#linuxcnc Calendar

01:03 AM Deejay: moin
01:33 AM roycroft: yes
01:36 AM XXCoder: nice
01:36 AM XXCoder: always heard kicad is good one
01:36 AM XXCoder: just never needed it
01:36 AM roycroft: qelectrotech is much better suited to what i need to do, except it does not work right
01:37 AM roycroft: kicad does schematics, but it's very oriented towards making pcbs
01:37 AM XXCoder: its why it was made irrc
01:37 AM roycroft: yes
01:37 AM roycroft: and it looks like it does a really good job at that
01:37 AM roycroft: but i'm not going to be making pcbs
01:39 AM XXCoder: ok
01:39 AM roycroft: i just need to make a wiring diagram for my cnc router
01:39 AM roycroft: and lay out the component placement in the control box
01:40 AM roycroft: i'll spend some more time with kicad tomorrow
01:40 AM XXCoder: :)
01:41 AM roycroft: and i think i'll probably spend enough time with it in the future to start using it for wiring diagrams, but i may end up deciding tomorrow to just use autocad, as i've always done
01:48 AM roycroft: so the cyberninjas report is coming out tomorrow
01:48 AM roycroft: cnn report that it will show that biden got more votes in maricopa county than were officially reported, and the the former president got less than were formerly reported
01:48 AM roycroft: that would be a spectaular backfire
01:49 AM XXCoder: recount thing?
01:51 AM roycroft: yes
01:54 AM XXCoder: yeah i have comments but dont really want to say it here
01:55 AM sync: roycroft: I think qelectrotech will be better suited for what you want to do, especially because it actually has the relevant symbols
02:08 AM mrec_: did anyone ever had the problem that the axis 3d view is not updating?
02:09 AM mrec_: after restarting axis it came back again
02:10 AM mrec_: it only updated when clicking into the view area and dragging around with the mouse
05:09 AM JT-Cave: morning
05:09 AM XXCoder: yo
05:09 AM XXCoder: https://www.prusaprinters.org/prints/76730-lack-enclosure-vent-fan-with-duct-for-120-mm-stand
05:09 AM XXCoder: i made a nice design heh
05:59 AM JT-Cave: going to Hermann today
02:05 PM roycroft: is raspbian the thing to install on my rpi4 for linuxcnc?
02:05 PM roycroft: and if i'm going to be using a mesa ethernet card, do i need to built a real-time kernel for the pi?
02:06 PM roycroft: and happy friday :)
02:09 PM CaptHindsight[m]: roycroft: Andy posted a complete image for the RPi3
02:09 PM CaptHindsight[m]: sorry rpi4
02:09 PM roycroft: where?
02:09 PM roycroft: at linuxcnc.org?
02:13 PM roycroft: aah, i see it right in the downloads section
02:13 PM roycroft: perfect
02:14 PM CaptHindsight[m]: just about everyone misses the link
02:21 PM CaptHindsight[m]: https://www.youtube.com/watch?v=jct3f92rIOE
02:35 PM roycroft: i guess i'll have to dig out an hdmi display and keyboard
02:36 PM roycroft: the raspberry pi imager doesn't let me set the networking parameters on andy's image
02:37 PM CaptHindsight[m]: simple install for simple users
02:38 PM roycroft: it's ok
02:38 PM roycroft: i like setting up the network before the install so i can run it headless
02:39 PM roycroft: but i think i know where there is an hdmi display i can use to finish setting it up
02:39 PM roycroft: and it's probably expecting too much for the imager to be able to customize random third-party images
02:48 PM CaptHindsight[m]: https://www.youtube.com/watch?v=g_-PKSPbvpw
04:22 PM roycroft: well that sucked
04:22 PM roycroft: after i had to make a run to best buy to get a usb c charging cable, because i could not find one here, i come back and that image i burned won't boto
04:22 PM roycroft: i get "error 11: cpu 0 not supported"
04:22 PM roycroft: i guess it's raspbian for now
04:23 PM roycroft: oh wait, it cycled four times with that error and now it boots
04:23 PM roycroft: that's odd, but much better
04:35 PM TurBoss: hello roycroft is a linuxcnc rpi image issue but Im not sure if has any effect
04:37 PM roycroft: i suspect that if it's based on raspbian, it's probing cpu type to detect the architecture on which it's running
04:37 PM roycroft: it did it again when i rebooted after configuring networking
04:38 PM roycroft: so i suspect it's going to continue to do that
04:38 PM roycroft: and that's fine, as long as it boots eventually
04:38 PM roycroft: i just was not aware of the issue when i first powered on the pi
04:38 PM roycroft: so i thought the image was broken
04:39 PM roycroft: i was just not patient enough with it :)
04:39 PM TurBoss: is fine it does always :D
04:46 PM roycroft: i just need to get it set to a static ip now
04:47 PM roycroft: and it doesn't find the network if i'm not broadcasting my ssid, which i usually don't
04:47 PM roycroft: so i'll have to get that sorted - i have done it with debian before, but i forget how i did it
04:48 PM roycroft: then the fun begins - running linuxcnc with x forwarding
04:53 PM roycroft: that was way too easy
04:58 PM -!- #linuxcnc mode set to +v by ChanServ
05:44 PM roycroft: linuxcnc is not happy when i do x forwarding
05:44 PM roycroft: it crashes every time, usually at a differnt point
05:44 PM roycroft: that is not encouraging
05:45 PM CloudEvil: You can in principle do local headless X to a fake buffer, and then VNC
05:45 PM CloudEvil: (or similar)
05:46 PM CloudEvil: I have used dxpc - diffferential X protocol compressor in the past - and I assume there are more modern versions
05:46 PM roycroft: i'll have to spend some more time with it
05:46 PM roycroft: that could be an option though
05:46 PM roycroft: i was hoping that once i got x forwarding working it would just work
05:46 PM roycroft: my concern was more about performance, not whether it would crash
05:47 PM roycroft: i'm using my imac as the x server at the moment
05:48 PM roycroft: my intent is to use an acer laptop running debian as the x server eventually
05:48 PM roycroft: that might work better
05:49 PM roycroft: i've never used dxpc that i recall
05:49 PM roycroft: would i have to run it on both the x server and x client machine?
