04:45 AM Tom_L: morning
05:55 AM JT-Cave: morning
06:50 AM lcnc-relay: <travis_farmer@> Morning
07:01 AM lcnc-relay: <meisterdippel@> it's already lunchtime 🙂
07:01 AM Deejay: indeed
07:07 AM * JT-Cave tries unsuccessfully for two days to replace a qpushbutton with a subclassed myqpushbutton
07:10 AM lcnc-relay: <meisterdippel@> qpushbutton = myqpushbutton
07:11 AM lcnc-relay: <meisterdippel@> hmm, you load it via .ui file .. link to repo ?
07:12 AM lcnc-relay: <meisterdippel@> this: https://github.com/jethornton/flexgui !?!?
07:12 AM JT-Cave: one moment
07:12 AM JT-Cave: and yes I use a .ui file
07:16 AM JT-Cave: https://github.com/jethornton/Indicator
07:16 AM JT-Cave: paint-6.py is the working example you provided me
07:17 AM JT-Cave: indicator.py loads the indicator.ui file and I test the button for property indicator then attempt to replace it
07:18 AM lcnc-relay: <meisterdippel@> PyQt5 and PyQt6 is mixed
07:19 AM JT-Cave: opps
07:20 AM JT-Cave: couldn't see the forest for the trees...
07:23 AM JT-Cave: https://pasteboard.co/SRkuQha8qwpv.png
07:24 AM JT-Cave: https://pasteboard.co/zIu9jsTGcSNB.png
07:24 AM lcnc-relay: <meisterdippel@> fixed ?
07:27 AM JT-Cave: yes, thanks
07:27 AM JT-Cave: second is the designer file, first is the result of replacing the button
07:28 AM lcnc-relay: <meisterdippel@> I have done nothing
07:29 AM JT-Cave: you pointed out my cut and paste error :)
07:30 AM Tom_L: i watched :)

08:13 AM lcnc-relay: <meisterdippel@> i think, the green frame is too much
08:16 AM JT-Cave: yup
10:42 AM lcnc-relay: <skunkworks8841@> well - the SSH connection is still working over starlink ipv6.. So - yay! (works from work)
12:30 PM xxcoder1 is now known as xxcoder
12:40 PM Deejay: re
12:43 PM xxcoder: skunk nice
01:17 PM lcnc-relay: <rhine_labs@> I testified again For #righttorepair in Washington State. This is nearing the end! I think 1 More executive session and a vote!! Lets hope it passes. https://youtu.be/ZvD5lhcOyKs
03:09 PM -!- #linuxcnc mode set to +v by ChanServ
03:40 PM lcnc-relay: <skunkworks8841@> Nice!
04:29 PM xxcoder: that tiny more fully funcional domed cnc mill is apparently $800. ouch.
06:02 PM lcnc-relay: <big_kevin420@> you mean the one in the glass you posted earlier?
06:02 PM lcnc-relay: <big_kevin420@> yeah that one i sae for over $700 when i was looking. i dont think it even moves or anything
06:03 PM xxcoder: yeah that one
06:03 PM xxcoder: it looks so amazing but I rather have real one than that honestly
06:03 PM lcnc-relay: <big_kevin420@> yesh i looked it up a few weeks ago
06:04 PM lcnc-relay: <big_kevin420@> it hjas a lot of detail
06:04 PM lcnc-relay: <big_kevin420@> and i was looking to buy it, but not for $800
06:04 PM xxcoder: other one is less detailed in some ways, but still to expensive at $500
06:05 PM xxcoder: nearly $600 that is
06:07 PM xxcoder: too bad there seem to be no kit for it
06:07 PM xxcoder: machining kit
06:52 PM lcnc-relay: <imagesurgery@> Hiy y'all, I'm starting my LinuxCNC journey *today*, 7i76EU in hand, and I'm … stuck. Cannot for the life of me get the card to connect to the host computer. I've read all the help I can find on the forums, and the Mesa manual is… well… is 'filled with errors' a shared experience? Anyway, it's not helping me as I cannot figure out if it's a jumper issue, IP, something else. I'm fairly experienced in Linux after 20 years,...
