01:33 AM Deejay: moin
02:54 AM Loetmichel: *giggle* Coworker just came by: "Damn HP. New monitor menue key PCB. Four wires, six buttons and a led, all embedded in plastic. How do they do it? Mini Processor??" I looked at it: "nah, that would be expensive. They just paralleled three buttons each on two of the lines with different resitors so they can discern via measuring the resistance on the other end." $me measueres a bit and
02:54 AM Loetmichel: whips up a quick schematics. "See? Its easy. if you have seen this a few times." Cant beat dirt cheap and lazy engineeers :)
09:05 AM norias: hi
09:12 AM Tom_L: hi
09:13 AM norias: how are you?
09:13 AM Tom_L: good
10:24 AM roycroft: i installed version 0.9 of qelectrotech a short while ago - it's a development version - but it actually runs on my macs without crashing
10:24 AM roycroft: so perhaps there is hope that i can actually learn and use it
10:27 AM satiowadahc[m]: I enjoy source code comments... from motion.h... (full message at https://libera.ems.host/_matrix/media/r0/download/libera.chat/f7d296af2d38ca2862c7022cbaf3012da71bcbd2)
11:28 AM -!- #linuxcnc mode set to +v by ChanServ
12:02 PM Stevieg: Hi everyone, I am revisiting LinuxCNC after a long absence, re kindling my interest in CNC.
12:02 PM * Loetmichel is getting old. Just listening to https://www.youtube.com/watch?v=vmDDOFXSgAs and i think its absolutely genius. Even though i was not on this world for 10 years on this world when it was written ;)
12:09 PM Stevieg: Could someone please clarify if mesaflash works with the 7i43 via usb? (I understand LinuxCNC is not geared towards USB) but I just want to play around at least initially with programming the 7i43 via Linux as opposed to using the dos / windows supplied software (sc7i43w / sc7i43p, SCM7i43w/p, eppiopr8 / usbiopr8) The source `messaflash` appears to
12:09 PM Stevieg: have reference to USB and it sees the the yi43 /dev/ttyusb0 but will not program it.

12:11 PM Stevieg: Sorry for the dupe I was editing a mistake.... so used to slack these days ;-)
12:18 PM FinboySlick: Loetmichel: Felt the same way when I discovered "The Ventures" https://www.youtube.com/watch?v=XjiOtouyBOg
12:19 PM FinboySlick: They're the most unknown famous band ever.
12:20 PM roycroft: hi folks
12:21 PM roycroft: i think this is the case, but just to be totally clear: can linuxcnc use the i/o pins on a rpi for general i/o?
12:21 PM roycroft: i would not be doing any motion control stuff with them
12:23 PM Loetmichel: FinboySlick: amazing drummers. Bu yeah, wipeot isnt bad either
12:27 PM Stevieg: FinboySlick: Love the garage band sound. Was switched on to by a work pal from Tacoma, when visiting Seattle for work from UK. Specifically `The Fabulous Wailers` and `The Sonics` :-)
12:28 PM roycroft: the ventures are a surf band
12:28 PM roycroft: and they were pretty well known in their heyday
12:31 PM Stevieg: Yeah you are right, I just heard a bit of the tune above and noticed they was from Tacoma so wrongly assumed. But good vibe... when music is good its good! :-)
12:35 PM roycroft: https://www.youtube.com/watch?v=AoryyF5tPDg
12:36 PM roycroft: there's a great garage band from the puget sound region
12:36 PM roycroft: i used to go see them when i lived in bellingham
12:36 PM roycroft: they were funny and entertaining
12:37 PM Stevieg: Ha the garage bands I was switched onto were from the 60's ;-)
12:38 PM roycroft: well they were big in the '80s as well
12:38 PM roycroft: they kind of morphed into the grunge sound
12:38 PM FinboySlick: Stevieg: They made a bunch of songs everybody knows. The Hawaii 5-O theme song, this is one of my favourites https://www.youtube.com/watch?v=iuU3JUs5yBI
12:41 PM Stevieg: Oh yeah now that one.
12:43 PM Stevieg: Here's a mellow tune I love, `It's You Alone` 1965: https://www.youtube.com/watch?v=a_2WCfJH4dM&ab_channel=BrianLinds
12:48 PM Stevieg: Last time I was playing with CNC stuff this was called EMC and I think I was using v2.0.
