01:25 AM Deejay: moin
02:19 AM Loetmichel: hey, fellow machinists... any idea if 50mm diameter hadles/cranks instead of 34mm (diameter will do better ton the "moving around" part while using my minilathe? just found 2 blocks of 7075 alu that would fit 50mm crank handles... (that 'machine': -> https://www.youtube.com/watch?v=7J40p8dMZZk&t=37s )
04:18 AM XXCoder: blackhole
05:08 AM jthornton: morning
05:09 AM XXCoder: yo
05:11 AM Tom_L: hey
05:12 AM jthornton: raining pretty hard here
05:12 AM XXCoder: it havent rained for couple weeks here
05:12 AM XXCoder: and wont for another week. not good. its normally raining like someone up there forgot to turn off facet
05:13 AM XXCoder: normally I would have forgotten what color dry roads are months ago
05:20 AM Tom_L: light rain right now but steady for last couple days
05:23 AM jthornton: got one more can light to remove from over the sink and change it to LED, what a PIA to work on
05:24 AM Tom_L: kitchen remodel?
05:24 AM jthornton: no, bulb burned out and one buzzed real loud so time to fix them
05:25 AM XXCoder: nice I love led lighting
05:25 AM XXCoder: this house is entirely led
05:25 AM Tom_L: i like the daylight ones
05:26 AM Tom_L: got em in the house and put strips in the garage
05:26 AM Tom_L: humidity out there kept screwing with the flourescent ones
05:27 AM jthornton: I'm slowly converting all the garage, machine shop and big shop to led
05:27 AM Tom_L: same here as they die
05:27 AM XXCoder: ironically we converted old house to all leds but kept old lights
05:28 AM XXCoder: when we moved here, we got all led lights back with us
05:28 AM XXCoder: intending to convert this house too... but it was all led already lol
05:35 AM jthornton: I also figured out that the el cheapo 4' shop lights can't be converted to run without a ballast nor will they power up the led tubes
05:36 AM XXCoder: bleh
05:36 AM XXCoder: costco used to have cheap ones. not sure if still.
05:36 AM XXCoder: here at tacoma we can buy em half price before but dunno if still.
05:46 AM Loetmichel: XXCoder: our new CEO just ordered a dozen 40W led panels from a surplus shop.... 4.95 eur each... just were delivered today to the company... MAAAN where to put that stuff?
05:47 AM Loetmichel: every panel in its own carton /shipping package ;)
05:47 AM XXCoder: 5 euro each!
05:47 AM XXCoder: how good is it? is it like workshop forsecent panel?
05:47 AM XXCoder: 4 light tube type
05:49 AM XXCoder: ah surplus no wonder so cheap[
05:49 AM XXCoder: so whats plan with it?
05:51 AM jthornton: hmm what is the range for a u32 number?
05:53 AM Loetmichel: cant find ti on pollin.de any more.
05:53 AM Loetmichel: was a panel to fit in thosuspended ceiling tilesse
05:54 AM Loetmichel: tiles
05:54 AM Loetmichel: grrr those suspended ceiling tiles
05:55 AM XXCoder: pretty nice
05:56 AM Loetmichel: still: i think the PSU you need for them will be 10 times more expensive
05:56 AM Loetmichel: than the panel itseld ;)
05:56 AM Loetmichel: its 30V 1,2A ;)
05:56 AM XXCoder: fun lol
05:57 AM Loetmichel: at least he warned me monday. "ah, btw: couldnt restrain myself, expect a big delivery from Pollin soon!"
05:57 AM Loetmichel: :-)
05:58 AM Loetmichel: he is "not yet" oru CEO, company is in the process of being soldt. with him as the new boss, but we are not there yet, he only comes by every few weeks to help out
05:58 AM XXCoder: hopefully transition goes well
05:59 AM XXCoder: here highest chance of disabled or deaf workers getting fired is some dumbass new manager needing to show that he or she can fire people.
06:01 AM Loetmichel: found it. "downlight" https://www.pollin.de/p/led-einbauleuchte-toshiba-e-core-led-downlight-6000-eek-a-weiss-533913
06:01 AM Loetmichel: and even more power than i thought
06:01 AM Loetmichel: the other panels he ordered last time were those 40*40cm stuff that fits a ceiling tile
06:01 AM Loetmichel: not downlights
06:01 AM XXCoder: 5650 lumen yeah thats some power
06:01 AM Loetmichel: (just opened one of the cartons) ;)
06:03 AM Loetmichel: and dirt cheap. but 42 V tiomes two is a bit odd ;)
11:02 AM fl0rene: hello, i decided to install the iso of linuxcnc-stretch-uspace-amd64-r13 to try the qtvcp ui but i can't find the option to select qtvcp in the list of sims. did i miss something???
11:08 AM Tom_L: fl0rene you mean QtPyVCP?
11:08 AM Tom_L: i don't think that's part of the iso if that's what you're after
11:09 AM Tom_L: maybe: http://linuxcnc.org/docs/devel/html/gui/qtvcp.html
11:25 AM fl0rene: Tom_L: saw that on youtube, but it is a german video https://www.youtube.com/watch?v=ZVYKa0ycNog and he downloaded the iso from http://www.linuxcnc.org/testing-stretch-rtpreempt/ with rtpreempt kernel!
11:28 AM fl0rene: he explains that he only installed the iso and all is running fine including qtvcp!!
