12:00 AM Unterhausen: It was always funny talking to easterners when the snow was bad, they loved it
12:12 AM lcnc-relay: <hilo90mhz> I am trying to get my first EtherCAT drive working, getting some errors..
12:12 AM lcnc-relay: <hilo90mhz> hilo@linuxcnc:~/dev/hal-cia402$ halcmd loadusr -W lcec_conf ethercat-conf.xml
12:12 AM lcnc-relay: <hilo90mhz> <commandline>:0: execv(lcec_conf): No such file or directory
12:12 AM lcnc-relay: <hilo90mhz> <commandline>:0: waitpid failed lcec_conf lcec_conf
12:12 AM lcnc-relay: <hilo90mhz> <commandline>:0: lcec_conf exited without becoming ready
12:12 AM lcnc-relay: <hilo90mhz> following instructions here https://forum.linuxcnc.org/ethercat/45336-ethercat-installation-from-repositories-how-to-step-by-step
12:12 AM roycroft: i have multiple parcels that are "out for delivery"
12:12 AM roycroft: i am not holding my breath
12:12 AM lcnc-relay: <unterhausen> "no such file or directory" seems like it would be a pretty big clue
12:12 AM lcnc-relay: <hilo90mhz> yeah just not sure where or what the lcec_conf file does
12:12 AM Unterhausen: my lee valley order is coming tomorrow, got to start on my skew plane
12:12 AM lcnc-relay: <hilo90mhz> something compiled as part of the ethercat libs seems like
12:12 AM lcnc-relay: <unterhausen> it's not finding ethercat-conf.xml
02:46 PM JT-Cave: cool
03:28 PM CaptHindsight: https://linuxgizmos.com/low-profile-radxa-x2l-sbc-featuring-intel-j4125-and-rp2040-microcontroller/
03:28 PM CaptHindsight: Celeron cpu and rp2040 for $50!

03:37 PM CaptHindsight: https://linuxgizmos.com/rp2040-based-board-featuring-6-high-power-module-slots-with-up-to-15a-continuous-delivery/
03:37 PM JT-Shop: hmm I need a place for a keyboard on the BP
03:37 PM CaptHindsight: great for remora
03:38 PM CaptHindsight: I haven't been keeping up with the new boards that fit LCNC
03:45 PM Tom_L: not sure anyone has lately
03:52 PM XXCoder: no ice here it looks like, but my bro and sis in law is stuck in massive ice
03:52 PM XXCoder: sis in law is stuck at school and bro at home
03:53 PM CaptHindsight: https://arace.tech/products/radxa-x2l $49
03:58 PM JT-Shop: at least it has a RTC
04:05 PM roycroft: it's thawing here
04:06 PM roycroft: but my friends and i postponed our weekly dinner until tomorrow - one of the group is in a wheelchair, and while the roads are drivable, i don't think a wheelchair can handle the slush very well
04:06 PM roycroft: i have several overdue errands to run, and i anticipate being able to do them all this afternoon after work
04:10 PM CaptHindsight: it was below zero here yesterday and I had to watch for people crossing the street in motorized wheel chairs
04:15 PM CaptHindsight: https://imgur.com/gallery/hnD1Bk5 Portland Ice Rink
04:17 PM Tom_L: JT-Shop, do you have a rpi4?