12:48 PM Stevieg: Good to see a lot of the original guys from back then are still involved.
12:51 PM Stevieg: Remember spending a quite a few hours in IRC chatting with Andy, Chris, Alex, jepler and seb if I remember correctly.
12:52 PM pcw-home: Stevieg Mesaflash used to work with USB but likely has not been tested with USB in years
12:55 PM pcw-home: you would need 1. 7I43 jumpered for USB, 2. sudo mesaflash --device 7I43 --addr /dev/[USB_serial_device] etc
12:56 PM roycroft: does anyone have a good understanding of how to parse chinese english?
12:56 PM roycroft: i'm specfically trying to understand what this really means: "Note: Generally, it will be shipped randomly."
12:58 PM Stevieg: Thanks pcw-home good to know before I spend too much time. I am getting a number of errors when attempting to program. `ERROR: Board 7I43 doesn't support FPGA resetting.` . I'll plug away at it. Is there an alternative that now employed?
01:19 PM pcw-home: That's true, the 7I43 does not support resetting but that should not matter
01:20 PM Stevieg: I also got the message it does not support flashing.
01:23 PM pcw-home: does a read command work?
01:24 PM Stevieg: I should state I am running in a vbox vm with usb pass-through but that shouldn't cause a problem since I can see ttyUSB0. Indeed if I flash it with hostmot2 using the windows tools, I can see the pin assignment `mesaflash --device 7i43 --addr /dev/ttyUSB0 --serial --readhmid --verbose
01:24 PM Stevieg: `
01:26 PM Stevieg: So, mesaflash can read an already programmed 7i43 with hostmot2 `./SC7I43W.EXE ..\..\CONFIGS\HOSTMOT2\USBHM2\SVST4_4B.BIT com1`
01:27 PM Stevieg: But can't seem to program it.
01:44 PM Tom_L: Stevieg, do you have a parallel port to use on it?
01:44 PM Tom_L: that would work
01:44 PM Tom_L: i used to have a 7i43
01:52 PM pcw-home: Yeah, the EPP programming should work but maybe not, LinuxCNC always loaded the firmware to the 7I43 FPGA, and never used the flash
01:52 PM Stevieg: Tom_L I do on the old computer that's still in storage and it did work via para when I was playing with it years back, but am looking for a way via usb under linux. For playing with.
01:53 PM pcw-home: does --program work?
01:53 PM pcw-home: (bypassing the flash)
01:54 PM Stevieg: Yeah thats correct LinuxCNC did the handshake and loading via EPP back in the day. Just thought mesaflash looked interesting for my needs. The source code has reference and aludes to USB for 7i43.
01:54 PM pcw-home: maybe it never supported writing the flash, just programming the FPGA
01:55 PM Stevieg: (bypassing the flash) Nope get the reset error I posted above when using --program and get a flash not supported (or similar) when employing --write
01:56 PM pcw-home: the reset error should be harmless
01:57 PM Stevieg: Thankfully we do have access to the dos / win pascal source for both flash and program, so I may play at coding something up.
02:00 PM Stevieg: "the reset error should be harmless" thanks for heads up, though the 7i43 still remains un-programmed, the `done` led stays on. While employing the dos / win mesa progs the `done` leds become extinguished on successful program.
02:01 PM pcw-home: Except for low level hardware I/O most of the windows pascal stuff will work on unix/fpc with a bit of fudging
02:03 PM Stevieg: Thanks for info, was considering knocking up something in Go, not for any other reason than i've been playing with it more recently.
02:03 PM Tom_L: pcw-home, did that one have spi? i can't recall now..
02:03 PM Tom_L: don't think it did
02:04 PM Tom_L: Stevieg, parallel port is probably your best bet
02:04 PM Stevieg: It only has spi fia the FPGA (after programming) Which talks to the eeprom.
02:05 PM Tom_L: i replaced mine with a 7i90 after shorting something on it
02:07 PM Stevieg: That is another option or I think the 7c80 which has spi if I recall correctly. (would like to employ RPI -> FPGA -> Controller -> motor) Was hoping to fudge it with the 7i43 since I already have it and been a little peeved its been collecting dust for so long ;-)
02:09 PM Stevieg: Ignore my last message re 7c80, I also meant 7i90. https://eusurplus.com/index.php?route=product/category&path=59_62_72
02:10 PM Tom_L: i've tested 7i80 on the rpi ethernet & spi, 7i92 ethernet
02:10 PM Tom_L: you still need a ribbon to connect spi on the rpi
02:10 PM Stevieg: How did it perform in spi mode?
