#linuxcnc Calendar

01:45 AM Loetmichel: mornin'
01:51 AM Loetmichel: hehe, just went thru our metal storage. looks empty... well, sending the boss to the local metal dealer... 3 1m by 2m sheets AlMg3 1,5mm, 1 sheet in 2.0mm, 2.5mm, 3.0mm each, about 12 m of 30 30 03mm angle Alu profile, a sheet or two of 1mm Brass MS63 in 1mm.. THAT will be expensive... :-)
01:56 AM -!- #linuxcnc mode set to +v by ChanServ
02:16 AM splud: like everyone on IRC, I'm here for something tangentially related to the channel, hoping someone might clue me in.
02:18 AM splud: I just got a "3018" hobby cnc mill. it originally had grbl 0.9 on it and exhibited this issue, but I've updated the controller to grbl1.1h, and it continues to have the issue. Actually, 2 issues.
02:19 AM splud: first issue - the serial port seems to dissappear periodically, and when linux re-enumerates it, it's of course on a different tty. if I copy the gcode to a microSD, I can successfully run to completion using the "offline" interface.
02:21 AM Loetmichel: splud: sounds like either your cable/connectors are bad or there is a power supply issue
02:24 AM splud: It uses a miniusb connector on the controller side. I need to fish another cable up to check - I did use different USB connections on the host, to no avail.
02:27 AM splud: Since I can run to completion from the offline controller, I switched to that for my tests. However, when scoring my pattern (which I've done on a smoothie based CO2 Laser cutter many times), it retracts the spindle a few times, moves, applies the cutter and continues on, Except one (an I've examined the code and find no issue), where it just drags across the workpiece without lifting the spindle, and carries on the the next part of the pattern.
02:28 AM splud: same command (and value) is used at the various other points where it retracts, moves, applies, and continues cutting.
02:29 AM splud: And it;s been particular about choking at a particular spot.
02:33 AM Deejay: moin
02:57 AM rmu: splud: this usb issue could be bad connection, micro usb ports are known to wear out mechanically. could also be a noise or grounding issue.
03:20 AM sensille: not the best result for a first try: https://i.imgur.com/PvfMTiu.jpg
03:35 AM rmu: ouch
04:10 AM splud: mlu - this is brand new.
04:10 AM splud: it's also mini USB
04:18 AM rmu: sorry, i meant mini usb.
05:01 AM Loetmichel: hmm... making a sled for the table saw: better using rectangular glide pieces in the slots or T-nut formed ones?
05:01 AM Loetmichel: whats better?
05:07 AM JT-Cave: morning
05:10 AM rmu: Loetmichel: think about if you need to lift the sled
05:11 AM Loetmichel: rmu: that was the question: do i need to?
05:14 AM rmu: if you need, the t-nut is clearly the wrong option ;)
05:14 AM rmu: if you don't know if you need to, you should go do some requ eng aka play bs bingo ;)
05:17 AM Loetmichel: the point was: do i need to lift the sled or do i want the sled to be not able to lift? iE: is it better to have it fixed to the table in case of something goes sideways or is being able to lift it at any place useful enough to live with the added danger?
05:32 AM splud: t-nut can be handy when you have larger pieces being cut, because the sled remains in some sense of registration even when not fully on the top of the table.
06:23 AM Tom_L: morning
07:05 AM Loetmichel: splud: now i am a bit torn what i do
07:05 AM Loetmichel: already made some delrin rectangular bars... should i make some as a "t-nut". too?
07:10 AM splud: you can drill three or four recesses into the bottom to screw a washer into
07:11 AM splud: drill the recess at the diameter of the washer (=the width of the T)
07:11 AM splud: install them, or don't.
07:12 AM Loetmichel: good idea
08:44 AM robotustra: what is the best practice for end stop switches for cnc? NC or NO?
08:45 AM roycroft: if the switch fails it doesn't necessarily matter if it's no or nc - either type could fail either way
08:46 AM Loetmichel: robotustra: NC.
