02:09 AM Deejay: moin
02:29 AM miss0r2: !seen diverdude
02:30 AM miss0r2: bah. how does this work again?
03:57 AM Jin|away is now known as Jin^eLD
03:57 AM Jin^eLD: morning
03:57 AM XXCoder: yo
03:58 AM Jin^eLD: installed a dehumidifier in the workshop yesterday, let's see how expensive that turns out to be in the long run
03:59 AM XXCoder: big compressor type?
04:00 AM Jin^eLD: I went for one that can handle tripple the size of my shed which is currently really small - only 15m^2, but I hope to expand at some point, compressor with gas defrost
04:00 AM MarcelineVQ: they're not bad if you have them come on when needed and you're generous with the range they work on
04:01 AM MarcelineVQ: as in, don't expect them to only run once-in-awhile if you're after under 50% humid
04:01 AM Jin^eLD: I almost went for absorber, because my shed is not heated in the winter, but that one would have been too weak for the summer and the temp rarely drops below 5 degrees in the building, so the compressor with gas based defrost had a wider operational range
04:01 AM Jin^eLD: from 5 degrees C
04:01 AM MarcelineVQ: dehumidifier will tend to warm a space
04:01 AM Jin^eLD: it did about 15% reduction yesterday within a little under 2 hours
04:02 AM Jin^eLD: then I switch it to a bit less than half (it was still going) and had to leave
04:02 AM Jin^eLD: so we'll see if it stopped today and what the actual humidity is
04:02 AM Jin^eLD: unfortunately it has no display so you have to use some external barometer for orientation
04:02 AM Jin^eLD: hygrometer that is
04:03 AM Jin^eLD: but it has a built in hygrometer to keep the setting you choose with a knob, you just don't know how much it is if you don't have an additional device
04:04 AM MarcelineVQ: assuming my sensor is accurate they tend to stop being able to pull water at 25% humid or so, and work very well above 50%
04:05 AM Jin^eLD: MarcelineVQ: what target percentage did you go for?
04:07 AM MarcelineVQ: I usually have it start at 60+ and turn it off when it hits 40%. it'll depend how sensitive the device is and your climate
04:07 AM MarcelineVQ: For models with the sensor in the unit just turning it off can bump the reading up 10% since airflow stops and collected water can evaporate towards the sensor a bit
04:09 AM Jin^eLD: oh ok, so your target is around 50% then, but good to know about the 10% bump
04:09 AM Jin^eLD: it has an internal sensor so this probably applies to me as well
04:09 AM Jin^eLD: that's the one I got: https://uk.trotec.com/products-services/machinery-homecomfort/dehumidification/condensation-dehumidifier-of-the-ttk-series/ttk-100-s/
04:09 AM MarcelineVQ: I stop being concerned at 50%, partly because that's where the efficiency drops and partly because it's actually pretty dry as far as air goes
04:10 AM Jin^eLD: from what I read 50% should be fine if you worry about corrosion, so that was my target as well
04:10 AM MarcelineVQ: That's a similar size to the ones we have
04:10 AM MarcelineVQ: Maybe a little smaller
04:10 AM Jin^eLD: I first wanted to install heating, but then read deeper into the topic and it turned out that heating, well, only heats, but does not remove any moisture from the air
04:11 AM MarcelineVQ: Yeah, you'll find the dehumidifer will heat the space if it's a compressor type
04:11 AM XXCoder: hotter air would make humid extraction faster I think so
04:11 AM Jin^eLD: XXCoder: yes, they work best at warmer temps as they can produce a much bigger temp difference for condensation
04:12 AM Jin^eLD: I'll have to install a pipe for it though so I that I don't need to bother with emptying it manually
04:12 AM XXCoder: make sure it cant freeze
04:12 AM XXCoder: or pipe water to indoors weed plant lol
04:13 AM MarcelineVQ: Yeah we move ours around a fair bit so installing the hose never ended up making more sense than dumping manually
04:13 AM XXCoder: MarcelineVQ: indoors tomoto plant
04:14 AM MarcelineVQ: We do keep tomatos indoors but it's just to have trimmings to grow from in the spring :D
04:14 AM Jin^eLD: :))
04:14 AM XXCoder: nice. though maybe you can water it with humdifier output
04:15 AM XXCoder: with overflow that goes outside
04:15 AM Jin^eLD: we have a building with garage boxes and there is a drain in the center, so I can lay the pipe towards, indoors, won't freeze
04:15 AM Jin^eLD: no plants to water available :)
04:15 AM XXCoder: lol
04:16 AM MarcelineVQ: I'd rather have it shut itself off when it's full than risk pouring it out, and sucking that back up, and pouring that out, and sucking that backup :> If we had floor-drains upstairs that wouldn't be as much of a concern
04:17 AM Jin^eLD: :)
04:17 AM Jin^eLD: luckily we have that drain and its outside of my box, so I can keep my workshop well isolated
04:19 AM Jin^eLD: need to add some thermal isolation to the gate though
04:20 AM XXCoder: nice
04:20 AM Jin^eLD: and I am trying to figure out how to do a ventilation for welding fumes, i.e. how to make sure its isolated towards the outside so I can open/close the vent only when I weld
04:20 AM XXCoder: can always do store entrance type
04:21 AM Jin^eLD: store entrance? you mean double-gate or hot air or what are you referring to?