02:12 PM Tom_L: fine as far as i can tell
02:12 PM Tom_L: bench test only, no hardware
02:14 PM Stevieg: Thanks Tom_L, out of curiosity what kind of setups are in vogue these days? From my limited reading LinuxCNC is still very much still following the parport communication route.
02:15 PM satiowadahc[m]: In this corner of the world we bounce between mesa ethernet cards or linuxcnc-ethercat with beckhoff modules
02:17 PM Tom_L: ethernet works good
02:17 PM Tom_L: works on the rpi4
02:18 PM Tom_L: https://www.youtube.com/watch?v=g0OLIth_cOI
02:20 PM Tom_L: mesa has parport, spi, ethernet, pci, pcie
02:22 PM CaptHindsight[m]: trying to understand what this really means: "Note: Generally, it will be shipped randomly." The same applies to the quality of what is shipped.
02:22 PM Tom_L: you get what you get from whatever carrier we decide to use
02:23 PM CaptHindsight[m]: in short, nothing is regular
02:23 PM Tom_L: or we might ship it to your neighbor
02:23 PM CaptHindsight[m]: Vegas Rules, feeling lucky?
02:24 PM Tom_L: not that lucky
02:25 PM Stevieg: Tom_L, satiowadahc[m] thanks for info regarding ethernet route, will take a look into those cards, looks interesting.
02:25 PM Tom_L: it does require preempt-rt
02:25 PM Tom_L: not RTAI
02:25 PM Tom_L: if that matters
02:26 PM Stevieg: (y)
02:27 PM Tom_L: there is a buster distro for the rpi4 though
02:28 PM Tom_L: http://buildbot.linuxcnc.org/dists/buster/2.8-rtpreempt/binary-armhf/
02:29 PM Tom_L: and the rpi .iso is here http://linuxcnc.org/downloads/
02:29 PM Tom_L: it's just an older release of linuxcnc on the .iso
02:29 PM Tom_L: but you can update it
02:30 PM satiowadahc[m]: did have issues with qt based distros on the pi, but removing graphic preview and offset dialogue fixed it
02:32 PM CaptHindsight[m]: why come the Gentoo devs get images that work better on the Rpi's than Raspbian and Armbian?
02:33 PM Tom_L: just cause
02:33 PM CaptHindsight[m]: uh huh
03:09 PM Stevieg: Thanks for the above links chaps.
03:22 PM satiowadahc[m]: https://speedcrunch.org/ -> neat little tool
03:55 PM roycroft: my hp 11c works fine for me :)
03:55 PM roycroft: that speedcrush tool has an = sign
03:55 PM roycroft: so it's inefficient
03:56 PM satiowadahc[m]: Sometimes can't beat the classics
03:57 PM satiowadahc[m]: however I tend to have my hands on a keyboard more than a calculator
03:59 PM roycroft: dc(1) - an arbitrary precision calculator
04:00 PM roycroft: i actually do have an rpn calculator on my iphone
04:00 PM roycroft: i just don't do very well with calculators that are not rpn
04:00 PM roycroft: they frustrate me
04:00 PM roycroft: for many folks the opposite is true
04:01 PM satiowadahc[m]: I also appreciate the ability of 1.1341 inch -> milli meter
04:01 PM roycroft: my 11c does not do that conversion as a built-in function
04:01 PM roycroft: my 32sii does though
04:06 PM satiowadahc[m]: The bitwise table is a nice perk to.
04:06 PM satiowadahc[m]: I've seen many bitwise tables on a calc but this is one of the nicer ones
04:07 PM * satiowadahc[m] uploaded an image: (23KiB) < https://libera.ems.host/_matrix/media/r0/download/matrix.org/QmKeoKDJsOdeXXlzmYXtfATZ/image.png >
04:09 PM roycroft: https://hpmuseum.org/hp16.htm
04:09 PM roycroft: i still lust after one of those
04:09 PM roycroft: but they go for $200+ in crappy condition
04:09 PM roycroft: hard to justify
04:10 PM roycroft: they do binary, octal, hexadecimal math trivially
04:10 PM CaptHindsight[m]: extra points for programming a robot arm to perform all the calculations on an abacus
04:11 PM CaptHindsight[m]: it's like they have a computer or somthin inside
04:11 PM unterhaus: I have an hp41 and two other more recent hp calculators, but I have no idea where they are right now
04:11 PM XXCoder: make an AI, teach it to do calculaions by handwriting equations
04:12 PM CaptHindsight[m]: I use my PC when at a desk, phone when mobile and sometimes a calc when dirty at a machine
04:13 PM CaptHindsight[m]: since it's AI just ask it, why write is the AI dea.... ah nevermind
04:13 PM XXCoder: because why not? write such an advanced thing just to do simple math lol
04:15 PM CaptHindsight[m]: do numbers lie?
