04:12 AM Tom_L: morning
04:12 AM XXCoder: hey
04:12 AM XXCoder: TurBoss: hows things
04:13 AM Tom_L: JT-Cave-, that last pdf i posted might do some good
04:14 AM TurBoss: good morning XXCoder
04:14 AM Tom_L: http://www.illianaindtech.com/PartsBook3-14-14/Web%20Page/Manuals/3300mk/70000418C.pdf
04:14 AM XXCoder: hows things
04:14 AM Tom_L: P 15
04:27 AM TurBoss: fine
04:27 AM XXCoder: thats good :D
04:28 AM TurBoss: got a set of 3 small 180w servos waiting for membrane couplers
04:28 AM TurBoss: :D
04:29 AM TurBoss: thoose JMC servo motors
05:20 AM JT-Cave-: morning
05:20 AM XXCoder: :) whats those servos for?
05:29 AM TurBoss: little cnc engraver
05:29 AM XXCoder: awesome. wood and metals or wood and plastics only?
05:32 AM XXCoder: or circuit boards?
06:15 AM TurBoss: wood plastics and pcb and maybe aluminum
06:15 AM XXCoder: nice hope alum is a success
07:24 AM JT-Cave- is now known as JT-Cave
07:49 AM Tom_L: partly cloudy high 90F
07:53 AM JT-Cave: we get that friday
07:53 AM Tom_L: did that pdf help any?
07:54 AM JT-Cave: I didn't see anything in there that applied to my situation
07:54 AM JT-Cave: thanks for finding it
08:50 AM Loetmichel: *giggle* My coworkers just stepped onto the shipping scale (one after the other)... 56kg... 72kg... 87kg...92kg.. 96kg.. $me puts ONE foot on the scale... BEEP--FULL--BEEP--FULL--BEEP--FULL--BEEP--FULL-- :) (I am at 111kg atm) :D
08:52 AM CloudEvil: :)
10:10 AM Rab_: testing
10:22 AM JT-Shop_ is now known as JT-Shop
10:29 AM JT-Shop: package I shipped apr 12 was delivered finally down under
10:33 AM JT-Shop: and a package I shipped on apr 22 has finally left the us
10:38 AM s6d7XSaB_ is now known as {HD}
11:23 AM Tom_L: JT-Shop, i bet that's a relief
12:32 PM JT-Shop: no relief until the bitch's package starts to move lol... yeah good to know they are starting to move
12:33 PM JT-Shop: have not heard back from spoiled boy in brazil after telling him I no longer ship there
12:45 PM CaptHindsight[m]: one of the down sides to selling on Amazon or ebay is tolerating demands from buyers that want refunds for shipping issues not under your control
01:15 PM JT-Shop: yep that's another good reason to NOT sell on flea bay and amazon
01:20 PM cloudevil_: If you're a corporate entity, it's generally your fault 100% until package hits end user.
01:29 PM * JT-Shop is glad he is not a corporate anything
01:33 PM * JT-Shop starts cleaning off table #2
01:35 PM Tom_L: there's a table under all that?
01:48 PM JT-Shop: IIRC yep
01:56 PM * JT-Shop figures he has 6 months to clear out the garage for the 2021 ridgeline but by then they will be shipping 2022's
02:06 PM CaptHindsight[m]: (not looking for an argument) what put Honda on the top of your list?
02:08 PM skunkworks: great way to start a converstaion...
02:08 PM skunkworks: ;)
02:08 PM CaptHindsight[m]: I've only had one with 2 wheels :)
02:08 PM skunkworks: I had a honda accord for a short time.. 1988 iirc
02:09 PM skunkworks: I have a toyota corolla that has 250K and original clutch 2006
02:11 PM CaptHindsight[m]: Land Cruiser here with 330K miles, '94
02:14 PM CaptHindsight[m]: I drove some Jeeps into the ground, usually with continual differential problems
02:14 PM JT-Shop: I like the features and gas mileage of the ridgeline and we have had honda vehicles steady since 09
02:14 PM skunkworks: The kids love the toyota... makes them feel cozy...
