12:05 AM Unterhaus__ is now known as Unterhausen
12:26 AM lcnc-relay: <meisterdippel@> moin
12:30 AM roycroft: i just got an image copied onto a microsd disc
12:31 AM roycroft: i'll know presently if it works, but then there is the testing to see if linuxcnc works properly
01:03 AM Deejay: moin
04:45 AM Tom_L: morning
06:43 AM lcnc-relay: <travis_farmer@> Morning
07:00 AM rdtsc-w: roycroft, use the .xz image from Tom's link, but make sure you use Raspberry Pi Imager software to write it. I really wanted to use Balena Etcher but for whatever reason, that would always cause issues, possibly the same for other burning software.
07:01 AM rdtsc-w: Also, if the Rpi has an old firmware on it, that might have something to do with it... forget the command but there is a way to update it... firmware-update or something like that
07:03 AM JT-Cave: I quit using etcher and started using gnome disk writer
07:09 AM bjorkintosh: balena etcher gave me all kinds of errors. I just use dd
07:20 AM JT-Cave: Disk Destroyer!
07:20 AM JT-Cave: etcher would change the default program for html to itself... how annoying
07:23 AM bjorkintosh: dd is highly underrated.
07:39 AM lcnc-relay: <meisterdippel@> cat
08:15 AM JT-Cave: time for a ride
09:19 AM rdtsc-w: can use dd, but default blocksize is slow for TF (micro SD) cards (2x speedup or more for those in-the-know)
09:47 AM roycroft: i did use the .xz from tom's link and i did use raspberry pi imager
09:48 AM roycroft: and i've successfully done the install using those tools in the past, with previous versions of linucnc
09:48 AM roycroft: i've also scribbled .iso mages to microsd cards with dd
09:48 AM roycroft: and i know how to set a reasonable blocksize when doing that
09:48 AM roycroft: i learned that trick with cd-rs first came out
09:56 AM roycroft: and that is a sign of old age - i'm talking about a technology that is obsolete and unknown to many folks today when it "first came out"
11:44 AM rdtsc-w: Check out Binner for parts/stock/BOM management; free version supports 192 bins - https://github.com/replaysMike/Binner
11:47 AM roycroft: i have an idea about why my compressor motor failed
11:47 AM roycroft: back when i got the motor i still had the original compressor pump, and the original motor, while 5hp, had a 5/8" shaft, so i replaced it with one with a 5/8" shaft
11:48 AM roycroft: i since upgraded to a 2-stage compressor pump, also 5hp, but when i peruse various motor and compressor pump websites, i see that virtually all 2 stage pumps use a motor with a 7/8" shaft
11:49 AM roycroft: as well, the single stage pumps usually have a single sheave, while the 2 stage pumps generally have a double sheave
11:49 AM roycroft: i'm thinking the 5/8" shaft does not hold up well with a double sheave
11:50 AM roycroft: that the motor lasted 20+ years like that is a testament to the quality of the motor, but it may have been undergoing stresses it was not designed for the whole time, and finally failed
11:50 AM roycroft: does that explanation seem plausible?
11:51 AM xxcoder: morning. glad to have ups lol no power here.
11:51 AM roycroft: why is the power out? is the weather too nice for the power company to be bothered to do their job?
11:51 AM xxcoder: its mist rain here currently
11:52 AM xxcoder: sadly seems behind on payment
11:52 AM roycroft: sunny up here, but mist in the valley, i think
11:52 AM roycroft: bummer on that
11:52 AM roycroft: your ups won't last indefinitely, so hope that gets sorted soon
11:53 AM xxcoder: yep. very nice lifepo4 upgraded ups, but lasts around 3 hours
12:11 PM Rab: 5/8" shaft seems really wimpy to me. I bought a 3hp motor and the shaft was 1-1/8! An air compressor isn't the easiest duty, either.
12:17 PM roycroft: so you think my hypothesis is plausible
12:18 PM Rab: I do.
12:18 PM roycroft: if i decide it is, then i won't bother getting a quote on repairing the existing motor - refitting it with a larger diameter shaft would cost more than a new motor
12:18 PM JT-Shop: usually they don't rebuild motors under 20 hp
12:18 PM JT-Shop: what frame motor is it?
12:19 PM Rab: I'd be on the lookout for a surplus or second-hand motor.
12:19 PM roycroft: and actually, a 5hp motor with a 5/8" shaft is a "special duty" motor, and is less common and much more expensive than one with a 7/8" shaft
12:19 PM roycroft: 56
12:20 PM JT-Shop: https://www.amazon.com/VEVOR-5HP-Compressor-Electric-Motor/dp/B0C5N7P1CY
12:20 PM JT-Shop: $154
12:21 PM roycroft: yeah, i saw the vevor
12:21 PM roycroft: vevor make everything these days, it seems
12:21 PM JT-Shop: too many 1 star reviews though
12:22 PM Rab: Hmm, the 5hp is cheaper than the 3.7hp.
