12:12 AM -!- #linuxcnc mode set to +v by ChanServ
01:00 AM _unreal_: finally got a bunch of tasks finished I've been needing to do on the new cnc
01:00 AM _unreal_: getting closer
01:07 AM fjungclaus1 is now known as fjungclaus
01:22 AM Loetmichel: mornin'
01:38 AM Loetmichel: *MAAN* That day starts well... first the fuel station bought coffee fell over and poured over the middle console in the car. Then i arrive at the company to see that the 3dprinter ran out of filament half way thru the print this night :(
01:47 AM veegee: These indicator holder magnetic bases are great general purpose magnets. Awesome for welding, sticking things to the fridge, etc.
01:47 AM veegee: Also magnets extracted from 3.5" 15k enterprise SAS drives
01:50 AM * Loetmichel just buys pourpose made magnets at supermagnete.de
03:34 AM rtce9a: hi
03:34 AM rtce9a: im having trouble connecting my linuxcnc to my parrallel breakout board
03:37 AM rtce9a: im using pcie parallel port card, when connecting to the breakout board its not working, Ive wired the breakout board with X axis when trying to move axis it does nothing
03:44 AM Deejay: moin
03:48 AM rtce9a: i think its my pcie parallel port cards the issue
03:51 AM rtce9a: lspci -v the output shows i have "Serial controller: Device 1c00:3250 (rev 10) (prog-if 05 [16850])"
04:06 AM cpresser: indeed, that is weird. do you have a picture of the card? with visible/reabable chip markings?
04:09 AM rtce9a: cpresser, https://www.ebay.com/itm/RS232-RS-232-Serial-Port-COM-DB25-Printer-Parallel-Port-LPT-to-PCI-E-PCI-Expre/193310802473?_trkparms=aid%3D1110001%26algo%3DSPLICE.SIM%26ao%3D2%26asc%3D20160323102634%26meid%3D8d72e74e1ca14281b6f42266dbc00543%26pid%3D100623%26rk%3D4%26rkt%3D6%26sd%3D183132128667%26itm%3D193310802473%26pmt%3D0%26noa%3D1%26pg%3D2047675&_trksid=p2047675.c100623.m-1
04:10 AM rtce9a: thats same car i brought from aliexpress
04:10 AM rtce9a: *card
04:12 AM cpresser: it says in the name that its a serial port card
04:13 AM cpresser: you need to get a parallel port card instead.
04:15 AM rtce9a: can you recommend the parallel card with the right driver for linux cnc
04:16 AM rtce9a: what about this card http://store.mesanet.com/index.php?route=product/product&path=83_85&product_id=58
04:20 AM p0g0_: The DB25 Parallel port in that URL suggests that the card is both a com and LPT port.
04:21 AM p0g0_: And looking at the picture, it has the DB25 hood, so it's likely that it does have LPT1
04:22 AM Loetmichel: MAAAN that new flux in the Aluminium low temp solder is garbaaage... dosent get rid of the oxide, clumps up instead of maling the solder flow, works only right below the melting point of Al. Have a spool of old solder from the same manufacturer, same order number: works like a charm New stuff: http://www.cyrom.org/palbum/main.php?g2_itemId=17660&g2_imageViewsIndex=1 ... i suspect EU
04:22 AM Loetmichel: regulations about poisonus stuff. :-(
04:22 AM cpresser: true, i was pretty fast and did not read everything.
04:32 AM rtce9a: i found the link to chipset WCH CH382L PCI-E driver http://wiki.linuxcnc.org/cgi-bin/wiki.pl?WCH
04:33 AM rtce9a: do i need to patch the kernal to get the card to work ?
04:36 AM rtce9a: any suggestion to get this card to work ?
04:41 AM rtce9a: if i was to test the port as suggested on this link http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Parallel_Port_Tester do i need to probe the pinout with multi meter ?
04:55 AM jthornton: morning
04:56 AM XXCoder: yo
05:01 AM Tom_L: morning
05:02 AM XXCoder: yo
05:02 AM jthornton: well they dropped snow from the forecast
05:02 AM XXCoder: it snowed here
05:02 AM XXCoder: all cleared up and cold now
05:03 AM * Javabean still has snow in his forecast
05:15 AM Tom_L: 32°F, Lo 23
05:16 AM Tom_L: says we might get a little snow but who knows...
05:17 AM Tom_L: couple days ago it was 73
05:19 AM XXCoder: heh it rarely varies that much here in winter
05:19 AM p0g0_: When I was a Plant Science major in college, it was often stated that >40F day/night|24hr shifts makes deserts in pretty short order.
05:28 AM -!- #linuxcnc mode set to +v by ChanServ
07:11 AM pink_vampire: hi
07:17 AM Loetmichel: hihi, just searched for 608zz ball bearings yesterday... first link: RS components: 5.80€ per piece. second link: kugelager-express.de: 0.30€ per piece... ordered 50pcs. Aaaand already here... now i have to print a dozen more spool stands for the filament ;)
07:47 AM elmo40: why do you need that many rotating stands?
