01:33 AM Loetmichel: mornin'
02:01 AM Deejay: moin
02:33 AM miss0r: https://www.youtube.com/watch?v=k4lUmE945js 1940's handscraping
02:33 AM miss0r: sadly, threes no sound
02:34 AM miss0r: oh there is.. just very low
03:20 AM gloops: right, 6 months behind schedule with this, time to build a bandsaw
03:23 AM Blumax: hello
03:23 AM Blumax: JT-Shop, I did everything you asked me
03:24 AM Blumax: http://prntscr.com/l2fusv
03:25 AM Blumax: I have the small target
03:26 AM Blumax: dmesg : https://pastebin.com/4VQDCvwA
03:27 AM Blumax: For dmesg, I have empty dmesg. Start LinuxCNC. Homing. Move with handwheel. Close LinuxCNC.
03:40 AM gloops: error message on closing?
03:42 AM Blumax: no error on close
03:48 AM gloops: so the linuxcnc window just disappears? it doesnt detail the closing sequence
04:04 AM Blumax: Where can we see the detail of the closing sequence ?
04:05 AM gloops: its in the linuxcnc window
04:06 AM gloops: you will see some data roll up as it closes, if theres an error it will show there
04:06 AM Blumax: I close by clicking on the cross. It does not close all alone.
04:07 AM gloops: ahh right, i thought you meant the handwheel was forcing linuxcnc to close
04:07 AM Blumax: No there is no window after. Just a window asking to validate the clos
04:07 AM gloops: ok
04:07 AM Blumax: No, I just wanted to clarify that I was doing the complete procedure :)
04:27 AM pingufan: Hello. I am running Ubuntu 8.04 - 32 Bit - on my CNC mill (a special realtime version for linuxcnc. I want to add x11vnc because the built-in VNC server is crap.
04:27 AM pingufan: How can I install x11vnc? Can somebody help me, please?
04:30 AM XXCoder: could you add repos for it? or just directly download and install?
04:31 AM pingufan: I have absolutely no experience with Ubuntu (I usually use suse).
04:32 AM XXCoder: video on youtube: Make tool for wood cutting out of useless steel wheel. Banner says "these guys build fitness equipment using only primative tools and materials" and they use reasonable modern steel wheel, angle grinder and arc welder.
04:32 AM XXCoder: yeah just like cavemen
04:32 AM pingufan: At least, "apt-get update + apt-get install x11vnc" leads into "could not find packet x11vnc".
04:33 AM pingufan: No idea how to add repos and install any software.
04:33 AM Loetmichel: that may be beacuse 8.04 isnt supported any more
04:33 AM Loetmichel: install a more recent version
04:34 AM pingufan: A newer version does not support my hardware. I tried in the past.
04:35 AM Loetmichel: i doubt that
04:35 AM pingufan: Or can I get the built-in vnc operational on this old version? I get the first screen copy, but it is nut updating.
04:35 AM Loetmichel: <- has running his CNC on a Core2 duo and latest linuxCNC build
04:36 AM XXCoder: you plan to runb linuxcnc in vm? or something else?
04:36 AM pingufan: ThThen try it on VIA C7 CPU (1-core, 1500 MHz), with OnBoard graphics, 32 Bit. This will change your experience.
04:38 AM pingufan: What I want to do is seeing the desktop on my PC in my office. So I do not have to stand besides the loud machine
04:38 AM pingufan: Have to see the progress to go there when manual interaction will be needed.
04:38 AM Loetmichel: XXCoder: i did the same
04:38 AM XXCoder: oops vnc not vm
04:38 AM Loetmichel: my CNC is remote controlled
04:39 AM Loetmichel: https://www.youtube.com/watch?v=9u_ChO1AKYY&t=35s
04:39 AM XXCoder: man no way to do remote cnc at work lol
04:39 AM XXCoder: I made around 200 parts today
04:39 AM pingufan: My workstation is openSuSE 13.1. The mill is running this Ubuntu 8.04
04:39 AM XXCoder: yeah so much for remote cnc
04:39 AM Loetmichel: a lot less stress when you can sit at the workdesk playing Elite waiting for the CNC to finish
04:40 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=15889 <- :-)
04:40 AM Loetmichel: (after hours of course, misjudged how long that program would run)
04:41 AM pingufan: Well, I enabled remore access in this gnome. But this works lousy.
04:41 AM XXCoder: fun
04:42 AM XXCoder: Loetmichel: typical time of parts I run is in minutes
04:42 AM XXCoder: current record is 3 hours * 2 parts on pallet so 6 hours. but thats pretty rare
04:42 AM Loetmichel: here it is more like hours
04:42 AM pingufan: Can this be tweaked somehow?
04:42 AM Loetmichel: depending on the part
04:42 AM XXCoder: you hiring? lol
04:42 AM Loetmichel: had one that ran 34 hours ;)
04:43 AM Loetmichel: pingufan: i seriously encourage you to update to a newer version of LinuxCNC.
04:44 AM pingufan: As I said, it does not work!