04:18 PM Tom_L: maybe you could test one of those if you want
04:18 PM Tom_L: they seem ok here
04:25 PM JT-Cave: yes, but it needs new cpu fan
04:39 PM Tom_L: oh
04:39 PM Tom_L: i put a heatsink on mine so it's fanless
04:42 PM XXCoder: ow hope that guy was ok
04:53 PM lcnc-relay: <hilo90mhz> Anyone try out this EtherCAT board yet ? https://www.aliexpress.us/item/3256805154534518.html
04:54 PM lcnc-relay: <hilo90mhz> It seems really versatile with the encoder input + analog output - to control an analog VFD spindle and also have speed input for threading operations
05:07 PM JT-Cave: chili is on the simmer
05:07 PM JT-Cave: Tom_L, I think they fixed the overheat issue somehow
05:08 PM JT-Cave: I have a heat sink on mine as well
05:08 PM Tom_L: huh
05:08 PM Tom_L: mine gets warm if i'm compiling or something intensive but not hot
05:08 PM JT-Cave: the early rpi4's had a heat issue
05:08 PM Tom_L: i'm not sure what era mine is but it's fairly old
05:10 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Rpi4/Rpi4_top.jpg
05:11 PM JT-Cave: that's one hell of a heat sink
05:16 PM JT-Cave: a new friend of ours youngest daughter died and I hate going to wakes and funerals but they have become good friends
05:16 PM JT-Cave: the funeral home has a plant a tree tribute thing, going to do that instead of flowers
05:23 PM Tom_L: front and back
05:23 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Rpi4/Rpi4_bottom.jpg
05:24 PM Tom_L: that's sad
05:24 PM lcnc-relay: <hilo90mhz> Those are nice heatsinks! I use them on all my RPI
05:24 PM lcnc-relay: <hilo90mhz> $7 from china or something
05:25 PM Tom_L: doesn't leave room for an IO plug but i'm not using it for that
05:27 PM JT-Cave: yeah she was only 30
05:27 PM JT-Cave: you could machine that hole...
05:28 PM Tom_L: i would lose a screw hole if i did
05:28 PM CaptHindsight: funerals are never fun
05:28 PM JT-Cave: nope
05:28 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Rpi4/Case_top2.jpg
05:28 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Rpi4/Case_top_idc.jpg
05:29 PM Tom_L: already thought about it
05:29 PM Tom_L: c-grid might fit
05:29 PM JT-Cave: oh you can't plug it in?
05:29 PM Tom_L: but then you lose the ribbon
05:29 PM Tom_L: no
05:29 PM JT-Cave: well that sucks but you could drop a few pins and make one fit
05:30 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Rpi4/Case_top3.jpg
05:30 PM Tom_L: hole clearance
05:30 PM Tom_L: i'm not using it but for testing anyway
05:30 PM JT-Cave: I used to have a purple caliper but have no idea what happened to it
05:31 PM JT-Cave: took me over a week to watch skunkworks video
05:31 PM Tom_L: that's farily new but an 'i don't care' pair
05:32 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/calipers/Mitutoyo_case.jpg
05:32 PM Tom_L: that's my good one
05:32 PM Tom_L: and a coupld chinaco ones that could be use for a wrench
05:32 PM JT-Cave: I have a 6" and a 12" mit and 0-6 mics
05:33 PM JT-Cave: 2 minutes till the door to the coop closes
05:33 PM Tom_L: i don't do anything now that requires space station precision
05:34 PM CaptHindsight: the Puritans of CNC
05:35 PM Tom_L: my kid won that exact set at his skills usa competetion
05:36 PM Tom_L: i liked the case so i got one for me
05:36 PM CaptHindsight: was the case made by CNC?
05:36 PM Tom_L: i'm sure
05:37 PM Tom_L: i added the gage block hole
05:37 PM JT-Cave: space station is to the nearest 1/4" I think
05:37 PM JT-Cave: a little roost time rumble going on in the coop...
05:37 PM Tom_L: heh
05:38 PM JT-Cave: I guess the power supply crapped out on the windblows pc down here it won't boot up
05:40 PM Tom_L: https://www.microscopeworld.com/p-2871-digimatic-tool-kit.aspx
05:40 PM JT-Cave: door should be down going to check the call it a day
05:41 PM Tom_L: it's hard to find that set unless you know what you're looking for
05:41 PM JT-Cave: proud of that they are
05:42 PM Tom_L: https://www.microscopeworld.com/p-2871-digimatic-tool-kit.aspx
05:42 PM Tom_L: i just grabbed the first link for the set
05:43 PM Tom_L: his came with a 6" rule but they dropped it from the kit
05:49 PM bjorkintosh: fancy. mine is from harbor freight.
