12:22 AM jesseg: well we got 8 little Kodiak endmills for $52 delivered. They look really nice; haven't tried them out yet.
12:33 AM nallar is now known as Ross
01:57 AM Deejay: moin
05:50 AM jthornton: morning
05:50 AM XXCoder: hey jt
05:56 AM sensille: Loetmichel: i now made a sub-d 25 cable. do i need to rework anything inside the control box or just connect it?
06:24 AM weenerdog: howdy
06:25 AM XXCoder: hey
06:25 AM weenerdog: sup
06:26 AM XXCoder: not a lot
06:39 AM jthornton: I think I found the problem with my systemd coop.service file :)
06:40 AM XXCoder: oh wyhat was issue?
06:41 AM jthornton: my ExecStart line did not specify python3 so the library was not found lol
06:41 AM XXCoder: doh so it didnt run at all, or missing library so call for time didnt work or something?
06:43 AM jthornton: ImportError: No module named 'pytz'
06:44 AM XXCoder: pytz? weird?
06:45 AM jthornton: yea I only have the python3 version installed so apparently when systemd runs the file it ignores the shebang line
06:46 AM jthornton: another problem solved lol
06:47 AM XXCoder: such a strange error for not found python3
06:47 AM XXCoder: or more properly, not specified
06:51 AM jthornton: yea odd that it ignored the shebang line that has python3
06:52 AM jthornton: also odd is my 2TB WD Red drive that stopped yesterday and now is running fine
06:52 AM XXCoder: what errors were it having? checked SMART?
06:53 AM jthornton: no errors just no display, can't find smart on here yet
06:54 AM XXCoder: linux does have program to read that but no idea on others
06:54 AM jthornton: yea I think it is included with bloated gnome looking for it now
06:55 AM XXCoder: wow I love the effect filing but shopwing cuts but not files https://www.youtube.com/watch?v=zgDVx9tg0lQ
06:56 AM XXCoder: hes making play logo youtube without using any power tools just fles
06:59 AM XXCoder: lol now grooving chisel "no tool magically cutting" effect also
07:00 AM weenerdog: pretty work
07:03 AM weenerdog: be funnier if he made a linuxcnc or fanuc logo like that
07:03 AM XXCoder: I made new version of linuxcnc logo
07:03 AM XXCoder: so far nobodys interesting on swapping logos so we can use larger logos
07:03 AM XXCoder: (vector since orginial is not_
07:04 AM weenerdog: penguin beating the keys with his flippers?
07:04 AM jthornton: yea vector is better
07:04 AM XXCoder: I still think eyes isnt perfect on my version but otherwise its done]
07:06 AM jthornton: smart tests are all ok so maybe it was the sata cord dunno
07:08 AM Tom_L: happy friday...
07:09 AM jthornton: yea!
07:09 AM jthornton: you getting any rain over there?
07:09 AM XXCoder: yay
07:09 AM XXCoder: know whats better than friday?
07:09 AM XXCoder: friday when been working and under the weather
07:09 AM jdh: a week of.
07:09 AM XXCoder: yay finally dont have to work
07:13 AM weenerdog: thats cool
07:13 AM weenerdog: its gonna be up to 50 here today. i got a bunch of stuff to do around here.
07:16 AM jthornton: it already is 50°F here and if the rain holds out I'll burn a bunch of branches
07:17 AM XXCoder: mid-40s f all week, and 30s f most nights here
07:17 AM XXCoder: temperates very stable here usually
07:17 AM XXCoder: yours is quite wild varancy compared to here
07:23 AM weenerdog: if my dad wasn't old and frail and needs a lot of help, i'd have moved to clarkston, wa 3 years ago
07:31 AM XXCoder: my dad died years ago, but same time he was 71 years old and had lerkemia for 10 years
07:40 AM XXCoder: oops I meant 76
07:40 AM XXCoder: he'd be 92 now
07:55 AM weenerdog: hey just what i need "Learn Solidworks in 5 Minutes! | Solidworks Tutorial" https://www.youtube.com/watch?v=hVG5tMAhf3Q
07:56 AM XXCoder: nice
07:57 AM XXCoder: i dont use solidworks but nice
07:58 AM jthornton: getting old sucks, took me 10 minutes to remember where I put Dad after the last furniture shuffle
07:59 AM jthornton: must be 5 minutes of crap if you can learn in 5 with a 10 minute video
08:01 AM XXCoder: 5 minutes of intro and outro
08:02 AM jthornton: now I need to figure out what the linux path to the nas is so I can get borg to backup
09:43 AM sensille: on a 6040, would you call the 60cm the x-axis and the 40cm the y-axis? where is the 0/0 normally?
