[03:49:23] <XXCoder> so silent...
[03:49:35] <XXCoder> literally all irc channels in in said nothing for while
[03:49:40] <XXCoder> *i'm
[03:50:03] <MarcelineVQ> Change the channel marge :>
[03:50:16] <XXCoder> lol
[03:50:39] <XXCoder> its bit strange really as it includes one channel that usually talks a lot

[04:21:49] <gloops> irc is dying
[04:22:21] <gloops> people communicate with gifs these days
[04:22:25] <MarcelineVQ> I've been hearing that for 15 years
[04:23:25] <gloops> well the facebook cnc grouos have 10000 members - tell them to come here, none do
[04:25:04] <gloops> bridge of my nose is throbbing 3 days after i clouted it
[05:20:04] <Deejay> facebook is dying. irc will live forever!
[05:23:54] <XXCoder> theres xkcd of that too lol
[05:24:05] <XXCoder> not facebook but irc being forever
[05:24:41] <MarcelineVQ> XXCoder: competing standards?
[05:24:59] <XXCoder> nah
[05:25:11] <XXCoder> just google xkcd irc if youre curious lol

[05:34:52] <jthornton> morning
[05:36:04] <XXCoder> hey jthornton
[05:37:05] <jthornton> we lost power for a while last night
[05:37:58] <XXCoder> ouch heh
[05:38:12] -!- huibuuh has joined #linuxcnc
[05:39:01] <jthornton> just in the middle of installing my new distribution panel so the electric service area is a mess and I didn't feel like messing with it in the dark so it was oil lanterns
[05:44:41] <XXCoder> you was working on power system when power went out? wouldnt that not affect uou because you already turned it off?
[05:47:07] <jthornton> no a transformer blew up and the whole neighborhood was out
[05:54:04] <XXCoder> oh not talking about why it happened, wouldnt you not affected because you';d have already turned power off to modify it?
[05:54:41] <jthornton> no, I was watching TV when the transformer blew up
[05:54:47] <XXCoder> ahh ok lol
[05:58:16] <jthornton> one of my cameras gets a new random ip after a power outage and now I forgot the magic needed to change it in motioneye
[05:59:34] <jthornton> and the author thinks that answering questions on github is good enough for documents lol
[05:59:42] <XXCoder> you can reserve ip to mac address
[05:59:59] <XXCoder> most routers has this
[06:00:17] <XXCoder> so its still "dynimatic" but same mac address gets same ip if reserved
[06:00:29] <jthornton> I tried to set it in the camera as static but didn't work to good
[06:00:50] <XXCoder> some stuff dont work with static yeah thats why reservations is great thing to have
[06:00:59] <jthornton> I'll have to see what I can do with the router... it's behind at least 2 switches
[06:01:55] <XXCoder> once you reserve it, restart your camera it'll grab the correct ip
[06:02:29] -!- ferdna has joined #linuxcnc
[06:04:07] <jthornton> https://imagebin.ca
[06:04:12] <jthornton> from this page?
[06:05:24] <jthornton> hmm my test raspberry pi is on 50...
[06:07:04] <XXCoder> yep
[06:07:15] <XXCoder> dhcp reservation
[06:07:24] <XXCoder> put in ip address and mac address
[06:07:40] <XXCoder> copy the hostname if it exists
[06:07:52] <XXCoder> dont forget to click enable then save
[06:08:25] <jthornton> bbib gotta setup the coop2 raspberry pi static ip
[06:08:40] <jthornton> need this monitor as only one with HDMI plug
[06:09:03] <XXCoder> cool
[06:10:45] <jthornton> pi