08:46 AM roycroft: but if the wiring fails a nc switch will open and shut down the machine
08:46 AM Loetmichel: No is a risk of not noticing briken wires
08:46 AM Loetmichel: broken
08:46 AM roycroft: whereas a no swith will not notice
08:46 AM Loetmichel: indeed, roycroft
08:46 AM roycroft: i think we have consensus here :)
08:47 AM robotustra: ok, so I'll do NC
08:54 AM roycroft: there is no way to completely safeguard the limit swtich circuit
08:55 AM roycroft: with nc switches it's still possible to abrade the wires and cause a short
08:55 AM roycroft: but the most likely failure is wires coming loose
08:55 AM Loetmichel: but its good practice to do the things that come at no cost
08:55 AM Centurion-Dan2 is now known as Centurion_Dan
08:55 AM roycroft: and i think you'll find that almost all limit switch circuits use nc switches
08:56 AM Loetmichel: also if you have a low resitance pullup the chance of EMI triggering your limit swtiches is TONS lower than with NO ones
08:56 AM Loetmichel: if you have a constant current/short on the wire its easier to not have EMI to influence the inputs as an open circuit that just has a few 100 ohms/kohms pullup
08:58 AM rmu: a cable developing a short is unlikely, but does happen, esp. if its a cable that is moved in some sort of cable drag chain
08:59 AM rmu: i have a bunch of cables where single copper strains managed to come out of the cable. looks kind of funny, but is hard to find/debug
08:59 AM rmu: s/strains/strands
09:02 AM roycroft: it's best to try to protect the cables so that they cannot be cut/abraded
09:03 AM roycroft: and if you do so, then a connection coming loose is by far the most common point of failure
09:03 AM rmu: think of a cable that has to make a U-turn that is constantly moving back and forth and not properly strain relieved, i.e. it is under tension. then, with time, copper strands will migrate out through the insulation
09:04 AM robotustra: my cables will not do U-turn, they will be attached to the table more-less firmly
09:04 AM rmu: i have seen circuits that used a NC and NO switch and get triggered by either... but usually that is overkill
09:08 AM rmu: just wanted to say that moving cables should not be under tension
09:08 AM rmu: or twisted
09:15 AM roycroft: indeed
09:15 AM robotustra: but may be I'll move it by hands
09:15 AM roycroft: and don't use solid copper wires in moving cables
09:17 AM robotustra: it's selbstellung
09:23 AM rmu: selbstellung? sounds german
09:36 AM robotustra: yes it's short variant of "it's self understending"
09:37 AM robotustra: "it goes without saying"
09:37 AM rmu: self understanding? you mean "it" has become conscious? AI revolution?
09:38 AM robotustra: selbstverständlich
09:38 AM robotustra: I misspelled
09:39 AM rmu: ok, that i understand ;)
09:39 AM rmu: nevermind
09:39 AM Loetmichel: self explanatory comes to mind
09:39 AM Loetmichel: the german word for that would be "selbsterklärend" though
09:40 AM robotustra: "it" - it's a word joker which can replace a complex subject previously described in a context
09:40 AM Loetmichel: "selbstverständlich" means more like "of course" in english
09:40 AM Loetmichel: or "mandatory"
09:40 AM robotustra: Loetmichel, how to translate "selbstellung"?
09:41 AM Loetmichel: thats a word that i never herart
09:41 AM Loetmichel: heard
09:41 AM rmu: selbstellung isn't a word, at least not a german one
09:41 AM Loetmichel: indeed
09:41 AM robotustra: I heared it but I may be I write it incorrectly
09:42 AM robotustra: my german is poor
09:42 AM Loetmichel: in which context?
