12:58 AM jelly-home is now known as jelly
01:19 AM miss0r: Belgium phone service is nice. I don't think I've ever had a bad experience with anyone from there
01:19 AM miss0r: like phone based tech support
01:33 AM miss0r: why people use TiN coated endmills for alu is beyond me!
01:50 AM Deejay: moin
03:12 AM Loetmichel: *haach ja*... battery management tools in notebooks... just got my "car" notebook back out of the wintercar, charged it after not using it for half a year: runnung time 20 min of formerly about 3 hours... Battery management says "battery condition: good!"... i wonder what the performance is if that tool says "bad"...
04:46 AM XXCoder: miss0r watching orange minion restore on that channel
04:46 AM XXCoder: sadly that one dont have captions nor text
04:51 AM XXCoder: oh finally some text on video
04:51 AM XXCoder: https://www.youtube.com/watch?v=Se47FWgfub0 if curious
04:56 AM jthornton: morning
04:57 AM XXCoder: hey jt :)
04:58 AM XXCoder: jt man im getting addicted to that channel.
04:58 AM XXCoder: TAA = Tysytube anonomous ;)
05:04 AM jthornton: is that the same one that blackened the metal in rapeseed oil?
05:04 AM XXCoder: nah different one, that was vise
05:05 AM XXCoder: that one looks like pretty old style hard case light
05:05 AM jthornton: I mean same channel?
05:05 AM XXCoder: oh! yeah
05:05 AM XXCoder: he makes pretty amazing videos. he started just couple months ago!
05:05 AM XXCoder: so its new channel
05:05 AM XXCoder: already at 49k subs tho, not a surpise
05:20 AM Tom_itx: morning
05:20 AM XXCoder: hey tom
05:24 AM jthornton: looks like snow here today and tonight but gone by thursday
05:25 AM jthornton: opps gone by friday with a high of 53f
05:25 AM Tom_itx: 20°F Hi 39
05:25 AM Tom_itx: not quite as chilly as yesterday
05:26 AM jthornton: we are about the same here today 27.3°F in the roost box
05:26 AM Tom_itx: looks like the bulk of it is SE of you
05:28 AM Tom_itx: are they less active in the cold?
05:28 AM XXCoder: watching balance weights restore
05:28 AM XXCoder: 1920s one
05:29 AM jthornton: when it's cold and windy they huddle up but if it's not windy or rainy they move around normally
05:32 AM XXCoder: https://www.youtube.com/watch?v=j6yWAsWUwbo
06:17 AM jthornton: I wonder what this means "10-point touch capacity for virtual keyboards and multi-touch applications " https://www.amazon.com/gp/product/B01N4U7E7H
06:20 AM jthornton: https://www.asus.com/us/Monitors/VT168H/
06:21 AM XXCoder: 10 touch at same time
06:21 AM jthornton: cool you can type on it with more than one finger
06:21 AM XXCoder: yeah
06:21 AM XXCoder: touch screen screen fo 171 bucks? pretty cheap I think?
06:23 AM jthornton: yea every chicken coop needs a touch monitor lol
06:23 AM XXCoder: lol
06:23 AM XXCoder: im pretty sure small ones is real cheap
06:24 AM jthornton: I have a 7" raspberry pi touch monitor but the keyboard is just too small lol
06:24 AM XXCoder: theres interesting hacks to get eink device as variouis stuff but dunno
06:27 AM XXCoder: https://www.element14.com/community/thread/60695/l/using-a-kindle-epaper-screen-with-raspberry-pi?displayFullThread=true
06:28 AM jthornton: interesting
06:28 AM XXCoder: its not very easy to drive directly without fairly expensive driver sadly
06:28 AM XXCoder: there is few out there
06:30 AM XXCoder: http://essentialscrap.com/eink/ for example
06:31 AM XXCoder: http://essentialscrap.com/eink/software.html something you would like I guess
06:34 AM jthornton: well qt5 gives me errors on the RPi and qt4 does not so I'll use qt4 for now lol
06:34 AM XXCoder: lol
11:40 AM Lcvette: pcw_mesa some old school baby servo drives

01:26 PM pcw_mesa: Lcvette: interesting, I forget, are those analog or PWM?