07:47 AM elmo40: just keeping them all on the spools until empty?
08:00 AM gregcnc: elmo40 cnc controls don't dither steppers
08:01 AM gregcnc: conisder teh case of a non cartesian machine where probably no step position in the workspace is exactly equal to commanded position, not a problem
08:09 AM Loetmichel: *MUHAHAHA* Coworker just asked if he can use the lathe. $me:"sure, i'll cut you some off that 20mm round stock alu" ... put the stock in the vice, Metal hacksaw: * ziggaziggaziggazig:ahhh!*. Coworker tries to catch the falling part... *scream* "THATS REALLY HOT!?!" $me: grinning and laughing.
09:19 AM perry_j1987: hows it going guys
09:22 AM SpeedEvil: Loetmichel's torturing coworkers, so a normal day.
09:29 AM perry_j1987: haha
09:30 AM perry_j1987: tried and failed to get the modbus working
09:30 AM perry_j1987: so reverted back to 0-10v speed control
09:35 AM Loetmichel: SpeedEvil: i am not
09:36 AM Loetmichel: he was torturing himself. He didnt think that my visible work done has to go SOMEHWERE so he tried to catch the cutoff.
09:36 AM Loetmichel: ... which was indeed pretty funny
09:36 AM SpeedEvil: Slight hyperbole.
09:37 AM Loetmichel: i mean: he could see and hear that i did put some effort into sawing that thing off
09:37 AM Loetmichel: :-)
09:38 AM Loetmichel: ... metal tends to get hot if you take less than a minute to cut off a 20mm round stock with a hacksaw
09:38 AM Loetmichel: even if its only alu ;)
09:41 AM perry_j1987: so was trying to figure out this speed control thing if i tell it to do 24,000 rpm the vfd shows 382hz instead of 400
09:41 AM perry_j1987: put multimeter on the pins and its reading 10.38v when i tell it to do 24,000 rpm
09:41 AM Loetmichel: perry_j1987: probably the max it can do?
09:42 AM perry_j1987: the vfd is set to 400 for upper threshhold
09:42 AM perry_j1987: it worked on mach3
09:42 AM perry_j1987: but i havnt figured it out since moving the machine to linuxcnc
09:42 AM Loetmichel: ah, maybe the rc filter that converts the PWM to a voltage isnt reaching 10V?
09:43 AM perry_j1987: its 10.38v
09:43 AM perry_j1987: slightly higher
09:48 AM perry_j1987: this breakout board takes a pwm signal and converts it to analog
09:53 AM perry_j1987: not sure what to do
09:54 AM perry_j1987: the vfd doesnlt let you specify voltage above 10 for its scale
09:54 AM perry_j1987: but the voltage is slightly higher than 10 so it should be giving the full 400 i'd think
10:11 AM SpeedEvil: Is the '10.38' smooth DC?
10:12 AM SpeedEvil: Multimeters can be very variable if they are not fed smooth DC or sinewave AC at 50/60Hz
10:14 AM perry_j1987: i'll have to scope it
10:14 AM perry_j1987: i assume the spindle speed would fluctuate if it wasnt smooth
10:17 AM jymmmm: Good morning
10:20 AM perry_j1987: got to charge up my scope accidentaly left it on (one of those mini portable scopes lol) VERY handy little tools
10:22 AM jymmmm: perry_j1987: link?
10:25 AM perry_j1987: https://amzn.to/380AxhJ like that
10:25 AM perry_j1987: mine is older version though
10:26 AM SpeedEvil: perry_j1987: Alternatively, take a known DC source (9V bat say) connect, measure, look at RPM, and vary commanded RPM till PWM voltage reads 9v
10:27 AM perry_j1987: whats confusing is that commanding it to the full 24,000 rpm
10:27 AM perry_j1987: is giving 10.38v
10:28 AM perry_j1987: you'd think that'd the vfd would take that and do the full 400hz
10:50 AM perry_j1987: there we go got airline ran to new mill location
10:51 AM SpeedEvil: :)
10:56 AM unterhaus: people are still talking about redoing lcnc on the email list. The way I see it, if lcnc is to be redone, it will be a totally different project
10:57 AM SpeedEvil: redone?
10:57 AM SpeedEvil: You mean to relicence, or some other reason?
10:57 AM unterhaus: future of linuxcnc
10:59 AM unterhaus: the original notion was that it's not commercially viable in its current form
11:00 AM SpeedEvil: 'those insane people are giving it away!'
11:00 AM unterhaus: well, more that it isn't good enough
11:01 AM unterhaus: and should be something else to be good enough
11:02 AM unterhaus: I tried to talk my boss into using it and he asked someone at nist if it was a good idea
11:02 AM unterhaus: of course, they said no. Better to use the crap software that you don't have any idea what's going on
11:03 AM unterhaus: the nist version wasn't that great.
