12:10 AM Lcvette[m]: Wolf, how are you liking the new motor?
12:17 AM jesseg: `Wolf, ahh no back gear?
12:21 AM XXCoder: a week of high 80s, but high 50s/low 60s night. not too bad
12:21 AM XXCoder: hot work at start but cools off pretty fast
12:23 AM Wolf__: jesseg: nope, no back gear on my mill
12:24 AM jesseg: Do you find you miss it? I've wondered if they are worth all the extra work when its rebuild time
12:24 AM Wolf__: if you look at the parts photo for my mill, no back gear in the design
12:30 AM jesseg: yeah that's what I thought I was seeing but I'd thought back gears were kind of universal
12:31 AM Wolf__: its only a 1hp/0.5hp two speed motor on it, I don’t think it was ever intended for heavy cutting w/ larger cutters
12:32 AM Wolf__: makes it great for small work tho
12:32 AM jesseg: yeah, makes sense
12:35 AM Wolf__: bigger mill after I get a larger shop space setup =)
12:38 AM jesseg: exactly
12:38 AM Wolf__: mean time I get to figure out how I’m going to hook the new motor up on this thing
12:40 AM connor_goodwolf: ya'll need to set +r on the group
12:40 AM connor_goodwolf: this is how spammers are getting lists and spamming via PM the users
12:41 AM jesseg: connor_goodwolf, must be from another channel you're getting that
12:42 AM jesseg: I've gotten pm spams months ago, but haven't seen any when this latest attack was going on
12:46 AM Rob is now known as Guest98085
12:48 AM connor_goodwolf: jesseg: possibly, I just know I've set +R on myself so I don't get spam
12:48 AM jesseg: cool
12:48 AM connor_goodwolf: the spambots haven't registered nicks
12:51 AM Wolf__: I haven’t had any spam PM yet
12:52 AM connor_goodwolf: they may be using other groups, I just noticed this group doesn't have +r
01:01 AM norias: hello
01:06 AM jesseg: howdy!
01:06 AM norias: how goes/
01:06 AM Wolf__: morning
01:07 AM norias: morning
01:08 AM XXCoder: connor_goodwolf: channel silences on $~a! so unregistered can read but cant say anything
01:09 AM Wolf__: ^ we get to watch them join then get K-Lined
01:10 AM XXCoder: we need a bot that voices unregistered after say 2 or 3 minutes
01:10 AM XXCoder: bots gets hammered well before that I think
01:11 AM Wolf__: they have been making it about 10-20 sec lol
01:11 AM XXCoder: voice bypasses the quiet setting
01:11 AM XXCoder: 40 seconds then lol
01:57 AM Deejay: moin
01:57 AM norias: howdy
02:21 AM sealive: hi all
02:21 AM sealive: norias, still on
02:21 AM norias: yeah
02:22 AM sealive: im in germany
02:22 AM norias: oh, cool
02:22 AM sealive: here is my info channel for Linuxcnc https://www.youtube.com/channel/UCmwhCL92ZQRSVqFe3jGwJSQ/videos
02:24 AM Wolf__: norias isnt new to the channel =)
02:25 AM Wolf__: and why am I still up…
02:27 AM sealive: Wolf__, you like the WWW and your CNC
02:27 AM norias: https://markforged.com/metal-x/
02:28 AM norias: this is cool
02:28 AM norias: 3d printing of sintered metals
02:28 AM sealive: norias, ther may be at the Car Factorys running 100+ at this moment
02:29 AM norias: maybe
02:29 AM norias: i'm sure someone is buying them
02:29 AM sealive: norias, it olny looks that clean if out of factory and printed part is positiond on table
02:29 AM Wolf__: well, thats different, is that FDM + sintering?
02:29 AM sealive: then it is a dust hell
02:29 AM norias: Wolf__: yeah
02:30 AM norias: which, imho, should be very cost effective
02:30 AM norias: because it's really not that different than MIM
02:30 AM norias: just no mold
02:30 AM Wolf__: yeah, thats a new one to me
02:30 AM norias: i.e. i don't think it will help you compete with MIM
02:31 AM norias: but it should be closer in cost on small runs
02:31 AM norias: a good path
02:31 AM sealive: im off 2 Garden
02:32 AM Wolf__: bunch of demo SLS on bid spotter in PA right now lol
02:32 AM norias: heh
02:32 AM norias: i was actually thinking of doing this at one point
02:32 AM norias: getting a shit furnace
02:32 AM norias: and a shit 3d printer
02:32 AM norias: get some MIM powder feedstock
02:33 AM norias: and some injection molding pellets
02:33 AM Wolf__: lol I have both of those…
02:33 AM Wolf__: rest I have no clue about =D
02:33 AM norias: i think you need an argon atmosphere
02:33 AM norias: and decent control on the heat cycles
02:33 AM norias: i've worked in places that ran those kind of furnaces, but never done it myself
02:33 AM Wolf__: arduino check, 330cu argon check
02:34 AM norias: get some powder and pellets
02:34 AM norias: make some fdm feedstock
02:34 AM Wolf__: thats the part I’m lost at lol
02:35 AM Wolf__: I bet the kiln/furnace I have wont get high enough
02:35 AM norias: dunno
02:36 AM Wolf__: plus I still need to put it back together, rear refactory got cracked
02:37 AM Wolf__: 2350F/1287C I think
02:38 AM norias: the one here is 1300C
02:38 AM norias: so...
