12:40 AM miss0r: mornin
12:55 AM hazzy-lab: miss0r: Night!
12:55 AM hazzy-lab: :D
12:55 AM miss0r: Depends on where you live :
12:56 AM hazzy-lab: Well, I guess it IS technically morning here too
12:56 AM miss0r: hehe. Didn't catch much sleep?
12:58 AM hazzy-lab: Getting ready to try, but having too much fun thinking about various projects hehe
01:03 AM miss0r: hazzy-lab: I know the feeling. I managed to get my EDM spindle mounted to the new linear axis yesterday. I will pick up on that again today. I need to build a new controller for it
01:04 AM IchGucksLive: morning from germany
01:04 AM hazzy-lab: Nice! Some day I'd like to build an EDM ...
01:04 AM IchGucksLive: getting a thunder day here clouds plum
01:04 AM hazzy-lab: Motoring Ichs
01:04 AM hazzy-lab: Morning*
01:05 AM hazzy-lab: You can tell it is late here :D
01:05 AM miss0r: hazzy-lab: https://imgur.com/a/PxCUTvv
01:05 AM miss0r: morning IchGucksLive
01:07 AM IchGucksLive: i need to take action in garden for the upcoming rain
01:07 AM hazzy-lab: miss0r: That looks good! Probably showing my ignorance. but is it actually a spinning spindle? How would that be used on an EDM?
01:07 AM IchGucksLive: im off to be continioud
01:09 AM miss0r: hazzy-lab: I know it looks a bit like those chinesium ones. But that 'spindle' part is actualy a 20 rpm spindle, with through tool water flow, powertransfer & completely isolated from the chassis.
01:09 AM hazzy-lab: AHA, that makes sense, so it just spins the wire for even wear?
01:10 AM miss0r: The reason I want this is because when making holes with the brass tubes I use, I end up getting a very uneven wear on the end of the tube. This generates a much larger surface area, which in turn requires alot more power for the sparking, making it harder to regulate
01:10 AM miss0r: yeah
01:10 AM miss0r: It ended up being a damn complicated spindle build that one :]
01:11 AM hazzy-lab: Interesting, so this is not wire EDM, more like die sinking? All I know about is wire EDM
01:12 AM miss0r: this is not even a die sinking... its referred to as a hole shooter.
01:12 AM miss0r: (directly translated from danish)
01:12 AM miss0r: i.e. broken tap remover :]
01:12 AM miss0r: It 'could' be used for die sinking, I guess
01:13 AM miss0r: https://imgur.com/a/Onitj88 heres a bunch of photos of the spindle being put together
01:20 AM hazzy-lab: miss0r: Very nice work! I like the way you did the four carbon brushes
01:20 AM hazzy-lab: Ok, better try and sleep
01:21 AM hazzy-lab: gn8
01:23 AM miss0r: goodnight
02:35 AM Deejay: moin
04:36 AM orr_: hello/ is it possible to install linuxcnc on debian9? not for real work. for debugging gcode. sim is enough.
04:59 AM XXCoder: orr_: should be, but then maybe its just too different.
05:00 AM orr_: trying to compile from git, but it has a hell lot of dependencies.
05:01 AM XXCoder: mine was much simpler. I just added repos and installed it
05:01 AM XXCoder: xfce mint
05:04 AM orr_: which repo?
05:04 AM XXCoder: umm it got wiped with upgrade so not too sure
05:05 AM XXCoder: http://linuxcnc.org/docs/html/getting-started/getting-linuxcnc.html
05:06 AM XXCoder: ubuntu type only. debian I dont know if will work
05:06 AM XXCoder: h theres debian weheezy also
05:06 AM XXCoder: *ah
05:07 AM XXCoder: if just testing you dont need to do rt part
05:12 AM orr_: oh sh
05:13 AM orr_: https://pastebin.com/fpAMQSNR
05:13 AM XXCoder: interesting
05:15 AM orr_: i think i also would try mint. debian went crazy
05:16 AM XXCoder: is it pc for linuxcnc only?
05:16 AM orr_: yes
05:17 AM orr_: virtual machine actually
05:17 AM XXCoder: yeah as well as make dvd or usb drive and install
05:17 AM XXCoder: faster
05:18 AM XXCoder: virtual is even easier, mount iso in it, then install
05:18 AM XXCoder: "insert" iso as cdrom or something
05:54 AM orr_: oh, yes, i made it
05:54 AM XXCoder: way to go
05:57 AM Tom_L: orr, https://paste.ubuntu.com/p/jvDN76Pq7Z/
05:58 AM Tom_L: http://www.linuxcnc.org/testing-stretch-rtpreempt/
05:59 AM orr_: deb http://linuxcnc.org/ stretch base 2.7-uspace - this is what i was looking for. thanks!
05:59 AM orr_: Tom_L, http://www.linuxcnc.org/testing-stretch-rtpreempt/ - can it be used for machinery?
06:00 AM orr_: wheezy is too old
06:00 AM Tom_L: why do you say that?