09:42 AM Loetmichel: so we can guess what the correct word would be ;)
09:42 AM robotustra: I wanted to say "it's self understending"
09:43 AM robotustra: self explanatory
09:46 AM Loetmichel: that would be "selbsterklärend"
09:47 AM rmu: robotustra: it's not so obvious as you think (the tension / twist thing), this happened in a commercial CNC machine built 25 years ago by a respected italian manufacturer (that is still around)
09:47 AM roycroft: selbstverständlisch is how i learned it
09:47 AM roycroft: i'm sure there's some nuance there that i don't understand
09:48 AM roycroft: and i'm not arguing with a native german speaker
09:48 AM roycroft: just saying what i was taught
09:49 AM rmu: robotustra: selbstverständlisch is how it is pronounced in parts of germany where they have poor control of "sch" sounds... but it is correctly spelled "selbstverständlich"
09:49 AM roycroft: one of my german teachers was austrian, and the other a northerner (from hannover), and i do recall they spoke quite differently and used different idioms
09:49 AM roycroft: rmu: i probably learned that pronunciation from the austrian
09:49 AM roycroft: certainly not the hannoverian
09:50 AM rmu: roycroft: in most of austria we are talking a kind or bairisch, which is it's own language really, quite different from alemannian (switzerland) and plattdeutsch
09:50 AM roycroft: yes
09:50 AM Loetmichel: roycroft: "selbstverständlich" does NOT mean "self explanatory", it means "that goes without saying" or "mandatory"
09:50 AM roycroft: and there's the nuance that i did not know :)
09:50 AM rmu: selbstverständlich means "of course", "naturally" or "self-evident"
09:51 AM Loetmichel: roycroft: the hannover one would speak pretty much pure "high german"
09:51 AM roycroft: yes
09:51 AM rmu: i would not say mandatory
09:51 AM roycroft: very crisp vowels
09:51 AM Loetmichel: (while "stolpern über spritzen stein" :-)
09:51 AM Loetmichel: -r
09:51 AM roycroft: and no dropping or softening of consonants
09:52 AM roycroft: in hannover one would say "ich muß nach hause gehen"
09:52 AM roycroft: in bayern/switzerland that's more like "i mua na hoa"
09:53 AM rmu: even within the bairisch sub-family, there are different localisations where you won't understand somebody speaking in dialect if you grew up 50km away
09:53 AM roycroft: the austrian teacher would pronounce "ich" as "isch" 100% of the time
09:54 AM robotustra: I like "i mua na hoa" more :)
09:54 AM rmu: "i muass hoam"
09:54 AM rmu: hehe
09:56 AM roycroft: my influence was more from the hannoverian than the austrian
09:56 AM roycroft: when i was in germany natives would occasionally mistake me for someone from the north
09:57 AM roycroft: sadly, my german speaking ability is mostly lost now, having not used it regularly in decades
09:57 AM roycroft: and i always struggled somewhat with vocabulary
09:58 AM roycroft: but apparently i'm very good at picking up pronunciation - every language i've studied i've been told i pronounce very close to natively
09:59 AM rmu: skills that are not used regularly tend to get garbage collected out of working memory
09:59 AM rmu: roycroft: have you tried korean or chinese?
10:00 AM roycroft: i've not
10:01 AM roycroft: formally i've studied german, spanish, classical latin, new testament greek, french, modern hebrew, italian, and dutch
10:01 AM roycroft: informally gaelic and old english
10:01 AM rmu: pfuh that's alot
10:01 AM roycroft: i'm old
10:01 AM rmu: a lot
10:02 AM roycroft: and i was planning on being a language major in college
10:02 AM roycroft: i used to be fairly fluent in german and dutch, and semi-fluent in spanish
10:02 AM rmu: i learned english and french in school and know enough of latin to get half the latin jokes in asterix, and a bit of italian
10:02 AM roycroft: the other languages i'd say were at the level of advanced dabbling
10:03 AM roycroft: fortunately i studied latin while in high school
10:03 AM roycroft: which made spanish, french, and italian a lot easier
10:04 AM rmu: i don't speak any slavic languages, which is a shame, given our neighbouring countries, but it wasn't offered in school back then
10:04 AM rmu: at that time, the world ended at our "eastern" borders
10:06 AM robotustra: roycroft> i'm old - did you see dynosaurs
10:12 AM roycroft: i remember when the first dinosaurs started appearing
10:13 AM * roycroft "dabbled" in russian just enough to learn the alphabet and to be able to pronounce russian words semi-correctly
10:15 AM roycroft: regarding chinese/korean, i suspect i'd be able to pronounce them decently, but i'm well aware that inflection is a critical part of pronunciation, moreso than most other languages
10:15 AM roycroft: i'm not planning on tackling any new languages at this stage of my life though
10:16 AM roycroft: so i'll never know if i'm able to pronounce those languages decently
10:16 AM rmu: i know there are some phonemes in chinese and korean that i can't reproduce, don't even hear them properly i suspect.