11:28 AM Tom_L: read the linuxcnc doc i posted
11:29 AM Tom_L: i installed the devel environment on mine
11:30 AM Tom_L: http://gnipsel.com/linuxcnc/uspace/index.html
11:30 AM Tom_L: you can follow that and install whatever you wish
11:34 AM fl0rene: thanks a lot, i'll read though and give it a try!! thanks
11:36 AM Tom_L: i installed stretch and preempt-rt that way
11:37 AM Tom_L: i wanted the mate desktop and that's not the default for the iso
12:20 PM skunkworks: https://youtu.be/F7QulGiMt20
12:20 PM skunkworks: (just the tapping video0\)
12:21 PM Rab: skunkworks, is that a forming tap?
12:23 PM skunkworks: No - normal tap - shavings go out the hole.
12:23 PM skunkworks: (down in this video)_
12:44 PM jthornton: fl0rene: qtvcp is only in master (2.8) the iso will be 2.7
01:14 PM pink_vampire: skunkworks: very nice!!
01:27 PM andypugh: I have a project that will require me to tap 3000 holes in an aluminium plate. I think I will rigid-tap them.
01:29 PM skunkworks: I would... the hard core manual people say they can tap with a tapping head on the drill press faster
01:30 PM SpeedEvil: Or just drill to the proper diameter and use an impact to install bolts.
01:30 PM Rab: skunkworks, but probably not while doing something else? ;)
01:33 PM skunkworks: well people don't think of that...
01:42 PM JT-Shop: I think a tapping arm is faster than a drill press and a tapping head
01:43 PM cradek: wow that's fast
01:43 PM JT-Shop: my buddy has one and it's lightning fast
01:44 PM JT-Shop: I think it's faster because you don't move the material being tapped
01:45 PM syyl: handheld tapping machine.
01:45 PM syyl: look like a handdrill but have mechanical autoreverse if you pull on the tap
01:45 PM syyl: its like a handheld tapmatic ;)
01:45 PM JT-Shop: this one looks like a drill on a arm
01:46 PM JT-Shop: maybe I can sell Andy my tapmatic head...
01:46 PM JT-Shop: then he can mount it to his Faro arm...
01:47 PM syyl: marketing opportunity
01:47 PM syyl: a cmm that can do tapping
01:47 PM syyl: i guess that makes sense
01:48 PM Rab: skunkworks, for that tapping setup, is your spindle servoed w/encoder feedback?
02:55 PM andypugh: A tapping head on a Faro arm could tell you if you were at the correct angle for that particular hole.
02:55 PM andypugh: So there is a possible application.
03:20 PM JT-Shop: andypugh: is there any reason you know of to not increase the tool table limit to 256 like eusurplus is doing?
03:21 PM JT-Shop: http://www.wiki.eusurplus.com/index.php?title=Useful_linux_commands#Tool_table_limit_.28257_instead_of_56.29
03:21 PM JT-Shop: only two lines changed!
03:22 PM JT-Shop: err 257 pockets
03:35 PM andypugh: It makes the NML messages very big. (apparently)
03:36 PM andypugh: rene_dev_: Might know more than me, he’s been looking at tool table
03:36 PM andypugh: (Having any limit at all seems like a mistake, tool changes will always break blending, so why does realtime need more than one tool at a time?)
03:40 PM jthornton: that's a good question
03:41 PM jthornton: now if I can figure out a way to trap these damn gnats that have invaded my basement...
03:42 PM XXCoder: andy sometimes we use 2 D values for one tool for blending better
03:42 PM XXCoder: but yeah load only when it detects T H or D
03:46 PM skunkworks: Rab: yes- the spindle is a brushless servo with encoder feedback - strictly for velocity control.
03:46 PM skunkworks: There is an encoder on the spindle that does the rigid tapping/spindle synced motion
03:52 PM Deejay: gn8
04:52 PM jthornton: hmmm the linuxcnc wiki is down
04:57 PM jthornton: lol
05:26 PM andypugh: Rab: Hope they weren’t using LinuxCNC :-)
05:27 PM _unreal_: ?
05:27 PM Rab: andypugh, sounds like it was the factory Haas control.
05:29 PM jthornton: what was the video about?
05:29 PM andypugh: I would suggest watching it.
05:34 PM jthornton: wow
05:34 PM gregcnc: that's impressive
05:36 PM infornography: what did I miss?
05:37 PM gregcnc: sketchy controls are terrifying
05:37 PM gregcnc: could have just as easily been an extra 0 though
05:45 PM jym: 11,999 RPM and it would have been fine
05:45 PM jym: 219K views in ten hours, heh
05:59 PM Tom_L: zoom zoom
06:00 PM Tom_L: reminds me of a place i worked at that had a drop hammer press with a big flywheel that broke loose and went thru a concrete block wall
08:26 PM Elmo40: ouch!
08:26 PM Elmo40: inertia is a bitch. ;-)
09:16 PM Valduare: wiki down for everyone else?
10:21 PM Tom_L: it is
10:22 PM cradek: I have or had a login for that machine but so far I've been unsuccessful at figuring out which ssh key it is.
10:24 PM cradek: I think I have the right key (which has a 2011 date on it) but something has changed about the hosting machine that both broke the wiki and broke my login
10:26 PM Tom_L: once recovered, maybe it should be shared with a couple more here
10:26 PM cradek: ... so I think I'm powerless
10:26 PM cradek: I'm not really sure what I'd do once logged in, but I was going to at least troubleshoot
10:26 PM Tom_L: jeppler was doing that wasn't he?
10:27 PM Tom_L: no, that was the forum
10:27 PM cradek: the wiki probably uses a defunct cgi interface module or something
10:31 PM cradek: if he has the same phone number as in 2012, I texted swp asking for help
10:32 PM cradek: ... if not, I texted a random person
