12:00 AM rtagro: i just want to get linuxcnc running as simple, cause i got couple of servo motor and driver sitting on table and just wanna see it turn
12:08 AM Rab: Pretty sparse, but surely there are more working cards.
12:26 AM rtagro: https://hackaday.com/2017/05/05/converting-parallel-port-cncs-to-usb/
12:27 AM rtagro: i borrow a freinds computer and on his mother board he has serial to paralle and the connector, so in all i just need the breakout board ?
12:31 AM Valen: CaptHindsight: Noctua are the best brand I know of for fans btw
12:31 AM Valen: if you're after long life in harsh conditions you can get their sealed ones
12:34 AM Valen: how bad is it to run the mesa ethernet stuff through a switch out of curiosity?
01:20 AM CaptHindsight: Valen: IIRC PCW mentioned trying to avoid any switches and going direct Nic to Nic
01:21 AM Valen: figured as much, was thinking of using a NUC to run it all, single ethernet only
01:21 AM Valen: guess it has wifi though
01:21 AM CaptHindsight: low enough latency switch should not be an issue
01:21 AM CaptHindsight: if you find one
01:21 AM CaptHindsight: then agin in 2026 we'll be joking about how slow the networks used to be
03:13 AM pink_vampire: rtagro: just get C10 board
03:18 AM pink_vampire: https://www.ebay.com/itm/153437746514
05:10 AM Tom_L: morning
05:10 AM XXCoder: yo
05:39 AM jthornton: morning
05:40 AM XXCoder: hey
05:57 AM Valen: did andypugh have any luck getting a more up to date linux working?
06:04 AM jthornton: for?
06:04 AM XXCoder: linuxcnc wild guess
06:06 AM jthornton: rtai, rt preempt etc
06:09 AM Valen: Either I guess
06:10 AM Valen: Rtai would be nice but that didn't seem to be going well
06:10 AM jthornton: well he fixed the broken wheezy repositories for rtai
06:10 AM jthornton: https://forum.linuxcnc.org/29-forum-announcements/36691-fixing-wheezy-repositories#135195
06:11 AM jthornton: for rt preempt I have full instructions to build that on the OS of your choice here
06:11 AM jthornton: http://gnipsel.com/linuxcnc/uspace/index.html
08:13 AM Loetmichel: *GNAH* today is my offday... just got a call from the security company: break-in message from the Alarm system at the company... so i drove 15 minutes to the company, opened a window, closed it, reset the Alarm, armed the Alarm system again, drove home. Didnt even arrive home before the next call from the security company... That sensor has a lose contact for close to 3 years now... the
08:13 AM Loetmichel: Alarm system installing company cant find it. :-(
08:14 AM Loetmichel: ... and boss is on mallorca for the weekend... so i have to drive there and reset the system every time :-(
08:15 AM x2s: Well, on the positive side you have one more day of vacation now ;)
08:17 AM Loetmichel: x2s: dreamer.
08:23 AM jthornton: yea creating parts on the fly in my plasma gui
08:56 AM Tom_L: and i thought you cleaned the bugs out of it :)
09:05 AM jthornton: the plasma I'm just starting to add stuff like that to it
09:11 AM Tom_L: using the qtpyvcp for it?
09:16 AM JT-Shop: yea
09:16 AM Tom_L: nice
09:17 AM Tom_L: did you have to upgrade the MB & OS for that?
09:18 AM JT-Shop: you need debian 9 or lubuntu 18 or linux mint 19 I've not tried linux mint tho
09:19 AM Tom_L: that's why i asked... i knew you needed at least debian 9
09:19 AM Tom_L: dunno what lubuntu is
09:22 AM JT-Shop: light weight ubuntu I actually get a huge reduction in latency with lubuntu
09:22 AM Tom_L: will it work on old hardware?
09:22 AM Tom_L: d525 for example
09:23 AM Tom_L: i have my doubts...