10:27 AM roycroft: i'm ready to do the final milling of my workbench components, but one of the leg boards has a wonky edge, with some small bark inclusions
10:27 AM roycroft: i was really stretching the materials
10:27 AM roycroft: i may want to effect a patch to that edge before i do the final milling
10:27 AM roycroft: it would barely be visible, but i'd know it's there
10:27 AM roycroft: and it would probably bug me
10:28 AM roycroft: the epoxy i poured yesterday needs 72 hours to fully cure, so i could do this repair right now and it would be ready for machining by the time the epoxy has cured
10:30 AM robotustra: yeah, russian words mainly spelled according to alphabet pronounciation
10:32 AM robotustra: but you have to know what cyllable is stressed
10:44 AM roycroft: i'm pretty good at figuring that out, robotustra
10:45 AM Rab: Wow...I placed an order with McMaster-Carr at 5pm yesterday, ground shipping. FedEx just dropped it off at 10:36am. Two packages, one from GA and one from IL. $15.99 shipping seemed a little extravagant...
11:02 AM roycroft: i just repaired that leg, and i'm so happy i did
11:02 AM roycroft: it's going to look a lot better
11:03 AM roycroft: and only took a few minues
11:03 AM roycroft: minutes
11:03 AM JT-Cave: McMaster usually ships next day air
11:05 AM roycroft: they ship ground here
11:05 AM roycroft: and most shipments come from reno, which is 2 days ground
11:05 AM roycroft: they've been taking 2-3 days lately
11:07 AM JT-Cave: I've even got packages shipped from a west coast warehouse from McMaster the next day
11:11 AM roycroft: they must like you
11:11 AM roycroft: i've found their customer service second to none
11:11 AM roycroft: my only "complaint" about them is that they ship too quickly
11:11 AM JT-Cave: yea, want to return something just send it back
11:12 AM roycroft: more than once i've placed an order, realised i either got something wrong or forgot something, called them 3 minutes after placing the order, only to be told it had already shipped
11:12 AM * JT-Cave heads back out to the shop to try and finish that damn fence project
11:12 AM JT-Cave: that's quick
11:12 AM roycroft: i'm not sure it's in the box with the label on it that fast
11:12 AM roycroft: but the packing list and picking list has been generated by then
11:13 AM roycroft: i suspect they adopted this model to compete with grainger, who, while a lot slower on processing orders, used to have warehouses all over the country where one could pick things up the same day
11:14 AM roycroft: mcmaster's answer would have been to ship instantly
11:15 AM Rab: FedEx physically picked up from IL 1:20 after order placed.
11:16 AM roycroft: fedex probably park a trailer at the mcmcaster warehouse and swap it out every time it's full
11:17 AM Rab: Grainger still has a lot of warehouses, but I'm usually disappointed by their stock. To be fair, I'm also looking for more esoteric stuff that's probably not worth keeping at every location.
11:18 AM roycroft: they've closed a lot of them, including the one in eugene
11:18 AM Rab: But their catalog is terrible, and the in-store experience is worse. It seems to be tailored by and for a good-old-boy demographic that can't deal with computer search, or even, like, part numbers.
11:18 AM roycroft: ironically, since they closed the local warehouse, they *finally* permit me to buy from them
11:19 AM roycroft: they refused for years
11:19 AM roycroft: i sent them my business registration, but they demanded a sales tax exemption certificate from the state
11:19 AM roycroft: and we have no sales tax in oregon
11:19 AM roycroft: thus, no certificate is possible
11:20 AM roycroft: so they refused to sell to me
11:20 AM roycroft: but i was finally able to get an account set up after they closed the local warehouse
11:20 AM roycroft: it's hard to find stuff on their website though, and their prices are astronically high
11:20 AM roycroft: astronomically
11:21 AM roycroft: so i stick with mcmaster, who have one of the best websites in the universe, and very good pricing
11:21 AM roycroft: the local fastenall folks are snobs/bigots
11:21 AM Rab: Many times I've gone in with a list of Grainger SKUs, ready to go, and the bro dude pulls out the PAPER CATALOG and insists on trying to find the item based on a verbal description instead of just plugging the SKU in to his computer!
11:21 AM roycroft: i've visited them very few times
11:22 AM roycroft: but when i need metric fasteners they cop an attitude about how "american" should be good enough
11:22 AM roycroft: i try to avoid places that have attitudes like that
11:22 AM Rab: roycroft, I think it's a requirement that every local US industrial supply is staffed by snobs and bigots, ideally with a huge chip on their shoulder.