04:22 AM XXCoder: double door type yeah
04:22 AM XXCoder: *gate
04:22 AM Jin^eLD: I don't have that much space there
04:22 AM Jin^eLD: so I was rather thinking of sticking something on the metal gates or foaming them or something like that
04:23 AM Jin^eLD: but since we're talking about workshops, how did you guys solve your weld-fumes ventilation?
04:23 AM XXCoder: cheap way is freezer in reserant type plastic barrier
04:23 AM MarcelineVQ: working outside L>>
04:23 AM MarcelineVQ: :>
04:23 AM XXCoder: I solve it by not welding.
04:24 AM MarcelineVQ: I do get somewhat bothered when the wind blows away my shield-gas though <_<
04:24 AM Jin^eLD: MarcelineVQ: well, partially possible here, but MIG/MAG outside needs windstill conditions and is not that pleasant in winter or when it rains...
04:24 AM MarcelineVQ: I have a blanket I put up around the word hehe
04:24 AM MarcelineVQ: work
04:25 AM Jin^eLD: I bought ventilators that will be strong enough to suck out all the air out of the room within one minute (my nice now dry air!) but I need to figure out how to od the actual exhaust to the outside
04:25 AM Jin^eLD: so its not a permanently open hole
04:25 AM MarcelineVQ: Consider as well where the new air is coming from
04:25 AM Jin^eLD: I'll just have to open the gate
04:26 AM Jin^eLD: to allow incoming air
04:26 AM MarcelineVQ: is gate a term for garage door?
04:26 AM Jin^eLD: yes, garate door towards the inside of the building
04:26 AM Jin^eLD: basically its a big circle with garage boxes on the outer radius and nothing in the middle
04:27 AM Jin^eLD: each garage box has a 2m wide metal gate
04:27 AM Jin^eLD: a really weird building
04:27 AM Jin^eLD: and the boxes themselves are more like pizza slices, because the building is a big cylinder
04:27 AM Jin^eLD: so you have about 2m at the entrance and it gets wider towards the outer wall
04:27 AM XXCoder: isnt there just something like dryer air exit gate that closes when theres no air blowing?
04:28 AM MarcelineVQ: those are fairly common for dryers and kitchen hood vents but they're not especially insulating
04:29 AM Jin^eLD: I would hope so but so far I did only find some smaller things for useage in a bathroom in a flat or something
04:29 AM Jin^eLD: yes, exactly
04:29 AM Jin^eLD: they all are not insulated
04:29 AM Jin^eLD: and also too small for my ventilator
04:29 AM Jin^eLD: brb, courier
04:30 AM MarcelineVQ: A lot of people just have the kind that is a little hood, and a wire mesh on the inside to keep out vermin, it's possible there's not a lot of heat loss since there's not a lot of air exchange but idk
04:33 AM XXCoder: if theres gates on both ends there would be obly a little air movement
04:33 AM XXCoder: expecially if you design it so wind cant push cold air in, nor can increased cold air pressure push in much air
04:40 AM Jin^eLD: re
04:40 AM Jin^eLD: steadies for my lathe just arrived :^
04:40 AM MarcelineVQ: now you can cut your own leadscrews :D
04:41 AM XXCoder: :D
04:41 AM Jin^eLD: well, only shorter ones I guess? :) the main leadscrew is pretty long, I'd need a bigger lathe for that
04:41 AM MarcelineVQ: allthough I guess a follower is more the thing for that, oh well, plenty of work for a steady still
04:42 AM XXCoder: now, make a mill
04:42 AM MarcelineVQ: Jin^eLD: just make 3 and attach them together :>
04:42 AM XXCoder: make leadscrews you canb make one
04:45 AM Jin^eLD: :)
04:46 AM XXCoder: isnt aligning em very hard
04:46 AM MarcelineVQ: the first time, just gotta get a system down
05:12 AM Jin^eLD: oh so attaching was not a joke? I thought you were making fun
05:12 AM Jin^eLD: :)
05:13 AM XXCoder: https://www.arttec.net/ very nice site. jthornton check it out
05:21 AM jthornton: morning
05:21 AM Tom_L: 41F, Hi 39, Lo 29
05:21 AM Tom_L: right on the line of snow/rain
05:22 AM miss0r2: I just purchased the new Cat S61 phone. It better be as good as the S60! It was quite expensive
05:24 AM XXCoder: jthornton: what ya think of link lol
05:24 AM XXCoder: also, morning
05:24 AM miss0r2: if you want thermal camera build in, you don't have alot of choice when it comes to phones :) I bought the S60 because of the thermal camera - back then just because I thought it was sexy. Now I have come to rely on it :)
05:24 AM miss0r2: good morning XXCoder
05:24 AM XXCoder: whats you use it for?
