12:17 AM pink_vampire: is there a way to do math in pyvcp?
01:47 AM fdarling: pink_vampire: what do you mean by "do math"? Like have a formula to calculate a displayed number?
01:47 AM pink_vampire: correct
01:47 AM pink_vampire: yeah
01:47 AM fdarling: pink_vampire: that example I gave you of the velocity in units per minute was scaling by 60
01:48 AM fdarling: pink_vampire: I believe you have to "wire it up" in HAL, there isn't a way to have it evaluate a math expression directly
01:49 AM pink_vampire: i just want to divide in 360
01:49 AM pink_vampire: fdarling: ^
01:50 AM fdarling: pink_vampire: http://linuxcnc.org/docs/html/man/man9/scale.9.html
01:51 AM fdarling: pink_vampire: that's what I used to multiply by 60.0, instead you can multiply by 1.0/360.0 = 0.00277777, it might have rounding errors of course
01:52 AM pink_vampire: now i have that to convert mm/s to mm/min setp scale_vel.gain 60
01:52 AM fdarling: the "loadrt scale names=scale_vel"
01:52 AM fdarling: you'd add more names
01:53 AM fdarling: loadrt scale names=scale_vel,div_angle
01:53 AM fdarling: setp div_angle.gain 0.00277777
01:53 AM fdarling: and use the net command to wire up the inputs and outputs to your appropriate things
01:54 AM pink_vampire: I added scale_rpmc
02:06 AM pink_vampire: i'm getting an error
02:06 AM pink_vampire: custom_postgui.hal:96: Pin 'axis.5.joint-vel-cmd' was already linked to signal 'disp-velocity-per-second-z'
02:07 AM pink_vampire: fdarling: ^
02:07 AM fdarling: show me all lines dealing with 'disp-velocity-per-second-z'
02:09 AM pink_vampire: https://paste.debian.net/plain/1075459
02:10 AM pink_vampire: fdarling: i just tried to use the same c axis hal pin to display deg/min and also rpm
02:12 AM fdarling: pink_vampire: the second time you omit the axis.5.join-vel-cmd
02:12 AM fdarling: pink_vampire: with the net command you are saying what is attached to a "signal" name
02:13 AM pink_vampire: correct
02:13 AM fdarling: pink_vampire: read up on the net command
02:13 AM fdarling: http://linuxcnc.org/docs/2.5/html/hal/basic_hal.html#_net_a_id_sub_net_a
02:15 AM pink_vampire: so i need to i need to split the "signal source" with "signal"??
02:16 AM fdarling: pink_vampire: just do net SIGNALNAME => OUTPUT_PIN
02:16 AM fdarling: pink_vampire: if you already hooked up the netto INPUT_PIN, don't do it again
02:17 AM pink_vampire: so how i can split it??
02:17 AM fdarling: net disp-velocity-per-second-z axis.5.joint-vel-cmd => scale_velz.in
02:17 AM fdarling: net disp-velocity-per-second-z => scale_velc.in
02:17 AM fdarling: that simple
02:18 AM fdarling: maybe this makes it more clear:
02:18 AM fdarling: net disp-velocity-per-second-z <= axis.5.joint-vel-cmd
02:18 AM fdarling: net disp-velocity-per-second-z => scale_velz.in
02:18 AM fdarling: net disp-velocity-per-second-z => scale_velc.in
02:18 AM fdarling: make sense?
02:20 AM pink_vampire: so disp-velocity-per-second-z is the main "pipe" and the axis.5.joint-vel-cmd is just the raw input?
02:20 AM fdarling: net command makes a "signal" that can have a value if it doesn't exist, otherwise it hooks things to it that can output onto or read from it
02:21 AM fdarling: (I honestly don't know how it deals with bidirectional pins and multiple people writing to the same signal)
02:21 AM fdarling: but conceptually it's like a "wire"
02:21 AM fdarling: except it can have direction (at least for reading purposes)
02:22 AM fdarling: if you read that "net" web page I showed you, it says that the net command actually ignores the arrows
02:22 AM pink_vampire: it is say it is not exist
02:23 AM fdarling: hmm?
02:23 AM pink_vampire: i'm trying again
02:26 AM pink_vampire: i found the problem
02:26 AM pink_vampire: i did
02:26 AM pink_vampire: net disp-velocity-per-second-c disp-velocity-per-second-z => scale_velc.in
02:26 AM pink_vampire: so i remove
02:26 AM pink_vampire: net disp-velocity-per-second-z axis.5.joint-vel-cmd => scale_velz.in
02:26 AM pink_vampire: and
02:26 AM pink_vampire: net disp-velocity-per-second-c disp-velocity-per-second-z => scale_velc.in
02:27 AM pink_vampire: and replaced them with your lines, and now it is work!!
