12:46 AM miss0r2: Back :]
12:46 AM gloops: 'bought by a clockmaker who has sadly passed away' - i always think of archivist when i see ads like that..:/
12:46 AM fragalot: miss0r2: you're late!
12:46 AM miss0r2: lol you got here 20 minuts ago...
12:46 AM miss0r2: I was down here at 01:00
12:46 AM miss0r2: I just got back from the anodizing place
12:46 AM miss0r2: so STFU and get me some coffee :D
12:46 AM fragalot: no, this one is mine
12:46 AM * miss0r2 growls from the pit of his stomach
12:46 AM miss0r2: meh... it'll be cold before it gets here anyway :)
12:46 AM miss0r2: I just have to make 8 small brackets. I had to abandon the idea to get those anodized as well.
12:46 AM fragalot: I mean if I need to bring it I'd still need to shower & get out of my jammies
12:47 AM miss0r2: can't wait to see how well they look once I get them back from anodizing. surprisingly cheap
12:47 AM fragalot: uh oh :P
12:47 AM miss0r2: even with a rush fee it only amounts to 110eur
12:47 AM fragalot: that's not bad
12:48 AM miss0r2: Indeed. I would not have been surprised if it was double or triple that
12:48 AM fragalot: I made the mistake once to get parts hard anodised instead of just anodised
12:48 AM fragalot: now THAT is expensive.
12:48 AM miss0r2: how expensive?
12:48 AM miss0r2: perhaps that is what I should've done :D
12:48 AM fragalot: 250 / part
12:48 AM miss0r2: ouch
12:49 AM miss0r2: glad I didn't ask for that :D
12:49 AM fragalot: soft anodising was 50 / part
12:49 AM miss0r2: soft anodising is still rather hard :)
12:49 AM Wolf__: wtf is the process that much different
12:49 AM Wolf__: or they just charge premium for it
12:49 AM miss0r2: isn't it just the thickness?
12:49 AM fragalot: Wolf__: no idea
12:50 AM fragalot: miss0r2: yea but I don't know how fast the layer thickness grows, or if it's one of those logarithmic things
12:50 AM miss0r2: I'm also surprised at how fast they are; I dropped the parts off at 6:45 and they will be ready at 11:00
12:51 AM fragalot: plenty of time for you to make those 8 brackets & get those anodised too
12:51 AM fragalot: :D
12:51 AM miss0r2: hmm... That would make sense, as anodized aluminium is electrically insulated.
12:51 AM miss0r2: so I guess they would have to increase the voltage ALOT during the process
12:51 AM miss0r2: even more so with the ticker layer
12:52 AM miss0r2: hehe, they close at noon today, so that is out of the question
12:52 AM fragalot: guess they'll have to anodise naturally :D
12:53 AM miss0r2: I've got a sharpie...
12:54 AM fragalot: hehe
12:54 AM fragalot: at the very least botch them up by DIY powdercoating
12:55 AM miss0r2: hehe, they will get a smooth sanding - the end.
12:55 AM miss0r2: I can always make a new batch, and have that anodized
12:56 AM miss0r2: I'm going for the 'dropped on the shop floor and kicked around"-look
12:57 AM fragalot: that's about 220 grit?
12:58 AM miss0r2: have you seen my floor? at places its a 1 grit
12:59 AM fragalot: hehe
12:59 AM fragalot: i'm off -- ttyl
01:47 AM gloops: https://www.ebay.co.uk/itm/10pcs-Solid-Carbide-Double-Two-Flute-Spiral-Cutter-3-175x32mm-CNC-Router-Bits/232780204620?
01:47 AM gloops: 32mm seems a bit long for a 3mm bit..
01:56 AM Loetmichel: why?
