM FinboySlick: Just shy of 90° on either side if I recall.
02:33 PM gregcnc: gloops this is all you need https://www.instagram.com/p/BgTG2qPjfZ6/
02:33 PM FinboySlick: The straighter the edge, the closer you are to a finish scraper.
02:33 PM gloops: http://2.bp.blogspot.com/-Ur5JNz9LHyM/TboJQsd2cwI/AAAAAAAAAE8/6SmhLpPjKcI/s1600/SDC10978.JPG
02:33 PM roycroft: when i was at the country fair this year some old geezer came up to our booth and exclaimed "those flat earthers are nuts. there's no way the earth is flat! just look at that mountain over there!"
02:33 PM roycroft: then he walked away
02:33 PM gloops: like that
02:33 PM CaptHindsight: cars here don't have boots, only shoes
02:33 PM roycroft: cars in the uk have boots
02:33 PM roycroft: that's where you store your extra shoes
02:34 PM gloops: whats the technique with those curved sole scrapers?
02:34 PM CaptHindsight: I ws wrong CV's have boots
02:34 PM FinboySlick: gloops: Oh, not sure about those.
02:34 PM gloops: it doesnt cut at all going forward, it does scrape a bit with sideways riving king of motion
02:35 PM gloops: kind
02:35 PM roycroft: the technique is to regrind it so it scrapes when you push it :)
02:35 PM CaptHindsight: gregcnc: seems nobody got that twitter is for twits
02:36 PM gregcnc: I assumed there was a yt link but couldn't find one
02:36 PM gloops: ill stone it up, tbh i think they were hardened, there seems to be a soft area on it
02:37 PM gloops: probably for white metal or something
02:38 PM gloops: gregcnc who are you going to sell a solid sofa to?
02:39 PM gregcnc: anyone with money
02:39 PM gloops: not someone on the third storey
02:39 PM FinboySlick: It looks cool but I think it would lose a lot of points for comfort.
02:40 PM gloops: at least you cant lose stuff down the side though
02:40 PM gregcnc: http://www.bgisupplies.co.uk/
02:40 PM FinboySlick: Especially once the carpenter ants start coming out.
02:41 PM gloops: there is a market for these fabulous decor things, but you wouldnt want to deal with the people who buy that stuff
02:42 PM gregcnc: for money, you would
02:42 PM gloops: i wouldnt - i have as an employee when i was young, i wouldnt now
02:43 PM gloops: you go to hang a door or something and the stupid wife is there 'oh where are your dust sheets, i want total coverage'
02:44 PM gregcnc: and you chareg accordingly
02:45 PM gloops: too stressful
02:51 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Inline_spacer.jpg
02:51 PM Tom_L: should have been a lathe part but it wasn't
02:51 PM gregcnc: chatter on ID?
02:51 PM Tom_L: a little but it's not a big deal on this
02:52 PM gloops: missed that - https://www.facebook.com/marketplace/item/284744588772735
02:52 PM gregcnc: correcting feedrate for hole radius should fix that
02:52 PM Tom_L: and i could have done better on the lead in/out but it's all good
02:53 PM gregcnc: looks pretty small
02:53 PM Tom_L: probably 6mm hole
02:53 PM Tom_L: i forget
02:53 PM Tom_L: all with a 1/8" em
02:54 PM Tom_L: easier to make 'a few' on the mill than the manual lathe
02:55 PM Tom_L: that's before any debur
02:55 PM Tom_L: i wish i had a tumbler
02:56 PM gregcnc: for three parts?
02:56 PM Tom_L: no i did em 3 at a time
02:56 PM gregcnc: oh
02:56 PM Tom_L: gonna make a few more
02:56 PM Tom_L: i programmed 4 up but the scrap material was only wide enough for 3
02:57 PM gregcnc: toolchange and chamfer mill?