02:28 AM pink_vampire: fdarling: thanks!!
02:39 AM fdarling: does anyone have any USB WiFi dongle recommendations that have proper antennas?
02:47 AM pink_vampire: here is all wired
02:48 AM XXCoder: fdarling: lots cheap ones at aliexpress
02:48 AM fdarling: XXCoder: I would like a specific chipset or link to an Amazon product
02:49 AM XXCoder: yeah can look up models on google see which has specific chipset you want. ones that has model #s anyway
03:10 AM Loetmichel: *SPIT* *BAAAHHH* JB-weld(epoxy putty) swarf from filing it in the coffee... thats happens when you drink your morning coffee at the workdesk :-(
03:12 AM pink_vampire: with all the stuff that happen to you i think it's a miracle that you are still alive
03:14 AM Loetmichel: its not like its deadly
03:14 AM Loetmichel: it just tastes and smells horribble
03:17 AM Deejay: moin
03:33 AM XXCoder: lol https://www.youtube.com/watch?v=X1pB6O6AYMU
03:34 AM pink_vampire: lollllllllllllllll
03:36 AM pink_vampire: we need more humor like that
03:52 AM XXCoder: I read about laura ingraham... she said transgender is trying to make new species... uh does she not know how babies is made?
03:52 AM XXCoder: and new species? insane amount of work lol
04:29 AM jthornton: morning
04:30 AM XXCoder: hey jthornton
04:31 AM jthornton: what's up today
04:31 AM XXCoder: not a lot
04:36 AM jthornton: I have to be down at the industrial park at 7:30 to start a new machine up
04:39 AM pink_vampire: what machine?
04:39 AM XXCoder: yeah curius what machine heh
04:42 AM pink_vampire: i'm trying something
04:44 AM jthornton: it cuts the runners off some parts and indexes the boxes
04:52 AM XXCoder: wow amazing how far genetic engineering went. https://courses.cs.washington.edu/courses/cse154/17autemp/17sp/section/sect07/code/starter/regexhybrids/images/bird-eagle-horse.jpg
04:56 AM pink_vampire: this is soo cool
04:57 AM pink_vampire: I'm using one mouse with 2 usb dongles, on 2 computer!
05:30 AM Tom_L: morning
05:33 AM Tom_L: pink_vampire you should get twice as much done now
05:35 AM jthornton: morning
05:35 AM Tom_L: took a look at your GUI last night
05:36 AM Tom_L: pretty cool
05:36 AM jthornton: thanks
05:36 AM pink_vampire: hehe
05:36 AM Tom_L: your mdi may need an 'F' button
05:37 AM jthornton: it has a F button
05:38 AM Tom_L: i must have missed it
05:38 AM jthornton: G M T F on the left
05:38 AM Tom_L: ok
05:39 AM Tom_L: after messing around with installs all day you could have showed me just about anything and i'd believe it
05:40 AM XXCoder: including genetic pic i showed? heh
05:57 AM _abc_: Hello. Suggest best vm option to run the default wheezy-live-2.7 iso for testing?
05:57 AM _abc_: qemu / vbox / etc? Which one is least painful? In sim mode of course.
05:58 AM methods_: what host system?
05:58 AM methods_: for windows i'd say vmware
05:59 AM methods_: for *nix probably virtualbox
06:00 AM _abc_: linux host. Am using qemu-system-i386 now, it is okay but boot is slow.
06:01 AM _abc_: It can also do vmware, but is that not heavyer than qemu native? I mean qemu can do vmware.
06:14 AM methods_: if you're on linux i'd use virtualbox
06:15 AM methods_: but if you're more familiar with qemu i don't see why that wouldn't work
09:20 AM pink_vampire: is there a way to send a value from a gcode to pyvcp?
09:22 AM pink_vampire: i know about m68 but it is limited to 4 variables
09:43 AM fdarling: pink_vampire: what type of value?
09:44 AM pink_vampire: user defined variable #4454
09:44 AM fdarling: _abc_: VirtualBox hands down, VMWare performs a bit better but it's pay-for software
10:48 AM jthornton: pink_vampire: you can have up to 64 dio
10:48 AM pink_vampire: jthornton: how?
10:49 AM pink_vampire: it is E00-E03
10:49 AM pink_vampire: are you sure it is 64?
10:50 AM pcw_home: 64 in master
10:50 AM pcw_home: might be 16 in older versions
10:50 AM pink_vampire: what is master?