[06:22:42] <XXCoder> oh FINALLY find a way to actually run a vismach
[06:22:48] <XXCoder> http://wiki.linuxcnc.org
[06:22:55] <XXCoder> im running 5axis machine now
[06:27:25] <jthornton> cool
[06:28:18] <jthornton> does that page have more information than the documents?
[06:29:39] <XXCoder> somewhat
[06:29:47] <XXCoder> it actually says how to run machine for one
[06:30:09] <XXCoder> and location of exampkles! its in /usr/bin/5axiscnc for example
[06:30:29] <XXCoder> it doesnt say how to connect linuxcnc to virtual machine though
[06:30:56] <jthornton> I'll have to compare the two when I get done with all this ip mess
[06:31:16] <XXCoder> links at bottom is borked
[06:31:23] <XXCoder> links to videobin which dont exist
[06:31:37] <jthornton> I have the ip reserved for the camera so I just need to power cycle it?
[06:31:42] <XXCoder> yeah
[06:33:25] <XXCoder> capture() is still unknown
[06:33:49] <XXCoder> your version is better formatted honesly but other one has some missing details
[06:33:52] <XXCoder> but not a lot
[06:35:43] <XXCoder> wow! scaragui is fairly good commented and has links to certain C codes for more details
[06:35:57] <XXCoder> example # parameters that define the geometry see scarakins.c for definitions these
[06:35:57] <XXCoder> # numbers match the defaults there, and will need to be changed or specified on
[06:35:57] <XXCoder> # the commandline if you are not using the defaults.
[06:36:19] <jthornton> hmm camera is still on 52
[06:36:42] <jthornton> and reserve disappeared from the reservations list
[06:36:46] <XXCoder> have you released it? realized its still set
[06:36:59] <XXCoder> oh odd did you save it, and save setting page also?
[06:37:03] <jthornton> released it? what is that?
[06:37:08] <XXCoder> some router gui is weird
[06:37:22] <XXCoder> oh devices list there is "release" it expires ip address right away
[06:38:13] <jthornton> mine has a revoke and reserve button next to each client
[06:38:22] <XXCoder> oh revoke is basically same
[06:38:55] <jthornton> ok it's gone from the DHCP list
[06:40:43] <jthornton> poor chickens are going wtf is all that noise out there can't they tell it's sleepy time
[06:41:02] <XXCoder> does page itself has "save settings" seperate from save dhcp reservation?
[06:41:24] <XXCoder> if so, you have to click it after you save dhcp reservation. sometimes routers really has wtf design
[06:41:28] <jthornton> cool, it worked!
[06:41:37] <XXCoder> awesome :)
[06:41:55] <jthornton> thanks, now on to the next problem to solve this morning
[06:41:58] <XXCoder> it'll be always that ip now
[06:42:21] <XXCoder> btw that vismach file is quite detailed, but does NOT say what capture() is lol
[06:43:21] <XXCoder> reaxing max5gui now
[06:43:27] <jthornton> the scaragui one?
[06:43:32] <XXCoder> yeah
[06:43:42] <XXCoder> that one is arm type machine
[06:43:52] <XXCoder> so it has quite complex math and connections
[06:45:04] <XXCoder> capture() not defined ahain. I am starting to wonder if its taken from linuxcnc
[06:45:18] <jthornton> yikes it's 34°F outside and I didn't pick up the garden hoses
[06:45:35] <XXCoder> man your region have faster and wider range of temeprate
[06:45:41] <XXCoder> here its styill steady 50f
[06:45:43] <XXCoder> +
[06:46:02] <jthornton> 34-55 today
[06:46:16] <XXCoder> capture() is always called in this line: work = capture()
[06:46:33] <XXCoder> then its put into collection with other parts
[06:47:21] <jthornton> we need to see if hazzy can shed some light on this
[06:48:28] <jthornton> trying to roll all 4 tests into 1 for the chicken door/light astral thingy
[06:48:39] <XXCoder> nice
[06:49:16] <XXCoder> hmm max5gui is 5 axis mill, head rotates B axis, table have rotate, C axis