05:49 PM bjorkintosh: it's precisely uhh
05:49 PM bjorkintosh: not meant for precision work.
05:52 PM CaptHindsight: have a pic?
05:54 PM bjorkintosh: https://www.harborfreight.com/hand-tools/measuring-marking/calipers-micrometer/calipers/4-in-digital-caliper-63710.html
05:54 PM bjorkintosh: there's an even cheaper 10 dollar one!
05:54 PM bjorkintosh: haha
05:54 PM CaptHindsight: I think their plastic caliper is ~$10
05:54 PM bjorkintosh: yes.
05:54 PM CaptHindsight: oh $2
05:55 PM CaptHindsight: what a deal :p
05:55 PM bjorkintosh: I got it for quick and dirty measurements.
05:55 PM bjorkintosh: not for machining
05:55 PM CaptHindsight: many shops would be better off with cheap calipers
05:56 PM CaptHindsight: I was at one last week where it was just tossed around and used as a scribe
05:56 PM CaptHindsight: and of course it was a Mitutoyo
05:56 PM bjorkintosh: yeah. cheap calipers, no doubt. you can't do precise work with it any way.
05:57 PM CaptHindsight: https://www.harborfreight.com/hand-tools/measuring-marking/calipers-micrometer/digital-micrometer-63647.html
05:58 PM CaptHindsight: hah Compare to
05:58 PM CaptHindsight: MITUTOYO 293-831-30
05:58 PM CaptHindsight: yeah it's far worse than a real micrometer
05:59 PM Tom_L: bjorkintosh, i have some harbor freight ones too
05:59 PM bjorkintosh: Tom_L, for scribing?
05:59 PM Tom_L: that and double checking drill sizes
06:00 PM Tom_L: roughly
06:00 PM bjorkintosh: quickandirty
06:00 PM bjorkintosh: now that I think about it. quick and dirty should have a tolerance range
06:00 PM Tom_L: CaptHindsight, that mitutoyo is the 'standard' around here for aircraft
06:02 PM Tom_L: i had a pair of fowler for a long time but they finally gave out
06:02 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/calipers/Fowler_case2.jpg
06:02 PM Tom_L: made that case too
06:03 PM Tom_L: those were pretty old
06:05 PM Tom_L: i'd like to find like a 3 or 4" good pair.. not that i really need them
06:09 PM Tom_L: https://www.amazon.com/Mitutoyo-Absolute-Digital-Caliper/dp/B00WNCXSM0
06:09 PM Tom_L: nice for tight spaces
06:23 PM Unterhausen: HF getting pretentious with that $50 micrometer
06:23 PM bjorkintosh: hahah
06:47 PM roycroft: well the arterials are mostly clear now, but the turning lanes are still icy/crunchy
06:47 PM roycroft: side streets are still somewhat icy, but much better than yesterday
07:04 PM -!- #linuxcnc mode set to +v by ChanServ
07:18 PM lcnc-relay: <hilo90mhz> linuxcnc forum seems to be having issues..
07:18 PM lcnc-relay: <hilo90mhz> now its back 🙂
07:19 PM lcnc-relay: <hilo90mhz> now gone..