10:50 AM pcw_home: latest development version of LinuxCNC
10:51 AM pcw_home: in your hal file when you do "loadrt motmod" you can specify the number of aio and dio
10:51 AM pink_vampire: i'm with 2.7.8
10:52 AM pink_vampire: let me see
10:53 AM jthornton: http://linuxcnc.org/docs/2.7/html/config/core-components.html#sec:motion
10:53 AM jthornton: pink_vampire: ^^
10:54 AM pink_vampire: i don't even see it in my my-mill.hal file
10:57 AM jthornton: should be near the top of the file
10:57 AM jthornton: probably look like this loadrt [EMCMOT]EMCMOT base_period_nsec=[EMCMOT]BASE_PERIOD servo_period_nsec=[EMCMOT]SERVO_PERIOD num_joints=[KINS]JOINTS
10:58 AM pink_vampire: yes, that one i have
10:58 AM pink_vampire: but i dont have loadrt motmod
11:00 AM pcw_home: well you do but its a bit indirect
11:00 AM roycroft: welding folks: what kind of electrode would you recommend for gtaw welding mild steel?
11:00 AM roycroft: and i assume dc negative is the way to go with that
11:01 AM roycroft: i have some 2.0% thoriated and 1.5% lanthenated electrodes
11:01 AM pink_vampire: pcw_home: i'm not sure what do you mean,
11:02 AM roycroft: but i'll need to get different ones anyway, as all the electrodes i have are small, and i'll be welding on some thick-ish (3/8") steel
11:02 AM pink_vampire: do i need to replace the line in the file with the line from the linuxcnc doc?
11:03 AM jthornton: no
11:04 AM jthornton: https://paste.ubuntu.com/p/F9DGS6ZD6b/
11:04 AM jthornton: just add num_dio=how many you want to the end of the line
11:05 AM pink_vampire: is there a limit?
11:06 AM jthornton: 64
11:09 AM pink_vampire: https://paste.ubuntu.com/p/bKS5GDp6zv/
11:09 AM pink_vampire: the error and the line i did
11:09 AM pcw_home: What I mean is "loadrt motmod" is executed but its done via text macros from the ini file
11:10 AM jthornton: that's an analog pin, so it aio not dio... I thought you wanted digital pins sorry
11:10 AM jthornton: max 16 for aio
11:11 AM pink_vampire: i don't care digital or analog, it is just to sent a variable from the gcode to pyvcp
11:11 AM pink_vampire: is there a way to send digital pin from gcode?
11:11 AM pcw_home: digital is just a bit...
11:12 AM pink_vampire: i see
11:12 AM pcw_home: only "variable" from 0 to 1
11:13 AM pink_vampire: WORK!!!!!!!!!!!!!!!!!!
11:13 AM pink_vampire: i changed the dio to aio and from 64 to 16
11:13 AM jthornton: Awesome!!!
11:14 AM pink_vampire: what mcode send digital pin?
11:15 AM pink_vampire: M62 - M65 Digital Output Control ?
11:20 AM Lcvette: P#
11:23 AM Lcvette: pink_vampire: do you need analog inputs or outputs?
11:23 AM pink_vampire: for now - analog
11:24 AM pink_vampire: but i'm always have new ideas
11:24 AM Lcvette: what are you doing with them?
11:25 AM pink_vampire: send data to pyvcp from the gcode
11:25 AM fragalot: 'sup
11:25 AM Lcvette: with analog?
11:26 AM pink_vampire: correct
11:26 AM Lcvette: then looks like M68
11:26 AM pink_vampire: m68 E00 Q#1234
11:27 AM pink_vampire: 1234 is the variable
11:27 AM fragalot: anyone tried the new arduino port of linuxCNC that they released today?
11:27 AM pink_vampire: 00 is the analog number
11:27 AM pink_vampire: fragalot: look at the date
11:28 AM fragalot: pink_vampire: thanks for ruining it for everyone. :-)
11:28 AM Lcvette: so so then it would be M68 E0 Q#
11:29 AM Lcvette: or M68 E0 Q3
11:29 AM Lcvette: etc
11:29 AM Lcvette: don't use the leading zeros
11:30 AM pink_vampire: fragalot: i thought you didn't got the joke or something
11:31 AM pink_vampire: Lcvette: i think you need the 0
11:31 AM fragalot: pink_vampire: I just tried to think of the worst thing to say in this channel :P
11:31 AM Lcvette: no
11:31 AM pink_vampire: mmm ok
11:31 AM Lcvette: you do in the motion.analog
11:31 AM fdarling: pcw_home: hey, I am still running into that bug with LinuxCNC involving index homing, but in the process of debugging it I discovered a more serious issue (and resolved it)
11:31 AM Lcvette: but not in the gcode
11:32 AM fdarling: pcw_home: I had differential instead of single ended mode set in the jumpers for the Z-axis (I had forgotten to change it). I figured it out when the Z axis was "ratcheting" downwards to the table during jog tests after homing
11:32 AM pink_vampire: the manual say 00 01 02..