05:25 AM miss0r2: For trouble shooting. excellent for electrics and hydraulics
05:25 AM miss0r2: if a machine does something it is not supposed to do, I just look at the control cabinet with the thermal camera to see if any of the relays are giving off excess heat. I've fixed quite a few problems with that approach
05:26 AM XXCoder: nice!
05:26 AM miss0r2: but the S61 is almost 1100 usd
05:26 AM XXCoder: used is still very expensive
05:27 AM miss0r2: yeah. You can buy my S60 for a good price, if you are interrested. :)
05:27 AM miss0r2: Everything works on it, but it has ALOT of cosmetical wear. Also; theres a small metal mesh protecting the speaker & microphone on the front that is missing (The reason I'm replacing it). The metal chips need to be removed from that unprotected hole manually
05:27 AM miss0r2: I guess I've just had enough of removing small chips from in there
05:28 AM XXCoder: honestly few $100s is much for toy
05:28 AM miss0r2: Indeed. You can have it for $100 ;)
05:28 AM jthornton: he is into a lot of stuff
05:29 AM miss0r2: I'm thinking $100 is what it is worth to me having it laying around as a spare :) I wasn't realy planning on selling it
05:30 AM XXCoder: author of that site? looks like hes in lot of clean power and management. though getting bit dated now
05:30 AM XXCoder: his mower for example, is made over decade ago
05:30 AM miss0r2: I love green energy stuff / living off grid
05:30 AM XXCoder: you would love that site
05:31 AM XXCoder: solar power, solar heating, solar water heating, solar mower
05:31 AM XXCoder: just that stuff there might not be buyable, or better versions out now
05:31 AM jthornton: mower is cool
05:32 AM miss0r2: that is a pretty neat idea :)
05:32 AM XXCoder: oh he updated some of article. one page hgas 2016,m replacement of voltage screen
05:32 AM XXCoder: guess hes still using mower
05:35 AM XXCoder: 40 watts 1 to 2 days before mower is charged. bit slow but if small enough yuard it dont matter
05:35 AM XXCoder: or get larger one
05:36 AM XXCoder: honestly I'd just have house solar panels recharge it also. much faster
05:38 AM XXCoder: I wonder if lathinium ion would work better lol
05:40 AM jthornton: flashing the sd card now gave up trying to copy the old sd card darn it
05:41 AM miss0r2: I have 9.6kwh worth of batteries in the basement. It is primarily charged with my small windmill. At the moment it is only tied into the basement lighting & computer equipment. But I will hook it up to the rest of the house at some point :)
05:41 AM miss0r2: Basically using the battery power until it is used up, and goes back to the grid supply. (not a huge windmill)
05:41 AM XXCoder: nice. homebrew windmill or?
05:41 AM jthornton: nice, what kind of batteries?
05:41 AM miss0r2: I thought about it :) but the small marina windmills are just so cheap
05:42 AM XXCoder: there is ... interesting design for windmill. its basically looks like a pole but top is little but wider than bottom
05:42 AM XXCoder: it abuses certain fluid properity so it spins in wind. doesnt care what direction it is
05:42 AM miss0r2: I know those, but they have an issue :)
05:43 AM XXCoder: yeah?