[06:49:56] -!- fragalot has joined #linuxcnc
[06:50:47] <XXCoder> when I close linuxcnc, it also closes sim machine
[06:50:55] <gloops> hmm something funny here, not used machine for a couple of weeks, start up - homing wrong direction
[06:51:00] <XXCoder> but it dont run with linuxcnc
[06:51:12] <XXCoder> gloops: you sure you loaded right hal?
[06:51:16] <jthornton> gloops: stepper?
[06:51:38] <gloops> 2 steppers on that axis
[06:51:47] <gloops> XXCoder pretty sure yeah lol
[06:51:57] <jthornton> direction wire broken?
[06:52:18] <XXCoder> can you move it other way? if not probably as jt said
[06:52:26] <gloops> well both steppers are going wrong way, seems like a config issue more than anything
[06:52:54] <gloops> i cant jog it until its home, actually ill check switches might be stuck or something
[06:53:35] <jthornton> ah yea limit/home switches could be the issue
[06:55:09] <XXCoder> hbmgui looks like small mill machine. plain 3 axis horzional mill
[06:57:55] <XXCoder> ah! The .hal file of your machine in your /home/user/linuxcnc/config/yourmachine loads this script with "loadusr" al a HAL component and connects the axis. Following important things are described in the script:
[06:58:10] <XXCoder> so it must be called from HAL in order to work
[07:00:12] <jthornton> making progress? keeping notes?
[07:00:23] -!- ferdna has quit [Quit: Leaving]
[07:00:27] <XXCoder> nothing that that page doesnt say so far
[07:00:40] <XXCoder> you can load machine directly but it doesnt function, just displays machine
[07:00:56] <XXCoder> you just need to add loadusr (machine define file)
[07:01:00] <XXCoder> in HAL
[07:01:30] <gloops> false alar,. 12v supply to home switches hadnt started up, working ok now
[07:01:33] <gloops> alarm
[07:01:40] <XXCoder> ah lol
[07:01:52] <XXCoder> its trying to get off switch if its normally off
[07:01:58] <XXCoder> *on
[07:02:11] <XXCoder> so its going backwards trying to get off switcgh
[07:02:16] <gloops> yeah that would be it
[07:02:48] <gloops> glad i didnt start messing with the config homing took some messing to get right
[07:02:58] <XXCoder> jthornton: I might finally know what capture() does
[07:03:07] <XXCoder> # "tooltip" for backplot will be the tip of the finger
[07:03:07] <XXCoder> tooltip = Capture()
[07:03:21] <jthornton> cool
[07:03:50] <XXCoder> not quite sure what that means but maybe it gets model from linuxcnc, tool size so on and adds it there
[07:04:09] <jthornton> maybe reads the tool table?
[07:04:18] <XXCoder> yeah maybe
[07:04:47] <XXCoder> I suspect it gets diameter and length
[07:05:15] <XXCoder> pumagui seems to be good on notes
[07:05:32] <XXCoder> first one is very detailed but skips capture lol
[07:06:01] <jthornton> just need to collect all the bits into one txt file
[07:07:01] <XXCoder> what makes it bit unclear is this lines:
[07:07:08] <XXCoder> # tool or finger
[07:07:08] <XXCoder> finger1 = CylinderZ(0, 5, 50, 5)
[07:09:04] <XXCoder> that is in collection with few boxes then its collected with tooltip (the capture() variable)
[07:09:15] <XXCoder> maybe finger1 is "collet"?
[07:09:36] <XXCoder> I need to create HAL now
[07:10:45] <XXCoder> coniguring it to match hbmgui
[07:12:21] <XXCoder> it amazes me that theres no standard mill and no standard router
[07:12:26] <XXCoder> just weird machines
[07:13:08] <jthornton> yea a simple mill or lathe would be easier to follow
[07:13:28] <XXCoder> hbm is closest but its written strange way and its horzional
[07:13:36] <XXCoder> or maybe its too old and configation issue
[07:14:38] -!- P1ersson_ has quit [Ping timeout: 276 seconds]
[07:15:20] <XXCoder> thankfully scaragui while a arm, has clearly defined work area
[07:20:48] <XXCoder> hm it has 5 pins, so its bit more complex than I can make HAL file from
[07:21:09] <XXCoder> maybe ill just make your example machine and see later. its getting bit late so gonna sleep
[07:21:20] <jthornton> ok goodnight
[07:21:27] <jthornton> see you later
[07:22:53] <XXCoder> nice to make tiny progress there
[07:23:02] <XXCoder> I like your writing style way better
[07:23:05] <XXCoder> that pages a mess
[07:23:33] <jthornton> thanks :)
[07:23:49] <XXCoder> http://wiki.linuxcnc.org in case dont have link lol
[07:24:25] <XXCoder> maybe I can create a standard cnc mill and router and configurations for those and push it in
[07:24:29] <XXCoder> because dang
[07:26:43] <XXCoder> maybe need tp split it into 3 pages, overall and some details on existing files, then how to specify machine, then how to create HAL hat runs that virtual machine
[07:27:25] <XXCoder> in fact, it'd be perfect if last one has "start from nothing" example
[07:27:49] <XXCoder> create machine, then create hal to work with it, then finally making it work
[07:28:09] <XXCoder> anyway off to bed
[07:28:17] <jthornton> yep that's what we need a start from scratch super simple example that just works
[07:28:33] <jthornton> I've just eliminated one chicken door test :)
[07:32:47] <Tom_L> 41�F Hi 67
[07:33:31] <jthornton> yesterday they said low of 40°F but it's 33°F atm
[07:34:34] <Tom_L> hope you took notes setting up your camera IPs
[07:34:43] <jthornton> and I didn't pick up my garden hoses yesterday...
[07:48:04] <jthornton> I think I got that now, it's only one crappy camera that resists me setting a static ip lol

[16:52:39] <pcw_home> if you do a full screen, dense 3d contouring backplot, you lose...
[16:53:31] <pcw_home> other than that is like running LinuxCNC on a slower Atom (Say D525 or so)
[16:54:13] -!- russian_troll has joined #linuxcnc
[16:55:41] <JT-Shop> well that's not bad then, is the kernel RTAI or preempt?
[16:55:56] <pcw_home> Preempt-RT is what I'm running
[16:56:52] <JT-Shop> is there enough power to run an ethernet card?
[16:57:36] <pcw_home> I have not tried since the RPI Ethernet is interfaced via USB
[16:57:51] <JT-Shop> oh yea, I had forgot about that
[16:58:40] <pcw_home> the Odroid C2 Ethernet is known to work OK
[16:59:14] <pcw_home> so probably "Le Potato" would work also
[17:00:23] <pcw_home> rmu: I'd like to try the RealTimePi install but it looks like it needs a lot to get to a working graphic

