02:09 AM Deejay: moin
03:00 AM Loetmichel: *pfffrrrrt* 30 min in the workshop and i already seweated thru all my clothes... we REALLY need an A/C or at least an exhaust fan in there with all the machines... also: 2 days not at the company and you come back to a workshop like after a bombing... is it REALLY so hard to NOT let the alu scrap fall to the floor and walk over it but instead cut it small enough for the scrap bin and bring
03:00 AM Loetmichel: it there?
03:44 AM sensille: Loetmichel: do you think this is suited for my 6040? https://www.ebay.de/itm//401824439535
04:06 AM _abc_: reading: https://forum.linuxcnc.org/9-installing-linuxcnc/32941-linuxcnc-on-debian-stretch -- has anyone here got the linuxcnc stretch oriented userland (no rtai) packages going on a devuan host?
04:06 AM _abc_: devuan ascii to be exact
04:25 AM gonzo_: CaptHindsight, appreciate you won't see this for a while
04:25 AM gonzo_: my report of "board at..... not found!" was in the linuxcnc debug popup
04:26 AM gonzo_: I tried both addresses in the rtload
04:26 AM gonzo_: and using ioaddr=0 which picked up the 0xEC00 address
04:27 AM gonzo_: but in all cases, I got the error from linuxcnc that it could not find a boar at that address
04:35 AM gonzo_: I read somewhere that this device is some form of serially addressed IO, with lines used for lpt and com ports.
05:52 AM Loetmichel: sensille: yes, but it needs tons of air
05:52 AM Loetmichel: i would go the route with a "minimalmengen-kühlschmiermittel-düse"
05:53 AM sensille: not for cooling, but for clearing chips
05:53 AM Loetmichel: ah, for plain air its oversized
05:53 AM sensille: my compressor provides 200l/min
05:54 AM sensille: ah, so i need a smaller one?
05:56 AM jthornton: mornnig
06:00 AM sensille: Loetmichel: oh, it seems i actually searched for the wrong thing
06:02 AM sensille: i only want that adjustable tube
06:07 AM sensille: can't find the current search term for it, though
06:16 AM sensille: "cardan joint tube"
06:17 AM jthornton: loc line
06:19 AM sensille: thanks. that seems to be a specific brand, though
06:23 AM jthornton: only brand I've ever seen
06:24 AM XXCoder: jt funny thing happened at work
06:24 AM XXCoder: theres a job that needs broaching done on part
06:24 AM XXCoder: theres 2 types that have broach at opposite sides so theres 2 posts, one on left of fixture and other on right
06:25 AM XXCoder: tool tag says 66-2, handle to right (66-2 is part of part model #)
06:25 AM XXCoder: setup paper says handle to right
06:25 AM XXCoder: program stop says handle to right
06:25 AM XXCoder: left post has red plastic cap on it
06:26 AM XXCoder: guess which way guy went
06:26 AM jthornton: the left
06:26 AM XXCoder: yeah. since broach tool dont share c/l with spindle, it really worked hard on broaching part, and broke
06:26 AM jthornton: ouch
06:27 AM XXCoder: yeah. the broach tool is extremely hard to re-setup.
06:27 AM XXCoder: you need to make 3 or 4 fake parts to test new setup
06:27 AM XXCoder: you need to adjust angle and c/l since again, broach tool dont share c/l with spindle
06:27 AM XXCoder: you need to pray and give stuff to various gods
06:28 AM XXCoder: man last step sucks as you have to clean up setup of blood
06:28 AM jthornton: lol
06:29 AM XXCoder: so end result is 5 ncm parts used up
06:29 AM XXCoder: thats qite a bit of alum metal
06:30 AM jthornton: big part?
06:30 AM XXCoder: not really
06:30 AM XXCoder: its around 6 inches long, 2 inch thick and 3 inch wide
06:31 AM jthornton: pretty big chunk
06:31 AM sensille: Loetmichel: so just one of those $10 "minimalmengenkuehlung" and just use it to blow away chips?
06:31 AM XXCoder: yeah and all that machine time just to make part to be broached test and thrown away.
06:32 AM XXCoder: prep, side a side b
06:32 AM XXCoder: side a is just 15 mnin, side b is 40 min
06:34 AM XXCoder: I guess could be faster if we made "ncm special" part
06:34 AM XXCoder: skip some stuff
06:34 AM XXCoder: it has couple time-expensive features.