04:44 AM Loetmichel: the internal not workin may well stem from some update missing or a protocol change
04:44 AM XXCoder: ping cant you find better 10 year old pc?
04:44 AM pingufan: If I remember correctly, next version was with Ubuntu 10. No chance.
04:44 AM XXCoder: all it really need is a ok gamer card and very cheap ram since its old
04:44 AM XXCoder: computer recycler center
04:45 AM XXCoder: my pc is 15 years old and runs linuxcnc very well
04:45 AM pingufan: Mine is a bit younger, but not much.
04:46 AM pingufan: Can I increase the update rate through VNC by configuring something on this old Ubuntu?
04:46 AM XXCoder: its pretty easy to upgrade, maybe even find on criaglist, ebay or local computer recycler, or yard sales
04:47 AM XXCoder: heck it can be free if someone has junked computer havent used for years
04:47 AM pingufan: Or where can I find the packages of Ubuntu 8.04 to install manually?
04:48 AM Loetmichel: soe archive site maybe
04:48 AM Loetmichel: but VNC is implying that you have net access... do you REALLY want the machine with THAT old a system acceessible from the internet?
04:49 AM XXCoder: whoa! been a while.farmbot suddenly uploaded 3 videos
04:49 AM pingufan: I currently get one update every 10-20 seconds. Therefore I see no updating at all, because the screen changes too fast.
05:07 AM jthornton: pingufan: I have instructions for keeping 10.04 up to date maybe they might work on 8.04
05:08 AM pingufan: Tell me more, please.
05:08 AM pingufan: What kind of packages does Ubuntu use at all=
05:08 AM pingufan: ?
05:08 AM jthornton: https://mesaus.com/info/lucid-sources.txt
05:09 AM MarcelineVQ: if your system can support it you'd probably have a better time with ssh in X or Y mode than vnc
05:09 AM pingufan: Well, it supports ssh. :)
05:10 AM MarcelineVQ: allthough x11vnc is possibly a similar thing, dunno
05:10 AM pingufan: x11vnc is a vnc server hooking into x11 on very deep level.
05:12 AM pingufan: Can I run the LinuxCNC UI twice (a second time) through a ssh session ?
05:12 AM pingufan: So I have one on the desktop (gnome) and I can use a second one tunneled through SSH to my SuSE KDE desktop?
05:13 AM MarcelineVQ: I've used axis on a remote computer from an ssh -X session on this computer, not sure what you mean by run twice though
05:14 AM pingufan: When I start up the CNC mill , it boots up 8.04 and automatically starts linuxCNC on GNOME. Then I have the UI on the GNOME desktop.
05:15 AM pingufan: If I could launch a separate (second) UI through a SSH login, I wouldn't have to use VNC at all. Then my KDE will display the UI, too.
05:16 AM MarcelineVQ: hmm, I'm not really sure
05:16 AM pingufan: All I need is: I need to see what is going on in the mill.
05:16 AM pingufan: And when I hear a bad noise coming from the mill in the neighbor room, I want to be able to send a "P" for pause.
05:17 AM pingufan: I think about something similar to running a graphical program through ssh
05:18 AM MarcelineVQ: You can do that, I'm not sure about looking at one already running on the remote system, I've never tried
05:19 AM pingufan: The easiest way would be running a properly working vnc server on the mill. But this appears to be problematic. The included one is lousy.
05:19 AM pingufan: (vino-server)
05:20 AM Tom_L: yeah 8.04 is pretty old
05:20 AM Tom_L: what about backports?
05:21 AM MarcelineVQ: looking into it it does look like ssh -X is unsuitable for this task
05:21 AM pingufan: I have absolutely no experience with Ubuntu at all. I was literally forced to use it (by the ISO including linuxcnc at that time)
05:22 AM Tom_L: i'd consider bumping up to 10.04 at least which is also old but works
05:22 AM pingufan: It is my only ubuntu I ever used in my life.
05:22 AM Tom_L: https://launchpad.net/ubuntu/hardy/i386/linux-backports-modules-hardy-generic
05:22 AM pingufan: I tried that. Does not run on my hardware.
05:23 AM Tom_L: what you need might be in the backports, i dunno
05:24 AM Tom_L: https://askubuntu.com/questions/91815/how-to-install-software-or-upgrade-from-an-old-unsupported-release
05:25 AM pingufan: Upgrading is absolutely not possible. :( Even Ubuntu 10 did not support this OnBoard graphics
05:26 AM pingufan: So the only choice is using a repository or archive where I can download the packages from.
05:27 AM XXCoder: my first ubuntu was brown
05:27 AM Loetmichel: pingufan: get a seperate graphics card
05:28 AM Loetmichel: its better anyways for LinuxCNC
05:28 AM Loetmichel: less issues with latency
05:28 AM pingufan: This is a MiniITX mainboard with only one PCI (not PCIe!) socket.
05:28 AM XXCoder: get better one
05:29 AM XXCoder: you probably can find better one free
05:30 AM pingufan: Well, it works fine (except of this remote access issue), so I see no further advantage.
05:30 AM pingufan: What OS is used now for LinuxCNC ?