06:52 PM lcnc-relay: ... but stumped here.
06:55 PM lcnc-relay: <imagesurgery@> (LED CR4 is lit orange, probably 24V power [which I've tested, seems good]; CR11 is red, and no idea if this is a normal or error state; all jumpers default, except that W4 came down instead of up as in the docs)
06:59 PM lcnc-relay: <skunkworks8841@> you should be able ping the card.. depending on the jumpers - the ip will either be 10.10.10.10 or 192.168.1.121
07:00 PM Tom_L: shipped default is the 192 address
07:00 PM lcnc-relay: <skunkworks8841@> which ever ip you chose - you need to have your adaptor in the computer set to a correct ip also
07:00 PM lcnc-relay: <skunkworks8841@> right
07:00 PM Tom_L: use a dedicated lan card with a cable from it to the mesa card
07:00 PM Tom_L: no routers etc
07:00 PM Tom_L: set up a static ip for the lan
07:01 PM Tom_L: to one of those ranges
07:01 PM lcnc-relay: <skunkworks8841@> W2 W3 IP ADDRESS
07:01 PM lcnc-relay: DOWN DOWN FIXED 192.168.1.121 (DEFAULT)
07:01 PM lcnc-relay: DOWN UP FIXED FROM EEPROM (10.10.10.10)
07:01 PM lcnc-relay: <skunkworks8841@> there is a jerk limited tp now?
07:02 PM Tom_L: if you say so
07:02 PM Tom_L: i haven't looked
07:05 PM lcnc-relay: <imagesurgery@> Thanks y'all but I've done all these steps (default 192... and eeprom 10..., wifi off and only ethernet set to connect, etc.) to no avail. Even tried putting W4 into its marked default location, and did a second round with reboots inbetween (which I know shouldn't be necessary). Any idea how to _test_ each step to see where the problem actually is (other than 'bsak')?
07:05 PM lcnc-relay: <skunkworks8841@> set to connect? You need to set the ip of the nic on the computer to something static - like 192.168.1.33
07:06 PM lcnc-relay: <skunkworks8841@> Tom_L: https://forum.linuxcnc.org/38-general-linuxcnc-questions/55075-scurve-trajectory-planner?start=0
07:06 PM lcnc-relay: <imagesurgery@> I mean 'connect to wifi', wifi is off, hard off. ethernet settings are 'set' in a way that they can 'connect', but yes, using a static, unique ip on the same subnet.
07:08 PM lcnc-relay: <skunkworks8841@> ok!
07:08 PM lcnc-relay: <skunkworks8841@> can you take a picture of the jumpers?
07:08 PM lcnc-relay: <skunkworks8841@> the card is directly connected to your nic in the computer?
07:13 PM lcnc-relay: <imagesurgery@> Direct as the day the cat6 cable was born. https://imgur.com/a/UW99sN3
07:23 PM lcnc-relay: <skunkworks8841@> you currently have the ip set to 10.10.10.10 - what is your nic set to?
07:23 PM lcnc-relay: <skunkworks8841@> can you do an 'ip address' on your computer?
07:24 PM lcnc-relay: <imagesurgery@> no link; computer's ip is set to 10.10.10.1*1*/8
07:25 PM lcnc-relay: <skunkworks8841@> does your computers nic light up?
07:32 PM lcnc-relay: <imagesurgery@> Took a moment… no. Tested by connecting NUC to home network, then they light up, have a successful link in "ip addr", and overall seems as expected, unlike when connected to the Mesa.
07:43 PM lcnc-relay: <skunkworks8841@> could the cable be a cross over? (I don't know if that matters)
07:44 PM lcnc-relay: <big_kevin420@> you have 24v?