01:29 PM Lcvette: pwm
01:29 PM Lcvette: spindle board too
01:29 PM Lcvette: circa 1993
01:31 PM pcw_mesa: no funny parts so probably reparable should something break

01:42 PM Loetmichel: btw: got the new "original" battery for the Samsung note3 today. for 6.82€ including shipping on ebay. And i must say: its either really an original one or a perfect copy. Couldnt find any difference to the one that was in the GT-N9005 other than that it lasts longer than 3 hours AND has a oc 2018 datecode instead of a nov 2013 one... which is not a bad lifetime for a liion flat pack to be
01:42 PM Loetmichel: honest... ;)
01:53 PM gregcnc: pulled out an old canon SD300 for the kids to play with original battery still works
01:54 PM Loetmichel: is that li* or Ni* battery chemistry?
01:54 PM gregcnc: li
01:55 PM Loetmichel: amazing
01:56 PM Loetmichel: my canon A20 still wors, too... but only for about 10 pictures per charge
01:56 PM Loetmichel: its a lot older thouhg
01:56 PM Loetmichel: s/a20/s20
01:56 PM gregcnc: kids are making lego stop motion
02:03 PM MarcelineVQ: hehe neat, that brings back memories
02:09 PM gregcnc: if I built stuff, it had to be very orderly. houses had courses of the same color and overlapped neatly to be strong
02:09 PM gregcnc: they just do whatever and call it "color hotel"
02:10 PM gregcnc: that is to say when i built stuff as a kid
03:03 PM Connor: Resuming work on my G0704 CNC after a long while being in parts.. the SSD I had was bad.. so, reloading LCNC for the first time in 2 or more years. Well.. since switching from Ubuntu to Debian
03:04 PM Connor: It was original setup with Parallel port, then was switching over to MESA. I completely forgot everything about how it was setup.. I'm even going to have to go back and retrace wiring and stuff.. :(
03:22 PM * JT-Shop thought what the heck you have leather gloves on you don't need to turn off the electric fence to tighten up a few standoffs... BAAAZZZAAPP right on the tip of my ring finger and it still hurts and I love my electric fence
03:54 PM Deejay: gn8
03:56 PM XXCoder: wow!!
03:56 PM XXCoder: https://www.popularmechanics.com/science/environment/a25051641/mythbuster-jamie-hyneman-wildfire-tank-sentry/
03:57 PM XXCoder: wonder what Jamie is doing since mythbuster? well this is it
04:04 PM andypugh: Seems like a reasnably good idea, but possibly starting with the wrong vehicle.
04:04 PM renesis: its unmanned?
04:04 PM andypugh: Extremely cheap would be a better starting point, these things need to be disposable.
04:04 PM XXCoder: renesis: automous or remote control yeah
04:05 PM renesis: k because aluminum basically means its suicidal
04:05 PM XXCoder: dunno disposable and unbreakable in fires dunno
04:05 PM andypugh: Autonomous would be gool, but too hard and too pointless.
04:05 PM andypugh: Remote piloted is just going to be a whole lot more adaptable.
04:05 PM XXCoder: andypugh: I suspect its not to fight fires all on its own but rather break really hot spots
04:06 PM XXCoder: then fire fighters can supress rest of fire around it and not get hurt or killed
04:06 PM andypugh: (Imagine seeing someone that it would be possible to rescue on the monitors, but the autonomous code not having that imagination)
04:06 PM MarcelineVQ: semi-autonomous is the path
04:06 PM MarcelineVQ: So you can run a routine and have one pilot running a couple at once, among other advantages
04:06 PM andypugh: I drive a fire engine, you know :-)
04:08 PM XXCoder: nice
04:09 PM andypugh: In fact, here I am driving the fire engine. https://goo.gl/images/3BkXvz
04:09 PM MarcelineVQ: another completely reasonable route is partition rifts, covered trenches essentially, that can collapse into fire breaks with a button press, I'm sure nothing could go wrong there :>
04:09 PM andypugh: It’s not particularly practical in the context we are discussing.
