12:00 AM Jymmm: Ok, so why would you want to use a 1lb tank on a trailer?
12:04 AM Wolf__: figured why not, seeing that I have 1lb type hose for my camping gear
12:04 AM Jymmm: OH, it's so you can connect to 1lb devices?
12:04 AM Wolf__: and it was all they had in store to make a hose up lol
12:04 AM Wolf__: yup, so you can run smaller cooktop or lantern
12:04 AM Jymmm: gotcha, I just refill my one lb bottles
12:04 AM Wolf__: I just run everything off 20-100lb tanks lol
12:04 AM Jymmm: I have a 12ft hose that connects to 5gal bbq tanks and the other end is like POL (disposable bottles)
12:06 AM Jymmm: Yeah, IF you have the hose(s), whcich most don't , at least not that length
12:06 AM Wolf__: use to camp often so have POL extension hose
12:07 AM Jymmm: My lantern/stove are both dual fuel (coleman/gasoline)
12:08 AM Wolf__: mine are ww2 or koren war era dual fuel lol, but usually would have at least one propane for ease of use
12:09 AM Jymmm: I have one lb tanks, but mostly as backup for the heaters and hand torch
12:10 AM Jymmm: Wolf__: This works GREAT btw https://www.harborfreight.com/propane-bottle-refill-valve-63607.html
12:10 AM Wolf__: actually, this set exactly https://www.ima-usa.com/products/original-u-s-korean-and-vietnam-war-coleman-gasoline-lantern-set-with-transit-chest?variant=26172563653
12:12 AM Jymmm: Wolf__: Mine https://www.amazon.com/Coleman-Premium-Powerhouse-Dual-Lantern/dp/B00006IS32/
12:14 AM Jymmm: and this https://www.amazon.com/Guide-Series-Dual-Fuel-Camping-Stove/dp/B00QMW5H76/
12:14 AM Jymmm: BUT....
12:14 AM Jymmm: If you want a damn cool little propane/butane stove, let me know
12:14 AM Wolf__: I have a couple of those type stoves as well
12:15 AM XXCoder: jynmm have one of latter heh 2 actually one is quite old from dad's
12:15 AM Wolf__: quite fun when you first fire them up lol
12:16 AM Jymmm: https://www.amazon.com/dp/B01HQRD8EO/
12:16 AM Jymmm: Damn cool lil stove
12:16 AM XXCoder: Wolf__: the little plunger is fun heh
12:17 AM Wolf__: my favorite https://classiccampstoves.com/threads/1942-coleman-520-civil-defense.26934/
12:17 AM Wolf__: great for freaking everyone out when you fire it up b/c it vaporizes the fuel off the burner plate
12:18 AM Jymmm: lmao
12:18 AM XXCoder: lol
12:18 AM Wolf__: first min or so looks like its out of control on fire
12:18 AM Jymmm: I'll stick with my alcohol burner for that stuff =)
12:19 AM Jymmm: I love that lil thing, have made coffee at 3am in the middle of a parking lot many many times
12:19 AM Jymmm: in the rain in the back of hte SUV
12:20 AM Jymmm: and soup for the national guard too
12:21 AM Wolf__: nice
12:22 AM Jymmm: Wolf__: https://www.aliexpress.com/item/Outdoor-Camping-Picnic-Stove-Mini-tiny-Spirit-Combustor-Copper-Alcohol-Stove-Burner-Gas-Stoves-Furnace-Portable/32899847086.html
12:22 AM Jymmm: I use denatured alcohol
12:22 AM Connor: Looking for good recommendation for bandsaw blade.. 93" x 3/4" for Aluminum bar and round, mild steel bar and round, also square and round thin walled.. Trying to figure out the best TPI for such a blade.. Non-production..
12:22 AM Wolf__: starret
12:23 AM Connor: just prototyping, for use in a community workshop where most people won't know what blade to use for what..
12:23 AM SpeedEvil: Thin walled stuff you generally want quite a lot of teeth, bar, few, so it's somewhat of a compromise
12:23 AM Connor: for use in a 7x12 drop saw
12:23 AM Jymmm: Wolf__: this one has a pot stand too... https://www.aliexpress.com/item/Camping-Stove-Portable-Aluminum-Mini-With-Brass-Alcohol-Stove-Burner-Compact-Lightweight-Backpacking-camping-equipment-stove/32946314790.html
12:24 AM Connor: You can cut bar with more teeth, just slower.. right?
12:24 AM Connor: I was hoping to find a variable pitch 14-18 tooth 3/4" wide.. so far, no luck.
12:24 AM Jymmm: Wolf__: or to save space... https://www.aliexpress.com/item/2019-Alcohol-Stove-Stand-Rack-Spirit-Burner-Base-Bracket-Stainless-Steel-Rack-Outdoor-Tools/32956203591.html
12:25 AM Wolf__: Lenox Classic Tuff Tooth Vari-Raker Band Saw Blade, Bimetal, Regular Tooth, Raker Set, Positive Rake, 101" Length, 3/4" Width, 0.035" Thick, 10-14 TPI is one of what I use
12:26 AM Connor: I need 93" :) 10-14 seams a bit too aggressive for thin stuff
12:27 AM Wolf__: we feed our shop saw lots of random stuff, 1/4 wall tube, 3/4 x 2 bar stock, 3/16 wall tube stock
12:27 AM Connor: https://www.northerntool.com/shop/tools/product_25226_25226 ?
12:27 AM Connor: Need to keep the dumb a$$es from trying to cut stainless on the thing..
12:29 AM Wolf__: http://www.starrett.com/category/saws/band-saws/21
12:30 AM Wolf__: have one of the intenss pro bimetal 6-10 on the shelf for same saw
12:37 AM Wolf__: I think 10-14 is the blade I got for thin stuff also =D
12:38 AM Connor: I'm not finding a 7'-9" x 3/4 10-14 iin the Intenss pro.. 6-10 is what they go up to.
12:39 AM Wolf__: https://www.amazon.com/Starrett-Intenss-Pro-Die-Bimetal-Neutral/dp/B003CYL6E0
12:39 AM Wolf__: but that is 1/2”
12:39 AM Connor: They have a 14 TPI no vairable in just the Intenss
12:46 AM Wolf__: might have to check lenox, I dont see anything like you said w/ high tpi count in 3/4"
12:49 AM pink_vampire: hi
12:51 AM XXCoder: hey pink
12:51 AM XXCoder: watching this heh https://www.youtube.com/watch?v=YXg1AKfj4x0
12:54 AM pink_vampire: hi XXCoder
02:25 AM Deejay: moin
02:25 AM _unreal_: 3am here
02:26 AM _unreal_: was out cold on my bed woke up because I was working on the project and passed out
03:08 AM XXCoder: good morning
03:32 AM _abc_: Hello. A step factor to leadscrew moved table of 320 or 640 comes from whence? I assume 200 step hybrid steppers, that gives 3.2mm pitch leadscrew? Is that correct?