11:32 AM Lcvette: i use the M62-M65 alot in the ATYC remap
11:32 AM pink_vampire: what is atyc?
11:33 AM Lcvette: M68 E- Q-
11:33 AM Lcvette: from the manual
11:33 AM Lcvette: just like you don't use G01
11:33 AM Lcvette: you use G1
11:34 AM pink_vampire: motion.analog-in-00 - (float, in) These pins (00, 01, 02, 03 or more if configured) are controlled by M66. motion.analog-out-00 - (float, out) These pins (00, 01, 02, 03 or more if configured) are controlled by M67 or M68.
11:34 AM Lcvette: correct
11:34 AM Rab: fragalot, I hear that Mach4 is being reworked to incorporate a LinuxCNC core with a proprietary binary GUI. Newfangled Solutions is hoping to cut costs by leveraging the existing LinuxCNC support community. Pass it on.
11:35 AM Lcvette: configured the motion.analog with the leading zeros but not your gcode
11:35 AM fragalot: Rab: You win.
11:36 AM Lcvette: pink_vampire:
11:36 AM * Lcvette sent a long message: < https://matrix.org/_matrix/media/v1/download/matrix.org/DRvCGmGdouPEoKozAOCadYqy >
11:37 AM pink_vampire: yeah something like that
11:37 AM Loetmichel: Rab: would that be ok with the copyright that linuxCNC has?
11:37 AM Lcvette: ```
11:37 AM Lcvette: M64 P0 ; Move Carousel out
11:37 AM Lcvette: and that is from my subroutine
11:37 AM Loetmichel: or is that just april fools?
11:38 AM fragalot: Rab: see?
11:38 AM Lcvette: M64 P0, corresponds to the motion.digital-out-00 pin
11:39 AM pink_vampire: https://i.imgur.com/34vvnLi.png AWWWWWWWWWWWWWWWWWWWWWWWW
11:54 AM Rab: Loetmichel, sure, it's totally fine to ship GPL2 software along with proprietary junk. See: every DVD/BR player, smart TV, etc. I'm just trolling for April 1st, but I believe Tormach's PathPilot is literally what I described. ;)
12:04 PM * Jymmm takes away pink_vampire crayons, which happen to be all pink!!!
12:05 PM Loetmichel: Jymmm: go figure! ;)
12:05 PM pink_vampire: http://3.bp.blogspot.com/-tEkRWjKrz_Q/UQIgupuQptI/AAAAAAAAAho/JahENXk_obo/s1600/IMG_0678+all+the+pink+crayons.JPG
12:06 PM Jymmm: Loetmichel: The things is, pink_vampire had to have bought 64 sets of crayons to get an ALL PINK set, So, what did she do with all the rest???
12:06 PM Jymmm: pink_vampire: SMH
12:07 PM Loetmichel: Jymmm: eaten?
12:08 PM Loetmichel: ny crayon sets have "holes" in them. too
12:09 PM Jymmm: Loetmichel: She probably milled/cast them into lip shapes
12:10 PM Jymmm: Loetmichel: I know I'm going to regret posting this (gives pink_vampire ideas)... https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcRqOnj-0XDV8Lmaf89nKOg-OXA-jrGFMuPz6dALkAmcoruhQhbq
12:11 PM pink_vampire: diy machinable wax
12:11 PM Jymmm: Loetmichel: see what I mean???
12:11 PM Loetmichel: Jymmm: hihi
12:12 PM * Loetmichel uses his to "colour" engravings: http://www.cyrom.org/palbum/main.php?g2_view=core.DownloadItem&g2_itemId=11606
12:12 PM Loetmichel: maan, wrong video, sorry
12:12 PM pink_vampire: is that aluminum?
12:15 PM Loetmichel: http://www.cyrom.org/hajo/PowerKnoepfe.avi <- THATS the right video
12:15 PM Loetmichel: yes
12:15 PM Loetmichel: its aluminium
12:15 PM Loetmichel: its power buttons for PCs
12:16 PM fragalot: I have no idea what I just watched.
12:16 PM Jymmm: Loetmichel: black oil based enamel paint for "rub and buff" engraving filling works EXCELLENT
12:17 PM pink_vampire: what paint the pro.. use for that?