06:00 AM Tom_L: i'm using wheezy on my mill
06:01 AM orr_: i also do. but i cannot update chrome or firefox to modern state
06:01 AM orr_: wheezy is too old not for machine, but for 2018
06:01 AM orr_: for common usage
06:02 AM Tom_L: do you need preempt or RTAI?
06:02 AM Tom_L: those _TEST_ images are for preempt-rt
06:03 AM orr_: for testing -nope. for machine - yes. i am building another machine. and wonder if i could use any modern distro
06:04 AM orr_: ah
06:42 AM jthornton: morning
08:37 AM hazzy-lab: morning
09:10 AM jesseg: Good Morning
09:32 AM Vq: Good afternoon
10:11 AM IchGucksLive: hi
10:12 AM IchGucksLive: it is thunder in paradise but no rain so far
10:12 AM IchGucksLive: all forest camp in full 360 rotation mode
10:12 AM IchGucksLive: loking for firerplumes
11:33 AM laminae: Hey guys, i'm modifying my c-beam cnc router to a flood carbon plate cutter, i'm thinking this is just another cheap Chinese spindle but is it worth the cost? https://www.amazon.com/gp/product/B06VY6PM6N/ref=ox_sc_act_title_1?smid=A16P4TUM521SQ8&psc=1
11:34 AM laminae: WOuld be kinda handy to control the vfd through lcnc but that's not really all that significant to me
11:47 AM gregcnc: you can't get much cheaper than the China spindles
12:23 PM fragalot: Hey
12:24 PM phipli: ho
12:24 PM fragalot: phipli: what'd you call me??
12:24 PM phipli: heh
12:25 PM phipli: fragalot, the chemical symbol of Holmium?
12:26 PM fragalot: oh, well then you should have capitalized it properly
12:27 PM phipli: I will make sure I do in future :)
12:35 PM IchGucksLive: hi all
12:42 PM IchGucksLive: a Question i wrote a android app for live walking in a deep forest orientation
12:43 PM IchGucksLive: can someone WILL someone test it
12:43 PM IchGucksLive: android
12:43 PM IchGucksLive: the debug tablet does it
12:43 PM IchGucksLive: i can give the apk
12:43 PM IchGucksLive: to manuell install
12:49 PM JT-Shop: hey phipli how's it going?
12:51 PM phipli: hey
12:51 PM phipli: not too bad
12:52 PM phipli: worked from home this afternoon to keep an eye on the beast
12:52 PM phipli: yourself?
12:55 PM IchGucksLive: Michael-gsc, online
01:02 PM JT-Shop: not bad, still messing with this shower pan, had to pull it up and remove the mortar the second time lol
01:02 PM JT-Shop: plywood filler swelled up and raised the pan during the night
01:02 PM JT-Shop: how's the sick one?
01:03 PM phipli: she's actually getting better
01:03 PM phipli: wish she'd eat more
01:03 PM phipli: she's started talking to me for the first time in a week and a half
01:03 PM phipli: quietly and a little feebly
01:03 PM miss0r: Goodevening
01:03 PM JT-Shop: wow that sounds good
01:04 PM phipli: she's lost a lot of weight though
01:04 PM JT-Shop: is she eating on her own?
01:04 PM phipli: a bit
01:04 PM phipli: not enough
01:04 PM phipli: I wish she was stuffing her face
01:04 PM phipli: she was trying to eat a load of shell (from grit) earlier, but kept missing
01:05 PM phipli: evening miss0r
01:05 PM phipli: she tends to enthusiastically eat for a few minutes... then looks really uncomfortable, shuts her eyes and wont eat
01:05 PM JT-Shop: I've been trying to figure out a way to put a grass catcher on my riding mower for the compost bin... finally came up with a redneck solution http://gnipsel.com/images/chickens/misc/grass-catcher.jpg
01:06 PM phipli: and it doesn't come off?
01:06 PM JT-Shop: at least she is eating, still giving her antibiotics?
01:06 PM phipli: yeah
01:06 PM JT-Shop: I added a string on the front to hold it on after that photo
01:06 PM JT-Shop: the string on the end is so I can dump it from the seat
01:07 PM * JT-Shop goes to try and fit the shower pan in with the concrete board in place
01:07 PM MarcelineVQ: I like that solution. they do sell mulching plugs for mowers, though I've not had great luck with them
01:08 PM MarcelineVQ: seem to clog quite easily
01:08 PM miss0r: I just got a package(just in time) containing a 4m long magnet flex strip, for a single axis DRO. I'm excited to test it out at the clients place tomorrow. It doesn't need anything more flat than regular bar stock, it is self adhesive and rumour has it, it will stick to anything forever, if you clean the surface properly. Also the DRO itself runs on batteries for 2 years, without locing its location
01:09 PM miss0r: And it is damn cheap. acurate within 0.01mm
01:10 PM fragalot: miss0r: but.. what about the read head?
01:10 PM miss0r: its tiny ! :D
01:10 PM IchGucksLive: miss0r, link
01:10 PM fragalot: also - got it just now, to install tomorrow :P the pattern!