03:34 AM sensille: _abc_: it also depends on your configured microstepping
03:34 AM _abc_: True. But no microspetting is fractional, right?
03:34 AM _abc_: *stepping
03:34 AM _abc_: Do they even make leadscrews with 3.2mm pitch? Not 3.15xx inch based?
03:35 AM _abc_: 640/200 = 3.2
03:35 AM _abc_: Looking at leadscrews of existing machines this is close, but do they really?!
03:37 AM sensille: they normally have 5mm lead
03:37 AM sensille: at least the ballscrews
03:37 AM sensille: leadscrews i know with 1.5, 2, 4 and 8mm as the most common
03:38 AM sensille: so 5mm lead, 200 steps/rev, 1/8th microstepping is 320 steps/mm
04:15 AM jthornton: morning
04:15 AM XXCoder: hey
04:15 AM XXCoder: check this out jthornton https://www.youtube.com/watch?v=bhx4VJg7qh0
04:18 AM jthornton: a lot of the letters seem to be very similar
04:19 AM XXCoder: u and v looks similiar when 3d model like that but easily differable by hand
04:19 AM XXCoder: plus detection isnt best thats why guy keep trying, expecially T
04:19 AM jthornton: yea I kinda thought the view angle was not the best
04:19 AM XXCoder: its from viewpoint iof signer
04:19 AM XXCoder: detection equipment is on other side
05:08 AM Tom_L: morning
05:08 AM Tom_L: 7F, Hi 25, Lo 11
05:14 AM Loetmichel: *gnah* original intel 1u cooling solution... metal mounting spider... so much burr on it that it that it shorted two ram lines under one screw... board: "*beeep*...*beeep*...*beeep*..." and i said to the coworker:"put some fibre washers under the mounting spider!" *repairing 3 mil pcb traces* :-(
05:22 AM XXCoder: Loetmichel: jeez lol
05:34 AM pink_vampire: I need to make few acryilic parts
05:35 AM XXCoder: for what?
05:35 AM XXCoder: arylic soemtimes crack and break
05:35 AM XXCoder: bit annoying
05:35 AM pink_vampire: my fish tank got larger filter, and the lamp leg is in the way
05:38 AM pink_vampire: i think i can just edit the one i did before
05:38 AM XXCoder: nice
05:39 AM pink_vampire: did you saw it?
05:39 AM XXCoder: nah
05:39 AM XXCoder: or maybe its been long while ago so cant recall
05:39 AM XXCoder: dont recall seeing you talk about fish tank so doubtful
05:41 AM pink_vampire: i took some pics for you
05:42 AM XXCoder: thanks :)
05:42 AM pink_vampire: https://i.imgur.com/ITGDtC5.png
05:42 AM pink_vampire: https://i.imgur.com/YQdlsba.png
05:43 AM XXCoder: ya its definitely on way
05:44 AM pink_vampire: i'm trying to make one leg very wide
05:44 AM XXCoder: how about just bent into tank?
05:44 AM XXCoder: matching curve of tank
05:44 AM pink_vampire: ugly
05:45 AM XXCoder: not quite as artistic yah
05:55 AM Loetmichel: pink_vampire: ouch... i would be careful with acrylic there. if that ages and breaks you have instant Bouillabaisse
08:02 AM SpeedEvil: Cut down the horizontal, and fit lights to inner part of tank?
08:03 AM pink_vampire: i just make new leg
10:11 AM Jymmm: WIFI water leak alarm https://www.amazon.com/dp/B0748RK2XQ/
11:10 AM Loetmichel: Jymmm: whats that for? to tell the insurance rep he can expect a claim in the near future?
11:10 AM Loetmichel: :_)
11:16 AM Jymmm: Loetmichel: To shut off the water before it damages the sub flooring and then you have a giant hole in the floor???
11:17 AM Loetmichel: Jymmm: isnt that a bit later if you have the water already on the floor?
11:17 AM fragalot: there is a difference between a few liters of water, and several hundred litres of water pouring around continuously
11:18 AM * fragalot did not see the context
11:18 AM -!- #linuxcnc mode set to +v by ChanServ
11:18 AM SpeedEvil: Flow meter and shutoff valve would also be useful.
11:19 AM SpeedEvil: 'more than I have ever used in one day in one hour'
11:19 AM fragalot: they make commercial pipe breach detectors
11:19 AM SpeedEvil: Indeed.
11:21 AM Loetmichel: Jymmm: i would probably go for the "standard" mechanical waterstop valves
11:21 AM fragalot: CaptHindsight: your job is in danger. https://www.youtube.com/watch?v=_h1ooyyFkF0
11:22 AM Loetmichel: and german houses are usually made from concrete and stone. not so much problems with a few cubic meters of water running down the stairs... unless you live in the cellar ;)
11:22 AM Jymmm: Loetmichel: and how do they tell is the HWH or washer drain hose is backedup/leaking?
11:23 AM fragalot: I can tell by the wet floor around the floor drain next to the washer
11:24 AM fragalot: but if the softener in the cellar would break.. well.. I would be able to tell by the water coming out of the air vent once it's fully filled up
11:24 AM fragalot: ._.
11:49 AM roycroft: hey folks
11:49 AM roycroft: i have a question about motor torque
11:50 AM roycroft: if i have a 3450rpm 3 phase motor that i run at half speed using a vfd, how will the torque compare to a 3 phase 1725rpm motor running at rated speed?
11:50 AM roycroft: will i lose a lot of torque running the faster motor that slowly?
11:53 AM fragalot: if I recall correctly, up to rated speed the torque should be constant, but the horsepower is mostly linear
11:54 AM fragalot: until you go above rated speed, where horsepower is constant but torque decreases
11:54 AM roycroft: ok, thanks
11:54 AM roycroft: and that sounds familiar to me
11:54 AM roycroft: i.e. don't push a motor past its rated speed or torque will drop off rapidly
11:54 AM fragalot: unless you don't need the torque
11:55 AM roycroft: and, this being for a belt grinder, i probably don't
11:55 AM roycroft: horsepower is what really matters
11:55 AM Jymmm: It was my understanding that that torque is inversely proportioal to the speed of the output shaft -- http://lancet.mit.edu/motors/motors3.html
11:55 AM roycroft: i don't plan on ever turning the grinder on under load
11:56 AM Jymmm: TORQUE/SPEED CURVES
11:56 AM Jymmm: ..of the motor.
11:56 AM fragalot: Jymmm: of DC motors
11:57 AM roycroft: my experience with 3 phase motors and vfds is that if i turn the frequency down too much the motor won't start
11:57 AM fragalot: yup
11:57 AM roycroft: but it has to be really low for that - like <10% of rated frequency
11:58 AM roycroft: and after it will start there's still a range where it where it's easy to stall the motor
11:58 AM roycroft: but iirc that's still at pretty slow speeds
11:59 AM Jymmm: fragalot: What, AC motors break the law of physics?