02:58 PM gloops: what bit, speed, feed etc Tom_L ? i ve got a lump of ally set up to work on tommorrow, the standard speed and feed calculators dont seem to be having the desired outcome for me
02:58 PM gloops: reluctant to drop air cooled spindle lower than 6000rpm, but will have to
02:59 PM Tom_L: i ran mine at 4k because it likes it there and about a .001" chipload
02:59 PM gregcnc: what kind of problems are you seeing with normal cutting parameters?
03:01 PM gloops: hmm ill have to look again, i think im working on .1mm chipload
03:01 PM gloops: gregcnc chattering mainly
03:02 PM gloops: slow the feed its ok, but slow

03:03 PM Tom_L: P1 fits in the slot, P2 fits in the cutouts. 1 program with an op stop
03:04 PM gloops: i am hoping to make some dies, which it would do, but the calculator rates dont work - im not getting lovely chips, ill practice some more anyway nit used ally much
03:05 PM Tom_L: the chatter on mine is the small cutter cutting pretty much it's full cut length
03:05 PM Tom_L: the outside is ok other than the dimples which i should fix but probably won't on this
03:06 PM Tom_L: i could have used a drill/reamer too
03:07 PM Tom_L: it's pushing the limits with the vise to use drills
03:07 PM gloops: ive only used 3mm bit, ill try a 6mm
03:07 PM Tom_L: at some point in time i may make a taller Z
03:07 PM Tom_L: rule of thumb, use the biggest cutter that will fit
03:07 PM Tom_L: and keep it as short as possible
03:07 PM gregcnc: .1mm for 3mm tool is a lot
03:08 PM Tom_L: yeah probably so
03:08 PM gloops: well, you see videos of them hogging ally out like lightning
03:08 PM gloops: im barely taking a shave off
03:09 PM gregcnc: obviously many things come into play, but what you get on your machine is what you have to deal with
03:09 PM gregcnc: and find paramters that work
03:09 PM gloops: yes, it needs some experimenting, i need some bigger single flute cutters
03:10 PM Tom_L: i'm stoked about the micrometer i got free https://www.mscdirect.com/product/details/04081394
03:11 PM Tom_L: my kid won it at his competetion but he already has one
03:12 PM XXCoder: dang
03:12 PM XXCoder: same one as I have, but got for free dang!
03:12 PM XXCoder: its good one, though I use starret small one a lot more. mine was made in 1950s lol
03:12 PM XXCoder: wood box is awesome
03:13 PM Tom_L: i've got an old set up to 2" i keep in the shop
03:13 PM Tom_L: this will probably stay in my office
03:13 PM XXCoder: framed? ;)
03:13 PM Tom_L: no, i'm using it
03:14 PM Tom_L: gets too warm in the shop to keep it's accuracy right
03:15 PM XXCoder: I keep my tools permently near area where I work at. that way theres no temperate changes as I use it
03:15 PM XXCoder: summer is the worse
03:15 PM XXCoder: shop loses around 10 to 20 f from start of shift to 1:45 am
04:06 PM Deejay: gn8
04:35 PM Tom_L: gloops, i'm still experimenting with mine to find what it likes
04:37 PM gloops: Tom_L yeah i need to get some hours in with aluminium, had a couple of months off
04:37 PM Tom_L: i can take a full width 1/8" cut same depth ok but i generally go a bit more shallow
04:38 PM Tom_L: i can take a 1/4" full width cut same depth ok but the spindle gets too hot
04:38 PM gloops: 1/8th deep?
04:38 PM Tom_L: 1/4
04:39 PM gloops: i cant seem me doing that lol
04:39 PM gloops: see
04:41 PM Tom_L: https://www.youtube.com/watch?v=VUDHCXu4Pwo
04:41 PM Tom_L: volume warning
04:41 PM Tom_L: that's the 1/4" cutter
04:41 PM Tom_L: but not full width
04:44 PM Tom_L: ~4:30 is full width
04:53 PM gloops: id be happy with 1mm depth, even .5
04:54 PM gloops: ill get a video anyway when i do run it on ally again, hopefully tommorrow
05:00 PM Bob is now known as Guest50231
05:02 PM Guest50231: First time to drop in...converting an old Dyna 2200 mill to run on Linux cnc
05:03 PM Guest50231: Checking out
05:03 PM gloops: having any problems?