11:03 AM unterhaus: they did stuff like reuse variable names in a subroutine
11:03 AM unterhaus: to mean something totally different
11:04 AM perry_j1987: doesnt tormach use linuxcnc?
11:04 AM gregcnc: what is the alternative? Fanuc?
11:04 AM gregcnc: perry_j1987 yes
11:04 AM unterhaus: there are a lot of commercial alternatives. We were using deltatau, which is not great
11:08 AM unterhaus: I was thinking Centroid had a diy kit that used lcnc, but I don't see that on their site
11:09 AM gregcnc: I think they used to. I ran into some fragments of a page years ago that eluded to it
11:11 AM unterhaus: I think linuxcnc would be great for the machine I wanted to put it on. At least you could get the kinematics right
11:12 AM unterhaus: relatively safe and contained
11:20 AM SpeedEvil: But it doesn't come with a maintainance contract and isn't half run in the cloud with a service guaranteed to last at least two years.
11:23 AM unterhaus: we didn't have a service contract, per se
11:23 AM unterhaus: ala carte and the answer to cnc problems was a $25000 upgrade to a new version that they wrote themselves
11:24 AM unterhaus: I think it still used the delta tau libraries, but not sure
11:26 AM gregcnc: but how would you handle it with linuxcnc? would it be any different?
11:29 AM perry_j1987: so linuxcnc needs service providers taking it on eh
11:29 AM unterhaus: there were some things that just didn't work
11:29 AM unterhaus: and $$ to do stupid little upgrades
11:30 AM gregcnc: sure but doesn't it cost money to add something to linuxcnc?
11:30 AM unterhaus: order of magnitude cheaper
11:30 AM gregcnc: that's their profit and overhead
11:31 AM unterhaus: sure, spending other people's money, get the official software
11:32 AM unterhaus: but the main difference is you can't see their code so you don't have to worry until it does something hinky
11:32 AM gregcnc: never happens in linuxcnc?
11:32 AM gregcnc: just being real here
11:33 AM unterhaus: this was a custom machine in the first place, retrofit to mostly match a commercial project
11:33 AM unterhaus: not sure what the argument is here
11:33 AM unterhaus: everything is a compromise
11:33 AM gregcnc: i'm curious how linuxcnc changes the picture
11:33 AM unterhaus: transparency?
11:34 AM unterhaus: the machine gets reconfigured a lot, fits the linuxcnc model a bit better
11:35 AM gregcnc: ah that's would be a big difference
11:37 AM unterhaus: if nothing else, the provisions to tune the gains weren't great, and the machine really needs to be tuned
11:56 AM * JT-Shop just got paid for a job with a wad of bengies... I like that kind of job
11:59 AM -!- #linuxcnc mode set to +v by ChanServ
11:59 AM cradek: I once had a guy fed-ex me several money orders (the total was more than he could get on one money order). I assume he wasn't exactly participating in the same economy and government in the same way I am...
12:00 PM SpeedEvil: Or a market sector that is almost precluded from banking but is legal.
12:00 PM Loetmichel: what are bengies?
12:01 PM unterhaus: 100 dollar bills
12:01 PM Loetmichel: ah
12:01 PM gregcnc: 90.58Euro bills
12:01 PM unterhaus: Benjamin franklin is on there
12:01 PM JT-Shop: Benjamin Franklin
12:02 PM JT-Shop: I don't have a problem making things for friends for cash
12:02 PM unterhaus: All about the Benjamins
12:02 PM cradek: SpeedEvil: it was just a machine shop...
12:03 PM cradek: otoh, if everyone would fedex me money orders it might be cheaper than paypal fees
12:03 PM unterhaus: the only machine shops I have had dealings with were all P.O. and invoices
12:04 PM SpeedEvil: Today I accepted delivery of 10*4800*45*195mm wood, paid for by paypal from the builders merchant.
12:05 PM JT-Shop: and if a friend wants to learn how to make something they need, I'll teach them free
12:06 PM JT-Shop: yea if it's a company they get an invoice and I get a check
12:07 PM JT-Shop: https://gnipsel.com/images/log-arch/
12:08 PM JT-Shop: I made that for free as my friend did lots of work on it
12:21 PM perry_j1987: nice fusion360 is outputting zero kb gcode all of sudden without popping up any errors
12:22 PM unterhaus: I kinda lost faith in fusion, but the engineering students love it
12:23 PM unterhaus: I keep intending to pick it up again once I get a better video card
12:23 PM gregcnc: Industry 4.0
12:26 PM * JT-Shop needs a simple wire stripper design...
12:35 PM unterhaus: I always figured that HAL would have just ghosted Dave, but that wouldn't have been good for a movie
12:35 PM Loetmichel: JT-Shop: two pieces of steel pallet wrapping tape made into a "tweezers" wit the front sharpened?
12:37 PM SpeedEvil: unterhaus: HAL tried to ghost dave.