12:18 PM Jymmm: pink_vampire: are you aksing which paint?
12:20 PM Loetmichel: Jymmm: i know. crayons and a butane torch are just easier ;)
12:21 PM pink_vampire: yeah
12:21 PM Jymmm: Loetmichel: bullshit
12:21 PM Loetmichel: fragalot: a video of me engraving and then "painting" some power buttons
12:22 PM Loetmichel: Jymmm: if you say so.
12:22 PM Jymmm: Loetmichel: Just use an old rag, dip into paint (maybe a drop or two), then "rub" into the engraving, and wipe off the surface excess, takes 30 seconds
12:23 PM Loetmichel: i wannna see you do that with 0,2mm "deep" engravings
12:23 PM Jymmm: Loetmichel: I've done this for metal, stone, and plastics.
12:23 PM Loetmichel: the paint simply gets wiped out again by the rag
12:24 PM Jymmm: capilary action
12:24 PM Loetmichel: there is a reason i used a SINGLE LAYER of paper to clean off the excess crayon wax
12:24 PM Loetmichel: and not a cotton towel
12:24 PM Rab: Loetmichel, I've had the same issue; I usually use fine-grit sandpaper to brush the surface after the paint has dried.
12:25 PM Loetmichel: Rab: wasnt possible there: the surface of that aluminium knob is already painted silver
12:25 PM Loetmichel: so i couldnt even use a rag with acetone to clean it
12:25 PM pink_vampire: https://i.imgur.com/b2gHvhm.jpg https://i.imgur.com/JAotJPH.png
12:26 PM pink_vampire: those are stuff that i filled with paint
12:26 PM Rab: I use a paint pen, because usually with etching there are some pits and other imperfections and I don't want those filled: http://reboots.g-cipher.net/mark/p1000661.jpg
12:27 PM Jymmm: pink_vampire: I see the eyes, but wheres the lips?
12:27 PM Jymmm: pink_vampire: Is that a gun cabinet?
12:27 PM pink_vampire: correct
12:27 PM fdarling: pink_vampire: that's your CNC's electrical cabinet?
12:27 PM pink_vampire: yes
12:27 PM fdarling: nicely done
12:27 PM Rab: pink_vampire, you made the Berta logos?
12:27 PM pink_vampire: yes
12:28 PM Jymmm: pink_vampire: Nice, but that lol padlock will NEVER be used =)
12:28 PM Rab: pink_vampire, looks great.
12:28 PM pink_vampire: I love it!! i got the padlock for the machine
12:28 PM fdarling: pink_vampire: do you acid etch circuit boards?
12:29 PM pink_vampire: no, i ask the cnc and she engraved them
12:29 PM Jymmm: pink_vampire: Nice job on the controller
12:30 PM fdarling: pink_vampire: what DB25 breakout board is that in there?
12:30 PM pink_vampire: those are C10
12:30 PM pink_vampire: https://i.imgur.com/DpxLVfd.jpg
12:30 PM Jymmm: pink_vampire: Yeah, I know the padlock is just to satisfy your OCD =)
12:31 PM Rab: pink_vampire, which EDA software did you use for that board?
12:31 PM pink_vampire: LOL i did it in solidworks
12:32 PM pink_vampire: i don't have ocd https://i.imgur.com/yRT7hCB.png
12:34 PM Loetmichel: pink_vampire: you must be german then
12:34 PM Loetmichel: thats WAY to neat for a french or american or italian teminal block ;)
12:35 PM pink_vampire: hehe why?
12:35 PM Loetmichel: close to perfection wi would wager to say
12:37 PM pink_vampire: yes it is all ABB made europe/ germany
12:37 PM Loetmichel: i meant the wiring
12:38 PM Loetmichel: not the terminal blocks/fuses/contactors
12:38 PM pink_vampire: the wiring is usa made
12:38 PM * Loetmichel once rewired an appartement for my cousin.
12:38 PM Loetmichel: then the Utilities had to place a new meter.
12:39 PM pink_vampire: why?
12:39 PM Loetmichel: the utility guy looked into the fuse board: "thats wasnt done by a pro? thats WAY TO NEAT for someone that was lived "time is money!""
12:40 PM Loetmichel: because the old was single phase and the new wiring was three phase
12:40 PM pink_vampire: three phase... dream...