09:23 AM JT-Shop: https://forum.linuxcnc.org/9-installing-linuxcnc/36609-lubuntu-18-04
09:23 AM JT-Shop: lubuntu has versions that run on a 486 IIRC
09:25 AM Tom_L: not on your build page yet is it?
09:26 AM JT-Shop: the plasma one?
09:27 AM Tom_L: for building OS for linuxcnc
09:27 AM JT-Shop: http://gnipsel.com/linuxcnc/uspace/index.html
09:27 AM JT-Shop: yes
09:30 AM Tom_L: i might give that a try later
09:42 AM mozmck: lubuntu uses LXDE which is one of the lightest DE's I believe that is what is (or was) default in raspbian
09:42 AM mozmck: and other distros for low-end hardware.
09:43 AM Tom_L: does it support mate?
09:43 AM mozmck: you mean the mate desktop?
09:43 AM Tom_L: yes
09:44 AM mozmck: lxde is a competing desktop - but lighter weight.
09:44 AM Tom_L: ok
09:44 AM mozmck: You can install multiple desktops on any distro though and pick the one you want to run when you log in.
09:45 AM mozmck: So in any *buntu there are meta-packages that will install other desktops - kde, gnome, xfce, etc.
09:46 AM mozmck: https://lxde.org/
09:46 AM Tom_L: i'd rather not have to pick each time i boot
09:47 AM mozmck: It's at login, and at least with the login managers I've used they remember the last option.
09:49 AM mozmck: If you don't like LXDE though then you can just install ubuntu-mate or whatever and pretty much the only difference is the default desktop that gets installed. Lubuntu just installs LXDE by default.
09:52 AM mozmck: I suspect the biggest reason JT-Shop saw much better latency with Lubuntu had more to do with the fact that he compiled a much newer kernel, and the default options are probably different than the debian RT kernel as well.
09:54 AM Tom_L: the mill is running wheezy which works fine. i just thought i might see if a newer OS would work on that old junk (D525)
09:54 AM jthornton: yea I used the rt kernel that was in the debian repo
09:54 AM mozmck: Are you using preempt-rt or RTAI?
09:55 AM Tom_L: RTAI
09:55 AM Tom_L: switching to lbuntu would be preempt-rt though i suspect
09:55 AM mozmck: hey jthornton: I saw that - it it 4.9.x and the one you compiled for Lubuntu is 5.0.x with a default config.
09:55 AM mozmck: Tom_L: parport or mesa card?
09:56 AM Tom_L: parport using mesa 7i90?
09:57 AM mozmck: Ah. Can that be used with preempt-rt?
09:57 AM Tom_L: i will keep the original ssd install separate
09:57 AM Tom_L: no clue
09:57 AM mozmck: pcw_home would know
09:57 AM Tom_L: that's why you guys get paid the big bux
09:57 AM Tom_L: :)
09:59 AM JT-Shop: now I gotta build the same kernel for debian and test that out
09:59 AM mozmck: heh!
09:59 AM JT-Shop: I use riot also
09:59 AM mozmck: It would be interesting to see how that works.
10:00 AM Tom_L: what is riot?
10:00 AM mozmck: Apparently it's a frontend for chat server(s)?
10:01 AM JT-Shop: irc client for the matrix
10:01 AM mozmck: Is riot only on the web or are there standalone clients as well?
10:01 AM Tom_L: ahh yeah i remember Lcvette trying to get me on that
10:02 AM JT-Shop: I use a stand alone version and also use it on my phone
10:02 AM mozmck: Somehow it connects to the #hazzy IRC channel through the matrix server.
10:03 AM JT-Shop: I think either Kurt or turboss did that
10:04 AM JT-Shop: https://riot.im/download/desktop/
10:06 AM mozmck: Interesting. So do you have to register with riot.im to use it for IRC? Do you need an IRC nick as well? I should probably ask TurBoss
10:11 AM narogon: hi everyone
10:12 AM narogon: I've bought an industrial keyboard and I'm experimenting bounce while I jog
10:12 AM narogon: after a while (1 or 2 seconds) the signal from the keyboard start to bounce
10:13 AM narogon: If i do a scope of motion. kb jog active I can see how it goes on and off repeatly. If I connect my old keyboard it doesn't happen.