05:31 AM Loetmichel: advantage would be that you can have a way better working version of LinuxCNC AND a system that has no security issues
05:31 AM Loetmichel: debian
05:33 AM pingufan: I have no problems with security. It is only accessible in my LAN.
05:35 AM pingufan: But what I see more problematic is changing a running system. Every update can cause troubles.
05:42 AM pingufan: Anyway, so I will have to find a different way.
05:44 AM gloops: an old box with a 3d card isnt expensive these days pingufan, worth considering buying one for $20 and update to 2.7, rather than use a dozen hacks to keep an old version alive
05:45 AM pingufan: It's not the question of expensive or not. It is a question of how long can I not use my mill then, how long do I need to set up all that again, ...
05:46 AM XXCoder: if HAL already exists I dont think its a major work
05:46 AM XXCoder: you dont have to instantly throw old one away also
05:46 AM pingufan: It was a nightmare to smoothly embed 8.04 into my systems here. I don't really want to do that again.
05:47 AM pingufan: You mean I take a new PC, install a new linuxCNC, and then copy the old setup to it?
05:47 AM gloops: well you dont have to abandon the old one, keep it running until you get the new one set up
05:47 AM XXCoder: indeed what I meant gloop :)
05:48 AM XXCoder: ping yeah linuxcnc isnt like marlin they change settings names seemly 10 times per version
05:48 AM XXCoder: your configuration HAL should work just fine
05:49 AM pingufan: I need to use (again) a miniITX board (because of limited space). So I have (again) OnBoard graphics. But I can switch to AMD A10 (64 Bit board with ATi graphics). Drawback: No OnBoard parallel port any more!
05:49 AM pingufan: Will this work?
05:50 AM XXCoder: only one connector on board right? one PCI
05:50 AM Loetmichel: should, if you can get a good pcie lpt card
05:50 AM pingufan: Yes.
05:50 AM pingufan: Well, the new board would have one PCIe
05:50 AM Loetmichel: you could also simply get an old PCI graphics card and go that route
05:50 AM Loetmichel: one that is still supported
05:51 AM XXCoder: nearly all motherboards has inbuilt parallel anyway
05:51 AM Loetmichel: mach64 comes to mind
05:52 AM pingufan: MiniITX only has one socket. Newer boards have PCIe, oder ones have PCI. But newer have no parallel port, so this socket us used up by a PCIe parallel card.
05:52 AM pingufan: Nothing free for a plugin card.
05:52 AM pingufan: (for graphics)
05:52 AM XXCoder: why cant have larger board
05:53 AM pingufan: Because of limitations in room/space. It is built into the CNC mill.
05:53 AM Loetmichel: pingufan: didnt you say you have one free PCI?
05:54 AM Loetmichel: XXCoder: i know that problem... once built a CNC for a coworker...
05:54 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=13131
05:54 AM pingufan: On old board, yes. This is a 1-core, 1500MHz VIA C7 CPU with 2 GB RAM and a small CF card as "SSD"
05:55 AM XXCoder: heh can you cut board in half and solder wires? :)
05:55 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=13149 <- nearly had to use a hammer to get that CPU card in there ;)
05:55 AM XXCoder: 90 degree bend bmotherboard
05:55 AM pingufan: Sure, I can. But I am afraid it will not work afterwards. :D
05:55 AM XXCoder: lol bet it'd be hard, expecially if theres layers
05:56 AM pingufan: No. I want to stay with OnBoard graphics.
05:56 AM XXCoder: is there any boards with inbuilt gamer gpu?
05:56 AM XXCoder: closer to gaming type
05:57 AM pingufan: Don't know. AMD A10 is primarily for Desktop purposes. But it is relatively powerful.
05:57 AM pingufan: It is a soldered-on All-in-one CPU+GPU
05:58 AM Loetmichel: pingufan: i reccomend these: https://www.ebay.de/itm/INTEL-DESKTOP-BOARD-DH61DL-G14066-206-MINI-ITX-Sockel-1155-M13393/273350036117
05:58 AM Loetmichel: work seriously well with LinuxCNC
05:58 AM pingufan: You can compare it with an Atom, but it is more powerful.
05:58 AM Loetmichel: tested it a few times
05:58 AM XXCoder: I wonder if something like raspiberry is more powerful than your board now? lol
05:59 AM XXCoder: too bad Nextthing company went under.
05:59 AM pingufan: My livingroom PC uses an VIA C7 CPU, a fully blown-up openSUSE+KDE, and smoothly(!) plays FullHD movies with 10% CPU load.
06:00 AM Loetmichel: pingufan: NOT the one from the link though... it has bent CPU pins
06:00 AM Loetmichel: but that *61 chipset is fine for LinuxCNC
06:01 AM pingufan: Currently I have some BIOSTAR A68N-5600 boards in stock.
06:02 AM Loetmichel: never tried an AMD board for linuxCNC
06:02 AM Loetmichel: could work
06:02 AM Loetmichel: but you would need a PCIe-lpt port card
06:03 AM Loetmichel: and one that works on LinuxCNC, too (not all do)
06:03 AM pingufan: I never will touch an Intel in my life any more.