12:23 PM roycroft: https://roycroft.us/CompressorPump.pdf
12:23 PM roycroft: that's what i'm driving with the motor
12:23 PM roycroft: i have the APP3Y0521T
12:24 PM roycroft: so i'm thinking new motor and new double sheave
12:24 PM roycroft: i'll get on ordering that stuff soon
12:29 PM * JT-Shop has a 3/4hp, 1 1/2hp and a 3hp motor in stock but no 5hp...
12:29 PM Rab: I have been operating under the assumption that any cheap chinesium I want from Amazon needs to be quickly ordered from current stock.
12:31 PM roycroft: a valid assumption
12:32 PM Rab: I suspect a lot of market uncertainty is being buffered by people buying quick and cheap while they still can. Once existing inventory is depleted and prices rise, the market will crater, fast.
12:35 PM roycroft: the sheave is proving difficult to find
12:36 PM roycroft: i suppose i could bore my existing one out, but my milling machine is still in storage, i don't trust that my drill press would be accurate enough, and i don't have a 7/8" broach for the keyway
12:36 PM JT-Shop: check into a QD bushing type
12:36 PM roycroft: aah, i found one
12:37 PM roycroft: https://robidouxinc.com/collections/pulleys/products/3-5-cast-iron-dual-groove-pulley-a-belt-4l-style-for-7-8-shaft
12:37 PM roycroft: and i was thinking it would cost about $40
12:37 PM roycroft: so depending on what they charge for shipping, that would be fine
12:37 PM roycroft: oh, that's for an a belt, and i need b belt
12:38 PM roycroft: they have one for a b belt
12:38 PM Rab: I've bought a bunch of pulleys from eBay over the last couple of years. I've found it very economical to get a good deal on a bushed pulley, and then find the right bushing for the pulley and the bore size.
12:38 PM Rab: $40 all told is pretty cheap though.
12:39 PM roycroft: free shipping :)
12:39 PM roycroft: and that's a nice, cast iron sheave
12:43 PM roycroft: so that's done, now to find a motor
12:44 PM roycroft: i'm 99.9% certain the old motor was 3450rpm, but i'm going to pull it and confirm before i order a new one
12:44 PM roycroft: this would probably be a good time for me to do a hydrostatic pressure test on the tank, which i've never done
12:45 PM roycroft: the problem is that my pressure washer is not working properly, so i'd need to repair that first, or borrow/rent one for the test
12:47 PM lcnc-relay: <roguish> if you fill the tank to test with water, then just presurize it air, that's ok. not much air to explode.
12:47 PM lcnc-relay: <roguish> just a few bubbles....
12:48 PM rdtsc-w: Fill it with soapy water though... rocket!
12:48 PM rdtsc-w: 3450:820 implies a gearing of 4.21:1, whereas 1745:820 implies 2.13:1
12:48 PM roycroft: i'll spend a little time with the pressure washer first, though
12:48 PM roycroft: it runs, but it stalls when i kick in the high pressure pump
12:48 PM roycroft: i suspect the carburettor is varnished, or there is debris in the pump line
12:49 PM roycroft: the machine has like 15 hours of use
12:49 PM roycroft: but it sat for a couple years with a full tank of gas, and did not run well after, which is why i suspect varnish in the carb
12:50 PM roycroft: the problem with using air for the hydrostatic test is that i need to test it to 1.5 times the working pressure, and i have been maintaining a working pressure of 150psi, so i would need 225psi
12:50 PM roycroft: and i don't have a compressor that goes that high
12:51 PM rdtsc-w: just shredded a defunct LCD... could not get it off adhesive on good touch-glass, so gutted it and now peeling frame from TSG
12:53 PM roycroft: i don't know what ratio the current setup is, as i don't know the diameter of the pump flywheel
12:54 PM roycroft: but it's not much more work to pull the old motor than to measure the flywheel diameter, and i need to pull the old motor anyway, so that's what i'll do
12:54 PM Rab: I wonder what happened to Loetmichel...hasn't been here since July of last year.
12:54 PM roycroft: but the flywheel is certainly closer to 12" than 6"
12:55 PM roycroft: hopefully he's still with us, but distracted by other things
01:04 PM roycroft: what i really need to do is figure out why the current linuxcnc distro won't boot on my rpi4
01:05 PM roycroft: i want a premium motor for the compressor, such as a leeson or baldor, but those are $600+, so i'll probably end up getting a sub-$200 import and hope it lasts a while
01:05 PM roycroft: the sheave is ordered, and it should not take long to pick out a motor
01:26 PM lcnc-relay: <skunkworks8841@> I had recently installed the latest image on a rpi5.. I could certainly try the current rpi4 image on one of the 4's I have here
01:39 PM roycroft: i'll give it another go this evening
01:40 PM roycroft: the big problem is that when i boot the rpi, some penguins show up on the top of the screen, then four lines of text, which disappears faster than i can read a single word
01:40 PM roycroft: and then the screen is blank
01:40 PM roycroft: i'm thinking i should set up the gopro, aimed at the screen, and see if it can capture the messages and give me a clue
01:41 PM lcnc-relay: <skunkworks8841@> Which hdmi port do you have the monitor pluggeed in? Should be the one closest to the power.