10:13 AM narogon: any idea of how debounce a keyboard???
10:14 AM Roguish: get a new keyboard...
10:14 AM Tom_L: or use the old one
10:14 AM Tom_L: ps2, usb wireless?
10:15 AM narogon: the problem is that I've bought this because is industrial... made of steel...
10:16 AM narogon: it has a ps2 to usb converter
10:16 AM Tom_L: mine is the cheapest plastic thing i could find... i paid $3 for it
10:16 AM narogon: old mine are always the cheapest
10:16 AM Roguish: Cherry makes good, industrial keyboards, a bit pricey, but very good.
10:16 AM narogon: but this one is made of steel and ip67
10:17 AM Tom_L: you can't beat cherry key switches
10:17 AM Tom_L: i'm still using an old omnikey 102 on an old p100
10:17 AM narogon: I've use the evtest and check that after a while appears a MSC_SCAN event
10:17 AM narogon: that the other keyboard doesn't send
10:18 AM Deejay: hi
10:19 AM mozmck: I have some Unicomp keyboards and they are junk. I had a couple of brand new ones, and after a while keys just quit working. I don't know if the key switches are cherry though.
10:20 AM Tom_L: i finally desoldered one from the omni and fixed it
10:20 AM mozmck: I think the probably is not the key but the chip or something.
10:20 AM Tom_L: reseat the chip
10:20 AM mozmck: Hmm, that's an idea.
10:20 AM Tom_L: they build corosion on the plug after a century or so
10:20 AM Nick001-shop: Is there a mastercam post script for linuxcnc lathe?
10:21 AM Tom_L: mozmck, the problem with mine was a cold solder joint as it turns out
10:21 AM Tom_L: check that too
10:22 AM mozmck: These were new though - made in 2010 and they aren't cheap: https://www.pckeyboard.com/page/product/UNI0P46
10:22 AM mozmck: I did find numbers of reviews stating that other had the same problem with these keyboards. Fortunately I bought mine at an auction for a couple dollars each NIB
10:27 AM Roguish_ is now known as Roguish
10:27 AM narogon: the keyboards runs well
10:27 AM narogon: in general
10:27 AM narogon: but if you press an arrow continuosly
10:27 AM narogon: it start to turns off an on
10:27 AM mozmck: narogon: keyboard jogging is done in the python code I think.
10:27 AM narogon: mozmck could you guide me to the py file
10:27 AM narogon: I could make a debouncer there...
10:27 AM narogon: maybe wait 0,1 seconds to turn off the jogging
10:28 AM mozmck: Are you using the Axis interface?
10:31 AM narogon: yes
10:33 AM narogon: yes mozmck I'm using axis
10:36 AM mozmck: Well, the code is down in src/emc/usr_inft/axis
10:37 AM mozmck: I'm pretty sure it would be better to figure out what is wrong with the keyboard or keyboard driver though.
10:39 AM Tom_L: ok at least i got lbuntu downloaded...
10:39 AM Tom_L: gotta go run some errands
10:41 AM narogon: mozmck the differences between a keyboard that doesnt bounce
10:41 AM narogon: and this one is
10:41 AM narogon: (using evtest) that this after 2 seconds sends a MSC_SCAN event each EV_KEY one
10:42 AM narogon: the correct one only sends EV_KEY EVENTS
10:42 AM narogon: that the only difference i've found
10:47 AM mozmck: I don't know enough about that. Not sure where in the python code you would look to see what it is responding to. It may not get the low level usb events.
10:50 AM narogon: maybe cradek or seb_kuzminsky know something more
10:50 AM narogon: and can help
11:06 AM cradek: try plugging it into a real ps2 keyboard port. many of those ps2/usb convertors do strange things.