02:14 PM skunkworks: 5 speed.. love it.
02:14 PM JT-Shop: got my first honda in `68
02:14 PM skunkworks: don't know what I am going to do when that finally dies...
02:15 PM JT-Shop: my chevy uplander is a piece of crap, I wouldn't own one if I didn't steal this one
02:16 PM skunkworks: we have a ford flex for travel.. It needs a transfercase
02:16 PM JT-Shop: rusty the 02 z71 truck is ok except for 15 MPG
02:16 PM JT-Shop: we use the wifes honda insight for travel over a few hundred miles
02:17 PM * JT-Shop continues the quest for the top of the work table
02:24 PM CaptHindsight[m]: https://i.imgur.com/PsZm9Fw.jpg front diff at 250K miles
02:24 PM CaptHindsight[m]: https://i.imgur.com/txAZgI6.jpg
02:25 PM CaptHindsight[m]: pulled the back one apart at 300K and it looked even better
02:26 PM CaptHindsight[m]: so I have all the parts for rebuilds maybe in another 100K
02:27 PM CaptHindsight[m]: i just cleaned, readjusted and used new seals, saved the bearings for later
02:27 PM CaptHindsight[m]: took the pics after a trip to NY and back and discovered that i only had sludge in the case vs oil
02:28 PM CaptHindsight[m]: was the consistency of warm cream cheese
02:30 PM CaptHindsight[m]: skunkworks: unless you can start pushing with your feet Fred Flinstone style I'd say keep them running
02:57 PM * JT-Shop just found work bench #2... 6 more to clean off
03:38 PM * Tom_L gives JT-Shop a bigger shovel so it will go quicker
03:39 PM Guest9189: would there be objections to porting LinuxCNC to Haiku OS, and if not would th4 project accept patches for upstream inclusion once completed ??
03:42 PM Tom_L: it probably would be as short lived as your visit here
03:44 PM andypugh: I found some relatively small engraved numbers on that eBay. £3.30 for 1 to 10, or £11.55 for 1 to 50
03:46 PM andypugh: So now I know which offset belongs to which lathe tool: https://photos.app.goo.gl/fKMjV9ELPznwoBj89
03:50 PM Tom_L: a sign you may have acumulated too much stuff
04:01 PM andypugh: Without a doubt
04:05 PM andypugh: I bought a 0-50 set for my milling tool holders. There are more than 30 of those.
04:05 PM Tom_L: andypugh, what draft angle do you use when making your castings?
04:05 PM XXCoder: hey andy
04:06 PM andypugh: I tend to use 2 degrees, unless that’s a real problem.
04:06 PM Tom_L: is that fairly standard?
04:06 PM Tom_L: my cad defaulted to 5
04:06 PM Guest9183: did anyone reply on my port question ? webchat keeps disconnecting
04:07 PM andypugh: 2 degrees is about tandard. 1 degree is about the minimum.
04:07 PM andypugh: Guest9183: I didn’t see the question, you disconnected as soon as I turned up.
04:07 PM Guest9183: draft angles vary with foundary and material, shallower is usually preferred
04:08 PM andypugh: Shallower as in bigger numbers?
04:09 PM andypugh: If you want to be less than 2 (and even at two) you need a good smooth surface.
04:09 PM andypugh: If you are 3d printing the pattern then I would probably use 3.
04:09 PM Tom_L: have you printed any of your casting parts?
04:09 PM Tom_L: ok
04:09 PM andypugh: Most of my patterns now are 3D printed.
04:09 PM Guest9183: i was wondering if there was significant opposition to porting linuxcb to haiku is, and when it's working if there'd be interst in keeping it upstream. Hainu has the QT5 toolkit, and a but one library iirc, i think the mesa 5i25 driver looks easy to port as well
04:10 PM andypugh: This was the most recent
04:10 PM andypugh: https://photos.app.goo.gl/ttpVKT6amwCNPsqm7
04:10 PM Guest9183: draft angle meaning corner radious ? large softer radius always preferred
04:11 PM Tom_L: i think i saw those results but i'm not positive...