12:37 PM SpeedEvil: Turns out he could hold his breath.
12:37 PM unterhaus: no, but HAL kept telling him he was doing
12:38 PM unterhaus: IRL, HAL would have just ignored him
12:39 PM unterhaus: I saw that movie when I was 10, understood nothing
12:39 PM Loetmichel: what is "ghosting" in this context?
12:41 PM JT-Shop: Loetmichel, that doesn't sound very consistent to me
12:42 PM Loetmichel: https://www.distrelec.de/Web/WebShopImages/landscape_large/_t/if/abisolierer-fur-lackdraht.jpg
12:42 PM Loetmichel: that i was describing
12:42 PM Loetmichel: but i stand corrected: thats only for magnet wire
12:48 PM unterhaus: "ghosting" is when you ignore someone. Usually in the context of ignoring their calls, emails and text messages
12:49 PM Loetmichel: ah
12:49 PM unterhaus: I think that it could imply killing someone, which HAL did with everyone but Dave and then tried to kill dave
12:50 PM unterhaus: not a common usage at all
12:53 PM unterhaus: I bought a Dell that has a weird port on the back. They have no pictures of the back panel in any of the manuals
12:53 PM unterhaus: I think it might be a misshapen displayport.
12:56 PM unterhaus: it has 10 external usb ports, seems excessive
12:56 PM JT-Shop: Loetmichel, what is that for? I need to strip THHN and MTW wire in long pieces to recycle
12:57 PM JT-Shop: ah ok to strip the lacquer off of magnet wire
12:57 PM Loetmichel: JT-Shop: stripping the paint off of magnet/enamel wire
12:57 PM unterhaus: the local scrappers just burn wire. And also when they steal copper pipe they burn it
12:58 PM unterhaus: my neighbor had some copper pipe in his cabin. They burned it and it didn't come apart because of the fittings he used
12:58 PM JT-Shop: http://copper-wire-stripper.com/products/machines/bws-60
12:58 PM unterhaus: so they just left it in his wood stove
12:59 PM JT-Shop: damn
12:59 PM Loetmichel: unterhaus: if i had problems with people stealing wire i would probably leave a bit of fat "wire" laying around that has some explosives in it
12:59 PM JT-Shop: well 1/2 of the big work table is clean
12:59 PM Tom_L: time to start a new project then
01:03 PM unterhaus: so they built a fire in his wood stove, with his wood, threw his copper pipe in it and drank beer while they were throwing his wood pile in their truck.
01:04 PM SpeedEvil: https://imgur.com/gallery/1n0UCjt Multi axis cheesechanger
01:04 PM unterhaus: that was when I decided I didn't want a cabin
01:06 PM perry_j1987: ok... what the hell... i got some tested gcode that i've been using for long while
01:06 PM perry_j1987: all of sudden its plunging down in random area and then going to make the cut in diff area
01:06 PM perry_j1987: how ... is that even possible
01:08 PM JT-Shop: http://copper-wire-stripper.com/products/manual-strippers/bws-38-multi-feed-da
01:08 PM JT-Shop: a simpler version of that maybe
01:14 PM Tom_L: how much wire you plan on stripping?
01:26 PM JT-Shop: I have piles of wire...
01:26 PM JT-Shop: probably 200 pounds or more
01:30 PM Tom_L: burning not an option?
01:30 PM Tom_L: probably toxic
01:32 PM perry_j1987: sell it on amazon in 5' lengths :P
01:38 PM unterhaus: a relative used to do that with kimonos, 1 square foot pieces
01:42 PM JT-Shop: it's not #1 copper if burned AFAIK here
01:42 PM JT-Shop: and burning is a real mess, tried it once
01:46 PM unterhaus: that makes sense. wonder if a hot wire knife would work
01:48 PM JT-Shop: for solid core all you need is two smooth rollers for thhn I'd bet you need a V roller and a cutting roller
01:57 PM gloops: tie it to a tree and keep it tight, slice down it with a stanley knife
01:58 PM gloops: seems the favoured method here going by the piles of plastic sheathing down the woods
01:59 PM gloops: you can walk towards the tree slicing, thats assuming the copper is thick enough strands for the blade to ride over
02:05 PM jthornton: hmm I wonder if a draw knife would work if sharp...
02:08 PM jthornton: hot damn the chicken media player is working finally guessed enough times...
02:10 PM CaptHindsight: rtce9a: did you get the WCH CH382L PCI-E LPT port to work?
02:11 PM CaptHindsight: rtce9a: "This driver was added to the kernel for Dev. ID 3050, Date: Sat, 26 May 2018, Kernel 4.14, Debian also back ported this to earlier kernels since it is working with Kernel 4.9 "
02:11 PM CaptHindsight: rtce9a: which kernel version are you using?
02:15 PM CaptHindsight: rtce9a: uname -r command will tell you
02:28 PM syyl: burning wire to get rid of the insulation makes you a bad person.