01:42 PM lcnc-relay: <skunkworks8841@> (should not matter - but I have certainly had odd issues when I plugged it into the second)
01:42 PM roycroft: the old linuxcnc card with i think 8.1 works fine
01:42 PM roycroft: i think it's the one next to the power - i'll check in a minute
01:43 PM roycroft: yes, it's the one next to the power
01:44 PM roycroft: i had the 7i96 connected to the ethernet jack, but i unplugged that
01:44 PM roycroft: it should not have affected booting raspberry pi os, but i unplugged it anyway
01:45 PM roycroft: there is an analog relay hat plugged into the rpi, but again that worked fine with an older version of the os
01:45 PM roycroft: i can try removing that temporarily
01:45 PM roycroft: it's screwed into the pi, and is enough trouble to remove that i'd rather not unless i have a good sense that it might be the cause of the problem
01:45 PM * roycroft thinks he needs to find his gopro and make sure it's charged
01:46 PM roycroft: the linuxcnc machine itself nor the os are not what i anticipated having problems with - that kind of stuff i know like the back of my hand
01:47 PM roycroft: i anticipated i might have a few stumbling blocks when configuring hte 7i96 and building the hal config for the machine
01:47 PM roycroft: but i'm nowhere near that point yet
01:52 PM lcnc-relay: <skunkworks8841@> the only other thing I can think of - is the power supply have enough current?
01:52 PM roycroft: i can give it as much as it wants
01:53 PM roycroft: it's a bench power supply
01:53 PM roycroft: and again, the same pi works fine with the older os
01:53 PM roycroft: with the same power supply
01:53 PM roycroft: all i did was swap microsd cards
01:54 PM roycroft: and i've put the old one back in to ensure that i did not screw something up and it still boots file
01:54 PM roycroft: fine
01:56 PM roycroft: and the gopro won't boot up
01:56 PM Rab: Sounds like it's switching console resolution right after the kernel boots, and the monitor doesn't like it. Has this Pi worked with this monitor before?
01:56 PM roycroft: i have no indication that it's even charging, but it should work and has worked without a battery if it's plugged into a usb power supply
01:56 PM roycroft: yes, rab
01:56 PM roycroft: again, it works fine with the linuxcnc 8.1 distro, which i believe is debian 10 based
01:57 PM lcnc-relay: <skunkworks8841@> Try ctrl-alt-f1
01:57 PM lcnc-relay: <skunkworks8841@> see if you get console
01:57 PM roycroft: you may be correct about that, but i don't recall debian ever switching resolution that early in the boot cycle
01:57 PM roycroft: good idea, skunkworks8841
01:58 PM roycroft: aah, the gopro seems to be charging now
01:58 PM roycroft: i just finished lunch, and have a half hour left on my lunch break, but i think i should pull that motor next, and have another go with the rpi if time permits
01:58 PM roycroft: othewise i can deal with it after work
02:03 PM Rab: I see that often with Debian (on amd64). The bootloader comes up in some terrible low resolution mode, the kernel starts in the same mode (with optional per-core penguins), then almost immediately switches to the mode specified in the kernel parameters. But I can't say exactly when that happens, it might be when the root drive is mounted.
02:06 PM Rab: I don't know what Raspbian(?) is like, but in vanilla Debian grub2 has an advanced boot options menu with "safe mode" entries for the installed kernel(s)...might be something to try.
02:07 PM lcnc-relay: <skunkworks8841@> I will say - whatever the latest image for the 5 worked way better than what I was initally using. Super stable.
02:07 PM lcnc-relay: <skunkworks8841@> (and I don't remember what I initally used - might have been comunity built)
02:09 PM Tom_L: Rab, in regard to Loetmichel, iirc someone showed up in his behalf after he left asking a few questions on things he'd been working on. he may have passed
02:10 PM Tom_L: last ping Jul 28 16:14:31 * Loetmichel_ has quit (Ping timeout: 264 seconds)
02:10 PM lcnc-relay: <skunkworks8841@> oof
02:11 PM Tom_L: not sure what year
02:11 PM Rab: Tom_L, thanks for the info, I'm sorry to hear that.
02:11 PM Tom_L: hopefully i didn't mis speak but that's what i recall
02:12 PM Rab: I found that quit message in 2024.
02:12 PM Tom_L: he was the one working on freecad right?
02:12 PM Tom_L: German professor or something
02:12 PM JT-Shop: how to cut up a styrofoam box without making a mess...
02:12 PM Tom_L: JT-Shop, hot wire
02:13 PM JT-Shop: hmm, don't have one
02:13 PM Tom_L: borrow the wire from a toaster :)
02:13 PM rdtsc-w: hot (junk) knife?
02:13 PM Rab: I don't know about freecad. IIRC he worked for a German company EM-hardening consumer-grade IT stuff for, presumably, the intelligence or defense market.
02:13 PM JT-Shop: hmmm
02:14 PM Tom_L: ahh that's right
02:14 PM Tom_L: who was the one working on freecad then?
02:14 PM Rab: He did a lot of really impressive machining with generic little Chinese routers.