01:10 PM miss0r: IchGucksLive: I don't have a link. I did it the old fashion way and called someone to place an order :]
01:10 PM miss0r: fragalot: Spring time in Denmark is hopeless with all the holydays
01:11 PM miss0r: I keep forgetting to calculate those in
01:11 PM fragalot: sounds familliar xD
01:11 PM miss0r: IchGucksLive: its made in germany by ELGO Electronic
01:11 PM miss0r: yeah yeah yeah
01:12 PM miss0r: They even included a C battery :D
01:13 PM IchGucksLive: miss0r, best for lathe
01:13 PM fragalot: Today I found out that a lot of invoices and other important documents get delivered to the wrong house because my address is so long
01:13 PM IchGucksLive: miss0r, where did you buy it
01:13 PM miss0r: IchGucksLive: Sure, but it will do just fine for an ajustable end-stop on a saw
01:13 PM IchGucksLive: miss0r, direct store or in the bya
01:13 PM fragalot: noticed when I got a fedex email saying package was delivered, yet I didn't receive anything
01:13 PM miss0r: IchGucksLive: from a place called TP group
01:14 PM miss0r: fragalot: So where did it end up?
01:14 PM fragalot: miss0r: my house number is 2 digits, printed address only had first digit
01:14 PM gloops: i got an old german made bench saw yesterday, someone selling the house getting rid of stuff - made by AL-KO - think that was east german
01:14 PM JT-Shop: MarcelineVQ: I used to have a mulching plug on there but yea it plugs up due to being plastic
01:15 PM fragalot: miss0r: judging from the pile of letters I got from going there.. this has been an issue for quite a while with quite a lot of different companies
01:15 PM miss0r: fragalot: Have you gone to the other adress and asked for your stuff?
01:15 PM miss0r: lol
01:15 PM fragalot: yeah, that's why I now know that's a problem, lol
01:15 PM fragalot: and i'm not the only one either.. all 10 houses with 2 digits starting with that one digit apparently get stuff delivered there
01:15 PM fragalot: RIP single digit houses in this street, lol
01:16 PM miss0r: hehe.. I think it is fair that companies only allow one digit in the streets in belgium... I mean, the country is tiny enough to only have one digit
01:16 PM miss0r: :P
01:17 PM MarcelineVQ: JT-Shop: we've got so much grass here that it would be more trouble than it's worth to actually collect it so mulching is neccesary, it sure cuts down the mowing quality though. there's really no comparison between when I have it off or on, it's night and day
01:17 PM fragalot: miss0r: :-)
01:17 PM IchGucksLive: miss0r, can you give me a idee of the cost
01:17 PM IchGucksLive: 1meter
01:17 PM MarcelineVQ: I think it's airflow more than anything, mower can't pull up the grass t cut it with the plug in
01:18 PM miss0r: IchGucksLive: yeah, Let me look at the mail with the quote, hang on
01:19 PM miss0r: IchGucksLive: ~80eur/meter. The reader head with DRO is 275EUR
01:20 PM IchGucksLive: thanks
01:20 PM miss0r: they sell it in 0.5m increments
01:23 PM JT-Shop: yippie the shower pan finally fits over the cement board...
01:24 PM JT-Shop: MarcelineVQ: I have 9 acres but mostly woods with some select spots to mow as well as the trails
01:25 PM JT-Shop: anyone know how to kill/clean algae from a bird bath without killing my birds?
01:25 PM MarcelineVQ: is it large enough to put an algae eating fish in?
01:26 PM JT-Shop: no, it's a regular bird bath maybe 20" across
01:27 PM MarcelineVQ: I'd be inclined to chlorinate once in awhile in the evening
01:27 PM MarcelineVQ: done lightly it should be gone by the morning
01:28 PM MarcelineVQ: but then I'm not sure how resillient algae is to that, I've not owned a pool to find out :X
01:28 PM JT-Shop: good idea, it maybe holds a gallon of water so a a teaspoon of bleach?
01:30 PM IchGucksLive: gn8
01:30 PM MarcelineVQ: at most
01:30 PM JT-Shop: I can flush it out before I let the girls out in the yard
01:30 PM JT-Shop: just to be sure..
01:30 PM MarcelineVQ: you can just dip your finger and sniff, no smell no problem
01:30 PM JT-Shop: yep, we had a small chlorine leak in a fresh water tank once a bit more than normal and you sure could smell it
01:31 PM JT-Shop: we had to chlorinate it because we had reverse osmosis water plants that was on an offshore jack up drilling rig
02:13 PM Tom_L: https://www.amazon.com/gp/product/B06VY6PM6N/ref=ox_sc_act_title_1?smid=A16P4TUM521SQ8&psc=1
02:13 PM Tom_L: someone posted that earlier but my question is, do they have any torque at low speeds?
02:14 PM Tom_L: it says 0-24k rpm which it fine for routers but what about lower speeds?
02:18 PM gregcnc_: they are more like 8-24kRPM
02:18 PM Tom_L: i figured as much but how's the low end torque?
02:19 PM Tom_L: or since it's BLDC would it be constant current with variable frequency?