11:23 AM roycroft: fortunately we have eugene fastener, a locally-owned company who stock much of what i use
11:23 AM roycroft: unfortunately they are slow to process special orders, and often have fairly large minimum order quantities
11:24 AM roycroft: so i use mcmaster for anything that would be "unusual" for eugene fastener
11:24 AM roycroft: the other great thing about mcmaster is that they have 2d and 3d cad files for almost everything they carry, as well as pdfs
11:24 AM Rab: The only way I can explain the Grainger in-store experience is that their typical customer just wants a category of thing, like a safety vest or air fittings, and just wants whatever's in stock, so their process is oriented toward that need.
11:25 AM roycroft: it's so easy to go there and download a drawing instead of drawing from scratch
11:25 AM roycroft: rab: grainger seem to be panic-oriented
11:25 AM roycroft: "i need this RIGHT NOW or the world will come to an end"
11:25 AM roycroft: and when you're in a panic you take what you can get
11:25 AM Rab: roycroft, yeah, I ingest the PDFs into Inkscape for mechanical drawings.
11:26 AM roycroft: and you also get to pay 3x as much as you should
11:26 AM Rab: roycroft, I have certainly been in that situation, sometimes far from home, and was glad for Grainger.
11:26 AM roycroft: because in a panic you don't care about price
11:26 AM roycroft: i'm not saying there's anything wrong with that model
11:26 AM roycroft: just that it seems to be grainger's model
11:27 AM roycroft: of course, closing the local warehouse does not fit that model very well
11:27 AM roycroft: if i want something from them i have to order it online and wait a few days for it to arrive
11:27 AM roycroft: but i still get to pay 3x as much as it should cost for the privilege of getting average at best service
11:29 AM roycroft: well, time to head down to the town where i used to work
11:29 AM roycroft: i have some field work to do today
01:32 PM jymmmm: HOLA
01:33 PM Tom_L: ПРИВЕТ
01:38 PM Deejay: GRÜETZI
01:38 PM jymmmm: こんにちは
01:46 PM JT-Cave: j94h8ht
01:53 PM jymmmm: lol
01:54 PM jymmmm: JT-Cave: How's the Chicken Mansion coming along?
01:59 PM unterhaus: amazon has life straw personal water filters as their deal of the day
01:59 PM unterhaus: I recall there were fake versions of that
02:00 PM jymmmm: unterhaus: Eh, I like Sawyer
02:00 PM jymmmm: unterhaus: Also, a 2L soda bottle folds flat pretty well too
02:00 PM jymmmm: ...with no pinholes
02:02 PM unterhaus: sawyer looks nice. I just ordered one of the lifestraws though
02:03 PM unterhaus: thinking about doing some bikepacking
02:08 PM jymmmm: unterhaus: Get a Sawyer Micro https://www.youtube.com/watch?v=1gmvEoL5K_4
02:09 PM jymmmm: unterhaus: I have the mini, but I plan on getting a micro.
02:10 PM jymmmm: unterhaus: The reason I DONT life the lifestraw is you have to have a source of water to filter from, you can't connect any hoses or bottles to it while you are on the move.