02:38 AM norias: maybe?
02:39 AM Wolf__: massive 6”x6”x6.25” 1440W =)
02:40 AM norias: $100k
02:40 AM norias: pretty reasonable
02:40 AM norias: wonder what the entire system costs
02:42 AM Wolf__: https://www.bidspotter.com/en-us/auction-catalogues/bscpres/catalogue-id-bscpres10070/lot-f525bfa0-3815-46ea-968a-a91c016bea3a wonder what the reserve is
02:42 AM norias: apparently this thing has been out there for a year
02:42 AM norias: and i've just missed it
02:44 AM norias: oh shit
02:44 AM norias: that $100k is with the furnace
02:44 AM Wolf__: so thats the turn key price, not too crazy in the long run
02:45 AM XXCoder: isnt that machine usually 500k or million bucks?
02:46 AM norias: not this one
02:46 AM Wolf__: that FDM + stinter your paying probably 60k of that just for them coming up for the idea lol
02:47 AM Wolf__: you’re
02:47 AM norias: uh, i doubt it
02:47 AM norias: the idea was obvious
02:48 AM norias: i think the formulation of the feedstock and developing the processing is actually where it's at
02:48 AM norias: plus, it probably does all the shrinkage calcs for you
02:48 AM norias: etc
02:48 AM Wolf__: yeah, kinda what I actually meant, words are hard at almost 4am w/out sleep =)
02:54 AM norias: fuuuuuuuuck
02:54 AM norias: people are talking about using it for injection mold cavities
02:54 AM norias: print-sinter-post process
02:54 AM Wolf__: oo
02:55 AM norias: interestingly, i wonder if controlled porosity would actually be _better_ for injection mold cavities
02:55 AM norias: pore sizes large enough to get air out, but too small for the injection front
02:55 AM norias: it'd simplify mold design a little
02:55 AM norias: and probably end up requiring less packing pressure
02:55 AM Wolf__: intersting idea
02:56 AM norias: if that were the case...
02:56 AM * Wolf__ knows not much about die making
02:56 AM norias: you might be able to just inject water through the pores
02:56 AM norias: to do cooling
02:56 AM norias: i.e. air goes out of pores ahead of plastic
02:57 AM norias: cavity is full, inject water
02:57 AM norias: eject part, drain water
02:57 AM Wolf__: wouldnt the water eject the part
02:57 AM norias: might increase cycle times with lower packing pressure
02:57 AM norias: no, i don't think you'd need much pressure
02:57 AM Wolf__: depending on part design of course
02:57 AM norias: plus do it while the mold is closed
02:58 AM norias: crazy ideas, but my crazy ideas have worked in the past
02:59 AM Wolf__: lol
03:00 AM Wolf__: crazy ideas are usually the good ones
03:01 AM Wolf__: if it works, then more tool and die shop auctions for me to get stuff from
03:02 AM norias: lol
03:07 AM Wolf__: if it makes millions I could use a 40’x60’ pole building as well =P lol
03:08 AM norias: heh
03:08 AM norias: fucking stamping dies, too
03:09 AM norias: they didn't mention it
03:09 AM norias: but there's no reason you can't do tungsten carbide with this stuff
03:09 AM Wolf__: I wish all my projects went simple.. lets put a new motor on the mill… now looking at how to turn multi ribbed V belt pulleys…
03:11 AM Wolf__: damn, that idea really would kill off tool and die shops
03:13 AM Wolf__: on the other hand, it would probably be a hell of a boost in productivity to getting parts from design to production run I bet
03:18 AM norias: naw, tool and die would just adapt
03:18 AM norias: edm didn't kill them
03:18 AM Wolf__: last auction lots came from a tool and die shop that was full of edm machines
03:18 AM Wolf__: that I picked up
03:18 AM norias: they didn't die because of edm
03:19 AM Wolf__: near Reading PA, probably lack of business
03:19 AM norias: i could see this going hand in hand with EDM
03:19 AM norias: the electrodes are really easy to machine quickly
03:20 AM norias: just, as we know, edm takes forever
03:20 AM norias: but what if you 3d print the part near net
03:20 AM norias: edm to final
03:20 AM Wolf__: quicker cycle times
03:20 AM norias: right
03:20 AM Wolf__: prints could be run lights out
03:20 AM norias: yeah
03:21 AM Wolf__: or just 24/7 lol
03:21 AM norias: the other thing in the mix that's kind of interesting is the extrude hone system
03:21 AM norias: using a non-newtonian fluid