02:20 PM gregcnc_: itsn't not BLDC, it's an induction motor
02:20 PM Tom_L: ok
02:21 PM gloops: never tried cutting with mine at low speed, like below a few thousand rpm
02:22 PM Rab: I'm not sure why anybody would buy the 110V instead of the 220V version, unless there was a real problem finding a 220V circuit. 2.2KW (alleged) @ 110V = 20A, that's a special 110V circuit anyway.
02:23 PM gloops: you can alter the torque curve to give more at low rpm, i think about 20% of torque can be shifted around
02:24 PM Rab: Real-world factors and power dissipation in the VFD mean the spindle is unlikely to develop 2.2KW anyway.
02:24 PM gregcnc_: no real specs means we'll never know
02:25 PM gloops: i cut .1 mm passes with 800w spindle, probably do more but i havent play with ally much
02:25 PM gloops: played
02:25 PM gregcnc_: 20% of almost nothing =?
02:26 PM gloops: well people cut ally very well with those spindles, thats all i know, watch the vids on youtube
02:27 PM gregcnc_: very well is up for discussion, but yes they work for most needs
02:31 PM miss0r: fragalot: Your internet connection is getting worse
02:33 PM gloops: https://www.youtube.com/watch?v=ez20r-hDZw4
02:33 PM gloops: you should know gregcnc you dont want low rpm for ally, you want high feed!
02:34 PM gregcnc_: you do with what you have, there are plenty of ways to make parts
02:39 PM gloops: half inch 4 flute - way too slow id say https://www.youtube.com/watch?v=-i_K6lhi154
02:40 PM gloops: oh thats wood
02:40 PM miss0r: it IS a pretty long endmill, with alot of contact...
02:40 PM miss0r: On a aluminium router. I wouldn't run faster
02:40 PM fragalot: miss0r: seems so.. I don't notice it, but it seems to be unable to maintain a permanent connection to something
02:40 PM fragalot: also - it's REALLY annoying to scrape beyond 40 points
02:41 PM gloops: whats the logic of using a 4 flute slowly for that task?
02:41 PM fragalot: damn thing sticks to the granite table harder than if it were a real vacuum table
02:41 PM gregcnc_: tha'ts some soft aluminum
02:41 PM miss0r: gregcnc_: I was referring to the cnc construction
02:41 PM miss0r: fragalot: Picture or it didn't happen :)
02:42 PM gloops: looks like its burning it to me, which it would
02:42 PM miss0r: your came is HD enoug, that is should be able to show suction :P
02:42 PM miss0r: s/came/cam
02:42 PM gregcnc_: the aluminum the router was cutting looked pretty soft
02:42 PM miss0r: gregcnc_: The notorious plyaluminium
02:43 PM gloops: lol, well aluminium is aluminium isnt it?
02:43 PM miss0r: gloops: Hell no :)
02:43 PM fragalot: miss0r: impossible to get a good picture as I can barely see the spots myself... couldn't get blue canode, so making do with yellow & red
02:43 PM miss0r: fragalot: :D
02:43 PM fragalot: and then to get the 40 spots, I need to put it on a clean granite again to hilight the absolute highs
02:43 PM gloops: it was only thing sheet, people post vids on facebook showing their routers hogging ally out
02:44 PM gloops: thin sheet
02:44 PM gloops: they drop the feed when the machine isnt rigid enough
02:48 PM miss0r: fragalot: Sounds like its gonna be pretty flat when you are done
02:48 PM fragalot: miss0r: also, single shot oilers showed up for the RF45... now I definitely need to fix it xD
02:48 PM miss0r: when yoy get bored with that biax of yours, just send it to me ;)
02:48 PM fragalot: miss0r: it /IS/ flat already.. I don't think I can get it any better :P
02:48 PM fragalot: 40 points, about~40ish % coverage... I can live with that.
02:48 PM miss0r: pffft
02:49 PM miss0r: You can live with it, when you have lapped the surface to a 0.001Ra
02:49 PM fragalot: don't have a surface roughness tester, nor comparison blocks :P
02:49 PM miss0r: :] time to go get'em
02:49 PM fragalot: :D
02:49 PM miss0r: and send it to me when you are done playing with it
02:49 PM miss0r: :D
02:49 PM fragalot: I can't see a micrometer move when I sweep it across. Good enough.
02:49 PM fragalot: haha :D
02:50 PM fragalot: shall I get an electronic height gauge whilst i'm at it?
02:50 PM miss0r: sure, but why stop there? get an electron microscope to locate the last of the high spots
02:50 PM miss0r: and some sort of high precision laser to burn them off
02:50 PM fragalot: :-)
02:50 PM miss0r: is that a 0.001mm dial gauge?
02:51 PM miss0r: you 'should' see some movement of the needle, otherwise the scraping it not doing its thing ;)
02:51 PM fragalot: no, 0.01
02:51 PM miss0r: ahh
02:51 PM fragalot: still need to get a 0.001 at some point or another
02:52 PM miss0r: meh.. Most of the time they just piss you off... Like when you grap it by mistake, and use it to line the vise up on the mill, without knowing you are using a 0.001mm gauge
02:52 PM fragalot: :D
02:52 PM miss0r: I started cursing... I seriously couldn't get the thing within what I thought was 0.005...