11:59 AM roycroft: i'm looking at running my grinder at up to 5000 sfm, but want to be able to slow it down to as little as 1000 sfm
12:00 PM roycroft: a 3450rpm motor with a 6" drive wheel runs at 5419 sfm
12:00 PM roycroft: so that's perfect
12:00 PM fragalot: Jymmm: no, but VFD's are at play, they do not output a constant DC voltage.
12:00 PM Jymmm: fragalot: ah, gotcha
12:00 PM roycroft: i'd have to run it at about 650rpm to get the low sfm speed that i want
12:01 PM roycroft: which is ~19% of the rated speed
12:01 PM roycroft: so that's getting down to where i might be concerned
12:02 PM fragalot: you could always go for a fancy dahlander (spelling?) motor with VFD :P
12:02 PM roycroft: i already have a 2hp motor for this project, but i'm looking to upgrade before i get started building it
12:02 PM roycroft: and the upgrade is not in the budget, so "fancy" is not a word that works for me here :)
12:03 PM fragalot: :D
12:03 PM roycroft: i'm hoping to find a motor for <$200, and if i get a 3450rpm one i think that's doable
12:04 PM roycroft: i just made an offer on a baldor
12:04 PM roycroft: my preference is to get a decent, us-made motor
12:04 PM fragalot: I thought you said fancy was not working for you
12:05 PM roycroft: that's not fancy
12:05 PM roycroft: fancy and crap are not two binary elements
12:05 PM fragalot: :D
12:06 PM gloops: 3hp seems an awful lot for a sander lol
12:06 PM roycroft: it's not a sander
12:06 PM roycroft: it's a belt grinder
12:06 PM fragalot: it isn't a sander
12:06 PM roycroft: and it's not overkill at all
12:06 PM fragalot: belt grinders need oomph.
12:06 PM roycroft: the rule of thumb is 1hp per inch width of belt is the minimum
12:06 PM roycroft: this is a 2x72 grinder
12:06 PM roycroft: so 2hp is the minimum
12:07 PM roycroft: 5hp would not be out of line
12:07 PM roycroft: more than 5hp would start to get ridiculous
12:07 PM roycroft: 3hp i think is quite reasonable
12:07 PM roycroft: my current grinder is 1x48, with a 1/2hp motor
12:08 PM roycroft: and it's so wimpy it gets frustrating trying to use it for even light grinding
12:09 PM fragalot: my current one is 1x24" at 150W and is beyond frustrating to use
12:09 PM roycroft: but it's an old belsaw, with a cast iron table, so i'll probably be able to pay for the new motor and drive wheel when i sell it
12:09 PM roycroft: the belsaw sticker on it is worth at least $100 :)
12:10 PM roycroft: i don't want to ever be replacing/upgrading the new grinder, other than adding more contact wheels/platens and tables/jigs
12:10 PM roycroft: the basic unit i want to last the rest of my life
12:11 PM roycroft: hmm, the seller just made a counteroffer and did not even remotely meet me in the middle
12:12 PM roycroft: i'll counteroffer in the middle and see how it goes
12:12 PM roycroft: we're still well under my $200 limit though :)
12:13 PM roycroft: another problem is that most 3 phase 3hp motors have a frame size that has a 1-1/8" shaft
12:13 PM roycroft: and i need 5/8" or 7/8" or else the drive wheel costs me a lot
12:14 PM roycroft: this one has a 7/8" shaft
12:14 PM roycroft: most single phase 3hp motors have a 5/8" shaft
12:14 PM fragalot: roycroft: build the same grinder that that guy on youtube is making
12:14 PM roycroft: but single phase motors are useless :)
12:14 PM roycroft: mine is based on jeremy schmidt's
12:14 PM roycroft: if that's the one you're talking about
12:14 PM fragalot: hang on
12:14 PM roycroft: it's very closely based on jeremy's
12:14 PM roycroft: i even bought his plans
12:15 PM roycroft: the work he did designing it is worth $20 easily
12:15 PM fragalot: https://www.youtube.com/watch?v=UXzoM-WXWRw
12:15 PM fragalot: THAT is a belt grinder
12:15 PM fragalot: jeremy's one is nice too though
12:15 PM roycroft: that's the motor i'm bidding on, btw :)
12:16 PM roycroft: and the seller agreed to my counteroffer
12:16 PM roycroft: so i'm good to go
12:16 PM fragalot: neat
12:16 PM roycroft: oh, he didn't - he wants to tack shipping on
12:17 PM fragalot: what you need now is a slab of 1 1/4" hardox for the frame
12:17 PM roycroft: which is going to put it higher than the original listing cost
12:17 PM fragalot: lmao
12:17 PM fragalot: sneaky
12:17 PM roycroft: yeah
12:17 PM roycroft: i did not accept
12:19 PM roycroft: i like the flexibility of jeremey's grinder
12:19 PM fragalot: yeah it's a very decent design
12:19 PM roycroft: i especially like the way he can flip the drive train without flipping the table
12:19 PM roycroft: that's what makes his stand out from the other designs
12:20 PM roycroft: i need to be able to precisely grind bevels on woodworking tools as well as my general metalworking needs
12:20 PM roycroft: and robert sorby make a nice little grinder for that
12:21 PM roycroft: https://www.robert-sorby.co.uk/sharpening/proedge/wped01a-proedge-system
12:21 PM roycroft: i'm sure i can make a platen with an indexable table to fit the schmidt design
12:24 PM fragalot: i've looked at that proedge a few times, but really couldn't justify it
12:25 PM roycroft: no, i can't justify the space nor the expense
12:25 PM roycroft: but if i can make a platen for the 2x72 that is essentially the proedge that would be brilliant
12:26 PM gloops: https://www.facebook.com/groups/847488865357217/ Home built belt grinders
12:27 PM roycroft: thanks, but i don't do facebook
12:28 PM roycroft: https://www.youtube.com/watch?v=a_RlL1O-bK4
12:28 PM gloops: some nice builds in there - roycroft you may as well, everyone else does
12:28 PM roycroft: that's essentially what i'll be building
12:28 PM roycroft: if everyone else jumps off a cliff into a vat of boiling oil, does that mean i "may as well"?