04:16 PM solarwind: roycroft did you get a chance to try out your epson lw-px700? It looks good, I'm thinking of getting it for the same reason
04:17 PM solarwind: CaptHindsight[m] my friend has an account with weg and it turns out they make alternators for generators: https://www.weg.net/catalog/weg/US/en/Generation%2CTransmission-and-Distribution/Generators/Alternators-for-Generator-Sets/c/GLOBAL_GENSET
04:17 PM CaptHindsight[m]: solarwind: did you find a suitable generator?
04:17 PM CaptHindsight[m]: I'm supposed to ask before you answer
04:17 PM solarwind: hmm, yes, that is generally how it works
04:18 PM unterhaus: I think the stupid barcode reader for the hp41 is worth more than the calculator
04:18 PM solarwind: Their pricing is quite reasonable for the power
04:18 PM unterhaus: but I want one of the video adapters
04:18 PM roycroft: i did, solarwind
04:18 PM roycroft: and it works brilliantly
04:18 PM solarwind: roycroft thanks, looks like I'll get one as well
04:18 PM roycroft: in fact, i just ordered some overwrap labels for to see how they work
04:19 PM roycroft: roycroft.us.EpsonLabels.jpeg
04:19 PM roycroft: roycroft.us.22ga.jpeg
04:19 PM solarwind: That is excellent
04:19 PM roycroft: the upper two wires in the first picture are 18ga, the middle 14ga, and the lower two 12ga
04:19 PM solarwind: Does it require special heat shrink tubing, or does it print on any generic ones?
04:20 PM roycroft: and ack
04:20 PM roycroft: roycroft.us/22ga.jpeg
04:20 PM roycroft: that one is what it says it is
04:20 PM roycroft: special cartridges from epson
04:20 PM roycroft: and they're pricey, but worth it i think
04:20 PM roycroft: $20-$35 per cartridge, depending on width
04:20 PM roycroft: they're 96" long
04:21 PM solarwind: That's not bad, that's a lot of heat shrink for label use
04:21 PM roycroft: however, as i've said several times, the epsons have a feature that no other printers do that i've found
04:21 PM roycroft: they rewind the label stock after cutting, so you can have really small margins
04:21 PM roycroft: those pictures i linked to are labels straight from the machine - no trimming
04:22 PM roycroft: i have a bunch of brother p-touch label printers, and considered a brother that can take shrink tubing, but with 2" of wasted tubing for every one printed, they are ultra expensive to operate
04:22 PM roycroft: and i looked into the epson "lifetime guarantee" further to see what it covers
04:23 PM roycroft: it said "if it fails, we replace it. if you break it, we replace it."