09:48 AM jthornton: machine home is Z all the way up, Y all the way out and X is usually all the way left
09:49 AM sync: on a vertical milling machine 0/0 is usually in the left rear corner
09:50 AM sync: and Z0 is at the table
09:50 AM sync: although the numbers don't matter much, but the directions do
09:53 AM rmu: you want a right-handed coordinate system ;)
09:56 AM sensille: ok, thanks
10:00 AM Loetmichel: sensille: just connect it
10:00 AM Loetmichel: should work fine
10:01 AM Loetmichel: ... if you have the pinout right in stepconf ,)
10:01 AM Loetmichel: :-)
10:01 AM Loetmichel: sensille: the coordinate system depends on where you look from
10:01 AM Loetmichel: my 6040 sits sideways, so my gantry moves in x
10:03 AM Loetmichel: but if you sit "in front" of it (looking on the nut of the gantry ballscrew) then the gantry moves in y and the spindle moves ON the gantry in x and z
10:08 AM JT-Shop: z0 at the table is bad bad bad when you home if you have a tool in you crash!!!!
10:13 AM skunkworks: JT-Shop: you can set home so it is at say 24" (so 0 is the table)
10:13 AM JT-Shop: yea you can do that safely
10:14 AM skunkworks: The K&T is kinda like that... (just because that is how it was originally)
10:14 AM sensille: Loetmichel: i think i nearly have it. a few values are still unclear: pulse widths for the steppers, dir setup/hold, enable1/enable2, max feedrate, max accel
10:14 AM JT-Shop: I assume it still homes Z up to max?
10:15 AM sensille: but i just got my first successful testrun :)
10:15 AM sensille: Loetmichel: do you have pictures where you mounted your endstops?
10:16 AM sensille: Loetmichel: and the spindle can only be controlled manually, right?
10:16 AM skunkworks: JT-Shop: yes
10:17 AM skunkworks: Y homes all the way up which is 36"
10:17 AM sensille: and i set z0 to the topmost position, 0 to -75mm
10:17 AM skunkworks: it could be 0 but then all machine moves would be negative.. (not that is a big deal(
10:19 AM Loetmichel: sensille: http://www.cyrom.org/palbum/main.php?g2_itemId=17088&g2_imageViewsIndex=1
10:19 AM gloops: https://www.ebay.co.uk/itm/CNC-BALLSCREW-1000mm-x-30mm-10mm-Pitch-Dia-Bridgeport-colchester-Lathe-Milling/302978119324?
10:19 AM Loetmichel: the x axis (gantry movement is on the lft side behind the rail, no pic of that, sorry
10:19 AM gloops: cheap engineering quality screw there
10:20 AM Loetmichel: no, you sould set z0 to er11 hitting table
10:20 AM Loetmichel: and your endstop on z-80 or so, depending on how fat z can move
10:20 AM Loetmichel: oh sorry, your ref switch
10:21 AM sensille: would a microswitch without lever do?
10:21 AM gregcnc: methods_ clausing doesn't have the spindle so they sent a print
10:23 AM gregcnc: a couple guys might have parts on the clausing yahoo group.
10:23 AM Loetmichel: it would do, but you will ram into the end of the travel every ref time then because they have not enough "pressing lenght" after the click for the axis to do a decelleration rammp
10:24 AM sensille: Loetmichel: what, z moving upwards as positive?
10:24 AM Loetmichel: yes
10:24 AM Loetmichel: into the workpiece is negative
10:24 AM sensille: hm
10:29 AM sensille: and you just drilled/tapped holes to mount the endstops?
10:32 AM Loetmichel: yes
10:32 AM Loetmichel: 2,1mm drill, M2.5 tapped
10:42 AM methods_: gregcnc: ah that's great of them
10:42 AM methods_: wish everyone would do that
10:45 AM CaptHindsight: gregcnc: what happened to the spindle?
10:46 AM gregcnc: dropped something between the jaws and ways. Didn't realize how bad the damage was until my chuck was .005" TIR the other day
10:48 AM gregcnc: The print calls says this shaft is 44-52HRC. doesn't seem that hard. anyhow i'm hoping someone in the clausing group has one.
10:51 AM gregcnc: I did find a nice Harrison on Ebay close by, but everyone wants 5kUSD for a lathe today
10:57 AM CaptHindsight: https://milwaukee.craigslist.org/hvo/d/small-engine-lathe/6750841229.html
11:08 AM weenerdog: https://greenville.craigslist.org/tls/d/leadwell-cnc-lathe/6734207927.html
11:13 AM Loetmichel: maaan... that'll be fun on monday and tuesday... just finished another one of these: http://www.cyrom.org/palbum/main.php?g2_itemId=16432&g2_imageViewsIndex=1 ... each plate can hold 4 units... i need 24 units 'til tuesday evening... and have only material left for 8... anyone knows a source of 500mm by 1000mm b y 8mm hard PVC black sheets around seligenstadt, germany that i can fetch monday
11:13 AM Loetmichel: morning? (and some new dirtbags for the vacuum ;)
11:18 AM roycroft: looks like a lot of schmutz to me
11:21 AM fragalot: There is only zuul.