02:11 PM jymmmm: unterhaus: and it you get this, you don't have to carry the backflush syrngine https://www.amazon.com/gp/product/B018NJC1A6/r
02:15 PM jymmmm: unterhaus: And comes with a straw too... https://www.amazon.com/Sawyer-Products-SP2129-Squeeze-Filtration/dp/B07HBMC32Y
02:21 PM jymmmm: unterhaus: Hmmmm, maybe I wont get the micro afterall... https://www.youtube.com/watch?v=yDMTtO-4Vco
02:48 PM jymmmm: Good article on Diagnosing Ford Misfires... https://www.motor.com/magazinepdfs/072011_09.pdf
03:09 PM Deejay: gn8
03:13 PM roycroft: my scabbed on piece of wood on the wonky bench leg is going to work out brilliantly
03:13 PM roycroft: the grain and color matches nicely - it will barely be visible if you look at it closely
03:13 PM roycroft: and since it will be on a leg, facing inward, at the bottom of a giant bench it will be completely invisible to anyone but perhaps my cat
03:14 PM roycroft: who i promise does not care
03:20 PM jymmmm: till he starts using it as a scrathing post
03:29 PM roycroft: yes, that is what her interest will be
03:29 PM roycroft: is the wood nice and scratchy
03:30 PM jymmmm: wrap the legs in barbed wire
03:31 PM roycroft: she doesn't go into the shop unsupervised
03:31 PM roycroft: so it's not really an issue
03:33 PM unterhaus: jymmmm the katadyn befree thing he recommends is $70
03:35 PM jymmmm: unterhaus: The "Be Free"? Ouch
03:36 PM unterhaus: everybody seems to love it though
03:36 PM jymmmm: unterhaus: Most backpackers are gram wiennies,, but I think the sawyer sqeeze is probably the best overall, even if it is a bit bigger
03:37 PM jymmmm: unterhaus: You cna use it solo, or connect to your camelpack inline
03:38 PM jymmmm: When I bought my mini, the micro wasn't available, and I wanted something on hand. but I think I'd go for the squeeze in a next purchase, or maybe the gravity one
03:40 PM unterhaus: I am not sure it will hook up to my hydration pack
03:41 PM jymmmm: which?
03:41 PM unterhaus: osprey
03:42 PM jymmmm: why not?
03:42 PM unterhaus: what would I do to clean the hydration pack bladder once I filled it with crummy water? Tablets?
03:42 PM jymmmm: YOu kinda wouldn't, just use it as a drty bag
03:44 PM unterhaus: Of course, in Pennsylvania, there are lots of clear springs. Wish there was a map of them
03:44 PM jymmmm: ther eis this https://www.amazon.com/Sawyer-Products-Inline-Hydration-Adapter/dp/B008JX0QP4
03:44 PM jymmmm: and this https://www.amazon.com/Sawyer-Products-Adapters-Hydration-Packs/dp/B00EURFBKI/
03:47 PM unterhaus: probably best to fill it with clean water then
03:47 PM unterhaus: just go through the top
03:51 PM jymmmm: so with those quick connects, you can backflush
03:51 PM jymmmm: unterhaus: Just FYI, the sawyer micro is suppose to be better than the mini
03:54 PM unterhaus: if it takes a week to get it to go to low flow, that would probably be okay
03:55 PM unterhaus: that wasn't real clear in that video
03:55 PM jymmmm: unterhaus: Do you mind the weight?
03:57 PM unterhaus: how much is it? Full size didnt seem that much bigger
03:57 PM unterhaus: I think I worry about size more than weight
03:59 PM jymmmm: https://www.rei.com/product/103050/sawyer-squeeze-water-filter-system
03:59 PM jymmmm: and that kit has the adapters I believe
04:00 PM jymmmm: Under $30 at walmart... https://www.walmart.com/ip/Sawyer-Products-SP129-Squeeze-Water-Filtration-System-w-Two-Pouches/24689330
04:01 PM unterhaus: interestingly a number of bad reviews at rei
04:03 PM jymmmm: hydratin pack version... https://www.amazon.com/Sawyer-Products-SP131-PointOne-Squeeze/dp/B00WG9AFW6/
04:04 PM jymmmm: unterhaus: Yeah, the sawyer bags suck
04:05 PM unterhaus: I might get the befree
04:06 PM jymmmm: Cool, if you do, let me know how it works for you. Be sure to watch cleaning videos before hand
04:08 PM splud: Camelbak is a local company, right here in Podunk, California.
04:09 PM jymmmm: unterhaus: $40 for the 20oz https://www.rei.com/product/100537/katadyn-befree-collapsible-water-filter-bottle-20-fl-oz
04:10 PM jymmmm: splud: is that right next to BFE?
04:10 PM jymmmm: unterhaus: the 3L is $70 https://www.rei.com/product/139666/katadyn-gravity-befree-water-filtration-system-3-liters
04:16 PM unterhaus: not a big fan of camelback. They sued osprey because their fill cap was the same size as theirs. I mean, c'mon man
04:16 PM splud: jymmmm - actually, it is a community touching the north end of the San Francisco bay
04:17 PM jymmmm: unterhaus: eeeesh
04:17 PM unterhaus: the redesigned osprey bladder is nicer though
04:17 PM splud: IIRC, it was a bite valve
04:18 PM unterhaus: huh, that doesn't seem to have changed at all
04:19 PM unterhaus: well, except maybe it was the useless and infuriating on/off function?