06:32 PM roycroft: it just hit 40 degrees at my house
06:32 PM roycroft: no wonder i'm so miserable
06:33 PM sync: 40°F? that is quite cold
06:35 PM roycroft: i don't know what that 'f' stuff is :)
06:35 PM roycroft: 40 real degrees
06:36 PM sync: you mean 564°R?
06:37 PM hazzy-lab: sync: LOL
06:37 PM roycroft: it's funny
06:38 PM roycroft: "fahrenheit", for such a tinny unit, has a very woody sound
06:38 PM roycroft: i'd say that "celcius" sounds more tinny than "fahrenheit"
06:39 PM hazzy-lab: but "centigrade" sounds bigger than "fahrenheit"
06:40 PM roycroft: "centigrade" also sounds a lot more woody than "celcius"
06:40 PM roycroft: but still not as woody as "fahrenheit"
06:41 PM gregcnc: you can hear temperature over there?
07:07 PM CaptHindsight: 302 K currently
07:11 PM roycroft: that is almost cool
07:12 PM CaptHindsight: yeah we got a cool spell last week and this week
07:13 PM roycroft: i am going over to the maker space in an hour to get oriented on the bridgeport
07:13 PM roycroft: there is little ventilation there, and no a/c
07:13 PM CaptHindsight: 50's F at night
07:13 PM roycroft: i'm not looking forward to that aspect of it
07:14 PM CaptHindsight: https://images-na.ssl-images-amazon.com/images/I/61y4XwY401L._SX425_.jpg
07:15 PM roycroft: it's been so hot i had to pitch my tent in the back yard and have been sleeping in it for the past couple nights
07:15 PM roycroft: i have to do that every year when we have our prolonged heat wave
07:16 PM roycroft: my bedroom gets too hot to sleep in, even with a big fan and the window open
07:17 PM SpeedEvil: I keep meaning to make a personal cooler, but the climate doesn't justify it.
07:18 PM SpeedEvil: http://www.veskimo.com/liquid-cooled-microclimate-vest.html = two t-shirts,50m of silicone fish airline, assorted fixtures, small peristaltic pump, and a thermos with ice-cubes in.
07:19 PM SpeedEvil: Total $50 or so.
07:19 PM roycroft: we only get this kind of heat wave for a couple or three weeks out of the year
07:19 PM CaptHindsight: an indoor pool is another idea
07:21 PM CaptHindsight: https://media.spokesman.com/photos/2015/08/07/moose_pool_bull_lying_t1140.jpg?abf36d44fcda22a1f7041162086f31df6a374511
07:21 PM roycroft: i always go camping on the coast for a week in august
07:22 PM roycroft: that takes care of one week of the heat

07:54 PM Frank_10: hi guys
07:55 PM Frank_10: little question if anyone minds to chime in, have you ever seen a dual stage belt reduction? im having a servo with 3000rpm max with rack and pinion
07:55 PM Frank_10: i need aprox 10:1 reduction
07:56 PM Frank_10: without spending 1000 bucks on planetary, are belts posible?
07:56 PM Frank_10: cant seem to find much on google
07:56 PM R2E4: Allo all....
07:57 PM hazzy-lab: Frank_10: I don't see why not
07:57 PM SpeedEvil: Frank_10: no particular reason.
07:57 PM SpeedEvil: It may not be the most efficient.
07:57 PM SpeedEvil: Also - dual - 10:1 may be in the range of one.
07:57 PM R2E4: 7i76 and big stepper, with 10:1 planetary gear I can only get 360 before it start throwing following errors. Is there something I can change in the PID?
07:58 PM R2E4: I dont really understand the PID and stepper thing......
07:59 PM R2E4: I can get 550 easy without any errors on the Y which is a 900oz/in stepper. The X is a600 oz/in stepper
07:59 PM hazzy-lab: R2E4: Following errors with a stepper?? I think you have some other problem that is causing the following error
07:59 PM hazzy-lab: or do you have encoders with the steppers?