11:09 AM cradek: one time I tried about six brands of convertor before I found one that worked adequately, and it was still never quite right
11:16 AM narogon: cradek I can't the ps2/usb converter is inside the keyboard, there is no ps2 port
11:18 AM narogon: I think the easiest way is to implement a debounce in the catch key press program
11:19 AM narogon: or maybe create pins for keypressed and make the debounce in hal component
11:28 AM mozmck: I found lib/python/linux_event.py and src/hal/user_comps/hal_input.py which deal with low level EV_KEY and such events, but I can't find that they are used anywhere?
11:39 AM gregcnc: has anyone posted this? Colchester Lathe Manufacture https://youtu.be/nQaAKUAzK0w
12:20 PM CaptHindsight: gregcnc: that video is old and obsolete, everything is "overbuilt" and expensive
12:27 PM CaptHindsight: https://youtu.be/cEfhDqMup2Y?t=995 came out pretty wobbly
12:30 PM Tom_L: jthornton, once i install lbuntu 18, do i need a key or something to add linuxcnc to the distro list in the package manager?
12:30 PM FinboySlick: gregcnc: I like how they didn't have reliable imagery of earth from space back then so they just filmed a spinning globe.
12:30 PM Tom_L: (just finished burning the disk)
12:32 PM FinboySlick: That british accent though... Wow.
12:33 PM CaptHindsight: FinboySlick: would be funny to have a spinning flat map for those in the dark
12:44 PM gregcnc: some people have got milking social media for money down to an art
01:17 PM andypugh: “We’re making a film lads, paint all the machine tools gold”
01:22 PM CaptHindsight: andypugh: with RTAI out of the way why not just post LCNC packages?
01:23 PM andypugh: We should probably do that too. But are packages distribution-specific?
01:30 PM CaptHindsight: yes
01:31 PM CaptHindsight: but then LCNC can run on Fedora, Gentoo etc
01:32 PM CaptHindsight: vs just forms of Debian or Linux like systems such as ubuntu :)
02:41 PM Tom_L: jthornton
02:42 PM Tom_L: on your lbuntu page on line: wget https://mirrors.edge.kernel.org/pub/linux/kernel/projects/rt/5.0/patch-5.0.14-rt9.patch.gz
02:43 PM Tom_L: i get 404 not found
02:46 PM Tom_L: moved to 'older' directory
02:46 PM Tom_L: newer patch is available
02:49 PM Deejay: gn8
02:51 PM Tom_L: Deejay
03:30 PM andypugh: Tom_L: You probably don’t need patches. There is likely to be a package in Synaptic: For example Stretch shows : linux-image-4.9.0-9-rt-amd64
03:30 PM JT-Shop: yea sometimes you just have to navigate to the patch
03:31 PM andypugh: Go into the synaptic gui, search for “realtime” and scroll down looking for “linux-image”. See what you find.
03:35 PM pink_vampire: what do you think about replacing my y axis bearing with 2 of those https://www.ebay.com/itm/130572952532
03:38 PM pink_vampire: now I have 1 3201-2RS bearing https://www.fastenal.com/product?query=3201-2RS&fsi=1
03:45 PM jthornton: andypugh: I didn't find any realtime kernels packaged with Lubuntu
03:46 PM Tom_L: i found it, just letting you know about the update
03:47 PM Tom_L: still building atm
03:49 PM gregcnc: pink_vampire if you can make a pair fit, use them the 3201 is not preloaded, but the pair can be
03:51 PM gregcnc: the 7201 you linked is not a matched pair though. preload is in the micron range for a back to back set.
03:52 PM Tom_L: usually cost alot more too
04:28 PM andypugh: You can arrange for preload in the housing design, though. Or simply make paper shims.