12:40 PM Loetmichel: its standard in germany
12:40 PM Loetmichel: more or less
12:40 PM Loetmichel: unless you get a building from the 60ties
12:40 PM pink_vampire: here there is only split phase
12:41 PM Loetmichel: and even those old builings usually have 3 phase service coming in, but get split per flat/appartment into single phase
12:42 PM Loetmichel: we dont use split phase in europe
12:42 PM Loetmichel: its 3phase or single phase over here
12:42 PM pink_vampire: also 110
12:42 PM Loetmichel: and 230/400V ;)
12:43 PM pink_vampire: 400V dream...
12:43 PM pink_vampire: but here the 220 outlet is 220V 50A
12:44 PM pink_vampire: 6awg wire
12:45 PM Loetmichel: normal homes here have 3*32A main fuses
12:46 PM Loetmichel: and usual "block" transformers" for half a dozen homes have about half an MW maximum
12:46 PM pink_vampire: i tink her it is 2*200A or something like that
12:46 PM gregcnc: all depends
12:48 PM Loetmichel: so you can usually get up to 3*250A without much hassle (albeit a bit of digging to the street if the last few meters of wiring are to small), much more than that is usually pretty expensive because they have to dig up the street and put in bigger wires and change the transformer to a bigger one
12:48 PM Loetmichel: the "neighborhood transfomer"
12:49 PM pink_vampire: one day i will get better machine...
12:49 PM Loetmichel: we have nearly NO overhead power supply any more so the "pole transformers" for a single house that one sees in american movies arent a thing here
12:50 PM pink_vampire: i need some sleep, and food
12:50 PM Loetmichel: over here the is usually a three phase 10+15kV ring line underneath the streets, every other intersection there is a little green "doghouse on someones lawn that houses the transformer for the next few houses
02:05 PM fragalot: Loetmichel: I just visited my sisters' house she bought last week to check out the electrical installation... it's an abomination.
02:05 PM fragalot: the 2 switch lights (no idea what you call that in english) don't flip between 2 wires, but it flips the phase on the light to switch it off or on >.<
02:06 PM fragalot: so when the light is "off", both wires are on phase A, or on phase B, depending on the state of the switches
02:06 PM fragalot: if you toggle either switch, you get A B or B A to switch the light on
02:07 PM fragalot: I knew it was going to be outdated & everything needed to be replaced from the ground up, but i'd never seen it this bad :P
02:08 PM fragalot: also - she's still in a street that has concrete power poles. probably the last one around, lol
02:09 PM _abc_: Hi. I'm trying to create a toolpath for linuxcnc using pycam from a simple stl object. The "waterline" algorithm gives me grief. Does anyone know if it should trace only the contours of the slice or zig zag in it as it does in my case?
02:14 PM Loetmichel: fragalot: which country?
02:14 PM fragalot: Loetmichel: .be
02:14 PM Loetmichel: ah.
02:14 PM Loetmichel: no idea there
02:14 PM fragalot: it's normally the same here as you described
02:15 PM fragalot: but overhead poles are still around, but are being phased out
02:15 PM fragalot: the transformers are never on the pole though, the poles just run wiring
02:15 PM Loetmichel: in germany what you described is called a "berliner wechselschaltung" and is strictly forbidden
02:15 PM fragalot: it is forbidden here too
02:15 PM fragalot: hence the "abomination"
02:16 PM fragalot: wires changing color within their piping too
02:16 PM fragalot: random wire sections, tc
02:16 PM fragalot: etc
02:16 PM Loetmichel: if you would do that in a german apprentice test you would fail the whole test and have to redo the last year of apprenticeship
02:16 PM Loetmichel: THAT kind of forbidden
02:17 PM fragalot: it's unacceptable, end of story
02:19 PM _abc_: Do it in enemy countries.
02:19 PM * Loetmichel is mulling over his youtube subscriptions... SvSeeker, Mustie1, Bad obsession Motorsport, elderly iron, clickspring, finding simon, matthias wandel, pure living for life, red poppy ranch, sampson boat co, the crazy framer... i think i am WAY to much a "DIY" guy than is good for me ;)
02:20 PM Loetmichel: ah, forgot april wilkerson ;)
02:20 PM fragalot: i'm not sure I have any subscriptions that AREN'T a 'DIY' channel
02:21 PM fragalot: except for bosnianbill & lockpickinglawyer
02:21 PM Loetmichel: i have a few, but they are from gamer channels
02:22 PM fragalot: i've got a few of those too
02:22 PM fragalot: typically runs in the background for the banter
02:23 PM Loetmichel: of course i have TOT and AVE, too ;)
02:23 PM fragalot: I found another fun one yesterday
02:23 PM Loetmichel: ... for the banter ;)
02:23 PM fragalot: let me see if I can find it again in my history
02:23 PM fragalot: https://www.youtube.com/watch?v=NWzPCLcbExo
02:27 PM Loetmichel: fragalot: way to much a mirror for me...