07:46 PM lcnc-relay: <imagesurgery@> I have 24v
07:47 PM lcnc-relay: <imagesurgery@> 24.4 according to my meter
07:48 PM lcnc-relay: <imagesurgery@> skunkworks8841@: No, it's a straight cable. I didn't crimp it but I did test it.
07:48 PM lcnc-relay: <skunkworks8841@> wish peter was on here..
07:48 PM lcnc-relay: <skunkworks8841@> if your ethernet port isn't lighting up - that seems odd
07:49 PM lcnc-relay: <imagesurgery@> Are there usually 1 or 2 LEDs on a working 7i76EU?
07:50 PM lcnc-relay: <imagesurgery@> I'm unsure of the red one on CR11
07:53 PM lcnc-relay: <imagesurgery@> Also just tried hooking the Mesa up to the home DHCP enet, and there's no lights on the mesa in that case either. No idea if it should show up anywhere but it doesn't. There's no IP conflict and the subnet is the same, FWIW.
07:56 PM lcnc-relay: <skunkworks8841@> you tried other cables for shits and grins?
07:56 PM lcnc-relay: <skunkworks8841@> I don't have a 7i76 here
07:59 PM lcnc-relay: <skunkworks8841@> this is a 7i97 powered up and connected to the rpi...
08:00 PM Tom_L: did he ping 10.10.10.10?
08:00 PM Tom_L: was afk
08:00 PM lcnc-relay: <skunkworks8841@> the nic doesn't light up - either end I would guess
08:00 PM Tom_L: i had a bad nic on one of mine
08:00 PM lcnc-relay: <skunkworks8841@> https://photos.app.goo.gl/LcqByA9VhzHZsc8Q7
08:01 PM lcnc-relay: <skunkworks8841@> he says the computer connects to a router and works.
08:01 PM Tom_L: is the static ip set?
08:01 PM lcnc-relay: <skunkworks8841@> he says so
08:01 PM Tom_L: (on the right device)
08:01 PM lcnc-relay: <skunkworks8841@> do we believe him.. 😉
08:01 PM lcnc-relay: <imagesurgery@> Do you?
08:02 PM lcnc-relay: <skunkworks8841@> imagesurgery@ - do you see the picture? the nic is lit up..
08:02 PM lcnc-relay: <imagesurgery@> No lights on either end. Tried this cable between host and home net, all is peachy, it gets seen locally via "ip addr" and via the router. No lights on the 7i76EU nic
08:03 PM lcnc-relay: <skunkworks8841@> but - do you have another cable? asking for a friend...
08:03 PM Tom_L: is that an ipv6 address or ipv4
08:04 PM lcnc-relay: <imagesurgery@> Mine is not lit up anywhere; there are 2 lights on my board, CR11 (red) and CR4 (orange). Moving W5 up caused a green light at CR10 but no other changes.
08:04 PM Tom_L: 10.10.10.1*1*/8 looked a little odd to me
08:04 PM lcnc-relay: <skunkworks8841@> either the cable is bad - or the mesa isn't powered correctly - or the mesa card is bad
08:04 PM lcnc-relay: <imagesurgery@> ip4 is all I've been setting;
08:04 PM -!- #linuxcnc mode set to +v by ChanServ
08:04 PM lcnc-relay: <skunkworks8841@> is is correct on discord
08:04 PM lcnc-relay: <imagesurgery@> the * * * are just bold formatting, I mean 10.10.10.11/8
08:05 PM Tom_L: i've noticed some like the netmask specified and some will accept 10.10.10.1/24 etc
08:05 PM lcnc-relay: <skunkworks8841@> it should light up just plugging it in - if the mesa card is on.