04:19 PM splud: The suit was settled confidentially.
04:19 PM splud: I.e. one party may have agreed to license...
04:20 PM unterhaus: I was happy to notice you can't inadvertently make it so no water comes out of the valve
04:20 PM unterhaus: no water comes out if you don't bite on it so...
04:21 PM unterhaus: the old one if you twisted the valve, it was shut off
04:25 PM unterhaus: how many years of soap fit in this under-counter tank https://www.instructables.com/id/High-Capacity-Easy-Use-Soap-Dispenser-Tank/
04:29 PM unterhaus: or you can use some 5/16" polyethelene tubing and run it into a gallon bottle of soap
05:51 PM veegee_: What in the hell....
05:51 PM veegee_: I just got a quote for 1m of schedule 40 brass pipe for $500
05:51 PM veegee_: 1"
05:51 PM veegee_ is now known as veegee
05:51 PM veegee: I really hope they made a typo and added an extra digit
05:54 PM roycroft: 1m of schedule 40 c320 should be around $100
05:54 PM roycroft: US$100
05:54 PM roycroft: so maybe CDN$500 :)
05:55 PM roycroft: or AUD$1500
05:55 PM roycroft: plus $1500 shipping to australia
05:55 PM roycroft: plus $1500 in duty and vat
05:56 PM Tom_L: if it made it past the crackhead shippers
05:56 PM SpeedEvil: Maybe they hand-whittle it out of bar.
05:56 PM roycroft: it's an artisan extrusion
06:14 PM XXCoder: reports of my death is exaggerated
06:21 PM roycroft: i've not been following the news, so i've not heard such reports
06:21 PM roycroft: but i'm glad they're fake news
06:22 PM XXCoder: yeppers heh
06:22 PM XXCoder: i went hours out into nowhere to do some stargazing
06:28 PM roycroft: idaho?
07:09 PM jymmmm: XXCoder: We can arrange for them not to be
07:09 PM XXCoder: northwest corner of a
07:09 PM XXCoder: wa
07:09 PM jymmmm: XXCoder: Port Angeles?
07:10 PM XXCoder: past it
07:10 PM jymmmm: XXCoder: There's nothing past it, except Canada
07:10 PM XXCoder: i planned to go past neah but that town was closed
07:10 PM XXCoder: not that corner, the other one
07:10 PM jymmmm: You said NW
07:10 PM XXCoder: wa has 2 northwest corners
07:11 PM jymmmm: okey fiiiiiine
07:11 PM jymmmm: XXCoder: Are you in WA now?
07:11 PM XXCoder: yeah never left the state
07:12 PM jymmmm: XXCoder: OH, I thought you were in midwest somewhere
07:12 PM XXCoder: nearly 5 hours drive yeserday, and over 5 hours drive today lol
07:12 PM XXCoder: crazy
07:12 PM jymmmm: XXCoder: 5 hr drive from/to where?
07:13 PM XXCoder: route as shown by google is nearly 4 hours, but real drive time was 5 as region is super hilly
07:13 PM XXCoder: so many curves and slowdowns
07:13 PM jymmmm: XXCoder: 5 hr drive from/to where? And why? JUST stargazing?
07:14 PM XXCoder: pretty much. its hard to get to darkness level 1 skies
07:14 PM XXCoder: though I did many stops to look at very nice seas
07:15 PM jymmmm: XXCoder: starting from where?
07:15 PM XXCoder: tacoma why? wanna recreate my route?
07:15 PM jymmmm: XXCoder: You live in WA?
07:15 PM XXCoder: yes
07:16 PM XXCoder: you really dont need to ping me each time, we are only guys talking
07:16 PM veegee: roycroft did you mean C230? Or did you actually mean C320?
07:16 PM jymmmm: Hmmm, weird, I thought you were in like oaklahoma or something
07:16 PM XXCoder: sign for that state is like "murder" but with handshape of O
07:17 PM XXCoder: they come up with new and less awful sign but whatever
08:10 PM veegee: Whoops, I was wrong about the quote. I requested a quote for 1m, but they somehow took that to mean "144 inches". Damn Canadians, don't even know how to interpret their own units
08:10 PM veegee: So $500 for 3.66m of C230 brass 1" pipe
08:13 PM Tom_L: is there a belt series between GT2 and XL?