02:29 PM syyl: thats like burning tires in your yard.
02:32 PM miss0r: syyl: or like owning more than one land rover...
02:37 PM CaptHindsight: how many Land Rovers does it take to make you happy? :)
02:39 PM miss0r: Good question :)
02:39 PM miss0r: for now two will suffice
02:41 PM miss0r: Not in a realy good shape this new one. The spark plug leads are all leaky like you would not believe it. I didn't even need to do the screwdriver'n jumper lead trick to discover bad insulation. I just had to idle the engine in the dark... it was all too clean then :D
02:42 PM CaptHindsight: wow, that is bad
02:43 PM miss0r: yeah, but still a rater easy fix..
02:43 PM CaptHindsight: one banana job
02:44 PM miss0r: sure.. I changed the oil all 9 places... :D
02:45 PM miss0r: I am fitting an oil pressure gauge to monitor the health while driving.. Once I have completed that and swapped out the spark plugs & leads I'll take it for a cruise :)
02:45 PM CaptHindsight: is every gasket and seal dried up as well?
02:45 PM miss0r: you DO know land rovers soak in oil inside'n out, right?
02:46 PM miss0r: The swivel house seals are bad, but replacements have been ordered
02:46 PM miss0r: :D
02:46 PM CaptHindsight: why you park them over puddles of oil so that they get a drink while parked
02:46 PM miss0r: "When the land rover engineers started designing the first land rover, they threw a bucket of oil on the shop floor and build their way up from there"
02:47 PM JT-Shop: a buddy with a Norton 650 says it's marks it's territory lol
02:47 PM miss0r: yeah, thats a common way of looking at a land rover too :)
02:48 PM miss0r: the land rovers keep their chassis rust free by a patented "outside centrifugal lubrication system"(R)
03:01 PM unterhaus: guess I need to find a 3d printer to make some parts for my stmbls
03:36 PM CaptHindsight: maybe someone will cobble up a sheet metal enclosure for the STMBL drive
03:37 PM CaptHindsight: CNC or laser cut some holes and indicate where to fold
03:38 PM pcw_mesa: That's been done AFAIK
03:38 PM CaptHindsight: i thought I had seen them before :) https://www.youtube.com/watch?v=i6rJsCKzUK0&feature=emb_logo
03:40 PM unterhaus: yeah, I priced out the stmbl enclosures, about $18 apiece
03:41 PM unterhaus: probably do it, maybe not initially
03:43 PM Tom_L: CaptHindsight, i thought andypugh had one of those already
03:43 PM unterhaus: those came from Andy, but he got them from one of the europeans
03:44 PM unterhaus: I just realized I have six stmbls, 5 heatsinks. Oops
03:44 PM unterhaus: don't think I'll need 6
03:45 PM CaptHindsight: where did skunkworks get his or are his the older version?
03:45 PM unterhaus: Andy
03:46 PM unterhaus: it's pretty involved to make the circuit boards. Almost all of them have been group buy
03:46 PM andypugh: I seem to recall that Dean Forbes made them. But I made the screen for printing them.
03:47 PM unterhaus: but you did the sheet metal, correct?
03:48 PM andypugh: No, Dean had the sheet metal laser cut to Crinq(?)s design.
03:48 PM andypugh: But I did make one by hand ot my own version of the design (which the finel design was based on).
03:48 PM andypugh: https://photos.app.goo.gl/mGJ8ON0pCHNtoXCQ2
03:50 PM unterhaus: that hand made one is like something I would have done 30-odd years ago
03:51 PM unterhaus: I found one of my old projects and was impressed that I used to have that much patience for using a nibbler
03:51 PM Deejay: gn8
03:52 PM andypugh: Do you like the mg-drill as a Magnabend hack?
03:53 PM unterhaus: that's pretty slick, didn't understand what I was looking at until you mentioned it
03:55 PM sync: unterhaus: ask rene_dev_, he has some of the raw lasercut cases left over
03:56 PM CaptHindsight: sync: happen to know if the new design is mechanically the same as the older one?
03:56 PM CaptHindsight: connector locations, heat sink etc?
03:56 PM Contract_Pilot: Long time all
03:57 PM Contract_Pilot: Anyone know a simple way to get wince to us Ez-USB FX2 drivers?
03:57 PM Contract_Pilot: Wine
03:57 PM sync: CaptHindsight: yes
03:58 PM Contract_Pilot: Would love to avoid having to put winblows on a PC
04:00 PM unterhaus: I thought I saw that the new design is not quite the same mechanically
04:01 PM unterhaus: andy asked that question and Rene answered "no, as the power and motor connectors will move a bit to make room for the screws
04:02 PM Contract_Pilot: Alll i can find is this greek site.. http://www.linux-usb.org/ezusb/
04:04 PM sync: ah yes the connectors are a bit too far to the left so you cannot fit the case
04:04 PM sync: but you can just snip the offending part out
04:05 PM CaptHindsight: sync: from the enclosure or the PCB? :)
04:06 PM sync: from the enclosure
04:06 PM CaptHindsight: pics near bottom of page https://github.com/rene-dev/stmbl
04:07 PM CaptHindsight: don't laugh https://en.wikipedia.org/wiki/Muntzing
04:08 PM CaptHindsight: "He carried a pair of wire clippers around and when he felt that one of his builders was overengineering a circuit, he would begin snipping components out. When the TV stopped functioning, he would reinsert the last part and leave the TV as it was."