05:43 AM miss0r2: as far as I know; noone has managed to make bearings that lasts in that setup
05:43 AM jthornton: that maine guy is dyslexic too
05:43 AM miss0r2: or rather a setup that does not kill the bearings
05:43 AM XXCoder: what if you make air bearings?
05:44 AM miss0r2: I'm not sure tou can do airbearings that can handle the stress. But perhaps? :)
05:44 AM miss0r2: tou = if you* :)
05:44 AM XXCoder: no idea honestly
05:44 AM miss0r2: problem is the radial stress on the design.
05:45 AM XXCoder: though I wonder if some kind of pressuried liquid used as "balls" for bearings would be possible
05:45 AM miss0r2: a big electrical company in Denmark made some tests with the design, but had to abbandon it again because of the bearing life
05:45 AM miss0r2: highpressure oil bearings are a thing
05:45 AM XXCoder: expecially if such fluid is simple like water, and not complex like oil which do wear down
05:46 AM XXCoder: thats too bad. I recall another kind that uses disc
05:46 AM XXCoder: bah! marina windmill dont work in google
05:46 AM XXCoder: aliexpress has em apparently
05:46 AM miss0r2: Indeed. you just need to consider the 3rd kind of force excertion on bearings 1st; radial 2nd; axial 3rd; off angle lever forcer
05:47 AM miss0r2: and oil bearings & air bearings are notoriously bad for the last one
05:47 AM XXCoder: ironic. https://www.aliexpress.com/item/Desktop-Solar-Powered-Windmills-Model-Wind-Turbine-ABS-Plastic-White-Easy-Assembled-Solar-Powered-Windmill/32777872358.html
05:47 AM miss0r2: wtf is that :D
05:47 AM XXCoder: solar powered windmill display
05:47 AM miss0r2: lol
05:48 AM XXCoder: kinda tempted for lols.
05:48 AM miss0r2: Theres a law in Denmark that allows you to install a windmill without a permit, if the wingspan is smaller than 1.13meters - provided it does not annoy people around you
05:49 AM miss0r2: so, I have one of those. It provides three phase 48volt ~2000watt at 12m/s wind
05:49 AM XXCoder: 600w I wonder how much of house power it would cover for me
05:49 AM miss0r2: you'd need a battery bank
05:49 AM XXCoder: this location isnt "remote" of any kind so I doubt is usable lol
05:49 AM miss0r2: unless you want your light to dim up and down following the wind :D
05:49 AM XXCoder: it'd be rgeat for cutting some big power usage like AC or heater
05:50 AM miss0r2: Yeah
05:50 AM XXCoder: https://www.aliexpress.com/item/800W-12V-24-V-48-Volt-6-Nylon-Fiber-Blade-Horizontal-Home-Wind-Turbine-Wind-Generator/32855121721.html
05:50 AM miss0r2: I thought about installing an electric water heater as well. so dump the windmill power into that when the batteries are charged
05:50 AM XXCoder: that is quite small
05:51 AM XXCoder: is your region sunny a lot?
05:51 AM miss0r2: that looks ALOT like mine
05:51 AM XXCoder: how much did you pay for yours?