04:11 PM Tom_L: what did you spray it with?
04:12 PM andypugh: Spray putty first, then red enamel. “Pattern Coat” epoxy paint works best, but it troublesome as you need to mix it and work fast.
04:12 PM Tom_L: wasn't that for your universal adapter?
04:13 PM andypugh: Guest9183: As I see it, the most likely problem with Haiki would be the realtime subsyste,
04:14 PM XXCoder: lol left pretty quickly
04:14 PM XXCoder: well hows things andy
04:14 PM andypugh: Things are OK, though more hours in the day would be nice.
04:15 PM XXCoder: nice. i got contacted for an interview for different company but reviews for that company is ehh so dunno
04:15 PM andypugh: Currently I am trying to make an unpickable lock. I could probably have finished it today, except I got scared of the final machining op, it could all go very wrong.
04:16 PM XXCoder: i saw a video about that. it was interesting
04:16 PM andypugh: “Stuff made here”?
04:16 PM XXCoder: it was calloration with lockpicking lawyer, dont remember more than that
04:16 PM andypugh: My design is based on that basic concept, but _much_ simpler.
04:17 PM andypugh: (The basic idea being to set the pins, then test them as a separate operation.
04:19 PM JT-Shop: some time back I blasted something that had some curls from drilling in the holes... kept plugging up the nozzle
04:19 PM JT-Shop: so I decided to drain the hopper and got a 5 gallon bucket and a pan and unscrewed the plug...
04:19 PM XXCoder: andy so cylinder would rotate only for some pins?
04:20 PM JT-Shop: the bucket is getting pretty full and the stream of media is not slowing down
04:20 PM JT-Shop: I'm thinking I didn't think this through very well
04:20 PM andypugh: XXCoder: Concentric cylinders
04:20 PM JT-Shop: even if the plug hadn't rolled away out of my reach there is no way to screw it back in
04:20 PM XXCoder: ok if youre making a ideo i want to see it evenually
04:21 PM XXCoder: jt doh
04:21 PM andypugh: I haven’t made a “making” video, but I will probably make one about it. Unless I decide to patent it :-)
04:21 PM JT-Shop: lucky for me there was a small box under there with brass scrap in it, so I lifted the pan up and slid the box under to stop the flow
04:22 PM XXCoder: andy if patenting, hope you succeed
04:22 PM JT-Shop: now I'm trying to decide if I want to sift the old media or not...
04:23 PM andypugh: Is it magnetic media?
04:23 PM XXCoder: jt sift what out?
04:25 PM Roguish_shop: hello all.
04:25 PM Roguish_shop: hey, what size standoffs are best for mesa boards? #4 or #6 or #8
04:25 PM JT-Shop: coal, sift out the fines and leave the unbroken media
04:25 PM XXCoder: hey
04:25 PM JT-Shop: M3
04:26 PM andypugh: Holes are 3mm
04:26 PM XXCoder: jt wonder if theres a way to do vibration size sorting
04:26 PM Tom_L: JT-Shop, use your compost sorter :)
04:26 PM JT-Shop: I was pondering taking it outside and in front of a fan pour from bucket to bucket
04:27 PM JT-Shop: that has 1/2" square openings
04:27 PM Rab_: Roguish_shop, #4 ought to be a good (close) fit for 3mm holes.
04:28 PM Roguish_shop: ok, thanks. yeah, #6 sort of threads itself in.... probably not the best.
04:29 PM JT-Shop: Roguish_shop, you try out the facing software yet?
04:30 PM Roguish_shop: JT-Shop, no, haven't had the opportunity yet. it looks pretty good and I definitely will.
04:30 PM JT-Shop: it does pockets now
04:30 PM Roguish_shop: finally got the ballscrews mounted in the PM940. now on to the electrical....oh joy.