06:04 AM pingufan: Lot of money for nothing.
06:04 AM Loetmichel: if you say so.. your decision. makes it hard to help you when something goes wrong though
06:04 AM pingufan: Is this now used debian also such stripped down one, or is it meanwhile as feature-rich as openSuSE ?
06:05 AM jthornton: geez putube videos suck, I've looked at 25 videos on wood turning and they all start out with a bunch of irrelevant crap
06:05 AM pingufan: I assume there is (again) an ISO available?
06:06 AM pingufan: Unpack to a small hdd/ssd and done?
06:08 AM pingufan: Really, I have best experiences with AMD CPUs. I use them since AMD 486 times. And I build very strong servers, too. All with AMD.
06:08 AM pingufan: Doing the same with Intel would cost lots more.
06:08 AM pingufan: And at least openSUSE has no issues on AMD based systems. :)
06:09 AM Loetmichel: pingufan: as i said: your decision. just be aware that not that many here use AMD systems for LinuxCNC, so it may be a problem getting quastions answered
06:10 AM Loetmichel: just download the most recent live Cd, put it in your other PC and test it...
06:10 AM pingufan: Is thewre an IMAGE available, or do I have to install Debian and then linuxCNC ?
06:10 AM Loetmichel: its not bad IMHO (the debian)
06:11 AM XXCoder: sriracha cashews
06:11 AM Loetmichel: http://www.linuxcnc.org/linuxcnc-2.7-wheezy.iso
06:11 AM pingufan: And then I can install from live CD -> HDD ?
06:11 AM Loetmichel: XXCoder: you like hot nuts?
06:11 AM Loetmichel: :-)
06:11 AM Loetmichel: yes
06:11 AM XXCoder: yep yep lol
06:12 AM pingufan: Is it 64 bit or 32 bit?
06:13 AM pingufan: Does it have GNOME or KDE ? (I prefer KDE)
06:13 AM Loetmichel: no idea, i would assume 64 bit because 32 bit CPUS are gone since core duo
06:13 AM miss0r: 'afternoon
06:14 AM pingufan: What desktop does it run? Gnome, KDE, ...
06:15 AM pingufan: BTW: Can I use any Linux with Realtime Kernel? I.e. also openSUSE Leap 15.0 ?
06:15 AM pingufan: Of course only of interest when installing linuxcnc is very simple.
06:17 AM pingufan: I will think about that in general. Have a nice weekend. Have to leave now.
06:17 AM XXCoder: them hot nuts is yummy
06:17 AM miss0r: XXCoder: Are we going into the random statement buisness?
06:17 AM XXCoder: miss0r: it wasnt random lol
06:18 AM miss0r: who is talking hot nuts? :S
06:18 AM XXCoder: read up :)
06:18 AM miss0r: meh... cant be bothered :D
06:19 AM XXCoder: I understand, 100lb keyboard buttons and 200lb mouse is annoying to use ;)
06:19 AM miss0r: yeah... I take the mechanical keyboard trend very serious :D
06:21 AM XXCoder: :)
06:22 AM gloops: hmm, decision is whether to mount existing bandsaw frame with considerable weight on gantry, or strip wheels and adjusters and mount them on much lighter beam
06:22 AM gloops: time and weight thing
06:22 AM miss0r: trying to safe my strength for later.. Taking the misses to a serious steak house later :D
06:24 AM gloops: i only want to do it once so ill start stripping...
06:26 AM Loetmichel: miss0r: not the worst idea... should take my wife to a restaurant, too. Last time i did that must have been a decade ago or so...
06:26 AM XXCoder: loet poor wife of yours havent eaten whole time?? lol
06:26 AM miss0r: Loetmichel: Hehe. We don't get to do that very often either. Well, she insisted on going to the theater, so I said we'd need some steak first :)
06:26 AM miss0r: lol
06:27 AM Loetmichel: XXCoder: she is a good cook... so no, we did eat a bit TOO well... judging by our combined weight ;)
06:27 AM XXCoder: :)
06:28 AM miss0r: We are somewhat set back by having a 3year old kid :) doing stuff like that needs a baby sitter.
06:29 AM miss0r: but as we will get our second kid this december, we figured it would be now or much later :)
06:30 AM Loetmichel: hihi
06:30 AM XXCoder: lol
06:31 AM XXCoder: i dont plan to have kids ever
06:31 AM XXCoder: im bit old to have kids anyway, at 42. sure my dad was nearly 50 when I was born but whatever
06:31 AM Loetmichel: "life starts when the kids are out of the house" ;)
06:32 AM XXCoder: mine havent started anyway so whatever lol
06:32 AM miss0r: Loetmichel: I hear'ya :D
06:32 AM Loetmichel: <- have the "luck" that my wife is overweight so a pregnancy is "not recommended" by the doc.
06:33 AM miss0r: Loetmichel: Just remember to sleep on your belly
06:33 AM Loetmichel: als by now we are both a bid old... she being 53 and me being 49
06:33 AM miss0r: if she is not strong enough to turn you over, you are home safe ;)
06:34 AM Loetmichel: miss0r: belley?