06:35 AM XXCoder: it has curved groove with +- .002"
06:35 AM XXCoder: width that is
06:35 AM XXCoder: so it has to cut it out then run over and over to spring cut it as slopes would scrap part
06:35 AM jthornton: round grove
06:35 AM jthornton: ouch
06:35 AM XXCoder: bottom is flat actually. well with some radius
06:36 AM XXCoder: ball endmill to make flat too since its curved down
06:36 AM XXCoder: not down more like curved to flat
06:36 AM XXCoder: hard to explain
06:36 AM XXCoder: skipping that alone would save 20 min maybe
06:37 AM jthornton: sounds complicated
06:38 AM XXCoder: feature itself really isnt too complex.
06:38 AM XXCoder: but its curved in z
06:38 AM XXCoder: and that same feature groove width must be within tol of +- .002"
06:38 AM XXCoder: combination makes for fun and games
06:39 AM jthornton: I bet, glad I don't have to make anything like that
06:39 AM XXCoder: its not worse though
06:39 AM XXCoder: i still remember one part thats quite flat, but flatness must be within .001" across entire thing.
06:40 AM XXCoder: luckly acceptable under 5 pound press
06:40 AM XXCoder: bag of lead pellets thing
06:40 AM XXCoder: if cant fit .001" shim under anywhere its flat enough
06:40 AM XXCoder: otherwise I go to vise and bend it around
06:41 AM XXCoder: gets boring when its usually over 100 part lots.
06:41 AM XXCoder: havent had that order for a year now though, wonder if we kicked it off or expired contract
06:43 AM XXCoder: i'll never forget that nightmare of a part, thankfully I never ran it
06:43 AM XXCoder: it has pairs of ears all over
06:43 AM XXCoder: and gap between ears is .0005+ - 0
06:44 AM XXCoder: such a strange part.
06:44 AM jthornton: a bit of burr and your out of spec?
06:45 AM XXCoder: dunno how they deal with that shit
06:45 AM XXCoder: never ran it, thankfully
06:45 AM XXCoder: hope it never darkens my machine door
06:45 AM jthornton: lol
06:46 AM jthornton: I feel like crap again today
06:46 AM XXCoder: i mean, you wouldnt be able to fit hair between whatever part is supposed to go into that part and that part.
06:47 AM XXCoder: that sucks
06:47 AM XXCoder: hope you get better )
06:47 AM XXCoder: :)
06:48 AM jthornton: yea rode 10 miles on the road bike yesterday and felt like crap when I got home
06:50 AM Loetmichel: sensille: if you have a 3dprinter: https://www.thingiverse.com/thing:3268462
06:51 AM sensille: *collect* :D
06:51 AM XXCoder: fancy'
06:52 AM XXCoder: honestly dunno bec of aliexpress
06:52 AM XXCoder: https://de.aliexpress.com/wholesale?catId=0&initiative_id=SB_20190726034729&SearchText=loc-line&switch_new_app=y
06:52 AM XXCoder: oh stoll in germany mode. jeez
06:53 AM XXCoder: hate how visiting link by other people change language
06:55 AM XXCoder: usa link https://www.aliexpress.com/wholesale?catId=0&initiative_id=SB_20190726035028&SearchText=loc-line&switch_new_app=y
06:57 AM sensille: searching for "mist coolant" brings much more results
07:00 AM XXCoder: tend to be better yea
07:44 AM * Loetmichel is just printing a set of 1/2" locline parts from my link above... lets see if the work 3dprinted :-)
07:46 AM sensille: the question is: do i trust them with air pressure?
07:46 AM XXCoder: i was thinking maybe layers would seperate when you move it arounds
07:47 AM * sensille can't print ABS or hasn't tried yet
07:51 AM * Loetmichel is doing PLA ;)
07:51 AM Loetmichel: XXCoder: we'll see ;)
07:52 AM Loetmichel: sensille: PLA is surprisngly robust. i have no problem trusting them with 8 bar
07:52 AM XXCoder: cool :)
07:52 AM sensille: Loetmichel: do you also print the connector for the hose?