04:30 PM JT-Shop: what fun
04:30 PM XXCoder: jt lol tjough i bet it can be automayed
04:31 PM JT-Shop: I guess I'll just order an ac servo from chinlee
04:31 PM JT-Shop: can't try it till Bambi gets done eating corn and apple slices
04:31 PM JT-Shop: she is just outside the shop door
04:32 PM JT-Shop: must be time to start cleaning work bench #3
04:32 PM XXCoder: basically 2 buckets, both with bottom bolt on holes
04:32 PM XXCoder: just have stands to hold em outside and one drains away
04:34 PM XXCoder: lol utterly unrelated channel, someome asked about haiku
04:34 PM XXCoder: not irc even. discord
04:51 PM JT-Shop: hmm over here we use SFM I wonder what the metric world uses to calculate drill speed?
04:52 PM andypugh: SMM
04:52 PM andypugh: (I use 80 for steel and 120 for aluminium)
04:53 PM andypugh: If I was turning Aluminum I would, of course, use SFM instead.
04:54 PM JT-Shop: Surface Meters per Minute?
04:54 PM andypugh: Indeed.
04:55 PM JT-Shop: thanks
04:55 PM JT-Shop: why use SFM for aluminum?
04:55 PM JT-Shop: turning aluminum
04:57 PM JT-Shop: my drill calculators have all turned out a bit clunky and needed you to type in stuff but the one I'm working on now you pick a radio button for units and material and have a couple of sliders to adjust depth per rev and surface speed
04:58 PM JT-Shop: hmm I need a deep hole checkbox too
05:05 PM andypugh: SMM for Aluminium, SFM for Aluminum.
05:05 PM andypugh: :-)
05:06 PM robert1: lol
05:12 PM JT-Shop: now I have to change the spelling of the materials if you select metric lol
05:15 PM Roguish: JT-Shop, I've been using HSMexpress in Solidworks. they have a pretty good drilling routine. it is basically a combination of g83 and g73. it pecks like g73 a few times for a set distance, them withdraws completely, then dives back down and pecks a few times again. repeated until full depth is reached. a lot quicker than g83 alone, but stills clears chips really well.
05:16 PM Roguish: it's actually written out explicitly with g1's and g0's.
05:16 PM Roguish: no actual g73's, or g83's
05:17 PM Roguish: i like it
05:17 PM JT-Shop: my drill routines use either G81 or G83
05:18 PM JT-Shop: sounds like a catch 22 SMM for Aluminum if you're a canuck and SFM if your a red neck
05:26 PM andypugh: XXCoder: You are, presumably, not an “Anglophone” as you don’t understand english speech. Have you ever heard a word that means “Can _read_ english?"
05:32 PM andypugh: Being totally distracted from what I was meant to be doing by this question, I found this (to me, at least) fascinating article about how “read” and “write” in English are unlike any other European language: https://medium.com/the-philipendium/word-connections-read-write-7df53111eb7d
05:39 PM XXCoder: andypugh: reading
05:42 PM XXCoder: interesting read
05:47 PM CaptHindsight[m]: moved to rural uhmerica a decade ago, now I have fun murder'n every bit of English I ever learnt
05:48 PM XXCoder: why not just drive till you see two houses closer than mile away from each other and move there?
05:49 PM CaptHindsight[m]: has to be more dense than that
05:49 PM XXCoder: nyc then lol kidding
05:49 PM CaptHindsight[m]: some towns out here have lower populations than single apartment buildings
05:50 PM CaptHindsight[m]: NYC is kinda medium big these days
05:52 PM CaptHindsight[m]: also kinda stuck here due to the ongoing plague
05:52 PM JT-Shop: houston is huge and full of thieves
05:52 PM XXCoder: tacoma is #1 crime city in wa. yay?
05:53 PM XXCoder: thats after massive cutdowns in 90s to 00s
05:53 PM JT-Shop: I'm glad I live on a dead end dirt road off of a dirt road in small town MO
05:53 PM andypugh: So, XXCoder Have you ever read an alternative for “Anglophone” without the sound-based root?