02:14 PM Tom_L: i forget
02:14 PM Tom_L: yes
02:15 PM Tom_L: he was always getting injured too
02:15 PM Rab: A hot wire is pretty easy to improvise, steel piano wire or a guitar string might have enough resistance to get pretty warm.
02:16 PM rdtsc-w: a lot of solvents will also "deflate" it, but then yer left with some nasty and flammable goo
02:17 PM Rab: Tom_L, haha, yeah. And destroying vehicles. Hope it wasn't that...
02:17 PM Rab: Napalm!
02:17 PM Tom_L: i think i mixed him up with the other freecad developer
02:18 PM Rab: A heat gun will turn a chunk of styrofoam into a little polystyrene pellet, but that's probably best done outside.
02:20 PM JT-MShop: Weller 8200M worked great
02:33 PM -!- #linuxcnc mode set to +v by ChanServ
02:34 PM roycroft: yes, loetmichael is/was german, and ichguckslive was german
02:34 PM Rab: Yeah, IchGucksLive
02:35 PM roycroft: he is now ichguckstod :(
02:36 PM Tom_L: loetmichael may be out pushing his beater down the road
02:36 PM roycroft: he works had and plays hard
02:36 PM roycroft: hard
02:37 PM roycroft: the gopro is finally charging, so hopefully i'll be able to capture the screen as the rpi starts to boot
02:38 PM roycroft: and hopefully, knowing exacly when the screen goes dark may provide a clue as to what is wrong
02:38 PM roycroft: if this continues to be an issue i'll try a stock raspbian pi os install next
02:39 PM roycroft: and then attempt a preempt-rt kernel
02:40 PM roycroft: pulling the relay hat may not be as much of a hassle as i thought, so i shall try that before reimaging the microsd card again (i've done it three times so far)
02:40 PM roycroft: but it seems highly improbably that hat is the issue, especially since debian 10 runs fine on the pi
02:46 PM Tom_L: roycroft, if i remember right, there is a debian 12 install for rpi that you can then install linuxcnc on but it's been quite a while since i messed with the rpi
02:46 PM Tom_L: possibly thru package manager
02:47 PM -!- #linuxcnc mode set to +v by ChanServ
02:48 PM roycroft: i want to spend a little more time troubleshooting the stock image from the downloads page before moving on to something else
02:48 PM roycroft: perhaps i'll discover something that would be helpful to the community
02:48 PM Tom_L: it should work however that's not how i did my install
02:48 PM Tom_L: that came later
02:49 PM roycroft: first thing i need to do is determine exactly where in the boot sequence it fails
02:49 PM roycroft: the gopro is at 6% charge, and it's been plugged in for about an hour
02:49 PM roycroft: that's some slow battery charging
02:59 PM Tom_L: i have an img from '23 with bookworm/lcnc 2.9.2 on it
03:00 PM Tom_L: 6.1.54 kernel
03:00 PM Tom_L: it appears
03:01 PM Tom_L: if you have troubles, that might get you goin
03:06 PM Tom_L: could probably do an upgrade from that
03:13 PM roycroft: thanks
03:13 PM roycroft: i'll let you know
03:44 PM roycroft: well that's annoying as hell
03:44 PM roycroft: i went to the trouble of setting up the gopro, rearranging things so the video was decent, recorded the boot sequence of the old version, then plugged in the current version's flash card, and this time it worked
03:45 PM roycroft: i've booted that sd card at least a dozen times, and it always hung afer the first 4 lines of boot messages
03:45 PM roycroft: OOOHHHH
03:45 PM roycroft: i did make a change
03:45 PM roycroft: i had a usb hub plugged in before
03:46 PM roycroft: when i rearranged the hardware (i moved the pi so it would be in the shot along with the screen) i removed the usb hub and plugged the mouse and keyboard directly into the pi
03:46 PM roycroft: i bet if i plug that usb hub back in it will hang again
04:00 PM roycroft: and while i'm generally not a betting person, i should have made that bet, because when i plug the hub back in it hangs in the same place
04:00 PM roycroft: odd that debian 10 is happy with the hub and debian 12 does not like it
04:00 PM Rab: Interesting.
04:01 PM roycroft: but it's not needed, so i'll just leave it unplugged
04:02 PM roycroft: i don't even remember why it was plugged in the first place - probably because the mouse and keyboard were plugged into the hub, and when i switch machines i only need to move one usb connection, not two
04:02 PM roycroft: nothing but the mouse and keyboard were plugged into it
04:03 PM roycroft: at any rate, i can move forward with the project now
04:04 PM roycroft: i'm assuming my next steps are to talk to the 7i96, use jt's mesaconfig tool to configure it, then generate a hal configuration and wire things up
04:05 PM roycroft: then it should be alive
04:06 PM lcnc-relay: <travis_farmer@> i usualy wire things up, and then do the hal config... but i may be a bit bass-akwards
04:09 PM roycroft: i might do that, but one thing at a time
04:09 PM roycroft: wire, edit config, test, move on to the next
04:10 PM roycroft: i know a lot of folks wire everything up at once and then go into a debugging phase
04:10 PM roycroft: and maybe when i'm more experienced with linuxcnc i'll be able to do that, but for now i think i need to do one thing at a time and test it before moving on
04:14 PM Tom_L: dl the latest mesaflash from linuxcnc.org git
04:14 PM Tom_L: it's more up to date than mainstream copies
04:15 PM roycroft: ok, thanks
04:28 PM roycroft: which reminds me that the very next thing i need to do is get wifi working on the rpi
04:36 PM JT-Shop: roycroft, you should be able to create the complete configuration with Mesa CT
04:36 PM JT-Shop: as well as flash the 7i96
04:36 PM JT-Shop: Tom_L, does mesact run on the rpi?