12:30 PM fragalot: depends on the oil's boiling point, and the ambient temperature / alternatives
12:30 PM gloops: id do it naked
12:30 PM fragalot: in the case of facebook however, the oil is also on fire, and the ambient temperature is 24°C with a humidity of 70%
12:30 PM roycroft: i suppose that in a vacuum the oil would not have to be very hot to boil
12:31 PM roycroft: the oil is also full of toxins that will kill one in an instant
12:31 PM roycroft: after stealing one's essential life forces
12:32 PM roycroft: but i'm not here to debate the relative merits and dangers of facebook
12:32 PM gloops: there are a lot of hobby-pro groups on facebook for hundreds of specific things, big source of knowledge and experience
12:32 PM roycroft: i'm just simply stating that i don't do facebook
12:32 PM roycroft: and that "everyone else is doing it" is not a valid argument
12:32 PM roycroft: i leave it to others to make their own facebook choices
12:33 PM gloops: i gudss my point is - everyone else isnt dead from using facebook, its your choice roycroft im not here to sell it
12:33 PM roycroft: not dead yet :)
12:33 PM roycroft: but seriously, i don't want to debate it
12:33 PM roycroft: please respect that i don't use it
12:33 PM roycroft: and i'll respect your choices regarding it
12:34 PM gloops: its not my business at all, pretty sure youd love the groups though lol
12:35 PM * roycroft refers gloops to the comments he made some moments ago
12:40 PM gloops: the one thing ive never searched facebook for = linuxcnc lol
12:40 PM gloops: so here goes
12:41 PM gloops: yes its there - only 76 members though
12:43 PM roycroft: i do need to get this motor issue sorted out asap, though
12:43 PM roycroft: i'm ready to start the build, and the tilting assembly is the second part of fabrication
12:43 PM fragalot: put a crank on it
12:44 PM roycroft: my current motor is flange mount, and i would prefer a base mount motor
12:44 PM roycroft: so i have to get that part figured out before i can really get started
12:45 PM roycroft: i could build the base assembly while sorting out the motor issue, but the base assembly and the tilting assembly use mostly the same sizes of steel bar/plate, so it makes sense to buy all of that at the same time
12:45 PM roycroft: and i can't generate a bom until i know how i'm going to mount the motor
12:46 PM roycroft: oh well, i need to wait for the snow to finish melting before i can make a steel run anyway
12:46 PM roycroft: and at the rate that's going, it could be another week before all the snow is gone :(
12:47 PM fragalot: can you not design the motor & mount as a completely separate element
12:47 PM fragalot: & get on with the rest of the build
12:48 PM gloops: id probably be thinking of a big angle plate with one end close - drill the end for the motor flange
12:52 PM roycroft: it would be easier to align things if the motor mount is part of the tilting assembly receiving tube if i'm going to use the flange mount motor
12:52 PM roycroft: and that would mean using plate instead of flat bar for that side of the tube
12:52 PM roycroft: i've only been planning on making this for two years
12:52 PM roycroft: another week or two isn't going to be the end of the world
12:53 PM roycroft: my only concern is that i'll lose my motivation and get distracted with a different project in the meantime
12:53 PM roycroft: and then, in the middle of that project, curse the fact that i don't have a decent belt grinder
12:53 PM gloops: you could slot the bottom of the angle for adjustment, i dunno its all work and time, a bottom mounting motor off the shelf is better of course
12:53 PM roycroft: because i curse not having one almost every day
12:54 PM fragalot: roycroft: sounds familliar, lol
12:54 PM roycroft: i have a motor, vfd, and the drive wheel, idler wheel, and platen wheels
12:54 PM roycroft: i've had all that stuff sitting in a box for 2 years
12:54 PM fragalot: sounds like my cnc build
12:55 PM roycroft: my cnc build is almost complete as far as materials
12:55 PM fragalot: got everything sittin in boxes kicking my shins into the damn things daily
12:55 PM roycroft: i still need ball screws, but i have everything else
12:55 PM roycroft: i've had everything for over a year
12:55 PM fragalot: I have everything apart from the gantry crane I need to be able to lift the damn castings
12:55 PM fragalot: thus.. i'm now working on a gantry crane for my 3x6 shed
12:55 PM fragalot: overhead gantry crane*
12:55 PM roycroft: i'm tired of bouncing around from project to project, and have resolved to complete existing ones before starting on a bunch of new ones
12:56 PM roycroft: other than a couple new projects that are already in the works as far as design
12:56 PM djdelorie: roycroft: if you figure out that secret, please share :-)
12:56 PM roycroft: djdelorie: i should be happy to do so
12:57 PM roycroft: please, however, do not hold your breath awaiting my secret
12:57 PM roycroft: i'd hate to see you turn blue
12:57 PM djdelorie: I'll put "don't hold breath" on my long list of proj... oh crap
12:57 PM gloops: only thing ive got to do is swap nema 23s for 34s, all there ready but i wont be doing it anytime soon, not an essential upgrade
12:57 PM gloops: less building, more using
12:58 PM fragalot: the trick is to use it to build parts for itself
12:58 PM roycroft: i know in my mind that if i complete some of the current projects i'll save a lot of time on future projects
12:58 PM fragalot: 90% of things made in job shops is for internal use anyway
12:58 PM fragalot: :D
12:59 PM roycroft: this belt grinder is something i just never get around to, especially since i already have one
12:59 PM gloops: mine doesnt cut steel, and is made of steel, so it doesnt self upgrade
12:59 PM gloops: besides its structually un-improvable
12:59 PM roycroft: but a few weeks ago i came to the realization that i use urrent one on almost every project i do
12:59 PM roycroft: and it frustrates me constantly
12:59 PM roycroft: so building the new one will probably be the biggest win for me
01:01 PM roycroft: so what's the deal with these dual hp rated motors
01:01 PM roycroft: i'm looking at a baldor 5hp/3hp motor
01:01 PM gloops: i could jump up and down on this gantry while its cutting
01:02 PM roycroft: is it 5hp at 460vac and 3hp at 230vac?
01:02 PM roycroft: rpm rating is also 1725/1425rpm
01:02 PM roycroft: that's probably a line frequency thing
01:03 PM fragalot: it is
01:03 PM roycroft: but the hp rating should not be frequency-dependent
01:03 PM fragalot: usually it's 380V though (here)
01:03 PM roycroft: i'm finding 5hp motors cheaper than 3hp motors
01:04 PM roycroft: 5hp motors usually have 1-1/8" shafts though
01:04 PM roycroft: that's a problem
01:04 PM fragalot: spin it up & push a file onto it :P
01:05 PM roycroft: i'd need to get someone to bore out my drive wheel and cut an new keyway
01:05 PM roycroft: which would probably cost as much as the drive wheel cost
01:05 PM roycroft: it could be an exercise in tight tolerance machining for me though
01:06 PM roycroft: the bore doesn't bother me much, but the keyway could be a bit tricky
01:06 PM roycroft: or an excuse to buy a broach set :)
01:07 PM roycroft: or i spend another $100 for a new drive wheel
01:13 PM fragalot: or $120 on a broach :p
01:14 PM roycroft: it's almost always better to spend the money on tooling
01:14 PM fragalot: yup
01:16 PM roycroft: a 5hp motor would require a new vfd as well
01:16 PM roycroft: so it's getting more expensive
01:16 PM roycroft: but a 5hp grinder would be awesome
01:23 PM roycroft: in a way i'm kind of unhappy that we have cheap vfds now
01:23 PM roycroft: before huan yang and its ilk 3 phase motors were dirt cheap
01:23 PM roycroft: but now they've gone way up in price, since folks can use them on single phase service
01:24 PM gregcnc: motors are just expensive now
01:24 PM roycroft: well, 3 phase motors used to be a fraction of the price of single phase motors
01:24 PM roycroft: now they cost more, generally, than a same hp single phase motor
01:25 PM gregcnc: used?
