12:09 AM roycroft: winding sticks and a straight edge are all that i would need
12:13 AM XXCoder: winding sticks?
12:16 AM roycroft: two sticks that are exactly parallel, and contrasting colors on the top
12:17 AM roycroft: set one on one end of the bed
12:17 AM roycroft: and the other on the other end
12:17 AM roycroft: you can sight down the tops of the sticks and be able to see if it's even a tiny bit twisted
12:39 AM CaptHindsight: re
12:46 AM XXCoder: roycroft: interesting looking emup now
12:47 AM XXCoder: this type? https://www.youtube.com/watch?v=ZKAxSouPGtE
01:21 AM roycroft: yes, xxcoder
01:21 AM roycroft: they work remarkably well if they're made well
01:21 AM roycroft: and all that requires is to clamp them together when you plane the tops
02:17 AM XXCoder: roycroft: nice
02:18 AM XXCoder: gloops: saw your short engrave video. wondered what its all about lol
02:20 AM gloops: hi, it wasnt about much really - just testing 10 degree v bits
02:21 AM gloops: i found out they are very sharp when fitting the first one - went straight through my finger lol
02:21 AM XXCoder: ow
02:22 AM XXCoder: ya extremely sharp
02:24 AM gloops: seems to work ok in wood though which i was not sure about
02:24 AM gloops: i.e didnt snap
02:33 AM XXCoder: heh funny story
02:33 AM XXCoder: i was using tiny 1/16 ball endmill carbide
02:34 AM XXCoder: spindle stopped while maching was running
02:34 AM XXCoder: but tool plowed though pine, no break lol
02:45 AM gloops: ive only snapped 1 3mm cutter and that was jogging straight into board with spindle off, i always think be careful with small cutters from experience with metal work, different thing with pine and mdf
03:17 AM XXCoder: should still be careful gloops
03:18 AM XXCoder: just different kind of careful lol
03:18 AM gloops: yes like not trying to push the cutter up in the collet with finger heh
03:18 AM XXCoder: lol yep
03:35 AM gloops: adds another capability though for fine detail, probably too slow for many things, i am interested in molds for low melt point metal now you raised the subject though
03:36 AM XXCoder: ya wish I could find that awesome site again :(
03:37 AM gloops: could also put lettering on small things, wooden jewellery etc
03:38 AM XXCoder: would be interesting to use one of those higher low temp metals as inlay filler
03:38 AM gloops: i watched a few youtube vids, seems you can cast tin in a silicone mold - not a big step from making a wooden model then taking a silicone mold from it
03:38 AM XXCoder: what temperate does tin melt at. i know its pretty low, after all kids made tin solders back then
03:38 AM XXCoder: play break em and recast
03:39 AM gloops: XXCoder yeah, i looked at some wooden ear-rings, they had different bands of wood and some silver metal sandwiched, then machined - looked effective, must have been soft metal and the only way i could see they got the metal in was to pour it into the wood
03:40 AM XXCoder: yea another possibility lol
03:40 AM gloops: tin is quite lower i think 240C or so, can be melted on electric cooker
03:40 AM XXCoder: thats defnitely hotter than low temp allows I found though
03:41 AM gloops: tin/pewter seem easy enough to get hold of
03:41 AM XXCoder: pewter you can grab old pots and such, BUT may have lead
03:41 AM XXCoder: theres few versions of pewter, older tend to have lead
03:41 AM gloops: yeah there is old pewter knocking around
03:42 AM gloops: as you say - probably various mixes
03:42 AM gloops: pewter comes up as slightly lower melt than tin, from 170 degrees
03:44 AM XXCoder: LOL first attempt found it!!
03:44 AM XXCoder: https://www.belmontmetals.com/product-category/low-melting-fusible-alloys/
03:44 AM XXCoder: saved link!
03:44 AM XXCoder: BEND metal: 70c
03:45 AM XXCoder: my 3d printer could melt that metal
03:45 AM XXCoder: CAST metal: 138-170c yep still within 3d printer temperates
03:46 AM XXCoder: theres 47c one. my fart after eating spicy stuff could melt it.
03:46 AM gloops: ive bookmarked it this time - may want to reference in the future
03:46 AM gloops: lol, could melt that with a hairdryer
03:47 AM gloops: although not a good idea for hair clips
03:47 AM XXCoder: so many alloys
03:47 AM XXCoder: SAFE metal. jeez
03:47 AM XXCoder: "This is a Bismuth based non-eutectic alloy which has unique properties of shrinking immediately upon solidification"
03:48 AM XXCoder: "and growing back to zero in 1 hour, followed by additional growth"
03:48 AM XXCoder: wow weird
03:48 AM XXCoder: since its at zero for a hour thats plenty of time for measuring mold accuracy
03:49 AM Wolf__: bizmuth is pretty safe
03:49 AM Wolf__: people are known to drink the stuff
03:49 AM XXCoder: yeah but wow so many alloys and properies
03:49 AM XXCoder: in this case SAFE means different than safe for humans though
03:50 AM gloops: some are similar to solder really, but that is expensive in hardware stores
03:50 AM Wolf__: pepto bismol
03:50 AM Wolf__: made from bismuth
03:53 AM gloops: how is tin for machining ? assuming very soft
03:55 AM gloops: pewter is high brass content, thats uually good for working with
04:05 AM SpeedEvil: Tin is only very slightly harder than lead
04:05 AM SpeedEvil: Softer than aluminium.
04:06 AM XXCoder: is there lower temp alloy as strong as alum?
04:06 AM XXCoder: doubtful but..
04:08 AM gloops: so could probably combine tin/hardwood in the same part and machine together
04:10 AM gloops: tin inlay would probably fall out though if poured into wood, when machining
04:16 AM XXCoder: dunno
04:27 AM jthornton: morning
04:27 AM XXCoder: hey jt
05:24 AM Deejay: moin
06:29 AM Tom_L: morning
06:30 AM XXCoder: morning
06:42 AM jthornton: morning
07:02 AM jdh: https://imgur.com/gallery/El4FvYI
07:03 AM XXCoder: dang
07:04 AM XXCoder: i cant imange the amount of energy it takes
07:04 AM XXCoder: you can see it smoke oil
07:10 AM SpeedEvil: I'd guess a little under 10kW.
07:11 AM SpeedEvil: Assuming a force of ~2500kg.
07:14 AM fragalot: Y'know what. I'm impressed with this little HSB57 closed-loop stepper driver
07:14 AM fragalot: appears to respond smoothly up to 4000rpm
07:15 AM fragalot: currently testing it with a function gen, and it appears to even 'catch up' if I jump from 100kHz to 300kHz drive signal :P
08:28 AM ktchk2: How is the debian stretch uspace working??
09:34 AM * fragalot sighs
09:34 AM fragalot: some days you spend 4 hours trying to get a dumb PWM output enabled, only to find out the only reason it's not working is because winders locked your .elf file and the bastard hasn't actually updated since god knows when
09:35 AM fragalot: yet atollic studio casually jogs along pretending everything is fine
09:37 AM hazzy-m: ktchk2: Been using it for almost a year here, very happy with it
09:42 AM gloops: i made a mitre sled this morning, works perfect, i did catch a decent cross cut blade on a bolt during the trials though lol
09:44 AM Tom_L: pics
09:45 AM gloops: what now? lol, i closed up a couple of hours ago
09:45 AM Tom_L: but you just now brought it up here!