03:21 AM Wolf__: eh
03:21 AM Wolf__: oh cool
03:21 AM norias: as the base for a lapping system
03:21 AM norias: they make machines for that
03:22 AM norias: i chatted with them once
03:22 AM Wolf__: https://i.imgur.com/7Qm7f56.jpg no more lol
03:22 AM norias: in theory
03:22 AM norias: you could make a machine that mounts injection mold tools
03:22 AM norias: run that stuff through the runner system in the mold
03:22 AM norias: and polish the mold exactly in the flow direction
03:22 AM norias: with no labor
03:23 AM norias: fun stuff
03:23 AM Wolf__: neat concepts
03:23 AM norias: yeah
03:23 AM norias: i need to start doing something
03:23 AM norias: it's all talk until chips get made
03:23 AM Wolf__: yup
03:24 AM norias: i should probably sleep soon
03:24 AM norias: but now i'm almost too excited to sleep
03:24 AM Wolf__: lol
03:25 AM norias: i tell people this when i interview for jobs
03:25 AM Wolf__: no one in here knew what that diprofil was when I posted the pic
03:25 AM norias: manufacturing excites me
03:25 AM Wolf__: then again, I didn’t know what it was till about 5mins before I bought it off one of the facebook groups lol
03:25 AM norias: lol
03:27 AM norias: ok
03:27 AM norias: i'm out
03:27 AM Wolf__: lol later, same here
04:28 AM connor_goodwolf: XXCoder: the problem is they're entering the groups, getting the user list and spamming via PM
04:29 AM XXCoder: havent gotten any I think its running down ABCs
04:29 AM XXCoder: and my nick is double x
04:29 AM XXCoder: you could make message only from registered onl;y
04:50 AM connor_goodwolf: XXCoder: I did that, but this doesn't help others here
04:51 AM XXCoder: yeah not perfect system
04:55 AM jthornton: morning
04:55 AM XXCoder: yo
05:18 AM miss0r: goodday
05:22 AM Deejay: heya
05:22 AM Tom_L: 77F Hi 98
05:35 AM jthornton: 71°F 94 for the high
05:36 AM jthornton: chicken coop is 73.4F 78.6% 1004.4 hPa
05:43 AM miss0r: I'm not sure what exactly it is around here, but it is alot better than the past few months. Today you can actualy breathe
05:43 AM miss0r: and the wind has picked up a bit, which is nice
05:44 AM miss0r: The hot air killed my compressor... :-/
05:44 AM XXCoder: this weel will be hot. not hell hot like 2 weeks ago but..
05:44 AM XXCoder: then friday rain. 100 accients maybe. wed rain failed to appear
05:45 AM miss0r: hehe. The weather forecast tells me that the hot weather will come back wensday with a vengeance
05:45 AM miss0r: :-/
05:45 AM miss0r: I'll just enjoy the mild conditions for now
05:45 AM XXCoder: people here dont know how to drive in rain, expecially after months of no rain
05:45 AM miss0r: I'll bet. Its the same all over the world.
05:46 AM XXCoder: not really
05:46 AM XXCoder: here is 50th best state for driving
05:46 AM miss0r: hehe. I forgot you're an american ;)
05:46 AM XXCoder: if youre not sure there is 50 states. lol
05:46 AM miss0r: I know :)
05:47 AM XXCoder: yeah was joking
05:47 AM miss0r: Here in Denmark, we have a metric shitton of accidents each year when the first snow falls...
05:47 AM XXCoder: I wasnt joking about 100 accients where I live each dang time theres rain after prolonged no rain
05:47 AM miss0r: I mean; ITS SNOW!
05:47 AM miss0r: That is just scary
05:47 AM XXCoder: snow isnt hard to drive on really
05:48 AM miss0r: nope
05:48 AM miss0r: but for some reason some people find it hard
05:48 AM XXCoder: just dont speed and do excessive change of speed
05:48 AM miss0r: yeah.. keep the g-levels at a minimum
05:48 AM SpeedEvil: Don't be a jerk.
05:48 AM XXCoder: I take foot off gas at the twice the distance to light
05:48 AM miss0r: SpeedEvil: Clearly you don't know me - that is like telling a fish not to swim or a bird not to fly
05:49 AM SpeedEvil: (that would work better if jerk was not the derivative of accelleration tbh)
05:49 AM XXCoder: I drove like old man 15 years ago
05:49 AM XXCoder: I drive like slightly older man now
05:49 AM miss0r: SpeedEvil: Yeah, I see what you were getting at.. lol :)
05:49 AM XXCoder: indeed. lol
05:50 AM miss0r: I drove like a maniac in my mid teens. (16-18). In Denmark you can't get your drivers lisence before the age of 18. So 16-18yos drive mopeds..