02:28 PM Loetmichel: that could be me, just that my voice is less raspy and i have a german accent ;)
02:28 PM fragalot: :D
02:28 PM fragalot: there are a few gems on that channel
02:31 PM Loetmichel: fragalot: i must say that i admire Doug from SVSeeker for what he does. he has the right attitude... "impossible because i dont konw how? I dont think so!" and just LEARNS how to.
02:32 PM fragalot: AND gets free labor from inexperienced people, and they get a free hands-on course on how to get shit done
02:32 PM roycroft: i have no youtube subscriptions
02:32 PM Loetmichel: or "maaan ship propellers are EXPENSIVE... but brass is cheap... and proceeds to learn how to cast brass and makes his own propeller :-)
02:32 PM roycroft: it is impossible to watch youtube in real time
02:32 PM Loetmichel: fragalot: indeed
02:32 PM roycroft: whenever i want to watch something i just download it and then delete it when i'm done watching
02:33 PM fragalot: I used to have that problem
02:33 PM fragalot: but then I made it to 2012
02:33 PM roycroft: and i have enough distractions already without being notified that there's some new video for me to watch
02:33 PM fragalot: I don't use notifications, but I do use subscriptions & check them periodically
02:33 PM Loetmichel: same here
02:35 PM Loetmichel: fragalot: i also like his take on personal safety equipment: "wear what you think you have to, its all here, but dont come whining when you didnt wear something and got hurt.
02:35 PM Loetmichel: "
02:38 PM roycroft: it looks like 2% lanthenated electrodes are what most folks recommend for mild steal, and i think i have some, so that would be brilliant
02:39 PM fragalot: those work well, i've still got too much thoriated to use up first though that works fine
02:39 PM fragalot: just.. don't breathe the dust :P
02:39 PM roycroft: i have some thoriated electrodes
02:39 PM roycroft: but yes, breating in radioactive dust is not recommended
02:39 PM roycroft: breathing
02:43 PM _abc_: Not all Th is radioactive. You do not have Th232 electrodes
02:43 PM _abc_: Is there some way to save a project's settings in pycam? There are 30 manual settings and no way to save them?!
02:44 PM fragalot: _abc_: it still emits alpha particles, which your skin blocks fine, but your lungs & organs don't
02:44 PM _abc_: no
02:44 PM _abc_: BUT "usual" Th does contain traces of Th232 which does what you said
02:44 PM fragalot: also - never used pycam (just to get that out of the way :-) )
02:44 PM _abc_: But there is very little.
02:45 PM fragalot: In a review of air sampling measurements carried out during grinding it was concluded that during grinding air concentrations could approach or even exceed concentrations at which it would be necessary to consider designating the area as a controlled area as defined by the Ionising Radiation Regulations 1999.
02:45 PM fragalot: according to twi
02:47 PM _abc_: grinding of what. You realize that normal Th is post refining, because Th232 is valuable and removed for other uses? Also it would be illegal to sell to the public if it would not be removed.
02:47 PM _abc_: fragalot: check out Th232 isotope price per gram and you'll get it
02:48 PM fragalot: _abc_: get a geiger counter, put it on a stack of 2% thoriated tungsten electrodezs
02:48 PM fragalot: it DOES emit a small amount of radiation
02:48 PM Tom_L: _abc_ you get your install sorted out?
02:49 PM fragalot: perfectly harmless level for normal use, especially given that you don't walk around with them in your chest pocket, but the dust is still a radioactive substance that you inhale. In no case is that something good.
02:49 PM _abc_: Tom_L: yes and no. It works but it does not work with persistence from usb stick. More work to do there, the config in the live release conflicts with the live scripts in certain ways.
02:49 PM _abc_: fragalot: put the Geiger on your grandma's gravestone or on a granite kitchen top and tell me what you see.
02:50 PM Tom_L: wouldn't that be radon?
02:50 PM _abc_: No, the radon comes after the radiation. And then turns into Po which is the real bad thing.
02:50 PM _abc_: There's Uxxx in granite, lots of it usually.
02:51 PM _abc_: Ra is a daughter product from spontaneous Uxxx fission and is a gas which you can inhale. Then Ra spontaneously decays into Po which is solid and stays in the lungs. And that will slowly kill you
02:52 PM _abc_: I think it's Rd radon not Ra.
02:53 PM Rab: _abc_, I am not sure these attributes of granite illustrate anything with regard to thoriated tungsten.