07:52 AM Loetmichel: i am worried if they are still moveable because of the layer structure
07:53 AM Loetmichel: i am printing an 1/2" npt adapter
07:53 AM Loetmichel: at 0.15mm layers it can do withworth/pipe threads surprisingly well
08:28 AM sensille: Loetmichel: printing on both enders in parallel?
08:44 AM Loetmichel: sensille: actually i do the locline on the Anet
08:44 AM Loetmichel: both enders do company stuff ;)
08:44 AM Loetmichel: (USB-Dreh)
08:49 AM Loetmichel: sensille: i LIKE that roll of transparent blue PLA... http://www.cyrom.org/palbum/main.php?g2_itemId=17436&g2_imageViewsIndex=1
08:50 AM sensille: Loetmichel: :) I want that one: https://www.dasfilament.de/filament-spulen/pla-1-75-mm/223/pla-filament-1-75mm-magenta
08:51 AM Loetmichel: nice bright colour
08:57 AM Loetmichel: fun: i just noticed: that blue stuff is PETG, not PLA... prints on 215° just the fine though, sometimes one has to have luck! ;)
09:06 AM esch: lol
10:13 AM Loetmichel: maan, i should know by now NOT to trust Cura4 print time estimates... sitting here at work, 7 minutes past five, looking at the printer: "49% done"... and it already printed 2.5 hours... *sigh* (and no i will NOT let an Anet A8 print unsupervised...)
10:42 AM JT-Shop: pcw_home: can a 7i74 plug into a 7i76e?
10:44 AM sensille: Loetmichel: aren't you the supervisor? just tell someone to stay until it's finished and go home
10:49 AM Loetmichel: i am
10:49 AM Loetmichel: and i did
10:49 AM Loetmichel: coworker only stays until 19:00 though
10:50 AM Loetmichel: if its not finished then... he will let it print and when he comes to work saturday he will switch it off... IF there still is a company to come to ,)
10:55 AM pcw_home: JT-Shop: sure, using 7i76e_7i76x1_7i74x1D.bit firmware for example
10:56 AM jthornton: thanks
10:57 AM pcw_home: (thats 8 sserial ports on the 7I74 7i76e_7i76x1_7i74x1SSID.bit is 8 SSI absolute encoders on the 7I74)
10:58 AM jthornton: interesting
11:01 AM jthornton: does an absolute encoder use 3 pair for A B and Z and 1 pair for power like a regular encoder?
11:05 AM pcw_home: No, SSI is just one TX and one RX pair (and power)
11:05 AM pcw_home: same with BISS and Fanuc
11:06 AM pcw_home: so compatible with 7I74/7I44 for example
11:07 AM jthornton: ok, thanks
11:17 AM pcw_home: Absolute encoders typically do not have an index (since you can derive the index from the count)
11:19 AM pcw_home: For example one of my test SSI encoders is 24 bits (12 bits per turn (1/4096) and 12 bit turn count)
11:20 AM pcw_home: older multi-turn absolute encoders use gears to remember the turn count
11:22 AM pcw_home: newer one like Fanuc etc use batteries, still newer one use the Wiegand effect to generate power when they are turned an keep the backup supply charged
01:43 PM JT-Shop: I wondered how they worked
03:01 PM * Loetmichel snickers... now i know why that 400W seasonic PSU was in the "trash bin" at the company... built it into my new PC here for testing: it chirps in sync with the CPU load... and LOUD... probably the filtering caps on the secondary power rails dead ;)
03:07 PM jym: lol
03:20 PM Loetmichel: maaan the "joy" of installing a 10 year old OS on a new gaming rig... Win7 update found 843 new updates... *rebooot* update found 382 new updates... *rebooot* update found 128 new updates... *rebooot* ... i am curious how many reboots it will take to have "no more new updates found" ;)
03:20 PM gregcnc: don't they have installs that have most of the updates?
03:22 PM Loetmichel: gregcnc: nope. it IS the "latest" image you can get from M$
03:22 PM Loetmichel: already with servicepack 3 integrated
03:22 PM methods_: yeah it's almost like they don't want you to install win7 or something
03:23 PM Loetmichel: STILL gets tons of updates before you can "work" with it
03:23 PM Loetmichel: methods_: also an indicator how desperately they are trying to upsell you to win10 ;)
03:23 PM methods_: shocking
03:24 PM JT-Shop: try installing XP...