[17:02:40] <pcw_home> I am running the RPI LinuxCNC with a SPI interfaced FPGA card (that connects to the RPI's GPIO connector)
[17:04:31] <JT-Shop> neat!
[17:09:57] <pcw_home> using hm2_rspi driver
[17:17:49] <rmu> I just made an experiment with official raspberry pi 4.14 rt preempt tree (built new kernel packages), but max jitter seems to be worse than with my older kernel
[17:18:12] <rmu> then i found out about RealtimePi, didn't try it or look at it yet

[17:27:26] <JT-Shop> time for me to snuggle with the chickens for some warmth as they are 106°F
[17:29:35] <rmu> pcw_home: what do mean with graphic install?

[17:30:06] <MarcelineVQ> JT-Shop: is it getting cold where you are already?
[17:30:23] <pcw_home> the RealTimePi install is a console only dist AFAICT
[17:30:43] <rmu> last nightly build is from 2018-09-17
[17:31:00] <rmu> pcw_home: apt install xubuntu-desktop and some time should take care of that
[17:32:20] <pcw_home> Yeah, still seems like I would need to have a free day for futzing about with dependencies

[17:34:50] <JT-Shop> MarcelineVQ: yea we had frost last night killed all the garden plants... burned some wood today
[17:35:50] <pcw_home> Maybe it just my unfamiliarity with the RPI, do thing like the hardware OpenGL driver get installed automatically?
[17:37:29] <rmu> didn't check native opengl yet
[17:37:49] <pcw_home> Gremlin is pretty painful without it
[17:38:32] <pcw_home> I guess I'm spoiled by I7s
[17:39:28] <rmu> you should try a 1992 vintage 68008 based controller ;)
[17:41:41] <pcw_home> Wasn't that a 8 bit bus version of the 68000?
[17:44:45] <rmu> yes
[17:45:30] <pcw_home> I'm curious to see how the RealTImePi kernel does. I need to have ISOLCPUs 1,2,3 to get long term reliability at a 1 KHZ servo thread and if if that could be avoided it would make the RPI more pleasant
[17:47:00] <pcw_home> I wonder if the person who wrote the hm2_rspi driver could be persuaded to port it to something a bit faster
[17:47:24] <rmu> like the lepotato?
[17:48:00] <rmu> i didn't manage to change kernel on that one
[17:48:33] <pcw_home> yeah at least you can have 4G of RAM but I think OpenGL support is a common issue with these ARM boards
[17:48:47] <rmu> they only do GLES AFAIK
[17:48:59] <pcw_home> sigh
[17:49:26] <rmu> that would need an ugly hack (like the one xscreensaver is using to make opengl screensavers run on GLES)
[17:50:40] <pcw_home> Yeah, I heard there was some kind of (possibly flakey) shim
[17:51:06] <rmu> so my glxgears are doing 150ish fps, i think that is not pure software rendering
[17:51:57] <pcw_home> I would not think so
[17:52:10] <XXCoder> run something that cannot be done in software render
[17:53:14] <rmu> the hardware opengl _should_ be synced to monitor refresh
[17:53:58] <pcw_home> I think that is the case AFAIKR

[17:55:50] <pcw_home> With software OpenGL when you started LinuxCNC there was about 5-10 second delay after axis painted the screen before the backplot was rendered
[17:56:20] <pcw_home> and backplot updates use about all of CPU when running

[20:36:42] <XXCoder> pink_vampire: I finally managed to run vismach virtual machine
[20:36:51] <XXCoder> its ... interesting. I gonna learn more about it
[20:37:37] <pink_vampire> what is "vismach"??
[20:38:14] <XXCoder> its set of scrips and programs to fake a machine
[20:38:17] <XXCoder> any kind of machine
[20:38:39] <XXCoder> examples come wiht fairly unusual horzional mill to machine arm

[20:47:06] <XXCoder> too bad that machine is not aviliable as example
[20:55:43] <pink_vampire> sorry I was next to the machine
[21:01:02] <XXCoder> no problem
[21:05:37] <pink_vampire> some parts are born https://i.imgur.com

[21:21:51] <XXCoder> nice :)
[21:22:15] <XXCoder> how was milling it? if I recall right it wasnt too hard, not like nylon
[21:23:39] <pink_vampire> it was like G0
[21:24:12] <XXCoder> fast eh. nice
[21:24:28] <XXCoder> dont try that with nylon it will fuse tool to block
[21:25:08] <pink_vampire> originally it was design to be in aluminum