09:47 AM gloops: well i saw other people seemed to be having a bad day, my day was mixed, sled works fine, £80 blade down
09:47 AM gloops: https://www.youtube.com/watch?v=zbTVWjoXuG4
09:48 AM gloops: its only something like that, i cut the bits on the cnc - perfect 90 degrees, a lot easier than try to get that by hand
09:53 AM fragalot: gloops: nothing is perfect, have you done a 15-cut test yet? :P
09:54 AM gloops: not tried the 15 cut test, what is that? by perfect i mean i cant see anything wrong with it with no reading glasses on
09:54 AM Tom_L: therein lies the problem...
09:59 AM fragalot: gloops: the 5 cut test is where you cut a board 5 times, flipping it 90° each time, so the error stacks up
10:02 AM gloops: ahh yes, done something similar, i dont really try to claim any superior skill or anything, when i was setting this gantry for square i did it by tapping the home switch on one side along a slot then checking, did it one time and it must have landed bang on, every test ive tried i cant find it isnt cutting square
10:32 AM gloops: this wont last long https://twitter.com/i/status/1089197312428204033
10:46 AM fragalot: I'm not sure they've taken the potholes into account here
10:52 AM gregcnc: the robot abuse video comes to mind
11:28 AM Loetmichel: gnhihi, wife just prepares a traditional german winter dish for tomorros: "Grünkohl mit Kassler und Mettenden"... her recipe is a bit heavy on the meats though... she put in 1kg of Kale, 1 kg of diced potatoes, 1.5kg of smoked pork chop, 1.2kg of streaky bellies and 16 ground pork sausages... THAT will last quite a few days for 2 persons. At least its a dish that gets better with each "reheat"
11:28 AM Loetmichel: ;)
11:29 AM MarcelineVQ: do you prefer kale over cabbage?
11:29 AM Loetmichel: THAT dish calls for Kale
11:29 AM Loetmichel: germans do have quite a few cabbage dishes
11:30 AM MarcelineVQ: kale just seemed like an odd choice for a dish you'd want to reheat but I guess there's many types of kale
11:32 AM Loetmichel: MarcelineVQ: https://www.lecker.de/gruenkohl-eintopf-mit-mettenden-17704.html <- basically that recipe plus a lot of smoked pork loin and smoked pork belly
11:34 AM gregcnc: that looks good
11:34 AM gregcnc: my personal favorite https://www.kwestiasmaku.com/przepis/bigos-z-kiszonej-kapusty
11:39 AM MarcelineVQ: we'd cut the meat smaller here but that does look good :>
11:40 AM MarcelineVQ: not for eating consideration, just that you can get more sear on slices
11:45 AM Loetmichel: gregcnc: that looks tasty, too ;)
02:11 PM CaptHindsight: https://3dprint.com/234479/desktop-metal-raises-438-million-total-with-additional-160-million-round-what-does-it-mean/
02:12 PM CaptHindsight: desktop metal sintering
02:13 PM CaptHindsight: metal powder + wax binder + polymer, extruded like FDM...
02:13 PM zq: wew lad
02:13 PM CaptHindsight: then sintered
02:14 PM zq: how does the rigidity of a sintered part compare to equivalent cnc-ed one?
02:14 PM CaptHindsight: so the finished parts are still porous and not as dense as cast or machined
02:15 PM CaptHindsight: it's similar to https://en.wikipedia.org/wiki/Metal_injection_molding but not as dense since there is no compaction stage in the process
02:15 PM Loetmichel: GNHIHI... i just watched SVSeeker video... Doug: "I like that knipex tool, i am just wary of spending much money on tools on a boat because you WILL hear that 'GABLUNK' eventually!" ... right he is. ;)
02:16 PM CaptHindsight: https://www.epma.com/metal-injection-moulding
02:17 PM CaptHindsight: how important is powdered metal parts that can be made in an office vs industrial site?
02:17 PM CaptHindsight: office fab = powdered and porous
02:18 PM CaptHindsight: I think investors are buying into hype yet again
02:20 PM fragalot: Loetmichel: I have about 9 of those pliers. They are well worth the "gablunk" :P
02:20 PM Loetmichel: fragalot: i am born in the city where knipex has its main factory
02:21 PM fragalot: CaptHindsight: it's only nice for R&D purposes in engineering bureau's that have no manufacturing capabilities... (eg. it's use is limited)
02:21 PM Loetmichel: dont say bad things about german tools! ;)
02:21 PM fragalot: they're pricey but so damn worth it
02:21 PM Loetmichel: ... and wera. And belzer. And gedore... :-)
02:21 PM fragalot: paid themselves back in the reduction of knuckle plasters alone :D
02:21 PM fragalot: not Wiha?
02:21 PM Loetmichel: i can imagine
02:22 PM CaptHindsight: do Germans still make better tools?
02:22 PM Loetmichel: wiha too ;)
02:22 PM fragalot: CaptHindsight: if it comes down to pliers. Hell yes they are vastly superior
02:22 PM Loetmichel: Remscheid is the german tool city
02:22 PM fragalot: I don't know of any other brand that even comes close to knipex
02:22 PM CaptHindsight: when i was a kid all we had to say was it is made in Germany to get something
02:22 PM Loetmichel: like Solingen (right next to Remscheid) is known for blades of all kinds
02:23 PM fragalot: Loetmichel: used to be known for great steel, now it's known for having had great steel. :P
02:23 PM Loetmichel: i worked in those tool factories quite a bit
02:23 PM CaptHindsight: is Solingen still full of knife shops?
02:23 PM Loetmichel: yes
02:23 PM Loetmichel: and knife factorys
02:23 PM Loetmichel: actually my sister still lives in solingen
02:24 PM CaptHindsight: is she a knife maker?
02:24 PM Loetmichel: nope. she is a hairdresser master... that now works as an IT admin for a 200 PC company ;)
02:24 PM CaptHindsight: SpeedEvil brought up diamond infused copper blades yesterday
02:25 PM CaptHindsight: copper/bronze
02:25 PM fragalot: for abrasion?
02:25 PM Loetmichel: cant see the use case for that?
02:25 PM CaptHindsight: antimicrobial and hard
02:26 PM CaptHindsight: also a gimmick like the ginzu knives
02:26 PM CaptHindsight: also has high heat transfer, so heat spreader applications
02:28 PM fragalot: https://i.imgur.com/zgrg81L.jpg
02:28 PM CaptHindsight: sorry to hear about the autobahn speed limits
02:29 PM fragalot: as if you can go above 80kmph these days on there anymore anyway with all of the road works
02:29 PM CaptHindsight: is it that bad now?
02:29 PM fragalot: was last time I went to northern germany
02:30 PM CaptHindsight: fragalot: how are your roads doing?
02:30 PM fragalot: what roads? :D
02:30 PM CaptHindsight: i recall them more for scenery
02:30 PM fragalot: the belgian road authorities are finally playing catch-up on backlogged maintenance
02:31 PM CaptHindsight: here some states are better than others but the infrastructure in general is falling apart from age and neglect
02:32 PM fragalot: well we've got quite a few viaducts & tunnels that are literally falling apart
02:32 PM fragalot: but it's fine because they've put up some netting in the worst areas.