11:24 AM roycroft: there is also vinz clortho
11:24 AM CaptHindsight: I thought schmutz was more oily
11:26 AM roycroft: schmutz literally means "dirt"
11:26 AM gregcnc: i thought that was smegma
11:27 AM Loetmichel: roycroft: and tha bad thing is that that swarf is electrostatic (being PVC) and clings to ANY surface including you ;)
11:28 AM Loetmichel: roycroft: "schmutzig" is dirty "schmutz" is more like grime
11:28 AM Loetmichel: not dirt in the "plant your flowers in" sense
11:29 AM Loetmichel: THAT dirt would be called "Dreck" in german
11:30 AM Loetmichel: (soil is the word i couldnt remember)
11:34 AM roycroft: yeah, grime would be a better translation
11:34 AM roycroft: i used the correct word, i just translated it wrong :)
11:35 AM Loetmichel: indeed
12:13 PM Tom_L: 44°F & cloudy but no rain yet
12:37 PM weenerdog: 49 drizzle here
12:42 PM sensille: Loetmichel: now for the spoilboard... really double sided tape? will i ever be able to clean it again?
12:44 PM Loetmichel: depends on the tape ;)
12:45 PM gloops: acetone or cellulose thinners if on metal
12:46 PM fragalot: i've got this purpose made glue remover I use a lot from HG
12:46 PM Loetmichel: sensille: i have spray cans with "solvent 50" at the company... that stuff can get rid of ANY "tape glue" stuff
12:46 PM fragalot: dab on, let it soak for a few seconds, and most if not all common sticker or tape glues just wipe off
12:46 PM Loetmichel: and dont attack most plastics
12:46 PM fragalot: ^
12:46 PM gloops: warm it up
12:47 PM gloops: the high built crap you can scrape off
12:48 PM Loetmichel: or use pure orange oil from the "reformhaus"....
12:48 PM Loetmichel: it will solve ANY glue related problem
12:48 PM Loetmichel: and smell nice
12:48 PM fragalot: 'the hell is a reformhaus
12:49 PM sensille: :)
12:49 PM Loetmichel: fragalot: a place where to get "organic" foods and household items
12:49 PM fragalot: I see
12:49 PM Loetmichel: in germany
03:32 PM Deejay: gn8
03:35 PM gloops: hmm, i need to make some of these https://www.ebay.co.uk/p/Veritas-Metal-Bender-50K0801-by-Tyzacktools/682106093?i
03:57 PM JT-Shop: can you make them for < 20 pounds?
03:58 PM gloops: yeah, bit of angle iron lol
04:00 PM JT-Shop: lol, not as pretty I imagine but functional
04:43 PM Loetmichel: gloops: the small ones for the vice are BS
04:44 PM Loetmichel: they dont wor that well
04:44 PM Loetmichel: or have clearance for even moderately large bends
04:44 PM SpeedEvil: They work fine for small enough pieces
04:44 PM weenerdog: howdy
04:45 PM Loetmichel: i would prefer to build one on the base of a bottle jack shop press
04:45 PM SpeedEvil: But yeah, bending reasonable sized stuff takes unreasonable forces.
04:45 PM Loetmichel: where you have front and back room as you see fit
04:45 PM * SpeedEvil wants a 100 ton hydraulic press.
04:45 PM Loetmichel: dont need to be 100 ton
04:45 PM SpeedEvil: I don't have the accent anyway.
04:45 PM Loetmichel: a simple I-beam frame and a 20 ton truck bottle jack can do wonders to bend stuff
04:49 PM * JT-Shop feels small he only has a 50 ton press brake
05:13 PM Loetmichel: JT-Shop: 50 ton bottle jacks are hard to come by
05:13 PM Loetmichel: 20 ton are pretty common
05:13 PM jthornton: mine is not a bottle jack :)
05:13 PM Loetmichel: also if you selfbuild the frame its a lot less "prone to accident" to do it for 20 ton
05:14 PM Loetmichel: 50 ton on a steel i beam frame and you need serious engineering math... 20 ton you can get buy with "gut feeling +100%"
05:14 PM Loetmichel: by
05:15 PM jthornton: http://gnipsel.com/images/press-brake/press-brake-09.jpg
05:15 PM Loetmichel: buying is easy if you have the money. selfbuilding makes proud ;)
05:15 PM jthornton: I built the press brake but had the 50 H frame press already
05:15 PM Loetmichel: yeah, that would work as well
05:16 PM jthornton: it has a back gauge as well
05:16 PM Loetmichel: the bending V and -knife is pretty easy to do
05:17 PM jthornton: more photos here http://gnipsel.com/images/press-brake/
05:17 PM Loetmichel: one of the contract manufacturers for our company has a big trump CNC punch and a big trump CNC brake
05:19 PM Loetmichel: cant remember the tonnage but it can bend half inch steel on 8 feet width
05:19 PM Loetmichel: oh sorry
05:19 PM Loetmichel: quarter inch, not half inch
05:19 PM Loetmichel: (get a bit confused with that imperial stuff sometimes)
05:20 PM Loetmichel: (6mm thick steel and 2.5 meters width)
05:20 PM Loetmichel: and the punch can cut full size quarter inch steel sheets as well
05:21 PM Loetmichel: ... you can feel it punching 6mm steel across the street on the sidewalk though...