01:25 PM roycroft: yes
01:27 PM CaptHindsight: why come they are higher now? Copper prices, Chinese import duties, demand, automation, greed, liability insurance, minimum wage increases, tort reform, welfare moms?
01:27 PM fragalot: all of the above
01:27 PM gregcnc: right it's as if new replacement cost didn't change
01:27 PM fragalot: CaptHindsight: and inflation
01:28 PM roycroft: a big part is demand, as i was just discussing
01:28 PM CaptHindsight: immigration
01:28 PM roycroft: home shop folks used to get 3 phase gear and swap the motor out for single phase
01:28 PM CaptHindsight: how did I forget that excuse?
01:28 PM roycroft: resulting in a greater supply and lower demand
01:28 PM roycroft: now they can just get a vfd and use the 3 phase motor
01:28 PM roycroft: at the very least that decreases supply
01:29 PM roycroft: and being able to do variable speed cheaply increases demand
01:29 PM gregcnc: OK sure
01:29 PM fragalot: i was not aware i could run that 10kW compressor on single phase
01:29 PM gregcnc: industry consumes far more
01:30 PM gregcnc: fragalot why not?
01:30 PM CaptHindsight: illegal downloads
01:30 PM CaptHindsight: you wouldn't download a 3 phase motor
01:30 PM gloops: 14 items have been posted, time to lay off ebay
01:30 PM CaptHindsight: sure would
01:30 PM gregcnc: capt frosty here this morning
01:31 PM CaptHindsight: yeah, will it ever be spring here?
01:31 PM fragalot: gregcnc: service issues :-) house has 3ph, so single phase max power is lower
01:32 PM gregcnc: if you have three phase what's the problem?
01:32 PM gloops: https://www.ebay.co.uk/itm/3-phase-3Hp-electric-motor/333088642818?
01:32 PM fragalot: i was not aware i could run that 10kW compressor on single phase
01:32 PM whitequark: vfds are so expensive though
01:32 PM fragalot: :-)
01:32 PM gloops: £40 for the newman 3hp
01:32 PM fragalot: I spent $1k on a 240V -> 380V transformer to run the new tools i've been getting
01:32 PM fragalot: and run the lathe on a VFD
01:33 PM gloops: that will still be running when we're all dead
01:33 PM fragalot: power sources are a mess
01:33 PM fragalot: whitequark: single phase VFD's above a certain power level are expensive
01:33 PM gregcnc: you're not 400/3 over there?
01:34 PM fragalot: gregcnc: in some areas, but not in my street
01:34 PM CaptHindsight: https://www.eanpages.org/wp-content/uploads/2017/09/Figure-1_Brussels_floral_carpet.jpg carpets outside, need any more examples?
01:34 PM roycroft: a 5kw vfd with single phase input is about $225
01:34 PM gregcnc: they won't even let you walk on it....
01:34 PM gloops: https://www.ebay.co.uk/itm/10hp-3phase-motor-feet-fixing/173812143830?
01:35 PM gloops: giving 3phase away
01:35 PM roycroft: and that's for huan yang - not the cheap chinese clones of the huan yang :)
01:35 PM CaptHindsight: they refuse to take their shoes off
01:36 PM roycroft: https://www.surpluscenter.com/Brands/Marathon/5-HP-3475-RPM-380-VAC-MARATHON-ELECTRIC-MOTOR-10-115869.axd
01:36 PM roycroft: that's actually a pretty decent deal
01:36 PM gregcnc: fragalot I have phase converter and 240/400V transformer
01:36 PM roycroft: oh, wait, it's 380vac
01:36 PM roycroft: not 208/230
01:36 PM roycroft: i can't use it
01:36 PM roycroft: dang
01:36 PM roycroft: always a catch
01:37 PM gregcnc: why is printing from the web still a nightmare in 2019?
01:38 PM fragalot: lol
01:38 PM fragalot: DRM.
01:40 PM CaptHindsight: https://www.surpluscenter.com/Brands/Baldor/5-HP-3450-RPM-200-Volt-AC-3PH-Baldor-Motor-10-3167.axd

01:42 PM roycroft: 7.5hp is a bit much
01:42 PM roycroft: that's bordering on ridiculous
01:43 PM fragalot: do it. :p
01:43 PM roycroft: and about that 5hp model
01:43 PM roycroft: good price
01:43 PM roycroft: but baldor.com doesn't think that part number exists, so i can't find specs on it
01:43 PM CaptHindsight: Shpg. 103 lbs
01:44 PM roycroft: we had a server die last week during the snow storm/power outage
01:44 PM roycroft: i'm restoring backups of that server's vms to other hypervisors
01:44 PM roycroft: nd it's taking hours and hours at a time to copy a vm
01:44 PM roycroft: so i have plenty of time to shop for motors while that's happening :)
01:47 PM CaptHindsight: fragalot: I'm working on automating automation to make simple automation obsolete
01:48 PM fragalot: :D I expected nothing less from you
01:48 PM CaptHindsight: the term automation has been hijacked
01:48 PM CaptHindsight: i see it nearly everywhere now
01:48 PM roycroft: FAKE AUTOMATION!
01:49 PM * roycroft engages in some alternative automation
01:50 PM fragalot: i used copy/paste the other day to automatically transfer bits from one end to somewhere else
01:50 PM CaptHindsight: https://news.sky.com/story/thousands-face-incorrect-benefit-cuts-from-automated-fraud-detector-11651031
01:50 PM fragalot: rather that do that by hand
01:52 PM gloops: its a bit rough being on the dole here these days
01:53 PM gloops: used to be a very easy life for millions
01:53 PM gloops: people on life support have been judged fit for work etc lol
01:54 PM * roycroft , out of respect for the rest of the channel, refrains from commenting on the may regime at this time
01:55 PM gloops: im not making political views here btw, just an observation
01:55 PM fragalot: I want to get back to the old system of tenths
01:55 PM roycroft: i'm still zipping my lips on the subject :)
01:56 PM fragalot: I remember sitting in history class thinking "good lord people had to give up 10% yearly to the king? that's a LOT!"
01:56 PM fragalot: :D
01:56 PM roycroft: i thought you were going to say you want to go back to the old system of /d
01:57 PM fragalot: the what now?