05:51 AM miss0r: I actualy installed a nitrous kit on a 70cc moped... meh. I'm glad I got all of that out of my system in the early days
05:51 AM miss0r: and lived to tell
05:51 AM XXCoder: :)
05:51 AM XXCoder: I probably would speed a bit if I had license 5 or 8 years earlier
05:52 AM XXCoder: but then im not much of risk taker
05:52 AM miss0r: the moped I build is actualy still on display at a place called 'scooter gallery'.. if you are interrested, you can see the nitrous install here: https://www.scootergalleri.dk/galleri/38078-yamaha_aerox_solgt
05:52 AM miss0r: :)
05:53 AM XXCoder: the strange assembly at air exit?
05:53 AM miss0r: at air exit? :S
05:53 AM XXCoder: I cant spell that word so yeah lol
05:53 AM XXCoder: extust something
05:54 AM miss0r: Ahh, the strange shape of the exhaust ?
05:54 AM XXCoder: yeah
05:54 AM XXCoder: i dont see how it'd help to have nox there
05:54 AM XXCoder: maybe using it as prewarmer?
05:55 AM miss0r: :S the nox is under the seat
05:55 AM miss0r: that strange thing you see on the exhaust is just a muffler
05:55 AM XXCoder: interesting
05:55 AM miss0r: You have to scroll down a little bit on the picture series on the right
05:56 AM miss0r: The exhaust is shaped that way with a small entrance pipe and a small exit pipe, to have the exhaust gass cool down in the 'large' section. This creates some suction that helps pull out the echaust gasses from the next combustion faster
05:57 AM miss0r: I had this monstrosity on a dyno. It had 28hp. keep in mind that it is only 70cc and the whole things weighs around 90 pounds
05:57 AM XXCoder: makes sense, motor air flow higher the more powerful
05:58 AM miss0r: Yeah. I'll get back to installing the new compressor *sigh*
06:01 AM XXCoder: fun
06:20 AM miss0r: New compressor in, and operational :D What a blessing. Ive been running the cnc for two days, without being able to use an air pistol... That sucks !
06:23 AM XXCoder: man I need one lol
06:25 AM * Loetmichel just had a 30mm SiC grinding disk explode in the milling spindle... at 24krpm... thanks to myself that i mounted swarf guards made of 4mm PC on the router...
06:26 AM Loetmichel: qas quite an bit shaken from th3e *BANG* and the funny scratch spider in the polycarbonate. loess than a foot from my face ;)
06:27 AM Loetmichel: -o
06:29 AM miss0r: :o
06:29 AM miss0r: Did it wreck anything?
06:33 AM Loetmichel: just the swarf guard
06:33 AM Loetmichel: tried to grind down a "clamp on" type of ferrite choke ... either the ferrite is as hard as SiC or even harder... just got waaay to hot but didnt do a thing to the choke
06:34 AM Loetmichel: just the grinding stone exploded
07:43 AM miss0r: A friend of mine just stopped by with two boxes filled with odd sized drills, endmills, shell mills, reamers carving tools, slitting saws and a bunch of other fun stuff :) I think there must be 100+ endmills in there ranging from 0.3mm to 12mm
07:43 AM miss0r: They just threw it out where he works, because they are not categorized :D
07:48 AM miss0r: Now I have a like 5 or 6 0.95mm H7 helical reamers :D
07:55 AM JT-Shop: pcw_home: do I need to supply 5v to P3 to get the I/O pins on the 7i96?
07:57 AM JT-Shop: hmm I have 5v supplied to P3 but don't see any inputs or outputs
08:07 AM JT-Shop: I see hm2_7i96.0.ssr.00.out.00 is that the output pin?
09:20 AM pcw_home: JT-Shop: yes, hm2_7i96.0.ssr.00.out.00 is output 0 (of 0..5)
09:21 AM pcw_home: inputs 0..10 are just GPIO 0..10 at least until the INM module is supported
09:22 AM JT-Shop: ok thanks
09:25 AM pcw_home: P3 5V is the same as TB2 5V
09:27 AM dan3wik is now known as dan2wik
09:33 AM JT-Shop: thanks
09:34 AM * JT-Shop heads off to work
10:40 AM Loetmichel: *hrhr* the world is so small... one big village. just "aquired" our ex-apprentice at the company (now he is the "network manager") to help me get the bed from my cars roof... he drives behind me home... arriving he said: "oh, i was here often two years ago. my sister used to live in this house on third floor"... now that he says it: there was a woman there with the same surname as him... and
10:40 AM Loetmichel: i work 2 cities away from home ;)
10:55 AM rmu|w: Loetmichel: six degrees of separation
10:55 AM Loetmichel: ?
