01:50 AM lcnc-relay: <xxcodery> perfect xkcd on eclipses lol
02:03 AM pere: The German translation is just 334 strings away from 100% on <URL: https://hosted.weblate.org/projects/linuxcnc/#languages >. Anyone here able to help bring it up to 100%?

02:40 AM XXCoder: been also looking forward tp PDK plastic
02:40 AM XXCoder: its made from ground up to be recyclable and infinitely so
02:40 AM XXCoder: just melt it with acid, filter it, and reform it. all additives, colorants, other stuff is gone

05:14 AM lcnc-relay: <travis_farmer> Morning 🙂
05:15 AM JT-Cave: morning
06:11 AM lcnc-relay: <travis_farmer> i don't have shipping setup yet on my online store... yet... but i wonder if there is a market for being a Mesa reseller for the East Coast... ?
06:55 AM Centurion_Dan1 is now known as Centurion_Dan
07:23 AM lcnc-relay: <oddname_skane> for future reference ,is it possible to boot up linux with linuxcnc straight into linuxcnc and full screen
07:23 AM lcnc-relay: <oddname_skane> as if it was only linuxcnc on the computer

07:35 AM Tom_L: morning
07:42 AM Centurion_Dan1 is now known as Centurion_Dan
07:44 AM JT-Cave: you sailing?
07:46 AM Tom_L: Yup
07:46 AM Tom_L: Just did a pull
07:46 AM JT-Cave: pull?
07:46 AM Tom_L: Rough sea today
07:46 AM Tom_L: Git pull
07:46 AM JT-Cave: ah
07:47 AM JT-Cave: got your laptop with you?
07:47 AM Tom_L: Phone
07:47 AM Tom_L: sry, can't test with it:)
07:49 AM Tom_L: left around 4pm yesterday
07:49 AM JT-Cave: no problem
07:49 AM * JT-Cave starts his chicken day
07:50 AM Tom_L: went ahead and got wifi
07:50 AM Tom_L: later