06:34 AM miss0r: stomach
06:34 AM Loetmichel: i dont get it, sorry
06:34 AM Loetmichel: you mean because no sex?
06:34 AM miss0r: if you sleep face down, and your wife cannot turn you over, you should not worrie about having kids... Its a joke :)
06:35 AM Loetmichel: THATs the part we have fun with... the pregnancy part is the one that would be dangerous for her
06:36 AM miss0r: yeah :) don't forget the fun ;)
06:36 AM XXCoder: I thought being overweight would help pregancy but guess not?
06:37 AM miss0r: To a certain point I suppose. I know it can be hard for the unhealthily skinny ones
06:59 AM XXCoder: this is insane https://www.youtube.com/watch?v=wVphFkaX1gg
06:59 AM XXCoder: c64 outside for years.
07:40 AM Loetmichel: XXCoder: no, thats pretty normal. old electronics is surprisingly robust
07:42 AM * Loetmichel had a ZX81 mainboard with a new rom in the side cover of a house furnace for about 15 years... with occasional water (leaking pipes), heat up to 80°C and frost in the winter when the furnace didnt start for a few days
07:42 AM Loetmichel: worked flawlessly until the furnace died for good
08:32 AM Rab: Loetmichel, can you give a few details about your remote LinuxCNC setup? Are you using VNC?
08:33 AM Rab: And in the video I see VLC monitoring the camera. Is that an IP camera on the machine, or something else?
09:10 AM Loetmichel: Rab: i am using VNC, yes
09:10 AM Loetmichel: but on the lates build
09:10 AM Loetmichel: its an USB endoscope camera
09:11 AM Loetmichel: you can see it in the second part of the video as a black cylinder sticking into the vacuum foot on the mill spindle
09:11 AM Loetmichel: and i used VLC to encode it as a stream
09:11 AM Loetmichel: MJpeg IIRC
09:11 AM Loetmichel: because of lag
09:12 AM Rab: Loetmichel, thanks! Is the USB camera running on the LinuxCNC computer?
09:16 AM skunkworks: holy - shit..
09:22 AM Rab: Loetmichel, cool! I was considering the same thing but it seemed like USB cam would introduce a lot of overhead.
09:24 AM gregcnc: skunkworks what's going on there? remote access to winduhs
09:26 AM skunkworks: a virtual machine getting passed the nvidia dedicated video on this laptop.
09:26 AM Loetmichel: skunkworks: sounds like a plan if it can play Elite Dangerous ;)
09:27 AM skunkworks: so windows is running the real nvidia hardware - so the (for me) fusion doesn't complain about crappy graphics
09:27 AM skunkworks: yes - people use this for gaming...
09:27 AM Loetmichel: <- wants to switch from windows on his home machines to Linux for a while now... cant because of Games though
09:28 AM skunkworks: this would solve that ;)
09:28 AM skunkworks: I have been chasing this unicorn for a little while.
09:38 AM skunkworks: now see if I can get it to work on debian...
09:57 AM FinboySlick: skunkworks: I didn't expect laptops with dual graphics to have an IOMMU but that makes sense.
09:58 AM skunkworks: FinboySlick: yes - it is a 4th gen i7
09:58 AM skunkworks: Now - if it will run linuxcnc over ethernet... I might have the golden goose
09:58 AM FinboySlick: skunkworks: This is likely to only work with an external monitor though.
09:59 AM skunkworks: No - the image is remoting into the vm with nothing attachced
10:00 AM FinboySlick: skunkworks: Hmm... So RDP to a vm that has the GPU passed through hardware?
10:00 AM skunkworks: I have not tried to see if I can connect an external monitor to display the nvidia card.. that would be nice
10:00 AM skunkworks: FinboySlick: yes
10:01 AM FinboySlick: skunkworks: It's a typical setup. the intel card is connected to the built-in monitor and the external display port/hdmi is connected to the dedicated graphics.
10:01 AM skunkworks: it is pretty amazing - I was spinning around a pretty complicate fusion 360 model
10:01 AM skunkworks: FinboySlick: sure - but sometimes laptops have odd switching electronics..
10:02 AM FinboySlick: skunkworks: Yeah. I fumbled around with optimus a bit on my T520
10:02 AM skunkworks: on a normal pc hardware - yes - you would have a dedicated hot video card you pass through to the vm that has its own video ports
10:02 AM skunkworks: it might work on this laptop - just not what I was really needing
10:03 AM skunkworks: I wanted a laptop that I could run windows/cad through a vm
10:04 AM FinboySlick: With the advances in 3D graphics, most CAD packages are way overdue for a rewrite. It'd be nice if they actually did portable code for once.
11:04 AM fragalot: Hey-o
11:04 AM fragalot: miss0r: picking up that drill press tomorrow
12:26 PM JesusAlos: Hi
12:30 PM gloops: evening
12:41 PM Tom_L: afternoon
01:26 PM gloops: this is the end for the car https://twitter.com/SkyNews/status/1048198620376260608
01:41 PM skunkworks: wow - this laptop might be my perfect computer.