04:09 PM XXCoder: looks like resposible and attenative driving ;)
04:09 PM MarcelineVQ: *route for wildfires
04:10 PM XXCoder: andypugh: love the classic one tho!
04:10 PM MarcelineVQ: andypugh: I've got that as a christmas ornament :>
04:11 PM andypugh: XXCoder: I am clearly showing someone a number, but I have no idea where or when
04:12 PM XXCoder: was it voting stuff? well gonna go to work katers
06:56 PM Lcvette: is it normal for some systems to not use the index signal from axis servos on feedback?
06:57 PM Lcvette: this little mchine does not show the index signal going to the controller for x and z, only for the spindle
06:57 PM * Lcvette uploaded an image: Rhino DB50 Pinout.png (97KB) < https://matrix.org/_matrix/media/v1/download/matrix.org/iXEuCfxlalKEszSsInzZQLxN >
06:58 PM Lcvette: this is the only connector that connects the lathe to the controller, it is a 50 pin DB50 connector
07:01 PM andypugh: If you trust the home switches then it is pretty common to ignore the axis indexes
07:02 PM andypugh: They can give you a more accurate home, but that is all they are good for.
07:04 PM Lcvette: ok
07:06 PM Lcvette: i suppose i trust them?
07:06 PM Lcvette: lol
07:07 PM Lcvette: never used this machine before
07:07 PM Lcvette: lol
07:08 PM gregcnc: If the mfg did i suppose you could
07:08 PM andypugh: It matters if you want to shut the machine down and continue a job the next day.
07:08 PM gregcnc: right, check the homing when you get it running and index if you like
07:08 PM andypugh: Otherwise you might be better saving the pins for other jobs.
07:10 PM gregcnc: that bit you posted yesterday said somehting about 3 index signals/rev on the spindle?
07:11 PM Lcvette: yeah, the spindle encoder is overdriven 3:1 so i will just make it a 1:1 belt ratio
07:11 PM Lcvette: that should resolve that issue
07:11 PM gregcnc: what is resolution?
07:12 PM Lcvette: no clue
07:12 PM gregcnc: probably plenty
07:12 PM Lcvette: couldn't find anything in the literature i have on it
07:13 PM Lcvette: i would think so?
07:13 PM Lcvette: although it is pretty tiny
07:14 PM gregcnc: that setup just seems odd
07:15 PM Lcvette: yeah
07:15 PM Lcvette: not sure if they had threading even back then on it
07:15 PM Lcvette: certainly not rigid tapping
07:15 PM Lcvette: so it may have just been used as a tachometer
07:15 PM Lcvette: but im not sure
07:18 PM Lcvette: ```
07:20 PM gregcnc: Is the mill making parts?
07:20 PM Lcvette: no
07:21 PM Lcvette: still working on the gui
07:22 PM gregcnc: did you get closed loop stepper working?
07:24 PM Lcvette: got it working, but it ran pretty rough that way
07:24 PM Lcvette: ended up going back to open loop
07:24 PM Lcvette: was servos
07:25 PM gregcnc: oh that's right
07:25 PM gregcnc: there was a YT recently about closed loop steppers
07:46 PM Lcvette: yeah?
08:40 PM {HD}: Anyone have a foss dwg/svg/dxf to R12_dxf converter? I found draftsight but requires a net activation and this comp no net...
08:42 PM Tom_itx: foss?
08:42 PM MarcelineVQ: free open source software
08:45 PM weenerdog: howdy
09:11 PM {HD}: What MarcelineVQ said
10:28 PM jesseg: Howdy
10:29 PM infornography: lo
10:44 PM Tom_itx is now known as Tom_L