09:31 AM Tom_L: 60mph headwind today
09:32 AM JT-Shop: damn
09:32 AM * Tom_L adds a few more rocks in his pocket
09:33 AM Tom_L: out by the pool
09:35 AM JT-Shop: rain here the next 3 days and nights
09:36 AM roycroft: we're supposed to get a break in the weather for a few days
09:36 AM -!- #linuxcnc mode set to +v by ChanServ
09:37 AM roycroft: no more rain until the beginning of next week
09:37 AM Tom_L: Is it rained here a little bit yesterday?But it's clear today
09:37 AM Tom_L: Just real windy
09:53 AM lcnc-relay: <zincboy_ca_on> Yes. Looking up linux kiosk mode will give some hints but it is pretty easy to set it up to auto login and launch LinuxCNC on boot.
10:00 AM lcnc-relay: <oddname_skane> hmm that works for apps too?
10:02 AM lcnc-relay: <oddname_skane> I figured that only worked with terminal and web-browsers for some reason
10:38 AM lcnc-relay: <zincboy_ca_on> You can set anything to run on startup so the only trick is configuring the auto login.
10:49 AM lcnc-relay: <oddname_skane> as a linuxdummy, cron seems like a decent way?
10:50 AM JT-Cave: system > preferences > startup applications
10:50 AM lcnc-relay: <oddname_skane> ah that simple 😄
10:50 AM JT-Cave: auto login is simple too
10:51 AM JT-Cave: https://gnipsel.com/linuxcnc/debian-11-fix.html
11:00 AM lcnc-relay: <perry_j1987> good morning
11:04 AM lcnc-relay: <oddname_skane> thanks, alot of good tips, a linux-dummy appreciates 😄
11:18 AM lcnc-relay: <perry_j1987> so I got this lathe with the mesa 7i96 and gecko g320 servo drives in it. i just added the mesa 7i85 encoder interface and got the encoders plugged into it and jumpers for A, B and GND over to the gecko servo drives.
11:19 AM lcnc-relay: <perry_j1987> i mainly wanted to just be able to home the machine and then back off until it sees a index pulse from the encoder. but what else could i do with this setup? as the gecko g320 will still be handling the closed loop side of things etc
11:27 AM pcw--home: If the G320 is closing the position loop, you need firmware that supports step/dir index
11:28 AM pcw--home: : 7i96s_7i85dsdi.bin
11:35 AM lcnc-relay: <perry_j1987> is that in the folder
11:36 AM lcnc-relay: <perry_j1987> i downloaded the zip off the site for the 7i96.
11:36 AM pcw--home: Yes, it's in the 7I96S zip file
11:36 AM lcnc-relay: <perry_j1987> i dont have the S
11:39 AM pcw--home: Ahh you have a plain 7I96
11:40 AM lcnc-relay: <perry_j1987> ya the non S 7i85 as well
11:41 AM lcnc-relay: <perry_j1987> i believe i flashed it with the 7i96_7i85d.bit from the folder
11:41 AM Connor: Yea, so, what is the difference between the S and Non S versions ?
11:41 AM lcnc-relay: <travis_farmer> Superspeed
11:42 AM lcnc-relay: <perry_j1987> post pandemic and pre pandemic i think isnt it? 😛
11:42 AM lcnc-relay: <perry_j1987> thought there was chip shortage or something that facilitated a bit of redesign for new chip
11:42 AM pcw--home: S has the spindle analog (and a different FPGA)
11:43 AM roycroft: practically speaking, post-supply chain collapse and pre-supply chain collapse
11:44 AM Connor: Is there a 7i96e post c19 ?
11:44 AM roycroft: and the supply chain collapse was an opportunity to improve the product
11:47 AM pcw--home: 7I76EU
11:47 AM Guts92: Who has heard of the SSCNET protocol ?
11:48 AM lcnc-relay: <perry_j1987> so do I need a different firmware than 7i96_7i85d
11:53 AM mrec_: Guts92: I heard about it
11:53 AM mrec_: but the linuxcnc part of it is closed source so I'm not interested in it
11:54 AM Guts92: mrec_ on which system precisely ?
11:54 AM Connor: What's the key FUNCTION difference with 7i76EU? It says Universal output.. the manual still links to the old 7i976E manual.
11:54 AM mrec_: also SSCNET could be implemented in a MESA card not a PCIe card
11:54 AM mrec_: I have Mitsubishi Meldas MDS-B-SVJ2 (I have that one)
11:55 AM mrec_: however one amplifier is defect and the project was stuck for 2 weeks, tomorrow a new amplifier will arrive
11:56 AM pcw--home: Building 7i96_7i85sdid firmware...
11:56 AM Guts92: mrec_ I want to know how this SSCNET protocol works, or see another protocol that works the same way
11:56 AM lcnc-relay: <perry_j1987> ah ty
11:57 AM lcnc-relay: <perry_j1987> what is the naming convention stand for *sdid
11:57 AM mrec_: I found a nice chinese company which tries to supply all the parts which I suspect are damaged in the old amplifier as well.
11:58 AM mrec_: Guts92: without owning a workable setup no chance, the protocol is not documented
11:58 AM pcw--home: SDI is Step Dir Index
11:59 AM mrec_: or at least not documented well enough to make it work and the risk of damage could be high in most cases (since they're built into machinery)
11:59 AM mrec_: pcw--home: a project for you :D implement SSCNET into mesa
12:00 PM Guts92: mrec_ yes I know it is not publicly documented, but I just want to have a similar protocol !
12:01 PM mrec_: Guts92: you can search around the yurtaev website, also check archive.org. In early days he put some more information online (some code)
12:05 PM Guts71: mrec_ Thank you su much!!
12:05 PM Guts71: so*
12:07 PM mrec_: Guts71: do you plan to reimplement the SSCNET protocol?
12:08 PM Guts71: mrec_ no I just want to understand how it works
12:08 PM mrec_: he configured linuxcnc to submit the data every 0.888 milliseconds or so
12:09 PM mrec_: the fpga card will just translate the signal
12:09 PM mrec_: (I guess)
12:09 PM Guts71: ok I didn't know that, valuable information !!!
12:09 PM pcw--home: Connor: 7I76E --> 7I76EU differences are mainly universal outputs, no clamp diodes needed, support for both ENA/DIR and FWD/REV on spindle control
12:10 PM Connor: Ahh.. Okay.
12:10 PM mrec_: Guts71: if you figure out anything interesting please let me know, I'm also working on it
12:11 PM mrec_: tomorrow the new amplifier will arrive, I plan to connect a logic analyzer to the servo wires within the next 1-2 weeks
12:11 PM Connor: I added snubber diodes to my pneumatic solenoids.. Still saw transit spikes of 26.8v in under 10 microseconds. It killed (not once by twice) a IR wireless probe receiver..
12:11 PM Guts71: mrec_ ok Great, I will keep you informed
12:12 PM mrec_: I hope nothing else will be wrong with this Mitsubishi based CNC, it lost all the settings before and finally the amplifier for the Y axis broke which again halted the entire machine
12:12 PM mrec_: the original manufacturer only has a corrupted backup, and they told me they outsourced all the electronics back then
12:12 PM mrec_: the machine is ~20 years old and no one used it for ~4 years
12:14 PM lcnc-relay: <perry_j1987> how hard would it be to find another customer of that machine who has a better copy of the backup??
12:16 PM mrec_: they said back then every customer has a slightly different machine
12:16 PM mrec_: we got a reference copy from another machine, I tried to recover the settings already (but I'm stuck with the defect amplifier) tomorrow the journey will continue
12:16 PM mrec_: I had Z and X move already
12:18 PM lcnc-relay: <perry_j1987> ah
12:19 PM mrec_: so far I think the PLC data in the machine is still correct I made a backup of what was there. The backup from the manufacturer skipped bytes every now and then
12:20 PM mrec_: I would like to remove the old controller and put linuxcnc there (that's why I'm also interested in the SSCNET protocol)
12:21 PM mrec_: and I don't want to use the card at yurtaev.com but a mesa card via ethernet
12:26 PM pcw--home: I guess SSCNET is a reverse engineering project if there's no manufacturers data...
12:33 PM JT-Cave: is that a cloned 5i25?
12:38 PM mrec_: let me guess... I would say yes
12:38 PM mrec_: he'd like to charge 500 EUR for this card
12:38 PM mrec_: http://yurtaev.com/pricelist.html
12:39 PM mrec_: the problem for me is especially the closed source part I don't want to be locked with a particular linuxcnc version
12:40 PM mrec_: 2023.12.27 LinuxCNC 2.9.2nyx44 release
12:42 PM JT-Cave: yup sounds a bit fishy to me
12:42 PM mrec_: also in my Mitsubishi CNC, there are some IO multiplexer/translation boxes inside, I'd like to interface those too
12:43 PM mrec_: that's not part of SSCNET
12:43 PM mrec_: the original meldas 60 controller for sure isn't so bad but LinuxCNC has some better features in other areas
12:44 PM mrec_: and if that controller decides to die, all the electronics need to be replaced (those IO multiplexers, etc) so I'd like to hurry up with interfacing what's there