04:45 PM roycroft: i'll findo out in a bit, jt-shop
04:46 PM roycroft: i am waiting for an email from microsoft at the moment
04:46 PM roycroft: and given their concept of time, that might take hours
04:46 PM roycroft: so i'll go out and start working on networking the rpi while i'm waiting
04:47 PM roycroft: i'm thinking i want the mini-router to start moving today
04:48 PM * roycroft likes setting ambitious goals
05:03 PM roycroft: so menu-config is annoying - it does not respect the EDITOR environment variable, and locks one into using nano, which i find hopelessly frustrating
05:03 PM roycroft: i do not mind when things default to nano, but i need to use my editor of choice
05:05 PM * JT-Shop finally shot the 12 cans of soda that taste like crap
05:31 PM Tom_L: JT-Shop, i'm not sure i've ever tried that
05:39 PM JT-Shop: pretty satisfying if they are still carbonated
05:46 PM roycroft: is measct gui app?
05:47 PM Tom_L: yuyp
05:48 PM roycroft: ok, then i'll need to run it on the console, or install vnc
05:48 PM roycroft: i'm in my office now, doing basic config via an ssh session
05:48 PM roycroft: thanks
05:59 PM Tom_L: JT-Shop, verified mesact runs on rpi4 debian12 64bit
06:00 PM Tom_L: 2.1.7
06:01 PM -!- #linuxcnc mode set to +v by ChanServ
06:01 PM Tom_dev: Linux raspberrypi 6.1.54-rt15 #1 SMP PREEMPT_RT Fri Nov 17 17:02:27 AEST 2023 aarch64 GNU/Linux
06:02 PM Tom_dev: linuxcnc 2.9.3
06:02 PM Tom_dev: debian 12.8
06:04 PM Tom_L: and roycroft i _have_ cut chips with that setup
06:04 PM roycroft: i'm doing system upgrades now, and installing the prerequisites for mesact
06:05 PM roycroft: hopefully i'll be making chips, or at least sawdust, soon
06:05 PM Tom_L: if you install the deb you shouldn't have to
06:05 PM Tom_L: it should gather what you need iirc
06:06 PM roycroft: jt's documentation suggests that i should do it
06:06 PM Tom_L: ahh ok, i haven't done much with mesact for quite a while
06:06 PM roycroft: it may work without doing so, but i'm going to follow his instructions
06:06 PM Tom_L: not a bad idea
06:06 PM roycroft: i need to finish the system upgrades first though, and that's going to take a while longer
06:07 PM Tom_L: yup
06:07 PM roycroft: all that stuff is slower on a rpi
06:07 PM roycroft: and there are heaps of updates
06:08 PM Tom_L: i wanted to verify it installs in case you do run into problems
06:08 PM roycroft: my sheave will be here in a couple days, and i have an offer in on a motor
06:08 PM roycroft: thanks, i do appreciate it
06:08 PM roycroft: if something goes wrong i can blame myself and not jt :)
06:09 PM Tom_L: i haven't build a deb on the rpi in quite a while now that i cross compile them on the amd64
06:09 PM Tom_L: goes alot quicker
06:09 PM roycroft: i should not need to do this often, and i am patient
06:10 PM Tom_L: once you get the config you really won't need mesact
06:10 PM roycroft: and it feels like nap time, so perhaps that would be a good thing to do while waiting for the updates to complete
06:10 PM roycroft: yeah, once the 7i96 is flashed i should be good
06:10 PM roycroft: and if i need to tweak my hal config i can do that manually
06:10 PM Tom_L: https://github.com/linuxCNC/mesaflash
06:11 PM Tom_L: git clone that and cd to the folder and sudo make install
06:11 PM Tom_L: that will get you the latest mesaflash
06:11 PM Tom_L: you will have to install 2 maybe 3 libraries
06:11 PM Tom_L: but they are listed in the readme
06:12 PM Tom_L: sudo apt install libpci-dev libmd-dev pkg-config build-essential git
06:12 PM roycroft: my gopro is finally charged
06:12 PM roycroft: now that i don't need it
06:13 PM roycroft: but perhaps when i first try to bring the mini router to life it would be fun to record that attempt
06:13 PM Tom_L: https://github.com/LinuxCNC/mesaflash/blob/master/README.md
06:13 PM Tom_L: i have copies of most of those versions
06:14 PM roycroft: ls
06:14 PM roycroft: ack
06:14 PM Tom_L: nak
06:19 PM roycroft: are you about, t?