07:19 PM XXCoder: doh
07:20 PM XXCoder: I trust amazon to send me real mitutoyo as much as I can trust the gas stop sushi
07:20 PM XXCoder: it might be fine, it might not be
07:21 PM lcnc-relay: <hilo90mhz> yeah I was wondering the same thing.. hard to tell, I bought one, works fine
07:21 PM Tom_L: i got mine from a reputable vendor
07:21 PM lcnc-relay: <hilo90mhz> but it might be fake who knows 🤣
07:21 PM XXCoder: same. all of mine is real
07:21 PM XXCoder: think I ordered from MSI? been years
07:22 PM XXCoder: hilo big problem with amazon is in warehouses, they place same product together, from different sources
07:22 PM Tom_L: i know mine are because i registered them
07:22 PM XXCoder: so you could get fakes even from legimate sellers
07:36 PM lcnc-relay: <hilo90mhz> I just remembered probably shouldnt like stuff since the translations.. But yeah I understand how Amazon works.. it is definitely not the best model for certain goods
07:37 PM lcnc-relay: <hilo90mhz> Some other seller can come in and sell fake items on your listing 🤣 and undercut you
07:37 PM lcnc-relay: <hilo90mhz> Its good for cheap crap, or things that cant be faked
07:50 PM roycroft: some amazon marketplace vendors do direct fulfillment
07:50 PM roycroft: if you buy from them, and they are reputable, then you won't have the problem with the amazon warehouse
07:51 PM roycroft: i buy my vfds on amazon, for example, but i buy from huanyang, who do their own fulfillment
07:52 PM roycroft: it's the only way i know of to avoid getting countereit huanyang products
07:53 PM lcnc-relay: <big_kevin420> https://jauriarts.org/_matrix/media/v1/download/jauriarts.org/lVIVrFLbYsDCPIuBKFqjYWoo
07:53 PM lcnc-relay: <big_kevin420> https://jauriarts.org/_matrix/media/v1/download/jauriarts.org/hkjFHGTZgUNoxMiAGpGcysWM
07:53 PM lcnc-relay: <big_kevin420> gonna try 12v tonight on these
07:53 PM lcnc-relay: <big_kevin420> taking bets on weather I have a short or not
07:58 PM * roycroft knows better than to bet on the weather
08:13 PM lcnc-relay: <hilo90mhz> What do those do?
08:14 PM lcnc-relay: <big_kevin420> remora linuxcnc Rpi/ethernet boards
08:14 PM lcnc-relay: <big_kevin420> cheap/easy as possible
08:14 PM XXCoder: just bought a new mouse, finally. directly ordered from logitech. I see no reason not to. 100% fakeproof
08:14 PM lcnc-relay: <big_kevin420> https://jauriarts.org/_matrix/media/v1/download/jauriarts.org/LPHLlROhKskujzhtDBosrrLd
08:14 PM lcnc-relay: <big_kevin420> https://jauriarts.org/_matrix/media/v1/download/jauriarts.org/DACduXmLzNIMqkarmgBhPPDQ
08:14 PM lcnc-relay: <big_kevin420> https://jauriarts.org/_matrix/media/v1/download/jauriarts.org/nLmaTZNskSrnAncjlOxRZeUn
08:15 PM lcnc-relay: <hilo90mhz> nice! oh wow on the raspberry pi itself!
08:15 PM lcnc-relay: <big_kevin420> i bought my mouse from shoppers drug mart
08:15 PM lcnc-relay: <big_kevin420> or ethernet
08:15 PM lcnc-relay: <hilo90mhz> ahh I see
08:15 PM XXCoder: I need good mouse so yeah. I must have turbo wheel lol
08:15 PM lcnc-relay: <hilo90mhz> what protocol would the ethernet use?
08:15 PM lcnc-relay: <hilo90mhz> something custom?
08:16 PM lcnc-relay: <big_kevin420> uhh i guess
08:16 PM lcnc-relay: <hilo90mhz> you're developing the code yourself?
08:17 PM lcnc-relay: <big_kevin420> something i just made for dissemination
08:17 PM lcnc-relay: <big_kevin420> no, i just mash keyboard at other projects
08:17 PM lcnc-relay: <big_kevin420> https://remora-docs.readthedocs.io/en/latest/index.html
08:18 PM lcnc-relay: <hilo90mhz> oh neat! hadnt heard of it before
08:18 PM lcnc-relay: <big_kevin420> but i got tired of soldering protoboards so i just made the thing i want
08:18 PM lcnc-relay: <hilo90mhz> yeah PCBs are great.. I design too
08:18 PM lcnc-relay: <big_kevin420> my first time doing it
08:18 PM lcnc-relay: <hilo90mhz> Kicad?