01:18 PM JT-Shop: nice add a printer gave me the blue screen of death
01:26 PM lcnc-relay: <perry_j1987> good ole windows lol
01:27 PM roycroft: roycroft.us/ReinstallingWindows.mp3
01:27 PM Unterhausen: the forum loads really slowly for me
01:28 PM Unterhausen: nvm temporary
01:30 PM lcnc-relay: <perry_j1987> pcw--home checking on the firmware build. wana make sure i didnt miss a link or something you gave
01:32 PM pcw--home: Its very close to the resource limit so routing has taken hours, I probably need to delete some sserial channels
01:33 PM pcw--home: (I used a 7I96S pinout file, but the 7I96S has a bigger FPGA)
01:34 PM pcw--home: down to ~7000 unrouted from ~32000 but it may fail
01:35 PM pcw--home: if it fails, I'll drop a sserial and try again. its right on the edge of fitting
01:36 PM lcnc-relay: <perry_j1987> ok
01:42 PM mrec_: I think that sscnet card from that russian might be a partial copy but not entirely from mesa, it comes with its own linux driver. Basically just mapping some dma memory and piping the linuxcnc coordinate / etc. data out onto the line
01:57 PM lcnc-relay: <travis_farmer> _wishes he had as much skill and knowledge as pcw--home_
02:09 PM pcw--home: http://freeby.mesanet.com/7i96_7i85sdid.zip
02:09 PM pcw--home: I'm just old and have banged away at stuff for long time...
02:11 PM lcnc-relay: <perry_j1987> got the file transfering to the machine
02:12 PM pcw--home: bbl
02:12 PM lcnc-relay: <perry_j1987> flashed