03:06 PM _abc_: They do not.
03:06 PM _abc_: I see there are non Th containing alternatives http://www.pro-fusiononline.com/tungsten/radioactivity.htm
03:06 PM fragalot: yeah there are

03:08 PM skunkworks: could have used a little bigger circuit board...
03:09 PM _abc_: Hall sensors for rotation indexing?
03:10 PM skunkworks: gear tooth sensors
03:10 PM skunkworks: quadature + index
03:11 PM fragalot: lneat
03:11 PM fragalot: -l

03:25 PM _abc_: my pycam version on linux does not have the "Save Task Settings *" menu entries. http://pycam.sourceforge.net/menu-items/#file-menu -- where would I find a version which has these? I got the latest pycam from the website.
03:26 PM _abc_: skunkworks: small magnet on back of each Hall?
03:27 PM _abc_: Apparently need 0.7.0 but that's not on the website?!
03:29 PM _abc_: yep release notes confirm 0.6.2 and up get worse (negative bounding boxes removed?!)
03:29 PM _abc_: Also the feture I need appears in 0.7.0+, saving workspace settings.
04:13 PM Deejay: gn8
04:28 PM devlap: Man I got money in my pocket burning for a lathe.
04:29 PM devlap: Can't decide what I want to get.
04:31 PM gloops: any shortlist devlap?
04:31 PM devlap: idk. thinking about going taiwan 14x40"
04:31 PM devlap: Who knows what your going to get used off ebay.
04:31 PM devlap: I see a lot of SB and what not, but idk, I don't want a project.
04:33 PM devlap: The used stuff on craigs list is pretty much the price of new taiwan stuff, so that wasnt helpful.
04:33 PM devlap: It looks like most people want a good chunk of change for their used *rap.
04:55 PM devlap: Monarch 10EE with broken tailstock handwheel. 10500$
05:10 PM _abc_: That is a little steep, no? Maybe if it includes a complete jig and tool set?
05:38 PM andypugh: I found the ideal packaging to post a 4-jaw chuck that I sold on eBay in the supermarket: https://photos.app.goo.gl/eEsneWm3kUU3A9WP7
05:44 PM Tom_L: andypugh i found if you have gcmc_lib, ngcgui_lib or remap_lib in nc_files directory you can't save sim files in 2.8
05:45 PM Tom_L: any of those directories
05:45 PM Jymmm: andypugh: you have room in there for some kisses too
05:46 PM andypugh: kisses?
05:47 PM Jymmm: andypugh: https://media.candystore.com/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/h/e/hersheys-kisses-25lb_2.jpg
05:47 PM andypugh: Never seen them in the UK
05:48 PM andypugh: And they might get stolen my the postman.
05:48 PM Jymmm: Oh wow, that kinda sucks
05:51 PM andypugh: What? That we can’t buy a particular sweet in the UK?
05:51 PM andypugh: (I was joking about the postman, just commenting that the packaging is entirely transparent)
05:51 PM Tom_L: you guys are missin out on alot of stuff
05:52 PM andypugh: And whyhas Stack Overflow gone all Geocities?
05:52 PM andypugh: https://stackoverflow.com/questions/11552320/correct-way-to-pause-python-program
05:54 PM andypugh: And there are confections and foods that you miss out on too, even YouTube vidoes about them, like: https://www.youtube.com/watch?v=1k9AzsOblic
05:56 PM Tom_L: andypugh, she watches them all the time: https://www.youtube.com/watch?v=gE0DmvoN9l0
05:56 PM devlap: andypugh, they did it for april 1st
05:57 PM andypugh: devlap: It takes me right back.
05:57 PM Tom_L: https://www.youtube.com/watch?v=Nxi5ZecCpjU
05:57 PM devlap: you just need <blink> now
10:28 PM Tom_L: so in qtpyvcp, how do you know what the syntax is for the sets of rules?
10:29 PM Tom_L: kindof a late night question when all is dead...
11:27 PM Lcvette: Tom_L: Tom_L it's in the docs
11:27 PM skunkworks: 25khz work single ended over about 4ft?
11:27 PM Lcvette: Jt wrote it all out for each type with an explanation
11:27 PM skunkworks: boy - I would think so...
11:36 PM Tom_L: o
11:36 PM Tom_L: i'll look for it tomorrow
11:37 PM Tom_L: just looking at one of his examples trying to see how a button ties to a hal pin
11:38 PM Tom_L: skunkworks i would think so too
11:39 PM Tom_L: is it hard to set dual monitors on debian?
11:39 PM Tom_L: i may set linux up on my main pc 3rd hdd