02:53 PM fragalot: on the rf45 you couldn't even get it square to within .1mm
02:53 PM fragalot: so don't worry too much
02:53 PM fragalot: xD
02:53 PM miss0r: Then I saw the incrimental mark.. then I actualy laughed, realizing just how acurate I ended up setting it
02:53 PM fragalot: (tramming in worked great down to no needle movement on 0.01mm,... until you checked tram on a different spot on the table.
02:53 PM fragalot: hehe
02:54 PM miss0r: hehehe
02:54 PM miss0r: Brb, I need to go pick up some stuff
03:04 PM gloops: i remember him building this, he pushed the spindle to the limit but cant see those vids - stalled 1.5kw in ally a few times, didnt seem to hurt it though https://www.youtube.com/watch?v=ieCal_oUsI4
03:04 PM gloops: he did ok with grbl, 400 ipm
03:35 PM gloops: 'The dawn of a new era' #F35UK fighter jets LANDED in UK TONIGHT http://bit.ly/2xLlSJO
03:35 PM fragalot: so it IS able to do something after all?
03:35 PM gloops: we are strong!
03:36 PM gloops: fragalot this is the most advanced fighter ever
03:36 PM fragalot: it's the most overpriced and expensive piece of kit ever too
03:36 PM gloops: now our carrier..can carry lol
03:36 PM fragalot: which is a jack of all trades, but a master of none
03:37 PM SpeedEvil: We should just 3d print 1000 A10s and F16s.
03:37 PM gloops: well, historically, it doesnt compare to the airborne legends built by britain of course
03:37 PM gloops: but it will put us on for a while
03:37 PM fragalot: it's had it's but kicked by a 40yr old F16
03:38 PM gloops: malicious rumours
03:38 PM SpeedEvil: I wonder what the pullout cost of the contract is.
03:38 PM fragalot: well, that wasn't a rumor.. that actually happened.
03:38 PM fragalot: of course, it could just as well be the pilot that made the difference
03:39 PM gloops: Speedevil RR made the turbine rotors
03:39 PM fragalot: and the pilot blamed the f35 not being outfitted with the high-end expensive sensors and helmet, and the fact that it's more sluggish than the F16
03:39 PM gloops: it was only during early test flights, these f35s are ok
03:40 PM fragalot: they better be for the price
03:40 PM gloops: im i detecting a whiff of envy here fragalot?
03:40 PM fragalot: belgium's ordered some too
03:41 PM fragalot: and it's caused a political shitstorm for all parties which is quite sad :P
03:41 PM gloops: the typhoon didnt really get going
03:41 PM fragalot: (army pushed to get F35, but withheld information which was proven in emails sent anonymously, along with later proof that those emails were potentially fake, so both sides of the argument are in deep shit atm :P)
03:42 PM SpeedEvil: If in fact the BFR gets working, things could be odd.
03:42 PM fragalot: and the information they (supposedly) withheld, wouldn't make much of a difference anyway
03:42 PM SpeedEvil: 1000 ton conventional warheads out to several hundred kilometers.
03:43 PM XXCoder: take few f16s, adopt it to burn money as fuel
03:43 PM XXCoder: its still cheaper than f35
03:43 PM fragalot: lol
03:44 PM gloops: Sppedevil no good in todays warfare
03:44 PM XXCoder: not kidding, f35 is amazing expensive
03:44 PM gloops: no accuracy
03:45 PM gloops: brimstone missile can put the same cargo up your exhaust pipe
03:45 PM SpeedEvil: gloops: ton was not a typo
03:47 PM gloops: well, its a formidable thing, but what scenario would see it deployed?
03:47 PM gloops: unless we're trying to flatten berlin or something
03:47 PM fragalot: I'm just a tad sceptical about the 'this thing will be able to do everything'
03:48 PM SpeedEvil: gloops: Sometimes it just needs flattening.
03:48 PM fragalot: and am wondering if they couldn't have made 2 or even 3 separate things specific for the 3 tasks it's capable of doing, which would perform better at those tasks, at a similar, or only a bit more
03:48 PM fragalot: cost*
03:49 PM gloops: agreed, berlin does need flattening sometimes
03:49 PM fragalot: beasts like the SR71, or the A10,.. one trick pony's, but by god they are unparallelled.
03:50 PM SpeedEvil: http://www-cdr.stanford.edu/intuition/Slough.html /me is reminded of.
03:51 PM gloops: im not sure our f35s even have vertical take off
03:51 PM fragalot: gloops: question is: do they really need it? does it benefit the UK in any way?