05:51 AM miss0r2: no, this is Denmark :)
05:51 AM miss0r2: 1500 usd IIRC
05:51 AM XXCoder: wow. aliexpress one is dirt cheap
05:51 AM miss0r2: but mine is a 2kw
05:51 AM XXCoder: probably brick in box
05:51 AM XXCoder: ah 2kw
05:51 AM XXCoder: one I linked is 300mm blade
05:52 AM XXCoder: or 600mm
05:52 AM XXCoder: yep 600
05:52 AM miss0r2: mine is 1013mm
05:52 AM miss0r2: Theres ofcourse a market in denmark for the 1013mm ones, as they comply with local law :D
05:52 AM XXCoder: lol https://www.aliexpress.com/item/Red-Green-White-Blue-Vertical-DIY-Small-Dc-Motor-LED-Windmill-Turbines-Wind-Generator-Model/32894587374.html
05:53 AM miss0r2: lol
05:54 AM XXCoder: most expensive https://www.aliexpress.com/item/20KW-220V-380V-horizontal-wind-turbine-power-generator-wind-mill-for-home-use/32921450985.html
05:54 AM miss0r2: yeah - that is slightly larger than mine :D
05:54 AM XXCoder: indeed. jthornton you can use that one im pretty sure. lol
05:55 AM XXCoder: power everything at your region
05:55 AM XXCoder: 2k w one https://www.aliexpress.com/item/2000W-2KW-48V-96V-horizontal-wind-turbine-power-generator-wind-mill-for-home-boat-use/32921418636.html
05:56 AM jthornton: nice big one
05:56 AM miss0r2: interresting
05:56 AM miss0r2: that can do the same at "only" 9m/s
05:56 AM XXCoder: 20kw that one. can power basically everything you own, at same tinme
05:56 AM miss0r2: mine needs 12m/s
05:56 AM miss0r2: XXCoder: provided its windy ;)
05:57 AM XXCoder: indeed
05:57 AM XXCoder: washington here its windy often
05:58 AM miss0r2: I live right next to a large field area. so I always have wind comming in from the same direction :)
05:58 AM miss0r2: and the horses are not offended by my windmill :D
05:58 AM XXCoder: cheapest https://www.aliexpress.com/item/2017-Hot-Selling-Wind-Generator-Wind-Turbine-200w-Combine-with-12V-24V-Option-wind-controller-3/32816986446.html
05:58 AM XXCoder: 300w
05:59 AM XXCoder: wait no 200w
05:59 AM miss0r2: one thing to consider when getting a windmill; you also need a MPPT unit
06:00 AM XXCoder: https://www.aliexpress.com/item/600W-Wind-turbine-Generator-Power-System-MAX-830W-Hybrid-1000w-Wind-Solar-Controller-wind-600W-solar/32780045445.html
06:00 AM XXCoder: whole kit looks like
06:00 AM XXCoder: 600w windmill, 1400w mppt
06:00 AM XXCoder: can have 2 windmills
06:00 AM miss0r2: indeed
06:00 AM miss0r2: So, instead of that dump resistor there, I was planning to use a water heater
06:01 AM XXCoder: mppt converts it to house usable power?
06:01 AM miss0r2: no
06:01 AM miss0r2: well, you can probally find one that can
06:01 AM miss0r2: But regularly they are for charging to a battery bank
06:02 AM miss0r2: You'll also need an inverter
06:02 AM XXCoder: interesting. one I linked to is wind power and solar, 800 max foir wind, 600w max for solar
06:02 AM miss0r2: I rebuild an old 5kw UPS
06:02 AM jthornton: what voltage does your battery bank use?
06:02 AM miss0r2: 48 volts
06:03 AM miss0r2: not rebuild, rather retrofitted it
06:03 AM miss0r2: an UPS outputs some realy nice sin wave, compared to your garden vareity converter
06:04 AM rmu: mppt for on-demand inverter use doesn't make much sense IMHO
06:04 AM miss0r2: rmu: You are right. you need a buffer in the middle; like a battery bank :)
06:05 AM miss0r2: there are some ready made units that can handle all of it; take in windmill output, charge batteries, change over when batteries are charged/discharged ect. But those units are pretty expensive
06:08 AM XXCoder: definitely cool. just not sure if I will ever try solar power or wind power lol
06:08 AM XXCoder: besides that toy one lol
06:08 AM miss0r2: hehe
06:08 AM miss0r2: It takes alot of work to tie it into the electrical installation
06:08 AM XXCoder: buy 10 of those toys, plant it somewhere and it will always solar
06:08 AM XXCoder: *light up
06:09 AM rmu: hmm. depends. there are units with mains plug, just plug them in, and they feed back power into the grid
06:09 AM XXCoder: as a evil bonus: make it a blinking led.
06:09 AM XXCoder: so it could get wind only once a while but can blink for years
06:10 AM miss0r2: rmu: Depending on where you live, you need a special aproval for that. plus; if your power meter is not build for it, you are just giving away all the power you cannot use yourself. I don't have a special deal, so I have to make do
06:11 AM XXCoder: honestly if you do nothing but just heat water with solars, you will have massive power savings anyway
06:11 AM XXCoder: heating water is expensive
06:11 AM rmu: miss0r2: i think in theory it should be possible in whole EU, given your power meter does "count backwards". but you are limited to 1kW or so
06:11 AM miss0r2: Indeed :)
06:12 AM XXCoder: https://www.instructables.com/id/Blinkies-Revisiting-the-LED-Throwie/ convert solar wind toy to this
06:12 AM XXCoder: it'd be literal immortal blinking led.
06:12 AM Jin^eLD: isn't it still the case that the panels are so expensive that you need 10+ years to break even?