04:23 PM solarwind: good to know, thanks
04:23 PM roycroft: i am thinking that epson have decided to push the other players out of this market
04:24 PM roycroft: i was mentioning this to jt-shop yesterday
04:24 PM roycroft: if you don't need a hand-held unit, look at their desktop printers
04:24 PM roycroft: those can take bulk tubing/lables, which are 30% less expensive than buying the cartridges
04:27 PM roycroft: the half cut feature is also unique to them, i believe
04:28 PM roycroft: if you need to print a series of labels, you can print them all in one go, with half-cut turned on, and the printer will churn out a single long strip of labels that you can pull apart as needed
04:28 PM solarwind: The brother P900 has the same capability
04:28 PM roycroft: oh, i did not notice that
04:28 PM roycroft: you still get to waste 50+ percent of your label stock with the brothers, though
04:28 PM roycroft: and i'm not dissing brother here
04:29 PM solarwind: Yes there is waste, but they improved it quite a bit in the P900
04:29 PM roycroft: i have a half dozen p-touch labelers, and i like them and intend to keep them
04:29 PM roycroft: they never die for some reason
04:29 PM roycroft: they just become unsupported with the brother software
04:29 PM roycroft: so when i can't use the brother software on one, i get a new one, and park the old one somewhere else until it dies
04:30 PM roycroft: but they don't die, so i have a bunch of them
04:31 PM JT-Shop: epson called me after I placed my order and wanted to know if I wanted some free samples of other labels
04:31 PM roycroft: nice
04:32 PM roycroft: they seem to like to give things away
04:34 PM XXCoder: anvil floating in a liquid
04:34 PM XXCoder: https://youtu.be/f5U63IGmy6Q
04:35 PM roycroft: i just ordered an indicator light tower for my cnc router
04:35 PM roycroft: it was really hard finding one with all the features i need
04:35 PM roycroft: well, not hard
04:35 PM roycroft: but hard to find one that is affordable with the features i need
04:35 PM roycroft: i wanted to spend $50, not $600
04:36 PM satiowadahc[m]: I finally found one that doesn't look like a stack of pucks... I dislike most of them
04:36 PM roycroft: i dislike most of them as well
04:37 PM roycroft: and i'm not thrilled with the look of the one i bought
04:37 PM roycroft: but it was $52 including shipping
04:37 PM roycroft: so it met the budget requirement
04:38 PM roycroft: https://www.aliexpress.com/item/1005001515376387.html
04:38 PM CaptHindsight[m]: i can make stylish light towers
04:38 PM roycroft: that is what i got
04:38 PM CaptHindsight[m]: pick your style or genera
04:38 PM roycroft: can you make them at a reasonable price?
04:39 PM CaptHindsight[m]: I'd go tiki lamp myself
04:39 PM roycroft: hmm
04:39 PM roycroft: how to program linuxcnc to light a tiki torch
04:39 PM roycroft: that could be interesting
04:39 PM satiowadahc[m]: https://www.digikey.ca/en/products/detail/banner-engineering-corporation/CL50GRYALSPQ/10650757 I just got these
04:40 PM CaptHindsight[m]: reasonable to me or you?
04:40 PM roycroft: to me
04:40 PM roycroft: and i'm a fairly reasonable person, i like to think
04:41 PM roycroft: i just paid $52 for that one to which i liked above
04:41 PM roycroft: i'd pay twice that much for a better quality one
04:41 PM roycroft: but not ten times as much
04:41 PM CaptHindsight[m]: send me a found tiki object from Goodwill and I'll make you a deal
04:42 PM roycroft: and it will be controllable with linuxcnc?
04:42 PM roycroft: i'm actually not sure i can fulfill my end of the deal, though
04:42 PM roycroft: i've been scouring the second-hand stores for tiki objects for years
04:42 PM roycroft: they never sell them
04:42 PM roycroft: they ebay them all when they get such things
04:43 PM CaptHindsight[m]: https://content.instructables.com/ORIG/F5I/AY7T/HS18E4EW/F5IAY7THS18E4EW.jpg sans the shade this could be a roadside diner themed indicator
04:44 PM XXCoder: interesting. turn c clamp into arbor press https://hackaday.com/2021/10/07/c-clamp-becomes-light-duty-arbor-press/
04:44 PM roycroft: i'm just hoping that the tubing that supports the light tower isn't some really weird size
04:44 PM roycroft: like 16.7mm with a 0.94mm thread pitch
04:44 PM roycroft: because i need a longer post
04:46 PM CaptHindsight[m]: https://images.lampsplus.com/is/image/b9gt8/66g46 I was thinking something like this
04:46 PM XXCoder: 3d print it in parts and make it
04:48 PM CaptHindsight[m]: https://c.tenor.com/Uf1KnQqEcewAAAAC/osha.gif