03:51 PM fragalot: VTOL is useful on carriers.. which are slowly going out of style anyway
03:52 PM gloops: well, we invented vertical take off of course, with the harrier jump jet - yes proved crucial in many operations
03:52 PM gloops: as in - where landing strip has been bombed
03:54 PM gloops: and when the UK did it - no computers
04:02 PM gloops: SpeedEvil people got a bit spooked when they first saw formations of bombers flying over all the time
04:04 PM gloops: even before the war, planes had been rarely seen, suddenly you have loads of planes - and planes that carry WMD - also unknown
04:05 PM gloops: before that armies would march out into a field in a gentlemanly manner to slaughter one another
04:05 PM fragalot: and take turns shooting
04:05 PM gloops: now the prospect of entire cities being levelled appears
04:06 PM gloops: fragalot yes returning fire before your opponent had finished was damn unsporting
04:08 PM devlap: Got all my axis tight, going to give her another test pattern to try
04:09 PM gloops: excellent, keep us posted devlap
04:09 PM devlap: running leveler.
04:09 PM devlap: The axis moves as good as I can measure.
04:14 PM gloops: well, if you are cutting these very fine cuts it needs to be spot on
04:20 PM Deejay: gn8
04:21 PM devlap: Fine like dat azz.
04:25 PM flyback: <flyback> "this antibiotic may make your go blind, BEND OVER"
04:25 PM flyback: <flyback> nice

04:29 PM gloops: 8000rpm, 3400mm/min
04:30 PM gloops: like going through ice cream
04:30 PM Rab: Convincing music, furiously adding to cart
04:30 PM XXCoder: I hate it when machine changes position on all 3 axis at once
04:30 PM XXCoder: extremely diffult to see where its going
04:32 PM XXCoder: those videos is pretty well done
04:33 PM XXCoder: (I am deaf, remember)
04:34 PM gloops: well for this, i havent got headphones plugged in lol
04:35 PM syyl: there is no machining noise anyway
04:35 PM syyl: they overlayed it with music
04:36 PM syyl: (most of the time they do that for a reason ;) )
04:36 PM XXCoder: lol
04:41 PM miss0r: looks like a great surface finish, especially for something moving that fast
04:43 PM miss0r: syyl: I think you might appreciate my EDM project: https://imgur.com/a/kwmfVgf
04:43 PM syyl: yay!
04:43 PM syyl: tapbuster?
04:43 PM miss0r: yeah
04:43 PM syyl: are you going for the flemming electronics?
04:44 PM miss0r: Not realy. I cooked up something of my own
04:44 PM syyl: nice
04:44 PM syyl: i have his two books sitting hear forever
04:44 PM syyl: but meh
04:44 PM syyl: .D
04:44 PM theCockerel: syyl: No dice to roll.
04:44 PM syyl: oh wtf, this channel has a dicebot?
04:44 PM miss0r: 1200watt of power. I haven't tested the new 'spindle' there. but the proto-type did pretty good
04:45 PM devlap: dialing the z in on these v bits is a pain
04:45 PM devlap: its taking just a little too wide of cuts.
04:46 PM miss0r: wtf is a dicebot? :D
04:46 PM devlap: d20
04:47 PM devlap: .d20
04:47 PM gloops: any flat on the v bit devlap?
04:47 PM syyl: .D6
04:47 PM syyl: .D 6
04:47 PM theCockerel: syyl: You roll 6: 6 = 6
04:47 PM devlap: not that I can see with my naked eye, its supposedly a .1mm 10*
04:47 PM devlap: let me put it under the amscope
04:48 PM gloops: some bits have a small flat on the bottom - i find you get a wider cut with those
04:48 PM devlap: it doesnt come to a point
04:48 PM devlap: it goes flat, probably .1mm there i am guessing
04:49 PM miss0r: The idea with my EDM is that I can take it with me. The PSU unit 'only' weighs 12kgs. and the buisness end unit there weighs aroung 5kgs.
04:49 PM gloops: so youre touching off to that
04:49 PM miss0r: So I can go to whoever breaks a tap on something big & heavy and take care of it on the spot
04:49 PM gloops: not where the v angles would have converged
04:49 PM DocHopper: Hey linux cnc, trying to write some manual gcode, anyone have a good guide to cutting circles with G02 or G03?
04:50 PM devlap: gloops, yea I G92 Z0 on that probe touching the flat area
04:50 PM devlap: going to run a job with half the z cut depth and see how that goes
04:51 PM gloops: https://www.cnccookbook.com/cnc-g-code-arc-circle-g02-g03/
04:54 PM gloops: DocHopper tried that one?
04:54 PM DocHopper: gloops: Looking now, thanks.
05:12 PM devlap: The difference between polishing the copper and wiping out the entire cu layer is pretty finicky.
05:12 PM devlap: tried 0.05 depth, and copper gets mangled in one direction, 0.025 depth gets my shiny copper drawings.
05:13 PM devlap: half thou.
05:17 PM gloops: lol, glad i use wood
05:19 PM devlap: Once I get the process down I don't think it'll be too bad.
05:19 PM SpeedEvil: Copper thickness on PCBs is about a couple of thou.
05:20 PM devlap: I'm using FR1 right now.
05:20 PM devlap: not sure how many oz the copper layer is
05:21 PM SpeedEvil: For standard thickness.
05:21 PM SpeedEvil: It would be unusual for it to be other than 1oz/sqft = 1.4 thou
05:21 PM SpeedEvil: Which is fun, as most PCB isn't going to be flat to that level
05:22 PM devlap: That's why I probe and compensate.