08:00 PM Frank_10: speedevil: what do you mean by not beeing in the range of one? i mean, what do you mean with one? one grand?
08:00 PM Frank_10: sorry
08:00 PM SpeedEvil: I mean one gear
08:00 PM SpeedEvil: 10:1 pulley diameter ratio
08:00 PM R2E4: no encoders on the steppers
08:01 PM Frank_10: it would be something like a 400mm diameter pulley
08:01 PM Frank_10: kind of weird if you ask me
08:01 PM Frank_10: 14 teeth has the pulley on the motor
08:01 PM R2E4: What is the following error from? Using pnconf config
08:01 PM SpeedEvil: depends on the small diameter, and pitch.
08:01 PM SpeedEvil: I know my lawnmower does about that.
08:02 PM R2E4: It is planetary gearbox
08:03 PM R2E4: sorry guys, I saw 10:1 and thought you were responding to my situation. Then I read up....
08:06 PM hazzy-lab: R2E4: LCNC knows nothing about whether the stepper is able to keep up or not, so I don't think the hardware is the problem
08:07 PM hazzy-lab: I think the only way you can get f-errors in stepgen-based systems is a base thread period which is too long for the requested step frequency
08:07 PM yosi: holis
08:08 PM hazzy-lab: So it you are microstepping you would try lowing the number or microsteppers
08:08 PM hazzy-lab: microsteps*
08:08 PM hazzy-lab: gosh, was that english?
08:09 PM yosi: What is your name
08:09 PM R2E4: I removed microsteps, or at the lowest with these drives
08:10 PM yosi: Hello
08:10 PM R2E4: change steplen or stepspaceing?
08:11 PM hazzy-lab: R2E4: Yes, i think that is the next thing to try
08:11 PM hazzy-lab: yosi: Hello!
08:11 PM yosi: hello
08:11 PM yosi: change steplen or stepspaceing?
08:12 PM R2E4: I gues it would depend on the drive specs
08:12 PM yosi: :-[
08:12 PM hazzy-lab: yosi: Sorry, when I said "gosh, was that english?" I was refering to what I wrote!
08:12 PM R2E4: Hi yosi
08:12 PM yosi: soy yo
08:13 PM yosi: you are talking about me
08:13 PM hazzy-lab: no
08:14 PM yosi: what but that's my name
08:15 PM yosi: that is my other name
08:15 PM yosi: what are you guys up to
08:17 PM R2E4: Need to check the driver manual to see what it is expecting otherwise I am just guessing, and I am not very lucky.
08:18 PM hazzy-lab: R2E4: Does it work if you jog at low speeds?
08:18 PM yosi: WHAT ARE YOU DOING
08:20 PM R2E4: yes it works fine at 360 ipm, anything above 375 it spits an error at me
08:21 PM yosi: LOCOOOOOOOOOOOOOOOOOOOO

08:23 PM R2E4: hazzy-dev: yeah it did nothing. change base thread?
08:23 PM hazzy-lab: Yes that should help, but you can only change that so much

08:31 PM R2E4: my y is send more than twice the pulses and it can go to 500ipm
08:31 PM R2E4: so how can it be the base thread?
08:32 PM hazzy-lab: R2E4: that is interesting, that means it it probably not the base thread
08:32 PM hazzy-lab: oh no
08:36 PM yosi: ;-)
08:37 PM R2E4: https://imagebin.ca/v/49qgd0hjy9T5\
08:37 PM R2E4: thats what the drive expects
08:37 PM R2E4: its all set to 1000, but doesnt explain why the Y is ok
08:37 PM hazzy-lab: R2E4: that's a 404
08:38 PM yosi: HOLOIS
08:38 PM yosi: :-[
08:38 PM yosi: QUE HACEN
08:38 PM R2E4: https://imagebin.ca/v/49qgd0hjy9T5
08:38 PM hazzy-lab: R2E4: That is very strange. The the Z and Y axes have the same set up?