01:57 PM roycroft: keep in mind that in the olden days, when you would give your tithe to the king, you would get absolutely nothing in return
01:57 PM roycroft: pounds/shillings/pence
01:57 PM fragalot: hell no, I like the euro
01:57 PM fragalot: I travel far too much to go back to the old belgian franks
01:57 PM roycroft: and when the king wanted to go to war he would just kidnap you and force you to fight in his army
01:58 PM roycroft: and take the tithe from your wife and children while you're "serving" (getting killed)
01:58 PM gloops: you got protection roycroft
01:58 PM gloops: the king was your protector, which is a necessary service when you arent allowed to bear arms
01:58 PM CaptHindsight: https://techxplore.com/news/2019-03-robot-artistic-grayscale.html
01:58 PM roycroft: except when the king did not protect you

01:59 PM fragalot: CaptHindsight: so they made a printer?
01:59 PM roycroft: without getting into a political discussion, i think we can all agree that an absolute monarchy is never good for th eproletariat
02:00 PM fragalot: roycroft: none of the systems are good in their pure forms
02:00 PM CaptHindsight: fragalot: who knew they could make such a thing?
02:00 PM fragalot: everything needs a healthy balance
02:00 PM fragalot: CaptHindsight: manbearpig
02:01 PM CaptHindsight: how abouts a technocracy, one OS to rule them alls
02:01 PM gloops: theres a lot to be said for the old aristocracy, 0 growth economy, barring conquest, they maintained the land, which was the source of all produce and means of life
02:02 PM gloops: centuries rolled by and nothing changed, nobody got any richer or poorer
02:02 PM CaptHindsight: that could be automated
02:02 PM fragalot: lol
02:03 PM CaptHindsight: program in some variances and some could get a bit more or less here and there
02:03 PM CaptHindsight: a king with one arm that you pull....
02:03 PM fragalot: farming is mostly automated now anyway
02:04 PM CaptHindsight: wheels spin around and you get a reward in coins
02:04 PM roycroft: in the western world farming is mostly automated
02:05 PM roycroft: in the vast majority of the world it is still very labor-intensive
02:05 PM CaptHindsight: how about an entire economy based on online sport betting?
02:05 PM fragalot: CaptHindsight: that's the UK in a nutshell
02:05 PM gloops: thats Rotherham
02:05 PM roycroft: the economy in the us is essentially based on betting
02:05 PM roycroft: stock market though, not sport
02:05 PM CaptHindsight: you work the fields for 8-10 hours a day and then you bet on who wins the basketball game to see how much you get paid
02:06 PM fragalot: CaptHindsight: :D
02:06 PM CaptHindsight: the basketball game is automated
02:06 PM fragalot: https://www.teejet.com/precision_farming/guidance.aspx <-- easy
02:06 PM gloops: i think 90% of the shops are bookies, pawn shops, £1 shops and charity shops
02:07 PM fragalot: gloops: lies, you also have a greggs everywhere
02:11 PM CaptHindsight: Putting a ship in a bottle https://www.youtube.com/watch?v=7zAtvrfiw8Y
02:11 PM fragalot: folding it feels like cheating
02:12 PM gregcnc: I can die now
02:12 PM gloops: making mesh models vertice by vertice is quite satisfying really, its the new knitting
02:12 PM CaptHindsight: does it work with all ships? I think not
02:12 PM fragalot: https://imgur.com/gallery/LEJQFQU
02:13 PM miss0r2: I think I, at best, could handle making shipwreck in a bottle
02:13 PM miss0r2: :]
02:13 PM fragalot: hehe
02:13 PM fragalot: how is that shipwreck of a siemens drive doing
02:13 PM miss0r2: All up and running
02:13 PM miss0r2: ;)
02:14 PM miss0r2: so there must've been a bad solder in there
02:14 PM fragalot: sweet
02:14 PM miss0r2: no matter how much monkey testing I did afterwards, I could not get it to fail
02:14 PM miss0r2: and its been running all weekend with incident
02:15 PM miss0r2: now I'm working on two camera trolleys that have to be shipped to congo on the 11th...
02:15 PM miss0r2: I got the order last friday... that is a pretty tight deadline
02:15 PM CaptHindsight: miss0r2: spent an hour soldering?
02:15 PM fragalot: miss0r2: xD
02:15 PM miss0r2: CaptHindsight: Indeed
02:16 PM fragalot: naturally the camera trolley came with clear instructions?
02:16 PM miss0r2: also, as is custom with that guy, he spends an hour or two of my time trying to figure out what he wants
02:16 PM miss0r2: no :D
02:16 PM fragalot: :D
02:16 PM fragalot: does he want another wooden 2x4 with a hinge?
02:16 PM miss0r2: same guy, but I scared him good last time :D
02:16 PM roycroft: cool
02:17 PM roycroft: i just got a us-made motor for $99, with $50 shipping
02:17 PM roycroft: that's brilliant
02:17 PM miss0r2: to complicate things further; the camera trolley needs to be ajustable from 300mm rail spacing to 600mm
02:17 PM miss0r2: and handle round pipe from 30mm up to 60mm
02:17 PM CaptHindsight: i find lotsa motors on craigslist
02:17 PM miss0r2: err; 640 rail spacing
02:18 PM miss0r2: plus be universal for 5 different camera mounting types
02:18 PM fragalot: miss0r2: as in 30 and 60mm, or 30->60 ?
02:18 PM miss0r2: the latter
02:18 PM fragalot: hur
02:18 PM miss0r2: I just about got the design down now. Tomorrow I will start machining
02:19 PM miss0r2: its gonna have alot of dovetails :]
02:19 PM miss0r2: and 14 wheels each
02:19 PM fragalot: sounds like it has to be able to actually carry something
02:19 PM miss0r2: man... I am realy on a tight deadline, the more I think about it
02:19 PM miss0r2: nah - maximum of 40kgs
02:20 PM gregcnc: lathework? https://www.instagram.com/p/BsbJw0YAv_G/
02:20 PM miss0r2: but the high number of wheels helps make the movement more smooth, if the surface is less than perfect
02:20 PM roycroft: capthindsight: there are very few "industrial" motors on my local cl
02:20 PM roycroft: i've been scouring cl constantly
02:20 PM roycroft: from seattle to eureka
02:21 PM fragalot: miss0r2: so is this more than your standard dolly / track slider application then?