05:22 PM devlap: Otherwise I'd have half air cut, half hole in board.
05:22 PM devlap: I'm getting consistent cuts now.
05:25 PM Rab: devlap, 0.5mm pad pitch on FR1? You'll want to use low soldering heat, copper tends to delaminate from that stuff.
05:25 PM gloops: any videos of this cutting youre doing devlap? sounds ineresting
05:26 PM devlap: Can take one.
05:27 PM devlap: https://tinyurl.com/yc9jt8u8 photo of run in progress
05:28 PM devlap: The rectangle is with the bad Y
05:28 PM devlap: The left one is my base depth, the shiny one is G92 Z-0.25, the current one, it looks too deep as well, is G92 Z0.25
05:28 PM devlap: err 0.025
05:30 PM devlap: hmm im getting uneven cutting on this one.
05:30 PM gloops: if im seeing right, the shiny one has gone through in places
05:31 PM gloops: this looks quite a challenge
05:31 PM devlap: I need to microscope it.
05:31 PM devlap: I havent taken it off and its not easy to see in situ.
05:31 PM devlap: I'm about to finish the last pass, ill amscope it.
05:32 PM devlap: I'm not sure why this one is half air cutting again, either z slipped, which I don't think is the case, or I had an error in the auto leveling process, or maybe the tip cracked.
05:33 PM gloops: looking at the material seems to be some variation in thickness and flatness yes
05:33 PM devlap: for sure its not flat
05:34 PM Tom_L: gloops, those cutters earlier (i'm still catching up) appear to have excellent chip evacuation
05:36 PM Rab: devlap, you might get better results using double-sided tape for hold down instead of the corner clamps.
05:39 PM gloops: Tom_L i googled them but didnt come up with any prices
05:39 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Seb/Endmills.jpg
05:39 PM Tom_L: i got some high helix but not that high the other day
05:39 PM Tom_L: the one in the middle
05:40 PM gloops: expensive?
05:40 PM Tom_L: nothing special about their cutters, just high helix
05:40 PM Tom_L: $20 per
05:40 PM gloops: oh thats ok
05:40 PM Tom_L: carbide
05:40 PM Tom_L: .25"
05:41 PM Tom_L: high helix and high rpm
05:41 PM gloops: slinging the chips out everywhere, the nice finish maybe has something to do with the machine itself though
05:41 PM Tom_L: probably
05:41 PM Tom_L: any decent machine with any decent cutter could do that
05:42 PM Tom_L: i've seen mori seki cut 1/4" cuts with a shell mill like it was butter
05:42 PM Tom_L: chips stuck to the paint inside the enclosure :)
05:43 PM gloops: i doubt ill be doing quarter inch cuts lol
05:43 PM gloops: but yeah any machine made for metalwork
05:43 PM Tom_L: no coolant
05:43 PM Tom_L: on your spindle, is it analog control?
05:44 PM Tom_L: or modbus or what?
05:44 PM gloops: linuxcnc controls it, there is limited control from the vfd panel
05:44 PM Tom_L: oops, gotta run..
05:44 PM Tom_L: lost track of time.
05:44 PM gloops: im going to bed anyway
05:48 PM devlap: Got microscope pics in a sec
05:52 PM devlap: https://www.yogile.com/u6cshi2ofyb/41m/share/?vsc=OTlmMWE2Y
05:54 PM devlap: Rab, why should the tape do better? clamps deflecting the material?
05:54 PM Rab: devlap, that's what I'm thinking.
05:54 PM devlap: I figure the leveling would compensate enough for it.
05:55 PM Rab: That force on the edges is causing the material to bow up in the middle.
05:55 PM devlap: I'm doing probe every 1mm
05:55 PM Rab: What's your Z resolution?
05:55 PM devlap: so theres 100 probe points on that 10m square.
05:55 PM devlap: 10mm*
05:55 PM devlap: uhh z res one sec
05:55 PM jesseg: ahh PCB .... I didn't have much success with fine pitch PCB routing, I suspect due to head flexibility and the head "pulling"
05:56 PM jesseg: and the copper wanting to go weird and peel up inbetween route paths :P
05:56 PM devlap: LQFP100 is probably the limit of possible.
05:56 PM devlap: for this setup
05:56 PM devlap: or just beyond it :)
05:56 PM jesseg: I ended up using a carbide scribe point to scratch a layer of candlewax then etching it with ferric chloride for finer pitch than about 20tpi :P
05:57 PM devlap: yea I've considered UV process before.
05:57 PM devlap: It looks like I'm 5mm/rev with 200.0 steps x 4 micro stepping.
05:57 PM devlap: 160.0 steps / mm
05:58 PM devlap: quarter thou per step
06:01 PM devlap: https://s3.amazonaws.com/image.yogile.com/u6cshi2ofyb/12c578sem5de-extra_large.jpg?1528323395 it looks like it left some traces here
06:01 PM Rab: Pretty good in general terms, but if your desired depth is .0005" then half of that is still pretty coarse for auto leveling, right?
06:02 PM devlap: I run the leveling at F2.5 hahaa
06:02 PM devlap: yea its coarse for sure.