01:56 AM Loetmichel: works fine in carbide and alu
01:56 AM Loetmichel: but i doubt those bits are ground properly
01:57 AM Loetmichel: friend bought some with the same looks. turned out that they have no proper "center cut" tip. so they were useless for plunging
01:58 AM gloops: 32 mm cutting depth, ive got 22mm which are fine, 32mm though think theres gonna be some bend in the tool if its cutting with any speed or depth
01:58 AM gloops: useful though if you need it
01:59 AM Loetmichel: gloops: thats why i said: fine if carbide
01:59 AM Loetmichel: a HSS tool would certainly bend
01:59 AM Loetmichel: a carbide tool works
02:00 AM Loetmichel: been there done that
02:00 AM Loetmichel: (at least in wood and alu, never tried steel)
02:00 AM gloops: ive bought some anyway lol
02:00 AM gloops: would have preferred 1 flute though
02:16 AM Deejay: moin
02:22 AM gloops: morning
02:31 AM pink_vampire: morning
02:36 AM Loetmichel: *HIHIHIHI* coworker just complaining that the EMI measurement chamber has a very "dirty" "empty measurement"... so we got searching: turns out the notebook that sits OUTSIDE the chamber somehow produces emi when running on mains. Solution: take a garden waterin can and pour 20 liters of water down the chambers (own) earthing rod. Al "dirt gone". $me is making a work sheet to put on the
02:36 AM Loetmichel: chamber wall: "every two weeks: watering the earthing rod!" ;)
02:45 AM pink_vampire: Loetmichel: here we have rain / snow every few days to make sure the earthing rod s are in a geed shape
02:50 AM Loetmichel: pink_vampire: thats a seperate earthing rod JUST for the measurement chamber, drilled thru the concrete floor in the middle of the company
02:51 AM Loetmichel: it doesent get that much rain/snow from the outside
02:58 AM Loetmichel: the company has about 1000 square meters on the ground floor
02:58 AM Loetmichel: and its pretty much centered
03:07 AM pink_vampire: any pics of it?
03:10 AM Loetmichel: i have now. but there is not much to see: http://www.cyrom.org/palbum/main.php?g2_itemId=17310&g2_imageViewsIndex=1
03:10 AM Loetmichel: @ pink_vampire
03:11 AM pink_vampire: this is just amazing!
03:13 AM Loetmichel: its just a 200mm hole in the concrete and a long earthing rod hammered into it
03:13 AM Loetmichel: 5m long iirc
03:13 AM Loetmichel: then connected to the chamber and capped with a waste pipe cap
03:15 AM Deejay: lol
03:16 AM pink_vampire: sometimes the simple stuff work the best
03:16 AM Loetmichel: needs occasional watering it seems though
03:16 AM Loetmichel: so not working "best" ;)
03:16 AM Loetmichel: Deejay: whats so funny?
03:17 AM Deejay: never seen something like that
03:17 AM pink_vampire: drill it deeper to the aquifer layer
03:17 AM Wolf__: dry dirt doesnt conduct very well, had that problem when I was working doing under ground street light cable repair
03:18 AM Loetmichel: Wolf__: indeed
03:18 AM Loetmichel: its just a secondary earth though
03:18 AM Wolf__: no conduction to ground and its now a antenna lol
03:19 AM Loetmichel: the company power supply has the (in germany) usual 30mm wide steel band wound around the whole foundation for earth.
03:19 AM Loetmichel: Wolf__: exactly ;)
03:19 AM Wolf__: o thats neat, they dont do that here
03:21 AM Wolf__: finding broken/faulted wires underground was a sorta fun interesting job
03:28 AM Loetmichel: Wolf__: german houses use basically 3 types of earthing: steel band IN the foundation slab, earthing rods orr a steel band thrown around the slab into the excavation after the foundation is poured: http://www.elektrohamann.de/knowhow/images/antennenblitzschutz/bild5.jpg
03:28 AM Loetmichel: either the "fundamenterder" or the "banderder" are the usual here in germany
03:28 AM Wolf__: actually, I dont know if they do the band type here or not
03:29 AM Loetmichel: the rod is only done for refits of old houses
03:32 AM Loetmichel: and the steel band around the house is usually preverable to the "in concrete" earthing because it runs parallel to the foundation drainage and is usually always wet enough to work well
03:32 AM Wolf__: yeah
03:32 AM Loetmichel: preferable
03:33 AM Wolf__: my house was built before electric existed lol
03:34 AM Loetmichel: fun fact: just noticed while searcing for pictures for you that they seem to have swtiched from zinced steel bands to stainless since i worked in construction .-)
03:34 AM Loetmichel: back when i did that kind of stuff ('90s) it was mostly 30mm wide 5mm thick steel zinc plated
04:45 AM jthornton: morning
04:49 AM XXCoder: hey jthornton you ever play myst game?