08:06 PM lcnc-relay: <imagesurgery@> I would think so too, esp. if hooked to a working network
08:06 PM Tom_dev: auto enp2s0
08:06 PM Tom_dev: iface enp2s0 inet static
08:06 PM Tom_dev: address 10.10.10.1
08:06 PM Tom_dev: netmask 255.255.255.0
08:06 PM Tom_dev: taken from one of mine
08:07 PM Tom_dev: then sudo systemctl restart NetworkManager.service
08:07 PM Tom_dev: to activate it
08:07 PM Tom_dev: that also varies
08:08 PM Tom_dev: an alternate entry: interface eth0
08:08 PM Tom_dev: static ip_address=10.10.10.11/24
08:11 PM Tom_L: both of those are known to work but the os may dictate which one it likes
08:11 PM Tom_L: the first one is on a debian12 install
08:11 PM Tom_L: your device name will vary
08:12 PM lcnc-relay: <skunkworks8841@> this is my 7i96 powered by usb from my laptop - just plugged into my laptop ethernet.
08:12 PM lcnc-relay: <skunkworks8841@> https://photos.app.goo.gl/rxTnbKBn8XvaPGvY7
08:12 PM lcnc-relay: <skunkworks8841@> windows
08:12 PM lcnc-relay: <skunkworks8841@> you have a link problem.
08:12 PM lcnc-relay: <imagesurgery@> Like, you just plugged in the enet cable, or also power?
08:13 PM lcnc-relay: <skunkworks8841@> 5v usb power - and ethernet
08:13 PM Tom_L: you need power on
08:13 PM lcnc-relay: <imagesurgery@> Yeah, maybe I talk to mesa, but I will try a 5V source instead first.
08:13 PM lcnc-relay: <skunkworks8841@> *5v from the usb port - powering the mesa card.
08:13 PM Tom_L: i don't have that card either
08:13 PM Tom_L: but do have several ethernet cards
08:14 PM lcnc-relay: <skunkworks8841@> you don't have 5 volts - or are you powering it from the field?
08:14 PM Tom_L: i've used usb 5v power many times
08:14 PM lcnc-relay: <skunkworks8841@> (I don't know how that is setup_
08:14 PM lcnc-relay: <imagesurgery@> Oh… was jumping field in to VIN needed? I have read things that looked confusing regarding power.
08:14 PM lcnc-relay: <skunkworks8841@> same - all the time for testing
08:15 PM lcnc-relay: <imagesurgery@> I am powering via a 24v wall wart in field power, with all the jumpers at defaults which should flow to io and the base card, I believe.
08:15 PM Tom_L: field voltage will vary
08:15 PM Tom_L: is there a jumper for field power source?
08:16 PM lcnc-relay: <imagesurgery@> W1; default and currently L, COM (R is SEP)
08:16 PM lcnc-relay: <imagesurgery@> This is what I believe feeds VIN
08:17 PM lcnc-relay: <imagesurgery@> And VIN should feed the onboard regulator for the 5V supply, I thought. But I will check the jumpers then try a separate 5V supply.
08:20 PM Tom_L: read P17 on field power
08:20 PM Tom_L: VIN power must be present for
08:20 PM Tom_L: the 7I76EU field I/O to be detected and operate.
08:21 PM Tom_L: doesn't say about the ethernet
08:21 PM lcnc-relay: <skunkworks8841@> yah - I think you need 5v for the logic fpga side.
08:21 PM Tom_L: not positive but i was thinking some boards need field power to work
08:22 PM lcnc-relay: <skunkworks8841@> I think they work - just missing a lot of pins..
08:22 PM Tom_L: right
08:22 PM lcnc-relay: <skunkworks8841@> but I could be wrong
08:22 PM Tom_L: you?
08:22 PM Tom_L: never.!
08:22 PM lcnc-relay: <skunkworks8841@> it is late..
08:22 PM lcnc-relay: <skunkworks8841@> drove the 42 to recycling again today. first time since the fall. Ran great.
08:23 PM Tom_L: get any looks?