06:03 PM devlap: Can try microstepping more on the z
06:03 PM Rab: So I don't know if auto leveling is a substitute for the board actually being as flat as possible.
06:06 PM devlap: https://othermachine.co/assets/dsbetaimage07.jpg they get boards looking like this
06:06 PM devlap: they dont know smd for sure :P
06:25 PM devlap: maybe the micro endmill is where its at.
06:26 PM devlap: idk, been a good adventure. I know I can probably do anything bigger than LQFP
06:31 PM devlap: Ordered some two sided tape Rab.
07:03 PM ziper: what is the point of the little washers for a dial bore gauge?
07:59 PM enleth: is 5/8-18 a "typical" imperial machine thread?
08:01 PM enleth: I misplaced one nut when taking the bridgeport head apart, the threaded part of the shaft it goes on appears to be 15.8-15.9mm and fits a 18G pipe thread gauge which is the only imperial thread gauge I have
08:02 PM enleth: so it looks like it's 5/8-18
08:06 PM ve7it: looks like you got it... also known as unf see http://www.carbidedepot.com/formulas-tap-standard.htm
08:09 PM enleth: OK, apparently it's a very popular retaining nut size for lawnmowers, so gardening supply stores carry it around here
08:09 PM enleth: and they even have a flanged version
08:39 PM Tom_L: ace should carry those
08:40 PM gregcnc_: did Ace expand to Europe?
08:52 PM Tom_L: who knows
08:53 PM Tom_L: http://www.acehardwareintl.com/
08:53 PM Tom_L: apparently so
08:54 PM Tom_L: no where near him
09:14 PM CaptHindsight: will_handle: what files (.ini and .hal ?????) are needed to get linuxcnc back after disk crash
09:14 PM CaptHindsight: did he get his system back up?
09:46 PM enleth: Tom_L: we've got a local ebay/amazon-like site here that aggregates sellers for pretty much absolutely everything, including generic hardware like nuts and bolts
09:47 PM CaptHindsight: radio Shack could have done similar with the top 200 alibaba products
09:48 PM enleth: and local means the sellers are local too, I'll get that nut on Friday
09:48 PM CaptHindsight: but I think that the trade deal on China shipping to the USA is less than the cost of postage within the USA
09:51 PM CaptHindsight: I've been finding more sellers on ebay that are just USA based warehouses for China goods
09:51 PM CaptHindsight: the prices without shipping are about the same as the Chinese price plus shipping to the USA
09:51 PM enleth: not the case here, dropshipping is actually frowned upon and must be indicated very clearly
09:52 PM CaptHindsight: the local warehouses just get it to you a bit quicker
09:52 PM enleth: "a bit" sounds like an understatement
09:52 PM enleth: two days vs. two weeks is not "a bit"
09:52 PM CaptHindsight: for me it's a bit
09:53 PM CaptHindsight: lets not argue over semantics, how about pro wrestler names instead?
09:54 PM enleth: I'm not particularily well versed in the names of sweaty guys who pretend to beat each other to a pulp

10:44 PM Tom_L: have we stooped to a new low here?
10:46 PM jdh: looks that way
10:54 PM RyanS: we talkin' bout wrastlin' <said in redneck voice>
11:10 PM CaptHindsight: pro wrestling is a big step up for the usual in here
11:11 PM CaptHindsight: much better subject to argue about than semantics
11:12 PM jdh: welding galvanized?
11:12 PM RyanS: cancer
11:12 PM RyanS: no thanks
11:12 PM CaptHindsight: Roguish: I enjoyed it back in the 60's-70's on B&W TV preferably on a UHF channel
11:13 PM flyback: uh no
11:13 PM flyback: it won't give you cancer
11:13 PM flyback: STUPID CANUCK
11:14 PM flyback: zinc fumes are not carcenigetic
11:14 PM CaptHindsight: welding galvanized with a cnc router that you can't decide what model to buy
11:14 PM flyback: you will feel like they are for a week but that's it
11:14 PM RyanS: it's toxic though isn't it
11:14 PM flyback: not escpically
11:14 PM CaptHindsight: https://en.wikipedia.org/wiki/Metal_fume_fever
11:14 PM flyback: it's bad in the body but there's no perm danger
11:14 PM flyback: it flushes out
11:15 PM flyback: but it's to be avoided at all cost
11:15 PM flyback: because it's miserable like my asscrack cyst
11:16 PM flyback: if you do it enough times it will become a problem though
11:16 PM CaptHindsight: most illnesses that start with the asscrack version are usually benign
11:16 PM CaptHindsight: asscrack flu, asscrack fever etc
11:17 PM flyback: there's so many guides how to weld galvanized safely or not to remove the galvan then readd it after
11:17 PM flyback: there's no reason to risk getting it
11:17 PM CaptHindsight: easily avoided with a plastic bag and rubber band
11:18 PM CaptHindsight: a dry cleaning bag may be used as a spacesuit costume when in a pinch
11:21 PM RyanS: sounds like the argon suicide method
11:41 PM nallar is now known as Ross