04:50 AM jthornton: no
04:50 AM XXCoder: me neither lol loved the books tho so I supported kickstarter
04:50 AM XXCoder: I just got linking book. yay
04:50 AM XXCoder: video is amazing
04:52 AM CNC_Brian: Anyone alive?
04:53 AM XXCoder: nah im zombie
04:53 AM XXCoder: I think pink_vampire is actual vampite so undeafd
04:53 AM XXCoder: jthornton might be also zombie.
04:53 AM jthornton: I arise from the dead very early
04:53 AM CNC_Brian: Just migrating a config with a mesa card in it from 2.7 to 2.8
04:53 AM Deejay: welcome to the black mesa transit system
04:54 AM CNC_Brian: Been pulling my hair out as it cant fine axis.0.
04:54 AM XXCoder: give linuxcnc fines sheet it should be able to fine axis.0 ;)
04:54 AM XXCoder: odd though
04:54 AM CNC_Brian: Loaded config by hand with halrun and seems the axis are not numbered anymore but have leterd
04:54 AM jthornton: did you run the 2.7 configuration in 2.8?
04:54 AM CNC_Brian: Axis.a.
04:55 AM jthornton: use the configuration update wizard
04:55 AM CNC_Brian: Trying to magrate an existing
04:55 AM CNC_Brian: I like doing things by hand as I learn more
04:55 AM jthornton: I'm trying to tell you how to migrate... run it in 2.8
04:56 AM CNC_Brian: Is there a doc on what the wizard will do?
04:56 AM jthornton: you end up with the old and the new then you can compare them
04:56 AM jthornton: no, nothing you would have to read the code
04:56 AM CNC_Brian: Is it in the scripts folder?
04:57 AM jthornton: dunno you might grep for 1.1 as it checks the ini version on load every time and if it is not 1.1 it triggers the converstion
04:57 AM jthornton: I don't care for the way it works I think it should be a menu item myself
04:58 AM CNC_Brian: Where is the update wizard living?
04:58 AM jthornton: dunno, you will have to search for it
04:59 AM jthornton: you might start with the linuxcnc script
04:59 AM CNC_Brian: Ok thanks, I will have a look. Just glad Im not going mad
05:00 AM jthornton: now why in the heck does github think my 7i76e converstion tool is in pascal???
05:01 AM CNC_Brian: Sounds like we are all having a good day
05:01 AM CNC_Brian: Never had all these problems with a good old hammer and chisel
05:02 AM jthornton: just purple finger nails...
05:08 AM jthornton: damn zip file full of bit files made github think I wrote in pascal... on to the next challenge
05:12 AM jthornton: ok travis it building the docs for the 7i76e tool
05:13 AM jthornton: and it passed yippie
05:16 AM Tom_L: something good happen already this morning?!
05:17 AM Tom_L: 35°F Hi 50
05:17 AM Tom_L: all the frozen is turning to mud...
05:18 AM XXCoder: frozen car is turnbing to mud?