06:13 AM XXCoder: jin solars has been getting real cheap but not sure on breakeven level
06:13 AM Jin^eLD: if you do it just to get off the grid somewhere remotely - that's another reason, but if its about savings then the breaking-even point is important
06:14 AM miss0r2: With my windmill setup, I broke even after 2.5 years
06:15 AM miss0r2: I did alot of the parts myself, which helps :)
06:15 AM miss0r2: but I think a good setup is around 4 years
06:15 AM XXCoder: not bad. yeah
06:15 AM Jin^eLD: thats nice
06:15 AM XXCoder: how much watts do water heater use anyway
06:16 AM Jin^eLD: if I wanted to save $$ I'd need to install an oven that works with old motor oil (have enough of that due to my car), but I don't want to have any open fire in the shed (except for torch welding)
06:16 AM Jin^eLD: they sell those ready-to use ovens in Poland I think
06:16 AM Jin^eLD: not really legal of course :)
06:17 AM miss0r2: XXCoder: They come in all sizes
06:17 AM XXCoder: lol ok
06:17 AM gregcnc: burning oil isn't legal?
06:17 AM rmu: last i looked solar panels (incl. inverter) were about 1€/Wp or less. at a price of 0,2€/kWh you need to run the panels 5000 hours at peak power to get back the investment. in 5-10 years it should be possible to break even. useful life of new panels is >10years.
06:17 AM XXCoder: gregcnc: depends on where
06:17 AM Jin^eLD: gregcnc: burning old motor oil is not :)
06:18 AM Jin^eLD: at least in the EU
06:18 AM XXCoder: I wonder if solar panels is refabishable
06:18 AM gregcnc: the local highway dept does it here
06:18 AM XXCoder: save it for kiln Jin^eLD
06:19 AM XXCoder: myfordboy made one that uses used oil
06:19 AM Jin^eLD: kiln?
06:19 AM XXCoder: err furance. to melt metal
06:19 AM Jin^eLD: oh
06:19 AM Jin^eLD: yes, a friend of mine has that
06:19 AM Jin^eLD: but we end up with too much oil, he does not melt metal that often
06:20 AM Jin^eLD: and then again I would not want to do that inside my workshop and since its in the city I am not sure if I could fire that thing up in front of the building ;)
06:20 AM XXCoder: part 2 https://www.youtube.com/watch?v=dQJbE16_czg
06:20 AM XXCoder: cant do it here also. middle of tacoma lol
06:21 AM Jin^eLD: whe have another friend who lives in a village and has a lot isolated space, so when we need to melt something we go there :)
06:21 AM miss0r2: I have a backyard :D
06:23 AM Jin^eLD: I was thinking about moving out of the city, but I dont think I'm ready for that, too used to comfort of not having to plan how much food to buy
06:24 AM Jin^eLD: take care of the house
06:24 AM Jin^eLD: etc
06:24 AM Jin^eLD: flat in the city is just more convenient somehow...
06:24 AM Jin^eLD: and then my wife would have troubles getting to work/university
06:25 AM Jin^eLD: but possibilities in terms of workshop/space would of course be really a lot better
06:26 AM XXCoder: I would like to try casting metal, but not alum but much lower temp metals
06:26 AM XXCoder: ones I can cast in wood and melt using steel bowl and regular heater
06:31 AM XXCoder: no worries about city laws with those. can wood + cnc router = fun cast molds
06:32 AM Jin^eLD: I think he tried cast iron with medium results and we did some aluminum hammers for sheet metal work
06:32 AM gloops: not sure how hot those gas fired mobile blacksmiths forges get, must be enough to get iron yellow, probably melt ally in that
06:32 AM Jin^eLD: and we also tried making molds by burning out 3D printed plastic
06:33 AM Jin^eLD: which actually worked pretty good, you could even see the structure from the 3D print on the aluminum
06:34 AM Jin^eLD: only issue was that the plaster where I put the plastic models in was not dry enough so it cracked a bit when burning out the plastic
06:39 AM XXCoder: jin saw some cool 3d print cast stuff yeah
06:40 AM XXCoder: want to try it but cant melt alum here
06:40 AM XXCoder: alum melt at 660c
06:41 AM XXCoder: im considering field metal for example. THAT melts at 70f. well above room temperarte but easy to melt
06:42 AM Jin^eLD: need to google up on "field metal", not sure I am familiar with the term
06:43 AM XXCoder: its safe metals alloys that have quite low melt temperate of 70f
06:44 AM XXCoder: looks like dull metal
06:44 AM Jin^eLD: but afterwards? what can you use them for?