05:50 PM CloudEvil: I last used it 15 years ago.
05:50 PM CloudEvil: yes
05:50 PM roycroft: then that will have to wait
05:50 PM CloudEvil: at that time
05:50 PM roycroft: there's a debian port that i can install on the pi trivially
05:50 PM CloudEvil: Android also has some X servers IIRc
05:50 PM roycroft: but i don't want to deal with compiling it for the imac
05:51 PM roycroft: i think my next step will be getting that acer laptop set up
05:51 PM roycroft: it even has a touch screen, so there's a possiblity i could use touchy on it
05:52 PM roycroft: i could even skip using the pi completely, and just string an ethernet cable from the laptop to the cnc router, and run linuxcnc directly on the laptop
05:52 PM roycroft: the pi and x forwarding seemed a potential elegant solution that i could use with multiple machines, though
05:52 PM roycroft: i thought it worth a go or two
05:53 PM roycroft: anyway, linuxcnc seems to fun fine on the console, so it's definitely an x forwarding thing
06:43 PM JT-Shop: nice ride today to Hermann
07:44 PM roycroft: are you converting a sausage maker to cnc?
10:31 PM _unreal_: sigh
10:31 PM _unreal_: dont know what I want to do
10:31 PM _unreal_: I do have a small cnc project to do this weekend though
10:32 PM _unreal_: hum
10:32 PM _unreal_: quiet tonight
10:32 PM roycroft: i just finished dinner
10:33 PM roycroft: i'm ready to get back to running linuxcnc on a rpi with x forwarding to a laptop
10:33 PM XXCoder: heyy wheres my dinner
10:33 PM _unreal_: if its not meatloaf I dont want it
10:33 PM roycroft: whereever you left it :)
10:33 PM roycroft: it's friday night
10:33 PM roycroft: so pizza night
10:34 PM XXCoder: lol
10:34 PM _unreal_: I have not made pizza in for ever...
10:34 PM roycroft: tonight's was quite good
10:34 PM roycroft: red sauce, with caramelized onions, anchovies, and black olives
10:34 PM roycroft: the cheeses were 2/3 fontina, 1/3 mozzarella
10:35 PM roycroft: and when it came out of the oven i topped it off with fresh basil and arugula
10:35 PM XXCoder: me, 4 susage patties and cheese slices melt, with small amount of taco sauce. 4 grams carb
10:35 PM XXCoder: all from taco sauce
10:36 PM roycroft: pizza has too many carbs
10:36 PM XXCoder: sadly
10:36 PM roycroft: but i fasted all day to make up forit
10:37 PM XXCoder: i only ate 6 carbs so far today
10:37 PM roycroft: and actually, i've made low carb pizzas before
10:37 PM roycroft: with a zucchini crust
10:37 PM XXCoder: it sucks that only chrunchy chips choice I have is pork rinds
10:37 PM roycroft: you like interesting youtube channels, xxcoder
10:38 PM roycroft: in case you don't watch it already, check out engelscoachshop
10:38 PM _unreal_: baked chicken... had the kid do the labor :)
10:38 PM _unreal_: she's got to learn some how
10:38 PM roycroft: the guy is a wheelwright - one of the last in the world
10:38 PM XXCoder: ok looking
10:38 PM roycroft: he restores buggies from the 19th century
10:38 PM _unreal_: getting scary though 12yo and she's coming into a 16yo body :S
10:38 PM roycroft: it's a great channel
10:38 PM roycroft: i've been watching him for years
10:38 PM XXCoder: looking at one now
10:39 PM roycroft: i think you'll enjoy his videos
10:39 PM roycroft: that is the really scary age, _unreal_
10:39 PM roycroft: their minds are very much still 12 years old
10:39 PM roycroft: but their bodies attract much older boys
10:40 PM XXCoder: ?