05:19 AM jthornton: it will be mud around here by Saturday lol 100% chance of rain tomorrow
05:19 AM pink_vampire: https://youtu.be/c2FY0xLwAcw
05:19 AM Tom_L: it sprinkled a little last night but not very much
05:19 AM jthornton: high today 44Â°F low tonight 44Â°F
05:19 AM XXCoder: jt btw had snow yeserday, didnt last but there was still olllld snow with new snow on it LOL
05:19 AM XXCoder: sure turned it white again
05:23 AM jthornton: nice to look at sometimes if you don't have to drive in it
05:23 AM XXCoder: yeah
05:58 AM jthornton: http://gnipsel.com/images/house/1-19-19.jpg
06:01 AM XXCoder: heh getting to dusk eh
06:01 AM XXCoder: or very early morning
06:03 AM jthornton: I think very overcast
06:13 AM CNC_Brian: Is is possible to integrate the mesa-hostmot2 from 2.8 into 2.7? Need or would like mesa 7i96 in 2.7
06:14 AM jthornton: 7i96 requires master
06:14 AM XXCoder: overcast could do that yeah
06:14 AM jthornton: CNC_Brian: having problems converting your configuration?
06:17 AM CNC_Brian: Yes, Got all the axis and joint swapped over but now its moaning about. emcTrajSetJoint failing
06:17 AM CNC_Brian: Cant fine the update wizard
06:19 AM jthornton: just let it do it's thing and convert your configuration
06:20 AM CNC_Brian: I cant find the wizard to convert
06:20 AM CNC_Brian: Or do I just run 2.8 with a 2.7 config?
06:22 AM jthornton: you don't find the wizard you just try and run your configuration and it finds you
06:22 AM jthornton: yes
06:22 AM jthornton: just run your configuration with version not being 1.1
06:22 AM CNC_Brian: ahhhh
07:29 AM Loetmichel: hmm, anyone an idea what that writing meant before the chip exploded? also where to get that chip or a function compatible one? my lathe lamp PSU just exploded... :( -> http://www.cyrom.org/palbum/main.php?g2_itemId=17313&g2_imageViewsIndex=1
07:32 AM pink_vampire: 11K61400
07:48 AM Jymmm: Loetmichel: Take another photos from a different angle
07:53 AM Loetmichel: The other channels say LNK614DG... seems to fit. i'll see where to get that thing. thanks anyways!
07:54 AM Jymmm: Loetmichel: https://www.digikey.com/product-detail/en/power-integrations/LNK614DG-TL/596-1728-1-ND/9326579
10:05 AM CNC_Brian: Anyone know where the source for linuxcnc.so live on github
10:10 AM pink_vampire: mmm
10:10 AM pink_vampire: let me see
10:11 AM pink_vampire: https://github.com/LinuxCNC/linuxcnc
10:11 AM CNC_Brian: Im just in the master branch, want to have a look at the code forms the python module linuxcnc.so
10:12 AM CNC_Brian: Down understand the architecture very well lf at all.
10:15 AM mozmck: Some of the file locations are not intuitive. I think it's mostly because the project has been around a long time now and changed and morphed over time.
10:16 AM CNC_Brian: Im not a c programmer so its all a bit confusing.
10:16 AM mozmck: I think the file you want is: src/emc/usr_intf/axis/extensions/emcmodule.cc
10:17 AM CNC_Brian: Wow I would never have found that
10:18 AM mozmck: yeah, like I said...
10:18 AM mozmck: I believe it's there because it was written for the Axis UI originally.
10:19 AM CNC_Brian: That defo the file I need. Seems to have been some changed in this since 2.7 so my python UI is throwing a wabbler
10:40 AM jthornton: can you translate my python UI is throwing a wabbler into english?
10:44 AM CNC_Brian: Causing a traceback?
10:45 AM jthornton: what is the error? if it's long please use paste.ubuntu.com
10:48 AM CNC_Brian: Im polling linuxcnc.status
10:51 AM CNC_Brian: And it used to return a G_GCODE_ORIGIN, but the code seems th think its not anymore
10:51 AM jthornton: hmm let me look
10:51 AM CNC_Brian: Think the linuxcnc.so is just a shim and the data comes from deeper in
10:51 AM jthornton: I don't see G_GCODE_ORIGIN anywhere in 2.7 or 2.8 are you sure of this?
10:52 AM jthornton: your not using gommpappy are you?
10:54 AM CNC_Brian: No its some code I wrote 3 years ago, haven't touched it since.