06:44 AM Jin^eLD: i.e. in terms of strength/durability?
06:45 AM gregcnc: they are soft
06:45 AM XXCoder: yeah just for casting fun
06:45 AM XXCoder: different stuff
06:45 AM XXCoder: cast statue of some kind, later melt again for something else
06:45 AM XXCoder: something to do with cnc router besides just engraving
06:46 AM gregcnc: they have many uses. though i dont' think any melt at 70°F
06:46 AM XXCoder: fields metal does.
06:46 AM gregcnc: https://www.belmontmetals.com/product-category/low-melting-fusible-alloys/
06:47 AM XXCoder: dammit I meant 70c but yes
06:47 AM XXCoder: lol
06:47 AM gregcnc: sometimes poured into tubes to aid bending
06:47 AM XXCoder: 70f would be useless even for my idea of fun casting. it would melt in sumemrs
06:48 AM XXCoder: "cake" sized is 43 dollars
06:49 AM XXCoder: but I cant visualize what size it is
06:49 AM XXCoder: one cake is 2.5lb for 70c melt one
06:49 AM XXCoder: 170c can simple electric heater melt that?>
06:50 AM gregcnc: electric solder pot
07:20 AM jthornton: gotta roll up the garden hoses today for sure...
07:23 AM XXCoder: good idea. should do it here also. nights is at high 30s f'
07:24 AM XXCoder: night
07:24 AM jthornton: night

09:57 AM gloops: dovetails finally
09:57 AM gloops: https://ibb.co/fbzCcq
09:58 AM {HD}: Neat! Making drawers?
09:58 AM gloops: https://ibb.co/kGW8Hq
09:58 AM gloops: a blind man on a lame horse wouldnt see much wrong with those
09:59 AM gloops: just perfecting a vertical cutting method for them <{HD}>
09:59 AM gloops: boxes drawers, yeah handy for that kind of stuff
10:12 AM gloops: https://www.youtube.com/watch?v=XL18xJf0_Do&t=5s yes im going to look at the noisy pulley
10:17 AM jelly-home is now known as jelly
10:33 AM SaldoT: Hi. How do i go about troubleshooting QtQuickVcp/Cetus? Trying to install and configure it. Really easy it seems. Git clone and then - configserver -n 'My Machine' ~/Cetus
10:33 AM SaldoT: But nothing happens in the console after the last command.
11:31 AM fragalot: hi
11:52 AM gloops: look on my cnc dovetails fragalot and despair https://ibb.co/fbzCcq https://ibb.co/kGW8Hq
11:57 AM fragalot: i've always found them harder to do in pine than in hardwoods
11:58 AM gloops: oh yeah, its only test wood
12:04 PM gloops: nothing like a cnc cutting dovetails vid on facebook to upset the traditionalists though lol
12:36 PM SpeedEvil: gloops: add a variance for 'that hand-cut look at a hundred dovetails a minute'
12:37 PM gloops: yeah it wants that to achieve a 'cant believe its not hand-cut' look, it was just the first test
12:38 PM gloops: makes a very firm strong joint actually, better than leigh jig dovetails
12:41 PM {HD}: What does “DU” mean printed on a sealed bearing?
12:41 PM {HD}: 6202-625 6202DU
12:41 PM FinboySlick: gloops: Do you use a tapered endmill for the 'female' part?
12:42 PM gloops: Finboyslick no a straight endmill, board is held vertically
12:42 PM gloops: hence no fillets
12:42 PM FinboySlick: gloops: Well, that works for the 'big' ones. I'm not sure how you do the small ones.
12:44 PM FinboySlick: There's probably just something my battered brain is missing.
12:44 PM jthornton: {HD}: 6202 is the bearing size what comes after that is usually in indication of the shield(s)/seal(s) configuration
12:45 PM gloops: https://ibb.co/cq1vxq
12:46 PM FinboySlick: gloops: Yes, those are obvious. It's the part that meshes into that that makes me curious.
12:46 PM {HD}: jthornton: does 6202 represent a physical size or just a part number?
12:46 PM jthornton: it's a standard size
12:46 PM jthornton: google it
12:47 PM gloops: this is the toolpaths https://ibb.co/ca49OV
12:47 PM gloops: oh the tails - thats a dovetail cutter straight through
12:47 PM FinboySlick: OK.