04:41 PM perry_j1987: interesting
04:42 PM perry_j1987: just seen someone bolt some gang tooling to side of mill head and a rotary axis on their mill
04:42 PM gregcnc: it works
04:43 PM XXCoder: heh I remember seeing one shop I was being interviewed at but ultimately didnt get work at - they used dermel attached to spindle.
04:44 PM XXCoder: so they could do 90 degree holes
04:44 PM XXCoder: part was otherwise completely doable in normal 2.5 dimension mill machine
04:50 PM CaptHindsight: XXCoder: sideways holes?
04:50 PM CaptHindsight: on a vertical mill?
04:50 PM XXCoder: yeah
04:50 PM CaptHindsight: without flipping the parts 90 deg
04:50 PM XXCoder: part was pretty big
04:50 PM XXCoder: no way to do that
04:51 PM XXCoder: all kinds of angles too so they used spindle as 4th axis to rotate tool to match angles.
04:52 PM XXCoder: kinda glad I wasnt hired there lol
04:52 PM XXCoder: shop was quite dark
04:52 PM XXCoder: messy and floor was dirty'
04:52 PM XXCoder: my current place is much nicer
04:53 PM CaptHindsight: Lazy Susan bearings, wonder if we need a more PC term for this?
04:54 PM CaptHindsight: work-shy susan
04:54 PM XXCoder: dunno
04:54 PM XXCoder: off to normal pay overtime work I go whee
05:15 PM pink_vampire: andypugh: https://i.imgur.com/ZB1IY9i.png this is the design
05:15 PM pink_vampire: what do you think?
05:17 PM andypugh: Exactly what I had in mins
05:17 PM andypugh: (mind)
05:17 PM andypugh: So you preload with the nut to the required degree.
05:17 PM Tom_L: mmm i should have built this kernel on something beside a d525
05:17 PM andypugh: I assume where you have “bolt” you mean a bolted-on cover?
05:20 PM pink_vampire: I mean like mushroom head screws
05:20 PM andypugh: Hmm, that would work but look ugly.
05:21 PM andypugh: Do you have a lathe?
05:21 PM pink_vampire: this is how it work now
05:21 PM pink_vampire: yes
05:21 PM pink_vampire: https://i.imgur.com/deAKoKz.png
05:21 PM andypugh: I would have the housing a little deeper than the bearings, and then a cover plate that fits in to the bearing bore, with a flange for screws.
05:21 PM pink_vampire: you see the place for the 4 screws
05:22 PM andypugh: Ah, OK, if it alread works that way, then don’t change it
05:22 PM pink_vampire: i have 0.3mm of play (backlash) in the Y axis
05:23 PM andypugh: That’s probably more than you want.
05:23 PM pink_vampire: maybe I also need a new ballnut?
05:23 PM pink_vampire: andypugh: it is in the point of unusable
05:24 PM andypugh: You could try clamping the screw tight (somehow) to measure the ballnut backlash.
05:26 PM pink_vampire: not sure how
05:27 PM andypugh: No, I was vague on that too.
05:28 PM andypugh: push it all the way back onto the machine with a bar clamp so it is ard against the back casting?
05:38 PM pink_vampire: I'm trying
05:38 PM pink_vampire: for 4-5 years maybe it is time to replace ballnuts?
05:39 PM andypugh: no real reason to expect so, they last that long in full-time production machines.
05:40 PM pink_vampire: but on my machine the dovetails are sooo snugs that the ballnut take abit of abuse over time
06:31 PM jthornton: pink_vampire: my VMC is ~80's or so (uses a 386 processor) and still has the original ballnut but you say dovetail and that doesn't sound very industrial anymore
07:55 PM justan0theruser is now known as justanotheruser
09:13 PM perry_j1987: evening all
09:13 PM Tom_L: evening
09:22 PM perry_j1987: rotary axis on mill and 60degree v bit produce threads well?