10:55 AM jthornton: you might grep for G_GCODE_ORIGIN to see where it is
10:57 AM jthornton: src/emc/nml_intf/emc.hh has most of the lcnc constants and a few are in motion_types.h
10:58 AM CNC_Brian: thanks
10:59 AM jthornton: if your not familiar with grep I've found grep -irl 'search term' * to be most effective
11:02 AM CNC_Brian: Looks like its just want I have called the field returned when I poll linuxcnc.status
11:09 AM fragalot: 'sup
11:19 AM fragalot: oh dear
11:19 AM fragalot: customs boss man in belgium has kindly asked belgian companies to postpone any shipments to the UK after march 29th until things get cleared up
11:19 AM fragalot: or ship extra stock prior to that date
11:21 AM gloops: i didnt realise we bought anything from Belgium
11:26 AM Loetmichel: hihi, i think my wife watches to much GoT... just came home, looked at the TV before greeting my wife, couldnt hold a "You know nothing, John Snow!" in. Then asked "or wasnt that the guy?". Wife: "sure it was." And thats just by glimpsing at the screen whenever i walk by the living room for a smoke ;)
11:26 AM Jymmm: Does anyone know what most garage door open CONTROL voltage is? Like when there is a 2 wire illuminated button
11:26 AM Jymmm: s/open/opener/
11:29 AM fragalot: Jymmm: really depends on the make
11:32 AM Jymmm: fragalot: Yeah, but I'm tryiing to figure out how they use two wire to illuminate the wall switch, yet "short" the pair to open/close the door.
11:33 AM Jymmm: I believe the 3 buton wall switch just adds a resistor,
11:33 AM fragalot: don't they use an AC voltage?
11:34 AM CNC_Brian: Doesn't the light go out when the switch isn on?
11:34 AM Jymmm: The RC pcb uses dc
11:34 AM Jymmm: CNC_Brian: Not the celiling light, an illuminated button
11:34 AM fragalot: could be a simple current sense circuit
11:34 AM Jymmm: fragalot: I'm thinking that. What I REALLY want is to tap into the power
11:35 AM fragalot: or current limited output & just shorting it to gnd
11:35 AM fragalot: Jymmm: i guess you'll just have to pull out your multimeter & find out then :D
11:35 AM fragalot: see how much you can draw before it trips
11:36 AM Jymmm: lol, not that much, just a uC.
11:36 AM Jymmm: If anyoen has an idea on a sensor to determine the door's actual position (not just open/closed) ???
11:37 AM fragalot: there are many options for that
11:37 AM SpeedEvil: Jymmm: Spindle encoder.
11:37 AM fragalot: ultrasonic is a popular one
11:37 AM fragalot: encoders are more accurate
11:37 AM fragalot: or a resolver if you're feeling fancy :D
11:37 AM Jymmm: SpeedEvil: I was thinking that. But how? where?
11:38 AM SpeedEvil: Mount it on the axis.
11:41 AM Jymmm: Hmmm
11:44 AM Jymmm: Dis this (schematic and caps he speaks of) make sense??? https://www.dslreports.com/forum/r28474398-Two-wire-multi-function-garage-door-control
11:45 AM Jymmm: Does*
12:35 PM gregcnc: how much resolution does a garage door need? What about the limit switches in the opener already?