03:24 PM gregcnc: years ago I found a third party source for XP64 that had most everything in it
03:25 PM gregcnc: https://www.raymond.cc/blog/create-an-integrated-up-to-date-windows-7-install-disc/
03:30 PM jthornton: I need xp32 to run an old version of solidworks
03:33 PM gregcnc: i was running SW 2007 or 8 at the time i think
03:35 PM jthornton: I have 2010 and 2011 somewhere
03:36 PM gregcnc: I still have the XP64 ISO I made with SP3. Ah they call updating the ISO slipstreaming
03:43 PM Deejay: gn8
03:44 PM gregcnc: The elusive 10mm socket https://youtu.be/2jlxO6s5N6Q
04:27 PM miss0r|office2: Right.. I'm having some people over for a huge ass BBQ (Iberico baby back ribs only)... I just put'em all in the sous vide. (A sous vide is a temperature controlled water bath, where the meat is put in inside of a vacuum bag)
04:27 PM miss0r|office2: Turns out I did not have a container large enough to hold all of the ribs... (17ish kgs of ribs)
04:28 PM miss0r|office2: So I combined two.. having the heater unit in one and a 12volt submersive pump in there with it, to fill water into the other container, which then spills back over into the first one.
04:28 PM miss0r|office2: not ideal, but what is a guy to do? :D Now I just cross my fingers that 12v pump can handle 74degree celcius temperatures at continous load :D
04:33 PM JT-Shop: sounds like a good plan
04:41 PM miss0r|office2: also, it would seem I have some issues
04:41 PM * Tom_L throws in the towel and calls it a day
04:41 PM miss0r|office2: The heater element is not powerfull enough to pull the temperature up higher than 60c
04:41 PM miss0r|office2: it needs to be at 75...
04:41 PM miss0r|office2: Where the hell would I get a thermo box that size at 20 minuts to midnight?!
04:42 PM Tom_L: JT-Shop do you have xp?
04:43 PM Tom_L: 2004 runs on 7
05:02 PM gonzo_: CaptHindsight, could you paste in your rtload hm2_7990 line please, to go with your working CH382L card?
05:02 PM gonzo_: I've been trying combinations and not found anything that will work
05:03 PM gonzo_: I get a message in the popup box that linuxcnc can't find the card
05:03 PM gonzo_: but I see it in lspci, as I posed last night
05:04 PM CaptHindsight: I have a CH382L in a system but it's not connected to a Mesa card at the moment
05:04 PM CaptHindsight: maybe over the weekend
05:05 PM gonzo_: you've had the combination working?
05:05 PM CaptHindsight: the CH382L shows up in LSPCI, the mesa card won't
05:05 PM CaptHindsight: post your LSPCI -VV, lets see which driver is loaded
05:06 PM CaptHindsight: sudo lspci -vv
05:06 PM CaptHindsight: cut-n-paste this ^^
05:06 PM gonzo_: mine shows in lspci but as a serial device. But I read something about the chip being a big serially addressed things?
05:06 PM gonzo_: from yesterday:
05:07 PM gonzo_: https://paste.ubuntu.com/p/F22YgyMt8m/
05:08 PM gonzo_: let me run up, and will see if I can paste the error I get
05:08 PM gonzo_: need to go to other building.......
05:12 PM jym: Awww, andy not here
05:12 PM jym: CaptHindsight: Did you kidnap andy... again?
05:18 PM CaptHindsight: gonzo_: people say all sorts of crap
05:18 PM CaptHindsight: it's an LPT card
05:19 PM CaptHindsight: jym: he's probably out having fun
05:20 PM CaptHindsight: anyway, still working
05:20 PM jym: CaptHindsight: THAT BASTARD,, and didn't invite us?!
05:25 PM JT-Shop: invite you to work with him?
05:26 PM gonzo_: ok, the output from linuxcnc popup:
05:26 PM gonzo_: https://paste.ubuntu.com/p/GvFmdwCJr8/
05:28 PM JT-Shop: that's pretty much the same error I got with the pcie card
05:28 PM gonzo_: line 44 is what I meant by board not being found.
05:29 PM JT-Shop: line 30 looks like the first error
05:31 PM gonzo_: is line 44 saying that the hm2 could not find that lpt card at addr 0xec00?
05:32 PM JT-Shop: it's not super clear to me exactly what the error is, I just looked at my flash pc and it has a parallel port
06:07 PM jym: JT-Shop flash pc?