08:19 PM lcnc-relay: <big_kevin420> no kicad was a steeper learning curve than i expected
08:19 PM lcnc-relay: <big_kevin420> i just went with easyeda
08:21 PM lcnc-relay: <hilo90mhz> ahh cool. Ive been using KICAD for 8 years or something, getting better every year
08:21 PM lcnc-relay: <big_kevin420> i tried it thinking i should just learn it
08:21 PM lcnc-relay: <big_kevin420> but it was way harder
08:22 PM lcnc-relay: <hilo90mhz> next time..
08:22 PM lcnc-relay: <big_kevin420> and i dont know electronics or computers well enough
08:22 PM lcnc-relay: <big_kevin420> and my computer is to old to run uit
08:22 PM lcnc-relay: <big_kevin420> , so i have to use my special computer
08:22 PM lcnc-relay: <hilo90mhz> ahh
08:23 PM lcnc-relay: <hilo90mhz> https://jauriarts.org/_matrix/media/v1/download/jauriarts.org/JGKcBPVhQFUGWctPwFfjoeos
08:23 PM lcnc-relay: <hilo90mhz> I am using EtherCAT, first time moving the servos today
08:24 PM lcnc-relay: <hilo90mhz> just happy they actually work 😅
08:25 PM lcnc-relay: <big_kevin420> beckoff did a sales demo at work the other day, im pretty sold on ethercat for servos
08:25 PM lcnc-relay: <big_kevin420> but damn, ethercat slave controller chips are too damn much money
08:25 PM lcnc-relay: <hilo90mhz> These are Delta $600 for 2KW driver + servo
08:25 PM lcnc-relay: <hilo90mhz> $10-20 for the slave chip looks like
08:26 PM lcnc-relay: <big_kevin420> thats cheaper than the ones i saw, not bad
08:26 PM lcnc-relay: <hilo90mhz> it is a fair bit.. but not much considering the scheme of things in these machines
08:26 PM lcnc-relay: <big_kevin420> yeah, i spare no expense on my fancy machine
08:26 PM lcnc-relay: <big_kevin420> but i like to play with lowest common denomator
08:26 PM lcnc-relay: <hilo90mhz> https://www.aliexpress.us/item/3256803633983833.html?spm=a2g0o.cart.0.0.5d4d38daNbHAW0&mp=1&gatewayAdapt=glo2usa
08:27 PM lcnc-relay: <hilo90mhz> The REMORA project does look cool for that side of things
08:27 PM lcnc-relay: <big_kevin420> thats not too bad
08:27 PM lcnc-relay: <big_kevin420> but yeah i was sold on remora when i saw it can do closed loop
08:30 PM lcnc-relay: <big_kevin420> and if these boards work, i can force them on everyone at the next linuxcnc meetup
08:30 PM lcnc-relay: <hilo90mhz> hahaha nice!
08:30 PM lcnc-relay: <hilo90mhz> can that board to encoder input and +/- 10V analog output?
08:31 PM lcnc-relay: <big_kevin420> encoder yes
08:31 PM lcnc-relay: <big_kevin420> the 10v analog would come from the db25 breakout
08:31 PM lcnc-relay: <big_kevin420> via pwm
08:31 PM lcnc-relay: <hilo90mhz> okay I see
08:40 PM lcnc-relay: <big_kevin420> i just copied the red arduino cnc shield
08:40 PM lcnc-relay: <big_kevin420> for the one
09:33 PM bjorkintosh: https://www.youtube.com/watch?v=XdK-Cr1pe30
11:27 PM * roycroft wonder if big_kevin420 has ever tried the blue arduino