06:19 PM roycroft: jt, rather
06:20 PM roycroft: oh, never mind
06:20 PM roycroft: something on my end
06:23 PM roycroft: mesaflash and mesact are both installed now
06:23 PM roycroft: and i need a break
06:23 PM * roycroft decides to go for a short walk
06:33 PM roycroft: when i launched mesact i lost my network connectivity
06:34 PM roycroft: i wonder if it reset the ip address on the wifi interface
06:34 PM roycroft: and if i need to configure the ethernet interface before running it
06:35 PM roycroft: it's been a long time since i've done this, but i'm thinking that is what i need to do
06:59 PM roycroft: i can talk to the 7i96 now, and am figuring out what firmware to flash to it
07:11 PM Tom_L: it should have firmware loaded
07:12 PM Tom_L: may not be quite what you need but it should have some
07:12 PM roycroft: yeah, i found that it does, and since i don't have a daughter board connected at the moment it should be fine
07:12 PM Tom_L: you can do a --readhmid with mesaflash to list the pinouts
07:13 PM roycroft: i'm trying to use mesact, actually
07:13 PM roycroft: which can flash by calling mesaflash
07:14 PM Tom_L: right
07:14 PM Tom_L: it just plugs in the options for you
07:59 PM lcnc-relay: <skunkworks8841@> https://photos.app.goo.gl/NH8daP3zjFZCqmBt8
07:59 PM lcnc-relay: <skunkworks8841@> you'll shoot your eye out!
07:59 PM lcnc-relay: <skunkworks8841@> (it is a red rider bb gun.. )
08:02 PM -!- #linuxcnc mode set to +v by ChanServ
08:02 PM xxcoder: the power is back yay
08:03 PM xxcoder: ups lasted 2 hours and 40 min before forcing pc shutdown'
08:03 PM roycroft: welcome back
08:03 PM xxcoder: wow I can finally feel civilized
08:04 PM roycroft: while you were gone i got my rpi4 working and installed mesaflash and mesact
08:04 PM xxcoder: my curse may have left and helped you
08:05 PM roycroft: i am now working on the configuration of the minirouter
08:05 PM xxcoder: way to go btw
08:05 PM roycroft: it's been a really long time since i've hooked any hardware up to a linuxcnc machine, and i've forgotten almost everything, so i'm relearning from scratch, basically
08:06 PM xxcoder: lol yeah I have basically forgotten everything also. if I need to config again, it'd take me a while also.
08:07 PM roycroft: i've also not done much to clean up/lubricate that machine, so it may not run very well once i get it wired up and configured
08:08 PM roycroft: but the immediate goal is to bring it back to life
08:08 PM xxcoder: biggest issue I had was steppers being bit gimpy, along with meh couplers.
08:09 PM roycroft: all that can be fixed
08:09 PM roycroft: if need be
08:10 PM roycroft: and the thing is, this little machine will never be a production machine
08:10 PM roycroft: so if it's really slow that's fine
08:10 PM xxcoder: it moved pretty reasonable, but not amazing amount of sideforce can be handled
08:11 PM xxcoder: not problem with wood, if theres sideforce something is screwy
08:12 PM roycroft: if i just have to go slow that's not a problem
08:12 PM roycroft: if it misses steps it's a problem
08:12 PM xxcoder: indeed
08:12 PM xxcoder: you will have MUCH easier time tuning it than I had
08:12 PM xxcoder: requires certain sense you have and I dont.
08:13 PM roycroft: i'll have better tools :)
08:13 PM xxcoder: that too
08:15 PM roycroft: i'm having a hard time focusing right now, though
08:15 PM roycroft: a combination of fatigue and hunger
08:15 PM xxcoder: just had meal, hurry up and have one lol
08:15 PM roycroft: so perhaps it would be good to just make dinner and consider getting back to the cnc project later
08:16 PM xxcoder: I usually have meal around 5-6 pm. so power come back just in time for me to already eat half of cold meal. yay?
08:16 PM roycroft: at least it's back on
08:16 PM xxcoder: indeed.
08:17 PM xxcoder: gonna love lifepo4 tho. it used to be 30 min uptime (after lead acid got aged)
08:17 PM xxcoder: charging is riciously slow tho. probably wont be charged for another 5 hours
08:20 PM roycroft: seller just agreed to my offer
08:20 PM roycroft: the motor is ordered
08:20 PM xxcoder: not too expensive hopefully
08:21 PM roycroft: $160
08:22 PM roycroft: i really want a good, american made one like leeson or baldor or marathon, but those are $600+
08:22 PM roycroft: and i can't afford that right now
08:25 PM roycroft: time to make dinner
08:26 PM xxcoder: yeah expensive. well have good dinner
08:32 PM lcnc-relay: <skunkworks8841@> I don't think I have any 5 hp single phase.
08:32 PM lcnc-relay: <skunkworks8841@> although that is a lot easier at 3600rpm
08:48 PM roycroft: xxcoder: did you ever have any limit switches on that mini router?