10:56 AM rmu|w: every living human being is connected to every other human being via at most 6 shared acquaintances
10:57 AM rmu|w: or even 5
10:59 AM cradek: I've heard that too, but it seems pretty unlikely
11:05 AM jdh: perhapsit was a typo, should have been 16
11:09 AM robotustra: let's count, let's say I know 200 people, if they know 200 in average - it means I know (200-1)^2 people. and so on.. 200^6 = 64 000 000 000 000
11:10 AM robotustra: it's much more than 8 000 000 000
11:11 AM robotustra: so if the average person knows ~100 people, he or she knows all population of the earth in 6 connections
11:12 AM robotustra: rmu|w, so it's close to truth
11:25 AM sealive: hi all
11:26 AM robotustra: hi
11:26 AM robotustra: how is the weather in Germany?
11:27 AM sealive: melting oven
11:27 AM sealive: 37.4 here
11:28 AM robotustra: in Montreal it's getting colder, 21 degree will be tonight
11:28 AM sealive: here 2 from thursday arctic cold will flow in
11:28 AM robotustra: but day temperature is about 30
11:28 AM robotustra: not so bad
11:32 AM robotustra: sealive, according to manuam mesa board 7i76 can handle from 8V to 32V field power
11:32 AM sealive: 24V is standard and all E-components are on that value
11:32 AM sealive: ptimised
11:32 AM sealive: opti
11:33 AM robotustra: there is a voltage regulator on the board
11:33 AM robotustra: next to the power connector
11:33 AM roycroft: it's getting hot again here in eugene - 35 today
11:34 AM robotustra: it's an compensation for cold winter
11:37 AM rmu|w: i will not hold for _everybody_, but if you allow a "small" number of exceptions (i.e. <2% or so) to account for weirdos and really disconnected communities it will probably hold
11:38 AM sealive: robotustra, still up to you but 24V is never a fault to bring in a PSU to the mashine
11:44 AM robotustra: sealive, yeah, I got it. it means that I have to use separate power supply for mesa board and servos, because my servos eat from 20 to 50V
11:45 AM robotustra: at 50V they have the max torque
11:46 AM sealive: i woudt say 72
11:46 AM sealive: 72V on a 2.3V Stepper gives you speed
11:46 AM robotustra: :)
11:47 AM sealive: robotustra, the new Higtech Digital Drivers get then the rest towars 60000Steps per second
11:50 AM sealive: robotustra, i checkt on same mashine 800kg Gantry 30:1 Tb6600 M542 M860H DM556
11:50 AM sealive: at 36V
11:50 AM sealive: 7.5meter Cable length
11:50 AM sealive: High impendent 1mm²
11:51 AM robotustra: so you mean 24V is more than enouph?
11:52 AM sealive: AWG17
11:52 AM sealive: 5Times the Stepper Voltige is Best
11:52 AM robotustra: My cables will be < 2 meters
11:52 AM sealive: AWG24
11:52 AM sealive: up to 5A
11:53 AM sealive: Speed is near Double
11:54 AM robotustra: ok I'll start with 24V and if it will be not enough - will make a separate power supply for servor
11:55 AM robotustra: I have the servo like this guy on the video https://www.youtube.com/watch?v=I4PshKtwpqs
11:55 AM sealive: robotustra, did you see my cabinetts
11:55 AM robotustra: no
11:55 AM sealive: this is My YT https://www.youtube.com/channel/UCmwhCL92ZQRSVqFe3jGwJSQ/videos
11:56 AM sealive: robotustra, cabinetts Video i use https://www.youtube.com/watch?v=Ee-Yq8EQPSU
11:56 AM robotustra: ah, I did see it
11:56 AM robotustra: huge router
11:58 AM sealive: my biggest is 12meter by 7meter
11:58 AM sealive: robotustra, to cut Foam Carneval parts
11:59 AM robotustra: to build airplanes?
12:00 PM robotustra: interesting idea: https://www.youtube.com/watch?v=6PY9WQN9K6g
12:02 PM robotustra: it might be not so rigid
12:03 PM robotustra: sealive, my lathe will be small, 90x50x50 cm max dimensions. so the cable length will be not more than 2 m
12:04 PM sealive: robotustra, did you see my XYUVB mashine for cutting Wings
12:04 PM sealive: robotustra, and the Python based Linuxcnc internal shape genrator on the wing contour
12:05 PM sealive: robotustra, it has 10000 wing shapes inside
12:05 PM sealive: with 4 layers Mill and 2 Layers Hotwire
12:07 PM robotustra: no, show me

12:10 PM robotustra: cool
12:10 PM gregcnc: are there many using that? does it allow for sheeting thickness?
12:11 PM sealive: greg yes
12:11 PM sealive: i got near 12000hits
12:11 PM sealive: gregcnc, the thickness is calculated on the length
12:12 PM sealive: Width
12:12 PM sealive: my dauthers shop is no longer online i need to change this
12:13 PM gregcnc: but can you adjust the wood sheeting thickness?
12:14 PM sealive: if you change width it changes thickness
12:14 PM gregcnc: width of what?