10:40 PM roycroft: and they don't have the skills yet to know they're being looked at like that
10:40 PM _unreal_: clueless
10:40 PM _unreal_: not even a question
10:41 PM roycroft: i raised a very beautiful girl who started blossoming when she was 11
10:41 PM roycroft: from then until she was 18 it was really scary for her mother and me
10:41 PM roycroft: but especially in the tween years
10:42 PM _unreal_: does not help. I did clothing modeling for AMES as a kid. and my Xwife is half native american, and half Portuguese
10:43 PM _unreal_: btw my xwife never did well with the fire water
10:43 PM _unreal_: LOL
10:44 PM _unreal_: OMG... soo annoying, I'm supposed to do a CNC job and the guy still has not gotten me the document. I bet he sent it to the wrong email address
10:46 PM roycroft: so it appears, from what little i've found so far in forum posts on the subject, that at least a couple folks have run linuxcnc on a rpi with x forwarding
10:46 PM roycroft: so there's hope for that
10:47 PM _unreal_: I have linuxcnc running on a tinkerboard just fine
10:47 PM roycroft: it's the x forwarding that's the issue
10:47 PM roycroft: not running it on a pi
10:48 PM roycroft: it's crashing on me randomly
10:50 PM roycroft: linuxcnc, that is
10:51 PM roycroft: and it runs fine on the console, so there's no problem with the pi or the installation
11:02 PM Bleepshop: roycroft: You using 'ssh -X <machine>' ?
11:02 PM roycroft: yes
11:02 PM roycroft: the forwarding works
11:02 PM roycroft: but linuxcnc crashes after a bit
11:03 PM Bleepshop: Pi3 or Pi4?
11:03 PM roycroft: pi4
11:03 PM roycroft: using andypugh's build
11:03 PM roycroft: except i updated debian - his build is 10.7, and i went to 10.10
11:04 PM roycroft: it tried automaticaly updating post-install but his image is kind of broken
11:04 PM Bleepshop: roycroft: That'll do it... Updating breaks shit for silly reasons.
11:04 PM roycroft: he made it before bullseye was released, and raspbian have changed the name of the buster train from stable to oldstable
11:04 PM roycroft: but it runs fine on the console, bleepshop
11:04 PM roycroft: it's just with x forwarding that it breaks
11:05 PM roycroft: and so far, i've only done it with an x server running on my imac
11:05 PM roycroft: i'm getting a laptop ready to try soon - it has debian installed on it
11:05 PM Bleepshop: roycroft: Yeah, IIRC the network on those is branched off the USB and the loads will throw the timing loops off resulting in an isecure seeming connection.
11:06 PM roycroft: this is why i am testing before i've even finished the design of the machine
11:06 PM roycroft: i really want to run it headless
11:07 PM roycroft: but if i am going to need a physical console i need to plan for that
11:07 PM Bleepshop: I ditched the idea of a Pi for now untill I can get the FPGA board worked over as a Mesa clone.
11:07 PM roycroft: i'm going to get a 7i96 when jt gets them back in stock in a few weeks
11:08 PM Bleepshop: roycroft: Laptop and a holster for it on the machine? Pop it open when you really need the console?
11:08 PM roycroft: if i have to
11:08 PM roycroft: headless with x forwarding over wifi would be ideal
11:09 PM roycroft: and i have some time to try to get to work still
11:09 PM roycroft: but this acer laptop that has debian on it could run linuxcnc and talk to the mesa board via etherent
11:09 PM Bleepshop: And be hidden till you need it non-headless.
11:14 PM roycroft: and this laptop does not want to boot
11:14 PM roycroft: it worked fine the last time i used it, but that's been a couple months
11:15 PM XXCoder: tapped battery?
11:18 PM roycroft: i'm trying to see if the power adapter is working, but it took me a while find a fluke
11:18 PM roycroft: and the center pin is so small i need a needle or paper clip to get into it
11:24 PM roycroft: it's the power adapter
11:24 PM roycroft: hopefully i can find a new one at the goodwill tomorrow
11:27 PM roycroft: they're $10 with free shipping on ebay, so that's my other option if i can't find one locally
11:31 PM _unreal_: man that was odd. had to go to the bathroom. did what I had to do. next thing I know I had a zero pain pin hole cut on my WAY upper inner thigh. that must have been directly connected to a vein. because BOY did it bleed.
11:32 PM _unreal_: I soaked though a lot of TP. I finally said f-- this and put some rubbing alcohol on a facecloth and held it. THEN it started to hurt and stopped bleeding like a min later... but WTF...
11:50 PM XXCoder: not too bad