08:23 PM lcnc-relay: <skunkworks8841@> sully had a blast. That thing is loud in the cab.. can't hardly talk.
08:23 PM lcnc-relay: <skunkworks8841@> a few - lots of waves
08:23 PM Tom_L: fun times
08:23 PM lcnc-relay: <imagesurgery@> Manual P2, VIN power source and Logic Section Power: I read these and understood that the default jumper positions flow power from field to VIN and on to 5V reg and on board power. This is desirable and matches the defaults.
08:23 PM lcnc-relay: <skunkworks8841@> the dump works and everything
08:24 PM lcnc-relay: <imagesurgery@> I will power up differently and see what happens.
08:24 PM Tom_L: i think logic power and field power are separate
08:25 PM Tom_L: i also could be wrong
08:25 PM lcnc-relay: <skunkworks8841@> the guy at recycling had seen it parked.. (I guess he lives down the road) but never seen it actually moving
08:25 PM lcnc-relay: <imagesurgery@> Tom_L: Jumper W1 makes me think that is the case if W1 is R.
08:25 PM Tom_L: The 7I76EU can get its 5V Ethernet, encoder, step/dir and serial interface power
08:25 PM Tom_L: from connector P5 or the on card logic power regulator can be used with unregulated DC
08:25 PM Tom_L: power supplied to TB3.
08:26 PM lcnc-relay: <imagesurgery@> Last line…common for all power
08:26 PM lcnc-relay: <imagesurgery@> oh, maybe the psu but not the connections?
08:27 PM lcnc-relay: <imagesurgery@> HA! That's it.
08:27 PM Tom_L: cool
08:27 PM lcnc-relay: <imagesurgery@> Or at least I am pretty sure.
08:28 PM lcnc-relay: <skunkworks8841@> Yay - I don't know what just happened.
08:28 PM Tom_L: well go find out!
08:28 PM Tom_L: aparently field power can be jumpered but still needs supplied to a pin
08:28 PM lcnc-relay: <imagesurgery@> Just looked at the board more closely and the power LEDs near the rj45 are indeed on my board too, just very far away. And they've not lit up, so likely that bit of the board has never had power.
08:28 PM Tom_L: is what i get from it
08:29 PM lcnc-relay: <skunkworks8841@> ah
08:29 PM Tom_L: peter tries to make the boards flexible
08:29 PM lcnc-relay: <skunkworks8841@> right
08:29 PM lcnc-relay: <skunkworks8841@> like linuxcnc lol
08:29 PM lcnc-relay: <imagesurgery@> So I'll jump via wires from TB1 to TB3, that should be in line with operating the reg.
08:29 PM Tom_L: tp looks interesting
08:30 PM lcnc-relay: <skunkworks8841@> right? Good read..
08:30 PM Tom_L: unless the onboard regulator needs more than 5v to power it
08:30 PM lcnc-relay: <skunkworks8841@> I remember them playing with it - but it seems pretty close now - like workable
08:30 PM lcnc-relay: <imagesurgery@> It gets 24v
08:30 PM Tom_L: ok
08:30 PM lcnc-relay: <imagesurgery@> and requires 8-28
08:30 PM Tom_L: jup
08:34 PM Tom_L: the suspence is killing me
08:35 PM lcnc-relay: <imagesurgery@> hehe I'm working on it!
08:35 PM Tom_L: i know
08:35 PM lcnc-relay: <imagesurgery@> Will report. Enjoy a cool beverage
08:36 PM lcnc-relay: <imagesurgery@> And reading very, very closely to make sure I don't 24V the wrong bits.
08:38 PM Tom_L: good idea
08:39 PM Tom_L: hah i never set ethernet up on the dev pc since i loaded the RTAI kernel
08:39 PM Tom_L: kinda makes sense because ethernet requires preempt-rt
08:51 PM xxcoder: oh boy. storm is starting to arrive
08:51 PM Tom_L: did you piss mother nature off?