12:14 PM sealive: profile
12:14 PM gregcnc: so it doesn't account for sheeting thickness
12:14 PM sealive: the shape is internal so with gifes hight
12:15 PM sealive: the wing length is from profile to profile
12:15 PM sealive: if you make spans you need to get it to your need at the length you want
12:16 PM sealive: gregcnc, robotustra NEW link http://heimwerkermarkt-tretter.de/airfoil.zip
12:16 PM sealive: gregcnc, robotustra you need python-pil
12:17 PM gregcnc: http://www.smrcc.net/Tips/Construction/FSSection.gif
12:18 PM sealive: gregcnc, yust unpaxk it and use it to see the output
12:29 PM sealive: gregcnc, did yu testit
12:29 PM gregcnc: no
01:10 PM sealive: im off
01:10 PM Rab: test
01:10 PM Rab: Success!
01:13 PM skunkworks: did you hear something?
01:15 PM Rab: A visual bell.
01:19 PM skunkworks: Shhhhh... do you smell that?
02:38 PM pcw_mesa: Libre le potato is a hot potato compiling a kernel with J4...
03:51 PM LilyFaith: Anyone here? I am a network admin. I know almost nothing about manufacturing, but I work for a manufacturing company. We have a bunch of old excellon CNC 6's attached to Mark V drills. I was originally brought over to figure out if there is a way to upgrade the 5.25 inch drives to USB drives. But my question is why do we need these Excellon CNC 6 controllers from the 70s at all? This software seems like it should do what we
03:52 PM LilyFaith: The PC? I know that isn't a simply question but if someone could point me in the right direction to get started I would appreciate it
03:53 PM andypugh: I guess you have a whole bunch of excellon drill files?
03:53 PM andypugh: LinuxCNC can almost certainly control the drills, but you might need G-code files rather than your current toolchain.
03:54 PM andypugh: Do you have a model number for the drills? We can try to Google for clues.
03:58 PM andypugh: Hmm. I guess I won’t spend any more time looking for info on Excellon drills then.
04:01 PM jthornton: it left?
04:04 PM Loetmichel: maan, thats the fifth liter of water i drink today... boss should buy an A/C for the company...
04:05 PM CaptHindsight: Loetmichel: no AC at the shop!?
04:05 PM Loetmichel: indeed
04:07 PM Loetmichel: only in the measurement chamber to keep the electronics cool
04:07 PM CaptHindsight: I bet Lily stopped over at GRBL or some *duino channel
04:07 PM Loetmichel: we had 41°C in the workshop today ;)
04:08 PM CaptHindsight: 23C here today and most of the week <30C, actually getting a break
04:10 PM CaptHindsight: looks like Loetmichel should stay dry in the next few decades...
04:10 PM Loetmichel: dry???
04:10 PM Deejay: gn8
04:11 PM CaptHindsight: Loetmichel: at the sea level rises and northern Europe becomes more arid
04:12 PM CaptHindsight: I was looking over the long term forecast from back in the 70's based on global warming by deg C
04:55 PM JT-Shop: hazzy-dev: hazzy-lab hazzy-m you around?
04:56 PM hazzy-lab: JT-Shop: yes
04:56 PM JT-Shop: made some good progress this morning and when I got home from the industrial park
04:57 PM JT-Shop: not much left to do with the basic stuff
04:57 PM hazzy-lab: excellent!
04:57 PM JT-Shop: I'm saving the I/O information to the ini so I can read it and setup the wizard
04:58 PM JT-Shop: I was assuming it was going to be convoluted but it turned out to be pretty easy
04:59 PM hazzy-lab: hmm, that is a good idea!
04:59 PM * hazzy-lab goes to check it out
04:59 PM * JT-Shop wanders off to sit with the chicks
05:55 PM jthornton: looks like $750 of #2 copper to run to the new shop
05:57 PM jthornton: although it's running on #10 at the moment
06:01 PM Tom_L: you gonna run something big out there?
06:01 PM jthornton: dunno, the panel is a 100 amp panel
06:01 PM jthornton: I do want to do it right
06:02 PM Tom_L: i ran 6 to mine but it was because i had it
06:02 PM Tom_L: i think i put it on a 50A breaker but i'd have to look for sure
06:02 PM jthornton: the run is 225' so a bit of a voltage drop
06:02 PM Tom_L: yeah a little
06:03 PM Tom_L: you gonna bury it or run a pole?
06:03 PM jthornton: I have 2" conduit in a 2' deep ditch
06:03 PM jthornton: as well as a 3/4" for data and a 3/4" for water
06:03 PM Tom_L: yeah, i put 2 in back when i poured the slab for my garage
06:04 PM jthornton: I finally got 30' or so of conduit buried so I could get to the door without running over a wire lol
06:04 PM jthornton: now I'm hot to finish it up
06:05 PM jthornton: picked up a 200 amp outdoor panel with 8 slots to feed the house, shop/garage and new shop
06:05 PM jthornton: I want to be able to flip a main breaker off and fire up the generator
06:09 PM Tom_L: i've got my gen wired back thru the welder outlet in the garage so when i flip the main i can run off the gen with little effort
06:11 PM * hazzy-lab just wires the gen into the main panel when it is needed ...