08:39 PM hazzy-lab: thanks, that link it goo
08:39 PM hazzy-lab: d
08:39 PM hazzy-lab: those look like pretty standard timings
08:40 PM R2E4: no, I scale for the Y is at 2400 and microstepping and 3:1 pully and it is 525 oz/in, the X is 1600 os/in stepper 10:1 planetary gearbox with no microstepping and scale set to 900
08:41 PM R2E4: in the ini from pnconf all are at 1000
08:41 PM R2E4: steplen space etc...
08:48 PM R2E4: I got it....
08:50 PM hazzy-lab: Hurray!
08:50 PM hazzy-lab: What was it?
08:57 PM R2E4: Up to 800IPM
08:57 PM hazzy-lab: Sweet!
08:58 PM R2E4: STEPGEN_MAXVEL and STEPGEN_MAXACCEL
08:58 PM R2E4: I am sure I can go more, it is smooth.....
08:58 PM hazzy-lab: Oh, yep, that would do it
08:58 PM hazzy-lab: I should have though of that, they have to be 25% greater
08:58 PM R2E4: I set it what it said to set it at, but it was too low
09:09 PM R2E4: up to 1000 IPM no problem on the X the Y stalls at 800
09:10 PM hazzy-lab: excellent, so now X is better than Y!
09:17 PM R2E4: yeah. I was following what they have as comments in the ini for the settings and I was driving the axis up to the max set there hence the error. Once I gave it headroom, it was free up to max velocity.
09:17 PM R2E4: The Y is limited but I am microstepping alot with the Y so if I cut that I would probably get more but the Y is only 48" so it would not have time to ride at full speed anyway.
10:52 PM roycroft: i just joined up at the eugene maker space so i can use that bridgeport cnc mill
10:52 PM roycroft: it's a pretty funky machine, but i think i'll find it useful
10:56 PM Tom_L: does it work?
10:56 PM Tom_L: did they have the manual for the interface?
10:56 PM roycroft: mostly
10:56 PM roycroft: yes, i have the manual
10:56 PM Tom_L: what series is it?
10:57 PM Tom_L: boss5..9?
10:57 PM roycroft: it has pneumatic spindle control which they disconnected, because they did not want to turn on the compressor sitting next to the machine
10:58 PM roycroft: dx32
10:58 PM roycroft: anyway, they installed a vfd and do speed control with that
10:58 PM roycroft: but the cnc controller barfs because of low air pressure
10:59 PM roycroft: so on has to escape to clear the alarm
10:59 PM roycroft: then trying to run a program it complains about the spindle speed
10:59 PM roycroft: so one has to read the speed that it thinks it's running at
10:59 PM roycroft: stop the program
10:59 PM roycroft: edit the gcode and add an s command that matches the speed that it thinks it's running at
11:00 PM roycroft: and then the code will run
11:00 PM roycroft: but it makes parts
11:00 PM roycroft: it also has a funky spindle
11:00 PM Tom_L: slow but steady
11:00 PM roycroft: kwik something
11:00 PM roycroft: it's kind of like a cat taper
11:01 PM roycroft: which means i can't bring much of my tooling
11:01 PM roycroft: because my mill is r8
11:01 PM Tom_L: yeah we would preset the tool holders and line them up on the bench in order
11:01 PM roycroft: that's what i suggested
11:01 PM roycroft: the guy demoing it said he just tries to use one tool for the whole job
11:01 PM Tom_L: nonsense
11:01 PM roycroft: i asked if he had a jig to measure tool length offsets
11:02 PM roycroft: and he didn't know what i was talking about
11:02 PM roycroft: this was the guy who owns the mill and uses it the most
11:02 PM roycroft: anyway, i have access to a mill with a relatively long table now
11:02 PM roycroft: and that can do a lot of the work automagically
11:03 PM roycroft: their membership is $25/month
11:03 PM roycroft: and i have 24/7 access to the shop
11:03 PM roycroft: so that's not a bad deal
11:04 PM roycroft: most of their equipment doesn't work at all
11:04 PM roycroft: but everyone there is scared of the "big milling machine"
11:04 PM roycroft: so nobody uses it
11:05 PM nallar is now known as Ross
11:05 PM Tom_L: i can't remember now what we used to preset the tools but we did
11:06 PM roycroft: just a holder and a height guage is all that's needed
11:06 PM Tom_L: they won't all be the same though
11:07 PM Tom_L: i forget how we entered the tool offsets
11:07 PM roycroft: the toolholders vary a lot?