02:32 PM CaptHindsight: reminds me of cold war films on trains and bridges
02:32 PM CaptHindsight: yeah nets catch stuff
02:32 PM CaptHindsight: i expect to see more nets here
02:32 PM fragalot: the problem with the netting is that it's attached to the thing it's supposed to catch
02:33 PM CaptHindsight: nothing is perfect
02:34 PM CaptHindsight: I expect more of this https://www.youtube.com/watch?v=C31IlOHNzbM
02:34 PM CaptHindsight: Bridge Collapse Minnesota
02:35 PM CaptHindsight: https://youtu.be/PTtBN34AXl0?t=9
02:36 PM fragalot: CaptHindsight: https://www.youtube.com/watch?v=VInjN4msFeE
02:38 PM CaptHindsight: more of a calzone
02:38 PM fragalot: props for creativity though
02:39 PM CaptHindsight: pizza in China is one thing I avoid
02:40 PM CaptHindsight: baked goods in general, I'd see the same items day after day, the exact same items
02:40 PM fragalot: even if it's handmade office food?
02:41 PM CaptHindsight: whats the average temp of offices in the west?
02:41 PM CaptHindsight: several years ago I was working on SLA printers for the Chinese market...
02:42 PM CaptHindsight: they said office environment for the specs
02:42 PM fragalot: 22°C
02:42 PM CaptHindsight: in China it varies from -20C to 45C
02:43 PM CaptHindsight: they are unheated in the far north
02:43 PM fragalot: 15°C if you work at facebook, 25°C if your boss read an article somewhere that said employee productivity peaks at this temperature
02:44 PM CaptHindsight: nothing like using an unheated bathroom at -10C
02:44 PM fragalot: wait
02:45 PM fragalot: you had a bathroom in china?
02:45 PM CaptHindsight: so whats the average man on the street in EU think about Brexit?
02:45 PM CaptHindsight: well what they refer to as bathrooms
02:45 PM fragalot: the only consensus is that they're sick of it
02:46 PM fragalot: otherwise it fully depends on what their preference for news media is
02:46 PM CaptHindsight: sounds right
02:46 PM CaptHindsight: fragalot: how often are you in the US?
02:47 PM fragalot: used to be 3 times a year, but haven't been since the big T
02:47 PM CaptHindsight: has Murdoch taken over any news in the EU?
02:48 PM CaptHindsight: Sky Italia
02:48 PM fragalot: no idea
02:49 PM CaptHindsight: big T?
02:49 PM fragalot: Trump
02:50 PM CaptHindsight: child emperor
02:50 PM fragalot: hey, he's single handedly ensured that his current employees will get paid for at least 3 weeks.
02:51 PM CaptHindsight: it's pathetic
02:51 PM CaptHindsight: we still have a gook chunk of old men here that are just like him
02:52 PM CaptHindsight: people keep falling for the crap
02:52 PM fragalot: that's because vaccines cause autism on this flat earth
02:53 PM CaptHindsight: yeah thats it
02:53 PM fragalot: (no seriously)
02:53 PM CaptHindsight: hehe
02:53 PM fragalot: because of our insane medical care
02:53 PM fragalot: people that are too dumb for their own good, and wouldn't have made it past the birth canal 100 years ago
02:54 PM fragalot: are suddenly able to reproduce, and reach hundreds if not thousands of likeminded bafoons
02:54 PM CaptHindsight: do you see faster way of making sand or investment molds than laser/DLP curing photopolymer coated sand in a bed?
02:54 PM fragalot: we've reached the point where evolution no longer decides which genes should propagate
02:55 PM fragalot: the only other option I know of is inkjet based bed technology
02:55 PM CaptHindsight: inkjet is slower
02:55 PM fragalot: then that makes my answer "no, I do not". :)
02:55 PM CaptHindsight: you can spread a layer of paste faster than jetting
02:56 PM CaptHindsight: then you only cure the paste that is the mold
02:56 PM CaptHindsight: and you can reuse the uncured paste
02:57 PM CaptHindsight: the downside is the particle size of the sand
02:58 PM CaptHindsight: and you can't cast metals in an office
02:58 PM CaptHindsight: well you could but the smoke alarms would probably go off
03:00 PM CaptHindsight: fragalot: I don't think unchecked capitalism is sustainable, thats why they are moving to something authoritarian
03:00 PM CaptHindsight: you clean out the middle class and then you need to suppress any rebellion
03:00 PM fragalot: agreed
03:01 PM CaptHindsight: it worked for thousands of years but now tech has changed things
03:02 PM fragalot: thre was no such thing as unchecked capitalism until the industrial revolution
03:02 PM SpeedEvil is now known as Guest93627
03:02 PM fragalot: there was only a fine balance of how many people could be sustained in a certain area
03:02 PM CaptHindsight: China is a good example, they are cracking down on subversion but the party has no chance if the masses rebel
03:04 PM CaptHindsight: the average Chinese has seen a vast improvement in their quality of life for the past 3-4 decades
03:04 PM CaptHindsight: now it has stalled
03:05 PM CaptHindsight: if things go south the average Wang then there will be problems for the party
03:05 PM fragalot: which is why you make sure the new generation can't build up enough funds to know that something is wrong
03:05 PM fragalot: :-)
03:06 PM fragalot: start 'm out with a good bit of debt owed to private companies
03:06 PM CaptHindsight: it's a little different in the US
03:06 PM CaptHindsight: yeah worked here for the past couple decades
03:07 PM CaptHindsight: the student loan trap
03:08 PM CaptHindsight: are public universities still free or low cost there
03:08 PM CaptHindsight: ?
03:08 PM fragalot: depends on where you mean
03:08 PM fragalot: in the UK tuition tripled from 3k to 9k GBP a few years back
03:08 PM fragalot: here it's around €600 a year
03:08 PM CaptHindsight: kids here were going to Germany for near free tuition
03:09 PM CaptHindsight: wow thats still far lower than here
03:09 PM fragalot: yup
03:09 PM fragalot: wait until you hear what it costs to get your tooth pulled here
03:09 PM CaptHindsight: lets seee, here it's $1k per
03:10 PM fragalot: €6.
03:10 PM fragalot: the rest is covered by manadatory health insurance
03:10 PM CaptHindsight: 30 years ago it cost me $500 at a oral surgeon for a wisdom tooth
03:10 PM fragalot: which is €80 per year.
03:10 PM CaptHindsight: yeah, they have quite a racket going here
03:11 PM fragalot: yeah
03:11 PM fragalot: I'm also baffled by how medieval dentists seem to be still in the US
03:11 PM fragalot: with the nitrous oxide & all that
03:11 PM CaptHindsight: people don't understand how inexpensive is to make meds and medical devices
03:11 PM fragalot: or whatever it is that those kids on youtube are on :P
03:13 PM CaptHindsight: they have done a pretty good job of making people here fall for status symbols
03:13 PM CaptHindsight: phones, clothing, cars, medical care
03:13 PM fragalot: how is medical care a status symbol
03:14 PM CaptHindsight: because you can afford a high end plan
03:14 PM CaptHindsight: the low end state provided plans don't provide the same care
03:14 PM fragalot: I think the only difference between the plans here is whether or not your insurance covers injuries abroad
03:15 PM fragalot: (and we've all got EHIC cards which cover europe)
03:15 PM CaptHindsight: they don't let you bleed out but you don't get the follow ups a high plan provides
03:15 PM CaptHindsight: you get whatever prevents a possible lawsuit
03:16 PM fragalot: the real issue is
03:16 PM fragalot: what can you do about it now
03:16 PM CaptHindsight: most people here still think it's just not possible to have a single payer system in the USA
03:16 PM fragalot: now that it's managed to get this bad.. how do you come back from that
03:17 PM CaptHindsight: they did such a good job of breaking it
03:17 PM CaptHindsight: no short term quick fix
03:17 PM CaptHindsight: i think it will take 20-30 years
03:17 PM fragalot: workers rights too - i've heard stories of people getting fired because they got sick for 2 days, or their car wouldn't start after a heavy snow storm
03:17 PM CaptHindsight: you have to get rid of the old entitled white mindset
03:18 PM CaptHindsight: they have slowly corrupted the oversight
03:18 PM CaptHindsight: food, worker rights, etc
03:18 PM fragalot: https://i.imgur.com/2M7WxRl.mp4 <- so satisfying.