06:11 PM hazzy-lab: lol
06:11 PM jthornton: when I built the house I ran from the meter into my panel, now I have the generator connected to the garage panel so to isolate the meter I have to pull it out to run the generator
06:12 PM jthornton: hazzy-lab: did you get a chance to look at the config maker?
06:12 PM hazzy-lab: I did!
06:12 PM hazzy-lab: It looks great
06:12 PM jthornton: thanks
06:13 PM jthornton: I think it
06:13 PM jthornton: 's right close to being able to make a configuration
06:13 PM jthornton: once I get that done I'll work on the error checking
06:13 PM hazzy-lab: It looks very close, I guess I/O is all that is left?
06:14 PM jthornton: I just have to read the I/O when I load the ini
06:14 PM hazzy-lab: ok
06:15 PM jthornton: everything else about the I/O is done, it writes to the ini and creates the io.py file with all the proper connections
06:16 PM hazzy-lab: sweet!
06:17 PM jthornton: yea got home from the industrial park and it started to rain so I got more done on it this afternoon
06:17 PM hazzy-lab: I need to spend a little time reading thru your code a bit more thoroughly
06:23 PM jthornton: lol I just let the cat out of the bag on the forum
06:23 PM Tom_L: woops
06:26 PM jthornton: say goodnight Gracie
07:07 PM hazzy-lab: jthornton: Just could not wait any longer, could you ;)
07:36 PM robotustra: which smartphone is to buy
07:36 PM robotustra: I just broke the screen on mine :(
08:34 PM `Wolf: ugh, my eye and brain hurt, been reading for the last 2.5hrs
08:48 PM Tom_L: robotustra stay away from the S8, i don't like their raised screen
08:48 PM Tom_L: and you can't get protective covers for it, they don't stay on
08:49 PM Tom_L: don't have much to say about apple except umm, they're kinda fruity
08:58 PM robotustra: I'm looking for standard 5" screen
09:07 PM Wolf__: current phone that bad?
09:07 PM Wolf__: just replace the screen
09:16 PM robotustra: I ordered the screen but it will come like in a 2-3 weeks
09:17 PM Tom_L: no shops around that replace them?
09:17 PM robotustra: and it was 2 years old, so may be it's time for new one
09:17 PM Tom_L: meh
09:17 PM Tom_L: i like my old one
09:17 PM robotustra: I think the screen in canada will cost like 2-3 time more
09:18 PM Tom_L: that's standard procedure up there
09:18 PM robotustra: I'm thinking I can do some experiments with firmware when the screen arrive
09:18 PM robotustra: it was redimi 3
09:19 PM CaptHindsight: https://www.gsmarena.com/xiaomi_redmi_3-7862.php
09:20 PM robotustra: the battery swelled and cracked the screen, I tried to unglue it and cut the harness :(
09:20 PM robotustra: the problem is that I can't find the phone of the same size
09:20 PM robotustra: 5" is ideal
09:21 PM robotustra: but now all produce phones wider and longer, and I hate the size
09:21 PM CaptHindsight: robotustra: what service provider do you have?
09:22 PM robotustra: telus
09:22 PM robotustra: I didnt got this phone from provider, I got it from china directly
09:23 PM robotustra: it worked ok for 2+ years
09:23 PM CaptHindsight: https://www.gsmarena.com/samsung_galaxy_s5-6033.php ~$200 and replaceable batter
09:23 PM CaptHindsight: y
09:24 PM robotustra: no, 2800 mah
09:24 PM robotustra: xiaomi had 4000 mah
09:25 PM CaptHindsight: yeah but it was built in
09:25 PM CaptHindsight: and overheated
09:25 PM robotustra: no
09:25 PM robotustra: I'm not sire if it was overheat
09:25 PM CaptHindsight: "the battery swelled and cracked the screen"
09:26 PM robotustra: it's cracked only when I started to unglue it
09:26 PM CaptHindsight: they don't swell at ~20C
09:26 PM Wolf__: over charge or over discharge
09:26 PM robotustra: so, I'm guilty, not battery
09:27 PM Wolf__: lion usually dont self inflate for no reason
09:27 PM robotustra: it's not drammatically swelled
09:27 PM robotustra: I think I kept it on the charger too often
09:27 PM Kevin`: phone manufacturers overcharge their batteries significantly because it gives extra capacity and fewer charge cycles. both desirable.
09:27 PM CaptHindsight: anyway, the galaxy s5 is ~$200, replaceable battery, runs on your network and is easily rooted and runs ...