12:39 PM gloops: he might want to leave it open high enough for the cat to get in, but not a person
12:42 PM gregcnc: eh I didn't read enough
12:43 PM pink_vampire: https://i.imgur.com/JVTHCGW.png the new wire duct in place, and some of the new wiring
12:48 PM JT-Shop: looking good
12:49 PM gloops: looks very pro
12:53 PM roycroft: my garage door opener has limit switches at both ends of the track
12:53 PM roycroft: they're pretty darn accurate
12:54 PM roycroft: if i set the door closed limit switch a couple mm too far the door will hit the floor and open back up because it thinks it hit something that it shouldn't
12:56 PM roycroft: and a cat only needs an opening about 1/10 as high as the thickness of its head to squeeze through, so it can close almost all the way and still let the cat in
12:56 PM roycroft: i don't know how cats do that - it must be part of cat magic
12:56 PM pink_vampire: i need to re wire all the bottom part
12:57 PM roycroft: i do know that they're only able to squeeze through an opening that's physically impossible for them to go through when you don't want them to
12:57 PM roycroft: if you want them to they won't fit
12:57 PM pink_vampire: the label printer work hard
01:39 PM gloops: 8ft table, 20mm ballscrews..ah https://www.facebook.com/bill.srmllc/videos/3113506965344676/
01:40 PM gloops: surely they must think of doing some research before going to all that trouble and expense
01:42 PM pink_vampire: The link you followed may have expired,
01:44 PM gloops: ahh, well just a saggy shakey ballscrew thats all lol
01:51 PM Jymmm: gloops: lol
02:29 PM JT-Shop: dang 50 bucks for a new fill valve on the 500 gallon tank
03:17 PM SpeedEvil: 3d print one.
03:23 PM JT-Shop: printer is broken
03:24 PM pink_vampire: JT-Shop: https://i.imgur.com/GaLNwEA.png
03:26 PM JT-Shop: almost done I see
03:26 PM SpeedEvil: pink_vampire: have you considered macrame?
03:27 PM pink_vampire: why do you say that?
03:51 PM gloops: typical, ask the mrs to go to the shop for a mars bar, she come back with 5 carrier bags loaded
03:55 PM JT-Shop: full of mars bars?
03:57 PM gloops: no only 5 mars bars lol
03:59 PM SpeedEvil: My supermarket made an error repricing and I ended up with 5 carrier bags of mars bars.
03:59 PM SpeedEvil: (well, assorted candy really)
03:59 PM gloops: that wouldnt be bad at all
03:59 PM SpeedEvil: They intended to reprice to 90% of the price of a 12-pack.
03:59 PM SpeedEvil: they instead repriced the 12-pack to 90% of the price of 1 bar.
04:00 PM gloops: if its priced they have to sell it for that
04:00 PM gloops: i mean if there is a price on it
04:23 PM Deejay: gn8
05:06 PM andypugh: Damn â€śThis Old Tonyâ€ť he made me want to buy some cold blueing liquid.
05:06 PM andypugh: Though I have to admit the results are good.
05:07 PM x2s: But don't get the cheapest one off ebay ;)
05:07 PM andypugh: The â€ścheapest off eBay.co.ukâ€ť isnâ€™t especially cheap.
05:07 PM XXCoder: lol damn he cost you money eg ;)
05:07 PM andypugh: And is what I got.
05:07 PM XXCoder: any good?
05:08 PM andypugh: Yes.
05:08 PM andypugh: Very pleased, actually.

05:10 PM Tom_L: andypugh did you get your drive enable working?
05:11 PM andypugh: Yes. I used a USB cable and a DC-DC converter to source 24V
05:12 PM XXCoder: cool. i doubt i will mill steel and stuff as hard at home lol
05:12 PM XXCoder: mostly wood and maybe alum and plastics
05:14 PM Tom_L: curious if they air the Grand Tour in UK since they got in trouble
05:15 PM SpeedEvil: https://www.alibaba.com/product-detail/High-Purity-Industrial-Grade-Selenium-Dioxide_50039539187.htm
05:15 PM SpeedEvil: Tom_L: They didn't get into trouble.
05:16 PM Tom_L: clarkson got fired
05:16 PM SpeedEvil: A company stopped producing their show.
05:16 PM Tom_L: and they all went with him
05:16 PM SpeedEvil: BBC would never typically air any non-BBC (co) productions anyway.
05:17 PM SpeedEvil: There are several other UK terrestrial broadcasters, any of which could ahve boght the rights. And of course you can watch it on amazon
05:45 PM gloops: selenium is what they used for a 'battery' in old camera light meters
05:45 PM gloops: anyway bedtime here
05:57 PM XXCoder: SpeedEvil: your url is missing a l
05:58 PM SpeedEvil: oops
06:00 PM XXCoder: wow my myst linking book come with bunch of files, cool but one of em is gehn's logo in grayscale.