03:18 PM CaptHindsight: cost too much to change out a food additive, lobby to change the law
03:19 PM gregcnc: https://www.instagram.com/daichihira/
03:19 PM CaptHindsight: and if you downsize the oversight ...
03:20 PM CaptHindsight: fragalot: they have convinces a large part of the population that what has been working in Europe just can't work in the USA
03:20 PM CaptHindsight: convinces/convinced
03:21 PM fragalot: well, with the current people in charge of things, and with the people that keep voting them in.. it can't.
03:21 PM CaptHindsight: it's going to take a generation
03:21 PM gregcnc: people seem to balk at 40% taxes
03:21 PM CaptHindsight: kids under 30 here have been screwed over and they know it
03:22 PM gregcnc: social security will get ugly
03:22 PM fragalot: gregcnc: I pay more taxes than that, but get a LOT back from that..
03:22 PM CaptHindsight: as they organize and gain power it could change
03:22 PM gregcnc: is health insurance a thing there?
03:22 PM CaptHindsight: but I expect all sorts of manufactured crisis to be roadblocks for them
03:23 PM fragalot: gregcnc: it is. at a mindboggling €80 per year.
03:23 PM CaptHindsight: yeah but if you need surgery you have to wait 6 months :)
03:23 PM fragalot: depends on how urgent the surgery is :P
03:23 PM CaptHindsight: what they don't say here is if it's an emergency you get it right away
03:24 PM CaptHindsight: but if you can olny hold one thought in your head at any moment you can't understand
03:26 PM CaptHindsight: smart people here in their 20's pretty much all say that they are just waiting for the old men to die off
03:27 PM fragalot: what about their offspring that's taking up their place?
03:27 PM CaptHindsight: their gender fluid offspring?
03:27 PM gloops: old people have been more conservative forever lol
03:28 PM fragalot: hey look! there's one right there!
03:28 PM * fragalot runs
03:28 PM CaptHindsight: they just don't care as much about race, sexual preference, invisible angry man in the sky
03:28 PM fragalot: ;)
03:29 PM gloops: what im saying is, those young voters will think differently when they grow up
03:29 PM CaptHindsight: gloops: yeah i get it
03:29 PM gloops: all this lgbt stuff is a passing fad
03:29 PM CaptHindsight: hah
03:30 PM fragalot: sure, it will pass because at some point people will finally stop caring
03:30 PM CaptHindsight: it's difficult to accept by those raised to have a bias against it
03:31 PM gloops: im not anti by the way, but i believe it is being promoted by influential powers as part of a political agenda
03:31 PM CaptHindsight: it only matters to the sky man worshippers
03:32 PM gloops: if you educate kids from the age of 5 on these matters yes you will see an increase in the stats
03:32 PM CaptHindsight: when i say that I just don't care and never have .....
03:33 PM CaptHindsight: people still misunderstand
03:33 PM gloops: “If a man is not a socialist by the time he is 20, he has no heart. If he is not a conservative by the time he is 40, he has no brain.” Winston Churchill
03:33 PM CaptHindsight: I just never thought it was an issue
03:33 PM CaptHindsight: wow, who hasn't heard that before?
03:33 PM fragalot: CaptHindsight: but if you're not religious, then what stops you from raping people?
03:33 PM fragalot: checkmate.
03:34 PM CaptHindsight: hah
03:34 PM CaptHindsight: if the fear of any angry invisible man is the reason then you are lost
03:35 PM CaptHindsight: fragalot: yeah dumb people can't get passed that one
03:35 PM CaptHindsight: scare kids, hope it sticks for life
03:35 PM gloops: not believing in God does not necessarily mean you have to revert to cavorting lust and depravity
03:36 PM fragalot: gloops: yeah but it means you have no reason NOT to.
03:36 PM CaptHindsight: gloops: but lots of dumb people think that it's so
03:36 PM gregcnc: society
03:36 PM CaptHindsight: they can't see the big picture
03:36 PM gloops: there are other ideals and virtues
03:36 PM CaptHindsight: they have been trained to think they are special and the angry man in the sky will punish them for disobeying him
03:37 PM CaptHindsight: not even dumb
03:37 PM gloops: it works?
03:37 PM gregcnc: that was the old way, not so much anymore
03:37 PM CaptHindsight: just ignorant or very impressioned from an early age
03:38 PM CaptHindsight: fear and guilt control lots of people
03:38 PM gregcnc: and some have none at all
03:39 PM CaptHindsight: well religion has to go to be replaced by how what you do effects others
03:39 PM gloops: reptilian brain
03:39 PM gloops: cant stand the pressure - fear > anger > rage
03:40 PM CaptHindsight: Churchill was another child man
03:40 PM CaptHindsight: try that perspective when you read over his history
03:42 PM CaptHindsight: people are still falling for socio and psychopaths and allowing them to lead
03:42 PM gloops: most of humans problems throughout history are based on resources, making commodities and the distribution of them
03:42 PM gloops: the machines will soon liberate us from that struggle!
03:43 PM gloops: we will all be philosophers in our happy idleness
03:43 PM gregcnc: uh well
03:43 PM CaptHindsight: I bet you liked show and tell as a kid
03:44 PM gloops: i liked war films as a kid
03:45 PM CaptHindsight: what is interesting is how many people now fit somewhere on the autism scale
03:45 PM gloops: they should eat more fresh vegetables
03:47 PM gregcnc: so many kids with issues these days
03:47 PM gloops: and so many more issues
03:47 PM Tom_L: building lots of cncs today i see
03:47 PM gregcnc: eh, I made parts today
03:47 PM gregcnc: I should be writing second op programs
03:48 PM gloops: im going to be back on cnc a lot more soon, been too busy with other stuff but the end is in sight
03:49 PM fragalot: CaptHindsight: when they first put helmets on soldiers, the number of complaints about head injuries skyrocketed too
03:50 PM fragalot: obviously helmets are bad
03:50 PM CaptHindsight: fragalot: it blocked the rays from the sky gods
03:50 PM gregcnc: do all screw type compressors have oil injection?
03:50 PM CaptHindsight: obviously
03:50 PM fragalot: gregcnc: I believe so
03:51 PM gregcnc: why, automotive superchargers don't
03:51 PM CaptHindsight: the old men are complaining again
03:51 PM gregcnc: and why do automotive scroll compressors have oil, and air compressors don't?
03:52 PM CaptHindsight: no oil, mine does
03:52 PM CaptHindsight: for the crank
03:52 PM gloops: not seen a turbo without oil
03:52 PM gloops: the bearings would melt in seconds
03:52 PM CaptHindsight: bong type air compressor?