03:15 PM XXCoder: its pretty good machine, though far from perfect
03:16 PM XXCoder: the second to last link (77 end of url) is model I used to run all time
03:16 PM CaptHindsight: https://www.ebay.com/itm/225638706306 a beast for <$3k
03:18 PM CaptHindsight: https://www.ebay.com/itm/126302083128
03:18 PM XXCoder: you researching them to buy one?
03:19 PM XXCoder: anyway old fadal is quite good, its computer suck though so I would get it only if you plan to gut computer system anbd replace it with modern one with linuxcnc

05:11 PM XXCoder: whew sudden hotter today
05:12 PM XXCoder: had to go out shopping for myself and my nephew

05:13 PM Loetmichel: Phew. Just came home from work. 08:30 to 23:45. Fact: It feels not as easy as 30 years ago... I'm pretty exhausted now.
05:14 PM * roycroft has been burning the candle at both ends for a while now
05:15 PM Loetmichel: especially soldering 0805 and 0402 caps/resistors bent over a stereo microscope for most of that time did things to my back... *ouch*
05:15 PM XXCoder: aw that sucks
05:32 PM Unterhaus_ is now known as Unterhausen
05:32 PM Unterhausen: I feel like I have accomplished something when I solder one thing under a microscope
05:33 PM Unterhausen: good thing I got cataract surgery
05:34 PM Loetmichel: Unterhausen: imagine sitting bent over that for 16 hours: http://www.cyrom.org/palbum/main.php?g2_itemId=18069&g2_imageViewsIndex=1
05:35 PM Loetmichel: and modifying clock circuits with 22p caps that the manufacturer (Sennheiser) botched to the extent that they transmit 900MHz while the clock is only 25Mhz.
05:35 PM Loetmichel: 30* 5 caps. As i said: long day :D
05:38 PM CaptHindsight: https://youtu.be/xs0mP2cOmJs?si=ZOA9hsQYcbgjOGfJ&t=349
05:40 PM Loetmichel: CaptHindsight: thats a mechanical marvel
05:42 PM Loetmichel: i like those paper strip driven instruments/machines. Helped a friend of my mother maintain a dozen or so mechanical looms that worked with the same principle in my youth.
05:44 PM roycroft: weaving looms were the first cnc machines
05:45 PM roycroft: the jacquard predated babbage by over half a century
05:46 PM roycroft: jacquard loom, rather
05:46 PM roycroft: and many of the tartan weavers in scotland still use the same kind of loomk with the same punch cards
05:50 PM Loetmichel: I know. The friend makes those Firefigher/police/services patches though, so the cards are nowadays punched by a CNC punch.
05:50 PM Loetmichel: "Nowadays" as in 30+ years ago
05:51 PM roycroft: one can purchase laser-cut jacquard mill cards now
05:51 PM roycroft: er, jacquard loom cards
05:52 PM Loetmichel: yeah, i cant remember if they were jaquard, but they used thick cardboard cards sewed together to a "zigzag-stack"
05:54 PM roycroft: that sounds like jacquard cards
05:54 PM roycroft: but there may be other machines that use similar ones

06:28 PM lcnc-relay: <skunkworks8841> Speedometer seems to work... But all the other gauges need to be replaced.. Probably need a speedo cable.
06:28 PM lcnc-relay: <skunkworks8841> did you know you can buy GPS analog speedometers?
06:28 PM lcnc-relay: <skunkworks8841> I didn't until I looked.. It is tempting..
06:29 PM lcnc-relay: <skunkworks8841> for 50ish dollars
06:29 PM XXCoder: would be interesting in few applications
06:36 PM Unterhausen: I have wanted to put a camera on my microscope, but it doesn't have a place for it. But there is a cover on the back, I need to check to see if it's hiding a 3rd port
09:24 PM XXCoder: tried and learned how to sharpen and strop knives
09:24 PM XXCoder: it was interesting