08:14 PM XXCoder: thats quite long
08:18 PM robotustra: Tom_L, what do you mean between? what can be in between apples and tomatos?
08:18 PM Tom_L: pitch size
08:19 PM robotustra: gt2 is 2mm pitch?
08:19 PM Tom_L: 2 3 or 5
08:19 PM Tom_L: i've got 3mm pitch
08:19 PM robotustra: trapezoidal profile?
08:19 PM Tom_L: i waned something a bit heavier
08:19 PM robotustra: and xl?
08:19 PM Tom_L: GT it round
08:20 PM Tom_L: xl is trapezodial
08:20 PM robotustra: what pitch xl has?
08:20 PM robotustra: i saw somewhere pitch 8 mm
08:21 PM Tom_L: says 1/5 P
08:21 PM Tom_L: dunno
08:21 PM Tom_L: close to .187" roughly
08:22 PM robotustra: https://www.sdp-si.com/products/details/timing-belt-detail.php
08:22 PM Tom_L: i'm on their page looking
08:22 PM Tom_L: but i was trying to find the ones i've got currently
08:22 PM robotustra: it's around 5 mm
08:23 PM robotustra: 4.52 mm
08:23 PM robotustra: you have pulleys but don't have a belt?
08:24 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/new_pulleys/timing_pulley2.jpg
08:24 PM Tom_L: i have those on it right now
08:24 PM Tom_L: i may need to go with something heavier
08:24 PM robotustra: sorry it's 4.72 mm
08:25 PM robotustra: it looks to me like HDT-3m
08:26 PM robotustra: no?
08:26 PM Tom_L: the 5mm GT might be ok too
08:27 PM robotustra: how did you measure it?
08:27 PM Tom_L: which?
08:27 PM Tom_L: the xl?
08:27 PM robotustra: the pulley
08:27 PM robotustra: no the pulley you have
08:27 PM Tom_L: i have gt2 and xl
08:27 PM Tom_L: i used the xl on the z drive
08:27 PM Tom_L: gt on the spindle
08:27 PM robotustra: ah, you need both?
08:28 PM Tom_L: but due to space i think the xl would be too big for the spindle
08:28 PM robotustra: you are rebuilding something?
08:28 PM Tom_L: may get a heftier spindle motor
08:29 PM Tom_L: i'm just looking to see what i've got on it right now
08:30 PM Tom_L: the 5mm GT might be ok
08:30 PM Tom_L: i can go a bit wider too
08:30 PM Tom_L: the current belt is 9mm wide
08:30 PM Tom_L: the sherline spindle just isn't that big
08:36 PM robotustra: I've read a little bit about timing belts
08:36 PM robotustra: some profiles are silent on big rpms
08:36 PM robotustra: some lauder
08:37 PM robotustra: trapezoidal profiles are more silent
08:37 PM robotustra: than round
08:37 PM Tom_L: don't round have better grip?
08:37 PM Tom_L: more contact
08:37 PM robotustra: but even withing one profile there is a difference in dB for different pitch
08:38 PM robotustra: I also was thinking like this, but not
08:38 PM robotustra: trapezoidal have better grip
08:39 PM robotustra: timing belt in the car is trapezoidal
08:39 PM robotustra: higher tooth does not mean better grip
08:42 PM robotustra: I think I got pdf file from this site where was written all the info about belts
08:46 PM robotustra: including noisiness
08:47 PM robotustra: depending on RPMs
08:48 PM robotustra: Tom_L, https://www.sdp-si.com/PDFS/Technical-Section-Timing.pdf
08:49 PM Tom_L: thanks
08:51 PM robotustra: I think I'll save it for myself too
08:52 PM Tom_L: there's a balance between finding what you need and finding what they stock
08:55 PM robotustra: you can wind what you want and order on ebay, like i did
08:55 PM robotustra: they didn't have right length but china has al variety of lengthes
10:18 PM roycroft: part of that balance is how quickly you need the stuff
10:18 PM roycroft: and the before times are gone, possibly forever
10:19 PM roycroft: so planning ahead whenever possible is more important thn ever