03:53 PM gregcnc: gloops not asking about turbo
03:53 PM CaptHindsight: well I'mma goinaa bring em up anyways
03:53 PM CaptHindsight: sorry
03:53 PM gloops: 200 000 rpm
03:54 PM gregcnc: i wonder how hard it would be to make an air compressor from an auto A/C scroll type
03:54 PM gregcnc: gloops isn't it past your bed time?
03:54 PM gloops: no ive got hours left, had a sleep this afternoon
03:55 PM CaptHindsight: do people find it difficult to build or operate machines why having discussions about knitting, cat pics or the price of coffee in the sothern hemisphere?
03:55 PM CaptHindsight: why/while
03:55 PM gloops: i brought turbos up as auto compressors were mentioned
03:56 PM gregcnc: specific types were mentioned
03:56 PM Tom_L: CaptHindsight, i find it amusing the topics we cover here on slow days
03:56 PM CaptHindsight: i think that is the point
03:59 PM gloops: CaptHindsight that is a view held by many debating societies or 'think tanks' the best ideas often emerge during mixed conversations rather than a strict focus on a single subject, the brain works that way, flicking from one thing to another, making connections, obviously the rules here are nothing to do with me, im quite happy to stick to linuxcnc or related stuff
04:00 PM CaptHindsight: OT police
04:03 PM gregcnc: ebay: 0 Results for Kress, so we searched for dress. Thanks a lot
04:03 PM CaptHindsight: anything cute?
04:05 PM gloops: the stasi will never accept that old chestnut when they check your history gregcnc lol
04:05 PM CaptHindsight: gregcnc: same results here
04:05 PM gregcnc: search results are getting worse, google too
04:06 PM CaptHindsight: https://www.kress-robotik.com/en/
04:06 PM CaptHindsight: gregcnc: I keep a browser for my tech searches handy that I don't clear the history on
04:07 PM CaptHindsight: it makes a difference
04:07 PM gregcnc: i was looking in toys for specific items, but why they think I want a dress
04:07 PM CaptHindsight: a fresh cookie, history and IP address slows down my tech searches
04:08 PM CaptHindsight: so it goes both ways
04:08 PM gregcnc: there were time google just didn't return garbage when looking for technical topics where you might get a few hits
04:09 PM gregcnc: fuck me, but I'm signed in to google when i search
04:09 PM CaptHindsight: for me using my phone to search is worst
04:09 PM CaptHindsight: near useless
04:09 PM CaptHindsight: mostly sponsored results
04:10 PM gregcnc: hah yeah and the ads that come up
04:13 PM CaptHindsight: haven't tried using a linux tablet with a LTE modem yet
04:14 PM CaptHindsight: Linux tablet to control what goes in and out of the modem
04:15 PM CaptHindsight: and then LTE with my wireless provider using their DNS vs VPN
04:15 PM CaptHindsight: should be interesting
04:16 PM CaptHindsight: Comcast business and a wifi hotspot on the tower near me...
04:16 PM CaptHindsight: but you have to log in with your account number
04:16 PM CaptHindsight: and a/has a
04:16 PM gregcnc: for comcast wifi
04:17 PM CaptHindsight: yeah for business service
04:27 PM gloops: seem to be fewer diy beginners joining here for advice, i wonder if that coincides with few downloads of linuxcnc, or more to do with freenode registration
04:28 PM gregcnc: I think newer people are more likely to use the forum
04:28 PM gregcnc: I regularly see new Linuxcnc builds on instagram
04:29 PM gloops: i dont know, when i first joined there seem to be a steady trickle of newbs asking how to wire breakout boards up or fix limit switches stuff like that - not now
04:30 PM gloops: still people on facebook installing linuxcnc, a lot more using arduino though
04:33 PM pcw_home: Most tech questions seem to be on the forum
04:35 PM hazzy-m: when loading a userspace comp with `loadusr -W` I keep getting "Waiting for component 'halintf' to become ready....................................." even though the comp shows as ready in halshow
04:35 PM hazzy-m: the component works as expected when run directaly with halrun from a terminal
04:35 PM hazzy-m: any ideas?
04:40 PM Deejay: gn8
04:43 PM russian_troll: hazzy-m: Today's Log http://www.isaeff.net/logs/%23linuxcnc/2019-01-27.html
04:44 PM hazzy-m: LOL, so many logs
04:46 PM XXCoder: hazzy-m: only one actually
04:46 PM XXCoder: russia troll is blank pages
04:46 PM hazzy-m: yeah, just noticed, strange
04:46 PM hazzy-m: there are only two then :)
04:46 PM hazzy-m: logs
04:46 PM logs: hazzy-m: today's log: http://irc-logs.kcjengr.com/linuxcnc/2019/01/26.html
04:46 PM XXCoder: lol
04:48 PM hazzy-m: my server was sleeping on the job, just had to give it a good talking to
04:50 PM CaptHindsight: Linuxcnc has matured
04:51 PM CaptHindsight: most questions are searchable on the forums
04:51 PM CaptHindsight: unfortunately many people don't put in the effort to move away from winders
04:52 PM CaptHindsight: even the Chinese CNC's feature Mach vs LCNC
04:53 PM CaptHindsight: when I was in China there was an influence to write Chinese CNC applications
04:53 PM CaptHindsight: i think it was mainly due to the lack of Linux familiarity there
04:54 PM CaptHindsight: most had $2 winders ISO's on their computers
04:54 PM CaptHindsight: they only saw it as $2 vs free
04:56 PM CaptHindsight: https://www.automationtechnologiesinc.com/products-page/vectric-software/
04:56 PM CaptHindsight: https://www.automationtechnologiesinc.com/products-page/centroid-acorn-cnc-controller-kit-software/
04:56 PM CaptHindsight: or mach3/4 on his site
04:56 PM CaptHindsight: he sells the licenses and gets a %
04:57 PM CaptHindsight: I've asked him about LCNC and only get a blank stare
04:57 PM XXCoder: vcarve isnt that free? or was that different one with same name
04:57 PM XXCoder: not surpised no money inn lcnc
04:58 PM CaptHindsight: but he was almost jumping up and down about carrying the 3d printers and giving back a few $ to the designers
04:58 PM CaptHindsight: Vcarve pro $689
04:58 PM CaptHindsight: and so lesser version for $144
04:59 PM CaptHindsight: so/some
04:59 PM CaptHindsight: looks like 7-8 different versions with different prices

05:14 PM BitEvil: CaptHindsight: On the aforementioned topic of diamond infused knives.
05:14 PM BitEvil: https://phys.org/news/2019-01-nanotechnology-enables-weld-previously-un-weldable.html
05:14 PM BitEvil is now known as SpeedEvil
05:15 PM SpeedEvil: Now, engineers at the UCLA Samueli School of Engineering have developed a way to weld the alloy, known as AA 7075. The solution: infusing titanium carbide nanoparticles—particles so small that they're measured in units equal to one billionth of a meter—into AA 7075 welding wires, which are used as the filler material between the pieces being joined. A paper describing the advance was published in
05:15 PM SpeedEvil: https://www.nature.com/articles/s41467-018-07989-y
05:15 PM CaptHindsight: neat
05:17 PM SpeedEvil: http://sci-hub.tw/https://www.nature.com/articles/s41467-018-07989-y 1.7% by volume of 40-60nm TiC
05:17 PM SpeedEvil: I would be truly astounded if this couldn't be extended to some other alloys that fail in similar manner.