01:42 PM skunkworks: it seems to run realtime (rt_preemt) and the ethernet seesm to play well.
01:42 PM skunkworks: sof ar
01:42 PM skunkworks: so far
01:42 PM skunkworks: Now I need to get the vm working on debian (I got it working on ubuntu(
01:44 PM CaptHindsight: AMD laptop? :)
01:44 PM CaptHindsight: skunkworks: which NIC does it use?
01:48 PM skunkworks: CaptHindsight: no - msi intel
01:48 PM skunkworks: it uses a qualcomm... First time I have run into them
01:48 PM skunkworks: so odd stuff ;)
02:27 PM andypugh: Anyone here speak Russian?
02:28 PM andypugh: I have exactly the same problem with my welder as this guy: http://websvarka.ru/talk/topic/11069-skhema-inv200acdc-plata-regulirovki/
02:29 PM andypugh: And Google Translate is vaguely hep=lpful, except in telling me whether the chip swap he did actually worked.
02:34 PM CaptHindsight: andypugh: I have a similar/same one (different color and name on enclosure)
02:34 PM CaptHindsight: mine works if you want to try and debug
02:34 PM andypugh: Yes, mine is actually Green and branded “Rehman”
02:35 PM CaptHindsight: yellow and wsme200
02:35 PM andypugh: I am at the same point as the guy on the forum post, and I am also thinking about just replacing the switcher chip.
02:36 PM andypugh: But it is probably easier just to graft in a little eBay buck converter,,,,
02:36 PM CaptHindsight: https://www.ebay.com/itm/200A-Commercial-Quality-AC-DC-Tig-Stick-Welder-from-The-Welder-Repair-Guy/253080015959
02:37 PM andypugh: The board must be pretty old-xhool to have that many components/
02:37 PM CaptHindsight: new boards were all over ebay
02:37 PM andypugh: It is full of anlogue switches, shift registers, op-amps…
02:39 PM CaptHindsight: https://www.ebay.com/sch/i.html?_from=R40&_sacat=0&_nkw=wsme200&LH_PrefLoc=1&_sop=16
02:39 PM andypugh: I would prefer to fix this one.
02:40 PM andypugh: I have weleded with it by using a lab PSU into the potetiometer inputs....
02:40 PM CaptHindsight: maybe we have different boards
02:41 PM andypugh: I have _exactly_ that board from the posts.
02:41 PM andypugh: (In fact I found that with a Google images search)
02:45 PM CaptHindsight: whats easier for you, swap the switcher or?
02:47 PM andypugh: Well, it broke once already....
03:57 PM andypugh: Interesting bit of mech design today
03:58 PM andypugh: When I am hobbing gears I need to swing my milling table by a small amount, with some accuracy.
03:59 PM andypugh: I decided it would be nice to set up a micrometer head for the job, and arrange it so that 1mm = 1 degree.
04:00 PM andypugh: You can see the swinging arrangement here: https://photos.app.goo.gl/adMDJXHmSan8MRm3A
04:01 PM andypugh: 57.296 mm from the pivot gives that scalong for small angles.
04:01 PM gregcnc: looks like Y servo?
04:02 PM andypugh: Yeah, you need to look above there, where the swinging X bolts on to the Y carriage.
04:02 PM andypugh: (The adjuster isn’t there yet)
04:02 PM gregcnc: no wonder i can't see it
04:02 PM andypugh: At larger angles the small-angle approximation is no longer true, so some sort of “thing” is needed to correct it.
04:03 PM andypugh: I couldn’t figure out what the shape needed to be, so I just drew lots of angles in CAD as the micrometer swung away, and joined the dots.
04:06 PM XXCoder: lol guy orders $10 fan and gets $100 cooling system. that does not fit. is it a win or loss? https://twitter.com/jefmajor/status/1047666730951004160
04:06 PM andypugh: https://photos.app.goo.gl/bgoPXVp2hfnmHieP6
04:07 PM andypugh: It looked too simple, so I modelled the whole thing and checked it out as a CAD assembly with constraints.Wrorks perfectly.
04:07 PM gregcnc: ah, so the contact point is corrected
04:08 PM andypugh: https://photos.app.goo.gl/6CVNzxT3mAMtPiBb7
04:08 PM andypugh: I really don’t know if I would evet have managed to work out that shape with maths.
04:09 PM andypugh: (And the actual shape varies with how far back from the surface the pivot point is, so I need to measure that accurately.
04:12 PM gregcnc: I'd probably use the same method. It is geometry, but defining the curve isn't isn't easy.
04:13 PM andypugh: It took me a few goes. it was only when I changed mental coordinate systems and strated to move the micrometer head rather than the table that it came together in my head.
04:19 PM gregcnc: you use a horizontal mill for gears now and this is why the table is angled?
04:20 PM andypugh: Yes
04:20 PM gregcnc: It's also possible to program the equivalent with some Y feed?
04:20 PM andypugh: https://www.youtube.com/watch?v=PFTHY5U8v-U
04:21 PM andypugh: Yes, but with Y-feed you also need to angle the 4th axis and the work on the table.