04:12 PM Tom_L: wonder if boeing tried that
04:14 PM CaptHindsight: Tom_L: heh, yeah, but from what I've read it was a combo of similar engineering decisions and fudging of specs to regulators
04:15 PM CaptHindsight: https://www.marketwatch.com/story/boeing-emails-show-workers-mocking-faa-ridiculing-737-maxs-safety-2020-01-09
04:15 PM CaptHindsight: Boeing employee said 737 Max ‘is designed by clowns’ and ‘supervised by monkeys’
04:17 PM unterhaus: the story of what happened to Boeing is pretty sad
04:20 PM Tom_L: part of the issue was the airlines didn't want to retrain the pilots
04:21 PM unterhaus: but the bad management/engineering decisions had already been made at that point
04:22 PM unterhaus: the pilots that had no training actually kept the planes in the air longer than the ones that had training
04:23 PM unterhaus: part of the story is that boeing had a concerted PR effort to slander the pilots
04:26 PM CaptHindsight: they took a risk to cheat the rules, endanger passengers and save money and maybe lost
04:27 PM CaptHindsight: maybe in their eyes since they haven't really been punished yet besides the CEO being fired and given millions of $$
04:28 PM CaptHindsight: How does one get in line to be punished that way?
04:39 PM unterhaus: great question. Lots better to be fired than the relatively stressful job of running a company like that
04:40 PM unterhaus: whatever they gained by shoddy systems design they have lost by now
05:05 PM _unreal_: ve7it, sweet, my ds275 chips showed up
05:08 PM ve7it: _unreal_, excellent... glad you found some.... where did they come from?
05:10 PM _unreal_: china
05:10 PM _unreal_: I CANT see them not working.
05:11 PM _unreal_: I'm only missing a few resistors/caps at this point to finish the boards.
05:11 PM _unreal_: smd stuff that is
05:11 PM _unreal_: I still need to get the giant caps. I have yet to find a source.
05:11 PM _unreal_: for the psu
05:12 PM _unreal_: $$ cheap source
05:13 PM _unreal_: ebay has been a bit flaky on whats offered. and I dont really want to spend $70 for two caps from ebay. the goodwill stores have had few items likely to have the old amps with the caps I need
05:13 PM _unreal_: :/
05:13 PM ve7it: how about something off the boats... maybe chargers or invertors
05:14 PM ve7it: have you got any junkers?
05:14 PM _unreal_: naa
05:14 PM _unreal_: boats all use new hardware. everything is high freq psu's
05:15 PM _unreal_: I have not gotten off till 5 everyday so I dont get home till 6+ on average "thank you traffic"
05:17 PM _unreal_: I use too have a bunch of terminal caps but I got rid oof them before I moved to florida
05:19 PM _unreal_: There are some old 8 track, phonograph sterios at my local goodwill but they want $60 each for them and I dont even know whats in them. AND NO... returns
05:19 PM _unreal_: ass holes
05:27 PM jthornton: they won't let you test them in the store?
05:27 PM ve7it: jthornton, he is looking for some big caps for a power supply
05:28 PM jthornton: ah
05:28 PM ve7it: thus old stereo amps
05:28 PM jthornton: can't get them anymore?
05:28 PM * jthornton thought old caps went bad and got gray hair
05:29 PM _unreal_: jthornton, silver... wtf is wrong with you
05:29 PM _unreal_: gray....
05:29 PM jthornton: well mine is white I think...
05:30 PM _unreal_: I'm "phasing" into paper
05:30 PM _unreal_: pepper
05:30 PM jthornton: I started with red hair so no salt/pepper for me just red pepper
05:31 PM _unreal_: ve7it, I was looking at something. https://hackaday.io/project/15025-tarocco
05:31 PM _unreal_: in there code they have autotuning. looks interesting.
05:33 PM _unreal_: the motor(s) once installed into its finished device. does a set of movements and records its actions verses results and set's an assumed set of tuning ranges based on its self test results.
05:34 PM * jthornton gives the hens 5 more minutes before tucking them in
05:34 PM _unreal_: then again the cpu is a little more beefy
05:34 PM _unreal_: how does one tuck in a hen
05:35 PM jthornton: well it's just a bed check to see if everyone is present
05:35 PM _unreal_: I cant see someone putting a blanket on each one giving them a kiss on the head etc....