05:21 PM jthornton: that's a big one for sure
05:23 PM * Loetmichel was watching him bend small parts for another customer lately (enclosure about the size of a box of cigarettes made of 1,5mm galvanized steel)... THATS a job i dont want to have...
05:23 PM * jthornton tries to figure out how to use borg to backup to the nas...
05:24 PM Loetmichel: that big knife coming down while your fingers are literally half an inch away from the blade
05:24 PM Loetmichel: .... and thats coming from one that does things like this: https://www.youtube.com/watch?v=1Ym4Y9HEm4s
05:25 PM jthornton: looks safe enough to me :)
05:28 PM Loetmichel: i mean: all that the mill bit can do is damage some fingers or bones... been there done that, have the xray to prove it... but getting your fingers into a hydraulic driven monster like that? no thanks... there is nothing left to sew back on if something goes wrong there
05:29 PM Loetmichel: at least i only lost some bone material and had to wait till the thumb nail had regrown ;)
06:03 PM Ross is now known as nallar
06:20 PM XXCoder: Loetmichel: that bender well it does depend on user case
06:21 PM XXCoder: ohhh https://www.youtube.com/watch?v=bpJyqLoqV04
07:09 PM weenerdog: howdy again
07:10 PM XXCoder: wb
07:16 PM infornography: ello
07:16 PM XXCoder: llo
08:22 PM XXCoder: so now I have 2 copies of a vismach config lol
08:22 PM XXCoder: the orginal and one that comes with linuxcnc update. feels bit weird.
08:22 PM XXCoder: kinda "wow I did this."
08:39 PM weenerdog: i felt the same way when my gf faked an orgasm once :)
08:39 PM XXCoder: lol
08:40 PM MarcelineVQ: "She pretended to have an orgasm, I​ pretended to pay the rent."
08:40 PM weenerdog: lololol
08:47 PM XXCoder: lol
09:10 PM weenerdog: ./topic CNCOrgasms
09:11 PM weenerdog: that would be a cool channel name. lol for off-topic bullshit
09:15 PM XXCoder: guess so
09:27 PM weenerdog: back in the 90s me and some friends had a channel on undernet called #llamasex
09:27 PM weenerdog: it was the side channel for a c programming chan. but eventually it got known for providing real good help
10:16 PM flyback: https://www.youtube.com/watch?v=hfsAeLg10H4
10:22 PM weenerdog: steel dust. the OTHER other white meat
10:35 PM XXCoder: 10 year old video dang
10:35 PM XXCoder: no wonder I had to wipe dust off my montior few times so far
10:39 PM XXCoder: flyback: wow interesting video so far.
10:42 PM weenerdog: i watched the whole thing
10:44 PM weenerdog: saving the children from steel dust
10:45 PM weenerdog: word! muhfukka!
10:45 PM weenerdog: when i was a kid, we rassled in steel dust
10:46 PM weenerdog: the rust belt was a rasslin trophy
10:47 PM XXCoder: well "im ok therefore its ok for everyone" never weas a valid argument
10:47 PM weenerdog: true enough
10:50 PM weenerdog: what kinda workstations were those hooked up to the whatchyacallit kiln? old hps?
10:52 PM weenerdog: i did visiting support for a leather cutting system that ran on hp9000 "work"stations back in the mid 90s
10:53 PM weenerdog: hpux rhymes with _______ :)
10:54 PM weenerdog: howdy Mongrel_Shark
10:55 PM weenerdog: can you tell me how to get Command & Conquer for linux to run? everyone else has /ignored me
10:58 PM Tom_L: why did they do that?
10:58 PM weenerdog: lol
11:00 PM weenerdog: man i'll be glad when my tracybear gets home
11:04 PM weenerdog: howdy Karl
11:15 PM Test is now known as Guest26179
11:20 PM flyback: XXCoder, there's ones that do expensive alloy shit
11:20 PM flyback: they collect millings etc
11:20 PM flyback: dust