06:08 PM jthornton: yep it flashes people when they come in the machine shop
06:11 PM gonzo_: dirty bugger
06:11 PM jthornton: lol
07:26 PM Vitran: https://drive.google.com/open?id=1JmYEv63aQxtV7X55QjuGtZ8wFALc136p
07:26 PM Vitran: Electric boat project
07:26 PM Vitran: This is the old battery pack.
07:27 PM Vitran: https://drive.google.com/open?id=1L1j3F7NGj1DlQS7i2GTRVdce8vk1rfUv
07:31 PM Vitran: This was what it was like in the boat after getting a better battery pack https://drive.google.com/open?id=1PaBaeHHJvrNtLQbTMlqFxvvlBXUgV8UY https://drive.google.com/open?id=1PneHakO-6mdkmp25Bdh5P0Qym8B9h5bK
07:31 PM Vitran: It was a 10kW motor and driver off of aliexpress for about $800
07:32 PM Vitran: Overall, neat project. The boat was garbage. Didn't know if anyone else has done something like this
08:29 PM Tom_L: just keep oars in it
09:05 PM CaptHindsight: gonzo_: https://forum.linuxcnc.org/38-general-linuxcnc-questions/31715-pci-e-parallel-card-problem is this your card?
09:07 PM CaptHindsight: 0xec00 is what to use for the LPT address
09:12 PM CaptHindsight: gonzo_: your .hal file should have this line: loadrt hal_parport cfg="0xEC00"
09:17 PM CaptHindsight: and it obviously already does since the error you got after trying to run LCNC is about 7i90 firmware
09:18 PM CaptHindsight: hm2: loading Mesa HostMot2 driver version 0.15
09:18 PM CaptHindsight: hm2_7i90: loading HostMot2 Mesa 7i90 driver version 0.3
09:18 PM CaptHindsight: hm2_7i90: failed to clear EPP Timeout!
09:18 PM CaptHindsight: hm2: no firmware specified in config modparam! the board had better have firmware configured already, or this won't work
09:18 PM CaptHindsight: hm2_7i90.0: EPP timeout on data cycle of read(addr=0x0100, size=4)
09:18 PM CaptHindsight: hm2_7i90: failed to clear EPP Timeout!
09:20 PM CaptHindsight: http://linuxcnc.org/docs/html/man/man9/hm2_7i90.9.html
09:22 PM CaptHindsight: gonzo_: see ^^
09:22 PM CaptHindsight: gonzo_: how long is the LPT cable between the LPT card and the 7i90?
09:24 PM CaptHindsight: is it a true https://en.wikipedia.org/wiki/IEEE_1284 compatible cable
09:24 PM CaptHindsight: lots of cheap LPT cables don't support ALL the signals
09:26 PM CaptHindsight: https://forum.linuxcnc.org/27-driver-boards/32407-7i90-flashing
11:48 PM pink_vampire: any life?
11:50 PM XXCoder: https://upload.wikimedia.org/wikipedia/en/thumb/f/fa/Half-Life_Cover_Art.jpg/220px-Half-Life_Cover_Art.jpg
11:50 PM pink_vampire: ??
11:51 PM XXCoder: joking heh
11:51 PM XXCoder: its game called half life
11:54 PM XXCoder: i got lucky at work 2 days ago heh
11:54 PM XXCoder: got another one of those expensive cnc lighting :)
11:54 PM pink_vampire: https://www.youtube.com/watch?v=Ym8JjY4fy-M first 2 comments here LOL
11:54 PM XXCoder: driving and ikea?
11:55 PM pink_vampire: XXCoder: I Maeve Maeve 5 years ago Alright, everyone! I'm off to save the world! :D
11:55 PM pink_vampire: I working on acrylic parts 20" long
11:56 PM pink_vampire: my table x travel is only 17"
11:56 PM pink_vampire: fun
11:56 PM XXCoder: indeed
11:56 PM XXCoder: using keys to move part to finish?
11:59 PM pink_vampire: I'm trying keys and probing but 60K rpm vs acrylic with no cooling =
11:59 PM pink_vampire: arts and craps pile growing up every second
11:59 PM pink_vampire: but I'm learning
11:59 PM XXCoder: dont it fuse into tool?