09:25 PM Tom_L: i dunno, i wouldn't bet on it
09:25 PM Tom_L: i played around with thread mills a while back
09:26 PM Tom_L: wrote a macro for my cad cam to generate them
09:26 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/thread_mills/Thread_mill2.jpg
09:27 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/thread_mills/Mill_Holder_Steel1.jpg
09:27 PM Tom_L: pretty good results i think
09:27 PM Tom_L: side hole and top were both thread mills
09:28 PM Tom_L: i would think a v bit may chatter quite a bit and take forever to cut it
09:28 PM Tom_L: never tried it though so meh
09:29 PM Tom_L: with those you can cut internal or external threads
09:29 PM perry_j1987: ya i'd like to get some to play with
09:29 PM Tom_L: in the US?
09:29 PM perry_j1987: I have this rotary axis i want to start playing with and looking for options
09:29 PM perry_j1987: ya
09:29 PM Tom_L: http://onlinecarbide.com/sipithmi.html
09:30 PM Tom_L: i can do a wide range of threads with those
09:30 PM perry_j1987: alot of pucker factor heh
09:30 PM perry_j1987: plunging into small holes
09:30 PM Tom_L: naw
09:31 PM Tom_L: that's why i did the macro so i wouldn't screw up next time i need one
09:31 PM perry_j1987: i want to do some metric holes
09:32 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/threadmacro6.jpg
09:32 PM Tom_L: just some tests i did on the cad cam
09:32 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/threadmacro1.jpg
09:33 PM Tom_L: i program to the tool tip so i know where it's gonna end up at the bottom
09:34 PM perry_j1987: ah so not the point of the v then?
09:35 PM Tom_L: on the diameter it does but not the depth
09:35 PM Tom_L: and it will do multiple pass adding lead in lead out moves
09:35 PM Tom_L: depending on if it's internal or external threads
09:36 PM perry_j1987: whats the smallest one you've used
09:36 PM Tom_L: 10-32
09:36 PM Tom_L: the one you see in the pic
09:36 PM Tom_L: the other one was 3/4 16
09:37 PM Tom_L: i didn't think i would need anything smaller than that
09:37 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/threadmacro_multipass2.jpg
09:37 PM Tom_L: just shows multiple pass for both thread types
09:38 PM Tom_L: typically i wouldn't do more than 3 passes
09:39 PM Tom_L: i also changed the lead in moves to arcs in the final iteration of it
09:39 PM perry_j1987: i seen a guy on youtube with bunch of sherlines doing some super tiny threadmills
09:39 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/arc_leadin_percent.jpg
09:40 PM Tom_L: that link sells them down to #0 80
09:46 PM Tom_L: perry_j1987, when i had my sherline working i tried rigid tapping with it
09:46 PM perry_j1987: how'd it go
09:47 PM Tom_L: the spindle needs more power to do it right but it worked
09:48 PM Tom_L: https://www.youtube.com/watch?v=g99lUtjLfMU
09:54 PM Tom_L: i did it more for a test of spindle / axis sync
10:10 PM rtagro: can someone help i want to install packges but keep giving me erroe unable to locate package
10:10 PM rtagro: its fustrating
10:15 PM pink_vampire: yes
10:15 PM pink_vampire: rtagro:
10:16 PM pink_vampire: what are you tying to install?
11:01 PM rtagro: pink_vampire, ranger file mananger
11:02 PM rtagro: and hex chat
11:02 PM rtagro: im using my hex chat on arch distro
11:04 PM Tom_L: what os?
11:06 PM Tom_L: you might have to use backports if it's older
11:10 PM pink_vampire: rtagro: try apt-get update
11:13 PM rtagro: pink_vampire, i did that didnt help
11:15 PM rtagro: could I add differnt linux distro repository example ubuntu, will that work ?
11:15 PM pink_vampire: what is the error?
11:15 PM Tom_L: what distro are you working with?
11:16 PM rtagro: im using chat on Arch
11:16 PM rtagro: ive set my system dual boot
11:16 PM pink_vampire: LOL
11:17 PM rtagro: yea pretty much
11:18 PM rtagro: Im new to linux