02:21 PM gloops: how about something with a motor on it? old compressor for example
02:21 PM gloops: compressor worthless - but might have good motor
02:21 PM miss0r2: fragalot: Yeah. The design is hush hush for now. they are going to patent it
02:21 PM roycroft: $150 is a pretty good deal for a new, us-made 3hp motor
02:21 PM fragalot: alrighty then, fun if they get to patent the thing you're designing :D
02:22 PM roycroft: that's including dispatch
02:22 PM miss0r2: fragalot: Yeah. I'm contracted to get 20% earnings off that ;)
02:22 PM miss0r2: so I gave them 100kr/hour discount (13.40 ish eur)
02:22 PM gregcnc: guy built a cnc plasma cutter into his truck https://www.instagram.com/p/BdtO2kwnfQm/
02:22 PM roycroft: i still need a drive wheel for this
02:23 PM roycroft: but that's ok
02:23 PM miss0r2: if they don't get it and don't sell alot of them; meh.. if they do, great :)
02:23 PM fragalot: miss0r2: Good luck :-)
02:23 PM roycroft: i can start the build without the drive wheel, now that i know what the motor footprint is
02:23 PM fragalot: miss0r2: "do it for the exposure" :P
02:23 PM roycroft: the drive wheel i have has a 5/8" bore, and this motor has a 7/8" shaft
02:23 PM miss0r2: hehe.. those 100kr/hour does not make the world of difference to me. so, its a pretty low risk investment for me
02:23 PM roycroft: more importantly, the drive wheel i have is 5" in diameter, and i want a 6" wheel to get a bit more speed
02:24 PM miss0r2: so, I just thought; what the hell
02:24 PM fragalot: miss0r2: showoff. :D
02:24 PM miss0r2: lol.
02:24 PM miss0r2: My hourly wage is inflated alot compared to what I need. I had to do that to be taken seriously.
02:24 PM miss0r2: Strange how the world works sometimes
02:25 PM roycroft: you can set up a foundation with your surplus wages, miss0r2
02:25 PM miss0r2: In the beginning I was too cheap; so I did not come into consideration when people needed a repair guy. because "they wanted someone better". So, I upped my wage 100% and they were like "come on in"
02:26 PM * roycroft would love to be a professional philanthropist, but never bothered to amass an obscene amount of money, so will likley not choose that as his next career path
02:26 PM miss0r2: lol
02:26 PM roycroft: there's much to be said for giving away money to do good things
02:27 PM miss0r2: yeah
02:28 PM miss0r2: Not to sound like a holy person or anything; But I enjoy what I do enough, that I don't need to get payed an insane amount
02:28 PM miss0r2: professional satisfaction is realy important
02:28 PM miss0r2: no, not that kind of satisfaction, you pervert. (fragalot)
02:28 PM fragalot: is there any other kind?
02:28 PM miss0r2: :]
02:30 PM roycroft: i guess now i have to find something to do with this 2hp motor
02:30 PM roycroft: new project opportunity!
02:30 PM miss0r2: cnc lathe spindle!
02:31 PM roycroft: actually
02:31 PM CaptHindsight: obsessive compulsive money collector
02:31 PM roycroft: i do want to replace the motor on my 12x36
02:31 PM roycroft: but a flange mount motor would be difficult to mount on that
02:31 PM roycroft: when i got the lathe my plan was to replace the motor with a 3-phase one and a vfd
02:32 PM roycroft: mine is a belt drive lathe, and i hate changing the belt configuration to change speds
02:32 PM roycroft: i'd rather turn a knob
02:32 PM CaptHindsight: what is a person thinking if they ask you why an item is priced so high if an item is listed as some number and "or best offer"?
02:32 PM roycroft: 2hp would be the perfect size motor for that lathe, though
02:33 PM CaptHindsight: does the number intimidate them?
02:33 PM roycroft: a lot of sellers set a really high buy it now price because they don't have any clue what the item is actually worth
02:33 PM roycroft: and they add a "make offer" button to see what folks are willing to pay for it
02:33 PM roycroft: but then they decline every offer
02:33 PM roycroft: and sometimes, when the listing expires, they relist at a more reasonable price
02:34 PM CaptHindsight: sure
02:34 PM CaptHindsight: test market
02:34 PM roycroft: "make offer" is just a research tool
02:34 PM CaptHindsight: same with CL, you raise the price until you run out of offers
02:35 PM roycroft: i'm pretty good at knowing what stuff is worth
02:35 PM roycroft: when i put together bid packets for multi-million dollar fiber optic projects, my engineer's estimate is usually within 5% of the winning bid price
02:36 PM roycroft: estimating seems to be one of my strengths
02:36 PM CaptHindsight: i come across people that feel that >30% profit margin is immoral
02:36 PM CaptHindsight: maybe even 20%
02:36 PM roycroft: it all depends on what it is
02:36 PM Tom_L: yeah i think it should be 50 or more
02:37 PM roycroft: at a supermarket, 30% margin on food is obscene
02:37 PM roycroft: that's a 2-3% margin market
02:37 PM Tom_L: do those same ppl shop at thrift stores?
02:38 PM roycroft: when purchasing a bespoke piece of furniture, 50% margin is not unreasonable at all
02:38 PM Tom_L: what's the margin on fuel?
02:38 PM CaptHindsight: is there some sort of church that teaches profit margins?
02:38 PM roycroft: tom_l: whatever the market can be coerced to bear at the moment
02:38 PM Tom_L: supply & demand
02:38 PM roycroft: it is quite variable
02:38 PM syyl: i think thats church of satan, CaptHindsight
02:38 PM roycroft: no, it's not really supply and demand at all
02:38 PM syyl: they focus on personal development and success
02:38 PM * miss0r2 pokes syyl photo time?!
02:39 PM roycroft: because oil companies create fake crises to jack the cost of fuel way up
02:39 PM roycroft: and rake in the profits
02:39 PM roycroft: they do it for as long as they can
02:39 PM Tom_L: we all caught onto that in the 70's
02:39 PM roycroft: until people start not using as much fuel
02:39 PM roycroft: then they drop it way down to get people addicted to it again
02:39 PM roycroft: lather, rinse, repeat
02:39 PM CaptHindsight: no, no, they just keep finding the missing oil later
02:39 PM CaptHindsight: it's like a TV remote
02:40 PM roycroft: whenever suv/pickup sales go down and tiny car sales go up, the price of gasoline drops significantly until gas-guzzler sales recoup
02:41 PM syyl: because people need a 2ton pickup to get groceries
02:41 PM roycroft: petroleum is probably the second-most highly manipulated market we have
02:41 PM roycroft: next to pharmaceuticals
02:41 PM syyl: and printer ink
02:41 PM syyl: ;)
02:41 PM roycroft: yes, i forget about that one
02:41 PM miss0r2: syyl: don't forget; a two ton pickup with a tempered injection system, so the smoke is pitch black
02:41 PM roycroft: because it's stupid to use inkjet for almost everything
02:41 PM gloops: there is always the bicycle
02:41 PM syyl: agreed, roycroft
02:41 PM syyl: :D
02:41 PM roycroft: i have a nice commercial copier that costs next to nothing to operate
02:42 PM CaptHindsight: it's the R&D costs
02:42 PM syyl: i have a cheapish HP laserprinter, it runs on power and hot air
02:42 PM CaptHindsight: inkjet like drugs take years of testing
02:42 PM syyl: the toner cardridge shows "low" since 500 pages or so
02:42 PM CaptHindsight: same for oil
02:42 PM miss0r2: I use inkjet.. because it is cheaper to buy a new printer, than buying new chartridges
02:42 PM roycroft: capthindsight: the va do a lot of research and drug development
02:42 PM miss0r2: (not even kidding)
02:42 PM CaptHindsight: you just can't drill anywhere and strike oil
02:43 PM roycroft: and they can put a new drug on the market for a tiny fraction of what the commercial pharmeceutical companies claim it costs them
02:43 PM miss0r2: CaptHindsight: Guided drilling; start in your backyard, and suck your neighbooring country dry :)
02:43 PM roycroft: i paid $2500 for the printer i have currently
02:43 PM roycroft: but it's a nice commercial model - it does color up to 12"x18", and, most importantly for me, has a high speed scanner
02:44 PM miss0r2: I payed $34 us for the printer I have right now. (printer/copyer/scanner).