04:23 PM Deejay: gn8
04:23 PM diverdude is now known as Guest17331
04:24 PM gregcnc: oh, the cutter must be angled to the gear axis
04:25 PM andypugh: Yes, to allow for the helix angle of the hob
04:25 PM diverdude: Hi, anybody knows what the expected behaviour of accelstepper is if i ask my motor to move to X, call run() continuously - and before it has reached its end destination i ask it to move to Y and keep calling run() continuously?
04:29 PM andypugh: Calling run() how and where and what?
04:29 PM diverdude: andypugh: in loop()
04:29 PM andypugh: (To be honest as I don’t understand the question I might not have an answer)
04:30 PM andypugh: Let us start at the beginning. What do you mean by “accelstepper” ?
04:31 PM andypugh: (are you possibly talking about robot gerbils? …. I mean GRBL?
04:33 PM XXCoder: https://imgur.com/gallery/rr7gibZ pretty cool
04:33 PM * jthornton gives up trying to make a bootable usb with rufus
04:33 PM diverdude: andypugh: i am talking about the library accelstepper for arduino
04:34 PM andypugh: XXCoder: One of these, I assume: https://www.youtube.com/watch?v=w4kPDhrhlgk
04:35 PM XXCoder: interesting. I kinda wondered
04:35 PM andypugh: Brilliant machines, if you don’t need to make money
04:36 PM andypugh: diverdude: Ah, well, you are vaguely in the wrong place, this is LinuxCNC.
04:36 PM andypugh: But I would _expect_ it to be OK to continually move the end-point
04:37 PM andypugh: XXCoder: Those side-uprights on that planer are immense!
04:37 PM CaptHindsight: for some cuts shaving is quicker
04:37 PM XXCoder: too expensive a machine for parts it makes?
04:37 PM CaptHindsight: lots of machine to have around just in case
04:38 PM CaptHindsight: what application would be a full time job for a shaver vs mill?
04:38 PM andypugh: XXCoder: It’s a funny quote, possibly from “This Old Tony”, possibly from someone else “You can make anything with a Shaper except a profit”
04:38 PM CaptHindsight: linear bearing roughing?
04:38 PM XXCoder: LOL thats funny
04:38 PM andypugh: And that is even more true of a planer.
04:39 PM andypugh: A huge plaber is _the_ tool to sort out a lathe bed.
04:39 PM CaptHindsight: rails of some sort
04:39 PM CaptHindsight: elevator tracks
04:41 PM diverdude: andypugh: what if forexample i give the motor (via accelstepper) a new destination in opposite direction of what it is currently moving in would it change direction immedietly? would it slow down, halt and go back...will it complete its move and then go back...difficult to say
04:42 PM andypugh: I think it would slow (within accel limits) to a stop, then accelerate in the other direction.
04:42 PM andypugh: (This is certainly what the LinuxCNC step-generator would do)
04:44 PM diverdude: andypugh: ok thats interesting
04:44 PM andypugh: Of course, the easy way to find out is to experiment.
04:45 PM diverdude: so linuxcnc would not finish its current move - it would as fast as possible start working on the new task
04:45 PM diverdude: agreed...i am just not connected to my machine here :(
04:46 PM andypugh: The _step_generator_ would if you changed the commanded endpoint.
04:47 PM andypugh: That’s not what the trajectory planner would do, or every G-code file would become a straight move from beginning to end…
05:46 PM jthornton: hmm I've installed dual boot but didn't see an option to boot to windblows...
05:53 PM XXCoder: LOL https://imgur.com/a/sDFPhiM
05:57 PM infornography: merry weekend
05:58 PM infornography: hohoho
05:59 PM jthornton: hey from Murray Ky
06:00 PM infornography: hey
06:01 PM XXCoder: hey
06:04 PM * jthornton heads to dinner
07:12 PM skunkworks: https://youtu.be/WZ60jBCT94w
07:14 PM Tom_L: but why?
07:16 PM skunkworks: ;)... mainly because want a laptop that i can run windows and also linuxcnc
07:16 PM CaptHindsight: just wait until we have the plots in high res with shading
07:18 PM CaptHindsight: QEMU sure has come a long way since the 90's
07:21 PM XXCoder: lotremember ping guy with pc issues? wonder if this would work https://www.amazon.com/Jetway-NP591D4-3150-Braswell-Celeron-Pico-ITX/dp/B01BZ1XIIS/ref=sr_1_2?ie=UTF8&qid=1538785031&sr=8-2&keywords=Pico-ITX
07:21 PM XXCoder: what a tiny pc
07:24 PM CaptHindsight: always pricey since they are made in low volume
07:25 PM CaptHindsight: back in the late 90's there were some STPC boards that size for ~$50
07:32 PM robotustra: evening
07:32 PM Tom_L: andypugh i bet robotustra could help
07:33 PM Tom_L: robotustra you speak russian right?