05:35 PM _unreal_: eh eh eh
05:36 PM jthornton: well one likes to be behind a towel and Monique I hold her for a while before she goes inside while waiting for the roost time rumble to quiet down
06:17 PM ve7it: _unreal_, looks like not a bad controller...
06:17 PM ve7it: but making them yourself means they will always be repairable and supportable
06:41 PM veegee: god damn americans and their dumb ass units of measurement
06:41 PM veegee: so damn hard to find metric micrometers and dial indicators, etc.
06:43 PM Tom_L: not really, most of them are dual display
06:44 PM perry_j1987: aye
06:44 PM Tom_L: https://www.amazon.com/Mitutoyo-293-340-30-Micrometer-Resolution-Specifications/dp/B00MBHXWGY/ref=pd_sbs_328_t_0/134-6921166-4139134?_encoding=UTF8&pd_rd_i=B00MBHXWGY&pd_rd_r=6a82a19c-3b49-4204-8adf-4f89ec46f7d6&pd_rd_w=9JtQ3&pd_rd_wg=tIAr1&pf_rd_p=5cfcfe89-300f-47d2-b1ad-a4e27203a02a&pf_rd_r=VQDC56TBF8PXY4PEEVV4&psc=1&refRID=VQDC56TBF8PXY4PEEVV4
06:45 PM veegee: Yeah that's the one I have
06:45 PM Tom_L: so what's the problem?
06:45 PM veegee: But for example finding a set of things like parallels, micrometers in various sizes
06:46 PM veegee: Should I get this: https://www.edgetechnologyproducts.com/pro-tram-system-01-000-10-000-09-000/ or this https://boringresearch.com/store/adjustable-spindle-square/
06:46 PM cerna: I enjoyed it too when I needed 5/4 UNC tap in Central Europe region. (But the truth is, I wasn't prepared to pay the over-the-counter price.)
06:47 PM Tom_L: veegee, i would just use a last word indicator
06:47 PM cerna: So, shug.
06:47 PM Tom_L: ^^ is just the lazy way out
06:47 PM cerna: *shrug
06:47 PM veegee: Never heard of such a thing, looking into it
06:48 PM Tom_L: https://www.amazon.com/Starrett-Last-Word-Indicator-Attachments/dp/B007WZQJTM
06:48 PM Tom_L: https://www.amazon.com/Starrett-Indicator-Dovetail-Attachments-Graduation/dp/B00BB0Z4FY/ref=pd_sbs_328_t_2/134-6921166-4139134?_encoding=UTF8&pd_rd_i=B00BB0Z4FY&pd_rd_r=007aef95-2b7e-40c2-9a52-ee00ff87a89c&pd_rd_w=lzKnE&pd_rd_wg=nNQEL&pf_rd_p=5cfcfe89-300f-47d2-b1ad-a4e27203a02a&pf_rd_r=QGM2KEVX61J4E783RF3J&psc=1&refRID=QGM2KEVX61J4E783RF3J
06:49 PM veegee: Yeah but what /is/ a "Last Word" indicator?
06:49 PM veegee: Is it just their branding or does it mean something?
06:49 PM Tom_L: just what some call them
06:50 PM Tom_L: .0005" typically
06:50 PM veegee: I have one of these: https://www.amazon.ca/gp/product/B003UATPG2/
06:50 PM veegee: how does it differ from the "last word" thing
06:50 PM Tom_L: yeah similar
06:50 PM Tom_L: mine has a dovetail on the back instead of the stem
06:51 PM veegee: OH you mean just use the indicator itself and rotate it around?
06:52 PM Tom_L: that's how i did it
06:52 PM veegee: with an extended tip like this: https://www.mscdirect.com/product/details/06442784
06:52 PM veegee: For now I just used a regular dial indicator and a holder arm clamped into an R8 drill chuck
06:53 PM Tom_L: https://www.youtube.com/watch?v=GtFTRyS__Yc
06:54 PM Tom_L: i think those little ones are more sensitive
06:58 PM veegee: Tom_L what kind of holder is that?
06:59 PM Tom_itx: just a ball with a dovetail
07:00 PM Tom_itx: the indicator has a dovetail on the top and back
07:03 PM veegee: For now I got it to within 30µm at a 15cm radius
07:03 PM Tom_itx: http://www.micro-machine-shop.com/Starrett%20711%20Series%20DTI.pdf
07:03 PM Tom_itx: similar to that one on the right
07:03 PM Tom_itx: i don't think they use dovetail on those
07:03 PM veegee: Ah I see it, thanks
07:04 PM Tom_itx: actually "B" at the bottom
07:04 PM veegee: I just realized that my mitutoyo indicator kit has a holder
07:04 PM veegee: I just never looked in the case after I took the indicator out
07:04 PM Tom_itx: mine may be mitutoyo, i forget
07:05 PM Tom_itx: i've got a couple of those
07:05 PM Tom_itx: https://www.carbideprobes.com/
07:05 PM Tom_itx: if you break a tip
07:28 PM veegee: carbide tips: if your indicator isn't reading what you want, just scratch the surface a little more ;)
07:30 PM Tom_itx: if your mics aren't reading what you want just turn the handle more
07:55 PM unterhaus: I used to do that twist the mic thing when I was working to really tight dimensions. Just to make myself feel better, because they weren't going back on the machine
07:56 PM unterhaus: that was such an annoying job, they couldn't get anyone to bid it
07:57 PM Tom_L: my kid's got a few of those
07:57 PM unterhaus: I always figured that if the only person that can do a machining job is a Ph.D. engineer, you might want to rethink the processes
07:58 PM Tom_L: yeah well get him out in the shop and see how far you get!