05:53 PM CaptHindsight[m]: I miss Tokyo
05:54 PM XXCoder: andy ahh its a book. nah not really interested in non-sci fi and fantasy books
05:55 PM JT-Shop: so I need an ac servo with 3.5 NM of torque and => 2400 RPM
05:56 PM CaptHindsight[m]: an·glo·phone, an glo, to glow and phone for talk, so it means a glowing phone or a phone that glows
05:56 PM JT-Shop: lol
05:56 PM CaptHindsight[m]: I took a few years of Latin so trust me :)
05:58 PM JT-Shop: well anglo mean Anglia the latin name for england
05:58 PM XXCoder: https://youtu.be/Hw7EyItV0Ys nice
05:58 PM XXCoder: gonna get xthx working again so we have preview title name so on
05:59 PM JT-Shop: dare I look without checking usage???
05:59 PM XXCoder: its just 2 minute video of guy making layout on gear
05:59 PM XXCoder: cool tools, thats why i linked to it
06:00 PM JT-Shop: I'll watch after banning this spammer
06:02 PM XXCoder: clickspring guy
06:02 PM CaptHindsight[m]: Latin is one of those languages not named after the people that spoke it
06:02 PM XXCoder: unfortunately stil just making shorts. still havent really made full videos yet
06:02 PM CaptHindsight[m]: then again there was Roman Latin and rural Latin
06:03 PM JT-Shop: weird the spammer shows up as a user but not in the user list
06:08 PM XXCoder: someone pm you a message?
06:08 PM XXCoder: if you has spam issue here, i suggest set accept messages from registered only
06:09 PM XXCoder: it makes spamming mirginally harder
06:09 PM JT-Shop: on the forum
06:10 PM XXCoder: ahh cool
06:11 PM skunkworks: I wonder if most people don't see the issues with amt encoders because they use crappy closed loop drives with very poor responce..
06:11 PM JT-Shop: I think there are 3 moderators including me that watch for spammers and delete the messages and ban them
06:12 PM skunkworks: response?
06:13 PM * skunkworks should figure out how to add spell check to Irssi
06:14 PM XXCoder: linux is interesting. hexchat has spellcheck on it, but not windows version of it.
06:15 PM XXCoder: i dont know why windows dont supply universal languages spell check
06:16 PM _unreal_: XXCoder, I'm using win10 with hex and it has spell check
06:16 PM _unreal_: by default?
06:19 PM * JT-Shop wanders inside for the night
06:20 PM CaptHindsight[m]: has someone bridged freenode with Libera yet just for fun? Can't we all just get along?
06:45 PM Tom_L: JT-Shop, will the pocket routine cut an L shape?
06:45 PM Tom_L: CaptHindsight[m], what fun would that be?
07:03 PM skunkworks: this is the new club...
07:03 PM skunkworks: ;)
07:05 PM Tom_L: the roudy kids
07:06 PM robotustra: hey
07:07 PM robotustra: I mean good evening
07:07 PM * Tom_L gives skunkworks a secret decoder ring
07:08 PM Tom_L: hi robotustra
07:08 PM robotustra: Tom_L, how is it?
07:10 PM robotustra: Tom_L, any interesting projects?
07:14 PM robotustra: I came to some cam functions
07:23 PM robotustra: https://i.imgur.com/kiUDXjf.jpg
07:27 PM andypugh: XXCoder: Ah, no, “Anglophone” is just a word, in the contect that I am interested in. There might be a book called that, but that has nothing to do with my query.
07:28 PM XXCoder: ahh ok lol
07:28 PM Tom_L: robotustra, what's it for?
07:28 PM andypugh: “Anglograph” would mean someone who can _write_ in English. But I can’t think of a word for reading in english.
07:29 PM XXCoder: yeah sometimes its one sided like that
07:31 PM robotustra: Tom_L, I'm writing mini text cad to do simple cad/cam operations and to use it for robot vision in the future
08:12 PM Tom_L: robotustra, no not been doing alot
08:13 PM Tom_L: did redo a setup for a small part
08:14 PM robotustra: is your mill working?
08:15 PM Tom_L: yeah, i did some tuning on the spindle vfd and it's working alot better now
08:16 PM robotustra: nice, I have suspended the lathe for now, need to design electronics and think about lathe control
08:17 PM robotustra: and also go from atmega32u4 to stm32 for contorl
08:17 PM Tom_L: no lcnc?