05:18 PM CaptHindsight: have there been any recent patents aps for TiC rod?
05:18 PM SpeedEvil: Oooh
05:18 PM SpeedEvil: https://www.alibaba.com/product-detail/Titanium-Carbide-TiC-Nanopowder-Nanoparticles-TiC_50041759063.html
05:19 PM SpeedEvil: $20-60/kg
05:20 PM CaptHindsight: a plasma setup to make particles isn't that complicated
05:20 PM CaptHindsight: was just thinking about making one the other day
05:20 PM CaptHindsight: but thats already cheap from China
05:20 PM SpeedEvil: CaptHindsight: Well, yes. And that might be a reasonable route if you can't cheaply buy it off the shelf for $0 (rounded) per kilo of prodct
05:21 PM CaptHindsight: i was thinking about copper
05:21 PM CaptHindsight: no copper oxide
05:21 PM SpeedEvil: ah
05:22 PM CaptHindsight: packaged in Nitrogen or stabilized in a solvent
05:23 PM CaptHindsight: https://xingluchemical.en.alibaba.com/product/60670146300-804858357/Nano_copper_powder_price.html
05:25 PM SpeedEvil: Oh. For the above diamond/copper I was just thinking molten infiltration
05:26 PM SpeedEvil: The nature paper says basically 'we melted aluminium, and flux and powder, and it just works' - then they extruded it.
05:26 PM SpeedEvil: (to get the rods)
05:27 PM CaptHindsight: yeah, I was thinking about printed vs plated PCB's
05:28 PM SpeedEvil: ah
05:30 PM CaptHindsight: the rods seem easy to make
05:31 PM SpeedEvil: yeah. Molten aluminium + powder + blendtek
05:31 PM CaptHindsight: " This method and introduced mechanisms provide an innovative pathway to fabricate filler wires which enable arc welding for other hard to weld material systems and have the potential to improve welding of dissimilar materials."
05:31 PM SpeedEvil: CaptHindsight: It doesn't really stop there.
05:32 PM SpeedEvil: As it could be quite inexpensive if you put it at the beginning of your average rolling mill/...
05:32 PM XXCoder: theres pcb services that you can get 10 for $5
05:32 PM SpeedEvil: Or casting.
05:32 PM XXCoder: within certain complex level plus size i guess
05:32 PM SpeedEvil: For metals that have problems with grain size on welding.
05:33 PM SpeedEvil: grain growth in the base metal leading to cracks
05:34 PM XXCoder: CaptHindsight: is that breakout board or what
05:34 PM XXCoder: also wow so many inputs and some outs
05:36 PM SpeedEvil: Hmm. Diamond nanopowder is unfortunately 'expensive' at $10/g.
05:38 PM CaptHindsight: XXCoder: the goal is to print boards faster and cheaper than plating
05:39 PM XXCoder: just directly deposting metal traces eh
05:39 PM CaptHindsight: has to be copper
05:40 PM SpeedEvil: Silver works too, and a few other metals.
05:40 PM CaptHindsight: yes, but the cost is too high
05:40 PM XXCoder: how about abusing the inkjet system?
05:40 PM SpeedEvil: Silver is $15/oz or so. At 1 oz/sqft, that is not prohibitive.
05:41 PM XXCoder: just lay copper powder alloy, then burn it into copper traces
05:41 PM CaptHindsight: XXCoder: we have already been doing it for years but
05:41 PM CaptHindsight: raw materials and patents have been the issues
05:42 PM SpeedEvil: Patents are annoying.
05:42 PM SpeedEvil: Some are legit, 99.99% are not.
05:42 PM XXCoder: yet something worthy to have otherwise people wont bother to invent
05:42 PM XXCoder: but yeah rounded recangle, apple inc
05:42 PM XXCoder: THAT is one of unworthy ones.
05:42 PM CaptHindsight: system works as planned
05:42 PM XXCoder: did you know theres hundreds thousands of patents on phones?
05:43 PM SpeedEvil: XXCoder: Sure. But inventions need to be actually hard - on the level of 100* the total effort it would take an average engineer to do a full patent search for an invention.
05:43 PM SpeedEvil: XXCoder: Or rather not 100* - but average patents in a product *
05:43 PM XXCoder: cull useless patents out and its easier to search
05:43 PM SpeedEvil: Or it's not a patent on a technology, it's a tax on engineers developing stuff as normal.
05:43 PM CaptHindsight: it's designed to keep YOU from playing
05:44 PM gloops: misread that as 'cull useless patients' lol
05:44 PM XXCoder: capt what should happen is inventor has exclusive rights for while, then everyone can join in the fun
05:44 PM XXCoder: but it doesnt
05:44 PM CaptHindsight: ayes, the system has been hijacked
05:44 PM XXCoder: lol gloop
05:45 PM SpeedEvil: See also copyright 'for a limited period'.
05:45 PM XXCoder: mickey mouse finally expired
05:45 PM XXCoder: this year is first time usa has copy expirations for 20 years
05:45 PM XXCoder: https://www.theguardian.com/books/2019/jan/02/the-drought-is-over-mass-us-copyright-expiry-brings-flood-of-works-into-public-domain
05:46 PM XXCoder: 1922 is now public
05:46 PM SpeedEvil: There is an argument for >15 years. There is no reasonable argument for life+70.
05:46 PM CaptHindsight: XXCoder: https://www.nano-di.com/
05:46 PM XXCoder: SpeedEvil: what I would set is lifetime or 25 years, whichever is longest
05:46 PM SpeedEvil: Your average young authors work if published in 1922 would not now expire till 240
05:47 PM XXCoder: no more than that
05:47 PM SpeedEvil: 2040
05:47 PM gloops: i dont know, an inventor might only make one thing in his lifetime that generates any income
05:48 PM XXCoder: ie: if published, then die 10 years later, then it gets 25 years from publish date. if author lives more than 25 years afterwards then it expires anyway
05:48 PM XXCoder: gloops: inventing and creating is different invention patent lives maybe 7 years depend on counyru
05:48 PM XXCoder: supposely anyway
05:48 PM CaptHindsight: XXCoder: get some $ and lobby for this change in congress
05:49 PM XXCoder: hah good luck getting enough money
05:49 PM CaptHindsight: and then get the WTO to follow
05:49 PM gloops: i suppose anyway with the pace of technology now, most inventions are superceded pretty quickly, within a decade or so
05:49 PM XXCoder: gloops: yeah the rationale of 7 years for patents. but companies is cheating on it
05:50 PM XXCoder: so patents is very messy and diffult to figure out.
05:50 PM CaptHindsight: https://www.youtube.com/watch?v=bDIF8N055j0
05:50 PM XXCoder: hell even patent lawyers have problems.
05:50 PM CaptHindsight: XXCoder: Is the camera man sitting on a roller coaster ??
05:51 PM XXCoder: CaptHindsight: was that circuit board printer?
05:51 PM CaptHindsight: motion sickness warning
05:51 PM XXCoder: also, damn bad camerawork, couldnt watch for more than minute
05:51 PM CaptHindsight: yes
05:51 PM CaptHindsight: yeah awful
05:51 PM XXCoder: no shit. im extremely sensive to it when i am even slightly sick, and I am still recovering
05:52 PM XXCoder: damn cameraperson trying to make it extreme cool by fancy camera shooting, and it all ends up looking like home video.