08:53 PM lcnc-relay: <imagesurgery@> "sudo cat /sys/class/net/eno1/carrier" returns 1 !
08:53 PM lcnc-relay: <imagesurgery@> Lights and stuff!
08:54 PM Tom_L: have you tried mesaflash?
08:54 PM lcnc-relay: <imagesurgery@> But, I still can't get results from mesaflash:
08:54 PM lcnc-relay: "mesaflash --addr 10.10.10.10 --device=ETHER --readhmid"
08:54 PM lcnc-relay: No ETHER board found```
08:55 PM Tom_L: not that it matters, what mesaflash version?
08:56 PM Tom_L: 3.5.11 is the latest
08:56 PM lcnc-relay: <imagesurgery@> 3.4.6
08:56 PM lcnc-relay: <imagesurgery@> wow, that's wayyy old
08:56 PM lcnc-relay: <big_kevin420@> i mean, it looks like it does get results
08:56 PM Tom_L: download it from linuxCNC/mesaflash git repo
08:56 PM Tom_L: then make install
08:56 PM lcnc-relay: <big_kevin420@> the fact that it knows its a 7i76eu
08:57 PM Tom_L: sudo make install
08:57 PM lcnc-relay: <big_kevin420@> man the 7i76 is a good board
08:57 PM lcnc-relay: <imagesurgery@> It does see the board, the version of mesaflash is too old. This sounds really, really good to me and thanks y'all @Tom_L, big_kevin420@ 'n skunkworks8841@ !
08:58 PM Tom_L: for a list: mesaflash --device anyboard and it will list the possibilities
08:58 PM lcnc-relay: <imagesurgery@> I can't wait… going back to working on it. I'll let you know when I find another problem or I make a chip.
08:59 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/temp/smile.jpg
08:59 PM lcnc-relay: <imagesurgery@> Anyway, for those using search, it turns out that yes, the 7i76EU takes one 8-28V PSU to power it, but it needs to be connected to TB1 _and TB3_ or it won't work.
09:00 PM Tom_L: https://github.com/linuxCNC/mesaflash
09:00 PM Tom_L: may be newer than i said
09:00 PM Tom_L: he bumped the version yesterday
09:02 PM Tom_L: 3.5.13
09:02 PM Tom_L: just built it
09:04 PM xxcoder: Tom_L: nah rare thunderstorm/toroados
09:04 PM xxcoder: big hail is a possibility too
09:04 PM Tom_L: you don't get many tornados there do you?
09:04 PM xxcoder: nope
09:04 PM xxcoder: it says "small chance" but yeah its rare to even go that high
09:04 PM lcnc-relay: <imagesurgery@> Tom_L: painless. Done in 1.
09:05 PM lcnc-relay: <imagesurgery@> I HAVE PINS!!! Thanks everyone!
09:05 PM Tom_L: yippee!
09:06 PM Tom_L: you are now the new resident guru on 7i76EU
09:06 PM lcnc-relay: <imagesurgery@> Someday I might be able to help a person out.
09:06 PM lcnc-relay: <imagesurgery@> I still have a commit I need to do over on klipper… I am not a coder but I am getting more expert every day.
09:06 PM Tom_L: i knew some require field power but don't know which ones
09:06 PM xxcoder: 🎉
09:07 PM xxcoder: way to go
09:09 PM lcnc-relay: <imagesurgery@> https://imgur.com/a/5VJQ4d9 Here's the working wiring
09:11 PM lcnc-relay: <imagesurgery@> * https://imgur.com/a/5VJQ4d9.jpeg
09:12 PM Tom_L: both worked
09:12 PM lcnc-relay: <imagesurgery@> neither expanded though
09:32 PM lcnc-relay: <skunkworks8841@> Yay!
10:07 PM Tom_L: skunkworks, do you know if that eu board is the new fpga?
10:07 PM Tom_L: that might explain the mesaflash update required