12:48 PM gloops: https://www.youtube.com/watch?v=XL18xJf0_Do&t=5s
12:48 PM FinboySlick: 'get in there'.
12:48 PM FinboySlick: Hehe.
12:50 PM gloops: well, its got to be one pass lol
12:50 PM gloops: pretty slow code there that can be much more efficient
12:51 PM gloops: can also stack the boards and do 4 at once
12:53 PM {HD}: You could get a degree in “bearings“
12:55 PM FinboySlick: gloops: That a dual motor gantry?
12:57 PM miss0r|office: do any of you people have experience with keyence PLCs? I'm looking for the correct software to edit the program on a KV-10RW - I have ordered the cable, that was easy enough to find, but I can't even figure out what the software is called. Would any of you guys know?
12:58 PM JT-Shop: I've never had the pleasure of programming a keyence plc sorry
12:59 PM miss0r|office: I don't know if it is a pleasure, because neither have I.
12:59 PM miss0r|office: :)
01:00 PM JT-Shop: no keyence reps in your area?
01:02 PM miss0r|office: no official ones
01:05 PM JT-Shop: https://www.keyence.com/products/controls/plc-package/kv/index.jsp
01:06 PM JT-Shop: hmm seems to be a bunch of dead ends lol
01:06 PM miss0r|office: Yeah. But it is discontinued, and the software download one just says "sorry, no results were found."
01:07 PM miss0r|office: I think I struck gold: https://www.reddit.com/r/PLC/comments/9cakxq/help_finding_ladder_builder_for_kv_keyence_plc/
01:08 PM miss0r|office: But it would seem I *NEED* a 32bit pc to run it :]
01:08 PM * JT-Shop still has his windblows xp laptop for old shit
01:09 PM * miss0r|office looks at a pile of old laptops.
01:09 PM miss0r|office: I have no idea what you are talking about
01:09 PM JT-Shop: my old laptop has windows xp 32bit
01:10 PM miss0r|office: hehe. I have one running dos 6.22 :)
01:10 PM JT-Shop: and some old programs will only run on 32bit so I keep it around for that
01:10 PM miss0r|office: not that it will help me in this case.
01:10 PM miss0r|office: Indeed.
01:10 PM JT-Shop: yea something between dos and win 10 lol
01:11 PM * fragalot returns
01:15 PM fragalot: miss0r|office: just run it in wine. it's going to be fine.
01:15 PM gloops: FinboySlick yeah 2 motors on the X, nothing elaborate just some chinese steppers
03:16 PM Deejay: gn8
03:31 PM SaldoT: Good evening. Installed machinekit without gui, console only. Plan is to run gui using the machinekit app. How can i ensure machinekit is running and working?
03:31 PM SaldoT: Since i cant get QtQuickVcp/cetus to work yet
03:34 PM CaptHindsight: http://www.leadshine.com/productDetail.aspx?model=MX3660
03:35 PM CaptHindsight: anyone recall what the IO outputs do during power-up or when powered and the LPT port in the PC is being powered up and initialized?
03:42 PM jdh: sometimes, mine bounce on boot
03:44 PM CaptHindsight: I recall similar
03:44 PM CaptHindsight: had a led on an Output, it would turn on for second or so when something powered up
03:44 PM jdh: yeah. my spindle would spin
03:45 PM XXCoder: wonder if its best to turn pc on, then rest of cnc system?
03:45 PM CaptHindsight: was out in the field so I think we just kept the power off to the MX3660 until LCNC was running
03:46 PM jdh: yeah. my spindle control was just a ssr controlled ac outlet
03:46 PM CaptHindsight: OK wonderful
03:46 PM CaptHindsight: have to add more relays
03:47 PM CaptHindsight: it has that watchdog charge pump
03:48 PM CaptHindsight: guess that could be used IF it keeps the outputs OFF until it gets the signal
04:19 PM Blumax: Hello
04:19 PM Blumax: gloops, JT-Shop, result of my probe panel

05:58 PM * gloops puts his comfie-toes thermal socks on the radiator
05:59 PM CaptHindsight: I smell something burning, like wax
05:59 PM gloops: yeah Jean is like John which means hard as crucible steel with wolfs fangs
05:59 PM CaptHindsight: Larry, now there's a Viking name
06:00 PM CaptHindsight: strong yet friendly
06:00 PM gloops: hmm, well you dont want to know the most popular boys name in the nordic lands today