08:48 PM roycroft: if you did, skunkworks8841, and it was a good american made one, i'd be interested
08:49 PM roycroft: single phase, btw
08:49 PM xxcoder: nope. when I used it, I just moved it to "near ends" then switch it off, hand rotate it to touch, then one rotate back
08:49 PM roycroft: ok
08:49 PM roycroft: i did not see any signs of limit switches
08:49 PM roycroft: i can add them later if i want
08:49 PM xxcoder: I suppose shims would be better for more consient
08:50 PM * roycroft is waiting for onions to caramelize
08:50 PM roycroft: i forgot i had to do that, so dinner is delayed a half hour now
08:50 PM * xxcoder is jealous of hot cooked meal, had to have cold meal in cooler day today
08:51 PM roycroft: no motors that size on cl either
08:51 PM roycroft: cl motors tend to be <1hp or 10hp+
08:51 PM roycroft: few are in between
08:52 PM lcnc-relay: <skunkworks8841@> I can look. I doubt it though. (I have not looked through all the piles of motors
08:52 PM roycroft: i'm still going to get this one i just ordered
08:52 PM roycroft: but if you run across one i'd rather put that in service and keep the one i ordered as a spare
08:53 PM xxcoder: whats your plans with broken one? it may be broken shift but its still functional from what I understand
08:53 PM lcnc-relay: <skunkworks8841@> Sure
08:53 PM roycroft: recycle
08:53 PM roycroft: i don't see any other use
08:53 PM roycroft: and yes, it is perfectly functional
08:53 PM roycroft: other than not having an output
08:54 PM xxcoder: time to make electric bike with it? ;) yeah dont sound very usefyl. maybe try sell for someone who need something like that
08:54 PM roycroft: 5hp, 56 frame, 7/8" shaft with 2.385" stick-out
08:54 PM lcnc-relay: <skunkworks8841@> Yah.. it would be hard to fix a broken shaft..
08:54 PM roycroft: er, 2.375" stick-out
08:55 PM roycroft: if i still had a metal lathe i would try turning a new shaft and installing it myself
08:55 PM roycroft: but i don't, and i don't feel like hanging on to this one until i get a new lathe
08:57 PM xxcoder: I suppose can mount the motor and have it spin away as yopu bore it
09:00 PM roycroft: a 5hp motor shaft needs to be fairly precisely turned
09:01 PM roycroft: i would want to hold <0.001" on something like that
09:01 PM xxcoder: makes sense
09:01 PM roycroft: the slightest imbalance would cause great vibrations
09:02 PM xxcoder: indeed
09:17 PM lcnc-relay: <vetsin@> anyone ever manage a linuxcnc build outside of debian?
09:18 PM lcnc-relay: <vetsin@> i'm mostly interested in uspace build for working on sim/ui type stuff
09:18 PM Tom_L: ubuntu but that was a while back
09:19 PM xxcoder: if you dont need realtime of some kind it should be much easier.
09:19 PM Tom_L: what did you have in mind?
09:20 PM Tom_L: you can install it on nonrealtime debian for sim but you wouldn't get far beyond that
09:20 PM Tom_L: why not debian?
09:21 PM xxcoder: tom whats up with kernel 6.12 and realtime for lcnc? wondering if its being worked on
09:21 PM Tom_L: i dunno
09:21 PM Tom_L: took a week off and haven't really 'gotten back' into it yet
09:21 PM lcnc-relay: <vetsin@> i'm trying to build it into a nix derivation actually
09:21 PM xxcoder: ah yeah need some warmup time eh lol
09:22 PM Tom_L: the projects i had going were pretty much finished up
09:22 PM Tom_L: so i've just been chillin a bit
09:23 PM Tom_L: helping rifraf a bit with a sensory program to detect rpm from an android app
09:23 PM xxcoder: vetsin cool, hope you're successful :D I'd suggest read some of "how to install in linux system" to see what info you can get, in order to get it work on some other linux distro
09:23 PM lcnc-relay: <vetsin@> yeah -- i'm past the configure stage at least -- so many deps for this thing
09:24 PM Tom_L: xxcoder, http://tom-itx.no-ip.biz:443/~webpage/rifraf/S21_test6.jpg
09:24 PM Tom_L: if you have android and wanna play...
09:25 PM xxcoder: unfortunately got no cnc. roy stole it
09:25 PM Tom_L: for spinning a top
09:25 PM Tom_L: or anything that spins
09:25 PM Tom_L: i tested my lathe motor with it
09:25 PM Tom_L: he's just trying to collect data
09:25 PM xxcoder: yeah? thats cool. sadly dont have anything can do that
09:26 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/rifraf/new_top1.jpg
09:26 PM Tom_L: turned out a couple on the lathe to test with
09:27 PM Tom_L: i got 7 min out of one
09:28 PM Tom_L: prompted me to refurbish my lathe a bit
09:28 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/rifraf/lathe_rpm3.jpg
09:28 PM Tom_L: that was one of the lathe motor
09:28 PM xxcoder: nice. brass top
09:28 PM Tom_L: his numbers are off a bit but that's what he's working on
09:29 PM xxcoder: I dont have any tops sadly. I had the inception movie one but it got corroded and I threw it away. it was uber cheap metal
09:30 PM Tom_L: grab a toy one cheap
09:30 PM Tom_L: some of them are real fancy
09:30 PM xxcoder: sadly my budget was blown up for a month
09:30 PM xxcoder: ill see later on though
09:31 PM Tom_L: i haven't had a chance to do much with it the last few days
09:37 PM Tom_L: xxcoder, do you have an android?