08:18 PM robotustra: I want it to be "manual" first of all, and the next stage is to connect some controller
08:19 PM robotustra: sometimes it's faster to do manual turns than to write a programmfor lathe
08:19 PM Tom_L: you need jog wheels and cnc it
08:19 PM Tom_L: i use the mill manually sometimes
08:19 PM robotustra: I'll do jog stuff for manual
08:20 PM robotustra: the idea is to use encoders as a manual wheels
08:20 PM Tom_L: you can get mpg pretty cheap
08:21 PM robotustra: I got some encoders already, need to write the code for them, and for spindle too
08:22 PM Tom_L: for avr?
08:22 PM robotustra: yes
08:22 PM robotustra: and for stm
08:22 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/avr/atmega328/PCINT0/quadrature/
08:22 PM robotustra: atmega cannot handle 200khz output
08:23 PM Tom_L: https://www.ebay.com/itm/234026610689?hash=item367d12b001:g:4F4AAOSwV0Jgr0dc
08:23 PM Tom_L: i got one similar to that
08:23 PM robotustra: yeah I used something similar
08:24 PM robotustra: I already showed it inhere I'msure
08:25 PM robotustra: atmega is good enough for XZ feeds, but not fast enough for spindle motor
08:25 PM robotustra: stm32 is fast enough to drive dir/step of spindle motor
08:26 PM robotustra: I'm planning to write my cad 2 more month and then come back to hardware
08:31 PM robotustra: I need at least 125kHz pulses from controller
08:36 PM robotustra: хаха
08:37 PM robotustra: причем это чуваки из мексики
08:37 PM robotustra: заебок
08:37 PM robotustra: что они еще умеют делать кроме как растить таву
08:40 PM robotustra: в прошлом году было 150 выращивателей травы в кали
08:41 PM robotustra: в этом году аж 500
08:41 PM Tom_L: dude
08:41 PM Tom_L: are you in the wrong channel?
08:41 PM robotustra: sorry
08:42 PM robotustra: yeah, wrong channel, getting old :)
08:42 PM Tom_L: growin weed?
08:43 PM robotustra: yes, in cali
08:44 PM robotustra: got the biggest place with weed
08:44 PM robotustra: this year the number of illegal places is 500 and last year it was only 150
08:44 PM robotustra: in cali only
08:45 PM Tom_L: so i was reading
08:45 PM robotustra: you know russian or goole translate it?
08:45 PM Tom_L: google
08:46 PM Tom_L: i had a friend that learned russian and took a trip to visit it once
08:47 PM robotustra: russian is hard to study
08:48 PM Tom_L: i guess he did ok at it
08:48 PM Tom_L: but yeah he said it wasn't easy
08:48 PM robotustra: I would study two more languages, but I don't know which ones and what for :)
08:49 PM Tom_L: i knew another guy that was fluent in 6 languages
08:49 PM Tom_L: not sure what languages
08:50 PM robotustra: I think to study german is ok, just because they are building robots
08:51 PM robotustra: chinise - has too many dialects, spoken chinise has no sense for study it
08:51 PM robotustra: japanese? - who uses it?
08:52 PM robotustra: arabic? also don't know the area of application
08:52 PM Tom_L: chinese
08:53 PM Tom_L: then you can read all these data sheets
08:53 PM robotustra: do they even produce chips?
08:53 PM robotustra: I mean not tsmc
08:54 PM robotustra: they all forced to write datasheets in english because tsmc does 50% of world export of chips
08:55 PM robotustra: from this point of view there is no reason to study chinise.
08:58 PM robotustra: I was even thinking about africaans becaue it sounds fun
09:01 PM robotustra: https://www.youtube.com/watch?v=HcXNPI-IPPM&t=71s
09:27 PM CaptHindsight[m]: robotustra: DIE ANTWOORD is why I don't visit South Africa
09:27 PM CaptHindsight[m]: too silly
09:29 PM robotustra: CaptHindsight[m], who is silly? DIE ANTWOORD or South Africa?
09:32 PM * cloudevil_ thinks of the track XP€N$IV $H1T.