04:50 PM CaptHindsight[m]: those things can print anything
04:53 PM CaptHindsight[m]: the goodwills around here don't take computers
04:54 PM roycroft: one of the goodwills here has a computer/electronics store
04:54 PM XXCoder: isnt there computer recycling centers? there certainly one here
04:54 PM roycroft: st vincent de paul also take computers, but they do not accept crt monitors or tvs
04:54 PM CaptHindsight[m]: i should probably start taking in old computers for reuse
04:56 PM satiowadahc[m]: you might think that
04:56 PM roycroft: i just spoke with the manufacturer of the timing gear pulley i'm considering, and they will do custom bores, but they have a 6-10 week lead time
04:56 PM satiowadahc[m]: I purged not long ago and now I'm looking for old computers at auction sites
04:56 PM roycroft: and it will take several days to even get a quote from them
04:56 PM roycroft: i'm not sure i can wait 6-10 weeks to get the milling machine working again
04:57 PM * roycroft has piles of old computers/network gear to get rid of
04:57 PM roycroft: i could use some extra cash flow right now - i should probably put a few up for sale and see what happens
04:58 PM roycroft: if i can sell 10 cisco gigabit switches for $50 each i'd have more room in my house and my wallet would be nicely plumped up
05:00 PM roycroft: one of our submarines just crashed into something in the south china sea
05:00 PM CaptHindsight[m]: PC's only, no monitors
05:00 PM roycroft: it is a nuclear submarine
05:00 PM CaptHindsight[m]: PC's and decent laptops :)
05:01 PM CaptHindsight[m]: "must pass LCNC latency test or fees will apply"
05:01 PM CaptHindsight[m]: large format working inkjets :)
05:01 PM CaptHindsight[m]: laser printers that only require toner
05:01 PM roycroft: i need to get rid of my e size plotter too
05:02 PM roycroft: i haven't used it in a couple years
05:02 PM roycroft: and it consumes way too much space
05:02 PM CaptHindsight[m]: it varies by county and state
05:03 PM CaptHindsight[m]: server racks
05:03 PM CaptHindsight[m]: a co that moved out recently left their old racks and UPS
05:04 PM CaptHindsight[m]: nobody wanted them due to the batteries
05:04 PM satiowadahc[m]: shocking
05:04 PM CaptHindsight[m]: 200lbs + of lead acid
05:05 PM CaptHindsight[m]: we have mobile scavengers around here, usually a 2 man team in a 20+ year old pickup truck with jury rigged superstructure around the bed
05:06 PM CaptHindsight[m]: https://imgur.com/r/wtf/SbR6Z
05:21 PM Tom_L: i think he could get more on that
05:31 PM Tom_L: i still like that one skunkworks posted about the guy stealing a big tire
05:34 PM JT-Shop: that truck looks more like 30 years old, my truck is 20 years old and don't look that bad
05:34 PM Tom_L: i dare say you probably take better care of yours
05:35 PM Tom_L: JT-Shop, is your honda built in the US?
05:36 PM Tom_L: the one they're building
05:37 PM Tom_L: aparently the ports are all backed up with ships waiting to unload
05:37 PM Tom_L: might be a while
05:37 PM JT-Shop: Alabama
05:37 PM Tom_L: that may not be as bad

05:38 PM Tom_L: we pass by a big Toyota factory every time we go to Ga
06:02 PM circles: anyone know how to set up a 7i92? Replacing a 5i25 as part of a PC upgrade. Ethernet works for internet, but when switched to the 7i92 i get nothing.
06:04 PM Tom_L: what ip is it set for?
06:05 PM Tom_L: and are you using a dedicated ethernet port?
06:05 PM circles: factory condition, so 192.168.1.121 i believe.
06:05 PM circles: yes, there's only one on this pc
06:05 PM Tom_L: i would suggest you set it for the alternate ip 10.10.10.10 and set up a static ip on your pc in that range
06:05 PM Tom_L: it's a jumper on the board
06:06 PM circles: ok. static ip for the pc?
06:06 PM Tom_L: urd
06:06 PM Tom_L: yes
06:06 PM JT-Shop: yeah set static ip for pc at 10.10.10.11 and jumper the 7i92 for 10.10.10.10
06:07 PM Tom_L: https://gnipsel.com/linuxcnc/uspace/debian9-eth.html
06:07 PM Tom_L: might help a bit
06:07 PM JT-Shop: well there you go
06:08 PM Tom_L: https://www.kwch.com/2021/10/07/many-wichita-without-water-due-water-main-break/
06:08 PM Tom_L: small leak causes us to boil water
06:08 PM circles: ok jumpered
06:09 PM Tom_L: follow the directions for setting up a static ip unless you already know how
06:10 PM Tom_L: also, pc to card, no router
06:11 PM roycroft: does the mesa board require a crossover ethernet cable?
06:11 PM Tom_L: no
06:11 PM roycroft: cool
06:11 PM Tom_L: i'm sure peter was wise enough to take care of that for us
06:11 PM roycroft: is it hard wired that way, or is it auto-sensing?