05:54 PM XXCoder: dont they have ever heard of anti-shake tech? oh its too soon, just onvented 15 years ago or so
05:54 PM SpeedEvil: Gimbals are getting nice and inexpensive.
05:55 PM XXCoder: unfortunately more and more people just use phone
05:55 PM XXCoder: which dont exactly have room for those stuff
05:55 PM skunkworks: have 2/3rds of the gantry crane running.. Nice having vfd's running the motors. No more clunk - clunk motion.
05:55 PM SpeedEvil: I mean gimbals you stick the whole phone on.
05:55 PM XXCoder: thats true
05:55 PM XXCoder: that is if people ever remember it exists
05:56 PM SpeedEvil: Then there is always the 'if teh phone wasn't tehre, there would be no video' thing.
05:56 PM skunkworks: Thought I took a video - but I must have just taken a picture.. Duh
05:59 PM CaptHindsight: well the UI on the phones for the phone and camera get worse every update
05:59 PM CaptHindsight: it's like these devs never make phone calls
06:00 PM XXCoder: nor take pics or videos lol
06:00 PM SpeedEvil: I last made a phone call on my phone 10 years ago.
06:00 PM SpeedEvil: (pics and video is a very fair point though)
06:00 PM CaptHindsight: SpeedEvil: do you just teleport these days?
06:01 PM SpeedEvil: My 10yo phone (camera app comes on when you open the physical shutter) is arguably better.
06:01 PM XXCoder: lol once people can teleport there go whole vehicle industry, roads, phones
06:01 PM XXCoder: airplane industry and airports too
06:01 PM CaptHindsight: he might be from the future
06:02 PM CaptHindsight: his telepod might have crashed or malfunctioned stranding him here
06:09 PM CaptHindsight: https://www.youtube.com/watch?v=BKdaBRkz8Vo Laser welding in Super Slow Motion
06:10 PM XXCoder: gonna love how much it looks like water.
06:10 PM XXCoder: or even mecury
06:11 PM XXCoder: man time scale is so brief
06:13 PM SpeedEvil: :)
06:14 PM Tom_itx: do they use filler while laser welding?
06:16 PM SpeedEvil: Tom_itx: some processes do
06:17 PM SpeedEvil: It's more autogenous though in general I think.
06:26 PM andypugh: Taking shape… https://photos.app.goo.gl/gPJNULk3kTRg7Tqi9 One original and two clones in process.
06:27 PM XXCoder: nice
06:27 PM XXCoder: order or for youself?
06:27 PM andypugh: One for myself, one spare to sell or in case of something going wrong.
06:28 PM XXCoder: not bad idea. easier to make 2 same time.
06:28 PM andypugh: Yes, it’s a habit I have got in to. Make 2, or 3, and keep the best one.
06:29 PM CaptHindsight: andypugh: https://forum.linuxcnc.org/statistics
06:29 PM jthornton: what is the offset for on the base?
06:29 PM CaptHindsight: jthornton: you and PCW are tied for 2nd place :)
06:34 PM XXCoder: https://www.youtube.com/watch?v=fsqylnTC64Y
06:34 PM XXCoder: sucky camera warning
06:35 PM XXCoder: he usually dont do handcams thankfully so its just showing stuff at start
06:44 PM XXCoder: so that material type grabs oil and stays wet with it
06:44 PM XXCoder: keeping machine lubicated
06:45 PM XXCoder: i wondered why some parts at work was made with those stock. I know now I guess
06:46 PM Tom_itx: it's rather abrasive isn't it?
06:46 PM XXCoder: not as bad as fiberglass
06:46 PM XXCoder: but yes
06:46 PM Tom_itx: phenolic?
06:47 PM XXCoder: no idea what that word is
06:47 PM Tom_itx: looks like it
06:50 PM XXCoder: interesting
06:51 PM XXCoder: one board, 1/4 inch 12"x24" is 32 bucks absically
06:52 PM XXCoder: 84 bucks for same but half inch
06:55 PM gregcnc: the amount of time he spends on custom tooling is incredible
06:55 PM XXCoder: no crap
06:55 PM XXCoder: im pretty sure he was very very expensive worker, and worth it when he wasnt retired
06:56 PM gregcnc: I don't think he is retired
06:56 PM XXCoder: dunno he talked about going to place he used to work at, maybe just moved on from. dunno
06:59 PM XXCoder: millions of slots each of em have to be "dermeled" ouch
07:00 PM gregcnc: tedium doesn't bother him, that's why he is good at what he does
07:01 PM XXCoder: it does or does not for me, sometimes i just grind away at work and wow shift is done already
07:01 PM XXCoder: but sometimes not
07:01 PM gregcnc: most people would give up at that's close enough
07:02 PM XXCoder: hes sealing those away while working on other aways.
07:02 PM XXCoder: parts*
07:02 PM XXCoder: so it dont have dirt or something
07:12 PM MarcelineVQ: like that circular dovetail cutting pattern at 24:00
07:16 PM hazzy-m: https://www.instagram.com/p/BtHnCTMg0a-/?utm_source=ig_web_copy_link
07:17 PM XXCoder: marc yeah that was interesting
07:18 PM XXCoder: arudinos dunno lol
07:18 PM XXCoder: I want a pendant or in least board controls but dont know hoiw to do it
07:20 PM hazzy-m: I've been using the 8bit ADCs on the 7i76 for reading pot overrides, but they drift very badly, the ones on the arduino seem better so far ...
07:21 PM hazzy-m: would not trust the arduino for anything critical though
07:25 PM skunkworks: hazzy-m: I think andypugh make a smart serial slave out of an arduino...
07:25 PM hazzy-m: oh, that would be nice!
07:26 PM skunkworks: hazzy-m: or a... https://mesaus.com/index.php?route=product/product&path=72&product_id=125
07:30 PM hazzy-m: I was planning to get that, but decided to play with the Arduino and see if it might work well enough
07:30 PM hazzy-m: all I have are three pots to read, nothing critical
08:00 PM gregcnc: holyshit 600kEuro crowdfunded utilty knife https://makerknife.backerkit.com/hosted_preorders
08:01 PM XXCoder: lol fancy
08:01 PM norias: wtf
08:01 PM XXCoder: i dont know if it works well under stress of daily work
08:01 PM norias: hate it
08:01 PM norias: next.
08:01 PM XXCoder: $5 blade! because of dumbass logo on it
08:02 PM XXCoder: im so ordering it lol
08:02 PM norias: i hate any utility knife that isn't fixed blade
08:02 PM XXCoder: i bought 100 for $8 something. used 15 of em in rebuild
08:02 PM gregcnc: just happened to click his YT showing a shop he bought
08:03 PM XXCoder: so many drywall cutting lol
08:03 PM norias: i'm actually really picky about my utility knife
08:03 PM norias: there's one specific model i prefer
08:03 PM norias: of course, i'm a plasterer's son
08:03 PM norias: i grew up with them
08:04 PM Rab: That doesn't look very ergonomic.
08:05 PM XXCoder: Rab: hmm didnt think of that but yea
08:05 PM XXCoder: imange holding that cutting drywall for hours.
08:05 PM XXCoder: them rounded but still sharp corners
08:05 PM Rab: I guess if you want your EDC utility knife to approximate the painful experience of trying to use your EDC Leatherman pliers...