07:58 PM unterhaus: that was me
07:58 PM unterhaus: nobody else could do it
08:01 PM unterhaus: I know a batch of Ph.D.s that are pretty good machinists for weird processes. And probably wouldn't do that well in a regular machining job
08:50 PM unterhaus: I'm doing some work for a guy. He said he wanted me to use an XT computer, and I believed him
08:50 PM unterhaus: went looking for my dos disks
08:51 PM unterhaus: turns out he meant XP
08:55 PM TurBoss: that machines where fast
08:55 PM TurBoss: *went
09:00 PM unterhaus: are most people using 32 bit for linuxcnc? topic on email list prompts the question
09:07 PM CaptHindsight: yes
09:08 PM CaptHindsight: 64b support has been here for a while, but not popular yet
09:10 PM CaptHindsight: unterhaus: this project started in the 90's and was open sourced in the early 00's
09:10 PM CaptHindsight: was all 32b only until just a few years ago
09:10 PM unterhaus: I haven't thought about it for a while, I sort remember the decision to stay with 32 bit
09:11 PM CaptHindsight: then again i really can't say how mnay users have installed and not upgraded to anything released in the past few years
09:12 PM unterhaus: well, it looks like nobody with a PPMC has run 64 bit before
09:12 PM unterhaus: I am assuming Mesa is 64 bit safe
09:14 PM CaptHindsight: I don't recall hearing about any issues with Mesa and 64b
09:14 PM unterhaus: I hadn't heard about 64 bit problems at all, that's why I was assuming enough people were running it that the bugs were worked out
09:15 PM unterhaus: I have been monitoring the email lists for years, no discussion of 64 bit problems
09:16 PM unterhaus: the code originally wouldn't have been 64 bit safe at all
09:23 PM CaptHindsight: I only skimmed the discussion on the ML
09:24 PM CaptHindsight: The PPMC devices use a 24-bit hardware counter, and then rollover and extension to a 32-bit integer is handled in the ppmc driver.
09:34 PM unterhaus: the real issue is using a union of variables that don't have a fixed length across architectures
09:35 PM unterhaus: the assumption was made that it would be 32 bit.
09:35 PM unterhaus: which is funny, because the guy that probably wrote that was a big proponent of 64bit, IIRC
09:36 PM unterhaus: had his own version of emc2, don't remember what he called it
11:07 PM rtce9a: CaptHindsight, kernal version is "4.9.0-8-rt-amd64"
11:07 PM rtce9a: CaptHindsight, its still not working
11:10 PM CaptHindsight: rtce9a: does it get discovered by the kernel? lspci
11:11 PM rtce9a: CaptHindsight, yes but as "03:00.0 Serial controller: Device 1c00:3250 (rev 10) (prog-if 05 [16850])"
11:11 PM rtce9a: as a serial controller not parallel
11:12 PM CaptHindsight: ah Device 1c00:3250
11:13 PM CaptHindsight: parallel port + 2 serial ports when the Dev. ID is 3250
11:14 PM CaptHindsight: https://www.linux.org/threads/solved-unable-to-find-parallel-port-of-ch382_2s1p-on-linuxcnc-as-parport.24355/
11:15 PM CaptHindsight: "with dc00 where I was able to use this parallel port."
11:16 PM CaptHindsight: look at his lspci -v output https://www.linux.org/threads/solved-unable-to-find-parallel-port-of-ch382_2s1p-on-linuxcnc-as-parport.24355/#post-73324
11:17 PM CaptHindsight: I/O ports will be at two different addresses
11:17 PM CaptHindsight: the second one should be the LPT port
11:17 PM CaptHindsight: rtce9a: ^^^^
11:25 PM rtce9a: CaptHindsight, i follow his instruction and see if its connect
11:25 PM rtce9a: CaptHindsight, thanks for that
11:55 PM rtce9a: CaptHindsight, i think my par port is now connecting to breakout board, i created a stepconf wizard a hal file, when i toggle the ESTOP and power back on i here the relay clicking on the board
11:56 PM CaptHindsight: \0/
11:58 PM CaptHindsight: I have used a bunch of these, ~$9ea with shipping http://wiki.linuxcnc.org/cgi-bin/wiki.pl?WCH