06:11 PM Tom_L: you'd have to ask him
06:11 PM roycroft: i shall, next time i see him
06:11 PM roycroft: it doesn't matter, but i'm curious
06:12 PM Tom_L: pcw-home??
06:12 PM roycroft: which is a character trait that has gotten me in a lot of trouble before, and still does occasionally
06:12 PM roycroft: it's not worth beetlejuicing him for that
06:12 PM roycroft: i'll just ask the next time i see him active
06:13 PM circles: ok static ip set, no router being used, not a crossover cable
06:13 PM roycroft: and you're feeding 5v to the mesa board, i presume?
06:13 PM JT-Shop: roycroft, just a normal lan cable
06:14 PM circles: yes, from a 5v meanwell
06:14 PM JT-Shop: circles, ping the board
06:14 PM circles: pinging
06:14 PM JT-Shop: you can send 5v from the 7i92 to the daughter card
06:15 PM JT-Shop: https://gnipsel.com/mesa/7i92/index.html
06:15 PM circles: that's a jumper change too right? right now I have the meanwell powering both.
06:15 PM circles: no response from ping
06:15 PM JT-Shop: yeah you can set a jumper on the 7i92 to power the daughter card but the field io must have it's own power
06:16 PM circles: the user leds on the 7i92 are off, so that's different.
06:16 PM JT-Shop: chow time here
06:16 PM circles: yeah i've got the field powered from a different PSU.
06:16 PM circles: thanks for your help. i'll keep tinkering.
08:52 PM circles: alright back at it. something must be wrong with my ethernet config, as it doesn't want to take the IP address I'm giving it (10.10.10.11)
08:53 PM circles: 2: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether d4:c9:ef:d5:47:65 brd ff:ff:ff:ff:ff:ff
08:58 PM circles: Ooooo boy, rebooting seems to have fixed it, as I can now ping the card.
08:59 PM Tom_L: yay
09:00 PM circles: $ mesaflash --device 7i92 --readhmid results in 'No 7I92 board found' so I'm still missing something.
09:00 PM circles: but yay progress!
09:00 PM Tom_L: you need the ip address
09:01 PM circles: ah, k
09:01 PM circles: probably this: mesaflash --device 7I92 --set ip=10.10.10.10
09:02 PM Tom_L: --addr 10.10.10.10
09:02 PM Tom_L: not set
09:02 PM Tom_L: it's already set
09:03 PM Tom_L: mesaflash --help
09:03 PM circles: ah yeah, this worked: mesaflash --device 7i92 --readhmid --addr 10.10.10.10
09:04 PM circles: and i got a sweet sweet HOSTMOT2 payload. i'm excited we're moving the needle.
09:20 PM XXCoder: click this video if you dare, that guy is really really dumb and is a danger to himself and others. https://www.youtube.com/watch?v=Lti_zl3MnT4
09:36 PM Tom_L: i've seen plenty of dumb...
09:40 PM XXCoder: that video is distilled dumb
09:59 PM roycroft: i don't want to have to put you on my list of people who's links i never go to, xxdcoder ... :)
10:05 PM XXCoder: roy yeah thats why I gave link PLENTY of warnings on dumbness lol
10:08 PM roycroft: i'll note that when you go to disclaimerville you really mean it
10:09 PM XXCoder: yep
10:09 PM roycroft: i just put my old timing gear in the 3 jaw and indicated it
10:10 PM roycroft: the chuck is a lot more concentric than i thought
10:10 PM XXCoder: 3 jaw should be pretty good on that
10:10 PM roycroft: it had a 0.002" high spot that was right on one of the jaws
10:11 PM roycroft: and i rotated the part and reindicated twice, and the high spot was always in the same place
10:11 PM roycroft: i can probably shim the other jaws pretty easily to get it down to <0.001"
10:12 PM roycroft: the hub diameter of the old gear must be right at the sweet spot for that chuck
10:13 PM roycroft: and for this application, 0.002" probably would make no difference at all
10:15 PM XXCoder: yeah always comes down to tols
10:15 PM XXCoder: though I wonder if that .002 is actually some burr on one of jaw
10:15 PM XXCoder: or indention
10:16 PM roycroft: the jaws are clean
10:16 PM roycroft: 3 jaw scrolls are notoriously not, though
10:17 PM roycroft: and the chuck is further off than that at other diameters
10:24 PM XXCoder: ok