11:07 PM Tom_L: the tools do
11:07 PM roycroft: yeah
11:08 PM roycroft: but the tool holders index to the spindle consistently, don't they?
11:09 PM Tom_L: they should
11:09 PM roycroft: so if you stick a tool in a toolholder and put it on your little stand you can index off that tool
11:10 PM roycroft: stick another tool/toolholder in the stand and the offset of that tool from the first one should be the same offset on the mill, shouldn't it?
11:10 PM hazzy-lab: roycroft: Those kwik BP spindles can be worth quite a bit!
11:10 PM roycroft: that's what the guy told me
11:10 PM hazzy-lab: You can get R8 adapters for them
11:10 PM roycroft: i mused about possibly buying some so that i could pre-index my own tooling
11:11 PM roycroft: and the guy told me that they're getting really scarce
11:11 PM hazzy-lab: They are, especially the tool holders
11:12 PM roycroft: oh, they're not that bad
11:12 PM roycroft: https://www.ebay.com/itm/302805356880
11:12 PM hazzy-lab: There is an auto shop near me that has a real nice complete set of tooling, including auto boring heads, face mills etc.
11:12 PM roycroft: now a more common size might be pricey
11:13 PM sync: djdelorie: because I have equipment using it
11:13 PM Tom_L: i don't remember the boss5's looking like that
11:13 PM roycroft: https://www.ebay.com/itm/183040349153
11:14 PM roycroft: that's definitely what this mill uses
11:14 PM hazzy-lab: Thats not bad at all
11:14 PM roycroft: i was expecting $50+ each from what the guy was saying
11:14 PM Tom_L: do those use retention knobs?
11:15 PM hazzy-lab: I know some of them are very expensive, probably thinks like face mills and chucks
11:15 PM roycroft: there's a collar on the end of the spindle that rotates about 1/4 turn to lock them in place
11:15 PM roycroft: you insert the holder until the tabs seat than turn the collar
11:16 PM roycroft: i have a nice 2" carbide face mill that i was planning on using with this machine
11:16 PM roycroft: but that's not going to happen
11:16 PM roycroft: and they don't have any face mills or even fly cutters
11:16 PM roycroft: i'll have to use little end mills for facing
11:18 PM Tom_L: i can stretch my fly cutter out to about 2.5" but that's pushing it
11:18 PM CaptHindsight: roycroft: do the makerspace members there believe in bathing?
11:18 PM roycroft: for the most part, yes
11:18 PM roycroft: however, it was 40 degrees here today
11:19 PM CaptHindsight: the one in Chicago had serious problems with hygiene
11:19 PM roycroft: so even well-showered folks were a bit ripe
11:19 PM roycroft: but
11:19 PM roycroft: as i said a while ago
11:19 PM roycroft: i have 24/7 access to the maker space
11:19 PM roycroft: so if hygiene becomes an issue i can just show up when obody is there
11:19 PM roycroft: nobody
11:19 PM roycroft: like during the day, when they're all sleeping :)
11:20 PM CaptHindsight: in the middle of winter the odors were of fermented bathroom and pickles
11:20 PM Tom_L: do you get lockers or something to keep your junk in?