09:37 PM xxcoder: yep. can test it later
09:37 PM Tom_L: you can test it on any motor
09:37 PM Tom_L: fan
09:37 PM Tom_L: etc
09:37 PM Tom_L: ac
09:38 PM xxcoder: ahh fan yeah will do later. not feeling it right now
09:38 PM Tom_L: just set the phone on it and watch it graph
09:38 PM Tom_L: np
09:38 PM xxcoder: wheres app tho
09:38 PM Tom_L: i have every version but can link to his site when you're ready
09:38 PM xxcoder: 👍
09:39 PM Tom_L: it changes names as he developes it
09:39 PM xxcoder: lol undecided it looks like?
09:39 PM Tom_L: .apk file that's just like a debian .deb file
09:40 PM xxcoder: ya have sideloaded apk files before
09:40 PM Tom_L: ok
09:40 PM xxcoder: you have to, if you wanna wear pebble watch, and I do.
09:40 PM Tom_L: it just asks permission and scans it
09:40 PM xxcoder: pebble steel forever
09:40 PM lcnc-relay: <skunkworks8841@> Storm is hitting here
09:41 PM xxcoder: https://media.discordapp.net/attachments/1281055965508141105/1366589350758056007/plugin-2025-04-18T01-58-11Z-625186.png?ex=68117f03&is=68102d83&hm=ff0099486a2885f6699cebde1d0cd177020352d914987feffa97b65ebf528496&=&format=webp&quality=lossless&width=873&height=524
09:41 PM Tom_L: we're supposed to get hit with one in the middle of the night
09:41 PM xxcoder: oh dunno it might rain here lol
09:41 PM lcnc-relay: <skunkworks8841@> Internet might drop out
09:41 PM * Tom_L checks the weather report
09:42 PM lcnc-relay: <skunkworks8841@> Depends on how heavy it rains
09:42 PM Tom_L: may not be as bad as they thought
09:44 PM Tom_L: xxcoder, i linked you his site
09:44 PM xxcoder: got it yep. thanks
09:45 PM Tom_L: if you load it check things like screen fit etc
09:45 PM xxcoder: ok
09:45 PM Tom_L: he's had to change a few things for mine so the app fits and looks ok
09:45 PM Tom_L: i've got 2 i'm testing on
09:46 PM xxcoder: maybe tomorrow. not really enough time, I will switch to night mode lighting soon so harder to test stuff then
09:46 PM Tom_L: i'm close to calling it a night anyway
09:46 PM xxcoder: my phone is fancy. moto 5g 2024 lol
09:46 PM Tom_L: S21 S25 here
09:46 PM Tom_L: but the app fits different on both
09:47 PM Tom_L: he's got that worked out for the most part
09:47 PM xxcoder: thats good
09:47 PM xxcoder: I last developed for android quite a while ago lol
09:48 PM xxcoder: nothing fancy
09:48 PM Tom_L: https://desire3d.com/webshop/index.php?rt=product/product&product_id=124¤cy=AUD
09:48 PM Tom_L: pretty fancy stuff
09:48 PM Tom_L: aparently it's popular over there
09:48 PM xxcoder: yeah definitely above my budget lol
09:48 PM Tom_L: me too
09:48 PM Tom_L: for a top
09:49 PM Tom_L: the app is to promote them though
09:49 PM xxcoder: https://media.discordapp.net/attachments/1281055965508141105/1366589350758056007/plugin-2025-04-18T01-58-11Z-625186.png?ex=68117f03&is=68102d83&hm=ff0099486a2885f6699cebde1d0cd177020352d914987feffa97b65ebf528496&=&format=webp&quality=lossless&width=873&height=524
09:49 PM xxcoder: wonder if app would work on that lol
09:50 PM Tom_L: aparently he's using Kotlin
09:50 PM xxcoder: oops!
09:50 PM xxcoder: failed to copy urkl
09:50 PM Tom_L: seems to be 'the' one to use now
09:51 PM xxcoder: https://www.amazon.com/Manzelun-Kinetic-Optical-Illusion-Spinner/dp/B07P6WPNHQ?th=1
09:53 PM Tom_L: you use android studio?
09:54 PM xxcoder: I used different program. forgot name
09:54 PM xxcoder: its been a decade or so
09:54 PM Tom_L: that and Kotlin seems to be the 'goto' nowdays aparently
09:59 PM xxcoder: interesting. well I doubt I will dev for android again but yeah
10:08 PM xxcoder: man I love my trmnl
10:08 PM xxcoder: simple but very nice
11:10 PM roycroft: so canada voted to not become the 51st state
11:10 PM roycroft: good on them
11:32 PM lcnc-relay: <big_kevin420@> i \voted last week
11:32 PM lcnc-relay: <big_kevin420@> it was easier that way
11:46 PM roycroft: it's odd to me that canada has early voting, but it ends a week before the election
11:47 PM roycroft: but yeah, i've heard that early voting turnout was pretty heavy