07:33 PM XXCoder: CaptHindsight: ya guy had issue, he cant use larger boards than mini ones which have only one pci slot
07:33 PM robotustra: yes
07:33 PM andypugh: With the robot gerbils?
07:33 PM andypugh: Ah, with that :-)
07:33 PM Tom_L: yeah
07:34 PM Tom_L: unless you got it already
07:35 PM andypugh: I proved that a small DC-DC converter (£1.86) was a solution, and I can jusy ignore the not-working bits of the original circuit
07:35 PM CaptHindsight: XXCoder: was that what the AMD discussion was about earlier?
07:36 PM XXCoder: ping wanted vnc to work on his old pc which only runs ubuntu 8
07:36 PM andypugh: XXCoder: I was spammed by Mini-ITX today, they have the last 200 D2550HN coming in. (fanless dual-core Atom, Mini-ITX, 1 x PCI + Parport
07:36 PM XXCoder: we suggested him to upgrade
07:37 PM andypugh: https://www.mini-itx.com/store/~D2550HN
07:37 PM XXCoder: inbuilt video card and parallel I see
07:37 PM robotustra: I finally managed to add opengl widget into my gui https://imgur.com/srombUk
07:38 PM andypugh: Yes. The email seemed to hint that they knew they had dedicated users for niche applications.
07:38 PM XXCoder: that guy might want this one
07:38 PM infoproxy: I can't buy?
07:38 PM XXCoder: dont see any price for it tho
07:39 PM infoproxy: *click click click * take my money
07:39 PM Tom_L: ... long lead time
07:39 PM andypugh: infoproxy: “Please register your interest by replying to this email or clicking through the link below.
07:39 PM andypugh: “ firstname.lastname@example.org
07:40 PM andypugh: “Calling all our long-term D2550HN project customers!
07:40 PM andypugh: We have secured a final batch of D2550HN motherboards. It is extremely unlikely we will be able to source more units after this purchase as the processor used is discontinued. This is your opportunity to purchase.
07:40 PM andypugh: The small print: Customer orders to be made in units of 5. Priority will be given to customers on a first come, first served basis. Limited to 200 units total. Estimated delivery date: Mid November.”
07:40 PM infoproxy: *hands his money to andypugh*
07:40 PM XXCoder: doubt want buy 5 of em lol
07:40 PM robotustra: what is D2550HN motherboard?
07:41 PM andypugh: It’s just a Mini-ITX with parport and PCI.
07:41 PM andypugh: It’s not high on my list, I prefer the ones with a 12V power jack
07:41 PM robotustra: old ones?
07:41 PM Tom_L: you would need to run RTAI on it wouldn't you?
07:41 PM andypugh: I would expect so.
07:42 PM Tom_L: their pico psu is rock solid though
07:42 PM Tom_L: then you've got your 12v
07:43 PM andypugh: Mini-ITX have a nice board finder. You can specify (for example) 12V power and full-size PCI. https://www.mini-itx.com/store/category?type=motherboard&maxram=4GB-or-more&lan-ports=over-1&storage-ports=over-1&sortby=price&page=1
07:43 PM andypugh: (Though that combionation bives zero hits)
07:44 PM andypugh: Parport + 12V gives you https://www.mini-itx.com/~JNF9U-2930
07:44 PM Tom_L: https://www.mini-itx.com/~JNF9U-2930
07:44 PM Tom_L: i'd go that route on one personally

07:45 PM robotustra: cool boards
07:45 PM robotustra: what cpu is there?
07:45 PM robotustra: 486?
07:46 PM robotustra: whaaaaaaat
07:46 PM robotustra: quad core?
07:46 PM robotustra: celeron...... :\
07:47 PM Tom_L: was the cedar trail one step up from the bay trail?
07:49 PM Tom_L: bay trail was 4 core too
07:49 PM Tom_L: 2Ghz
07:50 PM XXCoder: 8086 2 ghz ;)
07:50 PM Tom_L: with dos would be awesome
07:50 PM robotustra: dos is not muticore OS
07:50 PM Tom_L: i know
07:51 PM Tom_L: but it doesn't need them
07:51 PM robotustra: not even protected mode
07:51 PM andypugh: Night all
07:51 PM Tom_L: later andy
07:51 PM robotustra: england went to bed
07:52 PM robotustra: quebec will go soon
07:52 PM robotustra: what's new about fancy gui which was made in blender?
07:53 PM robotustra: for linuxcnc 2.8?
07:54 PM infoproxy: I run DOS in 3D VR
07:55 PM infoproxy: It feels like you could reach out and touch the text
07:56 PM robotustra: Tom_L, do you follow that gui?

08:09 PM CaptHindsight: I'm not really crazy about the feeling of wax on my legs
08:09 PM XXCoder: long john
08:10 PM CaptHindsight: too many layers
08:10 PM XXCoder: layers all way down
08:10 PM CaptHindsight: I start to feel like a strudel
08:11 PM CaptHindsight: I use Thompson water seal on outwear
08:11 PM CaptHindsight: and/or PTFE spray
08:22 PM CaptHindsight: just check the SDS, Thompson just uses mineral spirits as a vehicle for paraffins