11:20 PM roycroft: no, there are tables and cubbyholes
11:20 PM roycroft: i will never leave anything there
11:20 PM roycroft: not parts, not materials, not tooling
11:20 PM CaptHindsight: yeah late night and early morinings were safer
11:21 PM roycroft: i'll pack it all in and pack it all out every time
11:22 PM roycroft: they don't even have way oil or coolant
11:22 PM roycroft: so i'll pack that in and out as well
11:22 PM Tom_L: my kids are getting more interested in my mill since i've been making a few parts for them
11:23 PM roycroft: i did have my first "encounter" with the geeks there tonight
11:24 PM roycroft: they were going on and on about how great open source software is
11:24 PM roycroft: and then trying to convince me to use fusion 360
11:24 PM roycroft: i just politely told them that i have my own software tools that i'm familiar with and would not want to tie up their computers for doing design work that i can do at home quite easily
11:25 PM roycroft: one of them kept pushing about fusion 360
11:25 PM roycroft: so i mentioned that i'll be making prototypes for possible commercial products, and was unwilling to pay for a license for fusion 360, especially since i have my own tools already
11:26 PM roycroft: and he told me that i can just ignore the licence terms, and that autodesk are never going to go after a small user
11:26 PM roycroft: i let him know in no uncertain terms that that was crossing a line
11:26 PM roycroft: that i would not judge him for what he does
11:27 PM roycroft: but trying to coerce someone into violating a software license is inappropriate
11:27 PM roycroft: he was very taken aback
11:27 PM djdelorie: even open source advocates encourage honoring licenses
11:27 PM roycroft: yes
11:27 PM roycroft: mostly by not using the software :)
11:28 PM djdelorie: open source software itself has a license, of course :-)
11:28 PM roycroft: sadly, i wasn't surprised that this came up
11:28 PM roycroft: i'm actually pretty happy it came up so soon
11:28 PM roycroft: because the others who are there know where i stand on the issue
11:28 PM roycroft: it's the same thing on this channel
11:29 PM roycroft: i am sure that a significant number of people who hang out here use pirated software on a daily basis
11:29 PM roycroft: but we don't discuss that
11:29 PM roycroft: that's how it should be at a maker space
11:37 PM roycroft: kwik switch tapers are 3.5"/foot - exactly the same as cat tapers
11:37 PM roycroft: i thought it looked like a little cat taper
11:39 PM sync: djdelorie: it is a form talysurf
11:39 PM sync: a combined shape/roughness measurement device
11:39 PM djdelorie: sync: is it one of the dumb terminals, or a pc clone?
11:41 PM sync: the terminal is a dumb one
11:41 PM sync: but the dg10 is something with dual 5.25" floppies and I think an 80186
11:42 PM roycroft: the bridgeport mill i'm dealing with originally came with an ibm at computer
11:42 PM roycroft: but it's been "upgraded" to a 486
11:48 PM sync: I found the schematics of the terminal
11:48 PM sync: at least it is some kind of x86
11:48 PM sync: so I can just shove the software through IDA
11:49 PM djdelorie: nothing DG made was truly "standard"
11:50 PM djdelorie: marvels of engineering, yes; marvels of compatibility or market sense... no.
11:52 PM sync: well, I guess trying to reverse the OS is going to give me cancer, but the highlevel application should reverse acceptably well
11:54 PM sync: I'm rather impressed with the hardware tho
11:54 PM djdelorie: also, half the bits are numbered backwards because of a lawsuit...
11:54 PM sync: all the plastic is really heavy and still soft after 30+ years
11:54 PM djdelorie: yeah, those were the days of peripherals that doubled as seige weapons.
11:55 PM sync: oh god
11:55 PM djdelorie: we once had a line printer that could cut your fingers off
11:55 PM sync: did they also invent their own storage format on the discs?
11:55 PM sync: because then this will be a pain
11:55 PM MrHindsight: https://imgur.com/gallery/Wzg81Av Hammer drill
11:56 PM djdelorie: you mean the sector layout, or the fat filesystem?
11:57 PM djdelorie: anything running a dos clone should be FAT16 but there's a couple different options for the physical sector layout on disk
11:58 PM sync: well, the magnetic layout, yes
11:58 PM sync: or even the modulation scheme
11:58 PM sync: huh
11:58 PM sync: that thing was made everywhere
11:59 PM sync: the back says singapore, the floppy drives are japanese, the cabling is made in thailand
11:59 PM sync: wat
11:59 PM djdelorie: iirc if it uses the standard-of-the-day drives, you should be able to read the old format on a new drive. The other way doesn't work though