08:06 PM gregcnc: no people just keep it in their pocket to open amazon boxes
08:09 PM gregcnc: I carry one of these https://www.knifecenter.com/item/SOGAC76/SOG-Access-Card-20-Practical-Satin-275-inch-VG10-Steel-Blade
08:10 PM XXCoder: i dont carry a knife. amazon boxes I just open by hand. easy enough.
08:10 PM XXCoder: probably from days I used to break hundreds of boxes a day
08:10 PM SpeedEvil: https://www.aliexpress.com/item/BGT-Small-Pocket-Knife-Camping-EDC-Hunting-Key-Chain-Folding-Knives-Survival-Utility-Tools-Titanium-Handle/32818654395.html for me on a neckchain.
08:10 PM SpeedEvil: On a 'ID retractor'.
08:11 PM SpeedEvil: So handy
08:11 PM XXCoder: for work I have slide out breakable blade
08:11 PM XXCoder: easy enough to use plier break blade and theres fresh part
08:11 PM gregcnc: also some flavor of swisstool
08:12 PM XXCoder: its $1 and its still in use for couple years lol
08:12 PM andypugh: I haven’t even started the Arduino sserial slave, though I do think it’s a good idea. Though I have decided that I will probably use this instead, more CPU higher serial rate: https://www.adafruit.com/product/3800
08:15 PM andypugh: Puzzled by him buying bearings and destrying them, you can buy loose needles: https://simplybearings.co.uk/shop/Loose-Balls-&-Rollers-Loose-Steel-Rollers/c23_5043/index.html
08:16 PM SpeedEvil: ^hah also.
08:16 PM XXCoder: 100 for 12 pound
08:16 PM SpeedEvil: The above knife is pictured before the 'route out liner lock step
08:16 PM XXCoder: dunno where he lives at but maybe price isnt worth it, or maybe shipping isnt possible or too expensive?
08:17 PM SpeedEvil: Or just spending another few minutes to save $2 isn't worth it.
08:17 PM SpeedEvil: He does not seem to be focussed on cost.
08:18 PM andypugh: I am not 100% convinced that he will get a reult better than the original prismatic eays
08:18 PM SpeedEvil: I do hope he posts results.
08:19 PM SpeedEvil: It's an interesting project
08:19 PM XXCoder: indeed
08:19 PM XXCoder: its not something i would use, likely but still interesting, and I learned something about that material
08:20 PM SpeedEvil: I suspect also if you were somewhat more cavalier in your attitude, you could put it in fuzzy, and let the filters catch the fuzz
08:20 PM andypugh: I have hours of footage of my fixed steady manufacture. I probably should publish it, as it’s pretty unusual as CNC horizontal milling.
08:22 PM XXCoder: phenolic i milled those bunch of time but loearned what it is by that video
08:23 PM * norias perks up.
08:23 PM norias: andypugh: horizontal milling?
08:25 PM andypugh: There is a UK brand called “Tufnol” with a bizarre naming scheme. “Carp Brand” “Whale Brand” etc: Carp, Vole, Whale, Crow and then numbers. there must be a fun story there.
08:25 PM XXCoder: is this good deal I wonder https://www.aliexpress.com/item/10mm-thickness-Bakelite-sheet-Phenolic-laminate-300-300-10MM-Phenolic-resin-plate-Insulation-board/1687396738.html
08:25 PM andypugh: norias: Yes, I decided that for the parts i am making the horizontal spindle makes more sense
08:25 PM norias: andypugh: what machine is this?
08:26 PM andypugh: Harrison Universal
08:26 PM norias: googling now
08:26 PM norias: ahh, badass
08:27 PM norias: cnc?
08:27 PM XXCoder: andypugh: upload it. whynnot?
08:28 PM andypugh: norias: Unedited, https://www.youtube.com/watch?v=zwNT5t6lb1I
08:29 PM andypugh: Not originally CNC, I modified it.
08:29 PM norias: very cool
08:29 PM XXCoder: linuxcnc?
08:29 PM andypugh: Of course :-)
08:29 PM XXCoder: nice
08:29 PM XXCoder: ui looks different
08:29 PM norias: i have a soft spot of horizontal spindles
08:30 PM XXCoder: andy I really want encoder wheel and knobs pendant even if machine is small
08:30 PM XXCoder: using keyboard is INSANE
08:30 PM XXCoder: i feel so unsafe using keyboard
08:31 PM andypugh: The UI is “Touchy"
08:31 PM XXCoder: did you see jthornton's work on documing new ui style?
08:31 PM XXCoder: its FAR more customizable
08:32 PM andypugh: Glade (including Gscreen) is very cutsomizable. Except Glade is buggy and PyGTK is unsupported and buggy
08:32 PM XXCoder: its not glade but interesting
08:32 PM XXCoder: lets see if I saved link
08:32 PM andypugh: norias: Horizontals can be so much more rigid.
08:32 PM norias: aye
08:32 PM XXCoder: i'd think so, tools is held on both ends
08:33 PM XXCoder: https://forum.linuxcnc.org/41-guis/35849-qtpyvcp-tutorial andypugh
08:33 PM andypugh: XXCoder: I have been folloeing develipment on the forum
08:33 PM norias: i sorta want to make a hobby cnc that's horizontal
08:33 PM XXCoder: i dont read forums unfortunately lol
08:33 PM norias: like, tormach sized
08:33 PM norias: modern horizontal
08:33 PM XXCoder: wow interesting
08:33 PM norias: hsk spindle, tool changer, etc
08:33 PM andypugh: I moved the steady nearer the drive end for other ops, to make it even stiffer.
08:33 PM XXCoder: there is some stuff horzionals is just best on
08:34 PM andypugh: Though I have concluded that my arbour is bent. Not sure what to do about that.
08:34 PM norias: i've been reading about motor design
08:34 PM norias: so i can design a motorized spindle
08:35 PM norias: or understand what i'm buying if i buy one
08:35 PM norias: i was thinking of doing the spindle as a "government project" at work
08:35 PM norias: i could heat treat and cylindrical grind whatever i need
08:39 PM andypugh: I think that you would need a gearbox for a horizontal spindle. I am running at 100rpm at the moment, and that isn’t even wth a particularly big cutter.
08:41 PM XXCoder: andy cant buy replacement arbour? or use lathe to make one after reverse engineering?
08:42 PM XXCoder: im sure not even remotely compliant to your model mill but https://www.victornet.com/subdepartments/Milling-Machine-Arbors-and-Spacers/430.html
08:42 PM norias: andypugh: why a gearbox?
08:42 PM andypugh: Arbours come up occasionally on eBay, but are quite expensive. I definitely could make one, and have made 1 1/4 and 27mm ones for gear hobs.
08:43 PM andypugh: norias: To get the speed range. My mill runs from 45 to 1000 rpm. You won’t get that with a direct drive, and the 1000 is annoyingly slow.
08:44 PM norias: hmm, yeah, i don't know yet
08:45 PM norias: what is it, though, a 220V single phase induction motor driving your spindle?
08:45 PM XXCoder: is it upgradable?
08:46 PM andypugh: It was originally a 440V three-phase. I had it rewired internally for 24-V three-phase and run it through a VFD for infinitely variable speed. Lowest speed is 1 rpm. (and it’s unstoppable)
08:46 PM andypugh: (240V 3-phase)
08:47 PM norias: ahh, ok
08:48 PM andypugh: Here is an unusual use for the lowest speed, with the VFD wound down, https://www.youtube.com/watch?v=thtDRjgbxRE
08:49 PM XXCoder: nice
09:01 PM andypugh: Night all