09:28 PM robotustra: there are plenty of unloked devices in here
09:28 PM robotustra: for 200
09:28 PM robotustra: even new ones
09:28 PM robotustra: but I'm not sure I want xiaomi redmi again
09:29 PM robotustra: my price tag is 200-250 cad
09:30 PM robotustra: I was trying to understand the diff between wiaomi mi, redmi, note modifications
09:30 PM robotustra: don't see much difference
09:30 PM robotustra: all rins qualcomm cpu
09:30 PM robotustra: run
09:31 PM CaptHindsight: ... Lineage https://lineageos.org/
09:33 PM robotustra: and one more thing which CPU is better: MTK6762 or Snapdragon
09:33 PM Wolf__: my suggestion https://i.imgur.com/Q4OvRY0.jpg
09:34 PM robotustra: I would buy it, but telus CDMA does not run in canada since 2016
09:35 PM Wolf__: lol
09:35 PM robotustra: that's why I was forced to buy this first smatphone
09:35 PM robotustra: it's absolutely true
09:35 PM robotustra: how tech companies force you to buy shit
09:36 PM Wolf__: yup, but that alpha is ’95 tech lol
09:37 PM robotustra: what frequency?
09:37 PM robotustra: does it work?
09:37 PM Wolf__: I have no idea
09:37 PM Wolf__: hard part might be getting battery for it, original were Ni-Cad lol
09:40 PM Wolf__: specs are in these photos http://www.mobilecollectors.net/phone/3802/Motorola+MicroTAC+Alpha
09:41 PM Wolf__: 832/2412mhz
09:53 PM robotustra: ok, topic is closed
09:53 PM robotustra: got redimi 5 for 209 cad before tax
09:54 PM robotustra: hope this topic is closed for at least 2+ years :)
09:56 PM Wolf__: :)
09:59 PM robotustra: does anybody tried to use smartphone dislay+touchscreen as a second display for linux?
09:59 PM roycroft: huh?
09:59 PM CaptHindsight: fof CNC while at the beach? :)
09:59 PM CaptHindsight: fof/for
09:59 PM roycroft: if you're talking about a smartphone with a 15" display that might be tolerable
10:01 PM Wolf__: like DRO and spindle would be kinda ok
10:01 PM roycroft: young whippersnappers and their good vision
10:01 PM Wolf__: lol
10:04 PM robotustra: no, I'm talking about 5" display :)
10:04 PM robotustra: may lathe is tiny, it needs a tiny display :)
10:04 PM roycroft: that's big enough for an e-stop button
10:04 PM robotustra: yes
10:05 PM robotustra: if the display will be within 2-3 feets it's ok
10:09 PM robotustra: I mean is it theoreticaly possible to use smartphone as a second display?
10:09 PM robotustra: well, I'll google
10:09 PM Wolf__: everything is possible
10:10 PM Wolf__: worth fighting with stuff to get it to work on the other hand…
10:10 PM roycroft: this is kind of interesting:
10:10 PM roycroft: https://eugene.craigslist.org/tls/d/johnson-model-bandsaw/6664140493.html
10:10 PM roycroft: 10x18
10:11 PM roycroft: it looks like it needs some tlc
10:11 PM robotustra: oh
10:11 PM roycroft: but it would be a nice upgrade to my 7x12
10:11 PM roycroft: if i can make the room for it
10:11 PM robotustra: https://www.spacedesk.net/features/
10:11 PM robotustra: it looks like it was done already
10:12 PM Wolf__: windows
10:12 PM robotustra: there are any other options
10:12 PM Wolf__: for the display
10:13 PM Wolf__: windows only for the server
10:16 PM robotustra: spacedesk is not the only program that exists

11:13 PM flyback: https://www.youtube.com/watch?v=bRl0ztxn094\
11:29 PM hazzy-lab: flyback: that is pretty neat
11:36 PM Wolf__: hmm, how much head and water flow do I need to do that? =)
11:52 PM flyback: Wolf__, depends on the scale
11:53 PM Wolf__: 2-3hp worth of 3phase 220? =)
11:54 PM flyback: you will need an exciter
11:54 PM flyback: small generator or something or charged caps to get the field initially energized
11:54 PM flyback: and you need to disconnect the load before it spins up
11:54 PM flyback: otherwise induction motors as generators are fine
11:54 PM Wolf__: so, not as simple as just spinning a 3phase motor is it
11:55 PM flyback: well almost it's just it won't self generate so you need to energize the field
11:55 PM flyback: could be a battery and a cheap inverter even
11:55 PM flyback: once it's charged it stays charged unless overloaded or stopped
11:56 PM Wolf__: ok
11:56 PM flyback: it's not hard
11:56 PM flyback: don't panic
11:56 PM flyback: commercial generators have the same issue
11:56 PM flyback: so they had these little motor looking things on the side
11:56 PM flyback: called exciters
11:57 PM Wolf__: cool
11:58 PM flyback: it would be a perm magnet dc motor or such to get the magnetic field going
11:58 PM flyback: since it's only used during stop/starts, the brush life is not a concern
11:59 PM flyback: some don't use brushes and have spinning diodes
11:59 PM flyback: https://tcluk.net/Zambia-Static-Excitation-System