02:44 PM roycroft: i've been trying to go paperless, and have scanned tens of thousands of documents with it
02:44 PM miss0r2: it comes with those "small" chartridges, but they last me a year in my small buisness
02:44 PM roycroft: i've had this one for 3-4 years now
02:44 PM roycroft: i've probably printed 2000 pages
02:44 PM roycroft: but scanned tens of thousands
02:44 PM roycroft: that's the primary reason i got it
02:45 PM roycroft: also, i used to have an 11x17 b&w printer - big hp model on a big cart, a texas instruments 12x18 color copier that used some very nice, but very expensive, wax-based toner, and an older color hp copier that did 8-1/2x14 with a duplexer
02:46 PM fragalot: I got a €60 2nd hand color laser printer
02:46 PM roycroft: so three big machines
02:46 PM fragalot: it.. just works.
02:46 PM roycroft: i got rid of all of them and use this one for everything
02:47 PM roycroft: https://www.ebay.com/itm/371741695368
02:47 PM roycroft: that's the model i am currently using
02:47 PM miss0r2: I better catch some sleep - alot of machining tomorrow. See you around
02:47 PM roycroft: and the place where i work is a print shop as well as an isp, and they have all konica printers
02:47 PM roycroft: so i have access to tech support
02:47 PM roycroft: when i have a probem i just ask a technician when he's working on one of the office machines
02:48 PM roycroft: anyway, it is lunch time
02:55 PM CaptHindsight: I print lots on paper I buy at a store with an actual cashier and get driven there by a hired driver in clothing grow on organic farms and hand stitched by tradespeople of unknown genders
02:57 PM CaptHindsight: saving the money would be like freezing energy in a bottle and never used
02:58 PM fragalot: CaptHindsight: but do you use free range squid ink to print with?
02:58 PM fragalot: or are you more of a lapiz kinda guy
02:59 PM CaptHindsight: I make my own inks with my own hands from materials sourced from free range people
02:59 PM CaptHindsight: they are only bounded by their imaginations
03:00 PM fragalot: I prefer free range minecraft squid ink
03:00 PM fragalot: I have an automated farming setup for that
03:00 PM CaptHindsight: lapiz dancers
03:00 PM fragalot: downloads to the blockchain every hour
03:02 PM CaptHindsight: just because people do something doesn't mean they aren't entitled to get paid for it
03:04 PM fragalot: shocker
03:05 PM fragalot: but it could be corrected to "just because people do something doesn't mean they are entitled to get paid for it"
03:06 PM CaptHindsight: what if they were making a profit for years, doesn't that mean that they should continue to do so?
03:06 PM fragalot: they should. whether they can is a different story
03:06 PM fragalot: markets change
03:07 PM CaptHindsight: obviously they were not evil since they were blessed by profits
03:09 PM CaptHindsight: good over evil obviously :)
03:09 PM fragalot: good or evil has little to do with it
03:09 PM fragalot: being evil usually gives you much better short term profits
03:09 PM fragalot: long term if you're good at it
03:10 PM CaptHindsight: oh a you'll probably say that there is no angry invisible man in the sky behind all this
03:10 PM CaptHindsight: oh a
03:10 PM fragalot: the angry one is down below
03:10 PM fragalot: :P
03:10 PM CaptHindsight: makes sense
03:57 PM Wolfmetalfab is now known as Wolf__

04:31 PM andypugh: OK, so I have an NSK Mega-torque servo, a servo drive and an NSK “Handy Terminal”
04:31 PM andypugh: Like this
04:31 PM andypugh: https://www.ebay.co.uk/i/111333147652?chn=ps
04:32 PM andypugh: (And feeling smug that I spent £175 for the full set)
04:33 PM DaViruz: that alpha-numeric keyboard seems strange
04:33 PM DaViruz: don't think i've ever seen that for a motor controller or similar
04:35 PM andypugh: Looks like commands like “M0” to turn off the motor
04:36 PM andypugh: I think it is actually an RS232 serial terminal
04:41 PM DaViruz: nice find regardless, i find it pretty hard to find servos and especially useful drives on ebay
04:41 PM DaViruz: a stand alone terminal like that might be useful in other circumstances, hm
04:48 PM andypugh: Indeed
04:51 PM DaViruz: i wonder if it can be configured for different baud rates etc
05:42 PM andypugh: Well, so far I don’t seem to be able to turn the drive on.
05:43 PM andypugh: it _might_ need 24V on the enable pin.
05:43 PM andypugh: (Seems odd to need an external 24V supply though)
05:46 PM andypugh: Though it seems pretty unambiguous… https://imagebin.ca/v/4Z53Vipxp5ad
05:48 PM Tom_L: maybe once it's in service it's not required
05:49 PM Tom_L: or not..
05:49 PM andypugh: It says “always required”
05:49 PM Tom_L: i see that now
05:50 PM andypugh: I will try that tomorrow
05:50 PM Tom_L: almost tomorrow :)
05:51 PM andypugh: A $1000+ drive without an intenral +24V?
05:54 PM Tom_L: seems so
05:58 PM skunkworks: megatorque!!
05:59 PM skunkworks: DaViruz: used to be amc drives go for cheap on ebay.. Haven't looked lately
06:35 PM _unreal_: sup....
06:35 PM _unreal_: well I got the LAST major thing I needed done to this shell I'm building for the computer side... and now I can start looking at software finally
06:36 PM _unreal_: I do need to re-design the power system a little bit but that is the least of my worries
06:40 PM _unreal_: I'm uploading some new photos
06:40 PM _unreal_: got my remote SD card adapter mounted
06:41 PM _unreal_: Now I can have my SD card accessable from the outside easy even though its "plugged" into the SD card socket on the tinker board
